Description

Technical Field

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

[0002] As a complex network of passages carefully drilled between the surface and the ore body, tunnels play multiple key roles. They are not only the main channels for ore transportation, ensuring the efficient operation of mining operations; at the same time, they also undertake the important task of mine ventilation, ensuring the safety and health of underground personnel through air circulation; in addition, tunnels are also responsible for drainage operations, effectively preventing the occurrence of mine floods; and they are also the only way for underground personnel to enter and exit daily, as well as necessary preparations for various new excavation projects required for metallurgical equipment to mine ore. However, the working environment underground is often extremely harsh, with a large amount of dust in the air and various debris scattered on the ground, all of which pose a serious threat to the safe production and operating efficiency of the mine. Therefore, regular and thorough cleaning of the tunnels has become an important part of maintaining a clean mine environment and ensuring smooth production.

[0003] Traditional tunnel cleaning work mainly relies on professional cleaning vehicles. These cleaning vehicles use the water carried by their own water tanks to flush the tunnel surface and wash away the dust and debris attached to the tunnel wall. However, due to the limitations of technical conditions such as the water pressure of the cleaning vehicle, it is often difficult to achieve a complete cleaning of the entire tunnel section without dead angles, especially in the top area of ​​the tunnel. Due to its high position, it is more likely to have cleaning dead angles and poor cleaning effect. Summary of the invention

[0004] In view of this, the present invention aims to provide a mining explosion-proof trackless rubber-tyred full-section cleaning vehicle to improve the cleaning effect of the cleaning vehicle on the tunnel.

[0005] To achieve the above object, the technical solution of the present invention 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 comprises 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 lane;

[0009] The second flushing device comprises 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, wherein the rotation axis of the extension tube is arranged along the width direction of the vehicle body, and when the extension tube is in the unfolded state, the spray direction of the second nozzle is toward the top of the inner wall of the tunnel;

[0010] A third flushing device comprises 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 lane;

[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, the adjusting tube can rotate relative to the vehicle body, the rotating shaft is 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 comprises 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 pipe 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 comprises:

[0016] A transmission member, comprising a housing and a rotating part 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 portion and a contact portion, two limiting portions are provided on the shell, the contact portion is fixedly connected to the rotating portion, and the two limiting portions constitute a limit for the contact portion 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, and the limit part includes a limit switch, which is connected to an air storage tank. The gas in the air storage 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 storage 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, and the worm is connected to the driving 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 lane.

[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 explosion-proof trackless rubber-tyred full-section cleaning vehicle for mining described in the present invention 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 oblique upper side wall of the tunnel by arranging a third flushing device, 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 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, so that the extension pipe is not easy to collide with obstacles located above the cleaning vehicle during driving, thereby improving driving safety.

[0027] An adjusting tube is provided, 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 at one time, the adjusting tube and the extension tube can be coordinated and rotated to tilt the second nozzle toward one side of the tunnel top, and this side is flushed first, and then the other side is flushed, so as to achieve full-section cleaning of the tunnel.

[0028] The drive device can be provided to facilitate 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 spray direction and posture of the second nozzle and enhance 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 arranged to be able to move between the two limiting portions, and to stop moving after touching the limiting portions, thereby achieving the limitation of the rotation angle of the extension tube or the adjustment tube.

[0031] A hydraulic valve is provided to control the on-and-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-and-off of the air circuit is controlled by a limit switch. This enables 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 arranging 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 the debris on the ground under the cleaning vehicle can be flushed to both sides of the ground, thereby realizing synchronous flushing of the ground and enriching the use function of the cleaning vehicle.

[0034] A spraying device is installed at the rear 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 dense, 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

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.

[0064] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction 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 comprises two first nozzles which are 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 nozzle 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 the present embodiment can flush the lower part of the inner wall of the tunnel by arranging a first flushing device, and can flush the top of the tunnel through a foldable extension pipe by arranging a second flushing device, with low requirements for water pressure, and can flush the upper oblique side wall of the tunnel by arranging a third flushing device, 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, so that the extension pipe is not easy to collide with obstacles located 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 on 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 45-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 flush the inner wall of the lane at the same time, which can meet the cleaning of the rectangular cross-section lane and the arch-shaped cross-section lane. The cleaning vehicle of this embodiment is a trackless rubber wheel cleaning vehicle, and all the parts on the vehicle are explosion-proof parts, which has good safety in use.

[0073] Secondly, in order to meet the cleaning requirements for lanes with a larger width, the second cleaning device includes an adjusting pipe 303, which can rotate relative to the vehicle body 1, and the rotating shaft is arranged along the height direction of the vehicle body 1, and the extension pipe 302 is rotatably connected to the adjusting pipe 303. The adjusting pipe 303 is arranged, and the rotatable shaft of the adjusting pipe 303 is perpendicular to the rotatable shaft of the extension pipe 302. When the lane is wider, if the second nozzle 301 cannot completely wash the top of the lane in a single time, the second nozzle 301 can be tilted toward one side of the top of the lane by rotating the adjusting pipe 303 and the extension pipe 302, and the side is first washed, and then the other side is washed, 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, one end of which is rotatably connected to the adjustment tube 303, and the other end can be rotated and folded up and down due to its own rotation. One end of the adjustment tube 303 is vertically downward, and the other end is horizontally bent and then U-shaped at the bend, so that the central axis of the connection end of the adjustment tube 303 and the extension tube 302 is adjusted to a horizontal state. Such an arrangement can also make the position of the extension tube 302 relatively centered relative to the rear end of the vehicle body 1, and the flushing coverage area of ​​the top of the lane is larger.

[0075] As for the water supply method of the cleaning vehicle, the cleaning vehicle of this embodiment includes a water supply main pipe 5, and the regulating pipe 303 is rotatably connected to the water supply main pipe 5. A driving device 6 is provided between the water supply main pipe 5 and the regulating pipe 303, and between the regulating pipe 303 and the extension pipe 302. The driving device 6 can output power to drive the regulating pipe 303 or the extension pipe 302 to rotate. The provision of the driving device 6 can facilitate the control of the rotation angle of the regulating pipe 303 and the angle between the extension pipe 302 and the regulating pipe 303, so as to accurately adjust the spray direction and posture of the second nozzle 301, and improve 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 being unable to work. At the same time, the cleaning vehicle usually also has its own hydraulic system, so the power source of the drive device 6 is preferably the hydraulic motor 601.

[0077] In order to prevent the extension tube 302 or the adjustment tube 303 from excessively rotating, the driving 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 rotating portion 6022. The two limiting portions 603 constitute a limit for the contact portion 604 to limit the rotation angle of the adjustment tube 303 or the extension tube 302. The contact portion 604 is arranged to be movable between the two limiting portions 603 and stops moving after touching the limiting portion 603, so as to limit the rotation angle of the extension tube 302 or the adjustment tube 303, so that the extension tube 302 or the adjustment tube 303 is not easy to excessively rotate and collide with the vehicle body 1 or other objects.

[0078] Further, see Figures 3 to 5As shown, a hydraulic valve 7 is provided on the liquid inlet pipeline of the hydraulic motor 601, and the limit part 603 includes a limit switch 6031. The limit switch 6031 is connected to the gas tank 8. The gas in the gas tank 8 can enter the hydraulic valve 7 after passing through the limit switch 6031 to keep the hydraulic valve 7 open; when the contact part 604 touches the closed limit switch 6031, the limit switch 6031 cuts off the passage between the gas tank 8 and the hydraulic valve 7. A spring is provided in the hydraulic valve 7. Under the action of the spring, the hydraulic valve 7 can be automatically closed. The hydraulic valve 7 is provided to control the on-off of the oil circuit entering the hydraulic motor 601, so as to realize the rapid control of the hydraulic motor 601. The gas tank 8 and the corresponding gas circuit are connected to the hydraulic valve 7, and the on-off of the gas circuit is controlled by the limit switch 6031. The rapid disconnection of the hydraulic valve 7 can be realized when the contact part 604 touches the closed limit switch 6031, so that the contact part 604 is not easy to excessively collide with the limit part 603 to cause damage to the limit part 603.

[0079] It should be noted that the limiting portion 603 can also be set as a limiting block fixed on the shell 6021, and the rotation stops when the contact block abuts the limiting block. However, in this limiting method, the contact block may excessively collide with the limiting block, resulting in greater vibration, 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 adjustment 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 after the extension tube 302 is folded. The limiting portion 603 located between the adjustment tube 303 and the water supply main 5 can limit the rotation of the adjustment tube 303, so that the adjustment 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 to prevent damage.

[0080] For the specific structure of the driving device 6, refer to Figure 3 and Figure 4 As shown, the rotating part 6022 of this embodiment is a worm gear, and the transmission part 602 includes a worm, which is connected to the driving shaft of the hydraulic motor 601 and meshes with the worm gear. The use of worm gears as the force transmission structure of the hydraulic motor 601 and the rotating part 6022 can make the rotating part 6022 receive a large torque, and it is not easy to get stuck when rotating. The worm gear mechanism has self-locking properties. After the worm gear stops rotating, the worm gear will not rotate under the action of external force, thereby maintaining the parking position of the rotating part 6022, so that the position of the second nozzle 301 remains unchanged and the spray angle is fixed during the driving process of the cleaning vehicle.

[0081] In specific implementation, refer to Figure 5As shown, the coordination mode of the hydraulic circuit (black circuit) and the gas circuit (red circuit) is as follows: the gas valve 11 is manually closed, the gas enters the hydraulic valve 7 to open the hydraulic valve 7, and the hydraulic pump is started. By adjusting the hydraulic valve 7, the corresponding hydraulic motor 601 can be controlled to rotate forward and reverse, so that the second nozzle 301 is in the required position. When the contact part 604 triggers the limit switch 6031, the limit switch 6031 disconnects the gas circuit, and the hydraulic valve 7 is quickly closed under the elastic force of its own spring, which can cut off the hydraulic oil circuit of the corresponding hydraulic motor 601 and realize the rapid shutdown of the hydraulic pump. Among them, the hydraulic valve 7 is a three-position six-way valve, the limit switch 6031 is a two-position five-way valve, and the gas valve 11 is a three-position five-way valve.

[0082] For the purpose of cleaning the roadway floor, the cleaning vehicle includes a fourth flushing device 9, which includes two fourth nozzles 901 arranged on both sides of the bottom of the vehicle body 1. The spraying direction of the fourth nozzle 901 is inclined downward, and the two fourth nozzles 901 spray crosswise, and the formed spraying area can cover the roadway floor under 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 spraying area can cover the roadway floor, and the debris on the ground under the cleaning vehicle is flushed to both sides of the ground, so as to achieve synchronous flushing of the ground, and enrich the use function of the cleaning vehicle.

[0083] In specific implementation, the driving of the cleaning vehicle and the flushing of each flushing device may generate dust. In order to suppress dust, the cleaning vehicle of this embodiment includes a spraying device 10 arranged at the rear end of the vehicle. The spraying device 10 includes two symmetrical atomizing nozzles 1001 on both sides of the width direction of the vehicle body 1. The spraying area formed by the two atomizing nozzles 1001 can cover the ground of the lane. The spraying device 10 is arranged at the rear 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 1001 is arranged on each side of the vehicle, which can make the sprayed water mist more uniform and fine, and improve the dust reduction effect.

[0084] As for 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. The first nozzle 201, the second nozzle 301, and the third nozzle 401 are set to be rotatable duckbill shape, so that the sprayed water curtain can be fan-shaped, so that the water can cover a larger area, and further make the flushing of various parts of the inner wall of the tunnel more uniform. The rotatable setting method can also facilitate angle adjustment to adapt to tunnel sections of different 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 can clean the full section of the tunnel by providing the first flushing device 2, the second flushing device 3 and the third flushing device 4, thereby improving the cleaning effect of the cleaning vehicle on the tunnel. At the same time, the extension tube 302 can be folded and retracted. When the cleaning operation is not needed, the extension tube 302 can be folded and retracted, which is not easy to collide with obstacles above the cleaning vehicle during driving, thereby improving driving safety. The limiting part 603 is provided to limit the extension tube 302 and the adjusting tube 303, so that the extension tube 302 and the adjusting tube 303 are not easy to rotate excessively and collide with the vehicle body 1 or other objects to cause 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 substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
