Spraying robot capable of switching spraying amount and polishing inner wall

Abstract

The invention discloses a spraying robot capable of switching a spraying amount and polishing an inner wall. The spraying robot comprises a main body, wherein the front side, the rear side, the left side and the rear side of the main body are symmetrically provided with an upper group of wheel frame and a lower group of wheel frame; in each wheel frame, a wheel frame cavity which is vertically through is arranged, wherein the opening of the wheel frame cavity is far away from one side of the main body; an auxiliary wheel is independently rotatably connected between the front wall and the rearwall of the front walls and the rear walls of the two wheel frame cavities positioned on the left side and the right side as well as between the left walls and the right walls of the four wheel framecavities positioned on the front side and the rear side; a driving wheel is rotatably connected between the front wall and the rear wall of the wheel frame cavity on the upper side of the left side and the right side; and in the main body, a low double-side bevel gear cavity is arranged between the left wheel frame and the right wheel frame. By use of the spraying robot, an angle of a spraying hole, the flow of paint in a spraying pipeline and an amount of spraying holes are changed to regulate that paint can be evenly ejected under different speeds, meanwhile, when the device enters the pipeline, the inner wall of the pipeline can be firstly polished to increase pipeline inner wall roughness and a paint adhesion degree

Description

technical field [0001] The invention relates to the technical field of spraying equipment, in particular to a spraying robot that can switch the spraying amount and polish the inner wall. Background technique [0002] When we are spraying the inner wall of the pipeline, we will encounter inconvenient spraying because the pipeline is too long, or the spraying speed of the spraying device will be constant but the speed of the spraying device will be uneven, resulting in the uneven adhesion of the sprayed paint on the inner wall of the pipeline, which will affect the spraying effect. Quality, and sometimes the inner wall of the pipe is too smooth, which is not suitable for the adhesion of the paint. The paint will fall off during spraying, resulting in the incomplete spraying of the inner wall, and the thickness of the paint on the inner wall of the pipe is uneven. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the inve...

Problems solved by technology

[0003] Technical problem: when spraying the pipeline in the ordinary way, the pipeline is too long, which makes the spraying inconvenient, the speed is difficult to control, which leads to uneven coating during spraying, and the smooth inner wall of the pipeline makes the coating unable to adhere
