Problems solved by technology
Since 2020, with the gradual introduction of the third-generation high-speed rail equipment into the market, the first-generation high-speed rail equipment will be idled or scrapped in large quantities. If the supporting use of alternate generations is not considered, and the universality problem is not solved, the first-generation equipment will inevitably be left idle. and waste of resources

The invention relates to an alternate high-speed rail equipment matching girder erection method, which comprises the following steps that a high-position bridge girder erection machine is subjected to lowering transformation, so that the minimum girder outlet height of the high-position bridge girder erection machine is smaller than the maximum girder feeding height of an ultra-low-position girder transporting vehicle; the ultra-low-position beam transporting vehicle carries the beam piece to a bridge head to be aligned with the high-position bridge erecting machine and is connected with a synchronous power supply; and the high-position bridge girder erection machine discharges the girder pieces of the ultra-low-position girder transporting vehicle, and then the girders fall to complete girder piece laying. In the invention, the transformation of a high-position bridge girder erection machine in first-generation high-speed rail equipment is concentrated on an inverted T-shaped beam at a front supporting leg and an O-shaped beam at a rear supporting leg, and the height reduction of the front supporting leg and the rear supporting leg is realized by segmenting and replacing structural parts of the inverted T-shaped beam and the O-shaped beam; other parts of the main body structure of the high-position bridge girder erection machine are not changed, so that the transformation workload is small, and the utilization efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of bridge laying on high-speed railway lines, in particular to a method for erecting girders supporting high-speed railway equipment with alternate generations. Background technique [0002] Since the development of the first generation of high-speed rail equipment in China in 2006, the high-speed rail equipment has been updated and developed from the first generation to the third generation in just 15 years. Significant progress has been made in all aspects. [0003] The first generation of high-speed rail equipment is mainly used for bridge construction in plain areas. The height of the whole machine is high, and it is a high-level equipment in terms of structure. The second-generation high-speed rail equipment is mainly used for the erection of bridges and tunnels in mountainous areas, including all-in-one machine for transporting frames, low-level beam transporting vehicles, etc., and is used for the co...
