Description

Technical Field

[0001] This utility model relates to the field of hoisting devices, and in particular to a hoisting device for energy storage battery packs, which is suitable for efficient and safe hoisting operations during the production, transportation and installation of energy storage battery packs. Background Technology

[0002] With the rapid development of the new energy industry, energy storage battery packs are widely used due to their high energy density and modular design. Lifting operations are an indispensable part of the production, transportation, and installation of battery packs. Currently, the lifting of energy storage battery packs mainly relies on manual operation, which has the following significant drawbacks:

[0003] Poor safety: In traditional lifting equipment, hook installation relies on manual operation, requiring the hook to be manually secured to the four corner lifting points of the battery pack. During operation, the hook and battery pack must be manually kept fixed until they are stably lifted. If the hook is released before the battery pack is fully and stably lifted, there is a risk of the hook falling off, causing the battery pack to fall. Furthermore, operators face significant safety risks such as being pinched or crushed during the operation, making the safety hazards particularly pronounced.

[0004] Inefficient: The hoisting process requires the cooperation of multiple people (usually 3-5 people), resulting in high labor costs and difficulty in coordination, making it difficult to adapt to the needs of large-scale production.

[0005] Complex operation: The existing equipment lacks a quick fixing mechanism for the hook, resulting in a complicated operation process that takes a long time.

[0006] Currently, a mainstream traditional battery pack hoisting device on the market uses manually tightened bolts to secure the hooks. While this solves the stability problem to some extent, it still requires manual installation and fixation by operators. Furthermore, this traditional battery pack hoisting device fails to eliminate the safety hazard of battery pack detachment. Therefore, there is an urgent need for a more efficient, convenient, and safer energy storage battery pack hoisting device. Utility Model Content

[0007] To address the shortcomings of the aforementioned technologies, this utility model provides an energy storage battery pack hoisting device.

[0008] To solve the above technical problems, the technical solution adopted by this utility model is: an energy storage battery pack hoisting device, including a hoisting frame, the hoisting frame being connected to a main hoisting rope through a main hoisting ring set at its center point; the hoisting frame being connected to a side plate through a secondary hoisting ring installed at its end point; lifting ropes being symmetrically connected to the bottom end of the side plate; and a hook assembly being connected to the end of the lifting rope, the hook assembly being provided with a spring clamping plate structure.

[0009] Furthermore, the hoisting frame includes a frame body, with a main lifting ring installed at the upper end of the center point of the frame body; the frame body is connected to four booms, which are distributed in an "X" shape with the frame body (101) as the center; the main lifting ring is installed at the upper end of the frame body, and secondary lifting rings are installed at the ends of the booms.

[0010] Furthermore, the side plate is trapezoidal, with two side plate fixing blocks symmetrically arranged on the short side at the top, and multiple sets of rope hanging holes on the same horizontal plane on the long side at the bottom, with lifting ropes connected to the hanging holes.

[0011] Furthermore, the side plate fixing block is fixed to the side plate with bolts; the side plate fixing block is equipped with a lifting shackle, and the side plate is connected to the lifting frame by being inserted into the secondary lifting rings of two adjacent booms through the lifting shackle.

[0012] Furthermore, the hook assembly includes a hook body, the hook body being in the shape of... The structure is shaped like a lifting ring installed at the top; a bottom opening is provided at the bottom; a middle plate extends from the middle part, and two bolt through holes are provided on the middle plate; the lifting ring is connected to a lifting rope.

[0013] Furthermore, the spring clamp device includes a spring clamp, which is placed parallel to the groove between the intermediate plate and the bottom end of the hook body.

[0014] Furthermore, the spring clamp is connected to the hook body via bolts passing through the bolt holes in the intermediate plate.

[0015] Furthermore, the spring clamping device also includes a spring, which is disposed between the intermediate plate and the spring clamping plate, and the spring is sleeved on the bolt.

[0016] This invention provides a lifting device for energy storage battery packs, aiming to solve the problems of traditional energy storage battery pack lifting devices in terms of labor costs, safety, and efficiency. The device adds a side plate structure between the lifting frame and the hook, allowing the side plate to act as a buffer during battery pack lifting operations, reducing the swaying amplitude of the battery pack and thus lowering the risk of battery pack detachment, enhancing the safety of the lifting operation. Furthermore, the hook assembly is equipped with a spring clamping device, allowing only one operator to complete the hook installation. The spring clamping device automatically fixes the hook to the battery pack, significantly improving the convenience and efficiency of operation. Therefore, this device provides an efficient, convenient, and safe solution for battery pack lifting. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 The diagram shows a hoisting device for an energy storage battery pack, comprising a hoisting frame 1, a main lifting ring 4 at the upper center of the hoisting frame 1, and a main lifting rope connected to the hoisting frame 1 via the main lifting ring 4; secondary lifting rings 5 ​​are provided at each of the four ends of the hoisting frame 1. Specifically, as shown... Figure 2 As shown, the lifting frame 1 includes a frame body 101, with a main lifting ring 4 at the center of the frame body 101 and an upper ring at the top. The frame body 101 is connected to four booms 102, which are arranged in an "X" shape around the frame body, and are integrally formed with the frame body 101. Secondary lifting rings 5 ​​with lower rings are installed at the ends of the four booms 102. Side plate structures are connected to the secondary lifting rings 5 ​​at the ends of the booms, and these side plate structures are connected to the hook assembly 3 via lifting ropes 8.

[0024] In this embodiment, as Figure 2 The side panel structure shown includes a trapezoidal side panel 2 with two symmetrically arranged side panel fixing blocks 6 on both sides of its top short side. Multiple arrays of rope hanging holes 9 are arranged horizontally along the bottom long side of the side panel 2. This structural design allows for flexible adaptation of the lifting spacing parameters by adjusting the connection position of the lifting rope 8 with the rope hanging holes 9, thereby meeting the shape matching requirements of battery packs of different specifications. This design flexibility allows for adjustments according to different lifting needs.

[0025] Furthermore, the side plate 2 and the side plate fixing block 6 are fixedly connected by bolts. The curved end of the side plate fixing block 6 also has an opening for installing the lifting shackle 10. The side plate structure is connected to the lifting frame 1 by inserting the secondary lifting ring 5 through the lifting shackle 10. The function of the side plate structure is to extend the distance between the two hooks, so that it is no longer limited to the distance between the ends of the two booms of the lifting frame. This design improves the operational flexibility of the lifting device and reduces the possibility of needing to replace the lifting device due to a significant mismatch between the lifting frame and the dimensions of the object being lifted. Simultaneously, during the lifting operation, the side plate structure can provide some interception for the battery pack, effectively reducing the degree of swaying of the battery pack during the lifting operation. This interception further improves the stability and safety of the entire lifting device, ensuring the safe conduct of the lifting operation.

[0026] like Figure 3 The hook assembly 3 shown includes a hook body 31. The hook body 31 is as follows... Figure 4 As shown, The structure has a large thickness at the top and a hole for installing the lifting ring 7, which is used to connect the lifting rope 8; the bottom end has a bottom opening 33; an intermediate plate 32 extends between the grooves of the hook body, and two bolt through holes 11 are opened on the intermediate plate 32.

[0027] Preferably, the hook assembly 3 is further provided with a spring clamping device, which includes a spring clamping plate 12, which is placed parallel to the middle plate 32 and the bottom end of the hook body; two bolts 15 are inserted into the bolt through holes 11 of the middle plate 32 and are fixedly connected to the spring clamping plate 12. It should be noted that the diameter of the bolt through hole 11 is larger than that of the bolt 13, and the bolt 13 and the spring clamping plate 12 are threaded. This bolt is a movable bolt for the hook body (or middle plate) and can move up and down in the hook groove; the middle plate only restricts the movement of the bolt and the spring clamping plate.

[0028] Furthermore, a spring 14 is provided between the spring clamp 14 and the intermediate plate 32, and the spring 14 is sleeved on the bolt 13 that is threadedly connected to the spring clamp 12. It should be noted that one end of the spring 14 abuts against the lower end face of the intermediate plate 32, and the other end abuts against the upper end face of the spring clamp 12. In the unloaded state, the spring clamp device gradually approaches the bottom end of the hook body under the action of the elastic potential energy of the spring 14, that is, the spring clamp 12 and the bolt 13 threadedly connected to it move downward under the action of the spring 14 until the nut of the bolt 13 abuts against the intermediate plate 32.

[0029] The specific method of using this hook assembly 3 is as follows: The operator presses the spring clamp 12 of the hook assembly upwards, compressing the spring 14. The spring clamp 12 and the bottom end of the hook body form a recessed space, which is then inserted into the bottom support tray of the energy storage battery panel. The spring clamp 12 is then released. Under the force of the spring 14, the spring clamp 12 will move downwards until the hook assembly 3 clamps the battery pack support tray.

[0030] Preferably, the bottom opening of the hook body can be inserted into the protrusion of the support tray, or the connection between the hook and the support tray can be secured using a lock, knot, or other means.

[0031] Traditional energy storage battery pack hoisting equipment requires multiple operators to hold the hook up as the battery pack rises until the hoisting rope is taut. During this process, operators face risks such as being pinched. In addition, the large number of operators makes coordination difficult, resulting in low hoisting efficiency.

[0032] Compared to traditional energy storage battery pack hoisting devices, the hooks of this invention are equipped with a spring clamping structure, requiring only one operator to install four hooks in turn. The hooks automatically clamp the hoisted object through the spring clamping device, making it more stable than hook-type hooks and more convenient than bolt-fixed hooks. At the same time, the hoisting device of this invention also adds a side plate structure, which reduces the possibility of the hoisted object falling by intercepting the swing of the hoisted object.

[0033] In summary, this utility model effectively solves the problems of labor cost, safety, and efficiency in traditional energy storage battery pack hoisting devices by adding side plate structures to the hoisting frame and adding spring clamps to the hooks, and provides an efficient, convenient, and safe energy storage battery pack hoisting solution.

[0034] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
