Embodiment 1

[0020] like figure 1 As shown, in the present embodiment, a standard EMU electric coupler life test bench includes a coupler base 3 for installing a coupler test product 1, an electric coupler base 3 arranged on the coupler base 3 and connected to the coupler test product 1. Hook pushing table, power system 2 and control system 4 capable of driving the electric hook pushing table to reciprocate, the power system 2 includes a two-way cylinder 21 with two air inlets, a changeover cylinder 21 communicated with the two air inlets respectively Directional control valve 22 and gas source 26 communicated with reversing control valve 22, reversing control valve 22 adopts electromagnetic valve, described control system 4 includes program controller, described program controller and reversing control valve 22 electric connect.

[0021] Install the coupler test product 1 to be tested on the coupler base 3, connect the electric coupler push platform to the coupler test product 1, simulat...

Embodiment 2

[0027] like figure 2 As shown, on the basis of the above embodiments, in this embodiment, a pressure control valve 23 electrically connected to the program controller is communicated between the reversing control valve 22 and the air source 26 . The pressure control valve 23 can be used to change the gas pressure output from the pressure control valve 23, thereby simulating the pushing ability of the coupler test product 1 under different air pressures, so as to verify the assembly performance and low air pressure passing ability of the coupler test product 1. The pressure control valve 23 adopts a solenoid valve, so that it can be remotely controlled by a program controller, and it is convenient to adjust the air pressure in real time and quickly according to needs.

[0028] In this embodiment, a flow control valve 24 electrically connected to a program controller is communicated between the reversing control valve 22 and the air source 26 . The moving speed of the piston r...

Embodiment 3

[0033] On the basis of the above-mentioned embodiments, in this embodiment, the control system 4 further includes a pressure sensor and / or a flow sensor electrically connected to the program controller, and the pressure sensor and / or flow sensor are arranged at the commutation In the pipeline between the control valve 22 and the air source 26 .

[0034] It is easy to monitor the air pressure inside the gas circuit by using the pressure sensor, and it is easy to monitor the gas flow inside the gas circuit by using the flow sensor. According to the detected data, it is convenient to accurately control the air pressure or gas flow, improve the control accuracy, and enhance the experimental data. reliability.
