SU1364601A1 - Hand winch - Google Patents

Abstract

The invention relates to the field of lifting mechanisms, namely hand winches. The purpose of the invention is to increase reliability and ease of maintenance. To prevent the deflection 1 and the cargo 2 drums from slipping relative to the cargo rope 7 in the unloaded condition, the manual winch is equipped with spring-loaded clamping devices 10 and II, which are hinged to the hull I2. Spring-loaded clamping devices 10 and 11 are respectively adjustable stops 15 and I6. On the case I2, the suspension I4 is pivotally mounted, with a deflection drum 1, a gear wheel and a screw 13 mounted on it. Under the influence of the incoming branch 8 of the load rope 7 the stop 15 clamps the running branch 9 with a force that is directly proportional to the movement force, creating an additional clamp of the load rope 7. 2 Il.

The invention relates to the field of lifting mechanisms, namely to manual winches, intended for the mechanization of the movement of goods during the installation of technological equipment.

The aim of the invention is to increase the reliability and ease of maintenance.

Figure 1 schematically shows a manual winch, a general view; figure 2 - scheme of hoisting rope winch.

The hand winch includes two reels reeling the cargo rope - deflecting 1 and cargo 2 gears 3 and 4, mounted on axes 5 and 6 parallel to each other. The deflection drum 1 and cargo drum 2 are made with ring grooves in which In the form of the eight, a cargo rope 7 was laid with an incidental 8 and a descending 9 branches. To prevent the deflecting drum 1 and the cargo drum 2 from slipping relative to the cargo rope 7 in the unloaded condition, the manual winch is equipped with spring-loaded clamping devices 10 and 11,

and

Cargo 2 drums, rotates them. Due to the fact that the suspension 14 is hingedly connected to the housing 12, the oncoming branch 8, acting on the deflecting drum 1, deflects it towards the spring-loaded pressure device 10, which, resting against the adjustable stop 15, clamps the circumferential branch 9 with force is directly proportional to the displacement force, creating an additional clamp on the load rope 7. The deviation of the screw 13 does not affect the operability of the engagement, since this deviation occurs around the axis of the gear 3, i.e. all the engagement parameters are retained. Adjustable stop 15 allows for the necessary ratio of clamping force to load transfer force; the farther away from the deflecting drum 1 the adjustable stop 15, the more the deflection drum 1 deviates and the lower the clamping force, and vice versa.

If necessary, the branches of the load rope 7 can be swapped, for which the load is suspended on the escaping branch 9, which becomes

wound the cargo rope 7 from the entanglement branch and the branch 8 at the same time becomes a running branch, which makes it easier to maintain, since there is no need to rewind the rope when lifting the load without lowering it between two lifts.

The removable handle 17 is mounted on the opposite end of the screw 13, and the manual winch is suspended by the eyelet 19.

vanilla and pivotally connected to housing 12.

Between gears 3 and 4, a worm is mounted to 13, with the help of bearings rigidly fixed in suspension 14. Suspension 14 with deflection drum 1 installed on it, gear 3 and screw 13 are pivotally mounted in housing 12 on axis 6.

The spring-loaded clamping device 10, placed in the zone of the deflecting drum 1 on the housing 12, has an adjustable stop 15, and the spring-loaded clamping device 11, placed in the housing 12, has an adjustable stop 16. For rotation, the screw 13 is equipped with a removable the handle 17. On the body 12, the lugs 18 and 19 are installed, which coincide with the vertical axis of the cargo branch 8 and the vertical axis of the idle branch 9, respectively.

Manual winch works as follows.

The hand winch is suspended from the lugs 18. With the removable handle 17, the worm is rotated to 13, which is engaged with the gears 3 and 4 of the deflector 1
