Abstract
The utility model provides a measuring device for the shaft distance of the steering frame of a rail vehicle. A linear slide rail and a displacement sensor fixing scale are arranged on a base platform; the linear slide rail is connected with a mobile platform by a slide block on the linear slide rail; the mobile platform can move on the linear slide rail; the displacement sensor fixing scale is fixed with the mobile platform; a steering-frame locating wheel is arranged on the mobile platform; a mobile-platform locating mechanism is connected with the mobile platform, which can drive the mobile platform to move on the linear slide rail; a displacement-sensor position display and record device is connected with a displacement sensor moving scale and the displacement sensor fixing scale, so as to display and record the position of the displacement sensor moving scale in real time. The measuring device is arranged on the static-pressure test platform of the steering frame, which solves the measuring problem of the shaft distance of the steering frame under the action of non-load or any load.
Description
Technical field
The utility model discloses a kind of rail vehicle truck wheelbase measurement mechanism, belongs to vehicle testing device technique field.
Background technology
The actual value of the wheelbase of rail vehicle truck under zero load or full load condition is the key parameter that is related to the rail truck running status, usually the measuring method that adopts be before the bogie assembling to measuring with the relative dimensions of wheelbase associated components, extrapolate the actual value of wheelbase then.This is a kind of indirect measurement method, so poor accuracy.And be unloaded the measurement, can not measure the actual value of bogie wheelbase under full load condition.
Summary of the invention
The utility model proposes a kind of rail vehicle truck wheelbase measurement mechanism, this device is installed on the bogie static pressure test platform, solved under unloaded and any loading the problems of measurement of wheel-base bogie.
Technical solution of the present utility model: linear slide rail and displacement transducer scale are installed on the support platform, and linear slide rail links by oneself slide block and mobile platform on one's body, and mobile platform can move on linear slide rail.Moving chi of displacement transducer and mobile platform are fixed together, and are provided with the bogie locating wheel on moveable platform.Mobile platform detent mechanism and mobile platform link, can drive mobile platform moves on linear slide rail, displacement transducer position display and pen recorder move chi by signal cable and displacement transducer and scale links, and can show the also position of the moving chi of recorded bit displacement sensor in real time.
The utility model is when work, at first mobile platform and the moving chi of displacement transducer are driven into initial position by the mobile platform detent mechanism, then the mobile platform detent mechanism is adjusted to relaxed state, mobile platform can be moved freely, train wheel on the bogie drops on the locating wheel, driving moveable platform by locating wheel moves at linear slide rail, also driving simultaneously the moving chi of displacement transducer slides on the displacement transducer scale, the displacement of the moving chi of displacement transducer is sent on the numeric display unit by signal cable, detects the distance at two displacement platform centers.
Good effect of the present utility model is: be provided with the moving chi of displacement transducer on mobile platform, moving chi of displacement transducer and scale link by signal cable and displacement transducer position display and pen recorder, detect the distance at two displacement platform centers, the wheelbase of two axletrees of just same bogie.Solved under unloaded and any loading the problems of measurement of wheel-base bogie.
