Automatic sand blasting and spraying equipment

Abstract

The invention provides an automatic sand blasting and rust removing and spraying device, which comprises a moving support having a moving mechanism and supporting rails, a spraying car connected with a conveyor tube, a driving device and a control device, wherein the moving support comprises an arch-shaped truss and the moving mechanism arranged at the bottom. The supporting rails are arranged above the arch-shaped truss. The control device and the driving device are arranged on the moving support and drive the spraying car to move to and fro on the supporting rails. The spraying car consists of a chassis, a spraying car motor, a transmission mechanism, a crank-rocker mechanism and a spray gun fixing seat for mounting a sand-blasting gun or a painting nozzle, wherein the spraying car motor is fixed on the chassis and is connected with one end of the transmission mechanism. The other end of the transmission mechanism is connected with the crank-rocker mechanism. The spray gun fixing seat is fixed at the end of the crank-rocker mechanism. The device adopts a PLC to control the whole process, realizes the automation of the whole process, improves the working efficiency greatly, better ensures construction safety and project quality, and reduces unnecessary damages.

Description

technical field [0001] The invention relates to steel plate rust removal and painting technology, in particular to an automatic sand blasting rust removal and painting equipment suitable for arched steel plates. Background technique [0002] When various large-scale steel plates are used in construction, they usually need to be directly exposed to the air, which will easily cause the surface of the steel plate to be oxidized or stained with dust, moisture or other impurities, which will reduce the quality of the steel plate. Therefore, after the construction is completed, the steel plate usually needs to be removed The oxide layer or other impurities on the surface are then sprayed with paint to isolate it from the air, so as to achieve the purpose of protecting the steel plate. At present, the rust removal and paint spraying of steel plates in buildings are usually done manually. This method is simple and easy to implement, but its work efficiency is very low, and construct...

Problems solved by technology

At present, the rust removal and paint spraying of steel plates in buildings are usually done manually. This method is simple and easy to implement, but its work efficiency is very low, and construction safety is difficult to be guaranteed. Moreover, because the construction environment is an arched space, its work is also difficult. Large, while affecting work efficiency and construction safety, it also affects project quality
