Description

Technical Field

[0001] This utility model relates to the technical field of hook and cable auxiliary devices, and more specifically, to a hook and cable guide structure. Background Technology

[0002] In actual use, lifting hook cables are often affected by various improper operations, such as pulling at an angle or hoisting at an oblique angle. These abnormal operations can cause uneven wear between the wire rope and the hook device. Uneven wear not only shortens the service life of the wire rope but can also cause serious damage to the fixed pulley shaft, posing a safety hazard. Utility Model Content

[0003] The purpose of this invention is to provide a hook cable guide structure that solves the problem of uneven wear on existing hook cables.

[0004] This utility model is achieved through the following technical solution: a hook cable guide structure, including a hook assembly, a pulley rotatably connected inside the hook assembly, a bracket installed on the hook assembly, and a guide wheel rotatably connected on the bracket for contacting and guiding the cable, the axis of the guide wheel being perpendicular to the direction in which the cable enters the pulley.

[0005] Furthermore, the bracket is bolted with a limiting frame for limiting the steel cable.

[0006] Preferably, the bracket has a connecting hole for connecting the limiting frame, and the connecting hole is strip-shaped.

[0007] Furthermore, a rotating shaft is detachably connected to the bracket via a pin, and a guide wheel is movably sleeved on the rotating shaft.

[0008] Furthermore, the guide wheel is made of nylon rod.

[0009] This utility model has at least the following advantages and beneficial effects: by setting a guide wheel on one side of the hook assembly, the deviated steel cable can be effectively guided, so that the steel cable is wound into the roller from the angle of the same winding plane as the roller, avoiding the steel cable derailment or wear caused by asymmetrical force, increasing the stability of the system and reducing the operational risk.

[0013] The specific implementation method is described below with reference to the accompanying drawings.

[0014] Example

[0015] like Figure 1 , Figure 2 As shown, this embodiment mainly discloses a hook cable guide structure, including a hook assembly 1, a pulley 11 rotatably connected inside the hook assembly 1, a bracket 2 mounted on the hook assembly 1, and a guide wheel 3 rotatably connected to the bracket 2 for contacting and guiding the cable. The axis of the guide wheel 3 is perpendicular to the direction in which the cable enters the pulley 11. Specifically, the bracket 2 can be composed of two parallel steel plates. One end of the bracket 2 is welded to the cable entry end of the hook assembly 1, and the other end extends outward from the hook assembly 1 and is rotatably connected to the guide wheel 3. The edge of the guide wheel 3 is on the same plane as the winding surface of the pulley 11. At the same time, the axis of the guide wheel 3 is perpendicular to the direction in which the cable enters the pulley 11, which can effectively guide the deviated cable, so that the cable enters the pulley from the angle of the winding surface shared with the pulley, avoiding derailment or wear of the cable due to asymmetrical forces, increasing the stability of the device, and reducing operational risks.

[0016] Furthermore, in a specific implementation, a limiting frame 4 for limiting the steel cable is bolted to the bracket 2 provided in this embodiment of the present invention. Specifically, the limiting frame 4 is a semi-frame structure formed by bending steel bars, with its two ends connected to two steel plates of the bracket 2 respectively, and the middle part used to abut the steel cable, so that the steel cable is always effectively limited between the guide wheel 3 and the limiting frame 4, avoiding excessive stretching of the steel cable or derailment, improving safety, and reducing the risk of accidents caused by accidental operation.

[0017] Preferably, the bracket 2 has a connecting hole for connecting the limiting frame 4, and the connecting hole is strip-shaped. Specifically, the strip-shaped connecting hole can flexibly adjust the position of the limiting frame 4 to adjust the tightness of the limiting frame 4 against the steel cable, which is convenient for users to optimize and adjust according to different application scenarios, thus improving the applicability and adjustability of the equipment.

[0018] Furthermore, in a specific implementation, a rotating shaft 5 is detachably connected to the bracket 2 provided in this embodiment of the present invention via a pin, and a guide wheel 3 is movably sleeved on the rotating shaft 5. This facilitates the replacement or maintenance of the guide wheel 3, improving the maintenance efficiency of the equipment.

[0019] Furthermore, in specific implementations, the guide wheel 3 provided in this embodiment of the present invention is made of nylon rod. Nylon has good wear resistance and toughness, and compared to metal materials, it can reduce friction with the steel cable while extending its service life. In addition, nylon material is lightweight, which helps to reduce the burden on the overall structure and improves the overall maneuverability of the hook.
