Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting and hoisting technology, and in particular to a hoisting device for refined bismuth ingots. Background Technology
[0002] Bismuth ingots are metal products made by melting refined bismuth and casting it into a specific shape through a specific process. As a raw material with unique physical and chemical properties, bismuth ingots have a wide range of applications in electronics, metallurgy, medicine and other fields.
[0003] Currently, in the production process of refined bismuth ingots, after the bismuth ingots are melted and cast, they undergo cooling. The cooled bismuth ingots are then neatly stacked on a specific feeding plate according to a certain number. This stacking method not only helps with the sorting and counting of the bismuth ingots but also facilitates subsequent processing and transportation. When it is necessary to lift and move the refined bismuth ingots, usually only the feeding plate needs to be hoisted together with ropes. However, during the lifting process, due to various factors (such as vibration, wind, rope tension, etc.), the refined bismuth ingots may slide to the edge of the feeding plate, causing the overall center of gravity to shift, which in turn affects the stability of the lifting. This not only increases the risk during the lifting process but may also damage the ingots and lifting equipment.
[0004] Based on the above, this utility model proposes a lifting device for refined bismuth ingots with a limiting function. Utility Model Content
[0005] To overcome the drawback that refined bismuth ingots may slide to the edge of the unloading plate during lifting, causing the overall center of gravity to shift and affecting the stability of the lifting, which not only increases the risk during the lifting process but may also damage the ingot and lifting equipment, this utility model proposes a lifting device for refined bismuth ingots with a limiting function.

[0008] More preferably, it also includes a fixed plate, a second winding wheel, a transmission assembly, a pull rope, and a fourth motor. The fixed plate is fixedly attached to the upper front side of the mounting base. The left and right sides of the fixed plate are rotatably connected to the second winding wheel.

Detailed Implementation
[0023] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.
[0024] Example 1
[0025] A lifting device for refined bismuth ingots, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the system includes a base 1, a mounting base 2, a first motor 3, a first winding wheel 4, a second motor 5, a guide wheel frame 6, a rope 7, a feeding seat 8, a connecting hook 20, a mounting ring 21, a limiting plate 9, a rack 10, a fixed seat 11, a rotating shaft 12, a gear 13, and a third motor 14. The mounting base 2 is rotatably connected to the base 1. The first motor 3 is installed inside the base 1, and its upper output shaft is connected to the mounting base 2 via a coupling. The first winding wheel 4 is rotatably connected to the upper rear side of the mounting base 2. The second motor 5 is mounted on the upper rear side of the mounting base 2, and its left output shaft is connected to the first winding wheel 4 via a coupling. The guide wheel frame 6 is fixed to the upper front side of the mounting base 2. A rope 7 is wound on the first winding wheel 4, and the movable end of the rope 7 passes over the guide wheel frame 6 and through the upper front side of the mounting base 2. The hook 20 is fixed to the movable end of the rope 7. There are three mounting rings 21. One mounting ring 21 is placed on the hook 20 near the rope 7. The bottom of the mounting ring 21 is fixed to the feeding seat 8. The other two mounting rings 21 are fixed to the left and right sides of the top of the feeding seat 8, respectively. There are four limiting plates 9. The limiting plates 9 are slidably connected to the front, back, left and right sides of the bottom wall of the feeding seat 8. The bottom of each of the four limiting plates 9 is fixed to a rack 10. The bottom of the feeding seat 8 is fixed to a fixed seat 11. The rotating shaft 12 is rotatably connected to the middle of the fixed seat 11. The gear 13 is fixed to the upper side of the rotating shaft 12. The four racks 10 and the gear 13 are all meshed. The third motor 14 is installed on the lower side of the fixed seat 11. The output shaft on the upper side of the third motor 14 is connected to the rotating shaft 12 through a coupling. Rectangular sliding grooves are opened on the front, back, left and right sides of the bottom wall of the feeding seat 8.
[0026] like Figure 4 As shown, it also includes a protective shell 15, which is used for dust protection and load bearing and is fixed to the bottom of the material feeding seat 8.
[0027] Initially, the cooled bismuth ingots are neatly stacked in the feeding seat 8 in a certain number. When it is necessary to lift and move the bismuth ingots, the first motor 3 is controlled to drive the mounting seat 2 to rotate so that the connecting hook 20 on the rope 7 is directly above the feeding seat 8. Then, the second motor 5 is controlled to drive the first winding wheel 4 to rotate in the opposite direction. The first winding wheel 4 will release the rope 7. Under the weight of the rope 7 and the adjacent connecting hook 20, the rope 7 and the connecting hook 20 will move downward to the top of the feeding seat 8. The worker can take the connecting hook 20 to hook the mounting ring 21 in the middle of the upper side of the feeding seat 8. At the same time, the third motor 14 is controlled to drive the rotating shaft 12 to rotate in the opposite direction, thereby driving the gear 13 to rotate in the opposite direction. Since the rack 10 meshes with the gear 13, it will drive the limiting plate 9 to move inward and approach to contact the bismuth ingot. The limiting plate 9, which moves inward and approaches, will limit the front, back, left and right sides of the bismuth ingot in the feeding seat 8.
[0028] Following the steps outlined above, first control the second motor 5 to drive the first winding wheel 4 to rotate forward. The first winding wheel 4 will wind up the rope 7, thereby lifting the bismuth ingot block inside the unloading seat 8 through the connecting hook 20 and the mounting ring 21. Then, continue to control the first motor 3 to drive the mounting seat 2 to rotate, moving the unloading seat 8 directly above the destination. Next, control the second motor 5 to drive the first winding wheel 4 to rotate in the opposite direction, placing the unloading seat 8 on the destination. Finally, remove the connecting hook 20 from the mounting ring 21 to release the bismuth ingot. Once the lifting and handling are complete, the third motor 14 can be controlled to drive the rotating shaft 12 to rotate in the forward direction. This, in turn, drives the limiting plate 9 to move outward and separate from the bismuth ingot through the gear 13 and rack 10. The limiting plate 9 no longer limits the bismuth ingot block. In summary, by controlling the limiting plate 9 to limit the bismuth ingot around the feeding seat 8, the bismuth ingot is prevented from sliding to the edge on the feeding seat 8 due to various factors during the lifting and handling process. This prevents the overall center of gravity from shifting, improves the stability of the lifting, and reduces the risk during the lifting process.
[0029] Example 2
[0030] Based on Example 1, such as Figure 1 , Figure 7 and Figure 8As shown, it also includes a fixed plate 16, a second winding wheel 17, a transmission assembly 18, a pull rope 19, and a fourth motor 22. The fixed plate 16 is fixed to the upper front side of the mounting base 2. There are two second winding wheels 17, which are rotatably connected to the left and right sides of the fixed plate 16 respectively. The transmission assembly 18 is connected between the front sides of the two second winding wheels 17. The transmission assembly 18 consists of two pulleys and a flat belt. One pulley is fixed to the front side of the right second winding wheel 17, and the other pulley is fixed to the front side of the left second winding wheel 17. The flat belt is wound on the two pulleys. The pull rope 19 is wound on both second winding wheels 17. Two connecting hooks 20 are fixed to the movable ends of the two pull ropes 19 respectively. The mounting rings 21 on the left and right sides are placed on the adjacent connecting hooks 20 respectively. The fourth motor 22 is installed on the rear right side of the fixed plate 16. The output shaft of the front side of the fourth motor 22 is connected to the right second winding wheel 17 through a coupling.
[0031] When the first winding wheel 4 releases the rope 7, it simultaneously controls the fourth motor 22 to drive the right second winding wheel 17 to rotate in the opposite direction. This, in turn, drives the left second winding wheel 17 to rotate in both directions via the transmission assembly 18. Both the left and right second winding wheels 17 release the pull rope 19 together. The pull rope 19 then moves the adjacent connecting hook 20 downwards until it rests on top of the unloading seat 8. The worker can then use the connecting hook 20 to hook the adjacent mounting ring 21. Similarly, when the first winding wheel 4 rewinds the rope 7, it controls the fourth motor 22 to drive the right second winding wheel... When the second winding wheel 17 rotates in both directions, the second winding wheel 17 on both the left and right sides will simultaneously wind up the pull rope 19. According to the previous steps, when the material release seat 8 needs to be lowered after hoisting to the destination, the second winding wheel 17 will continue to release the pull rope 19 synchronously. In summary, by adding two force points to the material release seat 8 during the hoisting process through the second winding wheel 17, pull rope 19, connecting hook 20, and mounting ring 21, and ensuring synchronous winding and release, the stability of hoisting can be effectively increased. This not only improves the safety of hoisting operations, but also helps to protect the hoisting equipment and the hoisted items from damage.
