Description

Roller base plate for railroad turnouts

The present invention relates to a roller base plate for a railroad diverter, and in particular, a railroad that smoothly converts by reducing frictional force between the rail and the roller due to the linear contact between the roller and the tongue due to the rolling motion of the roller during the rolling of the tongue. It relates to a roller base plate for a turner.

In general, a turnout is a facility on a track installed to move a train or vehicle from one track to another on a railroad, in which a pair of rails gradually opens when a pair of rails are separated into two pairs of rails. It is fixed, and two tongrails are installed therebetween, and a train for operating the tongrail is installed, so that the train can operate the pair of rails selectively.

In other words, when operating the transfer machine, the two tongrails installed in the center of the tapping machine move at the same time to be in contact with the base rail of any one of the two fixed rails and spaced apart from the other base rail.

Here, two tong rails and two rails installed in the middle and the lower side of the base rail is installed at equal intervals, the base plate is fixed at one side of the base plate is fixed to one side of the base plate, the tongue rail is placed on the slide surface The tongue rail is selectively moved to both basic rails while being rubbed against the slide surface by a train.

Here, the conventional base plate, as described above, is made of metal, and the support and the slide surface are integrally formed, and the friction force between the tongue rail and the slide surface is greatly increased when the tungsten rail placed on the slide surface is selectively moved to both basic rails by a train. Due to the action, the movement is not smooth, and in order to smooth the movement by reducing the friction between them to periodically apply the waste oil or lubricating oil to the slide surface of the base plate.

However, as described above, when applying waste oil or lubricating oil to the slide surface of the base plate, not only a lot of manpower needs to be put into operation but also a human accident may occur due to the operation of the train. Not only does it invade the groundwater and soil, but also has a problem in that the surrounding environment is very poor.

In addition, if waste oil or lubricating oil is not applied to the slide surface of the base plate as described above, the slide surface is oxidized by rainwater, and even though the rail is not properly moved, the rail rail does not move properly, which causes a problem in train progress. Cases tend to occur.

Therefore, in order to solve the conventional problems as described above, the auxiliary base plate of the utility model registration application No. 2000-0006264 railway diverter has been proposed.

The auxiliary base plate of the conventional railway turnout as described above forms a support between the narrow end and the rear end formed of the fixing piece and the locking jaw at the front end of the frame, and forms a long hole in the frame to keep the front end of the roller house as the hinge axis. And to install the height adjustment bolt on the rear end of the pipe to move between the configured to adjust the height of the roller house; The teeth are formed between the movements of the height adjustment bolts inserted into the fixed bolts between the adjustments, and the teeth of the frames and the movements of the heights are adjusted so that the front and rear positions of the roller house can be adjusted. The auxiliary base plate of the railway diverter characterized in that the thread groove is formed by screwing the height adjusting screw and the fixing screw into the screw groove, and sandwiching the shaft of the roller between them, and installing a bearing between the roller and the shaft. " It can be seen that it is a feature.

Auxiliary base plate of the conventional railway splitter made of the configuration as described above can be easily used by installing between the sleepers, there is an advantage that the position adjustment and height adjustment is possible.

However, the auxiliary base plate of the conventional railway splitter as described above can be used only for the neck sleepers, there is a problem that can not be used for PC sleepers, and also can be gravel work by installing in the center of the sleepers. It is structurally weak in strength, so it is located in the sleeper section when it is used in the neck sleeper section with high up and down vibration.Therefore, there is a risk of breakage due to bending because the vertical load cannot be received from the sleeper.

Therefore, the present invention has been devised to solve the problems described above, by reducing the friction force acting between the tongue rail and the roller due to the linear contact between the roller and the tongue by rolling motion by the roller during the conversion of the tongue. It is an object of the present invention to provide a roller base plate for a railway turnout that facilitates the conversion.
