Abstract
The utility model relates to a self-locking hoisting implement for lifting shafts, which comprises a hoisting seat body, an upper and a lower pressing covers, a spacing sleeve, and a lifting ring; the upper pressing cover, the spacing sleeve, and the lower pressing cover are respectively screwed with the hoisting seat body; walls of the spacing sleeve form a plurality of cylindrical opening slots which are inserted in inner holes of the hoisting seat body; top rods are fastened on the upper pressing cover through each corresponding opening slot and through holes of the upper pressing cover, and springs which are sheathed on tappet rods are arranged between the upper pressing cover and tappet columns; steel balls are arranged between the opening slots under each tappet column and each convex column of the lower pressing cover. The utility model has the advantages that reliable locking clamp and easy release can be realized through an axial movement of the steel balls in a cone surface of the hoisting seat body, and the work efficiency and the reliability of hoisting can be enhanced.
Description
The utility model relates to a kind of suspender, relates to a kind of suspender of suspension shaft class part specifically.
Axially lifting by crane tubulose or axial workpiece,, need guarantee that suspender is to there being enough gripping powers by hanging piece at present in order reliably to lift by crane; And this gripping power is that the people is for carrying out.But the size of gripping power is difficult for accurately regulating, and is perhaps too small or excessive, and this will inevitably cause by the slippage of hanging piece or produce impression, and its result causes lifting dangerous or damage by hanging piece.And, owing to be artificial adjusting, very waste time and energy.
Therefore, the purpose of this utility model provides a kind of quick and suspender of failure-free suspension shaft class part.
For achieving the above object, the utility model provides a kind of self-locking type suspender of suspension shaft class part, and it comprises: a flap seat body with cone-shaped endoporus, be formed with endoporus last lower cover, be arranged on the spacer that is formed with endoporus between upper press cover and the flap seat body and pass upper press cover and the through hole of spacer and be screwed onto suspension ring on the flap seat body; Upper press cover and spacer and lower cover are screwed onto respectively on the flap seat body; Spacer has axially extended wall, forms several cylinder open grooves on wall, and described wall is inserted in the endoporus of flap seat body; Lower cover is set in and is fixed on the flap seat body screwing and can moves back and forth with respect to the flap seat body, lower cover be formed with upward axis to the projection that stretches out with the cone-shaped endoporus that stretches into the flap seat body in; The push rod of being made up of tappet and tappet passes cooresponding each open slot and upper press cover through hole, and the tappet end is fixed on and covers, and a spring housing is located on the tappet and supports and is located between loam cake and the tappet; Between described open slot under each tappet and lower cover projection, steel ball is set.
Adopt said structure of the present utility model, when hung in regulation axle class part in the diameter range from lower cover when the upper press cover direction is inserted the suspender endoporus, steel ball upwards moves along the inclined-plane of flap seat body until the steel ball circumference external diameter of engagement shaft class part just from its nethermost reference position, make length of spring compressed prop up steel ball to produce predetermincd tension simultaneously, steel ball is the lifting force of suspender with being enough to lock the required self-locking gripping power of suspender counter motion by the generation of the closed contact of hanging axis class part circumference.The size of this self-locking gripping power changes with axle class part deadweight size variation.Like this, need not the size of manual shift gripping power, avoided causing by the slippage of hanging axis because of artificial adjusting gripping power is improper or producing impression, thereby guaranteed the reliability of suspender clamping lifting.After lifting job is finished, under non-loaded situation on the suspension ring of suspender, hold up lower cover manually, make steel ball and broken away from by hanging axis, self-lock force promptly disappears, and like this, suspender can be along oppositely withdrawing from by hanging axis class part.So realize by the reliable grip of hanging piece with easily discharge, with high efficiency with finish whole lifting process reliably.
Below in conjunction with accompanying drawing a preferred embodiment of the present utility model is specifically described, understands the purpose of this utility model and characteristics with further.

As shown in the figure, the self-locking type suspender of suspension shaft class part of the present utility model comprises: have the flap seat body 5 of cone-shaped endoporus 17, respectively be formed with endoporus 18,19 last lower cover 3 and 6, be arranged on the spacer that is formed with endoporus 20 4 between upper press cover 3 and the flap seat body 5 and pass upper press cover 3 and the through hole of spacer 4 35,21 and be screwed onto suspension ring 15 on the flap seat body 5; Upper press cover 3 passes through hole 22,23 by screw 1 respectively with spacer 4 captives joint with the screw 24 of flap seat body 5, supporting one cover 9 between the through hole 26 of lower cover 6 and the counterbore 25 of flap seat body 5, cover and 26 of through holes have certain interval, so that lower cover can move back and forth on cover 9, between the upper surface of cover 9 counterbore 27 and lower cover 6 on the cover periphery a sheathed spring 10, it has been to support the effect that cushions; Spacer 4 has axially extended wall 29, forms cylinder open groove 30 on wall 29, and described wall 29 is inserted in the endoporus 17 of flap seat body; Lower cover 6 has the projection 34 that protrudes upward, these projections stretch into the cone-shaped endoporus 17 of flap seat body 5, several push rods of being made up of tappet 31 and tappet 32 11 pass the through hole 33 of corresponding opening groove 30 and upper press cover 3, the tappet end is fixed on the loam cake 3 by a back-up ring 13, another spring 12 be set on the tappet 31 and support the lower surface that is located at upper press cover 3 and and tappet 32 upper surfaces between; Between the projection 34 of described open slot 30 under each tappet 32 and lower cover 6, steel ball 14 is set.Corresponding in the present embodiment through hole 22,23,33,26, counterbore 25,27, screw 24, push rod 11, cover 9, spring 10,12, projection 34 and steel ball 14 numbers are six, and the suspension ring 15 of setting are two, as shown in the figure.These parts can also be arranged to other number.The effect of its medi-spring 12 is to produce predetermincd tension to prop up a class part 16, so also can be adapted at horizontal direction with the axle class part suspender of packing into.
As shown in the figure, when with axle class part 16 from lower cover 6 to upper press cover 3 directions are inserted endoporus, make steel ball 14 along the inner hole cone of flap seat body towards moving until engagement shaft class part circumference external diameter, make spring 12 produce predetermincd tension and prop up steel ball 14, at this moment, steel ball 14 closed contact axle class parts 16 peripheries produce that to be enough to lock the required self-locking gripping power of suspender reversing sense motion be the lifting force of suspender.The size of self-locking gripping power is to change voluntarily with the size variation of axle class part 16 deadweights, need not the size of manual shift gripping power, has therefore avoided the slippage of axle class part 16 or has produced impression.Thereby guaranteed the reliability of suspender clamping lifting.And the shirking as long as be manually to hold up lower cover 6 under the non-loaded situation steel ball 14 and axle class part 16 are broken away from suspension ring of suspender, suspender can withdraw from along the direction of lower cover to upper press cover.Therefore lifting and release are very reliable and quick, have improved safety and work efficiency.
