Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, and more specifically, to a lifting device for round ferromolybdenum ingots used in ferromolybdenum smelting. Background Art

[0002] Ferromolybdenum smelting is a technical process of processing molybdenum-containing iron ore to extract valuable metals such as molybdenum and iron. This technical process has very important application value in fields such as steel manufacturing and aerospace industry. Ferromolybdenum is an alloy composed of molybdenum and iron. Round ferromolybdenum ingots refer to ferromolybdenum ingots with round cross-sections made by a specific casting process during or after ferromolybdenum smelting. This ingot is usually used for further processing and manufacturing. During the ferromolybdenum smelting and processing process, it is often necessary to handle heavy ferromolybdenum ingots, raw materials, equipment and tools. Lifting devices such as cranes and hoists can safely and efficiently transport these items from one place to another.

[0003] The existing structure uses claws for lifting when in use, which has the following disadvantages: 1. The angle of the claw is not easy to adjust properly, resulting in a fixed lifting position, while the iron ingot is usually uneven, which makes it difficult for the claw and the iron ingot to be stuck together, resulting in insufficient stability during lifting; 2. The claw is inconvenient to open and the lifting steps are cumbersome; 3. The lifting stability is poor. Utility Model Content

[0014] Optionally, the upper surface of the reinforcing support rod is horizontal, and the multiple reinforcing support rods are evenly stressed and have their stress directions downward, thereby avoiding force deviation and improving clamping stability.

[0015] Technical effects and advantages of the utility model:

[0016] By setting a limit assembly, the limit hook teeth can be limited by reinforcing the support rod and the limit hook teeth so that the limit hook teeth can rotate along the axis point where the limit hook teeth and the lower stop frame are connected, and each limit hook teeth and the reinforced support rod are easily spread toward the outside of the limit plate by extrusion, so that the support rod is stuck at the bottom of the workpiece;

[0017] The limit hook teeth and the reinforced support rod are driven downward by the elasticity of the spring, which makes it easy for the limit hook teeth and the reinforced support rod to hook on the workpiece. At the same time, the gravity of the workpiece itself is cooperated to avoid the spread of the limit hook teeth, so that the clamping is firm. The reinforced pull frame rotates along the axis point of the connection between the turntable and the limit plate, and then realizes the function of adjusting the hook position of the limit hook teeth and the reinforced support rod, ensuring the stability of the workpiece when lifting.

The reinforcing pull frame 2 rotates along the axis point of the connection between the turntable 10 and the limiting disk 1, and then the function of adjusting the hooking position of the limiting hook tooth 3 and the reinforcing support rod 4 is realized to ensure the stability of the workpiece when lifting. The specific structure of the assembly is arranged as follows;

[0027] The limiting assembly includes a reinforcing pull frame 2 arranged on the top of the limiting plate 1 for support, the bottom of the reinforcing pull frame 2 is rotatably connected with a plurality of angle-adjustable limiting hook teeth 3, and the bottom of the limiting hook teeth 3 is provided with a reinforcing support rod 4 for hooking the workpiece;
