When the length of the unit segment 1 changes or the unit segment 1 needs to be removed from between the fixed mounting plate 26 and the movable mounting plate 27 , the movable mounting plate 27 can be moved away from the fixed mounting plate 26 to disengage the unit segment 1 from the movable mounting plate 27 .

[0041] refer to Figure 3 and Figure 4The fixed mounting plate 26 includes a fixed seat 261 and a movable seat 262. The fixed seat 261 is used to be mounted on the base 25.

Since the upper end of the unit segment 1 needs to be welded with a connecting piece, the movable mounting plate 27 is moved upward and rotated to one side to make room for welding the connecting piece at the upper end of the unit segment 1 .

[0043] refer to Figure 6, positioning devices 6 for mounting the unit segment 1 are provided on both the fixed mounting plate 26 and the movable mounting plate 27, and the positioning devices 6 on the fixed mounting plate 26 are located on the fixing seat 261.

[0044] refer to Figure 6 The disk body 61 is provided with four slide grooves 63, the length direction of the slide grooves 63 is projected outward from the center of the disk body 61, and the four slide grooves 63 correspond to the four positioning posts 62 one by one. The disk body 61 is provided with an adjustment device 7, which is connected to the four positioning posts 62 and is used to drive the four positioning posts 62 to move away from or close to the center of the disk body 61 along the direction of the slide grooves 63 at the same time to adapt to different unit sections 1. The adjustment device 7 includes two double-headed screws 71, and a positioning post 62 is respectively installed at both ends of a double-headed screw 71. The thread rotation directions of the two positioning posts 62 and the double-headed screw 71 are opposite.

The driven bevel gear 723 coaxially connected to the driving gear 724 is rotatably mounted on the disc body 61. The other driven bevel gear 723 is coaxially connected to one double-headed screw 71. A driven gear 725 is coaxially fixed on the other double-headed screw 71 without the driven bevel gear 723 installed. The driven gear 725 is meshed with the driving gear 724. The adjustment motor 721 is fixed on the disc body 61. The driving bevel gear 722 is coaxially fixed on the output shaft of the adjustment motor 721. The driving bevel gear 722 is meshed with the two driven bevel gears 723, and the angle between the center line of the driving bevel gear 722 and the center line of the driven bevel gear 723 is 45 degrees, so that the driving bevel gear 722 is meshed with the two driven bevel gears 723 at the same time, and then when the adjustment motor 721 is working, it can drive the two driven bevel gears 723 to rotate at the same time, and one driven bevel gear 723 directly drives one double-headed screw 71 to rotate, and the other driven bevel gear 723 drives the other double-headed screw 71 to rotate through the driving gear 724 and the driven gear 725, so that the two double-headed screws 71 can adjust the positions of the four positioning posts 62 at the same time, thereby ensuring that the distances between the four positioning posts 62 and the center of the disk body 61 are equal.

[0046] The disk body 61 is circular, and the disk body 61 is rotatably connected to the movable mounting disk 27 or the fixed seat 261, and the rotation axis of the disk body 61 is parallel to the direction of the positioning column 62.

When the unit segment 1 is oriented horizontally, the rotation of the disk body 61 can make the unit segment 1 installed between the two positioning devices 6 rotate around the center of the unit segment 1, so that each side of the unit segment 1 is rotated to a position close to the robot 22, thereby facilitating the welding of the unit segment 1.

[0047] refer to Figure 8A bottom plate 81 is fixedly arranged on the fixed seat 261. The bottom plate 81 is located on a side of the fixed seat 261 close to the movable seat 262.
