Specifically, in order to enable the roller 3 to strictly roll along the preset route, a temporary track can be laid on the ground, and a power device is installed on the roller 3 to better control the rolling of the roller 3, so as to better control the angle between two adjacent guide rails 1.

2) The uppermost curved glass piece 19 to be mounted is mounted on the uppermost set of clamping devices between the adjacent guide rails 1. The clamping device comprises a supporting plate 5 extending along the axial direction of the guide rail 1, one side of the supporting plate 5 is fixedly connected with the inner wall of the guide rail 1, the other side of the supporting plate 5 is connected with a supporting plate 6 in a sliding fit mode, the supporting plate 6 is perpendicular to the supporting plate 5, sliding grooves 9 are formed in two opposite sides of the supporting plate 5, and two ends, close to one side of the supporting plate 5, of the supporting plate 6 extend towards the sliding grooves 9 to form sliding blocks 10 in a sliding fit mode with the sliding grooves 9. The drive motor 4 is mounted on the support plate 6. A strip-shaped tooth 7 is arranged on one side of the supporting plate 5 connected with the bearing plate 6 along the extending direction of the supporting plate, and a gear 8 meshed with the strip-shaped tooth 7 is arranged on a driving shaft of the driving motor 4; the bearing plate 6 is also provided with a claw for clamping the arc glass 19, and when the driving motor 4 drives the gear 8 to rotate, the claw can drive the arc glass 19 to move to the installation position along the guide rail 1 under the action of the counter force of the strip-shaped teeth 7. The jack catch includes a sliding block 11, and this sliding block 11 one end is connected with bearing board 6, and the other end passes the guide slot and articulates at this end and is equipped with a clamping part, the pivot of clamping part is parallel with the axis of sliding block 11, the clamping part is used for centre gripping arc glass 19.
