After the box girder is prefabricated, it needs to be moved out of the girder base to prefabricate the beam of the next hole. The box girder can be moved out of the base by using a beam moving machine, a beam lifting machine, or a beam moving trolley. When using the beam-moving trolley to carry the precast beam bottom mold trolley, it is necessary to use a lateral moving device to move the precast beam bottom mold trolley laterally to different placement points. There is no limit and stable mechanism during lateral transfer, which affects the stable transfer of prefabricated beams

Embodiment Construction
[0028] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0029] see Figure 1-2 As shown, a movable prefabricated beam bottom mold trolley lateral movement device includes two sets of traversing guide rails 1 and a flat carriage arranged side by side. The main beam 2, the lower part of both sides of the square steel main beam 2 are respectively equipped with a driven wheel 4 and a driving wheel 5, and the driven wheel 4 and the driving wheel 5 are all rollingly connected on the traverse guide rail 1, and the square steel main beam 2 is installed There is a driving motor for driv...

The invention discloses a transverse moving device for a movable precast beam bottom mold trolley. The transverse moving device comprises two sets of transverse moving guide rails arranged side by side and a flatcar; the flatcar includes a connecting cross beam; two ends of the connecting cross beam are each fixedly connected with a square steel main beam; a driven wheel and a driving wheel are rotationally installed on lower portions of two sides of each square steel main beam respectively; the driven wheels and the driving wheels are all connected onto the transverse moving guide rails in a rolling manner; a driving motor used for driving the driving wheels to rotate is installed on each square steel main beam; a lifting mechanism is installed in the center position of the upper end of the connecting cross beam; and the connecting cross beam is provided with a service braking mechanism used for limiting rotation of the driven wheels; According to the transverse moving device, the precast beam bottom mold trolley is stably limited during transfer through limiting sleeves and limiting bolts which are in sliding fit; the limiting bolts are inserted into limiting holes of the precast beam bottom mold trolley, and meanwhile reset springs are arranged, and thus, the precast beam bottom mold trolley cannot be jacked up when a limiting bolt does not match the limiting hole, thereby guaranteeing the stability of the precast beam bottom mold trolley during transfer.
Description
technical field [0001] The invention belongs to the technical field of building construction equipment, and in particular relates to a lateral moving device for a movable prefabricated beam bottom mold trolley. Background technique [0002] Simply supported box girders for high-speed railways are large in size, self-heavy, high in quality requirements, and difficult in construction technology. The manufacturing method must be prefabricated by setting up girder yards on site. Therefore, a large number of box girder prefabrication yards are set up on the high-speed railway construction site to prefabricate the bottom of the girder. Mold processing. After the box girder is prefabricated, it needs to be moved out of the girder base to prefabricate the beam of the next hole. The box girder can be moved out of the base by using a beam moving machine, a beam lifting machine, or a beam moving trolley. When using the beam-moving trolley to carry the precast beam bottom mold trolley,...
