Track seam connecting device and including this track seam connecting device's track

The utility model relates to a track traffic technical field, concretely relates to track seam connecting device, wherein, track seam connecting device is including setting up in the first buttcover plate and the second buttcover plate of two adjacent track tip respectively, and the portable connecting plate that sets up between first buttcover plate and second buttcover plate abutting end, when first buttcover plate, the second buttcover plate is along orbital length direction in opposite directions or during adversive movement, the length direction motion of first buttcover plate and secondbuttcover plate abutting end can be followed to the connecting plate. This technical scheme is through setting up mobilizable connecting plate between first buttcover plate and second buttcover plateabutting end, the train crosses from the connecting plate during gap between through first buttcover plate and second buttcover plate abutting end to reduce gap between first buttcover plate and the second buttcover plate abut
