Abstract
The utility model relates to a steel rail straightness measuring instrument which can measure the straightness state of the top and surface and the side surface of a steel rail. The utility model is an electromechanical integration device which integrates new techniques of computers, sensors, signal processing, precision mechanical machining, new materials, etc. into integration. The utility model is characterized in that a precise guide rail of which the effective length is 1 meter is used as a measuring base line, and the utility model can reflect true values and eliminates the defect of the measuring principle of a steel plate rule and feeler method. The utility model can realize the automatization and digitization of data acquisition and processing and can continuously measure the straightness data in two directions of the steel rail. The utility model has the advantages of compact structure, light weight, convenient carrying, convenient operation and high detecting efficiency.
Description
Technical field
The utility model be employ new technology (as: computer technology, sensor technology, signal processing technology, precise machine machining, new material technology etc.) in 1 meter long scope, measure the portable electromechanical integration equipment of railway track end face, side flatness data, its data acquisition, processing, Display Realization robotization, digitizing simultaneously.
Background technology
At present, the portable means of domestic measurement rail flatness are 1 meter long Steel Ruler and clearance gauge, its shortcoming is: can not reflect actual value most of the time, the measuring principle defectiveness: this mode belongs to discontinuous measurement, can only measure the data of several points: can not measure rail surface, side flatness data simultaneously; Owing to adopt manually-operated fully, detection efficiency is low.
The utility model content
Can not reflect actual value in order to solve existing measurement means, can not measure the data of rail both direction continuously simultaneously, adopt problem such as manually-operated fully, the utility model can be measured rail surface, side flatness data accurately, continuously, simultaneously, automatically by a kind of portable equipment.
The technical solution adopted in the utility model is: the rail flatness meassuring instrument mainly is made up of frame, portable computer two large divisions, and sensor, signal Processing interface board, power module etc. all are installed on the frame, connect by the cable that can plug joint between frame and the portable computer.During formal the detection, be to measure baseline, can reflect actual value, eliminated the measuring principle defective of existing measurement means with the precise guide rail.
Frame: length is about 1.2 meters, and claimed structure is firm, in light weight, waterproof is antirust, mainly adopts titanium alloy material.Mainly comprise: guide rail, slide head, electric interfaces box, support, accessory constituent.Guide rail is the agent structure of frame, adopts line slideway, is the mobile vehicle of slide head; Slide head is made up of slipper, sensor box body, moves on guide rail.3 sensors are installed in the slide head, wherein 2 is high accuracy displacement sensor, 1 vertical installation, and another level is installed, vertical with slideway, measure the data of rail surface, inboard working edge both direction, another sensor is a range sensor, for data acquisition provides sampling pulse, sampling interval is 1mm, in the long scope of 1 meter measurement base, can evenly gather 1000 data, can the continuous coverage rail surface, the flatness state of side; The electric interfaces box is fixed on a side of frame, for sensor provides power supply, and to sensor signal handle, digitizing conversion etc., the interface with computing machine also is provided; 2 supports are installed in the guide rail both sides, are the basis and the supports of whole frame; Accessory constituent comprises handle, locking switch, packing case etc.
Portable computer: digitized signal is handled, stored, show measurement data in real time, judging whether transfinites, and display waveform.
Characteristics of the present utility model are: adopt precise guide rail for measuring baseline, can reflect actual value, eliminated the measuring principle defective of existing method; Data acquisition, processing realize robotization, digitizing; The flatness data of energy continuous coverage rail surface, side; Measuring instrument compact conformation, weight is light, be easy to carry, easy and simple to handle, efficiency of measurement is high.
