An anti-sway device for a crane

Abstract

The invention discloses an anti-swing device for a crane, which comprises a slide rail assembly, a lifting slider, a cable assembly, a hook, a follow-up centering mechanism, a cable holding assembly and a locking mechanism; The middle part is provided with a wire hole for passing through several cables of the cable assembly, and the circular array of the connecting rod group is installed on the circumference of the fairlead, which includes the first connecting rod and the first connecting rod hinged between the fairlead and the lifting slider. The second connecting rod; the cable holding assembly is arranged in the fairlead, which includes a hard rubber ring and a soft rubber ring, the hard rubber ring is installed on the inner ring of the wire hole, and the soft rubber ring is installed on the hard rubber ring Inner ring, the inside of the soft rubber ring is symmetrically provided with electromagnets, and the soft rubber ring is pressed inward when the electromagnet is energized, so that the soft rubber ring clamps the cable in the middle; the locking mechanism is used to center the follower The locking of the initial state of the mechanism can reduce the shaking range of the crane cable and simplify the device.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an anti-sway device for a crane. Background technique [0002] When the crane is working, it needs to start and brake continuously. Because the wire rope has a flexible structure, it will sway, which is the main reason for the crane to sway. Affected by the working environment, when the crane is working outdoors, it will also sway the spreader due to the effect of wind. [0003] In order to reduce the shaking degree of the crane cable during use, some cranes will shorten the length of the steel wire cable to reduce the shaking of the cable. For some cranes that require lifting heavy objects to a specific height, in order to shorten the cable as much as possible However, for some heavy-duty cranes, the lifting and lowering of bulky lifting components not only consumes a lot of energy, but also poses safety hazards. Contents of the invention [0004] Therefore, the present inven...

[0003] In order to reduce the shaking degree of the crane cable during use, some cranes will shorten the length of the steel wire cable to reduce the shaking of the cable. For some cranes that require lifting heavy objects to a specific height, in order to shorten the cable as much as possible The length of use will consider the way the slide rail components and lifting sliders can be raised and lowered. However, for some heavy-duty cranes, lifting and lowering the bulky lifting components not only consumes a lot of energy, but also poses safety hazards.
