Railway fastener system comprehensive performance detection device and detection method

Abstract

The invention discloses a railway fastener system comprehensive performance detection device and detection method. A sleeper is horizontally and transversely fixed on a cast iron platform, a steel rail is installed on a rail bearing surface of the sleeper, and a fastener system to be detected buckles the steel rail on the sleeper. A portal frame beam is installed on the cast iron platform throughportal frame supporting columns, a vertical loading base of a vertical loading actuator is installed on the lower surface of the portal frame beam, and a vertical loading end vertically extends downwards to the steel rail from the vertical loading base. The fixed end of a reaction frame is installed on the cast iron platform, a horizontal loading base of a horizontal loading actuator is installedat the supporting end of the reaction frame, and a horizontal loading end horizontally extends to the steel rail from the horizontal loading base. The detection device applies a vertical load and a horizontal load to the steel rail to be detected, the detection requirements of buckling pressure, static rigidity and longitudinal resistance of the steel rail are met at the same time, the load precision and the displacement precision of the vertical loading end and the horizontal loading end are high, and the detection precision and the detection efficiency are high.

Description

technical field [0001] The invention relates to the technical field of detection equipment. More specifically, it relates to a comprehensive performance detection device and detection method of a railway fastener system. Background technique [0002] The railway fastening system is divided into ordinary speed railway fastening system and high-speed railway fastening system. It is composed of elastic strips, rubber backing plates, spikes and other accessories. Different types of fastening systems include different types of accessories. [0003] The railway fastener system is an important part for fixing rails on sleepers or track slabs, and its product quality has a great influence on traffic safety. Rail longitudinal resistance, buckle pressure, and static stiffness are important testing items in the type testing of fastener systems. The existing detection equipment mainly has the following shortcomings: it cannot meet the detection requirements of rail longitudinal resist...

AI Technical Summary

Problems solved by technology

The existing detection equipment mainly has the following shortcomings: it cannot meet the detection requirements of rail longitudinal resistance, buckle pressure, and static stiffness at the same time; the rail slippage cannot be automatically identified during the detection process of rail longitudinal resistance, and manual judgment is required, which is likely to cause false detection; the detection results require manual inspection. Calculation; low detection efficiency and poor detection accuracy
