Description

Technical Field

[0001] This invention relates to the field of battery pack handling technology, and more specifically to a heavy-duty battery pack detachable transport and loading device. Background Technology

[0002] With the continuous development of science and technology, the requirements for equipment are constantly increasing, and therefore the requirements for power systems are also increasing, leading to a continuous increase in the size and weight of battery packs. Heavy-duty battery packs are the power core of large equipment. They are heavy and bulky, making them difficult to transport and assemble. Furthermore, due to the special characteristics of their batteries, heavy-duty battery packs are easily affected by external collisions, temperature changes, and many other factors, which can lead to serious dangers such as short circuits, fires, and explosions.

[0003] Currently used heavy-duty battery pack transport and loading mechanisms are generally too heavy, resulting in high difficulty and cost in transportation and movement. Furthermore, the connection and fastening methods for heavy-duty battery packs are too cumbersome, requiring the disassembly of a large number of screws or other structural components, which greatly increases the labor intensity of operators, reduces assembly efficiency, and also increases the risk of foreign objects falling into the battery pack. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a detachable transport and loading device for heavy-duty battery packs, which solves the problems of excessive weight of the currently used heavy-duty battery pack transport and loading mechanisms, low efficiency of heavy-duty battery pack transport and assembly operations, and low safety of heavy-duty battery pack transport and assembly operations.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0015] In some embodiments, the limiting mechanism includes a plurality of side limiting blocks, a head limiting crossbar, a tail limiting crossbar, a tensioning assembly, and a stop block. The side limiting blocks are detachably mounted on the pressure frame and are used to abut against both sides of the battery pack. The head limiting crossbar is slidably disposed on the pressure frame and is used to connect to one end of the battery pack. The tail limiting crossbar is disposed on the pressure frame and is used to connect to the other end of the battery pack. The tensioning assembly is used to press the head limiting crossbar. A wedge-shaped block is welded on the tail limiting crossbar. The stop block is fixed to the pressure frame and has a wedge-shaped groove that matches the wedge-shaped block.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] To address the technical problems of excessive weight, low efficiency, and low safety in the transport and assembly of heavy-duty battery packs currently used, this invention provides a detachable transport and loading device for heavy-duty battery packs. This device is suitable for transporting and loading heavy-duty battery packs and solves the technical problems of excessive weight making them difficult to move and transport, low efficiency in assembly operations, and low assembly safety.

[0031] Please see Figure 1 , Figure 1 This is a three-dimensional structural diagram of a heavy-duty battery pack detachable transport and loading device according to an embodiment of the present invention. The heavy-duty battery pack detachable transport and loading device includes a bearing mechanism 1, a propulsion mechanism 2, a limiting mechanism 3, and a slide rail mechanism 4.

[0032] The bearing mechanism 1 includes a pressure-bearing frame 11 and a protective frame 12. The pressure-bearing frame 11 and the protective frame 12 are detachably and fixedly connected, and a space for accommodating the battery pack is formed between the pressure-bearing frame 11 and the protective frame 12. In this embodiment, the pressure-bearing frame 11 and the protective frame 12 are locked together by sliding bolts.

[0033] In some embodiments, please refer to Figure 1 The upper protective frame 12 is fixed with multiple lifting rings 121 to facilitate hoisting.

[0034] The propulsion mechanism 2 is used to move the battery pack between the pressure frame 11 and the protective frame 12.

[0035] In some embodiments, please refer to Figures 2-5The propulsion mechanism 2 is mounted on the pressure frame 11. The propulsion mechanism 2 includes two front fixing blocks 21, two rear fixing blocks 22, two lead screws 23, two nuts 24, two driving components 25, and a push block 26. The two front fixing blocks 21 and the two rear fixing blocks 22 are respectively fixed to both ends of the pressure frame 11. The two ends of the two lead screws 23 are respectively rotatably mounted on the two front fixing blocks 21 and the two rear fixing blocks 22. The two nuts 24 are respectively threaded onto the lead screws 23. The two driving components 25 are connected to the two lead screws 23 and are used to drive the lead screws 23 to rotate. The two ends of the push block 26 are respectively fixedly connected to the two nuts 24. The push block 26 is used for detachable fixed connection with the battery pack.

[0036] In some embodiments, please refer to Figures 2-5 The push block 26 is provided with a plurality of first slots 261, which are used to connect with the front crossbeam of the battery pack.

[0037] In some embodiments, please refer to Figures 2-5 The driving component 25 includes a fixed housing 251, a first bevel gear, a second bevel gear, and a handwheel 252. The fixed housing 251 is fixed to the pressure frame 11. The first and second bevel gears are rotatably disposed within the fixed housing 251 and mesh with each other. The first bevel gear is coaxially and fixedly connected to the lead screw 23, and the second bevel gear is fixedly connected to the handwheel 252. In use, rotating the two handwheels 252 synchronously drives the second and first bevel gears to rotate. The first bevel gear drives the lead screw 23 to rotate, and the two lead screws 23 push the push block 26 to move. The push block 26 then pushes the battery pack to move. It should be understood that when the two handwheels 252 rotate synchronously in opposite directions, the function of pulling the battery pack can also be achieved. In this embodiment, by setting the first and second bevel gears, the operating position of the handwheel 252 can be switched to both sides of the pressure frame 11, thereby expanding the operator's field of vision and improving the safety of assembly and docking.

[0038] In this invention, by setting up a propulsion mechanism 2, the heavy battery pack can be moved quickly on the transport loading mechanism, reducing the labor intensity of operators and improving assembly and docking efficiency.

[0039] In some embodiments, please refer to Figures 2-7 The limiting mechanism 3 is installed on the pressure frame 11 and is used to fix the battery pack to the pressure frame 11.

[0040] Specifically, the limiting mechanism 3 includes several side limiting blocks 31, a head limiting crossbar 32, a tail limiting crossbar 33, a tensioning assembly 34, and a stop block 35. The side limiting blocks 31 are detachably installed on the pressure frame 11 and are used to abut against both sides of the battery pack. The head limiting crossbar 32 is slidably disposed on the pressure frame 11 and is used to connect to one end of the battery pack. The tail limiting crossbar 33 is disposed on the pressure frame 11 and is used to connect to the other end of the battery pack. The tensioning assembly 34 is used to press the head limiting crossbar 32. A wedge block 331 is welded on the tail limiting crossbar 33. The stop block 35 is fixed to the pressure frame 11 and has a wedge groove that matches the wedge block 331.

[0041] Specifically, the tensioning assembly 34 includes a base 341 and a push screw 342. The base 341 is fixed to the pressure frame 11. A screw hole is provided on the base 341. The push screw 342 is threaded to the screw hole. One end of the push screw 342 is used to abut against the head limiting crossbar 32.

[0042] Preferably, the tensioning assembly 34 further includes a pad 343, which is fixed to one end of the push screw 342 and is used to abut against the head limiting crossbar 32.

[0043] In use, after the heavy battery pack is inserted, the head limiting crossbar 32 and the tail limiting crossbar 33 are connected to the front and rear crossbeams of the heavy battery pack using a slot structure. The wedge block 331 of the tail limiting crossbar 33 is inserted into the wedge groove. Rotating the push screw 342 presses the head limiting crossbar 32 to achieve locking by the thrust of the push screw 342. When it is necessary to push out the battery pack, first rotate the push screw 342 in the opposite direction to slightly loosen the wedge block 331 of the tail limiting crossbar 33 from the wedge groove. Then remove the head limiting crossbar 32 and the tail limiting crossbar 33. Finally, push out the battery pack through the push mechanism 2.

[0044] Preferably, the side limiting block 31 is provided with a first fixing groove, and the pressure frame 11 is provided with a second fixing groove. The first fixing groove and the second fixing groove are connected by bolts, so that the side limiting block 31 can be detachably connected to the pressure frame 11.

[0045] Preferably, guide wheels 36 are fixed at both ends of the tail limiting crossbar 33. At the same time, the limiting structure can be modularly replaced for different working conditions. In the case of scenarios that require quick docking and limiting to realize transportation loading, the guide wheels 36 can be replaced with automatic hooks (such as Jameson hooks). The automatic hooks are installed on the stop block 35 with screws, and then the corresponding hooks on the heavy battery pack push to realize the quick docking and locking of the heavy battery pack with the loading mechanism.

[0046] like Figure 4 As shown, the slide rail mechanism 4 is mounted on the pressure frame 11, and the slide rail mechanism 4 is used to place the battery pack.

[0047] Specifically, the slide rail mechanism 4 includes a bottom guide rail 41 and a side guide rail 42. The bottom guide rail 41 is mounted on the pressure frame 11, and a plurality of bottom rollers 411 are rotatably connected to the bottom guide rail 41. The bottom rollers 411 are used to place the battery pack. The side guide rail 42 is mounted on the pressure frame 11, and a plurality of side rollers 421 are rotatably connected to the side guide rail 42. The side rollers 421 are used to abut against the side wall of the battery pack.

[0048] By setting multiple bottom rollers 411, the weight of the heavy battery pack can be evenly distributed, while ensuring that the heavy battery pack can move quickly. By setting side rollers 421, the direction of movement of the heavy battery pack is restricted, improving the stability of movement. The roller structure can greatly reduce the movement resistance and improve the assembly and debugging efficiency.

[0049] The beneficial effects of the technical solution proposed in this invention patent include:

[0050] (1) The slide rail mechanism 4 carries the heavy battery pack. The heavy battery pack is connected to the push mechanism 2 to move. The heavy battery pack is fixed on the pressure frame 11 by the limiting mechanism 3. At the same time, the pressure frame 11 is connected and fixed to the protective frame 12 for transportation and hoisting. The upper and lower parts of the carrying mechanism 1 can be separated, which facilitates assembly and transportation hoisting and moving. The optimized carrying mechanism 1 greatly reduces the weight of the transportation loading mechanism. The limiting mechanism 3 achieves complete fixation of the heavy battery pack on the carrying mechanism 1 through the side limiting block 31, the head limiting crossbar 32, and the tail limiting crossbar 33, which improves the safety of transportation and movement. At the same time, the limiting mechanism 3 can be directly and quickly disassembled after use, which increases the assembly and debugging operation space and improves the assembly operation efficiency.

[0051] (2) The propulsion mechanism 2 can move the heavy battery pack through the screw nut, and can achieve a wider field of vision and a safer operating position for the operator through the bevel gear steering, thereby reducing the labor intensity of the operator;

[0052] (3) The slide rail device uses multiple rollers to enable the heavy battery pack to bear pressure and move, ensuring that the heavy battery pack can be moved conveniently on the transport loading mechanism and improving docking and assembly efficiency; the support frame adopts welding process, and most of the other mechanisms adopt slot design, avoiding the risk of foreign objects falling into the battery pack caused by screw disassembly and other operations.

[0053] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
