Technical Field

The invention relates to the technical field of subways, also belongs to the technical field of electric control turning, and particularly relates to a subway electric control turning device.

Background

At present, in the electric energy applied to most metro vehicles, in the research of numerous transmission technologies, two main transmission modes of direct current transmission and alternating current transmission are selected according to different traction modes of the metro vehicles, and the electric energy enters an electric motor to finish vehicle traction through the motor. The direct current traction engine is complex in structure, direct current chopping needs to be completed through the semi-controlled thyristor, and therefore chopping voltage regulation and phase-controlled voltage regulation are combined. With the continuous development of the traction technology of the subway vehicles, the alternating current transmission of the asynchronous motor is applied to the traction technology, and meanwhile, with the advent of a voltage inverter for variable frequency and variable voltage, the alternating current transmission becomes the main traction technology, and in the 1990 s of European countries, the production of direct current transmission vehicles is stopped, and the vehicles quit the stage. As a current main metro vehicle traction technology, an alternating current transmission mode realizes control over a metro vehicle through a traction converter, and in order to realize traction conversion, a frequency converter needs to be used during metro vehicle design to make up for the problem of insufficient voltage level and the like. Such as germany and japan, three-level inverters of 1200V and 1700V have been used, respectively, and as technology advances, the inverters are added to a high-voltage module, so that output waveforms are better. Meanwhile, a speed sensor and a full electric brake are added in the alternating current transmission, so that the flexibility and reliability of electric traction are ensured.

However, because the metro of the inter-city rail transit is a device which is driven by a jack-weight machine to move and is connected and parallel by using the connecting columns made of stainless steel materials, when the metro needing to be maintained is required to turn or be corrected in a large radian in the metro tunnel, because the connecting part is in rigid pivot connection, in addition, a bending part with a corner of pi/2 is often formed when the general metro tunnel is led to a maintenance place, and stable turning cannot be achieved; the existing method is to manually disassemble the splicing rods for connection, temporarily support the splicing rods on the side wall of the subway tunnel by using pneumatic pistons, and then use a jack-weight machine to operate in combination with a manual lever.
