Abstract

The invention discloses a mobile steel rail flaw detection device. The mobile steel rail flaw detection device comprises a track; a chassis is arranged at the top of the track; adjustable brackets arefixedly connected to the two sides of the top of the chassis in the vertical direction; measuring equipment is fixedly connected to the front surface of the top of each adjustable bracket; each measuring equipment comprises laser profile measuring instruments, a controller and a display; the laser profile measuring instruments are embedded in the two sides of the bottom of each measuring equipment; the controller is fixedly connected to the center of the top of the chassis; a display is arranged on the back surface of the top of the chassis; and corresponding sides of the laser profile measuring instruments, the controller and the display are electrically connected through leads; the display is a notebook computer. According to the mobile steel rail flaw detection device, through coordination of the laser profile measuring instruments, the controller and the display, flaw positions of the surface of the track can be accurately controlled, the problem that an existing flaw detection device cannot accurately control the track surface flaw position is solved, and the mobile steel rail flaw detection device is worth of being popularized and used.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a mobile rail flaw detection device. Background technique [0002] Rail Transit: Urban rail transit is defined as a general term for fast and large-capacity public transportation that is usually powered by electric energy and adopts wheel-rail transportation. It generally includes subways and light rails, as well as modern trams. Urban rail transit refers to fixed lines. , laying fixed tracks, equipped with public transport facilities such as transport vehicles and service facilities. [0003] The rail vehicle is running on the track, and the rail transit personnel need to carry out flaw detection operations on the rail regularly, which requires the use of flaw detection devices. The existing flaw detection devices mainly use manual and ultrasonic pulse reflection methods for detection. , flaw detection hooks and other tools for flaw detection on the track, they can only de...
