Abstract

The invention discloses a novel bridge swivel construction device based on a rack track traction system, which is based on a spherical hinge for bridge swivel construction, a gear device is designed at the outer edge of a turntable, and a traction cable in common swivel construction is combined with a gear. The device is suitable for bridge swivel construction under various conditions, the swivel speed can be accurately controlled through the fixed rotating angle of the single gear after transformation, and construction safety is guaranteed while construction precision is improved. In addition to the advantages, the device also overcomes the defect of one-way traction, if the rotation angle exceeds the limit, the gear applies force in the opposite direction, and the maneuverability in the construction process is optimized.

Description

technical field [0001] The invention relates to the technical field of bridge swivel construction, in particular to a novel bridge swivel construction device based on a rack and track traction system. Specifically, a swivel construction device is designed with the outer edge of the turntable pulling the cableway and the pulling cable in the shape of a gear, and the device can be applied to the swivel construction of various bridges. Background technique [0002] As my country's railway and highway networks have gradually taken shape, there are more and more bridge construction projects spanning existing lines. It is the key research object of this kind of bridge engineering to ensure the safety and reliability of the engineering construction without affecting the operating conditions of highways and railways. Therefore, the research on the key technologies of the design and construction of bridges spanning existing lines is the current research topic of bridge construction t...
