Description

  The present invention relates to a laser device for indicating a position in a rail longitudinal direction of track peripheral equipment, and a method of using the same.

  Railroad tracks are provided with rail and track peripheral equipment. The track peripheral equipment is, for example, a traffic light or an ATS (automatic train stop device) ground unit. Each track peripheral facility is installed at a predetermined position. The position of the track peripheral equipment is expressed in kilometers or the like based on the distance along the track from the starting point of the track. The distance along the track is measured along the rail.

  For example, as shown in FIG. 7, when installing the ground elements 6 a and 6 b of ATS-P (P-type automatic train stop device), the ground elements 6 a and 6 b are the predetermined distances Da and Db before the traffic light 7. It is installed at the point. The predetermined distances Da and Db are measured along the rail 4 with the position of the back plate of the traffic light 7 as a reference position. In order to indicate the reference position in the distance measurement, the position of the back plate of the traffic light 7 in the rail longitudinal direction X, that is, the back plate position is marked.

  The conventional marking of the back plate position will be described with reference to FIGS. As shown in FIG. 8, the worker W <b> 1 wears a safety belt and then goes up to the inspection table 71 of the traffic light 7 and lowers the swinging swing 101 from the back plate 72. The downward swing 101 is a weight suspended from the end of the thread. As shown in FIG. 9, the other two workers W2 and W3 stretch the string 102 from the downward swing 101 at a right angle to the rail 4 and mark the back plate position on the rail 4. In this way, at least three workers W1, W2, and W3 are required to mark the back plate position of the traffic light 7. Moreover, since one worker W1 goes up to the inspection table 71 of the traffic light 7 and a plurality of workers W1, W2, and W3 need to be coordinated, the work time takes 10 minutes or more. Furthermore, work on the inspection table 71 at a high place requires the use of a safety belt and is not easy.

  A track peripheral facility space information acquisition system that has a laser scanner mounted on a railroad vehicle and acquires three-dimensional position information of the track peripheral facility is known (see, for example, Patent Document 1). If the position information on the track peripheral equipment is acquired using this system, the distance along the rail between the track peripheral equipment can be calculated. Since this system uses a laser scanner, even if the equipment around the track is at a high place, work at a high place is not necessary for acquiring position information. However, since this system is configured on a railroad vehicle, it takes time to place and derail the railroad vehicle in use. For this reason, this system is suitable for the usage of acquiring the location information of many facilities around the track while traveling, but the usage of acquiring the location information of one or a few of the facilities around the track is efficient. Not suitable.

  A laser apparatus according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1 to FIG. 5, the laser device 1 indicates the position in the rail longitudinal direction X of the line peripheral equipment (not shown). Since the track peripheral equipment is located away from the rail 4, the position of the track peripheral equipment in the rail longitudinal direction X is the position in the rail longitudinal direction X of the leg of the perpendicular line that has dropped from the track peripheral equipment to the rail 4.

  The laser device 1 includes a base portion 2 and a light source portion 3. The base portion 2 is a portion that is placed on the rail 4 and engages with the rail head portion 41. The light source unit 3 is a part that is rotatably attached to the base unit 2 and emits laser light. As shown in FIG. 6, the optical axis L of the light source unit 3 is a plane P perpendicular to the rail longitudinal direction X when the light source unit 3 is rotated with the base 2 engaged with the rail head 41. The angle θ changes within. The angle θ of the optical axis L is an elevation angle when the horizontal is used as a reference for the angle.

  The base portion 2 has a groove portion 21 that engages with the rail head portion 41.

  The light source unit 3 is attached to the base 2 via a hinge 31. The axis 311 of the hinge 31 is perpendicular to the plane P including the optical axis L, and the axis 311 of the hinge 31 faces the rail longitudinal direction X when the base 2 is engaged with the rail head 41 (see FIG. 1). In FIG. 1, this plane P is represented by a straight line.

  The base 2 has an opening 22 that exposes a part of the rail head 41. The base 2 has a mark 23 on the periphery of the opening 22 indicating a position where the plane P including the optical axis L intersects the rail 4.

  A portion that comes into contact with the rail 4 when the base portion 2 is placed on the rail 4 is electrically insulated.

  Each configuration of the laser device 1 will be further described in detail. In the present embodiment, the base 2 has a rectangular top plate 24 in plan view and side plates 25 and 26 extending downward from the long sides of the rectangle (see FIG. 2). The top plate 24 and the side plates 25 and 26 constitute a groove portion 21 below the base portion 2. Since the width of the groove portion 21 is set to be slightly larger than the width of the rail head portion 41, the inner side of one side plate 25 is brought into close contact with one side surface of the rail head portion 41 when the base portion 2 is placed on the rail 4. When the base portion 2 is placed on the rail 4, the groove portion 21 engages with the rail head portion 41, and the orientation of the laser device 1 with respect to the rail 4 is determined. Specifically, the horizontal direction of the laser device 1 is determined so that the direction of the long side of the top plate 24 coincides with the rail longitudinal direction X.

  The opening 22 is formed near the center of the top plate 24. The mark 23 is attached to the periphery of the opening 22 on the top surface of the top plate 24. In the present embodiment, the mark 23 is a straight line having a width, and is formed as a groove on the top plate 24. Note that the mark 23 may be colored or the like. The mark 23 is not limited to a straight line, and may be a triangle or the like.

  The top plate 24 has a through hole 27 (see FIG. 1). The through hole 27 is for passing a metal fitting (carabiner) used when the laser device 1 is carried. The top plate 24 has a protrusion 28 (see FIG. 5). The protrusion 28 reduces the collision between the base 2 and the light source 3 when the light source 3 is folded.

  The base 2 is formed by molding a synthetic resin as described above. By selecting an appropriate synthetic resin as the material of the base 2, the base 2 is reduced in weight and electrically insulated while ensuring strength. By reducing the weight of the base 2, the laser device 1 can be easily carried and used. The portion that electrically insulates the base 2 is at least a portion that contacts the rail 4 when the base 2 is placed on the rail 4. In the present embodiment, the entire base portion 2 is formed of an insulating material, thereby further reliably preventing a short circuit such as an insulation joint of the rail 4. In addition, the material of the base 2 is not limited to a synthetic resin, and may be wood or a composite material.

  The light source unit 3 includes a housing 32, a laser light source 33, a battery 34, and a switch 35. The casing 32 is formed by molding synthetic resin or the like, is a bottomed lid having a waterproof function, and houses the laser light source 33, the battery 34, and the like. In the present embodiment, the laser light source 33 is a semiconductor laser and emits visible laser light. The casing 32 has a portion on the tip side through which the laser light emitted from the laser light source 33 is transmitted or passed. The battery 34 is a power source that supplies power to the laser light source 33. The switch 35 is used to turn on and off the electrical connection between the laser light source 33 and the battery 34, and is attached to the bottom of the housing 32 in the present embodiment. The lid 321 of the housing 32 is fixed by screws 36. The housing 32 has a handle 37 on the side surface. The handle 37 is a part that the user has when rotating the light source unit 3.

  When the laser equipment 1 configured as described above is used to irradiate the line peripheral equipment with laser light, the position in the rail longitudinal direction X of the optical axis L of the light source unit 3 is the irradiated part (laser light applied to the equipment around the line. Is the position in the rail longitudinal direction X. This position is indicated by a mark 23.

  The method of using the laser device 1 will be described by taking as an example the case where the track peripheral equipment to be used is a traffic light or the like. The method of using the laser device 1 is the same as that of the traffic signal even if the line peripheral equipment is other than the traffic signal.

  The worker carries the laser device 1 near the traffic light with the light source unit 3 folded on the base 2 (see FIG. 5). The worker places the base 2 of the laser device 1 on the rail 4 far from the traffic light. At this time, the side surface closer to the traffic light of the rail head 41 is brought into close contact with the inner surface of the groove portion 21 closer to the hinge 31. Thereby, the groove part 21 engages with the rail head part 41, and the direction with respect to the rail 4 of the base part 2 is decided.

  The worker holds the handle 37 of the light source unit 3 and rotates the light source unit 3 (see FIG. 6). When the light source unit 3 is rotated, the optical axis L rotates in a plane P perpendicular to the rail longitudinal direction X, and the angle θ changes. An operator turns on the switch 35 with the front end side (the side from which the laser beam is emitted) of the light source unit 3 is directed in the direction where the back plate of the traffic light is present, and emits the laser beam from the light source unit 3. Since the laser beam has excellent directivity, it travels straight in the direction of the optical axis L without spreading.

  The worker adjusts the angle θ of the optical axis L and the position of the base portion 2 in the rail longitudinal direction X so that the laser beam emitted from the light source unit 3 is irradiated on the back plate of the traffic light. Such adjustment is performed by rotating the light source unit 3 and moving the base unit 2 in the rail longitudinal direction X. It is visually confirmed that the back plate of the traffic light has been irradiated with the laser beam.

  When the back plate of the traffic light is irradiated with laser light, the position of the optical axis L in the rail longitudinal direction X is the position of the back plate of the traffic light in the rail longitudinal direction X, that is, the back plate position. The back position of the back plate is marked by the laser device 1. This back plate position is indicated by a mark 23. The worker confirms the position indicated by the mark 23.

  The worker marks the position indicated by the mark 23 on the rail head 41 exposed from the opening 22 with a chalk or the like. Using this mark as a reference position, the distance to other track peripheral equipment, for example, an ATS-P ground element is measured. The laser device 1 is moved to a position away from a reference position marked with a chalk or the like by a predetermined distance, and laser light is emitted from the light source unit 3 between the left and right rails, so that the position where the ground unit should be installed is directly Indicated. This is inking with laser light. In addition, when installing other track peripheral equipment according to the reference position, the movement of the laser device 1 after marking the reference position is omitted.

  By using the laser device 1 as described above, one worker can easily mark the back plate position of the traffic light in a short time. Further, since it is not necessary for the worker to go up to the inspection table of the traffic light at a high place, the work becomes easy. Furthermore, since the laser apparatus 1 does not use a railroad vehicle, it is not necessary to place or derail the railroad vehicle in use.

  As described above, according to the laser device 1 according to the present embodiment, the optical axis L of the light source unit 3 is rotated in the rail longitudinal direction X by the rotation of the light source unit 3 with the base 2 engaged with the rail head 41. Since the angle θ changes in the vertical plane P, it is possible to easily indicate the position of the line peripheral equipment in the longitudinal direction X of the rail by irradiating laser light from the light source unit 3 to the peripheral equipment of the arbitrary height. .

  Since the laser device 1 has the groove portion 21 that engages with the rail head portion 41 in the base portion 2, when the base portion 2 is placed on the rail 4, the orientation of the base portion 2 with respect to the rail 4 is determined.

  The axis 311 of the hinge 31 is perpendicular to the plane P including the optical axis L. When the base 2 is engaged with the rail head 41, the axis 311 of the hinge 31 to which the light source unit 3 is attached faces the rail longitudinal direction X. The angle θ of the optical axis L changes in the plane P perpendicular to the rail longitudinal direction X by the rotation of the light source unit 3.

  The base 2 is formed with an opening 22 that exposes a part of the rail head 41 and has a mark 23 on the periphery of the opening 22 that indicates a position where the plane P including the optical axis L intersects the rail 4. The position of the track peripheral equipment in the rail longitudinal direction X can be marked on the rail 4.

  Since the portion that comes into contact with the rail 4 when the base 2 is placed on the rail 4 is electrically insulated, even if there is an insulation joint of the rail 4 under the base 2, the insulation joint is not short-circuited.

  In addition, this invention is not restricted to the structure of said embodiment, A various deformation | transformation is possible in the range which does not change the summary of invention. For example, the track peripheral equipment to be used is not limited to a traffic light or a ground unit, but may be a sign or the like. Further, the light source unit 3 is not limited to one that emits visible laser light, and may emit infrared laser light. When the light source unit 3 emits infrared laser light, a user (worker) of the laser device 1 wears a device that visualizes infrared light so that the laser light applied to the track peripheral equipment can be visually recognized.
