Description
Technical Field
The utility model relates to a orbital technical field, more specifically say so and relate to technical field of rail for railway.
Background
Railway rails, which are referred to as rails, tracks, etc., are used on railways. It is usually made up of two parallel rails fixed to sleepers, under which ballast is located. Rails are the primary load bearing structure of a railroad track used to guide the rolling stock while providing a minimal resistance contact surface for the rolling wheels. The steel rail is required to have sufficient bearing capacity, bending strength, fracture toughness, stability and corrosion resistance. The length of the steel rail used by the common railway is 12.5 meters, the joint of the steel rail and the steel rail is effectively connected by adopting a connecting piece, the steel rail connecting piece mainly comprises a clamping plate and a bolt, the steel rail connecting piece is used for connecting the steel rail at the joint, the joint part of the steel rail has the same integrity as the steel rail so as to resist bending and displacement, and the joint part also meets the requirement of steel rail expansion. Because the clamping plates of the existing steel rail connecting piece only can play a role in connection, a certain gap is formed at the joint of the two steel rails, when the train wheels pass by, the sound of 'rattling' is inevitably generated, and the comfort of passengers riding the train is influenced. In addition, the speed of the train is limited due to the existing rail structure.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a maximum reduction rail joint clearance in order to solve above-mentioned not enough, promote the passenger and take advantage of the travelling comfort, still be favorable to the novel railway rail structure of train speed-up.
The utility model discloses a solve above-mentioned technical problem, and the technical solution who adopts as follows:
a novel railway steel rail structure comprises a first steel rail, a second steel rail, a first clamping plate, a second clamping plate and bolts, a first notch is arranged on the side surface of the first steel rail, a second notch is arranged on the same side surface of the second steel rail, the first clamping plate is positioned at the splicing position of the first notch and the second notch, the first clamping plate is matched with the splicing surfaces of the first notch and the second notch, the upper surface of the first clamping plate is flush with the upper surfaces of the first steel rail and the second steel rail, the first steel rail and the second steel rail are respectively provided with a connecting hole, the first clamping plate and the second clamping plate are respectively provided with a corresponding connecting hole, the second clamping plate is positioned at the other side of the first steel rail and the second steel rail, and the first clamping plate and the second clamping plate are fixedly clamped at two sides of the first steel rail and the second steel rail through bolts.
The cross section of the first notch is in a right trapezoid shape, the cross section of the second notch is in an opposite right trapezoid shape, and the cross section of the first clamping plate is in an isosceles trapezoid shape.
The first clamping plate and the second clamping plate are respectively provided with corresponding connecting holes which are in an elliptical shape.
An elastic washer is sleeved on the bolt.
The utility model adopts the beneficial effect that above-mentioned technical solution can reach is: the notches are formed in the side faces of the first steel rail and the second steel rail, the clamping plate is fixedly clamped at the formed notches, and the height of the clamping plate is consistent with that of the steel rails, so that when the steel rail clamping device is installed, the gap between the joints of the two steel rails can be reduced to the maximum extent, the clicking sound generated when a train runs through the steel rail clamping device is reduced, and the riding comfort of passengers is improved. Through changing the shape structure of rail and splint, can evenly divide the clearance of two rail joints to the contact department of splint both ends and rail, reduced the clearance, just also reduced the sound that wheel walking clearance department produced. Due to the change of the steel rail structure, conditions are created for accelerating the speed of the train.

Detailed Description
As shown in fig. 1, 2 and 3, a novel railway rail structure comprises a first rail 1, a second rail 2, a first clamping plate 3, a second clamping plate 4 and a bolt 5, wherein a first notch 6 is formed in a side surface of the first rail 1, a second notch 7 is formed in the same side surface of the second rail 2, the first clamping plate 3 is located at a splicing position of the first notch 6 and the second notch 7, the first clamping plate 3 is matched with the splicing surfaces of the first notch 6 and the second notch 7, an upper surface 8 of the first clamping plate 3 is flush with upper surfaces 9 of the first rail 1 and the second rail 2, namely the notches of the first rail 1 and the second rail 2 are filled by the first clamping plate 3, contact positions with the first rail 1 and the second rail 2 are respectively formed at two ends of the first clamping plate 3, and the contact surfaces can be inclined surfaces or other irregular curved surfaces, therefore, when the train wheels pass by, the train wheels cannot contact with the cross section of the gap at the same time, but contact with the cross section gradually, so that the noise generated during contact is effectively reduced, and the aim of improving the riding comfort of passengers is fulfilled. Of course, for the sake of simplicity of processing and installation, the first recess 6 has a right trapezoid cross section, the second recess 7 has an opposite right trapezoid cross section, and the first clamping plate 3 has an isosceles trapezoid cross section. Connecting holes are respectively formed in the first steel rail 1 and the second steel rail 2, corresponding connecting holes are respectively formed in the first clamping plate 3 and the second clamping plate 4, the second clamping plate 4 is located on the other side of the first steel rail 1 and the other side of the second steel rail 2, and the first clamping plate 3 and the second clamping plate 4 are fixedly clamped on two sides of the first steel rail 1 and the second steel rail 2 through bolts 5. In order to adapt to the self-adjusting function of the steel rail during expansion and contraction, the first clamping plate 3 and the second clamping plate 4 are respectively provided with corresponding connecting holes which are in an elliptical shape. In order to improve the anti-seismic and anti-loosening performance of the steel rail, an elastic washer is sleeved on the bolt 5.
