Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting equipment, and specifically relates to an adjustable battery pack hoisting tool. Background Art

[0002] As the social economy develops rapidly, there is also a global energy shortage. More and more new energy vehicles on the road will gradually replace oil vehicles. From small family cars to large heavy trucks, the fuel tanks will eventually be replaced with power battery packs.

[0003] A power battery pack is composed of multiple battery cells connected in series and parallel to form a battery module, which is then composed of multiple battery modules connected in series and parallel to form a power battery pack. Finally, multiple battery packs are placed in a battery frame. The weight of each battery pack ranges from 200 to 500 kg. With the rapid development of energy storage, people have higher and higher requirements on the storage capacity of energy storage devices. At the same time, the weight of battery packs will become heavier. Manual handling of battery packs is very inefficient. The commonly used battery pack lifting tools on the market are generally composed of pull rods and lifting rings. This tool has the following defects: 1. The lifting tool cannot be adjusted, and one tool can only be used for one specification and model of battery pack; 2. When the tool lifts the battery pack, an inner extrusion pressure will be generated between the sling and the tool. This extrusion pressure will not only cause varying degrees of damage to the battery pack shell, but also cause the pull rod of the lifting tool to break. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an adjustable battery pack hoisting tool to overcome the defects of the existing battery pack hoisting tool technology, adopt an adjustable structure, can be applied to battery packs of different specifications, and save the cost of producing tooling. At the same time, the battery pack shell is not squeezed and damaged, thereby protecting the pull rod from breaking.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an adjustable battery pack lifting tool, including a lifting lug and a sliding assembly, and the sliding assembly includes a transverse slide rail and two longitudinal slide rails.

[0006] The transverse slide rail has a first groove, and the two longitudinal slide rails each have a second groove.

[0007] Two first sliders are slidably connected in the first groove, and two second sliders are slidably connected in the second groove; the two first sliders are respectively fixed on the transverse slide rail; a T-shaped slot is provided at the bottom of the second slider, and a pull rod is connected to the T-shaped slot.

[0008] The lifting ears are provided with two pairs and are symmetrically fixed on two longitudinal slide rails respectively.

[0009] The bottom end of the pull rod is processed with a connecting thread for fixing and connecting the battery pack. The pull rod is made of 42CrMo material.

[0010] Furthermore, it also includes a first screw and a second screw, wherein the threads of the first screw and the second screw are based on the center of the screw, and the rotation directions of the threads are opposite.

DETAILED DESCRIPTION

[0021] The following will provide a clearer understanding of the technical features, purposes and effects of the present invention. The specific implementation methods of the present invention are now described with reference to the accompanying drawings. Those skilled in the art should understand that the following does not constitute a limitation on the protection scope of the present invention.

[0022] Examples, such as Figure 1-Figure 2 As shown, an adjustable battery pack lifting tool includes a lifting ear 1 and a sliding assembly, and the sliding assembly includes a transverse slide rail 2 and two longitudinal slide rails 3.

[0023] The transverse slide rail 2 has a first groove 21 , and the two longitudinal slide rails 3 each have a second groove 31 .

[0024] Two first sliders 5 are slidably connected in the first groove 21 , and two second sliders 6 are slidably connected in the second groove 31 ; the two first sliders 5 are respectively fixed on the transverse slide rail 2 ; a T-slot 61 is provided at the bottom of the second slider 6 , and a pull rod 7 is connected to the T-slot 61 .

[0025] Two pairs of lifting ears 1 are provided and are symmetrically fixed on two longitudinal slide rails respectively.

[0026] A connecting thread 71 is processed at the bottom end of the pull rod 7 for fixing and connecting the battery pack, thereby enhancing the stability of the lifting and facilitating quick installation and disassembly.

[0027] The pull rod 7 is made of 42CrMo material and has been tempered. It can withstand the high load and complex stress during the lifting process. The lifting tooling only bears downward pulling force and does not cause extrusion damage to the battery pack shell, thereby protecting the pull rod from breakage. It can effectively avoid problems such as breakage during the lifting of the battery pack.

[0028] It also includes a first screw 9 and a second screw 10. The threads of the first screw 9 and the second screw 10 are symmetrically processed based on the center of the screw, and the rotation directions of the threads are opposite.

[0029] The first slider 5 is provided with a first threaded hole 51 , and the second slider 6 is provided with a second threaded hole 62 .

[0030] Both ends of the first lead screw 9 pass through the first threaded holes 51 to be symmetrically connected to the first slider 5 , and both ends of the second lead screw 10 pass through the second threaded holes 62 to be symmetrically connected to the second slider 6 .

[0031] When the first lead screw 9 rotates, the two first sliders 5 can synchronously realize the opening and closing function. Similarly, when the first lead screw 10 rotates, the two second sliders 6 can synchronously realize the opening and closing function, thereby adjusting the distance between the pull rods 7 to adapt to battery packs of various specifications and shapes, thereby improving the accuracy and stability of the adjustment.

[0032] End covers 8 are provided at both ends of the transverse slide rail 2 and the longitudinal slide rail 3. Bearings 11 are provided inside the end covers 8 and are sleeved on the first lead screw 9 and the second lead screw 10. The bearings 11 are used to support the first lead screw 9 and the second lead screw 10, which not only reduces the friction resistance but also extends the service life of the lead screw. The end covers 8 not only protect the bearings 11 but also prevent the entry of dust and impurities, thereby ensuring the cleanliness and operating efficiency of the tooling.

[0033] Hand wheels 4 are installed at both ends of the first screw 9 and the second screw 10 . The hand wheels 4 can rotate the first screw 9 and the second screw 10 to achieve precise adjustment of the first slider 5 and the second slider 6 .

[0034] Working principle: Connect the tooling to the lifting equipment through the lifting lug 1 to ensure that the tooling is firmly suspended. Longitudinal adjustment: Shake the handwheel 4 to rotate the first screw 9, so that the two first sliders 5 slide synchronously on the transverse slide rail 2, thereby adjusting the longitudinal spacing of the pull rod 7. Transverse adjustment: Shake the handwheel 4 to rotate the second screw 10, so that the two second sliders 6 slide synchronously and in opposite directions on the longitudinal slide rail 3, and drive the pull rod 7 to adjust horizontally through the T-slot 61. By adjusting the spacing between the pull rods 7, the specifications of the battery pack to be hoisted are matched. After the spacing is adjusted, align the connecting thread at the bottom of the pull rod 7 with the corresponding threaded hole on the battery pack and tighten it to ensure that the battery pack is firmly connected to the pull rod. Start the lifting equipment and hoist the battery pack to the specified position.
