Simple prefabricated bridge deck plate hoisting trolley and using method thereof

Abstract

The invention discloses a simple prefabricated bridge deck plate hoisting trolley and a using method thereof. The hoisting trolley comprises stand columns, a cross beam, truss longitudinal beams and asteel wire rope, wherein the four stand columns are vertically and symmetrically distributed on the two sides, the truss longitudinal beams are correspondingly fixed between the two stand columns oneach side through flange bolts, a horizontal first cross beam and a horizontal second cross beam are arranged at the two ends of the truss longitudinal beam on each side, chord members are further fixedly arranged at one ends of the stand columns, two spaced third cross beams are arranged between every two adjacent chord members, and hangers used for lifting the prefabricated bridge deck plate isarranged on the third cross beams; one end of the steel wire rope is correspondingly fixed on the chord members of the truss longitudinal beams, and the other end of the steel wire rope is fixed on the top of the stand columns; and a trolley traveling mechanism is arranged at the bottom of each stand column. The hoisting trolley is assembled on a bridge construction site, and the installation of the prefabricated bridge deck plate is completed; and the hoisting trolley is simple in structure, low in cost, high in construction efficiency and convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of highway and railway bridge construction, in particular to a simple prefabricated bridge deck hoisting trolley and a using method thereof. Background technique [0002] With the development of my country's economy, the process of infrastructure construction has been accelerated. In order to make people travel more convenient, more and more bridges have been built in various cities. Because the structure of the tied arch bridge is relatively simple, the construction difficulty is relatively small, and the construction period is relatively short, so it has been widely used in bridge construction. [0003] The upper structure of some tied arch bridges is arch ribs, suspenders, tie rods, beams, longitudinal beams and bridge decks, wherein the tie rods are arranged horizontally along the bridge driving direction, the beams are supported on the tie rods and are perpendicular to the tie rods, and the longitudinal...

AI Technical Summary

Problems solved by technology

[0004] For the hoisting of the prefabricated bridge deck, if the bridge is under the busy railway line, the crane cannot be parked under the bridge; when the bridge is under the water surface of the river, it is very difficult to hoist the bridge deck into place from under the bridge using the hoisting equipment on the hull Because the bridge deck is difficult to pass between the longitudinal and horizontal girders, and because of the large width of the bridge, it is also difficult to lift the bridge deck from the side under the bridge to the middle of the bridge

Existing methods often use large-scale hoisting equipment such as tower cranes or cable cranes for installation, but the cost of large-scale hoisting equipment is high, the construction efficiency is low, and the installation quality is not high; this situation urgently needs a simple and effective bridge deck hoisting method and corresponding construction equipment
