Abstract
The utility model relates to an integral screw thread driven friction brake hoister, comprising a reel 4 and a main shaft 12. The reel 4 is sheathed on the main shaft 12; an internal gear 5 which is connected to the reel 4 is connected with a pinion 16, and the pinion 16 is connected with the main shaft 12 through screw threads; on side of the pinion 16 is orderly adjacent to a friction plate 20, a ratchet wheel 21 and a friction plate 23, the friction plates 20, 23 are in key connections with the main shaft 12, the ratchet wheel 21 is matched with a ratchet pawl 24 which is arranged on a fixed supporting base 15. The utility model has the advantages of small size, self-locking at any time, safety, etc.
Description
The utility model relates to a kind of winding plant, and particularly a kind of built in type screw drive friction braking winch mainly is applicable to lifting of goods.
Existing hoisting winding structure is: have a reel to be fixed on the main shaft, main shaft and speed reduction gearing join, and reel also is connected to a brake gear.When the motor-driven speed reduction gearing is worked, just can drive main shaft and reel and rotate, rope is wrapped on the reel, the landing goods.The winch of this structure has the shortcoming that volume is big, loosely organized, self-locking performance is poor, safety rate is low.
The purpose of this utility model be to overcome the deficiency of above-mentioned prior art and provide a kind of volume little, at any time can self-locking, built in type screw drive friction braking winch that safety rate is high.
The utility model above-mentioned purpose realizes by following technological means: a kind of built in type screw drive friction braking winch, it comprises reel 4, main shaft 12, reel 4 is sleeved on the main shaft 12, be connected to inner gear 5 on the reel 4, inner gear 5 is connected with miniature gears 16, miniature gears 16 is threaded with main shaft 12, one side of miniature gears 16 is adjacent with friction lining 20, ratchet 21, friction lining 23 successively, friction lining 20,23 is connected with main shaft 12 keys, ratchet 21 and ratchet 24 couplings, ratchet 24 is contained on the fixed mounting base 15.
Be provided with bearing 14 between described fixed mounting base 15 and the main shaft 12, be provided with bearing 18 between fixed bearing block 15 and the right supporting 19, right supporting 19 is joined with reel 4, and fixed mounting base 15 joins with front end cover 13, front end cover 13 is connected to overcoat 3, and overcoat 3 other ends and rear side housing 27 join.
Built in type screw drive friction braking winch provided by the utility model compared with prior art have little, the rational in infrastructure compactness of volume, at any time can auto lock, the safety rate advantages of higher.
Introduce the utility model specific embodiment in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model example structure scheme drawing.
As shown in the figure: 12 is main shaft, is with steel bushing 11 on the main shaft 12, the steel bushing 11 outer supporting sleeves 10 that are with, supporting sleeve 10 outer rear side housing 27 and the reels 4 of being with.Supporting sleeve 10 is connected with rear side housing 27 screws, and rear side housing 27 is connected with front end cover 13 by overcoat 3 and forms a housing.Right-hand member at this housing inner drum 4 fixedly is connected to an inner gear 5, and inner gear 5 is by transition gear 6 and miniature gears 16 couplings.The axle bolt 9 of transition gear 6 is contained on the fixed mounting base 15, is connected with bolt 17 between fixed mounting base 15 and the front end cover 13.The side of inner gear 5 is provided with a right supporting 19, and described reel 4, inner gear 5, right supporting 19 are by bolt together.Miniature gears 16 is threaded with main shaft 12.The limit, left side of miniature gears 16 is adjacent with friction lining 20, ratchet 21, friction lining 23 successively.Friction lining 20,23 and main shaft 12 are for spline is connected, and ratchet 21 also is provided with diameter clearance with spindle set.Ratchet 21 and ratchet 24 couplings, ratchet 24 is contained on the fixed mounting base 15 by ratchet bolt 26.The both sides of ratchet 24 are provided with ratchet pad 22,25.Be provided with bearing 18 between described right supporting 19 and the fixed mounting base 15, be provided with bearing 14 between fixed mounting base 15 and the main shaft 12.The termination of cable wire 1 is fixed on reel 4 side end faces by cable wire fix screw 7, cable wire pressing plate 8.Be provided with an opening on overcoat 3, be provided with cable wire guide wheel 2 herein, cable wire 1 stretches out along cable wire guide wheel 2.Left end at main shaft 12 can be connected to slewing arrangement, and drive shaft is rotated, and also can take over the moving device 28 of rocking-turn.It is main shaft 12 and reel 4 disalignments that this device also can adopt eccentric structure, removes transition gear 6, and miniature gears 16 and inner gear 5 are directly mated.
Its working process is as follows: when hand wheel word 28 (or using motor-driven), main shaft 12 clockwise directions rotate (referring to direction shown in the arrow among the figure), because miniature gears 16 is connected with spindle thread, then miniature gears 16 moves to the left, while pressing friction sheet 20,23 and ratchet 21, together rotate by spline spindle 12 and friction lining 20,23, ratchet 21, ratchet 21, ratchet 24 are in slipping state.At this moment miniature gears 16 drives inner gear 5 and reel 4 rotations by transition gear 6, and cable wire 1 is wrapped on the reel 4, and the goods that hangs on cable wire 1 other end is mentioned.When need are suspended on when aerial, the main shaft 12 that stops operating gets final product self-locking, because after main shaft 12 stops, the gravity of goods leans on miniature gears 16 left sides by reel 4, inner gear 5, transition gear 6, friction lining 20,23, ratchet 21 are compressed, and ratchet 21 is stuck 24 this moments with ratchet, is in self-locking state.When the need goods descends, main shaft 12 is rotated round about, miniature gears 16 moves right.Unclamp friction lining 20,23 and ratchet 21, miniature gears 16, transition gear 6, inner gear 5 and reel 4 are all along counter-rotation at this moment, and goods begins to descend.
