Bolt support is a kind of its support reinforcement mode that adopts in the underground chamber constructions such as the earth's surface engineering such as side slope, ground deep foundation ditch and tunnel, stope.Make roofbolt with metalwork, wooden part, polymer member or other materials, squeeze in earth's surface rock mass or chamber surrounding rock body pre-drilled hole, utilize the special tectonic of its head, the body of rod and afterbody supporting plate (also can), or depend on cohesive action country rock and rock mass stability are combined and produce suspension effectiveness, compound beam effect, reinforcing effect, to reach the purpose of supporting.Bolt support can prevent that country rock from forming larger plastic zone and loosening district, the reduction process of slowing down the tunnel-surrounding country rock, and the safety of raising underground work reduces the number of times of acting as a planted agent in the tunnel, reduces the cost of production of coal mining enterprise.
Jumbolter is a kind of common rig in coal industry, and it mainly utilizes hydraulic support to drive motor to carry out boring work at roadway top, colliery, with convenient fixedly top board, skyhook, prevents that the roadway top from caving in, and increases roadway use safety.Jumbolter is in boring procedure, and the motor height can be adjusted at any time along with the flexible of hydraulic support, and the bottom of jumbolter directly is supported on roadway ground, to keep the balance of jumbolter, guarantees that boring procedure carries out smoothly.But can not beat deep hole in the bottom, tunnel in existing jumbolter, bring adverse effect for carrying out of support work of bottom, tunnel.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of and compares with existing jumbolter for make the pneumatic anchor hole rig of single leg support pillar of anchor hole in the bottom, tunnel, have simple to operate, conveniently moving, the characteristics of high efficiency.
The technical solution of the utility model is: a kind of trestle type pneumatic anchor hole rig, comprise a support, and this support front end is provided with top, and described support side is provided with a plurality of slide blocks, and described slide block and a slide rail are slidably matched; Described slide rail opposite side is equipped with air leg and hammer drill; Described support tail end is equipped with a telescopic support cylinder barrel, and this support cylinder barrel is provided with support control valve and rapid-release valve, and this support control valve is connected with the gas motor by sebific duct.
As the further improvement of such scheme, described hammer drill comprises reversal valve, admission valve group, rotating mechanism, gas motor and noise damper, and described hammer drill is slidably matched by support and described slide rail; Described rotating mechanism front end is provided with tool joint, and described reversal valve is connected with described air leg, and described gas motor is provided with motor control valve, this motor operated valve by sebific duct respectively with described support control valve be connected the control valve of air leg and be connected.
Further improvement as such scheme, the described air leg outside is provided with lug, has a through hole on this lug, evenly has a plurality of locating holes on described slide rail, described air leg is by being screwed positioning bolt in this lug through hole, thereby will self be fixed on described slide rail.
As the further improvement of such scheme, described gas motor adopts gear type gas motor.
Principle of the present utility model is: support can be easily contact with the roadway top and with roadway top fixed support, can guarantee the stability of jumbolter in boring procedure; There are enough space jointed rods the hammer drill below, and air leg utilizes the compressed air pushing piston, piston termination strike drill steel tail end; Simultaneously, reciprocating motion of the pistons interlock rotating mechanism drives drill steel and rotates, and by hitting and rotating, makes it possess rock drilling function preferably.
The utility model has the advantage of: (1) rig total arrangement is reasonable, adopts Split type structure, convenient in carrying; Compact integral structure, volume is little, weight is moderate.(2) this rig adopts telescopic support cylinder barrel, can rise to rapidly top plate supporting firm.(3) this rig gear type gas motor is strong and powerful, and output torque is large, and running is stable, and reliability is strong.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the structural representation of air leg of the present utility model and hammer drill,
Fig. 3 is gas circuit control principle drawing of the present utility model.
[specific embodiment]
