Description

Technical Field

[0001] This utility model relates to the field of new energy commercial vehicle technology, and in particular to a self-clamping flexible lifting device for power batteries of new energy commercial vehicles. Background Technology

[0002] Because the entire power system of new energy electric commercial vehicles consists of power batteries and motors, traditional assembly processes cannot meet the characteristics of existing products. In particular, the lack of specialized lifting equipment during the assembly, disassembly, repair, and replacement of power batteries leads to extremely low work efficiency, severely impacting work pace and production capacity. Since a single power battery module weighs over 200 kg, lifting equipment is essential for its assembly, disassembly, replacement, and repair. Because most lifting equipment is motor-driven, significant swaying occurs during lifting and stopping, potentially causing the load to slip and fall, posing a significant safety risk.

[0021] like Figure 1-6 As shown, a self-clamping flexible lifting device for power batteries of new energy commercial vehicles includes a clamping mechanism, a parallelogram linkage mechanism, a pushing mechanism, and an adjusting mechanism.

[0022] A parallelogram linkage mechanism is connected to a clamping mechanism, which includes two clamping plates 1. A pushing mechanism is provided between the tops of the two clamping plates 1, and an adjusting mechanism is provided between the bottoms of the two clamping plates 1. The adjusting mechanism is an end effector 9, which includes a pin 91 and a wing nut 93. Slotted holes 92 are provided on the left and right sides of the bottom of the clamping plates 1, and the pin 91 slides through the slotted holes 92 and is screwed to the wing nut 93. Preferably, the plane containing the slotted holes 92 is marked with length scale lines. The slotted holes 92, pins 91, and wing nuts 93 are used in combination. The end of the pin 91 has a large chamfer to facilitate insertion into the pre-reserved lifting holes in the power battery module frame. The wing nut 93 is a standard part, facilitating manual tightening or loosening to adjust the distance between the two end effectors 9 on the same side. By adjusting the installation position of the end effectors 9, different specifications (i.e., different length specifications of power batteries) of power batteries can be lifted, reducing labor intensity and improving production efficiency.

[0023] Furthermore, the strip-shaped sliding hole 92 has an elongated stepped hole structure, and the pin 91 has a stepped flange shaft structure. This stepped fit structure prevents slippage and detachment.

[0024] The driving mechanism is a cylinder 4; preferably, the cylinder 4 is a commonly used cylinder piston rod, compressed air pipe 5, and air inlet 8, and the air source acts on the cylinder piston rod through the air inlet 8 and compressed air pipe 5.

[0025] It also includes a cylinder controller 6; a cylinder controller 6 is provided on the top of a clamping plate 1, and the cylinder 4 is controlled by the cylinder controller 6. The cylinder controller 6 is provided with several control function buttons 7. The control function buttons 7 can be divided into opening, retraction, micro-motion and locking functions, which meet the requirements of the application scenario of this utility model.

[0026] The parallelogram linkage mechanism includes two first links 2 and two second links 3. The first ends of the two first links 2 are hinged together, and the second ends of the two first links 2 are respectively hinged to the first ends of the two second links 3. The two second links 3 are cross-hinged at the middle, and the second ends of the two second links 3 are respectively connected to the tops of the two clamping plates 1. When the second ends of the two second links 3 are respectively hinged to the tops of the two clamping plates 1, it can adapt to power battery specifications of different widths. When the second ends of the two second links 3 are respectively fixed to the tops of the two clamping plates 1, it can adapt to power battery specifications of the same width.

[0027] It also includes a lifting ring 10; the lifting ring 10 is located at the hinge of the first end of the two first connecting rods 2. The lifting ring 10 is used for lifting equipment.
