A retractable detection arm device for bridge detection

Abstract

The invention provides a retractable detection arm device for bridge detection, which relates to the field of bridge detection and solves the problem that the automatic paint repair of the lack of paint on the bridge pipe body cannot be realized while the detection is in progress, and the paint repair cannot be realized. Automatic supply of paint sponge; since part of the pipe body on the bridge is a cylindrical pipe structure, the detection head is prone to deviation during detection. A retractable detection arm device for bridge detection, comprising a main body arm; a main body seat with a concave structure is rotatably connected to the main body arm, and an adjustment structure is also installed on the main body arm; the main body seat A limit structure is installed on the top, and two detection heads are symmetrically installed on the main body seat. Because there are spray holes in a rectangular array on the spray head, and the spray head has a V-shaped structure; the toggle arm is in contact with the telescopic paint bottle, and when the toggle arm moves backwards following the sponge seat, the telescopic paint bottle is in a state of squeezing and draining, Thereby the automatic feeding of the paint on the sponge is realized.

Description

technical field [0001] The invention belongs to the technical field of bridge detection, and more specifically relates to a retractable detection arm device for bridge detection. Background technique [0002] In the bridge maintenance work, it is necessary to carry out comprehensive inspection, repair and maintenance (painting, sandblasting, installation, dismantling, reinforcement) of the bridge pipes of the bridge, including crack detection at the bottom of the main girder of the bridge, inspection of bridge piers and full bridge supports maintenance. [0003] For example, the application number: CN201611041061.8, the present invention discloses a clamp arm structure for a bridge inspection vehicle, which includes a coaxial lower clamp arm swivel seat and an upper tong arm swivel seat, and the lower tong arm swivel seat drives The lower tong arm, the rotating seat of the upper tong arm drives the upper tong arm, the upper tong arm and the lower tong arm are both inclined ...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a retractable detection arm device for bridge detection, to solve the problem that the function of the existing device is not sound enough, for example: it is not possible to realize the detection of bridge pipes at the same time. It is not possible to automatically repair the paint on the lack of paint on the body, and cannot realize the automatic supply of paint repair sponges; moreover, the structure is poor. When the existing device detects the bridge pipe body, because part of the pipe body on the bridge is a cylinder Shaped pipe structure, which makes the detection head prone to deviation during detection, which affects the detection efficiency; finally, the bridge pipe body is divided into horizontal and vertical welding distributions, and the existing detection device cannot realize rapid angle adjustment of the detection head and Adjusted auto-lock issues
