[0039] 600, Spiral Rail Spike. Detailed Implementation

[0040] 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 protection scope of the present utility model.

[0041] This utility model provides, for example Figures 1-5 An insulated gauge baffle for heavy-duty railway rail fasteners, as shown, includes:

[0042] The base 100 can withstand the enormous pressure and impact generated during train operation, providing a solid platform for the subsequent installation of track components. The base 100 has a pre-embedded sleeve 110 that can be detachably and fixedly installed with the spiral spike 600. By screwing the spiral spike 600 into the pre-embedded sleeve 110, a reliable connection structure can be formed. This detachable design has significant advantages. When the track needs maintenance, repair, or component replacement, the spiral spike 600 can be easily and quickly removed from the pre-embedded sleeve 110 without damaging the base 100. A rail pad 120 is provided between the inner bottom wall of the placement groove 200 and the lower surface of the rail 300. On the one hand, it can buffer the impact force on the rail 300 during train operation, and evenly distribute the huge dynamic load to the inner bottom wall of the placement groove 200, avoiding excessive local pressure that could lead to structural damage. On the other hand, the rail pad 120 can also play a certain role in shock absorption and noise reduction, reducing the transmission of vibration and noise generated during train operation to the surrounding environment, improving the comfort of train operation and the quality of the surrounding environment.

[0043] The groove 200, which is located on the top of the base 100, provides positioning and support for components such as the rail 300, and can also buffer the vibration transmitted to the base 100 when the train is running to a certain extent, thus protecting the structural integrity of the base 100.

[0044] Rail 300 is placed inside the placement groove 200;

[0045] Two elastic bars 400 are provided and placed inside the placement groove 200. They are used to press down on both sides of the rail 300. They can generate elastic deformation when the train is running, absorb and disperse the impact force of the train on the rail 300, and prevent the rail 300 from being displaced or damaged due to excessive vibration.

[0046] The gauge baffle assembly 500 has two components, which are installed inside the placement groove 200 to prevent safety accidents such as derailment during train operation. The gauge baffle assembly 500 can also enhance the connection stability between the rail 300 and the base 100 and improve the reliability of the entire track structure.

[0047] The spiral rail spike 600 passes downward through the rail 300 and the gauge baffle assembly 500 and is inserted into the base 100. Through the fixing effect of the spiral rail spike 600, the rail 300, the gauge baffle assembly 500 and the base 100 can work together to withstand the various forces generated when the train is running, ensuring the safety and smooth operation of railway transportation.

[0048] In use, first adjust the length of the gauge baffle assembly 500 according to the requirements, then install the rail 300 and the spring strip 400 in sequence inside the placement groove 200, then fasten the baffle assembly 500 to the outside of the spring strip 400 and press down the rail 300, then pass the spiral rail spike 600 through the baffle assembly 500 and the spring strip 400 and fix it inside the base 100.

[0049] In some embodiments of this utility model, the gauge baffle assembly 500 includes:

[0050] The center plate 510 has insertion holes 511 on both sides to enable precise connection with other components. A metal liner 512 is detachably fixed inside the insertion hole 511. The metal liner 512 is precisely placed inside the insertion hole 511 and fixed in place by means of detachable fixing methods such as snap-fit ​​or bolt connection.

[0051] There are two side plates 520, located on both sides of the center plate 510 and closely fitted to it. They are partially inserted into the insertion through holes 511. A metal insert plate 521 is fixedly installed on the side of the side plate 520 near the center plate 510. The metal insert plate 521 is inserted into the metal liner 512 and fixed by bolts. These bolts are of precise specifications and can generate sufficient preload after tightening to firmly fix the metal insert plate 521 inside the metal liner 512, preventing loosening or displacement during use. A sealing rubber 522 is bonded between the side plate 520 and the center plate 510. The sealing rubber 522 wraps around the outer surface of the metal insert plate 521. It can not only prevent external dust, moisture and other impurities from entering the structure, but also play a certain role in buffering and shock absorption.

[0052] The reinforcement components 530, which are provided in two sets and installed on the outside of the center plate 510 and the side plate 520, can apply stable pressure to the connection between the center plate 510 and the side plate 520 from the outside to prevent loosening or displacement during use.

[0053] The overall length of the gauge baffle assembly 500 can be adjusted by the cooperation of the metal insert plate 521 and the metal liner plate 512, so as to adapt to the size of the gauge baffle base and the spring strip 400 of different specifications, thereby improving the applicability and convenience of use.

[0054] By setting the reinforcement component 530, the load-bearing capacity at the connection between the center plate 510 and the side plate 520 is increased, preventing the connection between the center plate 510 and the side plate 520 from breaking or bending under the action of external force, thereby improving the load-bearing strength of the gauge baffle assembly 500.

[0055] In some embodiments of this utility model, the reinforcement component 530 includes:

[0056] Two tracks 531 are provided and are fixedly installed on the outer sides of the center plate 510 and the side plate 520 respectively to ensure that other components can slide smoothly within them;

[0057] The reinforcing metal 532 is slidably inserted into the interior of the two rails 531. The reinforcing metal 532 is usually made of alloy steel with good toughness and strength. After a special heat treatment process, it has higher strength and resistance to deformation and can withstand greater external forces.

[0058] The elastic protrusion 533 is bonded to the outside of the reinforcing metal 532. The elastic protrusion 533 is designed in a hemispherical shape. This shape can provide a uniform pressure distribution when in contact with other components, while having good elastic deformation ability. When the reinforcing metal 532 is inserted into the track 531, the elastic protrusion 533 can play a role in buffering and positioning.

[0059] The positioning groove 534 is formed on the inner surface of the track 531 and inserted into the interior of the elastic protrusion 533, further enhancing the connection stability between the reinforcing metal 532 and the track 531.

[0060] The working method of this utility model:

[0061] First, adjust the length of the gauge baffle assembly 500 according to the requirements. Then, install the rail 300 and the spring strip 400 inside the placement groove 200 in sequence. Then, fasten the baffle assembly 500 to the outside of the spring strip 400 and press down the rail 300. Then, the spiral rail spike 600 passes through the baffle assembly 500 and the spring strip 400 and is fixed inside the base 100.

[0062] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
