Abstract

The utility model relates to a railway steel rail and a connecting piece thereof. Two ends of the steel rail are provided with step joints. Two adjacent steel rails are butt-joint in engagement by the step joints. The connecting piece is arranged between the steel rails. Two engaged step joints are arranged in a groove opening of the connecting piece. The engaged step joints and the connecting piece are fastened together by a fish tail clamping plate and a screw. The utility model makes gap between the two steel rails divided into four tiny length which is staggered to be arranged at different lateral positions. The utility model makes a wheel have no gap experience when the wheel runs on the rail, so the utility model makes vibration and noise obviously reduced.

Description

Railway track and connector thereof

The utility model relates to a kind of railway track and connector thereof.

The laying of railway track, because of the influence of need consideration thermal expansion, the gap must be left in the joint.Shock for train is caused in the gap, and produces noise, and this is the worry of generally acknowledging.Long rail laying can reduce some vibrations and noise, but the cost height, construction is complicated, and need safeguard troop specially.At present, still loseing has feasible measure, solves the trouble that draw in the gap.

The purpose of this utility model is that a kind of rail and connector thereof that the step joint is arranged will be provided.

Utility model is achieved in that at the two ends of rail and is provided with the step joint that adjacent two rails are coincide by the step joint and dock, and connector is arranged between the two rails, the two step joints that match, place in the notch of connector,, the three is fastened as one with fishtail clamping plate and screw.

The utility model makes the gap between the two rails, is divided into 4 very little length, and staggering places different lateral attitudes, and wheel moves on the track, and as gapless impression, vibration and noise significantly reduce.

Introduce the utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model vertical view;

Fig. 2 is the vertical view of connector in the utility model;

Fig. 3 is that the A of Fig. 2 is to view;

Fig. 4 is a steel rail ends position front view in the utility model;

Fig. 5 be in the utility model another embodiment A of connector notch to view.

With reference to accompanying drawing, the end face of connector 3 is equal to the rail end face, and top has notch 4, and waist vertically has a splice bar 5 in aggregates with the connector casting.A step joint 2 is extended on top, termination at general rail 1, and adjacent two joints coincide to join and place in the notch 4, form a level and smooth guide pass of integral body.Two gaps that two gaps that the joint butt joint is reserved and rail and connector are reserved are distributed on the different section of rail, when wheel passes through this section guide rail, always have or not clearance plane supporting wheel, make train vibration influence have or not the gap impression.The cross section of notch 4 is that opening is the trapezoidal of minor face, or is inverted T shape.

Claims

1, a kind of railway track and connector thereof, it is characterized in that: be provided with step joint (2) at the two ends of rail (1), adjacent two rails are coincide by step joint (2) and dock, connector (3) is arranged between the two rails, the two step joints that match, place in the notch (4) of connector, the three is fastened as one with fishtail clamping plate (5) and screw.

2, by described railway track of claim 1 and connector thereof, it is characterized in that: notch (4) cross section of connector (3) is that opening is the trapezoidal of minor face.
