Abstract
A hand winch with automatic brake is composed of handle, small gear axle, ratchet wheel and friction plates between small gear and axle bush. The manual winch can rotate towards two directions, has an automatic braking function when rotating reversely, and can stay at any required position. Compared with the original manual winch, the function is greatly enhanced, the use is flexible and convenient, the structure is not very complicated, and the working reliability is high.
Description
The utility model relates to a kind of capstan winch, particularly hand winch.
Hand winch structure commonly used at present is all very simple, exactly by shaking handle, drive the steel rope of big gear wheel scrolling on it with miniature gears, and prevent reversing with pawl ratchet, in using this journey, can only therefore feel very inconvenient sometimes like this to a direction motion.
The purpose of this utility model provides a kind of self-stopping hand winch of being with.
The utility model adopts following technical scheme: be with self-stopping hand winch to comprise capstan winch seat, big gear wheel and axle, steel rope, miniature gears and parts such as axle, click and handle, its handle connects by the Acme thread nut with pinion shaft, this nut outer end also has a screw, ratchet and pinion shaft can relatively rotate, and a friction lining is respectively arranged between ratchet both sides and the miniature gears and between the bearing shell.When just changeing, working process is basic identical; When handle reverses, can form certain clearance between the miniature gears parts on shaft, under the weight effect, the end-face friction effect by two friction linings also utilizes the latching characteristics of Acme thread, realizes self-actuating brake.
Owing to adopt technique scheme, hand winch can be rotated to both direction, similar when just changeing to common capstan winch effect; So can stablize stop at an arbitrary position owing to have the self-actuating brake function during counter-rotating, just can just change as required or reverse when using like this, very flexible.The utility model original hand winch function is greatly strengthened, and structure is very not complicated yet, the functional reliability height by improving.
Be described further below in conjunction with drawings and Examples.
Fig. 1 is the utility model Facad structure scheme drawing.
Fig. 2 is the birds-eye view of Fig. 1.
In the illustrated embodiment, hand winch has designed the self-actuating brake structure.Working process is as follows: during the traction weight, clockwise rotate handle (1), drive Acme thread nut (6) along axially inwardly motion of pinion shaft (2), bearing shell (5), friction lining (3), ratchet (4), friction lining (3) and miniature gears (2) are compressed, form an integral body, similar to common capstan winch.Be rotated further handle, under the end-face friction effect, will drive pinion shaft (2) clockwise direction and rotate, thereby drive big gear wheel (7) and steel rope (8) rotation, to reach the purpose of traction weight.
When handle (1) anticlockwise motion, then drive Acme thread nut (6) along axially outwards motion of pinion shaft (2), at this moment can form certain clearance between the miniature gears parts on shaft, can rotate each other.Under the weight effect, steel rope (8) drives big gear wheel (7) clockwise direction and rotates, thereby drive pinion shaft (2) anticlockwise motion, make nut (6) inwardly move vertically again, again compress bearing shell (5), friction lining (3), ratchet (4), friction lining (3) and miniature gears (2), form an integral body, under the effect of ratchet stopping function, realize self-actuating brake.Continuous rotation handle (1), said process are realized repeatedly, just can regulate weight to desired location and stable the stop.
When not drawing weight, under the effect of the screw (9) of nut (6) outer end, handle and pinion shaft are joined together, when handle reversed like this, gapped between the miniature gears parts on shaft, ratchet was inoperative, can drive big gear wheel by miniature gears and rotate, loosen steel rope.
Claims (1)
1, a kind ofly is with self-stopping hand winch, comprise capstan winch seat, big gear wheel and axle, steel rope, miniature gears and parts such as axle, ratchet, ratchet and handle, it is characterized in that handle (1) connects by Acme thread nut (6) with pinion shaft (2), this nut outer end also has a screw (9); Ratchet (4) can relatively rotate with pinion shaft (2), and a friction lining (3) is respectively arranged between ratchet both sides and the miniature gears and between the bearing shell (5).
