Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] Such as Figure 1 to Figure 6 As shown, a device for relieving wire rope stress in this embodiment includes a bracket 1 and a fixing device. The fixing device can be placed on the upper surface of the bracket 1 in a horizontally rotatable manner. The center hole 11, the fixing device can clamp and position the steel wire rope 7 passing through the center hole 11 of the bracket 1, and a rotating device that can clamp the steel wire rope 7 and enable the steel wire rope 7 to rotate horizontally is arranged above the fixing device ;
[0022] The bracket 1 is made of a steel plate with a thickness of not less than 3mm. The usual size of the steel plate is 300mm×400mm, and it can also be set according to the size and position of the reducer box platform of the crane. The length ≥ 50mm (the length is adjusted according to the size of the st...

A device capable of eliminating steel wire rope stress comprises a support (1) and a fixing device. The fixing device can be transversely rotatably arranged on the upper surface of the support (1), a central hole (11) for a steel wire rope (7) to penetrate is formed in the support (1), the steel wire rope (7) penetrating the central hole (11) of the support (1) can be clamped and positioned through the fixing device, and a rotating device capable of clamping the steel wire rope (7) and enabling the same to transversely rotate is arranged above the fixing device. The device has the advantages of simple and reasonable structure; by the arrangement of the fixing device and the support, the steel wire rope can rotate stably under the action of the rotating device, so that the steel wire rope stress can be conveniently eliminated, friction can be reduced, and hidden danger of accidents can be reduced; the device is light in weight, small in size, simple to operate, free of power and large working sites, labor and material resources are greatly saved, and production efficiency is improved; the device is widely applicable to occasions where stress of the steel wire ropes used for a crane, a bridge crane, a hoist and the like is needed to be eliminated.
Description
technical field [0001] The invention relates to the manufacturing technology of crane equipment, in particular to a device for relieving stress of steel wire ropes on the crane. Background technique [0002] Cranes are the main production equipment in shipyards, and wire ropes are a major component of crane hoisting. When a new crane is put into production or used, the new steel wire ropes are likely to be twisted and twisted together during production and use, which is very dangerous. The traditional way to eliminate the stress of the steel wire rope is: remove all the steel wire ropes, straighten the single strand of the steel wire rope, and turn it manually. The speed of stress relief is very slow. Complete stress relief cannot be ensured. Therefore need to design a kind of device that can easily eliminate the wire rope stress. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a stress-eliminating device for ...
