Annular electric train capable of taking cars without stopping

An annular electric train capable of taking cars without stopping serves as a good idea for solving the problem of traffic congestion at present. How the cars get on and get off the train is the biggest question, and most facilities in the annular electric train are used for solving the problem. Description is as follows: a crane puts a base plate onto an accelerated transfer trolley, and the cars are driven on the base plate through a get-on ramp; the cars park in grooves of the base plate and stall; and a bent steel plate on the base plate clamps wheels of the cars. When needed train spaces on the train are about to arrive, the transfer trolley is started and accelerated, and the transfer trolley is relatively static when the speed of the transfer trolley is the same as that of the train spaces of the train. The base plate and the cars on the base plate are extruded on the train spaces of the train through a get-on inclined plate, and the base plate is fixed to the train spaces through magnetic force. The cars get on the train, and the transfer trolley returns to the original position. When the cars get off the train, guide wheels stretching out of the base plate are clamped into a getting-off inclined groove channel to continue to run on the train, and the base plate and the cars on the base plate are dragged out of the train; and after the cars pass through a get-off ramp, a speed reduction lane and a turning-around machine parkon a departure preparation lane. The bent steel plate, for clamping the wheels, on the base plate loosens. The cars get off. Taking of the cars on the train is completed. The base plate is lifted away by the crane to be stacked for preparation.
