Abstract
The utility model discloses a single support rail stand detector for assisted detection of rail slab grinding size. One end of a spacing connecting rod is connected to a left measuring block via a left lock nut, the other end of the spacing connecting rod is connected with a right measuring block via a right lock nut, and the two ends of the spacing connecting rod are both provided with outer threads; inner cavities of one end of the left measuring block and one end of the right measuring block are provided with inner threads, and gradient of the end face of the other end of the left measuring and gradient of the end face of the other end of the right measuring block are the same with that of a designed rail cant; and the left lock nut and the right lock nut are screwed onto the spacing connecting rod and tightly lock the same. The detector is capable of detecting small jaw distance of a single support rail stand with measurement accuracy reaching 0.05mm. The detector has the advantages of meeting accuracy requirement of 375.6+-0.5mm of the small jaw distance, having the spacing rod to adjust measured values left to right, simple structure, light weight, low cost, easy splicing, convenient and speedy utilization, and saving nine to ten minutes per slab, thereby increasing grinding speed and being widely applied to railway single support rail stands.
Description
Technical field
This practicality relates to track plate auxiliary detection device, is specifically related to a kind of single support rail platform checkout gear of track slab polishing auxiliary detection size.
Background technology
In CRTS II track slab construction process, owing to influenced by the dynamic balancing of machine tool track structure, emery wheel, the pollution level of track plate, the water droplet of polishing pedestal, the pollution of laser instrument etc., track plate physical dimension after the polishing may lattice point (red sector) can occur not conforming to when carrying out laser scanning measurement.Measuring system with grinding machine detects, and is that 20 support rail platforms of whole plate are carried out, can not be at some or several support rail platforms.Moreover, go to detect the oversize defective of time that has cost with the measuring system of grinding machine.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is in light weight, and cost is low, single support rail platform checkout gear of a kind of accurately track slab polishing auxiliary detection size easy to use.
In order to overcome the deficiencies in the prior art, the technical solution of the utility model is to solve like this: a kind of single support rail platform checkout gear of track slab polishing auxiliary detection size, special character of the present utility model is that an end of spacing connecting rod is connected by left locking nut and left side measurement piece, the other end of spacing connecting rod is connected with the right piece of measuring by right locking nut, the equal car in the two ends of described spacing connecting rod has external screw thread, piece is measured on a described left side, a right end inner chamber car of measuring piece has internal thread, piece is measured on a left side, the end face gradient of the other end of right measurement piece is identical with the rail cant of design, left side locking nut, right locking nut screws on the spacing connecting rod, and locking spacing connecting rod.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the spacing bar structural representation of Fig. 1;
Fig. 3 is the measurement piece broken section structural representation of Fig. 1;
Fig. 4 looks perspective view for the measurement piece left side of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing summary of the invention is described further:
With reference to Fig. 1～shown in Figure 4, a kind of single support rail platform checkout gear of track slab polishing auxiliary detection size, one end of spacing connecting rod 3 is measured piece 1 by a left locking nut 2 and a left side and is connected, the other end of spacing connecting rod 3 is connected with the right piece 5 of measuring by right locking nut 4, the equal car in the two ends of described spacing connecting rod 3 has external screw thread, piece 1 is measured on a described left side, a right end inner chamber car of measuring piece 5 has internal thread, piece 1 is measured on a left side, the end face gradient of the other end of right measurement piece 5 is identical with the rail cant of design, left side locking nut 2, right locking nut 4 screws on the spacing connecting rod 3, and locking spacing connecting rod 3.
In sum, using method of the present utility model is explained as follows:
1, be connected with each other each parts as a whole according to assembly structure schematic diagram shown in Figure 1;
2, after lattice point (red sector) appears not conforming in track slab polishing, adjust left locking nut 2, right locking nut 4 with slide measure, and its plant bulk adjustment is reached standard value, lock respectively with locking nut, and then review with slide measure;
3, auxiliary detection device is placed on the support rail platform to be checked and detects.
If support rail platform small forceps is made a slip of the tongue greatly, then measure its gap with clearance gauge along Y direction, can obtain its reading, to readjust cutter then and mend, described cutter is mended and is meant emery wheel in the YOZ plan-position, determines the polishing amount by Y-axis coordinate, Z axial coordinate;
If it is little that support rail platform small forceps is made a slip of the tongue, auxiliary detection device just is difficult to put into, even put in, the inclination angle of its rail cant and both sides all exceeds standard, and needs polishing again.
Ordinary circumstance is, auxiliary detection device is placed on the little jaw, and the inclination angle of rail cant and both sides is very identical, can easily slide along X-direction, does not rock, and left and right sides clearance gauge plug is not entered.
When polishing good track plate when accurately measuring existing nonconformance, two kinds of possibilities are arranged, first kind, the plate after the polishing is qualified, because laser instrument is contaminated or measurement point has water, deviation appears in the laser beam reflection in the measurement, causes measuring inaccurate.Second kind, because there are accidentalia in grinding machine, emery wheel and dynamically balanced adjustment thereof, cause the polishing of support rail platform to exceed standard, laser detection is defective.
To first kind of situation, detect with servicing unit, measure and qualifiedly just can let pass.To second kind of situation, measurement finishes, and detects still defectively, find out its reason, again polishing.
In actual bruting process, first kind of situation defective (red sector) accounts for 98% of total amount, therefore, detects track plate (red sector) with aided measurement device, and be very necessary.
To measure piece during use earlier and be connected, adjust to suitable length then with the spacing bar.Frock is placed on the support rail platform that finishes of polishing, and slides along the rail support groove direction.Excesssive gap, can add clearance gauge and measure.Detection finishes, be with its servicing unit scrub, and oiling is antirust.
The utility model compared with prior art can detect the small forceps mouth distance of single track, and its certainty of measurement can reach 0.05 millimeter. Satisfy the small forceps mouth apart from the required precision that is 375.6 ± 0.5 millimeters, the spacing bar can about adjust measured value, structure tube list, in light weight, cost is low, easily assembly unit, convenient to use, this checkout gear is used than not adopting this auxiliary detection device in the plate field of certain special line for passenger trains for example, every block of plate was saved 9-10 minute, thereby had accelerated polishing speed. The utility model auxiliary detection device also is applicable to the auxiliary detection of no slag track I template small forceps distance except above-mentioned advantage. Be widely used in railway list track and detect use.
