Laser measurement trolley system of rail train traveling space limit

Abstract

The invention relates to a laser measurement trolley system for a rail train traveling space limit, which comprises a trolley body, wherein a host computer is arranged on the trolley body and is installed on a host computer base, an inclined angle measuring device is arranged on the host computer base, walking wheels are arranged on the trolley body, a displacement sensor and a gear rotary speed sensor are connected with the trolley body and are arranged beside the walking wheels, and the displacement sensor and the gear rotary speed sensor are connected with the host computer. The laser measurement trolley system for the rail train traveling space limit has the advantages that the measuring accuracy is high, the repeatability is good, the labor intensity of a detecting operation is greatly reduced, the working efficiency is improved, a schematic diagram of states of a train operation can be simulated on site, and a rapid detection, an accurate maintenance and convenience in construction of a contact net and a track operation can be achieved. An access of a digital 3G (the third generation telecommunication) network can achieve a remote transmission, computer software with a browser / server (B / S) structure provides convenience in a data administration and a resource sharing, and an LINUX operating system provides convenience in the data administration and a user operation on site.

Description

technical field [0001] The invention relates to a device for detecting parameters between train running, railway track and catenary, in particular to a laser measuring trolley system for limiting the space of a railway train. Background technique [0002] With the development of my country's high-speed railways, the safe operation of trains, especially high-speed trains, has become an important part of national safety production, and the geometric parameters of the three contact surfaces during train operation are particularly important. The so-called three contact surfaces are: the contact surface between the left and right wheels of the train and the two tracks, the contact surface between the train pantograph and the catenary, the relationship between the three and the positional relationship between the three and the surrounding objects need to provide real-time high-precision Therefore, a professional measuring instrument that can provide accurate measurement, comprehen...
