Embodiment Construction

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] Such as Figure 1-20The bridge erecting machine of the embodiment includes a main truss 1, the main truss 1 is a truss structure arranged along the bridge direction, and the main truss 1 includes longitudinal beams arranged along the bridge direction and triangular trusses located on the lateral sides of the lower end of the longitudinal beams, two groups The triangular trusses are arranged at intervals along the transverse bridge, leaving gaps in the middle for the crane cables to pass through.

[0047] This embodiment is supported on the bridge deck that has been assembled by a plurality of fulcrums, including the front fulcrum located at the front half of the main truss 1 and the rear fulcrum of the rear half (the front of the present embodiment refers to Figure 11 in the right direction, the rear refers to Figure 11 In ...

Abstract

The invention relates to the technical field of bridge construction, in particular to a bridge erecting machine for fast construction of prefabricated bridges. The bridge erecting machine includes a main truss, a rear fulcrum and a front fulcrum, wherein the main truss is provided with a crane for lifting prefabricated pier columns, prefabricated cover beams and steel main beams; the rear fulcrumcomprises a rear leg arranged at the rear end of the main truss and a middle rear leg positioned in front of the rear leg; the upper end of the middle rear leg is fixed on the main truss, and the lower end is provided with a rolling structure capable of driving the middle and rear leg to travel along the assembled bridge deck; the front fulcrum comprises a front leg and a leveling structure resting on the ground below the front end of the main truss; and the front leg is a vertical support structure whose lower end is supported on the leveling structure, and the upper end of the front leg is fixed on the front end and lower part of the main truss. The bridge erecting machine for fast construction of prefabricated bridges can complete the installation of all components such as the prefabricated pier columns, the prefabricated cover beams, the steel main beams and the like, can realize the simultaneous construction of the upper and lower structures of the bridge, and can effectively improve the construction efficiency of the site.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge erecting machine used for rapid construction of prefabricated bridges. Background technique [0002] In the field of bridge construction, prefabricated bridges can effectively increase the speed of on-site construction, ensure the quality of structural components, improve structural durability, and have broad application scope and prospects. [0003] In the on-site construction of prefabricated bridges, bridge erecting machines are usually used to erect the upper structure, and crawler cranes are used to erect the substructure such as pier columns and cover beams. The construction process requires a lot of manual assistance, and the construction efficiency is low. Traffic has a big impact. The upper structure of the bridge and the lower piers usually need to be constructed twice, which seriously restricts the construction efficiency of the bridge, and the hu...
