Steel rail connecting device for strengthening steel rail tipping rigidity and controlling steel rail wavy abrasion
The invention discloses a steel rail connecting device for strengthening steel rail tipping rigidity and controlling steel rail wavy abrasion, which comprises a plurality of anti-bending cross beams positioned at the bottoms of two steel rails, the plurality of anti-bending cross beams are arranged at intervals, and an inner buckling plate and an outer buckling plate are respectively arranged on two sides of each steel rail. The inner buckling and pressing plate and the outer buckling and pressing plate are positioned on the upper end face of the anti-bending beam and clamp the rail bottom of the steel rail between the inner buckling and pressing plate and the outer buckling and pressing plate, the inner buckling and pressing plate and the anti-bending beam are connected through buckling and pressing bolts, and the outer buckling and pressing plate and the anti-bending beam are connected through buckling and pressing bolts. The transverse relative sliding speed of a wheel tread and the top surface of the steel rail can be effectively reduced through reduction of transverse displacement of the top surface of the steel rail, wheel-rail creep entering a negative gradient area is reduced, and therefore wheel-rail creep self-excited vibration is reduced or avoided, wavy abrasion of the steel rail is relieved, wheel-rail noise and foundation vibration are reduced, and the service lives of the wheel, the steel rail and the fastener are prolonged.
本发明公开了一种强化钢轨倾翻刚度控制钢轨波浪形磨耗的钢轨连接装置，包括位于两个钢轨底部的多个抗弯横梁，多个抗弯横梁间隔开布置，每个钢轨的两侧分别设置有内扣压板和外扣压板，内扣压板和外扣压板定位在抗弯横梁上端面，内扣压板和外扣压板将钢轨的轨底夹紧在内扣压板和外扣压板之间，内扣压板与抗弯横梁之间、外扣压板与抗弯横梁之间通过扣压螺栓连接。本发明钢轨顶面横向位移的降低会有效减小车轮踏面和钢轨顶面的横向相对滑动速度，减少轮轨蠕滑进入负梯度区域，从而减少或避免轮轨蠕滑自激振动的发生，减轻钢轨波浪形磨耗并降低轮轨噪声和地基振动，提高车轮、钢轨及扣件的使用寿命。
