Description

Technical Field

[0001] The utility model relates to the technical field of rope guides, in particular to a rope guide for a wire rope hoist. Background Art

[0002] The hoist rope guide is composed of a rope guide nut, a rope guide plate, and a connecting steel belt. The rope guide plate moves horizontally toward both ends of the drum. When it reaches the limit position, it drives the limit rod installed on the drum shell to move together. When it reaches the limit position, it triggers the limit switch installed on the main motor to play a limiting role.

[0003] The rope guide is used for guiding the wire rope of the electric hoist when it is winding. The prior art discloses an improved structure of the rope guide of a wire rope electric hoist (authorization announcement number CN216190656U). This patented technology can save a pressure wheel seat and a pressure wheel compared with the prior art because it only uses one movable pressure wheel frame and one rope pressure wheel. The movable pressure wheel frame is tightened by the elastic force of the tension spring, which embodies the advantages of convenient and efficient disassembly and assembly of the movable pressure wheel frame; after the rope stop part and the arc-shaped inlet and outlet rope ring body are integrated into a structure, the fixed connection operation between the lower end of the rope stop part and the arc-shaped inlet and outlet rope ring body can be omitted.

[0004] Although this solution can achieve rapid installation and disassembly of the guide, in actual use, the guide still needs to be completely sheathed on the outside of the steel cable and the reel, which is inconvenient to install when the protective shell is set on the opposite side, thus affecting actual use.

[0005] Therefore, those skilled in the art provide a rope guide for a wire rope hoist to solve the problems raised in the above background technology. Utility Model Content
