Technical Field

[0001] The utility model relates to the technical field of railway track fastening, in particular to a railway track fastening clip for preventing track fracture. Background Art

[0002] Railway tracks, also known as road tracks, railway tracks, tracks, etc., are mainly used on railways and cooperate with switches to enable trains to run without turning.

[0003] Railway tracks usually consist of two parallel steel rails. The steel rails are fixed on sleepers, and road ballast is placed under the sleepers. They are fastened by railway accessories such as rail braces, fasteners, rail clamps, rail splices, elastic clips, and railway spikes.

[0004] Railway tracks are made of steel and can bear greater weight than other materials. Sleepers, also known as crossties, concrete sleepers, or road sleepers, function to distribute the weight of the steel rails and the pressure exerted on the steel rails, and to maintain a fixed gauge and keep the gauge of the track. They have been changed from original wooden sleepers to concrete sleepers.

[0005] In view of the existing technology, the following problems exist:

[0006] In the actual use process of the existing railway tracks, the existing adjacent two railway tracks are directly fixed together by fastening bolts and fastening nuts. If the connection between the fastening bolts and the fastening nuts becomes loose, it will cause the adjacent two railway tracks to break, seriously affecting the normal operation of the railway and the safety of passengers. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following further describes the present utility model in detail with reference to the embodiments:

[0026] As Figures 1-5As shown in the figure, the utility model provides a railway rail fastening clip for preventing rail fractures, including a first rail 1. A second rail 2 is movably installed on one side of the first rail 1. A connecting mechanism 3 is installed between the first rail 1 and the second rail 2. A sleeper 4 is movably installed at the lower ends of the first rail 1 and the second rail 2. A fixing mechanism 5 is provided on one side of the sleeper 4. Through holes 6 are symmetrically and penetratingly opened in the middle parts of the first rail 1 and the second rail 2.

[0027] The number of the first through holes 6 is the same as that of the second through holes 32, and the inside of the first through holes 6 is movably connected to the outside of the long handle screws 33.

[0028] As Figures 3-4 shown, the connecting mechanism 3 includes a positioning plate 31. The positioning plate 31 is movably installed on the front and rear sides of the first rail 1 and the second rail 2. Four groups of second through holes 32 are equidistantly opened on the surface of the positioning plate 31. Long handle screws 33 are movably inserted into the inside of the second through holes 32. Nuts 34 are movably sleeved on the rear ends of the long handle screws 33. Sliders 35 are symmetrically and fixedly connected to the lower ends of the first rail 1 and the second rail 2. A chute frame 36 is movably installed on the outside of the sliders 35.

[0029] The external thread of the rear end of the long handle screw 33 is threadedly connected to the inside of the nut 34.

[0030] The slider 35 is in an "L" shape, and two groups of sliders 35 can form a complete "T" shape.

[0031] A T-shaped groove is penetratingly opened inside the chute frame 36. The slider 35 is fitted and movably installed in the T-shaped groove inside the chute frame 36.

[0032] By sliding the chute frame 36 into the outside of the slider 35, it can help the user fix the lower ends of the first rail 1 and the second rail 2, further enhancing the connection tightness between the two groups of rails. At the same time, the acting force between the first rail 1 and the second rail 2 can be further dispersed, making the connection between the two groups of rails more firm.

[0033] As Figure 5 shown, the fixing mechanism 5 includes a support plate 51. One end of the support plate 51 and the inner side of the sleeper 4 are symmetrically and fixedly connected. A bidirectional lead screw 52 is rotatably installed inside the support plate 51. Threaded seats 53 are threadedly connected to both sides of the outside of the bidirectional lead screw 52. A knob 54 is rotatably connected to the front end of the support plate 51. Clamping blocks 55 are fixedly connected to the upper ends of the threaded seats 53. Convex platforms 56 are opened on the opposite surfaces of the clamping blocks 55. A guide rod 57 is fixedly connected to the rear end inside the support plate 51. Guide blocks 58 are slidably installed on both sides of the outside of the guide rod 57.

[0034] One end of the threaded seat 53 is fixedly connected to the bottom end of the guide block 58.

[0035] The rear end of the knob 54 is rotatably installed on the top of the bidirectional lead screw 52.

[0036] The boss 56 is stepped, and the boss 56 on the clamping block 55 matches and is movably connected to the end faces of both ends of the first rail 1, the second rail 2, and the positioning plate 31.

[0037] When gradually approaching through the threaded seat 53, it will drive the guide block 58 to slide synchronously on the guide rod 57, and then the threaded seat 53 can be limited to make its movement stable.

[0038] The fixing structure also has an important protection function. When the long handle screw 33 breaks due to disrepair over the years or being unable to bear the load, the clamping force of the clamping block 55 can effectively prevent the connection of the rails from breaking and separating in this emergency situation, buying precious time for subsequent maintenance and handling. And this secondary fixing function is crucial for protecting the running safety of the bullet train. It provides additional safety guarantees for the running of the bullet train, ensuring that losses can be minimized to the greatest extent in case of emergencies.

[0039] Next, the working principle of the railway rail fastening clamp for preventing rail breakage will be specifically described.

[0040] As Figures 1-5 shown, when the railway rail fastening clamp for preventing rail breakage is in use, first, the user can place and align the first rail 1 and the rail, then place the positioning plate 31 on the front and back sides of the connection of the two groups of rails. At the same time, the through hole two 32 on the positioning plate 31 is in the same position as the through hole one 6. Then, pass the long handle screw 33 through the through holes in the positioning plate 31 and the two groups of rails, and then put the nut 34 on the long handle screw 33 and tighten it. By rotating the nut 34, the clamping force on the positioning plate 31 and the rails can be gradually increased, thereby firmly connecting and fixing the two groups of rails together. This connection method is not only simple and easy to operate but also has high reliability, ensuring that the rails will not loosen or separate easily during long-term use. After the rails are fixed, the chute frame 36 can be slid into the outside of the two groups of sliders 35, so that the rails can be closely fitted together; at the same time, the user can also rotate the knob 54 at the front end of the sleeper 4, so that the knob 54 drives the bidirectional lead screw 52 to rotate, making the bidirectional lead screw 52 drive the threaded seats 53 connected by threads on both sides to gradually approach, so that the threaded seats 53 can drive the clamping blocks 55 to move synchronously, making the bosses 56 opened on the clamping blocks 55 fit with the front and rear ends of the rails and the positioning plate 31, thereby further fixing the rails. And when the long handle screw 33 cannot bear the load pressure and breaks due to disrepair over the years, the clamping block 55 and the boss 56 can also help the user to perform secondary fixing on the first rail 1 and the second rail 2, thereby preventing the connection of the rails from breaking, enabling the user to minimize the damage caused, and protecting the running safety of the bullet train.

[0041] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are within the protection scope of the present utility model.
