Frame beam bottom paint spraying device

Abstract

The invention relates to a frame beam bottom paint spraying device. The frame beam bottom paint spraying device comprises a base and a supporting stand column. The supporting stand column is composed of a fixing rod, a telescopic rod and a fixing bolt. Through holes are formed in the fixing rod and the telescopic rod at equal intervals. The fixing rod and the base are fixedly connected into a whole body. The telescopic rod is installed in the fixing rod and moves up and down along the fixing rod. Two supporting arm rods are symmetrically arranged on the upper portion of the telescopic rod left and right. Each supporting arm rod is of a telescopic structure. The top ends of the two supporting arm rods are fixedly connected with symmetrical protective covers. The ends, close to each other, of the two protective covers are provided with reverse edge plates attached to the side face of a bottom beam. According to the frame beam bottom paint spraying device, the situation that paint is sprayed to the beam side, a frame top plate and other positions where the paint surface is not damaged can be effectively avoided; the situation that after the paint is sprayed into air and falls down, vehicles in a garage and the ground are polluted is avoided; and environment protection before spraying is not needed, the spraying range is effectively controlled, and the paint is saved.

Description

technical field [0001] The invention belongs to a device for anti-corrosion spraying of frame beams, in particular to a device for spraying the bottom of frame beams. Background technique [0002] After the garage is put into use, due to the long-term damp and cold environment, the bottom of the beam will appear back stitching, and the service life of the building will be affected if the steel bars are seriously corroded. The maintenance method in the prior art is: earlier the surface coating on the bottom surface of the steel girder beam is shaved off, the original beam surface maintenance is carried out, and the coating at the bottom of the beam will be recovered after the maintenance. To restore the paint surface, use spraying equipment to spray paint to the bottom of the beam. The nozzle of the spraying equipment has a wide angle. Part of the paint sprayed outside the beam will pollute the vehicles parked in the garage. Therefore, it is necessary to cover the vehicles an...

Problems solved by technology

The defect of touch-up paint spraying in the prior art is: since the side of the beam and the roof do not need maintenance, it is easy to spray paint on the side of the beam and the bottom of the board again during spraying, which not only wastes paint, but also affects the appearance of the garage surface after the old and new paint intersect.
