The wheel diameter ruler of the utility model can replace the prior measuring instruments, and can satisfy requirements for modern railway construction.
Description
Technical field
The utility model belongs to detection range, relates to the diameter of railway wheel and the pick-up unit of diameter difference, especially a kind of railway wheel electron linkage digital display wheel footpath chi.
Background technology
Railway is the main artery of national economy, and its effect is very important.Along with the significantly raising of train running speed and the high-speed cruising of motor train unit train; To train main operation parts---the accuracy requirement of wheel further improves; Be related to stability and the security of train on heavy duty, the railway of running at high speed, and the impact capacity of anti-outside motive power.
At present, to the diameter of high speed wheel and the detection of diameter difference, adopt tradition " wheel footpath chi " usually.Wheel footpath chi is formed by working energetically the vernier scale that branch chi chi frame and both sides cross out, and the gauge head of measuring jaw and chi frame have a segment distance.Because the vehicle wheel footpath is bigger, causes chi frame span bigger, easy deformation and difficulty are controlled; In measuring process, the stressed a little distortion that can cause the chi frame of gauge head has had a strong impact on measuring accuracy simultaneously.
At present, though digital display wheel footpath chi is also arranged, employed liquid crystal indicator can only use more than temperature " 0 ℃ ", and the request for utilization temperature range of railway wheel footpath chi is at the environment of " ± 40 ℃ "; The micrometer device of railway wheel wheel footpath chi be score wheel footpath chi all adopt the milscale micrometer head with digital display wheel footpath chi, for screw thread moves, when measuring operation, need to move respectively reading chi frame and rotation differential head; Use inconvenient.
In sum, the accuracy detecting device of existing railway wheel is tradition comparatively, and measuring accuracy is not high, and efficiency of measurement is lower, can't satisfy the demand for development that current rail is built.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of railway wheel electron linkage digital display wheel footpath chi simple and convenient, that measuring accuracy is high, efficiency of measurement is high of measuring is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of railway wheel electron linkage digital display wheel footpath chi; Comprise chi frame, benchmark main scale, station meter frame, benchmark measuring jaw, reading main scale, reading chi frame, reading measuring jaw; The chi frame is domes; The difference level is installed coaxial benchmark main scale and reading main scale in the bottom, chi frame two ends of these domes, difference slide-and-guide reference for installation chi frame and reading chi frame on benchmark main scale and reading main scale, the horizontal reference for installation measuring jaw of station meter frame side; Reference for installation side head on this benchmark measuring jaw; Directly install the reading measuring jaw at reading chi frame side, it is characterized in that: the reading chi frame that the reading main scale is attend institute's activity-oriented installation is provided with capacitor grid transducer and digital display centimeter display and reading display, and an electronic digital centigrade indicator gauge head is installed on the reading measuring jaw.
And the running fix of said electronic digital centigrade indicator gauge head is employed in a micrometer adjusting screw of installing on the reading chi frame.
And said digital display centimeter display and reading display are LCD or transistor display.
The advantage and the good effect of the utility model are:
1, adopt the Electronic-digital Readout Measuring Tool of having popularized at present and having used in a large number between the reading main scale of epicycle footpath chi and the reading chi frame and the appearance grid sensing technology of using, measuring accuracy is high, accurately, fast.
2, the same application of electronic digital centigrade indicator gauge head of the micrometer device employing of epicycle footpath chi is to hold the grid sensing technologies; And form electron linkage with appearance grid sensing technology on the reading chi frame; Through the generated data (being the wheel physical size) that on reading chi frame, can directly demonstrate reading chi frame data and electronic digital centigrade indicator data after the electronics computing and electronic digital centigrade indicator data (for relative measurement time with), realized to wheel fast, accurately, DATA REASONING reliably.Measuring accuracy is high, speed is fast, and the soft elasticity gauge head of electronic digital centigrade indicator has well solved the problem that incidental chi frame is out of shape, rigidity is not enough of directly measuring of taking turns.
3, epicycle footpath chi adopts the mode of liquid crystal and two kinds of different demonstration measurement data of crystals pipe, and environment for use can reach ± and 40 ℃, to satisfy the weather measurement requirement of different regions.
4, the utility model one-piece construction is simple; Design science is reasonable, and is easy to use, and wheel footpath measuring accuracy Gao Bingke carries out multinomial measurement function as presetting several settings, relative measurement, maximum measurement etc.; Accuracy rate is high; Measure rapidly, complete alternative existing survey instrument, the needs that modern railways is built are satisfied in perfection.
