Description

   The present invention relates to an apparatus for measuring a squareness (amount of right angle deviation) with respect to a sleeper track laid on a railroad track (track).

The sleeper laid on the track must be perpendicular to the track. For this reason, it is necessary to lay the sleeper so that the sleeper is perpendicular to the track when laying the railroad track, or to correct the right angle deviation of the sleeper with respect to the track along with aging. Therefore, when the railroad track is laid or afterwards, the perpendicularity of the sleeper with respect to the track is measured, and it is determined whether or not this perpendicularity is within a predetermined range.
The measurement of the perpendicularity of the conventional sleeper is performed by the method shown in FIG. FIG. 7 shows a case where the perpendicularity of the sleeper is measured using a right angle ruler (scoyer). In FIG. 7, when the sleepers 2 that are perpendicular to the pair of rails 1a and 1b laid in parallel are laid at a predetermined interval, the reference position of the sleeper 2 that is the target (the center line position in the figure) 1 and the other rail 1a and 1b are marked, and with reference to this mark, the skewer 3 is applied to the rail 1a, the skewer 3 is extended at right angles to the rail 1a, and the end of the skewer 3 bridged to the other rail 1b And the reference position marked with sleeper 2 on the other rail 1b side (deviation amount) is measured with a scale and recorded.

  As another method, there is a method of measuring the perpendicularity of the sleeper by using several types of triangle rulers in combination with the rails 1a and 1b.

  However, the squareness measurement according to the conventional technique has the following problems. In other words, when measuring the perpendicularity of one sleeper, about three people, such as the work of installing a scorer 3 or a triangle ruler on one rail 1a, the work of measuring on the other rail 1b, the work of recording the measurement results, etc. Personnel are required. Moreover, when performing each said operation | work, the measurement time of about 3 to 4 minutes per one sleeper is needed about alignment, measuring and recording. Furthermore, when reading the deviation amount on a scale, it is necessary to take a cramped posture in which the operator is bent, and labor is required for the measurement work. In this way, when measuring the perpendicularity of a conventional sleeper, there is a problem that it requires personnel, measurement time and labor, and the work efficiency is poor.

Furthermore, when measuring the perpendicularity of a sleeper, there is a problem that a measurement error in the measurement work of an operator, a type of instrument to be used, and a measurement error associated with the handling are likely to occur. In addition, there are many types of sleepers that are measurement targets, and there is a problem that measurement errors are likely to occur when the measurement position differs depending on the type. Furthermore, the measurement result is recorded on the form by the operator, and there is a problem that an entry error may occur. That is, when measuring the perpendicularity of a conventional sleeper, there is anxiety in measurement accuracy.
The present invention was invented in view of the above-described problems, and an object of the present invention is to provide a sleeper perpendicularity measuring apparatus that has good working efficiency and good measurement accuracy.

  The present invention that achieves the above-mentioned object is a device for measuring the perpendicularity of a sleeper laid at a right angle to a track, and a main body that can be bridged between a pair of parallel rails, A reference arm that is attached to one end of the main body and has a contact portion that contacts the longitudinal direction of one rail and determines the position of the main body relative to the rail by contacting the contact portion with the rail; and the reference arm A reference scale positioned at a measurement reference position along the longitudinal direction of the rail with respect to the arm and capable of contacting the measurement reference portion of the sleeper on the rail side, and a longitudinal direction of the other rail attached to the other end of the main body And a measuring arm on the other rail side corresponding to the measuring reference portion of the sleeper that is movable in the longitudinal direction with reference to the moving reference position of the measuring arm. And a detection means for obtaining the measurement site with respect to the movement reference position of the measurement rule, and connecting a line connecting the movement reference position of the measurement arm and the measurement reference position of the reference rule It is characterized in that it is perpendicular to the reference arm.

  According to the present invention, the perpendicular arm of the sleeper can be measured by bringing the reference arm into contact with one rail and bringing the reference rule into contact with the measurement reference part of the sleeper, and bringing the measurement rule into contact with the measurement part. One worker can measure immediately at once with one measuring instrument without taking an unreasonable posture, and work efficiency is improved, and the reference scale and measurement scale contact work to the measurement reference part and measurement part Therefore, even if different workers and sleeper types change, measurement errors hardly occur and measurement accuracy can be improved.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. Note that the same parts as those in FIG.
Embodiment
1 and 2 show a sleeper perpendicularity measuring apparatus according to this embodiment. FIG. 1 is a plan view and FIG. 2 is a side view. 1 and 2, the main body 10 has a length that can be bridged between a pair of parallel rails, and a reference arm 11 is attached to one end of the main body 10 so as to be perpendicular to the main body 10. ing. In this case, the main body 10 and the reference arm 11 are fixed by the fixed accessory arm 12 in order to ensure the perpendicularity and to ensure the fixation between the main body 10 and the reference arm 11.

  Two contact claws 13 which are contact portions with the rail are attached to the opposite side to the side where the main body 10 extends at both ends along the longitudinal direction of the reference arm 11. The abutment claw 13 has a horizontal claw 13a so as to abut on the upper end of the rail, and a vertical claw 13b extending vertically from the horizontal claw 13a so as to abut on the inner side surfaces of the rail (opposite side surfaces of the pair of rails). Have When the contact claw 13 is in contact with the rail, the longitudinal direction of the rail and the longitudinal direction of the reference arm 11 are parallel to each other, and the longitudinal direction of the rail and the main body 10 are perpendicular to each other. Although FIG. 1 shows an example in which two contact claws 13 are provided, the number and shape of the contact claws are in contact with each other in the longitudinal direction of the rail and the reference arm 11. There are no particular limitations as long as they are parallel to the longitudinal direction, and various ones are conceivable.

  Further, a reference scale 15 is arranged at a measurement reference position along the longitudinal direction of the rail with respect to the reference arm 11 (or the main body 10). In the example of FIGS. 1 and 2, the reference scale 15 is positioned on the reference arm 11 via the pedestal 14. In this case, the reference scale 15 is attached so as to be movable in the vertical direction (vertical direction) with respect to the pedestal 14 so as to be able to contact the measurement reference portion of the sleeper. That is, the vertical movement of the reference scale 15 can be adjusted to a height corresponding to the sleeper type. In this way, the reference scale 15 is attached so as to be able to come into contact with the measurement reference portion of the sleeper, for example, the side surface 31 of the band roll holder 30 shown in FIG. In this case, the measurement reference part of the sleeper can be variously set as long as the position in the sleeper is fixed. As an example, the band roll holder 30 is located in the sleeper and the position is fixed. Since it protrudes from the main body and easily comes into contact with the reference scale 15, it is used as a measurement reference site in this example. As a result, when the reference arm 11 is moved along the rail while the contact claw 13 is in contact with the rail, the reference scale 15 is brought into contact with the measurement reference portion of the sleeper. At this time, the measurement reference portion and the measurement reference position of the sleeper coincide with each other.

  A measuring arm 16 is attached to an end portion of the main body 10 opposite to an end portion on the reference arm 11 side of the main body 10 and at an inner portion of the other rail so as to form a right angle to the main body 10. In this case, the longitudinal direction of the measurement arm 16 is parallel to the longitudinal direction of the other rail. Further, a slide rail 17 is provided on the side surface of the measurement arm 16 in the longitudinal direction, and a base 18 is configured to be movable along the longitudinal direction with respect to the slide rail 17. Furthermore, since the measuring rule 19 is attached to the pedestal 18 so as to be movable in the vertical direction (vertical direction), like the reference rule 15, the height corresponding to the type of sleeper is adjusted by moving the measuring rule 19 in the vertical direction. be able to. The measurement ruler 19 is provided so as to be able to abut on the measurement part of the sleeper on the other rail side, for example, the side surface 31 of the band roll holder 30 shown in FIG. It will be. Here, the pedestal 18 and the measurement rule 19 that can move along the longitudinal direction on the slide rail 17 are opposed to the reference rule 15 at the measurement reference position of the reference arm 11 when the measurement arm 16 is at the movement reference position. The line connecting the movement reference position and the measurement reference position is perpendicular to the reference arm 11. In other words, the line connecting the movement reference position and the measurement reference position is perpendicular to the rail, the sleep measurement measurement part is present at the measurement reference position, and the sleep measurement part by the measuring rule 19 is present at the movement reference position. When present, the sleeper is perpendicular to the rail.

Therefore, in measuring the perpendicularity of the sleeper, the reference scale 15 is brought into contact with the measurement reference part of the sleeper on the reference arm 11 side so that the measurement reference position matches the measurement reference part, and the movement reference position on the measurement arm 16 side. On the other hand, the perpendicularity of the sleeper can be detected by measuring the position of the measuring rule 19 in contact with the measurement part of the sleeper. In the example of FIG. 1, the movement amount of the measuring rule 19 is set in a range of 50 mm on the left and right (up and down in the drawing) with the movement reference position as the center.
The amount of movement of the measuring rule 19 is detected by a detector as shown in FIG. 4, for example. In FIG. 4A, a plurality of holes 20 are formed in a row in the slide rail 17, and light is emitted from the light emitter 21 provided in the pedestal 18 to the holes 20, and the irradiated light is applied to the light receiver 22. The amount of movement from the movement reference position can be obtained by measuring a pulse that cannot receive light (or can receive light) due to the presence of the hole 20. 4B, the light passing through the hole 20 formed in one pulley 23 is counted by moving the endless belt 24 stretched between the pulleys 23 as the pedestal 18 moves on the slide rail 17. By doing so, the rotation amount of the pulley 23 and thus the movement amount of the pedestal 18 may be detected.

Then, on / off of the light detected by the light receiver 22 in FIGS. 4A and 4B is taken into the register 25 as a binary signal series as shown in FIG. Storage and display by the display 28 are performed.
The structure for obtaining the movement amount of the pedestal 18 may be a structure for obtaining the count value of a counter that rotates in accordance with the movement amount, regardless of whether the light is detected by the light receiver. As a simpler method, as shown in FIG. 4D, a scale 29 is formed on the measurement arm 16 along the slide arm 17 and the scale 29 is read as the pedestal 18 moves to detect the movement amount. You may make it do. However, in the case of FIG. 4D, it is necessary to write the value read from the scale 29 in a form or the like.

As a unit of movement amount of the pedestal 18, a unit that can measure to a minimum of 1 mm is preferable. Therefore, a hole (or a slit) formed in the slide rail 17 or the pulley 23 or a count value is formed at intervals that can be detected in 1 mm units. Or it is counted.
1 and 2, a battery (battery) box 4 serving as a power source of the electronic device shown in FIG. 4C is provided at the end of the main body 10 on the measurement arm 16 side, and further a power switch 5 of the electronic device. Is provided. Further, on the main body 10, for example, a display 28 that digitally displays the amount of movement of the measuring rule 19 relative to the movement reference position, a memory switch 6 that captures the display content of the display 28 into the memory 27 (not shown in FIG. 1), and a number of The sleeper specific information in the sleeper, which represents each sleeper as a measuring point, and the contents taken into the address display unit 7 and the memory 27 of the sleeper which collectively represents this measuring point (for example, 999 measuring points) as a group An operation switch 8 for shifting, erasing (clearing), and searching back and forth (up-down) is provided. In this way, it is possible to display the movement amount in the sleeper specified by the address display on the main body 10, store it, and move and recall the stored contents as necessary. As an electronic device on the main body 10, when the main object is to measure a number of sleepers one after another, the movement amount may be input to the memory 27 one after another without providing the display unit 28. good. In addition, since there are a lot of sleepers, only whether or not the perpendicularity is within the range is detected, and only when it is not within the range, it may be noted in the form. In this case, the movement amount of the measuring rule 16 is stored. It is also possible to provide only a display without providing a memory. Since the indicator 28 is measured in a tunnel or the like, display by a backlight is preferable, and illumination may be attached at the time of measurement in a dark place.

  In order to detect the movement amount of the measurement rule 19 in FIGS. 1 and 2 with reference to the movement reference position, it is necessary to set the initial position of the measurement rule 19 with respect to the movement reference position prior to measurement. In this case, for example, the pedestal 18 is moved to the end of the slide rail 17 and the position of the end is reset as the origin of the end with respect to the movement reference position (for example, a reset switch (not shown) is pressed or the like) to perform initial setting. May be. Alternatively, when the main body 10 forms a right angle with respect to the reference arm 11 and the measurement arm 16 forms a right angle with respect to the main body 10, the movement reference to the measurement arm 16 is opposed to the measurement reference position of the reference scale 15. The position may be stamped, and the measuring rule 19 may be aligned with the stamp.

  5 and 6 show a state in which the perpendicularity of the sleeper is measured. 5 and 6, when measuring the squareness of the sleeper 2 to be measured laid on the left and right rails 1a and 1b forming the track, the present embodiment is used between the left and right rails 1a and 1b. Put the body of the sleeper perpendicularity measuring device. The contact claw 13 attached to the reference arm 11 is brought into contact with one rail 1a and the reference arm 11 is moved along the rail to move the reference measure 15 to the side surface 31 of the band roll holder 30 of the sleeper 2. Contact the measurement reference part. Next, on condition that the power switch 5 (see FIG. 1) is turned on, the pedestal 18 of the measuring rule 19 is moved to the end of the slide rail 17 along the other rail 1b to reset and perform the initial setting. Thereafter, the pedestal 18 is moved on the slide rail 17, and the measurement rule 19 is brought into contact with the measurement site which is the side surface 31 of the band roll holder 30. By this contact, the amount of movement of the measuring rule 19 between the movement reference position and the position contacting the measurement site can be measured, and the value can be displayed on the display and stored in the memory.

As described above, the sleeper perpendicularity measuring apparatus according to the present embodiment has an unreasonable posture such as abutting the contact claw 13, the reference rule 15, and the measurement rule 18 by a single operator with a single measuring device. It is possible to measure the squareness with respect to the rail in a simple and short work without using it, and because it is based on measurement by confirming contact, there is also a measurement error that depends on the measurer Hard to occur. Then, by connecting the CPU 26 shown in FIG. 4C to a personal computer or a printer, it is possible to process measurement values and print on paper.
The contact portion with the rail or the band roll of the sleeper perpendicularity measuring device is formed of an insulating resin to prevent a short circuit or a bridging. Here, the contact claw 13 and the reference scale 15 are formed. The measuring rule 19 is formed of an insulating resin, and the insulating plate 9 is disposed at the end of the main body 10 in contact with the rail 1b.

  The sleeper perpendicularity measuring device in this embodiment is formed so that the reference arm 11 and the measurement arm 16 form a right angle with respect to the main body 10 for manufacturing purposes, but the configuration that forms this right angle is not necessarily strict. The reference arm 11 is parallel to the rail, the measurement reference position of the reference rule 15 and the measurement arm 16 position reference position are opposed, and the base 18 and the measurement rule 19 that move the slide rail 17 of the measurement arm 16 are in the longitudinal direction of the rail. If the structure is movable, the perpendicularity of the sleeper can be measured.
