Problems solved by technology

The result of slipping under heavy load is the severe wear of the protective skin of the cable and the load impact of the load-bearing components of the cable. Too frequent slipping can also generate friction and heat generation, which will cause the temperature of the cable skin to be too high, which will reduce the use of the cable. The actual use also shows that the sliding impact in the heavy load state is likely to cause damage to the cable skin

Embodiment Construction

[0013] Such as figure 1 , 2 , 3, the present invention includes a reel (1), a friction ring (2) and a pair of annular shoulders (3), an annular friction groove is opened on the reel (1), and the friction ring (2) is installed on the reel In the annular friction groove on (1), a pair of annular retaining shoulders (3) are respectively installed on both sides of the reel (1) through nuts.

[0014] The friction ring 2 consists of one or more friction rings.

[0015] The reel 1 and a pair of annular shoulders 3 are integrated.

[0016] How to use: Install at least one friction ring (2) on the end of the cable leaving the drum. If the winch is used for two-way traction (or retraction with load) of the cable, a friction ring (2) is provided at both ends of the drum. A friction ring (2) can be added at the end of the cable with less tension. Install shoulders (3) on the outside of the friction ring (2) to prevent the friction ring (2) from slipping out of the rigid reel (1) alo...

Abstract

The invention provides a rope winch winding drum for lifting off and retracting of an aerostat. The rope winch winding drum comprises a winding drum body (1), a friction ring (2) and a pair of annular stop shoulders (3). An annular friction groove is formed in the winding drum body (1). The friction ring (2) is installed in the annular friction groove in the winding drum body (1). The pair of annular stop shoulders (3) is installed on the two sides of the winding drum body (1) respectively through nuts. The rope winch winding drum for lifting off and retracting of the aerostat has the advantages that the rope winch winding drum is simple in structure and practical, the structural appearance of a conventional winding drum can be guaranteed, the traction performance of the conventional winding drum can be guaranteed, and installation, piece replacement and maintenance are convenient; the surface abrasion and load impact to a rope can be reduced in a large-load state, and the service life of the rope is prolonged.

Description

technical field [0001] The invention relates to aerostat lift-off recovery, in particular to a cable winch drum used for aerostat lift-off recovery. Background technique [0002] At present, a cable winch drum structure is a multi-rope groove drum cable traction winch mainly used for flexible friction transmission such as a cable retracting winch, a cable traction machine or a deep-sea survey winch. In the drum structure of a general cable traction winch, the rope groove and the drum used for flexible friction transmission are integrated, and the rope groove and the drum rotate as a rigid part as a whole, and the rotation speed of each rope groove of the drum is synchronous. of. If the cables in the rope grooves do not cause elastic sliding due to the elastic elongation and deformation produced when being pulled, the linear velocity of the cables in each groove will be consistent with the linear velocity of the rope groove (or reel). However, the actual situation is not ...
