Description

Technical Field

[0001] This application relates to the field of railway track technology, and in particular to a railway track fastener anti-loosening mechanism. Background Technology

[0002] Railway tracks, also known as rails, are mainly used on railways and work in conjunction with switches to allow trains to travel without turning. Railway tracks typically consist of two parallel steel rails fixed on sleepers, with ballast underneath. Railway tracks, made of steel, can withstand greater weight than other materials. Sleepers, also called rail sleepers, are used to distribute the weight and pressure on the rails and to maintain a fixed track gauge.

[0003] However, the existing railway track fastener anti-loosening mechanism is traditionally fixed by bolts. However, the contact area of ​​bolts is small, and the vibration of the track will affect the stability of the bolt installation. Therefore, it is necessary to increase the contact area between the bolt and the track during installation, and at the same time, it is necessary to mitigate the vibration to avoid the vibration affecting the stability. Utility Model Content

[0004] In view of the above problems, this application provides a railway track fastener anti-loosening mechanism to solve the problem that the existing railway track fastener anti-loosening mechanism is traditionally fixed by bolts. However, the contact area of ​​the bolts is small, and the vibration of the track will affect the stability of the bolt installation. Therefore, it is necessary to increase the contact area between the bolt and the track during installation, and at the same time, it is necessary to mitigate the vibration to avoid the vibration affecting stability.

[0005] This application provides a railway track fastener anti-loosening mechanism. It includes: a sleeper, a pad fixedly installed at the top of the sleeper, a rotating rod movably sleeved on one side of the pad, a first bevel gear fixedly installed on one side of the rotating rod, a second bevel gear meshing with the surface of the first bevel gear, screws fixedly installed on one side of the two second bevel gears, threaded blocks threadedly connected to the surfaces of the two screws, a clamping plate fixedly installed at the top of the threaded blocks, and a track body installed at the top of the pad.

[0006] With the above scheme, after the track body is installed on the pad, the first bevel gear is rotated by turning the rotating rod. The first bevel gear meshes with the second bevel gear and rotates the screw, causing the threaded block to move on the screw surface. This causes the clamping plate to move and limit the movement of the track body on both sides.

[0007] In some embodiments, the top of the pad is symmetrically provided with limiting grooves, and the two threaded blocks are movably sleeved inside the limiting grooves.

[0008] With the above scheme, when the threaded block moves threadedly on the screw surface, it also slides in the limiting groove, which limits the rotation of the threaded block and provides adjustment space for the track body.

[0009] In some embodiments, the inner walls of the two clamps are provided in a groove shape.

[0010] With the above solution, since the inner wall of the clamping plate is grooved, it can better fit the outer wall of the track body when limiting and clamping the track body.

[0011] In some embodiments, a bidirectional lead screw is movably sleeved on one side of the two clamping plates, and a limit block is symmetrically threaded on the surface of the two bidirectional lead screws. A support rod is hinged to the top of the two limit blocks, and the top of the two support rods is hinged to the bottom of the limit plate.

[0012] With the above scheme, after the track body is installed on the pad, the two-way screw is turned, causing the two limiting blocks to move threadedly on the surface of the two-way screw, thereby pushing the support rod to unfold. Then, the limiting plate is pushed, causing the limiting plate to slide out of the receiving groove and limit and clamp the track body. The limiting plate increases the contact area during clamping.

[0013] In some embodiments, the inner walls of the two clamping plates are provided with storage grooves, and the limiting plate is movably sleeved inside the storage grooves.

[0014] The above solution allows for the storage of the limiting plate via a storage slot, preventing it from interfering with the installation of the main track.

[0015] In some embodiments, sliders are symmetrically installed on both sides of the two limiting blocks, and four sliders are movably sleeved inside the slide grooves, with the two slide grooves symmetrically opened on the inner wall of the storage groove.

[0016] With the above scheme, when the limiting block moves threadedly on the surface of the bidirectional lead screw, the slider also slides in the groove, and the slider and groove play a good limiting role.

[0017] In some embodiments, rubber blocks are fixedly installed on both clamping plates and limiting plates equally.

[0018] The above solution utilizes the flexibility of the rubber blocks to ensure a closer fit between the clamping plates and limiting plates when they clamp the main body of the track, increasing the contact area. The flexibility of the rubber blocks also provides a certain buffering effect, reducing the impact of vibration.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By turning the rotating rod, the first bevel gear is driven to rotate, and the first bevel gear meshes with the second bevel gear to rotate, which in turn drives the screw to rotate, causing the threaded block to move on the screw surface, thereby driving the clamping plate to move. The clamping plates on both sides limit and clamp the two sides of the track body, so that the two sides can better contact the two sides of the track body, increasing the stability and firmness of the limit installation.

[0021] 2. By turning the double-acting screw, the two limiting blocks move threadedly on the surface of the double-acting screw, thereby pushing the support rod to unfold. This pushes the limiting plate, causing it to slide out of the receiving groove and clamp the track body. The limiting plate increases the contact area during clamping. The flexibility of the rubber block allows the clamping plate and limiting plate to fit more closely to the track body, increasing the contact area. The flexibility of the rubber block also provides a certain buffering effect, reducing vibration force.

[0022] The above description is merely an overview of the technical solutions of the embodiments of this application. In order to better understand the technical means of the embodiments of this application and to implement them in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the embodiments of this application more obvious and understandable, specific implementation methods of this application are described below.

[0034] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0035] This application provides a railway track fastener anti-loosening mechanism. For example... Figures 1-4 As shown, it includes: a sleeper 1, a pad 2 fixedly installed on the top of the sleeper 1, a rotating rod 3 movably sleeved on one side of the pad 2, a first bevel gear 4 fixedly installed on one side of the rotating rod 3, a second bevel gear 5 meshing with the surface of the first bevel gear 4, a screw 6 fixedly installed on one side of the two second bevel gears 5, a threaded block 7 threadedly connected to the surface of the two screws 6, a clamping plate 8 fixedly installed on the top of the threaded block 7, and a track body 10 installed on the top of the pad 2.

[0036] After the track body 10 is installed on the pad 2, the first bevel gear 4 is rotated by turning the rotating rod 3. The first bevel gear 4 meshes with the second bevel gear 5 and rotates the screw 6. This causes the threaded block 7 to move threadedly on the surface of the screw 6, thereby moving the clamping plate 8. The clamping plates 8 on both sides limit and clamp the track body 10 on both sides.

[0037] In the technical solution of this application embodiment, the top of the pad 2 is symmetrically provided with limiting grooves 9, and two threaded blocks 7 are movably sleeved inside the limiting grooves 9.

[0038] When the threaded block 7 moves threadedly on the surface of the screw 6, it also slides in the limiting groove 9, which limits the rotation of the threaded block 7 and provides adjustment space for the track body 10 during placement.

[0039] In the technical solution of this application embodiment, the inner walls of the two clamping plates 8 are provided in a groove shape.

[0040] Because the inner wall of the clamping plate 8 is grooved, it can better fit the outer wall of the track body 10 when limiting and clamping it.

[0041] In the technical solution of this application embodiment, two bidirectional lead screws 11 are movably sleeved on one side of the two clamping plates 8. Limiting blocks 12 are symmetrically threaded on the surfaces of the two bidirectional lead screws 11. Support rods 13 are hinged to the top of the two limiting blocks 12. The top of the two support rods 13 are hinged to the bottom of the limiting plate 14.

[0042] After the track body 10 is installed on the pad 2, the double-acting screw 11 is turned so that the two limiting blocks 12 move threadedly on the surface of the double-acting screw 11, thereby pushing the support rod 13 to unfold. The limiting plate 14 is then pushed so that the limiting plate 14 slides out of the receiving groove 15 to limit and clamp the track body 10. The limiting plate 14 increases the contact area during clamping.

[0043] In the technical solution of this application embodiment, the inner walls of the two clamping plates 8 are provided with storage grooves 15, and the limiting plate 14 is movably sleeved inside the storage grooves 15.

[0044] The limiting plate 14 can be stored in the storage slot 15 to prevent the limiting plate 14 from affecting the installation of the track body 10.

[0045] In the technical solution of this application embodiment, two limit blocks 12 are symmetrically installed with sliders 16 on both sides, four sliders 16 are movably sleeved inside the slide groove 17, and two slide grooves 17 are symmetrically opened on the inner wall of the storage groove 15.

[0046] When the limiting block 12 moves threadedly on the surface of the bidirectional lead screw 11, the slider 16 also slides in the groove 17, and the slider 16 and the groove 17 play a good limiting role.

[0047] In the technical solution of this application embodiment, rubber blocks 18 are fixedly installed on both clamping plates 8 and limiting plate 14 equally.

[0048] Due to the flexibility of the rubber block 18, when the clamping plate 8 and the limiting plate 14 limit and hold the track body 10, they can fit more closely, increasing the contact area. The flexibility of the rubber block 18 also plays a certain role in buffering and reducing the vibration force.

[0049] Working principle: After the track body 10 is installed on the pad 2, turning the rotating rod 3 drives the first bevel gear 4 to rotate, which in turn drives the second bevel gear 5 to rotate, which in turn drives the screw 6 to rotate, causing the threaded block 7 to move threadedly on the surface of the screw 6, thereby moving the clamping plate 8. The clamping plates 8 on both sides limit and clamp the track body 10. Turning the double-acting screw 11 causes the two limiting blocks 12 to move threadedly on the surface of the double-acting screw 11, thereby pushing the support rod 13 to unfold, pushing the limiting plate 14, causing the limiting plate 14 to slide out from the receiving groove 15, and limiting and clamping the track body 10. The limiting plate 14 increases the contact area during clamping. The flexibility of the rubber block 18 allows the clamping plate 8 and the limiting plate 14 to fit more closely when limiting and clamping the track body 10, increasing the contact area. The flexibility of the rubber block 18 also plays a certain role in buffering and reducing the vibration force.

For example, in the claims, any of the claimed embodiments can be used in any combination.
