Description
Technical field
The utility model belongs to colliery drilling equipment technical field, relates to a kind of chuck, 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, and its structure comprises by the conical surface piston of cone match and conical surface slips in cylinder body and cylinder body, and cylinder body two ends are provided with end cap, be provided with back-moving spring between conical surface slips, the boss of conical surface slips is arranged with butterfly spring; The piston oil pocket of most of chuck leads directly to the online bolt hole that online end cap is arranged, and when chucking work, hydraulic oil easily oozes out through screwed hole and causes leakage of oil.
Utility model content
The purpose of this utility model is to provide that a kind of structure is simple, the coal mine gallery drilling rig gyrator chuck of good airproof performance.
For achieving the above object, the utility model is by the following technical solutions: a kind of coal mine gallery drilling rig gyrator chuck, comprise the left end cap at cylinder body and cylinder body two ends and online end cap, online end cap is provided with online bolt hole, piston and conical surface slips is provided with in cylinder body, conical surface slips is provided with back-moving spring, and online bolt hole is blind hole; Be provided with piston oil pocket between online end cap and piston, online end cap offer the oil-in and high-pressure oil duct that are communicated with piston oil pocket.
Conical surface slips is single conical surface slips.
Disk spring is provided with between conical surface slips and left end cap.
Be provided with exterior seal ring between the outer circumference surface of piston and inboard wall of cylinder block, between the inner peripheral surface of piston and online end cap, be provided with inner seal ring.
Compared with prior art, the beneficial effects of the utility model are as follows: adopt online end cap to be provided with online bolt hole into blind hole, concurrent connections end cap is also provided with the oil-in and high-pressure oil duct that coordinate with piston oil pocket, avoid the hydraulic oil in oil pocket to cause leakage oil condition through bolt hole, enhance the sealing performance of chuck.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the sectional structure schematic diagram in A-A direction in Fig. 2;
Fig. 4 is the sectional structure schematic diagram in B-B direction in Fig. 2.
Detailed description of the invention
A kind of coal mine gallery drilling rig gyrator chuck, as Figure 1-4, comprise left end cap 2 and the online end cap 1 at cylinder body 3 and cylinder body 3 two ends, online end cap 1 is provided with online bolt hole 6, online end cap 1 is provided with dowel hole 4, be provided with piston 8 and conical surface slips 12 in cylinder body 3, conical surface slips 12 is provided with back-moving spring 11, and online bolt hole 6 is blind hole; Be provided with piston oil pocket 14 between online end cap 1 and piston 8, online end cap 1 offers the oil-in 5 be communicated with piston oil pocket 14 and high-pressure oil duct 13; Conical surface slips 12 is single conical surface slips; Disk spring 10 is provided with between conical surface slips 12 and left end cap 2; Be provided with exterior seal ring 9 between the outer circumference surface of piston 8 and cylinder body 3 inwall, between the inner peripheral surface of piston 8 and online end cap 1, be provided with inner seal ring 7.
During work, after hydraulic oil enters piston oil pocket 14 by oil-in 5 and high-pressure oil duct 13, promote piston 8 and move, piston 8 conical surface promotes conical surface slips 12 and does radial motion, clamping drilling rod; During oil return, disk spring 10 promotes piston 8 and moves, and conical surface slips 12 does radial motion and unclamps drilling rod under back-moving spring 11 acts on.
