[0020] First, it needs to be explained that the utility model discloses the direction word such as upper, lower, left, right, front, back is only according to the description of the drawing, to facilitate understanding, and not to the technical scheme of the utility model and the protection range of request limit.

[0021] As Figures 1 to 6 The utility model discloses a rotary battery hooking device's specific embodiment, including intermediate connecting seat 1 and corresponding left connecting seat 2 and right connecting seat 2' at the both sides of intermediate connecting seat 1. Install vertical left rotating shaft 3 on left connecting seat 2, fix left lifting claw 4 at the lower end of left rotating shaft 3, and set left cylinder 5 between left lifting claw 4 and intermediate connecting seat 1. Correspondingly, install vertical right rotating shaft 3' on right connecting seat 2', fix right lifting claw 4' at the lower end of right rotating shaft 3', and set right cylinder 5' between right lifting claw 4' and intermediate connecting seat 1.

[0022] ​​The above configuration constitutes a compact, easy-to-operate, sensitive, stable, reliable, and highly practical rotary battery hooking device. In practical applications, two sets of rotary battery hooking devices are installed at intervals along the front-to-back direction at the bottom of the docking frame of the battery hoist. The middle connecting seat 1, left connecting seat 2, and right connecting seat 2' are fixed on the docking frame. When hoisting the battery, the battery hoist is first moved to directly above the battery pack by a gantry crane, and then the battery hoist is lowered onto the battery pack by the gantry crane. The side beam of the docking frame of the battery hoist overlaps with the side beam of the support frame of the battery pack. Then, the corresponding lifting claws (left lifting claw 4 and right lifting claw 4') are driven by each cylinder (left cylinder 5 and right cylinder 5') to rotate to the underside of the side beam of the support frame to hook the battery pack, thus connecting the battery hoist and the battery pack. To disconnect the battery hoist and the battery pack, simply rotate each lifting claw back to its initial position. Compared with the prior art, this utility model eliminates the need for transmission mechanisms such as slide plates, guide holes, rollers, guide rails, and sliders by setting up a middle connecting seat, a left connecting seat, and a right connecting seat, and by having the left cylinder 5 and the right cylinder 5' directly drive the corresponding left lifting claw 4 and right lifting claw 4' to rotate. This simplifies the structure, improves compactness, and helps reduce the overall height of the battery lifting device. Furthermore, it improves the sensitivity and reliability of the operation. In practical applications, this utility model typically arranges the left connecting seat 2 and the right connecting seat 2' in a symmetrical distribution, that is, symmetrically positioned on the left and right sides of the middle connecting seat 1 to improve structural stability and balance. Similarly, this utility model also adopts a symmetrical arrangement for the left lifting claw 4 and the right lifting claw 4', that is, symmetrically positioned on the left and right sides of the middle connecting seat 1. To ensure that the left cylinder 5 and the right cylinder 5' can drive the left claw 4 and the right claw 4' to rotate normally, the axis of the left cylinder 5 should be offset from the axis of the left rotating shaft 3. That is, a gap should be set between the axis of the left cylinder 5 and the left rotating shaft 3. Similarly, a gap should also be set between the axis of the right cylinder 5' and the right rotating shaft 3'.

[0023] In a specific embodiment, this utility model fixes an L-shaped bracket 11 to the front side of the intermediate connecting seat 1, and fixes a left hinge 41 and a right hinge 41' to the inner sides of the left lifting claw 4 and the right lifting claw 4', respectively. The cylinder body of the left cylinder 5 is connected to the L-shaped bracket 11 via a pin, and the piston rod of the left cylinder 5 is connected to the left hinge 41 via a pin. The cylinder body of the right cylinder 5' is connected to the L-shaped bracket 11 via a pin, and the piston rod of the right cylinder 5' is connected to the right hinge 41' via a pin. This structure, by setting the L-shaped bracket 11, the left hinge 41, and the right hinge 41', improves the ease of connection. By using a hinged connection between the left cylinder 5 and the right cylinder 5', the smooth operation of the left lifting claw 4 and the right lifting claw 4' is ensured. To facilitate installation and fixation, this embodiment features a central mounting plate 12 at the top of the central connecting seat 1, a left mounting plate 21 fixed to the top of the left connecting seat 2 with screws, and a right mounting plate 21' fixed to the top of the right connecting seat 2' with screws. Countersunk holes for mounting bolts are provided on the central mounting plate 12, left mounting plate 21, and right mounting plate 21', allowing the central connecting seat 1, left connecting seat 2, and right connecting seat 2' to be fixed to the docking frame side beam of the battery hanger using bolts. To enhance the stability of the connection, this embodiment also features an upwardly extending left side plate 22 on the left side of the left connecting seat 2 and an upwardly extending right side plate 22' on the right side of the right connecting seat 2'. Bolt holes and pin holes are provided on the left side plate 22 and right side plate 22', allowing the left side plate 22 and right side plate 22' to be fixed to the docking frame side beam of the battery hanger using bolts, and pins installed in the pin holes for auxiliary positioning and fixation.

[0024] In a specific embodiment, this utility model adopts a sloping structure with a lower front and higher rear at the lower end of the intermediate connecting seat 1. This provides longitudinal guidance and positioning when the battery lifting device is docked with the battery pack. A longitudinal protective plate 13 is fixed to the sloping surface and rear side of the intermediate connecting seat 1 to reduce noise and wear. The battery pack's support frame has a crossbeam that cooperates with the intermediate connecting seat 1. Similarly, in this specific embodiment, a left transverse protective plate 23 is fixed to the left side of the left connecting seat 2, and a triangular left protective block 42 is fixed to the left side of the left lifting claw 4; a right transverse protective plate 23' is fixed to the right side of the right connecting seat 2', and a triangular right protective block 42' is fixed to the right side of the right lifting claw 4'. This arrangement provides lateral guidance and protection when the battery lifting device is docked with the battery pack through the left transverse protective plate 23, left protective block 42, right transverse protective plate 23', and right protective block 42'. The side beams of the battery pack's support frame limit the movement of the left connecting seat 2 and the right connecting seat 2'. In practical applications, the present invention typically uses composite rubber to make the longitudinal protective plate 13, the left transverse protective plate 23, the left protective block 42, the right transverse protective plate 23', and the right protective block 42'.
