Description

Rail joint fastening device {APPARATUS FOR FASTENING JOINT MEMBER BETWEEN THE RAILS}

The present invention relates to a rail joint fastening device of a railway track, and more particularly, to a rail joint fastening device capable of preventing interference between components of a fastener and reducing vibration caused by the impact of a train.

In general, there is a certain limit to the length of the rail, so a seam is required at every predetermined distance, and the rail is normally joined every 20 to 25 m. The types of rail joints include general joints, insulated joints (general and adhesive insulation), and welded joints. The general joints are formed by connecting the rail joints with a gap (gap), and are in close contact with the insertion of insulating materials. Each insulated joint, which has room, is used to tie the two rails together using a joint plate.

Conventional general and insulated joint fastening device has a configuration as shown in Figs.

As shown in the figure, the steel plate 203 and the joint plate 203 and the rail 202, which are provided on both sides of the abdomen, to connect between the rails 202 mounted on the neck sleeper 201, An insulating resin fastening plate 204 made of a bolt and a nut to be penetrated perpendicularly to the running direction of the rail and between the joint plate 203 and the rail 202 to block electric flow between the rails on both sides. One side is inserted into both sides of the member 205 and the neck sleeper 201 is fixed by the clip hooks (206, 207) for fixing one end of the rail clip (coil spring clip) and the other end of the rail The rail clip 208 is pressed between the rail clip 208 and the upper surface of the bottom of the rail clip 208 and the rail 202 to press the lower portion to absorb the up and down movement of the rail due to the passage of the train, the rail clip 208 and the rail 202 Consists of an insulating piece 209 to prevent electrical connection of have.

On the other hand, in the fastening method of the rail joint, as shown in Fig. 3a, the position of the joint portion connecting the rails 101 is positioned directly above the sleeper 201 so that the sleeper directly bears the impact load of the train. As shown in Fig. 3B, there is a contact method, and a suspension method is provided in which the joint portion is placed between the sleeper 201 and the sleeper 201 '. Here, reference numeral 210 is an insulating material.

While the contact method is an example of the application of the configuration shown in FIG. 1 described above, it is effective for shock absorption and rail damage prevention of a train, while the insulation piece 209 and the rail clip 208 at the joint part are interfering with the joint plate. There is a problem of incomplete fastening.

That is, the rail 202 in the state in which the rail joint plate 203 is coupled is mounted on the sleepers 102 and 102 'and the rail clip 208 is inserted into the clip hanger 207 while the upper surface of the bottom of the rail 202 is inserted. To lock it. However, in this process, interference occurs between the lower portion of the joint plate 203 and the rail clip 208, and the joint plate 203 and the insulating piece 209 are not normally fastened. That is, since the rail clip 208 is spaced apart from the clip hanger 207 by the interference interval between the rail clip 208 and the joint plate 203, the interference part of the component when forcibly tightened by applying an excessive force without achieving a normal fastening Since it may be deformed or broken, it is fastened only to a degree of difficulty, and thus there is a problem in that the rail clip 208 does not function properly. In addition, since the rail 202 is installed on the neck sleeper 201, the rail bottom edge is severely damaged by the repeated train impact.

In addition, due to the interference between the joint plate 203 and the insulating piece 209, the insulating piece 209 wears or breaks, resulting in the bottom of the rail clip 209, the joint plate 203 and the rail 202. There is a problem that a large railroad accident due to a signal disturbance can be caused by the electrical connection by contact to constitute a track circuit of the railway electrical signal.

The suspension method is applied to the case where the seam can not be fastened by a method using a method of contact as shown in Figure 3b, but the length of the joint plate is longer than the sleeper reference interval as a fastening method for maintaining a normal sleeper interval. Due to the problem that the contact method is aggravated, the modified method of fastening the rail clip to the rail at the part out of the joint plate is adopted. However, in this manner, as shown in FIGS. 3A and 4, the joint is positioned between the sleeper 201 and the sleeper 201 ', and the center interval between the sleeper 201 and the sleeper 201' is greater than the length of the joint plate. It is set wide. Accordingly, the rail is severely sag during the train operation, and the phenomenon of stepping in the joint area due to the continuous impact of the train occurs. In other words, since both rail ends corresponding to the seam are formed in the form of inner beams, when the load of the train is applied to the rail ends, the rail 202 deflects by a predetermined amount of displacement δ. Accordingly, there are frequent cases of breakage of the joint plate 203 and the joint bolt 204 connecting the two rails 202, and the separation between the rails is feared.

In addition, when the train passes the stepped portion generated at the rail joint portion, abrasion and damage (end wear, end cracking, etc.) occur on the head of the rail due to impact and friction of the wheel, and cracks due to fatigue accumulation on the rail abdomen. If the crack is severe, there is a problem leading to breakage.

Accordingly, the present invention has been made in order to solve the above problems, the rail joints can be reliably achieved by fastening each rail independently of each other without interference between adjacent parts to fully demonstrate the unique function of each part The object is to provide a device.

In addition, the present invention adopts a dustproof pad and a rubber clip installed between the sleeper and the rail to simultaneously absorb the up and down vibration caused by the impact of the train, and can prevent the interference between the joint fastening parts to perform electrical insulation reliably. Another object is to provide a rail joint fastening device.

In addition, the present invention is to provide a rail joint fastening device that can achieve a complete fastening structure to prevent the track deformation to extend the life of the rail parts and ensure the economical safety and safety of train operation. have.
