Detailed Description
The following explains an embodiment of the present invention with reference to the drawings.
As shown in fig. 1 and fig. 2, the double-deck corrugated bellows windshield for a railway vehicle according to the present embodiment includes a mounting frame 3, a docking frame 6, and a bellows assembly 1 fixed between the mounting frame 3 and the docking frame 6. The folding shed assembly 1 is a double-layer opposite wave folding shed. The folding shed assembly 1 comprises a cloth clamping section bar 7 and two layers of shed cloth 8, wherein the two layers of shed cloth 8 are arranged in a wave-pair mode and are clamped and fixed through the cloth clamping section bar 7. The double-layer folding shed structure is shown in figure 2, different shed cloth thicknesses can be adopted according to the requirement of sound insulation indexes, and sound insulation materials such as sound insulation pipes are added in the middle of the interlayer to ensure the sound insulation effect.
A cab apron pedal assembly 4 is arranged above an inner bottom of a folding shed assembly 1, adjacent butt-joint frames 6 are connected into a whole through a concealed padlock 2, a limiting rope 11 is arranged at the inner bottom of the folding shed assembly 1, and two ends of the limiting rope 11 are fixedly connected with the butt-joint frames 6 and a pedal mounting seat 10 fixed on a vehicle body respectively.
The limiting rope 11 needs to be selected according to an actual vehicle running line, the parameters needing to be determined are the length of the limiting rope and the elastic coefficient of the limiting rope, and the selection basis is vehicle curve-passing calculation, the lapping amount of a cab apron pedal and the centering force needed by a joint frame.
The double-layer opposite wave bellows windshield is also provided with an inclined pull rod 5, the lower part of the inclined pull rod 5 is connected with a pull rod seat on the butt-joint frame 6, and the upper part is connected with the vehicle body.
