Derusting equipment for reinforcing bars

Abstract

The invention discloses derusting equipment for reinforcing bars. The derusting equipment comprises a mounting plate, wherein a uniform velocity motor is mounted on the mounting plate; an output shaftof the uniform velocity motor is fixedly connected with a rotary disc; a clamping device is arranged on the rotary disc; a rotating rod is rotatably connected to the side wall of the mounting plate and is in transmission connection with the output shaft of the uniform velocity motor; a sector gear is mounted on the rotating rod; a main driving wheel is arranged on the output shaft of the uniformvelocity motor (2) in a sleeving manner; an auxiliary driving wheel is fixedly arranged on the rotating rod (4) in a sleeving manner; the height of the main driving wheel is identical to that of the auxiliary driving wheel; the main driving wheel is in transmission connection with the auxiliary driving wheel through a transmission belt; and a threaded rod is rotatably connected to the side wall ofthe mounting plate. The derusting equipment for the reinforcing bars disclosed by the invention has a good derusting effect on the side walls of building materials, and the whole side faces of the materials can be derusted, so that damage of the materials caused by over-large pressure of the materials also can be avoided.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a steel bar derusting equipment. Background technique [0002] According to my country's "Construction Quality Acceptance Code for Concrete Structure Engineering", the steel bars should be straight and undamaged, and the surface should not have cracks, oil stains, granular or flaky old rust. Corrosion of steel bars will bring potential safety hazards to buildings. Therefore, the derusting of steel bars can often be seen on construction sites. The methods of derusting steel bars generally include chemical derusting methods, machine derusting methods, sandblasting derusting methods and manual derusting methods. Rust method, among which the machine derusting method is more common. [0003] In the prior art, when derusting long strips of building materials such as pipes, rods, and steel bars, due to the long length, they are prone to bending after being stressed, which leads to...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, when derusting long strips of building materials such as pipes, rods, and steel bars, due to their long length, they are prone to bending after being stressed, resulting in the need to pull the rust after derusting. Straight, it greatly delays the construction period. In addition, rust removal needs to be carried out on multiple sides. The structure of turning over and rust removal is very complicated, and the effect is poor. A kind of steel rust removal equipment is proposed.
