Description

Technical Field

[0001] The utility model relates to a sub-packaging device for batteries of new energy medium and heavy trucks, belonging to the technical field of sub-packaging batteries of new energy medium and heavy trucks. Background Art

[0002] Currently, new energy vehicles are the development trend for commercial vehicles. Some domestic medium and heavy-duty trucks use new energy batteries. The battery layout can be divided into two types: on both sides of the frame and above the frame. The layout on both sides of the frame can be directly assembled using a crane. For the layout above the frame, the batteries need to be pre-assembled on the battery frame and then assembled to the frame. Currently, when subassembling batteries for new energy medium and heavy-duty trucks, slings are used to lift the batteries to the corresponding height of the battery frame. The operator lifts the batteries and pushes them in from the narrow side of the battery frame. Due to the heavy weight of the batteries, manual lifting is labor-intensive. In addition, the friction between the battery frame and the battery is large. When pushing the batteries into the battery frame, there is great resistance, making it difficult to push and control the direction of the battery push. Multiple adjustments are required, resulting in low work efficiency and poor safety. With the continuous increase in the production of new energy vehicle models, there is an urgent need for specialized tooling for the subassembly of battery packs. Summary of the Invention

[0005] The left pedal and the right pedal are respectively composed of a three-step pedal, a pulley and a locking device.

[0006] The lifting range of the lifting platform can meet the packaging height of the first battery to the fifth battery.

[0007] The left side pedal and the right side pedal are moved by pulleys.

[0008] The left pedal and the right pedal are locked and fixed by a locking device.

[0009] The lifting operation platform of the lifting platform is placed on the narrow side of the battery frame, and the batteries are pushed into the battery frame from the narrow side to complete the sub-packaging.
