Description

Technical Field

[0001] This invention relates to the field of hydraulic anchor removal vehicle technology for coal mines, and particularly to a walking mechanism and walking method of a hydraulic anchor removal vehicle for coal mines. Background Technology

[0002] The hydraulic anchor removal vehicle for coal mines is a device specifically designed for cutting anchorages during roof unloading in fully mechanized coal mining roadways.

[0003] Powered by an emulsion pump station (rated pressure 20MPA), the drive motor drives the hydraulic pump, which in turn drives the track to move. Simultaneously, the hydraulic motor-driven hydraulic pump can also provide power to the robotic arm and the cutter, enabling the robotic arm to adjust to a suitable position and angle, and driving the cutter to cut the lock.

[0004] The use of hydraulic anchor removal vehicles in coal mines can improve the efficiency of anchor removal and roof unloading, reduce the labor intensity of workers, and is safer and more reliable than traditional manual anchor removal methods. It effectively reduces safety hazards and avoids risks associated with manual operation, such as the risk of rock or coal block collapses at the top of the roadway. At the same time, it also helps reduce labor and material costs in coal mines, ensuring safe production and efficient operation.

[0005] In the prior art, Chinese invention patent CN109026098B discloses a hydraulic anchor removal vehicle, which includes an anchor removal mechanism, a robotic arm, a hydraulic control system, and a moving device. The moving device has a turntable, the robotic arm and hydraulic control system are mounted on the turntable, and the anchor removal mechanism is located at the front end of the robotic arm. The hydraulic anchor removal device is installed on the hydraulic anchor removal vehicle. By fixing the anchor removal mechanism to the robotic arm, the anchor removal mechanism is fixed in place. Then, the robotic arm, composed of a rotating arm and a telescopic arm, moves the anchor removal mechanism. Hydraulic cylinders are installed on the rotating arm and the telescopic arm, and the hydraulic control system controls the operation of the hydraulic cylinders, thereby achieving the rotation of the robotic arm. The hydraulic cylinder system provides stable control and smooth rotation. When removing anchor rods, only one person needs to operate the hydraulic anchor removal vehicle to complete the work, reducing the labor intensity of workers, improving work efficiency, and significantly enhancing work safety.

[0006] Problems compared to existing technologies: During the operation of a hydraulic anchor removal vehicle for coal mines, gravel easily gets trapped in the track gaps. Some existing hydraulic anchor removal vehicles for coal mines are inconvenient to clean the gravel trapped in the track gaps, which increases the weight of the tracks, increases the energy consumption of the hydraulic anchor removal vehicle for coal mines, and at the same time reduces the grip of the tracks.

A track chain link is drivenly connected to the outer side of the drive sprocket. The track chain link is drivenly connected to the driven sprocket. The track plate is rotatably connected to the outer side of the track chain link.

[0015] As a further embodiment of the present invention: a tensioning assembly is provided below the adjusting rod for adjusting the tension of the track chain links.

A mounting base is fixed to the extended end of the adjusting hydraulic cylinder by bolts. A round rod is rotatably connected to the middle position of the mounting base. The tensioning wheel is rotatably connected to one end of the round rod.

[0016] As a further embodiment of the present invention: the bottom of the lifting block is rotatably connected to a roller, the roller rotates along the outer wall of the elliptical wheel, a track is welded to the outer side of the frame, and the mounting base is slidably connected to the track.

[0017] As a further aspect of the present invention: a clearance groove is cut at the middle position of the top block, and the clearance groove avoids the track chain links.

[0018] As a further embodiment of the present invention: the chassis has grooves cut on both sides, and I-beams are slidably connected to both ends of the grooves; and multiple guide wheels are rotatably connected to the bottom of the frame.

[0019] A traveling mechanism for a hydraulic anchor-removing vehicle used in coal mines includes the following steps:

[0020] S1: Start the hydraulic motor. The hydraulic motor drives the drive sprocket to rotate. Under the limiting action of the guide wheel, the track chain links drive the driven sprocket to rotate, thereby driving multiple track plates to move. Under the tensioning action of the tension wheel, the friction between the track plates and the ground is used to propel the machine. Multiple hydraulic motors drive the track chain links on both sides to rotate in the same direction, and the coal mine hydraulic anchor removal car moves forward or backward. Multiple hydraulic motors drive the track chain links on both sides to rotate in opposite directions, and the coal mine hydraulic anchor removal car turns.

[0021] S2: While the hydraulic anchor-removing vehicle for coal mines is moving, the driven sprocket drives the drive toothed pulley to rotate. Under the transmission action of the toothed belt, the elliptical wheel rotates. At the same time, the elliptical wheel rotates and drives the lifting block to rise and fall. The lifting block drives the top rod to move up and down reciprocally through the helical spring, thereby cleaning the gravel trapped in the gaps of the hydraulic anchor-removing vehicle's tracks. The helical spring adjusts the movement distance of the top rod to avoid collision between the top block and the track plate.

[0022] S3: When the hydraulic anchor-removing vehicle for coal mines travels to a narrow space, the longitudinal double-outlet hydraulic cylinder is activated to move the push rod, thereby adjusting the spacing of the outriggers and allowing the hydraulic anchor-removing vehicle for coal mines to pass through narrow spaces. When the hydraulic anchor-removing vehicle for coal mines is in operation, the transverse double-outlet hydraulic cylinder is activated to adjust the length of the hydraulic anchor-removing vehicle for coal mines, and the longitudinal double-outlet hydraulic cylinder is activated to adjust the width of the hydraulic anchor-removing vehicle for coal mines, thereby adjusting the support area of ​​the hydraulic anchor-removing vehicle for coal mines and improving the support stability of the hydraulic anchor-removing vehicle for coal mines during operation.

[0023] S4: During the movement of the hydraulic anchor removal vehicle for coal mines, the shock absorber and the shock absorber spring work together to buffer the bumps during the movement of the hydraulic anchor removal vehicle for coal mines, reducing the vibration during the movement of the hydraulic anchor removal vehicle for coal mines. At the same time, the lifting hydraulic cylinder can drive the frame to rise and fall through the adjusting rod, so that the hydraulic anchor removal vehicle for coal mines can travel on inclined roads and operate stably on uneven ground.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. The hydraulic motor drives the drive sprocket and elliptical wheel to rotate. The rotating sprocket drives the coal mine hydraulic anchor removal vehicle to move, and the elliptical wheel drives the top block to move up and down to clean the gravel trapped in the track gaps of the coal mine hydraulic anchor removal vehicle, preventing the track weight from increasing and reducing the energy consumption of the coal mine hydraulic anchor removal vehicle. At the same time, it ensures the traction of the coal mine hydraulic anchor removal vehicle track.

[0026] 2. By using a longitudinal double-outlet hydraulic cylinder to move the push rod, the spacing between the outriggers is adjusted, allowing the hydraulic anchor unloading vehicle for coal mines to pass through narrow spaces, thus expanding its application range. By using a transverse double-outlet hydraulic cylinder to adjust the length of the hydraulic anchor unloading vehicle for coal mines, the support area of ​​the vehicle is adjusted, improving the support stability during operation and ensuring the safety of the vehicle's operation.

[0027] 3. The lifting hydraulic cylinder can drive the frame to rise and fall through the adjusting rod, thus enabling the hydraulic anchor removal vehicle for coal mines to perform support operations at various heights.

[0044] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0047] Example 1:

[0048] like Figure 1-8 As shown, a walking mechanism for a hydraulic anchor removal vehicle used in coal mines includes a chassis 100, a frame 200 mounted below the chassis 100, and a transmission assembly and a cleaning assembly disposed on one side of the frame 200. This mechanism drives the hydraulic anchor removal vehicle to move while simultaneously cleaning debris trapped in the track gaps. The transmission assembly includes a driven sprocket 101 disposed at one end of the frame 200 and a drive toothed pulley 102 fixedly connected to the outside of the driven sprocket 101. A hydraulic motor 501 is bolted to one end of the frame 200, and a drive sprocket 502 is bolted to the rotating end of the hydraulic motor 501. A track chain link 503 is driven to the outside of the drive sprocket 502. The walking assembly is disposed on one side of the frame 200 for driving the movement of the hydraulic anchor removal vehicle. The walking assembly includes track plates 504. Driven by a hydraulic pump, a hydraulic motor 501 drives a drive sprocket 502 to rotate. The drive sprocket 502 drives a track chain link 503 to rotate, which in turn drives a driven sprocket 101 to rotate, thereby moving multiple track plates 504. The friction between the track plates 504 and the ground is used to propel the hydraulic anchor removal vehicle in the coal mine. The track chain link 503 is connected to the driven sprocket 101. The track plates 504 are rotatably connected to the outside of the track chain link 503. During the actual transfer of the hydraulic anchor removal vehicle in the coal mine, multiple hydraulic motors 501 drive the track chain links 503 on both sides to rotate in the same direction, causing the hydraulic anchor removal vehicle to move forward or backward. When multiple hydraulic motors 501 drive the track chain links 503 on both sides to rotate in opposite directions, the hydraulic anchor removal vehicle in the coal mine can turn.

[0049] A toothed belt 103 is driven to the outer side of the drive toothed pulley 102. One end of the toothed belt 103 is driven to the driven toothed pulley 104. It should be noted that the toothed belt 103, the drive toothed pulley 102, and the driven toothed pulley 104 all have uniformly welded protrusions on their outer sides, and the inner wall of the toothed belt is uniformly cut with grooves. The protrusions and grooves engage to prevent slippage between the toothed belt and the toothed pulleys, ensuring a constant transmission ratio between the toothed belt 103, the drive toothed pulley 102, and the driven toothed pulley 104. One end of the driven toothed pulley 104 is bolted to a drive rod 105. The rotation of the driven sprocket 101 simultaneously drives the drive rod 105 to rotate, thus driving the cleaning assembly of the hydraulic anchor removal vehicle in the coal mine. Simultaneously, the rotation of the driven sprocket 101 drives the drive toothed pulley 102 to rotate. The drive toothed pulley 102, through the transmission of the toothed belt 103, drives the driven toothed pulley 104 to rotate, thereby driving the elliptical wheel 206 to rotate via the drive rod 105.

[0050] In practical applications, the hydraulic anchor removal vehicle for coal mines operates in the coal mine environment. It utilizes the friction between the track plates 504 and the ground to propel the vehicle. Crushed stones at the coal mine site are easily pressed into the track gaps by the track. A cleaning component is used to remove the crushed stones stuck in the track. The cleaning component includes a top block 205 and an elliptical wheel 206 bolted to one end of a drive rod 105. A support arm 201 is bolted to one side of the frame 200. A lifting block 202 is slidably connected to one end of the support arm 201. The rotation of the elliptical wheel 206 drives the lifting block 202 to move up and down along the support arm 201. Notably, a roller 300 is rotatably connected to the bottom of the lifting block 202. The roller 300 rotates along the outer wall of the elliptical wheel 206, and the roller 300 uses its own rotation to generate sliding friction. The friction between the elliptical wheel 206 and the lifting block 202 is reduced by rolling friction. A helical spring 203 is fixed inside the lifting block 202 by bolts. One end of the helical spring 203 is fixed to a top rod 204 by bolts. The top block 205 is fixed above the top rod 204 by bolts. The helical spring 203 pushes the top rod 204 with its elastic force. Furthermore, during the process of cleaning up the mixed gravel, when the top block 205 comes into contact with the track plate 504, the helical spring 203 is compressed, and the top block 205 stops rising, thus avoiding collision between the top block 205 and the track plate 504. It is worth noting that a clearance groove 400 is cut in the middle of the top block 205. The clearance groove 400 avoids the track chain link 503, preventing the top block 205 from interfering with the movement of the track chain link.

[0051] It also includes an adjustment assembly located inside the chassis 100 for adjusting the footprint of the hydraulic anchor-removing vehicle for coal mines. The adjustment assembly includes a transverse double-outlet hydraulic cylinder 301 located in the middle of the chassis 100 and longitudinal double-outlet hydraulic cylinders 303 installed at both ends of the transverse double-outlet hydraulic cylinder 301. The transverse double-outlet hydraulic cylinder 301 extends and retracts, causing the crossbeam 302 to move, thereby adjusting the length of the hydraulic anchor-removing vehicle for coal mines. The longitudinal double-outlet hydraulic cylinders 303 are fixed inside the crossbeam 302 by bolts. The extended end of the longitudinal double-outlet hydraulic cylinder 303 is fixed with a push rod 304 by bolts. The push rod 304 is slidably connected to the inner wall of the crossbeam 302, ensuring that the push rod 304 is always on the same axis as the crossbeam 302 during movement, thereby limiting the movement trajectory of the push rod 304. One end of the push rod 304 is fixed with a support leg 305 by bolts. The longitudinal double-outlet hydraulic cylinder 303 drives the push rod 304 to move, thereby adjusting the spacing of the support legs 305 and realizing the adjustment of the width of the hydraulic anchor removal vehicle for coal mines.

[0052] The two ends of the transverse double-rod hydraulic cylinder 301 are fixed with crossbeams 302 by bolts. The two sides of the chassis 100 are cut with sliding grooves 500. The two ends of the sliding grooves 500 are slidably connected with I-beams 600. One end of the I-beams 600 is fixedly connected to the crossbeams 302. When the crossbeams 302 move, the I-beams 600 will slide along the sliding grooves 500, ensuring that the crossbeams 302 are always on the same horizontal plane as the chassis 100 during the movement, thereby realizing the positioning of the movement trajectory of the crossbeams 302.

[0053] In this embodiment, the operator drives the hydraulic motor 501, which in turn drives the drive sprocket 502 and the elliptical wheel 206 to rotate. The rotating sprocket 502 drives the hydraulic anchor removal vehicle in the coal mine to move. The elliptical wheel 206 drives the top block 205 to move up and down, clearing debris trapped in the track gaps of the hydraulic anchor removal vehicle, preventing an increase in track weight, reducing energy consumption, and ensuring the track's grip. Since the working environment of the hydraulic anchor removal vehicle is relatively complex, when it travels to a narrower area, the longitudinal double-outlet hydraulic cylinder 303 is activated to move the push rod 304. The movement of the outriggers 305 adjusts the spacing between them, allowing the hydraulic anchor unloading vehicle to pass through narrow spaces and expanding its application range. Furthermore, when the hydraulic anchor unloading vehicle operates above the chassis 100, the transverse double-outlet hydraulic cylinder 301 is activated to adjust the length of the vehicle, and the longitudinal double-outlet hydraulic cylinder 303 is activated to adjust the width, thereby adjusting the support area and improving the support stability during operation, ensuring the safety of the vehicle.

[0054] Example 2:

[0055] like Figure 4-7 As shown, the following improvements are made based on Embodiment 1: A support assembly is provided inside the outrigger 305 to support the chassis 100 of the hydraulic anchor-removing vehicle for coal mines. The support assembly includes an adjusting rod 405. A shock absorber 401 is bolted to the top of the outrigger 305, and a shock absorber spring 402 is bolted to the outer side of the shock absorber 401. Since the flatness of the ground is difficult to guarantee during actual use of the hydraulic anchor-removing vehicle for coal mines, the shock absorber 401 and the shock absorber spring 402 work together to buffer the bumps during the vehicle's movement. One end of the shock absorber spring 402 is bolted to a lifting plate 403, and the lower part of the lifting plate 403 is bolted to... A lifting hydraulic cylinder 404 is fixedly installed, and an adjusting rod 405 is fixed to the extended end of the lifting hydraulic cylinder 404 by bolts. The adjusting rod 405 is fixedly connected to the frame 200. Furthermore, when the hydraulic anchor removal vehicle for coal mines is working, it needs to be stably supported. However, when there are potholes at the work site, and the equipment happens to be located in a pothole, it is difficult to stably support the hydraulic anchor removal vehicle for coal mines, and the equipment is prone to shaking during operation. At this time, the lifting hydraulic cylinder 404 can drive the frame 200 to rise and fall through the adjusting rod 405, thereby adjusting the support height of the hydraulic anchor removal vehicle for coal mines. This allows the hydraulic anchor removal vehicle for coal mines to work stably even in potholes, avoiding equipment damage caused by shaking.

[0056] A tensioning assembly is provided below the adjusting rod 405 for adjusting the tension of the track chain links 503. The tensioning assembly includes a tensioning wheel 604. An adjusting hydraulic cylinder 601 is bolted to the lower part of the adjusting rod 405. A mounting base 602 is bolted to the extended end of the adjusting hydraulic cylinder 601. A track 700 is welded to the outer side of the frame 200. The mounting base 602 is slidably connected to the track 700. A round rod 603 is rotatably connected to the middle position of the mounting base 602. The tensioning wheel 604 is rotatably connected to one end of the round rod 603, allowing the tensioning wheel 604 to rotate while moving up and down along the track 700. When it is necessary to adjust the track tension of the hydraulic anchor-removing vehicle for coal mines, the adjusting hydraulic cylinder 601 extends and retracts, driving the mounting base 602 to move up and down along the track 700, thereby adjusting the height of the round rod 603. The round rod 603 drives the tensioning wheel 604 to move up and down, thereby adjusting the tension of the track of the hydraulic anchor-removing vehicle for coal mines. Multiple guide wheels 800 are rotatably connected to the bottom of the frame 200.

[0057] In this embodiment, the operator activates the lifting hydraulic cylinder 404, which can drive the frame 200 to rise and fall via the adjusting rod 405. This allows the hydraulic anchor unloading vehicle for coal mines to perform support operations at various heights, enabling it to meet the requirements of anchor unloading operations on uneven ground. The round rod 603 drives the tension wheel 604 to rise and fall, thereby adjusting the tension of the tracks of the hydraulic anchor unloading vehicle for coal mines and enriching its functionality.

[0058] A traveling mechanism for a hydraulic anchor-removing vehicle used in coal mines includes the following steps:

[0059] S1: Start the hydraulic motor 501. The hydraulic motor 501 drives the drive sprocket 502 to rotate. Under the limiting action of the guide wheel 800, the track chain link 503 drives the driven sprocket 101 to rotate, thereby driving multiple track plates 504 to move. Under the tensioning action of the tension wheel 604, the friction between the track plates 504 and the ground is used to propel the machine to move. Multiple hydraulic motors 501 drive the track chain links 503 on both sides to rotate in the same direction, and the coal mine hydraulic anchor removal vehicle moves forward or backward. Multiple hydraulic motors 501 drive the track chain links 503 on both sides to rotate in opposite directions, and the coal mine hydraulic anchor removal vehicle turns.

[0060] S2: While the hydraulic anchor-removing vehicle for coal mines is moving, the driven sprocket 101 drives the drive toothed pulley 102 to rotate. Under the transmission action of the toothed belt 103, the elliptical wheel 206 rotates. While the elliptical wheel 206 rotates, it drives the lifting block 202 to rise and fall. The lifting block 202 drives the top rod 204 to move up and down reciprocally through the helical spring 203, thereby cleaning the gravel trapped in the gaps of the hydraulic anchor-removing vehicle's tracks. The helical spring 203 adjusts the movement distance of the top rod 204 to prevent the top block 205 from colliding with the track plate 504.

[0061] S3: When the hydraulic anchor-removing vehicle for coal mines travels to a narrow space, the longitudinal double-outlet hydraulic cylinder 303 is activated to drive the push rod 304 to move, thereby adjusting the spacing of the outriggers 305, allowing the hydraulic anchor-removing vehicle for coal mines to pass through narrow spaces. When the hydraulic anchor-removing vehicle for coal mines is in operation, the transverse double-outlet hydraulic cylinder 301 is activated to adjust the length of the hydraulic anchor-removing vehicle for coal mines, and the longitudinal double-outlet hydraulic cylinder 303 is activated to adjust the width of the hydraulic anchor-removing vehicle for coal mines, thereby adjusting the support area of ​​the hydraulic anchor-removing vehicle for coal mines and improving the support stability of the hydraulic anchor-removing vehicle for coal mines during operation.

[0062] S4: During the movement of the hydraulic anchor removal vehicle for coal mines, the shock absorber 401 and the shock absorber spring 402 work together to buffer the bumps during the movement of the hydraulic anchor removal vehicle for coal mines, reducing the vibration during the movement of the hydraulic anchor removal vehicle for coal mines. At the same time, the lifting hydraulic cylinder 404 can drive the frame 200 to rise and fall through the adjusting rod 405, so that the hydraulic anchor removal vehicle for coal mines can travel on inclined roads and operate stably on uneven ground.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
