Abstract
The invention discloses a measuring scale for measuring a lowering value of a railway turnout. The measuring scale comprises a main plate, one side of the main plate is provided with a window, and a longitudinally penetrated sliding groove corresponding to the window is arranged in the main plate; a main scale running through the sliding groove and sliding along the same is arranged in the sliding groove; one side of the window is provided with a vernier scale matched with the main scale; a spirit bubble is arranged at the top of the main plate, a magnetic block is arranged at the bottom of the main plate, and a through hole is arranged at the middle part of the main plate; and an adjusting screw penetrating through the bottom of the main plate is arranged in the through hole. The measuring scale has the following advantages that: 1, the measuring scale has high measurement accuracy, the accuracy of the spirit bubble is not more than 4'/DIV, the accuracy of the vernier scale is 0.05 mm and combined error is not more than 0.1 mm; 2, the measuring scale has a wide application range, can measure the lowering value of the a point rail relative to a stock rail, and also can measure the lowering value of a nose rail relative to a wing rail; even if a running roller and a point switch are mounted well, the measuring scale also can measure the lowering value; and 3, the measuring scale is small in volume, portable and convenient, and can be operated by only one person.
Description
Technical field
The invention belongs to the track product, be specifically related to a kind of dip stick of measuring railway switch reduction value.
Background technology
In the speed-raising railway switch, especially in the Line for Passenger Transportation track switch, (perhaps long heart rail is with respect to the reduction value of wing rail with respect to the reduction value of stock rail to tongue, abbreviate " reduction value " as) have strict requirement (permissible variation for ± 0.5mm), so that operate steadily when making train cross trouble, do not have and impact or swag phenomenon.The method of existing measurement track switch reduction value generally has two kinds:
(1) as shown in Figure 1, ride over long leveling ruler a on two stock rail b in the track switch outside, by the gap width L between Steel Ruler or clearance gauge detection tongue c top and the long leveling ruler a;
(2) adopt the string of a musical instrument to replace long leveling ruler, method is with (1);
More than the shortcoming of two kinds of methods have following some:
(1) because stock rail is an inclination 1:40 angle, causes measuring basis (surface level at leveling ruler or suspension wire place) not overlap, deviation is arranged with design basis (the residing surface level of stock rail central point);
(2) reduction value is generally 0mm-5mm, and when using clearance gauge to measure, clearance gauge has error when piling up mutually, can reach 0.3mm; When measuring, because the precision of Steel Ruler is 0.5mm, so there is bigger reading error with Steel Ruler; When using the string of a musical instrument to measure,, cause reliable measuring data not high because the characteristic (color and rigidity) of the string of a musical instrument itself is difficult for carrying out the judgement of gap and reading.
(3) on the line, on the mounting turnout after slide plate running roller and the goat, because a side tongue can be lifted by running roller, the big cross section place of tongue (the reduction value is less), the tongue height can surpass the stock rail height, more than two kinds of methods all no longer suitable.
(4) the measurement apparatus is many, carries inconvenience, generally wants two people's compounding practices.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above measuring method, a kind of dip stick that improves the measurement railway switch reduction value of accuracy is provided.
The object of the invention is realized by following technical scheme:
The dip stick of measuring railway switch reduction value comprises a mainboard, side at mainboard is provided with a window, it is corresponding with described window to be provided with a chute that runs through up and down in the mainboard, in chute, be provided with one and pass the main scale that chute slides along chute, one side of described window is provided with the vernier scale that cooperates with main scale, and the top of described mainboard is provided with a spirit bubble, and the bottom of mainboard is provided with a magnetic patch, the middle part of described mainboard is provided with a through hole, is provided with a set screw that runs through mainboard bottom in this through hole.
The bottom of described main scale is L shaped shape.
Be provided with sheet metal between described main scale and the mainboard sidewall, be provided with trip bolt at the sidewall of mainboard and described main scale located by sheet metal.
The present invention is owing to adopt said structure, wherein the plane of mainboard bottom is used to be placed on the curved surface of stock rail, the magnetic patch of mainboard bottom is used to inhale with the attached benchmark curved surface that stays in stock rail of mainboard, can demonstrate the level on the plane of mainboard bottom by set screw and spirit bubble, unclamp trip bolt, main scale is slided up and down along mainboard make the tested position at contact tongue top just, its bottom, measured value-reduction value can be read by vernier scale, the vertical range of measured workpiece can be accurately recorded with respect to stock rail curved surface point.The trip bolt that is located at the mainboard sidewall can be located main scale easily by sheet metal.
The present invention compares with existing measuring technique, has the following advantages:
(1) measuring accuracy height, the air level precision is no more than 4 '/DIV, and the vernier scale precision is 0.05mm, and composition error is no more than 0.1mm
(2) applied widely, can measure the reduction value of tongue with respect to stock rail, also can measure the reduction value of heart rail with respect to wing rail; In time running roller and goat install, and also can reduce the measurement of value;
(3) volume is little, and is easy to carry, and a people can operate.
The invention will be further described below in conjunction with drawings and Examples.
