Detailed Description

The utility model will be described in further detail with reference to the drawings and the detailed description.

The energy storage battery pack lifting device shown in fig. 1 comprises a lifting frame 1, wherein a main lifting ring 4 is arranged at the upper end of the center of the lifting frame 1, the lifting frame 1 is connected with a main lifting rope through the main lifting ring 4, and secondary lifting rings 5 are arranged at four end points of the lifting frame 1. Specifically, as shown in fig. 2, the hoisting frame 1 comprises a frame main body 101, a main hoisting ring 4 with a ring opening at the upper end is arranged at the center of the frame main body 101, four suspension arms 102 are connected to the frame main body 101, the four suspension arms 102 are distributed around the frame main body in an X shape by taking the frame main body as the center, the four suspension arms 102 and the frame main body 101 are integrally formed, and a secondary hoisting ring 5 with a ring opening at the lower end is arranged at the tail end of the four suspension arms 102. A side plate structure is connected with the secondary suspension ring 5 at the tail end of the suspension arm and is connected with the suspension hook assembly 3 through a lifting rope 8.

In this embodiment, the side plate structure shown in fig. 2 includes a ladder-shaped side plate 2, and two side plate fixing blocks 6 are symmetrically disposed on both sides of the short side of the top. The lifting rope hanging holes 9 distributed in a multi-group array mode are formed in the horizontal direction of the long edge of the bottom of the side plate 2, and the flexible adaptation of lifting interval parameters is achieved by adjusting the connection positions of lifting ropes 8 and the lifting rope hanging holes 9, so that the appearance matching requirements of battery packs with different specifications are met. The flexibility of this design allows for adjustment to different hoisting requirements.

Further, the side plate 2 is fixedly connected with the side plate fixing block 6 by bolts. The arc-shaped end of the side plate fixing block 6 is also provided with an orifice for installing a lifting shackle 10, and the side plate structure is installed into the secondary lifting ring 5 through the lifting shackle 10 so as to be connected with the lifting frame 1. The side plate structure has the function of prolonging the distance between the two lifting hooks, so that the distance between the two lifting arm endpoints of the lifting frame is not limited. The design improves the operation flexibility of the lifting device and reduces the possibility that the lifting device is required to be replaced because the size specification of the lifting frame and the lifting object are seriously different. Meanwhile, in the hoisting operation process, the side plate structure can play a certain role in intercepting the battery pack, so that the swinging degree of the battery pack in the hoisting operation process is effectively slowed down. The interception function further improves the stability and safety of the whole hoisting device, and ensures the safe operation of hoisting operation.

The hook assembly 3 shown in fig. 3 includes a hook body 31. The hook body 31 is shown in FIG. 4, in the form ofThe lifting hook is of a shape structure, the top end of the lifting hook is of a larger thickness, an aperture for installing the lifting ring 7 is formed in the lifting hook, the lifting ring 7 is used for being connected with the lifting rope 8, a bottom opening 33 is formed in the bottom end of the lifting hook, an intermediate plate 32 is extended between grooves of the lifting hook main body, and two bolt through holes 11 are formed in the intermediate plate 32.

Preferably, the hook assembly 3 is further provided with a spring clamping plate device comprising a spring clamping plate 12, the spring clamping plate 12 being placed in parallel between the intermediate plate 32 and the bottom end of the hook body, and two bolts 15 being inserted into the bolt through holes 11 of the intermediate plate 32 and fixedly connected to the spring clamping plate 12. The caliber of the bolt through hole 11 is larger than that of the bolt 13, the bolt 13 and the spring clamping plate 12 are in threaded connection, the bolt is a movable bolt for the lifting hook main body (or the middle plate) and can move up and down in the lifting hook groove, and the middle plate only plays a role in limiting the movement of the bolt and the spring clamping plate.

Further, a spring 14 is arranged between the spring clamping plate 14 and the middle plate 32, and the spring 14 is sleeved on a bolt 13 in threaded connection with the spring clamping plate 12. One end of the spring 14 abuts against the lower end surface of the intermediate plate 32, and the other end abuts against the upper end surface of the spring clamping plate 12. Under the stress-free state, the spring clamping plate device gradually approaches the bottom end of the lifting hook main body under the action of elastic potential energy of the spring 14, namely the spring clamping plate 12 and the bolt 13 in threaded connection with the spring clamping plate move downwards under the action of the spring 14 until the nut of the bolt 13 abuts against the middle plate 32.

The specific use method of the lifting hook assembly 3 is that an operator presses the spring clamping plate 12 of the lifting hook assembly upwards, the spring 14 is compressed, a concave space is formed between the spring clamping plate 12 and the bottom end of the lifting hook main body, the concave space is connected into the bottom supporting tray of the energy storage battery plate in a concave mode, and the spring clamping plate 12 is loosened. The spring clamp plate 12 will move towards the bottom under the force of the spring 14 until the hook assembly 3 clamps the battery pack support tray.

Preferably, the bottom opening at the bottom end of the hook body may be snapped into a protruding point of the support tray, or a latch, knot, or the like may be used to secure the hook to the support tray.

In the traditional energy storage battery pack hoisting device, a plurality of operators are required to lift a lifting hook in the hoisting operation process of the energy storage battery pack until a hoisting rope connected with the energy storage battery pack is in a tight state, and in the hoisting operation process, the operators face risks of clamping injury and the like, and the hoisting operation efficiency is low due to the fact that more operators and inconvenience in coordination are caused.

Compared with the traditional energy storage battery pack hoisting device, the hoisting device is provided with the spring clamping plate structure, only one operator needs to install four hoisting hooks in turn, the hoisting hooks automatically clamp the hoisted object through the spring clamping plate structure, the hoisting device is more stable than a hook type hoisting hook and more convenient than a bolt type hoisting hook, meanwhile, the hoisting device is further provided with the side plate structure, and the possibility of falling of the hoisted object is reduced due to the interception effect of the side plate on the swing of the hoisted object.

In summary, the side plate structure is added to the hoisting frame, and the design of adding the spring clamping plate to the lifting hook effectively solves the problems of the traditional energy storage battery pack hoisting device in the aspects of labor cost, safety, efficiency and the like, and provides a high-efficiency, convenient and safe energy storage battery pack hoisting solution.
