Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically to a bottom-discharge skip hook positioning wireless detection device. Background Technology

[0002] In a mine shaft hoisting system, the container used to hoist ore is called a skip. The skip is loaded with ore from underground, then hoisted along a straight track to the surface before entering a curved track. Afterward, the gate hook automatically opens, allowing the ore to be poured into the surface ore bin. During the return trip underground, as the skip leaves the curved track and enters the straight track, its gate automatically closes, and the hook engages with the locking ring to lock the gate. If the gate fails to lock reliably, ore will spill to the bottom of the shaft when the skip is reloaded, potentially injuring personnel and equipment. Therefore, the hook position must be checked during the skip's descent.

[0003] A bottom-discharge skip hook detection device (CN201820581595.8) has been developed to automatically detect skip hooks, which greatly reduces the labor intensity of personnel and improves the hoisting efficiency of ore. However, it has shortcomings in disassembly and assembly, poor protection effect of the detection switch, unstable fixing, and poor detection and usage effects. Therefore, a bottom-discharge skip hook positioning wireless detection device is needed to solve the above problems. Utility Model Content

A hook drive wheel 2 is installed on the side, and a skip hook 3 is installed on one side of the hook drive wheel 2. A hook groove 5 is hooked and installed on one side of the skip hook 3, and a threaded mounting groove 13 is opened on the other side edge of the skip hook 3. A threaded mounting block 14 is inserted and installed on the inner wall of the threaded mounting groove 13, and a hook head detection auxiliary flat iron 4 is fixedly connected to the upper end of the threaded mounting block 14. The outer wall of the hook head detection auxiliary flat iron 4 is made of rubber, and the hook head detection auxiliary flat iron 4 is screwed and spliced ​​with the skip hook 3 through the threaded mounting groove 13 and the threaded mounting block 14. This allows the hook head detection auxiliary flat iron 4 to be quickly disassembled and installed, and is easy to replace.

[0022] The hook detection auxiliary flat iron 4 and the detection switch 12 are arranged vertically, and the detection switch 12 is wirelessly connected to the unloading operation table PLC 8 through the signal receiver 7 and the signal transmitter 9. This allows the hook detection auxiliary flat iron 4 to make more efficient contact with the detection switch 12, resulting in better detection effect. The detection switch 12 is distributed on one side of the hook detection auxiliary flat iron 4, and the detection switch 12 is fitted with a detection switch mounting bracket 11. The detection switch mounting bracket 11 and the detection switch 12 are arranged in a wrapping distribution, and the detection switch mounting bracket 11 has a trapezoidal structure. This allows the detection switch mounting bracket 11 to wrap and protect the detection switch 12 and to guide the falling rocks.

[0023] A mounting plate 19 is installed on the upper end of the detection switch mounting bracket 11, and fixing bolts 20 are inserted and installed through both sides of the inner wall of the mounting plate 19. A support spring 18 is vertically fixed to the upper end of the mounting plate 19, and a detection switch guard plate 17 is fixedly connected to the upper end of the support spring 18. The detection switch guard plate 17 is elastically connected to the detection switch mounting bracket 11 through the support spring 18, and the detection switch guard plate 17 is bolted to the detection switch mounting bracket 11 through the mounting plate 19 and fixing bolts 20.

[0025] Working principle: When using this bottom-discharge skip hook positioning wireless detection device, the device is first assembled and fixed by welding through sleeve 15 and welding block 16. When the skip hook 3 moves to the hook groove 5, the hook head detection auxiliary flat iron 4 contacts the detection switch 12, and the signal is transmitted to the unloading operation table PLC 8 through the signal receiver 7 and signal transmitter 9. When the detection switch 12 is hit by falling rocks, it can be elastically supported by the detection switch guard plate 17 and support spring 18. When the input and output wires 10 of the detection switch are hit, they can be protected by the wire conduit 6 and protective pad 21. When the detection switch guard plate 17 is damaged, it can be quickly disassembled and replaced by mounting plate 19, fixing bolts 20 and detection switch mounting bracket 11. This is the usage process of this bottom-discharge skip hook positioning wireless detection device.
