Abstract
The invention discloses a detection scale of relative height difference of an upper slope of a railway turnout base plate and an upper surface of a bedplate, which is composed of a base, a main scale, a vernier frame, a cross rod and a scale base, wherein the bottom surface of the base is a slope of which the gradient and the slant are coincident with the gradient and the slant of the base plate; the main scale is vertically fixed on the upper end surface of the base; the vernier frame is sheathed on the main scale to slide up and down along the main scale; the upper part of the vernier frame is a vernier, and the lower part is provided with a horizontal through hole; the cross rod is horizontally inserted in the horizontal through hole to slide left and right; and the scale base is fixed on the right end of the cross rod, and the front end surface of the scale base is provided with a measure meter holder. The detection scale of the invention has simple structure, flexible operation, accurate measurement and favorable adaptability, and can detect the relative height difference of all railway turnout base plates with the slopes and the bedplate as well as detect the slope manufacturing error situation.
Description
Technical field
The present invention relates to a kind of railway turnout base plate ramp and platen upper surface relative relief detection ruler.
Background technology
In the special turnout switch part of high speed visitor, since stock rail and tongue scold from closely connected needs, all adopt the backing plate have sliding bed platen under the rail, the needs when can 1: 40 inclined-plane of backing plate and platen upper surface relative relief satisfy the short transverse relative position of direct relation stock rail and tongue and railway laying in circuit and run.At present, detection for 1: 40 inclined-plane of backing plate and platen upper surface relative relief, adopt common pit gauge to measure, because plane on common pit gauge and the backing plate, platen upper surface surface of contact is less and contact area is limited and measured zone backing plate plane mismachining tolerance, the numerical value that causes measuring with the method can not fully, accurately reflect the actual conditions of 1: 40 inclined-plane and platen upper surface relative relief.
Summary of the invention
The technical matters that the present invention solves: design a kind of railway turnout base plate ramp and platen upper surface relative relief detection ruler; improve the accuracy that backing plate ramp and platen upper surface relative relief detect; the short transverse relative position of guaranteeing stock rail and tongue meets request for utilization, effectively avoids the generation of " empty boatswain chair " phenomenon in the installation process.
The technical solution used in the present invention: a kind of railway turnout base plate ramp and platen upper surface relative relief detection ruler, constitute by base, main scale, cursor frame, cross bar and gauge stand, the bottom surface of base is and backing plate ramp gradient, oblique consistent inclined-plane, main scale is vertically fixed on the upper surface of base, cursor frame is sleeved on the main scale and can slides up and down along main scale, the top of cursor frame is vernier scale, and the bottom is shaped on horizontal through hole, and the cross bar level is inserted in the horizontal through hole and can horizontally slips; Gauge stand is fixed on the right-hand member of cross bar, and the front end face of gauge stand is equipped with the meter clamper.
The bottom surface of described base is and backing plate ramp gradient, oblique 1: 40 consistent inclined-plane.
The bottom surface of described base is shaped on groove.
Horizontal through hole on the described cursor frame is a square hole, and the cross section of cross bar is square, and cross bar and horizontal through hole are clearance fit.
Advantage that the present invention compared with prior art has and effect:
1, simple in structure, easy to operate, measure accurately, guarantee that the short transverse relative position of stock rail and tongue meets request for utilization, effectively avoid the generation of " empty boatswain chair " phenomenon in the installation process.
2, adaptability is good, can carry out relative relief detection and the detection of inclined-plane foozle situation to all canted tie plates of railway switch and platen.

Fig. 2 is the left view of Fig. 1;
Fig. 3 is user mode figure of the present invention.
Embodiment
Below in conjunction with accompanying drawing 1,2,3 a kind of embodiment of the present invention is described.
A kind of railway turnout base plate ramp and platen upper surface relative relief detection ruler are made of base 1, main scale 2, cursor frame 3, cross bar 4 and gauge stand 5.The bottom surface of base 1 is and backing plate ramp gradient, oblique 1: 40 consistent inclined-plane, main scale 2 is a ruler, is vertically fixed on the upper surface of base 1, and cursor frame 3 is sleeved on the main scale 2 and can slides up and down along main scale, the top of cursor frame 3 is vernier scale 6, and the bottom is shaped on horizontal square hole 7.Vernier scale 6 is identical with the cooperation and the vernier caliper of main scale 2 scales, and effective accuracy can be accurate to 0.02mm.The cross section of cross bar 4 is square, and cross bar 4 is a clearance fit with horizontal square hole 7.Cross bar 4 levels are inserted in the horizontal square hole 7 and can horizontally slip; Cross bar 4 length are generally 190mm, and in proof strength, it is enough big to take into account measured zone.Gauge stand 5 is fixed on the right-hand member of cross bar 4, can slide up and down with cursor frame.The front end face of gauge stand 5 is equipped with meter clamper 8, and clamping has dial gauge or clock gauge 11 on the meter clamper 8, and the accurately variation of reflection planes degree guarantees that discrepancy in elevation detection ruler survey measurements is accurate.In order to improve measuring accuracy, the bottom surface of base 1 is shaped on groove 9, with the bottom surface that reduces base 1 and the contact area of backing plate 10 ramps.
Detect principle: after slip cursor frame 3 made dial gauge or clock gauge 11 and the upper surface of platen 12 contacts, vernier scale 6 cooperated with main scale 2 and demonstrates registration, read the high difference size that registration is 1: 40 inclined-plane of backing plate and platen upper surface.The cross bar 4 that horizontally slips, dial gauge or clock gauge 11 registrations change the foozle situation that can reflect 1: 40 inclined-plane of backing plate.
Using method: the bottom surface of base 1 is placed on 1: 40 inclined-plane of backing plate, and 1: 40 inclined-plane start line of base 1 left side and backing plate is alignd, slip cursor frame 3 drives cross bar 4, dial gauge or clock gauge 11 on the gauge stand 5 are contacted with the upper surface of platen 12, this moment, the detection ruler reading was the discrepancy in elevation numerical value of 1: 40 inclined-plane of measurement point backing plate and platen upper surface, slip cross bar 4, dial gauge or clock gauge 11 registrations change can reflect 1: 40 inclined-plane foozle situation.
