Handheld diameter-variable reinforcing steel bar electric derusting device and using method thereof

Abstract

The invention relates to a handheld diameter-variable reinforcing steel bar electric derusting device and a using method thereof. The device comprises a machine body, a cylinder body, a steel wire brushing plate, an elastic fixing piece, a gear-carried motor and a derusting agent liquid-injection box. The machine body is of a rotating retractable structure; the cylinder body is composed of two oppositely combined half cylinder bodies; the steel wire brushing plate made of steel wires is of a circular arc structure, and the steel wire brushing plate is fixed in the cylinder body through the elastic fixing piece; a gear ring is arranged on the outer side of the cylinder body and engaged with a gear of the gear-carried motor mounted in the machine body in a transmission mode so as to enable the cylinder body and the machine body to rotate relatively and drive the steel wire brushing plate to rotate around a reinforcing steel bar to conduct derusting; a handle is arranged on the outer side of the machine body; an electric motor start button is arranged on the handle; and the derusting agent liquid-injection box is fixed on the top of the machine body. According to the handheld diameter-variable reinforcing steel bar electric derusting device and the using method thereof, rapid derusting is conducted on the reinforcing steel bar by adopting an electric derusting mode, the structure is simple and light, handheld operation is convenient, labor intensity of a worker is reduced greatly, derusting efficiency is improved, and the derusting effect is strengthened.

Description

technical field [0001] The invention relates to the technical field of steel bar derusting, in particular to a hand-held variable-diameter steel bar electric derusting device and a use method thereof. Background technique [0002] At present, during the construction of reinforced concrete, due to some reasons, the installed or uninstalled steel bars are often exposed to the air for a period of time, and the steel bars interact with the moisture in the air, and corrosion will soon occur, such as delamination (segmentation) ) Corrosion of steel bars at layers (sections) after concrete construction; corrosion of steel bars will reduce the bonding force between steel bars and concrete during concrete construction, resulting in a decrease in the bearing capacity of reinforced concrete and directly affecting its use.

[0002] At present, during the construction of reinforced concrete, due to some reasons, the installed or uninstalled steel bars are often exposed to the air for a period of time, and the steel bars interact with the moisture in the air, and corrosion will soon occur, such as delamination (segmentation) ) Corrosion of steel bars at layers (sections) caused by concrete construction; corrosion of steel bars will reduce the bonding force between steel bars and concrete during concrete construction, resulting in a decrease in the bearing capacity of reinforced concrete, directly affecting its use function

[0003] In the past, the rust removal of steel bars was manually brushed with a wire brush to remove the rust on the surface of the steel bars. The labor intensity was high, and the rust removal speed was slow, which wasted manpower and material resources, affected the construction efficiency, and seriously affected the progress of the project construction.
