Description

Technical Field

[0001] This application relates to the technical field of auxiliary equipment for metal smelting, and in particular to a lifting structure for facilitating the movement of cylindrical sponge iron ingots. Background Art

[0002] In the modern metal smelting field, the metal raw materials are first purified through a preliminary smelting process, so that the metal raw materials form raw materials with higher purity and stronger performance. Then, large-scale smelting is carried out in the concentrated area of leading metal processing enterprises, which helps to reduce the generation of harmful gases in the concentrated area of metallurgical factories, reduce the input cost of energy equipment, and improve the metallurgical efficiency. In the existing steelmaking process, the primary processing factory will burn the metal raw materials to form cylindrical sponge iron ingots. The purity of this kind of sponge iron ingot reaches a relatively high level, and there is less waste residue in the subsequent smelting, and almost no or a relatively small amount of harmful gases such as sulfur are generated. In the production process of cylindrical sponge iron, after smelting, the sponge iron ingots still need to be transferred and then transported to the subsequent crushing workshop for crushing treatment. In the transfer process of the cylindrical sponge iron ingots, the existing usage methods mostly use ropes to tie and cooperate with overhead cranes for lifting. This operation method has low efficiency, and personnel need to operate on each iron ingot. Some workshops use hooks for lifting, but when producing, the number of sponge iron ingots is large, and the hooks need to be aligned one by one, and the connection operation speed does not increase much, and it is easy to occur entanglement and other phenomena, and the transfer and lifting speed is still slow, affecting the production efficiency. Therefore, it is necessary to improve the existing lifting structure of sponge iron ingots to solve these problems. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present application in detail with reference to the accompanying drawings.

[0022] To more clearly understand the technical solutions shown in the embodiments of the present application, first, the operation of the existing hoisting structure for cylindrical sponge iron ingots is introduced.

[0023] After the existing cylindrical sponge iron ingots are produced in the factory, they will be stacked and then hoisted to the crushing workshop or other transportation equipment in sequence. During the hoisting process, it is necessary to connect and fix the long cylindrical sponge iron. In the existing operation methods, manual bundling of steel cables is mostly used, or a single long rod is designed to cooperate with ropes for hoisting. During this hoisting process, it takes a long time for manual operation to connect the rope to the hook, consuming a large amount of time during the movement of a batch of sponge iron, which affects the production efficiency. Therefore, it is necessary to improve the existing hoisting structure of the cylindrical sponge iron to solve these problems.

[0024] Please refer to Figure 1 and Figure 2 , a hoisting structure for facilitating the movement of cylindrical sponge iron ingots disclosed in an embodiment of the present application, including: a boom body 1, a connecting sleeve 2, a chain 3, a collar 4, an extension strut 5, a limit card slot 6, a lifting lug 7, a reinforcing rib A 8, a reinforcing rib B 9, a connecting pin A 10, a connecting bar A 11, a fastening nut A 12, a connecting pin B 13, a connecting bar B 14, a fastening nut B 15, and an iron ingot body 24.

The connecting sleeve 2 is fixedly connected to the lower end of the boom body 1. The lower end of the chain 3 is movably connected to the connecting sleeve 2. The collar 4 is movably connected to the upper end of the chain 3. The limit card slots 6 are equidistantly opened on the surface of the extension strut 5. The cross-section of the extension strut 5 is rectangular. The lifting lug 7 is fixedly connected to the upper surface of the middle position of the extension strut 5. The reinforcing rib A 8 is fixedly connected to the inner surface of the middle position of the U shape of the boom body 1.

The connecting pin A 10 is fixedly connected to the surface of the middle position of the reinforcing rib A 8 facing the bent side of the U shape of the boom body 1. The through holes on the connecting bar A 11 are respectively connected in cooperation with the connecting pin A 10. The fastening nut A 12 is threadedly connected to the end of the connecting pin A 10 on the surface of the connecting bar A 11.

The provided collar 4 can respectively sleeve the chain 3 on the limit card slot 6 at the rear end of the extension strut 5. During actual use, the distance can be adjusted according to the specific diameter of the sponge iron ingot. The provided lifting lug 7 can be connected to the hook of the overhead crane, thereby realizing the overall hoisting of the extension strut 5. The provided reinforcing rib A8 can fix the bent part of the suspension rod body 1, so that its shape does not change when hoisting the ingot body 24, ensuring its own firmness, extending the service life, and improving the quality of the workpieces that can be hoisted. The provided reinforcing rib B9 can fix the upward bent position of the suspension rod body 1, ensuring the firmness strength. And the bent position of the suspension rod body 1 is located in the middle of the rod body, facilitating the centering of the center of gravity during the hoisting process, reducing the occurrence of tilting, and contributing to the improvement of safety. The provided connecting pin A10 can be connected to the connecting bar A11, and then the two are firmly connected through the fastening nut A12. The provided connecting pin B13 can form a connection with the connecting bar B14, and then is fixed through the fastening nut B15, realizing the support and fixation of the positions of adjacent suspension rod bodies 1. The provided connecting bar A11 and the connecting bar B14 cooperate with each other, which can effectively ensure that the suspension rod bodies 1 are parallel to each other, and the movement of rowed sponge iron ingots can be realized during the hoisting process, greatly improving the transfer efficiency compared with the manual transfer method.
