DEVIATION PREVENTIVE AXLE RECEIVING BOX, RAIL GUARD AND AUXILIARY WHEEL TRAVEL DEVICE CAPABLE OF CONTINUING OPERATION OF LOW SPEED TRAVEL AFTER DERAILMENT, INSTALLED ON AXLE OF VEHICLE AND FIRMLY MADE WITH DEVIATION PREVENTIVE SAFETY WHEEL SO THAT DERAILED VEHICLE DOSE NOT TRAVEL BY LARGELY DEVIATING FROM RAIL OF ROADWAY IN TRAIN DERAILMENT, REPLACED WITH DERAILMENT PREVENTIVE SAFETY RAIL OF RAILROAD LINE

摘要

PROBLEM TO BE SOLVED: To prevent a vehicle from deviatively traveling by largely protruding from a roadway even in derailment by shaking of an earthquake.;SOLUTION: Safety wheels 1, 2, 31 and 32 are attached at intervals 5, 6, 11 and 12 of about 15 cm to the inside and the outside of main wheels 3 and 4 near both ends of an axle of the vehicle, and the intervals 5, 6, 11 and 12 of four places are left between the main wheels 3 and 4 and the safety wheels 1, 2, 31 and 32. When derailed to the left, a rail 13 is sandwiched by the interval 5, and a rail 14 is sandwiched by the interval 12. When derailed to the right, the rail 13 is sandwiched by the interval 11, and the rail 14 is sandwiched by the interval 6. Thus, the vehicle stops by running away by sandwiching the rails 13 and 14 by the four intervals 5, 6, 11 and 12. Derailing time rail reconnaissance iron wheels 19, 20, 21, 22 and 23, 24, 25, 26 installed in these respective intervals 5, 6, 11 and 12, are used in derailment.;COPYRIGHT: (C)2010,JPO&INPIT
