[0002] At present, in coal mining, especially in mining of rock burst mines, pressure relief work is particularly important, especially the pressure relief of the bottom plate, which is mainly carried out in three ways: drilling pressure relief, blasting pressure relief and trenching pressure relief.

[0003] In the existing patent, a continuous top cutting device of a chain arm saw for mining includes a crawler walking mechanism, a fixed seat, a chain arm saw rotatably connected to the fixed seat, a cutting chain installed on the chain arm saw, and a power head for driving the cutting chain to rotate at high speed on the chain arm saw. The cutting chain is driven by the power head to cut the mine tunnel.

[0004] Regarding the above-mentioned existing patents, during the initial cutting, the cutting chain needs to be aligned with the cutting position, and then the chain arm saw needs to be inserted into the coal mine with the help of the crawler walking mechanism. Due to the uneven ground or the shaking caused by cutting, the chain arm will collide with the coal mine, affecting the cutting effect of the coal mine, which urgently needs to be improved. Summary of the Invention

[0005] In order to improve the stability of chain arm saws in cutting coal mines, ensure the cutting effect of chain arm saws, and improve the convenience of coal mining, the present application provides a chain sawing equipment for mining.

[0006] The present application provides a mining chain sawing equipment adopting the following technical solutions:

[0007] It includes a crawler walking mechanism, an electrical part, a hydraulic part and a sliding mechanism. The sliding structure includes a sliding seat that is slidingly connected to the crawler walking mechanism. A chain saw plate is rotatably connected to the sliding seat. A chain saw bar is installed on the chain saw plate. A driving head for driving the chain saw bar to rotate is provided on the chain saw plate. A first driving member for driving the chain saw plate to rotate is provided on the sliding seat. A second driving member for driving the sliding seat to slide on the crawler walking mechanism is provided on the sliding seat.

[0008] By adopting the above technical solution, during operation, the electrical unit controls the electrical system of the entire device, while the hydraulic unit controls the hydraulic drive of the device. The chain saw blade is stored on the crawler track by driving the sliding seat. When cutting is required, the chain saw blade is activated, and the sliding seat is then controlled by the second driving member to move, thereby causing the chain saw blade to cut the coal, achieving stable coal cutting. The sliding seat slides on the crawler track, allowing the chain saw blade to better cut the coal, improving the stability of the chain arm saw in coal cutting, ensuring the cutting effect of the chain arm saw, and increasing the convenience of coal mining.

[0009] Preferably, fixed frames are provided on both sides of the crawler walking mechanism, a bucket is rotatably provided on the fixed frame, and a third driving member for driving the bucket to rotate is provided on the fixed frame.

[0010] By adopting the above technical solution and using two buckets, on the one hand, the debris on both sides of the crawler traveling mechanism can be cleaned up, so that the crawler traveling mechanism can move more smoothly, and an area suitable for the crawler traveling mechanism to stay and work can be cleaned up, thereby improving the stability of the crawler traveling mechanism during operation; on the other hand, the two sides of the crawler traveling mechanism can be supported, so that the force points of the entire equipment can be applied to the two buckets, which can better balance the pressure acting on the chain saw plate during cutting, reduce the tilting of the equipment, and improve the stability of the mining chain saw cutting equipment.

A water tank is provided on the crawler walking mechanism, and a spray pipe is provided between the water tank and the plurality of nozzles, and the spray pipe is provided with a spray pump in the water tank.

[0012] By adopting the above technical solution, a nozzle is used to spray water on the chain saw blade, thereby reducing the temperature of the chain saw blade, enabling the chain saw blade to better cut coal, reducing dust generation, improving the comfort of the working environment, and improving the effect of coal cutting.

[0013] Preferably, the electrical part includes a control box installed on the crawler walking mechanism and a display screen and an operation box on the control box. The control box is arranged at one end of the crawler walking mechanism away from the chain saw plate. The hydraulic part includes an oil tank. The oil tank is equipped with an oil return pipe, an oil suction pipe, an oil pump, a control valve and a motor. The oil tank is arranged on the side of the control box close to the chain saw plate.

[0014] By adopting the above technical solution, the control box and the oil tank are fixed to the end of the crawler traveling mechanism away from the chain saw plate. When the chain saw plate is under pressure, the weight of the control box and the oil tank can balance the force of the chain saw plate, thereby reducing the shaking of the crawler traveling mechanism and improving the stability of the chain saw cutting equipment.

[0015] Preferably, a personnel approach controller is provided on the side of the crawler walking mechanism, and a personnel approach sensor is provided on the personnel approach controller. The personnel approach controller is used to control the switch of the control box. When a person approaches the machine, the personnel approach controller controls the control box to be closed.

[0016] By adopting the above technical solution, when in use, the staff first directly turns on the switch of the control box, so that the chain saw cutting equipment can work normally. When the machine is working normally, the staff stays away from the machine. When there is a problem with the cutting or adjustment is required, the staff approaches. At this time, the personnel proximity sensor senses the arrival of the personnel, and the control box is turned off through the personnel proximity controller, so that the machine can stop working, which is convenient for the staff to operate safely.

[0017] Preferably, the chainsaw plate includes a chainsaw head and a chainsaw tail, and a plurality of chainsaw bodies are arranged between the chainsaw head and the chainsaw tail. The chainsaw bodies are used to increase the length of the chainsaw plate, and an auxiliary wheel is rotatably connected to the chainsaw tail. The chain saw blade is rotatably connected to the auxiliary wheel, and the drive head is fixed to the chainsaw head.

[0018] By adopting the above technical solution, when in use, the chain saw plate is assembled by a chain saw head, a chain saw tail and several chain saw bodies. By controlling the number of chain saw bodies, the length of the chain saw plate can be controlled. The adjustable length design can better increase the cutting depth to meet the construction needs of deep mining or special tunnels.

[0019] Preferably, a plurality of hinge seats are provided at one end of the chain saw head close to the chain saw tail, a plurality of hinge joints are provided at one end of the chain saw tail close to the chain saw head, hinge joints and hinge seats are provided at both ends of the chain saw body, and the hinge joints are rotatably connected with the hinge seats; a plurality of first plug rods are telescopically provided on the chain saw head, the first plug rods are arranged along the length direction of the chain saw plate, a first socket which is plugged into and matched with the first plug rod is provided on one side of the chain saw body close to the chain saw head, and a fourth driving member for driving the plurality of first plug rods to slide is provided on the chain saw head; a second plug rod is slidably connected to the chain saw body, and a second socket which is plugged into and matched with the second plug rod is provided on the chain saw tail, the first plug rod passes through the first socket and pushes the second plug rod to be plugged into the second socket.

[0020] By adopting the above technical solution, the chain saw body is hingedly connected to the chain saw head, and the chain saw tail is rotatably connected to the chain saw body, so that the chain saw tail and the chain saw body can be installed more conveniently, thereby improving the convenience of assembling the chain saw plate. In addition, the hinged connection method can greatly reduce the length of the chain saw plate after contraction, thereby improving the convenience of using the chain saw cutting equipment. In combination with the first insertion rod and the second insertion rod, the chain saw body and the chain saw tail can be restricted, thereby improving the firmness of the chain saw body and the chain saw tail.

[0021] Preferably, a sliding spray seat is slidingly connected to the chain saw plate, and the sliding spray seat is slidingly arranged along the length direction of the chain saw plate. A support tube is provided on the sliding spray seat, and the end of the support tube away from the sliding spray seat is rotatably connected to a rotating wheel. A plurality of spray nozzles are provided on the side wall of the support tube, and the spray nozzles are connected to the water tank. The liquids sprayed from the plurality of spray nozzles constitute a protective cover, and the protective cover is used to reduce dust diffusion.

[0022] By adopting the above technical solution, a protective cover is formed by liquid ejected from multiple nozzles, thereby reducing the diffusion of dust, reducing the diffusion of dust in the tunnel, and improving the comfort of the working environment. When the chain saw plate is inserted into the coal mine, the rotating wheel abuts against the coal mine, which can better limit the diffusion of dust. When the chain saw plate rotates, the rotating wheel can make the chain saw plate rotate more conveniently.

[0023] Preferably, the chain saw plate is provided with a spray slide cavity along its length direction, the sliding spray seat is provided with a spray slider that slides with the spray slide cavity, and extrusion strips are provided on both sides of the spray slide cavity, and the extrusion strips abut against the spray slider to limit the movement of the spray slider.

[0024] By adopting the above technical solution, the sliding nozzle seat can be limited by using the injection slider and the extrusion strip, thereby improving the stability of the sliding nozzle.

[0025] Preferably, a pressure sensor is provided at the bottom of the bucket, and the pressure sensor is electrically connected to a control valve. When the pressure of the pressure sensor increases, the control valve reduces the driving speed of the first driving member.

[0026] By adopting the above technical solution, when the mine is cutting, due to the deviation in the hardness of the internal coal and rock, when the first driving member controls the rotation of the chain saw plate, it is easy for the chain saw plate to rotate at a fast speed, causing the equipment to be subjected to greater pressure, which not only affects the cutting effect of the coal mine, but also reduces the cutting stability; the pressure sensor can timely detect the pressure change, and when the pressure change value reaches a certain value, the speed of the first driving member is reduced to improve the stability of the equipment.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. During operation, the electrical unit controls the electrical system of the entire equipment, while the hydraulic unit controls the hydraulic drive. The chain saw blade is stored on the crawler track by driving the sliding seat. When cutting is required, the chain saw blade is activated, and the sliding seat is controlled by the second drive unit to move, thereby enabling the chain saw blade to cut the coal, achieving stable coal cutting. The sliding seat slides on the crawler track, allowing the chain saw blade to better cut the coal, improving the stability of the chain arm saw in cutting coal, ensuring the cutting effect of the chain arm saw, and increasing the convenience of coal mining.

[0029] 2. Using two buckets, on the one hand, can clean up the debris on both sides of the crawler traveling mechanism, making the crawler traveling mechanism move more smoothly, and can also clear out the area suitable for the crawler traveling mechanism to stop and work, thereby improving the stability of the crawler traveling mechanism during operation; on the other hand, it can support both sides of the crawler traveling mechanism, so that the force points of the entire equipment can be applied to the two buckets, which can better balance the pressure acting on the chain saw plate during cutting, reduce equipment tilting, and improve the stability of the mining chain saw cutting equipment;

[0030] 3. When in use, the chain saw plate is assembled by a chain saw head, a chain saw tail and several chain saw bodies.

The adjustable length design can better increase the cutting depth to meet the construction needs of deep mining or special tunnels; the chain saw body is hingedly connected to the chain saw head and the chain saw tail is rotatably connected to the chain saw body, so that the chain saw tail and the chain saw body can be installed more conveniently, thereby improving the convenience of assembling the chain saw plate. In addition, the hinged connection method can greatly reduce the length of the chain saw plate after contraction, thereby improving the convenience of using the chain saw cutting equipment. The first plug rod and the second plug rod can be used to limit the chain saw body and the chain saw tail, thereby improving the firmness of the chain saw body and the chain saw tail.

[0040] The following is combined with Figure 1 - Figure 8 This application is described in further detail.

[0041] The embodiment of the present application discloses a chain sawing device for mining.

[0042] Example 1

[0043] Reference Figure 1A mining chain sawing device includes a crawler track mechanism 1, an electrical unit, a hydraulic unit, and a sliding structure. The sliding structure includes a sliding seat 9 that is slidably connected to the crawler track mechanism 1. The sliding seat 9 is rotatably connected to a chain saw plate 6, on which a chain saw blade 14 is mounted. The chain saw plate 6 is mounted with a drive head 8 for driving the chain saw blade 14 to rotate. The drive head 8 is a sprocket motor. The sprocket motor rotates the chain saw blade 14, thereby reducing the space required. A first drive member 10 for driving the chain saw plate 6 to rotate is fixed to the sliding seat 9. The first drive member 10 is a first drive cylinder. A second drive member 32 is fixed to the sliding seat 9 for driving the sliding seat 9 to slide on the crawler track mechanism 1. The second drive member 32 is a second drive motor. The second drive motor is rotatably connected to a second gear. The crawler track mechanism 1 is provided with a second rack that meshes with the second gear. The second gear and the second rack cooperate to enable the sliding seat 9 to slide more stably. The sliding seat 9 slides on the crawler walking mechanism 1, so that the chain saw bar 14 can better cut the coal mine, improve the stability of the chain arm saw in cutting the coal mine, ensure the cutting effect of the chain saw plate 6, and improve the convenience of coal mining.

[0044] A fixing frame 17 is fixed on both sides of the crawler traveling mechanism 1, and a bucket 5 is rotatably connected to the fixing frame 17. A third driving member 16 for driving the bucket 5 to rotate is fixed on the fixing frame 17. The third driving member 16 is a third driving cylinder. The bucket 5 can be driven to fall through the third driving cylinder, which can not only support the crawler traveling mechanism 1, but also clean up debris during the movement of the crawler traveling mechanism 1.

[0045] A spray rack 19 is fixed on the chain saw blade 14, and a plurality of nozzles 18 facing the chain saw blade 14 are fixed on the spray rack 19. A water tank 15 is fixed on the crawler walking mechanism 1. A spray pipe is connected between the water tank 15 and the plurality of nozzles 18. A spray pump is installed in the spray pipe in the water tank 15. Water can be continuously sprayed toward the chain saw blade 14 through the spray pump, thereby reducing the temperature of the chain saw blade 14 and improving the cutting effect of the coal mine.

[0046] The electrical system includes a control box 11 mounted on the crawler mechanism 1, along with a display and an operating box. The control box 11 is fixed to the end of the crawler mechanism 1 away from the chain saw plate 6. The crawler mechanism 1 comprises a track chain 2, a travel motor 4, and a track frame 3. The travel motor 4 controls the rotation of the track chain 2, ensuring more stable movement of the crawler mechanism 1. The operating box is equipped with switches for controlling the rotation of the travel motor 4 and the sprocket motor, ensuring convenient operation. The hydraulic system includes a fuel tank 7, equipped with a return oil pipe, a suction oil pipe, an oil pump, a control valve, and an electric motor. This hydraulic system controls the normal operation of the first drive element 10 and the second drive element 32. The fuel tank 7 is fixed to the side of the control box 11 near the chain saw plate 6. When the chain saw plate 6 is subjected to pressure, the weight of the control box 11 and the fuel tank 7 balances the force applied by the chain saw plate 6, reducing any shaking of the crawler mechanism 1 and improving the stability of the chain sawing equipment.

[0047] A personnel approach controller 12 is fixed to the side wall of the crawler walking mechanism 1, and a personnel approach sensor 13 is fixed on the personnel approach controller 12. The personnel approach controller 12 is used to control the switch of the control box 11. When a person approaches the machine, the personnel approach controller 12 operates the control box 11 to turn off the electricity, calmly stopping the equipment from working and allowing the staff to operate safely.

[0048] The implementation principle of a mining chain sawing device in an embodiment of the present application is as follows: when working, the tunnel is cleaned by using a bucket 5, and then the crawler walking mechanism 1 is supported by two buckets 5, so that the gravity of the entire equipment can be applied to the two buckets 5, and then the sliding seat 9 is used to push the chain saw blade 14 to cut the coal mine, so that the coal mine can be cut more stably, the stability of the equipment in cutting the coal mine is improved, the cutting effect of the equipment is ensured, and the convenience of coal mining is improved.

[0049] Example 2

[0050] Reference Figure 5The difference between this second embodiment and the first embodiment is that the chainsaw plate 6 includes a chainsaw head 63 and a chainsaw tail 61. A plurality of chainsaw bodies 62 are fixed between the chainsaw head 63 and the chainsaw tail 61. In this embodiment, only one chainsaw body 62 is provided. By controlling the number of chainsaw bodies 62, the length of the chainsaw plate 6 can be controlled, thereby increasing the cutting depth and meeting the requirements of deep mining or special tunnel construction. An auxiliary wheel 20 is rotatably connected to the chainsaw tail 61. The chain saw blade 14 cooperates with the auxiliary wheel 20 to ensure smoother rotation of the chain saw blade 14. The drive head 8 is fixed to the chainsaw head 63. Two hinged seats 28 are fixed to the end of the chainsaw head 63 near the chainsaw tail 61. Multiple hinged joints 29 are fixed to the end of the chainsaw tail 61 near the chainsaw head 63. The hinged joints 29 and the hinged seats 28 are fixed to each end of the chainsaw body 62. The hinged joints 29 and the hinged seats 28 are rotatably connected. A first rod 26 is telescopically connected to the chainsaw head 63 and fixed along the length of the chainsaw plate 6. A first socket 27 is defined on the side of the chainsaw body 62 near the chainsaw head 63, which slidably engages with the first rod 26. A fourth drive member 33, which is a fourth drive cylinder, is fixed to the chainsaw head 63 for driving the plurality of first rods 26 to slide. A second rod 25 is slidably connected to the chainsaw body 62, and a second socket is defined on the chainsaw tail 61, which plugs into and engages with the second rod 25. The first rod 26 extends through the first socket 27 and pushes the second rod 25 into the second socket, thereby providing a more stable connection between the chainsaw tail 61 and the chainsaw body 62. The coordination of the first and second rods 26 and 25 restrains the chainsaw body 62 and the chainsaw tail 61, thereby enhancing the securement of the chainsaw body 62 and the chainsaw tail 61. The chainsaw body 62 is provided with a limit stop, and the second rod 25 is provided with a limit slot that slidably engages with the limit stop. The limit slot is used to limit the sliding distance of the second rod 25. A magnet is provided at one end of the first rod 26 near the second rod 25. The magnet and the second rod 25 attract each other, making the second rod 25 more convenient to move.

[0051] A sliding spray seat 24 is slidingly connected to the chain saw plate 6, and the sliding spray seat 24 is slidingly set along the length direction of the chain saw plate 6. A support tube 23 is fixed on the sliding spray seat 24, and the support tube 23 is C-shaped and is tilted in the opposite direction away from the crawler walking mechanism 21. One end of the support tube 23 away from the sliding spray seat 24 is rotatably connected to the rotating wheel 21, and a plurality of spray nozzles 22 are fixed to the side wall of the support tube 23. The spray nozzles 22 are connected to the water tank 15. The liquid sprayed by the plurality of spray nozzles 22 constitutes a protective cover. The protective cover is C-shaped and can reduce dust diffusion and improve the environment of the lane.

[0052] The chain saw plate 6 is provided with an injection slide cavity 30 along its length direction, and an injection slider 34 that slides with the injection slide cavity 30 is fixed on the sliding nozzle seat 24. Extrusion strips 35 are fixed on both sides of the injection slide cavity 30, and the extrusion strips 35 abut against the injection slider 34 to limit the movement of the injection slider 34.

[0053] A pressure sensor 31 is fixed at the bottom of the bucket 5. The surface of the pressure sensor 31 is on the same plane as the bottom of the bucket 5. The pressure sensor 31 is electrically connected to the control valve. When the pressure of the pressure sensor 31 increases, the control valve reduces the driving speed of the first drive member 10. The pressure sensor 31 can detect the pressure change in time. When the pressure change value reaches a certain value, the speed of the first drive member 10 is reduced to improve the stability of the equipment.

[0054] The working principle of Example 2 is as follows: During operation, the chain saw head 63, chain saw tail 61, and multiple chain saw bodies 62 are combined to form chainsaw blades 6 of varying lengths, thereby increasing the cutting depth to meet the requirements of deep mining or special tunnel construction. Furthermore, the liquid ejected from the spray nozzle 22 forms a protective shield, reducing dust emission and diffusion within the tunnel, thereby improving the working environment. The pressure sensor 31 can promptly detect pressure changes. When the pressure change reaches a certain value, the speed of the first drive member 10 is reduced, allowing the chain saw blade 6 to cut the coal more stably.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
