TECHNICAL FIELD
[0001] The utility model belongs to winch technical field especially relates to a winch rope dispenser deviation rectifying device. BACKGROUND
[0002] In the operation process of the winch, the rope is put and the rope is collected, which is two important links, which is directly related to the work efficiency and safety of the winch. The traditional winch system, especially in the case of using servo motor to drive the rope dispenser, faces a series of technical challenges. These challenges mainly reflect the speed coordination problem between the rope dispenser and the drum. Specifically:
[0003] Speed mismatching problem: during the process of putting and collecting the rope, if the speed of the rope dispenser is too fast or too slow relative to the speed of the drum, the angle of the steel wire rope winding on the drum will deviate. This deviation not only affects the neat arrangement of the steel wire rope on the drum, but also may cause the crossing, overlapping and even knotting of the steel wire rope, which seriously affects the normal working state of the winch.
[0004] Disordered arrangement of drum steel wire rope: the disordered arrangement of steel wire rope caused by speed mismatching will further aggravate the instability and safety hazard of the winch during operation. The disordered arrangement of steel wire rope may cause additional friction and resistance when the winch lifts or lowers heavy objects, reduce the work efficiency, and even cause equipment failure.
[0005] Shortened service life of steel wire rope: improper winding angle and arrangement mode will accelerate the wear and fatigue of steel wire rope. Steel wire rope working in bad conditions for a long time is more likely to have damage such as wire breakage and strand breakage, thereby greatly shortening its service life. This not only increases the maintenance cost, but also may cause safety accidents due to sudden breakage of steel wire rope.

Therefore, there is an urgent need for a new technical solution that can effectively control the speed of the rope dispenser and ensure its accurate matching with the speed of the drum, so as to maintain the neat arrangement of the steel wire rope and improve the work efficiency and safety of the winch.

[0030] Optimized description of the working principle of this utility model:
[0031] During the winch operation, when the wire rope of the drum is wound from right to left, the system implements an intelligent dynamic adjustment mechanism. Specifically, if the deviation correction roller (located on the right) is disengaged from the travel switch on the right, this action indicates that the current rope guide correction device is moving at a relatively fast speed and fails to keep pace with the winding speed of the wire rope. At this time, the travel switch on the right will respond quickly and send a signal to the drive motor control system to prompt it to reduce the speed. Subsequently, the movement speed of the rope guide box along the lead screw is reduced, effectively reducing the winding angle of the wire rope, thereby ensuring that the wire rope can be arranged neatly and orderly on the drum.
[0032] Conversely, when the correcting roller (located on the left) disengages from the left travel switch, this indicates that the rope guide's correcting device is moving too slowly and has not yet reached the ideal speed for wire rope winding. In this case, the left travel switch also immediately sends a signal, instructing the drive motor to increase its speed. This increases the speed of the correcting device along the optical bar, achieving the same goal of adjusting the wire rope winding angle and maintaining normal rope arrangement.
[0033] Through this ingenious design, the winch system can automatically adjust the movement speed of the rope-aligning and correcting device according to actual working conditions, ensuring that the arrangement of the wire rope on the drum always remains neat and orderly, thereby greatly improving the operating efficiency and safety of the winch.
[0034] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
