DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, an obstacle or a deviation detection apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 10, an obstacle or a deviation detection apparatus 100 according to an embodiment of the present invention includes an apparatus main body 110, a pivot shaft 120, a position fixing unit 130, A member 140 and a sensing unit 150.

The apparatus main body 110 has a cylindrical wall 111 and first and second side walls 112 and 113. The first and second side walls 112 and 113 are opposed to each other at both ends of the cylindrical wall 111 so that a space is formed between the first and second side walls 112 and 113. The apparatus main body 110 has a cylindrical shape, and the first side wall 112 is rotatably coupled to the pivot shaft 120.

A receiving groove 112a for receiving the position fixing part 130 is formed on the inner surface of the first side wall 112 by a predetermined length so as to extend toward the shaft hole h to which the rotating shaft 120 is coupled.

The second side wall 113 is formed with a work hole 113a and the cover member 114 is coupled to the outside of the second side wall 113 so as to cover the work hole 113a. The assembly position and attitude of the first and second wing members 155 and 156 of the sensing unit 150 to be described later can be adjusted through the operation hole 113a in a state where the cover member 114 is separated.

The rotary shaft 120 includes a rotary engaging portion 121 rotatably coupled to the first side wall 112 and a lever engaging portion 121 extending from the rotary engaging portion 121 to protrude outward from the apparatus main body 110. [ And a hub 123 extending from the rotary coupling part 121 to the interior of the apparatus main body 110 and having an outer diameter enlarged.

The lever engaging portion 122 is connected to a contact lever 10 which is in contact with an obstacle or in contact with a line when a derailment occurs. The contact lever 10 is formed so as to extend in a direction orthogonal to the rotation shaft 120 and is coupled to rotate integrally with the rotation shaft 120.

The hub 123 is located inside the apparatus main body 110 and is supported so as to be supported by the shaft support member 140 so as to be rotatable and is supported so as not to be separated from the rotation direction . To this end, an annular groove 123a to which the shaft supporting member 140 is coupled is formed on the outer periphery of the hub 123.

The hub 123 is formed with stepped mounting portions 123b and 123c so that the first and second wing members 155 and 156 can be mounted on the hub 123, respectively.

The position fixing unit 130 is for fixing the position of the pivot shaft 120 so as not to change its posture. The position fixing unit 130 includes an interference ball 131 and a spring 133. The interference ball 131 is received in the receiving groove 112a so as to contact the outer periphery of the hub 123 of the rotating shaft 120. [ The spring 133 is installed in the receiving groove 112a to elastically press the interference ball 131 toward the hub 123 side. A stopper groove 123d is formed in the outer periphery of the hub 123 to receive the interference ball 131 when the interference ball 131 is moved to a position facing the interference ball 131. 5, when the interference ball 131 is elastically pressed against the spring 133 and a part of the interference ball 131 is inserted into the stopper groove 123d as shown in FIG. 5 It is possible to prevent the rotation shaft 120 from rotating due to the weight of the interference lever 10 connected to the rotation shaft 120 and to maintain a stable posture. When the interference lever 10 collides with the obstacle or when the derailment comes into contact with the ground or the track when the train is running, the turning shaft 120 overcomes the frictional force by the interference ball 131 and rotates to detect obstacles and derailment .

The cover member 140 is fixed to the inside of the apparatus main body 110 and specifically fixed to the inside of the first side wall 112 so that the interference ball 131 and the spring 133 are inserted into the receiving groove Is disposed to cover the receiving groove 112a so as to prevent it from separating from the receiving groove 112a.

The cover member 140 also has an arc-shaped hub coupling rib 141 that is inserted into and supported by the annular groove 123a of the hub 123 so as to rotatably support the hub 123, 120 are prevented from moving in the axial direction or in other directions to maintain a stable posture.

The sensing unit 150 senses an obstacle or a derailment in accordance with the rotation direction of the rotary shaft 120. Specifically, the sensing unit 150 includes an obstacle sensing sensor 151, a derailment sensor 153, and first and second wing members (not shown) connected to the rotary shaft 120, 155, 156). The obstacle detecting sensor 151 and the derailment detecting sensor 153 are installed at positions spaced apart from the rotary shaft 120, and are installed at a predetermined distance from each other. 6, the obstacle detecting sensor 151 can detect the presence of an obstacle by detecting the obstacle in a non-contact manner when the first wing member 155 is rotated to a position facing each other as shown in FIG. 7, when the second wing member 156 is detached, the deviation detection sensor 153 detects the second wing member 156 in a non-contact manner when moving to the opposite position, do. Each of the obstacle detecting sensor 151 and the derailment detecting sensor 153 senses the first and second wing members 155 and 156 in a noncontact manner and includes a magnetic sensor using a magnet, Proximity sensors, and the like.

Each of the first and second wing members 155 and 156 is seated on the hub 123 of the pivot shaft 120 and coupled by a bolt and positioned to be symmetrical with respect to each other. Accordingly, the first and second wing members 155 and 156 can be moved by the angle that the first wing member 155 faces the obstacle detecting sensor 151, or the second wing member 155 can move along the rotation direction of the rotating shaft 120, (156) is moved by an angle facing the deviation detection sensor (153). Each of the first and second wing members 155 and 156 is coupled to the hub 121 of the rotary shaft 120 by means of bolts so that the obstacle detection or derailment detection function is normally performed according to the rotation angle of the rotary shaft 120 The installation position (angle) of the first and second wing members 155 and 156 can be adjusted. For this purpose, the bolt coupling holes 155a and 156a of the first and second wing members 155 and 156 are formed as slots having a predetermined length in the circumferential direction. Therefore, in the process of passing through the bolt coupling holes 155a and 156a using the plurality of bolts and coupling them to the mounting portions 123a and 123b of the hub 123, the posture of the first and second wing members 155 and 156 The rotation angle necessary for detecting the obstacle and detecting the deviation of the steering shaft can be adjusted to the best condition by finely rotating the steering shaft 120 with respect to the center of the coaxial shaft 120.

For example, when the obstacle contacts the lever 10, the pivot shaft 120 is rotated at least 27 degrees as shown in Fig. 6 so that the first wing member 155 is installed (The position facing the obstacle detection sensor). In the case of derailment, the rotation range of the rotary shaft 120 is relatively small. Therefore, as shown in FIG. 7, the second wing member 156 faces the derailment detection sensor 153 at an angle of about 9 degrees And can be adjusted to be installed at a position where it can be installed.

In addition, a wing-fixing cap 170 is further provided on the pivot shaft 120 so that the first and second wing members 155 and 156 can be stably engaged with the pivot shaft 120 and closely contacted thereto. The wing fixing cap 170 may have a bolt structure.

The operation and effect of the obstacle or deviation detecting apparatus 100 according to the embodiment of the present invention having the above-described configuration will be described as follows.

5, the first and second wing members 155 and 156 are connected to an obstacle detection sensor (not shown). The first and second wing members 155 and 156 are connected to an obstacle detection sensor 151 and the deviation detection sensor 153, respectively. At this time, the interference ball 131 of the position fixing unit 130 is held in a state of being engaged with the stopper groove 123d of the hub 123 so that when the train of the rotary shaft 120 is operated or stopped, The posture is maintained without being rotated by the load.

On the other hand, when there is an obstacle on the line during the train operation, the contact lever 10 is rotated in the direction of the arrow A by the obstacle 20 as shown in Fig. 6, the frictional force of the position fixing part 130 is overcome by the force generated when the contact part 120 contacts the obstacle 20, and the rotation shaft 120 rotates by a predetermined angle. When the rotary shaft 120 rotates, the first wing member 155 faces the obstacle detecting sensor 131, and the obstacle detecting sensor 131 detects that the obstacle is detected and generates an obstacle detecting signal .

Conversely, when the train derails, the contact lever 10 is brought into contact with the line or ground and is rotated in the direction opposite to the direction of the obstacle contact (direction B), as shown in Fig. In this case, as shown in FIG. 7, the second wing member 156 is moved to the position facing the deviation sensor 153, so that the deviation detection sensor 153 detects the second wing member 156 It is possible to detect whether or not there is a derailment.

As described above, when the obstacle is collided or derailed, the rotary shaft 120 is rotated by a predetermined angle to overcome the frictional force by the position fixing part 130. In the rotated state, The rotating shaft 120 can be maintained in a rotated state. Therefore, the obstacle detecting sensor 151 and the derailment detecting sensor 153 can be continuously moved to the opposite positions to continuously detect the first fixed wing member 155 or the second fixed wing member 156, Since the obstacle detection signal and the deviation detection signal do not occur as one-time but continuously, the driver or the monitor (monitoring apparatus) can accurately ascertain and recognize the obstacle and the derailment state so as to take subsequent actions.
