Handheld steel bar rust removing machine

Abstract

The invention relates to a handheld steel bar rust removing machine which comprises a rust removing rack, a first connecting frame, a second connecting frame and sand rubbing cloth, a driving motor is installed in the rust removing rack, two handles are further installed on the rust removing rack, and the handles are oppositely arranged on the rust removing rack; one end of a cross rod in the first connecting frame is rotationally connected to the rust removing rack; the second connecting frame and the first connecting frame are oppositely arranged left and right, and one end of a cross rod in the second connecting frame is hinged to the rust removing rack; and the sand rubbing cloth is mounted between the first connecting frame and the second connecting frame, and the sand rubbing cloth can be driven by the driving motor to move left and right in a reciprocating manner. According to the steel bar rust removing machine provided by the invention, the sand rubbing cloth is driven by the driving motor in a left-right reciprocating manner, so that rust on a steel bar is quickly and flexibly removed.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a hand-held steel bar rust remover. Background technique [0002] Reinforced concrete structures are the most commonly used structures in various engineering constructions. Since most of the projects are open-air operations, sometimes the steel bars tied up due to time and / or weather reasons cannot be poured in time, which makes the steel bars often corrode. If the corroded steel bars are not treated, rust will form on the contact surface between the steel bars and the concrete, which will affect the structural strength. [0003] At present, although there are a lot of device structures about the corrosion of steel bars, these device structures are mostly only suitable for removing the rust on the surface of unused steel bars in bundles, and are not suitable for those processed or bound steel bars. Contents of the invention [0004] In view of the above problems,...

AI Technical Summary

Problems solved by technology

Due to the fact that most of the projects are carried out in the open air, the steel bars tied up due to time and / or weather reasons sometimes cannot be poured in time, which makes the steel bars often corrode

However, if the corroded steel bars are not treated, rust will form on the contact surface between the steel bars and the concrete, which will affect the structural strength.

[0003] At present, although there are many device structures for dealing with the corrosion of steel bars, most of these device structures are only suitable for removing the rust on the surface of unused steel bars in bundles, and are not suitable for those steel bars that have been processed or bound in place.
