Description
Technical field：
The present invention relates to track traffic rail maintenance equipment technical field, is a kind of portable rail tunneling boring profile geometry
Parameter detecting instrument.
Background technology：
The detection of rail tunneling boring profile geometric parameter, is still model detection (ginseng as defined in Chinese Railway standard at present
Yue Yuan Ministry of Railways TB/T 3276-2011 " rail for high-speed railway " and TB/T 2344-2012 " 43kg/m~75kg/m hot-rolled steels
Rail order technical conditions "), it is external in recent years and domestic also have the portable instrument of developing laser means measurement and mechanical
Rail head of rail measuring instrument, but all it is only limitted to rail head position measurement (being mainly used for measuring rail head abrasion and profile reparation), it is impossible to
The technology geometric parameter state of the whole rail of track.Model detection then not only easily is influenced to survey by factors such as manual operation, model abrasions
Amount as a result, and its measurement result be also only limitted to qualitative acceptance or rejection, data volume is less.Laser means measure also easy light
The restriction of system, as portable dam, its measurement accuracy and price factor, fail to obtain formal use.
The content of the invention：
The purpose of the present invention is to solve the inspection as rail tunneling boring profile geometric parameter basic in track traffic
Survey problem.Realize rail tunneling boring profile physical dimension and quantify detection.To improve and ensureing rail quality, train operation is safeguarded
Safety provides foundation.
Because railway technology, the particularly raising of train operational safety and speed is (complete with profile of steel rail physical dimension
Section contour curve data) it is related, therefore accurate grasp rail physical dimension, for Rail Production unit, quality inspection department
And the unit such as construction and maintenance is all significant.
To reach above-mentioned purpose, solution of the invention is：
A kind of portable rail tunneling boring profile geometric parameter detector for being suitable for using in track traffic.The detector by
Instrument stand, clamping device, determine the compositions such as encoder, master connecting-rod, dynamic encoder, swing arm, measurement bow-shaped arm, roller.Swing arm and survey
Measure bow-shaped arm to be connected by rotatable joint, so as to ensure that 180 ° of revolutions can be done and keep relatively solid by measuring bow-shaped arm and swing arm
It is fixed, the roller of measurement bow-shaped arm end is made 360 ° of slips close to rail profile.
During work, instrument stand is placed at the top of rail and is inhaled by clamping device (switchable magnetic substance or mechanical clamp arm)
It is attached or be fixedly clamped, determine encoder and be installed in instrument stand, its main shaft is connected with master connecting-rod one end, and dynamic encoder is installed on main company
The other end of bar, can rotate with master connecting-rod around encoder is determined.Swing arm one end is connected with dynamic encoder main shaft, and the other end is by returning
Turn joint to be connected with measurement bow-shaped arm, the string of a musical instrument of measurement bow-shaped arm and the center line of swing arm is in a straight line, Er Qieke
With accurate and easily carry out positive and negative each 180 ° of revolution.
Feature of the present invention is to enable 360 ° of the roller of its termination complete by a precisely designed measurement bow-shaped arm
Keep to orientation contacting with rail profile, then compiled two by control device (including control board and software systems)
Code device gathers the data to be formed and uploads to host computer by the pretreatment of program curing, is shown in management platform.This method behaviour
Make simple, high certainty of measurement, suitable for currently establishing the technical characterstic of big data management platform.

Embodiment：
The further description of embodiment is carried out to the present invention below in conjunction with the accompanying drawings.
A kind of as shown in Figure 1, portable rail tunneling boring profile geometric parameter detector for being suitable for using in track traffic.
The detector by instrument stand 1, clamping device 2 and 3, determine encoder 4, master connecting-rod 6, dynamic encoder 5, swing arm 7, measurement bow-shaped arm 9,
The grade of roller 10 forms.Swing arm 7 and measurement bow-shaped arm 9 are connected by rotatable joint 8, so as to ensure to measure bow-shaped arm 9 and swing arm 7
180 ° can be done to turn round and keep being relatively fixed, the roller of 9 end of measurement bow-shaped arm is made 360 ° of slips close to rail profile.
During work, instrument stand is placed at the top of rail and is fixedly clamped by the absorption of clamping device 2 and 3, determines encoder 4 and installs
