Description
Technical field
The invention belongs to gauge field of measuring technique, are related to a kind of adaptive mechanism for gauge measurement.
Background technique
In railway technology development, the measurement of contact gauge has many advantages, such as that the accurate height of measurement, accuracy is good, real-time is good,
But contact gauge measurement needs to meet gauge in the variation of 1410mm to 1470mm, and need can at minimum gauge
Be easy by contact type measurement equipment folder among two tracks, to measure the gauge of track medial surface.
Summary of the invention
The purpose of the present invention is: in view of the deficiencies of the prior art, a kind of adaptive mechanism for gauge measurement is proposed,
So that the mechanism can satisfy contact gauge measurement request.
The technical scheme is that
Travelling wheel and mobile erecting bed 1 are connected.
Mobile erecting bed 1 is fixedly connected by screw with two guide shafts 2, and each guide shaft 2 passes through two linear bearings and base
Seat 9 connects, and guide shaft 2 can slide axially in linear bearing.In one end of guide shaft 2, two guide shafts are connected using connecting plate 3
2, on two guide shafts 2, pedestal 4 after being connected by linear bearing passes through two connecting rods 5 and two rocker arms 6 on rear pedestal 4
It is connected, rotation axis 7 is fixedly connected with swing handle 8.
Measuring basis platform 11 is connect by two linear bearings with two small guide shaft 13, and small guide shaft 13 is by screw and moves
Dynamic erecting bed 1 is fixedly connected.Small preloading spring is co-axially mounted with small guide shaft 13, and between measuring basis platform 11 and mobile erecting bed
Between 1.
Track gauge sensor is installed on datum plate 10, and datum plate 10 is fixed on pedestal 9.
Track gauge sensor is contacted by the pretightning force of sensor itself with measuring basis platform 11.
The swing handle 8 can be rotated with 180 °.It is rotated by swing handle 8, rotation axis 7 connected to it, rocker arm
6, connecting rod 5 generates displacement, axial movement of the pedestal 4 along guide shaft 2 after drive.And then mobile installation is pushed by big preloading spring
Platform 1, guide shaft 2 along linear bearing axial movement.In orbit, by the pretightning force of big pre- spring, guarantee on mobile erecting bed 1
Anticollision wheel can always with track on the inside of face contact.The preload by small preloading spring is taken turns in measurement on measuring basis platform 11,
It is adjusted in a small range, and guarantees that measurement wheel also being capable of real-time contact track medial surface.Also, measurement wheel is not subject to pre-tighten bullet greatly
The pretightning force of spring is solely subjected to the pretightning force of small preloading spring.Measurement is taken turns with measuring basis platform 11 in measurement direction relative stiffness, therefore
The track gauge sensor that the track medial surface variation that measurement wheel captures can be contacted with measuring basis platform 11 obtains.
The invention has the advantages that
By swing handle, gauge institutional adjustment range can be made to be adjusted to the state smaller than 1410mm, be easy rail
Away from measuring device folder and two tracks；Gauge mechanism can be adjusted to the state bigger than 1470mm, in the feelings of maximum gauge
Under condition, gauge mechanism can also guarantee to guarantee between track with the presence of certain pretightning force pre- required for contact type measurement
Clamp force exists in real time, measures true gauge data in real time.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is side view of the present invention.
Specific embodiment
As depicted in figs. 1 and 2, group of the invention becomes travelling wheel and mobile erecting bed 1 is connected.Mobile erecting bed 1 passes through
