For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0043] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0044] The present embodiment relates to a mining explosion-proof trackless rubber-tyred side wall cleaning vehicle, which is used to clean the side walls of underground tunnels in coal mines.

[0045] In terms of overall structure, Figure 1 As shown, the mining explosion-proof trackless rubber-tyred sidewall cleaning vehicle of this embodiment includes a roller brush device 2 and a high-pressure cleaning device 3 arranged on a chassis 1 of the vehicle.

[0046] The roller brush device 2 includes a driving mechanism disposed at the front of the chassis 1 and a roller brush assembly 21 disposed at the driving end of the driving mechanism, and the driving mechanism drives the roller brush assembly 21 to brush away dust on the side wall of the lane. The high-pressure cleaning device 3 includes a high-pressure water pump disposed at the rear of the chassis 1, a high-pressure sprayer 31 for cleaning the side wall of the lane, and a high-pressure pipeline connecting the high-pressure water pump and the high-pressure sprayer 31.

[0047] As described above, the mining explosion-proof trackless rubber-tyred side wall cleaning vehicle of this embodiment can brush and flush the side walls of underground mine tunnels through the arrangement of the roller brush device 2 and the high-pressure cleaning device 3, effectively removing dust on the side walls of the tunnels, thereby improving the cleaning effect of the tunnels.

[0048] Based on the above overall introduction, the mining explosion-proof trackless rubber-wheeled side wall cleaning vehicle of this embodiment is used in coal mines to clean the tunnels in coal mines, especially the dust on the tunnel walls. Since the working environment in coal mines is relatively harsh and the dust in the tunnels is mostly coal ash, the cleaning vehicle of this embodiment adopts a conventional explosion-proof trackless rubber-wheeled vehicle well known to those skilled in the art to meet the explosion-proof requirements in coal mines. A water tank is provided on the vehicle body, and the high-pressure water pump at the rear of the cleaning vehicle chassis 1 can supply water in the water tank to the high-pressure cleaning device 3, and the high-pressure water pump is driven by the power system of the cleaning vehicle.

[0049] As a preferred implementation form, combined with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a first translation mechanism 32 is provided at the rear portion of the chassis 1 of the present embodiment, and the high-pressure sprayer 31 can be driven by the first translation mechanism 32 and move along the width direction of the chassis 1. It can be understood that the first translation mechanism 32 can change the distance from the high-pressure sprayer 31 to the side wall of the tunnel, so as to make adjustments according to actual working conditions, so that the water flow sprayed by the high-pressure sprayer 31 can effectively flush the side wall of the tunnel to remove dust on the side wall of the tunnel.

[0050] In a specific implementation, the first translation mechanism 32 may optionally include a sleeve disposed at the rear of the chassis 1, a telescopic rod nested in the sleeve, and a translation cylinder with two ends connecting the telescopic rod and the sleeve, and the translation cylinder can drive the telescopic rod to move along the width direction of the chassis 1, thereby changing the distance from the high-pressure spray tool 31 to the side wall of the lane. Other conventional structures known to those skilled in the art can also be used, as long as they can drive the high-pressure spray tool 31 to move along the width direction of the chassis 1.

[0051] As a preferred implementation form, the high-pressure sprayer 31 of this embodiment includes a high-pressure nozzle having a plurality of high-pressure nozzles 311, each of which is arranged at intervals along the length direction of the high-pressure nozzle, and each of which is used to wash the side wall of the lane. The high-pressure water flow sprayed by the high-pressure nozzle 311 can effectively peel off the dust attached to the side wall of the lane, which is conducive to improving the cleaning effect of the lane.

[0052] In a specific implementation, the high-pressure nozzle 311 at the top of the high-pressure nozzle can be preferably arranged to tilt upward, and the high-pressure nozzle 311 at the bottom of the high-pressure nozzle can be preferably arranged to tilt downward, so that the water flow sprayed by the high-pressure nozzle 311 can cover the entire side wall of the tunnel. At the same time, each high-pressure nozzle 311 can be tilted toward the front of the cleaning vehicle so that the high-pressure water flow forms a certain angle with the side wall of the tunnel. Compared with the high-pressure water flow sprayed vertically toward the side wall of the tunnel, the flushing effect can be improved, and the dust on the side wall of the tunnel can be effectively removed. In addition, the high-pressure nozzle 311 is connected to the high-pressure nozzle through a hose, and the hose can be a steel wire hose that can be bent and has a certain strength. During the cleaning vehicle travel, when the high-pressure nozzle 311 accidentally touches the side wall of the tunnel, the hose can be bent by force to prevent the high-pressure sprayer 31 from being damaged by external forces.

[0053] It is understandable that the height of the side wall of the lane is much greater than the height of the cleaning vehicle. Therefore, in order to allow the high-pressure nozzle to flush the entire side wall of the lane, the top of the high-pressure nozzle will be higher than the roof of the vehicle. When the cleaning vehicle moves or relocates, the top of the high-pressure nozzle will collide with the lane wall or the equipment in the lane. Therefore, as a preferred implementation form, the high-pressure nozzle of this embodiment includes a hinged first high-pressure nozzle 312 and a second high-pressure nozzle 313, and a driving cylinder 33 hinged at both ends of the first high-pressure nozzle 312 and the second high-pressure nozzle 313, respectively. The first high-pressure nozzle 312 is arranged vertically, and the driving cylinder 33 is used to drive the second high-pressure nozzle 313 to switch between a vertical state and a horizontal state at any angle. When the cleaning vehicle finishes flushing the side wall of the lane or the cleaning vehicle is transferred to a site, the second high-pressure nozzle 313 can be driven by the driving cylinder 33 to rotate from a vertical state to a horizontal state, so that the second high-pressure nozzle 313 is folded and stored to facilitate the movement of the cleaning vehicle.

[0054] Specifically, the first high-pressure nozzle 312 is arranged on a vertically arranged support arm, which is connected to the end of the telescopic rod. A folding arm is hinged at the top of the support arm. The support arm and the folding arm are respectively provided with the first high-pressure nozzle 312 and the second high-pressure nozzle 313. Both ends of the driving cylinder 33 are hinged on the support arm and the folding arm to drive the folding arm to drive the second high-pressure nozzle 313 to rotate.

[0055] In addition, during the specific implementation, a spray gun connected to a high-pressure water pump may be provided at the rear of the cleaning vehicle for use by the operator to clean the part in the lane, so as to improve the cleaning effect of the cleaning vehicle on the lane.

[0056] In order to ensure that the roller brush assembly 21 can always be in close contact with the side wall of the lane to clean it during the operation of the cleaning vehicle, as a preferred implementation form, combined with Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the driving mechanism of this embodiment includes a second translation mechanism 22 arranged at the front of the chassis 1, a swing mechanism 23 driven by the second translation mechanism 22 and moving along the width direction of the chassis 1, and a lifting mechanism 24 arranged on the swing end of the swing mechanism 23, the swing mechanism 23 is used to drive the lifting mechanism 24 to swing at a preset angle in the horizontal direction, and the roller brush assembly 21 is arranged on the lifting end of the lifting mechanism 24. To ensure that the roller brush assembly 21 can be driven by the driving mechanism to move and brush the side wall of the lane.

[0057] In a specific implementation, the second translation mechanism 22 includes a crossbeam 221 disposed at the front of the chassis 1, a translation seat 222 slidably disposed on the crossbeam 221, and a support beam 223 disposed transversely on the translation seat 222. A transversely disposed rack 226 is disposed above the support beam 223, a first motor 224 is disposed on the translation seat 222, and a gear 225 meshing with the rack 226 is disposed on the output shaft of the first motor 224. The first motor 224 can drive the translation seat 222 to move along the crossbeam 221 through the meshing of the gear 225 and the rack 226, thereby driving the support beam 223 to move. Other conventional structures known to those skilled in the art can also be used, as long as they can drive the roller brush assembly 21 to move along the width direction of the chassis 1.

[0058] Meanwhile, the swing mechanism 23 includes a swing seat 232 hinged at the end of the support beam 223, and a second motor 231 disposed on the swing seat 232. The second motor 231 can drive the swing seat 232 to rotate at a preset angle around the end of the support beam 223, thereby driving the upgrade mechanism disposed on the swing seat 232 to move. Other conventional structures known to those skilled in the art can also be used, as long as they can drive the roller brush assembly 21 to swing in the horizontal direction.

[0059] Furthermore, the lifting mechanism 24 includes a column 241 vertically arranged on the swing seat 232, a sleeve 242 nested in the outer periphery of the column 241, and a push rod 243 connected between the sleeve 242 and the swing seat 232 at both ends. The push rod 243 can drive the sleeve 242 to slide along the height direction of the column 241 to change the distance between the sleeve 242 and the swing seat 232, and the sleeve 242 serves as a lifting end, and the roller brush assembly 21 of this embodiment is arranged on the side of the sleeve 242. Other conventional structures known to those skilled in the art can also be used, as long as they can drive the roller brush assembly 21 to rise and fall.

[0060] In this embodiment, as a preferred implementation form, combined with Figure 5 , Figure 6 and Figure 7As shown, the roller brush assembly 21 of this embodiment includes a shell 211 arranged on the lifting end, a support frame 212 arranged on the shell 211, and a roller brush body 213 rotatably arranged on the support frame 212, the roller brush body 213 is used to brush away dust on the side walls of the alley. In a specific implementation, a third motor 216 is provided on the support frame 212 for driving the roller brush body 213 to rotate. At the same time, a scraper 214 for scraping dust on the side wall of the tunnel is provided on one side of the shell 211, further improving the dust removal effect, and an auxiliary nozzle 215 pointing to the side wall of the tunnel is provided on the shell 211, and the auxiliary nozzle 215 is connected to a high-pressure water pump, which can spray water on the side wall of the tunnel during the brushing process, which is beneficial to improve the cleaning effect of the side wall of the tunnel. In specific implementation, the scraper 214 can be preferably arranged on the side of the shell 211 close to the rear of the vehicle body, so that the scraper 214 can not only scrape off the dust on the side wall of the tunnel, but also scrape off the accumulated water on the side wall of the tunnel, thereby ensuring the cleanliness of the side wall of the tunnel.

[0061] When the cleaning vehicle of this embodiment scrubs and rinses the sidewalls of the lane, sewage and dust will also fall on the ground in the lane. Therefore, in order to clean the entire lane, as a preferred implementation form, Figure 1 , Figure 8 , Fig. 9 As shown, the cleaning vehicle of this embodiment also includes a low-pressure cleaning device 4 arranged on the chassis 1, and the low-pressure cleaning device 4 includes a low-pressure water pump 41, a low-pressure pipeline 42 connected to the low-pressure water pump 41, and a low-pressure sprayer 43 arranged on the low-pressure pipeline 42. The low-pressure sprayer 43 is used to flush the ground to improve the cleaning effect of the lane.

[0062] Specifically, as a preferred implementation form, the low-pressure sprayer 43 includes a water sprinkling branch 431 and a counter branch 433 connected to the low-pressure pipeline 42 at the bottom of the chassis 1. The water sprinkling branch 431 and the counter branch 433 are arranged along the width direction of the chassis 1. The left and right ends of the water sprinkling branch 431 are provided with water sprinkling ports 432, and the left and right ends of the counter branch 433 are provided with counter nozzles 434. Each counter nozzle 434 is arranged toward the middle of the chassis 1 and tilted downward. Therefore, by setting the counter nozzle 433 and the water sprinkling nozzle, the dust on the ground can be effectively washed away, and the cleaning effect in the lane can be improved. In the specific implementation, the water sprinkling port 432 on the water sprinkling branch 431 and the counter nozzle 434 on the counter branch 433 can adopt conventional water sprinkling ports 432 and nozzle structures well known to those skilled in the art, so as to achieve the washing of the ground.
