Train rail bolt fastening mechanism
Technical Field
The invention relates to the technical field of bolt fastening of train tracks, in particular to a bolt fastening mechanism of a train track.
Background
The track is an integral engineering structure, and is composed of main components of steel rails, sleeper, coupling parts, track bed, anti-climbing equipment, turnout and the like, wherein the track is usually composed of two parallel steel rails, the steel rails are fixedly arranged on the sleeper, the track bed is arranged below the sleeper, the coupling parts play a role in coupling between the steel rails and the sleeper, the main railway track in China is divided into five types of special heavy type, secondary heavy type, medium type and light type, and the sleeper is paved between the track bed and the steel rails and is used for bearing the force and vibration transmitted from the steel rails and transmitting the force and vibration to the track bed; the rail component is called sleeper, which can absorb partial vibration besides transmitting force vibration from rail to track bed, and the number of sleeper laid on railway line per kilometer is determined according to running speed and traffic volume of rolling stock. The number of the sleeper laid on the line with high running speed and large traffic volume of the rolling stock is large. The China railway lays about 1840 sleepers on the straight line every kilometer. At present, the connection between the sleeper and the steel rail in China is generally realized by mutually threaded connection of a U-shaped screw and a screw rod, and the steel rail is positioned and supported, but the screw rod is loosened due to long-term vibration of a train, so that the screw rod is knocked and detected for a long time by adopting a large number of workers, wherein small displacement deviation can occur between some rails and the sleeper due to the loosening of the screw rod, the screw rod is gradually increased, at the moment, the screw rod is manually reinforced by fastening equipment, the U-shaped screw on the conventional sleeper only extrudes and positions and fixes the steel rail from top to bottom, the front and back positioning constraint force is not needed for the steel rail, the constraint force is completely realized by virtue of the extrusion friction force of the U-shaped screw rod, and when small-range deviation occurs between the steel rail and the sleeper, the whole set of screw rod fastener is required to be completely dismantled, so that the operation is very troublesome, and certain trouble is brought to railway staff.
