Dry powder accelerator filling and shotcrete support

Abstract

The invention provides a filling and guniting support frame for dry powder accelerating agent. The filling and guniting support frame comprises a base, a lifting strut, travelling wheels, a dust raising box, springs and a pipe clamp. The filling and guniting support frame combines the supporting and the filling of the accelerating agent into a whole and has a simple integral structure, but the mixing evenness of the accelerating agent is much higher than the mixing evenness of the existing equipment. A spiral dust raising pipeline is arranged in the dust raising box, the pipe wall of the dust raising pipeline is provided with small through holes which are evenly distributed, one end of the dust raising pipeline is connected to an air inlet pipeline, and the other end of the dust raising pipeline is sealed. According to the filling and guniting support frame for the dry powder accelerating agent, the spray gun of a guniting machine can be fixed, the spraying of concrete is realized, the height and the angle of a sprayer can be regulated in a spraying process, the equipment can flexibly and conveniently move in a working process by a three-foot type base, and the flexibility of the equipment is increased.

Description

technical field [0001] The invention belongs to auxiliary equipment for construction and mining spraying machines, in particular to a dry powder quick-setting agent filling and spraying support frame for adding quick-setting agents. Background technique [0002] Shotcrete machine is a kind of equipment that has been used more and more widely in recent years. It is mostly used in construction, mining and other fields. It uses compressed air to spray concrete onto the surface of the wall and make it solidify quickly so as to achieve the effect of concrete covering the wall. As a result, in order to make the concrete sprayed on the wall solidify quickly, a certain amount of quick-setting agent is often added during the spraying process, which can make the concrete solidify in a short time, and its characteristics also require its addition and mixing. It was completed in a very short period of time, and the equipment for filling the quick-setting agent with compressed air has be...

It was completed in a very short period of time, and the equipment that uses compressed air to fill the quick-setting agent has been put into use, but the overall structure is not perfect enough, and the mixing effect is not good enough.
