[0032] One of the core components of an electric vehicle is the power battery pack. During the production and manufacturing process of the battery pack, it is necessary to use a crane in cooperation with a lifting tool to lift and move the battery pack to achieve purposes such as transportation, transfer, and assembly. However, the frame of the existing battery lifting tool can only cooperate with the crane for lifting and moving. Since the steps of lifting and moving through the crane are cumbersome and the crane has low efficiency, it is impossible to quickly transfer the battery pack.

[0033] Based on the above problems, the embodiments of the present disclosure provide a lifting tool frame. The first beam body and the second beam body vertically connected to the lifting tool frame can improve the overall strength of the present application. And the fork channels on the two fork assemblies vertically connected to the two second beam bodies can allow the two forks of a forklift to be inserted into the fork channels to quickly complete the lifting and moving of the lifting tool frame.

[0034] Figure 1 Shown herein is a schematic diagram of the overall structure of the spreader frame in an embodiment of the present disclosure. In Figure 1 the example, the spreader frame includes two first beam bodies 10, two second beam bodies 20, and two fork assemblies 30. The two first beam bodies 10 are arranged in parallel and at intervals. The two second beam bodies 20 are arranged in parallel and at intervals, and are perpendicularly connected to the two first beam bodies 10. The two fork assemblies 30 are arranged in parallel and at intervals, and are perpendicularly connected to the two second beam bodies 20; each fork assembly 30 forms a fork channel 301 along its length direction.

[0035] The advantage of the above arrangement is that the overall strength of the present application can be improved by the first beam body 10 and the second beam body 20 perpendicularly connected on the spreader frame. The fork channels 301 on the two fork assemblies 30 perpendicularly connected to the two second beam bodies 20 can, in an emergency, allow the two forks of a forklift to be inserted into the fork channels 301 to quickly complete the lifting and moving of the spreader frame.

[0036] Figure 2 Shown herein is a cross-sectional schematic diagram of the overall structure of the spreader frame in an embodiment of the present disclosure. Figure 3 Shown herein is a cross-sectional schematic diagram of the overall structure of the spreader frame from another perspective in an embodiment of the present disclosure. In Figure 2 and Figure 3 the example, the first beam body 10 and the second beam body 20 are both implemented as square tubes, which can reduce the overall weight of the spreader frame while improving the overall strength of the spreader frame, thereby reducing the load on the crane or forklift. In another embodiment, the first beam body 10 and the second beam body 20 are implemented as round tubes.

[0037] Exemplarily, the two second beam bodies 20 are perpendicularly connected to the vertical side walls of the first beam body 10. And the two fork assemblies 30 are arranged on the top of the second beam bodies 20 to facilitate the forks of the forklift to cooperate with the fork channels 301 of the two fork assemblies 30.

[0038] Further exemplarily, the distance between the two fork assemblies 30 is adapted to the distance between the two forks of the forklift. If the length of the second beam body 20 is too small, the two fork assemblies 30 can also be connected to the tops of the two first beam bodies 10. If the length of the engaging member is less than the length of the fork, the fork channel 301 is formed through the fork assembly 30.

[0039] In Figure 1In the example, the sling frame includes a reinforcing beam 40; the reinforcing beam 40 is vertically connected to the two second beam bodies 20. The arrangement of the reinforcing beam 40 can further improve the overall strength of the sling frame.

[0040] Exemplarily, the reinforcing beam 40 is located at the middle position between the two first beam bodies 10. Exemplarily, the sling frame further includes a suspension member 50 disposed at the middle position of the reinforcing beam 40. The advantage of such an arrangement is to ensure that the suspension member 50 is at the center of gravity position of the sling frame, so that when the sling frame is lifted and moved in cooperation with the suspension member 50 by a crane, the sling frame maintains a state of stable center of gravity, avoiding accidents due to the unstable center of gravity of the sling frame.

[0041] In Figure 2 In the example, the suspension member 50 includes a fixing member 51 and a suspension ring 52; the fixing member 51 is detachably disposed at the middle position of the reinforcing beam 40, and the suspension ring 52 is hinged to the top of the fixing member 51. Further exemplarily, the fixing member 51 includes a clamping frame 511 with an opening and a fixing plate 512; the suspension ring 52 is hinged to the top of the clamping frame 511; the reinforcing beam 40 is clamped in the opening of the clamping frame 511, and the fixing plate 512 is bolted to the clamping frame 511 to block the opening.

[0042] Those skilled in the art can understand that after the sling frame is lifted off the ground by a crane, the operator can rotate the first beam body 10 or the second beam body 20 to integrally rotate the sling frame and the battery pack clamped below to adjust the placement direction of the battery pack.

[0043] Exemplarily, a rubber pad (not shown in the figure) is provided on the inner wall surface of the opening of the clamping frame 511. To improve the fixing effect between the clamping frame 511 and the reinforcing beam 40.

[0044] In Figure 1 In the example, the sling frame further includes at least a pair of handrails 60, and the at least a pair of handrails 60 are symmetrically connected to the vertical side walls of the two first beam bodies 10 or the second beam bodies 20. Exemplarily, the sling frame includes a pair of handrails 60, and the at least a pair of handrails 60 are symmetrically connected to the vertical side walls of the two second beam bodies 20. Exemplarily, the handrail 60 is implemented as a broken line type. In another embodiment, the handrail 60 is implemented as a straight line type extending outward along the vertical side wall of the second beam body 20.

[0045] Further exemplarily, after the pair of armrests 60 are installed, the length of the distance between the two second beam bodies 20 and the sum of the lengths of the two armrests 60 are not greater than the length of the first beam body 10, so as to prevent the armrests 60 from protruding from the first beam body 10 and improve the integrity of the spreader frame.

[0046] In another embodiment, the armrests 60 are implemented as two pairs. The vertical side walls of the two first beam bodies 10 and the two second beam bodies 20 are all connected to a pair of armrests 60.

[0047] In Figure 1 the example, the spreader frame includes a plurality of reinforcing rib plates 70. At least one of the reinforcing rib plates 70 is provided at the connection between the first beam body 10 and the second beam body 20 and at the connection between the fork member 30 and the second beam body 20. Exemplarily, the reinforcing rib plates 70 are welded to the spreader frame. Further exemplarily, the reinforcing rib plates 70 are implemented as right-angled triangles, and the two right-angled sides of the reinforcing rib plates 70 abut against the side walls of the first beam body 10 and the second beam body 20 or the side walls of the second beam body 20 and the fork member 30.

[0048] In yet another embodiment of the present disclosure, a battery pack spreader is provided, which includes the spreader frame and a plurality of suspension components. The plurality of suspension components are provided at different positions of the spreader frame.

[0049] In summary, in the embodiments of the present disclosure, a spreader frame and a battery pack spreader thereof are provided. The spreader frame includes two first beam bodies that are parallel and spaced apart; two second beam bodies that are parallel and spaced apart and are vertically connected to the two first beam bodies; two fork members that are parallel and spaced apart and are vertically connected to the two second beam bodies; and each of the fork members forms a fork channel along its length direction. The battery pack spreader includes the spreader frame and a plurality of suspension members, and the plurality of suspension members are provided at different positions of the spreader frame. The advantage of the above arrangement is that the overall strength of the present application can be improved by the first beam body and the second beam body that are vertically connected on the spreader frame. And the fork channels on the two fork members that are vertically connected to the two second beam bodies can enable the two forks of the forklift to be inserted into the fork channels, so as to quickly complete the lifting and moving of the spreader frame.

[0050] The above embodiments are only used to illustrate the principles and effects of the present disclosure, rather than to limit the present disclosure. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present disclosure should still be covered by the protection scope of the present disclosure.
