DETAILED DESCRIPTION

[0020] like Figure 1 、 2 The pole coil liner assembly shown is used for a battery pole coil transport box, and is used for clamping and positioning the battery pole coil unit 3.

[0021] The pole coil lining assembly clamps and positions the battery pole coil unit 3 and then places it into the battery pole coil transport box to transport the battery pole coil.

[0022] In this embodiment, the battery pole coil unit 3 includes a reel and a battery pole coil wound on the reel. Both ends of the reel extend out of the battery pole coil for being mounted between two pole coil liner assemblies.

[0023] In this embodiment, the pole coil liner assembly includes two front and rear liner frames 1 for mounting the battery pole coil unit 3, and a steel inner support frame 2 located at the bottom to position the two front and rear liner frames 1. The steel inner support frame 2 is used to clamp onto the chassis of the battery pole coil transport box, which also includes a box body covering the chassis.

[0024] The two inner liner frames 1 can be installed on the front and rear sides of the steel inner support frame 2 so as to be pluggable and removable up and down, and the two axial ends of the winding shaft of the battery pole winding unit 3 are embedded between the inner liner frames 1 on the front and rear sides.

[0025] Among them, each lining frame 1 includes a lower lining 11 located at the lower part and an upper lining 12 at the lower part which can be plugged and fitted with the upper part of the lower lining 11 for detachable connection. In this embodiment, the upper surface of the lower lining 11 and the lower surface of the upper lining 12 both have positioning grooves and positioning protrusions. When the lower lining 11 and the upper lining 12 are connected, the lower surface of the upper lining 12 is plugged and fitted with the upper surface of the lower lining 11 through the positioning protrusions and positioning grooves.

[0026] A lower card slot 111 opening upward is provided in the middle of the upper surface of the lower lining 11, and an upper card slot 121 opening downward is provided on the lower surface of the upper lining 12. When the lower lining 11 and the upper lining 12 are plugged and connected with each other, a positioning card slot for positioning the shaft end of the reel is formed between the lower card slot 111 and the upper card slot 121.

[0027] In this embodiment, the positioning slot has a slot bottom in the shape of a blind hole, and is used to clamp the shaft end of the winding shaft of the battery pole winding unit 3 .

[0028] In order to ensure that the liner frame 1 can not only play the role of buffering, shock absorption, limiting and stabilizing during transportation, but also sufficiently support the weight of the battery pole coil unit 3. In this embodiment, each liner frame 1 includes a plastic shell made of EPP plastic and a steel support pre-embedded in the EPP plastic shell.

[0029] Specific structure: Figure 3 As shown, each lower liner 11 includes a lower liner plastic shell 112 made of EPP plastic and a load-bearing lower steel support 113 pre-embedded in the lower liner plastic shell 112. The load-bearing lower steel support 113 has a slot bracket located directly below the lower card slot 111. The slot bracket can support the shaft end of the battery pole winding unit 3 and stabilize the groove shape of the lower card slot 111. The insertion rods extending upward from the front and rear corners of the steel inner support frame 2 are respectively inserted and matched with the corresponding load-bearing lower steel support 113.

[0030] like Figure 4 As shown, each upper liner 12 includes an upper liner plastic shell 122 made of EPP plastic and a load-bearing upper steel support 123 pre-embedded in the upper liner plastic shell 122 .

[0031] A locking mechanism 13 is required between the upper and lower liners of each liner frame 1 to stably secure the axial end of the battery pole coil unit 3 within the positioning slot. The stressed lower steel support 113 extends left and right and extends out of the upper portion of the lower liner plastic shell 112 to form two lower locking ears. The stressed upper steel support 123 extends left and right and extends out of the lower portion of the upper liner plastic shell 122 to form two upper locking ears. The locking mechanism 13 is located between the upper locking ear and the corresponding lower locking ear on each side.

[0032] In this embodiment, Figure 1 、 2 As shown, the locking mechanism 13 includes two tensioning rods 131 located on the left and right sides. Each tensioning rod 131 is respectively passed through the upper locking ear and the lower locking ear of the two liner frames 1 in sequence. By setting locking nuts at both ends of the tensioning rod 131, the two tensioning rods 131 are positioned and locked front and back.

[0033] The two tensioning rods 131 not only lock the upper lining 12 and the lower lining 11 of each liner frame 1, but also tighten and lock the left and right sides between the front and rear liner frames 1 by sharing the two tensioning rods 131, thereby preventing the two liner frames 1 from twisting due to force shock during transportation, thereby forming a stable support for the battery pole coil unit 3 clamped in the middle.

[0034] The utility model provides a pole roll lining assembly for a battery pole roll transport box, which secures the reel of the battery pole roll unit between at least two lining frames, and the lining frame is plugged into the steel inner support frame 2 through the load-bearing lower steel support 113, and the steel inner support frame 2 is clamped on the chassis in the battery pole roll transport box. The battery pole roll transport box also includes a box body covering the chassis, so that the lining assembly forms a stable rigid support for the battery pole roll unit 3 clamped in the middle. At the same time, the upper lining plastic shell and the lower lining plastic shell made of plastic have the functions of buffering, shock absorption, limiting and stabilizing the battery pole roll, which can effectively prevent the battery pole roll from being damaged due to bumps, vibrations, shaking, etc. during transportation, thereby ensuring the coil yield, and the components are disassembled and assembled in a snap-fit ​​manner, can be reused, and are green and environmentally friendly.
