Abstract

The invention provides a steel rail cementing insulating joint. The steel rail cementing insulating joint comprises two steel rails connected in series, insulating end plates arranged at the joint of the two steel rails, insulating trough plates tightly attached to the two sides of the steel rails, clamping plates arranged on the outer sides of the insulating trough plates, and screw joint insulating assemblies used for fastening the clamping plates and the insulating trough plates to the steel rails. The screw joint insulating assemblies comprise bolts, nuts, gaskets and insulating casing pipes arranged on the outer circular faces of the bolts in a sleeving mode. The steel rails further comprise arch slopes protruding out of the surfaces of the steel rails, convex layers matched with the arch slopes are correspondingly arranged on the insulating trough plates, and concave openings matched with the arch slopes and convex layers are correspondingly formed in the clamping plates. The cementing insulating joint can sufficiently resist the temperature stress changes of seamless tracks and the impact force generated in the running process of trains, and the development demands of trans-regional seamless tracks are met.

Description

technical field [0001] The invention belongs to the technical field of railway transportation, in particular to the technology of glued insulating joints for rails 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 certain process requirements. ....
