Description

Technical Field

[0001] This invention relates to the field of coal mine engineering technology, specifically to a chute laying device for underground coal mine operations. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas, generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, tunnels are typically dug underground to extract the coal; this is called an underground coal mine. The vast majority of coal mines in my country are underground mines. The ore mining and mining operations carried out underground are generally called underground coal mine operations. During underground coal mine operations, to save manpower and improve work efficiency, chutes are generally used to transport coal ore. The collected coal is placed in the chute, and then the chute itself, or a conveyor scraper, automatically transports the coal from underground to the mine entrance or other designated locations.

[0003] In existing technologies, during the installation of chutes, workers usually drag the chutes to the required location, then connect and fix them together. However, chutes have a certain weight, and dragging them manually can cause accidental collisions between them, resulting in wear or damage. The positions of the chutes may also become misaligned, and manual adjustment is not accurate enough, affecting the stability of the chute installation.

[0004] Therefore, we propose a chute laying device for underground coal mine operations to solve the problems mentioned in the background art. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When using this invention, the chute is placed inside the mobile positioning vehicle. The two hydraulic rods are activated by the command button on the control panel to push the two anti-deviation plates to move relative to each other, pushing the chute to the middle position to prevent deviation. Then, the mobile positioning vehicle is moved to the installation location. Two sets of rollers slide in the positioning chute to position the mobile positioning vehicle and prevent it from deviating. After the two chutes are connected, they are fixed in place by fastening bolts. Then, the two hydraulic rods are activated again to pull the anti-deviation plates back to their original position. Finally, the mobile positioning vehicle is pulled away, thus completing the laying and installation of the chute.

[0019] 2. When using this invention, the multi-stage electric actuator is activated to push the protective plate downwards, causing the connecting plate and buffer airbag to move to one side of the chute to protect the chute. When the thrust is too great, the buffer airbag acts as a buffer. At the same time, under the thrust, the connecting plate is pushed to move, applying pressure to the pressure sensor. The pressure sensor sends a pressure signal to the PLC controller, which controls the indicator light to light up, prompting the operator that the thrust is too great and needs to be pushed slowly. The multi-stage electric actuator is activated again to pull the protective plate back to its original position. Then, the moving positioning vehicle is slowly pushed to dock. Under the action of the protective components, the chute is protected, reducing the occurrence of collision and wear.

[0020] 3. When using this invention, the infrared absorption sensor is activated to detect the methane concentration and transmits the data to the PLC controller. When the methane concentration exceeds the maximum value, the PLC controller will sequentially start the liquid pump and the fan. The copper chloride solution inside the solution tank is pumped through the liquid pumping pipe to the connecting pipe and the U-shaped pipe. Then, the copper chloride solution is sprayed out through the nozzle to wet the activated carbon adsorbent, which can improve the adsorption capacity for methane. After the fan is started, the air is sequentially drawn into the suction pipe and the fixed pipe through two conical suction hoods. Then, it enters the adsorption bed through the delivery pipe and the exhaust pipe and is efficiently adsorbed on the activated carbon, thereby improving the methane removal effect.

[0021] 4. When this invention is used, the track is supported and strengthened by the arc-shaped support frame and the triangular reinforcing ribs, which improves the overall strength and stability of the track. The water receiving box can catch any accidental leakage of copper chloride solution, preventing it from dripping onto the pump or solution tank and causing the equipment to become dirty.

Rollers 208 are movably fitted on the outer surface of each of the multiple reinforcing rods 207. The multiple rollers 208 are divided into two groups. Two positioning grooves 10 are opened on the bottom surface inside the track 1. The outer surfaces of the two groups of rollers 208 are movably embedded in the two positioning grooves 10 respectively.

[0033] At the same time, according to Figures 6-8 As shown, the processing component 5 includes a processing box 501. A reinforcing plate 512 is fixedly installed on the inner wall of the processing box 501 near the top. A fan 507 is fixedly installed on the top of the reinforcing plate 512. A fixed pipe 508 is fixedly connected to the input end of the fan 507. A suction pipe 509 is fixedly connected to one end of the fixed pipe 508. Conical suction hoods 510 are fixedly connected to both ends of the suction pipe 509. A conveying pipe 511 is fixedly connected to the output end of the fan 507. Multiple exhaust pipes 513 are fixedly connected to the outer surface of the conveying pipe 511. By starting the fan 507, the surrounding air is drawn into the suction pipe 509 by the two conical suction hoods 510. The air containing methane gas is conveyed into the conveying pipe 511 through the fixed pipe 508, and then enters the adsorption bed 514 through the exhaust pipes 513.

[0034] according to Figure 3 and Figures 6-8 As shown, an adsorption bed 514 is fixedly installed on the inner wall of the treatment box 501 near the bottom. The bottom ends of multiple exhaust pipes 513 extend into the interior of the adsorption bed 514. Multiple air outlets 515 are opened at the bottom of the treatment box 501. A fixing plate 6 is fixedly installed on the outer surface of the moving positioning vehicle 201 near the bottom. Methane gas can be discharged into the adsorption bed 514 through the exhaust pipes 513, and fully contacted with the activated carbon adsorbent therein to adsorb methane. The treated gas can be discharged to the outside through the air outlets 515.

[0035] according to Figure 3 and Figures 6-7As shown, a liquid pump 503 is mounted on the top of the fixed plate 6 near the front surface by screws. The input end of the liquid pump 503 is connected to a liquid extraction pipe 516 via a flange. A solution tank 506 is fixedly mounted on the top of the fixed plate 6 near the rear surface. One end of the liquid extraction pipe 516 is fixedly inserted into the interior of the solution tank 506. By moving the liquid pump 503, under the pressure of the liquid pump 503, the copper chloride solution inside the solution tank 506 can be extracted through the liquid extraction pipe 516.

[0036] according to Figure 3 and Figures 6-8 As shown, an inlet pipe 517 is fixedly connected to the outer surface of the solution tank 506. The output end of the pump 503 is connected to a connecting pipe 504 via a flange. A U-shaped pipe 505 is fixedly connected to one end of the connecting pipe 504. Multiple nozzles 518 are fixedly connected to the outer surface of the U-shaped pipe 505 near both ends. The two ends of the U-shaped pipe 505 pass through the treatment tank 501 and the adsorption bed 514 to the inside. The copper chloride solution is pumped into the connecting pipe 504 through the pumping pipe 516, and then enters the U-shaped pipe 505. Finally, the copper chloride solution is sprayed out through the multiple nozzles 518 to wet the activated carbon adsorbent, which can improve the adsorption effect.

[0037] according to Figure 1 , Figure 3 and Figures 6-7 As shown, a water receiving box 502 is fixedly installed at the bottom of the treatment box 501 by an auxiliary rod. The outer surface of the treatment box 501 is bolted to the outer surface of one side of the mobile positioning vehicle 201. The two ends of the suction pipe 509 are fixedly inserted through the front and rear surfaces of the treatment box 501, respectively. One end of the conveying pipe 511 is fixedly installed on the rear wall inside the treatment box 501. When the copper chloride solution accidentally leaks out of the adsorption bed 514 and drips outward, it can fall into the water receiving box 502, preventing the copper chloride solution from dripping onto the pump 503 or the solution tank 506 and causing the equipment to become dirty.

[0038] according to Figures 1-4As shown, the control component 4 includes a mounting box 401. An indicator light 402 is fixedly mounted on the front surface of the mounting box 401. A control panel 404 is provided on one outer surface of the mounting box 401. An infrared absorption sensor 403 is fixedly mounted on the other outer surface of the mounting box 401. A PLC controller 405 is fixedly mounted on the top of the mobile positioning vehicle 201 near one side. A battery 406 is fixedly mounted on the top of the mobile positioning vehicle 201 near the PLC controller 405. The bottom of the mounting box 401 is mounted on the top of the mobile positioning vehicle 201 with screws. The battery 406 supplies power to other devices. The operator can send operation commands to the PLC controller 405 through the operation buttons on the control panel 404. The PLC controller 405 starts the corresponding device, the indicator light 402 can light up to remind the operator, 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 protective component 3 includes a multi-stage electric actuator 301. A protective plate 302 is fixedly installed at the bottom of the multi-stage electric actuator 301. Multiple springs 306 are fixedly connected to the inner wall of the protective plate 302. A connecting plate 304 is fixedly connected to one end of each spring 306. Multiple buffer airbags 305 are fixedly connected to the outer surface of the connecting plate 304. A pressure sensor 307 is fixedly installed at the center of the inner wall of the protective plate 302. The multi-stage electric actuator 301 can realize the up and down movement of the protective plate 302. When the moving positioning vehicle 201 has too much thrust or too fast speed, the buffer airbags 305 play a buffering role and protect the chute. The interaction force pushes the connecting plate 304 to move into the protective plate 302 and squeezes the springs 306. At the same time, it applies pressure to the pressure sensor 307. The pressure sensor 307 sends the detected pressure signal to the PLC controller 405, and the PLC controller 405 controls the indicator light 402 to light up.

[0040] according to Figure 1 and Figures 4-5 As shown, a fixing rod 303 is fixedly installed on the top of the protective plate 302 near the front and rear surfaces. One end of each fixing rod 303 extends movably through to the top of the mobile positioning vehicle 201. The top end of the multi-stage electric push rod 301 is fixedly installed inside the mobile positioning vehicle 201 near the top surface on the other side. One end of each of the two hydraulic rods 206 extends movably through to the interior of the two L-shaped plates 202. When the protective plate 302 moves up and down, the two fixing rods 303 slide simultaneously, which helps to improve the stability of the movement of the protective plate 302.

[0041] according to Figure 1 , Figure 3 and Figure 5As shown, a reinforcing chamber 7 is provided on the outer surface of the track 1. Multiple arc-shaped support frames 8 are fixedly installed inside the reinforcing chamber 7. Triangular reinforcing ribs 9 are fixedly installed on the inner walls of the multiple arc-shaped support frames 8. The bottom of the multiple triangular reinforcing ribs 9 is fixedly installed on the bottom surface inside the reinforcing chamber 7. Two support rods 204 are fixedly installed on the outer surface of the two anti-deviation plates 203. The multiple support rods 204 are divided into two groups. One end of the two groups of support rods 204 respectively movably passes through the two L-shaped plates 202 and the two reinforcing plates 205 to the outer surface, so as to facilitate the support and reinforcement of the track 1 under the action of the arc-shaped support frames 8 and the triangular reinforcing ribs 9, thereby improving the overall strength and stability of the track 1.

[0042] The overall mechanism and its working principle are as follows: When in use, the hydraulic rod 206, multi-stage electric actuator 301, pressure sensor 307, liquid pump 503, fan 507, indicator light 402, infrared absorption sensor 403, control panel 404, PLC controller 405, and battery 406 are electrically connected. The battery 406 supplies power to other equipment. Operators can send operation commands to the PLC controller 405 via the operation buttons on the control panel 404, which then starts the corresponding equipment. A push-pull handle is installed on the outer surface of the mobile positioning vehicle 201 near the processing box 501. Operators place the chute on the bottom of the mobile positioning vehicle 201 and then use the control panel... The command button on 404 activates two hydraulic rods 206, pushing two anti-deviation plates 203 to move relative to each other simultaneously, further pushing the chute to move so that the chute remains centered inside the moving positioning vehicle 201 to prevent deviation. Then, the multi-stage electric actuator 301 is activated to push the protective plate 302 downward, while the two fixed rods 303 slide downward to improve the stability of the protective plate 302's movement. As the protective plate 302 moves, it drives the connecting plate 304 and the buffer airbag 305 to one side of the chute to protect it and prevent excessive thrust during subsequent pushing, which could cause the chute to collide with another chute and cause wear. The operator pushes and pulls the handle to move the moving positioning vehicle 201, and the two sets of rollers 208 move in the corresponding positioning chute 1. The chute slides in position 0 to position the mobile positioning vehicle 201 and prevent it from shifting 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 compressed, pushing the connecting plate 304 into the protective plate 302 and compressing the spring 306. At the same time, it applies pressure to the pressure sensor 307. The pressure sensor 307 transmits the detected pressure signal to the PLC controller 405 via an electrical signal. The PLC controller 405 controls the indicator light 402 to light up based on the received pressure signal, indicating to the staff that the chute is about to be connected and needs to be pushed slowly to prevent collision and wear between the chute and the other chute. At this time, the staff can then... The multi-stage electric actuator 301 is activated, pulling the protective plate 302 to reset, which in turn resets the connecting plate 304 and the buffer airbag 305. Then, the mobile positioning vehicle 201 is slowly pushed, gradually aligning the chute within it with another chute. At this point, the two chutes are aligned, facilitating subsequent installation. The protective component 3 protects the chute, reducing collision and wear. The two chutes are then secured with bolts. Next, the two hydraulic rods 206 are activated, pulling the anti-deviation plate 203 to reset. Finally, the mobile positioning vehicle 201 is pulled away, completing the chute laying and installation. Bolts are then used to fix the chute to the top of the laying track 1, strengthening the chute's stability and resolving issues encountered during installation.Manually dragging the chutes during installation can lead to accidental collisions, causing wear or damage, and misalignment, affecting installation. The curved support frame 8 and triangular reinforcing ribs 9 strengthen the track 1, improving its overall strength and stability. The infrared absorption sensor 403 detects the methane concentration in the air. This sensor contains a specific wavelength infrared light source and a detector. When infrared light passes through the air, methane molecules absorb the specific wavelength. When the light reaches the detector, the detector measures the change in light intensity. Based on the change in light intensity, the concentration of methane can be calculated. Then, the detected methane concentration data is transmitted to the PLC controller 405 as an electrical signal. The PLC controller 405 has a pre-set maximum and minimum working threshold for methane concentration. When the methane concentration exceeds the maximum value, the PLC controller 405 will first start the pump 503, then start the fan 507. Under the pressure of the pump 503, the copper chloride solution in the solution tank 506 is pumped through the pumping pipe 516 to the connecting pipe 504, then into the U-shaped tube 505, and finally sprayed out through multiple nozzles 518. The adsorption bed 514 is filled with activated carbon adsorbent. After the nozzle 518 sprays out the copper chloride solution, it coats the surface of the activated carbon adsorbent, wetting it. The pump 503 automatically stops after operating for a period of time. Then, the fan 507 starts, drawing surrounding air into the suction pipe 509 through two conical suction hoods 510. The air containing methane gas is then transported to the delivery pipe 511 through the fixed pipe 508, and subsequently enters the adsorption bed 514 through the exhaust pipe 513. Methane molecules interact with the activated carbon surface through physical and chemical processes, becoming adsorbed onto the activated carbon. Simultaneously, the copper chloride solution on the surface of the activated carbon adsorbent can... A chemical reaction occurs with methane to produce methyl chloride. This reaction changes the chemical properties of methane, making it more easily adsorbed by activated carbon adsorbents. Spraying copper chloride solution enhances the adsorption capacity of activated carbon for methane, thereby improving the methane removal effect. The treated gas is discharged through multiple vents 515, reducing the amount of methane in the air and improving the safety of the working environment. A water collection box 502 is installed at the bottom of the treatment tank 501. When copper chloride solution accidentally leaks from the adsorption bed 514 and drips through the vents 515, it can fall into the water collection box 502, preventing the copper chloride solution from dripping onto the pump 503 or the solution tank 506 and causing the equipment to become dirty.

[0043] Among them, the hydraulic rod 206, the multi-stage electric actuator 301, the pressure sensor 307, the liquid pump 503, the fan 507, the indicator light 402, the infrared absorption sensor 403, the control panel 404, the PLC controller 405, and the battery 406 are all existing technologies, and their components and operating principles are all publicly available technologies, so they will not be explained in detail here.
