Description

Pneumatic anchor rod anchor cable rig

The utility model relates to the machinery of a kind of colliery roadway suspension roof support engineering construction.Be specifically related to a kind of Pneumatic anchor rod anchor cable rig.It is the special-purpose rig of a kind of Pneumatic rotary.

At present, the jumbolter in the brill roofbolt hole of domestic use has electric rotary-type, hydraulic rotary, Pneumatic rotary and pneumatic rotary impact type etc.Wherein the structure of Pneumatic rotary jumbolter is the monomer gas leg type, and its rotary cutting power is provided by the gas motor, and the feeding of drilling is finished by flexible big cylinder diameter air leg, and the power of its gas motor and air leg is all down-hole compressed air.The gas motor has two kinds of gear type and plunger types.No matter be the jumbolter that adopts gear type gas motor or adopt piston air motor, all can only bore bolthole or anchor cable hole, generally can not stir anchorage cable anchoring agent and skyhook, anchor cable.In addition, what be provided with in the body is single air circuit, and rig falling speed is slow, and the rig subsidiary operation time is many, and operating efficiency is low.

The purpose of this utility model is to provide a kind of bolthole or anchor cable hole of not only boring, and can also stir anchorage cable anchoring agent, installing resin anchor rod, anchor cable, and the high Pneumatic anchor rod anchor cable rig of operating efficiency.

The purpose of this utility model is achieved in that a kind of Pneumatic anchor rod anchor cable rig, comprise gas motor, reduction box, body, air leg, control arm, hydroecium and drill bushing, gas motor and reduction box are assembled into head, head is fixed on the body, air leg and body are mounted to one, control arm is connected body one side, hydroecium is sleeved on the interior output shaft of reduction box, drill bushing is connected the reduction gearbox output shaft end, internal body is provided with double gas gas circuit, the gas circuit air inlet links to each other with air cavity in the body, and exhaust outlet communicates with atmosphere.Motor is given drilling rod, drill bit by reduction box with transmission of power, finishes the broken rock of rotary cutting, and the cutting feed motion is finished by air leg, and broken rock of rotary cutting and cutting feed motion power are all from down-hole compressed air.

Insert anchor pole or anchor cable erector in the drill bushing of the present utility model.

Compare with existing pneumatic roof bolter, the utlity model has following advantage:

1, designed double air circuit in the body, it is fast that rig falls speed after rise, reduces the rig subsidiary operation time, improves operating efficiency.

2, be connected with anchor pole or anchor cable erector on the drill bushing,, also can stir anchoring agent, installing resin anchor rod or anchor cable simultaneously so this machine not only can bore bolthole or anchor cable hole.

Below in conjunction with accompanying drawing the utility model is described in further detail:

As Fig. 1, the utility model is a kind of Pneumatic anchor rod anchor cable rig.Form by critical pieces such as gas motor 3, gear reduction box 2, body 4, big cylinder diameter air leg 7, control arm 6, pintle 5, hydroecium 1 and drill bushings 11.

As Fig. 2-4, gear reduction box 2 is assembled into head with gas motor 3 by the position of engagement of two pairs of

gear pairs

14,15 and by gear box casing 9 gentle motor shell 8 usefulness bolts, and head is fixed by bolts on the body 4 by gas motor shell 8 again.Air leg 7 is mounted to one by flange 18 usefulness bolts and body 4.Axle sleeve on 6 of control arms pass through pintle 5 and insert body 4 is connected with body.Parts such as head, air leg, control arm are assembled into one by body and pintle.1 cover of hydroecium is pressed in the top of output shaft 13 in the gear reduction box 2.With the drill bushing 11 that is threaded, drilling rod inserts in the drill bushing 11 and get final product at the output of output shaft 13, and rock is cut brokenly in transmission rotating speed and torque.

As Fig. 5,6,7, body 4 inside are provided with double gas gas circuit 32, and double gas gas circuit air inlet links to each other with air cavity in the body 4, and exhaust outlet communicates with atmosphere.

As Fig. 8,9,10, concrete structure functions such as gear type gas motor, big cylinder diameter air leg, control arm and double gas circuit can illustrate by the operating process of operation rig.During boring, operator's both hands are shaken hands respectively 19,23, with the right hand trigger 20 of holding with a firm grip, under the trigger lever effect, motor control valve spool 25 is opened in push rod 24 reaches, compressed air then enters motor control valve by air inlet and enters motor through pintle and body 4, flexible pipe, and motor driving gear 16 is rotated, and drives driven gear 17 and motor output shaft rotation.And, give output shaft 13, thereby drive drilling rod, the broken rock of drill bit rotary cutting with rotating speed and transmission of torque by after the two-stage gear reduction in the gear-box.Clockwise direction twisting knob 22, by the inclined-plane on the knob push rod 27 is moved forward, air leg control valve 30 is opened, and compressed air i.e. internal channel on air leg control valve, pintle, body and dual-purpose valve 31 (Fig. 5) enters air leg, air leg is stretched out do the feed motion of rig boring.Change the position of operation knob 20 and knob 22, can adjust the air inflow of two valves, thereby change the fltting speed of rig output speed and air leg.Be rotated counterclockwise knob 21, the same knob inclined-plane that passes through is with push rod 26 reaches, water control valve 28 is opened, down-hole static pressure water by water inlet through water valve 28, pintle, body and advance high-pressure hose and enter hydroecium 1, hydraulic gland 12 is installed in the hydroecium body, the inside and outside twice waterstop ring that is provided with respectively at hydraulic gland, after water for dust removal enters hydroecium, promptly enter the output shaft endoporus by aperture, enter rod bit, the heat that produces in the time of can taking away the drill bit drilling first, moreover can wash away the landwaste of drilling, make wet boring and use.Trigger 20 is resetted, and motor is stall, and handle 22 resets, and rig is under the deadweight effect, and the air leg compressed air is then discharged from exhaust outlet fast by the double gas circuit on the body, and air leg is regained, and rig falls after rise, promptly finishes whole boring procedure.

From Fig. 3 as seen, an one-way clutch 10 is installed on gear-box inner main axis 13, this clutch can only folk prescription to rotation, oppositely self-locking.Under the overload situation, all self-lockings of clutch both direction must not be rotated in boring procedure or in the skyhook, and the protection rig is injury-free.

Figure 11 is stirring skyhook of the present utility model or anchor cable erector structure chart.Shapes are square, hexagon or spirality in the erector 33, and the profile below is a hexagon.The utility model rig can be finished the work of skyhook or anchor cable and stirring anchor pole or anchorage cable anchoring agent fast with it, and its performance can illustrate by install operation process.After rig is finished boring, put down drilling rod, boring is gone in the resin anchoring agent package, with anchor pole or anchor cable the anchoring agent is headed in the hole, the other end of anchor pole or anchor cable inserts in the erector, and shape is square in the bolt installer, shape is a spirality in the anchor cable erector, matches with anchor pole or steel strand rope.Profile below be a hexagon, and anchor pole or outer six sides of anchor cable erector are inserted in the drill bushing, starts rig, makes the rotation of anchor pole or anchor cable, thus quick agitating resin anchoring agent, wait the anchoring agent fully to stir after, close rig.This moment, anchoring agent roll was solidified gradually, and anchor pole or anchor cable and resin are integral admittedly, and anchor pole or rigging have had first anchor-hold, tighten ground tackle again, finish anchor pole or anchor cable mounting process.
