Description

Wet-type patching machine under the coal mine

Technical field

The utility model relates to the equipment of sprayed mortar in a kind of tunnel, is specially Wet-type patching machine under a kind of coal mine.

Background technology

Bolt support is an important support technology of well lane engineering, and particularly in recent years, combined bolting and shotcrete is generally applied in the China's coal-mine tunnel.Sprayed mortar is the important component part of bolt support.Present domestic colliery whitewashing is to do (tide) pressure spray process, the capital equipment of doing the use of (tide) pressure spray process is a pulp shooting machine, utilize high-pressure blast that concrete drier is delivered to shower nozzle, by pressure it is ejected into drift section then, this technology exists that concrete quality is wayward, rebound degree is high, dust concentration is difficult to reach problems such as coal mining enterprise's operation place occupational health standard greatly, and mostly be manually-operated, labour intensity is very big.

The use because above shortcoming, dried (tide) pressure spray process have been under an embargo in constructing tunnel also has substituted trend in the coal mine roadway construction.What replace dried (tide) pressure spray process is the wet shotcrete technology concrete technology.In constructing tunnel, adopt wet shot machine, shotcrete robot and commercial concrete, realized the mechanization of spray operation.Because the coal mine roadway section is little, can not commodity in use concrete (having the flame proof problem), bring very big difficulty for the development of spouting plant.Be not fit to the wet type spouting plant that use in the colliery at present, this also is that one of reason of dried pressure spray process is adopted in the colliery.

Summary of the invention

The utility model provides Wet-type patching machine under a kind of coal mine in order to solve the whitewashing problem that exists in the existing mine bolt support technology.

The utility model is realized by following technical scheme, Wet-type patching machine under a kind of coal mine, structure comprises the support that has creeper undercarriage, support is provided with concrete pump and guide rail, the cement cylinder of concrete pump and very heavy being located between two crawler belts, guide rail is provided with reciprocal arm, be hinged with joint piece on the piston rod of reciprocal arm, be connected with big arm swing oil cylinder between reciprocal arm and the joint piece, be hinged with big arm on the joint piece, be connected with big arm between joint piece and the big arm and face upward the oil cylinder of bowing, big arm upper end is provided with telescopic arm, the telescopic arm upper end is connected with the spray gun rotary cylinder, spray gun rotary cylinder front end is connected with the spray gun oscillating cylinder, and spray gun rotary cylinder front end is connected with support by screw swinging mechanism, and hinge has picture circle motor on the support, draw the shower nozzle that the circle motor connects and the wet shot pump is communicated with, also be connected with the spray gun oscillating cylinder between support and the picture circle motor.

Wet-type patching machine and wet type shotcreting process under the coal mine of Robot actions spray gun described in the utility model relatively have following advantage with dried (tide) pressure spray process:

1, concrete quality is easy to control.Wet shot in situ preparation concrete, proportioning, water/binder ratio can accurately be controlled, and force to stir, and concrete quality is good.2, rebound degree is lower.The concrete preparation quality of wet shot is good, the rapid hardening dose controlled, and rebound degree is lower.3, eliminate the other dust of machine substantially, greatly reduced nozzle place dust concentration.4, adopt manipulator to replace the manually-operated spray gun, reduced labour intensity, improved ejection efficiency and quality.
