Technical Field

[0001] The utility model relates to the technical field of a high-speed railway pantograph electric-pneumatic training system, in particular to a high-speed railway pantograph electric-pneumatic training system. Background Art

[0002] With the continuous development of my country's transportation field, my country's influence on the international rail transit field is also growing, and its important position is increasingly reflected. In recent years, it has achieved brilliant achievements that have attracted worldwide attention. At the same time, the country's demand for talents in urban rail and high-speed rail transportation industries is also huge. More and more secondary and high-level vocational colleges and institutions of higher learning have begun to pay attention to the training of such special talents and set up relevant majors. Therefore, the need for teaching and training devices that can cooperate with relevant teaching content is becoming more and more urgent. For example, the teaching and training device for how to access the electric energy of high-speed standard EMUs is one of them. In the practical training of high-speed rail pantographs, mastering the structural characteristics, application inspection and management and maintenance of pantographs is a very important content in ensuring the safe operation of rail transit equipment.

[0003] After searching, the publication (announcement) number is: CN114627712A, which discloses a subway pantograph simulation training device, specifically related to the technical field of training devices, including a connecting shaft, the outer end of the connecting shaft is fixedly provided with a detection line and two first baffles, one end of the detection line is fixedly provided with an outer sleeve, the inner part of the outer sleeve is provided with a second fixed shaft, and the outer end of the second fixed shaft is provided with an inner sleeve. The present invention drives the detection line to move and contact the pantograph slide plate through a motor, and in this process, the friction between the detection line and the pantograph slide plate is monitored, and the contact pressure between the pantograph slide plate and the detection line is adjusted, so as to combine the friction force in the simulation process, and reasonably control the contact pressure between the pantograph slide plate and the detection line, so as to achieve the purpose of simulation training for subway operators, so as to maintain normal contact pressure while reducing the friction between the detection line as much as possible.

[0004] The technical solution in the application document still has shortcomings: the pantograph training device will generate electric current during simulation, and there are safety hazards in the training process due to the lack of protective structure. At the same time, the detection line moves in a straight line, and it is impossible to truly simulate the contact between the pantograph and the wires on the moving high-speed rail, which affects the actual effect of the training and makes the teaching effect not outstanding.
