Steel rail joint rail gap compensation structure and rail
The invention discloses a steel rail joint rail gap compensation structure and a rail. The steel rail joint rail gap compensation structure is installed between rail joints of two steel rails, each steel rail is provided with a rail head, the two steel rails are connected through a rail clamping plate, the steel rails are used for bearing a train, and the steel rail joint rail gap compensation structure comprises a base, a top cover and a connecting part. The two ends of the base are detachably connected with the two steel rails respectively. The shape of the cross section of the top cover isthe same as that of the cross section of the rail head, the top cover and the rail head are located at the same height, the top cover is connected to the upper portion of the base in a sliding mode, the two ends of the top cover make contact with the two rail heads respectively, and the top cover is made of materials with thermal shrinkage and cold expansion characteristics. The connecting part isrespectively connected with the rail clamping plate and the top cover, is made of a material with thermal expansion and cold contraction characteristics, and is used for enabling the top cover and the two rail heads to be flush with the contact surface of the train. Rail joints between steel rails are eliminated, and therefore the problem that in the prior art, due to the existence of the rail joints, a rail structure is discontinuous is solved.
本发明公开了一种钢轨接头轨缝补偿结构即铁轨，该钢轨接头轨缝补偿结构安装于两个钢轨的轨缝之间，钢轨具有轨头，两个钢轨通过轨道夹板连接，钢轨用于承载列车，钢轨接头轨缝补偿结构包括基座、顶盖和联结部。基座的两端分别和两个钢轨可拆卸连接。顶盖的横截面的形状和轨头的横断面的形状相同，且顶盖和轨头位于同一高度，顶盖滑动连接于基座上方，顶盖的两端分别和两个轨头接触，顶盖的材质为具有热缩冷胀特性的材质。联结部分别与轨道夹板和顶盖连接，联结部的材质为具有热胀冷缩特性的材质，用于使顶盖和两个轨头在与列车的接触面处平齐。本发明消除了钢轨之间的轨缝，从而解决了现有技术中因为轨缝的存在而导致轨道结构不连续的问题。
