Description

  The present invention relates to a switch adjuster and a branch structure.

  First, a general structure of a branching device structure for selecting a route of a railway vehicle will be described with reference to FIG. As a rolling device that plays a role of a branching device, for example, there is a rolling device described in Non-Patent Document 1 below (see FIG. 1). This turning device is composed of a converting device and a locking device, and is operated by an electric turning machine 101. Here, the conversion device makes the tongue rail 110 closely contact with or separate from the fixed basic rail 109, while the locking device keeps the close contact state of the tongue rail 110 and the basic rail 109. Is.

  The electric tipping machine 101 is installed on the sleeper 100 extending outside the gauge (outside the pair of basic rails 109). This electric switching machine 101 conducts a driving force from an AC motor 108, which is a driving source, in the order of a friction clutch, a reduction gear and a conversion gear with a conversion roller (each not shown), and operates by the conversion roller 102. To move.

  The moving rod 102 moves linearly in a direction orthogonal to the basic rail 109 when a cam (not shown) connected to the moving rod 102 is moved by a conversion roller. The electric tipping machine 101 is fixed to a switch adjuster 103 connected to the operating rod 102, an arm fitting 111 of the switch adjuster 103, a turning bar 104 connected to the arm fitting 111, and a tongue rail 110. The tongue rail 110 is converted by the connecting fitting 112 and whether or not the tip of the converted tongue rail 110 is in a normal position is checked by the front rod 105, the connecting bar 106 and the lock bar 107. If the tip of the tongue rail 110 is in a normal position, the operating bar 102 and the lock bar 107 are locked by a cam bar (lock piece) (not shown).

  Since the switch adjuster 103 is connected to the tongue rail 110 on the inside of the gauge (the inside of the pair of basic rails 109) from the outside of the gauge under the basic rail 109, the switch adjuster 103 is part of the rod portion 113 of the switch adjuster 103. Is inclined from the operating rod 102 toward the bottom of the basic rail 109. Further, in order to provide a so-called play between the stroke of the operating rod 102 and the stroke amount of the tongue rail 110 converted by the stroke, the rod portion 113 is configured to be slidable with respect to the arm fitting 111 of the switch adjuster 103. is there.

  Various inspections and measurements are performed in the branch structure as described above. For example, in the tongue rail conversion resistance measuring device described in Patent Document 1 below, an angle fitting is connected to a rod portion of a switch adjuster, and a load converter connected to the angle fitting is a rolling rod. Is located at the edge of. When the switch adjuster is moved by a manual handle attached to the electric turning machine, the load is transmitted through the angle fitting, and the load converter measures the conversion resistance of the tongue rail.

  However, as described above, with the Tonguerel conversion resistance measuring device, it is necessary to perform the work and test of connecting the angle mounting bracket to the rod part of the switch adjuster and the rolling rod at night when the railway vehicle does not run. . In addition, since the load is transmitted through the angle mounting bracket, accurate measurement cannot be performed as compared with the case of directly measuring from the front rod.

  The present invention has been proposed in view of the above circumstances. That is, an object of the present invention is to provide a switch adjuster and a branching device structure capable of accurately and easily measuring a load acting on a tongue rail.

  In order to achieve the above object, a switch adjuster according to the present invention is a switch adjuster for converting a tongue rail of a branching device that selects a route of a vehicle, and includes a rod portion extending from an outer side to an inner side of a basic rail. The first detection unit for detecting the load on the rod portion is attached to the boundary portion between the inclined portion formed in the middle of the rod portion and the straight portion connected to the lower side of the inclined portion. , Is characterized.

  The switch adjuster according to the present invention is characterized in that the connector portion of the first detection portion is arranged below the inclined portion.

  A switch adjuster according to the present invention includes an attachment portion attached to the inclined portion, a cover portion that covers the first detection portion, and a connector portion below the attachment portion to which an output cable of the first detection portion is connected. It has a detection part holder provided with.

  The switch adjuster according to the present invention detects the relative displacement between the arm fitting and the rod portion inside the arm fitting that is connected to the rolling rod attached to the tongue rail and through which the rod portion passes. The second detection unit is attached.

  In the switch adjuster according to the present invention, the second detection unit includes a detection unit and a detection unit, the detection unit is attached to the rod portion, and the detection unit is embedded in the arm fitting. It is characterized by

  In the switch adjuster according to the present invention, the second detection part is composed of a detection part and a detection part, and the detection part is provided in a tubular part which is passed through the rod part and the arm fitting. It is attached, and the detection unit is embedded in the arm fitting.

  In the switch adjuster according to the present invention, the tubular portion has a nut portion rotatable with respect to the tubular portion, and a tubular portion side rail portion that fits with the arm fitting, and the arm fitting is the It is characterized in that it has an arm fitting side rail part that fits with the cylinder side rail part.

  The branching device structure according to the present invention is characterized in that the switch adjuster described above is provided on the front side of the tongue rail and on the front side of the front side.

  The turnout structure according to the present invention is characterized in that a third detection unit is attached to an elbow fitting of a front rod attached to the tip of the tongue rail.

  The switch adjuster according to the present invention is a boundary between a slanted part formed in the middle of the rod part of the rod part extending from the outer side to the inner side of the basic rail and a straight part connected to the lower side of the slanted part. A first detection unit that detects the load on the rod is attached to the section. That is, the switch adjuster dives from the outside of the gauge under the basic rail and is connected to the tongue rail on the inside of the gauge, so that the rod portion tilts (or moves from the operating rail to the bottom of the basic rail). It has an inclined part that extends and inclines upward on the inside of the gauge) .The first detection part is arranged at the boundary part between this inclined part and the straight part connected to the lower side of the inclined part. ing. With this configuration, the first detection unit is arranged at a position distant from the rolling machine, and in the operation of the rolling machine, the first detection unit does not come into contact with the cover, ballast, sleepers, or the like of the moving rod. Therefore, the load acting on the tongue rail at the time of conversion can be accurately measured. In this way, since the first detection unit is arranged at a position where it does not interfere with the operation of the switch adjuster, it is possible to perform measurement even while the railway vehicle is running. In other words, it does not require frequent attachment and detachment. Further, in the switch adjuster according to the present invention, since the first detector is directly attached, the load acting on the tongue rail can be accurately measured.

  In the switch adjuster according to the present invention, the connector section of the first detection section is arranged below the inclined section. That is, the switch adjuster is provided with a connector section for outputting detection information from the first detection section. Therefore, the detection information by the first detection unit can be stored and managed in an external control device or the like, and the load acting at the time of conversion of the tongue rail can be analyzed. That is, at the time of installation work or maintenance work, a value can be confirmed on the spot by connecting a monitor tool for confirming the detection information by the first detection unit to the connector unit. Further, since the arrangement of the connector portion is below the inclined portion, the connector portion does not come into contact with the sleepers or the ballast. Therefore, the load acting on the tongue rail at the time of conversion can be accurately measured. In addition, it is easy to attach and detach the monitor tool via the connector portion.

  The switch adjuster according to the present invention includes a mounting portion that is mounted on the inclined portion, a cover portion that covers the first detection portion, and a connector portion that is connected to the output cable of the first detection portion below the mounting portion. It has a detector holder. With this configuration, the detection unit holder is attached to the inclined portion, so that the first detection unit is protected from the outside and the arrangement of the connector unit is fixed. That is, the arrangement of the connector portion is below the inclined portion, and the cable is connected below the rod portion. Therefore, the connector part does not come into contact with sleepers or ballasts, and it is possible to accurately measure the load that acts on the tongue rail at the time of conversion, and also by laying the cable along the lower side of the rod part. , The cable does not interfere with the operation during conversion.

  A switch adjuster according to the present invention is a switch adjuster which is connected to a rolling rod attached to a tongue rail and which detects a relative displacement between the arm fitting and the rod part inside an arm fitting through which a rod part passes. Two detectors are attached. With this configuration, the second detection unit detects the relative displacement amount between the rod portion and the arm fitting (hereinafter, the relative displacement amount between the rod portion and the arm fitting is referred to as “play amount”). The stroke amount of the tongue rail can be obtained from the difference between the stroke of the operating rod (rod portion) and the amount of play. Therefore, it is possible to observe the conversion of the tongue rails not only at night when the railroad vehicle does not run, but also at any time without installing the sensor directly on the basic rail.

  In the switch adjuster according to the present invention, the second detection unit includes the detection unit and the detection unit, the detection unit is attached to the rod portion, and the detection unit is embedded in the arm fitting. With this configuration, when the rod portion slides with respect to the arm fitting, the position of the detected portion with respect to the detection portion changes, and the amount of displacement thereof is detected. That is, this amount of displacement becomes the amount of play. Therefore, it is possible to observe the conversion of the tongue rail at any time without mounting the sensor directly on the basic rail.

  By the way, in the branch structure having a small amount of stroke of the tongue rail, since the amount of play is inevitably large, the tubular portion falls off the arm fitting due to the linear motion of the operating rod (rod portion). When the operating rod (rod portion) moves linearly in this state, the arm fitting and the rod portion rub against each other, and the thread groove of the rod portion is worn. To prevent this, if a long tube is used that does not fall off the arm fittings, the area where the rod and the inside of the arm fittings face each other is small. There is no.

  Therefore, in the switch adjuster according to the present invention, the second detection part is composed of the detection part and the detected part, and the detected part is attached to the tubular part which is passed through the rod part and the arm fitting. The detector is embedded in the arm fitting. With this configuration, even if there is a large amount of play, it is possible to observe the conversion of the tongue rails. Further, when the tube portion of the rod portion slides with respect to the arm fitting, the position of the detected portion with respect to the detection portion changes, and the amount of displacement thereof is detected. That is, this amount of displacement becomes the amount of play. Therefore, it is possible to observe the conversion of the tongue rail at any time without mounting the sensor directly on the basic rail.

  Generally, the nut portion of the tubular portion is welded, the tubular portion and the nut portion are integral members, and the nut portion does not rotate with respect to the tubular portion. However, in the case where the tubular portion has the detected portion, if the tubular portion integrated with the nut portion is screwed into the rod portion, the detected portion may not be properly arranged with respect to the detecting portion of the arm fitting.

  Therefore, in the switch adjuster according to the present invention, the tubular portion has a nut portion that is rotatable with respect to the tubular portion, and a tubular portion-side rail portion that fits with the arm fitting. It has an arm fitting side rail part that fits with the side rail part. With this configuration, only the nut portion rotates with respect to the rod portion, and the tubular portion does not rotate. Therefore, the detected portion of the tubular portion can be appropriately arranged with respect to the detection portion of the arm fitting. Further, a rail structure is realized by the cylinder side rail part of the cylinder part and the arm metal part side rail part of the arm metal fitting, and the respective rail parts are fitted and run, so that the cylinder part is straightened to the arm metal fitting. To slide. Therefore, the detected portion of the tubular portion can be appropriately arranged with respect to the detection portion of the arm fitting.

  When the tongue rail has a long branch structure, a plurality of switch adjusters are connected to the tongue rail and interlocked via a crank device. However, if the operation of any one of the operation rods (the rod portion) is delayed, the load may be unbalanced on one of the switch adjusters, resulting in a conversion failure. Therefore, in the branching device structure according to the present invention, the switch adjusters described above are provided on the front side of the tongue rail and on the front side of the front side. With this configuration, it is possible to detect whether the plurality of switch adjusters can work together at an appropriate timing. That is, the load applied to each switch adjuster, the operation shift of each switch adjuster, the strength with which the switch adjuster pushes the converted tongue rail can be measured by the first detection unit and the second detection unit. On the front side of the tongue rail, for example, insert a hydraulic cylinder from the tip side of the tongue rail, and apply an external force to force the tongue rail away from the basic rail with this hydraulic cylinder, so that the switch adjuster pushes the tongue rail. You can measure it. However, in the case of the switch adjuster on the front side of the front side, the hydraulic cylinder cannot be inserted in the same way as on the front side, and thus the strength with which the switch adjuster pushes the tongue rail cannot be measured.

  Due to aging of the rail, a slight gap may occur between the tongue rail and the basic rail near the tip of the tongue rail. In order to respond to this phenomenon, at work sites, by extending the front rod, the front rod is stretched between the tongue rails to open the tongue rails, and the tip of the tongue rails may be brought into close contact with the basic rail. is there. Since this means is not the original use of the front rod, an unexpected load is applied to the front rod.

  Further, according to the above means, since the tongue rail is brought into close contact with the basic rail by stretching the front rod, the force for pushing the converted tongue rail is also applied to the front rod. In detail, when the front rod is stretched between the tongue rails, the contact metal fitting of the rolling rod pushed and pulled by the switch adjuster and the connecting metal fitting fixed to the tongue rail will be slightly opened. . When the tongue rail is changed with this gap, the switch adjuster structurally can pull the tongue rail on the side away from the base rail, but cannot push the tongue rail on the side close to the base rail.

  Therefore, in the branch structure according to the present invention, the third detection unit is attached to the elbow fitting of the front rod attached to the tip of the tongue rail. Therefore, the load applied to the front rod can be measured by the third detection unit. Furthermore, in addition to the measurement result by the third detection unit, by carefully examining the measurement result by the first detection unit, which is the load applied to the tongue rail at the time of conversion, the state of the branch structure can be known.

  Hereinafter, a switch adjuster and a branching device structure according to an embodiment of the present invention will be described with reference to the drawings. FIG. 2 shows a branching device structure according to the first embodiment in which the switch adjuster 1 according to the first embodiment of the present invention is used, and FIG. 3 shows the switch adjuster 1. 5 and 6 show a switch adjuster 1a according to a modified example of the first embodiment of the present invention. In the following description, the tip side of the tongue rail 110 is the front side, the opposite side is the rear side, the inside of the gauge is the inside of the width of the basic rail 109, and the outside of the gauge is the outside, and the height of the basic rail 109 is the outside. The direction of depth is upward or downward.

  As shown in FIG. 2, the switch adjuster 1 is attached to the front side of the tongue rail 110 and is for switching the tongue rail 110. The switch adjuster 1 is connected to the operating rod 102 and extends from the outer side to the inner side of the basic rail 109, the arm fitting 22 attached to the tip end side of the rod portion 10, and the first arm attached to the rod portion 10. It has one detection part 26 and a detection part holder 29. The arm fitting 22 is connected to the rolling rod 104.

  As shown in FIG. 3, the rod portion 10 of the switch adjuster 1 is rod-shaped, and an inclined portion 11 formed in the middle of the rod portion 10 and a straight line that is closer to the tongue rail 110 than the inclined portion 11. And a part 12. The inclined portion 11 is inclined downward with respect to the axial direction when viewed from the electric rolling machine 101 side on the outside of the gauge. Due to the inclined portion 11, the rod portion 10 has a high side and a low side, and the straight portion 12 is connected to the low side. A bifurcated jaw portion 13 through which a jaw pin is inserted is formed on the rear end side of the rod portion 10 which is the higher side of the inclined portion 11 and which is connected to the operating rod 102. Further, a thread groove is formed on the lower end of the inclined portion 11 to which the rolling rod 104 is connected, and the locking nut 14, the tube nut 16, the arm fitting 22, and the nut 15 are directed toward the end. The lock nut 14 is screwed into the thread groove in this order. As the nut 15, two nuts having different sizes are coaxially connected.

  The tubular nut 16 has a configuration in which a nut portion 17 having a thread groove formed inside and a tubular tubular portion 18 having no thread groove inside are integrated. More specifically, the nut portion 17 and the tubular portion 18 are coaxially connected to each other. In the nut portion 17, two nuts having different sizes are coaxially connected.

  The arm fitting 22 has a structure in which a flat plate-shaped arm coupling portion 23 and a tubular arm tubular portion 24 having no internal thread groove are integrated. More specifically, the arm connecting portion 23 is connected to the outer peripheral surface of the arm tubular portion 24.

  The tubular portion 18 of the tubular nut 16 is inserted into the arm tubular portion 24 of the arm fitting 22. Since the distance between the nut portion 17 and the nut 15 is wider than the entire length of the arm cylinder portion 24, the arm fitting 22 slides between the nut portion 17 and the nut 15. That is, the relative displacement amount between the rod portion 10 and the arm fitting 22 due to the slide is the play amount X.

  Here, the relationship between the play amount X and the stroke amount of the tongue rail 110 will be described with reference to the drawings. FIG. 4 shows the operation of the switch adjuster 1 in the process of converting the tongue rail 110.

As shown in FIG. 4A, the nut 15 is brought close to the arm tubular portion 24 of the arm fitting 22, and the clearance amount X is provided between the nut portion 17 of the tubular nut 16 and the arm tubular portion 24. is open. In this state, when the operating rod 102 is actuated and the rod portion 10 is pushed in the direction of the arrow, the nut portion 17 is brought close to the arm tubular portion 24, as shown in FIG. A play amount X is opened between the nut 24 and the nut 15. That is, the rod portion 10 slides with respect to the arm fitting 22 by the amount of play X, but the arm fitting 22 does not move during that time. In this state, when the rod portion 10 is further pushed in the direction of the arrow, as shown in FIG. 4C, the nut portion 17 pushes the arm tubular portion 24, so that the arm fitting 22 is pushed. As a result, the rolling rod 104 is pushed and the tongue rail 110 is converted. That is, the stroke amount S ₂ of the tongue rail 110 corresponds to the difference between the stroke S ₁ of the operating rod 102 (rod portion 10) and the play amount X. The operation is the same as the above in the case of conversion to the opposite direction.

  As shown in FIG. 3, the first detection unit 26 detects a load acting on the rod unit 10, and is, for example, a strain sensor or the like. The first detection unit 26 is attached to a boundary portion between the inclined portion 11 and the linear portion 12 of the rod portion 10. The first detection unit 26 is connected to a connector unit 27 for outputting the detected information, and the connector unit 27 is arranged below the inclined portion 11 and on an almost extended line of the linear portion 12. In other words, the first detection unit 26 is, for example, a position where the first detection unit 26 does not come into contact with the cover of the operating rod 102, the sleeper 100, the ballast (not shown), the basic rail 109, the motor 108, and the like. The output cable 28 is attached at a position where it is easy to arrange it.

  The detection part holder 29 includes an attachment part 30 attached to the inclined part 11 of the rod part 10, a cover part 31 that covers the periphery of the inclined part 11 and the vicinity of the boundary part together with the first detection part 26, and a lower part of the attachment part 30. And a connector portion 27 to which the output cable 28 of the first detection portion 26 is connected. The output cable 28 has a cable plug 21, and the cable plug 21 is connected to the connector portion 27. The attachment part 30 has a structure such as a band or a clamp that is attached or detached, or is fixed by welding. The cover part 31 covers the periphery of the inclined part 11 and the vicinity of the boundary part and houses the first detection part 26 to protect the first detection part 26.

  As shown in FIG. 5 and FIG. 6, in the switch adjuster 1a according to the modified example of the first embodiment, the inclined portion 11a of the basic rail 109 is viewed from the electric rolling machine 101 side outside the gauge. It dives below and inside the gauge, it inclines upward with respect to the axial direction. In this case, of the rod portion 10a, the straight portion 12a on the lower side of the inclined portion 11a is connected to the operating rod 102. Therefore, a forked jaw portion 13 through which a jaw pin is passed is formed on the rear end side of the straight portion 12a, and a locking nut is provided on the higher side of the inclined portion 11a to which the rolling rod 104 is connected. 14, the cylindrical nut 16, the arm fitting 22, the nut 15, and the locking nut 14 are screwed in this order in the thread groove. Other configurations are the same as those of the switch adjuster 1 according to the first embodiment.

The second detection unit 32 is provided on the inner side in a state where the second detection unit 32 is passed. The second detection unit 32 is a unit that detects the amount of play X (in other words, a unit that detects the absolute position of the rod unit 10 with respect to the arm fitting 22), and is, for example, a magnetic sensor or an encoder. The second detection unit 32 includes a detection unit 33 and a detected unit 34. If the sensor is a magnetic sensor, the sensor is the detection unit 33 and the magnet is the detected unit 34.

  The detection part 33 is embedded in the arm cylinder part 24 of the arm fitting 22, and faces the rod part 10 inside the arm cylinder part 24. The detected portion 34 is attached to the outer peripheral surface of the rod portion 10. The detection part 33 and the detected part 34 are arranged to face each other.

The detected portion 34 is attached to the outer peripheral surface of the tubular portion 318. The detection part 33 and the detected part 34 are arranged to face each other.

  In the tubular nut 316, the tubular portion 318 and the nut portion 317 are separate members, and are rotatably connected to each other. More specifically, the tubular portion 318 has an annular flange 19 formed on the outer periphery of the end portion, and the flange portion 19 is fitted inside the nut portion 317, thereby connecting the tubular portion 318 and the nut portion 317. In the state, it is possible to rotate. The tubular portion 318 has a projecting portion 20 as a tubular portion side rail portion that projects outward from the outer surface. The length of the tubular portion 318 is longer than that of the tubular portion 18 of the switch adjuster 2 according to the second embodiment.

  The arm fitting 322 has a guide groove portion 25 as an arm fitting side rail portion in which the protruding portion 20 of the tubular portion 318 is arranged. The guide groove portion 25 is formed linearly in the longitudinal direction on the upper surface side of the inner peripheral surface of the arm cylinder portion 324. That is, the rod portion 10 and the arm fitting 322 relatively slide while the protruding portion 20 of the tubular portion 318 is fitted in the guide groove portion 25 of the arm fitting 322. In addition, the protrusion 20 may be linearly formed in the longitudinal direction on the upper surface side of the tubular portion 318.

Either is provided. The number of switch adjusters 1, 2, 3, 4 is arbitrary. That is, a plurality of switch adjusters 1, 2, 3, 4 may be provided on the front side of the tongue rail 110, and a plurality of switch adjusters 1, 2, 3, 4 may be provided on the front side.

  As described above, the branch structure according to the fifth embodiment is configured. Next, a branching device structure according to a sixth embodiment of the present invention will be described with reference to the drawings. FIG. 14 shows a branching device structure according to a sixth embodiment of the present invention, and FIG. 15 shows a front rod 35 used in the branching device structure. In the following description, a configuration different from that of the first embodiment will be described, and the description of the same configuration will be appropriately omitted.

  As shown in FIGS. 14 and 15, the front rod 35 is attached to the tip of the tongue rail 110. The front rod 35 includes a main body rod portion 36 arranged between the tongue rails 110, a bracket 37 attached to the main body rod portion 36, and an elbow fitting connected to both ends of the main body rod portion 36 via spherical bearings 38.

The switch adjusters 2, 3, and 4 according to the second embodiment, the third embodiment, or the fourth embodiment may be provided.

  As described above, the branch structure according to the sixth embodiment is configured. Next, effects of the switch adjusters 1, 2, 3, 4 and the branch structure according to each of the above-described embodiments will be described.

  As described above, in the switch adjuster 1 and the branching device structure according to the first embodiment, the first detection unit that detects the load acting on the rod portion 10 at the boundary portion between the inclined portion 11 and the straight portion 12 of the rod portion 10. 26 is attached (see FIG. 3). That is, the first detection unit 26 is attached to a position where it does not come into contact with the cover of the operating can 102, the ballast, the sleeper 100, the basic rail 109, the motor 108, or the like. With this configuration, the first detection unit 26 is arranged at a position distant from the electric tipping machine 101, and in the operation of the electric tipping machine 101, the first detection unit 26 causes the cover of the operating rod 102, the ballast, and the sleeper 100. Do not touch. Therefore, the load acting on the tongue rail 110 at the time of conversion can be accurately measured. In this way, the switch adjuster 1 can be measured even while the railway vehicle is running because the first detection unit 26 is arranged at a position where it does not interfere with the operation of the switch adjuster 1. In other words, it does not require frequent attachment and detachment. Further, since the switch adjuster 1 is directly attached with the first detection unit 26, the load acting on the tongue rail 110 can be accurately measured.

  The switch adjuster 1 according to the first embodiment and the first detection unit 26 of the branching device structure are connected to the connector unit 27 for outputting the detected information. Therefore, the detection information from the first detection unit 26 can be stored and managed in an external control device (not shown) or the like, and the load applied when the tongue rail 110 is converted can be analyzed. Further, the connector portion 27 is disposed below the inclined portion 11 and substantially on the extension line of the linear portion 12 (see FIG. 3). That is, the connector portion 27 is attached to a position where the output cable 28 of the first detection portion 26 can be easily arranged without coming into contact with the cover, the ballast, the sleeper 100, or the like of the operating rod 102. Therefore, the load acting on the tongue rail 110 at the time of conversion can be accurately measured.

  The switch adjuster 1 and the branching device structure according to the first embodiment include a detection unit holder 29 (see FIG. 3). The detector holder 29 includes an attachment portion 30 attached to the inclined portion 11 of the rod portion 10, a cover portion 31 that covers the periphery of the inclined portion 11 and the vicinity of the boundary together with the first detection portion 26, and a lower portion of the attachment portion 30. And a connector portion 27 to which the output cable 28 of the first detection portion 26 is connected. With this configuration, the first detection unit 26 is protected from the outside world, and the arrangement of the connector unit 27 is fixed. That is, the connector portion 27 is arranged below the inclined portion 11, and the output cable 28 is connected below the rod portion 10. Therefore, the connector portion 27 does not come into contact with the cover of the operating rod 102, the ballast, the sleeper 100, etc., and the load acting on the tongue rail 110 at the time of conversion can be accurately measured. By wiring along the lower side of the portion 10, the output cable 28 does not hinder the operation at the time of conversion.

The switch adjuster 2 and the arm fitting 22 of the branch structure according to the second embodiment are connected to the rolling rod 104 attached to the tongue rail 110, and the rod portion 10 passes through together with the tubular portion 18 of the tubular nut 16. In this state, the second detection unit 32 that detects the play amount X is provided inside (see FIG. 8). The detection part 33 of the second detection part 32 is embedded in the arm cylinder part 24 of the arm fitting 22, while the detected part 34 of the second detection part 32 is attached to the outer peripheral surface of the rod part 10, and the detection part 33 and the detected part 32 are arranged to face each other. With this configuration, when the rod portion 10 slides with respect to the arm fitting 22, the position of the detected portion 34 with respect to the detection portion 33 changes, its displacement amount is detected, and this displacement amount becomes the play amount X. That is, the second detection unit 32 detects the play amount X that is the relative displacement amount between the rod unit 10 and the arm fitting 22. The difference between the play amount X and the stroke S ₁ of the operating rod 102 (rod portion 10) is the stroke amount S ₂ of the tongue rail 110 (see FIG. 4). Therefore, it is possible to observe the conversion of the tongue rail 110 without attaching a sensor directly to the basic rail 109, not only at night when the railway vehicle does not run, but at any time zone.

  Furthermore, since the load applied to the tongue rail 110 at the time of conversion or the like can be known by scrutinizing the measurement result by the first detection unit 26, the position of the tongue rail 110 which is the measurement result by the second detection unit 32 and its position With the load, which is the measurement result of the first detection unit 32 at the position, for example, the position where the tongue rail 110 has stopped can be grasped at the time of a conversion failure.

In the switch adjuster 3 and the branch structure according to the third embodiment, the detection unit 33 is embedded in the arm tubular portion 324 of the arm fitting 322, while the detected portion 34 is the outer periphery of the tubular portion 318 of the tubular nut 316. It is attached to the surface, and the detection unit 33 and the detected unit 34 are arranged to face each other (see FIG. 9). Therefore, in the branch structure having a small stroke amount S ₂ of the tongue rail 110, even if the long tubular portion 318 is used because the play amount X is large, the detected portion 34 is attached to the tubular portion 318. As a result, the conversion of the tongue rail 110 can be observed.

  In the switch adjuster 3 and the tubular nut 316 of the branching structure according to the third embodiment, the tubular portion 318 and the nut portion 317 are separate members and are rotatably connected to each other. With this configuration, only the nut portion 317 rotates with respect to the rod portion 10, and the tubular portion 318 does not rotate. That is, even when the tubular portion 318 has the detected portion 34, when the tubular nut 316 is screwed into the rod portion 10, the detected portion 34 is arranged appropriately with respect to the detection portion 33 of the arm fitting 322. Only the nut portion 317 can be rotated while facing each other. Therefore, the detected portion 34 of the tubular portion 318 can be appropriately arranged with respect to the detection portion 33 of the arm fitting 322.

  In the switch adjuster 3 and the tubular nut 316 of the branch structure according to the third embodiment, the tubular portion 318 has the protruding portion 20 protruding outward from the outer surface. On the other hand, the arm fitting 322 is formed with a guide groove portion 25 in which the protruding portion 20 of the tubular portion 318 is arranged, and the guide groove portion 25 extends in the longitudinal direction on the upper surface side of the inner peripheral surface of the arm tubular portion 324. It is formed in a straight line (see FIG. 9). That is, the rod portion 10 and the arm fitting 322 relatively slide while the protruding portion 20 of the tubular portion 318 is fitted in the guide groove portion 25 of the arm fitting 322. With this configuration, a rail structure is realized by the protruding portion 20 of the tubular portion 318 and the guide groove portion 25 of the arm fitting 322, and the protruding portion 20 extends along the guide groove portion 25, so that the tubular portion 318 is positioned relative to the arm fitting 322. Slide straight. Therefore, the detected portion 34 of the tubular portion 318 can be appropriately arranged with respect to the detection portion 33 of the arm fitting 322.

  The switch adjuster 4 and the branching device structure according to the fourth embodiment include a plurality of detected parts 34 attached to the outer peripheral surface of the tubular portion 418, and a rotation stop member 445 that prevents the tubular nut 416 from rotating. There is. That is, the holding portion 450 of the rotation stopping member 445 is fitted to the upper side of the tubular nut 416 and the nut 15 at the tip end side of the rod portion 10, and the tubular nut 416 does not rotate. Therefore, one of the detected portions 34 of the tubular portion 418 can be arranged to face the detection portion 33 of the arm fitting 422 and be arranged appropriately.

  The diverter structure according to the fifth embodiment has the first detection unit 26 and / or the second detection unit 32 on the front side of the tongue rail 110 and on the front side of the front side, respectively. Any of the switch adjusters 1, 2, 3, 4 according to the fourth embodiment is provided (see FIG. 13). With this configuration, even if the switch adjusters 1, 2, 3, 4 are connected to the tongue rail 110 in a switch structure having a long tongue rail 110, each switch adjuster 1, 2, 3, 4 is connected. 4 can detect whether or not they can work together at an appropriate timing. That is, the load applied to each switch adjuster 1, 2, 3, 4 by the first detection unit 26 and the second detection unit 32, the operation shift of each switch adjuster 1, 2, 3, 4 and the tongs after conversion. The strength with which the switch adjusters 1, 2, 3, 4 push the rail 110 can be measured. Therefore, the play amount X of the switch adjusters 1, 2, 3, 4 and the like can be appropriately adjusted according to the measurement result.

  In the branching device structure according to the sixth embodiment, the third detecting unit 40 is attached to the elbow fitting 39 of the front rod 35 (see FIG. 15). With this configuration, the front rod 35 is used for the purpose different from the original use of the front rod 35 for the purpose of closing a slight gap between the basic rail 109 and the base rail 109 near the tip of the tongue rail 110 due to aging deterioration or the like. The load applied to the rod 35 can be measured by the third detection unit 40.

  In addition, the switch structure according to the sixth embodiment is any one of the switch adjusters 1, 2, 3, and 4 according to the fourth embodiment including the first detection unit 26 and / or the second detection unit 32. Is equipped. With this configuration, when the tongue rails 110 are switched while the front rods 35 are stretched between the tongue rails 110, the load applied to the front rod 35 and the load applied to the switch adjusters 1, 2, 3, 4 are measured. It is possible to know the state of the branching device structure by scrutinizing each measurement result.

  Here, the technical significance of the branching structure according to the sixth embodiment will be described with reference to the drawings, together with the use different from the original use of the front rod 35. FIG. 16 shows a state of connection between the switch adjuster 1 and the tongue rail 110 in the branching device structure according to the sixth embodiment.

As shown in FIG. 16, in the switch adjuster 1, the arm connecting portion 23 of the arm fitting 22 is attached to the rolling bar 104. The U-shaped pressing metal fitting 114 is welded to the upper surface of the rolling rod 104. While the connecting metal fitting 112 is sandwiched between the pressing metal fittings 114, the connecting metal fitting 112 is connected to the pressing metal fitting 114 with a bolt (see FIG. 16B. Illustration is omitted in FIG. 16A). ing. Here, the bolt hole of the connecting fitting 112 is formed to be slightly wider than the bolt hole of the pressing fitting 114 (and the outer diameter of the bolt) with a play Y. In such a structure, the front rod 35 is stretched between the tongue rails 110 for the purpose of closing a slight gap generated between the tongue rails 110 near the tip of the tongue rail 110 due to aging or the like. When the tip of 110 is made to be in close contact with the basic rail 109, the connecting metal fitting 112 and the pressing metal fitting 114 are separated by the amount of play Y, and a gap Z is created between the connecting metal fitting 112 and the pressing metal fitting 114. When the tongue rail 110 is changed with the gap Z, the switch adjuster 1 can pull the tongue rail 110 on the side away from the basic rail 109 (the right side tongue rail in FIG. 16), but the switch adjuster 1 is in close contact with the basic rail 109. The tongue rail 110 (the left tongue rail in FIG. 16) cannot be directly pressed. However, the rolling rod 104 also has a function of pulling the tongue rail 110 on the side away from the basic rail 109 (the right tongue rail in FIG. 16) with the force F ₂ , but the pair of left and right tongue rails 109 Since it is connected by the front rod 35, the tip of the tongue rail 110 (the left tongue rail on the left side in FIG. 14) that is in close contact with the basic rail 109 is attached to the basic rail 109 by the force F ₃ via the front rod 35. Pressed. That is, the force F ₁ that causes the switch adjuster 1 to bring the tongue rail 110 (the left tongue rail in FIG. 16) into close contact with the basic rail 109 is not transmitted due to the gap Z, while the tongue rail 110 (right side in FIG. 16). The force F _{2 for} separating the tongue rail of FIG. 16 from the base rail 109 is transmitted to the tongue rail 110 (the left tongue rail in FIG. 16) via the front rod 35, and the force F ₃ acts.

  Therefore, in the turnout structure according to the sixth embodiment, the load applied to the front rod 35 is measured by the third detection unit 40, and the load applied to the switch adjuster 1 is measured by the first detection unit 26. It is possible to know, as a state of the branching structure, whether or not a force of an appropriate magnitude can be applied to the rail in an appropriate state by closely examining. For example, when the measurement result by the third detection unit 40 is higher than a general value, it can be seen that the front rod 35 is used in a manner other than its original use. That is, since an excessive load is applied to the elbow fitting 39 of the front rod 35, if the elbow fitting 39 is broken, there is a possibility that the vicinity of the tip of the tongue rail 110 and the basic rail 109 will be greatly opened. Therefore, as shown in Table 1 below, if a comprehensive evaluation of the branching device structure can be made from the measurement result of the first detection unit 26 and the measurement result of the third detection unit 40, an external monitor tool, etc. Can be displayed on the screen, and the state of the branching device structure can be known by carefully examining each measurement result.

  For example, when the length of the front rod 35 is adjusted from an excessively long state to an appropriate state, the load acting on the switch adjuster 1 is reduced, and the tongue rail 110 cannot be pushed with an appropriate force. Therefore, it is necessary to readjust the switch adjuster 1. In this case, if the values of the first detection unit 26 and the third detection unit 40 can be confirmed at the same time, the work can be prevented from being redone and the work efficiency can be improved.

Depending on the adjustment of the length of the front rod 35, the state in which the tongue rail 110 is supported by the switch adjuster 1 changes while being dispersed into F ₁ and F ₃ . When the front rod 35 is too long, the force pushing the tongue rail 110 depends on F ₃ and the gap Z is opened. Therefore, if the front rod 35 to which excessive force is applied is broken or the like, not only is F ₃ not transmitted to the tongue rail 110, but the gap Z is originally open, so the tongue rail 110 is not opened. The supporting force may decrease significantly below the proper value even in F ₁ . Therefore, as shown in Table 1 above, it is significant to comprehensively evaluate the branching device structure from the measurement result of the first detection unit 26 and the measurement result of the third detection unit 40.

  As a reference example of the present invention, the front rod of the branching structure according to the sixth embodiment may be provided, and the switch adjuster may be provided with the first detection unit and / or the second detection unit at an arbitrary position. .

  Although the embodiment of the present invention has been described in detail above, the present invention is not limited to the above embodiment. The present invention can be modified in various ways without departing from the matters described in the claims.
