Technical Field

[0001] This utility model relates to the field of elevators, specifically a new energy storage battery elevator. Background Technology

[0002] In recent years, with the rapid growth of global demand for clean energy, the new energy industry has ushered in unprecedented development opportunities. New energy storage batteries, as key equipment for energy storage and conversion, play a vital role in electric vehicles, renewable energy power generation (such as solar and wind power) storage systems, smart grids, and other fields.

[0003] The production process of new energy storage batteries involves multiple stages, including electrode preparation, cell assembly, battery module packaging, battery pack integration, and testing and aging. Each stage has specific process requirements and equipment configurations, and these stages need to be closely connected to form a complete production chain. In the battery production stage, vertical handling equipment, as the core equipment connecting various processes, directly affects production line efficiency and product consistency. Therefore, the lifting platform, as a key structure of vertical handling equipment, is a very important link in battery production. For example, the Chinese authorized patent with announcement number CN223150184U (a worm gear screw jack for easy positioning) includes a body, a cover bolted to the top of the body, a trapezoidal screw inside the body, a nut on the trapezoidal screw located inside the body, a driven worm gear mounted on the nut on the trapezoidal screw, a worm mounted inside the body via bearings, the worm gear meshing with the driven worm gear, a handwheel mounted on the input shaft end of the worm gear, and a controller mounted on the outside of the body.

[0004] Although the aforementioned existing technology has the function of driving and lifting the structure, the length of the lead screw is fixed and the lifting height is limited. If the lifting height is controlled by simply increasing the length of the lead screw, the height of the entire elevator will increase. Utility Model Content

[0022] 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1-5 One embodiment provided by this utility model:

[0024] (1) External equipment housing and related fixing structure

[0025] The outer equipment housing 1 includes an intermediate support tube 3. A lower mounting platform 2 is welded and fixed to the lower end of the intermediate support tube 3, and an upper protective cover 7 is welded and fixed to the upper end. An upper mounting platform 6 is welded and fixed to the lower exterior of the upper protective cover 7. A side protective cover 8 is welded and fixed to one side of the upper protective cover 7, and the side protective cover 8 communicates with the interior of the upper protective cover 7.

[0026] The lifting platform is installed at the four lower corners of the lifting platform. The lower mounting platform 2 is fixed to the lower support, and the upper mounting platform 6 is fixed to the upper support, forming an integrated support frame structure, which greatly enhances the stability of the vertical transport equipment during operation.

[0027] (2) Lower lifting box and related structures

[0028] A lower lifting box 13 is provided at the lower end of the middle support tube 3, and the lower lifting box 13 can move up and down along the middle support tube 3. A lower connecting ring 12 is provided at the center of the upper end of the lower lifting box 13, and an outer lifting screw 11 is rotatably connected to the lower connecting ring 12 through a bearing. The upper end of the outer lifting screw 11 extends upward to the upper end of the outer equipment housing 1.

[0029] Fixing plates 14 are welded and fixed to the two right-angled ends of the lower lifting box 13, and the fixing plates 14 are fixed to the moving platform.

[0030] The fixed plate 14 is fixed to the mobile platform; a set of drive components is provided on the mobile platform and the upper end of the upper bracket. The drive components include a motor, a drive shaft, a directional switch and other structures. The output shaft of the motor is connected to a directional switch. The output shaft of the directional switch extends to the left and right sides of the drive shaft. Both sides of the drive shaft are connected to directional switches. The output shaft of the directional switch extends to the front and rear ends of the drive shaft.

[0031] The drive shaft of the upper drive assembly of the mobile platform is connected to the second drive worm 15, which will be described later. Since the mobile platform can move up and down under the connection of the fixed plate 14, the drive assembly on the mobile platform always drives the second drive worm 15 to rotate. The drive shaft of the upper drive assembly of the upper bracket is connected to the first drive worm 9, which will be described later, providing a power basis for the rotation of the first drive worm 9.

[0032] Together, these components form a vertical transport system, enabling the lifting and transport of energy storage batteries.

[0033] (3) Related structures of the driving component

[0034] The first drive assembly and its related structures: A first drive worm gear 9 is installed inside the side protective cover 8, and its drive shaft passes through the side protective cover 8 and extends rearward. A first rotating worm wheel 10 is installed inside the upper protective cover 7. The first rotating worm wheel 10 is meshed with the first drive worm gear 9. An external lifting screw 11 passes through the first rotating worm wheel 10, and the external lifting screw 11 is threadedly connected to the first rotating worm wheel 10.

[0035] During operation, the drive assembly at the upper end of the upper bracket drives the first drive worm 9 to rotate. Since the first drive worm 9 and the first rotating worm wheel 10 are meshed, the first rotating worm wheel 10 is driven to rotate synchronously. Furthermore, due to the threaded connection between the first rotating worm wheel 10 and the outer lifting screw 11, the outer lifting screw 11 can move vertically upward.

[0036] This drive system utilizes the worm gear transmission principle, offering advantages such as a large transmission ratio, smooth transmission, and low noise. It precisely controls the speed and direction of the external lifting screw 11, enabling the initial lifting of the platform. The lifting process is smooth, reducing impact and vibration, and improving the equipment's operational accuracy and stability. This ensures the stability of the energy storage battery during operation, preventing large vibrations during lifting from affecting its quality.

[0037] The second drive assembly and its related structures: A second drive worm gear 15 is installed on one side inside the lower lifting box 13. A second rotating worm wheel 16 is rotatably connected in the middle of the lower lifting box 13. The second drive worm gear 15 and the second rotating worm wheel 16 are meshed together. The drive shaft of the second rotating worm wheel 16 passes through the lower lifting box 13 and extends rearward. The drive shaft of the upper drive assembly of the moving platform is connected to the second drive worm gear 15. The moving platform can move up and down under the connection of the fixed plate 14. Therefore, the drive assembly on the moving platform always drives the second drive worm gear 15 to rotate. When it needs to move upward again, the upper drive assembly of the moving platform works to drive the second drive worm gear 15 to rotate. Due to the meshing connection between the second drive worm gear 15 and the second rotating worm wheel 16, the second rotating worm wheel 16 is driven to rotate.

[0038] The outer lifting screw 11 has an internal thread 20 on its inner surface, and an intermediate rotating screw 19 is provided inside the outer lifting screw 11. The intermediate rotating screw 19 is threadedly connected to the internal thread 20 on the inner surface of the outer lifting screw 11. When the outer lifting screw 11 moves upward under the action of the first drive assembly, the lower lifting box 13 and the intermediate rotating screw 19 inside the outer lifting screw 11 move upward together.

[0039] The upper end of the second rotating worm gear 16 is fixed with an intermediate drive shaft 17, and a protruding key 18 is provided on the outside of the intermediate drive shaft 17. The intermediate drive shaft 17 and the protruding key 18 extend upward into the interior of the intermediate rotating lead screw 19. The interior of the intermediate rotating lead screw 19 is provided with an inner limiting groove 21 that matches the intermediate drive shaft 17 and the protruding key 18, and the intermediate rotating lead screw 19 slides along the intermediate drive shaft 17 and the protruding key 18. When the second drive assembly is working, the intermediate drive shaft 17 rotates. Since the intermediate drive shaft 17 and the intermediate rotating lead screw 19 are connected through the protruding key 18, the intermediate rotating lead screw 19 rotates together with the intermediate drive shaft 17. Since the intermediate rotating lead screw 19 is threadedly connected to the internal thread 20 on the inner surface of the outer lifting lead screw 11, the intermediate rotating lead screw 19 will continue to move upward along the interior of the outer lifting lead screw 11 under the action of rotation. This design, featuring internal and external lead screws combined with a central drive shaft and a protruding key, enables multi-stage lifting within a limited space, significantly increasing the lifting height of the elevator without increasing the overall height of the elevator itself.

[0040] (4) Slide structure

[0041] The outer surface of the intermediate support tube 3 is provided with a first sliding groove 4 along the lifting path of the fixed plate 14, and a second sliding groove 5 is provided along the lifting path of the second rotating worm gear 16.

[0042] The fixed plate 14 slides within the first slide groove 4 to connect with the mobile platform, thereby driving the mobile platform to move and providing precise guidance for the up-and-down movement of the lower lifting box 13.

[0043] The second slide 5 provides guidance for the lifting and lowering of the second rotating worm gear 16, further ensuring the motion coordination and stability of the entire internal structure of the elevator.

[0044] (5) Upper mounting structure

[0045] The upper end of the intermediate rotating lead screw 19 is fixed to the upper mounting part 22 by screws, and the upper mounting part 22 is fixed to the lifting platform by bolts. This connection method enables the intermediate rotating lead screw 19 to stably drive the lifting platform to move upward, and the connection is firm and reliable, capable of withstanding large loads.

[0046] Working principle: During the initial ascent, the upper drive assembly of the upper support rotates the first drive worm 9, which in turn rotates the first rotating worm wheel 10 synchronously. This causes the outer lifting screw 11 to move vertically upward. The lower lifting box 13 connected to the lower end of the outer lifting screw 11 and the intermediate rotating screw 19 inside the outer lifting screw 11 move upward together. The upper mounting piece 22 connected to the upper end of the intermediate rotating screw 19 is fixed to the lifting platform with bolts, thus driving the lifting platform to move upward.

[0047] When the platform moves upward again, the upper drive assembly of the mobile platform drives the second drive worm gear 15 to rotate, which in turn drives the second rotating worm wheel 16 and the intermediate drive shaft 17 connected to the second rotating worm wheel 16 to rotate together. Since the intermediate drive shaft 17 and the intermediate rotating lead screw 19 are connected by a protruding key 18, the intermediate rotating lead screw 19 rotates together with the intermediate drive shaft 17. Under the action of the rotation of the intermediate rotating lead screw 19, the intermediate rotating lead screw 19 will continue to move upward along the inside of the outer lifting lead screw 11. The upper mounting part 22 connected to the upper end of the intermediate rotating lead screw 19 is fixed to the lifting platform by bolts, driving the lifting platform to continue to move upward.

[0048] 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. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
