In this embodiment, when the driving device drives the power battery 200 to move down to the position where the two hanging claws 141 are lower than two opposite sides of the power battery 200, the hand wheel 1421 is rotated to drive the screw 1422 to rotate, and then drive the adjusting nut 1423 to lift along the extending direction of the screw 1422, the angle between the two connecting rods 1424 can be gradually reduced during the lifting of the adjusting nut 1423, and then the two hanging claws 141 are driven to tighten more smoothly, so as to clamp the power battery 200 smoothly, thus, the power battery 200 is not clamped too much, and the two hanging claws 141 are not loosened too much to slip the power battery 200. And, when the power battery 200 needs to be released, only the hand wheel 1421 is required to be rotated in a direction to drive the screw rod 1422 to rotate, and then the adjusting nut 1423 is driven to descend along the extending direction of the screw rod 1422, and the angle between the two connecting rods 1424 can be driven to gradually increase during the descending of the adjusting nut 1423, and then the two hanging claws 141 are driven to be opened more smoothly, so that the power battery 200 is released smoothly.

In an embodiment of the present application, referring to fig. 1 and 3 in combination, a locknut 1425 is further sleeved on the screw 1422.

Locknut 1425 may be a wing nut 132. Locknut 1425 may be located above adjustment nut 1423 or below adjustment nut 1423.

In this embodiment, after the power battery 200 is clamped by the two hanging claws 141, the locknut 1425 on the screw rod 1422 is screwed to lock the adjusting nut 1423 at the corresponding position, so that the adjusting nut 1423 can be prevented from moving relative to the screw rod 1422 under the action of external force in the carrying process, and the clamping effect of the two hanging claws 141 on the power battery 200 is prevented from being affected.

In an embodiment of the present application, referring to fig. 1, 3 and 5, the opposite sides of the power battery 200 are provided with flanges 20c, the hanging claws 141 are provided with clamping grooves 1411, and each clamping groove 1411 is used for being matched with one flange 20c in a clamping manner when the two hanging claws 141 are tightened.

The flange 20c may be a bar-like structure extending from the front end of the power cell 200 to the rear end of the cell; the convex edge 20c may have a block-shaped structure extending from the middle of the power cell 200 to both sides.

In this embodiment, each convex edge 20c on the power battery 200 will be snapped into the clipping groove 1411 on each convex edge 141 during tightening of the two hanging claws 141, so that the limiting effect of the hanging claws 141 on the power battery 200 is further improved under the cooperation of the convex edge 20c and the clipping groove 1411, so as to further improve the anti-falling effect on the power battery 200.

In an embodiment of the present application, referring to fig. 1, fig. 2, and fig. 5 in combination, an outer contour of the frame 11 is a rectangular structure, four first lifting lugs 111 are provided, connecting lines between the four first lifting lugs 111 form the rectangular structure, and a center line of the frame 11 coincides with a center line of the rectangular structure formed by connecting lines between the four first lifting lugs 111.

The connection between the four first lifting lugs 111 and the frame 11 may be the same or different. For example, four first lifting lugs 111 may be connected to the frame 11 by means of screw connections; as another example, two of the four first lifting lugs 111 are connected to the frame 11 by means of screw connection, and the other two can be connected to the frame 11 by means of snap connection.

In this embodiment, four first lifting lugs 111 are connected to the frame 11, and the center line of the frame 11 coincides with the center line of the rectangular structure formed by the connecting lines between the four first lifting lugs 111, so that when the four first lifting lugs 111 are connected with the crane, the crane can drive the whole power battery 200 to move in a balanced manner through the four first lifting lugs 111, and further can drive the power battery 200 to move more stably, so as to improve the balance of the power battery 200 in the moving process.

In an embodiment of the present application, referring to fig. 1, 2 and 5 in combination, each first lifting lug 111 is used for connecting with a crane through a lifting rope.

The bottom end of each lifting rope can be directly tied to one first lifting lug 111 in a knotting mode, and the top end of each lifting rope can also be directly tied to the lifting hook of the crane in a knotting mode. Of course, the bottom end of the lifting rope may be tied to a connecting buckle, and then the connecting buckle is buckled on the first lifting lug 111; the top end of the lifting rope can be tied on a connecting buckle, and then the connecting buckle is tied on the lifting hook of the crane.

In this embodiment, the four lifting ropes are used to connect the four first lifting lugs 111 with the travelling crane more conveniently.

In an embodiment of the present application, referring to fig. 1, 2 and 5, the inner side of the frame 11 is connected with a reinforcing rib 113.

The reinforcing ribs 113 may be extended along the length direction of the frame 11 such that both ends of the reinforcing ribs 113 are respectively connected to both short sides of the frame 11; the reinforcing ribs 113 may be extended along the width direction of the frame 11 such that both ends of the reinforcing ribs 113 are connected to both long sides of the frame 11, respectively; the reinforcing bars 113 may also be extended in a diagonal direction of the frame 11 such that both ends of the reinforcing bars 113 are connected at both diagonal corners of the frame 11, respectively.

In this embodiment, the reinforcing ribs 113 can strengthen the strength of the frame 11, so as to reduce the risk of deformation and fracture during use, and thus prolong the service life of the frame 11.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
