Description

  The present invention relates to a display of a lock deviation amount by a lock deviation amount detector of a turning machine.

  As a turning machine, a machine equipped with an operation cane and a lock cane is generally employed. Such a switch is installed on the left or right side of the rail on which the branching device is installed, and has a mechanism in which the operating cannula and the locking cane are respectively connected to the tongler of the branching unit. The lock piece is moved from the side into the notch of the lock cane that moves with the tongue, and the lock cannot be operated, and thus the lock is completed. The notch and the lock piece are provided corresponding to each of the orientation and the inversion. The turning machine moves the two lock pieces back and forth alternately in the direction intersecting the lock canister, and inserts and removes them from each notch by moving back and forth alternately.

When the lock is completed, there is a gap between the notch of the lock and the lock piece, and the position adjusted by evenly arranging the gap on the left and right of the lock piece is the 0 point (center). This amount of movement with respect to the zero point is referred to as a lock deviation amount.
Since the lock cane is mechanically connected to the Tongrel, the lock can also be moved by movement, expansion and contraction, friction, etc. of the rail. This movement leads to a change in the relative position of the notch of the lock cane and the lock piece.
If the relative position of the notch of the lock and the lock piece shifts, the lock piece cannot be inserted into the notch even if the movement to the normal position or the inverted position has been completed correctly. Unable to complete the lock. If the lock cannot be completed, the train cannot pass.
For this reason, the switch is provided with a lock deviation amount detector, which is useful for maintenance and inspection by displaying the deviation between the notch and the lock piece.
Patent Document 1 describes an invention relating to a detection method using a lock deviation amount detector. This document describes that the left and right clearances of the lock piece are displayed as values.

Conventionally, as a lock deviation amount detector of a switch, a device that displays a plurality of threshold values for the lock deviation amount and visualizes them in correspondence with combinations of LED colors and lighting arrangements in each range divided by the threshold values. It's being used. By referring to such a display, it is possible to know the lock shift state divided in stages. A range corresponding to “re-adjustment required” and its display are also provided. A plurality of threshold values are also provided in an area closer to 0 point than the threshold value that delimits “re-adjustment required”.
Therefore, the inspector can know the lock shift state even if the notch and the lock piece are not visually recognized by looking at the LED display, and can determine whether or not readjustment is necessary. In addition, when adjusting the lock, the operator can determine the proximity to the zero point by referring to the LED display. That is, the lock deviation amount detector can assist the adjustment of the lock position. Then, the range closest to the zero point is set as the adjustment completion range within this range, and the adjustment is completed.

However, the above-described conventional technology has the following problems.
Even if the adjustment is completed within the adjustment completion range that is closest to the zero point, if the adjustment is made to the position farthest from the zero point within that range, it is close to the “re-adjustment required” range, so the subsequent conversion Or a slight shift of the rails due to the passing of the train, it immediately entered the range of “re-adjustment required”. It was forced to readjust.
On the other hand, if the adjustment completion range is set narrow, the adjustment accuracy required becomes strict, the adjustment work becomes difficult, and the adjustment time may be extended uniformly.

  The present invention has been made in view of the above problems in the prior art, and is capable of display corresponding to a narrow range closer to 0 point while maintaining the conventional step display function of the lock deviation amount. It is an object of the present invention to provide a lock deviation amount detector for an iron machine.

The invention described in claim 1 for solving the above-described problems is a lock deviation amount detector for a turning machine provided with a display for displaying the detected lock deviation amounts in a plurality of ranges in stages. And
A range including a zero point of the locking shift amount among the plurality of ranges, possess a relatively broad range, the display mode switching means for switching to a relatively narrow range,
An opening / closing lid of a handle insertion port for inserting a handle for manually driving the switch is used as the switching operation means of the display mode switching means, and the display mode switching means is relatively wide when the opening / closing lid is closed. It is a lock deviation amount detector for a switch that switches to a range and switches to the relatively narrow range when the opening / closing lid is opened .

According to the present invention, the range closest to the zero point of the lock deviation amount, that is, the range including the zero point of the lock deviation amount can be switched between a relatively wide range and a relatively narrow range. By switching to a display in a relatively narrow range according to the user's selection, it is possible to support adjustment to near zero with higher accuracy and to perform adjustment work by switching to a display in a relatively wide range. There is an effect that it is possible to select the ease.
Also, it is necessary to provide a switching operation means specially for the introduction of the present invention by using the opening / closing lid of the handle insertion port for inserting the handle for manually driving the switch as the switching operation means of the display mode switching means. Since there is no effect, and since the opening / closing lid is always closed after adjustment, there is an effect that it is possible to prevent forgetting to switch back.

It is the figure which showed the relationship between the amount of lock | rock deviation by the lock | rock deviation | shift amount detector of the switch and the display which concerns on one Embodiment of this invention, and a display. However, the lock deviation amount is expressed as an effective number up to the first decimal place. It is a block diagram which shows the main electrical equipment parts of the switchboard which concerns on one Embodiment of this invention. It is the schematic diagram which showed the opening / closing state of the opening-and-closing lid | cover of the handle insertion opening of the switch machine which concerns on one Embodiment of this invention, and ON / OFF of the switch corresponding to this.

  An embodiment of the present invention will be described below with reference to the drawings. The following is one embodiment of the present invention and does not limit the present invention.

  As shown in FIG. 1, when the lock is completed, the lock piece I is inserted into the notch H of the lock can. The distance between the locking cane line G1 and the gauge line G2 corresponds to the lock deviation amount. When the locking cane line G1 and the gauge line G2 coincide with each other, the lock deviation amount is 0, and the lock piece I is located at the exact center of the notch H. A state E0 in FIG. 1 indicates this state. States E1R to E4R indicate a state where the notch H is unevenly distributed to the right with respect to the lock piece I, and states E1L to E4L indicate a state where the notch H is unevenly distributed to the left with respect to the lock piece I. F0, F1R to F4R, and F1L to F4L are LED display modes corresponding to each range. In FIG. 1, coordinates are shown with the shift to the left of the notch H as minus, and LED display forms corresponding to each range are shown.

As shown in FIG. 2, the lock deviation amount detector includes a control unit 10, a sensor 11, and an LED display 12. The control unit 10 is connected to the sensor 11 and the LED indicator 12, and is connected to the changeover switch 15 a via the switch detection circuit 13. In addition, the switch body includes a motor 14, a power circuit 16 for the motor 14, and a power cut-off switch 15b. The motor 14 is connected to a drive circuit, a control circuit, and a power source via the power circuit 16.
The position of the gauge line G2 is sensed by the sensor 11 provided in the lock deviation amount detector, and the control unit 10 calculates the lock deviation amount based on the sensed signal and displays it according to each range shown in FIG. Is displayed on the LED display 12. The LED display 12 is provided with three LEDs P1, P2, and P3.

When the contact point 1-2 of the changeover switch 15a is conductive (ON), the control unit 10 has a lock deviation amount in a range B of ± 0.3 mm from the 0 point as in the state E0 in FIG. The three LEDs P1, P2, and P3 of the LED display 12 are all lit in green.
When the amount of lock deviation is in the range CR as in the state E1R in FIG. 1, the control unit 10 turns off the LED P3 of the LED display 12 and turns on the LEDs P1 and P2 in green.
When the amount of lock deviation is in the range CL as in the state E1L in FIG. 1, the control unit 10 turns off the LEDP1 of the LED display 12 and turns on the LEDs P2 and P3 in green.
The display forms corresponding to the other ranges are as shown in FIG.
In the range DR and range DL, as the indication of “re-adjustment required”, the former LEDP2 and P3 are turned off, the LEDP1 is lit orange, the latter LEDP1 and P2 are turned off, and the LEDP3 is lit orange.

  On the other hand, when the contact point 1-2 of the changeover switch 15a is non-conductive (off), the control unit 10 has a lock deviation amount in a range A of ± 0.1 mm from the 0 point as in the state E0S in FIG. At a certain time, the three LEDs P1, P2, and P3 of the LED indicator 12 are all blinked in green.

  A handle insertion port 18 as shown in FIG. 3 is formed on the upper surface of the casing of the switch machine body so as to be located above the conversion mechanism, and an opening / closing lid 17 corresponding to the handle insertion port 18 is formed. Is attached. The opening / closing lid 17 is attached to the upper surface of the casing of the tumble machine main body so as to be rotatable in the horizontal direction. The opening / closing lid 17 has a closed position for closing the handle insertion port 18 and an open position for opening the handle insertion opening 18. Displace between.

  When the opening / closing lid 17 is opened and the handle insertion port 18 is opened, the handle insertion port 18 can be inserted with the tip of the handle for manually driving the conversion mechanism. When the distal end portion of the handle is inserted into the handle insertion port 18, the distal end portion is connected to the manual mechanism of the conversion mechanism, and when the handle is rotated, the operation mechanism is operated by the manual mechanism. Further, the opening / closing lid 17 is connected to the switch unit 15, and the changeover switch 15a and the power cut-off switch 15b are switched on / off according to the rotation angle of the opening / closing lid 17, as shown in FIG.

  FIG. 3 shows the relationship between the open / close position (rotation angle) of the open / close lid 17 and the on / off switching of the switch unit 15.

  The open / close lid 17 includes a disc-shaped lid main body 17a and a connecting portion 17b protruding from the outer peripheral portion of the lid main body 17a, and the connecting portion 17b is pivotally supported to be rotatable in the horizontal direction. . The switch unit 15 is connected to the connecting portion 17b of the opening / closing lid 17, and the changeover switch 15a and the power cut-off switch 15b are operated when the opening / closing lid 17 is rotated in the opening direction from the closed position (FIG. 3 (a)). When the opening / closing lid 17 is turned from the open position to the closing direction, the switch is switched from off to on.

  According to the above-described lock deviation amount detector of the present embodiment, when the open / close lid 17 is closed, the same lock deviation amount display as in the prior art is displayed. When the open / close lid 17 is open, the lock deviation amount detector is the most locked. A range near the zero point of the shift amount becomes a range A narrower than the conventional range B, and a lock shift amount display for specifying a limited range closer to the zero point is made.

  Therefore, an adjuster who adjusts the amount of lock deviation opens the opening / closing lid 17, inserts the handle into the handle insertion port 18, and operates this handle to lock the machine in a fixed position or inverted position. Next, the relative position of the notch H and the lock piece I is adjusted by operating an adjusting mechanism using a screw mechanism provided in the lock rod or the front rod. At this time, since the open / close lid 17 is open, the range closest to the zero point of the lock deviation amount is displayed as a relatively narrow range A and all blinks F0S are displayed. Therefore, compared to the case where the full lighting F0 is displayed in the relatively wide range B as the range closest to the zero point of the lock deviation amount, it is possible to support the adjustment to the near zero point with higher accuracy. it can.

  When the adjuster puts the lock deviation amount in the range A and finishes the adjustment, the adjuster fixes the adjustment mechanism by fastening the lock nut of the adjustment mechanism, removes the handle from the handle insertion port 18, and closes the opening / closing lid 17. At this time, since the fixing position of the notch H by the adjusting mechanism is slightly shifted by the operation of fastening the lock nut of the adjusting mechanism, the lock deviation amount may slightly deviate from the range A. However, even in this case, the adjustment is completed if the display of full lighting F0 is obtained when the open / close lid 17 is closed. Even in this case, since the amount of lock deviation after the adjustment is not in the vicinity of the threshold value (0.3 mm) of the range B but in the vicinity of the threshold value (0.1 mm) of the range A, the adjustment is completed at a position closer to the 0 point than in the past. Secured.
