Description

Technical Field

[0001] The utility model relates to the technical field of rope retaining devices, and particularly relates to a rope retaining device for a winch. Background Technique

[0002] A winch is a light and small lifting device that winds a steel wire rope or a chain around a drum to lift or tow heavy objects. It is also called a winch. Winches are roughly divided into three types: manual winches, electric winches, and hydraulic winches. Therefore, a rope retaining device for a winch is needed.

[0003] According to a rope retaining device for a winch disclosed on the patent network (the authorization announcement number is: CN 219409054 U), it is described that "the utility model discloses a rope retaining device for a winch, including: an upper rope retaining rod and a lower rope retaining rod installed on the winch frame, so that the steel wire rope on the winch extends out through the gap between the upper rope retaining rod and the lower rope retaining rod. A steel wire rope is wound around the drum of the winch. The rope retaining device further includes: an arc-shaped rope retaining rod, and the arc-shaped rod is arranged in the gap between the upper rope retaining rod and the lower rope retaining rod, so that the steel wire rope extends out through the gap between the upper rope retaining rod and the arc-shaped rod. By adding the arc-shaped rope retaining rod, the winch increases an upward emergence direction, improving the applicability of the winch. The uppermost rope retaining rod in the arc-shaped rope retaining rod exceeds the center line of the drum, and the lowermost rope retaining rod is located at the intersection of the drum and the plane of the chassis, which can effectively prevent the steel wire rope from slipping out of the drum when the rope exits upward from the side of the drum, meeting the safety requirements."

[0004] Regarding the above description, the applicant believes that there are the following problems: When the device is in use, adding the arc-shaped rope retaining rod increases an upward emergence direction for the winch, improving the applicability of the winch. The uppermost rope retaining rod in the arc-shaped rope retaining rod exceeds the center line of the drum, and the lowermost rope retaining rod is located at the intersection of the drum and the plane of the chassis, which can effectively prevent the steel wire rope from slipping out of the drum when the rope exits upward from the side of the drum, meeting the safety requirements. When the steel wire rope is wound around the drum of the winch, if it is not guided, the phenomenon of "rope chaos" may occur. Although the device can press the steel wire rope, it cannot guide the steel wire rope well, which may lead to the problem of "rope chaos" during rope winding. Content of the Utility Model

[0035]

[0035] In the actual operation process, when this device is used, the ratchet 216 outside the drum 214 is driven to rotate by the driving motor 213. Before that, the direction of the adjusting block 219 is adjusted so that the ratchet block 217 abuts against the adjusting block 219 under the restriction of the spring 218, thereby restricting the rotation direction of the drum 214. The gear rotating belt 225 outside the gear 223 is driven to rotate outside the rotating gear 224 by the motor 222, so that the gear rotating belt 225 drives the sliding plate 227 outside the rotating block 226 to slide on the top of the mounting plate 221. The steel wire rope passes through the inside of the auxiliary rotating roller plate 2210. By the sliding of the sliding plate 227 on the top of the mounting plate 221, when the steel wire rope is retracted and released, the phenomenon of "rope disorder" will not occur. The pushing spring 33 pushes the rope blocking rotating rod 32 inside the arc plate 31 to contact the steel wire rope outside the drum 214 and press it tightly.
