Cleaning device of reserved steel bar

Abstract

The invention discloses a cleaning device of a reserved steel bar. The device comprises a mobile base, a vertical lifting rod, a rotation motor, a rotation shaft, connection rods, sliding blocks, first springs and arc brushing boards; the rotation shaft is horizontally arranged, and two or more connection rods are evenly arranged at the other end of the rotation shaft in the circumferential direction; a sliding block is connected to each connection rod in a sliding mode, and an arc brushing board is fixedly arranged on each sliding block respectively; all arc brushing boards comprise arc electromagnets, water filling bags, second springs, arc supporting plates and brush hair; the water filling bags are fixedly glued to the inner sides of the arc electromagnets, and the arc supporting plates are arranged on the inner sides of the water filling bags and fixedly connected with the arc electromagnets through the second springs; a plurality of water spraying holes are formed in the sides, towards the arc supporting plates, of the water filling bags, and a plurality of through holes corresponding to the water spraying holes are formed in the arc supporting plates; the brush hair is evenly arranged on the inner side walls of the arc supporting plates. According to the cleaning device of the reserved steel bar, sliding and adjustment can be conducted according to the position and height of the reserved steel bar, the labor intensity is low, and the cleaning efficiency is high.

Description

technical field [0001] The invention relates to the field of reinforced concrete construction, in particular to a reserved steel bar cleaning device. Background technique [0002] For a long time, the bonding force of reinforced concrete members has been valued by the engineering community. The factors affecting the bonding force are mainly composed of three parts: chemical bonding force, frictional resistance, and mechanical bite force. In order to ensure the bond strength of reinforced concrete members, it is necessary to use reserved reinforcement, which usually includes column inserts and shear wall inserts. [0003] However, during the construction process of pouring concrete, especially during the process of vibrating and pouring, the concrete cement slurry is often splashed onto the surface of the reserved steel bar, especially the jointing position of the reserved steel bar. It is very difficult to treat the cement slurry splashed on the reserved steel bars. If it i...

Problems solved by technology

[0007] 1. When in use, it is always necessary to manually lift and twist the handle. The watering can filled with water and the motor are heavy, and it takes a long time to lift and twist, which increases the labor intensity of the workers and the cleaning efficiency is also low.

[0008] 2. Only a small part of the water sprayed by the nozzle will drip on the brush head, and most of it will drip on the lower part of the newly poured concrete, which is prone to sand flooding
