The present invention relates to an anti-vibration fastening device for railway rail joints, and more particularly, is disposed below the joints of railway rails and rails, and can absorb vibrations and noises generated from rail joints when the railroad vehicle travels or stops. It relates to a dustproof fastening device for railway rail joints.

In general, railway rail fasteners are used to secure railway rails to rail sleepers for railway vehicles.

As a conventional railway rail fastening device, a base plate welded to a metal plate such as steel or steel to a metal plate such as steel or steel is used. However, such a conventional base plate is close to the rail of the metal material and the vibration and noise during the running of the railway vehicle is very severe to damage the rail, sleepers and bogies, causing noise pollution around the railway and damage to the building. The fastening device for railway rails which has improved the conventional base plate is described in the design of Korean Utility Model Model No. 280105. In the design of the Korean Utility Model Utility Model No. 280105, a rail fixing plate having a shoulder on which rails are fastened so that the rails are fastened to the rail clips on both sides is coupled to the lower fixing frame fixed to the sleepers, and the lower fixing frames are both side walls. Two ends of the shoe extends to the sleeper fixing portion, and a shoe is formed adjacent to both ends of the fixing plate, and both ends of the rail fixing plate are inserted into the shoe to generate noise and vibration in the space between the rail fixing plate and the lower fixing frame. Disclosed is a vibration absorbing rail fixing assembly filled with a dustproof rubber layer. However, the Korean Utility Model Registration No. 280105 devised a dust-proof rubber layer only on the bottom of the rail fixing plate to directly contact the steel rail and the rail fixing plate, which is also steel, so that the noise was very high and the absorption of vibration was insignificant.

Applicant developed the anti-vibration fastening device for railway rails to improve the shortcomings of the devised Korean Utility Model No. 280105, was registered as Korea Utility Model No. 235976, and received the result of the technical evaluation. The anti-vibration fastening device for railway rails according to the invention of Korean Utility Model No. 235976 is installed on an upper surface of a rail sleeper, and has a base member having an upper and a lower portion opened at a predetermined width in the center of the main body; It is formed of an elastic material, the inside is formed with an insertion groove formed through the longitudinal direction, the buffer member is integrally attached to the base member; Clip support to which the pendroll clip for supporting and fixing the lower part of the rail is coupled is formed at both sides with a predetermined interval for seating the rail, and the sound absorbing induction hole to which the buffer member is coupled is drilled. It is composed of a clip connecting member is mounted to be located at a predetermined thickness on the upper surface. The Korean Utility Model Registration No. 235976 devises a buffer member on the upper and lower surfaces of the clip connection member and connects the buffer member to each other by a buffer member filled in the sound-absorbing induction hole so that the rail contacts the buffer member. At the same time, the vibration and noise generated by the shock absorbing member in contact with the rail are transmitted to the shock absorbing member of the lower surface of the clip connecting member through the sound absorbing guide hole so as to disappear. Although the design of Korean Utility Model No. 235976 is very innovative to remove the vibration and noise of railway rails, it cannot be used on the rail and the lower part of the rail where the noise and vibration are most generated and the load on the fastening device is the highest. There are disadvantages. That is, the sound absorbing induction hole formed in the clip connecting member is located at the point connecting the center of the clip support, and the cushioning member is filled in the sound absorbing inducing hole, so that the clip connecting member is deformed without enduring the shock generated in the rail joint. There is a disadvantage of being damaged.

The present invention has been made to solve the above-mentioned problems of the prior art, and to provide a dust-proof fastening device for railroad rail joints that can absorb vibration and noise while withstanding the shock generated in the joint of the railroad rail.

Anti-vibration fastening device for railway rail joint according to the present invention to achieve the above object
