Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and particularly relates to a dust suppression vehicle for bridge construction. Background Art

[0002] During the process of bridge construction, operations such as drilling, blasting, and excavation will generate a large amount of dust. The dust floats in the air, which not only reduces visibility, increases the construction difficulty, but also causes great harm to the physical health of construction workers. Therefore, dust suppression is required during construction.

[0003] There is a prior art solution of using a dust suppression vehicle to suppress dust. When suppressing dust, the dust suppression vehicle travels in the area where the dust floats and sprays water mist into the surrounding environment. After the dust comes into contact with the water mist, the water mist particles will adsorb more dust and increase in weight, causing the dust to fall to the ground to achieve dust suppression. However, when suppressing dust in this way, the dust suppression range is limited, and the sprayed water mist range is small. The width of the bridge is much larger than the width of the dust suppression vehicle, so that the water mist cannot completely cover the area where the dust is located, and it is necessary to make multiple round trips for dust suppression, which not only has a low dust suppression efficiency but also affects the construction efficiency of the construction workers. Summary of the Invention

[0004] The purpose of the present invention is to provide a dust suppression vehicle for bridge construction, which solves the problems of low dust suppression efficiency and low construction efficiency of construction workers due to the small water mist coverage range during dust suppression in the prior art.

And the water pump system is used to pump water flow into the extendable dust suppression device. The flip device is used to adjust the angle of the extendable dust suppression device. A support device and a backwash device are arranged on each extendable dust suppression device;

[0007] Wherein, the extendable dust suppression device unfolds or retracts along the direction perpendicular to the movement of the vehicle body and sprays water mist. The support device is used to support the unfolded extendable dust suppression device.

Detailed implementation

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figures 1 to 6 shown, the present invention provides a dust suppression vehicle for bridge construction, including a vehicle body 1. A water tank 2 and a water pump system communicating with the water tank 2 are arranged on the vehicle body 1. Flip devices 3 are arranged on both sides of the water tank 2. Each flip device 3 is provided with a telescopic dust suppression device 4 rotatably connected to the outer wall of the water tank 2. And the water pump system is used to pump water flow into the telescopic dust suppression device 4. The flip device 3 is used to adjust the angle of the telescopic dust suppression device 4. Each telescopic dust suppression device 4 is provided with a support device 5 and a backwash device 6.

[0029] Among them, the telescopic dust suppression device 4 unfolds or retracts along the direction perpendicular to the movement of the vehicle body 1 and sprays water mist. The support device 5 is used to support the unfolded telescopic dust suppression device 4. The backwash device 6 can rotate around the telescopic dust suppression device 4 and gather the sprayed water mist when rotating above the telescopic dust suppression device 4 to flow back to the surface of the telescopic dust suppression device 4.

[0030] In the actual application of the present invention, the telescopic dust suppression device 4 is in contact with the outer wall of the water tank 2, so that the total width of the vehicle body 1 plus the two telescopic dust suppression devices 4 on both sides remains the width of a normal vehicle, avoiding affecting other vehicles when driving on the road.

[0031] When dust suppression is required, the vehicle body 1 drives the water tank 2 to the area where dust suppression is needed. Subsequently, the flipping device 3 controls the telescopic dust suppression device 4 to rotate to the horizontal state. The telescopic dust suppression device 4 unfolds according to actual needs, and the unfolded telescopic dust suppression device 4 is supported by the support device 5 to ensure the stability of the telescopic dust suppression device 4 during the dust suppression process. The water pump system pumps the water in the water tank 2 to the telescopic dust suppression device 4 to spray water mist. Since the telescopic dust suppression device 4 unfolds when in the horizontal state and the unfolding direction is perpendicular to the moving direction of the vehicle body 1, the width of the water mist sprayed by the telescopic dust suppression device 4 is much larger than that of the prior art, increasing the dust suppression area when the vehicle body 1 travels once, thereby reducing the number of round trips required for the vehicle body 1, improving the dust suppression efficiency, and reducing the interference with the operation construction, thus improving the construction efficiency of the operators.

[0032] The setting of the backflush device 6 is used to clean the surface of the telescopic dust suppression device 4. When the backflush device 6 rotates above the telescopic dust suppression device 4, it will hinder the spraying of the water mist, causing the water mist to accumulate on the backflush device 6 and drip downward in a water flow state, thereby cleaning the surface of the telescopic dust suppression device 4 and ensuring the cleanliness of the surface of the telescopic dust suppression device 4.

[0033] The flipping device 3 includes a winding roller 301 rotatably arranged on the outer wall of the water tank 2 and a first spring 302 horizontally and fixedly arranged on the outer wall of the water tank 2. A traction rope 303 connected to the telescopic dust suppression device 4 is wound around the winding roller 301. The end of the first spring 302 is fixedly connected with a connecting seat 304. A sliding seat 305 slidably connected to the telescopic dust suppression device 4 is movably connected to the connecting seat 304, and the first spring 302 deforms in the horizontal direction.

[0034] When the flipping device 3 is in use, the winding roller 301 is driven to rotate by a driving device such as a motor, etc., so as to wind or release the traction rope 303. When the winding roller 301 releases the traction rope 303, the telescopic dust suppression device 4 rotates outward from the water tank 2 under the action of gravity and the elastic force of the first spring 302 until it reaches the horizontal state. Through the traction force of the traction rope 303, the self-gravity of the telescopic dust suppression device 4 and the elastic force of the first spring 302, the angle adjustment of the telescopic dust suppression device 4 is realized. When the winding roller 301 winds the traction rope 303, the traction rope 303 pulls the telescopic dust suppression device 4 to rotate towards the water tank 2, preventing the overall width of the vehicle body 1 from being too large and affecting the vehicles driving normally on the road.

[0035] When the first spring 302 exerts an elastic force on the telescopic dust suppression device 4, the connecting seat 304 rotates around the sliding seat 305, and the sliding seat 305 slides along the surface of the telescopic dust suppression device 4 to ensure the normal telescopic deformation of the first spring 302.

[0036] A cylindrical cylinder 306 is provided on the outer wall of the water tank 2. A sliding sleeve 307 is slidably sleeved inside the cylindrical cylinder 306. The first spring 302 is arranged inside the cylindrical cylinder 306 and connected to the inner bottom of the cylindrical cylinder 306. The sliding sleeve 307 is sleeved outside the first spring 302 and connected to the end of the first spring 302 away from the cylindrical cylinder 306.

[0037] In order to prevent the first spring 302 from being bent during deformation, the sliding sleeve 307 and the cylindrical cylinder 306 jointly limit the bending of the first spring 302. The cylindrical cylinder 306 limits the movement path of the sliding sleeve 307, so that the sliding sleeve 307 slides inside the cylindrical cylinder 306 along the length direction of the first spring 302, and the sliding sleeve 307 is connected to one end of the first spring 302 to move with the first spring 302, avoiding interference with the deformation of the first spring 302 and preventing the first spring 302 from being bent.

[0038] The telescopic dust suppression device 4 includes a main pipe 401 rotatably connected to the outer wall of the water tank 2 and connected to the water pump system. The axis of the main pipe 401 is parallel to the moving direction of the vehicle body 1. A plurality of telescopic pipes 402 are communicated with the main pipe 401 at equal intervals along the length direction. A plurality of nozzles 403 are embedded in each telescopic pipe 402, and the spraying directions of the plurality of nozzles 403 are respectively vertically upward or vertically downward. The ends of the plurality of telescopic pipes 402 are commonly connected to a cross bar 404. A telescopic assembly 405 connected to the cross bar 404 is arranged on the outer wall of the main pipe 401. The telescopic pipes 402 are pulled to contract or expand through the telescopic assembly 405. The supporting device 5 and the recoil device 6 are both arranged on the cross bar 404. The towing rope 303 is connected to the cross bar 404. The sliding seat 305 is slidably connected to the outer wall of the telescopic pipe 402.

[0039] The telescopic dust suppression device 4 drives the cross bar 404 through the telescopic assembly 405 to drive the plurality of telescopic pipes 402 to expand at the same time, and conveys the water pumped by the water pump system to the plurality of telescopic pipes 402 respectively through the main pipe 401, and sprays the water to the outside through the nozzles 403 on the telescopic pipes 402 to form water mist for dust suppression. The spraying range of the nozzles 403 is adjusted by the telescopic movement of the telescopic pipes 402, so that the width of the water mist sprayed by the telescopic pipes 402 is much larger than that of the prior art, increasing the dust suppression area during the driving of the vehicle body 1, reducing the round-trip times during dust suppression, improving the dust suppression efficiency, reducing the interference with the construction, and improving the operation efficiency.

[0040] In this embodiment, the telescopic pipes 402 are a plurality of straight pipes slidably sleeved in sequence, and the telescopic assembly 405 is an existing technology such as an electric push rod that can perform telescopic movement.

[0041] The nozzles 403 are embedded in the telescopic pipes 402 to prevent the nozzles 403 from interfering with the movement of the telescopic pipes 402 when the telescopic pipes 402 are telescoping.

[0042] The supporting device 5 includes a base 501 rotatably arranged on the cross bar 404, and the base 501 is connected to a driving device via a rotating shaft. A lifting device 502 is arranged on the side of the base 501 away from the cross bar 404, and a supporting seat 503 is arranged at the end of the lifting device 502, and a roller 504 is arranged on the supporting seat 503.

[0043] The support device 5 drives the shaft to rotate through a driving device such as a motor, and the base 501 rotates synchronously through the drive of the shaft, thereby adjusting the angle of the lifting device 502, so that when the telescopic dust suppression device 4 rotates to a horizontal state, the lifting device 502 is perpendicular to the ground, and the roller 504 is in contact with the ground, so that the support device 5 as a whole can move with the vehicle body 1 and support the telescopic dust suppression device 4, thereby ensuring the stability of the telescopic dust suppression device 4 when it is in motion.

[0044] A sleeve 505 is disposed at the bottom of the support seat 503 , a sliding seat 507 is slidably connected to the sleeve 505 via a second spring 506 , and the roller 504 is disposed on the sliding seat 507 .

[0045] Taking into account the changes in road conditions, there may be small obstacles such as stones on the road. When the roller 504 comes into contact with these small obstacles, it drives the slide 507 to slide in the sleeve 505 and compresses the second spring 506 to produce a buffering effect. Since the roller 504 is blocked by the small obstacle, it will roll onto the small obstacle and lift the cross bar 404, so that the telescopic dust reduction device 4 compresses the first spring 302. After the roller 504 passes the small obstacle, the telescopic dust reduction device 4 vibrates up and down under the elastic force of the first spring 302, and the buffering of the second spring 506 prevents the up and down vibration of the telescopic dust reduction device 4 from damaging the supporting device 5.

[0046] The recoil device 6 includes two supports 601 respectively fixed on the cross bar 404 and the main pipe 401, and the two supports 601 are rotatably connected with a telescopic plate 602. The telescopic plate 602 includes a plurality of arc plates 603 slidably connected in sequence, and the inner arc surface of each arc plate 603 faces the telescopic pipe 402. The two outermost arc plates 603 are rotatably connected to the two supports 601 through the rotating plate 604 respectively. The two supports 601 are slidably inserted with a limit pin 605, and the limit pin 605 is used to be inserted into the rotating plate 604 when the telescopic plate 602 rotates to the top of the telescopic pipe 402.

[0047] When in use, the recoil device 6 drives the entire telescopic plate 602 to rotate by rotating the rotating plate 604, so that the telescopic plate 602 rotates to directly above the telescopic pipe 402. When the nozzle 403 sprays water mist, the water mist will gather on the inner arc surface of the arc-shaped plate 603 and drip downward along the inner arc surface of the arc-shaped plate 603, thereby washing the dust on the surface of the lower telescopic pipe 402 and keeping the surface of the telescopic pipe 402 clean.

[0048] The limit pin 605 is used to insert into the rotating plate 604 when the telescopic plate 602 gathers water mist, so that the telescopic plate 602 is fixed in position to gather water mist to wash the telescopic pipe 402.

[0049] A plurality of grooves 606 are provided on the inner arc surface of the arc-shaped plate 603.

[0050] By providing a plurality of grooves 606 to gather water mist to form a water flow, the gathered water flow can drip downward along the notch of the groove 606, increasing the number of positions where the water can drip, enlarging the washing area, and improving the cleaning effect.

[0051] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
