Description

  The present invention relates to a lock deviation detector and a lock deviation detection method used for a railway track switch, and more particularly, to a position of a notch provided in a lock cane connected to a tongrail and a lock. The present invention relates to a lock deviation detector and a lock deviation detection method for detecting deviation caused by the position of a piece.

  In FIG. 8, the structure of one Example of the branching device 50 of a railway track and the switch machine 30 is shown with a top view. FIG. 9 is a plan view of the vicinity of the locking cane 39 of the switch 30. Further, FIG. 10 shows a front view of FIG. 9 viewed from the X direction.

  As shown in FIG. 8, the switch 30 includes an operation can 36, a clutch 37, a drive motor 38, and a lock can 39. And the switch machine 30 is connected to the drive motor 38 via the magnet clutch 37 which is a power transmission means, and operates the operation lever 36. Hereinafter, the conversion function and the lock function of the turning machine 30 will be described.

(Conversion function)
The switch machine 30 includes a conversion mechanism for branching the track by closely contacting or separating the pair of tongrels 33a and 33b with respect to the basic rails 32a and 32b and switching the route of the train. That is, the turning machine 30 converts the rotary motion of the drive motor 38 into the linear motion of the operating can 36, and pushes and pulls the falling stick 35 connected to the Tongrel 33 at the tip of the operating can 36. Tong rails 33a and 33b are changed.

(Lock function)
Further, the switch 30 connects the lock cane 39 to the Tonglele 33 via the connecting rod 31 and moves the lock cane 39 in conjunction with the operation of the Tonglele 33. A lock function for maintaining the state of the rail 33 is provided. That is, as shown in FIG. 10, the turning machine 30 is locked and pulled out by inserting the lock piece 41 into the notches 42a and 42b provided in the lock canes 39a and 39b. It becomes possible to move. The lock can 39 is composed of a sub-lock 39b and a main lock 39a. The locking cane 39 is connected to the connecting member 34, and an adjusting screw and adjusting nut 45 for finely adjusting the position of the locking cane 39 are provided in the middle of the connecting member 34 (see FIG. 8). . An adjustment nut 45 is also provided on the side of the lock cane 39 (see FIG. 10). The lock deviation amount refers to the amount of movement of the lock cane 39 with respect to the center point of the lock piece 41 adjusted with an equal gap between the left and right sides of the lock piece 41.

  When the locking operation is performed at the final stage of the conversion operation, if the position of the locking cane 39 is largely shifted from the reference position, the lock piece 41 is notched 42a, 42b provided in the locking canes 39a, 39b. Can no longer be inserted. As the cause, for example, there are misalignment of the rails 32 and 33 and the turning machine 30 due to repeated train passage. In addition, foreign matter may be caught in the gaps between the Tongrels 33a and 33b and the basic rails 32a and 32b. In these cases, the tongrels 33a and 33b cannot be locked normally, which hinders safe driving of the vehicle.

  Therefore, at present, a maintenance worker on site regularly opens the inspection lid 43 provided on the falling machine 30 and looks into the inside of the falling machine 30. The balance of the left and right gaps of the lock piece 41 inserted into the notches 42a and 42b is checked to confirm that the lock piece 41 is positioned at the center of the notch 42. And when the shift | offset | difference has arisen, the position of the locking rods 39a and 39b was adjusted with the adjustment nut 45 of the connection member 34, and the adjustment nut 45 of the locking rod 39.

  In addition, depending on the branching device 50, there is a unique “癖” in an appropriate positional relationship between the turning machine 30 lock piece 41 and the notches 42a and 42b, and the lock piece 41 is removed from the center position of the notches 42a and 42b. There is a case where so-called “one-sided adjustment” is performed in which adjustment is performed by shifting.

  Conventionally, a lock error detector that detects a shift between the lock piece 41 and the notches 42a and 42b has been used. This lock error detector detects whether or not the deviation between the lock piece 41 and the notches 42a and 42b exceeds a threshold value using an optical sensor composed of a light emitting element and a light receiving element.

  Patent Document 1 discloses a lock error detector obtained by improving the lock error detector using the optical sensor. That is, there is disclosed a turning machine provided with a lock error detector that easily confirms whether the position of the lock rod is appropriate without imposing the skill of the operator. Here, the turning machine is integrated with the locking mechanism connected to the Tongrel, the lock piece provided so as to be able to enter and leave the notch provided there, and the turning machine case. A pair of fixed slit members provided integrally and a moving slit member provided integrally with the locking cane. A fixed slit is formed in each of the fixed slit members. The moving slit member is formed with a plurality of moving slits, and the range of formation is an overlapping range that overlaps with the fixed slit when the lock is in the reference position, and a left portion that extends to the left of the fixed slit. It describes that it has a range and a right range that extends to the right of the fixed slit.

  In addition, Patent Document 2 discloses a tipping machine using a sensor terminal that enables a display corresponding to a narrow range closer to 0 point while maintaining the conventional step display function of the amount of lock deviation. A lock deviation detector is disclosed. In this case, the lock deviation amount detector of the switch machine is provided with an indicator that displays the detected lock deviation amount in a plurality of ranges (B, CR, CL, etc.), and is the most It describes that it has a display mode switching means for switching a range close to zero of the shift amount to a relatively wide range B and a relatively narrow range A.

Japanese Patent No. 5006760 JP 2010-215044 A

  In a conventional lock error detector, whether the tipping machine is normal or abnormal is displayed on, for example, a pilot lamp in a monitoring room or the like, and it is determined that the amount of shift of the lock canister is greater than a specified value. The alarm was raised only when For this reason, it is difficult to determine whether or not the amount of shift of the lock must be adjusted during maintenance work on site, and maintenance workers must perform adjustment work while looking into the lock piece in the back of the machine. I had to. This maintenance work is not only poor in workability, but also has a problem that the consistency of the quality of the maintenance work cannot be secured because it is based on the experience and intuition of maintenance workers.

  In addition, the conventional lock error detector shown in the cited document 1 has improved the problems of the conventional lock error detector. For example, the lock piece is notched according to the “癖” of the branching device. Not only is workability worse when performing so-called `` offset adjustment '' such as making adjustments that are offset from the center, but it is also based on the experience and intuition of maintenance workers that the quality of maintenance work cannot be ensured was there.

  Further, the lock shift amount detector of the switch using the sensor terminal shown in the cited document 2 is displayed by the LED meter as described in the cited document 2, so that the shift amount can be grasped intuitively. In addition, there is a problem that fine fine adjustment cannot be performed because the state display is gradual.

  The purpose of this application is to solve such problems, improve the workability of the shift adjustment of the lock in the maintenance work on site, and ensure the consistency of the quality of the maintenance work and the lock deviation detection. Is to provide a method.

  In order to achieve the above object, a lock deviation detector according to the present invention provides a shift deviation between a position of a notch provided in a lock cane connected to a Tongrel and a position of a lock piece. Display the amount of deviation between the detector, the position of the notch, and the position of the lock piece as a numerical value, or indicate the deviation. And a display unit for displaying. Hereinafter, “numeric display” and “continuous display”, which are features of the display method of the lock deviation detector of the present invention, will be described. Further, “ratio display” and “voltage display”, which are the characteristics of the display unit of the lock deviation detector of the present invention, will be described.

(Numeric display)
With the above configuration, the amount of shift of the lock cane is measured numerically in the maintenance work of the switch, and thereby the deviation caused by the position of the notch provided on the lock cane and the position of the lock piece. Transitions are properly detected. Further, the shift of the lock cane measured by the detection unit is displayed as a numerical value by the display unit, or the shift is displayed. In the past, maintenance work that was performed while looking into the lock piece in a deep place inside the machine would check the display on the switch machine where the deviation was displayed numerically. Can be achieved. Thus, for example, when adjusting the shift amount of the lock canister, or when performing so-called “offset adjustment” in which the lock piece is shifted from the center of the notch in accordance with the “癖” of the branching device. By displaying numerical values, etc., their workability is greatly improved. In addition, since the maintenance work conventionally performed by the maintenance worker based on experience and intuition is performed based on the deviation displayed numerically, the consistency of the quality of the maintenance work can be ensured.

(Continuous display)
Further, in the maintenance work of the turning machine, the shift of the lock cane is continuously measured by the detection unit, and the shift caused by the position of the notch provided in the lock cane and the position of the lock piece. Can always be detected. Further, the shift of the lock cane measured by the detection unit is continuously displayed on the display unit. Conventionally, the maintenance work that the maintenance worker has performed while looking into the lock piece in the back of the machine, confirms the display unit that continuously displays the deviation provided on the site. Achieved. As a result, for example, when performing so-called “offset adjustment” in which the lock piece is adjusted by shifting from the center of the notch according to the “癖” of the branching device, the workability is greatly improved. In addition to the improvement, it is possible to adjust the offset based on the numerical values displayed continuously, not the experience and intuition of the maintenance worker, thereby ensuring the consistency of the quality of the maintenance work.

  Further, the lock deviation detector detects the ratio of the gap amount on both sides generated by the notch and the lock piece by calculating from the deviation amount of the lock cane with respect to the lock deviation detector, and the display unit Preferably displays the gap amount or ratio numerically. Thus, by displaying the shift of the lock cane in the ratio of left and right, particularly inexperienced maintenance workers can easily determine the degree of shift intuitively.

  In addition, the lock deviation detector includes a measuring unit that measures the position of the moving measuring piece provided on the locking cane by a voltage generated in the linear sensor, and the detecting unit locks the voltage from the voltage value measured by the measuring unit. It is preferable to calculate the amount of deviation of the can and display it on the display unit. As described above, the shift amount can be detected continuously and numerically by using the linear sensor. In addition, numerical displays that are easy to understand for on-site maintenance workers are continuously displayed, which not only greatly improves workability, but also ensures consistency in the quality of maintenance work.

(Voltage display)
The lock shift detector includes a measuring unit that measures the position of the moving measuring piece provided on the lock cannula using a voltage generated in the linear sensor, and the detecting unit shifts the voltage value measured by the measuring unit. The amount is preferably displayed as it is on the display unit. As described above, the shift amount can be detected continuously and numerically by using the linear sensor. Further, by displaying the voltage value generated from the linear sensor as it is, the adjustment / maintenance worker can determine the degree of deviation based on the voltage value with which he / she is used.

  The lock deviation detector includes a threshold value input unit that sets a threshold value related to a numerical value, a storage unit that stores the input threshold value, and a threshold value determination unit that determines whether the numerical value exceeds the threshold value. It is preferable that the input unit includes a threshold value input unit that can set an arbitrary threshold value at the site. This allows the threshold input unit to set the threshold of the switchboard in the field taking into account the “癖” of the switch, and adjust the threshold according to the weather conditions of each season, etc. The effectiveness of determination by the determination unit can be increased.

  In the lock deviation detector, it is preferable that the threshold value input unit is a threshold value indicating that the numerical value is at least an abnormal level, and a numerical value lower than the threshold value and the numerical value should be alerted. As a result, it is possible to raise a caution alarm at the site before detecting an abnormality, improve the workability of the shifting adjustment of the lock cane in the site maintenance work, and improve the quality of the maintenance work.

  In addition, the lock deviation detector transmits a signal that can determine which threshold is used for each of the cases where the threshold determination unit exceeds a plurality of thresholds set by the threshold input unit, and the display unit When a signal is received, it is preferable to issue an alarm that can determine which threshold is used. This makes it possible to properly determine the deviation caused by the notch and the lock piece provided in the lock cane, improving the workability of the lock cane shift adjustment in maintenance work on site, It is possible to ensure consistency in the quality of maintenance work.

  In addition, the lock deviation detector has a threshold value stored in the storage unit and a measured deviation amount. The lock deviation detector has a display unit and is a detachable switch monitor or a portable terminal. It is preferable to provide an output unit for outputting to the machine monitor. As a result, the field maintenance staff can perform maintenance work while referring to the threshold value record and deviation amount record entered for each switch, and the characteristics and habits of the branching device Can be easily grasped.

  In addition, the lock deviation detector is a switch monitor with the output unit attached with at least information displayed on the display unit, a switch monitor with the output unit removed, or a switch as a portable terminal. It is preferable to have a transmission terminal means for transmitting to a single machine monitor. As described above, the information output from the lock deviation detector is displayed on the switch monitor in the attached state or on the switch monitor in the detached state.

  In order to achieve the above object, the lock deviation detecting method according to the present invention detects a deviation between a notch and a lock piece provided in the lock cane from a deviation amount of the lock cane with respect to the lock deviation detector. In the lock shift detection method to be performed, a step of setting an arbitrary threshold regarding the shift amount of the lock cane, a step of confirming a display indicating the shift amount or normal or abnormal, and if necessary, And a step of adjusting the position of the locking cane on-site by the amount of deviation continuously displayed as a numerical value. Hereinafter, “numeric display” and “continuous display” which are features of the lock deviation detection method of the present invention will be described.

(Numeric display)
With the above configuration, the shift of the lock cane is measured numerically in the maintenance work of the switch, and the shift generated by the position of the notch provided on the lock cane and the position of the lock piece is appropriate. Detected. Also, the measured shift of the lock cane is displayed as a numerical value. Conventionally, the adjustment work that a maintenance worker has performed while looking into the lock piece in the back of the machine can be achieved by confirming the deviation provided on the machine by numerical display. . Thereby, the workability | operativity of a lock cane shift adjustment is improved significantly. In addition, since the maintenance work conventionally performed by maintenance workers based on experience and intuition is performed by the deviation displayed by numerical values, the consistency of the quality of the maintenance work can be ensured.

(Continuous display)
Also, during the maintenance work of the turning machine, the shift of the lock cane is continuously measured, and the shift caused by the position of the notch provided on the lock cane and the position of the lock piece is always detected. it can. In addition, the measured shift of the lock cane is continuously displayed. Conventionally, the adjustment work that a maintenance worker has performed while looking into the lock piece in a deep place in the falling machine can be achieved by continuously checking the deviation provided in the falling machine. As a result, for example, when performing so-called offset adjustment in which the lock piece is adjusted by shifting from the center of the notch in accordance with the wrinkle of the turnout, not only the workability is improved, but also the experience of the maintenance worker This makes it possible to adjust the offset based on numerical values that are displayed continuously, rather than intuition, ensuring consistent quality of maintenance work.

  In addition, the lock shift detection method uses the shift lock position indicated by the numerical value to indicate the position of the lock lock when the switch requires a offset adjustment with respect to the shift lock shift. Preferably, an adjustment step is provided. Thus, when the offset adjustment is necessary, the adjustment can be easily and accurately performed using the shift of the lock cane continuously displayed as a numerical value.

  As described above, according to the lock deviation detector and the lock deviation detection method according to the present invention, the workability of the shifting adjustment of the lock can be improved in the field maintenance work, and the quality of the maintenance work is consistent. Thus, a lock deviation detector and a lock deviation detection method can be provided.

  Hereinafter, embodiments of the lock shift detector 1 according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of an embodiment of a lock shift detector 1 according to the present invention. FIG. 2 shows a method of measuring the shift amount in the lock shift detector 1. Further, FIG. 3 shows a method for detecting the shift of the lock can 14 based on the measurement of the shift amount in the lock shift detector 1. Here, the “deviation amount” means a means for expressing the movement amount represented by a numerical value, and the “deviation” is not only a movement amount represented by a numerical value, but also, for example, a chart, graph, color, It also includes means for expressing the amount of movement expressed by voice or the like.

  As shown in FIG. 8, the switch 30 includes a lock function that moves the lock cane 39 in conjunction with the operation of the tongrel 33 and maintains the state of the tongrel 33 at the end of the conversion operation. Therefore, as shown in FIG. 2, the lock piece 11 is inserted into the notch 12 provided in the lock can 14 to lock the movement of the lock can 14 and can be moved by being pulled out. Become. The lock piece 11 is preferably located at the center position of the notch 12. For example, the positions of the rails 32 and 33 and the turning machine 30 due to repeated train passage may be shifted, or the basic rail 32 and the Tonglel 33 may be When an abnormality such as a foreign object is caught between the notches 12, the notch 12 is displaced from the lock piece 11, and the lock of the lock lock 14 may not be completed. Therefore, the lock deviation detector 1 is provided with the linear sensor 2 in the detector case 10 and continuously measures the deviation amount of the lock cannula 14 by a numerical value. From the measurement result, the lock piece 11 and the notch 12 are measured. The deviation from the center position is detected and displayed.

(Components of lock deviation detector)
The lock shift detector 1 includes a measuring unit 3, a processing unit 4, and a display unit 9. The measuring unit 3 measures the shift amount of the lock can 14 with the linear sensor 2. The processing unit 4 includes a threshold value input unit 5, a detection unit 6, a storage unit 7, an output unit 25, and a determination unit 8. A threshold value (K) for the amount of shift of the lock can 14 is input to the threshold value input unit 5. Although the input threshold value (K) is stored in the storage unit 7, the detected deviation amount may also be stored in the storage unit 7. The detection unit 6 detects the positional relationship between the lock piece 11 and the notch 12 from the amount of shift of the lock can 14 measured by the measurement unit 3. The output unit 25 outputs the deviation amount, but the input threshold value (K) may be output. Furthermore, the display unit 9 is composed of a ratio display unit 9a and a shift display unit 9b, and displays the gap amount on both sides of the lock piece 11 or the ratio of the gap amounts numerically or, for example, a chart or graph, Alternatively, the shift is displayed by color or voice. Hereinafter, each component will be described in detail.

(Measurement function)
As shown in FIG. 2, the measurement unit 3 measures the amount of movement of the measurement piece 13 that is provided on the lock can 14 and moves by the linear sensor 2 connected to the detector case 10. In this embodiment, the linear sensor 2 is a plunger type sensor, and the amount of movement of the measuring piece 13 is measured by two sensors. However, other types of linear sensors 2 may be used, and the number of the linear sensors 2 may be two. Not exclusively. The pushing amount of the plunger causes a change in the output voltage, and the voltage is output to the processing unit 4. The processing unit 4 amplifies and converts the output.

  As shown in FIG. 2, the lock can 14 is connected to a connecting rod 19 and is connected to a pair of tongrels 15 a and 15 b via a connecting member 16. The connecting member 16 is provided with an adjusting screw 17 and adjusting nuts 18 provided on both sides of the adjusting screw 17. In order to adjust the position of the lock can 14, the adjustment nuts 18 on both sides are rotated to move the position of the adjustment screw 17.

  As shown in FIG. 3, the lock can 14 is provided with a lock mechanism using the lock piece 11 and the notch 12, and a deviation amount measuring means using the linear sensor 2 and the measurement piece 13. The lock mechanism and the shift amount measuring means are provided on the adjacent surfaces of the lock can 14 respectively. Among these, the linear sensor 2 is connected to the detector case 10. On the other hand, the notch 12 and the measurement piece 13 follow the movement of the lock can 14. Accordingly, when the lock can 14 is displaced by b in the direction indicated by the arrow in FIG. 3, the length (B) plunger becomes the length (B + b), and at the same time, the gaps on both sides of the lock piece 11 and the notch 12 are obtained. (M, n) is a gap (m + b, nb). Thus, the deviation amount in the lock mechanism by the lock piece 11 and the notch 12 can be measured by the deviation amount measuring means by the linear sensor 2 and the measurement piece 13.

(Function of threshold input unit)
The threshold value input unit 5 sets a threshold value (K) relating to the numerical value measured by the measuring unit 3 with respect to the positional relationship between the lock piece 11 and the center position of the notch 12. And the threshold value input part 5 of the lock shift detector 1 has a threshold value input means in which an arbitrary threshold value (K) can be set at the site of the switchboard. That is, the threshold (K) according to the present invention is an arbitrary threshold for the positional relationship between the lock piece 11 and the center position of the notch 12 by the threshold input means provided for each machine by the maintenance worker. (K) can be set. With this function, a maintenance worker sets a detailed value for each lock deviation detector 1, for example, a lock deviation detector 1 in which deviation is not a problem, and a lock deviation in which deviation is often a problem. Different threshold values (K) may be set for the detector 1. Moreover, since the maintenance worker can set the threshold value (K) at the site, a more realistic value can be set. Furthermore, for example, it is possible to set in consideration of seasonal weather conditions, or to set according to the years of use of the lock shift detector 1.

  The threshold value input unit 5 indicates a threshold value (K1) indicating that at least the numerical value of the deviation is an abnormal level, and a numerical value lower than the threshold value (K1) and indicating that the numerical value is a level to call attention. A threshold value (K2) can be set. That is, if a threshold value (K2) is provided before the point of detecting the shift abnormality of the lock shift detector 1, a warning alarm can be raised before the abnormality is detected. With this function, it is possible to treat a contact that has been switched between ON / OFF as normal or abnormal as a warning alarm that is intermittently switched and output. Further, the threshold value (K) set in the field is not limited to the threshold value (K1) and the threshold value (K2), and may be another threshold value (K), and the number of threshold values (K) is not limited to two. You can set any number. Furthermore, the numerical value of the threshold (K) can be arbitrarily set by the maintenance worker at the site.

(Threshold for offset adjustment)
When performing the offset adjustment according to the “に” of the branching device, a threshold value (K ′) reflecting the offset value is set. For example, for the threshold value (K ′) indicating that the numerical value of the deviation is an abnormal level, the ratio of the left and right gaps of the lock piece 11 in the notch 12 can be set as the threshold value (K ′). Further, a threshold value (K) may be set for each of the left and right gaps. Thus, the threshold value (K) can be set while confirming the display on the display unit 9.

(Detector function)
The detecting unit 6 detects the deviation of the notch 12 and the lock piece 11 provided in the locking cane 14 connected to the pair of tongrels 15, and the deviation of the locking cane 14 continuously measured by the measuring unit 3. Detect based on transition. Here, “detect” means not only expression means expressed numerically, such as the numerical values of the gaps on both sides of the notch 12 and the lock piece 11, the ratio of the numerical values of the gaps on both sides, For example, expression means represented by a chart, a graph, or color or voice is also included. That is, the detection unit 6 edits the numerical values continuously measured by the measurement unit 3 and transmits the data to the display unit 9 for display.

(Function of judgment unit)
Whether the determination unit 8 has the numerical values continuously measured by the measurement unit 3 exceeded a plurality of threshold values (K1, K2, K3...) Input to the threshold input unit 5 and stored in the storage unit 7, respectively. Determine whether or not. When the measured values exceed a plurality of threshold values (K) set by the threshold value input unit 5, other threshold values (K2, K3,...) Are set with respect to a certain threshold value (K1). A signal that can be identified as exceeding is transmitted to the display unit 9 each time. For example, a threshold value (K1) indicating that the numerical value of the deviation is an abnormal level and a threshold value (K2) indicating that the numerical value is lower than the threshold value and should be alerted are set. If the measured value exceeds the threshold value (K2), the display unit 9 is instructed to generate an intermittent buzzer sound. If the measured value exceeds the threshold value (K1), the continuous buzzer sounds. By instructing the display unit 9 to generate a sound, the maintenance worker can hear the caution alarm and the alarm audibly. Note that the display unit 9 may emit not only a buzzer sound but also other means such as voice, music, and color.

(Judgment adjustment judgment)
When performing the offset adjustment according to the “に” of the branching device, the determination unit 8 determines using a threshold value (K ′) reflecting the offset value. For example, when the measured value exceeds a threshold value (K′2) that is a level to call attention, for example, the display unit 9 is instructed to generate an intermittent buzzer sound, and the measured value is at an abnormal level. When a certain threshold value (K′1) is exceeded, for example, the display unit 9 is instructed to generate a continuous buzzer sound. For example, the ratio may be based on an unbalanced state of (6: 4). Further, the threshold value (K ′) may be changed on the left and right.

(Memory function)
The storage unit 7 stores the threshold (K) input by the threshold input unit 5 for each machine. Furthermore, you may memorize | store the deviation amount measured by the measurement part 3. FIG. As for the shift amount, data for a predetermined period may be stored and rewritten after output. Further, for the turning machine that performs the offset adjustment, a threshold value (K) that considers the offset adjustment may be stored.

(Function of output section)
The output unit 25 outputs the record of the threshold value (K) and the shift amount input by the field maintenance staff to each switch and outputs them to the switch monitor 26. Thereby, the field maintenance staff can confirm the record of the threshold value (K) inputted for every switch and the record of the deviation amount by the switch monitor 26. Then, the characteristics and habits of the branching device can be easily grasped by continuous numerical values. Furthermore, it is possible to easily determine the necessity of adjusting the offset of the turning machine.

(Display function)
The display unit 9 includes the ratio display unit 9a or the shift display unit 9b. However, the display unit 9 is not limited thereto, and may be displayed by other display means. The ratio display part 9a is a display means for displaying the numerical values of the gaps on both sides of the lock piece 11 and the notch 12 by the ratio. The shift display unit 9b is a display unit that displays the shift of the lock piece 11 with respect to the notch 12 by a numerical value or a figure or graph other than the numerical value, or a color or voice. In the present specification, an example of the ratio display unit 9a will be described. However, since the display portion of the shift display unit 9b is replaced by a graphic or graph representing a shift amount or shift instead of a ratio, description thereof is omitted.

  FIG. 4 is a block diagram showing functions relating to a shift amount detection method and its display method in the lock shift detector 1. FIG. 4A is a block diagram illustrating a relationship among the measurement unit 3, the detection unit 6, the output unit 25, the processing unit 4, and the display unit 9 illustrated in FIG. FIG. 4B is an explanatory diagram based on the shift amount measuring method in the lock shift detector 1 shown in FIG. The display unit 9 of the lock shift detector 1 has a meaning of indicating an assist point when the field maintenance staff adjusts the lock shift detector 1. That is, the on-site maintenance staff refers to the assist point and adjusts the positional relationship between the lock piece 11 and the notch 12 in the proper position. In this invention, as shown in FIG.4 (b), the method of measuring operation | movement of the measurement piece 13 attached to the lock canisters 14a and 14b with the voltage amount which generate | occur | produces in the plunger 54 of the linear sensor 2 is employ | adopted. . 4B, the tip of the plunger 54 moves according to the positional relationship between the lock piece 11 and the notch 12.

That is, with respect to the voltage amount (V ₀ ) when the plunger 54 is at the reference position, the voltage (V +) when the plunger 54 is extended and the plunger 54 are contracted, as indicated by reference numeral δ in FIG. The deviation amount can be estimated from the voltage (V−) in this case. As illustrated in FIG. 4A, the detection unit 6 acquires a voltage value (V) from the linear sensor 2. On the other hand, the detection unit 6 may acquire information from the linear sensor 2 that measures the stroke (extension amount) of the plunger 54, or may directly measure the left and right gaps of the lock piece 11 with an optical sensor. good.

  Then, the detection unit 6 transmits the voltage amount (V) to the conversion unit 53 and transmits the numerical value converted into the ratio of the left and right gaps of the lock piece 11 to the output unit 25. And the output part 25 transmits and displays the converted numerical value on the ratio display part 9a. Alternatively, the detection unit 6 transmits the voltage amount (V) to the output unit 25 without going through the conversion unit 53. The output unit 25 transmits the voltage value to the voltage display unit 9c as it is for display. The output unit 25 issues an alarm to the shift display unit 9b when a shift abnormality occurs.

(Ratio display)
FIG. 5 shows an example of ratio display which is one of the display methods of the display unit 9 of the lock deviation detector 1. FIG. 5A shows a screen of the switch machine monitor 26 which is an on-site display. FIG. 5B shows how the switch machine 11 is turned by the shift of the lock piece 11 with respect to the notch 12. Whether it is displayed on the screen of the monitor 26 is shown for each case.

  In FIG. 5A, a ratio display portion 9a is provided on the upper stage, which shows the numerical values of the gaps on both sides of the lock piece 11 and the notch 12 as a ratio. Conventionally, maintenance workers have measured the numerical values of the gaps on both sides of the lock piece 11 and the notch 12 and grasped the deviation amount by their ratio. Therefore, this display means can be said to be a display means that is easy for a maintenance worker to become familiar with. Conventionally, the maintenance worker opened the lid 24 of the tipping machine and looked into it, and calculated this ratio visually. According to the present invention, this ratio is not only accurately measured by the linear sensor 2, but also the maintenance worker can make a judgment based on the numerical values displayed continuously.

  In the lower stage, a change direction indicator 22 and a shift indicator 23 are provided. The change direction indicator 22 is provided with pilot lamps with LEDs on both the left and right sides of the drawing, and the pilot lamps in the changing direction are lit. In FIG. 5A, it can be seen that the lock piece 11 in the notch 12 has changed to the left because the left pilot lamp is lit as viewed in the drawing. In the deviation indicator 23, the LED illumination is turned on when the deviation amount is in the normal range, and the LED illumination is turned off when the deviation amount exceeds the threshold and becomes an abnormal range.

  The upper part of FIG. 5B shows a case where the left and right gaps of the lock piece 11 in the notch 12 are uniform. In this case, a ratio of (5: 5) is displayed on the screen of the switch monitor 26, the pilot indicator on the left side of the change direction indicator 22 as viewed in the drawing is lit, and the shift indicator 23 is in a normal state. ON display showing. 5B shows a case where the left and right clearances of the lock piece 11 in the notch 12 are unbalanced. In this case, a ratio of (4: 6) is displayed on the screen of the switch monitor 26, the pilot indicator on the left side of the change direction indicator 22 as viewed in the drawing is lit, and the shift indicator 23 is in a normal state. ON display showing. Furthermore, the lower part of FIG. 5B shows a case where the left and right gaps of the lock piece 11 in the notch 12 are abnormal. In this case, a ratio of (0: E) indicating an error is displayed on the screen of the switch machine monitor 26, the pilot lamp on the left side of the switch direction indicator 22 toward the drawing is lit, and the shift indicator 23 Becomes OFF display indicating an abnormal state. Then, a warning about deviation is issued.

(Voltage display)
FIG. 6 shows a display example in the case of voltage display, which is an embodiment for the display method of the display unit 9 of the lock deviation detector 1. FIG. 6A shows a screen of the switch machine monitor 51 which is an on-site display, and FIG. 6B shows how the machine is turned by the shift of the lock piece 11 with respect to the notch 12. Whether it is displayed on the screen of the monitor 51 is shown separately.

  In FIG. 6A, a voltage display portion 9c that shows the voltage value (V) as it is is provided in the upper stage. Here, for example, when the voltage value is 2.5 V, the decimal point is displayed as any numerical value, and in the case of the left side as viewed in FIG. 6, the display is divided into “5.” and “5”. 6 (a) -1 is displayed in the column, or in the case of the right side in FIG. 6, it is divided into “5” and “0.5”, and the two display columns in FIG. 6 (a) -2 are displayed. To display. Other display methods are based on the above-described “ratio display”. This display means can be said to be a display means familiar to the maintenance worker. Conventionally, maintenance workers have opened the lid 24 of the tipping machine and looked into it, and have confirmed this ratio visually. According to the present invention, this ratio is not only accurately measured by the linear sensor 2, but also an adjustment / maintenance worker can determine the degree of deviation based on the voltage value with which he / she is accustomed to handling.

  When the display unit 9 receives an abnormal signal from the determination unit 8, the display unit 9 issues an alarm that can be distinguished from when a certain threshold value (K) is exceeded and when another threshold value (K) is exceeded. When a threshold value (K1) indicating that the numerical value is an abnormal level and a threshold value (K2) indicating that the numerical value is lower than the threshold value and the numerical value is a level to call attention are set, for example, When the measured value exceeds the threshold value (K2), an intermittent buzzer sound is issued. When the measured value exceeds the threshold value (K1), a continuous buzzer sound is issued. Thereby, the maintenance worker can hear a warning alarm and an alarm audibly. Note that the display unit 9 may emit not only a buzzer sound but also other means such as voice, music, and color.

(Display of offset adjustment)
When performing the offset adjustment according to “癖” of the branching device 50, the display unit 9 reflects and displays the offset value. For example, when the unbalanced state in which the ratio is (6: 4) is used as the reference value, the threshold value (K) may be set apart from side to side. Moreover, in the ratio display part 9a of Fig.5 (a), it is preferable to display a measured ratio, a reference | standard ratio, and a threshold value so that a maintenance worker can judge easily, for example.

The output unit 25 of the lock shift detector 1 outputs the above-described threshold value and the measured shift amount to the detachable switchboard monitor 26 having the display unit 9. That is, the lock deviation detector 1 may remain attached to the lock deviation detector 1 as it is, or may be removed from the lock deviation detector 1. As a result, the turning device 30 can be adjusted at the site while reading information such as the threshold value and the measured deviation amount of the lock deviation detector 1. As a result, it has become possible for only one person who has been collaboratively working with two or more maintenance workers so far. Alternatively, the mobile terminal may be used as the switch monitor 26 and information to be transmitted from the output unit 25 to the switch monitor 26 may be transmitted. That is, the output unit 25 has a switch monitor with at least information displayed on the display unit 9 attached, a switch monitor with the information removed, or a switch monitor 26 as a portable terminal. Transmission terminal means for transmitting to the network.
Thereby, the maintenance worker does not need to carry the switch monitor 26 if he / she brings the portable terminal.

(How to adjust the lock deviation detector)
FIG. 7 is a flowchart showing the procedure of the method of adjusting the lock deviation detector according to the present invention. In this flowchart, each step is indicated by S1 to S8. Here, a lock deviation detection method for detecting the deviation between the notch 12 provided on the lock can 14 and the lock piece 11 from the deviation amount of the lock can 14 with respect to the lock deviation detector 1 will be described. First, as an initial value at the time of shipment, an arbitrary threshold value (K) relating to the amount of shift of the lock can 14 is set in the lock shift detector 1 (S1). Here, a plurality of arbitrary values can be set as the threshold (K). Then, it is determined whether or not the threshold value (K) has been set for all the lock deviation detectors 1 (S2). If “NO”, the process returns to step (S1). If “YES”, the process proceeds to the next step. Proceed (S3).

  Next, a numerical value indicating the shift amount between the lock piece 11 and the notch 12 or a display indicating whether the shift is normal or abnormal is confirmed (S3). In this way, the maintenance worker can confirm either one or both of the numerical value indicating the shift amount and the display indicating whether the shift is normal or abnormal for each lock shift detector 1. Next, from this confirmation result, it is determined whether or not the position adjustment or offset adjustment of the lock can 14 is necessary (S4). If it is determined that the position adjustment of the lock canister 14 or the offset adjustment is necessary, the process proceeds to the next step (S5), and it is determined that the position adjustment or the offset adjustment of the lock canister 14 is not required. If so, the process proceeds to step (S6).

  In steps (S6) and (S7), it is determined whether or not the threshold value set as the initial value in the lock deviation detector 1 is required (S6). A threshold value is set (S7). Then, it is determined whether or not the shift is adjusted for all the lock shift detectors. If NO, the process returns to S3, and if YES, the process ends (S8).

  The configuration, shape, size, and arrangement relationship described in the above embodiments are merely schematically shown to the extent that the present invention can be understood and implemented. Therefore, the present invention is not limited to the described embodiments, and can be variously modified without departing from the scope of the technical idea shown in the claims.
