[0026] The disassembly device of the present invention can quickly disassemble the suspension mechanism, and there is no need for personnel to climb to the top plate of the tunnel. They only need to stand on the ground of the tunnel and use the disassembly column to apply an upward thrust to the lifting ring fixing anchor. When the lifting ring fixing anchor is removed, the support rod, the left disassembly rod, and the right disassembly rod are used to clamp the horizontal force rod and the vertical load-bearing rod to prevent the suspension mechanism from falling, which greatly improves the disassembly efficiency while reducing the risk of disassembly injury.

[0053] Then fix the lifting eye fixing anchor 10 to the lower end of the anchor cable 24 that has been driven into the tunnel roof, then extend the front end of the front probe beam into the accommodating area of ​​the suspension mechanism on the front side of the suspension unit, and extend the rear end of the front probe beam into the accommodating area of ​​the suspension mechanism on the rear side of the suspension unit, so that the front probe beam is carried and pulled.

Then the hand-held rod 16 is moved upward, so that the lower end of the anchor cable 24 extends into the disassembly hole of the disassembly column 18, and the upper end of the disassembly column 18 touches the lower end of the lifting ring fixing anchor 10. At this time, the disassembly column 18 is pushed upward with force through the hand-held rod 16, forcing the lifting ring fixing anchor 10 to release the anchor cable 24 and move downward quickly until the lifting ring fixing anchor 10 is detached from the anchor cable 24.

[0056] Example 1

[0057] Due to the particularity of the surrounding rock of the coal mine roof, the anchor net support of some tunnels in the north wing 2# return air lane of a certain mine cannot meet the requirements, and the full section needs to be supported by anchor cables. Since the temporary support used by the mine is a front exploration beam with a single unit, the current front exploration beam lifting ring can only be used on the anchor rod, and cannot be used for full anchor cable support. Therefore, the original front exploration beam lifting ring cannot meet the support needs, resulting in the front exploration beam cannot be used normally, and the front cannot be well supported after blasting or excavation, resulting in the roof falling gangue and injuring people when personnel support the single unit.

[0058] We now use waste drill rods, locks, and waste steel pipes to process suspension systems, and use waste materials to process and disassemble equipment for suspension mechanisms.

[0059] After a long period of use, the problem of the front exploration beam not being able to be used normally after blasting or excavation during pure anchor support in the north wing No. 2 return air channel has been solved, as well as the problem of danger for personnel constructing single units under the exposed roof, which has greatly improved the safety of employees' operations and created benefits for the safe development of the mine.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
