Description

Technical Field

[0001] The utility model relates to the technical field of mining vehicles, in particular to a mining explosion-proof trackless rubber-wheeled full-section cleaning vehicle. Background Art

[0002] As a complex network of carefully drilled passages between the surface and the ore body, tunnels play multiple critical roles. They serve as the primary pathways for ore transportation, ensuring efficient mining operations. They also provide crucial ventilation for the mine, ensuring the safety and health of underground personnel through air circulation. Furthermore, tunnels are responsible for drainage, effectively preventing mine flooding. Furthermore, they serve as essential routes for daily access for underground personnel and are essential for preparing for the various new excavations required for ore extraction by metallurgical equipment. However, the underground working environment is often extremely harsh, with heavy dust in the air and debris on the ground, posing a serious threat to mine safety and efficiency. Therefore, regular and thorough cleaning of tunnels is crucial for maintaining a clean mine environment and ensuring smooth production.

[0003] Traditionally, tunnel cleaning relies primarily on specialized cleaning vehicles. These vehicles use water from their tanks to flush the tunnel surface, removing dust and debris adhering to the walls. However, due to technical limitations such as the vehicle's water pressure, it's often difficult to fully clean the entire tunnel. This is especially true at the top of the tunnel, where, due to its high location, blind spots are more likely to occur, resulting in poor cleaning results. Utility Model Content

[0004] In view of this, the utility model aims to propose a mining explosion-proof trackless rubber-wheeled full-section cleaning vehicle to improve the cleaning effect of the cleaning vehicle on the tunnel.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A mining explosion-proof trackless rubber-tyred full-section cleaning vehicle, comprising:

[0007] vehicle body;

[0008] The first flushing device includes two first nozzles symmetrically arranged on both sides of the vehicle body in the width direction, and the spray direction of the first nozzles is toward the lower part of the inner wall of the tunnel;

[0009] a second flushing device comprising an extension tube capable of rotating and folding relative to the vehicle body, and a second nozzle disposed at an end of the extension tube, wherein the rotation axis of the extension tube is disposed along the width direction of the vehicle body, and when the extension tube is in an unfolded state, the spray direction of the second nozzle is toward the top of the inner wall of the roadway;

[0010] A third flushing device includes two third nozzles symmetrically arranged on both sides of the vehicle body in the width direction, and the spray direction of the third nozzles is toward the middle of the inner wall of the tunnel;

[0011] The spraying area formed by the first nozzle, the second nozzle and the third nozzle can cover the inner wall of the tunnel.

[0012] Furthermore, the second cleaning device includes an adjusting tube, which is rotatable relative to the vehicle body, with a rotating shaft arranged along the height direction of the vehicle body, and the extension tube is rotatably connected to the adjusting tube.

[0013] Furthermore, the cleaning vehicle includes a water supply main, and the regulating pipe is rotatably connected to the water supply main;

[0014] A driving device is provided between the water supply main and the regulating pipe, and between the regulating pipe and the extension pipe. The driving device can output power to drive the regulating pipe or the extension pipe to rotate.

[0015] Furthermore, the driving device includes:

[0016] A transmission member, comprising a housing and a rotating portion rotatably connected to the housing;

[0017] a hydraulic motor connected to the housing and capable of driving the rotating part to rotate;

[0018] The extension tube and the adjustment tube are both connected to the corresponding rotating parts.

[0019] Furthermore, the driving device includes a limiting part and a contact part. Two limiting parts are provided on the shell. The contact part is fixedly connected to the rotating part. The two limiting parts constitute a limit for the contact part to limit the rotatable angle of the adjusting tube or the extension tube.

[0020] Furthermore, a hydraulic valve is provided on the liquid inlet pipeline of the hydraulic motor, the limit part includes a limit switch, the limit switch is connected to an air tank, and the gas in the air tank can enter the hydraulic valve after passing through the limit switch to maintain the open state of the hydraulic valve; when the contact part touches and closes the limit switch, the limit switch cuts off the channel between the air tank and the hydraulic valve to close the hydraulic valve.

[0021] Furthermore, the rotating part is a worm gear, and the transmission member includes a worm, which is connected to the drive shaft of the hydraulic motor and meshes with the worm gear.

[0022] Furthermore, the cleaning vehicle includes a fourth flushing device, which includes two fourth nozzles arranged on both sides of the bottom end of the vehicle body. The spraying direction of the fourth nozzle is inclined downward, and the two fourth nozzles spray crosswise, and the formed spraying area can cover the tunnel ground under the vehicle body.

[0023] Furthermore, the cleaning vehicle includes a spraying device arranged at the rear end of the vehicle, and the spraying device includes two symmetrical atomizing nozzles on both sides of the width direction of the vehicle body. The spraying area formed by the two atomizing nozzles can cover the ground of the tunnel.

[0024] Furthermore, the first nozzle and / or the second nozzle and / or the third nozzle are all rotatable duckbill-shaped nozzles.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] The utility model discloses a mining explosion-proof trackless rubber-wheeled full-section cleaning vehicle, which can flush the lower part of the inner wall of the tunnel by arranging a first flushing device, can flush the top of the tunnel by arranging a second flushing device through a foldable extension pipe, and can flush the upper oblique side wall of the tunnel by arranging a third flushing device, thereby realizing full-section cleaning of the tunnel and improving the cleaning effect of the cleaning vehicle on the tunnel; at the same time, the extension pipe can be folded and retracted. When the cleaning operation is not needed, the extension pipe can be folded and retracted. The extension pipe does not exceed the top of the cleaning vehicle, which can make the extension pipe less likely to collide with obstacles above the cleaning vehicle during driving, thereby improving driving safety.

[0027] An adjusting tube is set, and the rotatable axis of the adjusting tube is perpendicular to the rotatable axis of the extension tube. When the tunnel is wide, if the second nozzle cannot completely flush the tunnel top in one time, the adjusting tube and the extension tube can be rotated in combination to tilt the second nozzle toward one side of the tunnel top, flush this side first, and then flush the other side to achieve full-section cleaning of the tunnel.

[0028] Setting up a driving device can facilitate the control of the rotation angle of the adjusting tube and the angle between the extension tube and the adjusting tube, so as to accurately adjust the spraying direction and posture of the second nozzle and improve the flushing effect of the second nozzle on the top of the tunnel.

[0029] The hydraulic motor can drive the transmission member to rotate the rotating part. In an underground environment, the hydraulic motor has a stronger tolerance than a conventional motor, does not require a stable power supply, and is not prone to overheating and failing to work.

[0030] The contact portion is configured to be able to move between the two limiting portions and to stop moving after touching the limiting portions, thereby limiting the rotation angle of the extension tube or the adjustment tube.

[0031] A hydraulic valve is provided to control the on-off of the oil circuit entering the hydraulic motor, thereby realizing rapid control of the hydraulic motor. An air storage tank and a corresponding air circuit are provided to be connected to the hydraulic valve, and the on-off of the air circuit is controlled by a limit switch, thereby realizing rapid disconnection of the hydraulic valve when the contact part touches the closed limit switch, so that the contact part is not easily damaged by excessive collision with the limit part.

[0032] Using a worm gear as the force transmission structure between the hydraulic motor and the rotating part can enable the rotating part to receive a larger torque and is not easy to get stuck during rotation. The worm gear mechanism has self-locking properties. After the worm stops rotating, the worm wheel will not rotate under the action of external force, thereby maintaining the parking position of the rotating part.

[0033] By setting two fourth nozzles at the bottom of the vehicle, the two fourth nozzles are tilted downward, and the spraying area can cover the tunnel ground, and flush the debris on the ground under the cleaning vehicle to both sides of the ground, realizing synchronous flushing of the ground and enriching the use function of the cleaning vehicle.

[0034] A spraying device is installed at the tail end of the cleaning vehicle, which can reduce dust on the road surface where the cleaning vehicle passes and reduce the spread of dust. An atomizing nozzle is installed on each side of the vehicle, which can make the sprayed water mist more uniform and fine, thereby improving the dust reduction effect.

[0035] Setting the first nozzle, the second nozzle and the third nozzle in a rotatable duckbill shape can make the sprayed water curtain fan-shaped, so that the water can cover a larger area, further making the flushing of various parts of the inner wall of the tunnel more uniform. The rotatable setting can also facilitate angle adjustment to adapt to tunnel sections of different shapes and sizes. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0064] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0065] The present embodiment relates to a mining explosion-proof trackless rubber-tyred full-section cleaning vehicle, which is used to improve the cleaning effect of the cleaning vehicle and achieve full-section cleaning of underground tunnels.

[0066] In terms of overall structure, a mining explosion-proof trackless rubber-tyred full-section cleaning vehicle in this embodiment includes a vehicle body, a first flushing device, a second flushing device and a third flushing device.

[0067] The first flushing device includes two first nozzles symmetrically arranged on both sides of the vehicle body in the width direction, and the spraying direction of the first nozzles is toward the lower part of the inner wall of the tunnel.

[0068] The second flushing device includes an extension tube that can be rotated and folded relative to the vehicle body, and a second nozzle arranged at the end of the extension tube. The rotation axis of the extension tube is arranged along the width direction of the vehicle body. When the extension tube is in the unfolded state, the spraying direction of the second nozzle is toward the top of the inner wall of the tunnel.

[0069] The third flushing device includes two third nozzles symmetrically arranged on both sides of the vehicle body in the width direction, and the spraying direction of the third nozzles is toward the middle of the inner wall of the tunnel.

[0070] The spraying area formed by the first nozzle, the second nozzle and the third nozzle can cover the inner wall of the tunnel.

[0071] As configured above, a mining explosion-proof trackless rubber-tyred full-section cleaning vehicle of this embodiment can flush the lower part of the inner wall of the tunnel by setting a first flushing device, and can flush the top of the tunnel through a foldable extension pipe by setting a second flushing device, with low requirements for water pressure. The third flushing device can flush the upper oblique side wall of the tunnel, thereby achieving full-section cleaning of the tunnel and improving the cleaning effect of the cleaning vehicle on the tunnel; at the same time, the extension pipe can be folded and retracted. When cleaning operations are not required, the extension pipe can be folded and retracted. The extension pipe does not exceed the top of the cleaning vehicle, which can make the extension pipe less likely to collide with obstacles above the cleaning vehicle during driving, thereby improving driving safety.

[0072] Based on the above overall introduction, refer to Figures 1 to 4 As shown, specifically, the first flushing device 2, the second flushing device 3, and the third flushing device 4 of this embodiment are all arranged at the rear end of the vehicle body 1, so that after the first flushing device 2, the second flushing device 3, and the third flushing device 4 have flushed the inner wall of the lane, the sewage on the inner wall of the lane is not easy to fall onto the cleaning vehicle. The spray direction of the first nozzle 201 is horizontal spray in the Y direction. After the extension tube 302 is unfolded, the spray direction of the second nozzle 301 is vertically upward, and the spray direction of the third nozzle 401 is inclined upward, forming a forty-five degree angle with the spray direction of the first nozzle 201. The first nozzle 201, the second nozzle 301, and the third nozzle 401 can simultaneously flush the inner wall of the lane, which can meet the cleaning needs of both rectangular cross-section lanes and arch-shaped cross-section lanes. The cleaning vehicle of this embodiment is a trackless rubber-wheel cleaning vehicle. At the same time, all parts on the vehicle are explosion-proof parts, which have good safety in use.

[0073] Secondly, to meet the cleaning needs of wider lanes, the second cleaning device includes an adjustment tube 303, which can rotate relative to the vehicle body 1. The rotation axis is set along the height direction of the vehicle body 1, and the extension tube 302 is rotatably connected to the adjustment tube 303. The adjustment tube 303 is set so that the rotation axis of the adjustment tube 303 is perpendicular to the rotation axis of the extension tube 302. When the lane is wide, if the second nozzle 301 cannot completely flush the top of the lane in a single shot, the second nozzle 301 can be tilted toward one side of the top of the lane by rotating the adjustment tube 303 and the extension tube 302 in combination, and then flushing the other side, so as to achieve full-section cleaning of the lane.

[0074] As a preferred embodiment, the extension tube 302 of this embodiment is L-shaped, with one end pivotally connected to the adjustment tube 303, and the other end capable of folding up and down due to its own rotation. One end of the adjustment tube 303 is vertically downward, while the other end is bent horizontally and then forms a U-shaped bend at the bend, aligning the central axis of the connection between the adjustment tube 303 and the extension tube 302 to a horizontal position. This arrangement also allows the extension tube 302 to be positioned more centrally relative to the rear end of the vehicle body 1, providing greater coverage for flushing the top of the roadway.

[0075] Regarding the water supply method for the cleaning vehicle, the cleaning vehicle of this embodiment includes a water supply main 5, to which the regulating pipe 303 is rotatably connected. A drive device 6 is provided between the water supply main 5 and the regulating pipe 303, and between the regulating pipe 303 and the extension pipe 302. The drive device 6 can output power to drive the regulating pipe 303 or the extension pipe 302 to rotate. The provision of the drive device 6 facilitates control of the rotation angle of the regulating pipe 303 and the angle between the extension pipe 302 and the regulating pipe 303, thereby facilitating accurate adjustment of the spray direction and posture of the second nozzle 301, thereby enhancing the flushing effect of the second nozzle 301 on the top of the tunnel.

[0076] Specifically, the drive device 6 includes a transmission member 602 and a hydraulic motor 601. The transmission member 602 includes a housing 6021 and a rotating portion 6022 rotatably connected to the housing 6021. The hydraulic motor 601 is connected to the housing 6021 and can drive the rotating portion 6022 to rotate. The extension tube 302 and the adjustment tube 303 are both connected to the corresponding rotating portion 6022. The hydraulic motor 601 can drive the transmission member 602 to rotate the rotating portion 6022. In an underground environment, the hydraulic motor 601 has a stronger tolerance than conventional motors, does not require a stable power supply, and is not prone to overheating and failing to work. At the same time, the cleaning vehicle usually also has its own hydraulic system. Therefore, the power source of the drive device 6 is preferably the hydraulic motor 601.

[0077] To prevent excessive rotation of the extension tube 302 or the adjustment tube 303, the drive device 6 includes a limiting portion 603 and a contact portion 604. Two limiting portions 603 are provided on the housing 6021. The contact portion 604 is fixedly connected to the rotation portion 6022. The two limiting portions 603 limit the contact portion 604 to limit the rotation angle of the adjustment tube 303 or the extension tube 302. The contact portion 604 is configured to move between the two limiting portions 603 and stop moving after contacting the limiting portion 603. This limits the rotation angle of the extension tube 302 or the adjustment tube 303, preventing the extension tube 302 or the adjustment tube 303 from excessive rotation and colliding with the vehicle body 1 or other objects.

[0078] Further, refer to Figures 3 to 5As shown, a hydraulic valve 7 is provided on the inlet pipeline of the hydraulic motor 601. The limiting portion 603 includes a limit switch 6031. The limit switch 6031 is connected to an air tank 8. Gas in the air tank 8 can enter the hydraulic valve 7 after passing through the limit switch 6031, thereby maintaining the hydraulic valve 7 in an open state. When the contact portion 604 touches and closes the limit switch 6031, the limit switch 6031 cuts off the passage between the air tank 8 and the hydraulic valve 7. The hydraulic valve 7 is provided with a spring, which automatically closes the hydraulic valve 7 under the action of the spring. The provision of the hydraulic valve 7 can control the flow of oil into the hydraulic motor 601, thereby achieving rapid control of the hydraulic motor 601. The provision of the air tank 8 and the corresponding air path connected to the hydraulic valve 7, and the air path is controlled by the limit switch 6031, can achieve rapid opening of the hydraulic valve 7 when the contact portion 604 touches and closes the limit switch 6031, thereby preventing the contact portion 604 from excessively impacting the limiting portion 603 and causing damage to the limiting portion 603.

[0079] It should be noted that the limiting portion 603 can also be set as a limiting block fixed to the housing 6021, and the rotation stops when the contact block abuts the limiting block. However, this limiting method may cause the contact block to excessively collide with the limiting block, generating large vibrations, and the limiting block is also easily damaged, which is not as good as the limiting method of this embodiment. The limiting portion 603 located between the extension tube 302 and the regulating tube 303 is used to limit the rotation of the extension tube 302 so that the extension tube 302 does not collide with the top of the vehicle body 1 when it is unfolded, and does not collide with the middle of the vehicle body 1 when the extension tube 302 is folded. The limiting portion 603 located between the regulating tube 303 and the water supply main 5 can limit the rotation of the regulating tube 303 so that the regulating tube 303 does not collide with the vehicle body 1 when it rotates, and the corresponding extension tube 302 and the drive device 6 will not collide with the vehicle body 1, thereby preventing damage.

[0080] For the specific structure of the driving device 6, refer to Figure 3 and Figure 4 As shown, in this embodiment, the rotating portion 6022 is a worm gear, and the transmission member 602 includes a worm, which is connected to the drive shaft of the hydraulic motor 601 and meshes with the worm gear. The use of a worm gear as the force transmission structure between the hydraulic motor 601 and the rotating portion 6022 enables the rotating portion 6022 to receive a large torque, which is less likely to cause jamming during rotation. Furthermore, the worm gear mechanism is self-locking. After the worm gear stops rotating, the worm gear will not rotate under the influence of external forces, thereby maintaining the idle position of the rotating portion 6022. This ensures that the position of the second nozzle 301 remains unchanged and the spray angle is fixed while the cleaning vehicle is in motion.

[0081] In specific implementation, refer to Figure 5As shown, the hydraulic circuit (black circuit) and the air circuit (red circuit) cooperate as follows: manually closing the air valve 11 allows gas to enter the hydraulic valve 7, opening it and starting the hydraulic pump. By adjusting the hydraulic valve 7, the corresponding hydraulic motor 601 can be controlled to rotate forward and reverse, positioning the second nozzle 301 in the desired position. When the contact portion 604 triggers the limit switch 6031, the limit switch 6031 disconnects the air circuit, and the hydraulic valve 7 quickly closes under the elastic force of its own spring, severing the hydraulic oil circuit of the corresponding hydraulic motor 601 and quickly shutting down the hydraulic pump. Specifically, the hydraulic valve 7 is a 3-position, 6-way valve, the limit switch 6031 is a 2-position, 5-way valve, and the air valve 11 is a 3-position, 5-way valve.

[0082] For the purpose of cleaning the roadway surface, the cleaning vehicle includes a fourth flushing device 9, which includes two fourth nozzles 901 arranged on both sides of the bottom end of the vehicle body 1. The spray direction of the fourth nozzles 901 is inclined downward. The two fourth nozzles 901 spray in a cross-spraying manner, and the formed spray area can cover the roadway surface below the vehicle body 1. By arranging two fourth nozzles 901 at the bottom of the vehicle, the two fourth nozzles 901 are inclined downward, and the spray area can cover the roadway surface, and the debris on the ground below the cleaning vehicle is flushed to both sides of the ground, achieving synchronous flushing of the ground, enriching the use function of the cleaning vehicle.

[0083] During implementation, the movement of the cleaning vehicle and the flushing of the various flushing devices may generate dust. To suppress this dust, the cleaning vehicle of this embodiment includes a spraying device 10 disposed at the rear end of the vehicle. The spraying device 10 includes two symmetrical atomizing nozzles 1001 on either side of the vehicle body 1 in the width direction. The spraying area formed by the two atomizing nozzles 1001 can cover the ground surface of the roadway. The spraying device 10 is installed at the rear end of the cleaning vehicle to reduce dust on the road surface that the cleaning vehicle passes through, reducing dust diffusion. The installation of an atomizing nozzle 1001 on each side of the vehicle can make the sprayed water mist more uniform and fine, thereby improving the dust reduction effect.

[0084] Regarding the specific structure of each nozzle, the first nozzle 201 and / or the second nozzle 301 and / or the third nozzle 401 are all rotatable duckbill nozzles. Arranging the first nozzle 201, the second nozzle 301, and the third nozzle 401 in a rotatable duckbill shape allows the sprayed water curtain to form a fan shape, allowing the water to cover a larger area and further ensuring more uniform flushing of various parts of the tunnel inner wall. The rotatable arrangement also facilitates angle adjustment to accommodate tunnel cross-sections of varying shapes and sizes. The first nozzle 201, the second nozzle 301, and the third nozzle 401 of this embodiment are all rotatable duckbill nozzles.

[0085] The explosion-proof, trackless, rubber-tyred, full-section cleaning vehicle for mining of this embodiment is capable of performing full-section cleaning of a roadway by providing a first flushing device 2, a second flushing device 3, and a third flushing device 4, thereby improving the cleaning effect of the cleaning vehicle on the roadway. Furthermore, the extension tube 302 is foldable and retractable. When cleaning operations are not required, the extension tube 302 can be folded and retracted, making it less likely to collide with obstacles above the cleaning vehicle during travel, thereby improving travel safety. The provision of a limiting portion 603 can limit the extension tube 302 and the adjustment tube 303, preventing them from excessively rotating and colliding with the vehicle body 1 or other objects, thereby causing damage.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
