Description

Technical Field

[0001] This utility model belongs to the field of track vibration reduction support technology, and in particular relates to a vibration reduction support device for tracks. Background Technology

[0002] Track support devices are key components used to stabilize and protect the track structure. A typical track support device includes a rail, a base plate, a connector, a first support member, and a second support member. One end of the connector is connected to the rail, and the other end is connected to the base plate. The first and second support members are mounted on the base plate and are respectively located on both sides of the connector.

[0003] Traditional track installation typically involves directly fixing the track to the sleepers using bolts or clamps. This method results in poor vibration damping when trains pass, leading to strong vibrations and significant noise. The resulting vibrations and noise can have an impact on the surrounding environment. Furthermore, the poor vibration damping reduces the track's lifespan, and prolonged severe vibrations can easily cause the track to break. To address the issue of track vibration damping, we propose a vibration damping support device for tracks. Utility Model Content

[0004] The purpose of this invention is to provide a vibration damping support device for railway tracks. Specifically, after the support base and the I-shaped track are installed, two U-shaped elastic shafts are inserted into the I-shaped track. When the I-shaped track is compressed by a train, the track presses the lower U-shaped elastic shafts downwards, thus providing a first-stage buffer. Simultaneously, it presses down the damper and buffer spring, providing a second-stage buffer. This effectively reduces vibration and noise. The significant vibration reduction also extends the track's service life. This invention solves the problem of traditional track installation methods that directly fix the track to the sleepers using bolts or clamps. This method results in poor vibration damping when trains pass, leading to strong vibrations and significant noise. The resulting vibrations and noise have an impact on the surrounding environment, and the poor vibration damping reduces the track's service life.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a vibration damping support device for rail tracks, comprising several sleepers. An I-shaped rail is provided on the front and right sides of the top of each sleeper. Vibration damping support components are provided on the front and back of each I-shaped rail. Each vibration damping support component includes a support base. Two fixing blocks are fixedly connected to the bottom outer side of the support base. Two U-shaped elastic shafts are fixedly connected inside each of the two fixing blocks. Four openings are provided inside the support base, and the U-shaped elastic shafts are disposed inside the openings. Two of the U-shaped elastic shafts are inserted into the I-shaped rail.

[0007] Furthermore, the side surface of the U-shaped elastic shaft away from the fixed block contacts the outer surface of the I-shaped track, two positioning blocks are fixedly connected to the bottom of the support base, and two insertion holes are opened on the bottom outer side of the support base.

[0008] Furthermore, the positioning block contacts the sleeper surface on the side closest to the sleeper, the bottom of the support base contacts the top of the sleeper, and the top of the support base extends to the inner side of the I-shaped track on the side closest to the I-shaped track. Several anti-deviation blocks are fixedly connected to the inner wall of the I-shaped track. The several anti-deviation blocks are arranged in groups of two, and each group of two anti-deviation blocks is inserted into the support base.

[0009] Furthermore, a threaded shaft is provided inside the insertion hole, the bottom of the threaded shaft is fixedly connected to the top of the sleeper, and a nut is threadedly connected to the outer surface of the threaded shaft.

[0010] Furthermore, two placement holes are provided on the top of the sleeper, and a damper is installed inside the placement hole. A buffer spring is sleeved on the outside of the damper. A convex circle is fixedly connected to the top and bottom of the damper. The top of the upper convex circle contacts the bottom of the I-shaped track, and the bottom of the lower convex circle is fixedly connected to the bottom of the inner wall of the placement hole.

[0011] Furthermore, the top of the buffer spring is fixedly connected to the bottom of the upper convex circle, the bottom of the buffer spring is fixedly connected to the top of the lower convex circle, and the side of the support seat near the I-shaped track is in contact with the surface of the I-shaped track.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting up a support and vibration damping component, specifically, after the support base and the I-shaped track are installed, two U-shaped elastic shafts are inserted into the I-shaped track. When the I-shaped track is squeezed by the train, the I-shaped track will press the U-shaped elastic shafts below downward, thus playing a first buffering role. At the same time, it will press the damper and the buffer spring together, thus playing a second buffering role. This effectively and significantly reduces vibration and noise generation. The significant vibration reduction of the I-shaped track also increases its service life.

[0014] 2. This utility model incorporates anti-deviation blocks. Specifically, during installation, the support base is inserted into two anti-deviation blocks within the I-shaped track. These anti-deviation blocks serve to limit and position the track, preventing it from shifting and improving safety. They also prevent large vibrations from causing displacement of the I-shaped track. Furthermore, the anti-deviation blocks enhance the rigidity of the I-shaped track.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-5 As shown, this utility model is a vibration damping support device for rails, including several sleepers 1. I-shaped rails 11 are provided on the front and right sides of the top of each sleeper 1. Vibration damping support components 12 are provided on the front and back of each I-shaped rail 11. Each vibration damping support component 12 includes a support base 121. Two fixing blocks 122 are fixedly connected to the bottom outer side of the support base 121. Two U-shaped elastic shafts 123 are fixedly connected inside each of the two fixing blocks 122. Four openings 124 are provided inside the support base 121, and the U-shaped elastic shafts 123 are disposed inside the openings 124. The two U-shaped elastic shafts 123 are connected to the I-shaped rails. The I-shaped track 11 is inserted, and a support and vibration damping component 12 is set up. Specifically, after the support base 121 and the I-shaped track 11 are installed, two U-shaped elastic shafts 123 are inserted into the I-shaped track 11. When the I-shaped track 11 is squeezed by the train, the I-shaped track 11 presses the U-shaped elastic shafts 123 below downward, thus playing a first buffering role. At the same time, it presses the damper 141 and the buffer spring 142 together, thus playing a second buffering role. This effectively reduces vibration and noise. The significant vibration reduction of the I-shaped track 11 also increases its service life.

[0026] The side surface of the U-shaped elastic shaft 123 away from the fixed block 122 contacts the outer surface of the I-shaped track 11. Two positioning blocks 125 are fixedly connected to the bottom of the support base 121. Two insertion holes 126 are opened on the bottom outer side of the support base 121. When the support base 121 is installed, the positioning blocks 125 at the bottom will be inserted into the two sleepers 1 to play a positioning role, making the support base 121 more stable after installation.

[0027] The positioning block 125 contacts the surface of the sleeper 1 on the side closest to the sleeper 1, and the bottom of the support base 121 contacts the top of the sleeper 1. The top of the support base 121 extends to the inner side of the I-shaped track 11 on the side closest to the I-shaped track 11. Several anti-deviation blocks 111 are fixedly connected to the inner wall of the I-shaped track 11. The anti-deviation blocks 111 are set in pairs, and the two anti-deviation blocks 111 in each pair are inserted into the support base 121. By setting the anti-deviation blocks 111, specifically, when the support base 121 is installed, it is inserted into two anti-deviation blocks 111 inside the I-shaped track 11. The anti-deviation blocks 111 are used to limit and position, so that the I-shaped track 11 will not deviate, thus improving safety performance. At the same time, it avoids the problem of displacement of the I-shaped track 11 due to large vibrations. At the same time, the setting of the anti-deviation blocks 111 can improve the rigidity of the I-shaped track 11.

[0028] The insertion hole 126 is provided with a threaded shaft 13. The bottom of the threaded shaft 13 is fixedly connected to the top of the sleeper 1. The outer surface of the threaded shaft 13 is threaded with a nut 131. When the support base 121 is installed, it is inserted into the threaded shaft 13 through the insertion hole 126. Then, the nut 131 is installed on the threaded shaft 13, and the support base 121 is fixed and the installation is completed.

[0029] Two placement holes 14 are provided on the top of the sleeper 1. A damper 141 is installed inside the placement hole 14. A buffer spring 142 is sleeved on the outside of the damper 141. A convex circle is fixedly connected to the top and bottom of the damper 141. The top of the upper convex circle contacts the bottom of the I-shaped track 11, and the bottom of the lower convex circle is fixedly connected to the bottom of the inner wall of the placement hole 14. The upper convex circle can increase the contact area with the I-shaped track 11, thereby improving stability.

[0030] The top of the buffer spring 142 is fixedly connected to the bottom of the upper convex circle, and the bottom of the buffer spring 142 is fixedly connected to the top of the lower convex circle. The side of the support base 121 near the I-shaped track 11 is in contact with the surface of the I-shaped track 11. The upper convex circle and the lower convex circle cooperate to better compress the buffer spring 142.

[0031] One specific application of this embodiment is:

[0032] In use, the support base 121 is installed on both sides of the I-shaped track 11. During installation, the support base 121 is inserted into the two anti-deviation blocks 111 inside the I-shaped track 11 to limit and position the track, preventing deviation and improving safety. This also avoids displacement of the I-shaped track 11 due to significant vibration. When installing the I-shaped track 11, the two U-shaped elastic shafts 123 are inserted into the I-shaped track 11, providing support. The bottom of the I-shaped track 11 contacts the top of the damper 141. Simultaneously, the positioning block 125 at the bottom of the support base 121 is inserted into the two sleepers 1 and into the threaded shaft 13 through the insertion hole 126. Then, the nut 131 is installed on the threaded shaft 13, thus securing the support base 121. 21 is fixed to facilitate the installation of the support base 121. When the I-shaped track 11 is squeezed by the train, the I-shaped track 11 will press the U-shaped elastic shaft 123 below downward, thus playing a first buffering role. At the same time, the bottom of the I-shaped track 11 will press the damper 141 downward, and the buffer spring 142 will be pressed together, thus playing a second buffering role. The damper 141 at the same time avoids rapid rebound, thus effectively playing a significant vibration reduction role and reducing noise generation. The significant vibration reduction of the I-shaped track 11 also improves its service life. Finally, when the train passes, the I-shaped track 11 will slowly return to its original position through the action of the damper 141, and the U-shaped elastic shaft 123 above will play a limiting and anti-rebound role, keeping the position of the I-shaped track 11 at the limit and preventing excessive rebound.
