The invention discloses a rotary rod type multidirectional displacement bridge expansion device. The device comprises a rotating rod, a rotating shaft, edge beam steel, movable middle beam steel, fixed middle beam steel and a joist, wherein the rotating rod rotates along the rotating shaft, a limiting rod installed at the top of the joist is driven to move in a long-strip-shaped through hole formed in the rotary rod, therefore, a distance between a first displacement box and a second displacement box is adjusted, adjustment of the gap width between the edge beam steel and the movable middle beam steel and the gap width between the movable middle beam steel and the fixed middle beam steel are further realized, butt joints are few in the adjusting process of the joint width between the edgebeam steel and the movable middle beam steel and between the movable middle beam steel and the fixed middle beam steel, the balance of the joint width between the edge beam steel and the movable middle beam steel and the joint width between the movable middle beam steel and the fixed middle beam steel is guaranteed, the device is of a steel structure and is not prone to aging and corrosion, and the service life of the device is prolonged.
本发明公开了一种旋杆式多向变位桥梁伸缩装置，包括旋杆、转动轴、边梁钢、移动中梁钢、固定中梁钢和托梁，通过利用旋杆沿转动轴转动，从而带动托梁顶部安装的限位杆在旋杆上开设的长条形通孔上移动，从而实现对第一位移箱和第二位移箱之间距离的调节，进一步实现了对边梁钢与移动中梁钢和移动中梁钢与固定中梁钢之间缝宽的调节，边梁钢与移动中梁钢和移动中梁钢与固定中梁钢之间缝宽调节过程中对接缝较少，保证了边梁钢与移动中梁钢和移动中梁钢与固定中梁钢之间缝宽的均衡性，装置均采用钢结构不易老化、腐蚀，延长了装置的使用寿命。
