Description

Technical Field

[0001] This utility model relates to the field of cold storage technology, specifically a lifting platform for cold storage trolleys to enter and exit. Background Technology

[0002] Cold storage receiving platforms are primarily used to manage the goods receiving process, ensuring goods are stored at optimal temperatures and optimizing resource allocation. Currently, cold storage receiving platforms, also known as material loading and unloading platforms, are mainly constructed of concrete, making them unsuitable for matching existing multi-level cold storage racks. Furthermore, they hinder direct access for transport vehicles to the cold storage, preventing long-distance direct transport. Utility Model Content

[0003] To address the aforementioned issues, the purpose of this utility model is to provide a cold storage trolley entry and exit lifting platform that can be matched with existing multi-layer cold storage shelves, facilitating direct entry of transport vehicles into the cold storage and enabling long-distance direct transport by transport vehicles.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a lifting platform for entering and exiting a cold storage trolley, comprising a rectangular suspension frame and a lifting device mounting frame horizontally disposed on one side of the top of the suspension frame. The suspension frame is provided with multiple pairs of symmetrical columns. The top of the suspension frame is fixed with upper and lower guide plates on the left and right sides respectively. The cross-section of the upper and lower guide plates is U-shaped. The same end of the upper and lower guide plates extends above one end of the lifting device mounting frame. The other end of the upper guide plate is much longer than the lower guide plate. A horizontal trolley moving lifting plate is disposed inside the suspension frame. A chain fixed at one end of the trolley moving lifting plate is fixedly connected to the sliding frame via a guide pulley at that end of the upper guide plate and the main body of the upper guide plate. A chain fixed at the other end of the trolley moving lifting plate is fixedly connected to the sliding frame via a guide pulley at that end of the lower guide plate and the main body of the lower guide plate. The sliding frame slides along the direction of the upper and lower guide plates on the lifting device mounting frame through a telescopic device.

[0005] Furthermore, U-shaped guide plates are fixed to the left and right sides of the sliding frame, respectively, and are fitted onto the left and right rods of the lifting device mounting frame. Support pulleys that contact the rods of the lifting device mounting frame are fixed to the three sides of both ends of the U-shaped guide plates.

[0006] Furthermore, fixed clamps are fixed to both sides of the sliding frame and fixedly connected to the chains on each side, and support wheels supported on the sliding frame rods are fixed between the fixed clamps on each side.

[0007] Furthermore, the telescopic device is a hydraulic cylinder, and the fixed end of the hydraulic cylinder is fixed to the side of the lifting device mounting frame near the lower guide plate, while the telescopic end of the hydraulic cylinder is fixedly connected to one side of the sliding frame.

[0008] Furthermore, the outer edge of the trolley's moving lifting platform is equipped with multiple sliding pulleys that contact the columns, so that when the trolley's moving lifting platform is raised or lowered, the sliding pulleys slide up and down in close contact with the corresponding columns.

[0009] Furthermore, each chain is fixedly connected to a chain fixing block fixed to the outer edge of the trolley's moving lifting plate.

[0010] Furthermore, the trolley's moving lifting platform is equipped with upward-bent guardrails on both sides.

[0011] Furthermore, both ends of the suspension frame and the outer ends of the lifting device mounting frame are respectively fixed to the wall.

[0012] With the above settings, when the telescopic device pushes the sliding frame and pulls the chain to move, the four fixed points of the trolley lifting plate connected to the chain can be driven upward simultaneously, realizing the stable lifting of the trolley lifting plate. The descent is exactly the opposite. Therefore, it can ensure that the lifting force of each lifting part of the large trolley lifting plate is uniform, and the overall operation is more stable. This utility model can better match the existing multi-layer cold storage racks, making it convenient for transfer vehicles to directly enter the cold storage and realize long-distance direct transfer of transfer vehicles.

Detailed Implementation

[0015] like Figure 1-3As shown, a lifting platform for entering and exiting a cold storage trolley includes a rectangular suspension frame 1 and a lifting device mounting frame 2 horizontally positioned on one side of the top of the suspension frame 1. The suspension frame 1 has multiple pairs of symmetrical columns 3. Upper guide plates 4 and lower guide plates 5 are fixed to the top left and right sides of the suspension frame 1, respectively. Both the upper guide plates 4 and lower guide plates 5 have U-shaped cross-sections. The same end of the upper guide plates 4 and lower guide plates 5 extends above one end of the lifting device mounting frame 2, while the other end of the upper guide plate 4 is significantly longer than the lower guide plate 5. The frame 1 is equipped with a horizontal trolley lifting plate 6. One end of the trolley lifting plate 6 is fixedly connected to the sliding frame 8 via the guide pulley 7 at the upper guide plate 4 and the main body of the upper guide plate 4. The guide pulley 7 plays the role of changing direction. The other end of the trolley lifting plate 6 is fixedly connected to the sliding frame 8 via the guide pulley 7 at the lower guide plate 5 and the main body of the lower guide plate 5. The sliding frame 8 is driven by the telescopic device 9 to slide along the direction of the upper guide plate 4 and the lower guide plate 5 on the lifting device mounting frame 2.

[0016] In order to make the sliding frame 8 slide smoothly on the lifting device mounting frame 2, the left and right sides of the sliding frame 8 are respectively fixed with U-shaped guide plates 10 sleeved on the left and right rods of the lifting device mounting frame 2, and the two ends and three sides of the U-shaped guide plates 10 are respectively fixed with support pulleys 11 that contact the rods of the lifting device mounting frame 2.

[0017] To more securely fix the chain, fixing plates 12 are fixed to both sides of the sliding frame 8 and fixedly connected to the chain on each side. Support wheels 13, which are supported on the rod of the sliding frame 8, are fixed between the fixing plates 12 on each side.

[0018] Specifically: the telescopic device 9 is a hydraulic cylinder, and the fixed end of the hydraulic cylinder is fixed on the side of the lifting device mounting frame 2 near the lower guide plate 5. The telescopic end of the hydraulic cylinder is fixedly connected to one side of the sliding frame 8. The outer edge of the trolley moving lifting plate 6 is provided with multiple sliding pulleys 14 that contact the columns 3, so that when the trolley moving lifting plate 6 is raised and lowered, the sliding pulleys 14 slide up and down close to the corresponding columns 3. Each chain is fixedly connected to the chain fixing block 15 fixed on the outer edge of the trolley moving lifting plate 6. The two sides of the trolley moving lifting plate 6 are respectively provided with upwardly bent baffles 16 to prevent the transfer car and transfer trolley from sliding off the sides of the trolley moving lifting plate 6.

[0019] The working principle of this utility model is as follows: During installation, both ends of the suspension frame 1 and the outer end of the lifting device mounting frame 2 are respectively fixed to the wall 17. Of course, the fixing and installation can also be carried out according to the shape and structural characteristics of the cold storage. Figure 3The dotted lines represent the two chains passing through the lower guide plate 5, and the two solid lines above the dotted lines represent the two chains passing through the upper guide plate 4. When the telescopic device 9 pushes the sliding frame 8 and pulls the four chains to move, it can simultaneously drive the four fixed points of the trolley moving lifting plate 6 to move upward, thus achieving a stable lifting of the trolley moving lifting plate 6. The descent is exactly the opposite, so it can ensure that the lifting force of each part of the larger trolley moving lifting plate 6 is uniform, and the overall operation is more stable. The transfer vehicle carrying the goods can move on the trolley lifting platform 6, and enter the upper or lower space of the cold storage from the outside of the cold storage, making it convenient to load and unload the goods on the transfer vehicle directly through the transfer trolley.

[0020] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
