Abstract

A two-handed horizontal-handled air pick, characterized in that: the horizontal hole of the coupling sleeve is connected with the vertical hole in a T-shape, the handle is inserted into the horizontal hole of the coupling sleeve and tightened, and one end of the handle is provided with a valve for opening and closing the air circuit. Pressure handle, the other end is provided with a gas circuit control valve controlled by the pressure handle, with a radial exhaust hole, and the upper part of the cylinder body with the axial return hole is screwed into the vertical hole of the coupling sleeve, and its top surface is pressed tightly on the The gas distribution mechanism in the vertical hole of the coupling sleeve is provided with a hammer body that can move up and down in the cylinder body, and a pick drill whose tip is outside the cylinder body and is acted by the hammer body. This kind of air pick uses both hands to hold both ends of the handle horizontally, and uses the principle of leverage to easily open and close the air path. The two hands work in harmony, and the operation is free, which reduces labor intensity and improves production efficiency. The air pick is simple in structure, easy to manufacture, low in cost, long in service life, good in sealing performance, reliable in operation, and expands the application range of the air pick. The small end of the hammer body of the air pick hitting the pick drill faces downward, even if the small end of the hammer body expands slightly, it will not be stuck with the inner wall of the cylinder. There is a drum-shaped rubber muffler cover in the middle of the cylinder with exhaust holes, which reduces the noise caused by the exhaust around the cylinder.

Description

Both hands transverse-gripping gas pick

Technical field the utility model relates to a kind of pneumatic tools, particularly relates to a kind of building the road, the gas pick of exploitation cubic metre of earth and stone usefulness.

The gas pick that background technology is used at present is the old product fifties mostly, shortcoming is that operator's one hand is held gas pick handle, and to overcome 3 elastic forces that spring is very strong simultaneously, firmly press the butterfly gate of controlling gas circuit, operation inconvenience, tired easily, labour intensity is big, production efficiency is low, complex structure, many, the maintenance difficult of consumable accessory.

Utility model content the purpose of this utility model is to overcome weak point of the prior art, and provides a kind of simple in structure, and is easy to operate, reduces labor intensity, and gives full play to the both hands transverse-gripping gas pick of operator's hands coordination work.This both hands transverse-gripping gas pick, it is characterized in that: the lateral aperture of coupling sleeve is T-shaped with vertical hole and connects, handgrip penetrates the lateral aperture of coupling sleeve and tightens up, one end of handgrip is provided with the pressure handle that opens and closes gas circuit, the other end is provided with the gas path control valve that is subjected to pressure handle control, have rod radial air vent, axially the cylinder body top of return-air hole is screwed in the vertical hole of coupling sleeve, its top end face clamping sleeve is contained in the valve actuating mechanism in the vertical hole of coupling sleeve, be provided with the hammer body that can move up and down in the cylinder body, and be subjected to the pick rod of the tip of tup action in the cylinder body outside.Valve actuating mechanism comprises valve gap, valve cabinet, the upper surface of valve cabinet contacts with valve gap, the lower surface is compressed by cylinder body, the slide valve buckle that has flange is contained in and radially has shoulder hole, axially have in the valve cabinet of return-air hole, the upper surface of guiding valve flange can be adjacent to the valve gap lower surface that has air admission hole, and the valve gap center of top is provided with the valve gap pad.The diameter of hammer body lower end bump pick rod part is less than the diameter of hammer body upper end targeting part.The part that the cylinder body middle part has steam vent is contained by set silencer cover, and the steam vent of silencer cover forward.The utility model compared with prior art has following advantage:

1, changing gas pick one-handed performance is bimanualness, and the horizontal two ends of shaking hands of both hands utilize lever principle easily to open and close gas circuit, hands coordination work, and operation has alleviated labour intensity freely, has improved production efficiency.

2, simple in structure, be easy to make, cost is low, long service life, good seal performance, reliable operation, the scope of application of gas pick of can enlarging.

3, the hammer body of bump pick rod is upside down little, even the hammer body microcephaly has expansion slightly, can be not stuck with inboard wall of cylinder block yet, and still can operate as normal.

4, the cylinder body middle part that has a steam vent is provided with drum type rubber silencer cover, reduced the noise that exhaust brings around cylinder body effectively, and the steam vent of rubber silencer cover forward, has eliminated the high pressure draught of being discharged by cylinder body to health effects.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment now is further described the utility model in conjunction with the accompanying drawings.With reference to Fig. 1, operator's both hands are horizontal shakes hands 1 two ends, depresses the pressure handle 2 of handgrip one end, promotes push rod 3, back down ball sealer 4, compressed air enters coupling sleeve 7 through rubber hose coupling 6, the air admission hole on valve gap 20, promoting guiding valve 9 moves down, formed gap between guiding valve and the valve gap this moment, and compressed air enters the epicoele of cylinder body 10 through the two gap of guiding valve and valve gap, promote hammer body 12 declines in the cylinder body; When hammer body is crossed cylinder body middle part steam vent, the residual air pressurized of cylinder body cavity of resorption, form air cushion, along with hammer body constantly descends, the air pressure of cavity of resorption raises, the guiding valve that gases at high pressure cooled via return air road 11 promotes to be sleeved in the valve cabinet 19 rises, be adjacent to up to guiding valve and valve gap, blocked the gas circuit that compressed air enters the cylinder body epicoele, this moment, hammer body relied on inertia still to move down at a high speed, up to bump pick rod 13, finish stroke movement; This moment, the compressed air of epicoele was discharged through the steam vent at cylinder body middle part, and the pressure of epicoele sharply descends, and hammer body rises under the effect of following cavity pressure, also relies on inertia to rise to the end of epicoele, finishes drawback movement.8 pairs on the valve gap pad that is located at valve gap central authorities has clashed into cushioning effect.Gas pick has been finished a working cycles, and the work of going round and beginning again then, and hammer body moves back and forth, and is clashing into pick rod, and pick rod digs in the hard formation, makes it be broken into piece.Unclamp pressure handle, under the effect of spring 5, ball sealer has cut off gas circuit, hammer body stop motion, power cut-off.Pick rod moves up and down in cylinder body front end lining 14, and the cylinder head outside is provided with the spring 15 that prevents that pick rod landing and pick rod from resetting, and this spring plays the effect of vibration damping again.The cylinder body middle part that has steam vent is provided with rubber silencer cover 17, and its two ends also tighten up with larynx hoop 16,18.
