Problems solved by technology

The disadvantages of this installation method are: first, to build a construction access road under the bridge, a large amount of land is required; second, special foundation treatment is required for the truck crane operation site to ensure the safety of the hoisting operation; third, the safety and reliability of the large truck crane operation The fourth is that it is greatly affected by the terrain conditions on the site, and it is difficult to implement in complex terrain environments such as water, tidal flats, high piers, and canyons; The impact of weather conditions is greater; Sixth, the comprehensive cost is high

Embodiment 1

[0054] Such as figure 1 Shown is an assembled bridge pier transport frame integrated machine, which includes a pier section transport vehicle 1, a main girder 2 and a pier section hoisting crane 4.

[0055] The pier transport vehicle 1 is a multi-axle tire-type hydraulic transport flat car; it can be designed and manufactured separately, or it can be replaced by a beam transport vehicle for transporting high-speed rail box girders existing in the current construction unit; the main beam 2 is Two and fixedly arranged on the pier section transport vehicle 1 in parallel, the front end of the main girder 2 extends out of the pier section transport vehicle 1 and hangs on the pier section transport vehicle 1, leaving a space between the two main girders 2 There is space for placing pier components to be assembled; the pier section lifting crane 4 can move longitudinally along the track on the top surface of the main girder 2, and the pier section lifting crane 4 is used for lifting ...

Embodiment 2

[0058] Such as Figure 1 to Figure 11 As shown, as a preferred embodiment of the assembled bridge pier transport frame integrated machine, on the basis of Example 1, the main girder 2 includes two fixed main girder sections 5 fixedly installed on the top surface of the pier section transport vehicle 1 and the foldable front cantilever main beam section 7 hinged at the front end of the fixed main beam section 5; The piers transport vehicle 1 is extended, and a main beam support cylinder 6 for supporting with the box girder is arranged at the bottom of the extended position. The tail of the main beam 2 is provided with a balance weight 3 for pressing down the pier transport vehicle 1 .

[0059] Such as figure 1 and figure 2 As shown, the fixed main beam section 5 and the foldable front cantilever main beam section 7 are hinged by a shear pin 9, and the fixed main beam section 5 and the foldable front cantilever main beam section 7 pass through The swing cylinder mechanism 1...

Embodiment 3

[0067] A method for transporting frame of assembled bridge pier based on the integrated machine for transporting frame of assembled bridge pier described in embodiment 1, it comprises the following steps:

[0068] (1) According to the installation sequence of each pier assembly of the assembled pier, each pier assembly is placed on the top surface of the pier section transport vehicle 1 from front to back and fixed; the pier assembly includes a plurality of pier sections 101 and A pier cap 102 .

[0069] (2) The assembled bridge pier transport frame integrated machine travels to the bridge head, extends the main girder support oil cylinder 6 to support the beam end of the box girder that has been erected, and the pier joint hoisting crane 4 lifts the pier joints 101 of the assembled pier in turn , move forward, fall and install to form the pier body of the assembled pier.

[0070] (3) After all the pier body segments are installed, the pier joint hoisting crane 4 lifts, moves...

Abstract

The invention relates to an assembled pier transporting and erecting all-in-one machine and an assembled pier transporting and erecting method based on the same. The transporting and erecting all-in-one machine comprises a pier section transporting vehicle, two main beams and a pier section hoisting crown block, wherein the pier section transporting vehicle is a all-in-one rubber-tyred hydraulic transport flatcar; the two main beams are fixedly arranged on the pier section transporting vehicle in parallel, and the front ends of the main beams extend out of the pier section transporting vehicleand are suspended on the pier section transporting vehicle; a space for placing a pier assembly to be assembled is reserved between the two main beams; the pier section hoisting crown block can longitudinally run and move along a track on the top surface of the main beam and is used for hoisting and lowering the pier assembly to be assembled. The invention further provides an assembled pier transporting and erecting method based on the transporting and erecting all-in-one machine.

Description

technical field [0001] The invention relates to frame transport equipment for prefabricated sections of assembled bridge piers and a frame transport method using the equipment, in particular to an integrated machine for transporting frame piers of assembled type bridges and a method for transporting frame of assembled bridge piers based on the same. Background technique [0002] With the current application of segmental prefabricated assembled piers on the Beijing-Xiong Railway, the use of segmental prefabricated assembled piers will become more and more widespread in the construction of high-speed rail bridges (even highway bridges) in the future. At present, the installation method of this kind of assembled bridge pier is: first, each segment is transported to the site by road respectively, and then installed by a large truck crane. The disadvantages of this installation method are: first, to build a construction access road under the bridge, a large amount of land is requ...
