Description
[technical field]
The utility model relates to a kind of machinery that carries out the Drilling bolthole on the coal mine roadway rock, specifically belongs to a kind of Pneumatic anchor rod hammer drill.
[background technology]
Bolt support is an advanced technology, with its safety, economic and superiority fast, obtained generally applying in colliery tunnel support, and the bolthole Drilling is a requisite flow chart together in the whole bolt support engineering construction.At present, the related plant equipment of bolthole Drilling is looked coal mine roadway rock property, soft or hard degree difference and the tool diversity.Middle soft rock tunnel mainly uses pure swinging jumbolter to carry out the operation of Drilling bolthole, and such rig is at middle soft rock, and its boring performance can satisfy the engine request of coal mine roadway bolt support.Hard rock (f 〉=8) tunnel because pure swinging jumbolter does not have impact function, can not be used for the bolthole operation basically, and need use pusher leg drill instead.
Pusher leg drill comprises single-stage and twin-stage airleg rock drill, the single-stage airleg rock drill is little because of the flexible stroke of air leg, relative altitude is big, can only be used for the operation of level or inclination bolthole, and concerning Drilling roofbolt hole, because the Drilling hole perpendicularity does not often reach the technical requirements of bolt support, and can not use as regular roofbolt drilling machine.
The twin-stage airleg rock drill is the roofbolt hole drill cutter machinery that generally adopts at present because its complete machine height is short, flexible stroke is big, and the single-stage airleg rock drill has solved the verticality problem in Drilling roofbolt hole relatively." the twin-stage airleg rock drill " of the patent No. 91233378.2 is present more typical a kind of twin-stage airleg rock drill tools, and its structure comprises hammer drill and twin-stage air leg, and both are hinged by linkwork, form a complete twin-stage airleg rock drill.Have air-operated control valve and horizontal handgrip on the hammer drill, air leg comprises outer shell, middle cylinder, piston rod, guide pin bushing etc., paying suit by two groups of pistons forms, when air leg need extend, compressed air enters the cylinder lower end through linkwork parts, piston rod gas channel, promote inside and outside piston and move upward, realize the I and II stroke of air leg.
Existing twin-stage airleg rock drill is when reality is used, there are the following problems: (1) is when Drilling roofbolt hole, the operating personnel must stand in machine under operate, magma and rock that may inbreak can directly water pounds on one's body the operator many, the work under bad environment of potential safety hazard.(2) air leg is stretched and is fallen control assembly and all be located on the hammer drill, and machine constantly raises along with dark the increasing of bolthole cutter, and operator's hand can not touch control button, thereby also there is potential safety hazard in influence to the control of air leg.(3) present, be used for the twin-stage airleg rock drill in Drilling roofbolt hole, can only with the air leg coupling of one-way fashion, when avoiding receiving leg automatically, machine is because of unsettled and contingent accident; But, concerning the pusher leg drill of Drilling level, inclination petrosal foramen, conveniently improve operating efficiency in order to move air leg, need again and the supporting use of reversible air leg, this is a great problem that perplexs the mine working operation at present.Rigidity was relatively poor when (4) air leg stretched out, and Drilling level, inclination petrosal foramen efficient are low.
[summary of the invention]
For overcoming the problems referred to above that prior art exists, the utility model aims to provide a kind of Pneumatic anchor rod hammer drill with new structure, this machine drill is cut a hole roofbolt hole job safety, can be used with reversible air leg coupling, and under the situation that machine constantly raises along with the bolthole dark increase of cutter, the difficult problem of air leg control can not appear yet, it both can Drilling roofbolt hole, also can the Drilling level, the inclination petrosal foramen.
For achieving the above object, the utility model has adopted following technical scheme: the Pneumatic anchor rod hammer drill of this structure comprises by the hinged hammer drill of linkwork, air leg, hammer drill is provided with the air leg control valve, air leg is paid suit by piston and is formed, it is characterized in that: described linkwork is a replaceable type jointed shaft, is provided with one in the jointed shaft and connects gas circuit; Detachable has connected an air leg control arm on the jointed shaft, height after the length of described air leg control arm and air leg stretch is complementary, it by crank arm and controlling organization form, controlling organization is made of control valve and control handgrip thereof, one end of cranking arm is connected with the control valve valve body, the other end and the jointed shaft of cranking arm are hinged, and the control gas circuit in the control valve connects gas circuit through jointed shaft and connects with the hammer drill gas circuit;
Aforesaid Pneumatic anchor rod hammer drill is characterized in that: the twin-stage air leg is three cylinder barrel air legs, and it comprises connection support body, outer cylinder, one-level cylinder barrel, secondary cylinder barrel and supporting mass; The secondary cylinder jacket casing is in the one-level cylinder barrel, and the first-stage cylinder jacket casing is equipped with piston and guide pin bushing on the cylinder barrel in outer cylinder, connects support body and is located at the outer cylinder upper end, and supporting mass is contained in secondary cylinder barrel lower end.
Aforesaid Pneumatic anchor rod hammer drill is characterized in that: described cranking arm is two hollow circular-tubes that be arranged in parallel, and the hollow circular-tube two ends have connector, and connector is connected with valve body, jointed shaft respectively.
Aforesaid Pneumatic anchor rod hammer drill is characterized in that: described cranking arm is two hollow square tubes that be arranged in parallel, and hollow square tube two ends have connector, and connector is connected with valve body, jointed shaft respectively.
Aforesaid Pneumatic anchor rod hammer drill is characterized in that: described air leg control arm is connected on the jointed shaft by U-shaped pin detachable.
Compared with prior art, Pneumatic anchor rod hammer drill of the present utility model has the following advantages:
Adopt the hammer drill of the two gas circuit structures of air leg air feed, linkwork is designed to replaceable type jointed shaft structure after, can realization and the coupling application target of one-way fashion or reversible air leg by the displacement jointed shaft.After detachable was provided with the air leg control arm, during Drilling roofbolt hole, the air leg control arm can both turn to a suitable position, make the operator leave machine one segment distance, guaranteeing that magma and rock that may inbreak can not water pounds on one's body the operator, has eliminated potential safety hazard, has improved working environment.Stretch by air leg control arm control air leg and to fall, solved the problem that operator's hand can not touch the air leg control button on the hammer drill, can both air leg be fallen, do not have potential safety hazard at any working depth state.Air leg control arm, connection cover adopt quick change U-shaped pin to be connected with jointed shaft, make roofbolt hole drill cutter and group's bolthole Drilling operation, and mutual conversion is very convenient.Adopt three cylinder barrel twin-stage air legs, with the piston rod of the alternative prior art of cylinder barrel, good rigidly, when Drilling level, inclination petrosal foramen, the hammer drill performance can be not fully exerted, and rock penetration performance is higher.
