60kg/m steel rail No.9 turnout and transformation method thereof
The invention provides a 60kg/m steel rail No.9 turnout and a transformation method thereof. The transformation method comprises the following improvements that the pulling force and the insufficient displacement are reduced on the basis of an existing 60kg/m steel rail No.9 turnout. The 60kg/m steel rail No.9 elastic bendable switch rail single-point traction turnout for urban rail traffic is developed for solving the problems of an existing product, electric traction wrenching of the elastic bendable switch rail is achieved by optimizing the turnout part structure and adopting one switch machine, the electric equipment acquisition cost and the civil engineering cost are reduced, the service life of the switch rail is prolonged, and the production efficiency is improved. And the daily maintenance workload is reduced.
提供一种60kg/m钢轨9号道岔及其改造方法，包括如下改进:在现有60kg/m钢轨9号道岔基础上减小扳动力和减小不足位移。本发明针对现有产品存在的问题，开发一种城轨交通用60kg/m钢轨9号弹性可弯式尖轨单点牵引道岔，通过优化道岔零部件结构，采用一台转辙机实现弹性可弯式尖轨的电务牵引扳动，降低电务设备购置成本和土建成本，延长尖轨服役寿命，减少日常维护工作量。
