[0034] Example 1

[0035] When erecting the 400m small-radius curved box girder of a high-speed railway bridge, under the premise of selecting relatively common equipment that only meets the requirements for erecting girders with a curved radius of 500m, the investment cost of specially designed equipment was reduced by using the whole-machine lateral movement device of the bridge erecting machine described in this application. The specific construction method is as follows:

[0036] The following technical solution was adopted for the lateral movement operation of the 400m small radius beam erection construction:

[0037] S1. The bridge erecting machine completed the crossing of the 32m span box girder on a 400m curve with a small radius.

[0038] S2, such as Figure 4 As shown, after the bridge erecting machine passes through the hole, the No. 3 support column 10 retracts by 1.5m and rotates 90 degrees backward. The beam transport vehicle transports the beam to a position 9400mm away from the No. 2 support column at the tail of the bridge erecting machine. At this time, the beam lifting trolley 12 does not install the lifting rod (does not hang the beam).

[0039] S3. The front beam transport vehicle and the rear beam transport vehicle move forward 4.6m simultaneously and then stop. The beam transport vehicle should be protected from slipping.

[0040] S4, such as Figure 5 As shown, the No. 2 support column 9 is moved 328 mm laterally to the inside of the curve by the whole machine lateral movement device (with machine arm 7) of the bridge erecting machine. After the front lifting beam trolley 12 is aligned with the lifting hole at the front end of the beam and the lifting device is installed, the front end of the beam is lifted.

[0041] S5, such as Figure 6 As shown, after the front beam trolley 12 lifts the front end of the beam segment, it moves forward 11.2m synchronously with the rear beam transport vehicle.

[0042] S6. At support column 8, the boom 7 moves 250 mm outward from the curve. Support column 8 is moved 500 mm outward from the curve as a whole via the lateral movement device (with boom 7). At support column 9, the boom 7 moves 300 mm inward from the curve.

[0043] S7, such as Figure 7As shown, after the bridge erecting machine completes the lateral movement of the entire machine, the No. 3 support column 10 rotates 90° and is supported on the beam transport vehicle. After the rear beam lifting trolley 12 moves backward and aligns with the lifting hole at the rear end of the beam to install the lifting device, the rear beam lifting trolley 12 lifts the hook to lift the rear end of the beam.

[0044] S8, such as Figure 8 As shown, the front and rear lifting beam trolleys 12 simultaneously move the lifting beam forward by 24m. After the No. 3 support column 10 retracts and suspends in the air, the No. 1 support column 8 and the No. 2 support column 9 move laterally back to the center position. The front and rear lifting beam trolleys 12 simultaneously lower the beam into place, and the beam erection is completed.

[0045] By installing a lateral movement device on the entire bridge erecting machine, the lateral movement of the entire machine and the individual lateral movement of the outriggers are increased using single-point force, enabling the bridge erecting machine to meet the requirements for outrigger platform erection and beam alignment when crossing a 400m small radius span. Compared to modifying a bridge erecting machine with a 500m curve radius for beam erection, the time for erecting a single beam is reduced by about 1 / 3, allowing for faster completion of the beam erection task.

[0046] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and embodiments shown and described herein.
