Description

Technical Field

[0001] This utility model relates to the field of cable lifting technology, and in particular to a flat lifting hook for cable reels in the cable industry. Background Technology

[0002] In the wire and cable industry, the conventional method for lifting wire reels is vertical lifting. However, in actual production, some processes require horizontal lifting of the wire reels. Taking the conductor annealing process as an example, wire reels filled with copper and aluminum monofilaments must be laid flat before lifting. This is because placing the wire reels filled with monofilaments horizontally in the annealing furnace maximizes the utilization of the annealing furnace volume and improves production efficiency.

[0003] In the wire and cable production process, the existing method for horizontally lifting conductor reels involves first adjusting the reel to a horizontal position, then inserting a crossarm through the center hole of the reel. Under upward force, the crossarm forms a straight line and engages with the sides of the shaft hole, thus achieving horizontal lifting. This lifting method has serious safety hazards and operational defects. When the two ends of the crossarm engage the annealed reel, the crossarm can slide left and right in the middle of the reel, making it difficult to maintain balance. After lifting, the crossarm is difficult to remove smoothly from the reel. This poses safety risks and increases the time cost of lifting operations. Therefore, developing an efficient and safe hook for horizontally lifting conductor reels is of great significance. Utility Model Content

[0004] This utility model provides a flat lifting hook for cable reels in the cable industry. It has a stable structure and is easy to operate, enabling safe and secure flat lifting of the reels, improving loading efficiency, filling the gap in existing technology, and providing a reliable guarantee for efficient and safe production in the wire and cable industry.

[0005] The technical implementation scheme of this utility model is as follows:

[0006] A flat hook for cable reels in the cable industry includes a crane lifting component, a connecting rope, a main hook, and a toggle mechanism. The upper part of the main hook is connected to the crane lifting component via the connecting rope. The main hook includes a left main hook body and a right main hook body, and a toggle mechanism is provided on the main hook. The toggle mechanism includes a connecting block, a connecting shaft, a positioning toggle block, and a rotating rod. One end of the connecting block is fixedly mounted on the left main hook body, and the other end of the connecting block is connected to the positioning toggle block via the connecting shaft. One end of the connecting shaft is connected to the rotating rod via a connector. A pre-tightening mechanism is provided between the left and right main hook bodies. A first bent hook and a second bent hook are respectively provided at the bottom of the left and right main hook bodies.

[0007] Optionally, the pre-tightening mechanism includes a return spring, and the two ends of the return spring are respectively connected to the left main hook body and the right main hook body side via a first connector and a second connector.

[0008] Optionally, the left main hook and the right main hook are connected to two spool pin holes on the spool via a first hook and a second hook, respectively.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0023] like Figures 1-5 As shown, a flat hook for cable reels in the cable industry includes a crane lifting component 401, a connecting rope 402, a main hook, and a turning mechanism 5. The upper part of the main hook is connected to the crane lifting component 401 via the connecting rope 402. The main hook includes a left main hook body 404 and a right main hook body 403, and the turning mechanism 5 is provided on the main hook. The turning mechanism 5 includes a connecting block 501, a connecting shaft 502, a positioning turning block 504, and a rotating rod 503. One end of the connecting block 501 is fixedly mounted on the left main hook body 404, and the other end of the connecting block 501 is connected to the positioning and actuating block 504 through the connecting shaft 502. One end of the connecting shaft 502 is connected to the rotating rod 503 through the connector. A pre-tightening mechanism 6 is provided between the left main hook body 404 and the right main hook body 403. The bottom of the left main hook body 404 and the right main hook body 403 are respectively provided with a first hook 412 and a second hook.

[0024] It should be noted that the main hook includes a left main hook body 404 and a right main hook body 403. The main hook is made of high-strength spring steel, which has high load-bearing capacity and anti-deformation performance and can carry a full coil of conductor. A connecting lug is provided on the top of the main hook to reduce the risk of equipment damage due to impact. The lug is connected to the overhead crane component 401 by a flexible connection, which facilitates reliable connection with external lifting equipment.

[0025] It should be further explained that in actual operation, the length of the main hook must be adapted to the height of the annealing furnace to ensure that the hook can lift the wire reel into the effective space. In addition, a toggle mechanism 5 is set inside the opening of the main hook. This structure can be flexibly adjusted according to the size of the wire reel being lifted, which greatly enhances the safety of the lifting process.

[0026] It should be further noted that one end of the connecting block 501 is fixedly arranged on the left main hook body 404, and the other end of the connecting block 501 is connected to the positioning toggle block 504 via a connecting rotating shaft 502. The positioning toggle block 504 is of an oval structure, and its side edge is attached to and connected with the right main hook body 403. Therefore, when the connecting rotating shaft 502 rotates, the entire positioning toggle block 504 can also rotate at the same time, thereby opening and closing the left main hook body 404 and the right main hook body 403. In actual use, the left main hook body 404 and the right main hook body 403 can be opened only by rotating the positioning toggle block 504, and the rotation adjustment distance of the positioning toggle block 504 is exactly adapted to the two reel pin holes 408 on the wire reel 409, which facilitates subsequent hoisting; after use, the positioning toggle block 504 only needs to be adjusted back to its position, and reset with the elastic stress generated by the pre-tightening mechanism 6. This manner facilitates the hook scraping portion of the main hook to pass through the reel central hole 411, facilitating subsequent operations.

[0027] As Figures 1-4 shown, the pre-tightening mechanism 6 comprises a return spring 601, and two ends of the return spring 601 are respectively connected to the side portions of the left main hook body 404 and the right main hook body 403 via a first connecting member 602 and a second connecting member 603 respectively; the left main hook body 404 and the right main hook body 403 are respectively connected to the two reel pin holes 408 on the wire reel 409 through a first hook 412 and a second hook.

[0028] It should be noted that the return spring 601 is installed at a suitable position of the main hook for resetting the hook. After an operator places the wire reel 409 at a predetermined position, the operator operates the hook to move downward to disengage the hook from the reel pin holes, and at this time the pulling force of the return spring 601 enables the hook to automatically close and reset, and be smoothly taken out from the reel central hole 411. The operation is convenient, which greatly improves the working efficiency and optimizes the hoisting process.

[0029] As Figures 1-5 shown, a positioning mark 407 is arranged at the upper part of the main hook; a reel central hole 411 is arranged on the wire reel 409, and a conductor 410 is arranged on a side portion of the wire reel 409; the connecting soft rope 402 is a steel wire rope.

[0030] It should be noted that one side of the bottom of the main hook is bent to form an "L"-shaped structure, and the spacing between the two hooks and the two reel pin holes 408 is positioned by a positioning slider 405. The reserved length at the tail end of the hook 412 is correspondingly increased according to the thickness of the reel pin holes 408, so as to ensure safe hoisting.

[0031] It should be further explained that, firstly, the opening degree of the opening and closing mechanism is adjusted according to the size of the reel 409 to ensure a precise fit between the hook and the reel; then, the device is reliably connected to the overhead crane hook or other lifting equipment, and the reel 409 is smoothly lifted off the annealing furnace with the power of the lifting equipment; during the lifting process, the positioning slider 504 is locked by the positioning locking handle 503 to firmly fix the reel and prevent it from falling off during lifting; after the lifting is completed, the locking state of the positioning slider 504 is manually unlocked, at which time the return spring 601 automatically resets, driving the bottom of the main hook to reset, so that the main hook and the reel 409 are smoothly separated, and the entire lifting operation is finally completed.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
