Anti-loosening steel rail mounting mechanism and dismounting method thereof
The invention relates to an anti-loosening steel rail mounting mechanism and a dismounting method thereof. The technical problem that an existing rail is poor in installation anti-loosening and vibration reduction effect is solved. The anti-loosening steel rail mounting mechanism comprises a steel rail body arranged on a base, the lower end of the steel rail body is provided with a rail bottom, at least one side of the steel rail body is provided with an elastic fastener through a vibration absorption anti-loosening fastener, the elastic fastener is of a bent-plate-shaped structure, one side of the elastic fastener is provided with fastener openings which are arranged in an up-down staggered mode, and the upper opening portion of each fastener opening of the elastic fastener abuts against the top face of the rail bottom. The lower opening portion of the fastener opening of the elastic fastener abuts against the side face of the rail bottom. The anti-loosening steel rail mounting mechanism has the advantages that the elastic fastener is a U-shaped steel plate, the structure is more reasonable, the anti-vibration and anti-loosening effects are better, and the installation stability is high. The anti-loosening steel rail mounting mechanism can absorb more than 90% of vibration waves, can ensure that the bearing thread sections of the nut and the screw are prevented from being damaged by vibration, is adjustable, detachable and reusable, solves the problem of fatigue and looseness of a bolt shaft core, bears force through full screw and full threads, and enables the bolt load rate to reach 100%.
本发明涉及一种防松退钢轨安装机构及其拆除方法。它解决了现有铁轨安装防松减振效果差等技术问题。包括设置在基座上的钢轨体，钢轨体下端具有轨底部，钢轨体至少一侧通过吸振防松退紧固件设有弹性扣件，弹性扣件呈弯曲板状结构，弹性扣件一侧具有上下错位设置的扣件开口，弹性扣件的扣件开口的上开口部抵靠于轨底部的顶面，弹性扣件的扣件开口的下开口部抵靠于轨底部的侧面。优点在于：弹性扣件为折成U形钢板，结构更合理，防振防松更好，安装稳定性高。生产成本低，可以吸收90％以上振动波，可以确保螺母与螺杆的承力螺纹段免受振动破坏，并且可调可拆可重复使用，解决螺栓轴芯疲劳松弛问题，全螺杆全螺纹承力，使螺栓载荷率达100％。
