Abstract

The utility model provides a railway rail with inclined joints. At joint of two rails, each connector employs a semi-rail, and a joint in the position of a web is an inclined joint. An included angle formed between the joint and the rail direction is 20-70 degrees. The railway rail with inclined joints has the advantages of fully incorporating flexibility of existing railway rail, because the cross-connecting position of two rails are still provided with a joint with certain width, when the railway rail produces cold and hot extension, rails on two sides of the joint can be freely flexible, and deformation of the two rails are ensured to be avoided, 2 rails keep good tangential relationship with wheels when wheels pass the rails, thereby local impact to the rail end is decreased, and damages of wheels and local surface of rails are reduced, 3 noise and jolt produced by train wheels in the position of the joint are eliminated, which is favorable for wheels acceleration and stability in running process.

Description

The rail of oblique seam

Technical field

The utility model relates to a kind of rail of oblique seam.

Background technology

Expand with heat and contract with cold in order to guarantee that rail can be finished effectively fully under nature, and do not cause adjacent double track to push mutually, it is excessive to make that parallel error takes place parallel double track, so that derailing incident etc. occurs.So, can in its scope, freely stretch to guarantee both sides, slit rail in the general simple reservation parallel slit of adopting of rail seam crossing.In the prior art scheme, the rail seam is all perpendicular with rail.Its weak point is: during train process rail seam, can cause greater impact to the rail seam crossing, cause the rail end damage on the one hand, also can produce tangible vibration and noise on the other hand.During the seam broad, above-mentioned defective is especially obvious in the winter time.

The utility model content

The purpose of this utility model is to provide a kind of rail of oblique seam, can effectively improve the railway globality to reach on the telescopic basis of the original rail flat seam of compatibility, and smoothness and reduction are to rail local failure purpose in the raising train running process.

The rail of a kind of oblique seam described in the utility model, oblique seam promptly adopt half rail at two each joint of rail seam crossing, and the seam at web place is the interlaced formation oblique gap of two halves rail.Angle between seam and the orbital direction be 20～70 the degree, with two track flush joint lines not conllinear be the angle greatest limit.

The advantage of the rail of a kind of oblique seam described in the utility model is: 1, can be fully the scalability of compatible existing rail, because two rail junctions still possess the seam of proper width, so run into cold and hot when flexible at rail, seam both sides rail can freely stretch, and guarantees that double track is indeformable.2, wheel keeps tangent relation preferably at seam crossing between out-of-date track and wheel, and place's local assault will diminish for the rail end, has reduced the damage of wheel and rail local surfaces.3, eliminated wheel and jolted at seam crossing generation noise and concussion, steady in favourable wheel speed-raising and the traveling process.

Below in conjunction with drawings and Examples the utility model is further described.

Description of drawings

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the structural representation of another embodiment of the present utility model;

The specific embodiment

Embodiment one: the structure of the rail of a kind of oblique seam described in the utility model as shown in Figure 1, the seam between rail 1 and the rail 2 is an oblique seam, its angle of slope a be 30 the degree.

Embodiment two: the structure of the rail of a kind of oblique seam described in the utility model as shown in Figure 2, seam between rail 1 and the rail 2 is a broken line shape, this broken line two end portions is the edge of a wing 11 of the corresponding rail left and right sides respectively, flush joint length is 10-20mm apart from edge, and its direction is vertical with orbital direction, the position of the corresponding rail web 12 in the stage casing of this broken line, and be 45 degree with respect to the angle of slope a of orbital direction.

Its course of work is:

During wheel process seam crossing, at first arrive the flush joint at place, the edge of a wing, right side, and quite big line load is pressed on the edge of a wing and the web place of track 1 in the wheel width, this moment, wheel load can be conducted to web by frange plate normally, even when entering gaping of joints, also just the small part wheel load is in unsettledly, will make not produce tangible concussion and bigger jolting not influencing under the normally stressed situation of rail itself like this.

When the flush joint of wheel by the edge of a wing, right side place, when arriving the R-joining at web place, wheel produces line load with seam generation overlapping relation rather than parallel relation, gradually by rail 1 to rail 2 transition.

When wheel arrives the R-joining mid point is two rail critical conditions, behind the equal critical state of arrival, finishes gradually by the transition of rail 1 to rail 2.

When wheel arrived the flush joint at place, the edge of a wing, left side, quite big line load was pressed on the edge of a wing and the web place of track 2 in the wheel width.
