Description

Technical Field

[0001] The utility model relates to the technical field of wire rope winding, in particular to a wire rope winding device for port hoisting machinery. Background Technique

[0002] Equipment is the guarantee of production. In particular, machinery such as portal cranes and ship unloaders are the most important hoisting equipment for coastal ship unloading and barge shipping in front of the wharf, and are the absolute "front line" of the company's production. There must be no sloppiness in their maintenance work. Ensuring the highest possible equipment integrity rate and improving the online utilization rate of equipment are the first requirements of equipment management; the replacement of the hoisting wire rope is the most important repair item in the overhaul of hoisting equipment. Ensuring the repair quality and shortening the repair time are particularly important. Its repair process is roughly divided into three steps: replacement of the old wire rope, casting of the new wire rope end (pear-shaped sleeve), cooling, and limit adjustment. Among these, the casting and cooling of the wire rope end (pear-shaped sleeve) are the most time-consuming. To ensure quality, the rope end must be cooled naturally. If the wire rope is damaged and needs to be replaced during the operation of the equipment, the existing repair process will inevitably cause the equipment to stop for a longer time, delaying the production progress; to improve the emergency handling ability of wire rope failures in hoisting equipment, reduce the impact of failure shutdown on production, and thus improve the online utilization rate of equipment, it is particularly necessary to manufacture a wire rope winding device to improve the wire rope replacement work.

[0003] The patent number is; CN 213623038 U discloses a wire rope winding device for port hoisting machinery. Through the mutual cooperation of a sliding rod, a first spring, a movable sleeve, a runner, a limiting strip and a limiting groove, when the driving motor and the reducer drive the winding roller to rotate to wind the cable, the cable is strained and tightened. Under the limiting action of the runner, the position of the cable itself remains fixed first. As the cable is continuously wound, the position of the cable displaces during the winding process. The cable drives the runner to displace during the movement, and the runner drives the movable sleeve to displace horizontally along the sliding rod during the movement. At the same time, the first spring deforms and stores energy under the push of the movable sleeve, thus avoiding the phenomenon that the traditional idler mechanism is difficult to limit the cable during use, and thus avoiding the phenomenon that the cable is easily worn significantly during the winding and unwinding process, and improving the service life of the cable. This device is not convenient for disassembling and replacing the winding shaft after winding, and relies on the first springs on both sides to push the cable to move to prevent the cable from being wound and limited during the winding process. However, the cable moves passively and the moving speed of the cable cannot be controlled, which may cause local cable accumulation on the winding shaft. Content of the Utility Model
