Specific implementation manners

[0016] To describe in detail the technical content, achieved purpose and effect of the present invention, the following is described in conjunction with the implementation manners and with reference to the accompanying drawings.

[0017] Please refer to Figures 1 to 11 As shown, a lifting device for an energy storage battery cell module of the present invention includes: A support plate 1, symmetrically provided with two or more levels of first battery cell specification marks 11 from the middle to both ends in the length direction, and the support plate 1 is provided with first positioning holes 12 corresponding to the first battery cell specification marks 11; A first lifting tool 2, slidably arranged along the length direction of the support plate 1 and locked with the first positioning holes 12; A support bar 3, the two ends of which in the length direction are respectively connected to the two first lifting tools 2 on both sides of the support plate 1, the support bar 3 is symmetrically provided with two or more levels of second battery cell specification marks 31 from the middle to both ends in the length direction, and the support bar 3 is provided with second positioning holes 32 corresponding to the second battery cell specification marks 31; A second lifting tool 4, slidably arranged along the length direction of the support bar 3 and locked with the second positioning holes 32.

[0018] As can be seen from the above description, the beneficial effects of the present invention are as follows: for the hoisting device of the energy storage battery cell module, on the surface of the support plate 1, there are silk prints of marks corresponding to different specifications of battery cells for different lengths of modules at the positions of the first positioning holes 12 on both sides. For example, at the position of the module length of the 280 / 314 battery cell module 1P8S, there are silk prints of marks of different battery cells (such as 280 / 314 / 100Ah) at the second positioning holes 32 in the width direction of the corresponding end plate on the surface of the support bar 3, enabling the production line workers to quickly identify and adjust the positioning of the first hoist 2 and the second hoist 4, greatly improving the production efficiency. Through the above design structure, the quick adjustment of the hoisting dimensions of different battery cell modules can be achieved without disassembly, replacement, or locking and fixing, greatly improving the production efficiency. At the same time, it realizes multi-purpose use of one machine, improving the production efficiency and reducing the management and maintenance costs of hoisting tools while saving costs.

[0019] In an alternative embodiment, the first hoist 2 includes a slider 21 and a first fastener 22. The slider 21 is slidably connected to the support plate 1. Both ends of the support bar 3 are connected to the slider 21, and the slider 21 is locked to the first positioning hole 12 through the first fastener 22.

[0020] In an alternative embodiment, the first hoist 2 further includes an upper sling ring 23, an iron ring 24, and a lower sling ring 25. The slider 21 is connected to the support bar 3 through the upper sling ring 23, the iron ring 24, and the lower sling ring 25 in sequence.

[0021] As can be seen from the above description, there are two upper and lower sling rings provided on both the left and right sides of the slider 21, and iron rings 24 are fixed on the sling rings. The iron rings 24 can move freely within the sling rings, thereby realizing flexible connection. The flexible structure of the sling rings in cooperation with the iron rings 24 can achieve flexible hoisting cooperation between the hook and the hoisting hole of the module end plate, reducing the cooperation error tolerance and improving the practicality of the hoisting tool.

[0022] In an alternative embodiment, both the slider 21 and the support bar 3 are provided with screw holes 33, and the upper sling ring 23 and the lower sling ring 25 are respectively screwed to the corresponding screw holes 33.

[0023] As can be seen from the above description, the lower surface of the slider 21 is provided with a screw hole 33 for fixing with the screw rod of the upper sling ring 23, thereby fixing the sling ring on the slider 21. The lower sling ring 25 is locked and fixed to the screw hole 33 on the upper surface of the support bar 3 through threaded connection.

[0024] In an alternative embodiment, the second sling 4 is locked to the second positioning hole 32 through the second fastener 41. Both the support plate 1 and the support bar 3 include a profile body 34. The first fastener 22 and the second fastener 41 both include a spring 42, a thimble 43, a gland 44 and a pull ring 45. The spring 42 is fixed to the profile body 34 through the gland 44. One end of the thimble 43 is embedded in the first positioning hole 12 or the second positioning hole 32 under the support of the spring 42, and the other end of the thimble 43 is connected to the pull ring 45.

[0025] As can be seen from the above description, the structure of the pull ring 45 cooperating with the thimble 43 realizes quick positioning and installation, and can meet the installation and positioning requirements without debugging with other installation tools.

[0026] During installation, first install the thimble 43 on the profile body 34, then install the spring 42, and finally fix the gland 44 at the end through a threaded structure to fix the head end of the thimble 43 in the hole groove structure. The pull ring 45 is locked to the thimble 43 through a threaded structure at the other end of the thimble 43, so that when the worker pulls the pull ring 45, the thimble 43 can compress the spring 42 to realize the telescopic function. In the natural state, the thimble 43 passes through the side wall of the slider 21 and is in clearance fit with the positioning holes on both sides of the support plate 1 to realize the positioning function. When the position needs to be adjusted, the pull rings 45 can be pulled out on both sides at the same time, so as to drive the thimble 43 to make the thimble 43 withdraw from the hole positions on both sides of the support plate 1. At this time, the slider 21 can be moved and the position can be adjusted. Releasing the pull ring 45 can realize the hole and pin fit again under the action of the spring 42 to realize the positioning function. Similarly, the second fastener 41 is installed and adjusted.

[0027] In an alternative embodiment, the second sling 4 includes a suspension rod 46. One end of the suspension rod 46 is provided with a socket 461 that is inserted and cooperated with the profile body 34 of the support bar 3, and the other end of the suspension rod 46 is provided with a module hook 462.

[0028] As can be seen from the above description, the structure of the socket 461 in the shape of a "mouth" on the suspension rod 46 is used to penetrate and cooperate with the support bar 3 with a clearance to realize the linear sliding of the hook on the support bar 3. During the process of forming different battery cells into groups, it is necessary to compress the length dimension of the battery cells. Therefore, end plates are used on both the left and right sides of the battery cells. The compression device applies force to the large surface of the end plates to realize the compression of the length dimension of the battery cell groups. Therefore, the end plates play an important role in the forming process. In order to transport the formed battery cell modules, a lifting hole 51 is often provided on the end plate. Therefore, this invention patent exactly uses the lifting hole 51 on the module to cooperate with the module hook 462 on the lifting device to realize the overall lifting and transportation of the module.

[0029] In an alternative embodiment, both the first positioning hole 12 and the second positioning hole 32 are provided with chamfers 121 for inserting the thimble 43.

[0030] As can be seen from the above description, the chamfer 121 structure of the positioning hole cooperates with the silk screen marking on the product to achieve the quick centering and positioning of the ejector pin 43, thereby improving the production efficiency.

[0031] In an alternative embodiment, both ends of the slider 21 are provided with clamping grooves 211 that are respectively slidably connected to two side edges of the support plate 1.

[0032] As can be seen from the above description, the support plate 1 and the clamping groove 211 of the slider 21 on the lifting assembly are in clearance fit, enabling the slider 21 to linearly move on the support plate 1.
