Description
Technical field
The utility model relates to railway equipment field, specifically, relates to a kind of rail measuring instrument.
Background technology
The height to rail, rail head width, web of the rail thickness, flange of rail width, flange of rail edge thickness, end face gradient and end face degree of asymmetry is needed to measure before rail welding.Current in measuring process, above-mentioned test item is manual measurement, and precision is very low, and because needing the project of detection too much, causes staff to work burden comparatively greatly, and overall measurement efficiency is comparatively low.
Therefore, be necessary to develop a kind of device, realize the accurately efficient of the height of rail, rail head width, web of the rail thickness, flange of rail width, flange of rail edge thickness, end face gradient and end face degree of asymmetry and measure.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of rail measuring instrument.Rail measuring instrument provided by the utility model, can fix on rail, carries out high-acruracy survey by laser sensor.
In order to reach above-mentioned purpose, the utility model adopts following technical scheme:
A kind of rail measuring instrument, comprising:
Base, the left end of this base is fixedly connected with grip block, forms the draw-in groove for fixing rail between grip block and base;
The right-hand member of described base is fixedly connected with riser, and the both sides of riser are provided with slide rail, and the top of riser is provided with motor, and the force-output shaft of motor is connected with leading screw, and with nut on leading screw, described nut is fixedly connected with laser sensor;
Described laser sensor is also fixedly connected with slide plate, and the two ends of slide plate are provided with the slide block suitable with described slide rail;
Wherein, described laser sensor completes the measurement to rail by to-and-fro movement under the drive of motor.
Preferably, the left end front of described base is fixedly connected with location-plate.
Preferably, the left end reverse side of described base and closing handle are threaded connection.
The beneficial effects of the utility model are:
(1) realize the accurate location of this device on rail by grip block and fixing handwheel, avoid, in measurement process, large-amplitude sloshing occurs thus reduce measuring accuracy;
(2) motor drives laser sensor to-and-fro movement by leading screw and nut, laser sensor utilizing emitted light curtain in motion process completes the high-acruracy survey of height, rail head width, web of the rail thickness, flange of rail width, flange of rail edge thickness, end face gradient and end face degree of asymmetry to rail, and measurement result and efficiency are all better than manually.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front elevation of Fig. 1;
Fig. 3 is the partial enlarged drawing at A place in Fig. 1;
In figure: 1, base, 2, grip block, 3, draw-in groove, 4, riser, 5, slide rail, 6, motor, 7, leading screw, 8, nut, 9, laser sensor, 10, slide plate, 11, slide block, 12, location-plate, 13, closing handle, 14, light curtain.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment 1: a kind of rail measuring instrument, its structure as Figure 1-3, comprising:
Base 1, one end of this base 1 is fixedly connected with two grip blocks 2, forms the draw-in groove 3 for fixing rail between two grip blocks 2 and base 1;
The other end of described base 1 is fixedly connected with riser 4, and the both sides of riser 4 are provided with slide rail 5, and the top of riser 4 is provided with motor 6, and the force-output shaft of motor 6 is connected with leading screw 7, and with nut 8 on leading screw 7, described nut 8 is fixedly connected with laser sensor 9; Laser sensor 9 can select measurement range at the linear transducer of more than 150mm.
Described laser sensor 9 is also fixedly connected with slide plate 10, and the two ends of slide plate 10 are provided with the slide block 11 suitable with described slide rail 5;
Wherein, described laser sensor 9 completes the measurement to rail by to-and-fro movement under the drive of motor 6.
The left end front of described base 1 is fixedly connected with location-plate 12.
Left end reverse side and the closing handle 13 of described base 1 are threaded connection.
As better selection, motor 6 can select servomotor or stepper motor.
During use, snapped in by rail in draw-in groove 3, rail-end withstands on location-plate 12, then screws closing handle 13, completes location.Again laser sensor is connected with measuring system (as PC).Motor 6 rotating, then leading screw 7 also can rotating, and accordingly, nut 8 just drives laser sensor 9 to move up and down.The light curtain 14 that laser sensor 9 sends constantly changes in moving process, then the feedback signal that receives of laser sensor is also in continuous change, after the measured system process of feedback signal, can demonstrate the several data of measured rail.
After have employed said structure, this device achieves the high-precision rapid survey of rail height, rail head width, web of the rail thickness, flange of rail width, flange of rail edge thickness, end face gradient and end face degree of asymmetry, and significantly reduces the labour intensity of staff.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
