Abstract
The utility model relate to a flatness measuring instrument, in particular to a measuring instrument for measuring the flatness of railway steel rails. The flatness measuring instrument comprises a stand, wherein the stand comprises a guide rail which is provided with a traveling mechanism capable of moving along the guide rail back and forth; and an electromagnetic induction probe is mounted on the traveling mechanism. A motor is further mounted at one end of the guide rail; an encoder is mounted at the other end of the guide rail; and the motor, the electromagnetic induction probe and the encoder are connected through a driving steel wire rope. The flatness measuring instrument can continuously measure the distance change from the surface of the steel rail to the probe according to the movement of the electromagnetic induction probe along a high-precision linear guide rail, thereby calculating the flatness of the surface of the steel rail. The data communication can be carried out between a signal processing board and a palm computer through a bluetooth model; and the programmed data processing software can be used for displaying an oscillogram on the detection surface, linearly fitting the measuring data and calculating the maximum value and the minimum value. The flatness measuring instrument has lightweight structure and high detection speed, and is convenient for carrying and convenient and quick for operation.
Description
Affiliated technical field
The utility model relates to a kind of flatness meassuring instrument, relates in particular to a kind of measuring instrument that is used to measure the railway track flatness.
Background technology
Raising along with train speed, the wheel that the uneven compliance of rail vertical section (comprising rail surface, workplace) causes sharply increases the impact load of rail, may cause that not only rail fracture, track component lost efficacy, and easily cause rolling stock parts hurt.Also there is the more serious problem that transfinites in the steel rail weld joint irregularity amplitude of the quasi high-speed circuit of China, high-speed railway test section.The reason that causes this phenomenon is except the welding technology horizontal factor, the another one key factor lacks the high-precision test means exactly and instructs welding, repairs, relied on the detection method of artificial clearance gauge obviously can not satisfy accuracy requirement in the past, and checking efficiency is low.Therefore, light, the high-precision rail level shortwave irregularity measurement mechanism one steel rail weld joint flatness meassuring instrument of exploitation is just necessary.
Summary of the invention
For the defective that the efficient that overcomes prior art is hanged down low precision, the utility model provides a kind of high-precision flatness meassuring instrument of robotization.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of flatness meassuring instrument, it is characterized in that comprising a frame, described frame comprises a guide rail, have a running mechanism that can move around along guide rail on the described guide rail, on the described running mechanism electromagnetic inductive probe is installed.
Described guide rail one end also is equipped with a motor, and the other end is equipped with a scrambler, and a shackle line couples together described motor, electromagnetic inductive probe and scrambler.
The utility model can move the variable in distance of continuous coverage rail surface to probe along the high precision linear guides according to electromagnetic inductive probe, thereby calculates the flatness on rail surface.Carry out data communication by bluetooth module between signal-processing board and the palm PC, and the data processing software by working out, can show the oscillogram that detects the surface, and can carry out calculating minimum and maximum value behind the linear fit measurement data.The utility model structure is light, be easy to carry, simple operation, detection speed are fast.
Below in conjunction with accompanying drawing the utility model is described further:
Description of drawings
Fig. 1 is a rack construction synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises a frame, and described frame comprises a guide rail 5, has a running mechanism 3 that can move around along guide rail 5 on the described guide rail 5, and electromagnetic inductive probe 2 (current vortex sensor) is installed on the described running mechanism 3.Described guide rail 5 one ends also are equipped with a motor 1, and the other end is equipped with a scrambler 6, one shackle lines 4 described motor 1, electromagnetic inductive probe 2 and scrambler 6 are coupled together.
After palm PC sends the measurement instruction, motor 1 drives wire rope 4 and moves, thereby realize running mechanism 3 moving along guide rail 5, electromagnetic inductive probe 2 can continuous detecting its distance to rail surface 7, scrambler 6 is write down the displacement that relatively moves simultaneously, detects the logical bluetooth module of saying of data and sends to palm PC and preservation.
After measuring end, the special software of working out on the palm PC is handled measurement data automatically, the oscillogram that can show measurement data, and automatically data are carried out the measuring error that linear fit causes with the position defective that overcomes measurement starting point and terminal point, and according to data computation car maximal value and minimum value after the match, thereby calculate the flatness of measurement.
