Abstract
The utility model discloses a gas filler for anchor drill. Two O-shaped sealing rings (14), (16) and the gas valve core (3) of the spring (2) are arranged inside a gas valve body (1); the right end of the gas valve core (3) is provided with screw threads which pass through a gas valve end cover (4) and are connected with a screw hole pin (5) arranged in the longitudinal hole of a gas valve draw rod (6); the gas valve end cover (4) is fixed on the gas valve body, pressing a spring tightly; a positioning screw (8) arranged inside a screw hole pin (5) is used for fixing the position of the gas valve core and the gas valve draw rod; the right end of the gas valve draw rod is connected with a gas valve handle (11); when the gas valve handle is pulled, the gas valve draw rod and the valve core move relatively to the gas air valve body, and the gas valve is opened so as to supply gas to a pneumatic motor; when operators release the gas valve handle, the gas valve core resets because of the action of the spring, and the motor stops working. The utility model has the advantages of better safety and flexible operation; when the operators release the gas valve handle accidentally, the gas supply stops, the pneumatic motor stops rotating, and a drilling machine stops working; the rotary speed of the motor can be controlled.
Description
Technical field
The utility model relates to rig, refers to especially a kind ofly be used for that coal mine roadway two is helped and the anchor pole of base plate, the boring of cable bolting and the gas supply mechanism of erection unit.
Background technique
In recent years, the colliery is extensively promoted bolt support technology and has been obtained good result.Roofbolt adopts pneumatic roof bolter to finish boring and anchor pole installation exercise more, and electric coal drill is used in the two anchor pole operations of helping, and make working surface power not single, and operating speed is slow, can not bore darker anchor cable hole.Model utility ZL03 2 45384.1 disclosed group anchor cable rigs have solved the problems referred to above to a certain extent.This group anchor cable rig mainly comprises: frame, power mechanism and actuator.Frame is I-shaped, and both sides are handrail, and water supply control switch and air feed control switch are arranged between handrail and the power mechanism, respectively the break-make of control water supply and air feed.The break-make of ball valve control air feed is adopted in this design, and ball valve has only two working positions of open and close, can not control the flow of pressurized gas, therefore operator can not control the rotating speed of motor, simultaneously, and when operator's accident is loosed one's grip, rig continues rotation, is unfavorable for operator's safety.
Summary of the invention
To be solved in the utility model is in the existing group anchor cable rig, the rotating speed control problem of motor and the safety issue of operation.
The technical solution of the utility model: on the basis of model utility ZL03 2 45384.1, its air feed control switch is improved, form new air feed control mechanism, this mechanism comprises: air valve body, gas valve core, spring, air valve end cap, seal ring and air valve handle.
Gas valve core with two " O " shape seal rings and spring is installed in air valve body inside; The right-hand member of gas valve core passes the air valve end cap, the air valve end cap is fixed on the air valve body holddown spring with screw; Under the effect of spring, the cone match of the gentle valve interior wall of " O " shape seal ring on the gas valve core left end conical surface keeps sealing; The right-hand member of gas valve core is threaded with the screw pin in the transverse holes of air valve pull bar, between the right-hand member helical thread portion of gas valve core and the transverse holes of air valve pull bar bigger gap is arranged.Positioning screwn is installed in vertical screw of screw pin; The right-hand member of air valve pull bar links to each other with handle with air valve by pin.Air valve body is fixed on the I-shaped frame of rig with clip, and its import and export connect source of the gas and pneumatic motor.When pulling air valve handle, air valve pull bar pulling gas valve core leaves the air valve body conical surface, and pressurized gas opening thus passes through air valve along the direction of arrow, supplies with pneumatic motor, by regulating the pulling amplitude of air valve handle, the flow of control pressurized gas, the rotating speed of control motor.When unclamping the air valve handle, because the effect of spring, gas valve core automatically resets, and air feed is blocked, and motor quits work.
The beneficial effect that the utility model compared with prior art has: this control mechanism Security is better, and when operator's accident was unclamped handrail, air feed stopped automatically, and pneumatic motor stops operating, and rig quits work; In addition, flexible operation can be controlled the rotating speed of motor.

Embodiment
Below in conjunction with accompanying drawing mode of execution of the present utility model is described further:
A kind of gas supply mechanism of helping the anchor cable rig comprises: air valve body 1, spring 2, gas valve core 3, air valve end cap 4, screw pin 5, air valve pull bar 6, positioning screwn 8, " O " sealing shape circle 14,15,16 and air valve handle 11.
The right-hand member of gas valve core 3 is provided with a seal groove and a boss, and in order to " O " shape seal ring 14 and spring 2 to be installed, the middle part of gas valve core 3 also is provided with a seal groove, the sealing when " O " shape seal ring 16, two seal rings being installed being used for air valve and opening and close; The right-hand member of gas valve core 3 has screw thread, is used for being connected with the horizontal screw of screw pin 5.
Establish seal groove on the air valve end cap 4, seal ring 15 is installed in the groove, be used for the sealing between air valve end cap 4 and the air valve body 1.
The left end of air valve pull bar 6 is established a vertical hole and a transverse holes, vertically in the hole screw pin 5 is installed, and vertically the gap of hole and screw pin 5 is a.
The right-hand member of gas valve core 3 is threaded with screw pin 5 in the transverse holes of air valve pull bar 6, between the right-hand member helical thread portion of gas valve core 3 and the transverse holes of air valve pull bar 6 bigger gap b is arranged.
Air valve pull bar 6 right-hand members link to each other with air valve handle 11 by pin 10, and the air valve handle is connected on the frame by pin 9.
When pulling air valve handle 11, air valve handle 11 rotates around pin 9, by 6 swings to the right of the fixed 10 pulling air valve pull bars of pin, because gap a and b exist, 2 relative air valve body 1 translations to the right of screw pin (5) pulling gas valve core 3 pressure springs are opened air valve, pressurized gas enters from air inlet turning gland 7, by air valve, supply with pneumatic motor along the direction of arrow, the motor rotation; By regulating the pulling amplitude of air valve handle 11, can control the flow of pressurized gas, thus the rotating speed of control motor.
When unclamping air valve handle 11, because the effect of spring 2, gas valve core 3 automatically resets, and air feed is blocked, and motor quits work.Make the Security of rig better like this, when operator's accident was unclamped handrail, air feed was closed automatically, and pneumatic motor stops operating, and rig quits work; In addition, the operator can arbitrarily control the rotating speed of motor by the amplitude of control pulling air valve handle.
