Damping fastener with rail brace in turnout zone
The invention provides a damping fastener with a rail brace in a turnout zone. The turnout zone vibration reduction fastener with the rail brace comprises a base plate assembly; the rail brace and the stock rail are arranged on the base plate assembly, the rail brace and the stock rail are arranged on the outer sides of the rail brace and the stock rail, the side, facing the stock rail, of the rail brace is provided with a cushion layer, and the cushion layer at least covers at least one of the lower jaw area, the rail waist area and the rail bottom area of the stock rail; the sliding bed platen is arranged on the base plate assembly and abuts against the side, away from the rail brace, of the stock rail, and a switch rail is arranged on the sliding bed platen; the number of the transverse limiting blocks is at least two, and at least one part of each transverse limiting block is arranged in the base plate assembly; and at least one part of the first fixing assembly sequentially penetrates through the rail brace and the base plate assembly. The problems that in the prior art, the vibration noise of a turnout zone of urban rail transit is too large, and the rail piece stability is poor after a vibration reduction fastener is adopted are solved.
本发明提供了一种道岔区带轨撑减振扣件。道岔区带轨撑减振扣件包括：垫板组件；轨撑，轨撑和基本轨分别设置在垫板组件上，轨撑与基本轨的外侧，且轨撑朝向基本轨的一侧具有垫层，垫层至少覆盖基本轨的下颚区域、轨腰区域、轨底区域中的至少一个区域；滑床台板，滑床台板设置在垫板组件上并与基本轨远离轨撑的一侧抵接，且滑床台板上设置有尖轨；横向限位块，横向限位块为至少两个，横向限位块的至少一部分设置在垫板组件的内部；第一固定组件，第一固定组件的至少一部分依次穿过轨撑和垫板组件。本发明解决了现有技术中城市轨道交通道岔区振动噪声过大以及采用减振扣件后轨件稳定性差的问题。
