Embodiment Construction

[0023] The present invention firstly provides a special-shaped rail, which includes a rail head 11 , a rail waist 12 and a rail bottom 13 , and the rail also includes an arch 14 protruding from the surface of the rail. Preferably, the arch slope is located on the upper surface of the rail bottom.

[0024] In a specific implementation manner, the vertical cross-sectional shape of the arch slope in the length direction of the rail is trapezoidal. Preferably, the vertical cross-sectional shape of the arch slope in the rail length direction is isosceles trapezoidal, and the length of the upper bottom surface of the arch slope in the rail length direction is 20-70 mm, the height of the arch slope is 10-20 mm, and the arch slope The included angle between the slope and the bottom plane is 5-60°.

[0025] In a specific embodiment, the arch slope is arranged at a position between two adjacent bolt holes on the rail in the length direction of the rail. Preferably, the distance from t...

Abstract

The present invention firstly provides a special-shaped rail, which includes a rail head 11 , a rail waist 12 and a rail bottom 13 , and the rail also includes an arch 14 protruding from the surface of the rail. The present invention also correspondingly provides a rail glued insulated joint, the insulated joint comprising two series-connected special-shaped steel rails as described above. The glued insulated joint provided by the present invention can prevent large rail gaps from appearing at the junction of two steel rails in series, and can greatly reduce the possibility of failure of the glued insulated joint of the rails due to temperature stress and impact force of the train. Small. The glued insulated joint provided by the invention can fully resist the temperature stress change of the seamless line and the impact force generated during the operation of the train, and meets the development requirement of the cross-interval seamless line.

Description

technical field [0001] The invention belongs to the technical field of railway transportation, and in particular relates to a rail glued insulating joint and a special-shaped rail technology in railway construction. Background technique [0002] The application of track circuits is a technological breakthrough for trains to enter the electric age from the steam age, and the development of seamless lines is an important measure for the overall speed-up and structural modernization of railways. Rail insulating joints are one of the key structures that combine track circuits and seamless lines. The insulating joints of insulated track circuits and seamless turnouts of cross-section seamless lines must use glued insulating joints. Glued insulating joints are generally assembled and glued by standard rails, splints, insulating layers (including insulating slots, insulating sleeves and insulating end plates) and fasteners (including bolts, nuts and flat washers) according to certa...
