Description

Technical Field

[0001] The utility model relates to an auxiliary device for loading and unloading energy storage PACKs, and relates to the technical field of loading and unloading equipment. Background Technique

[0002] During the integration and boxing process of new energy storage PACKs, the energy storage PACKs are loaded and unloaded in the container by a forklift.

[0003] For the convenience and safety of loading and unloading, the existing PACK containers need to consider the height of the forklift fork tongue entering and the safe space. At least 2 cm of space is wasted for each layer of installation. For the bottom layer installed from top to bottom, the height even exceeds 2 cm. Calculated based on 8 PACKs in a cluster, adding 1 at the top and bottom respectively, 20 cm of space will be wasted. In addition, the previous installation method is prone to collisions, resulting in abnormal situations such as product dents and deformations, which tests the forklift operation skills of forklift operators. Therefore, an auxiliary device for loading and unloading energy storage PACKs is proposed, which not only facilitates the loading and unloading of energy storage PACKs, but also can optimize the installation space of the container and reduce costs. Content of the Utility Model

[0004] The purpose of the utility model is to provide an auxiliary device for loading and unloading energy storage PACKs in view of the defects or deficiencies in the prior art. By cooperating the electric push-pull mechanism arranged on the forklift with the push-pull bottom plate arranged at the PACK end, the quick installation and disassembly of the PACK can be conveniently realized, which not only improves the loading and unloading efficiency, but also can optimize the container space and enhance the loading and unloading safety.

[0024] See Figures 1-6As shown, the technical solution adopted in this specific embodiment is as follows: It includes an insertion mechanism 1 and a PACK fixing chassis 2. The insertion mechanism 1 is installed on a forklift 3, and the PACK fixing chassis 2 is located at the bottom of the PACK 4 and is detachably connected to the insertion mechanism 1. The insertion mechanism 1 includes a fixing rod 11, a linkage push rod 12, an electric telescopic rod 14, and a top rod 16. The fixing rod 11 is installed at the bent end of the fork tongue of the forklift 3. The motor end of the electric telescopic rod 14 is installed at the bottom of the fixing rod 11. The front end of the telescopic rod of the electric telescopic rod 14 is connected to the top rod 16. A stiffening rod 13 is provided on the inner side of the top rod 16 and connected to the bottom of the linkage push rod 12. In this embodiment, the traditional loading and unloading method of the PACK is changed. The traditional loading and unloading method is to directly lift the PACK to the corresponding position of the container by the forklift. The forklift moves in the PACK slot of the container to load and unload the PACK. At the same time, external pushing and pulling equipment is required for assistance. The requirements for external auxiliary equipment are high, and the container needs to have a large operating space, which is not conducive to space optimization and increasing storage capacity. Therefore, in This embodiment employs a two-part mold: an insertion mechanism and a PACK fixing chassis. The insertion mechanism is directly mounted on the forklift's forks, while the PACK fixing chassis is integrated into the bottom of the PACK. The insertion mechanism is an electrically operated push-pull structure. The fixing rod is first installed on the forklift's forks and serves as the main fixing structure. The electric telescopic rod is installed at the bottom of the fixing rod, with its front end connected to a top rod. The top rod is connected to a linkage push rod via a stiffening rod. When the electric telescopic rod is activated, the stiffening rod drives the linkage push rod, allowing for push-pull operations on the PACK after the linkage push rod connects to the PACK fixing chassis. This facilitates loading and unloading of the PACK. Furthermore, during loading and unloading, the forklifts do not need to fully enter the container; only the front end of the forklift needs to enter to connect the linkage push rod to the PACK fixing chassis for pushing and pulling. This is highly efficient and convenient, significantly reducing the forklift's operating space within the container, thereby effectively optimizing container storage space and improving space utilization.

[0025] More specifically, at least two stiffening rods 13 are symmetrically arranged. The end of the stiffening rod 13 away from the top rod 16 is provided with a connector 18 that connects to the bottom of the linkage push rod 12. In this embodiment, the stiffening rods can be selectively arranged according to different specifications of the PACK structure. At least two stiffening rods are provided and they are symmetrically arranged on both sides of the electric telescopic rod to ensure the balance of the pushing and pulling force and to ensure that the PACK can be pushed and pulled smoothly.

[0026] More specifically, several U-shaped fixing buckles 17 are symmetrically arranged on the side of the linkage push rod 12 facing the ejector rod 16. A fixing guide shaft 15 is arranged at the front end of the fixing buckle 17 and is slidably connected to the PACK fixed chassis 2. In this embodiment, the connection between the linkage push rod and the PACK fixed chassis is realized by the cooperation of two U-shaped fixing buckles and the fixing guide shaft. The fixing guide shaft plays a role of positioning and guiding when connected to the PACK fixed chassis, while the fixing buckle is the actual connection structure.

[0027] More specifically, a connection seat 141 is arranged on the side of the electric telescopic rod 14 close to the fixed rod 11 and is connected to the bottom of the fixed rod 11. The electric telescopic rod is fixed by the connection of a connection seat and the fixed rod.

[0028] More specifically, fixing plates 19 are arranged on both sides of the fixed rod 11 and are connected to the fork tongues of the forklift 3. The fixed rod itself is a detachable structure and is installed on the forklift fork tongue through the fixing plates. When the forklift is not used for the loading and unloading of PACK, it can be disassembled to perform the loading and unloading operations of other goods, thus realizing the convenient disassembly and use of the plug-in mechanism in this embodiment.

[0029] More specifically, the PACK fixed chassis 2 includes two axially arranged guide frames 21, a bottom plate 22, and two radially arranged cross frames 23. The two ends of the guide frame 21 are connected to the two ends of the cross frame 23 and then fixed to the bottom plate 22. A guide groove 211 matching the fixing guide shaft 15 is arranged on the side of the guide frame 21 facing the linkage push rod 12. In this embodiment, the PACK fixed chassis is an installation groove structure, pre-installed at the bottom of PACK to form an integral structure, which is convenient for cooperation with the plug-in mechanism. Among them, a guide groove is arranged on the guide frame to match the fixing guide shaft, guiding the pushing and pulling stroke, which is also a limit to the stroke, preventing it from moving left and right, ensuring the accuracy of the pushing and pulling operation, and also conducive to improving safety.

[0030] More specifically, the bottom plate 22 extends outward on one side of the opening end of the guide groove 211 to form an extension plate, and a fixing column 24 with a hollow internal thread structure is arranged on the extension plate. The specific connection structure between the PACK fixed chassis and the linkage push rod is the fixing column. After connecting the fixing column to the fixing buckle, the position of PACK can be fixed, realizing the loading and unloading operation of the linkage push rod driving PACK to push and pull.

[0031] More specifically, the fixing buckle 17 is provided with a buckle 5 connected to the fixing post 24. The buckle 5 includes a fixing end 51 and a tension plate 52. The tension plate 52 has a rhomboid structure. The fixing end 51 is located at one end of the tension plate 52 and matches the fixing buckle 17. A connecting bolt 53 is provided on the side of the tension plate 52 away from the fixing end 51 and matches the fixing post 24. The specific connection and fixation between the insertion mechanism and the PACK fixing chassis is achieved by setting two buckles. The fixing end of the buckle is inserted into the fixing buckle, and the connecting bolt is connected to the fixing post. The structure is simple and the connection is convenient. In another embodiment, the connecting bolt can be replaced with a pin-type structure integrated with the tension plate, and the fixing post also adopts a hollow structure. The pin-type buckle structure is simpler and more convenient to use.

[0032] More specifically, the bottom of the base plate 22 is provided with several reinforcing ribs 25, and several positioning blocks 26 matching the width of the fork tongue of the forklift 3 are provided on the reinforcing ribs 25. In this embodiment, in order to ensure that the PACK can move smoothly on the fork tongue, several reinforcing ribs are provided to contact the fork tongue, reducing the contact area between the base plate and the fork tongue, thereby reducing the friction during pushing and pulling. At the same time, positioning blocks are provided on the reinforcing ribs, and the spacing between the positioning blocks matches the width of the fork tongue, so that the base plate can be limited during installation and pushing and pulling, ensuring the stability during installation, preventing left and right movement, and improving safety.

[0033] The working principle of this utility model is as follows: The insertion mechanism 1 is installed on the fork tongue of the forklift 3. The PACK fixing chassis 2 is installed on the bottom of the PACK4 as a pre-assembled part, forming an integral structure with the PACK4. At the same time, several lifting rings are provided on the PACK4. During integrated installation, the PACK4 is lifted above the fork tongue and positioned at the front end of the fixed guide shaft 15. The guide groove 211 is aligned with the fixed guide shaft 15 and inserted. At this time, the reinforcing rib 25 contacts the fork tongue. When the PACK fixing chassis 2 is pushed in close to the fixing buckle 17, the fixing end 51 of the buckle 5 is inserted into the fixing buckle 17, and the connecting bolt 53 is connected to the fixing post 24, thereby completing the insertion and fixing of the PACK4. The forklift 3 is then started and moved to the front of the container, and lifted. When the forklift tongue is positioned in the empty PACK slot and aligned with it, the electric telescopic rod 14 is activated, pushing the push rod 16 forward. This, in turn, drives the linkage push rod 12 forward via the stiffening rod 13, thereby pushing the PACK4 forward into the PACK slot. The forklift tongue does not need to enter the slot, effectively optimizing the container's installation space. To remove the PACK4, the operation is reversed: first, push the linkage push rod 13 out to connect with the PACK4, then activate the electric telescopic rod 14 to retract, pulling the PACK4 onto the forklift tongue. Throughout the pushing and pulling process, the latch 5 limits the direction of pushing and pulling to prevent the PACK4 from slipping, while the positioning block 26 prevents the PACK4 from shifting left or right on the forklift tongue and causing an accident.

[0034] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
