Problems solved by technology

The main disadvantage of the overall vulcanized shear type damping fastener is that the stiffness cannot be adjusted, and the vulcanized rubber layer is easy to peel off. Once the vulcanized rubber layer is damaged, the entire fastener needs to be replac

Embodiment Construction

[0019] The present invention will be described in further detail below according to the drawings and embodiments.

[0020] refer to Figure 1-Figure 6 , the present invention, the side-lock type double-layer damping fastener, including anchor bolt 1, heavy spring washer 2, flat spacer 3, nylon insulation cover 4, upper iron backing plate 5, middle elastic backing 6, lower iron backing plate 7. Insulation cushion plate 8, base 9, nylon sleeve 10, insulation gauge block 11, steel rail 12, elastic bar 13.

[0021] The structure of the fastener is as follows: a nylon sleeve 10 is pre-embedded in the base 9, an insulating cushion plate 8 is directly laid on the base 9, and the lower iron plate 7 and the middle elastic pad are successively laid on the insulating cushion plate 8. Layer 6 and the upper iron backing plate 5, there are two protruding columns 71 on the lower iron backing plate 7, and there is a through hole in the middle of the column 71, the through hole and the bolt h...

Abstract

The invention discloses a laterally locking type double-layer vibration damping fastener, comprising an anchor bolt, a heavy-duty spring washer, a flat cushion block, a nylon insulated cover, an upper-layer iron plate, a middle elastic cushion layer, a lower-layer iron plate, an insulated buffer plate, a substrate, a nylon sleeve, an insulated track gauge block, a steel rail and an elastic bar. The laterally locking type double-layer vibration damping fastener has the benefits that a laterally locking structure in innovation design is adopted, the fastener can be manually dismounted without using a special tool, maintenance and replacement of the middle elastic cushion layer are simple, and maintenance is convenient.

Description

technical field [0001] The invention relates to a double-layer vibration-damping fastener, in particular to a side-lock type double-layer vibration-damping fastener. Background technique [0002] With the large-scale development of urban rail transit, the resulting vibration and noise problems have become more and more prominent. If no effective measures are taken, it will not only reduce the comfort of passengers, but also reduce the service life of various parts of the vehicle, and will also affect the railway. The quality of work and life of residents along the line and the life span of various equipment and buildings. Therefore, controlling and reducing the vibration and noise caused by the subway has become one of the important topics in the development of urban rail transit. [0003] The fastener system, as a component that fixes the rail on the track bed and enables the rail to move vertically, horizontally and longitudinally, plays a major role in the vibration redu...
