Abstract
The utility model relates to a steel rail line with inclined slit ends, the task of which is to solve the problems that the line connection of steel rails and wheels is changed into surface connection, and shock and noise are generated by the falling of steel rail ends. The method of the utility model is that the rail end surface is provided with two symmetrical inclined plane surfaces which are coincident with the wheel tread I, and the seams are supported by rail sleeper plates and fixed by four fasteners.
Description
What the present invention proposed is a kind of R-joining steel rail line.
The past people once adopted gapless track to reduce the vibrations and the noise of train, but this gapless track not only lay, difficult in maintenance, and normal because of bloated rail, runway causes overturns train.The someone proposes by improving common line, to reach the purpose of damping now.Through looking into, " novel angle stake railway track " that China patent CN85200917U proposes solved vibrations and noise that the interface slit is produced to a certain extent.But because wheel and the rail of operation are the line contact conditions, be discontinuous contact at seam crossing, gap place sleeper adopts hanging type in addition, wheel by the time easily cause rail end whereabouts.The vibrations of novel like this angle stake railway track and noise are still bigger.
Task of the present invention is the angle stake railway track to be contacted with the line of wheel tread change the face contact into, solves the gap place simultaneously because of the unsettled rail end whereabouts problem that causes, with vibrations and the noise that further reduces train.
Realizing method of the present invention, is the tapered plane (3) that the cambered surface of rail head of rail face is changed into symmetry, and the tapered plane (3) of rail head and wheel tread I (2) are matched.When wheel (1) reached the top of rail the last period with the face contact, wheel also on the end of back one section rail, when cartwheel roll is crossed R-joining (9) like this, was in the Continuous Contact state, can reduce the vibrations of the sort of discontinuous contact.For increasing the application life of rail, make rail have interchangeability, two tapered planes of rail head face should with rail axis symmetry, locate with concrete slab sleeper (8) rim in rail mitre (9), and fixing with four fasteners (7), fall to prevent seam crossing rail end when loading.
R-joining steel rail line of the present invention promptly has common line, the rail convenient transportation, track laying, maintenance, method for maintaining are simple, can avoid the expand generation of rail, runway accident of circuit, have the driving of gapless track steady again, the visitor of family is comfortable, reduces vibrations, prolong the application life of bridge, locomotive and vehicle, be suitable for advantages such as high speed traveling.The R-joining steel rail line is because of locating to have adopted concrete slab sleeper (8) rim in seam (7), four fasteners (7) are fixing, also can avoid the rail end to fall, and has further reinforced being connected between rail and the rail.
Embodiment is as shown in drawings:
Fig. 1 is the front view that rail contacts with wheel.
Fig. 2 is the A-A sectional view of Fig. 1.
The gradient of the symmetrical tapered plane (3) of rail (4) is according to the gradient value of the wheel tread I (2) of rail cant (6) and wheel (1).Because the gradient ratio of common rail cant (6) is 1:40.The gradient ratio of wheel tread I (2) is 1:20.So the gradient ratio of rail tapered plane (3) is got 1:40, tapered plane (3) and wheel tread I (2) are matched.(5) be the wheel tread II.Do not mark between two tapered planes among the figure, the rail centerline is the garden slip.In present embodiment Fig. 2, the angle of rail R-joining (9) is got 45 °, and by concrete slab sleeper (8) rim, four fasteners (7) are fixing under the R-joining (9).
Claims (2)
1, a kind of R-joining steel rail line is characterized in that the rail head face has the tapered plane of two symmetries, and the gap place is by the concrete slab sleeper rim, and four fasteners are fixed.
2, R-joining circuit as claimed in claim 1 is characterized in that the gradient ratio of rail head tapered plane is 1:40.
