Prefabricated slab type damping track structure for track traffic turnout
The invention relates to the technical field of rail traffic, in particular to a rail traffic turnout prefabricated plate type damping rail structure which comprises a steel rail body, a sleeper body below the steel rail body and a groove. When the rail traffic turnout prefabricated plate type damping rail structure is used, a train firstly passes through the upper portion of an air bag and then passes through the upper portion of the sleeper body; at the moment, the steel rail body extrudes the air bag firstly, so that air in the air bag enters the hollow plate through the air inlet pipe, air in the hollow plate and the multiple buffer grooves is supplemented, and if the air pressure in the buffer grooves and the hollow plate is enough, the air in the air bag can be exhausted through the multiple air overflow holes in the outer side of the air overflow pipe; when the steel rail body extrudes the bearing plate, the bearing plate can downwards extrude the buffer plates through the buffer rods, so that the buffer plates slide in the buffer grooves, gas in the hollow plate and the buffer grooves cannot be exhausted, gas in the hollow plate and the buffer grooves is compressed, and the train damping effect is achieved.
本发明涉及轨道交通技术领域，具体为一种轨道交通道岔预制板式减震轨道结构，包括钢轨本体及其下方的枕木本体，还包括有凹槽，此轨道交通道岔预制板式减震轨道结构，在使用时，列车会先经过气囊上方，而后再经过枕木本体上方，此时钢轨本体则会先对气囊进行挤压，使得气囊内的气体通过进气管进入空心板内，从而使空心板及多个缓冲槽内的气体得到补充，若缓冲槽及空心板内的气压足够，则气囊内的气体会通过溢气管外侧的多个溢气孔排出，当钢轨本体对承重板进行挤压时，承重板会通过多个缓冲杆向下挤压缓冲板，使多个缓冲板滑动在缓冲槽内，由于空心板及缓冲槽内的气体无法被排除，从而导致其内部的气体被压缩，达到对列车减震的作用。
