Description

Technical Field

[0001] The utility model relates to the technical field of battery modules, in particular to a hanger for single-row modules. Background Art

[0002] Most electric vehicles use lithium-ion batteries, but a single battery cannot meet the power demand of electric vehicles. It is often necessary to connect multiple batteries in series or in parallel to increase the battery capacity. In actual production, in order to ensure the reliability of production and the convenience of processing and maintenance, multiple batteries are usually combined into a power battery module, and then multiple battery modules are assembled into a battery pack in a battery box. The battery pack supplies power to the electric vehicle to meet the power demand of the electric vehicle. After the existing batteries are formed into a single-row module, they need to be transferred to the next station for multi-row grouping. Because the batteries are pasted together, manual transportation is inconvenient, and the single-row module is easily deformed during the handling process, resulting in poor battery module size. For this reason, we propose a hoist for single-row modules. Utility Model Content

[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] like Figure 1-3 As shown, the utility model is a hanger for a single-row module, comprising a mounting frame 1, guide sleeves 2 are arranged on both sides below the mounting frame 1, the two guide sleeves 2 are centrally symmetrical, a movable rod 3 is inserted in the middle of one end away from each other, the movable rod 3 is movably connected to the guide sleeve 2, the movable rod 3 can be extended and retracted inside the guide sleeve 2, the movable rod 3 and the guide sleeve 2 are movably connected through a first hydraulic cylinder 4, the two ends of the first hydraulic cylinder 4 are movably connected to the movable rod 3 and the guide sleeve 2 through a U-shaped seat respectively, when the first hydraulic cylinder 4 is extended and retracted, the first hydraulic cylinder 4 can drive the movable rod 3 to move in the horizontal direction, the movable rod 3 is fixedly connected to an L-shaped fixed plate 5 below the side away from the mounting frame 1, a mounting plate 6 is arranged on the upper end of the L-shaped fixed plate 5, a second hydraulic cylinder 7 is arranged in the middle above the mounting plate 6, the stroke end of the second hydraulic cylinder 7 passes through the mounting plate 6 and is fixedly connected to the connecting plate 8, a through groove 9 is provided in the middle of the upper end of the L-shaped fixed plate 5, and the connecting plate 8 One side of the through slot 9 is fixedly connected with the pressure plate 10, and the connecting plate 8 is movably connected with the L-shaped fixed plate 5. When the second hydraulic cylinder 7 is working, the second hydraulic cylinder 7 pushes the connecting plate 8 to move in the vertical direction, and the pressing plate 10 is also moved by the transmission of the connecting plate 8. Two first guide rods 11 are inserted at the lower end of the L-shaped fixed plate 5. The first guide rod 11 is fixedly connected with the clamping plate 12 near one side of the mounting frame 1. The first guide rod 11 is located between the clamping plate 12 and the L-shaped fixed plate 5 and is sleeved with a spring 13. The first guide rod 11 is movably connected with the L-shaped fixed plate 5. When the first hydraulic cylinder 4 drives the two movable rods 3 to approach each other, the two L-shaped fixed plates 5 are also approached to each other through the transmission of the movable rod 3. When the L-shaped fixed plate 5 moves, the two clamping plates 12 can clamp the single-row module when the first guide rod 11 is transmitted. When the clamping plate 12 clamps the single-row module, the spring 13 is compressed, so that the pressure on the single-row module can be buffered by the elastic force of the spring 13.

[0021] The mounting plate 6 is located on both sides of the second hydraulic cylinder 7 and is plugged with a second guide rod 14. The second guide rod 14 is fixedly connected to the connecting plate 8 at the bottom, and the second guide rod 14 is movably connected to the mounting plate 6.

[0024] Lifting ears 17 are provided on both sides of the upper side of the mounting frame 1. The provision of the lifting ears 17 makes it easier for workers to lift the single-row modules using a lifting device.

[0025] Specifically, in the utility model, when the single-row module is lifted, the first hydraulic cylinder 4 drives the movable rod 3 to move in the horizontal direction, so that the two movable rods 3 are close to each other, and the two L-shaped fixed plates 5 are also close to each other through the transmission of the movable rod 3. When the L-shaped fixed plate 5 moves, the two clamping plates 12 can clamp the single-row module through the transmission of the first guide rod 11.
