The invention provides a double-track profile measuring apparatus. The double-track profile measuring apparatus comprises two 2D laser sensors and two parallelly-arranged sensor support seats. The 2D laser sensors are arranged in sensor outer covers respectively. The sensor outer covers are arranged on two opposite sides of the sensor support seats respectively and are connected through a connection rod. One end of the connection rod is fixedly connected with one of the sensor support seats and the other end is connected with the other support seat through two pneumatic support rods. A linear bearing is arranged in the connection rod and is connected with the sensor support seats through connection flanges. Working edge depended wheels which are in frictional contact with a to-be-tested steel rail are respectively arranged on the two side faces. Encoders are arranged on the working edge depended wheels. Walking and supporting row wheels are arranged under the sensor support seats. Network ports are arranged in the 2D laser sensors. According to the invention, the walking and supporting row wheels are strictly corrected, so measurement accuracy and stability of the 2D laser sensor are greatly improved, and the double-track profile measuring apparatus is simple in structure and convenient to use.
Description
technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a dual-track profile measuring instrument. Background technique [0002] Whether the outline dimensions, straightness and twist of the rail meet the standards will affect the safety, stability and speed of the railway operation, so it is necessary to detect the outline dimension of the rail in time to ensure the normal operation of the train. In the prior art, most of the tools for measuring the profile of the double-rail head section of the rail first measure one side of the rail, and then measure the other side. This kind of measuring equipment is cumbersome to operate and has low detection efficiency. How to design a dual-track profile measuring instrument to realize dual-track simultaneous measurement to simplify the measurement operation and improve the measurement efficiency is a technical problem that needs to be solved urgently.
