Background

In the modern construction process, the bridge is widely applied to urban road construction in China as a building for crossing special geographic environments and providing space for other traffic. With the improvement of the life quality of people, automobiles become more and more transportation means for most people to go out, which leads to the continuous increase of the number of automobiles in China. With increasingly busy road traffic, bridges are widely used to relieve traffic pressure. The bridge can effectively relieve urban traffic pressure and improve urban operation efficiency, and becomes an indispensable part of social life. Just because the number of automobiles and the number of bridges are continuously increased, accidents that automobiles collide with piers also frequently occur. When an automobile collides with a bridge, once a bridge pier is damaged, the normal use of the bridge is seriously influenced, and the bridge maintenance cost, the reconstruction cost and the urban economic loss caused by road interruption are very huge. Therefore, people pay more attention to how to reduce the frequency of accidents caused by the collision of automobiles with the bridge piers, how to reduce the casualties during the accidents and how to protect the bridge piers. The anti-collision protection measures for the bridge pier are reasonably made, so that the anti-collision protection method is not only effective protection for the life of people, but also effective protection for the economic development of cities.

The traditional pier anti-collision measures mainly comprise three types: (1) directly pouring a reinforced concrete entity anti-collision platform at the bottom of the bridge; (2) complex mechanisms are arranged at the periphery of the bridge pier to directly resist the impact of the vehicle; (3) a rotatable device is arranged outside the bridge pier to consume the kinetic energy of the vehicle and change the running track of the vehicle through rotation. However, these anti-collision measures mainly have the following four defects: (1) the bearing platform directly poured at the bottom of the bridge can influence the stress performance of the bridge, and the reinforced concrete anti-collision platform outside the bridge pier cannot be replaced in time after being impacted and damaged; (2) whether the reinforced concrete is poured outside the pier or the complex anti-collision mechanism is arranged, the construction process is complex, the construction period is long, and the rapid traffic recovery of the city is not facilitated; (3) devices that use rotational energy and change the trajectory of the vehicle often fail to achieve their intended results due to the fact that they are bulky and have an internal structure that is not reasonable enough to actually rotate the device during a vehicle crash. (4) The truly rotatable anti-collision device may change the running track of the vehicle in the rotating process, and potential safety hazards are brought to people and vehicles in adjacent lanes.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention aims to provide a novel assembly type rotary energy consumption pier anti-collision device, which is used for solving the problems in the prior art, effectively dissipating the kinetic energy of a vehicle, stopping the vehicle after the vehicle rotates a certain angle and avoiding potential safety hazards; and the anti-collision device also has the characteristics of convenient and quick field construction, greatly shortened construction period, contribution to quick traffic recovery of cities and the like.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

As shown in fig. 1 to 7, the present embodiment provides a novel fabricated rotary energy-consuming pier collision avoidance device, which mainly comprises four parts: the first part is a rotating layer which surrounds the outermost side of the device and has light weight; the second part is an internal rigid layer which surrounds the outer side of the pier 0 and has heavier mass and higher rigidity; the third part is a rotation limiting mechanism for connecting the rotation layer and the rigid layer; the fourth section is a bottom rail floor.

The rotation layer is formed by splicing two cylinders with semicircular bottom surfaces through high-strength bolts, two cavities are arranged in the rotation layer, a bottom pulley is arranged at the bottom of the rotation layer, and the design content of each part of the rotation layer is introduced respectively as follows:

(1) the diameter of the bottom ring of the outermost chamber is small, and the bottom ring is formed by welding a first rotating layer steel plate 10, a second rotating layer steel plate 11, a middle rotating layer connecting steel plate 17, a bottom rotating layer steel plate 18 and an upper sealing steel plate on the periphery, the upper part and the lower part respectively. The chamber is filled with a quantity of lightweight energy-consuming deformable material. The first steel plate 10 and the second steel plate 11 of the rotating layer are made of stainless steel or low-yield-point steel into steel plates with concave-convex surfaces, and the yield strength of the low-yield-point steel plate is 100MPa, 160MPa or 225 MPa. By adopting stainless steel and low-yield-point steel, energy can be consumed through deformation of the external steel plate during impact, and the impact time is prolonged. Two arc-shaped rectangular rotating layer sliding doors 15 are made of steel plates at the positions, close to the middle connecting steel plate 17, of the rotating layer first steel plate 10, and when the sliding doors are opened, the sliding doors can be overlapped behind the rotating layer first steel plate 10. And filling light flexible energy-absorbing materials in a cavity between the first steel plate 10 of the rotating layer and the second steel plate 11 of the rotating layer, temporarily not filling the materials near the sliding door, and filling the vacant positions and closing the sliding door after the high-strength bolts 16 on the connecting steel plates 17 in the middle of the rotating layer are connected.

It is shown that the relief can increase the friction between the rotating layer and the vehicle. The thin stainless steel or the low-yield-point steel can enable the automobile to be embedded into the outer surface layer of the invention when the automobile impacts a structure, so that the rotating layer can better limit the movement of the automobile. The third steel plate 13 of the rotation layer, the middle connecting steel plate 17 of the rotation layer, and the upper and lower seal plates of the rotation layer are made of high-strength steel, such as Q460 steel, and the third steel plate 13 of the rotation layer is made of high-strength steel because it can provide sufficient reaction force for the external structure thereof. The middle connecting steel plate and the upper and lower seal plates of the rotating layer are made of high-strength steel because the high-strength steel can be matched with the third steel plate 13 of the rotating layer to provide effective boundary constraint for the first steel plate 10 of the rotating layer and the second steel plate 11 of the rotating layer, so that the first steel plate 10 of the rotating layer and the second steel plate of the rotating layer are subjected to reverse film tension after being impacted by a vehicle to enter the device through a film effect. Two arc-shaped dragging doors are arranged at the position, close to the middle connecting steel plate, of each semicircular cylinder body, so that the protruding bolts and the connecting steel plates are conveniently sealed in the outermost cavity after the bolts are installed, and potential safety hazards caused by the outward protruding bolts and the connecting steel plates are avoided.

(2) The diameter of the circular ring on the bottom surface of the inner cavity is larger, and the circular ring is formed by welding a second steel plate 11, a third steel plate, a middle connecting steel plate and an upper sealing plate and a lower sealing plate on a rotating layer on the periphery and the upper and the lower parts respectively. The cut scrap tires 12 are stacked in the chamber in a staggered layer-by-layer relationship with each tire being centered on the intersection of two tires on adjacent layers to facilitate resistance to vehicle impacts from different directions. Each tire needs to be cut into an arc shape with a certain central angle and then mutually extruded and stacked in the chamber, and each tire protrudes to the outer side, so that an effective buffer layer can be formed by the outward protruding radian of the tire and the mutual extrusion force between the inner parts. In addition, the waste tires 12 can be recycled, so that the purposes of energy conservation and environmental protection can be achieved while the cost is saved. The third steel plate 13 of the rotating layer should be made of high-strength steel, which can provide sufficient reaction force when the tire is impacted. On the outer wall that the third steel sheet is close to the rigid layer, the welding has 10 curved horizontal stiffeners 110, wherein installs one row of horizontal pulley 14 through rotating the round pin axle in the middle of per two horizontal stiffeners 110, and this horizontal pulley 14 is both favorable to rotating the layer and effectively rotates around the rigid layer outer wall, is convenient for again directly transmit the horizontal force that the layer received to rotate for the rigid layer.

(3) A circle of vertical pulleys 19 are arranged at the lower part of the rotating floor bottom plate, and compared with the traditional rotating anti-collision device, the bottom pulleys effectively reduce the friction between the device and the ground, so that the device can really and effectively rotate after being impacted. The internal rigid layer is formed by splicing two cylinders with semicircular bottom surfaces through high-strength bolts, and the rigid layer is formed by mutually welding a rigid layer first steel plate 22, a rigid layer second steel plate 24, a rigid layer middle connecting steel plate 21 with a middle part concave-convex shape and a rigid layer bottom steel plate 27 to form a cavity. In order to ensure that the transverse pulleys 14 on the rotating layer can smoothly rotate on the wall of the first steel plate 22 on the rigid layer, the middle connecting steel plate is arranged to be concave-convex. A steel bar is erected in the cavity of the rigid layer at intervals, the vertical steel bars are fixedly connected with the upper steel bar fixing steel sheet 23, and the middle of each vertical steel bar is provided with a transverse annular stirrup, so that the whole impact resistance of the rigid layer is conveniently provided. Other residual spaces of the cavity are filled with concrete, and at the moment, the external steel plate can be used as a template in concrete pouring, and the deformation capacity and the shock resistance of the whole rigid layer can be improved. 5T-shaped steel plates are welded on the outer wall of one side, close to the pier, of each second steel plate of each rigid layer, and the T-shaped steel plates can enhance the overall stability of the rigid layers. The rigidity layer is because its rigidity is big and overall stability is strong, can provide sufficient reaction force and support for rotating the layer when whole device receives the striking, guarantees to rotate in the layer elastic material can the full play effect, makes the pier not receive the striking and damages.

The rotation limiting mechanism is composed of a spring 31 and a spring hook 32, and a vertical spring is installed between vertical gaps of the transverse pulleys 14 on each layer of the rotating layer and the rigid layer and forms an angle of 45 degrees with the axis of the device in the horizontal direction. The bottom of the spring 31 is connected with the rotating layer, the top of the spring 31 is connected with the rigid layer, when the device rotates, the pulling force generated by the spring 31 is gradually increased along with the increase of the rotating angle, the pulling force of the rotating layer reaches the maximum after the rotating layer rotates for 90-120 degrees by controlling the rigidity and the length of each spring 31, and at the moment, the rotating layer cannot continue to rotate. The kinetic energy of the vehicle can be consumed to stop the vehicle by the tension of the spring 31 and the rotation of the rotating layer when the vehicle collision occurs.

The bottom track is a U-shaped track formed by welding five steel plates, and specifically, the bottom track bottom plate is a U-shaped track formed by sequentially welding two bottom track upper steel plates 41 with different diameters, two bottom track side steel plates 42 with different diameters and a bottom track lower steel plate 40 from inside to outside. And then is connected and fixed with the ground through the bottom track fixing bolt 43. U-shaped track recess embedding ground in, its size and the adaptation of bottom vertical pulley, vertical pulley 19 can roll in the track of below ground, can effectively strengthen the overall stability of rotating the layer. The height of the steel plates on the two sides of the vertical pulley 19 is accurately measured and calculated, so that a small gap can be formed between the steel plates and the ground after the vertical pulley 19 is placed into a rail, a tighter device can be formed by rolling on a rail bottom plate compared with the situation that the pulley directly rolls on the ground, and the phenomenon that external garbage enters the device and the pulley normally slides due to the influence of the inside of the device can be effectively prevented.

In this embodiment, the empty positions of the first chamber and the second chamber of the rotation layer may be filled with light flexible energy-absorbing deformation materials such as foamed aluminum or foam. The waste tire 12 can be cut into a complete tire with a central angle of 120 degrees, 150 degrees, 180 degrees and the like, and the complete tire is mutually extruded and stacked in a staggered way. The two ends of the spring 31 for limiting rotation are hooked on the spring hooks 32, in the gap between every two transverse pulleys 14, the spring hook 32 on one side of the rotating layer is installed at the bottom of the gap, the spring hook 32 on one side of the rigid layer is installed at the top of the gap, and finally the spring 31 is vertically hooked on the two spring hooks 32.

The periphery and the bottom surface of the rigid layer are formed by welding steel plates, a reinforced concrete structure is poured inside the rigid layer, and an upper sealing plate can not be arranged at the upper part of the rigid layer; furthermore, a plurality of drain holes are arranged on the bottom steel plate of the U-shaped track for draining water.
