Description
Technical Field
[0001] The utility model relates to the technical field of railway sleeper spikes, in particular to a railway sleeper spike structure. Background Technique
[0002] Sleeper spikes are mainly used to fix the rail steel on the sleeper to ensure the stability and safety of the track. The rail steel is firmly connected to the sleeper through the sleeper spike, and can effectively withstand the huge impact force and vibration force generated during train operation, ensuring that the track does not shift during train driving.
[0003] However, since the sleeper spike needs to withstand huge impact force and vibration force, it needs to be overhauled and replaced regularly. When the traditional sleeper spike is disassembled and replaced, the spike needs to be directly pulled out from the flange of the rail steel. This operation not only requires a lot of effort, but also is easy to cause damage to the rail steel and the sleeper. In addition, since the spike is fixed very tightly, damage may be caused to the surrounding structural parts during the removal process. This disassembly and replacement method makes the workload of maintenance operations very large, the operation difficulty is high, which greatly affects the maintenance efficiency, and increases the cost and difficulty of railway maintenance.
[0004] Therefore, a railway sleeper spike structure is needed to solve the above technical defects. Content of the Utility Model
[0005] The purpose of the utility model is to provide a railway sleeper spike structure to solve the problems of very large workload of maintenance operations, high operation difficulty, greatly affecting the maintenance efficiency, and increasing the cost and difficulty of railway maintenance as mentioned in the above background technique.
[0006] To achieve the above purpose, the utility model provides the following technical solution: a railway sleeper spike structure, including a sleeper and a sleeper steel. A rail steel is arranged at the top of the sleeper, and a sleeper steel is arranged on the left side of the sleeper. A flange is integrally connected to the left side of the rail steel. A spike seat is assembled at the top of the sleeper steel. An inner groove penetrating both sides thereof is opened in the spike seat. The spike seat is sleeved outside the sleeper steel through the inner groove. A spike hole is opened at the top of the spike seat. A spike is driven into the spike hole. A wall groove is opened in the spike seat, and the wall groove is communicated with the spike hole. The right side of the spike is pressed above the flange. The spike seat is sleeved outside the sleeper steel. A first bolt is fixedly connected between the spike seat and the sleeper steel, and a second bolt is fixedly connected between the spike seat and the spike.
[0007] Preferably, mortise eyes are arranged on the inner side wall of the spike seat, and tenons are arranged at both ends of the top of the sleeper steel. The mortise eyes and the tenons are fitted and connected.
[0008] Preferably, the length of the spike seat is half of the length of the tenon, and the spike seat is assembled at the middle position of the top of the sleeper steel.
[0009] Preferably, the wall groove is a blind groove, which is provided on one end surface of the spike seat.
[0010] Preferably, a coil spring shaft is provided on one side of the spike seat, the coil spring shaft is assembled on the top of the pillow steel, a clamping rod is fixedly connected to the coil spring shaft, a clamping slot is provided on the top of the spike seat, and the clamping rod is clamped in the clamping slot.
[0011] Preferably, the coil spring shaft can be flipped upward at the pillow steel, and the clamping rod is arranged at an angle.
[0012] Preferably, the spike seats are evenly spaced on the top of the sleeper steel, and the number is set according to the length of the track.
[0013] Preferably, the top of the spike is arranged flat, and the portion of the spike covering the flange is two-thirds of the length of the top of the spike.
[0014] Compared with the prior art, the utility model has the following beneficial effects: the railway sleeper spike structure not only reduces the difficulty of maintenance operations, improves the efficiency of replacing spikes, and makes it impossible for the spike seat to be easily dislodged, thereby reducing the maintenance frequency of the entire rail, but also reduces the deformation and displacement of the spike seat caused by thermal expansion and contraction;
[0015] (1) The spike structure adopts a detachable spike and a spike seat for fixing. First, the spike seat is installed laterally from the top protrusion of the sleeper steel through the inner groove, and then horizontally moved to the middle position of the top of the sleeper steel. Four sets of first bolts are driven from the outer wall to fix the spike seat on the sleeper steel. Then, the spike is driven into the spike hole, and the second bolt is driven from one end of the outer wall of the spike seat to fix the spike and the spike seat, thereby achieving the fixation of the spike seat and the spike separately. The spike is driven into the spike hole, and two-thirds of the length of the straight section at the top is pressed and nailed above the flange of the track steel. When replacing the spike, the spike seat can be removed from the sleeper steel first, without directly pulling the spike from the flange. This greatly reduces the difficulty of maintenance operations and improves the efficiency of replacing spikes.
[0016] (2) The spike seat, tenon and mortise are provided. The spike seat is sleeved on the outside of the tenon, and the mortise inside is engaged with the tenon. Due to the existence of the tenon, the spike seat cannot be easily disengaged upward from the outside of the tenon. Therefore, the fixation of the spike to the flange has stronger stability, which improves the fixing effect of the entire spike structure on the rail steel, thereby ensuring the smoothness of the railway and driving safety, and reducing the maintenance frequency of the entire rail.
[0017] (3) By providing a coil spring shaft, a clamping rod, a clamping groove, a first bolt, and a spike base, with the coil spring shaft provided on the left side of the spike base, the coil spring can drive the clamping rod to flip. After the spike base is installed on the sleeper steel, flip the clamping rod and snap its top into the clamping groove. Based on the first bolt, add a set of clamping structures to improve the stability of the spike base and reduce the deformation and displacement of the spike base caused by thermal expansion and contraction.

[0025] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, this spike structure adopts a detachable cooperation of the spike 4 and the spike base 11 for fixation. First, the spike base 11 is installed from the side of the protrusion on the top of the sleeper steel 14 through the inner groove 10. After horizontally moving to the middle position on the top of the sleeper steel 14, four groups of first bolts 15 are driven in from the outer wall, so that the spike base 11 can be fixed on the sleeper steel 14. Then, the spike 4 is driven into the spike hole 5, and the second bolt 13 is driven in from one end of the outer wall of the spike base 11 to fix the spike 4 and the spike base 11, thus realizing the separate fixation of the spike base 11 and the spike 4.

Then, the spike 4 is driven into the spike hole 5, and the second bolt 13 is driven in from one end of the outer wall of the spike base 11 to fix the spike 4 and the spike base 11, thus realizing the separate fixation of the spike base 11 and the spike 4. The spike 4 is driven into the spike hole 5, and two-thirds of the length of the straight section at its top is pressed and nailed above the flange 3 of the rail steel 2. The spike base 11 is sleeved outside the tenon 9, and the mortise 16 inside it is fitted and connected with the tenon 9. Due to the existence of the tenon 9, the spike base 11 cannot easily be pulled out upwards from outside the tenon 9. A coil spring shaft 8 is provided on the left side of the spike base 11.
