Some underground protection structures appear in the prior art, such as chinese patent with application number 201921019216.7 discloses an underground protection mechanism, and such as chinese patent with application number 202020367059.5 discloses a colliery safety protection support in the pit. The adjustability is poor, can't carry out quick, adaptability adjustment according to the change of working face, and this has influenced accommodation and installation effectiveness to a certain extent.

Disclosure of Invention

In view of this, the present invention provides an underground safety bin for underground protection, which has the advantages of good adjustability, wide application range and high installation efficiency.

The invention solves the problems through the following technical means:

the utility model provides an underground safety bin, includes the protection network and sets up the supporting component in the protection network four corners, the supporting component includes stand and stand position sleeve, the top of stand is passed through universal joint and is connected with the protection network, and the bottom and the stand position sleeve of stand are fixed to be cup jointed.

Further, the upright post is of a telescopic structure and is telescopically fastened through a telescopic fastener.

Further, the protection network includes first dictyosome and second dictyosome, the one end of first dictyosome is articulated with the one end of second dictyosome.

Further, the lateral parts of the first net body and the second net body are connected through an angle positioning rod, and two ends of the angle positioning rod are hinged with the first net body and the second net body respectively.

Further, the protective net is made of canvas and steel wire meshes.

Further, the bottom of the upright post locating sleeve is provided with a tip.

The invention has the beneficial effects that:

the utility model provides an underground safety storehouse, including the protection network and set up the supporting component in the protection network four corners, the supporting component includes stand and stand position sleeve, the top of stand is passed through universal joint and is connected with the protection network, and the bottom and the stand position sleeve of stand are fixed to be cup jointed. The utility model provides an underground safety storehouse, the stand passes through universal joint and is connected with the protection network, has improved the controllability of protection network greatly, and the installation angle of protection network can carry out quick, adaptability adjustment according to the change of working face, has improved accommodation and installation effectiveness greatly.

Drawings

The invention is further described below with reference to the figures and examples.

FIG. 1 is a schematic diagram of a state of the preferred embodiment of the present invention;

FIG. 2 is a schematic view of another state of the preferred embodiment of the present invention;

fig. 3 is a schematic diagram of the application of the present invention.

Detailed Description

The invention will be described in detail below with reference to the accompanying drawings, as shown in fig. 1-3: an underground safety bin comprises a protective net 5 and supporting components arranged at four corners of the protective net 5; the protective net 5 is made of canvas steel wire meshes, namely steel wires are penetrated into the canvas, so that the anti-smashing performance is excellent; the supporting component comprises a column 2 and a column positioning sleeve 1, wherein the column 2 is of a telescopic structure and is telescopically fastened through a telescopic fastener 4, and one preferable mode is as follows: the upright column comprises an upper column body and a lower column body which are sleeved in a sliding mode, and the upper column body and the lower column body are locked in a sliding mode through locking bolts; by adopting the telescopic upright posts, the installation height of the protective screening can be adjusted. The top of stand 2 is passed through universal joint 3 and is connected with protection network 5, and the bottom and the fixed cup joint of stand position sleeve 1 of stand 2, the bottom of stand position sleeve 1 is provided with most advanced 7, during specific installation, fixes a position the most advanced 7 of stand position sleeve 1 on pine stone or rock.

As a further improvement to the above technical solution, the protection net 5 includes a first net body 501 and a second net body 502, wherein one end of the first net body 501 is hinged to one end of the second net body 502 through a hinge shaft; the side parts of the first net body 501 and the second net body 502 are connected through an angle positioning rod 6, two ends of the angle positioning rod 6 are hinged to the first net body 501 and the second net body 502 respectively, the angle positioning rod is preferably a lockable telescopic rod type structure, and the protective net can be positioned and unfolded at a required angle. By adopting the structural design, the protective net can be unfolded at different angles according to the condition of the working face, and the width of the protective net can be adjusted, so that the application range of the protective net is greatly improved.

In summary, with the underground safety bin of the embodiment, on one hand, the stand column is connected with the protective net through the universal joint, so that the angle of the stand column can be adjusted according to the gradient, direction, transverse direction, longitudinal direction and the like during operation, the adjustability of the protective net is greatly improved, the installation angle of the protective net can be adjusted quickly and adaptively according to the change of a working surface, and the adaptation range and the installation efficiency are greatly improved; on the other hand, the height position and the unfolding angle of the protective net can be adaptively adjusted, so that the adaptive range and the installation efficiency are further improved.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
