Abstract

A rack rail connecting system for a ballastless track of a large-gradient simply-supported bridge is used for keeping the pitch of racks on the ballastless track fixed when a bridge floor of the simply-supported bridge stretches out and draws back, so that the running stability and safety of a train on the bridge are guaranteed. The two ends of each beam body are supported on the top ends of the two adjacent bridge piers, the gradient low end and the gradient high end of each beam body are the beam body fixed end and the beam body non-fixed end respectively, and the track plates are correspondingly arranged on the top faces of the beam bodies and connected into a whole. The telescopic beam is installed on the track plate through a telescopic buckle plate, the track plate is provided with a transverse restraining structure for limiting transverse displacement of the telescopic beam, the telescopic buckle plate vertically restrains the telescopic beam, and the end, on the beam body fixing end side, of the telescopic beam is fixedly connected with the track plate through a telescopic beam buckle plate. The telescopic beam can longitudinally stretch towards the non-fixed end of the beam body relative to the track plate. The racks are fixedly installed on the top faces of the telescopic beams through rack rail fasteners, and the steel rails are fixedly installed on the top faces of the two transverse sides of the track plate through steel rail fasteners.

Description

technical field [0001] The invention belongs to the technical field of mountain rack traffic, and in particular relates to a ballastless track rack connection system for a simply supported bridge with a large gradient. Background technique [0002] In rack railway, the racks laid in the track mesh with the gears on the train to provide a large longitudinal force to the train, so as to obtain its strong gradient adaptability, and the maximum adaptable gradient can reach 480‰. At present, more than 100 rack railways have been built abroad, but almost none of them are built on simply supported bridges. With the continuous development of mountain tourist attractions in my country, the mountain cog railway is in urgent need of development. Due to the complex terrain of mountain scenic spots in my country, the construction of rack and rail lines is inevitable on bridges, and the longitudinal expansion and contraction of simply supported bridges is much larger than the required ra...
