Inner wall cleaning device of variable-diameter steel pipe

Abstract

The invention discloses an inner wall cleaning device of a variable-diameter steel pipe. The device comprises a baseplate, a left side plate, a right side plate and the variable-diameter steel pipe, wherein a clamping device is arranged at the right side of the left side plate and comprises a box, an upper arc-shaped clamping board and a lower arc-shaped clamping board; a sliding block and a baffle are arranged in the box and connected through a clamping spring; one end of the upper arc-shaped clamping board penetrates a guide hole in the box and is fixedly connected with the sliding block; a driving motor is arranged on the left side plate; an air cylinder is arranged on the right side plate; a pneumatic push rod is arranged at one side, which is close to the variable-diameter steel pipe, of the air cylinder; a fixing frame is fixedly connected at the left end of the pneumatic push rod; a cross bar is fixedly connected on the fixing frame; and a plurality of cleaning devices are arranged on the cross bar. The inner wall cleaning device disclosed by the invention is simple in structure, wide in application range and convenient in scrap discharging and has the advantages that inner walls of steel pipes with variable diameters and same diameter can be cleaned and the inner walls of the steel pipes are avoided being scratched at the same time.

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.
