Swivel bridge equipment
The invention provides swivel bridge equipment which comprises a traction cable guiding device, at least two sets of traction cables and a concrete rotary disc used for bearing a swivel bridge. The concrete rotary disc is of a reinforced concrete structure, the embedded sections of the traction cables are pre-buried in the concrete rotary disc, and the wire outlet sections of the traction cables are wound in the circumferential direction of the concrete rotary disc. The traction cable guiding device comprises a force bearing plate, the force bearing plate is arranged at the wire outlet positions of the traction cables and comprises an embedded part and an extending part which are connected with each other; the embedded part is embedded in the concrete rotary disc, and the extending part islocated on the outer surface of the concrete rotary disc and extends in the circumferential direction of the concrete rotary disc. The wire outlet section, located at the wire outlet position, of each traction cable abuts against the surface of the side, away from the axis of the concrete rotary disc, of the force bearing plate. The swivel bridge equipment can provide support for the traction cables in the radial direction of the concrete rotary disc, the pressure intensity generated by the traction cables on concrete in the bridge swivel construction process is reduced, and concrete crushingand traction cable damage are prevented.
本发明提供一种转体桥梁设备，包括牵引索导向装置、至少两组牵引索、以及用于承载转体桥梁的混凝土转盘，混凝土转盘为钢筋混凝土结构，牵引索的埋入段预埋于混凝土转盘内，牵引索的出线段沿混凝土转盘的周向绕设，牵引索导向装置包括承力板，承力板设置于牵引索的出线位置处，承力板包括相互连接的埋设部和伸出部，埋设部埋设于混凝土转盘内，伸出部位于混凝土转盘外表面且沿混凝土转盘的周向延伸，牵引索位于出线位置处的出线段抵靠于承力板远离混凝土转盘轴线一侧的表面。本发明所涉及的转体桥梁设备能够对牵引索提供沿混凝土转盘的径向的支撑，减小了桥梁转体施工过程中牵引索对混凝土产生的压强，防止混凝土压溃以及牵引索受到损伤。
