Description

Technical Field

[0001] The utility model belongs to the technical field of new energy battery replacement, and particularly relates to a hoisting tool for a battery swapping station with an insertion and locking suspension plate. Background Technique

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

[0003] For existing hoisting tools for commercial vehicle battery swapping stations, most of them hook the battery pack through steel wires and traction wheels. For example, the Chinese invention patent with the application number CN202111630812.0 discloses a floating hoisting tool and a battery swapping device. The floating hoisting tool includes: multiple adjusting mechanisms are arranged on the upper tooling, each adjusting mechanism is connected with a steel wire, and the adjusting mechanism is used to adjust the length of the steel wire; each steel wire is respectively connected with the lower tooling, and a grasping mechanism is arranged on the lower tooling; an angle detection device is arranged on the lower tooling, and the angle detection device is used to detect the levelness of the lower tooling and the levelness of the battery to be grasped; the control system is used to control 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 hoisting tool, due to its characteristic of being able to float on the X and Y axes in the horizontal direction, the above-mentioned hoisting tool facilitates the alignment and connection with the battery pack before lifting. However, due to its floating characteristic, when carrying the battery pack, it will continue to shake under the influence of inertia, resulting in its inability to quickly and efficiently complete unloading and replacement. Content of the Utility Model

[0009] A sliding column is fixed on the locking pin, and both ends of the sliding column slide in the directional groove and the guide groove respectively. The setting direction of the directional groove is consistent with the moving direction of the locking pin. The first driving component controls the movement of the moving seat to make one end of the sliding column slide along the guide groove, thereby realizing the sliding of the other end of the sliding column along the directional groove.

[0010] Preferably, both the lowest end and the highest end of the guide groove are straight grooves parallel to the moving direction of the moving seat.

[0011] Preferably, guide grooves are provided in both the directional groove and the guide groove. Bearings are fixed at both ends of the sliding column, and the bearings slide along the guide grooves.

[0012] Preferably, there are two guide sleeves, guide seats and locking pins respectively.

The driving rack is fixedly connected to one moving seat, and the third transmission rack is fixedly connected to the other moving seat;

[0013] The first driving component drives the driving rack to move along the moving direction of the moving seat. The driving rack drives the driving gear to move. The driving gear drives the first transmission rack and the second transmission rack to move in the same direction. The second transmission rack drives the driven gear to move. The driven gear drives the third driven rack to move. By driving the moving seat through the third driven rack, the simultaneous and same-direction movement of the two locking pins is realized.

[0016] Preferably, there is at least one second driving component, and there is at least one supporting plate driven by the second driving component.

[0017] Preferably, there are at least two groups of limiting blocks and unlocking and locking components.

[0018] Advantages of the present utility model: In this solution, the driving component 1 drives the locking pin to insert into the slot on the locking column, enabling a stable connection relationship between the upper suspension plate and the lower suspension plate, achieving relative immobility between the upper suspension plate and the lower suspension plate in the horizontal X-axis and Y-axis directions, and effectively ensuring the stability of the lifting tool during unloading and reloading processes.

[0019] Among them, affected by the structure of the guiding seat, the driving component 1 can be horizontally placed, effectively reducing the space occupied in the vertical direction.
