Model for producing high-speed unballasted railway turnout tie and method for producing turnout tie

Abstract

The invention discloses a model for producing a high-speed unballasted railway turnout tie and method for producing the turnout tie; the high-speed unballasted railway turnout tie is prepared by putting a thread steel a, a prestressed wire and a steel bar truss in a model and filling concrete to the model after stretching the prestressed wire. The high-speed unballasted railway turnout ties with different lengths can be produced by using the same one model; the position of the steel bar truss cannot be deviated during the production process, the precision bias is reduced, thereby guaranteeing the precision of the high-speed unballasted railway turnout tie; the high-speed unballasted railway turnout tie produced by the method is high in both bearing capacity and the anti-fatigue ability; the service life is long.

Description

technical field [0001] The invention relates to the technical field of turnout sleeper production, in particular to a model for producing a high-speed ballastless railway turnout tie and a method for producing a turnout tie. Background technique [0002] The production technology of high-speed ballastless railway turnout sleepers is complex, with high standards and strict requirements. In order to reduce the impact force and friction force when the train is running, improve the stability of the train running, and meet the needs of the high-speed running of the train, it is necessary to ensure the accuracy of the high-speed ballastless railway turnout sleeper while improving the high-speed ballastless track sleeper. Bearing capacity and fatigue resistance of ballast railway turnout sleeper. [0003] The scope of application of different lengths of high-speed ballastless railway turnout sleepers is very different. At present, each model used to produce high-speed ballastless ...

AI Technical Summary

Problems solved by technology

[0003] The scope of application of different lengths of high-speed ballastless railway turnout sleepers is very different. At present, each model used to produce high-speed ballastless railway turnout sleepers can only produce high-speed ballastless railway turnout sleepers of the same length, resulting in low utilization of the model , multiple models need to be configured in the production process, and the input cost is relatively high

Moreover, the current model used to produce high-speed ballastless railway turnout sleepers cannot effectively guarantee the position of the steel truss in the high-speed ballastless railway turnout sleeper when producing high-speed ballastless railway turnout sleepers, and the position of the steel truss is prone to shift during vibration In the production process, the end of the high-speed ballastless railway switch sleeper will be deformed due to the poor sealing of the end forming orifice plate
