Automatic paint spraying device for inner wall of tower drum

Abstract

An automatic paint spraying device for the inner wall of a tower drum comprises an axial walking device, a paint high-pressure filling device, a rotary driving device, a rotary spray head and a controller, and the controller is used for uniformly controlling starting and stopping of the axial walking device, the paint high-pressure filling device, the rotary driving device and the rotary spray head. A rotating plate is arranged on the upper surface of the axial walking device through a rotating mechanism, a supporting frame used for installing the rotary driving device is arranged on the rotating plate, the rotary driving device is connected with the rotary spray head through a transverse pipe, and the rotary spray head is located on the outer side of the axial walking device and the rotating plate. According to the device, under the regulation and control of the controller, according to manually-input necessary parameters, after primary moving spraying is completed, the rotary spraying head is turned, spraying on the positions which are not sprayed through primary axial movement is achieved through reverse axial movement, thorough spraying on all the positions of the inner wall of the tower drum is automatically achieved. The device has the advantages of being small and exquisite in overall structure, small in occupied space and capable of automatically achieving uniform spraying of the inner wall of the tower drum.

Description

technical field [0001] The invention relates to an automatic paint spraying device for the inner wall of a tower tube, and belongs to the technical field of large cylinder inner wall spraying equipment. Background technique [0002] Wind power towers are usually composed of tapered tubular steel towers with a diameter of 4-7 meters and a diameter of 20-30 meters. They have the characteristics of large diameter and long length. The painting of the tower surface is an important process in the process of manufacturing the tower. Most of the existing wind power tower inner wall painting is realized by manual high-pressure spraying, and the design of individual automatic spraying devices is not reasonable enough, and there are deficiencies. [0003] For example, the Chinese utility model patent "Name: A fully automatic paint spraying device for the inner wall of the wind power tower tube; announcement number: CN208230189U; announcement date: December 14, 2018" provides an automa...

AI Technical Summary

Problems solved by technology

This device can realize the spraying on the inner wall of the tower tube in a relatively closed environment, but the overall structure of the device is large and takes up a lot of space, and the range of movement of the nozzle on the screw is limited, so it is difficult to achieve uniform spraying on all parts of the inner wall of the tower tube. spraying
