Road and bridge construction surface spraying device and using method thereof

Abstract

The invention discloses a road and bridge construction surface spraying device and a using method thereof, and belongs to the technical field of equipment for road and bridge construction. The invention discloses the road and bridge construction surface spraying device and the using method thereof.The road and bridge construction surface spraying device comprises two fixing plates which are arranged in a front-back symmetrical structure, an infusion pump is arranged above the position between the two fixing plates, a first motor is arranged in a first motor box, a reciprocating lead screw is arranged at the front end of a main shaft, and a movable plate is arranged on the upper side of the right end face of a driving block. A protection assembly is arranged on the rear side of the rear end face of the movable plate, an atomization spray head is arranged on the bottom face of a liquid distribution box, and a feeding pipe is arranged at the output end of a liquid pump. Through cooperation of the first motor arranged in the first motor box, the reciprocating lead screw at the front end of the main shaft and the atomization spray head on the bottom face of the liquid distribution box, the liquid distribution box and the atomization spray head can reciprocate front and back to spray the surface of a bridge, a worker does not need to move the spraying device, and uniform spraying on the surface of the bridge is guaranteed, and damage to workers caused by the paint is reduced.

Description

technical field [0001] The invention relates to the technical field of road and bridge construction equipment, and more specifically, to a road and bridge construction surface spraying device and a method for using the same. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. Before the bridge is officially put into use, the staff need to spray the surface of the bridge. During this process, the staff often use the road and bridge construction surface spraying device. The prior art publication number is CN211865530U, which provides a surface spraying device for road and bridge construction. The device can facilitate the opening and closing of...

AI Technical Summary

Problems solved by technology

In order to make the surface of the bridge sprayed evenly enough, this method of construction is difficult and requires a high level of operator skills

In addition, these paints often have certain toxicity, and the staff are always close to the spraying device, and the paint will inevitably volatilize and splash during the spraying process, which will seriously damage the health of the staff; Spraying, set the filter cover with the target pattern and plug it on different nozzles, so as to spray the target pattern, and then use the liquid recovery mechanism to recycle the excess paint liquid, but this solution needs to carry the filter cover and It is blocked and equipped with a recycling system, so its high cost also makes the whole device heavy and inconvenient to transport
