Abstract

The invention provides a height-adjustable bridge pier hoisting machine, a construction method and an overpass passing method. The height-adjustable bridge pier hoisting machine comprises a frame beamassembly including a cross beam, a hoisting mechanism arranged on the frame beam assembly and used for hoisting a prefabricated pier to be assembled and a supporting leg assembly used for supportingthe frame beam assembly; and the supporting leg assembly comprises splitting parts and support leg parts, the upper ends of the splitting parts are connected with the cross beam and penetrate throughthe end part of the cross beam, the lower ends of the splitting parts are detachably connected with the support leg parts, and the cross beam is suitable for moving on the splitting parts and the support leg parts. According to the height-adjustable bridge pier hoisting machine, the construction method and the overpass passing method, by arranging the supporting leg assembly with the splitting part and the support leg part, the height of the hoisting machine can be adjusted, and the convenience of transportation of the hoisting machine when the hoisting machine passes through height-limited terrains such as bridge holes of an overpass is improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated bridge pier installation equipment, in particular to a height-adjustable bridge pier hoisting machine, a construction method and a method for crossing an overpass. Background technique [0002] At present, the height of hoisting machines used to hoist bridge piers is generally high and fixed. When the hoisting machine encounters an overpass during transportation, the hoisting machine must be disassembled and transported through special tools, which makes the transportation cost of the hoisting machine and The difficulty of transportation has greatly increased. Contents of the invention [0003] The problem to be solved by the invention is: how to improve the convenience of transporting the pier hoisting machine when passing through the height-limited terrain such as the bridge opening of the overpass. [0004] In order to solve the above problems, the present invention provides a height-a...
