Painting device for building steel pipe

Abstract

The invention discloses a painting device for a building steel pipe. The painting device for the building steel pipe comprises a base, wherein a left rotary lead screw is rotatably connected to the inner wall of one side of the base through a rotary shaft, a right rotary lead screw is welded to one end of the left rotary lead screw, a first movable seat is screwed and connected to the outer wall of the left rotary lead screw through threads, a second movable seat is screwed and connected to the outer wall of the right rotary lead screw through threads, and a first motor is fixedly connected tothe top of the first movable seat through a bolt. According to the painting device for the building steel pipe, through the movement of screw sleeves, a first connecting rod and a second connecting rod which are arranged in a crossed mode eject a clamping plate to the outer side and are supported at the inner side wall of the steel pipe to fix the steel pipe, on one hand, clamping and fixing of the steel pipe are guaranteed, the position stability of the steel pipe during subsequent painting is guaranteed, on the other hand, contact with the outer wall of the steel pipe is avoided, it is guaranteed that the outer wall of the steel pipe makes fully contact with oil paint, and omnibearing painting is guaranteed.

Description

technical field [0001] The invention relates to the technical field of steel pipes, in particular to a painting device for construction steel pipes. Background technique [0002] The steel pipe has a hollow section, the length of which is much longer than the diameter or circumference of steel, and is divided into round, square, rectangular and special-shaped steel pipes according to the cross-sectional shape. [0003] However, most of the existing construction steel pipes need to be painted on the surface of the steel pipes in order to avoid rusting of the steel pipes and prolong the service life of the steel pipes. Most of the existing steel pipes are painted manually, which is not only time-consuming and laborious, but also causes Uneven painting causes uneven paint coating thickness and increases the corrosion rate of steel pipes. There is a lack of a device that can adapt to different steel pipe painting and paint the steel pipe surface fully and evenly. Contents of t...
