Description

[0001] The invention relates to the technical field of prefabrication of box girders, in particular to an automated side forming device for the prefabricated box girder.

[0002] Box girders are one of the most important construction methods for highway and railway bridges in China. The earliest construction method was cast-in-place concrete, which involves long construction periods, significant traffic impacts, high overall energy consumption, large on-site personnel, and high labor intensity. Later, the concept of prefabricated bridge construction emerged, in which box girders are prefabricated in a standardized central prefabrication facility, constructed simultaneously with the bridge substructure, and then transported to the designated site by truck and assembled with the assistance of bridge engineers.

[0003] The prefabrication of box girders for high-speed railway is a systematic and complex project with high requirements, diverse processes and high professionalism, resulting in problems such as high labor cost, low construction efficiency and difficult management. With the improvement of HSR box girder prefabrication process and the application of mechanical automation tools, HSR box girder prefabrication will be gradually processed, especially the research and application of HSR box girder prefabrication production line construction process, which will effectively solve the disadvantages of the traditional prefabrication method and promote HSR box girder prefabrication towards automated construction and industrialization.

Demolding the side mold and precisely closing the mold is a repetitive work on the production line. Replacing manual labor with automation or semi-automation can effectively reduce construction labor costs while improving the standardization level of box girder prefabrication.

[0019] In the description of the present invention, the terms "top", "bottom", "left", "right", "front", "rear", etc., indicate orientations or positional relationships based on those illustrated in the accompanying figures and are used solely to facilitate and simplify the description of the invention. They are not intended to suggest or imply that the device or element referred to must have a particular orientation, be constructed, and function in a particular orientation, and are therefore not to be construed as limiting the present invention.

[0020] An automated side forming device for the box girders of the high-speed railway, as shown in the Fig. 1 and Fig. 2 shown ( Fig. 2 is rotated 90° to the left for clarity), which comprises a side mold mechanism 2, a support cross member 4, a side mold support mechanism 3 and a lifting mechanism 5, of which: a side mold mechanism 2, wherein a side mold flange plate part and a side mold web part are connected to each other, simply see the existing design of the side mold mechanism; a support cross member 4, which are symmetrically arranged on two outer sides of the bottom of the side mold mechanism 2, concretely speaking, the side mold mechanism consists of two symmetrical sets of side mold flange sections and side mold web sections, with a set of support cross members 4 on the outer side of each set of side mold flange sections and side mold web sections;a side mold support mechanism 3, provided in a plurality of groups at longitudinal intervals on both outer sides of the side mold mechanism, each group of the side mold support mechanism comprising at least two length-adjustable side mold spacers, one end of which supports a corresponding portion of the side mold flange portion or the portion of the side mold web portion, and the other end of which is connected to the support cross member 4, a plurality of side mold support mechanisms 3 on the same side together support a set of side mold flange portions and side mold web portions, meanwhile, by adjusting the length of the adjustable spacer, fine adjustment of the side mold flange and the side mold web during molding together and pre-adjustment during demolding can be achieved;The lifting mechanism 5, which is arranged longitudinally in multiple groups below the support beam 4, can be lifted at the upper end to be connected to the support beam 4.
