Abstract

The invention discloses a novel jacking system which structurally comprises a supporting seat, sliding rails, transverse guide devices, displacement synchronous supporting seats, jacking oil cylinders, reinforcing steel plates and a horizontal-pushing oil cylinder. By controlling rotating speed of a motor and rotating direction of a shaft, a transmission mechanism can be driven to change moving direction and speed provided by the motor so as to improve forward thrust of a sliding rod to a sliding seat, and moving direction provided by a horizontal-pushing transmission mechanism is changed through a guide mechanism to improve accuracy when an upper transverse moving mechanism and a lower transverse moving mechanism slide on the sliding rails so as to improve quality of engineering construction.

Description

technical field [0001] The invention is a novel walking-type pushing system, which belongs to the field of walking-type pushing equipment. Background technique [0002] At present, the jacking process commonly used in domestic bridge construction is the dragging multi-point continuous jacking method (hereinafter referred to as the dragging method). The moving box girder slides on the temporary pier top or the slideway set on the pier top, and the traction box girder is installed in place. The dragging method is a mature technology in domestic jacking construction, the construction cost is relatively low, and the construction progress is average; this method realizes the translation of the box girder by means of steel strand traction. During the pushing process, a large horizontal force will be generated on the temporary pier or the pier top of the bridge pier, which requires the temporary pier to have a large rigidity, which may cause concrete cracking at the root of the br...
