Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric locomotives, in particular to a pantograph simulation test device. Background Art
[0002] The pantograph is an important component of electric railway vehicles such as electric locomotives and electric trains. Its main function is to obtain electrical energy from the contact network to drive the train. During the production and processing of the pantograph, in order to clearly understand the performance of the pantograph under different working conditions, such as the stability of the pantograph when running at high speed and its adaptability when passing through curves, it is often necessary to conduct simulation tests on the pantograph. Simulation tests can help optimize the design and working parameters of the pantograph to ensure its good performance and reliability in actual operation.
[0003] However, currently, when conducting simulation tests on pantographs, the pantographs are mostly installed on a special test bench for operation tests. Although this test method can meet most of the operation monitoring of the pantograph, in the actual use of the pantograph, it often encounters harsh weather environments, such as high temperature, rain or low temperature environments. The existing test equipment cannot meet the operation simulation tests of the pantograph in harsh weather environments, especially in cold and low temperature conditions. After the power grid and the pantograph surface are frozen, it will have a greater impact on the performance of the pantograph. Therefore, there is an urgent need for a pantograph simulation operation test device that can simulate harsh environments. Utility Model Content
[0004] In order to overcome the deficiencies in the background technology, the utility model discloses a pantograph simulation test device, which can not only perform simulated operation simulation test on the pantograph, but also perform simulation test in adverse weather environments, especially in freezing rainy weather, thereby providing strong support for comprehensive and efficient performance testing of the pantograph.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A pantograph simulation test device comprises a test room, wherein a circular track is laid in the test room, a mobile trolley capable of moving along the circular track is arranged on the circular track, a pantograph connected to a circuit of the mobile trolley is detachably mounted on the upper part of the mobile trolley, a circular power grid corresponding to the circular track and connected to an external power source is arranged on the upper part of the circular track, the pantograph is connected to the circular power grid and provides electric energy to drive the mobile trolley, a circular pipeline corresponding to an external water source and connected to the circular power grid is arranged on the upper part of the circular power grid, a plurality of nozzles for simulating rain spraying toward the circular power grid are arranged at orderly intervals on the lower surface of the circular pipeline, and a temperature control device for regulating the temperature in the test room is also arranged in the test room.
[0007] Furthermore, a number of support rods arranged around the circular track are evenly distributed on the outside of the circular track, and a power grid frame for erecting a circular power grid is provided on one side of the support rod body facing the circular track.
[0008] Furthermore, a connecting rod located on the upper part of the grid frame and used for fixing and installing the annular pipeline is provided on one side of the support rod body facing the annular track.
[0009] Furthermore, the temperature control equipment includes a high-power electric heater and a refrigeration and air-conditioning system.
[0010] Furthermore, the mobile vehicle includes a frame for installing a pantograph, and a traveling mechanism installed at the lower part of the frame and driven by a motor, and the pantograph is connected to a motor circuit in the traveling mechanism.
[0011] Furthermore, the circular track is a double-track circular track.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] By setting up the corresponding circular track and circular power grid, the railway track and power grid on which the train actually runs can be simulated, thus providing strong support for the subsequent pantograph simulation operation test;
[0014] By setting up a mobile car connected to the pantograph circuit, not only can the pantograph be driven to perform simulated driving tests, but the mobile car can also be powered by the connection between the pantograph and the ring grid, thereby further realizing the performance test of the pantograph;
[0015] By setting up annular pipelines and nozzles, water droplets can be sprayed on the annular grid and the pantograph that is in contact with and moves with the annular grid, thereby simulating the impact on the working performance of the pantograph in rainy weather, which provides great help for the pantograph test;
[0016] By setting up temperature control equipment, the temperature in the test room can be controlled. A high-power electric heater can be used to simulate a high-temperature environment in the test room. A refrigeration and air-conditioning system can also be used in conjunction with an annular pipeline spray to create a cold environment or a simulation of the grid pantograph being frozen, thereby achieving a simulation test of the pantograph in an extreme environment.
[0017] The utility model can not only carry out simulated operation test and inspection of the pantograph, but also can carry out simulated test and inspection in adverse weather environment, especially in freezing rainy weather, thereby providing strong support for comprehensive and efficient performance inspection of the pantograph.
