The two situations have great defects, the reliability of the system is seriously reduced, frequent maintenance is needed, a large amount of manpower and material resources are consumed, and the later maintenance and repair cost is higher.

First embodiment

Referring to fig. 1, in the embodiment of the present application, a high pressure pipeline anti-loosening clamp 10 is provided, and the high pressure pipeline anti-loosening clamp 10 is configured to be assembled in a high pressure pipeline to ensure stability of the high pressure pipeline, so as to achieve the purposes of improving reliability, reducing maintenance difficulty, and saving cost. The high-pressure pipeline can be a high-pressure inter-cooling pipeline of the diesel generator set, and can also be a high-pressure pipeline in other equipment.

Wherein the high pressure line comprises a hose 12 and two tubular structures 11. The two tubular structures 11 may refer to two high pressure metal pipes which may be configured to be suitable for the transport of high pressure, high temperature and highly viscous media. And, the hose 12 is configured to connect the two tubular structures 11 so that the two tubular structures 11 are in a communicating state. In the prior art, a flange or a rubber pipe is generally adopted to connect two high-pressure metal pipes, but the flange needs a high-precision assembly design and can only be applied to large-scale equipment; and the rubber tube connection easily causes the looseness of two high-pressure metal tubes. Therefore, in the prior art, the connection stability between the two metal pipes and the connection cost of the two high-pressure metal pipes cannot be compatible.

In order to improve above-mentioned problem, in other words, in order to improve the problem that the connection stability between two high-pressure metal pipes and the connection cost of two high-pressure metal pipes can't compromise among the prior art, provide the locking clamp 10 that takes off of high-pressure pipeline in this application embodiment, this locking clamp 10 that takes off of high-pressure pipeline can realize improving the reliability, reduces the maintenance degree of difficulty, saves the cost.

Referring to fig. 1 and 2, the anti-release clamp 10 for high-pressure pipes includes a first clamp 100, a second clamp 200, and a connecting member 300. The first and second clips 100, 200 are configured to fit over the ends of the hose 12, respectively, and the first and second clips 100, 200 are configured to grip the hose 12. In other words, in the case where the two tubular structures 11 are connected by the hose 12, for example, the two high-pressure metal pipes are connected by a rubber pipe. The first and second clips 100 and 200 can be clamped to both ends of the hose 12, respectively, so that one end of the hose 12 can be clamped by the first clip 100, and the other end of the hose 12 can be clamped by the second clip 200, thereby improving the connection stability between the hose 12 and the two tubular structures 11, and improving the sealing performance between the hose 12 and the tubular structures 11.

In addition, both ends of the connector 300 are connected to the first clip 100 and the second clip 200, respectively. Therefore, the relative position stability between the first clamp 100 and the second clamp 200 can be ensured through the connecting piece 300, so that the relative position of the first clamp 100 and the second clamp 200 is stable, and under the condition that the two tubular structures 11 are subjected to the acting force to enable the two tubular structures 11 to approach to each other or to be away from each other, the acting force can be shared by the connecting piece 300, so that the first clamp 100 and the second clamp 200 can be prevented from approaching to each other or being away from each other, the hose 12 can be prevented from loosening from the two tubular structures 11, and the connection stability of the high-pressure pipeline can be improved. Meanwhile, the first clamp 100, the second clamp 200 and the connecting piece 300 can be easily disassembled, so that the difficulty of maintaining the high-pressure pipeline is reduced, the maintenance efficiency is improved, and the cost is reduced. In addition, the anti-loosening hoop 10 for the high-pressure pipeline is simple in structure and easy to achieve, and manufacturing cost and assembly cost are reduced. In conclusion, the anti-loose clamp 10 for the high-pressure pipeline provided by the invention can achieve the purposes of improving the reliability, reducing the maintenance difficulty and saving the cost.

For example, when a force is applied to one of the two tubular structures 11, such that the tubular structure 11 has a tendency to move away from the other tubular structure 11, the tubular structure 11 transmits the force to the connecting member 300 through the first clip 100, and the connecting member 300 transmits the force directly to the other tubular structure 11 through the second clip 200, so that the two tubular structures 11 are prevented from pulling the hose 12, the hose 12 is ensured not to be interfered by the external force, and the stability of the connection of the hose 12 to the two tubular structures 11 is ensured. In the same way, in the case that the two tubular structures 11 are subjected to a force such that the two tubular structures 11 have a tendency to move closer together, one of the tubular structures 11 transmits the force to the connecting member 300 through the first clamp 100, and the connecting member 300 transmits the force to the other tubular structure 11 through the second clamp 200, so that the hose 12 is not affected by the force, thereby ensuring that the hose 12 is stably fitted between the two tubular structures 11 and improving the connection stability of the two tubular structures 11.

Optionally, in some embodiments of the present application, the connector 300 includes a first connector 310, a second connector 320, and a fastener 330. The first connection portion 310 is connected to the first yoke 100, and the second connection portion 320 is connected to the second yoke 200; the first connection portion 310 and the second connection portion 320 are detachably connected by a fastener 330. In the assembling process, the first clamp 100 and the second clamp 200 may be assembled to both ends of the hose 12, respectively, such that the first connection portion 310 and the second connection portion 320 correspond to each other, and then the first connection portion 310 and the second connection portion 320 are connected by the fastening member 330, so that the assembling of the high-pressure pipeline anti-loose clamp 10 is completed.

It should be understood that in other embodiments of the present application, the connecting member 300 may be arranged differently, for example, the connecting member 300 may include only the first connecting portion 310, one end of the first connecting portion 310 is connected to the first band 100, and the other end of the first connecting portion 310 may be detachably connected to the second band 200 by the fastening member 330, so as to assemble the first band 100 and the second band 200. For another example, the connector 300 may include only the second connection part 320, one end of the second connection part 320 being connected to the second yoke 200, and the other end of the second connection part 320 being detachably connected to the first yoke 100, thereby achieving the assembly of the first and second yokes 100 and 200. Also for example, both ends of the connector 300 are detachably connected to the first clip 100 and the second clip 200, respectively, etc.

In some embodiments of the present application, one end of the first connection portion 310 is connected to the first yoke 100, and the other end is bent to form a first mating portion 311; the second connecting portion 320 is connected to the second yoke 200, and the other end is bent to form a second engaging portion 321. In other words, the first coupling portion 311 is formed by bending an end portion of the first connection portion 310 away from the first yoke 100, and the second coupling portion 321 is formed by bending an end portion of the second connection portion 320 away from the second yoke 200, so as to facilitate the coupling between the first connection portion 310 and the second connection portion 320. It should be noted that, when the first engagement portion 311 and the second engagement portion 321 are connected by the fastening member 330, the first engagement portion 311 and the second engagement portion 321 are attached to each other, so that the connection stability between the first engagement portion 311 and the second engagement portion 321 is improved, and the connection member 300 can improve the connection stability between the first clamp 100 and the second clamp 200.

Alternatively, wherein the fastening member 330 is a connector 300 such as a bolt, the fastening member 330 penetrates the first fitting portion 311 and the second fitting portion 321 to detachably fit the first fitting portion 311 and the second fitting portion 321; meanwhile, holes adapted to the bolts are formed in the first and second fitting portions 311 and 321, so that the bolts can pass through the holes conveniently. It should be understood that in other embodiments of the present application, the first matching portion 311 and the second matching portion 321 may be assembled with each other in other manners, for example, a latch is disposed on the first matching portion 311, and the second matching portion 321 is provided with a hook matched with the latch, so that the first matching portion 311 and the second matching portion 321 are clamped by a hook; for another example, the first engaging portion 311 is provided with a locking hole, the second engaging portion 321 is provided with a locking block, and the locking block penetrates the locking hole to be locked and engaged with the first engaging portion 311.

In order to improve the stability of the first and second clamp 100 and 200, optionally, in some embodiments of the present application, the high-pressure pipeline anti-release clamp 10 includes a plurality of connecting members 300, the plurality of connecting members 300 are equally spaced in the circumferential direction of the first clamp 100, and the plurality of connecting members 300 are equally spaced in the circumferential direction of the second clamp 200. Based on this, uniform force can be provided to the first and second clips 100 and 200 through the plurality of connectors 300, thereby ensuring that the first and second clips 100 and 200 can be stably clamped to the hose 12. In addition, in some embodiments of the present application, the plurality of connection members 300 may extend in a direction parallel to the axis of the first band 100, so that the plurality of connection members 300 may provide a force to the first band 100 and the second band 200 parallel to the axis of the first band 100, and may ensure stability of the first band 100 and the second band 200.

In addition, the connector 300 is attached to the outside of the first clip 100, and/or the connector 300 is attached to the outside of the second clip 200. Note that the outer side of the first clamp 100 indicates the side of the first clamp 100 away from the hose 12, and may also be regarded as the outer circumference of the first clamp 100; the outer side of the second clip 200 represents the side of the second clip 200 that is away from the hose 12 and may also be considered the outer circumference of the second clip 200. Of course, the connector 300 may be connected to one axial side of the first yoke 100 or one axial side of the second yoke 200. In other words, "and/or" means that one end of the connector 300 is connected to the outside of the first band 100, and the other end is connected to one side of the second band 200 in the axial direction; alternatively, one end of the connector 300 is connected to the outside of the second yoke 200, and the other end of the connector 300 is connected to one side of the first yoke 100 in the axial direction; alternatively, both ends of the connector 300 are connected to the outside of the first clip 100 and the outside of the second clip 200, respectively. Of course, the side of the first band 100 in the axial direction means the side of the first band 100 in the axial direction thereof, in other words, the side of the first band 100 adjacent to the second band 200; the side of the second band 200 in the axial direction represents a side of the second band 200 in the axial direction thereof, in other words, a side of the second band 200 adjacent to the first band 100.

Wherein, the connection of the connector 300 to the outside of the first yoke 100 can increase the contact area between the first yoke 100 and the connector 300, thereby improving the connection stability between the first yoke 100 and the connector 300; furthermore, a gap is formed between the connector 300 and the hose 12, so that the connector 300 is prevented from interfering with the clamping of the hose 12 by the first clamp 100. Similarly, the connection of the connector 300 to the outside of the second yoke 200 may increase the contact area between the second yoke 200 and the connector 300, thereby improving the connection stability between the second yoke 200 and the connector 300; furthermore, a gap is formed between the connector 300 and the hose 12, so that the connector 300 is prevented from interfering with the clamping of the hose 12 by the second clamp 200.

The hose 12 is clamped by the joint clamping action of the first hoop sheet 110 and the second hoop sheet 120, so that the first hoop 100 can be conveniently adapted to hoses 12 with various diameters, and the universality of the high-pressure pipeline anti-loosening hoop 10 is improved. In a similar way, the joint clamping action of the third hoop sheet 210 and the fourth hoop sheet 220 clamps the pipe, which facilitates the second hoop 200 to be applied to hoses 12 with various diameters, thereby improving the universality of the anti-loose hoop 10 for high-pressure pipelines.

It should be understood that in other embodiments of the present application, the first and second clamp bands 100 and 200 may include a greater number of clamp segments, and that, in the case of hoses 12 of different diameters, an appropriate number of clamp segments may be selected to clamp the hose 12.

Alternatively, in the case where the first and second hoop sheets 110 and 120 are fitted to each other, the first and second connection pieces 111 and 121 may be attached to each other, whereby stability between the first and second hoop sheets 110 and 120 may be improved. Similarly, under the condition that the third hoop sheet 210 and the fourth hoop sheet 220 are matched with each other, the third connecting sheet 211 and the fourth connecting sheet 221 are attached to each other, so that the connection stability of the third hoop sheet 210 and the fourth hoop sheet 220 is improved. Of course, in other embodiments, in the case of a larger diameter of the tubular structure 11, a certain gap may be formed between the first connecting piece 111 and the second connecting piece 121, and similarly, a certain gap may be formed between the third connecting piece 211 and the fourth connecting piece 221.

Additionally, in some embodiments of the present application, the first clip 100 is a resilient structure; and/or the second clip 200 is of a resilient construction. Here, "and/or" indicates that only the first band 100 may be of an elastic structure, only the second band 200 may be of an elastic structure, and of course, both the first band 100 and the second band 200 may be of an elastic structure. The first clamp 100 and the second clamp 200 are both elastic structures, and both the first clamp 100 and the second clamp 200 have elasticity, so that the diameter range of the hose 12 which is allowed to be clamped by the first clamp 100 can be enlarged through the elastic deformation of the first clamp 100, and similarly, the diameter range of the hose 12 which is clamped by the second clamp 200 can be enlarged through the elastic deformation of the second clamp 200. Alternatively, the first band 100 may have an elastic structure, and the first band piece 110 and the second band piece 120 may have an elastic structure; the second yoke 200 is of an elastic structure, and the third yoke piece 210 and the fourth yoke piece 220 are of an elastic structure.

In summary, the anti-loose clamp 10 for high-pressure pipelines provided in the embodiment of the present application can reinforce the connection stability of one end of the hose 12 with one of the tubular structures 11 through the first clamp 100, and reinforce the connection stability of the other end of the hose 12 with the other tubular structure 11 through the second clamp 200; meanwhile, the relative position stability between the first clamp 100 and the second clamp 200 is ensured through the connecting member 300, so that the relative position of the first clamp 100 and the second clamp 200 is stable, and under the condition that the two tubular structures 11 are subjected to the acting force to enable the two tubular structures 11 to approach to each other or to be away from each other, the acting force can be shared by the connecting member 300, so that the first clamp 100 and the second clamp 200 can be prevented from approaching to each other or being away from each other, the hose 12 can be prevented from loosening from the two tubular structures 11, and the connection stability of the high-pressure pipeline is improved. Meanwhile, the first clamp 100, the second clamp 200 and the connecting piece 300 can be easily disassembled, so that the difficulty of maintaining the high-pressure pipeline is reduced, the maintenance efficiency is improved, and the cost is reduced. In addition, the anti-loosening hoop 10 for the high-pressure pipeline is simple in structure and easy to achieve, and manufacturing cost and assembly cost are reduced. In conclusion, the anti-loose clamp 10 for the high-pressure pipeline provided by the invention can achieve the purposes of improving the reliability, reducing the maintenance difficulty and saving the cost.
