(54) ПРИБОР ДЛЯ ЛИНЕЙНЫХ ИЗМЕРЕНИЙ(54) DEVICE FOR LINEAR MEASUREMENTS

Изобретение относитс к измерительной технике и предназначено дл измерени параметров шахтного рельсового и монорельсового пути.The invention relates to a measurement technique and is intended to measure the parameters of a mine rail and monorail track.

Известен путевой шаблон дл измерени параметров рельсового пути, содержащий корпус с размещенными в нем по оси подвижными ч неподвижными упорами, уровень и шкалы ширины 1.A track pattern is known for measuring the parameters of a track, comprising a housing with movable stops fixed in it along the axis, a level and scales of width 1.

Ввиду того что при измерении ширины железнодорожного рельсового пути рельсы уложены с большими радиусами закруглени , отпадает необходимость в строгой установке шаблона по нормали к кривой, на которой производитс измерение.Since, when measuring the width of a railroad track, the rails are laid with large rounding radii, there is no need to strictly set the template along the normal to the curve on which the measurement is made.

Даже при установке не по нормали к кривой ошибка при юмерении получаетс весьма малой.Even if the installation is not normal to the curve, the error in the measurement is quite small.

Однако при измерени х на закруглени х малого радиуса тер етс универсальность прибора.However, when measuring on roundings of small radius, the universality of the instrument is lost.

Известен также прибор дл линейных измерений , содержащий корпус, направл ющую со шкалой , расположенную на оси симметрии корпуса, два неподвижных упора, закрепленных на одной из сторон корпуса на одинаковом рассто нии от оси симметрии, подвижной наконечник, установле шый в направл ющей, один конец KOitipoго предназначен дл контакта с контролируемой поверхностью со стороны, противоположной неподвижным упорам, а другой конец кинематически св зан со шкалой на направл ющей (2).Also known is a device for linear measurements, comprising a housing, a guide with a scale, located on the symmetry axis of the housing, two fixed stops fixed on one side of the housing at the same distance from the axis of symmetry, a movable tip mounted in the guide, one end The KOitipo is designed to contact the controlled surface on the side opposite to the fixed stops, and the other end is kinematically connected with the scale on the guide (2).

Указанный прибор вл етс наиболее близким к изобретению по технической сущности и достигаемому результату.The specified device is closest to the invention in its technical essence and the achieved result.

Однако он не позвол ет измер ть радиус закруглени рельсового пути и, кроме того, при измерении ширины на малом радиусе закруглени погрешность измерени получаетс существенной .However, it does not allow to measure the radius of the track and, moreover, when measuring the width on a small radius of rounding, the measurement error is significant.

Целью изобретени вл етс расширение тех5 нологических возможностей прибора.The aim of the invention is to expand the technical capabilities of the device.

Указанна цель достигаетс тем, что прибор снабжен установленными на направл ющей дополнительными шкалами и подвижным наконечником , один конец которого преш)азначен This goal is achieved by the fact that the device is equipped with additional scales mounted on the guide and a movable tip, one end of which is

D for contact with the test surface from the fixed stops, and the other horse is kinematically associated with additional scales. The drawing shows the proposed device, opshchy view. The device for linear measurements contains a housing I, a guide 2 with a scale of 3 and additionally 1) 1 m of scales 4 and 5, giving fixed stops 6 and 7. movable tip 8 and additional folding tip 9, arrow 10 fixed on tip 8, the arrows 11 and 12, rigidly mounted on the tip 9. The scale 3 serves to measure the distance from the end of the movable tip 8 to the plane passing through the ends of the fixed stops 6 and 7. The scale 4 serves to introduce corrections to the scale readings 3. It is divided into two half the risk of 13, from which ITS countdown, in one half of the ideals of a plus sign (+), on the other - M1shus (-). The scale 5 serves to measure the radius of the track and is divided into two halves 14. The device operates as follows. The device is installed between the rails and on scales 3 and 4 read the width of the track, and pzhale 5 - the radius of rounding. If arrow 11 is on the plus floor of scale 4, then the reading of scale 3 must be added to the reading of scale 4, if arrow 11 is on the negative floor of 1, then from display of scale 3 it is necessary to subtract the reading of scale 4 rail track. If the arrow 12 is set at risk 14 on the scale 5, then this will correspond to the fact that the radius is equal to infinity, then the measurement is made on a straight path. If arrow 12 is set to any other indication, then it can be shown whether 4 is this curve concave or convex. The half-scale olla serves to measure the radius of curvature of the concave curve, and the other half of the scale convex. Thus, the device allows to measure the radius of curvature of the track and the swill to a minimum, the measurement error of the width of the track, the formula of the invention. from the sides of the body at the same distance from the axis of symmetry, a movable handpiece, mounted in a guide, one end of which is intended to contact the controlled surface on the side opposite to the stationary an end stop, and the other end is kinematically connected with a scale on a guide, characterized in that, in order to expand the technological capabilities of the device, it is equipped with additional scales mounted on the guide and a movable tip, one end of which is intended to contact the controlled surface from fixed stops, and the other end of K1 is schematically associated with additional scales.
