[0002] Nylon, Chinese name polyamide, nylon series is an important engineering plastic. Nylon materials have excellent mechanical strength, rigidity, toughness, mechanical shock absorption and wear resistance. Nylon plates are generally used on mining machines to receive the fallen ore, which can play a certain buffering role. At the same time, the nylon plates can be replaced to reduce the impact of the ore falling on the mining machine and improve the service life of the mining machine. Nylon plates are generally installed on the top receiving trough of the mining machine. People insert the threaded rod on the mining machine into the mounting hole on the nylon plate. Because the threaded column and the mounting hole are interference fit, the staff needs to use a heavy hammer to hammer on the nylon plate during installation to insert the threaded rod into the mounting hole of the nylon plate. Due to the large number of threaded rods, when hammering, the installation of a threaded column often requires the staff to hammer multiple times to make the threaded rod firmly inserted into the mounting hole, which will lead to greater labor intensity and low work efficiency for the staff.

[0020] Reference Figure 1-6 The present invention provides a wear-resistant nylon top slide structure for a mining machine, comprising a nylon slide 1 and a threaded rod, wherein:

[0021] A plurality of mounting holes 2 are provided on one side of the nylon skateboard 1, and the threaded rods are detachably inserted into the mounting holes 2 and the threaded rods and the mounting holes 2 are transitionally matched, and a one-way locking anti-slip mechanism is installed in the mounting holes 2;

[0022] When people install the nylon skateboard 1, they can place the nylon skateboard 1 on the top of the mining machine so that the threaded columns on the mining machine are inserted into the mounting holes 2 one by one. When people hammer the nylon skateboard 1 with a hammer, because the mounting hole 2 and the threaded rod are transition fit or clearance fit, when hammering, the threaded column can be quickly inserted into the mounting hole 2, which can reduce people's labor intensity and improve people's work efficiency. When in use, the one-way locking anti-slip mechanism can lock the position of the threaded column in the mounting hole 2, which can reduce the nylon skateboard 1 from falling off the threaded column and ensure the firmness and stability of the installation of the nylon skateboard 1.

[0023] In a specific embodiment, the one-way locking anti-slip mechanism includes a locking block 3 and a torsion spring 4; the inner wall of the mounting hole 2 is provided with a receiving groove 5 for receiving the locking block 3, the locking block 3 is rotatably connected in the receiving groove 5 through a rotating shaft, and the torsion spring 4 is sleeved on the rotating shaft;

[0024] When installing the nylon skateboard 1, the threaded columns on the mining machine are matched one by one with the mounting holes 2 on the nylon skateboard 1, and people then use a hammer to hammer on the nylon skateboard 1, and the nylon skateboard 1 is quickly sleeved on the threaded columns. When the threaded column is inserted into the mounting hole 2, the threaded column pushes the positioning block 3 to rotate and be received in the receiving groove 5, which can facilitate the normal insertion of the threaded column without obstruction. When the threaded column is fully inserted into the mounting hole 2, the positioning block 3 is driven to rotate and rest against the thread teeth on the outer wall of the threaded column under the action of the torsion spring 4. When the threaded column is to be pulled out, the positioning block 3 will rest against the thread teeth to limit the threaded column from leaving the mounting hole 2, which can ensure the stability and firmness of the installation of the nylon skateboard 1, and reduce people's labor intensity through a simple structure.

[0025] In a specific embodiment, the positioning block 3 has a first position state in which it is received in the receiving groove 5 and a second position state which is perpendicular to the inner wall of the mounting hole 2 and extends into the mounting hole 2;

[0026] When the threaded column is inserted into the mounting hole 2, the threaded column will push the locking block 3 to be stored in the storage groove 5, which is convenient for the insertion of the threaded column, reduces people's labor intensity and improves people's work efficiency. When the threaded column is pulled out, the locking block 3 will be stuck between the thread teeth of the outer wall of the threaded column, which can limit the pulling out of the threaded column and ensure the stability and firmness of the installation of the nylon skateboard 1.

[0027] In a specific embodiment, a fracture opening 6 is provided on the positioning block 3 and the fracture opening 6 is located at a section of the positioning block 3 that is always located in the receiving groove 5; when the nylon skateboard 1 is worn out too much and people need to dismantle the nylon skateboard 1 for replacement, people can use tools to exert a certain force to lift the nylon skateboard 1, and when the nylon skateboard 1 is lifted, the positioning block 3 is engaged with the thread teeth of the outer wall of the threaded column, and when the lifting force reaches a certain amount, the positioning block 3 will be broken from the fracture opening 6, and after the positioning block 3 is broken from the fracture opening 6, the remaining section that is still rotating in the receiving groove 5 is too short and will not rest on the thread teeth of the threaded column, which can ensure the removal of the threaded column, and people can then replace the new nylon skateboard 1 and install it, without causing trouble to people's disassembly.

[0028] In a specific embodiment, a plurality of buffer mechanisms are installed on one side of the nylon slide 1 close to the mounting hole 2; when the ore falls and hits the nylon slide 1, the buffer mechanism will play a buffering role, thereby increasing the service life of the nylon slide 1 and reducing the occurrence of rapid wear caused by direct squeezing between the nylon slide 1 and the mining machine due to the long-term impact of the ore.

[0029] In a specific embodiment, the buffer mechanism includes a buffer block 7 and a No. 1 spring 8; a buffer groove slidably matched with the buffer block 7 is provided on one side of the nylon slide plate 1 close to the mounting hole 2, and side slide grooves 9 are provided on both sides of the buffer block 7, and a side slider 10 slidably matched with the side slide groove 9 is connected to the inner wall of the buffer groove, and the No. 1 spring 8 is installed in the buffer groove and one end of the No. 1 spring 8 is connected to the buffer block 7;

[0030] When the ore falls onto the nylon slide 1, the nylon slide 1 is impacted by the ore and moves downward, so that when the nylon slide 1 moves downward, the buffer block 7 extending out of the buffer groove first contacts the mining machine and retracts into the buffer groove, and then the No. 1 spring 8 plays a buffering role, which reduces the nylon slide 1 from directly colliding with the mining machine and being squeezed to cause more serious wear. The two sides of the buffer block 7 are sliding in the side slide groove 9 by the side sliders 10, which can limit the sliding position of the buffer block 7 and prevent the buffer block 7 from falling out of the buffer groove, ensuring that the buffer effect can always be achieved.

[0031] In a specific embodiment, the buffer mechanism further includes a buffer column 11 and a No. 2 spring 12; a telescopic groove slidably matched with the buffer column 11 is provided on a side of the buffer block 7 away from the nylon slide plate 1, a diffusion groove is circumferentially provided on the inner wall of the telescopic groove, the buffer column 11 is circumferentially connected with a boss slidably matched with the diffusion groove, the No. 2 spring 12 is located in the diffusion groove and sleeved on the buffer column 11, and one end of the No. 2 spring 12 is connected to the boss;

[0032] When the ore falls onto the nylon slide 1, the buffer column 11 first extends out of the telescopic slot at one end to contact the mining machine. As the nylon slide 1 moves downward, the buffer column 11 retracts into the telescopic slot, and the No. 2 spring 12 plays a buffering role. At this time, the buffer block 7 is also driven to retract into the buffer slot due to the friction of the buffer column 11 and the force of the No. 2 spring 12, thereby playing a secondary buffering effect. After the buffer column 11 is completely retracted into the telescopic slot, the buffer block 7 retracts into the buffer slot, thereby playing a secondary buffering role, reducing the wear of the nylon slide 1 and increasing the service life of the nylon slide 1.

[0033] In a specific embodiment, the telescopic slot passes through the buffer block 7, and one end of the buffer column 11 located in the telescopic slot is connected to a No. 3 spring 13, and the end of the No. 3 spring 13 away from the buffer column 11 passes through the telescopic slot and extends into the buffer slot and is connected to the inner wall of the buffer slot; when the buffer column 11 is retracted into the telescopic slot, the No. 3 spring 13 will also play a buffering role, thereby achieving a better buffering effect and increasing the service life of the nylon skateboard 1.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
