[0045] Compared with the prior art, the battery pack is detachably connected to the overhead crane by setting a bracket 1, four hanging arms 21 and four clips 31, wherein the distance between two adjacent hanging arms 21 can be adjusted according to the size specifications of the battery pack, and the clips 31 are clipped to the hanging arms 21 and the battery pack, so that the battery pack can be installed conveniently, and the height of the battery pack from the ground can be adaptively adjusted. The structure is simple and the operation is convenient, and it can solve the technical problem in the prior art that the height of the suspended battery pack from the ground is fixed and cannot be adaptively adjusted because the length of the ring chain is fixed and cannot be adjusted, thereby causing inconvenience in the use of the sling.

[0046] Furthermore, the battery pack is provided with a plurality of mounting holes for installation and fixing, which are conventional arrangements well known to those skilled in the art.

[0047] In this embodiment, the bracket 1 includes two cross beams 11, two longitudinal beams 12 and a reinforcing beam 13. The two cross beams 11 are parallel to each other and are spaced apart. The two longitudinal beams 12 are parallel to each other and are spaced apart between the two cross beams 11, and are respectively connected to the two cross beams 11.

The threaded section of the clamping member 31 passes through the fixing hole of the battery pack and is threadedly connected to the clamping hole 211.

[0061] By using the threaded connection between the bolts and the threaded holes on the suspension arm 21 , the battery pack and the suspension arm 21 can be detachably connected.

[0062] Further, the clamping member 31 here is a bolt or a screw.

[0063] In another embodiment, see Figure 4 The clamping member 31 has a large diameter section and a threaded section. The connecting assembly 3 includes a nut 32. The threaded section of the clamping member 31 passes through the fixing hole and the clamping hole 211 of the battery pack in sequence. The nut 32 is threadedly connected to the threaded section of the clamping member 31.

[0064] The battery pack is clamped on the boom 21 by means of a combination of bolts and nuts 32 .

[0065] In another embodiment, the connection assembly further includes an elastic washer, which is sleeved on the threaded section of the clamp 31 and is disposed between the large diameter section of the clamp 31 and the battery pack.

[0066] The elastic washer is arranged between the large diameter section of the clamping member 31 and the battery pack to reduce damage to the surface of the battery pack when installing and removing the bolts.

[0067] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the utility model is described in detail:

Compared with the prior art, the battery pack is detachably connected to the traveling crane by setting the bracket 1, four hanging arms 21 and four clamping parts 31, wherein the distance between two adjacent hanging arms 21 can be adjusted according to the size specifications of the battery pack, and at the same time, the clamping parts 31 are clamped with the hanging arms 21 and the battery pack, so that the battery pack can be installed conveniently, and the height of the battery pack from the ground can be adaptively adjusted, with a simple structure and convenient operation.

[0069] When in use, the user first installs the hanging hole 16 on the reinforcing beam 13 on the overhead crane, and then connects the block 22 to the other end of the boom 21, so that the block 22 is engaged with the first mounting hole 14 or the second mounting hole 15, and then slightly adjusts the boom 21 to tilt relative to the cross beam 11 and the longitudinal beam 12, so that the battery pack is placed between the four booms 21, and finally the threaded section of the clamp 31 is transmitted to the mounting hole and the clamping hole 211 of the battery pack in sequence, and the nut 32 is threadedly connected to the threaded section of the clamp 31, so that the battery pack is respectively engaged with the four booms 21.
