Axial pin screw fixes the other end for the measurement sensor being connect with connecting rod pivot angle indicating arm, connects in the left side contacted with third rail
Bar one end band is there are two measurement wheel and is equipped with tensioning spring, mechanical arm can be made to be close to third rail by spring and measurement wheel
It is moved to the effect continuously measured.
A kind of subway third rail measurement mechanical arm, it is characterised in that：Vertical survey is installed in the bottom surface contacted with third rail
Amount wheel, lateral displacement sensor is installed on cross measure wheel contact with third trackside face, using one by vertical measurement wheel with
Third rail that one cross measure wheel collectively forms measures wheeled measuring claw, realization and third rail medial surface and bottom surface it is close
Patch, lateral displacement sensor detect that cross measure wheel and third rail medial surface be closely connected in real time and the cross measure wheel that occurs relative to
The displacement of wheeled measuring claw matrix, the measurement sensor being connect with connecting rod pivot angle indicating arm are detected as remaining vertical in real time
The angular displacement for the four-bar linkage structure connecting rod pivot angle that measurement wheel is closely connected with third flange of rail face and occurs, even if in continuous moving
Data can be monitored and obtained in real time, and the data obtained by above structure are accurate and are not easy because operational issue obtains mistake
Data.
It is an advantage of the invention that：The present invention is installed on rail checking instrument, by rail checking instrument keep its relative to
The relative position of two strands of rail surfaces of track or so and track centre；During the continuous implementation of rail checking instrument, use
Four-bar linkage structure all installs displacement sensor at the both ends end to end of connecting rod, can be close to subway by spring and measurement wheel apparatus
Third rail medial surface and bottom surface are in rolling contact, and the transverse direction of continuous subway third rail and vertical letter can be obtained by sensor
Breath.Can it is simple, efficiently, it is accurate, continuously measure the stagger of third rail and lead height, without manually in continuous measurement process
Intervene, easy to operate, Measurement results are expressed with digital information, are remarkably improved working efficiency, are reduced labor intensity, improve ground
The level of informatization of iron third rail detection.

Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and specific embodiments：
A kind of subway third rail measurement mechanical arm, it is characterised in that：Using one by the double leval jib knot with connecting rod pivot angle indicating arm
15 parallel motion measuring arm of structure, four connecting rods are linked in sequence, and allow its activity, left side connecting rod by bearing connection between connecting rod
It is connect by first bearing 3 with the horizontal survey arm upper connecting rod 4 with pivot angle indicating arm, on the horizontal survey arm with pivot angle indicating arm
Connecting rod 4 is connect with right side connecting rod by second bearing 6, and right side connecting rod is connected with horizontal survey arm lower link 10 by 3rd bearing 9
It connects, left side connecting rod is connect with horizontal survey arm lower link 10 by fourth bearing 11, and the left side connecting rod and subway of measurement wheel are carried
Third rail 14 contacts, and right side connecting rod is connected with rail checking instrument 16, in the horizontal survey arm upper connecting rod 4 with pivot angle indicating arm
Between position fill tensioning tension spring connection left side connecting rod, pass through on 4 top of horizontal survey arm upper connecting rod with pivot angle indicating arm upper
