Abstract
The utility model relates to a friction type winch steel wire rope no-load reel off tension device, which comprises a driving shaft arranged on a rack, and a driven shaft, wherein a pair of symmetrically arranged cone friction wheels is fixed on the driving shaft; a wheel rim is sleeved outside the cone friction wheels; a first spring compression mechanism is connected between the two cone friction wheels; the driving shaft is connected with a transmission mechanism of a roller through transmission of a ratchet mechanism and a chain; a pressure roller matched with the driven shaft in a rolling way is sleeved on the driven shaft and is arranged corresponding to the wheel rim; a rope groove is correspondingly arranged in the centers of the outer surfaces of the pressure roller and the wheel rim; and one end of the driven shaft is hinged with the rack, and the other end of the driven shaft is provided with a second spring compression mechanism. When a rope is released, a ratchet wheel connected with a transmission mechanism of a winch drives the driving shaft to rotate through a pawl, the cone friction wheels on the driving shaft drives the wheel rim and the pressure roller to rotate synchronously, and the linear speed of the roller is smaller than the surface linear speed of the wheel rim, so that the steel wire rope is tensioned, the steel wire rope is prevented from being loosened on the roller, and normal rope release is ensured.
Description
Technical field
The utility model relates to a kind of winch steel wire rope stretching device, and the rope tightening device is put in the zero load of particularly a kind of friction-type winch steel rope.
Background technology
The friction-type winch is put when rope carrying out zero load, because steel rope lacks the pulling force of weight, rope stretching smoothly is prone to loose opening on reel, influences to put rope normally.
Summary of the invention
The technical matters that the utility model will solve provides a kind of friction-type winch steel rope zero load that can when zero load, put rope smoothly and puts the rope tightening device.
For solving the problems of the technologies described above; The technical scheme of the utility model is: the rope tightening device is put in the zero load of a kind of friction-type winch steel rope; Comprise frame, its innovative point is also to comprise: one is arranged on the imput shaft on the frame, is fixed with a pair of symmetrically arranged conical surface friction wheel on this imput shaft; The outer wheel rim that is set with of said 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 said imput shaft, said ratchet is connected with the transmission device of reel through chain gear, is fixed with the ratchet that inserts the ratchet teeth groove on the said 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 corresponding setting of said pinch roller with wheel rim; The outside face center correspondence of pinch roller and wheel rim is provided with grooving, and an end and the frame of said 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 advantage of the utility model is: when putting rope; Rotate by driving imput shaft through ratchet with winch transmission device bonded assembly ratchet; Conical surface friction on imput shaft wheel 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, thus tense wire rope; Avoid steel rope loose opening on reel, guarantee to put normally rope.
Description of drawings
Fig. 1 is put rope tensioning device structure scheme drawing for the zero load of the utility model friction-type winch steel rope.
Fig. 2 is along A-A line view among Fig. 1.
The specific embodiment
Like Fig. 1, shown in 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.
Above-mentioned frame 1 is provided with an imput shaft 2; Key is connected with a pair of symmetrically arranged conical surface friction wheel 6 on this imput shaft 2; Be set with the wheel rim 7 that is mated outside the conical surface friction wheel 6, the inner peripheral surface of wheel rim 7 is the conical surface, is connected with the first spring application mechanism between the two conical surface frictions wheel 6; This first spring application mechanism comprises bolt 81, nut 82, stage clip 83, and bolt 81 passes two conical surface frictions wheel, 6 back cover compression springs 83 and is threaded with nut 82.Jam nut 82 is tightened up two conical surface frictions wheel 6 by bolt 81, makes the outside face of conical surface friction wheel 6 be 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, and the other end is provided with the second spring application mechanism 11, and this 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, make pinch roller 10 be close to wheel rim 7 through spring application mechanism 11.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 through chain gear.And the linear velocity of reel is less than the linear resonance surface velocity of wheel rim 7.
Concrete principle of work is: when putting rope; Rotate by driving imput shaft 2 through ratchet 5 with winch transmission device bonded assembly ratchet 3; 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.
When receiving rope, unclamp nut 82, make two conical surface frictions take turns 6 outside faces and no longer be close to wheel rim 7 inside 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.
