Problems solved by technology

[0002] The existing linear wedge rope locking device mainly includes wedges, balls, and rope lock housings. In order to make the wire rope and the rope lock self-locking and reduce the friction between the wedge and the rope lock housing, balls are added. But because the ball is in line contact with the wedge and the shell, the contact stress between them is relatively large, which greatly reduces the effective allowable load of the rope lock. At the same time, due to the damage of the ball or the deformation of the wedge, the wire rope may come out. Brings a lot of risk to the lifting system

Embodiment 1

[0035] The inclined wedge rope locking device is used for vertical shaft single rope hoisting, replacing the traditional wedge rope ring device, see below for details image 3 .

[0036] When the traditional shaft is single-lifted, the container and the wire rope are usually connected by a wedge-shaped rope ring device. Because when the wedge-shaped ring device is connected to the wire rope, the wire rope must be bent through the connecting device, so it is difficult to connect the wire rope. The larger the diameter of the wire rope, the less easy it is to operate, and the wire rope in the bending transition section is easy to be injured. And adopt oblique wedge locking rope device of the present invention, can effectively overcome above-mentioned defect.

Embodiment 2

[0038] The wedge rope locking device of the present invention can also be used in the wire rope automatic balance suspension device, replacing the traditional ball structure, and the connection is more reliable.

[0039] The invention provides a linear wedge rope locking device, which uses a material with a low friction coefficient instead of a conventional ball. At the same time, the sliding friction coefficient of this material is close to the original rolling friction coefficient, which can reach below 0.1, and can make the wire rope Reliably form self-locking with the rope lock, and at the same time greatly increase the effective load of the rope lock, avoiding the risk of the wire rope coming out of the rope lock due to damage to the ball or deformation of the wedge.

Abstract

The invention discloses a linear tapered wedge rope locking device. The device comprises a lifting steel wire rope, a rope locking device shell and wedge blocks, wherein the lifting steel wire rope penetrates through the rope locking device shell, the wedge blocks are wedged between the rope locking device shell and the lifting steel wire rope, a shell lining is arranged on the inner side of the rope locking device shell, and wedge block lining plates matched with the shell lining are arranged on the wedge blocks. According to the device, a low friction coefficient material is adopted to replace a conventional ball, and meanwhile, the sliding friction coefficient of the material is close to the original rolling friction coefficient and can reach 0.1 or below, so that the steel wire rope and the rope locking device reliably form self-locking, and meanwhile, the effective loading of the rope locking device is greatly improved, so that the risk that the steel wire rope is separated from the rope locking device due to the fact that the ball is damaged or wedges are deformed is avoided.

Description

technical field [0001] The invention relates to a linear oblique wedge rope locking device. Background technique [0002] The existing linear wedge rope locking device mainly includes wedges, balls, and rope lock housings. In order to make the wire rope and the rope lock self-locking and reduce the friction between the wedge and the rope lock housing, balls are added. But because the ball is in line contact with the wedge and the shell, the contact stress between them is relatively large, which greatly reduces the effective allowable load of the rope lock. At the same time, due to the damage of the ball or the deformation of the wedge, the wire rope may come out. It brings great risk to the lifting system. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a linear wedge rope locking device, which can reliably lock the steel wire rope and has high bearing capacity and reliability. [0004] In order t...
