Expansion joint device of railway continuous bridge
The invention provides an expansion joint device of a railway continuous bridge, and belongs to the technical field of railway bridges. Beam end telescopic devices and steel rail telescopic adjusters are arranged between the middle transition beam and the main bridge end and between the middle transition beam and the approach bridge end respectively. A piston rod on the first side of the first double-outlet-rod piston cylinder is connected with the main bridge end, a cylinder barrel of the first double-outlet-rod piston cylinder is connected with the middle transition beam on the second side, a piston rod on the first side of the second double-outlet-rod piston cylinder is connected with the middle transition beam, and a cylinder barrel of the second double-outlet-rod piston cylinder is connected with the approach bridge end on the second side. An oil cavity, on the first side, of the first double-outlet-rod piston cylinder is communicated with an oil cavity, on the second side, of the second double-outlet-rod piston cylinder, and an oil cavity, on the second side, of the first double-outlet-rod piston cylinder is communicated with an oil cavity, on the first side, of the second double-outlet-rod piston cylinder. The displacement of the middle transition beam is half of the displacement of the main bridge end all the time, so that the main bridge end has an ultra-large expansion amount which is twice the expansion amount of the middle transition beam relative to the approach bridge end.
本发明提供了一种铁路连续桥梁的伸缩缝装置，属于铁路桥梁技术领域。中间过渡梁与主桥端之间、中间过渡梁与引桥端之间分别设置有梁端伸缩装置及钢轨伸缩调节器；第一双出杆活塞缸于第一侧的活塞杆与主桥端连接，第一双出杆活塞缸的缸筒于第二侧与中间过渡梁连接，第二双出杆活塞缸于第一侧的活塞杆与中间过渡梁连接，第二双出杆活塞缸的缸筒于第二侧与引桥端连接，第一双出杆活塞缸于第一侧的油腔与第二双出杆活塞杆于第二侧的油腔连通，第一双出杆活塞缸于第二侧的油腔与第二双出杆活塞缸于第一侧的油腔连通。实现中间过渡梁的位移始终是主桥端位移的一半，使主桥端相对于引桥端具有两倍于中间过渡梁伸缩量的超大伸缩量。
