[0046] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0047] Embodiment 1:

[0048] like Figure 1-8 As shown, a walking mechanism of a hydraulic anchor removal vehicle for coal mines comprises a chassis 100, a frame 200 installed under the chassis 100, and a transmission assembly and a cleaning assembly arranged on one side of the frame 200, which are used to drive the hydraulic anchor removal vehicle for coal mines to travel and drive the cleaning operation of the gravel mixed in the gap of the crawler track. The transmission assembly comprises a driven sprocket 101 arranged at one end of the frame 200 and a driving toothed belt wheel 102 fixedly connected to the outer side of the driven sprocket 101. A hydraulic motor 501 is fixed to one end of the frame 200 by bolts, and a driving sprocket 502 is fixed to the rotating end of the hydraulic motor 501 by bolts. The outer side of the driving sprocket 502 is transmission-connected to the crawler chain ring 503. A walking assembly is arranged on one side of the frame 200 to drive the movement of the hydraulic anchor removal vehicle for coal mines. The walking assembly includes track shoes 504. Under the driving action of the hydraulic pump, the hydraulic motor 501 drives the active sprocket 502 to rotate, the active sprocket 502 drives the track chain ring 503 to rotate, the track chain ring 503 drives the driven sprocket 101 to rotate, thereby driving multiple track shoes 504 to move, and the friction between the track shoes 504 and the ground is used to promote the walking of the hydraulic anchor removal vehicle for coal mines. The track chain ring 503 is transmission-connected to the driven sprocket 101, and the track shoes 504 are rotationally connected to the outer side of the track chain ring 503. During the actual transfer process of the hydraulic anchor removal vehicle for coal mines, multiple hydraulic motors 501 drive the track chain rings 503 on both sides to rotate in the same direction, and the hydraulic anchor removal vehicle for coal mines moves forward or backward. Multiple hydraulic motors 501 drive the track chain rings 503 on both sides to rotate in the opposite direction, and the hydraulic anchor removal vehicle for coal mines turns.

[0049] The outer side of the driving toothed belt wheel 102 is connected to the transmission with a toothed belt 103, and one end of the toothed belt 103 is connected to the driven toothed belt wheel 104. It should be noted that the toothed belt 103, the driving toothed belt wheel 102 and the driven toothed belt wheel 104, the outer side of the toothed belt wheel is uniformly welded with protrusions, and the inner wall of the toothed belt is uniformly cut with grooves. The protrusions cooperate with the grooves to prevent the toothed belt and the toothed belt wheel from slipping, thereby ensuring that the transmission ratio between the toothed belt 103, the driving toothed belt wheel 102 and the driven toothed belt wheel 104 remains constant. A driving rod 105 is fixed to one end of the driven toothed belt wheel 104 by bolts. When the driven sprocket 101 rotates, the driving rod 105 is driven to rotate, thereby driving the cleaning component of the hydraulic anchor unwinding vehicle for coal mines to work. When the driven sprocket 101 rotates, the driving toothed belt wheel 102 is driven to rotate. The driving toothed belt wheel 102 uses the transmission of the toothed belt 103 to drive the driven toothed belt wheel 104 to rotate, thereby driving the elliptical wheel 206 to rotate through the driving rod 105.

[0050] In actual application, the hydraulic anchor remover for coal mines works in a coal mine environment, and the friction between the track shoe 504 and the ground is used to drive the hydraulic anchor remover for coal mines to move. The broken stones at the coal mine site are easily stuck in the gaps of the track by pressing the track. The cleaning component is used to clean the broken stones stuck in the track. The cleaning component includes a top block 205 and an elliptical wheel 206 fixed to one end of the driving rod 105 by bolts. A support arm 201 is fixed to one side of the frame 200 by bolts, and 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 reciprocate up and down along the support arm 201. It is worth mentioning that the bottom of the lifting block 202 is rotatably connected to a roller 300, and the roller 300 rotates along the outer wall of the elliptical wheel 206. The roller 300 uses its own rotation to rotate the sliding friction. It becomes rolling friction, reducing the friction between the elliptical wheel 206 and the lifting block 202. The interior of the lifting block 202 is fixed with a coil spring 203 by bolts, and one end of the coil spring 203 is fixed with a push rod 204 by bolts. The push block 205 is fixed above the push rod 204 by bolts, and the coil spring 203 uses elastic force to push the push rod 204. Furthermore, when the top block 205 contacts the track shoe 504 during the cleaning of mixed gravel, the coil spring 203 is compressed, and the top block 205 stops rising to avoid the top block 205 from colliding with the track shoe 504. It is worth mentioning that an avoidance groove 400 is cut in the middle position of the top block 205, and the avoidance groove 400 avoids the track chain ring 503 to prevent the top block 205 from interfering with the track chain ring in motion.

[0051] The chassis 100 also includes an adjustment component for adjusting the size of the floor space occupied by the hydraulic anchor unloading vehicle for coal mines. The adjustment component includes a transverse double-rod hydraulic cylinder 301 arranged in the middle of the chassis 100 and a longitudinal double-rod hydraulic cylinder 303 installed at both ends of the transverse double-rod hydraulic cylinder 301. The transverse double-rod hydraulic cylinder 301 is extended and retracted to drive the crossbeam 302 to move, thereby adjusting the length of the hydraulic anchor unloading vehicle for coal mines. The longitudinal double-rod hydraulic cylinder 303 is fixed to the inside of the crossbeam 302 by bolts. The extended end of the longitudinal double-rod hydraulic cylinder 303 is fixed with a push rod 304 by bolts, and the push rod 304 is slidably connected to the inner wall of the beam 302 to ensure that the push rod 304 is always on the same axis as the beam 302 during the movement, thereby limiting the movement trajectory of the push rod 304, and one end of the push rod 304 is fixed with a support leg 305 by bolts, and the longitudinal double-rod hydraulic cylinder 303 drives the push rod 304 to move, thereby adjusting the spacing of the support legs 305, thereby realizing the adjustment of the width of the hydraulic anchor withdrawal vehicle for coal mines.

[0052] The two ends of the transverse double-rod hydraulic cylinder 301 are fixed with a crossbeam 302 by bolts, and the two sides of the chassis 100 are cut with a slide groove 500. The two ends of the slide groove 500 are slidably connected with an I-beam 600. One end of the I-beam 600 is fixedly connected to the crossbeam 302. The movement of the crossbeam 302 will drive the I-beam 600 to slide along the slide groove 500, ensuring that the crossbeam 302 is always in the same horizontal plane with the chassis 100 during the movement, thereby realizing the positioning of the moving trajectory of the crossbeam 302.

[0053] In this embodiment, the operator drives the hydraulic motor 501, and the hydraulic motor 501 drives the active sprocket 502 and the elliptical wheel 206 to rotate, and the rotating sprocket 502 drives the hydraulic anchor unloading vehicle for coal mines to move, and the elliptical wheel 206 drives the top block 205 to move up and down, and the gravel mixed in the gap of the crawler track of the hydraulic anchor unloading vehicle for coal mines is cleaned to prevent the crawler track from increasing its own weight, and reduce the energy consumption of the hydraulic anchor unloading vehicle for coal mines. At the same time, the grip of the crawler track of the hydraulic anchor unloading vehicle for coal mines is guaranteed. The operating environment of the hydraulic anchor unloading vehicle for coal mines is relatively complex. When the hydraulic anchor unloading vehicle for coal mines walks to a narrow place, the longitudinal double-rod hydraulic cylinder 303 is started to drive the push rod 304 to move The hydraulic anchor unloading vehicle for coal mines is moved to adjust the spacing of the outriggers 305, so that the hydraulic anchor unloading vehicle for coal mines can pass through narrow spaces, thereby expanding the scope of use of the hydraulic anchor unloading vehicle for coal mines. Furthermore, the hydraulic anchor unloading vehicle for coal mines operates above the chassis 100. When the hydraulic anchor unloading vehicle for coal mines is operating, the horizontal double-rod hydraulic cylinder 301 is started to adjust the length of the hydraulic anchor unloading vehicle for coal mines, and the longitudinal double-rod hydraulic cylinder 303 is started to adjust the width of the hydraulic anchor unloading vehicle for coal mines, thereby adjusting the support area of ​​the hydraulic anchor unloading vehicle for coal mines, improving the support stability of the hydraulic anchor unloading vehicle for coal mines during the working process, and ensuring the safety of the hydraulic anchor unloading vehicle for coal mines.

[0054] Embodiment 2:

[0055] like Figure 4-7 As shown, the following improvements are made on the basis of the first embodiment: a support assembly is provided inside the support leg 305 for supporting the chassis 100 of the hydraulic anchor unloading vehicle for coal mines, and the support assembly includes an adjusting rod 405. A shock absorbing cylinder 401 is fixed to the top of the support leg 305 by bolts, and a shock absorbing spring 402 is fixed to the outside of the shock absorbing cylinder 401 by bolts. The flatness of the ground during the actual use of the hydraulic anchor unloading vehicle for coal mines is difficult to ensure. The shock absorbing cylinder 401 cooperates with the shock absorbing spring 402 to buffer the bumps during the travel of the hydraulic anchor unloading vehicle for coal mines. A lifting plate 403 is fixed to one end of the shock absorbing spring 402 by bolts, and the lower part of the lifting plate 403 is fixed by bolts. A lifting hydraulic cylinder 404 is fixed, and the 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 withdrawal vehicle for coal mine is working, it is necessary to firmly support the hydraulic anchor withdrawal vehicle for coal mine. When there are potholes at the work site and the equipment happens to be located in the potholes, it is difficult to firmly support the hydraulic anchor withdrawal vehicle for coal mine, and the equipment is prone to shaking when working. 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 withdrawal vehicle for coal mine, so that the hydraulic anchor withdrawal vehicle for coal mine can also work stably in potholes, avoiding damage to the equipment caused by shaking of the device.

[0056] A tensioning assembly is provided below the adjusting rod 405 for adjusting the tensioning force of the crawler chain ring 503. The tensioning assembly includes a tensioning wheel 604. An adjusting hydraulic cylinder 601 is fixed to the lower side of the adjusting rod 405 by bolts. A mounting seat 602 is fixed to the extended end of the adjusting hydraulic cylinder 601 by bolts. A track 700 is welded to the outer side of the frame 200. The mounting seat 602 is slidably connected to the track 700. A round rod 603 is rotatably connected to the middle position of the mounting seat 602. The tensioning wheel 604 is rotatably connected to one end of the round rod 603, so that the tensioning wheel 604 can rotate while rising and falling along the track 700. When it is necessary to adjust the track tension of the hydraulic anchor removal vehicle for coal mines, the hydraulic cylinder 601 is adjusted to extend and retract to drive the mounting seat 602 to rise and fall along the track 700, thereby adjusting the height of the round rod 603. The round rod 603 drives the tensioning wheel 604 to rise and fall, thereby adjusting the tension of the track of the hydraulic anchor removal vehicle for coal mines. A plurality of guide wheels 800 are rotatably connected at the bottom of the frame 200.

[0057] In this embodiment, the operator starts the lifting hydraulic cylinder 404, and the lifting hydraulic cylinder 404 can drive the frame 200 to rise and fall through the adjusting rod 405, so that the hydraulic anchor withdrawal vehicle for coal mines can perform supporting operations at various heights, so that the hydraulic anchor withdrawal vehicle for coal mines can meet the requirements of anchor withdrawal operations on uneven ground. The round rod 603 drives the tensioning wheel 604 to rise and fall, so as to adjust the tensioning force of the track of the hydraulic anchor withdrawal vehicle for coal mines, thereby enriching the functionality of the hydraulic anchor withdrawal vehicle for coal mines.

The elliptical wheel 206 rotates and drives the lifting block 202 to move up and down. The lifting block 202 drives the push rod 204 to reciprocate up and down through the spiral spring 203, so as to clean up the gravel mixed in the gap of the track of the hydraulic anchor unloading vehicle. The spiral spring 203 adjusts the movement distance of the push rod 204 to avoid the collision between the push block 205 and the track shoe 504;

[0061] S3: When the hydraulic anchor withdrawal vehicle for coal mines moves to a narrow place, the longitudinal double-rod hydraulic cylinder 303 is started to drive the push rod 304 to move, thereby adjusting the spacing of the legs 305, so that the hydraulic anchor withdrawal vehicle for coal mines can pass through the narrow space.
