An in-pipe spraying device suitable for bent pipes

Abstract

The present invention relates to the related field of building material processing, more specifically, it is an in-pipe spraying device suitable for curved pipes, including a distance adjustment mechanism, an angle adjustment mechanism, a height adjustment mechanism, a propulsion mechanism, an elbow mechanism and a material box. The angle adjustment mechanism is threadedly connected with the distance adjustment mechanism, the distance adjustment mechanism is fixedly equipped with a material box, the height adjustment mechanism is rotatably installed on the angle adjustment mechanism, the propulsion mechanism is fixedly installed on the height adjustment mechanism, and the elbow mechanism is fixedly installed on the propulsion mechanism. The elbow mechanism is fixedly connected with the material box; the device sprays in a rotating manner to avoid uneven spraying caused by blockage of individual nozzles. The device not only has the function of spraying straight pipes, but also has the function of spraying the bends of pipe fittings .

Description

An in-pipe spraying device suitable for curved pipes technical field [0001] The present invention relates to the related field of building materials processing, and more particularly to a pipe in-pipe spraying device suitable for curved pipes. Background technique In order to improve the anti-rust ability of pipe fittings, the inner and outer walls of pipe fittings need to be sprayed and treated, and common spraying methods are used. The method is to use manual spraying, which is too labor-intensive and requires a lot of labor, especially the manual work on the inner wall of the pipe fittings. The spraying effect is poor, the spraying distance is limited, and at the same time, it is impossible to spray the bend of the pipe. SUMMARY OF THE INVENTION The technical problem that the present invention mainly solves is to provide a kind of in-pipe spraying device that is applicable to bent pipe, and this device passes through Spraying is carried out in a rotating way to ...
