[0023] Specifically, a top groove 4 is provided on the top extension direction of the aluminum alloy rail upper half 1 and the aluminum alloy rail 2, a lower clamping plate 5 is provided in the top groove 4, and an upper clamping plate 6 is provided above the top groove 4. The threaded ends of the upper clamping plate 6 and the lower clamping plate 5, and multiple clamping plate bolts 7 pass through the upper clamping plate 6 and are connected to the lower clamping plate 5 through threads. By tightening each clamping plate bolt 7, the upper clamping plate 6 and the lower clamping plate 5 are jointly clamped and fixed to the aluminum alloy rail 2 and the aluminum alloy rail upper half 1.

[0024] The outer wall of the aluminum alloy track lower half 3 is fixed to the maintenance door sealing plate 8. Specifically, the fixing structure includes four through-holes in the center of the maintenance door sealing plate 8, which form a row of holes. Multiple sealing plate bolts 12 penetrate the row of holes and the outer wall of the aluminum alloy track lower half 3 and then threadably connect to the long strip plate 13. The long strip plate 13 is located in the interlayer of the aluminum alloy track lower half 3. The upper portion of the maintenance door sealing plate 8 is detachably connected to the side wall of the aluminum alloy track upper half 1, and the end of the maintenance door sealing plate 8 is detachably connected to the aluminum alloy track 2.

[0025] In order to facilitate the positioning and installation of the maintenance door sealing plate 8, limit plates 9 are clamped at both ends of the maintenance door sealing plate 8. The limit plates 9 are connected to the side walls of the aluminum alloy rail 2 and the upper half of the aluminum alloy rail 1. The inner side of the limit plate 9 is provided with a limit clamping groove 901 that cooperates with the end of the maintenance door sealing plate 8.

[0026] Grooves 10 are formed on the side walls of the aluminum alloy track 2 , the aluminum alloy track upper half 1 and the aluminum alloy track lower half 3 , and the maintenance door sealing plate 8 and the limit plate 9 are fixed in the grooves 10 by a plurality of clips 11 .

[0027] Specifically, the side wall of the aluminum alloy rail 2 is provided with two grooves 10 along the length direction, and the side wall of the aluminum alloy rail upper half 1 and the side wall of the aluminum alloy rail lower half 3 are respectively provided with a groove 10 along the length direction.

[0028] The upper portion of the limit plate 9 is fixed to the groove 10 on the upper side wall of the aluminum alloy track 2 via a clamp 11. One end of the upper portion of the limit plate 9 extends to the side wall of the aluminum alloy track upper half 1 and is fixed to the groove 10 on the aluminum alloy track upper half 1 via a clamp 11. The lower portion of the limit plate 9 is fixed to the groove 10 on the lower side wall of the aluminum alloy track 2 via a clamp 11.

[0029] The upper part of the maintenance door sealing plate 8 is clamped with the groove 10 on the side wall of the upper half of the aluminum alloy track 1 through the clamping piece 11, the middle part of the lower side of the maintenance door sealing plate 8 is clamped with the groove 10 on the lower half of the aluminum alloy track 3 through the clamping piece 11, and the lower end of the maintenance door sealing plate 8 is clamped with the groove 10 on the lower part of the side wall of the aluminum alloy track 2 through the clamping piece 11.
