Building supporting steel tube inner part rust cleaning brush head

Abstract

The invention discloses a rust-removing brush head inside a building support steel pipe, comprising: a rotating shaft, a fixed ring, a top ring, a moving ring, a connecting rod, a counterweight, a metal brush piece, a spring, and the output of the rotating shaft and a power motor The shaft is affixed, the fixed ring is affixed to the rear of the front end of the rotating shaft, the top ring is affixed to the top of the front end of the rotating shaft, the moving ring is slidably connected to the rotating shaft, and the moving ring is located between the fixed ring and the top ring. In between, the two ends of the counterweight are respectively connected to one end of the connecting rod through a pin shaft, wherein the other end of the front connecting rod is connected with the moving ring through a pin shaft, and the other end of the rear connecting rod is connected through a pin shaft It is connected with the fixed ring, the metal brush is fixed on the outside of the counterweight, the spring is sleeved on the rotating shaft, and the two ends of the spring are respectively connected with the fixed ring and the moving ring. The invention has the advantages of simple structure, meeting the technical requirements of internal rust removal, and good use effect.

Description

technical field [0001] The invention relates to the technical field of building auxiliary equipment, in particular to a brush head for removing rust inside a building support steel pipe. Background technique [0002] Many auxiliary devices are needed in the construction industry. For example, when excavating the foundation, it is necessary to use steel pipes to prop up the land on both sides to prevent it from raining or collapse due to its own weight. However, because the steel pipes are in the outdoor environment for a long time, they are easy to corrode. After use, it needs to be recycled, and recycling needs to be processed, such as rust removal and painting. However, for the internal rust removal, it is a difficult technical problem, because the contact pressure between the ordinary brush head and the steel pipe is not enough. Doesn't do a good job of removing rust. Contents of the invention [0003] The object of the present invention is to provide a brush head for ...
