Longitudinally-moving and transversely-moving flatcar system

Abstract

The invention discloses a longitudinally-moving and transversely-moving flatcar system. The longitudinally-moving and transversely-moving flatcar system comprises a longitudinal walking unit (1) and further comprises a transverse walking unit (2). The longitudinal walking unit (1) comprises a first walking flatcar (3). A flatcar table (4) is arranged on the first walking flatcar (3). A front flatcar (5) is arranged on the flatcar table (4). The transverse walking unit (2) comprises a second walking flatcar (6). The height of the second walking flatcar (6) is equal to the sum of the height of the flatcar table (4) and the height of the first walking flatcar (3). A first guide rail (7) is arranged on the flatcar table (4). A second guide rail (8) is arranged on the second walking flatcar (6). The first guide rail (7) and the second guide rail (8) are of the same structure. By means of the longitudinally-moving and transversely-moving flatcar system, overall beam loading can be conducted at preset transverse moving positions on the ground, and the longitudinally-moving and transversely-moving flatcar system is convenient to operate, easy to move, stable to move, safe and high in work efficiency.

Description

technical field [0001] The invention relates to a vertical and horizontal moving flat car system for a bridge, in particular to a vertical and horizontal moving flat car system for transporting large steel components on a bridge. Background technique [0002] In the construction of long-span bridges, the entire box girder needs to be transported to the bridge deck for beam loading operations before the bridge can be constructed. The whole box girder is very heavy, some even weigh tens of tons, and it is very inconvenient to transport the whole box girder. At present, the transportation of the whole box girder mainly uses a leveling vehicle to move longitudinally to the preset position, and then move it to the preset position by a crane and other equipment. The overall box girder is lifted to a high altitude, and then transported horizontally to the bridge deck for girder installation. That is to say, when operating in this way, the whole box girder needs to be moved lateral...

Problems solved by technology

The whole box girder is very heavy, some even weigh tens of tons, and it is very inconvenient to transport the whole box girder. At present, the transportation of the whole box girder mainly uses a leveling vehicle to move longitudinally to the preset position, and then move it to the preset position by a crane and other equipment. The overall box girder is lifted to the height, and then transported horizontally to the bridge surface for girder installation

That is to say, when operating in this way, the whole box girder needs to be moved laterally to the bridge deck through the crane equipment, but when the whole beam is moved laterally through the crane and other equipment, the operation is very inconvenient because the crane and other equipment are relatively large, and the horizontal It is not safe to move, and sometimes, the overall installation beam may fall on the processed bridge deck due to the weak connection, damaging the processed bridge deck, resulting in low work efficiency due to re-construction, and when the existing equipment moves laterally , requiring more labor
