Train rail bolt fastening mechanism

Abstract

The invention discloses a train rail bolt fastening mechanism. The train rail bolt fastening mechanism comprises a plurality of sleepers, grooves are formed in the tops of the two sides of the sleepers, rail stress plates are placed in the grooves of the sleepers, and steel rails are fixedly connected to the tops of the rail stress plates. According to the train rail bolt fastening mechanism, lockcatches are driven to move downwards through pull pieces, the lock catches of clamping stabilization blocks are sleeved on positioning pipes, and the through the rotation of an adjustment lever, theprinciple of thread propulsion is utilized, steel sliding push plates are driven to perform horizontal displacement, even if the lock catches on the two sides of the steel rails of the train rail boltfastening mechanism are pulled outwards to form a tightening state, the two sides of the steel rails are guaranteed to be more stable, the contact extrusion heights between steel rolling wheels and the steel sliding push plates are changed through the height displacement differences of inclined grooves in the bottoms of the steel sliding push plates, namely, adjustable extrusion abutting blocks are located in the grooves of positioning plates, so that the rail stress plates of the train rail bolt fastening mechanism have a space with partial displacement adjustment, and it is guaranteed thatthe steel rails are more accurately and stably fixed on the sleepers.

Description

technical field [0001] The invention relates to the technical field of train track bolt fastening, in particular to a train track bolt fastening mechanism. Background technique [0002] As an important part of the railway line, the track is an integral engineering structure. It consists of main components such as rails, sleepers, connecting parts, ballast beds, anti-climbing equipment and turnouts. The track is usually composed of two parallel rails, and the rails are fixed. Put it on the sleeper, under the sleeper is the ballast bed, and the connecting parts play a connecting role between the rail and the rail and between the rail and the sleeper. The main line tracks of my country's railways are divided into five types: extra heavy, heavy, sub-heavy, medium and light. One type, in which the sleeper is laid between the ballast bed and the rail to bear the force and vibration transmitted from the rail and to the ballast bed; at the same time, it is used to maintain the gauge a...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a train rail bolt fastening mechanism, which solves the problem that the U-shaped screw on the existing sleeper only squeezes and fixes the rail from top to bottom, and does not aim at The front and rear positioning constraints of the rails are completely restricted by the extrusion friction of the U-shaped screws. When a small-scale deviation occurs between the rails and the sleepers, the entire set of bolt fasteners needs to be completely removed. question
