Description

Technical Field

[0001] The invention belongs to the technical field of tunnel dust removal, and in particular relates to a large-scale dust removal equipment for tunnels. Background Art

[0002] Tunnels are engineering buildings buried in the ground. They are a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels and mining tunnels. Many cables, wires, lighting and other facilities are installed in the tunnels. Some dust will be generated during the driving of vehicles. These dusts will adhere to the surface of the facilities in the tunnel or the inner wall of the tunnel. As time goes by, the dust will accumulate thicker and thicker, which will not only pollute the environment of the tunnel, but also the dust raised during driving will adhere to the surface of the vehicle, affecting the appearance of the vehicle and the normal operation of the electronic monitoring and safety equipment in the tunnel.

[0003] In the prior art, water guns are usually used to remove dust from tunnels. However, this method has a drawback that manual dust removal with water guns consumes a lot of physical strength, which not only has low work efficiency, but also easily leads to missed areas.

[0004] At the same time, when the water gun is performing dust removal work, the water gun sometimes cannot spray to a distant place due to insufficient pressure, thereby making the dust removal effect worse. At this time, it is necessary to adjust the position of the water gun to achieve a better dust removal effect. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a large-scale dust removal equipment for tunnels.

[0006] The technical solution adopted to solve the above technical problems is: a large-scale dust removal equipment for tunnels, including a base plate, universal wheels are fixedly connected to the four corners of the lower surface of the base plate, a lifting mechanism is arranged above the outside of the base plate, a mounting plate is arranged above the outside of the lifting mechanism, a water tank is arranged above the outside of the mounting plate, a first cleaning mechanism is arranged on one side of the outside of the water tank, a second cleaning mechanism is arranged on the outside of the water tank at an end away from the first cleaning mechanism, the first cleaning mechanism and the second cleaning mechanism cooperate with each other to clean the tunnel arc top, and the lifting mechanism drives the first cleaning mechanism and the second cleaning mechanism to move up and down.

[0007] Through the above technical solution, the first cleaning mechanism and the second cleaning mechanism will spray cleaning liquid to remove dust and clean the inside of the tunnel. When the impact force of the first cleaning mechanism and the second cleaning mechanism cannot achieve the cleaning effect, the lifting mechanism will drive the first cleaning mechanism and the second cleaning mechanism to rise or fall, thereby performing close-range spraying to complete the cleaning work.

[0008] Furthermore, the lifting mechanism includes a fixed block fixedly connected to one side of the upper surface of the base plate, the fixed block is located at the front end and the rear end of the upper surface of the base plate, the front end and the rear end of the upper surface of the base plate are fixedly connected to a fixed bar, and a slider is provided on the side of the upper surface of the base plate away from the fixed block, the slider is located inside the fixed bar, and the slider slides inside the fixed bar.

[0009] Through the above technical solution, the slider will slide inside the fixed bar, thereby shortening the distance between the fixed block and the slider, and then raising the height position of the mounting plate through other structures inside the lifting mechanism. When the distance between the fixed block and the slider increases, the height position of the mounting plate will be lowered.

[0010] Furthermore, the lifting mechanism also includes a fixed block fixedly connected to one side of the lower surface of the mounting plate, the fixed block is located at the front end and the rear end of the lower surface of the base plate, the front end and the rear end of the lower surface of the base plate are fixedly connected with a fixed bar, and a slider is provided on the lower surface of the mounting plate on the side away from the fixed block, the slider is located inside the fixed bar, and the slider slides inside the fixed bar, and the fixed block and slider on the lower surface of the mounting plate correspond to the fixed block and slider on the upper surface of the base plate.

[0011] Through the above technical solution, it can be known that the lifting mechanism connects the bottom plate and the mounting plate, and the lifting mechanism can increase or decrease the distance between the bottom plate and the mounting plate, thereby achieving the effect of adjusting the height of the first cleaning mechanism and the second cleaning mechanism.

[0012] Furthermore, the lifting mechanism also includes a support rod connected to the fixed block and the slider, the two ends of the support rod are respectively connected to the fixed block and the slider, the support rod is located on both sides of the fixed block and the slider, and the support rods on both sides are cross-arranged, an axle rod is provided in the middle of the inside of the support rod, a guide rope block is fixedly provided in the middle of the outside of the axle rod, a winch is fixedly connected to the middle of one side of the outer lower surface of the mounting plate, a fixed shaft is fixedly connected to the middle of one side of the outer upper surface of the base plate, the winch and the fixed shaft are located on the same side, a winding rope is wound around the outside of the winch, and the winding rope is located outside the guide rope block and connected to the fixed shaft.

[0013] Through the above technical solution, one end of the winding rope is fixedly connected to the fixed shaft, so that when the winch is running, the winding rope will be retracted. When the winding rope is retracted, the shaft rod will be pulled through the guide rope block. When the shaft rod moves, the slider connected to it moves, thereby achieving the effect of raising and lowering the height of the first cleaning mechanism and the second cleaning mechanism.

[0014] Furthermore, the first cleaning mechanism includes a first support plate arranged on one side of the upper surface of the mounting plate, a rod hole is opened inside the first support plate, a first water spray gun is arranged on the surface of the first support plate on the side away from the water tank, a first turntable is arranged above the first support plate on the side close to the first water spray gun, a sleeve is arranged inside the first turntable, a receiving ring is arranged at the lower part of the first support plate, the first water spray gun is located inside the sleeve and the receiving ring, the first water spray gun is connected to the water tank, the receiving ring and the sleeve are both installed through a connecting rod and the rod hole, and a block is fixedly connected to the end of the connecting rod.

[0015] Through the above technical solution, the first water spray gun is located at one end of the receiving ring and will remain basically fixed, while the end where the ring is located will move back and forth outside the first water spray gun due to the rotation of the first turntable, and while moving, it will drive the first water spray gun to swing back and forth horizontally, so that the movement process of the first water spray gun is to start from a vertical upward state, and then swing slightly toward both sides to spray water.

[0016] Furthermore, the first turntable is fixedly connected to a connecting rod on the side close to the first support plate, and the other end of the connecting rod is fixedly connected to a linkage gear. The linkage gear and the first turntable are respectively located on both sides of the first support plate. The linkage gear is provided with a first motor on the side close to the water tank, and the output end of the first motor is connected to the linkage gear.

[0017] Through the above technical solution, when the first motor is running, it will jointly drive the first turntable and the linkage gear to rotate.

[0018] Furthermore, the first cleaning mechanism also includes two second water spray guns provided on a side surface of the first support plate close to the water tank, the two second water spray guns are respectively located at the front end and the rear end of the first support plate, the front end and the rear end above the first support plate are respectively provided with side turntables, the side turntables are meshed with linkage gears, the side turntables are installed inside the first support plate through connecting rods, the inside of the side turntables are installed with rings through connecting rods, the front end and the rear end below the first support plate are provided with receiving rings, the receiving rings are installed inside the first support plate through connecting rods, the second water spray guns are located inside the receiving rings and the rings outside the side turntables, and the second water spray guns are connected to the water tank.

[0019] Through the above technical solution, when the linkage gear rotates, it will drive the side turntables on both sides to rotate, and the side turntables will drive the sleeve ring to move during the rotation. Similarly, the second water spray gun is similar to the first water spray gun, and the end where the receiving ring is located basically remains stationary, and the end where the sleeve ring is located swings, but the spray angle of the second water spray gun is different from the spray angle of the first water spray gun and the spray coverage area is different.

[0020] Furthermore, the second cleaning mechanism includes a second support plate arranged on one side of the upper surface of the mounting plate, the second support plate and the first support plate are located on both sides of the water tank, a support turntable is arranged at the lower end inside the second support plate, the second support plate is fixedly connected with a slide rail above the surface of the side close to the water tank, a lifting block is arranged on the surface of the second support plate on the side close to the water tank, a slot is provided on the surface of the lifting block, the lifting block is engaged with the surface of the slide rail through the slot, the support turntable and the lifting block are connected by a support rod, and a second motor is arranged on the surface of the support turntable on the side away from the support rod, and the output end of the second motor is fixedly connected to the support turntable.

[0022] Through the above technical scheme, the second motor will drive the supporting turntable to rotate, and the supporting turntable will drive the lifting block to move through the supporting rod during the rotation process, and the lifting block will move up and down outside the slide rail. At the same time, when the lifting block moves, it will drive the receiving ring connected to it to move up and down, so that the third water spray gun will keep the end where the ring is located basically motionless, while the end where the receiving ring is located will swing up and down, so that the third water spray gun will spray at different angles, and the spraying angle and spraying range of the third water spray gun are different from those of the second water spray gun and the first water spray gun. In this way, the two cleaning mechanisms cooperate with each other to perform dust removal work over a wider range and angle.

[0023] The beneficial effects of the present invention are as follows: (1) The present invention can perform dust removal and cleaning work on the top of the inner wall of the tunnel by setting the first cleaning mechanism and the second cleaning mechanism, and the cleaning position of each mechanism of the first cleaning mechanism and the second cleaning mechanism is different. In this way, with the cooperation of the first cleaning mechanism and the second cleaning mechanism, the inside of the tunnel can be more fully dusted and cleaned; (2) The present invention performs dust removal and cleaning by the method of water flow impact. On the one hand, the inside of the tunnel can be impacted and dusted according to the impact force of the water flow.

The receiving ring 106 and the ring 110 are installed with the rod hole 407 through the connecting rod 109, and the end of the connecting rod 109 is fixedly connected with a stopper 108, so that the connecting rod 109 will not fall out from the rod hole 407.

[0041] The first turntable 103 is fixedly connected with a connecting rod 109 on the side close to the first support plate 105, and the other end of the connecting rod 109 is fixedly connected with a linkage gear 112. The linkage gear 112 and the first turntable 103 are respectively located on both sides of the first support plate 105. The linkage gear 112 is provided with a first motor 111 on the side close to the water tank 101. The output end of the first motor 111 is connected to the linkage gear 112, so that when the first motor 111 drives the linkage gear 112 to rotate, the first turntable 103 will also rotate together.

[0042] The first cleaning mechanism 100 also includes a first support plate 105, on the side surface of which is close to the water tank 101, two second water spray guns 102 are arranged, the two second water spray guns 102 are respectively located at the front end and the rear end of the first support plate 105, and the front end and the rear end above the first support plate 105 are respectively provided with side turntables 107, and the side turntables 107 are meshed with the linkage gear 112, so that when the linkage gear 112 rotates, it will drive the side turntables 107 to rotate, and the side turntables 107 are installed inside the first support plate 105 through the connecting rod 109, and the side turntables 107 are arranged inside the first support plate 105.

[0043] like Figure 1 - Figure 2 , Figure 5 - Figure 7 As shown, the second cleaning mechanism 400 includes a second support plate 401 disposed on one side of the upper surface of the mounting plate 206, the second support plate 401 and the first support plate 105 are located on both sides of the water storage tank 101, a support turntable 404 is disposed at the lower end of the second support plate 401, a slide rail 406 is fixedly connected to the second support plate 401 above the surface of the side close to the water storage tank 101, and a lifting block 403 is disposed on the surface of the second support plate 401 close to the water storage tank 101, and a card slot 404 is provided on the surface of the lifting block 403. 08.

The support turntable 404 is provided with a second motor 409 on the side surface away from the support rod 405. The output end of the second motor 409 is fixedly connected to the support turntable 404. The second motor 409 drives the support turntable 404 to rotate. When the support turntable 404 rotates, it drives the lifting block 403 to move through the support rod 405.

[0044] The second cleaning mechanism 400 also includes a second support plate 401, and a third water spray gun 402 is provided at the front end and the rear end of the surface of one side close to the water tank 101. Rings 110 are provided at both ends of the upper part of the second support plate 401, and receiving rings 106 are provided on both sides of the lifting block 403. The third water spray gun 402 is located between the ring 110 and the receiving ring 106 inside the lifting block 403. The third water spray gun 402 is connected to the water tank 101, so that the third water spray gun 402 can draw dust removal liquid inside the water tank 101 to perform spray dust removal work.

[0045] The working principle of this embodiment is as follows: when the present invention is used for dust removal, the inside of the water tank 101 is first filled with dust removal liquid, and then the universal wheel 301 is used to drive the entire device to move;

[0046] When the present invention is in the process of moving, the first motor 111 is started first, and then the second motor 409 is started, and the moving direction of the present invention is that the first cleaning mechanism 100 is in front and the second cleaning mechanism 400 is in the back;

[0047] When the first motor 111 is started, the linkage gear 112 and the first rotating disk 103 connected thereto are driven to rotate together, and the first rotating disk 103 drives the collar 110 to rotate together during the rotation process, and the first water spray gun 104 inside the collar 110 is also driven to move, and the first water spray gun 104 uses the end where the receiving ring 106 is located as a fulcrum to swing left and right, and at the same time, the dust removal liquid is sprayed out from the first water spray gun 104;

[0048] When the linkage gear 112 rotates, the side rotating disc 107 meshing therewith will rotate, and the side rotating disc 107 will also drive the inner ring 110 to rotate during the rotation process. The second water spray gun 102 located on the surface of the side rotating disc 107 is placed inside the ring 110, and the second water spray gun 102 also swings left and right with the end where the receiving ring 106 is located as the fulcrum. The first water spray gun 104 and the second water spray gun 102 have different swing angles, so they have different cleaning areas.

[0049] When the second motor 409 is started, the second motor 409 drives the support turntable 404 to rotate. During the rotation of the support turntable 404, the lifting block 403 is driven to move through the support rod 405. Since the lifting block 403 is restricted by the slide rail 406, the lifting block 403 can only move up and down along the slide rail 406. During the up and down movement of the lifting block 403 outside the slide rail 406, the receiving ring 106 is driven to move up and down, and the third water spray gun 402 inside the receiving ring 106 is driven to move, and the third water spray gun 402 swings with the end of the ring 110 as the fulcrum, and the swing amplitude of the third water spray gun 402 is different from the swing angle of the second water spray gun 102, so as to further increase the cleaning area;

[0050] Therefore, when the first water spray gun 104 swings on the vertical top surface to spray liquid for dust removal, the second water spray gun 102 will also swing on both sides to spray liquid for dust removal, and the third water spray gun 402 at the rear will also swing on both sides to spray liquid for dust removal. The impact force of the dust removal liquid will first impact the dust on the inner wall of the tunnel, and secondly. The dust removal liquid will clean the surface of the inner wall of the tunnel, and clean it from vertical to both sides, so that the cleaning liquid will flow along the inner wall of the tunnel;

[0051] When the dust removal liquid in the water tank 101 is insufficient, the impact force of the liquid sprayed by the first water spray gun 104, the second water spray gun 102 and the third water spray gun 402 will be reduced, thereby reducing the dust removal effect, so it is necessary to start the lifting mechanism 200 to lift and move the first cleaning mechanism 100 and the second cleaning mechanism 400;

[0052] When the first cleaning mechanism 100 and the second cleaning mechanism 400 need to be raised, the hoist 210 is started to retract the winding rope 208. During the retraction process, the winding rope 208 pulls the shaft 201 through the rope guide block 209. When the shaft 201 moves toward the hoist 210, it drives the slider 205 to move inside the fixing bar 207. When the slider 205 moves toward the fixing block 204, the support rod 202 lifts the mounting plate 206, thereby driving the first cleaning mechanism 100 and the second cleaning mechanism 400 to rise.

[0053] When the first cleaning mechanism 100 and the second cleaning mechanism 400 need to be lowered, the winch 210 is slowly released, and under the action of gravity, the first cleaning mechanism 100 and the second cleaning mechanism 400 will slowly descend by pressing the mounting plate 206 .

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
