Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining safety facilities technology, and in particular to an anti-collision device for safety management. Background Technology
[0002] To facilitate the transportation of mine cars to and from the mine, mine car lanes are usually opened up underground. In order to improve the safety of mine car operation and reduce the accident rate, anti-collision equipment is installed at the base of the walls on both sides of the lane, especially at the bends, to prevent mine cars from hitting the walls and causing accidents when turning.
[0003] Collision avoidance is a crucial aspect of safety management in underground coal mines. Currently, most collision avoidance devices are roller-shaped, fixed to the base of the mine tunnel wall using mounting plates and expansion bolts, acting as a buffer in the event of a mine car collision. However, the collision avoidance devices currently used in mines have an integrated structure where the roller body and the mounting plate on the back are not removable. This hinders installation. During installation, the mounting plate is attached to the base of the wall, requiring a set of expansion bolts to be driven into the plate at both the top and bottom. While the bolts at the top encounter less resistance during driving, the lower bolts, already positioned low, are further hampered by the roller itself, making disassembly and assembly inconvenient. Furthermore, damage to the collision avoidance device necessitates complete replacement, resulting in high costs. Utility Model Content

[0044] like Figures 1-4 As shown, this utility model provides a collision avoidance device for safety management, which has a first direction X, a second direction Y and a third direction Z that intersect each other.
[0045] In some implementations, the first direction X, the second direction Y, and the third direction Z intersect each other perpendicularly.
[0046] In some implementations, the safety management anti-collision device includes a mounting assembly 10 and an anti-collision assembly 20. For example, in a mine tunnel, the mounting plate 11 is mounted on the tunnel wall.
[0047] Specifically, the mounting assembly 10 includes a mounting plate 11, a mounting frame 13, and a first fastener 15. The mounting frame 13 is located on one side of the mounting plate 11 along the second direction Y, and the first fastener 15 is located on the mounting frame 13. The anti-collision assembly 20 includes a plastic panel 21 and a back plate connecting member 22. The back plate connecting member 22 is located on the side of the plastic panel 21 facing the mounting assembly 10. The back plate connecting member 22 is connected to the mounting frame 13 through the first fastener 15. Thus, by setting the back plate connecting member 22 on the plastic panel 21, the back plate connecting member 22 can be detached and connected to the mounting frame 13 through the first fastener 15. When the plastic panel 21 or the rubber buffer roller 24 is damaged by collision, the anti-collision assembly 20 can be disassembled and replaced separately without disassembling the mounting assembly 10, which can improve operating efficiency and reduce the difficulty of subsequent disassembly and assembly.
[0048] In some embodiments, to facilitate the installation of the mounting plate 11 on the mine wall, the mounting assembly 10 further includes a second fastener 12, which passes through the mounting plate 11 along the second direction Y, and the mounting plate 11 can be fixed to the mine wall by means of the second fastener 12.
[0049] In some embodiments, the second fasteners 12 are located at the four corners of the mounting plate 11 to ensure the stability and balance of the mounting plate 11 after installation and to prevent it from falling off after a collision.
[0050] In some embodiments, the mounting frame 13 is provided with a first threaded groove 14 extending along a first direction X; the back plate connecting member 22 includes a back plate 221 and a mating plate 222, the back plate 221 is located on the side of the plastic panel 21 facing the mounting assembly 10; the mating plate 222 is located on the side of the back plate 221 facing away from the plastic panel 21, the mating plate 222 is fitted into the mounting frame 13 along a second direction Y, the mating plate 222 is provided with a first connecting groove 223 extending along the first direction X, along the first direction X, the first threaded groove 14 corresponds to the first connecting groove 223, and the first fastening... The component 15 passes through the first screw groove 14 and the first connecting groove 223 along the first direction X. Thus, during installation, it is only necessary to align the mating plate 222 with the mounting frame 13 along the second direction Y and insert it, and then lock it with the first fastener 15. During disassembly, it is only necessary to remove the first fastener 15 and pull out the mating plate 222 along the second direction Y. During this process, the mounting plate 11 and the mounting frame 13 are fixed to the mine wall as a whole. After the anti-collision component 20 is damaged, it only needs to be disassembled and replaced separately. The mounting component 10 can be recycled, reducing the replacement cost.
[0051] In some embodiments, to ensure the connection strength between the mounting plate 11 and the mounting frame 13, multiple first screw grooves 14 are arranged at intervals along the third direction Z. The number of first connecting grooves 223 corresponds to the number of first screw grooves 14. By setting multiple connection points, the connection strength between the mounting plate 11 and the mounting frame 13 can be improved, and the mounting frame 13 can be prevented from falling off during collisions.
[0052] In some embodiments, the plastic panel 21 acts as a buffer upon impact, reducing the impact force. To further improve the buffering effect, the anti-collision assembly 20 also includes a rubber buffer roller 24. The plastic panel 21 has a receiving cavity 211, and the plastic panel 21 has a shaft 23 extending through the receiving cavity 211 along the third direction Z. The rubber buffer roller 24 is rotatably mounted on the shaft 23, located within the receiving cavity 211, and at least partially protruding outside the receiving cavity 211. Thus, the rubber buffer roller 24 at least partially protruding outside the receiving cavity 211 ensures that the direction of force can be changed during a collision by rotating the rubber buffer roller 24, further reducing the impact and minimizing collision damage and loss.
[0053] In some embodiments, the plastic panel 21 has second connecting grooves 212 on opposite sides along the third direction Z; the anti-collision component 20 also includes an anti-loosening nut 25, a limiting plate 26, and a third fastener 27. The plastic panel 21 has limiting plates 26 on opposite sides along the third direction Z. The limiting plates 26 have second threaded grooves 261. Along the third direction Z, the second threaded grooves 261 correspond one-to-one with the second connecting grooves 212. Along the third direction Z, the shaft 23 passes through at least partially through the limiting plates 26; the third fastener 27... The second threaded groove 261 and the second connecting groove 212 are connected along the third direction Z; further, the plastic panel 21 is provided with elongated grooves 213 on opposite sides along the third direction Z, the elongated grooves 213 communicate with the receiving cavity 211, and the elongated grooves 213 extend along the second direction Y; along the third direction Z, the two ends of the shaft 23 are provided with threaded ends 231, the shaft 23 is connected to the elongated grooves 213 along the third direction Z, and at least a portion of the threaded ends 231 extends to the outside of the plastic panel 21, and the anti-loosening nut 25 is connected to the threaded ends 231; further... Furthermore, the limiting plate 26 is also provided with a limiting groove 262. Along the third direction Z, the orthographic projection of the limiting groove 262 at least partially overlaps with the orthographic projection of the elongated groove 213. The threaded end 231 passes through the limiting groove 262 along the third direction Z. The limiting groove 262 has an opening 262a on the side away from the back plate connecting member 22, so that the limiting groove 262 forms a semi-closed limiting groove. In this way, when the mine car crashes, the plastic panel 21 and the rubber buffer roller 24 impact each other directly. When the rubber buffer roller 24 is damaged or the shaft 23 is bent, it needs to be closed. When replacing, first loosen and remove the third fastener 27 on the limit plate 26. The third fastener 27 will disengage from the second connecting groove 212 and the second screw groove 261, and the limit plate 26 can be removed. The limit groove 262 will no longer block the long groove 213, allowing the long groove 213 to be fully exposed, providing sufficient room for the bent shaft 23 to move. Then loosen and remove the anti-loosening nuts 25 at both ends of the shaft 23. Use a knife to cut and remove the rubber buffer roller 24, and then pull the bent shaft 23 out of the long groove 213.
[0054] In some embodiments, the anti-collision component 20 further includes two sets of fasteners and nylon straps 29. The two sets of fasteners are located on the side of the plastic panel 21 away from the back panel connecting member 22. The two sets of fasteners are located on opposite sides of the receiving cavity 211 along the first direction X. Each set of fasteners includes two fixing heads 28, which are spaced apart along the third direction Z. The nylon straps 29 extend along the third direction Z and are connected to the two fixing heads 28 of each set of fasteners. The fixing heads 28 provide physical support for the installation and fixation of the nylon straps 29. The nylon straps 29 facilitate the lifting and transportation of the anti-collision component 20 and provide a gripping point for the installer during installation. The installer can grab the nylon straps 29 on both sides and pull upward to lift the anti-collision component 20 directly and quickly complete the connection.
[0055] In some embodiments, to further reduce the impact force of a collision, the rubber buffer rollers 24 are at least two, and the at least two rubber buffer rollers 24 are arranged at a Z-interval along the third direction on the shaft 23.
[0056] The working process of this utility model is as follows: Please refer to... Figures 1-4 understand,
[0057] In use, the mounting plate 11 is fixed to the mine wall using the second fastener 12, the docking plate 222 is aligned with the mounting frame 13 along the second direction Y and inserted, and then locked using the first fastener 15. In disassembly, simply remove the first fastener 15 and pull out the docking plate 222 along the second direction Y. During this process, the mounting plate 11 and the mounting frame 13 are fixed to the mine wall as a whole. If the anti-collision component 20 is damaged, it only needs to be disassembled and replaced separately, reducing the difficulty of disassembly and assembly in the later stage.
[0058] When the mine car crashes, the plastic panel 21 and the rubber buffer roller 24 impact each other directly. When the rubber buffer roller 24 is damaged or the shaft 23 is bent and needs to be replaced, first loosen and remove the third fastener 27 on the limit plate 26. The third fastener 27 will disengage from the second connecting groove 212 and the second screw groove 261, and the limit plate 26 can be removed. The limit groove 262 will no longer block the long groove 213, so that the long groove 213 is fully exposed, providing sufficient space for the bent shaft 23 to move. Then loosen and remove the anti-loosening nuts 25 at both ends of the shaft 23. Use a knife to cut and remove the rubber buffer roller 24. Then pull the bent shaft 23 out from the long groove 213 along the third direction Z.
[0059] As the mounting plate 11 is fixed to the mine wall, the installer grabs the nylon straps 29 on both sides and pulls them upwards to lift the anti-collision component 20 directly, quickly completing the connection. The nylon straps 29 facilitate the application of force when transporting the anti-collision component 20.
[0060] In summary, the anti-collision device for safety management provided by this utility model, by setting an installation frame 13 on the mounting plate 11 and a back plate connecting member 22 on the plastic panel 21, allows the back plate connecting member 22 to be detachably connected to the mounting frame 13 through the first fastener 15. When the plastic panel 21 or the rubber buffer roller 24 is damaged by collision, the anti-collision component 20 can be disassembled and replaced separately without disassembling the installation component 10, which can improve the operation efficiency and reduce the difficulty of subsequent disassembly and assembly. In addition, the plastic panel 21 can play a buffering role when impacted, and the rubber buffer roller 24 can change the direction of force by rotating to further reduce the impact. Moreover, the design of the nylon cloth belt 29 facilitates the transportation and installation of the anti-collision component 20.
