Abstract
The utility model discloses a measuring scale for measuring a reduction value of a railway switch. The measuring scale comprises a main board, wherein a window is arranged on one side of the main board; a slide slot which is through up and down is arranged in the main body and is corresponding to the window; a main scale which gets through the slide slot to extend along the slide slot is arranged in the slide slot; a vernier scale which is matched with the main scale is arranged on one side of the window; a spirit bubble is arranged on the top part of the main board; a magnet is arranged on the bottom part of the main board; a through hole is arranged on the middle part of the main board; and an adjusting bolt which gets through the bottom part of the main board is arranged in the through hole. The measuring scale has the following advantages: 1, the measuring precision is high, the precision of the spirit bubble does not exceed 4'/DIV(Division), the precision of the vernier scale is 0.05mm, and the composite error does not exceed 0.1mm; 2, the application range is broad, and the reduction value of a switch rail relative to a base rail can be measured, the reduction value of a centre rail relative to a wing rail can be measured; and after a timely roller and a point switch are installed, the measurement for the reduction value can be carried out; and 3, the size is small, the carrying is convenient, and the operation can be carried out by one person.
Description
Technical field
The utility model belongs to the track product, is 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),, do not have and impact or swag phenomenon so that operate steadily when making train cross trouble.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, detect the gap width L between tongue c top and the long leveling ruler a through Steel Ruler or clearance gauge;
(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, cause measuring basis (surface level at leveling ruler or suspension wire place) not overlap with design basis (the residing surface level of stock rail central point), deviation is arranged;
(2) reduction value is generally 0mm-5mm, and when using clearance gauge to measure, clearance gauge has error when piling up each other, 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 property 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.
The utility model content
The purpose of the utility model is the shortcoming that overcomes above measuring method, and a kind of dip stick that improves the measurement railway switch reduction value of accuracy is provided.
The utility model purpose is realized by following technical scheme:
The dip stick of measuring railway switch reduction value comprises a mainboard, is provided with a window in a side of mainboard, and it is corresponding with said window to be provided with the 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 said window is provided with the vernier scale that cooperates with main scale, and the top of said mainboard is provided with a spirit bubble, and the bottom of mainboard is provided with a magnetic patch; The middle part of said mainboard is provided with a through hole, in this through hole, be provided with one run through mainboard bottom set screw.
The bottom of said main scale is L shaped shape.
Be provided with sheet metal between said main scale and the mainboard sidewall, be provided with trip bolt at the sidewall of mainboard and said main scale located through sheet metal.
The utility model 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 mainboard is attached the benchmark curved surface that stays in stock rail; Can demonstrate the level on the plane of mainboard bottom through set screw and spirit bubble, unclamp trip bolt, main scale slided up and down along mainboard make the tested position at contact tongue top just, its bottom; Measured value-reduction value can be read through 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 through sheet metal easily.
The utility model is compared with existing measuring technique, has the following advantages:
(1) measuring accuracy is high, and 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.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
