Description

Railway expansion joint fixing device {Rail Conclusion Structure of Expansion Joint Device joint System}

The present invention relates to an expansion joint system installed to cope with the expansion and contraction of rails in the longitudinal and lateral directions caused by temperature changes of railway rails. Expansion joint fixing device according to the present invention enables gauge adjustment between rails by gear-joining a push rod and an insulation block, controls hardening of the pad by forming a through hole in the anti-vibration pad, and according to another embodiment, the push rod and It includes a configuration in which the insulation block is integrally formed to reduce and prevent the loss of parts that often occur during the operation of the railway vehicle and strengthen the fastening force between the coil spring clip and the base plate.

In the railway environment in Korea where the temperature difference between the four seasons is extreme, the rail repeats the expansion and contraction movement according to the change in the temperature of the outside air in the longitudinal direction. If the stretching movement cannot be controlled, a buckling phenomenon in which the railway is twisted occurs, which is the biggest cause of railway derailment.

Accordingly, railway operators have installed expansion joint devices in the middle of the railway to cope with the displacement of the newly built rail.

1 and 2 show a front view of a conventional expansion joint device. That is, as shown in FIG. 1, the coil spring clip hanger 20, the lower part of which is embedded in the sleeper, is installed at a predetermined distance with the rail 10 in between, and the anti-vibration pad 30 is placed on the sleeper, and the base plate 40 is placed on the sleeper. ) is settled.

In addition, as shown in FIG. 2, a fixing groove 41 is formed on the base plate 40, and an insulating block 63 and a pusher 62 are sequentially inserted into the fixing groove 41.

The coil spring clip 70 mounted on the upper end of the coil spring clip hanger 20 and the clamp 62 applies a vertical force to the base plate 40, so that the rail 10 fixed to the base plate 40, the rail It is made up of a structure that allows the upper system of the expansion joint, including the brace 90, to be well fixed to the sleeper.

However, the expansion joint fixing device having the above configuration cannot simultaneously cope with rail transverse displacement and rail longitudinal displacement in which rail buckling occurs.

That is, when the rail 10 is displaced in the lateral or longitudinal direction due to a change in outside air temperature, the coil spring clip 70 is dismantled from the coil spring clip hanger 20 fixed to the sleeper using a tool or the rail brace It is necessary to adjust the position by loosening the bolt-type fixture fixing the 90 to the base plate 40, and to find and fix the gauge position that meets the standard again.

The adjustment operation takes a lot of labor and time, and since there are many unit parts necessary for adjustment, such as the coil spring clip 70, the clamp 62, and the insulation block 63, loss of parts may occur frequently during the operation.

The biggest problem is that railway vehicles cannot be operated during the adjustment work, so from the perspective of railway operators who have to operate according to the schedule, the increased opacity of the train operation plan exposes them to civil complaints from passengers and furthermore leads to a decrease in the competitiveness of railway transportation, leading to other problems. This leads to a situation in which passengers and cargo are taken away by competing means of transportation.

If the expansion joint system is a system in which a bolt-type fixture is used together with a coil spring clip, the operator must unscrew several screws fixing the base plate 40 and adjust the position of the expansion joint fixing device one by one according to the generated displacement. Accurate positioning will become more difficult and the above-mentioned problems of railway operators will become more serious.

Some try a method of responding to the change in the amount of expansion and contraction in the transverse and longitudinal directions of the rail by inserting a spacer piece prepared for each standard between the thumb 62 and the insulation block 63 of FIG. 2 . However, since at least 4 fixing devices used in the expansion joint system are used per sleeper, and at least 13 sleepers used in the one-place expansion joint system are used, it takes a lot of time to adjust them individually at intervals. There was a problem that more parts are required for the expansion joint system.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying FIGS. 3 to 6 .

1. First Embodiment

Hereinafter, an adhesive insulation rail system according to an embodiment of the present invention will be described with reference to FIGS. 3 to 6 .

The expansion joint system shown in FIG. 3 is a device that absorbs the displacement of rails that repeat expansion and contraction in the transverse and longitudinal directions of the track according to changes in the outside air, thereby preventing buckling and track deviations at a large level.

The rail 100 is fixed to the sleeper by the rail brace 900 instead of being fixed to the sleeper with a coil spring clip or a bolt-type fixture like a basic track.

At this time, a guide groove 920 is formed at the lower part of the rail brace 900, and the guide groove is combined with the protrusion 420 formed on the base plate 400 to slide, thereby responding to the displacement of the rail 100 in the longitudinal direction of the track. is configured so that

At one end of the rail brace 900, a second fixing part 910 on which the second fixture 1000 can be seated is formed. is formed so that the other end of the second coil spring clip 1100 having one end fastened to the second coil spring clip fixture 500 fixed to the base plate 400 can be stably fixed.

The second seating portion 1010 is installed to significantly reduce a phenomenon in which the second coil spring clip 1100 is detached from its original position due to an error in the track.

At this time, in order to easily adjust the longitudinal displacement according to the movement of the rail brace 900 according to the displacement due to the expansion and contraction of the rail in the longitudinal direction of the track, the lower end of the second fixture 1000 and the upper end of the second fixture 910 are gearedly coupled. can

That is, even if the second coil spring clip 1100 and the second fixture are not completely dismantled to adjust the track misalignment due to the longitudinal rail displacement, even if a measure of slightly relieving the fastening force is taken, the track misalignment due to the longitudinal displacement of the track can be adjusted. In addition, because it is geared, it is possible to easily adjust the track deviation for each set unit length (pitch).

At this time, the unit length can be adjusted by the gear pitch value, and as a result of examining the accuracy of general track misalignment repair work through research for the present invention, it was confirmed that it is optimal to set the value to 0.5mm to 2.0mm.

As a result of repeated tests on the ease of fastening and durability of the rail brace made of cast iron and the second fixture made of polyamide, it was confirmed that the angle of the screw thread was optimal between 60 and 80 degrees.

Figure 4 shows an exploded front view and cross-sectional view of the second fixture.

A first fixing part 410 on which the first fixture 600 can be seated is formed at an end of the base plate 400 .

The first fixture 600 is formed by gear-joining the first clamp 620 and the first insulating block 630 at the top.

The first coil spring fixture 200, to which one end of the first coil spring clip 700 is fixed, is installed at the end of the sleeper, and the other end is installed at the top of the first clamp of the first fixture 600. Seated in section 610.

The first seating portion 610 may be installed to significantly reduce a phenomenon in which the first coil spring clip is detached from its original position due to an error in the track.

The first coil spring clip 700 serves to fix the second coil spring coil fixture 500 and the base plate 400 on which the protrusions 420 are installed to the sleeper.

That is, even if the first coil spring clip 1100 and the first fixture 600 are not completely dismantled to adjust the track misalignment due to the transverse rail displacement, and only a slight relaxation of the fastening force is taken, the track due to the transverse displacement of the track In addition to being able to adjust the misalignment, it is gear-coupled so that the track misalignment can be easily adjusted for each set unit length.

At this time, the unit length can be adjusted by the gear pitch value, and as a result of examining the accuracy of general track misalignment repair work through research for the present invention, it was confirmed that it is optimal to set the value to 0.5mm to 2.0mm.

The angle of the screw thread was found to be 60 to 80 degrees optimal as a result of repeated tests on the ease of fastening and durability of the first clamp 620 made of cast iron (GCD450) and the first insulating block 630 made of polyamide (PA66). Confirmed.

That is, the first clamp 620 constituting the first fixture 600 and the first insulating block 630 are gearwise coupled to the position of the first fixture according to the transverse displacement of the rail of the expansion joint system according to the change in outdoor temperature can be easily adjusted, and the lower end of the second fixture 1000 and the upper end of the second fixture 910 are also gearwise coupled to the second fixture according to the displacement in the rail longitudinal direction of the expansion joint system according to the change in outside air temperature. By making it possible to easily adjust the position of the track, it is possible to precisely repair the misalignment of the track without dismantling the entire expansion joint fixing device.

At this time, between the first clamp 620 and the first insulating block 630 of the first fixture to supplement the track misalignment adjustment function in the lateral and longitudinal directions of the first fixture 600 and the second fixture 1000 It is possible to repair the transverse track misalignment of the track by inserting a 'L'-shaped first spacer adjusting piece and adjusting the thickness of each part of the first spacer adjusting piece.

Similarly, the second fixture 1000 is composed of a second clamp 1020 at the top and a second insulating block 1030 at the bottom, and a second spacing adjusting piece is inserted between the two components, and the second spacing adjusting piece By adjusting the thickness of each part, the track error in the longitudinal direction of the track can be repaired.

2. Second embodiment

Figure 5 shows a configuration in which the pusher of the first fixture and the insulation block configuration are integrated.

When the first fixture 600 and the second fixture 1000 are manufactured by being divided into a push bar and an insulation block, at least four fixtures used in a general expansion joint system are used per sleeper, and one expansion joint system Since the number of sleepers used is at least 13 or more, each number of parts is required to be at least 52, and since the expansion joint system is installed in multiple numbers across the line, too many parts are required.

The fixtures are divided into a push rod part and an insulation block part, so that the cast iron push rod handles the vertical compression force applied by the first and second coil spring clips without damage, and the insulation blocks buffer the impact force caused by the operation of the railroad car However, if there is a material with durability and elasticity, it can be manufactured and used as one part.

In the present invention, as a result of research to solve the above problems, the first fixture (600 ) was confirmed to have the same mechanical properties as when using the existing clamp and insulation block when manufactured and used integrally.

6 is a case where the first fixture 600 is used as an integral type as described above, as in the first embodiment, through the gear coupling between the first clamp 620 and the first insulating block 630, the track is wrong in the transverse direction of the track It shows a method of adjusting the lateral track deviation by adjusting the thickness of the lower end (X) of the integrated first fixture 600 instead of the method of adjusting the .

The thickness of the lower end (X) of the first fixture 600 is 4 mm at 4 mm intervals from 4 mm to 12 mm by reviewing the track misalignment repair contents for the expansion joint so far to increase the ease of track misrepair but limit the number of parts. It can be prepared in stages and the color of each part can be changed to make it easy to manage and store parts.

The thickness of the lower end (X) of the first fixture 600, the four-step values of the minimum length (L1) and the maximum length (L2) and classification for classifying each step are shown in Table 1 below.

In the present invention, the value of the first fixture 600 is divided into 4 stages, but the railroad operator can classify and manage the standard of the gripper differently according to the characteristics of the track to be operated.

As shown in Table 1, the reason why the name is set to the thickness of the lower end (X) of the first fixture 600 is because the thickness of the lower end (X) is a factor determining the actual lateral displacement.

name X L L1 color 4mm 4 52 41 black 6mm 6 54 43 Orange 8mm 8 56 45 White 10mm 10 58 47 Yeoncheong 12mm 12 60 49 green

In FIG. 5, the 'L'-shaped extension 650 installed below the first fixture 600 fills the space between the first coil spring clip fixture 200 and the base plate 400, and at the same time, the anti-vibration pad ( 300) shows a configuration that makes contact with the end.

The base plate 400 is a configuration that directly fixes the rail 100 and the rail brace 900 to the sleepers, and prevents the displacement of the expansion joint system due to the elongation of the track due to the change in outside air or the wheel of a high-speed railway vehicle. It is a configuration that is highly likely to generate displacement due to the generated impact force.

Therefore, in the present invention, a first seating portion 610 is formed on the upper end of the first fixture 600, on which one end of the first coil spring clip 700 is seated, and the base plate 400 is firmly fixed with a compressive force. At the same time, the lower extension part 650 of the first fixture 600 is brought into contact with the base plate 400 and the end of the elastic pad, so that the base plate 400 is easily separated according to the lateral displacement of the expansion joint system during operation. We propose a structure with a double structure that prevents

3. Third Embodiment

An anti-vibration pad 300 is positioned between the sleeper and the base plate 400 to absorb the impact force generated while the railway vehicle passes through the track, thereby preventing the fixing devices of the expansion joint system from being separated.

When the displacement burden is rapidly applied to the expansion joint due to the rapid expansion of the line during the change of season, heat wave, and winter season when the external temperature changes rapidly, the first coil spring clip 700 and the first fixture 500, which are fixing devices that fixed the rail 100 ), the second coil spring clip 1100, the second fixture 1000, the first spacing adjusting piece and the second spacing adjusting piece, etc., the fixing force is weakened. Accidents of being thrown out frequently occur.

The anti-vibration pad 300 is a very important part that plays an additional role of mitigating the accident and, on the other hand, improving the ride quality of passengers on the train.

Currently, it is known that more than 3 million anti-vibration pads 300 are installed only in the high-speed railway section, and it is expected that the number will increase further if the existing line section is added.

There is a report that the anti-vibration pad 300, which has an actual initial elastic modulus of 100 kN/mm, reaches 200 kN/mm, far exceeding the design standard tolerance of 120 kN/mm, within one year after installation, and its replacement demand is proportional to the frequency of railway operation. So it is growing exponentially.

In terms of maintenance cost, the replacement cost accounts for the largest portion of the maintenance cost of the expansion joint system.

The main reason why the anti-vibration pad 300 causes performance deterioration is that it is subjected to repeated impact forces of 160 or more times based on a formation of 20 cars even when one car passes due to the influence of at least four pairs of wheels installed per railway car, and it hardens shortly after installation It's that it doesn't do its job properly.

In addition, efforts to improve the speed of high-speed rail vehicles and railroad vehicles operating on existing lines, which railroad operators are steadily working on, are also cited as a factor that increases the impact force.

When the impact force is generated, a swelling phenomenon repeatedly occurs at the end of the anti-vibration pad 300 interposed between the sleeper and the base plate 400, thereby deteriorating the ability to absorb the impact force.

Therefore, in the present invention, several through holes 310 are formed on the end surface of the anti-vibration pad 300 to reduce the size of the swelling phenomenon at the end of the anti-vibration pad 300 .

In addition, the through hole 310 plays a role of minimizing the extent to which the area of the anti-vibration pad 300 increases or contracts according to a change in air temperature.

When a plurality of through-holes are installed as in the present embodiment, the amount of material used to manufacture the anti-vibration pad 300 is saved, and thus the manufacturing cost can be reduced, and thus the maintenance cost can be expected to be reduced.

The number and area of the through-holes 310 can be optimized and used by a railroad operator according to the number of times of operation of railroad vehicles, regional climate, and use environment.

The above description of the present invention is for illustrative purposes, and those skilled in the art can understand that it can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. will be. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined form.
