Abstract

The invention provides an under-beam beam transport lifting appliance system and a lifting method. The under-beam beam transport lifting appliance system comprises a lifting frame, an upper connecting assembly, a lower connecting assembly and a carrying pole beam. The lifting frame is of an equilateral triangle structure, a reinforcing rod is arranged between every two adjacent force transfer rod assemblies, a positioning pin I, a positioning pin II and a positioning pin III are arranged at the three vertexes of the lifting frame, and one vertex is connected with the carrying pole beam. The vertex of the mounting positioning pin I of the lifting frame is connected with one end of the upper connecting assembly, and the other end of the upper connecting assembly can be connected with an under-beam walking mechanism. The vertex of the mounting positioning pin II of the lifting frame is connected with the lower connecting assembly. Compared with a traditional method of transporting beams on a trestle, the method has the advantages that the aim of under-beam beam transport is achieved by using the track of an under-beam maintenance car, the occupied space of the trestle is reduced, the passing efficiency of the trestle is improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a beam lowering beam sling system and a hoisting method, belonging to the technical field of bridge engineering. Background technique [0002] At present, in the transportation of prefabricated beams of cross-river bridges at home and abroad, beam transport vehicles or flatbed vehicles are more commonly used, and the beam erection is completed with lifting devices and bridge erection machines. However, the beam transporting vehicle in this method needs to occupy the trestle or use a barge to carry it, and requires multiple installation, disassembly and turnover of the bridge erecting machine, and the construction efficiency is low. SUMMARY OF THE INVENTION [0003] In order to solve the problems existing in the existing construction process, the purpose of the present invention is to provide a beam transporting sling system and a hoisting method under the beam, which can not occupy the space under the beam (do not affect the ...
