Inner wall cleaning device of variable-diameter steel pipe

Abstract

The invention discloses a device for cleaning the inner wall of a variable-diameter steel pipe, which includes a base plate, a left side plate, a right side plate and a variable-diameter steel pipe. The arc-shaped clamping plate and the lower arc-shaped clamping plate are provided with a sliding block and a baffle in the box, the sliding block and the baffle are connected by a clamping spring, and one end of the upper arc-shaped clamping plate passes through the guide hole on the box body Fixedly connected with the sliding block, the left side plate is provided with a drive motor, the right side plate is provided with a cylinder, the side of the cylinder close to the variable diameter steel pipe is provided with a pneumatic push rod, and the left end of the pneumatic push rod is fixedly connected with a fixing frame. A crossbar is fixedly connected to the fixed frame, and a plurality of cleaning devices are arranged on the crossbar. The invention has a simple structure, can clean the inner walls of steel pipes with varying diameters and steel pipes with the same diameter, has a wide range of application, is convenient to discharge waste chips, and simultaneously avoids scratches on the inner walls of the steel pipes.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a cleaning device for the inner wall of a variable-diameter steel pipe. Background technique [0002] The steel pipe is used to transfer fluid and powder, exchange heat and produce mechanical parts and containers, what's more it's a kind of economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight, save metal by 20-40%, and realize factory-like mechanized construction. (Tianjin Steel Pipe Co., Ltd.’s processing workshop actually saves 42.9% of steel because of the steel pipe grid structure). Using steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of ​​​​the protective layer, saving investment and maintenance costs. . Therefore, there's no other type of steel product that can completely replace the steel pipe, but the steel pipe can replace part of...

AI Technical Summary

Problems solved by technology

In some fields, when steel pipes need to be applied, the inner wall needs to be cleaned, such as water diversion pipes, and general cleaning devices can only clean steel pipes with the same diameter, and the cleaning of variable diameter steel pipes is more troublesome.
