Description

Technical Field

[0001] The invention relates to the technical field of road and bridge maintenance, in particular to a spraying device for road and bridge maintenance. Background Art

[0002] During the maintenance of roads and bridges, it is necessary to spray water on the roads and bridges to keep the roads moist and avoid dryness that causes the roadbed on the bridges to crack. During the maintenance spraying process, spraying equipment is needed for auxiliary operations. The spraying equipment generally includes a sprinkler system for spraying and a chassis vehicle mechanism for movement.

[0003] During use, the spraying nozzle generally has a fixed angle and cannot spray the designated area. Even if there are angle-adjustable nozzles on the market, the adjustment needs to be performed separately, and the angle cannot be adjusted during the spraying process. At the same time, the spraying range of the nozzle is fixed and cannot meet the needs of a large range of spraying operations. For some wider roads, continuous reciprocating spraying is required, which is very inconvenient. Therefore, in view of the above situation, it is urgent to develop a spraying equipment for road and bridge maintenance to overcome the shortcomings in current practical applications. Summary of the invention

[0004] The object of the present invention is to provide a spraying device for road and bridge maintenance to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A spraying device for road and bridge maintenance, comprising: a vehicle body; universal wheels, which are symmetrically arranged on the outside of the bottom end of the vehicle body and connected to the vehicle body, and are used to realize the movement of the vehicle body; a multi-directional synchronous spraying unit, which is arranged on the outside of the vehicle body and connected to the vehicle body, and is used to realize comprehensive spraying of the road surface; an automatic infusion unit, which is arranged on the inside of the vehicle body, connected to the vehicle body, and connected to the multi-directional synchronous spraying unit, and is used to realize the filtration of the liquid and complete the pressurization of the liquid delivery; wherein the multi-directional synchronous spraying unit comprises: an adjustable spraying component, an automatic retractable component and a bilateral A synchronous adjustment component, wherein the adjustable spray component is arranged on the outside of the vehicle body and is connected to the vehicle body. An automatic retractable component is arranged between the adjustable spray component and the vehicle body. The automatic retractable component is connected to the vehicle body and is used to cooperate with the vehicle body to realize the lifting and retracting of the adjustable spray component. A bilateral synchronous adjustment component is also arranged between the automatic retractable component and the adjustable spray component. The bilateral synchronous adjustment component is connected to the vehicle body and to the adjustable spray component, and is used to cooperate with the automatic retractable component in operation to drive the adjustable spray component to control the spray angles on both sides, thereby realizing the control of the spraying range and completing the comprehensive spraying of the road surface.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] When the device is running, water enters the inner side of the vehicle body along the automatic infusion unit, and the automatic infusion unit can filter and remove dust from the water entering the inner side of the vehicle body. When spraying, the automatic infusion unit drives the water located on the inner side of the vehicle body to flow, and can pressurize the transported water. The pressurized water enters the inner side of the adjustable spray assembly and is sprayed out from the adjustable spray assembly to complete the maintenance of the road surface. At the same time, the automatic retractable assembly can cooperate with the vehicle body to lift the adjustable spray assembly, thereby increasing the spraying range of the equipment, and according to the width of the road surface, the automatic retractable assembly is used to drive the bilateral synchronous adjustment assembly, and the bilateral synchronous adjustment assembly can drive the adjustable spray assembly to adjust the spray angles on both sides, thereby completing further adjustment of the spraying range. The spraying range of the nozzle is fixed, which cannot meet the needs of large-scale spraying operations. For some wider roads, continuous reciprocating spraying is required, which is very inconvenient. By setting a multi-directional synchronous spraying unit and cooperating with an automatic infusion unit, the spraying range can be accurately controlled, so that the equipment can perform full-coverage spraying on roads of different widths, greatly improving the spraying efficiency.

As the first piston enters the bilateral synchronous adjustment component 7, it can drive the bilateral synchronous adjustment component 7. The bilateral synchronous adjustment component 7 It can simultaneously drive the connecting tubes 14 on both sides to rotate, and then synchronously adjust the angles of the auxiliary nozzles 15 on both sides, complete the precise control of the spraying range, greatly improve the spraying efficiency, and can effectively reduce the waste of water resources. By setting the bilateral synchronous adjustment component 7, it can cooperate with the automatic retractable component 6 to complete the adjustment of the adjustable spray component 5, and then complete the adjustment of the spraying range, which improves the flexibility of the equipment when in use. By setting the automatic infusion unit 4, it can complete the transportation and pressurization of water mist, and can also automatically clean the filter frame 37, which improves the stability of the equipment during operation and can ensure the effectiveness of spraying. By setting the self-cleaning booster component 34, it can not only complete the pressurization of water mist, but also complete the automatic cleaning of the filter frame 37, which greatly improves the stability and reliability of the equipment during operation.
