Abstract

The invention provides a double-rail flaw detecting car for subway steel rails. The double-rail flaw detecting car for the subway steel rails comprises a frame, a walking sub system, a flaw detecting sub system, a centring sub system and a control sub system, wherein the walking sub system, the flaw detecting sub system, the centring sub system and the control sub system are all detachably mounted on the frame; in response to the control of the control sub system, the walking sub system drives the frame and parts on the frame to walk along double rails of the subway; the flaw detecting sub system at least comprises flaw detecting wheels, which are positioned on the two sides of the steel rail during detection and used for ultrasonic detection; in response to the control of the control sub system, the centring sub system adjusts the positions and angles of the flaw detecting wheels; and the control sub system controls the walking sub system and the centring sub system in response to outside input or in an automatic way.

Description

technical field [0001] The invention relates to a rail flaw detection system, in particular to a subway double-track rail flaw detection vehicle combined with ultrasonic scanning. Background technique [0002] When the train accelerates and brakes and passes through rail joints, curves and switches, it causes friction, extrusion, bending and impact on the rail. Under these repeated actions, the rail is easily damaged. [0003] At present, the subway is becoming an increasingly important means of transportation for people to go out. Compared with ordinary railways, the subway trains are frequent and the passenger flow is large. As a measure to ensure the safety of line operation, rail flaw detection is one of the most important tasks in daily maintenance, and the "skylight point" of subway operation is different from ordinary railways. It only needs to be completed in a limited and fixed time. Ten kilometers of rail damage detection and other work, the disadvantages of low e...
