Abstract
The utility model relates to a railway steel rail attachment joint which is formed by fixation of end portions of two adjacent steel rails through a steel rail connection clamp plate. A connection end face of the steel rail is oblique. The steel rail connection clamp plate is provided with a dovetail groove which holds a dovetail portion of the steel rail. According to the railway steel rail attachment joint, connection gaps between the steel rails can be reduced, welding is needless, expansion and contraction are free, noise of a train in operation is reduced, passengers on the train feel stable and comfortable, and accordingly an ideal effect is achieved.
Description
Technical field
The utility model belongs to train operation track in the railway transportation, and what be specifically related to is the railway track jointing.
Background technology
Rail is the element of railway, and rail couples together and forms long railway one by one, and two rails couple together by connector.Two connecting end surfaces of existing railway track are vertical with respect to the rail body, and rail interconnects rear connecting sewing and rail is an angle of 90 degrees, and connecting sewing is to be the solution problem of expanding with heat and contract with cold, the space of leaving in the rail junction.When train travels at rail, because the termination of two adjacent rails is concordant, when up to a hundred wheels pass through the rail junction, can produce resistance, vibration force, make train produce vibrations, send the sound of bang bang, also affect the life-span of wheel.
Summary of the invention
The purpose of this utility model provides the railway track jointing, and it is used for solving the problem that the train vibrations that existing rail syndeton causes are large, send noise.
The technical scheme that its technical problem that solves the utility model adopts is: this railway track jointing is fixed together the end of adjacent two rail by the rail connecting cleat and forms, the connecting end surface of rail is oblique, the rail connecting cleat is with dovetail groove, and dovetail groove is accommodated in the inner the dovetail position of rail.
The connecting end surface of rail is tapered plane in the such scheme.
The connecting end surface of rail is skew curve shape in the such scheme.
The connecting end surface of rail is the sloping platform scalariform in the such scheme.
Beneficial effect:
The utility model is fixed therein adjacent two rail with oblique section by the rail connecting cleat of both sides, connecting sewing between rail is little, need not welding, capable of expansion and contraction, reached the effect of expanding with heat and contract with cold, avoided train wheel and straight shape Rail joint head to bump, make train reduce resistance, shaking force, little to the damage of wheel, reduce the noise that train is in operation, it is more steady, more comfortable that the passenger feels by bus, thereby reached more satisfactory effect.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, this railway track jointing is fixed together the end of adjacent two rail 1 by rail connecting cleat 2 and forms, the connecting end surface of rail 1 is oblique, in conjunction with shown in Figure 2, the connecting end surface of rail 1 is tapered plane in the present embodiment, adopting this connecting end surface is the rail 1 of tapered plane, and it is R-joining that rail 1 interconnects rear connecting sewing, the Distance Shortened of the more original vertical masonry joint of spacing of this R-joining 2 millimeters.Consult shown in Figure 5, rail connecting cleat 2 is with dovetail groove 3, rail connecting cleat 2 is positioned at the both sides of two rail 1 and is arranged on the connecting portion place of two rail 1, specifically the straight plate part position of rail connecting cleat 2 is positioned at the web of the rail 4 positions of rail, the dovetail position flange of rail 5 of rail is in the dovetail groove 3 of rail connecting cleat, on the rail 1 bolt hole is arranged, bolt hole is also arranged on the rail connecting cleat 2, rail connecting cleat 2 is fixed together by bolt 6 with rail 1.
Fig. 3 is the structural representation of two adjacent track bonds in the utility model the second embodiment, as shown in the figure, this railway track jointing is fixed together the end of adjacent two rail 1 by rail connecting cleat 2 and forms, and the connecting end surface of rail 1 is skew curve shape.Other structure is identical with the first embodiment.
Fig. 4 is the structural representation of two adjacent track bonds in the third embodiment of the utility model, as shown in the figure, this railway track jointing is fixed together the end of adjacent two rail 1 by rail connecting cleat 2 and forms, and the connecting end surface of rail 1 is the sloping platform scalariform.Other structure is identical with the first embodiment.The step of the connecting end surface both sides of this rail 1 is vertical with the rail body, and two steps connect transition by middle inclined-plane.
