[0002] Urban bridges are often accompanied by complex terrain conditions such as crossing pipelines, waters and underground spaces during construction. Steel structure jacking technology has been widely used in steel structure bridge construction in recent years due to its advantages such as fast construction speed, high installation accuracy, low operating cost and strong crossing capacity.

The walking jacking method has high requirements for the synchronization accuracy of hydraulic and electrical control. However, its synchronization may not meet the ideal requirements in actual use. In addition, during the jacking construction of steel box girders, the beam body will have a lateral deviation in the left and right directions during the longitudinal movement. Once the lateral deviation is too large, it will cause deviation from the jacking line, the beam body will become unstable or damaged due to excessive force, difficult to slide or stuck, etc., and even after the beam body is pushed into place, the deviation between the center line of the beam and the center line of the line will exceed the standard, resulting in unqualified beam erection.

According to the angle between the bottom surface and the side surface of the steel box girder 17, the cross plate 14 is pulled upward, and the cross plate 14 drives the limit plate 15 to slide inside the extrusion plate 12 and compress the spring. The spring generates elastic force, and at the same time, the cross plate 14 drives the clamping rod 16, and the clamping rod 16 slides out from the inside of the clamping hole, and the adjusting bolt 13 is turned, and the adjusting bolt 13 is screwed to drive The extrusion plate 12 moves laterally inside the installation groove, and the extrusion plate 12 squeezes the movable plate 11, so that the movable plate 11 rotates through the torsion spring shaft, and the angle between the movable plate 11 and the top of the second adjustment seat 10 is adjusted.

The steel box girder 17 moves, and the lifting cylinder 9 drives the second adjusting seat 10 to descend and separate from the steel box girder 17. The longitudinal cylinder 4 and the first adjusting seat 6 drive the adjusting plate 8 and the lifting cylinder 9 and the second adjusting seat 10 to move in the opposite direction. Repeating the above operation facilitates the walking-type pushing movement of the steel box girder 17. The steel box girder 17 can be laterally adjusted and corrected by the correcting cylinder 7, the adjusting plate 8, the lifting cylinder 9, the second adjusting seat 10 and the movable plate 11 to ensure that the moving route of the steel box girder 17 is consistent with the pushing route, which is highly practical.
