Automatic brushing device for waterproof coating on inner wall of tunnel

Abstract

The invention relates to an automatic brushing device for a waterproof coating on the inner wall of a tunnel, and belongs to the technical field of tunnel waterproof construction. The automatic brushing device comprises a slide rail, a base movably assembled on the slide rail, a support frame, a waterproof coating brushing assembly and a material baffle plate, the base is provided with a waterproof coating stirring barrel and a material spraying barrel, and the support frame is provided with a gear transmission assembly and a gear driving motor; the waterproof coating brushing assembly comprises a hydraulic telescopic rod, a supporting plate connected to the driving end of the hydraulic telescopic rod, a coating brush installed on the supporting plate and a coating sprayer; the material baffle plate is arc-shaped and is provided with a containing groove, and power of the gear driving motor is transmitted to the hydraulic telescopic rod through the gear transmission assembly to drive the coating brush to brush the waterproof coating along the inner wall of the tunnel; and the splashed waterproof coating is blocked by the material baffle plate to enter the containing groove and flows into the material spraying barrel, so that waste is avoided. According to the automatic brushing device for the waterproof coating on the inner wall of the tunnel, automatic spraying and automatic brushing of the waterproof coating can be achieved, and the construction efficiency and the construction safety are improved.

Description

technical field [0001] The invention relates to the technical field of tunnel waterproof construction, in particular to an automatic brushing device for waterproof paint on the inner wall of a tunnel. Background technique [0002] A tunnel is a building built underground or underwater or in a mountain, laying a railway or building a road for the passage of motor vehicles. According to its location, it can be divided into three categories: mountain tunnels, underwater tunnels and urban tunnels. In order to shorten the distance and avoid large ramps, it is called a mountain tunnel that passes under mountains or hills; in order to cross rivers or straits, it is called an underwater tunnel that passes under a river or under the sea; in order to meet the needs of railways passing through large cities, it is called a tunnel. Those that pass underground are called urban tunnels. [0003] During the construction of the tunnel, it is necessary to spray waterproof coating on the tun...
