Building steel bar rust removal and prevention device

Abstract

The invention relates to the field of buildings, in particular to a building steel bar rust removal and prevention device. The device comprises a motor, wherein an output shaft is installed at one endof the motor, four first gears are installed on the outer side of the output shaft, and the first gears are in engagement with a spiral pushing device which comprises a second gear ring in engagementwith the first gears. Four first rod bodies are uniformly distributed on the inner side of the second gear ring, a first bearing pedestal is arranged at the other end of each first rod body, a secondrod body is installed in the middle of each first bearing pedestal, and a conveyer roller is installed at one end of each second rod body. Through arrangement of the first gears, the second gear ring, the first rod bodies, the first bearing pedestals, the conveyer rollers, a bevel gear, a bevel gear ring, a rust removal device and a rust-proof spraying device, when the device is used for removingrust on steel bars, the steel bars only need to be inserted into the space between the conveyer rollers from the left side without frequent mounting, fixing and dismounting, and the rust removal efficiency of the device is improved; and meanwhile, after rust on the steel bars are completely removed, and rust-proof liquid is sprayed on the steel bars immediately to prevent the steel bars from rusting again.

[0002] Steel bar refers to the steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is circular, sometimes square with rounded corners, including smooth round steel bars, Ribbed steel bars and twisted steel bars, steel bars for reinforced concrete refer to straight or coiled steel materials for reinforced concrete reinforcement, and their shapes are divided into two types: smooth round steel bars and deformed steel bars, and the delivery status is straight and coiled. The light round steel bar is actually a small round steel bar and a round steel bar of ordinary low carbon steel. The deformed steel bar is a steel bar with ribs on the surface, usually with 2 longitudinal ribs and transverse ribs evenly distributed along the length direction. The shape of the transverse ribs is There are three types of spiral, herringbone, and crescent-shaped. The steel bar mainly bears the tensile stress in the concrete. The deformed steel bar has a greater bonding capacity with the concrete due to the effect of ribs, so it can better withstand the action of external forces. The steel bar is widely used. For various building structures, especially large, heavy, light thin-walled and high-rise building structures, building steel bars refer to various steel bars and steel wires used in reinforced concrete. The existing steel bars have different lengths, sizes and shapes. Long-term open-air storage is easy to get wet, resulting in rust and dust on the surface of steel bars that are difficult to remove. Most steel bars are manually derusted, which requires a lot of labor and time, and the effect of manual derusting is poor. Therefore, it is urgent to research and develop A kind of derusting device for building steel bars that can be applied to various steel bars and has better derusting effect

[0003] After retrieval, Chinese Patent No. is CN107520729B patent, discloses a kind of steel bar derusting device for construction, the technical problem to be solved in the present invention is to provide a kind of construction With steel bar derusting device, in order to solve above-mentioned technical problem, improvement invention provides such a kind of construction steel bar derusting device, comprises top plate, slide block, first connecting rod, moving device, hair brush, L-shaped bar, clamping block etc.; the middle part of the bottom of the top plate is provided with a slide rail, and the left and right sides of the slide rail are symmetrically provided with sliders. The bottom is connected with a brush, and the left and right sides of the bottom of the top plate are symmetrically connected with L-shaped rods. The L-shaped rods are located on the left and right sides of the slide rail. It meets the needs of steel bar rust removal for construction. The steel bar rust removal is more thorough, the steel bar rust removal range is large, and at the same time it is easy to disassemble and replace the brush effect. Building steel bars are generally used in batches, and the derusting efficiency of this device is low. At the same time, if the steel bars are not put into use immediately after derusting, they will easily rust again in a humid environment.
