Device and method for increasing running speed of tramcar shallow groove turnout

Abstract

The invention discloses a device for increasing the running speed of a tramcar shallow groove turnout, which comprises a track bed, a steel plate and turnout steel rails, wherein the steel plate is laid and anchored on the track bed, the turnout steel rails are arranged on the two sides of the track bed, deep grooves with a certain thickness are sliced in the bottom of the steel plate according toan existing turnout rail type, the steel plate is clamped to the turnout steel rails through the deep grooves, and the deep grooves are used for limiting movement of the steel plate. The invention further discloses a method for increasing the running speed by using the device. When a tramcar wheel set quickly turns and passes through the curved track, the increased part of the turnout steel railplays a better role in protecting the wheel rim, and safe operation of the tramcar is guaranteed. According to the technical scheme, the construction period is short, the implementation is easy, and normal operation of an electric passenger train is not affected.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for tramway engineering, in particular to a device and method for increasing the running speed of a shallow groove switch of a tramway. Background technique [0002] The mixed right-of-way form is a specific road section where modern trams share the right-of-way with social vehicles. On a specific road section that adopts the mixed right-of-way form, a turnout can be arranged at the intersection of tram lines as a steering device for electric passenger cars. When two or more turnouts meet at one point, in order to avoid the impact of the harmful space of the frog throat on the tread of the wheel set, the turnout is usually designed as a shallow groove turnout, and the shallow groove turnout can be directly received by the wheel set flange. The impact of space. [0003] However, the design speed of shallow groove turnouts is often lower than that of ordinary turnouts, which affects the...

AI Technical Summary

Problems solved by technology

[0003] However, the design speed of shallow groove turnouts is often lower than that of ordinary turnouts, which affects the overall municipal traffic operation at the intersection. 10Km / h, the speed limit for downlink passing through the intersection is 5Km / h, the time to pass through the intersection is long, and the traffic pressure at this intersection is relatively high
