Embodiment Construction

[0028] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 , figure 2 with image 3 As shown, the reinforced track damping fastener of this embodiment includes a short sleeper 15, and the lower iron backing plate 8 and the under-board backing plate 10 are anchored on the short sleeper 15 through the lower thread of the stud bolt 13, and the under-board backing plate The plate 10 is located at the bottom of the lower iron backing plate 8, the two ends of the lower backing plate 10 and the lower iron backing plate 8 are respectively slotted, and elastic sliding sleeves 9 are respectively installed in the slots; the upper surface of the lower iron backing plate 8 The floating iron backing plate 6 is installed through the vibration-isolation rubber backing plate 7. The bottom of the floating iron backing plate 6 is provided with a wedge-shaped shoulder 604. The wedge-shaped ...

Abstract

Provided is a reinforced rail vibration-damping fastener. A lower iron backing plate and a lower backing plate are anchored on a sleeper through a thread at the lower end of a stud, a floating iron backing plate is disposed on the upper portion of the lower iron backing plate, a vibration isolation rubber pad plate is mounted between the floating iron backing plate and the lower iron backing plate, the floating iron backing plate and the lower iron backing plate are in the vertical direction of a steel rail, and two elastic guide assemblies are disposed parallel to the two sides of the steel rail respectively. Two wedge-shaped blocking shoulders extend at the bottom of the floating iron backing plate, and the wedge-shaped blocking shoulders are inserted in and matched with elastic slidingsleeves in corresponding rectangular groove holes of the lower iron backing plate, to perform limiting in the vertical and horizontal direction of the steel rail and slide up and down. Through an insulating bushing, a compression spring and a locknut, four through holes in the floating iron backing plate sleeve the upper end of the stud. The steel rail buckles the floating iron backing plate in alimiting mode through an under-rail rubber backing plate, an insulating rail cushion block, a T-shaped bolt, a nut and an elastic strip. On the whole, the reinforced rail vibration-damping fastener achieves high vibration damping capacity, and the use reliability is greatly improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a reinforced rail vibration-damping fastener. Background technique [0002] While urban rail transit brings convenience to people's travel, the wheel-rail coupling vibration also brings vibration and noise pollution to surrounding buildings. The use of vibration reduction on the track is one of the effective measures to reduce the surrounding environment and noise. However, the damping performance and lateral rigidity of various damping fasteners in the prior art are not ideal. Contents of the invention [0003] Aiming at some shortcomings of the above-mentioned existing damping fasteners, the applicant provides a reinforced track damping fastener. By reducing the damping stiffness of the rail fastener and increasing the lateral stiffness and deflection stiffness of the fastener, the buckle The fastener can not only have high vibration damping performance, but also effec...
