Abstract

A static parameter measurement device of a contact net comprises a rack, a control device and two measurement components. The two measurement components are symmetrically arranged and a central point of the rack is a symmetrical point of the two measurement components. Each measurement component comprises a rack, a steering engine, a rotary laser and an angular sensor. The rotary laser rotates around a rotary center. The rotary center and the central point of the rack are on the same horizontal level. In use, the rack is vertically arranged on a rail, a contact line to be tested is perpendicular to a plane where the rotary center and the central point of the rack are arranged, the steering engine drives the rotary laser to rotate around the rotary center until a light dot emitted by the rotary laser falls on the contact line to be tested, inner included angles alpha and beta between the rotary laser and the rack are recorded, and guide height and stagger value of the contact line to be tested are calculated according to alpha and beta. The static parameter measurement device of the contact net and a usage method thereof is not only high in measurement accuracy and good in stability, but also simple in structure and convenient to operate. Meanwhile, the static parameter measurement device of the contact net and the usage method thereof is capable of satisfying the demand for development of high-speed electrified railways.

Description

technical field [0001] The invention relates to a measuring device, in particular to a static parameter measuring device of a catenary and a method for using the same, and is particularly suitable for improving the accuracy and stability of the measurement. Background technique [0002] At present, there are mainly two methods of measuring the static parameters of the catenary: contact measurement method and non-contact measurement method. Among them, the contact measurement mainly uses the insulating rod method, which has large errors and potential safety hazards; the non-contact measurement mainly uses the principle of optical aiming and ranging, and the measuring instruments are optical measuring instruments and laser rangefinders. [0003] The non-contact measurement method is mainly based on the propagation speed of ultrasonic waves or light waves in the air, measuring the time difference between emission and reception, calculating the distance from the measuring point ...
