High-pressure dust-catching spraying device capable of moving and lifting

The invention relates to a dustproof facility for tunnel dust catching, in particular to a high-pressure dust-catching spraying device capable of moving and lifting. The high-pressure dust-catching spraying device capable of moving and lifting mainly comprises an electromotor, a cylindrical cross shaft, a lifting device, a vertical telescopic device, a horizontal hollow water guide pipe, a spraying head, pulleys, a dust-catching net and the like. The electromotor can drive the cylindrical cross shaft through a belt to rotate, and a cross rod rotates to drive a rope to lift and bring down the horizontal hollow water guide pipe. Through ascending and descending of the horizontal hollow water guide pipe, a spraying area of the spraying head on the horizontal hollow water guide pipe covers thewhole dust-catching net. One end of the vertical telescopic device is fixed on a bracket and the other end of the vertical telescopic device is fixed on the horizontal hollow water guide pipe, so that the vertical telescopic device can only vertically move but cannot rotate. The front end of the spraying head is a convex surface, small holes are densely distributed in the convex surface and the convex surface enables the spraying area to be enlarged. The pulleys are arranged on bracket feet, so that the whole device can move to any position easily. The high-pressure dust-catching spraying device capable of moving and lifting is convenient to move, the covering range can be regulated and controlled, the dust of the working surface is reduced and the environment of the working surface is improved.
