Description

Bracket supporting structure of through-type bridge fabrication machine

Technical Field

The utility model relates to a building engineering technical field, concretely relates to bracket bearing structure of through type bridge fabrication machine.

Background

At present, in the erection of a concrete continuous beam bridge, beam block segments are usually prefabricated in a beam yard, transported to a bridge site on the ground, and then assembled into the bridge on site, so that a bridge erecting machine is an essential engineering machine in bridge erection.

The bridge girder erection machine is equipment capable of placing prefabricated beam pieces on a prefabricated bridge pier. Bridge girder erection machines belong to the crane category, as their main function is to lift the beam piece up and then transport it into position and put it down. The bridge erecting machine is different from a common crane in a large sense, the required conditions are harsh, and the bridge erecting machine runs on a beam piece or moves longitudinally. The bridge girder erection machine is divided into a highway bridge erection machine, a conventional railway bridge erection machine, a passenger-dedicated railway bridge erection machine and the like. Bridge girder erection machines are classified into the following types: 1. the single beam bridge girder erection machine has a box beam as the suspension arm, which is suspended forwards and has a foldable upright column at the front end. The front upright post can be driven into the bridge position under the no-load state by self, and then the front upright post is straightened and supported on the front bridge pier. When the beam piece (or the whole beam) moves along the suspension arm, the suspension arm is close to the state of the simply supported beam. When the bridge is built, the machine can automatically drive into the bridge position under the no-load state, the beam piece is firstly transferred from the railway flat car to the special beam transporting car by using the special gantry crane, then the beam transporting car and the rear end of the bridge building machine are aligned, and the beam piece is hoisted by using two beam hoisting trolleys running on the suspension arm of the bridge building machine, and moves forward along the suspension arm to reach the bridge position to drop the beam. The machine has the advantages that: the balance weight is cancelled, the locomotive is not required to be pushed, the bridge head and the crossing line are not required for beam feeding, the degree of mechanization is improved, and the safety performance is improved to some extent. 2. A double-beam bridge girder erection machine is characterized in that a suspension arm consists of a left box girder and a right box girder, and the two girders penetrate through a machine body and extend out to the front end and the rear end. The two ends are respectively provided with a folding upright post consisting of two leg rods. The front end and the rear end of the bridge girder erection machine can be used for hanging and dropping the girder; when the direction of the frame beam is changed, the turning is not needed; in order to adapt to the curved frame beam, the front arm and the rear arm can swing in a horizontal plane; when the split erection is carried out, the beam can be in place without moving the beam or shifting the track. 3. The double-cantilever type bridge girder erection machine cannot be driven by a locomotive and needs to be pushed. The front arm is used for hanging the beam, the rear arm is used for hanging the balance weight, and the front arm and the rear arm can not swing in the horizontal plane. After the bridge girder is hoisted by the bridge girder erection machine, the axle load is increased, and a newly-built embankment at the bridge head is softer, so that a reinforcing measure must be taken for a bridge girder hoisting travelling section of the bridge girder erection machine.

The existing bridge girder erection machine is provided with a plurality of supporting columns and supporting legs, the supporting columns and the supporting legs are matched to alternately operate when being erected and passing through holes, a plurality of section beams are mutually assembled in the operation process of the bridge girder erection machine, the strength requirement of the supporting legs is high due to too large self weight of the bridge girder erection machine, even the assembling process cannot be met, and in the application process of the supporting leg structure, the supporting leg structure needs to be prefabricated according to the size of a pier firstly and then is assembled, and the construction period is long. Further optimizing the structural design of the supporting upright posts undoubtedly has important significance for optimizing the assembly process and shortening the construction period.
