Description

Technical Field

[0001] This utility model relates to a hoisting device, and more particularly to an adjustable battery module hoisting device, belonging to the field of battery module hoisting. Background Technology

[0002] Existing battery module hoisting devices are mostly side-pressure hoisting types, which are compact and simple. As energy storage technology moves towards larger capacity, larger modules, and larger cells, and as the number and weight of cells increase, the side-pressure hoisting method becomes problematic due to the weight of the cells themselves. During hoisting, the cells in the module are affected by their own weight. When the adhesion friction between the cells is less than the gravity, the cells may sink, leading to poor welding of the top integrated cover plate, or even the risk of the cells falling off.

[0003] Most existing battery module hoisting devices have relatively fixed side pressure. When the battery cells change due to manufacturing process changes or slight differences in thickness between different batches, the side pressure will change with the differences in the battery cells. This can result in the side pressure being too loose or too tight. If it is too loose, there is a risk of the battery cells sinking or falling. If it is too tight, it will cause damage to the battery cells.

[0004] Therefore, it is necessary to develop a new type of battery module hoisting device to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this invention provides an adjustable battery module hoisting device.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: an adjustable battery module hoisting device, including a device body, the device body comprising: The main frame has a lifting assembly installed in the middle, which is connected to the suction mechanism. The suction mechanism is installed below the main frame and is attached to the battery module. The clamping mechanisms are symmetrically installed on both sides of the suction mechanism. The clamping mechanisms are movably connected to the main frame through the adjustment mechanism. The clamping mechanisms are located on both sides of the battery module and their positions can be adjusted by the adjustment mechanism. Lifting rings installed on the side of the main frame.

[0007] Preferably, the suction mechanism includes a vacuum suction cup connected to the lifting assembly, and the vacuum suction cup is connected to the air passage connector via a connecting pipe.

[0008] Preferably, the lifting assembly includes a guide plate installed in the middle of the main frame and mounting plates symmetrically installed on both sides of the guide plate. A lifting screw is installed in the center of the guide plate, and the output end of the lifting screw is connected to a vacuum suction cup through a central pressure plate.

[0009] Preferably, two guide shafts are spaced apart on the mounting plate, and side pressure plates are symmetrically installed on both sides of the central pressure plate. The ends of the two guide shafts are connected to the vacuum suction cup through the side pressure plates.

[0010] Preferably, the mounting plate has corresponding circular holes, and guide cylinders are installed in each circular hole. The guide shaft passes through the circular hole and can move up and down along the guide cylinder.

[0011] Preferably, the clamping mechanism includes a side pressure plate and a locking lock installed on the inner wall of the side pressure plate. An L-shaped plate is provided on the side of the side pressure plate away from the vacuum suction cup, and multiple reinforcing plates are provided at intervals on the L-shaped plate.

[0012] Preferably, the adjustment mechanism includes push rod clamps symmetrically mounted on the main frame. The push rod clamps are connected to the fixed seat via connecting rods.

[0015] Preferably, support plates are symmetrically arranged on the main frame, with the support plates located on the side close to the side pressure plate, and the push rod clamp is installed in the middle of the support plate.

[0016] This invention proposes an adjustable battery module hoisting device. By employing both side-pressure and top-suction fixing methods, the hoisting process is safe and reliable, eliminating the risk of poor welding of the top integrated cover plate and cell falling due to cell settling.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 An adjustable battery module hoisting device is shown, comprising a device body, the device body including: The main frame 1 has a lifting component 4 installed in the middle, and the lifting component 4 is connected to the suction mechanism. By setting up a lifting component to drive the suction mechanism to move, the suction mechanism generates an adsorption force on the battery module, thereby realizing the hoisting of the battery module. Preferably, the lifting assembly 4 includes a guide plate 41 installed in the middle of the main frame and mounting plates 42 symmetrically installed on both sides of the guide plate. A lifting screw 43 is installed in the center of the guide plate 41, and the output end of the lifting screw 43 is connected to the vacuum suction cup 31 through a central pressure plate 44.

[0023] The guide plate and mounting plate are fixed to the main frame with bolts. The vacuum suction cup is located below the main frame. The top of the vacuum suction cup is equipped with a central pressure plate and a side pressure plate. When it is necessary to lift the battery module, rotate the lifting screw. The lifting screw drives the central pressure plate to move downward, which in turn drives the vacuum suction cup to descend. The guide shaft ensures the descent direction of the vacuum suction cup. When the vacuum suction cup presses down on the top of the battery module, stop rotating the lifting screw and then use the vacuum suction cup to adsorb the battery module. Furthermore, two guide shafts 45 are spaced apart on the mounting plate 42, and side pressure plates 46 are symmetrically installed on both sides of the central pressure plate 44. The ends of the two guide shafts 45 are connected to the vacuum suction cup 31 through the side pressure plates 46.

[0024] Mounting plates are installed on the surface of the main frame, and each mounting plate is equipped with two guide shafts. The guide shafts are used to ensure that the vacuum suction cup descends in a direction perpendicular to the main frame.

[0025] Preferably, the mounting plate 42 has corresponding circular holes, each of which is fitted with a guide cylinder 47. The guide shaft 45 passes through the circular hole and can move up and down along the guide cylinder. By setting the guide cylinder, the direction of movement of the guide shaft is ensured, thereby ensuring the direction of descent of the vacuum suction cup.

[0026] The suction mechanism 3 is installed below the main frame and is attached to the battery module. By installing a suction mechanism below the main frame, the battery module can be attracted and the connection stability of the battery module during hoisting is enhanced.

[0027] The suction mechanism 3 includes a vacuum suction cup 31 connected to the lifting assembly. The vacuum suction cup 31 is connected to the air passage connector via a connecting pipe 32. The vacuum suction cup is a pneumatic vacuum suction cup. The vacuum suction cup is evacuated through the air pipe, and the air in the vacuum suction cup is extracted through the connecting pipe and the air passage connector. Due to the negative pressure generated, the vacuum suction cup firmly holds the top of the battery module.

[0028] The clamping mechanisms 2 are symmetrically installed on both sides of the suction mechanism. The clamping mechanisms 2 are movably connected to the main frame through the adjustment mechanism 5. The clamping mechanisms are located on both sides of the battery module and their positions can be adjusted by the adjustment mechanism. By combining a clamping mechanism with a suction mechanism, the battery module is doubly secured, making the hoisting process safer and more reliable, and avoiding risks such as battery cells falling. An adjustment mechanism moves the clamping mechanism to meet the clamping requirements of different batches of battery cells.

[0029] Specifically, the clamping mechanism 2 includes a side pressure plate 21 and a locking lock 24 installed on the inner wall of the side pressure plate. An L-shaped plate 22 is provided on the side of the side pressure plate 21 away from the vacuum suction cup, and multiple reinforcing plates 23 are provided on the L-shaped plate 22 at intervals.

[0030] By setting side pressure plates, the two sides of the battery module can be clamped. Each side pressure plate has two lifting locking pins on its inner side. The locking pins are used to insert into the positioning holes of the battery module end plate to increase the stability of the connection with the battery module.

[0031] The adjustment mechanism 5 includes push rod clamps 51 symmetrically mounted on the main frame. The push rod clamps 51 are connected to the fixed seat 53 via a connecting rod 52. The fixed seat 53 is mounted on the top of the L-shaped plate 22. The push rod clamps 51 can drive the L-shaped plate to move horizontally. Support plates 14 are symmetrically arranged on the main frame 1. The support plates 14 are located on the side close to the side pressure plate, and the push rod clamps 51 are mounted in the middle of the support plates.

[0032] When the push rod clamp 51 is pushed, the connecting rod 52 drives the fixed seat 53 to move horizontally, which in turn drives the side pressure plate connected to the L-shaped plate to move horizontally. The adjustment mechanism ensures the movement direction and stability of the side pressure plate. In use, the two push rod clamps are pushed towards the center of the main frame. The push rod clamps drive the side pressure plate to move towards the center to clamp the battery module. The side pressure plate presses down on both sides of the battery module, and at the same time, the locking pin is inserted into the positioning hole of the battery module end plate. The stroke of the side pressure plate can be adjusted by setting the push rod clamps, so as to facilitate the adjustment of the side pressure of the battery module.

[0033] To facilitate the movement of the side pressure plates, horizontal sliders 11 are installed at the top corners of the bottom surface of the main frame 1. The top surface of the L-shaped plate 22 is equipped with a locking groove 54 that matches the horizontal slider. The horizontal slider 11 is fitted into the locking groove 54 and can slide horizontally along it. Limiting blocks 12 are provided on the outer side wall of the horizontal slider 11. Figure 2 As shown.

[0034] The main frame is connected to the side pressure plate via a horizontal slider. The horizontal slider has an I-shaped cross-section and is fitted into the locking groove to ensure the stability of the connection between the two. There are two limiting blocks, which are distributed at both ends of the horizontal slider. The limiting blocks are welded to the horizontal slider. The limiting blocks are set to prevent the side pressure plate from moving outward too far and causing it to detach from the locking groove.

[0035] Guide seats 55 are provided on the side of the locking groove 54 away from the center of the main frame. A horizontal slide bar 56 is provided on the guide seat 55. A limiting block 13 is provided on the side wall of the main frame 1. The horizontal slide bar 56 is inserted into the limiting block 13 and can move horizontally along it.

[0036] By setting a limiting block, the maximum distance the side pressure plate can move is limited, thus preventing excessive pressure from damaging the battery module. Four lifting rings 6 are installed on the side of the main frame 1, and the four lifting rings are located on the top surface of the main frame. The lifting rings are the lifting points for the lifting device and the battery module.

[0037] In one embodiment, display modules are also provided at both ends of the main frame. The display modules can display the side pressure of the side pressure plate on the battery module and the suction force of the vacuum suction cup. Based on the real-time monitoring of the display modules, it can be ensured that the side pressure is always kept within a suitable range.

[0038] The usage process of this utility model is as follows: When it is necessary to hoist the battery module, first rotate the lifting screw. The lifting screw drives the central pressure plate to move downward, further driving the vacuum suction cup to descend. The guide shaft ensures the descent direction of the vacuum suction cup. When the vacuum suction cup presses against the top of the battery module, stop rotating the lifting screw. At the same time, perform a vacuuming operation on the vacuum suction cup. Due to the negative pressure generated, the vacuum suction cup firmly sucks the top of the battery module. At this time, push the push rod clamp towards the center of the main frame. It drives the side pressure plates on both sides to clamp the battery module, thus realizing the hoisting of the battery module. Figure 3 As shown.

[0039] Compared with the prior art, the present invention has the following beneficial effects: 1) The module is gripped by two methods: side pressure and top suction. Due to the addition of the top suction cup, after the suction cup presses down on the top of the cell, a vacuum pump is used to evacuate the suction cup, creating a pressure difference with the atmosphere, so that the suction cup firmly holds the top of the cell. Together with the clamping mechanism, it works on the battery module, so that it remains stable during the hoisting process and there is no risk of cell sinking or falling. 2) By adding limit blocks, push rod clamps, and display modules, the side pressure displayed on the display module can be used to determine whether the pressure is appropriate. The side pressure can be adjusted by the push rod clamp to keep it within a suitable range. The limit blocks can limit the clamping force to ensure that the pressure on the battery cell is not too high when the battery module is clamped, so as not to damage the battery cell and affect its electrical performance.

[0040] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
