[0002] A lifting tool refers to a device for lifting heavy objects in a lifting machine. The most commonly used lifting tools for lifting finished products are hooks and slings. Others include lifting rings, lifting suction cups, tongs, and forklift forks, etc.

[0003] For existing lifting tools of commercial vehicle power exchange stations, most of them realize the hooking of battery packs through steel wires and traction wheels. For example, the Chinese invention patent with the application number 202111630812.0 discloses a floating lifting tool and a power exchange device. The floating lifting tool includes: a plurality of adjusting mechanisms are arranged on the upper tooling, each adjusting mechanism is connected with a steel wire, and the adjusting mechanism is used for adjusting the length of the steel wire; each steel wire is respectively connected with the lower tooling, and a grabbing mechanism is arranged on the lower tooling; an angle detection device is arranged on the lower tooling, and the angle detection device is used for detecting the levelness of the lower tooling and the levelness of the battery to be grabbed; the control system is used for controlling the adjusting mechanism to synchronously or independently adjust the length of each steel wire according to the levelness data detected by the angle detection device, so as to adjust the inclination direction and levelness of the lower tooling and the battery.

[0004] As a typical chain-type lifting tool, the chain-type lifting tool is convenient for aligning and connecting with the battery pack before lifting due to its characteristic of being able to float in the X and Y axes of the horizontal direction. However, also affected by its floating characteristic, when carrying the battery pack, it will continuously shake under the influence of inertia, resulting in its inability to quickly and efficiently complete unloading and replacement. Summary of the Utility Model

In this embodiment, two locking columns 3 are provided, and two driving components one 5 are provided and respectively control one locking head 4 to tightly press against one locking column 3 to achieve the stability of the connection between the upper suspension plate 1 and the lower suspension plate 2. In other embodiments, one driving component can also drive two locking heads 4 to tightly press against two locking columns 3, or one driving component one 5 can drive a group of locking heads 4 to tightly press against the locking columns 3. Each group of locking heads 4 includes at least two, and each locking head 4 tightly presses against one locking column 3; in addition, in other embodiments, one locking column 3 is provided, and at least one driving component one 5 is provided. The driving component one 5 drives at least two locking heads 4 to tightly press against the locking column 3.

[0027] Among them, refer to Figure 2, the locking structure further includes a guide rail 6 on which the locking head 4 slides. A locking groove capable of allowing the locking post 3 to enter is formed on the locking head 4. The locking groove is used to restrict the movement of the locking post 3 in the horizontal X-axis and Y-axis directions. At the same time, the opening of the locking groove is flared to facilitate the entry of the locking post 3.

[0028] Among them, refer to Figure 3 , Figure 4 , Figure 5 , among which, at least a set of limiting blocks 7 for restricting the movement of the battery pack in the horizontal single-axis direction are provided on the bottom surface of the lower suspension plate 2. An unlocking and locking assembly 8 capable of supporting the battery pack is also provided on the lower suspension plate 2. In this embodiment, three limiting blocks 7 are provided, realizing the limitation of the battery pack in the horizontal Y-axis direction and the one-way limitation in the X-axis direction;

[0029] Among them, the unlocking and locking assembly 8 includes a second driving assembly 81 and a support plate 82. The second driving assembly 81 drives the support plate 82 to extend into or out of the lower part of the battery pack. At least one second driving assembly 81 is provided, and at least one support plate 82 driven by the second driving assembly 81 is provided.

[0030] Working process and principle:

[0031] When using the lifting tool in this solution, the lifting tool is transported to the designated position through a conveying device such as an overhead rail. At this time, the locking head 4 and the locking post 3 are in a disengaged state, and floating can occur between the upper suspension plate 1 and the lower suspension plate 2. Adjust the position so that the battery pack enters the space surrounded by the three limiting blocks 7. Subsequently, the unlocking and locking assembly 8 controls the support plate 82 to extend into the bottom surface of the battery pack, and the battery pack can be supported during the lifting process of the lifting tool. At the same time, after the battery pack is supported, the locking head 4 can be controlled by the first driving assembly 55 to press against the locking post 3. After being pressed tightly, the relative static state of the upper suspension plate 11 and the lower suspension plate 22 in the horizontal X-axis and Y-axis directions can be achieved. Of course, under the action of the frictional force between the locking head 4 and the locking post 3, the relative static state of the upper suspension plate 11 and the lower suspension plate 22 in the Z-axis direction can also be achieved.

[0032] The above are only embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
