Abstract
The utility model discloses a tensioning mechanism for laying of a traction steel cable of a winch. The tensioning mechanism comprises an end positioning bearing and a middle positioning bearing, wherein the end positioning bearing and the middle positioning bearing are arranged on a rotating shaft alternately. The position, at the upper end of the middle positioning bearing, of the rotating shaft is connected with a driving pulley through a flat key, the position, close to the end positioning bearing, of the rotating shaft is fixedly sleeved with a one-way bearing with an inverted T-shaped outer lining, the inverted T-shaped outer lining is sleeved with a driving gear with an upper friction sheet and a lower friction sheet, a pressing plate pressed on the upper friction sheet is integrally connected with the inverted T-shaped outer lining through a dowel, and a spring pressing sheet is arranged on the pressing plate. The position, close to the driving pulley, of a sliding chute is provided with a positioning driven pulley. A check ring is arranged in a groove formed in the inverted T-shaped outer lining above the pressing plate, and the spring pressing sheet is clamped between the check ring and the pressing plate. The tensioning mechanism has the advantages that the structure is simple, the steel cable can be accurately laid on a winding drum in the take-up and pay-off processes, and the disorder situation can not occur.
Description
Technical field
The utility model relates to winch pull line and lays, and especially relates to a kind of winch pull line and lays and use tensioner mechanism.
Background technology
Winch cable wire need to be pulled out by laying mechanism in the time of work on reel, when withdrawal, also will cable wire is wound on reel successively by laying mechanism.When cable wire is not with load, when cable wire does not stress, be easy to make cable wire to lay confusion, the next normal pull-out of impact is used.
Summary of the invention
The purpose of this utility model is to provide a kind of cable wire also can not lay neat winch pull line with load and lays and use tensioner mechanism.
For achieving the above object, the utility model can be taked following technical proposals:
Winch pull line described in the utility model lays with tensioner mechanism, and it comprises the end location bearing and the middle part location bearing that are disposed on turning cylinder, on the turning cylinder of location bearing upper end, described middle part, is connected with driving pulley by flat key; On the turning cylinder near end location bearing, fixed cover is equipped with the unilateral bearing with inverted T-shaped external bushing, on described inverted T-shaped external bushing, be set with the driving gear with upper and lower friction lining, the pressing plate being pressed together on upper friction plate is connected as a single entity by pin and described inverted T-shaped external bushing, on described pressing plate, is provided with spring pressuring plate.
Chute place near described driving pulley is provided with location follow-up pulley.
In the groove of offering on the inverted T-shaped external bushing of described pressing plate top, be provided with back-up ring, described spring pressuring plate card is placed between described back-up ring and pressing plate.
The utility model has the advantage of simple in structurely, while having realized folding and unfolding, cable wire is accurately laid on reel, there will not be chaotic situation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, winch pull line described in the utility model lays with tensioner mechanism, comprise the end location bearing 2 and the middle part location bearing 3 that are disposed on turning cylinder 1, on the turning cylinder of middle part location bearing 3 upper ends, be connected with driving pulley 5 by flat key 4; On the turning cylinder 1 near end location bearing 2, fixed cover is equipped with the unilateral bearing 7 with inverted T-shaped external bushing 6, on inverted T-shaped external bushing 6, be set with the driving gear 10 with upper friction plate 8, lower friction lining 9, the pressing plate 11 being pressed together on upper friction plate 8 is connected as a single entity by pin 12 and inverted T-shaped external bushing 6, is provided with the spring pressuring plate 13 of exerting pressure to pressing plate 11 on pressing plate 11; For making it simple in structure, in the groove of offering on the inverted T-shaped external bushing 6 of pressing plate 11 tops, be provided with back-up ring 15, spring pressuring plate 13 cards are placed between back-up ring 15 and pressing plate 11; For guaranteeing that cable wire is not from slippage in friction lining, be provided with location follow-up pulley 14 near the chute place of driving pulley 5, the chute of the chute of driving pulley 5 and location follow-up pulley 14 forms the circular channel of an approximate sealing, can be from slippage in chute while having guaranteed cable wire folding and unfolding, location follow-up pulley 14 can be fixed on pulley yoke by bearing pin.
The circular channel of cable wire between driving pulley 5 and location follow-up pulley 14, pass.
When cable wire is transferred, motion is delivered on driving gear 10, under the effect of spring pressuring plate 13, pressing plate 11 compresses upper friction plate 8 and driving gear 10, rotatablely moves and is transferred on T shape external bushing 6 by pin 12, and T shape external bushing drives unilateral bearing 7 to rotate, and then drive turning cylinder 1 and driving pulley 5 to rotate, now require the tangential speed of driving pulley 5 chutes to be greater than the linear velocity of cable wire, and direction is consistent, provides tightening force to cable wire; .
When cable wire is packed up, be now delivered on driving gear 10 without motion, because unilateral bearing 7 only can unidirectional rotation, turning cylinder 1 can not rotate, and between cable wire and driving pulley 5, produces friction force, provides tightening force to cable wire.
