Description

Technical Field

[0001] This utility model relates to the field of wire rope fixing technology, specifically a wire rope fixing device for lifting equipment. Background Technology

[0002] In the field of lifting operations, wire rope securing is a crucial step in ensuring the safe and stable operation of equipment. Currently, wire rope securing devices for lifting equipment mostly employ an integrated structure or a simple clamp assembly. While integrated securing devices are compact, they require significant manipulation of the wire rope during installation and disassembly, lack flexibility in adapting to different wire rope specifications, and suffer from high maintenance costs due to the difficulty in individually repairing or replacing internally worn components after long-term use, resulting in substantial maintenance costs.

[0003] Simple clamp combinations often rely on the clamping force of a single clamp for fixation. Under conditions of frequent vibration and large load changes during lifting operations, the clamps are prone to loosening, wire rope slippage, and even safety accidents. At the same time, the lack of a multi-directional limiting structure for fixing the wire rope makes it difficult to effectively limit the displacement of the wire rope in different directions, which cannot meet the requirements of stable fixing of wire rope in complex lifting operations and affects the safety and reliability of lifting operations. Therefore, a wire rope fixing device for lifting equipment is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wire rope fixing device for lifting equipment, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire rope fixing device for lifting equipment, comprising: The device includes a stop, a separate fixing component, and a U-shaped wire rope clamp, wherein the separate fixing component is disposed between the stop and the U-shaped wire rope clamp. The split-type fastener includes a second fastener and a third fastener. A limit plate is fixed to the outer side of the second fastener. A second limit groove is provided inside the third fastener on the side near the limit plate. A limit hook plate is fixed to the side of the third fastener away from the second limit groove. A first limit groove is provided inside the second fastener on the side near the limit hook plate. The upper ends of the second and third fixing members are both fitted with second bolts via threaded engagement, and the lower ends of the second bolts are rotatably fitted with second limiting blocks inside the second and third fixing members. By disassembling and assembling the modular fasteners, different diameter wire ropes can be flexibly adapted. During installation, the second and third fasteners are installed separately before the limiting structure is used, simplifying the installation process. The engagement of the limiting plate with the second limiting groove and the limiting hook plate with the first limiting groove, combined with the tightening of the second bolt and the second limiting block, restricts the displacement of the wire rope from multiple dimensions, greatly improving the stability of the fixation. This solves the problems of easy loosening and poor adaptability of traditional fixing methods, ensuring safe and efficient lifting operations.

[0006] Preferably, the limiting plate is adapted to the second limiting groove, the limiting hook plate is adapted to the first limiting groove, the limiting plate and the second limiting groove are fixed by screws, and the limiting hook plate and the first limiting groove are fixed by screws.

[0007] Preferably, positioning blocks are provided on both the front and rear sides of the second fixing member near the third fixing member, and the positioning blocks are fixedly connected to the second fixing member.

[0008] Preferably, the stop includes a first fixing member, the upper end of which is fitted with a first bolt via a threaded connection, and the lower end of the first bolt is rotatably fitted with a first limiting block inside the first fixing member.

[0009] Preferably, both end faces of the first fixing member are fitted with screws via threaded connections, and a stop bar is welded to the outside of the screws.

[0010] Preferably, a nut is mounted on the outside of the screw, and the nut is connected to the screw by a threaded connection.

[0011] Compared with the prior art, this utility model provides a wire rope fixing device for lifting equipment, which has the following beneficial effects: This utility model, by setting up a split fixing component, includes a second fixing component and a third fixing component. Utilizing the cooperation of a limiting plate with a second limiting groove, a limiting hook plate with a first limiting groove, and a second bolt driving the second limiting block to move, it achieves multi-directional and stable fixing of the wire rope. Installation and disassembly are convenient, and it is compatible with wire ropes of different specifications. The split structure facilitates quick alignment and fixing of the wire rope after bending, improving assembly efficiency. It solves the problems of inconvenient installation, unstable fixing, easy slippage, and poor adaptability of existing fixing devices, improving the safety and reliability of wire rope fixing during lifting operations and ensuring the stable operation of lifting equipment.
