Embodiment Construction

[0008] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0009] The present invention is mainly composed of a traveling platform 1 , a shaft encoder 2 , a support frame 3 , a measuring frame 4 , a laser 5 , a 3D camera 6 and a data processor 7 . Wherein, the traveling platform 1 is a rigid mobile platform based on railway tracks, and consists of a vehicle body 10 , wheels 11 , guiding wheels 12 and push rods 13 . Wheel 11, guide wheel 12 are installed in car body 10 both sides, and wheel 11 contacts with track upper surface, and guide wheel 12 conflicts with track side when car body 10 deflects, to guide car body 10. The traveling platform 1 adopts lighter material processing, promotes smooth walking, and is portable to install. It is recommended that traveling platform 1 draw a schematic diagram according to the number I added, so that the structure and function of the traveling platform can be ...

Abstract

The invention discloses a laser image method contact network measuring instrument. The laser image method contact network measuring instrument comprises an advancing platform, a shaft encoder, a supporting frame, a measuring frame, a laser, a 3D camera and a data processor. The laser and the 3D camera are fixed on the measuring frame; a fan-shaped laser surface emitted by the laser is upward and is symmetric to the advancing direction of the advancing platform; a lens of the 3D camera faces upwards and is biased towards the laser; the view field of the 3D camera is also symmetric to the advancing direction of the advancing platform; the shaft encoder measures the advancing distance, controls the laser to perform laser output and controls the data processor to collect and store the processed data. The 3D camera automatically identifies a laser spot, and a geometric parameter of the contact network is obtained by using the angle relationship between the pixel position of the camera imageand the polar coordinate of the camera body. The device is simple and convenient to operate, safe and reliable, and can accurately and continuously measure geometrical parameters of a plurality of railway contact networks.

Description

technical field [0001] The invention relates to the technical field of railway catenary parameter measurement, in particular to a measuring instrument for detecting and diagnosing geometric parameters such as catenary height and pull-out value. Background technique [0002] At present, the geometric parameters of the railway catenary are mainly measured statically, mainly including manual measurement of insulating rods and laser ranging methods. The measuring instruments using the above methods can only measure one position at a time. This measuring instrument takes a long time to measure and has low efficiency. Moreover, the geometric parameter information and the railway position need to be manually input, which is not conducive to data management. In view of the above technical defects, a laser image method catenary measuring instrument was developed, which can realize continuous measurement, high efficiency, automatic storage of measurement data and easy management.
