Building steel pipe inner wall and outer wall polishing and rust removing device

Abstract

The invention discloses a building steel pipe inner wall and outer wall polishing and rust removing device which comprises a bottom plate, wherein a transverse plate in parallel with the bottom plate is arranged above the bottom plate; a transverse shaft is arranged on a bracket; a semi-circular teeth gear is further arranged on the transverse shaft; an upper rack and a two-sided rack are arranged at the upper end and the lower end of the semi-circular teeth gear; a fixed sleeve rotatably connected with a support frame is arranged at one end of the support frame; a fixed mount is arranged at the end, far away from a rotary sleeve, of the lower end face of the transverse plate; an air cylinder is arranged at the left end of the fixed mount; a pneumatic push rod is arranged at the lower end of the air cylinder; an arc-shaped clamping plate is fixedly connected with the bottom end of the pneumatic push rod; an outer wall cleaning brush is arranged on the inner side of the arc-shaped clamping plate; and a cleaning guide pipe coaxial with the rotary sleeve is arranged on the lower side of the right side of the fixed mount. The building steel pipe inner wall and outer wall polishing and rust removing device is simple in structure, can simultaneously clean the inner wall and the outer wall of a steel pipe, is sufficient in cleaning, high in cleaning efficiency, higher in cleaning effect, stable in transmission and higher in practicality.

Description

technical field [0001] The invention relates to a construction machine, in particular to a device for grinding and derusting the inner and outer walls of a construction steel pipe. Background technique [0002] Some steel pipes will be used in the construction process. After the steel pipes are stored for a period of time, the outer surface will rust, which will affect the use of the steel pipes. The existing methods of derusting the steel pipes are mainly carried out by manual erasing. The efficiency is low, the labor intensity is high, the rust removal time is long, the rust removal effect is poor, and because the inner wall of the construction steel pipe is troublesome to clean, the inner wall of the general construction steel pipe is rarely cleaned, and the internal rust of the construction steel pipe will also affect the use of the steel pipe . Contents of the invention [0003] The object of the present invention is to provide a device for grinding and derusting the...
