Description

Technical Field

[0001] The present invention relates to the field of coal mine safety technology, and in particular to a device for intelligent detection and safe removal of dangerous gangue in coal eyes of a mine. Background Art

[0002] A coal chute is a passage or facility used to transport coal in underground coal mines. Its primary purpose is to transport coal mined from the working face to the pit yard, where it is then hoisted to the surface via the main hoist system. Coal chutes are typically designed as inclined tunnels with a certain slope, allowing the coal to flow down the chute under its own gravity.

[0003] Before entering the coal chute to work, a long crowbar must be used to clean the top of the coal chute to remove any loose stones or dangerous blocks. Only after confirming that there are no problems will other personnel be allowed to enter the chute to work. The operation is rather troublesome and laborious.

[0004] Therefore, in order to solve the above problems, a device for intelligent detection and safe removal of dangerous gangue in coal mines has been developed, which can automatically crush the dangerous floating rocks on the roof and facilitate their removal. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art that workers need to use long crowbars to manually find and clean the floating rocks on the top, which is a cumbersome and laborious operation, the present invention provides an intelligent detection and safe removal device for dangerous gangue in mine coal eyes, which can automatically crush the floating rocks on the top and facilitate their removal.

[0006] The technical solution is: an intelligent detection and safe removal device for dangerous gangue in coal eyes of mines, including a handle, a connecting rod, a mounting head, an automatic cleaning mechanism and a detection mechanism. The left part of the handle is connected to the connecting rod, and the left part of the connecting rod is connected to the mounting head. The mounting head is provided with an automatic cleaning mechanism for removing dangerous floating rocks on the top of the wall, and the automatic cleaning mechanism is provided with a detection mechanism for detecting the looseness of the rock wall.

[0007] Furthermore, the right side of the handle is provided with anti-slip grooves.

[0008] Furthermore, the automatic cleaning mechanism includes a fixing frame, an impactor, a first mounting frame, a switcher, an impact head and an automatic cleaning head. The mounting head is connected to the fixing frame on the left side, the fixing frame is rotatably connected to the impactor on the left side, the telescopic end of the impactor is connected to the first mounting frame, the upper part of the first mounting frame is connected to the switcher, the upper side of the switcher is connected to the impact head, and the lower side of the switcher is connected to the automatic cleaning head. The automatic cleaning head is controlled by the switcher to be located at the top, and the telescopic end of the impactor moves through the first mounting frame to drive the automatic cleaning head to move, so that the pumice blocks on the rock wall are automatically crushed by the automatic cleaning head, thereby facilitating the falling off of the pumice blocks on the rock wall.

[0009] Furthermore, the head cone structure is automatically cleared.

[0010] Furthermore, the detection mechanism includes a second mounting frame, a rotating frame, a sensing head and a torsion spring. The upper part of the impactor is connected to the second mounting frame, and the upper part of the second mounting frame is symmetrically and rotatably connected to the rotating frame. The rotating frames are rotatably connected to sensing heads, and the front and rear sides of the sensing heads are connected to the adjacent rotating frames with torsion springs. The impact head is controlled to be located at the top by a switcher, and under the action of the torsion spring, the sensing head is in close contact with the rock wall. The telescopic end of the impactor moves through the first mounting frame to drive the impact head to knock on the rock wall, and then the vibration of the rock is detected by the sensing head, so that the looseness of the rock in the area can be detected.

[0011] Furthermore, it also includes a manual cleaning mechanism, which includes a manual cleaning head, a first fixed block, a locking piece and a spring. The manual cleaning head is connected to the impactor, and the first fixed blocks are connected to the front and rear sides of the left part of the fixed frame. The first fixed blocks are slidably connected to the locking pieces, and the locking pieces are connected to the adjacent first fixed blocks with springs, so that the impactor is rotated ninety degrees clockwise on the fixed frame. During the rotation, the locking piece is squeezed to slide on the first fixed block, and the spring is stretched by force, so that the impactor is fixed and limited by the locking block under the action of the spring, and then the pumice blocks still attached to the rock wall are removed by the manual cleaning head.

[0012] Furthermore, the right sides of both the front and rear parts of the impactor are arc-shaped structures.

[0013] Furthermore, it also includes a fixing mechanism, which includes a slider and a second fixed block. The slider is slidably connected to the rotating frame, and the slider is connected to the second fixed block. When the sensing head is not used for detection, the rotating frame is rotated, folded and stored on the second mounting frame, and then the slider is pushed to move on the rotating frame, so that the sensing head is fixed and limited by the second fixed block.

[0014] Beneficial effects: 1. The present invention controls the automatic cleaning head to be located at the top through the switch, and the telescopic end of the impactor moves through the first mounting bracket to drive the automatic cleaning head to move, which can automatically crush the floating stones on the top of the wall and facilitate its removal.

[0015] 2. The present invention controls the impact head to be located at the top through a switch, and under the action of a torsion spring, the sensing head is in close contact with the rock wall. The telescopic end of the impactor moves to drive the impact head to knock on the rock wall. The vibration of the rock is detected by the sensing head, which can facilitate the detection of the looseness of the rock in the area.

[0016] 3. The present invention rotates the impactor ninety degrees clockwise on the fixed frame, squeezes the locking piece during the rotation to make it slide on the first fixed block, and fixes the impactor by the locking block under the action of the spring, so as to facilitate the removal of pumice blocks still attached to the rock wall by the manual clearing head.

[0017] 4. The present invention rotates, folds and stores the sensor head on the second mounting frame, and then pushes the slider to drive the second fixed block to move on the rotating frame. The second fixed block fixes and limits the sensor head, so that the sensor head can be easily folded and stored when not in use. BRIEF DESCRIPTION OF THE DRAWINGS
