Abstract
The invention relates to a friction type winch steel wire rope no-load loosening and tensioning device. The device comprises a driving shaft arranged on a rack and a driven shaft, wherein a pair of symmetrical conical surface friction wheels are fixed on the driving shaft, rims are sleeved on the outsides of the two conical surface friction wheels, and a first spring pressing mechanism is connected between the two conical surface friction wheels; the driving shaft is connected with a transmission mechanism of a drum through a ratchet mechanism and chain transmission; and a pressing wheel is sleeved on the driven shaft, the pressing wheel is matched with the driven shaft in a rolling manner, the pressing wheel and each rim are arranged correspondingly, the centers of the outer surfaces of the two parts are provided with rope slots correspondingly, one end of the driven shaft is hinged with the rack, and the other end is provided with a second spring pressing mechanism. When the rope is loosened, a ratchet connected with a transmission mechanism of the winch is used to drive the driving shaft to rotate through a pawl and the conical surface friction wheels on the driving shaft drive the rims and the pressing wheel to rotate simultaneously; and as the linear velocity of the drum is lower than the surface linear velocity of the rims, the steel wire rope is tensioned, the loosening of the steel wire rope on the drum can be avoided and the normal loosening can be ensured.
Description
Technical field
The present invention relates to a kind of steel wire rope of windlass tightening device, particularly a kind of friction type winch steel wire rope no-load reel off tension device.
Background technology
Friction type winch is when carrying out the no-load loosening rope, because steel rope lacks the pulling force of weight, and smoothly rope stretching, easily loose opening on reel affects and puts normally rope.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of friction type winch steel wire rope no-load reel off tension device that can put smoothly rope when zero load.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of friction type winch steel wire rope no-load reel off tension device, comprise frame, its innovative point is also to comprise: one is arranged on the imput shaft on the frame, be fixed with a pair of symmetrically arranged conical surface friction wheel on this imput shaft, the outer wheel rim that is set with of described two conical surface frictions wheel is connected with the first spring application mechanism that the conical surface friction wheel outer surface is pressed on the wheel rim inner peripheral surface between the two conical surface frictions wheel; Be set with the ratchet that cooperates with its rolling on the described imput shaft, described ratchet is connected with the transmission device of reel by chain gear, is fixed with the ratchet that inserts the ratchet teeth groove on the described imput shaft.One is located at the driven shaft of imput shaft one side, the pinch roller that suit cooperates with its rolling on this driven shaft, the setting corresponding to wheel rim of described pinch roller, the outside face center correspondence of pinch roller and wheel rim is provided with grooving, one end and the frame of described driven shaft are hinged, and the other end is provided with the second spring application mechanism of pinch roller being close to wheel rim.
The invention has the advantages that: when putting rope, driving imput shaft by the ratchet that is connected with winch transmission mechanism by ratchet rotates, conical surface friction wheel on the imput shaft drives wheel rim and pinch roller rotates synchronously, because the linear velocity of reel is less than the linear resonance surface velocity of wheel rim, thereby tense wire rope, avoid steel rope loose opening on reel, guarantee to put normally rope.
Description of drawings
Fig. 1 is friction type winch steel wire rope no-load reel off tension device structural representation of the present invention.
Fig. 2 is along A-A line view among Fig. 1.
The specific embodiment
As shown in Figure 1, 2, comprise frame 1, imput shaft 2, ratchet 3, crowfoot 4, ratchet 5, conical surface friction wheel 6, wheel rim 7, driven shaft 9, pinch roller 10, the second spring application mechanism 11.
Be provided with an imput shaft 2 on the above-mentioned frame 1, key is connected with a pair of symmetrically arranged conical surface friction wheel 6 on this imput shaft 2, the conical surface friction wheel 6 outer wheel rims 7 that are mated that are set with, the inner peripheral surface of wheel rim 7 is the conical surface, be connected with the first spring application mechanism between the two conical surface frictions wheel 6, this the first spring application mechanism comprises bolt 81, nut 82, stage clip 83, and bolt 81 passes two conical surface frictions and takes turns 6 rear cover compression springs 83 and be threaded with nut 82.Jam nut 82 is tightened up two conical surface frictions wheel 6 by bolt 81, so that the outside face of conical surface friction wheel 6 is close to wheel rim 7.
One side of imput shaft 2 is provided with and the approximately parallel driven shaft 9 of its axis, the pinch roller 10 that suit cooperates with its rolling on this driven shaft 7, one end and the frame of driven shaft 7 are hinged, the other end is provided with the second spring application mechanism 11, this the second spring application mechanism 11 is basic identical with the first spring application mechanism structure that above-mentioned conical surface friction is taken turns setting on 6, here repeat no more, by spring application mechanism 11 so that pinch roller 10 is close to wheel rim 7.The outside face center of pinch roller 10 and wheel rim 7 all has the circular arc grooving, and the steel rope of winch passes between this grooving.
Be set with the ratchet 3 that cooperates with its rolling on the imput shaft 2, key is connected with crowfoot 4 on the imput shaft 2 of these ratchet 3 inner end surface sides, the a pair of ratchet 5 that cooperates with ratchet 3 is installed on the crowfoot 4, and ratchet 3 outer faces are provided with chain sprocket structure, and chain sprocket structure is connected with the transmission device of reel by chain gear.And the linear velocity of reel is less than the linear resonance surface velocity of wheel rim 7.
The specific works principle is: when putting rope, driving imput shaft 2 by the ratchet 3 that is connected with winch transmission mechanism by ratchet 5 rotates, conical surface friction wheel 6 on the imput shaft 2 drives wheel rim 7 and pinch roller 10 rotates synchronously, thereby tense wire rope is avoided steel rope loose opening on reel.
During rope closing, unclamp nut 82, no longer be close to wheel rim 7 inside faces so that two conical surface frictions are taken turns 6 outside faces, when rope belt driving wheel circle 7 and pinch roller 10 rotated, conical surface friction wheel 6 and imput shaft 2 were not rotated.
