Description

Technical Field

[0001] The utility model relates to the technical field of track fasteners, and more specifically, to a train track fastener. Background Art

[0002] High-speed railway tracks are an important part of modern transportation. They undertake the task of running high-speed trains and play a decisive role in the safety, stability and comfort of the railway. High-speed railway tracks mainly consist of rails, sleepers, ballast beds, connecting parts, etc. These components together constitute the basis for train running. When fixing the track, fasteners are needed to fix the track on the sleeper.

[0003] At present, when using the existing fastener, the elastic strip is pressed on the track by tightening the bolt. Although this can achieve the purpose of fixing the track, due to the small contact area between the elastic strip and the track, the stability of the elastic strip when pressing the track is not high. Therefore, we propose a train track fastener to solve the above problems. Summary of the Utility Model

[0004] 1. Technical Problems to be Solved

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a train track fastener. By setting an elastic plate and a pressing plate, when fastening the rail, the bolt is tightened. At this time, under the action of the elastic plate, the pressing plate can be extruded, and then the pressing plate can stably press on the rail. Since the contact area between the pressing plate and the rail is relatively large, when fastening, the fastening area can be increased, thereby improving the stability when fixing the rail.

[0006] 2. Technical Solutions

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A train track fastener includes a sleeper and a rail. The rail is located at the upper end of the sleeper. Inside the upper end of the sleeper, there are two gauge blocks, which are located on both sides of the rail. At the end of the gauge block close to the rail, there is a pressing plate. Elastic plates are arranged on the upper ends of the pressing plate and the gauge block. Inside the sleeper, there is a pre-embedded pipe. A bolt is threadedly connected inside the pre-embedded pipe. The bolt penetrates through the elastic plate and the gauge block. A washer is arranged between the bolt and the elastic plate, and the washer is sleeved on the bolt.

[0009] Furthermore, a backing plate and a buffer plate are arranged between the sleeper and the rail, and the backing plate and the buffer plate are distributed in sequence from bottom to top.

[0010] Furthermore, through holes are formed on the surface of the elastic plate, and the diameter of the washer is larger than the width of the through hole.

[0011] Further, a circular hole is formed in the upper end surface of the gauge retaining plate, and the diameter of the circular hole is larger than the diameter of the bolt.

[0012] Further, a connecting groove is formed in the surface of the gauge retaining plate close to the pressing plate, a connecting block is slidably connected inside the connecting groove, and the connecting block is fixedly connected to the pressing plate; the end face shapes of the connecting block and the connecting groove are both in the shape of a dovetail groove.

[0013] Further, the pressing plate is in an inverted L shape, and a retaining strip is fixedly connected to the upper end of the pressing plate.

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] In this solution, by providing an elastic plate and a pressing plate, when pressing and buckling the rail, the bolt is tightened. At this time, under the action of the elastic plate, the pressing plate can be extruded, and then the pressing plate can be stably pressed on the rail. Since the contact area between the pressing plate and the rail is relatively large, when buckling, the buckling area can be increased, thereby improving the stability when the rail is fixed.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the attached drawings of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-5 , a train track buckle, including a sleeper 1 and a rail 2. The rail 2 is located at the upper end of the sleeper 1. Inside the upper end of the sleeper 1, there are two gauge blocks 3, which are located on both sides of the rail 2. At one end of the gauge block 3 close to the rail 2, there is a pressing plate 7. Elastic plates 6 are arranged on the upper ends of the pressing plate 7 and the gauge block 3. Inside the sleeper 1, there is a pre-embedded pipe 11. A bolt 4 is threadedly connected inside the pre-embedded pipe 11. The bolt 4 passes through the elastic plate 6 and the gauge block 3. A washer 5 is arranged between the bolt 4 and the elastic plate 6, and the washer 5 is sleeved on the bolt 4.

[0026] Specifically, when in use, place the rail 2 in the middle position at the upper end of the sleeper 1, then install the gauge blocks 3 on both sides of the rail 2. After the gauge blocks 3 are installed, press the pressing plate 7 on the rail 2, then place the elastic plates 6 on the upper ends of the pressing plate 7 and the gauge block 3. Finally, pass the bolt 4 through the washer 5, the elastic plate 6 and the gauge block 3, and then turn the bolt 4. With the cooperation of the pre-embedded pipe 11, the bolt 4 can move downward. After the bolt 4 contacts the washer 5, at this time, as the bolt 4 is further tightened, the elastic plate 6 can be squeezed to press the pressing plate 7, and then the pressing plate 7 can stably press on the rail 2. Since the contact area between the pressing plate 7 and the rail 2 is relatively large, when the rail 2 is buckled, the buckling area can be increased, thereby improving the stability when the rail 2 is fixed.

[0027] A backing plate 8 and a buffer plate 9 are arranged between the sleeper 1 and the rail 2, and the backing plate 8 and the buffer plate 9 are distributed in sequence from bottom to top. During operation, by arranging the backing plate 8 and the buffer plate 9, the vibration of the rail 2 can be buffered at this time, thereby reducing the damage of the rail 2 to the sleeper 1.

[0028] Through holes 10 are formed on the surface of the elastic plate 6, and the diameter of the washer 5 is larger than the width of the through holes 10. During operation, by arranging the through holes 10, it is convenient to install the bolt 4 at this time. At the same time, since the diameter of the washer 5 is larger than the width of the through holes 10, the bolt 4 can stably press the elastic plate 6.

[0029] A circular hole 12 is formed on the upper end surface of the gauge block 3, and the diameter of the circular hole 12 is larger than the diameter of the bolt 4. During operation, by arranging the circular hole 12, it is convenient for the bolt 4 to pass through the gauge block 3.

[0030] One side of the gauge retaining plate 3 close to the pressing plate 7 is provided with a connecting groove 13, and a connecting block 14 is slidably connected inside the connecting groove 13. The connecting block 14 is fixedly connected to the pressing plate 7. The end face shape of the connecting block 14 and the end face shape of the connecting groove 13 are both in the shape of a dovetail groove. During operation, by providing the connecting groove 13 and the connecting block 14, the pressing plate 7 can move stably when moving downward.

[0031] The pressing plate 7 is in an inverted L shape, and a retaining bar 15 is fixedly connected to the upper end of the pressing plate 7. During operation, by providing the retaining bar 15, not only can the installation of the elastic plate 6 be limited, but also the elastic plate 6 can stably press the pressing plate 7 under the action of the retaining bar 15.

[0032] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
