Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-6, a movable assembling support structure without dismantling a lower beam of a bridge tower comprises a movable rail 10, a movable pulley 20 is placed on the movable rail, a platform beam 40 arranged along the direction of the lower beam is fixed at the top of the movable pulley through a support frame 30, lateral pulleys 410 are fixedly connected to two ends of the platform beam, and stop blocks 110 for preventing the pulleys from falling off are fixed at two ends of the movable rail.
In this embodiment, the support frame includes a vertical steel pipe 310 fixed on the top of the movable pulley, and the upper end of the vertical steel pipe 310 is fixedly connected with the platform beam 40.
In this embodiment, the top of the movable pulley 20 is fixed with a support plate 210, the bottom of the vertical steel pipe is fixed with a flange 311 arranged along the circumferential direction, and the flange and the support plate are provided with mounting holes for passing through locking bolts 312.
The movable pulley 20 and the support plate 210 are fixed by locking bolts 312 passing through the corresponding mounting holes.
In this embodiment, the movable pulley 20 has a limiting hole 201, and a pulley limiting bolt 220 for limiting the movement of the movable pulley can be inserted into the limiting hole.
During installation, the vertical steel pipe 310 and the support plate 210 are fixedly connected through the locking bolt 312, and the matching between the vertical steel pipe and the movable pulley can be removed through the locking bolt when the device is not used.
In this embodiment, the moving rails have a pair, and each moving rail has a pair of moving pulleys 20.
In the embodiment, the pulley limiting bolt 220 is used for limiting, and in practical use, a pulley with a braking structure can be used as the movable pulley 20 or the lateral pulley 410, so that the brake is not performed when the movable pulley needs to be moved, and the position of the whole structure is limited by the brake after the position of the whole structure is determined.
In the second embodiment, in order to improve the stability, the vertical steel pipe 310 is connected with the platform beam through an oblique connecting rod square steel 313.
