Abstract
The utility model discloses a kind of coal mine gallery drilling rig gyrator chuck, comprise in cylinder body and cylinder body and pass through conical surface piston and the conical surface slips of cone match, cylinder body two ends are respectively equipped with the left end cap corresponding with conical surface slips and the hubcap corresponding with conical surface piston; Between described conical surface slips, be provided with return Compress Spring, conical surface slips outer end is provided with boss, is arranged with the butterfly spring that outer and conical surface piston end surface join on boss.The utility model is simple in structure, is convenient to dismounting and maintenance, and when use, hydraulic oil enters after the oil pocket of conical surface piston, and promotion conical surface piston promotes conical surface slips left and moves radially, and to clamp drilling rod, butterfly spring is compressed simultaneously; When oil return, under restoring force effect, butterfly spring promotes conical surface piston and moves right, thereby make conical surface slips outwards do radial motion, unclamp drilling rod, clamp with unclamp sensitive, can greatly save use cost, can effectively increase the service life, greatly enhance productivity.
Description
Technical field
The utility model belongs to colliery drilling equipment technical field, particularly a kind of coal mine gallery drilling rig gyrator chuck.
Background technology
At present, the gyrator chuck of coal mine gallery drilling rig mostly is hydraulic, wherein a class chuck comprises rubber drum, slips and hydraulic system, between slips, be provided with spring, it is during for Three-edged drill stem, exist rubber drum easily to damage defect tattered and leakage of oil, because spring is bent into arc, discontinuity, and spring opens and will overcome hydraulic oil resistance, easily occurs tired and fractures, therefore, need often to change spring and rubber drum, not only affect equipment continuous firing, and greatly increased workman's amount of labour and cost of production.
Utility model content
The utility model provides a kind of coal mine gallery drilling rig gyrator chuck of simple in structure, not fragile and long service life.
For achieving the above object, the technical solution of the utility model is: a kind of coal mine gallery drilling rig gyrator chuck, comprise in cylinder body and cylinder body and pass through conical surface piston and the conical surface slips of cone match, cylinder body two ends are respectively equipped with the left end cap corresponding with conical surface slips and the hubcap corresponding with conical surface piston; Between described conical surface slips, be provided with return Compress Spring, conical surface slips outer end is provided with boss, is arranged with the butterfly spring that outer and conical surface piston end surface join on boss.
Described butterfly spring is at least a pair of, and the interior edge of every pair of butterfly spring joins, and the outer and the conical surface piston end surface that are positioned at inner butterfly spring join, and the outer and the left end cap inner face that are positioned at outside butterfly spring join.
Described conical surface outside piston side face is provided with the guidance tape joining with inboard wall of cylinder block.
Between described conical surface outside piston side face and inboard wall of cylinder block, be provided with exterior seal ring, between conical surface piston inner peripheral surface and hubcap, be provided with inner seal ring.
Compared with prior art, the utility model has the advantages that:
1, the utility model comprises cylinder body and interior conical surface piston and the conical surface slips of cone match of passing through of cylinder body, and cylinder body two ends are respectively equipped with the left end cap corresponding with conical surface slips and the hubcap corresponding with conical surface piston; Between described conical surface slips, be provided with return Compress Spring, conical surface slips outer end is provided with boss, is arranged with the butterfly spring that outer and conical surface piston end surface join on boss, and it is simple in structure, be convenient to dismounting and maintenance, when use, hydraulic oil enters after the oil pocket of conical surface piston, promotes conical surface piston and is moved to the left, and then promote conical surface slips by the conical surface and move radially, to clamp drilling rod, meanwhile, butterfly spring is compressed; When oil return, under restoring force effect, butterfly spring promotes conical surface piston and moves right, thereby makes conical surface slips outwards do radial motion, unclamp drilling rod, clamping force is large, clamp with unclamp sensitive, except conical surface slips, there is not other consumable accessory, can greatly save use cost, can effectively increase the service life, greatly enhance productivity.
2, butterfly spring is at least a pair of, the interior edge of every pair of butterfly spring joins, and the outer and the conical surface piston end surface that are positioned at inner butterfly spring join, and the outer and the left end cap inner face that are positioned at outside butterfly spring join, butterfly spring is stressed evenly, be quick on the draw, and reliability is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Coal mine gallery drilling rig gyrator chuck as shown in Figure 1, it comprises the conical surface piston 10 and conical surface slips 3 by cone match in cylinder body 6 and cylinder body 6, between conical surface slips 3, be provided with return Compress Spring 11, the outer circumference surface of conical surface piston 10 is provided with the guidance tape 5 joining with cylinder body 6 inwalls.Be respectively equipped with the left end cap corresponding with conical surface slips 31 and the hubcap 7 corresponding with conical surface piston 10 at cylinder body 6 two ends, between the inwall of the outer circumference surface of conical surface piston 10 and cylinder body 6, be provided with exterior seal ring 8, between the inner peripheral surface of conical surface piston 10 and hubcap 7, be provided with inner seal ring 4, make to form confined space between conical surface piston 10 right-hand members and hubcap 7.
Be provided with boss 9 in the left part of conical surface slips 3, on boss 9, be arranged with a pair of butterfly spring 2, the interior edge of every pair of butterfly spring 2 joins, and is positioned at the outer of inner butterfly spring and the left side of conical surface piston 10 joins, and is positioned at the outer of outside butterfly spring and the inner face of left end cap 1 joins.
The utility model operating principle is: hydraulic oil enters after the oil pocket of conical surface piston 10, promotes conical surface piston 10 and is moved to the left, and then promote conical surface slips 3 by the conical surface and move radially, and to clamp drilling rod, meanwhile, butterfly spring 2 is compressed; When oil return, under restoring force effect, butterfly spring 2 promotes conical surface piston 10 and moves right, thereby makes conical surface slips 3 outwards do radial motion, unclamps drilling rod.
The utility model is applicable to the coal mine gallery drilling rig of various models.
Be not limited to above-mentioned embodiment, the butterfly spring 2 in the utility model can be set to multipair according to actual needs, for example: 2 pairs, 3 pairs, 5 pairs or 8 pairs.
