Hinge type structure steel rail joint
The invention discloses a hinge type structure steel rail joint which comprises a first hinge type clamping plate and a second hinge type clamping plate; the first hinge type clamping plate is arranged on the first side of a steel rail, and the second hinge type clamping plate is arranged on the second side of the steel rail. The top of the side face, close to the steel rail, of the first hinge type clamping plate is provided with a first arc face with a preset first arc line, and the first arc face is tightly attached to the inwards-concave circular bead of a rail jaw on the first side of thesteel rail. On the premise that the section of the clamping plates is not increased, the contact surface of the clamping plates and the rail head is increased, the tensile stress borne by the rail head is reduced, damage and failure of the steel rail joint are reduced, and the service life of the steel rail joint is prolonged.
本发明公开了一种铰型结构钢轨接头，所述铰型结构钢轨接头包括第一铰型夹板、第二铰型夹板，所述第一铰型夹板设置在钢轨的第一侧，所述第二铰型夹板设置在钢轨的第二侧，所述第一铰型夹板靠近钢轨的侧面的顶部具有预设的第一弧线的第一弧面，所述第一弧面与钢轨第一侧的轨颚的内凹圆角紧贴设置。本发明在保证夹板断面不增大的前提下，增大了夹板与轨头的接触面，降低了轨头承受的拉应力减少，减少了钢轨接头伤损失效，提高了钢轨接头使用寿命。
