Equipped with registration holes 21, the second side plate 3 is equipped with size matched contraposition column 31 corresponding with registration holes 21.21 He of registration holes
The position central point O of column 31 is aligned, it is on the longitudinal axis where its two waists extending line intersection point of isosceles trapezoid X and certain with the intersection point
It is worth on the fixed position of distance H.Due to dimensional discrepancy problem, the longitudinal axis not necessarily with the middle overlapping of axles of isosceles trapezoid, this case
A key technology point be to use the longitudinal axis for reference, and not axis.In specific embodiment, 2 company of being welded on of the first side plate
It connects in the first end face 121 of vertical part 12, the second side plate 3 is welded in the second end face 122 of connection vertical part 12, in this second side plate
Contraposition column 31 on 3 is corresponding hidden set on 112 lower section of splice sections, is conducive to rail carry and keeps track key position intact
Effect.Further, the isosceles trapezoid of the position its central point O of registration holes 21 institute reference for rail level portion 11 21 institute of correspondence registration holes
Endface position at end, corresponding specific embodiment, the position its central point O of registration holes 21 institute is with reference to its first end of rail level portion 11
The isosceles trapezoidal structure of 111 position of face；Similarly, the isosceles trapezoid for aligning the reference of the position its central point O of column 31 institute is rail level portion 11
Corresponding contraposition 31 place end of column endface position, corresponding specific embodiment, the contraposition position its central point O of column 31 institute with reference to
The isosceles trapezoidal structure of its 112 free end face position of splice sections of rail level portion 11.It is designed in this way, avoiding track both ends, there are certain
The dimensional discrepancy of degree matches the first side plate 2 and the second side plate 3 mutually precisely with respective respective carter end, it is ensured that obtained
So the both ends connectivity of track is precisely effective respectively.
Preferably, the first side plate 2 and the second side plate 3 are also respectively provided with corresponding locking hole 22,32.Locking hole 22,
32 are used to lock two rail effects mutually spliced.Further, the locking hole on first side plate 2 is equipped with and is positioned horizontally in registration holes
Two holes of 21 left and right sides, the locking hole 23 on the second side plate 3 are equipped with two holes for being positioned horizontally in contraposition 31 two sides of column.Symmetrically
Two hole groups design, conducive to promoted locking steady reliability.
This case also proposes a kind of calibration assemble method of mining rail, and its step are as follows:
1) cross section is manufactured in I-shaped I-rail ontology 1；The structure of the I-rail ontology 1 referring to above-mentioned, this
It is stated without thunder at place.
Preferably, be manufactured after the I-rail ontology 1, the orbital plane also to its rail level portion 11 of I-rail ontology 1
110 make the orthopedic processing of isosceles, the orthopedic processing of the isosceles of especially end positions；To the first end face 111 in rail level portion 11 and second
Make the orthopedic processing of vertical plane in end face 112；In this way, be conducive to subsequent step 3) in correction assembly operation.
2) the first side plate 2 and the second side plate 3 are manufactured, the structure of first side plate 2 and the second side plate 3 referring to above-mentioned,
It is stated herein without thunder.
3) the first side plate 2 and the second side plate 3 are respectively welded in the both ends of the surface of connection vertical part 12, wherein welding Shi Xianfen
It Ding Dian not determine registration holes 21 and align the position correction center point O of column 31, as shown in figure 5, the position correction center point O is abided by
The correcting mode followed are as follows: the longitudinal axis where its two waists extending line intersection point of 110 isosceles trapezoid of orbital plane X is determined, on the longitudinal axis
With the fixed position of the certain distance H value of intersection point X, which must be on the end face of connection vertical part 12.
Specific embodiment is provided, the distance H value is 71.9mm.The angle a of two waists of isosceles trapezoid is 120 degree.
Preferably, in the step 3), the first side plate 2 is welded in the first end face 121 of connection vertical part 12, second side
Plate 3 is welded in the second end face 122 of connection vertical part 12.
Due to dimensional discrepancy problem, the longitudinal axis is not necessarily overlapped with the central axes of isosceles trapezoid, and the one of this case is crucial
Technical point is to use the specific longitudinal axis for reference, and not central axes.Preferably, in the step 3), registration holes 21 its
The isosceles trapezoid of the position correction center point O institute reference is the endface position at the 21 place end of correspondence registration holes in rail level portion 11, corresponding
Specific embodiment, the position its correction center point O of registration holes 21 with reference to its 111 position of first end face of rail level portion 11 isosceles
Trapezium structure；Similarly, the isosceles trapezoid for aligning the reference of the position its correction center point O of column 31 institute is the corresponding contraposition in rail level portion 11
The endface position at 31 place end of column, corresponding specific embodiment, the contraposition position its correction center point O of column 31 institute is with reference to rail level portion
The isosceles trapezoidal structure of 11 its 112 free end face position of splice sections.
Preferably, in the step 3), in also offering corresponding locking respectively on the first side plate 2 and the second side plate 3
Hole 22,32.Specific embodiment, the locking hole on the first side plate 2 are equipped with two holes for being positioned horizontally in 21 left and right sides of registration holes, the
Locking hole 23 on two side plates 3 is equipped with two holes for being positioned horizontally in contraposition 31 two sides of column.
When mining rail splices assembling at the scene, as shown in figure 4, by with 2 end of the first side plate of track and another track
The matching docking of second side plate, 3 end realizes simple reliably one locking again by locking hole 22,32 later, thus according to reality
Needed length sequentially continuously splices, in assembling process, without for splicing alignment issues carry out complicated and cumbersome adjustment,
The operations such as measurement, detection, assembling is very simple, convenient, accurate, at low cost.
The above description is only a preferred embodiment of the present invention, all equivalent changes done with scope of the invention as claimed and
Modification, should belong to the range of the claims in the present invention.
