Description

  The present invention relates to a rail gripping braking device for a railway vehicle such as a train or a train traveling on a rail.

  Conventionally, there are two methods for braking the wheels of railway vehicles such as trains and trains. The first is a wheel braking method using a brake shoe, and the second is a disk braking method using a disk. In recent years, disc braking systems have become the mainstream in terms of quality, function, performance, and cost.

  However, no matter how good the disc brake is, if you drive on a curved road exceeding the allowable limit speed of railway vehicles such as trains and trains, the vehicle body However, the current situation is that it is inevitable that it will surface due to the law of inertia and derail and overturn.

  Therefore, in order not to cause the above-mentioned derailment / overturn accident, there is a demand for the early development of a braking device that can minimize the accident even if the vehicle travels at the wrong speed.

Then, the patent document of the railway vehicle braking device filed so far is introduced for reference. (See Patent Document 1.)
JP-A-6-247304

  The above-mentioned patent document is intended to stop a railway vehicle reliably in a short time by mounting it on a vehicle body and generating a strong braking force by directly adhering a brake shoe to a rail by a magnetic force. However, some concerns remain in terms of safety, reliability, and certainty.

  Therefore, in order to solve the above-mentioned problems, the present invention can surely adjust or stop the traveling speed of the vehicle (V) in an emergency or emergency, and can prevent derailment / overturn of the vehicle (V). Is to develop and provide a simple rail gripping braking device.

As a means for solving this problem, the braking device is positioned at the rail center portion of the rail vehicle at the center symmetrical position, and both the inner and outer side surfaces of the upper head of the rail are gripped by gripping members having a predetermined length. In an emergency or emergency, the traveling speed of the vehicle is adjusted to be reduced or stopped, and derailment / overturn of the railway vehicle is prevented.

  In addition, the braking device is provided with a combination of a plurality of inner cases that can be moved up and down by a predetermined dimension by means of moving means such as a guide case and a cylinder at the center of the rail at a symmetrical position in the center of the railway vehicle. The arm can be opened and closed at a predetermined angle by a moving means such as a cylinder, and arms with gripping members suitable for the outer shape of both the inner and outer sides of the upper part of the rail are provided on the left and right, respectively. And the arm with the gripping member closes instantaneously to grip the rail.

  As an effect of the present invention, the central part of the railway vehicle is located at the center of the rail at the left-right symmetrical position, and both the inner and outer side surfaces of the upper part of the rail are gripped by the gripping members having a predetermined length, in an emergency, emergency, etc. The speed of the vehicle is adjusted or stopped at a reduced speed, and the derailment / overturn of the railway vehicle is prevented, and the center of the rail is symmetrically positioned at the center of the rail with a guide case and a cylinder, etc. A plurality of inner cases that can be moved up and down are provided in combination, and the inner case can be opened and closed by a predetermined angle by a moving means such as a cylinder at a symmetrical position of the inner case, and the outer shape of both the inner and outer sides of the upper part of the rail Suitable arms with gripping members are provided on the left and right sides, the inner case extends in an emergency or emergency, and the arm with the gripping members closes instantaneously to grip the rails. In an emergency such as, reliably decelerate adjust or stop the running speed of the rail vehicle, and, like it is possible to allow prevent derailment, overturning of railway vehicles, in which exhibits the Naru extremely beneficial effect.

  As the best mode of this invention, the gripping member has a length corresponding to the minimum radius of curvature of the rail and both ends formed in an R shape, and has a cross-sectional shape with good contact efficiency that closely contacts both the inner and outer side surfaces of the upper head of the rail It is important to finish it.

  Therefore, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5. A braking device for a railway vehicle such as a train or a train traveling on a rail, the braking device being a railway vehicle (V). Gripping member (1) having a predetermined length (L) on the inner and outer side surfaces (LA1) (LA2) of the upper part of the rail (LA). From a rail gripping type braking device characterized in that the travel speed of the railway vehicle (V) is decelerated and adjusted or stopped in an emergency or emergency, and the vehicle (V) is prevented from derailing or overturning. Composed.

  The braking device can be moved up and down by a predetermined dimension (X) in the center of the rail (LA) at the center of the railroad car (V) by a guide case (2) and a moving means (CY1) such as a cylinder. A plurality of inner cases (3) are provided in combination, and the inner case (3) can be opened and closed by a predetermined angle (α) by a moving means (CY2) such as a cylinder at a symmetrical position of the inner case (3). ) Arms (4) with gripping members (1) adapted to the outer shape of both the inner and outer sides of the upper head are provided on the left and right sides, the inner case (3) is extended in an emergency or emergency, and the gripping members (1) It is comprised from the rail holding | grip type | mold brake device characterized by an attached arm (4) closing instantly and holding a rail (LA).

  Next, the outline of the structure of the present invention will be described. As shown in FIG. 6, the rail gripping braking device is installed at a position between a wheel (W) and a wheel (W) of a railway vehicle such as a train or a train. A reinforcing member (ST) is newly installed in the pedestal frame, and six sets of guide cases (2) and inner case (3) for gripping the left and right rails are combined with each other, and the inner case (3) 12 cylinders (CY2) with built-in compression coil springs (CY2) provided on the left and right ends of the inner case (3) are combined with 12 sets of arms (4) and gripping members (1) for gripping the rails. ) To support the arm (4). In addition, six cylinders (CY1) for vertically moving the entire inner case (3) are provided at the center portions of the guide case (2) and the inner case (3).

  Next, the operation procedure of the present invention will be described. First, during normal operation, the vehicle travels while adjusting the speed using a permanent disc brake (DB), but when an emergency stop is necessary, such as in an emergency or emergency. When the speed exceeds the allowable limit speed, the solenoid valve automatically opens, air is supplied to the rear chamber side of the cylinder (CY1), the cylinder (CY1) is extended, and the inner case (3) is held in place (the rail is gripped). Move to a possible position). Further, two compressed coil spring built-in cylinders (CY2) provided at the left and right ends of the inner case (3) are exhausted from the front chamber side, and the compression coil springs extend to attach the left and right gripping members (1).
