[0017] The utility model discloses a cooperation of support spare, support spare is fixed on the upper chord, and the middle back plate and frame body are arranged on the support spare, and the middle back plate covers on the frame body. By screwing adjusting nut, with the position of support spare in height direction can be adjusted, by the cooperation of first waist -shaped hole and second waist -shaped hole, with the position of frame body relative to support spare in front -back direction and left -right direction can be adjusted. The combination of above-mentioned mode, with the position of middle back plate in height direction, front -back direction and left -right direction can be adjusted, effectively satisfy the assembly demand of middle back plate, and the practicality is strong.

[0018] As Figs. 1-2 It is the middle back plate fixed assembly of an automatic escalator described in this embodiment, and the middle back plate fixed assembly is installed on the truss of escalator. The middle back plate fixed assembly includes support spare 2, frame body 4, middle back plate 6 and fastening assembly 5. Among them, support spare 2 includes top plate 21 and screw rod 22. One end of screw rod 22 and the end face of top plate 21 abut, and are welded with each other, to form integral structure. Several groups of support spare 2 are distributed on the upper chord 1 of the truss of escalator. Among them, several assembly holes are processed on the preset position on the upper chord 1. Screw rod 22 of support spare 2 is movably inserted on the upper chord 1 through the assembly hole. The adjusting nut 3 is threadedly connected on the upper and lower sides of screw rod 22 on the upper chord 1. By screwing the adjusting nut 3 on the upper and lower sides, the up-down position of screw rod 22 on the upper chord 1 can be adjusted, and screw rod 22 is locked and fixed on the upper chord 1. When screw rod 22 is assembled to the upper chord 1, top plate 21 is horizontally arranged above the upper chord 1.

[0019] The frame body 4 is welded by several frame edges, and the frame edges of the frame body 4 are overlapped on the top plate 21 of each group of support members 2. Among the frame body 4 and the top plate 21, one is processed with a first waist-shaped hole 41 extending along the left-right direction, and the other is processed with a second waist-shaped hole 211 extending along the front-rear direction corresponding to the first waist-shaped hole 41. In the embodiment, the first waist-shaped hole 41 is formed on the frame edge of the frame body 4, and the second waist-shaped hole 211 is located on the top plate 21. The fastening assembly 5 is inserted into the first waist-shaped hole 41 and the second waist-shaped hole 211 corresponding to the first waist-shaped hole 41. The fastening assembly 5 has a locking state of locking the frame body 4 and the top plate 21 with each other, and a loosening state of allowing the frame body 4 and the top plate 21 to move relative to each other. Through the above structure design, when the fastening assembly 5 is in the loosening state, the front-rear position and the left-right position of the frame body 4 relative to the top plate 21 can be adjusted, and when the fastening assembly 5 is in the locking state, the frame body 4 and the top plate 21 are locked with each other. The middle back plate 6 is covered on the frame body 4 by screw connection. When the frame body 4 moves, the middle back plate 6 moves along with it. The fastening assembly 5 includes a screw and a locking nut matched with the screw.

[0020] During assembly, the screw rod 22 of the support member 2 is inserted into the assembly hole on the top chord 1 of the truss. The assembly hole can be drilled on site or pre-processed. Then, the screw rod 22 is locked on the top chord 1 by adjusting the nut 3 to fix the support member 2. The frame body 4 is placed on the top plate 21 of the support member 2, the screw is inserted into the corresponding first waist-shaped hole 41 and second waist-shaped hole 211, and is locked by the locking nut to fix the frame body 4 and the top plate 21. After the frame body 4 is fixed, the middle back plate 6 is fixed on the frame body 4. When the position of the middle back plate 6 needs to be adjusted, the adjusting nut 3 is screwed to adjust the position of the support member 2 in the height direction, thereby moving the frame body 4 and the middle back plate 6 as a whole to adjust the position of the middle back plate 6 in the height direction. Loosen the fastening assembly 5 and move the frame body 4 in the front-rear direction and the left-right direction, and then lock the fastening assembly 5 to adjust the position of the frame body 4 relative to the support member 2 in the front-rear direction and the left-right direction. In the above manner, the position of the middle back plate 6 in the height direction, the front-rear direction and the left-right direction can be adjusted, which effectively meets the assembly requirements of the middle back plate 6 and has strong practicability.

[0021] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process transformation according to the content of the present application, or direct or indirect application in other related technical fields, is also included in the patent protection range of the present application.
