Special hoisting system for 900-ton transporting and erecting all-in-one machine

Abstract

A special hoisting system for a 900-ton transporting and erecting all-in-one machine comprises a plurality of gantry cranes, the gantry cranes are arranged on two sides of a track bridge under construction in a striding mode, the hoisting system further comprises a hoisting adjusting unit and a positioning supporting unit, the top of the hoisting adjusting unit is connected with a crane of the gantry cranes, and the bottom of the hoisting unit is connected with a bridge erecting machine in a hoisting and hanging mode. And the positioning and supporting unit is fixedly arranged on a top surfaceof a beam box built at a previous stage and provides positioning and supporting for rear supporting legs of the bridge erecting machine. According to the hoisting system, a problem that the all-in-one machine is constrained and limited by environmental conditions in a hoisting process can be solved, the 900-ton transporting and erecting all-in-one machine can normally feed beams and accurately hoist and locate the beams, bridge climbing and beam erecting and transporting construction is facilitated, the construction problems of beam feeding and beam erecting and transporting under complex working conditions are effectively solved, the structure is simple, operation is easy, a beam loading period is remarkably shortened, and wide economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, and relates to a special hoisting system for a 900-ton frame-transporting integrated machine. Background technique [0002] When the high-speed railway passenger dedicated line uses 900 tons of all-in-one machine equipment for transporting and erecting girders, it is usually necessary to set up a ramp at the beam lifting station, and then the all-in-one machine will use the ramp to transport and erect the beams on the bridge after loading the beams in the beam storage area. However, with the rapid development of high-speed passenger dedicated lines, the geographical environment such as hills, mountains, and rivers has changed greatly, and the geological conditions are complex and changeable. It is difficult to transport the equipment to the designated construction site, and the construction is extremely difficult. In addition, when the girders are transported, the construction of the ...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a special hoisting system for a 900-ton all-in-one machine. The all-in-one machine for transporting and erecting the beam normally feeds the beam and accurately lifts and positions it, which is convenient for the construction of the upper bridge transporting the erecting beam, effectively solving the construction problems of feeding and transporting the erected beam under complex working conditions, and has a simple structure and simple operation, and significantly reduces the beam installation period. Has a wide range of economic benefits
