Description

Concluding implements for insulated connector of track}

The present invention relates to a track joint insulation fastening device according to the present method, and more specifically, in a long or a precision rail that is not a long rail or an adhesive rail in which the joint is integrally formed, the joint of the rail is formed between the sleeper and the sleeper. The present invention relates to a track joint insulation fastening device which is applied.

In general, a rail is joined to several precision rails and a rail installed more than 200m without a joint is called a long rail or an adhesive rail, and the rails below are represented by a long rail and a precision rail.

The rails are configured to enable electricity to send electrical signals, but pass through the insulation section by sending current from the rails to the conducting lines in places such as stations, crosswalks, and branches, which are sections that need to be insulated as necessary. It is then bonded again to send current to the rails.

Due to this characteristic, the rail is equipped with a seam insulation fastening device configured to short-circuit the seam.

In the case of the above-mentioned long rail, the elastic insulating material is inserted into the joint and fixed with an insulating joint plate made of synthetic resin, thereby eliminating the insulation effect of the joint and the gap of the joint, thereby causing the rattling during driving and the accumulation of the impact. To reduce the damage to the track.

However, in the section of the general long rail or the precision rail section, the gap between the rails is set to several tens of millimeters in consideration of the expansion and contraction of the rail due to temperature. It consists only of a device that is combined with existing ones.

4 and 5 are perspective views showing an orbital joint insulation fastening device currently used.

In the case of FIG. 4, the insulating joint plate 3 is mounted at both sides between the rails 2 and is coupled using a fastener 4 composed of several bolts and nuts.

However, in the above case, the shape of the commonly used coil spring 5, which is mounted to couple the sleeper 1 and the rail 2 to suppress vertical vibration, is formed in a shape in which one side is bent upwards. In the part joined by 3), the coupling is difficult due to the thickness of the insulating joint plate 3 and the bent portion of the fastener 4.

Therefore, the coil spring 5 was coupled by extending the gap L1 between the sleepers 1 to a portion where the insulation joint plate 3 was not joined.

The configuration as described above is configured to increase the interval between the sleepers in the joint portion where the impact is most accumulated during the running of the train, there is a risk of breakage and the hassle of frequent track repair.

Figure 5 is another embodiment of the prior art, and is bonded without extending the interval (L2) between the sleepers (1) This configuration of the coil spring (5) is partially or impossible to fasten the base plate (6) The side of the rail 2 is pushed by the coil spring hanger 61 formed on the upper surface.

However, the above configuration is to suppress the lateral vibration by the coil spring hanger 61, but lack of means for suppressing and dispersing the up and down vibration, the deviation of the phase due to the fatigue accumulation of the joint of one of the weak line part, By bringing about wear and vertical track settling, this also increases the risk of accidents and the need for frequent track maintenance.

In addition, in the embodiment of FIGS. 4 and 5, the interval fixed by the coil spring 5 becomes longer, and the rail 2 extends in the driving direction when the rail 2 is extended by thermal expansion when the temperature is high, such as in a hot summer. It is easy to occur when both ends are touched by the force of, and as a result, electricity is increased, which increases the possibility of a large accident due to malfunction of the electric signal.

Therefore, there is an urgent need for the development of a track joint insulation fastening device that facilitates the coupling of coil springs that maintains safety intervals between sleepers and suppresses and distributes vertical vibration of tracks.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is a joint joint formed in the joint between the sleeper in the normal or long rail section insulated joint in the section of fastening the track joint insulation fastening device It is to provide a means that can easily absorb the vibration in the vertical direction and even in the place where the plate is installed.

The present invention also provides a rigid track joint insulation fastening device which prevents the rails from contacting each other and degrades the insulation effect while the gap between the joints changes according to the expansion of the rail or the force in the train driving direction due to the temperature.

In addition, between the bottom surface of the rail 2 and the upper surface of the base plate 6, rubber pads 7 having guide jaws 71 formed at both ends thereof are mounted to provide a cushioning effect of increasing the insulation effect and vertical vibration.

In addition, in order to further secure the fastening of the joint portion, the fasteners 4 form the auxiliary plates 43 on both sides in addition to the bolts 41 and the nuts 42 to be firmly coupled to each other, and prevent the electric current from being supplied to the auxiliary plates 43.
