Description

Anti-deformation mute track

Technical field

The invention relates to the field of traffic planning, and in particular to an anti-deformation mute track.

Background technique

Vehicles such as trains, subways, and light rails need to be carried by orbits. Tracks play an indispensable role in modern life and are also a vital part of the traffic rules. The existing rails are formed by splicing a section of steel rails. Due to the need of thermal expansion and contraction, gaps need to be reserved between adjacent rails, whenever the locomotive passes the gap between adjacent rails, due to the wheels. In the shape of a circle, the arc surface of the wheel will fall into the gap, resulting in a rhythmic vibration that we usually hear. The locomotive noise is relatively large, the operation is not stable, the wheel wear rate is high, the service life is short, and the existing adjacent The sides of the two sections of steel rails are connected together through the connecting plates, and the positioning effect is poor. The ends of the adjacent two rails are easily deformed or even misplaced, which seriously affects the driving safety of the locomotive.

The fixing bolt passes through the outer mounting through hole chute and the inner mounting through hole chute, and the main insert block and the second middle supporting rail are connected by a fixing nut, and the upper running surface of the upper end of the main insert block and the first upper traveling rail respectively And the upper surface of the second upper traveling rail is parallel to each other.

The invention has the advantages that the above-mentioned anti-deformation mute track has novel structure, convenient installation and good use effect, and the gap required between the adjacent two sections of the rail is disposed inside one of the rails, and when the wheel passes the rail, the wheel can From the upper surface of the first traveling rail to the upper running surface of the upper end of the main insert, and then from the upper running surface of the upper end of the main insert to the upper surface of the second traveling rail, the circular surface of the wheel It does not need to get caught in the gap reserved between two adjacent rails, avoiding the vibration of the locomotive, reducing the noise of the locomotive, running more smoothly, the wheel wear rate is low, the service life is long, and the adjacent two sections pass the main rail. The insert block and the auxiliary insert block are inserted into the positioning connection, and the positioning effect is good, and the end portions of the adjacent two rails are prevented from being deformed and misaligned, thereby ensuring the driving safety of the locomotive.
