Description
技术领域technical field
本申请涉及但不限于轨道交通领域，尤其是一种减振扣件系统。This application relates to but not limited to the field of rail transit, especially a vibration-absorbing fastener system.
背景技术Background technique
近年来，随着以地铁、城际铁路等为代表的轨道交通系统的迅猛发展，城市交通的紧张局面得到了有效缓解；然而，与此同时，这些交通方式带来的振动、噪声污染也给人们的生产生活带来了极大困扰。In recent years, with the rapid development of rail transit systems represented by subways and intercity railways, the tension in urban traffic has been effectively alleviated; however, at the same time, the vibration and noise pollution brought by these transportation methods have also brought People's production and life have brought great troubles.
其中，钢轨扣件作为钢轨与轨枕之间的连接部件，在起到固定钢轨功能的同时，其减振降噪功能也越来越受到人们的重视，目前市场上已经推出了一系列具有减振降噪功能的钢轨扣件产品。在众多减振扣件产品中，可分离式双层减振扣件实现了两层弹性体减振从而达到较高的减振效果，并且可以方便地实现零部件的拆卸更换，因此获得了大量应用，深受市场的青睐。Among them, as the connecting part between the rail and the sleeper, the rail fastener not only has the function of fixing the rail, but also its function of reducing vibration and noise has attracted more and more attention. Rail fastener products with noise reduction function. Among many vibration-damping fastener products, the detachable double-layer vibration-damping fastener realizes two-layer elastic body vibration damping to achieve a high vibration-damping effect, and can easily realize the disassembly and replacement of parts, so it has won a lot of attention. application, favored by the market.
为了实现钢轨扣件的双层弹性体减振，现有技术中的多篇文献公开了不同的技术方案；这些公开的技术方案均是在系统中通过两层铁垫板和两层弹性体相配合实现减振效果。在扣件系统中，上层铁垫板起到承载和固定钢轨作用，锚固道钉旋紧拧入固定在道床基础中的尼龙套管并压紧在下层铁垫板上，从而将扣件系统固定在道床基础上，图1为典型的现有技术结构图。In order to realize the double-layer elastic body vibration reduction of rail fasteners, many documents in the prior art disclose different technical solutions; Cooperate to achieve vibration reduction effect. In the fastener system, the upper iron backing plate plays the role of bearing and fixing the rail, and the anchor spike is screwed into the nylon sleeve fixed in the foundation of the ballast bed and pressed against the lower iron backing plate, thereby fixing the fastener system On the basis of the ballast bed, Fig. 1 is a typical structure diagram of the prior art.
上述现有技术中的技术方案，均能充分发挥两层弹性体的减振功能，实现较高的减振量；然而，在实际使用过程中，仍存在有以下不足：The above-mentioned technical solutions in the prior art can give full play to the damping function of the two-layer elastic body and achieve a higher damping capacity; however, in the actual use process, there are still the following deficiencies:
1，上述双层减振扣件成本高昂；1. The cost of the above-mentioned double-layer damping fasteners is high;
现有技术公开的技术方案中，双层减振扣件均需要两层金属铁垫板，两层铁垫板分别发挥不同的作用；这两层金属铁垫板是整个扣件系统中成本最高的两个部件，占整体成本的70％以上，相对于普通扣件的单层金属垫板来说，额外增加了一层金属垫板，成本上大幅增加。In the technical solutions disclosed in the prior art, the double-layer damping fasteners all need two layers of metal iron backing plates, and the two layers of iron backing plates play different roles respectively; these two layers of metal iron backing plates are the most costly in the entire fastener system The two components account for more than 70% of the overall cost. Compared with the single-layer metal backing plate of ordinary fasteners, an additional layer of metal backing plate is added, which greatly increases the cost.
2，尼龙套管容易发生失效；2. Nylon casing is prone to failure;
现有技术公开的技术方案中，双层减振扣件均通过锚固道钉旋紧拧入尼龙套管中，从而将扣件固定在道床基础上；其中，尼龙套管属于塑料材质，锚固道钉与其螺纹相配合组成的螺纹结构无法承受反复拆卸和拧紧，几次拧紧后尼龙套管的螺纹便出现失效现象，造成扣件无法牢固地固定在道床基础上，给行车安全带来隐患。In the technical solutions disclosed in the prior art, the double-layer vibration-damping fasteners are screwed into the nylon casing by anchor spikes, so that the fasteners are fixed on the foundation of the ballast bed; wherein, the nylon casing is made of plastic material, and the anchor road The thread structure formed by the cooperation of the nail and its thread cannot withstand repeated disassembly and tightening. After several times of tightening, the thread of the nylon sleeve will fail, causing the fastener to be unable to be firmly fixed on the track bed foundation, which will bring hidden dangers to driving safety.
3、钢轨的安装高度较高；3. The installation height of the rail is relatively high;
现有技术公开的技术方案中，双层减振扣件均存在两层金属垫板，扣件高度较高，通常为14mm以上；这将造成钢轨轨底到轨枕面的高度偏高；钢轨的安装高度较高，一方面要求地铁隧道的截面高度增加，从而增加隧道的施工建造成本；另一方面钢轨到轨枕面的高度越高，钢轨的横向稳定性越差，对整个系统的安全性和稳定性带来不利影响。In the technical solutions disclosed in the prior art, there are two layers of metal backing plates in the double-layer damping fasteners, and the height of the fasteners is relatively high, usually above 14mm; this will cause the height from the bottom of the rail to the sleeper surface to be relatively high; The installation height is high. On the one hand, the cross-sectional height of the subway tunnel is required to increase, thereby increasing the construction cost of the tunnel; on the other hand, the higher the height of the rail to the sleeper surface, the worse the lateral stability of the rail, which affects the safety and security of the entire system. Stability is adversely affected.
