Double-round steel billet hanger

Abstract

The invention discloses a double-round steel billet hanger, belonging to the field of hangers for hanging steel billets in the metallurgic industry. The double-round steel billet hanger comprises a roller, a roller connection frame, a first hinge, an expansion device, a right upper arm, a right hinge, a right lower arm, a left lower arm, a left hinge and a left upper arm; the double-round steel billet hanger further comprises a middle caliper, a second hinge and a third hinge; the front end of the right lower arm is provided with a left caliper; the front end of the left lower arm is provided with a right caliper; circular arc grooves sunken to two edges are respectively arranged at the inner sides of the right caliper and the left caliper; the middle caliper is located at a crossed position of the right lower arm and the left lower arm; the middle caliper is heart-shaped; the third hinge and the second hinge are respectively located at the left side and the right side of the middle upper portion of the middle caliper; the middle section portion of the right lower arm is connected with the middle caliper through the third hinge; the middle section portion of the left lower arm is connected with the middle caliper through the second hinge. The double-round steel billet hanger can hang two round steel billets at the same time, so that the carrying efficiency is high; and the double-round steel billet has the advantages of convenience in use, high efficiency, reasonable design, easy manufacture and economy of materials.

Description

technical field [0001] The invention relates to the field of a hoisting tool for hoisting steel billets in the metallurgical industry, and more specifically relates to a double round steel billet hoisting tool which can be used for hoisting two round steel billets at one time. Background technique [0002] Metallurgical industry generally all adopts wire rope sling, electromagnet, C type hook and single round billet hanger when carrying out round billet hoisting operation at present. [0003] Steel wire rope slings are used in the case of round steel billet ≤ 80 ℃, and can be lifted by single or multiple ropes. It is necessary to rely on manual auxiliary operations. It is usually used for hoisting round billets in the storage area of ​​round billets. It is labor intensive and has many potential safety hazards. It is generally not used now. [0004] Electromagnetic discs are generally used when the temperature of the round billet is ≤600°C, and can be lifted by single or mul...

AI Technical Summary

Problems solved by technology

[0011] Aiming at the problem that the existing steel billet hoisting tool can only lift one steel billet at a time, the continuous casting machine produces a large number of high-temperature round steel per unit time, the existing lifting equipment has low efficiency and cannot meet the existing production needs, the present invention Provide a double-round steel billet spreader, which can lift two steel billets at a time, doubling the lifting efficiency
