Description

Technical Field

[0001] This utility model relates to the field of pallet lift technology, specifically a pallet lift used in the rare earth metal production process. Background Technology

[0002] Rare earth metal electrolysis requires a complex process, in which the electrolyzed metal blocks need to be transferred to pallets for subsequent testing processes, and these pallets need to be moved between different floors. Pallet lifts are specialized mechanical devices used for the vertical transport of pallets carrying materials or finished products, playing a crucial role in improving logistics efficiency and ensuring production safety. Automated transport reduces manual handling, significantly improving logistics efficiency. In multi-story factories, lifts can avoid safety hazards such as falls and collisions that can occur with manual handling, and are especially suitable for transporting materials under heavy loads or high temperatures. Made of high-strength steel, they have a compact structure and small footprint, suitable for various factory layouts. Single-column, double-column, and four-column configurations are available to meet specific needs, or different work platforms can be configured. The drive system uses high-performance hydraulic transmission, adaptable to harsh environments such as high temperatures and heavy loads. Operation is simple and requires no specialized knowledge.

[0003] Chinese Patent Publication No. CN221235139U discloses a lithium battery tray lifting device, including a base. A lifting shell is fixedly mounted on the upper center of the base. A mounting seat is fixedly mounted on the lower center of the base. A support shaft is rotatably mounted on the upper end of the mounting seat. A rotating shaft is fixedly mounted on the upper center of the base. A lead screw is rotatably mounted on the center of the lifting shell. A rotating seat is fixedly mounted on the upper center of the lifting shell. The upper end of the lead screw extends into the rotating seat, and the lower end of the lead screw passes through the rotating shaft and is fixedly connected to the support shaft. This invention reduces worker contact during the lifting of lithium battery trays through automated lifting, thereby improving worker safety and preventing accidents caused by improper operation. Furthermore, the automated loading and unloading of lithium battery trays via a track further improves worker efficiency.

[0004] The existing technical solutions mentioned above have the following drawbacks: While automated loading and unloading of lithium battery pallets via tracks further improves the work efficiency of workers, if the steel cable breaks and the pallet lift suddenly falls during use, the lifting platform will fall from a height, causing damage to the pallet lift and the metal raw materials. Therefore, we propose a pallet lift for rare earth metal production processes to solve the problems mentioned above. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

[0028] Please see Figure 1-9 An embodiment of this utility model provides a pallet lift for rare earth metal production processes, comprising a track frame assembly 1, a large lifting platform assembly 2 slidably disposed on one side of the lower interior of the track frame assembly 1, a small lifting platform assembly 3 slidably disposed on one side of the lower interior of the track frame assembly 1, a bracket assembly 4 slidably installed inside the track frame assembly 1, a lifting transmission assembly 5 disposed between the lower part of the bracket assembly 4 and the lower end of the track frame assembly 1, a pallet positioning assembly 7 disposed inside one side of the large lifting platform assembly 2 and inside the small lifting platform assembly 3, a pallet 29 movably placed above the pallet positioning assembly 7, an emergency braking assembly 10 disposed inside the large lifting platform assembly 2 and the small lifting platform assembly 3, and an acceleration sensor 31 fixedly installed at the middle position of the lower end of the large lifting platform assembly 2 and the small lifting platform assembly 3.

[0029] When the wire rope 22 breaks, the acceleration sensor 31 senses and measures the acceleration change of the large lifting platform assembly 2 and the small lifting platform assembly 3 during the movement, and converts it into an electrical signal output. The corresponding emergency brake assembly screw 11 is activated according to the received signal.

The emergency braking component drive plate 12 is installed on one side above the emergency braking component screw 11 inside the small lifting platform component base 16. The emergency braking plate 13 is fixedly installed on one side of the emergency braking component drive plate 12. The emergency braking plate 13 is located on one side of the steel wire rope connecting component 14. The emergency braking component screw 11 is electrically connected to the acceleration sensor 31.

[0033] Please see Figure 9 The emergency brake plate 13 has three equidistant limiting block grooves 32 on one side near the track frame assembly 1. The limiting block grooves 32 are right-angled trapezoidal grooves, and the lower end of the limiting block grooves 32 is inclined towards the limiting block 19. The limiting block 19 is adapted to the limiting block grooves 32.

[0034] Please see Figure 1 , Figure 6 and Figure 7 The track frame assembly 1 has two opposing inner sides with bracket assembly roller grooves 21. The bracket assembly 4 is provided with a bracket assembly support frame 23. The upper and lower ends of the bracket assembly support frame 23 are symmetrically and rotatably mounted with bracket assembly rollers 24. The bracket assembly rollers 24 are slidably connected to the bracket assembly roller grooves 21. The lower part of the upper bracket assembly roller 24 is equipped with a limit wheel 26. The inner middle position of both sides of the bracket assembly 4 is rotatably mounted with wire rope rollers 25. The upper part of the wire rope connecting assembly 14 is fixedly connected with a wire rope 22. The wire rope 22 is wound around the outside of the wire rope roller 25 and the other end is fixedly connected to the middle position of the track frame assembly 1. The middle position of the lower end of the bracket assembly 4 is fixedly connected to the upper end of the lifting transmission assembly 5.

[0035] Please see Figure 3 , Figure 5 and Figure 8 The pallet positioning component 7 includes a pallet limiting frame 27 and a pallet limiting plate 28. The pallet limiting frame 27 is provided on the pallet positioning component 7. The pallet limiting frame 27 is fixedly connected to the base 6 of the large lifting platform component and the base 16 of the small lifting platform component respectively. The pallet limiting plate 28 is fixedly installed on the outside of the four corners of the pallet limiting frame 27. The pallet limiting plate 28 is a right-angle plate. The pallet support foot 30 is fixedly installed on the four corners of the lower end of the pallet 29. The lower end of the pallet support foot 30 is in contact with the pallet limiting plate 28. A metal billet 18 is placed on the top of the pallet 29.

[0036] Working principle: In use, the pallet 29 containing the metal billet 18 is placed above the pallet limiting plate 28. At this time, the pallet support feet 30 of the pallet 29 are located inside the pallet limiting plate 28 and are in contact with the pallet limiting plate 28, thereby limiting the pallet 29 and preventing the metal billet 18 from falling due to displacement caused by vibration when the pallet 29 moves upward. When the large lifting platform assembly 2 moves upward, the lifting transmission assemblies 5 on both sides of the large lifting platform assembly 2 are activated. The lifting transmission assemblies 5 are connected to the hydraulic station, and the hydraulic station and the lifting... The lifting transmission components 5 are connected by a sealed oil circuit equipped with a solenoid valve. Each lifting transmission component 5 is a multi-section hydraulic cylinder. The height of the lifting transmission component 5 can be adjusted by the hydraulic station. When the lifting transmission component 5 extends, it drives the bracket assembly 4 to move downwards under the limit of the track frame assembly 1. The wire rope 22 rolls on the wire rope roller 25, thereby pulling the large lifting platform assembly 2 upwards, thus lifting the large lifting platform assembly 2. When the lifting transmission component 5 retracts, the wire rope 22... The large lifting platform assembly 2 is pulled downwards. When the small lifting platform assembly 3 needs to be moved, the lifting transmission assembly 5 on one side of the small lifting platform assembly 3 can be adjusted to drive the small lifting platform assembly 3 to move up and down. Hydraulics is used as the lifting power, with a large load capacity. No upper hoisting point is required, no machine room or inspection is needed, and multi-point control of up and down is achieved. When the wire rope 22 breaks, the acceleration sensor 31 senses and measures the acceleration change of the large lifting platform assembly 2 and the small lifting platform assembly 3 during the movement, and converts it into an electrical signal output. The corresponding emergency brake assembly screw 11 is activated according to the received signal. The emergency brake assembly screw 11 drives the emergency brake assembly drive plate 12 to move away from the center of the large lifting platform assembly 2 and the small lifting platform assembly 3. The emergency brake assembly drive plate 12 pushes the emergency brake plate 13, so that the emergency brake plate 13 approaches the limit block 19 until the limit block 19 enters the interior of the limit block groove 32. Thus, the limit block groove 32 and the limit block 19 limit the descent of the large lifting platform assembly 2 and the small lifting platform assembly 3, thereby preventing them from falling.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
