Description

本発明は、レール摩耗量測定器に関する。   The present invention relates to a rail wear amount measuring device.

天井クレーンのガーダは建屋の側壁に敷設されたレールに沿って走行する。クレーンを安全に使用するため、定期的にレールの頭頂面および頭部側面の摩耗量を測定し、レールの状態を確認する必要がある。   The overhead crane girder runs along rails laid on the side walls of the building. In order to use the crane safely, it is necessary to regularly measure the amount of wear on the top and side surfaces of the rail to check the state of the rail.

従来、レールの摩耗量の測定は汎用の鋼尺やノギスを用いて行っていた。そのため、鋼尺の配置の仕方によっては摩耗量を正確に測定できないことがある。また、測定作業に複数の人員を要し、時間を要する。そこで、レールの摩耗量の測定に用いられる専用の器具が考案されている。   Conventionally, the amount of wear of the rail has been measured using a general-purpose steel ruler or caliper. Therefore, the amount of wear may not be accurately measured depending on the arrangement of the steel rule. In addition, the measurement work requires a plurality of personnel and takes time. Therefore, a dedicated instrument used for measuring the amount of wear of the rail has been devised.

特許文献１には、レールの頭頂面と頭部側面とに当接する当接部材を有する測定器が開示されている。当接部材によりレールに対して測定器を位置決めした状態で、摩耗量の測定を行なう。   Patent Document 1 discloses a measuring instrument having an abutting member that abuts on the top surface and the side surface of the head of a rail. The wear amount is measured in a state where the measuring device is positioned with respect to the rail by the contact member.

特許文献２には、レールの頭部アゴ下部と頭部側面とに当接する基準部を有する定規が開示されている。基準部によりレールに対して定規を位置決めした状態で、摩耗量の測定を行なう。   Patent Document 2 discloses a ruler having a reference portion that comes into contact with the lower portion of the head portion of the rail and the side surface of the head portion. The amount of wear is measured with the ruler positioned with respect to the rail by the reference portion.

〔第１実施形態〕
（レール）
本発明の第１実施形態に係るレール摩耗量測定器１は、図７に示すようなレール１００を測定対象とする。このレール１００は、一般に平底レールと称されるものであり、底部１１０と、底部１１０に立設する腹部１２０と、腹部１２０の上端に設けられた頭部１３０とからなる。 Next, an embodiment of the present invention will be described with reference to the drawings.
[First Embodiment]
(rail)
The rail wear amount measuring instrument 1 according to the first embodiment of the present invention uses a rail 100 as shown in FIG. The rail 100 is generally referred to as a flat bottom rail, and includes a bottom 110, an abdomen 120 standing on the bottom 110, and a head 130 provided at the upper end of the abdomen 120.

底部１１０の底面、側面、上面を、それぞれ底部底面１１１、底部側面１１２、底部上面１１３と称する。腹部１２０の側面を腹部側面１２１と称する。頭部１３０の上面、側面を、それぞれ頭頂面１３１、頭部側面１３２と称する。   The bottom surface, side surface, and top surface of the bottom portion 110 are referred to as a bottom surface 111, a bottom surface 112, and a bottom surface 113, respectively. The side surface of the abdomen 120 is referred to as the abdomen side surface 121. The upper surface and side surfaces of the head 130 are referred to as a top surface 131 and a head side surface 132, respectively.

頭頂面１３１には車輪の踏面が接触する。また、頭部側面１３２には車輪のフランジが接触する。したがって、頭頂面１３１および頭部側面１３２は車輪との接触により摩耗する。一方、底部１１０および腹部１２０には車輪が接触しないので、基本的にこれらが摩耗することはない。   The tread surface 131 is in contact with the tread surface 131. Further, a wheel flange contacts the head side surface 132. Therefore, the top surface 131 and the head side surface 132 are worn by contact with the wheels. On the other hand, since the wheel does not contact the bottom 110 and the abdomen 120, they are not basically worn.

本明細書では、底部底面１１１を水平面上に設置した状態を基準として、レール１００の幅方向（図７におけるｘ方向）を横方向、レール１００の高さ方向（図７におけるｙ方向）を縦方向とする。また、図７におけるｚ方向がレール１００の長手方向である。   In this specification, the width direction (x direction in FIG. 7) of the rail 100 is the horizontal direction and the height direction (y direction in FIG. 7) of the rail 100 is the vertical direction with reference to the state where the bottom bottom surface 111 is installed on the horizontal plane. The direction. Further, the z direction in FIG. 7 is the longitudinal direction of the rail 100.

（レール摩耗量測定器）
図１、図２、図３に示すように、本実施形態のレール摩耗量測定器１は、厚みのある板材を所定の形状に加工して形成されたものである。レール摩耗量測定器１は、レール１００に当接する基準部１０と、基準部１０の上部に接続し縦方向に延びる縦部２０と、縦部２０の上端部に接続し横方向に延びる横部３０とからなる。 (Rail wear meter)
As shown in FIGS. 1, 2, and 3, the rail wear amount measuring device 1 according to the present embodiment is formed by processing a thick plate material into a predetermined shape. The rail wear amount measuring instrument 1 includes a reference portion 10 that contacts the rail 100, a vertical portion 20 that is connected to the upper portion of the reference portion 10 and extends in the vertical direction, and a horizontal portion that is connected to the upper end portion of the vertical portion 20 and extends in the horizontal direction. 30.

基準部１０はその外周面がレール１００の底部上面１１３と腹部側面１２１とに当接する。基準部１０の外周面のうち底部上面１１３に当接する面を第１当接面１１、腹部側面１２１に当接する面を第２当接面１２と称する。基準部１０を底部上面１１３と腹部側面１２１とに当接させることで、レール摩耗量測定器１をレール１００に対して位置決めできる。詳しくは、基準部１０を底部上面１１３に当接させることで、レール摩耗量測定器１の縦方向の位置を位置決めできる。基準部１０を腹部側面１２１に当接させることで、レール摩耗量測定器１の横方向の位置を位置決めできる。   The outer peripheral surface of the reference portion 10 abuts on the bottom upper surface 113 and the abdominal side surface 121 of the rail 100. Of the outer peripheral surface of the reference portion 10, a surface that contacts the bottom upper surface 113 is referred to as a first contact surface 11, and a surface that contacts the abdomen side surface 121 is referred to as a second contact surface 12. The rail wear amount measuring instrument 1 can be positioned with respect to the rail 100 by bringing the reference portion 10 into contact with the bottom upper surface 113 and the abdomen side surface 121. Specifically, the vertical position of the rail wear amount measuring instrument 1 can be positioned by bringing the reference portion 10 into contact with the bottom upper surface 113. By bringing the reference portion 10 into contact with the abdomen side surface 121, the lateral position of the rail wear amount measuring instrument 1 can be determined.

レール摩耗量測定器１をレール１００に対して位置決めした状態（基準部１０をレール１００に当接させた状態）とすると、縦部２０はレール１００の側方に位置し、横部３０はレール１００の上方に位置する。すなわち、レール摩耗量測定器１は全体として、レール１００の片側側方および上方を囲う形状を有している。   When the rail wear amount measuring instrument 1 is positioned with respect to the rail 100 (the reference portion 10 is in contact with the rail 100), the vertical portion 20 is positioned on the side of the rail 100, and the horizontal portion 30 is the rail. Located above 100. That is, the rail wear amount measuring instrument 1 as a whole has a shape surrounding one side of the rail 100 and the upper side.

縦部２０の頭部１３０に対向する縦方向位置には、縦部２０の表面に横方向に沿った横溝２１が形成されている。また、横部３０の頭部１３０に対向する横方向位置には、横部３０の表面に縦方向に沿った縦溝３１が形成されている。横溝２１はレール１００の底部底面１１１と平行に頭部１３０へ向けて配置されており、縦溝３１はレール１００の底部底面１１１に対して垂直に頭部１３０へ向けて配置されている。   A lateral groove 21 along the lateral direction is formed on the surface of the longitudinal portion 20 at a longitudinal position facing the head portion 130 of the longitudinal portion 20. Further, a vertical groove 31 along the vertical direction is formed on the surface of the horizontal portion 30 at a horizontal position facing the head portion 130 of the horizontal portion 30. The lateral grooves 21 are arranged toward the head 130 in parallel with the bottom bottom surface 111 of the rail 100, and the vertical grooves 31 are arranged toward the head 130 perpendicular to the bottom bottom surface 111 of the rail 100.

（測定方法）
レール摩耗量測定器１を用いたレール１００の摩耗量の測定は以下の手順で行なう。
図４に示すように、まず、基準部１０をレール１００の底部上面１１３と腹部側面１２１とに当接させて、レール摩耗量測定器１をレール１００に対して位置決めする。 (Measuring method)
The measurement of the wear amount of the rail 100 using the rail wear amount measuring device 1 is performed according to the following procedure.
As shown in FIG. 4, first, the reference portion 10 is brought into contact with the bottom upper surface 113 and the abdomen side surface 121 of the rail 100 to position the rail wear amount measuring instrument 1 with respect to the rail 100.

前述のごとく、レール１００の底部１１０および腹部１２０が摩耗することはない。摩耗が生じない底部上面１１３と腹部側面１２１とを基準とすることで、レール摩耗量測定器１を常に一定の位置に位置決めできる。例えば、レール摩耗量測定器１がレール１００に対して傾いて設置されることがない。そのため、摩耗量を正確に測定できる。   As described above, the bottom 110 and the abdomen 120 of the rail 100 are not worn. By using the bottom upper surface 113 and the abdominal side surface 121 where no wear occurs as a reference, the rail wear amount measuring instrument 1 can always be positioned at a fixed position. For example, the rail wear amount measuring instrument 1 is not installed inclined with respect to the rail 100. Therefore, the wear amount can be accurately measured.

つぎに、横部３０に形成された縦溝３１に鋼尺などの直尺４０を嵌める。直尺４０は縦溝３１に沿って摺動自在となっている。換言すれば、縦溝３１は直尺４０が摺動自在に嵌められるよう形成されている。具体的には、縦溝３１の幅は直尺４０の幅と同じかこの幅よりも若干広く設定されている。   Next, a straight ruler 40 such as a steel ruler is fitted into the vertical groove 31 formed in the horizontal part 30. The straight scale 40 is slidable along the longitudinal groove 31. In other words, the vertical groove 31 is formed so that the straight scale 40 is slidably fitted. Specifically, the width of the vertical groove 31 is set to be the same as or slightly wider than the width of the straight scale 40.

直尺４０を縦溝３１に沿って摺動させて、直尺４０の先端をレール１００の頭頂面１３１に接触させる。この状態で直尺４０により横部３０と頭頂面１３１との距離Ｄ１を測定する。予め、摩耗していないレール１００を用いて距離Ｄ１を測定してこれを基準値としておく。測定により得られた距離Ｄ１と基準値との差から、頭頂面１３１の摩耗量を求める。   The straight scale 40 is slid along the longitudinal groove 31, and the tip of the straight scale 40 is brought into contact with the top surface 131 of the rail 100. In this state, the distance D1 between the horizontal portion 30 and the parietal surface 131 is measured with the straight scale 40. The distance D1 is measured in advance using the rail 100 that is not worn, and this is set as a reference value. From the difference between the distance D1 obtained by the measurement and the reference value, the wear amount of the parietal surface 131 is obtained.

つぎに、縦部２０に形成された横溝２１に直尺４０を嵌める。直尺４０は横溝２１に沿って摺動自在となっている。換言すれば、横溝２１は直尺４０が摺動自在に嵌められるよう形成されている。具体的には、横溝２１の幅は直尺４０の幅と同じかこの幅よりも若干広く設定されている。   Next, the straight scale 40 is fitted into the lateral groove 21 formed in the vertical portion 20. The straight scale 40 is slidable along the lateral groove 21. In other words, the lateral groove 21 is formed so that the straight scale 40 is slidably fitted. Specifically, the width of the lateral groove 21 is set to be the same as or slightly wider than the width of the straight scale 40.

直尺４０を横溝２１に沿って摺動させて、直尺４０の先端をレール１００の頭部側面１３２に接触させる。この状態で直尺４０により縦部２０と頭部側面１３２との距離Ｄ２を測定する。予め、摩耗していないレール１００を用いて距離Ｄ２を測定してこれを基準値としておく。測定により得られた距離Ｄ２と基準値との差から、頭部側面１３２の摩耗量を求める。なお、常に頭部側面１３２の同一高さにおける摩耗量を測定できる。   The straight scale 40 is slid along the lateral groove 21, and the tip of the straight scale 40 is brought into contact with the head side surface 132 of the rail 100. In this state, the distance D <b> 2 between the vertical portion 20 and the head side surface 132 is measured with the straight scale 40. The distance D2 is measured in advance using the rail 100 that is not worn, and this is set as a reference value. From the difference between the distance D2 obtained by the measurement and the reference value, the wear amount of the head side surface 132 is obtained. Note that the wear amount at the same height of the head side surface 132 can always be measured.

なお、摩耗していないレール１００にレール摩耗量測定器１を設置した場合に、横部３０が頭頂面１３１に接する構成としてもよいし、横部３０が頭頂面１３１から離間する構成としてもよい。横部３０が頭頂面１３１に接する構成とすれば、横部３０と頭頂面１３１との間の隙間の有無により、頭頂面１３１が摩耗しているか否かをすぐに判断できる。   When the rail wear amount measuring device 1 is installed on the rail 100 that is not worn, the lateral portion 30 may be in contact with the parietal surface 131, or the lateral portion 30 may be separated from the parietal surface 131. . If the horizontal portion 30 is in contact with the parietal surface 131, whether or not the parietal surface 131 is worn can be immediately determined by the presence or absence of a gap between the horizontal portion 30 and the parietal surface 131.

同様に、摩耗していないレール１００にレール摩耗量測定器１を設置した場合に、縦部２０が頭部側面１３２に接する構成としてもよいし、縦部２０が頭部側面１３２から離間する構成としてもよい。縦部２０が頭部側面１３２に接する構成とすれば、縦部２０と頭部側面１３２との間の隙間の有無により、頭部側面１３２が摩耗しているか否かをすぐに判断できる。   Similarly, when the rail wear amount measuring instrument 1 is installed on the non-wearing rail 100, the vertical portion 20 may be in contact with the head side surface 132, or the vertical portion 20 may be separated from the head side surface 132. It is good. If the vertical portion 20 is in contact with the head side surface 132, whether or not the head side surface 132 is worn can be immediately determined based on the presence or absence of a gap between the vertical portion 20 and the head side surface 132.

図１に示す例では、横部３０が頭頂面１３１に接触する構成であり、縦部２０が頭部側面１３２から離間する構成である。図４に示すように、頭頂面１３１が摩耗している場合、横部３０と頭頂面１３１との間に隙間が形成されるので、頭頂面１３１が摩耗していることをすぐに判断できる。   In the example illustrated in FIG. 1, the horizontal portion 30 is in contact with the top surface 131 and the vertical portion 20 is spaced from the head side surface 132. As shown in FIG. 4, when the parietal surface 131 is worn, a gap is formed between the lateral portion 30 and the parietal surface 131, so it can be immediately determined that the parietal surface 131 is worn.

以上のように、本実施形態のレール摩耗量測定器１を用いれば、レール１００の頭頂面１３１および頭部側面１３２の摩耗量を正確に測定できる。また、汎用の鋼尺やノギスを用いる場合に比べて操作が容易であり、作業員が１人で測定できるし、測定に要する時間も短縮できる。また、特殊な距離計などの装置を必要としないので、安価である。   As described above, by using the rail wear amount measuring instrument 1 of the present embodiment, the wear amounts of the top surface 131 and the head side surface 132 of the rail 100 can be accurately measured. In addition, operation is easier than in the case of using a general-purpose steel ruler or vernier caliper, the operator can perform measurement alone, and the time required for measurement can be shortened. In addition, since a special distance meter or the like is not required, it is inexpensive.

〔第２実施形態〕
つぎに、本発明の第２実施形態に係るレール摩耗量測定器２を説明する。
図５に示すように、本実施形態のレール摩耗量測定器２は、第１実施形態のレール摩耗量測定器１において基準部１０の形状を変更したものである。その余の構成は第１実施形態のレール摩耗量測定器１と同様であるので、同一部材に同一符号を付して説明を省略する。 [Second Embodiment]
Next, the rail wear amount measuring device 2 according to the second embodiment of the present invention will be described.
As shown in FIG. 5, the rail wear amount measuring device 2 of the present embodiment is obtained by changing the shape of the reference portion 10 in the rail wear amount measuring device 1 of the first embodiment. Since the rest of the configuration is the same as that of the rail wear amount measuring instrument 1 of the first embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted.

本実施形態の基準部１０はその外周面がレール１００の底部上面１１３と底部側面１１２とに当接する。基準部１０の外周面のうち底部上面１１３に当接する面を第１当接面１１、底部側面１１２に当接する面を第３当接面１３と称する。基準部１０を底部上面１１３と底部側面１１２とに当接させることで、レール摩耗量測定器２をレール１００に対して位置決めできる。詳しくは、基準部１０を底部上面１１３に当接させることで、レール摩耗量測定器２の縦方向の位置を位置決めできる。基準部１０を底部側面１１２に当接させることで、レール摩耗量測定器２の横方向の位置を位置決めできる。   The outer peripheral surface of the reference portion 10 of this embodiment is in contact with the bottom upper surface 113 and the bottom side surface 112 of the rail 100. Of the outer peripheral surface of the reference portion 10, a surface that contacts the bottom upper surface 113 is referred to as a first contact surface 11, and a surface that contacts the bottom side surface 112 is referred to as a third contact surface 13.

Next, a rail wear amount measuring device 3 according to a third embodiment of the present invention will be described.
As shown in FIG. 6, the rail wear amount measuring device 3 of the present embodiment is obtained by changing the shape of the reference portion 10 in the rail wear amount measuring device 1 of the first embodiment. Since the rest of the configuration is the same as that of the rail wear amount measuring instrument 1 of the first embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted.

本実施形態の基準部１０はその外周面がレール１００の底部上面１１３と腹部側面１２１と底部側面１１２とに当接する。基準部１０の外周面のうち底部上面１１３に当接する面を第１当接面１１、腹部側面１２１に当接する面を第２当接面１２、底部側面１１２に当接する面を第３当接面１３と称する。基準部１０を底部上面１１３と腹部側面１２１と底部側面１１２とに当接させることで、レール摩耗量測定器３をレール１００に対して位置決めできる。詳しくは、基準部１０を底部上面１１３に当接させることで、レール摩耗量測定器３の縦方向の位置を位置決めできる。基準部１０を腹部側面１２１および底部側面１１２に当接させることで、レール摩耗量測定器３の横方向の位置を位置決めできる。   The outer peripheral surface of the reference portion 10 of this embodiment is in contact with the bottom top surface 113, the abdomen side surface 121, and the bottom side surface 112 of the rail 100. Of the outer peripheral surface of the reference portion 10, the surface that contacts the bottom upper surface 113 is the first contact surface 11, the surface that contacts the abdomen side surface 121 is the second contact surface 12, and the surface that contacts the bottom side surface 112 is the third contact. This is referred to as surface 13. The rail wear amount measuring device 3 can be positioned with respect to the rail 100 by bringing the reference portion 10 into contact with the bottom top surface 113, the abdomen side surface 121, and the bottom side surface 112. Specifically, the vertical position of the rail wear amount measuring device 3 can be positioned by bringing the reference portion 10 into contact with the bottom upper surface 113. By bringing the reference portion 10 into contact with the abdomen side surface 121 and the bottom side surface 112, the position of the rail wear amount measuring device 3 in the lateral direction can be positioned.

摩耗が生じない底部上面１１３と腹部側面１２１と底部側面１１２とを基準とすることで、レール摩耗量測定器３を常に一定の位置に位置決めできる。そのため、摩耗量を正確に測定できる。   By using the bottom top surface 113, the abdomen side surface 121, and the bottom side surface 112 that do not wear as a reference, the rail wear amount measuring device 3 can always be positioned at a fixed position. Therefore, the wear amount can be accurately measured.
