Abstract

The invention belongs to the technical field of pulleys, and particularly relates to a multi-wire pulley device which comprises a pulley mechanism for a steel rope to bypass, pulley cantilevers for fixing the pulley mechanism and installing traction ropes, and a pin shaft for connecting the pulley mechanism with the pulley cantilevers. Under the condition of the same requirements on the pulley cantilevers, compared with a pulley cantilever on a traditional shackle type pulley, the pulley cantilevers in the shackle type pulley designed by the invention have the advantages that the arm distance is shorter; after long-time use, the increase degree of the face-to-face fit clearance between the pulley cantilevers and the pulley mechanism is small, then the probability that the clearance clamps the steel rope is relatively low, and the service life is long; and the pulley cantilevers are composed of two first cantilevers and two second cantilevers, when the two traction ropes need to be pulled in different directions, the two first cantilevers and the two second cantilevers are unfolded towards the two sides respectively to form traction points of the two pulley cantilevers in different directions, and the pulley cantilevers with the traction points in each direction are of a bilateral structure, so that the strength is high.

Description

[0001] Technical field

[0002] The invention belongs to the technical field of pulleys, in particular to a multi-wire pulley device. Background technique

[0003] At present, off-road vehicles often use winches, pulley shackles and other escape equipment in the off-road process. During use, winches and pulley shackles are used in combination. The use of winches can be divided into first-line, second-line and third-line methods.

[0004] The shackle pulley is composed of a pulley for the steel rope to bypass and a pulley cantilever with a traction rope connected by a pin shaft. The two pulley cantilever can be rotated and opened relative to each other; the steel wire rope is wound on the pulley, even if there is no opening. Rings can be wrapped around pulleys; however, there are three problems with traditional shackle pulleys:

[0005] 1. The shackle-type pulley cantilever will be deformed after a long time of pulling, so that the surface-to-surface fit gap between the pulley...
