しかしながら、従来技術は、本体フレーム３１０を水平に保たなければレール内側面と基準器との水平距離とレール頭面と基準器との高低差とを正確に測定できないという課題がある。したがって、経験の浅い作業者では正確に測定できないなどの人的な要因による測定誤差が生じてしまう。   However, the prior art has a problem that the horizontal distance between the rail inner surface and the reference device and the height difference between the rail head surface and the reference device cannot be accurately measured unless the main body frame 310 is kept horizontal. Therefore, a measurement error due to human factors occurs such that an inexperienced worker cannot accurately measure.

本考案は、このような課題に鑑みてなされたものであり、人的要因による測定誤差が生じにくい高低縦距測定器を提供することを目的とする。   The present invention has been made in view of such a problem, and an object of the present invention is to provide a high and low vertical distance measuring device in which measurement errors due to human factors are unlikely to occur.

本考案の高低縦距測定器は、基準器とレールとの位置関係を測定するための高低縦距測定器であって、距離と水平方向からの傾きを測定する測定部を備えることを前提としている。その上で、本考案の高低縦距測定器は、本体フレーム、ロック部、縦尺部、基準ピン固定爪、レール固定爪を備える。本体フレームは、外幹フレームと、一端が外幹フレーム内にかつ他端が外幹フレーム外に移動自在に配置された内幹フレームからなる。ロック部は、内幹フレームの他端に固定され、本体フレームの長手方向を水平に配置したときに鉛直方向となる向きに貫通孔を有する。縦尺部は、ロック部の貫通孔を貫通している。基準ピン固定爪は、縦尺部の一端に固定され、基準器に接触させる部分である基準ピン接触部を有する。レール固定爪は、基準ピン固定爪が下側になるように本体フレームの長手方向を水平に配置したときに、外幹フレームの下側に配置されるように外幹フレームに固定される。また、レール固定爪は、レール内側面と接触する平面である内側面接触部と、レール頭面に内側面接触部と平行な線で接触する曲面である凸部とを有する。縦尺部は、ロック部の貫通孔の内部に配置され得る範囲に複数の縦尺設定穴を有する。ロック部は、縦尺設定穴のいずれかに挿入することで縦尺部を固定するロックピンを有する。測定部は、内側面接触部と基準ピン接触部との本体フレームの長手方向に平行な方向の距離と、外幹フレームの水平方向からの傾きと、を測定できるように外幹フレームに取り付けられている。   The high / low vertical distance measuring device of the present invention is a high / low vertical distance measuring device for measuring the positional relationship between the reference device and the rail, on the premise that the measuring device measures the distance and the inclination from the horizontal direction. Yes. In addition, the height and distance measuring device of the present invention includes a main body frame, a lock part, a vertical part, a reference pin fixing claw, and a rail fixing claw. The main body frame includes an outer trunk frame and an inner trunk frame in which one end is disposed in the outer trunk frame and the other end is movably disposed outside the outer trunk frame. The lock portion is fixed to the other end of the inner trunk frame and has a through hole in a direction that becomes a vertical direction when the longitudinal direction of the main body frame is horizontally arranged. The longitudinal portion passes through the through hole of the lock portion. The reference pin fixing claw has a reference pin contact portion that is fixed to one end of the longitudinal portion and is a portion that comes into contact with the reference device. The rail fixing claw is fixed to the outer trunk frame so as to be arranged below the outer trunk frame when the longitudinal direction of the main body frame is horizontally arranged so that the reference pin fixing claw is on the lower side. The rail fixing claw includes an inner surface contact portion that is a flat surface that contacts the inner surface of the rail, and a convex portion that is a curved surface that contacts the rail head surface along a line parallel to the inner surface contact portion. The longitudinal portion has a plurality of longitudinal setting holes in a range that can be disposed inside the through hole of the lock portion. The lock portion has a lock pin that fixes the vertical portion by being inserted into any of the vertical setting holes. The measurement unit is attached to the outer trunk frame so that the distance between the inner surface contact part and the reference pin contact part in the direction parallel to the longitudinal direction of the main body frame and the inclination of the outer trunk frame from the horizontal direction can be measured. ing.

本考案の高低縦距測定器によれば、縦尺設定穴の位置でのみ縦尺部を固定できるので、レール固定爪の凸部と基準ピン接触部との本体フレームの長手方向と垂直な方向の距離は、どの縦尺設定穴にロックピンを挿入したかで決まる。そして、平面形状だった凸部を曲面にしたことで、本体フレームが傾いた際にレール頭面の接触点をレールの中心に位置しやすくし、高さ方向の誤差を少なくできる。   According to the high and low vertical distance measuring instrument of the present invention, since the vertical portion can be fixed only at the position of the vertical setting hole, the direction perpendicular to the longitudinal direction of the main body frame between the convex portion of the rail fixing claw and the reference pin contact portion The distance is determined by which longitudinal setting hole the lock pin is inserted into. And since the convex part which was planar shape was made into the curved surface, when the main body frame inclines, the contact point of the rail head surface can be easily located at the center of the rail, and the error in the height direction can be reduced.

本考案の高低縦距測定器であれば、その後、測定部で、内側面接触部と基準ピン接触部との本体フレームの長手方向に平行な方向の距離と、外幹フレームの水平方向からの傾きを測定すれば、本体フレームを水平に保ちながら測定する必要はない。   If it is the high and low vertical distance measuring instrument of the present invention, then, in the measuring unit, the distance between the inner surface contact part and the reference pin contact part in the direction parallel to the longitudinal direction of the main body frame and the horizontal direction of the outer trunk frame. If the inclination is measured, there is no need to measure while keeping the main body frame horizontal.

The present invention relates to the shape and structure of a high / low vertical distance measuring device including a measuring unit for measuring distance and inclination from the horizontal direction. The height / height distance measuring device 10 of the present invention includes a main body frame 110, a lock portion 170, a vertical portion 150, a reference pin fixing claw 160, and a rail fixing claw 140. The main body frame 110 includes an outer trunk frame 120 and an inner trunk frame 130 having one end placed in the outer trunk frame 120 and the other end movably disposed outside the outer trunk frame 120. The lock portion 170 is fixed to the other end of the inner trunk frame 130 and has a through hole in a direction that becomes a vertical direction when the longitudinal direction of the main body frame 110 is horizontally arranged. The longitudinal portion 150 passes through the through hole of the lock portion 170. The reference pin fixing claw 160 has a reference pin contact portion 161 that is fixed to one end of the longitudinal portion 150 and is in contact with the reference device 920. The rail fixing claws 140 are arranged on the outer trunk frame 120 so as to be arranged below the outer trunk frame 120 when the longitudinal direction of the main body frame 110 is horizontally arranged so that the reference pin fixing claws 160 are on the lower side. Fixed. The rail fixing claw 140 includes an inner surface contact portion 142 that is a flat surface that contacts the inner surface of the rail, a convex portion 141 that is a curved surface that contacts the rail head surface along a line parallel to the inner surface contact portion 142, and an outer trunk. A connection portion 143 connected to the frame 120 is included. The longitudinal portion 150 has a plurality of longitudinal setting holes 151 in a range that can be disposed inside the through hole of the lock portion 170. The lock unit 170 includes a lock pin 171 that fixes the vertical unit 150 by being inserted into any one of the vertical setting holes 151. A step number 152 may be further attached to the longitudinal portion 150. The stage number 152 is a mark indicating which longitudinal setting hole 151 the lock pin 171 is inserted into. The measurement unit 180 is configured to measure the distance between the inner surface contact portion 142 and the reference pin contact portion 161 in the direction parallel to the longitudinal direction of the main body frame 110 and the inclination of the outer trunk frame 120 from the horizontal direction. Attached to the trunk frame 120. Note that the measurement unit 180 also includes a display unit 181 and an operation unit 182.

高低縦距測定器１０の形状、構造の特徴について説明する。縦尺設定穴１５１の位置でのみ縦尺部１５０を固定できるので、レール固定爪１４０の凸部１４１と基準ピン接触部１６１との本体フレーム１１０の長手方向と垂直な方向の距離は、どの縦尺設定穴１５１にロックピン１７１を挿入したかで決まる。この距離が、図４のｈｎである。また、凸部１４１がレール頭面に内側面接触部１４２と平行な線で接触する曲面なので、容易に、本体フレーム１１０を傾けながら、内側面接触部１４２をレール内側面に接触させ、凸部１４１をレール頭面に接触させ、基準ピン接触部１６１を基準器９２０に接触させた状態にできる。そして、測定部１８０は、内側面接触部１４２と基準ピン接触部１６１との本体フレーム１１０の長手方向に平行な方向の距離（図４のＬ）と、外幹フレーム１２０の水平方向からの傾き（図４のθ）とを測定できる。つまり、図４のｈｎは作業者の経験にかかわらず容易に決まる。そして、本体フレーム１１０の水平に保つ必要がないので、経験の浅い作業者でも正確に図４のＬ，θを測定できる。なお、縦尺設定穴１５１同士の間隔は、体フレーム１１０を水平方向から傾けなければならない範囲（図４のθの範囲）をどの程度にするかから決めてもよい。 The features of the shape and structure of the high / low longitudinal distance measuring device 10 will be described. Since the vertical portion 150 can be fixed only at the position of the vertical setting hole 151, the distance between the convex portion 141 of the rail fixing claw 140 and the reference pin contact portion 161 in the direction perpendicular to the longitudinal direction of the main body frame 110 is determined in any vertical direction. It depends on whether or not the lock pin 171 is inserted into the scale setting hole 151. This distance is h n in FIG. Further, since the convex portion 141 is a curved surface that contacts the rail head surface with a line parallel to the inner surface contact portion 142, the inner surface contact portion 142 is easily brought into contact with the inner surface of the rail while the main body frame 110 is tilted. 141 can be brought into contact with the rail head surface, and the reference pin contact portion 161 can be brought into contact with the reference device 920. Then, the measuring unit 180 includes a distance (L in FIG. 4) in the direction parallel to the longitudinal direction of the main body frame 110 between the inner surface contact unit 142 and the reference pin contact unit 161 and the inclination of the outer trunk frame 120 from the horizontal direction. (Θ in FIG. 4) can be measured. That is, h n in FIG. 4 is easily determined regardless of the operator's experience. Further, since it is not necessary to keep the main body frame 110 horizontal, even an inexperienced operator can accurately measure L and θ in FIG. Note that the interval between the vertical scale setting holes 151 may be determined based on the extent to which the body frame 110 must be tilted from the horizontal direction (the range of θ in FIG. 4).

そして、レール内側面と基準器との水平距離（図４のＤ）とレール頭面と基準器との高低差（図４のＨ）は、次のように求めることができる。
Ｄ＝Ｌ×ｃｏｓθ−ｈｎ×ｓｉｎθ
Ｈ＝Ｌ×ｓｉｎθ＋ｈｎ×ｃｏｓθ The horizontal distance between the rail inner surface and the reference device (D in FIG. 4) and the height difference between the rail head surface and the reference device (H in FIG. 4) can be obtained as follows.
D = L × cos θ−h n × sin θ
H = L × sin θ + h n × cos θ

上述の説明では、測定部１８０はＬとθとを測定できることを説明した。測定部１８０が、さらに、操作部１８２からどの縦尺設定穴１５１にロックピン１７１を挿入したかを示す情報を受け取ることでｈｎの値を取得するようにし、上記の式でＤ，Ｈを計算し、表示すれば、レール内側面と基準器との水平距離（図４のＤ）とレール頭面と基準器との高低差（図４のＨ）を測定することも可能である。そして、本考案の高低縦距測定器１０の形状、構造であれば、作業者の経験などの人的な要因によらず正確に測定できる。 In the above description, it has been described that the measurement unit 180 can measure L and θ. The measurement unit 180 further obtains the value of h n by receiving information indicating which longitudinal setting hole 151 the lock pin 171 has been inserted from the operation unit 182, and sets D and H in the above formula. If calculated and displayed, the horizontal distance between the rail inner surface and the reference device (D in FIG. 4) and the height difference between the rail head surface and the reference device (H in FIG. 4) can be measured. And if it is the shape and structure of the high and low vertical distance measuring device 10 of this invention, it can measure correctly irrespective of human factors, such as an operator's experience.

また、図５のようにバラスト余盛９３１によって本体フレーム１１０を水平にすることが難しい場合（水平にするにはバラスト余盛を低くしなければならない場合）には、本体フレーム１１０を傾けた状態で測定すればよい。したがって、バラスト余盛９３１がある場合でも容易にレール内側面と基準器との水平距離とレール頭面と基準器との高低差を測定できる。   In addition, when it is difficult to level the main body frame 110 by the ballast extra 931 as shown in FIG. 5 (when the ballast extra scale must be lowered in order to be horizontal), the main body frame 110 is tilted. You can measure with. Therefore, even when the ballast extra 931 is present, the horizontal distance between the rail inner surface and the reference device and the height difference between the rail head surface and the reference device can be easily measured.
