Abstract

To prevent derailment of a high-speed vehicle on a rail track with a curved railway wheel, and derailment caused by an earthquake.SOLUTION: A derailment prevention device body (8) is installed on right and left sides in a lower unit of a truck body (5) of a vehicle, and a derailment prevention thick plate (10) is stored to be capable of being slide vertically in a wide width groove (9) provided on it. Derailment is prevented such that: when the vehicle travels on a rail curved toward the right side, a left-side hook unit (7) rides up on a left-side rail (1) by centrifugal force, a left-side derailment prevention device body (8) moves obliquely upward toward a rail, and a front surface (11) of the derailment prevention thick plate (10) hits a side surface (3) of a rail head, then an L-shaped hook unit (13) hits a lower surface of an eave (4) of the rail head, furthermore a positioning pin (14) between the derailment prevention thick plates is cut off when the derailment prevention device body floats up, and then wheels (6) are returned to the rail by dropping after the derailment prevention device body is sprung up for more than 10 cm almost vertically by being guided by the derailment prevention thick plate.SELECTED DRAWING: Figure 3

Description

鉄道車両のカーブした線路上の高速時の脱線、及び地震による脱線を防止する技術分野 Technical field that prevents derailment of railway vehicles on curved tracks at high speeds and derailment due to earthquakes.

鉄道車両の脱線を防止する方法としては現在では脱線後、特設のガードレールによりレールより大きく外れることを防止しているが、車両自体の脱線防止の方法は開発されていないように思われる。 Currently, the method of preventing derailment of a railway vehicle is to use special guardrails to prevent it from going far beyond the rails after derailment, but it seems that no method has been developed to prevent the derailment of the vehicle itself.

車輛の構造に脱線を防止できる機構を加えてカーブした線路よりの脱線、及び地震による脱線を防止する。 To prevent derailment from curved tracks and derailment due to earthquakes by adding a derailment-preventing mechanism to the structure of the vehicle.

車輛の台車本体５の下部の左側と右側に脱出防止装置本体８を設置し、それに設けた広幅溝９に脱出防止用厚板１０が上下に滑動しうる様に収納されている。車輌が右側にカーブした線路を走るとき、遠心力により左側の車輪の鍔部７が左側のレール１の上にせり乗り左側の脱出防止装置本体８がレールに向かい斜上方に移動して脱出防止用厚板１０の前面１１がレール頭の側面３にぶつかり、そしてそのＬ字形鉤部１３がレール頭の庇４の下面にぶつかり、更に脱出防止装置本体が浮上することにより脱出防止用厚板との間の位置決め用ピン１４が切断される。そして脱出防止装置本体は脱出防止用厚板に導かれて、ほぼ垂直に１０ｃｍ以上もはね上げられた後落下し車輪６はレール上に戻り脱線は防止される。 Escape prevention device bodies 8 are installed on the left and right sides of the lower part of the bogie body 5 of the vehicle, and an escape prevention thick plate 10 is housed in a wide groove 9 provided therein so as to be able to slide up and down. When a vehicle runs on a track that curves to the right, the flange 7 of the left wheel rides on the left rail 1 due to centrifugal force, causing the left escape prevention device body 8 to move obliquely upward toward the rail to prevent escape. The front surface 11 of the plank 10 collides with the side surface 3 of the rail head, and its L-shaped hook portion 13 collides with the underside of the eave 4 of the rail head, and the main body of the escape prevention device floats up, causing it to become an escape prevention plank. The positioning pin 14 between is cut. Then, the main body of the escape prevention device is guided by the escape prevention thick plate and is thrown up almost vertically by more than 10 cm and then falls, and the wheels 6 return to the rails to prevent derailment.

又地震により台車本体５が飛び上るときは、左右の脱出防止用厚板のＬ字形駒部１３が左右のレール頭の庇４がぶつかり、左右の位置決め用ピン１４を切断し、更に左右の脱出防止装置本体８はその広幅溝９に篏合している脱出防止用厚板１０に導かれて、ほぼ垂直に１０ｃｍ以上も跳ね上がった後、元の位置に落下し、脱線は防止される。 In addition, when the main body 5 of the truck jumps due to an earthquake, the L-shaped pieces 13 of the left and right escape prevention thick plates collide with the eaves 4 of the left and right rail heads, cutting the left and right positioning pins 14, and further preventing the left and right escape. The prevention device main body 8 is guided by the escape prevention thick plate 10 that fits into the wide groove 9, and after jumping up almost vertically by more than 10 cm, it falls back to the original position, and derailment is prevented.

車両の脱線を防止できる機構を加えることにより、走行時の安全が保たれる。そして又、線路・改修による費用を軽減することができる。 By adding a mechanism that can prevent the vehicle from derailing, safety is maintained while driving. Moreover, the cost of track and repair can be reduced.
