Abstract

The utility model relates to an angular interface joint for a railway of a train, which comprises a rail head 1, a rail wall 2 and a rail bottom 3. Joint positions are from top to down cut into angular interface joints of the same oblique angle. The front end of the rail tip of the rail head 1 is made into a buffering slope surface by effective length. Two edges of the rail bottom are cut into foldback oblique surfaces. The utility model can effectively play a buffering action, lighten impact resistance, reach the purpose of raising speed due to the adoption of the angular interface rail joint and reduce transportation costs. The utility model is favorable to the safe and high-speed running of the train. The utility model has the advantages of novel design, reasonable structure, high safety and reliability, good vibration damping performance, easy reconstruction and convenient installation.

Description

Oblique type train track rail joint

The utility model relates to a kind of oblique type train track rail joint, belongs to transportation class.

At present in the new century of high-tech develop rapidly, track makes long rail into by original short rail, its joint area still is vertical transverse plane, when the train fast running lacks smooth transition during to joint area, because of pressurized section joint area sinks, certainly lead to next joint joint is seriously clashed into, and send the high-frequency impact sound, reduced train wheel and splice bar application life.

The purpose of this utility model is to provide a kind of oblique type train track rail joint, and this kind joint can play cushioning effect, and smooth transition alleviates the bump resistance of joint area, reduces mechanical wear, prolongs the application life of train wheel and splice bar.

The purpose of this utility model is to realize like this.It comprises rail head (1), rail wall (2), (3) three parts of the flange of rail, and at the joint area inclined stubble surface joint that is cut into same angle of slope from top to bottom, the rail crack tip of rail head (1) is made the buffering slope with effective length, is cut into the inclined-plane that turns back on flange of rail both sides.

During installation, left and right two oblique batches of joints are put relatively, connect into track by the flexible requirement of specification, overall fixed is good, just use can put into operation, whenever train fast running during to the joint expansion slit, each wheel of train is under oblique stubble condition, car body weight in advance with preceding plane tie rail point on domatic contact of buffering, car body weight gets on for preceding root track by light extremely heavy smooth transition, because the domatic effect of efficient buffer on the rail point, each wheel of train are contracted by track rail joint smoothly in not having the bump resistance and are stretched the slit.

The utility model can effectively play cushioning effect owing to adopt the oblique type track rail joint, alleviates the bump resistance, reaches speed-raising, be suitable for the safety high speed operation, reduce cost of transportation, increase economic efficiency its modern design, rational in infrastructure, safety is reliable, and damping property is good.Be easy to transform, easy for installation, be suitable for and apply.

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

Fig. 2 is its vertical view.

Below in conjunction with accompanying drawing enforcement of the present utility model is described further:

Implement 1: as shown in the figure, when the utility model is made, make of the general heavy rail of country, at rail head 1, rail wall 2, the flange of rail 3 inclined stubble surface joint that is cut into same oblique angle from top to bottom, rail head position inclined stubble surface angle be 20 ° the most moderate, making the domatic angle of buffering at the rail crack tip with 60mm is 16 °, and plane of structure is cut on flange of rail both sides or folding angled end-face angle is 30 °.Make 8 in rail hole at rail wall 3, thickening 30mm to 35mm two is 2.5cm in the middle of the splice bar, and is fixedly connected with 8 bolts with 1 meter long, guarantees long rail pulling force.With 1 meter long on the thick channel-section steel backing plate of 15mm, encrypting on the ash pillow, in the application life for the protection splice bar, require thick middle 15mm along flange of rail pad.Other all specifications are the same with common track.

Implement 2: when the utility model is made, make of the general heavy rail of country, at rail head 1, rail wall 2, the flange of rail 3 inclined stubble surface joint that is cut into same oblique angle from top to bottom, in rail head position inclined stubble surface angle is 12 °, making the domatic angle of buffering at the rail crack tip with 90mm is 5 °, and it is 90 ° that the angled end-face angle is cut on flange of rail both sides.

Implement 3: when the utility model is made, make of the general heavy rail of country, at rail head 1, rail wall 2, the flange of rail 3 inclined stubble surface joint that is cut into same oblique angle from top to bottom, in rail head position inclined stubble surface angle is 60 °, making the domatic angle of buffering at the rail crack tip with 30mm is 45 °, and it is 45 ° that folding angled end-face angle is cut on flange of rail both sides.
