Abstract
Description
BACKGROUND OF THE
In the related art, a switching device capable of detecting or switching on / off switching signals by the operation of a slider type movable terminal has been used. That is, as described in Application No. 10-2000-0053219, it is possible to detect a change in the state of a specific object by making it possible to detect or generate an on / off signal by reciprocating the movable terminal using the cam plate external operation knob .
That is, the conventional ON / OFF switching device can be used not only as an ON / OFF switching device, but also as an ON / OFF switching sensor capable of detecting a state change (movement) of a sensing object connected to an external knob of a cam plate The ON / OFF operation is switched according to the state in which the cam plate outer operation knob is rotated by 90 degrees.
However, according to the above-described conventional technique, since the ON / OFF signal is switched even if the cam plate outer operation knob is rotated at an angle of 90 degrees, there is a problem that the ON / OFF switching is not performed for the minute movement.
In addition, according to the conventional sensor device, the switching operation is performed only when an obstacle is sensed, and then the sensor is returned to its original position to be in a switch-off state. Therefore, have.
In addition, it is necessary to immediately detect an obstacle as well as an obstacle when a train is operated. In order to detect such a train derailment, a deviating sensing device must be additionally provided, thus increasing the cost and increasing the number of parts.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Those skilled in the art will readily appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims.

According to an aspect of the present invention, there is provided an obstacle and a deviation detecting apparatus comprising: an apparatus body having a space therein and installed in a train; A swivel shaft rotatably installed to protrude outward from the inside of the apparatus main body and having an outer end connected to a contact lever which is in contact with an obstacle and a derailment; A shaft support member installed inside the apparatus main body, for supporting the rotation shaft so as to prevent the rotation shaft from rotating; A position fixing unit installed on the apparatus main body and providing frictional force to restrain the rotation shaft from freely rotating; And a sensing unit for sensing whether the contact lever is rotating due to an obstacle or a derailment to detect an obstacle or a derailment by sensing a rotation state of the rotation shaft.
Here, the position fixing unit may include an interference ball installed in a receiving groove formed on an inner surface of the apparatus body and contacting the rotating shaft; And a spring elastically pressing the interference ball in a direction in which the interference ball closely contacts the rotation axis, wherein the interference ball and the spring are interposed between the shaft support member and the inner surface of the apparatus main body.
In addition, the rotation shaft may include a rotation engaging portion rotatably coupled to the apparatus main body, a lever engaging portion extending from the rotation engaging portion to the outside of the apparatus main body, A stopper groove to which the interference ball is inserted and coupled and an annular groove in which a support rib of the shaft support member is inserted and supported is formed on the outer periphery of the hub.
The apparatus main body further includes: a cylindrical portion; A first side wall coupled to one side of the cylindrical portion and connected to the rotation axis; And a second side wall coupled to the other side of the cylindrical portion to correspond to the first side wall, wherein a work hole is formed in the second side wall, and a cover member is detachably coupled to cover the work hole .
The position fixing unit may include an interference ball installed inside the apparatus body and contacting the rotation shaft; Wherein the interference ball and the spring are movably disposed between the shaft support member and the inner surface of the apparatus main body, and the hub of the rotation shaft has the interference It is preferable that a stopper groove which can be engaged with the ball is formed.
The sensing unit may include: a first wing member fixedly coupled to the rotation shaft and rotated together with the rotation shaft; A second wing member fixedly coupled to the rotation shaft and rotated together when the rotation shaft rotates; An obstacle detection sensor installed on the apparatus main body and sensing an obstacle when the first rotary wing is opposed to the first rotary wing; And a derailment detecting sensor installed on the apparatus main body and spaced apart from the obstacle detecting sensor to sense when the second wing member faces the obstacle detecting sensor.
Each of the first and second wing members is provided with a coupling hole for coupling to the rotary shaft by bolts. The coupling hole is formed as a long hole with a predetermined length in the circumferential direction, and the first and second wing members It is good to be able to adjust the installation angle.
According to the obstacle and derailment detecting apparatus of the present invention, it is possible to detect both obstacles and derailments when the train is operated, and it is possible to reduce the size and weight of the product by integrating the obstacle sensing structure and the derailment sensing structure.
In addition, since the obstacle and the derailed state can be continuously maintained, it is possible to continuously generate an obstacle and a deviation detection signal so that the train driver or the train monitoring device can recognize the obstacle and the derailment signal.
