Description

Rotatable bridge swivel device Technical Field The invention relates to the field of bridges, in particular to a rotatable bridge swivel device. Background The turning technology is to divide the whole span of the bridge crossing the river or the highway or the railway into two parts, construct the two sides of the two banks or the road respectively, and fold the two parts into an integral bridge by the rotation of the upper beam body of the main pier of the two banks after the upper structure of the bridge is basically completed. For example, patent application number 201010202695.3 discloses a bridge swivel device and a bridge swivel construction method, and specifically discloses that the swivel device comprises a spherical support, a support and a track, wherein the spherical support is arranged at the bottom of one end of a bridge, the support is fixed at one end of the bridge provided with the spherical support, the track is arc-shaped and takes the spherical support as the center of a circle, a flexible cable or a rigid member is pulled between the top end of the support and the bridge, a lifting winch is further arranged, the flexible cable on the lifting winch is connected to the top end of the support, the flexible cable passes through a main sliding positioning piece or a winch which slides along the track on the track and is directly arranged on a main sliding platform on the track, and the bridge swivel device further comprises a swivel driving device for driving the bridge to rotate.
