Description

Switch

technical field

The invention relates to the field of railway switch structure design, in particular to a switch.

Background technique

Tramway turnouts are generally used to be buried in the road surface, and the top surface of the rail is flush with the road surface. The requirements for the stability, integrity, maintenance-free and long life of the turnout are relatively high. Common tram switch structures are: alloy steel integral type, welded assembly type. In addition, there are high manganese steel cast type and other types.

The traditional welded and assembled switch is mainly welded by a large backing plate, bottom plate, sliding bed platform and vertical wall. A deep gap will be formed between the sliding bed platform set at intervals, the vertical wall and the basic rail. Debris cleaning is more inconvenient.

For foreign welded and assembled point switches, such as BWG, the basic rail uses 75C1 grooved steel rail, and the point rail is processed by 80×80 square steel, which is designed to be elastic and bendable. Cover plates and end plates are provided on the top surface and both ends of the switch to protect the internal space of the switch frame. Due to the 75C1 British standard steel rail, domestic procurement is difficult; and this type of switch requires high welding technology and large deformation after welding.
