Embodiment Construction

[0039] The following will combine Figure 1 to Figure 8 A detailed description of the subway double-track steel rail flaw detection vehicle provided by the present invention is an optional embodiment of the present invention. It can be considered that those skilled in the art can modify and polish it without changing the spirit and content of the present invention. .

[0040] Please refer to Figure 1 to Figure 8 , The present invention provides a subway double-track rail flaw detection vehicle, which includes a frame 1, a traveling subsystem 2, a flaw detection subsystem 3, a centering subsystem 4, and a control subsystem 5. The traveling subsystem 2, the flaw detection subsystem 3 , The centering subsystem 4 and the control subsystem 5 can be detachably installed on the frame 1; in a preferred embodiment of the present invention, the frame 1 can be formed by welding or plugging and connecting with round pipes. The various subsystems are connected to the basic frame 1 in a remov...

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 steel rail flaw detection system, in particular to a subway double-track steel rail flaw detection vehicle combined with ultrasonic scanning. Background technique [0002] When the train is accelerating and braking, and when passing through rail joints, bends and turnouts, it causes friction, squeezing, 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 travel. Compared with ordinary railways, subway trains are frequent and have a large passenger flow. As a measure to ensure the safety of line operation, rail flaw detection is one of the important tasks in daily maintenance, and the “skylight point” of subway operation is different from ordinary railways. It only needs to complete data in a limited and fixed time from midnight to early morning. For ten kilometers of rail damage detectio...
