Problems solved by technology

[0006] 1. The pre-embedded double-layer vibration damping fastener system in the existing technical scheme cannot be pre-assembled before leaving the factory like the double-layer vibration damping. There are many parts, which increases the construction difficulty to a certain extent, and also virtually Increase the installation cost of the product and reduce the market competitiveness of the product
[0007] 2. In actual use, there are still a series of problems such as high cost, easy failure of nylon sleeve, and high installation height

Embodiment 1

[0047] figure 1 It is the general assembly drawing of the rail damping fastener of Embodiment 1 of the present invention, such as figure 1As mentioned above, the damping fastener of the present invention includes a rail bearing plate 2, an elastic pad 3, a positioning boss 4, a concrete sleeper 5, a locking nylon sleeve 6, a locking cover plate 7, bolts 8, nuts 9, spring washers 10. Elastic bar 11 and insulating gauge block 12; wherein, the bottom of the positioning boss 4 is buried in the track foundation, and the top of the positioning boss 4 is a hollow boss structure. The rail bearing plate 2, the elastic pad 3 and the locking nylon sleeve 6 are pre-assembled structures, and the pre-assembled structure passes through the boss structure on the top of the positioning boss 4 and is arranged on the track foundation. The locking cover plate 7 is arranged on the top of the positioning boss 4 and the locking nylon sleeve 6, the bolt 8 is arranged in the hollow cavity of the posi...

Embodiment 2

[0068] What needs to be mentioned is that if Figure 6 The shown structure schematic diagram of the adhesive backing plate involved in the track damping fastener of the second embodiment of the present invention, combined with Figure 1-Figure 6 , this embodiment provides a rail damping fastener, the difference from Embodiment 1 lies in the connection mode of the elastic pad 3 and the rail support plate 2, in the second embodiment, the connection mode of the elastic pad 3 and the rail support plate 2 is Vulcanization and bonding to form a bonding backing plate 13, the bonding backing plate 13 includes an under-rail pad 131 and an under-board pad 132, wherein the under-rail pad 131 is arranged on the top of the rail support plate 2, and the under-board pad 132 is arranged on the rail support plate 2 bottom.

[0069] In the second embodiment of the present invention, the method of bonding the elastic pad 3 and the rail support plate 2 to form a bonded backing plate 13, combined...

Abstract

The invention discloses a track vibration attenuation fastener. The track vibration attenuation fastener comprises a positioning boss (4), an elastic cushion (3) and a locking mechanism; the elastic cushion (3) comprises two layers of cushion bodies, and a track bearing plate (2) is arranged between the two layers of cushion bodies; the locking mechanism comprises a locking nylon sleeve (6), a preassembled protrusion (61) and a preassembled groove (22) are mutually buckled, a flange (62) presses the top of the track bearing plate (2), and then the elastic cushion (3), the track bearing plate (2) and the locking nylon sleeve (6) form a preassembled structure; and the preassembled structure penetrates through a boss structure of the positioning boss (4) and is arranged on the top of a trackfoundation, the locking mechanism further comprises a locking cover plate (7) and a bolt assembly, and the locking cover plate (7) and the bolt assembly jointly compress the positioning boss (4) and the preassembled structure. The invention further discloses a track vibration attenuation fastener installing method. According to the track vibration attenuation fastener, preassembling of the elasticcushion, the track bearing plate and the locking nylon sleeve before delivery is effectively achieved, and quick installation on the site is achieved.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and more specifically relates to a rail vibration-damping fastener and an installation method. Background technique [0002] In recent years, the rapid development of the rail transit system has brought convenience to people's travel, but at the same time, the vibration and noise pollution brought by rail transit has also brought great troubles to people's production and life. [0003] Among many vibration reduction measures, fastener vibration reduction, as a vibration reduction measure with low cost, good vibration and noise reduction effect, and convenient installation and maintenance, has been widely used in a large number. Rail fastener products with vibration and noise reduction functions. Among the many vibration-damping fastener products, the detachable double-layer vibration-damping fastener realizes the vibration reduction of two layers of elastic body, has excellent vibration-dam...
