Description

Technical Field

[0001] This utility model relates to the technical field of lifting and transporting devices, and in particular to a lifting and transporting device for mobile shelving. Background Technology

[0002] Mobile shelving is a high-density storage system widely used in archives management, libraries, archives, museums, and warehouses to store large quantities of items such as documents, archives, books, and equipment. The basic components of mobile shelving are usually made of sturdy steel plates, providing stable storage space. When storing items inside the mobile shelving, a lifting device is required. The lifting device, through a drive system, moves the lifting platform up and down, thus allowing items to be moved to the storage location according to the height of the mobile shelving.

[0003] Lifting platforms are generally raised and lowered using hydraulic cylinders. Since the lifting platform is not reinforced, the lifting and lowering may be unstable. The area around the lifting platform for protecting objects is also small. Therefore, objects may fall from inside the lifting platform to the outside when it rises. Objects that are in contact with the surface of the lifting platform for a long time will be severely damaged. Therefore, it is particularly important to design a lifting and handling device for mobile shelving. Utility Model Content

Upon activation of the hydraulic cylinder, the lifting platform moves up and down. Items are placed on the surface of the wear-resistant layer, and the lifting platform transports them to the mobile shelving unit.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a lifting and transporting device for mobile shelving units:

[0022] Example 1:

[0023] like Figure 1-3 As shown, a lifting and transporting device for mobile shelving includes a transport vehicle body 1. A pressure-resistant base 2 is mounted on the top of the transport vehicle body 1. A hydraulic cylinder 3 is mounted on the top of the pressure-resistant base 2. The output shaft of the hydraulic cylinder 3 is connected to a lifting platform 4. Two reinforcing frames 6 are fixedly installed on the top of the pressure-resistant base 2. Each reinforcing frame 6 has a reinforcing rod 7 inside. A lifting block 8 is fitted onto one end of each reinforcing rod 7. Two extension plates 9 are mounted on one side of the lifting platform 4. An expansion plate 10 is installed between the inner walls of the two extension plates 9. A cover 14 is mounted on the top of the lifting platform 4. A pressure-resistant layer 15 is provided on the inner surface of the cover 14. The cooperation of the two lifting blocks 8 and the extension plates 9 supports one side of the lifting platform 4, enhancing the stability of the lifting platform 4 during lifting. After the cover 14 is installed with the lifting platform 4, it increases the height of protection for objects, preventing objects from falling from inside the lifting platform 4 to the outside during lifting. The pressure-resistant layer 15 is made of carbon fiber reinforced composite material, which has high compressive strength.

[0024] Example 2:

[0025] Based on Example 1, such as Figure 1 and Figure 4As shown, two limiting holes 16 are opened on one side of the cover 14, and two adjusting blocks 12 are provided on the top of the extension plate 10. One side of the extension plate 10 is in contact with one side of the lifting platform 4. The two extension plates 9 are positioned correspondingly. The wear-resistant layer 5 is made of high-chromium cast iron material, which has strong wear resistance and is suitable for environments that are subject to friction and impact for a long time, thus extending the service life of the lifting platform 4. After the bottom surface of the cover 14 is attached to the surface of the lifting platform 4, one end of the two limiting bolts 13 is embedded into the corresponding limiting holes 16.

[0026] Working Principle: Mobile shelving is a high-density storage system widely used in archives management, libraries, archives, museums, and warehouses to store large quantities of items such as documents, archives, books, and equipment. The basic components of mobile shelving are typically made of sturdy steel plates, providing stable storage space. A lifting device is used to store items inside the shelving. This device, driven by a drive system, moves the lifting platform 4 up and down, allowing items to be moved to their designated storage location according to the height of the shelving. The lifting platform 4 is generally raised and lowered using hydraulic cylinders 3. Since the lifting platform 4 lacks a reinforcing structure... This could lead to instability in the lifting platform 4, and the limited protection area around the lifting platform 4 for items. Therefore, items might fall from inside the lifting platform 4 to the outside during ascent, resulting in significant damage from prolonged contact with the surface of the lifting platform 4. Therefore, designing a lifting and transporting device for mobile shelving is crucial. After activating the hydraulic cylinder 3, the lifting platform 4 moves up and down. Items are placed on the surface of the wear-resistant layer 5, and the lifting platform 4 transports the items to the mobile shelving storage location. During lifting, the two extension plates 9 connect and drive the two lifting blocks 8 to the corresponding reinforcing rods 7. One end of the lifting platform 4 moves up and down. The two lifting blocks 8, in conjunction with the extension plate 9, can support one side of the lifting platform 4, enhancing the stability of the lifting platform 4 during lifting. The two extension plates 9 can support both sides of the extension plate 10. Triangles have stability, and the triangular plate 11 supports the extension plate 10 and the extension plate 9, enhancing the support strength on one side of the lifting platform 4. After the cover 14 is installed with the lifting platform 4, it increases the height of protection for objects, preventing objects from falling from the inside of the lifting platform 4 to the outside during lifting. The pressure-resistant layer 15 is made of carbon fiber reinforced composite material, which has high compressive strength and reduces... To enhance the impact strength between the object and the inner wall of the cover 14, the wear-resistant layer 5 is made of high-chromium cast iron, which has strong wear resistance and is suitable for environments subject to long-term friction and impact, thus extending the service life of the lifting platform 4. After the bottom surface of the cover 14 is attached to the surface of the lifting platform 4, one end of each of the two limiting bolts 13 is embedded into the corresponding limiting hole 16, and the two are threaded together, thereby limiting and installing the lifting platform 4 and the cover 14. Through this structure, the cover 14 of different heights can be disassembled and replaced. The cover 14 has multiple heights, and the appropriate cover 14 can be selected according to the height of the object.
