Background
High-speed railways have become one of the most important transportation means in China. Has the advantages of high speed, short travel time, good safety, convenient and comfortable travel, low energy consumption, little environmental pollution and the like.
In high-speed railways, overhead contact systems are the main power supply equipment, through which electric locomotives obtain electric energy. The current required by strong power during electric traction must be received from the contact net through the pantograph at the top of the locomotive or motor car, and the current receiving mode is to adopt the current transmission of the pantograph of the motor train unit in sliding contact through the contact line of a pair of contact surfaces and the contact net. If the performance and the installation quality of the contact net are problematic, the contact surface of the contact line is slightly poor, and electric arcs and sparks can be generated; if the line is not smooth, the locomotive vibrates or shakes, and the stability of the pantograph is also affected, so that poor contact is caused. The contact failure between the pantograph and the contact net causes the separation of the pantograph and the contact net instantaneously, and the off-line state is a very dangerous running state. The electric arc and spark generated in the off-line process can directly burn or melt the surfaces of the contact line and the sliding plate of the pantograph, and can cause instant overvoltage to influence the driving safety. Therefore, to ensure good contact and reliable current taking of the pantograph and the contact line, ensure safe operation of a high-speed railway, a series of detection work is needed besides certain requirements on design, construction and operation of the contact line suspension so as to discover hidden danger in time, overcome some problems in contact of the pantograph and the net and ensure that the pantograph and the net are in a good working state.
The contact net detection principle is based on the triangulation principle, and measurement is achieved through four high-resolution line scanning cameras mounted on a base line. The whole set of detection system is called a contact net geometric detection beam, and is shown in fig. 1. The contact net geometric detection beam is required to be calibrated before being installed, the contact net geometric detection beam can be installed on the roof of a detection vehicle after calibration, and if faults occur in a laser generator, a linear array camera, a power line, a control line and a shell component (such as window glass) in a laser shooting assembly in the use process, the contact net geometric detection beam is required to be calibrated again after maintenance.
In the field calibration, the whole bow net detection calibration ruler needs to be taken to the upper part of the roof of the vehicle, the roof is 4 meters away from the ground, the weight of the whole calibration ruler is 28.7 kg, the calibration ruler needs to be taken to the roof of the vehicle and is very hard, the calibration ruler needs to be erected and fixed on the geometrical detection beam of the contact net after being taken to the roof, two persons are required to cooperate to be capable of being erected, the labor is wasted, and certain potential safety hazards exist.
