Abstract

The invention provides a lifting rotary type guniting device. The lifting rotary type guniting device comprises a lifting air cylinder, wherein the lifting air cylinder is fixed on a chassis; a supporting frame is fixed on a piston rod of the lifting air cylinder; a wear-resisting guniting head is fixed on the supporting frame; the wear-resisting guniting head is connected with a wear-resisting guniting pipe; the wear-resisting guniting pipe is connected with a guniting opening of a pneumatic guniting machine; and an air outlet of the pneumatic guniting machine is connected with an air inlet of the lifting air cylinder. Compared with the prior art, the lifting rotary type guniting device can be lifted and rotated and can be used for flexibly spraying at different heights and angles, so that the aim of safely spraying concrete in a labor-saving and time-saving manner is realized, and furthermore, the construction safety, convenience and construction efficiency are guaranteed and the aim of rapidly and efficiently constructing is realized.

Description

technical field [0001] The invention relates to a spraying device, in particular to an elevating and rotating spraying device used for construction operations of sprayed concrete support in mine roadways. Background technique [0002] As we all know, during the construction of coal mine underground roadway, due to the high spraying height of the roadway, in order to ensure construction safety, it is necessary to spray concrete on the roof to support the roof, so as to ensure construction safety. The spraying device in the prior art needs to manually hold the spray gun to spray concrete in different directions and heights, and the working environment of the workers is harsh and the work intensity is high. Therefore design a kind of lifting rotary spraying device that can adjust jetting height and angle, be the technical problem that needs to solve at present. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lift...
