The above is to perform a positioning operation on the opening of the lifting hook 203 when hanging an object inside the lifting hook 203.

[0032] Working principle: First, for the hook used on the hanging beam crane currently, there is a side hook steel plate 101 provided on the hanging beam body 1, and corresponding hooks are equipped on the side hook steel plate 101. The original design adopted a lifting ring connection and used a steel wire rope to directly connect and lift steel. Now, the connection method between the side hook steel plate 101 and the hook 203 is changed to a connection method combined with structures such as a side hook ear 2, a shackle 201, a lifting ring 202, and a hanging rod 204. The side hook ear 2 is selected from the same performance material as the original side hook steel plate 101, and the connection method is plugging and full welding. Among them, the shackle 201 is connected at the hook of the side hook ear 2. A connection design such as a hanging rod 204 and a shackle 201 is used between the side hook ear 2 and the hook 203. The lifting ring 202 and the hook 203 are of an integral structure design and are suspended on the hanging rod 204 through the lifting ring 202, which is a rotatable hook connection, avoiding the previous direct connection of the steel wire rope. The two ends of the hanging rod 204 are threadedly connected through a nut ring 205, and then welded at the rear connection point to ensure stability. After the transformation, the hanging form of the hanging beam ear avoids the serious wear of the steel wire rope by the original steel plate ear and the serious wear of the ear body itself, which has serious safety hazards. A rigid spacer 3 is added at the connection of the lifting ring 202. During use, if the spacer 3 wears out and fails beyond the standard, it can be replaced, which is convenient for maintenance, protects the structure of the side hook ear 2 body, and avoids the wear at the suspension position of the lifting ring 202, resulting in the problem of direct scrapping of the hook 203. Inspect, maintain, and scrap the hook to solve the safety hazards of the previous connection form and save the overall procurement cost of the hanging beam.

[0033] When the shackle 201 is hung on the side hook ear 2, at this time, a positioning rod 302 is installed at the inner end of the side hook ear 2, and the positioning rod 302 penetrates into the positioning groove 303 provided on the body of the shackle 201, so as to limit the connection point and improve the stability of the upper part when the hook is in use. When hoisting products in the hook 203, to ensure safety, an inner screw rod 308 is threadedly connected inside the inner screw groove 307, and the turning handle 309 is in a connected state with the inner screw rod 308. By rotating the turning handle 309, the threaded part of the inner screw rod 308 can be driven to move left and right inside the inner screw groove 307. When the pressing head 310 is abutted against the inner side wall of the hook 203, the pressing head 310 is made of rubber material, which can increase the friction force at the connection. The above is the positioning operation for the opening of the hook 203 when hoisting an object in the hook 203. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
