Snap to fit before and after bush (3) Put the packing jaw (4a) from top to bottom to fit the dustproof fastening plate (2) packing jaw seat (2f), put the shiatsu washer (5) and the holding anchor (6) from top to bottom to cure on the concrete After tightening the nut (7) at a constant pressure, the left and right shocks generated during train operation are absorbed by the packing wing (4b), and the up and down shocks are absorbed by the packing jaw (4a) to reduce the impact and noise, and holding anchor (6) It is also manufactured to improve the durability of the rail pad seats (2e) of the anti-vibration fastening plate (2) by laying a rail pad (8) using rubber or polyurethane, which is an elastic body, the vertical impact of the rail pad (8) 1 It is a double dustproof structure that absorbs the car shock and passes it to the dustproof pad (1) through the dustproof fastening plate (2) to obtain the second dustproof effect. The thickness of the rail pad (8) and the dustproof pad (1) is adjusted to the upper and lower heights. Linear adjustment bush (3) a), Linear adjustment packing (4d) and linear adjustment shiatsu washer (5a) can be easily replaced by left and right linear adjustment.Replacement of the dustproof pad (1) only loosens the nut (7) and then tightens the antivibration fastening plate 20mm Tear off the edge of the dustproof pad (1) by lifting it to 30mm, and then replace it with a replacement dustproof pad (1a) that has also been torn the corner, and then glue the torn area with an adhesive. If you loosen the nut without removing the creep (9) from the rail, you can easily replace the dust pad (1) and the bush (3) packing (4). .

In Figure 3, the dust-proof fastening device for railway of the present invention is a dustproof pad (1) and a dustproof fastening plate (2) bush (3) packing (4) shiatsu washer (5) holding anchor (6) nut (7) rail pad (8) ) Is made of creep (9).

The anti-vibration pad (1) is made of elastic material such as rubber or polyurethane, laid on the bottom of the anti-vibration fastening plate (2), and the vertical load transmitted to the rails during the train operation is transmitted to the anti-vibration fastening plate (2), so that the anti-vibration pad is 1 mm vertically. Absorb vibration and repeat noise up to 2mm.

The anti-vibration fastening plate 2 is made of cast or high-strength plastic, the lower part of which is flat to attach the anti-vibration pad 1, and the rail pad 8 is laid in the center part and the rail pad seat 2e flat so that the rail can be settled. To mitigate the up and down impact of the rail side jaw (2c) and the bush and the packing insertion hole (2a), the creep insertion hole (2b), the creep surface (2d) and the dustproof plate (2) to prevent the rail left and right After inserting the packing jaw (2f), the packing jaw (4a) is pressed and the repulsive shock is absorbed after inserting the bush.The bush (3) has a large cross section to endure the lateral pressure by using a high-strength insulating material. Shoring Anchor (6) When the insertion hole rules are moved to the left and right, the linear adjustment bush (3a), the linear adjustment packing (4d), and the linear adjustment washer (5a) are moved to the left and right of the rail by ± 5 mm. Left and right shock and up and down half of the silver rail Made of rubber or polyurethane with moderate hardness to relieve force Packing jaw (4a) Packing wings (4b) Acupressure washers (4c) etc. ) Into the bush and the packing insertion hole (2a) to mitigate the up, down, left and right impact.

Put the pressure washer (5) on the top of the packing (4) and tighten the nut (7) from the top of the holding anchor (6). ) Serves to hold up, down, left and right shock relieving effect properly.

The holding anchor (6) uses a large holding anchor that is absolutely safe against corrosion and lateral pressure to compensate for the shortcomings of the existing small anchor, maximizing the bearing capacity and freeing up and down movements. This left and right shakes the safety operation, but the present invention, even if the nut is partially loosened, the holding anchor (6), bush (3), packing (4), etc., are embedded without gaps without any gaps, leading to accidents such as derailment. Was improved to a safe structure.

The nut 7 is a fastening material that presses the shiatsu washer 5 on the upper portion of the support anchor so that the entire dust-tightening device is integrated with the concrete or the sleeper, and the vertical motion is limited.

The rail pad 8 is made of polyurethane or rubber of low elasticity, and is applied to the rail and the dustproof fastening plate 2 so as to obtain a primary dustproof effect.

The creep (9) presses the rail and the anti-vibration fastening plate (2) at a constant spring pressure to hold the rails left and right and back and forth, and is a ready-made product.

As described above, the railway rail anti-vibration fastening device of the present invention, when the anti-vibration fastening plate 2 takes the large pillar anchor 6 as the guide pillar and descends when the dynamic load of the train is applied, and the dynamic load of the train disappears, the vibration pad 1 relies on restoring force. While moving up and down smoothly, the bush (3) and the packing (4) are used to raise and prevent the front and rear movement and the left and right movement and alleviate the up and down and left and right shocks. The maintenance cost was excessive due to frequent replacements due to cuttings, but the anti-vibration device used two large holding anchors to increase bearing capacity and durability.

The dust-tightening device uses a bush (3) and a packing (4) to move the left and right ± 5 mm simply by replacing the bushing (3a), packing (4d) shiatsu washer (5a) for linear adjustment while maintaining the insulation effect and elasticity. If it is necessary to replace the lower dustproof pad (1), loosen only the nut (7) of the upper part of the holding anchor (6), and fix the rail and the dustproof fastening device by 30mm upward positioning, and then use the knife to prevent the dustproof pad (1). After cutting to the left and right strut anchors (6), remove it, and cutting to the strut anchor (6) hole of the replacement dustproof pad. After inserting and fixing the cut part with adhesive or using the gap prevention material, the replacement is completed. Simple.

As mentioned above, the anti-vibration fastening plate 2 is a semi-permanent product by using casting or high-strength plastic and using a large holding anchor, and it is inexpensive to use the anti-vibration pad (1), bush (3), and packing (4). Since only the consumables are replaced and the end of life is depressed, the maintenance cost is more than 1/2 of the long-term use compared to the conventional products, and it is a railway dustproof fastening device that is absolutely safe for derailment.
