The vast majority of coal mines in my country are underground coal mines. Ore mining and mining operations carried out underground in coal mines are generally called underground coal mine operations. In the process of underground coal mine operations, in order to save manpower and improve work efficiency, chutes are generally used to transport coal materials.

[0021] 4. When the present invention is used, the arc-shaped support frame and the triangular reinforcement ribs support and strengthen the laid track, thereby improving the overall strength and stability of the laid track. The water receiving box can catch the accidentally leaked copper chloride solution to prevent it from dripping onto the liquid pump or the solution tank, causing the equipment to be dirty.

By moving the liquid pump 503, under the pressurized action of the liquid pump 503, the cupric chloride solution in the solution tank 506 can be pumped out through the liquid pumping tube 516.

[0036] according to Figure 3 and Figure 6-Figure 8 As shown, the outer surface of the solution box 506 is fixedly connected with a liquid inlet pipe 517, the output end of the liquid pump 503 is connected with a connecting pipe 504 through a flange, one end of the connecting pipe 504 is fixedly connected with a U-shaped tube 505, and the outer surfaces of the U-shaped tube 505 near both ends are fixedly connected with multiple nozzles 518, and the two ends of the U-shaped tube 505 successively penetrate the treatment box 501 and the adsorption bed 514 to the inside, and the cupric chloride solution is pumped into the connecting pipe 504 through the liquid pumping pipe 516, and then enters the inside of the U-shaped tube 505, and finally the cupric chloride solution is sprayed out through the multiple nozzles 518 to moisten the activated carbon adsorbent, which can improve the adsorption effect.

[0037] according to Figure 1 , Figure 3 and Figure 6-Figure 7 As shown, a water receiving box 502 is fixedly installed at the bottom of the processing box 501 through an auxiliary rod, and the outer surface of the processing box 501 is installed on the outer surface of one side of the mobile positioning vehicle 201 through bolts.

When the cupric chloride solution accidentally leaks out of the adsorption bed 514 and drips outward, it can fall into the water receiving box 502 to prevent the cupric chloride solution from dripping onto the liquid pump 503 or the solution tank 506, causing the equipment to be dirty.

[0038] according to Figure 1-Figure 4As shown, the control component 4 includes an installation box 401, a warning light 402 is fixedly installed on the front surface of the installation box 401, a control panel 404 is provided on the outer surface of one side of the installation box 401, an infrared absorption sensor 403 is fixedly installed on the outer surface of the other side of the installation box 401, a PLC controller 405 is fixedly installed on the top of the mobile positioning vehicle 201 near one side, a battery 406 is fixedly installed on the top of the mobile positioning vehicle 201 near the PLC controller 405, the bottom of the installation box 401 is installed on the top of the mobile positioning vehicle 201 by screws, and the battery 406 is used to power other devices.

The warning light 402 can emit light to prompt the staff, and the infrared absorption sensor 403 can detect the methane concentration in the air.

[0039] according to Figure 1 and Figure 4 As shown, the protection component 3 includes a multi-stage electric push rod 301, a protection plate 302 is fixedly installed at the bottom end of the multi-stage electric push rod 301, a plurality of springs 306 are fixedly connected to the inner wall of the protection plate 302, one end of the plurality of springs 306 is fixedly connected to a connecting plate 304, a plurality of buffer air bags 305 are fixedly connected to the outer surface of the connecting plate 304, and a pressure sensor 307 is fixedly installed at the center of the inner wall of the protection plate 302. The multi-stage electric push rod 301 can realize the up and down movement of the protection plate 302. When the thrust of the mobile positioning vehicle 201 is too large or the speed is too fast, the buffer air bag 305 plays a buffering role to protect the chute. The mutual force pushes the connecting plate 304 to move toward the inside of the protection plate 302 and squeezes the spring 306. At the same time, an extrusion force is applied to the pressure sensor 307. The pressure sensor 307 transmits the detected pressure signal to the PLC controller 405, and the PLC controller 405 controls the prompt light 402 to light up.

[0040] according to Figure 1 and Figure 4-Figure 5 As shown, fixing rods 303 are fixedly installed on the top of the front and rear surfaces of the protective plate 302, and one end of the two fixing rods 303 is movably inserted into the top of the mobile positioning vehicle 201. The top of the multi-stage electric push rod 301 is fixedly installed on the top surface of the other side inside the mobile positioning vehicle 201, and one end of the two hydraulic rods 206 is movably inserted into the inside of the two L-shaped plates 202. When the protective plate 302 moves up and down, the two fixing rods 303 slide at the same time, so as to improve the stability of the movement of the protective plate 302.

[0041] according to Figure 1 , Figure 3 and Figure 5As shown, a reinforcement bin 7 is provided on the outer surface of the laid track 1, and a plurality of arc-shaped support frames 8 are fixedly installed inside the reinforcement bin 7, and the inner walls of the plurality of arc-shaped support frames 8 are fixedly installed with triangular reinforcement ribs 9, and the bottoms of the plurality of triangular reinforcement ribs 9 are fixedly installed on the bottom surface of the reinforcement bin 7, and two support rods 204 are fixedly installed on the outer surfaces of the two anti-deflection plates 203, and the plurality of support rods 204 are evenly divided into two groups, and one end of the two groups of support rods 204 respectively movably penetrates the two L-shaped plates 202 and the two reinforcement plates 205 to the outer surface, so as to support and strengthen the laid track 1 under the action of the arc-shaped support frames 8 and the triangular reinforcement ribs 9, thereby improving the overall strength and stability of the laid track 1.

[0042] The effect and working principle of the whole mechanism are as follows: when in use, the hydraulic rod 206, the multi-stage electric push rod 301, the pressure sensor 307, the liquid pump 503, the fan 507, the prompt light 402, the infrared absorption sensor 403, the control panel 404, the PLC controller 405 and the battery 406 are electrically connected, and the battery 406 is used to power other devices. The staff can send the operation command to the PLC controller 405 through the operation button on the control panel 404, and start the corresponding device through the PLC controller 405. The outer surface of the mobile positioning vehicle 201 is installed with a push-pull handrail near the processing box 501. The staff puts the chute on the bottom surface of the inside of the mobile positioning vehicle 201, and then uses the control panel to control the chute. The command button on 404 activates the two hydraulic rods 206, pushing the two anti-deflection plates 203 to move relative to each other at the same time, further pushing the chute to move, so that the chute remains in the center position inside the mobile positioning vehicle 201 to prevent deviation, and then starts the multi-stage electric push rod 301 to push the protective plate 302 to move downward, and at the same time, the two fixed rods 303 slide downward to improve the stability of the movement of the protective plate 302. When the protective plate 302 moves, it drives the connecting plate 304 and the buffer airbag 305 to move to one side of the chute to protect the chute to prevent the subsequent push from causing excessive thrust, resulting in collision and wear between the chute and another chute. The staff pushes the mobile positioning vehicle 201 to move by pushing and pulling the handrail, and the two sets of rollers 208 move in the corresponding positioning chute 1 0 to position the mobile positioning vehicle 201 to prevent the mobile positioning vehicle 201 from deflecting during movement. When the chute moves to another chute, the buffer airbag 305 first contacts the other chute. Under the thrust, the buffer airbag 305 is subjected to an extrusion force, pushing the connecting plate 304 to move inside the protective plate 302 and squeezing the spring 306. At the same time, an extrusion force is applied to the pressure sensor 307. The pressure sensor 307 transmits the detected pressure signal to the PLC controller 405 in the form of an electrical signal. The PLC controller 405 controls the prompt light 402 to light up according to the received pressure signal, prompting the staff that the chute is about to be docked and needs to be pushed slowly to prevent collision and wear between the chutes. At this time, the staff The multi-stage electric push rod 301 is started again, the protective plate 302 is pulled to reset, and the connecting plate 304 and the buffer airbag 305 are driven to reset, and then the mobile positioning vehicle 201 is slowly pushed, so that the chute in the mobile positioning vehicle 201 gradually docks with the other chute. At this time, the two chutes are relatively aligned, which is convenient for subsequent installation. Under the action of the protective component 3, the chute is protected to reduce the occurrence of collision and wear. Then, the two chutes are fixed and installed by tightening bolts, and then the two hydraulic rods 206 are started to pull the anti-deflection plate 203 to reset, and finally the mobile positioning vehicle 201 is pulled away, thereby completing the laying and installation of the chute, and then the chute is fixed to the top of the laying track 1 by bolts, so as to strengthen the firmness of the chute laying and installation, and solve the problem of the chute in the laying and installation process.The laying of the chute by manual dragging may cause accidental collision between the chutes, resulting in wear or damage to the chutes, and misalignment, which will affect the installation of the chutes. Under the action of the arc support frame 8 and the triangular reinforcement ribs 9, the laying track 1 is supported and strengthened to improve the overall strength and stability of the laying track 1. The infrared absorption sensor 403 is started to detect the methane concentration in the air. The infrared absorption sensor 403 contains an infrared light source with a specific wavelength and a detector. When the infrared light passes through the gas in the air, the methane molecules in the gas will absorb the infrared light of a specific wavelength. Therefore, when the infrared light passes through the gas in the air and reaches When the light reaches the detector, the detector will measure the change in light intensity. According to the change in light intensity, the concentration of methane can be calculated, and then the detected methane concentration data is transmitted to the PLC controller 405 in the form of an electrical signal. The maximum and minimum working thresholds of the methane concentration are pre-set inside the PLC controller 405. When the methane concentration exceeds the maximum value, the PLC controller 405 will first start the liquid pump 503, and then start the fan 507. Under the pressurized action of the liquid pump 503, the copper chloride solution in the solution tank 506 is pumped into the connecting pipe 504 through the liquid pumping pipe 516, and then enters the U-shaped tube 505, and finally the copper chloride is sprayed out through multiple nozzles 518. The adsorption bed 514 is filled with activated carbon adsorbent. After the nozzle 518 sprays the cupric chloride solution, the cupric chloride solution wraps the outer surface of the activated carbon adsorbent to make it wet. The liquid pump 503 will automatically stop after working for a period of time. Then the fan 507 is started, and the surrounding air is sucked into the suction pipe 509 through the two conical suction hoods 510. The air containing methane gas is transported to the delivery pipe 511 through the fixed pipe 508, and then enters the adsorption bed 514 through the exhaust pipe 513. The methane molecules interact with the surface of the activated carbon through physical and chemical reactions and are adsorbed on the activated carbon. At the same time, the cupric chloride solution on the surface of the activated carbon adsorbent can It reacts chemically with methane to generate methyl chloride. This reaction changes the chemical properties of methane, making it easier to be adsorbed by activated carbon adsorbent. Spraying copper chloride solution can enhance the adsorption capacity of activated carbon for methane, thereby improving the methane removal effect. The treated gas is discharged through multiple air outlets 515, reducing methane gas in the air and improving the safety of the working environment. A water receiving box 502 is installed at the bottom of the treatment box 501. When the copper chloride solution accidentally leaks from the adsorption bed 514 and drips through the air outlet 515, it can fall into the water receiving box 502 to prevent the copper chloride solution from dripping onto the liquid pump 503 or the solution tank 506, causing the equipment to be dirty.
