Embodiment Construction

[0018] refer to Figure 1 to Figure 4 Examples of the present invention will be described.

[0019] The automatic rust removal and painting equipment for the inner wall of the pipeline mainly includes three parts: the rust removal device 1, the power device 2, and the paint spraying device 3. The rust removal device 1 and the power device 2 are connected and fixed by a universal coupling. The rotary front end 19 of the universal coupling is connected with the fixed panel 21 by bolts, the rotary rear end 23 of the universal coupling is connected with the worm 18 by bolts, and the rotary front end 19 of the universal coupling is connected with the rotary rear end 23 through the rotary middle end 20, which can Compensate the radial vibration, improve the smoothness of the inner wall of the pipeline after derusting, and provide convenience for the spraying of paint in the follow-up work;

[0020] The tension spring 28 of the derusting device 1 is installed in the draw-in groove o...

Abstract

The invention discloses an automatic rust-removal paint spraying device for an inner wall of a pipeline. The automatic rust-removal paint spraying device mainly comprises a rust removal device, a power device and a paint spraying device, wherein the rust removal device is fixedly connected with the power device through a universal coupler, the paint spraying device is movably connected with the power device through a hook and a hinge seat, a tension spring of the rust removal device is installed in a clamping groove of a fixed panel, a tension shaft is installed on the fixed panel through a slide bolt, a storage battery and a driving motor are sequentially installed on a soleplate of the power device, a worm is connected with the driving motor through a coupler, a worm gear is installed on a driving front shaft, and a rust absorption felt ring is arranged on the outer ring of a barrel of the paint spraying device in a sleeved manner. By integrating multiple functions, the automatic rust-removal paint spraying device can be used for performing rust removal, clearing and paint spraying on the inner wall of the pipeline simultaneously, can achieve an integrated operation effect, and has the advantages of being concentrated in size and efficient and convenient to operate; the rust removal device is provided with a self-tension mechanism, so that the automatic rust-removal paint spraying device is applicable to different pipelines of different sizes, and the application range of the device is greatly enlarged.

Description

technical field [0001] The invention relates to a rust-removing and painting equipment for the inner wall of a pipeline, in particular to an automatic rust-removing and painting equipment for the inner wall of a long-distance small-diameter pipeline. Background technique [0002] At present, for the rust removal and painting of the inner wall of long-distance small-diameter pipes on the market, PIG physical cleaning technology is mainly used. This equipment has a relatively single specification and size, not only has a small scope of application, but also has complex equipment. At the same time, due to the short pigging distance, multiple repeated treatments are required, which is time-consuming and laborious, and the painting operation cannot be completed at the same time, so the work efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide an automatic derusting and painting equipment for the inner wall of the pipeline. The...
