Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and examples. It is to be understood that the embodiments described are some, but not all embodiments of the invention. The specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.
It should be noted that, in the present invention, the longitudinal direction refers to the direction of the length of the steel rail, i.e. the laying direction of the steel rail; the transverse direction is the direction of the width of the rail. Additionally, the utility model discloses a rail fastening still includes accessories such as bullet strip, bolt, gauge block. The present invention does not relate to the improvement of these accessories, and the skilled person in the art has the ability to understand and realize the functions of these accessories, so the present invention will not be described in detail.
As shown in fig. 1, the rail fastener of the present invention includes a metal base plate 10, a backing plate 14 and two spiral spikes.
In the present embodiment, as shown in fig. 2, two through holes 12 are provided at intervals on one diagonal line of the substrate 10. The two through holes 12 are used for inserting the screw spike. Two fixed seats are arranged on the other diagonal line of the substrate 10 at intervals. In particular, the two through holes 12 are distributed with central symmetry, and the two fixing seats are also distributed with central symmetry. Since the two holders are arranged on the top side of the base plate 10, the area for mounting the tie plate 14 is "Z" shaped.
In the present embodiment, as shown in fig. 3 to 5, the pad 14 is substantially "Z" shaped, and the pad 14 can be conformally disposed on the substrate 10. The backing plate 14 is provided with two mounting holes 16 at intervals, and the two mounting holes 16 correspond to the two through holes 12 respectively. The two mounting holes 16 are for the insertion of a screw spike. Two notches are arranged on the backing plate 14 at intervals and used for avoiding the two fixed seats. The underside of the backing plate 14 is provided with two retaining flanges 18, which two retaining flanges 18 are intended to be clamped on either side of the base plate 10 in the longitudinal direction. When the backing plate 14 is in a natural state, the transverse distance between the two mounting holes 16 is smaller than the transverse distance between the two through holes 12, and the longitudinal distance between the two limiting flanges 18 is larger than or equal to the longitudinal length of the base plate 10. When two screw spikes correspondingly pass through the two through holes 12 and the mounting holes 16, the backing plate 14 is transversely tensioned, the transverse distance between the two mounting holes 16 is increased, the longitudinal distance between the two limiting flanges 18 is reduced, and the two limiting flanges can be clamped on the two longitudinal sides of the base plate 10. Therefore, when mounting the mat 14, the mat 14 is first laid on the base plate 10, and then one side of the mat 14 is fixed by inserting a bolt pin into one mounting hole 16 and one through hole 12, respectively. Because the backing plate 14 is not tensioned at this time, the longitudinal distance between the two position-limiting flanges 18 is greater than or equal to the longitudinal length of the base plate 10, and the two position-limiting flanges 18 are not tightly clamped on the two longitudinal sides of the base plate 10. The tie plate 14 is then tensioned laterally, the lateral spacing of the two mounting holes 16 is increased so that the other mounting hole 16 of the tie plate 14 is aligned with the other through hole 12, and a screw spike is inserted into the mounting hole 16 and the through hole 12. At this time, since the pad 14 is tensioned, the longitudinal distance between the two position-limiting flanges 18 is reduced, and the two position-limiting flanges 18 can be tightly clamped on the two longitudinal sides of the base plate 10. Therefore, by providing two mounting holes 16, the backing plate 14 can be mounted and fixed on the base plate 10 by the screw spike; by providing two stop flanges 18, the shim plate 14 can be snapped tightly to the base plate 10 (which can be considered as forming an interference fit) without the shim plate 14 coming out from under the rails at all. In one embodiment of the present invention, the hardness of the position-defining flange 18 is greater than the hardness of the backing plate 14, which helps to keep the position-defining flange 18 tightly clamped against the longitudinal sides of the base plate 10. Thus, when the pad 14 is subjected to the forces exerted by the rail, the stop flange 18 does not easily deform to allow the pad 14 to move out from under the rail.
In one embodiment of the present invention, the bottom side of the backing plate 14 is provided with a textured or frosted surface. The textured or frosted surface makes the underside of the pad 14 rougher, thereby increasing the friction between the pad 14 and the base plate 10, making it more difficult for the pad 14 to be removed from under the rail.
In one embodiment of the present invention, the top side of the backing plate 14 is provided with a frosted surface or pattern. The textured or frosted surface roughens the top side of the pad 14, thereby increasing the friction between the pad 14 and the rail, increasing the longitudinal friction of the rail and helping to prevent rail movement.
In one embodiment of the present invention, the top side of the base plate 10 is provided with a frosted surface or pattern. The textured or sanded surface makes the top side of the base plate 10 rougher, thereby increasing the friction between the base plate 10 and the backing plate 14, making it more difficult for the backing plate 14 to move out from under the rails.
In one embodiment of the present invention, as shown in fig. 6, the angle between the backing plate 14 and the position-limiting flange 18 is a circular arc structure. That is, the angle between the backing plate 14 and the stop flange 18 transitions through a circular arc configuration. The arc structure actually increases the thickness of the corner, and also disperses the stress applied to the corner by the substrate 10, so that the portion is not easily broken.
In one embodiment of the present invention, the stop flange 18 is integrally formed with the backing plate 14. This advantageously increases the structural strength of the stop flange 18 and prevents the stop flange 18 from breaking away from the backing plate 14.
In one embodiment of the present invention, as shown in fig. 6, the width of the position-limiting flange 18 gradually increases from top to bottom. That is, the lower portion of the position-defining flange 18 is wider relative to the upper portion. Thus, the lower portion of the position-defining flange 18 is more tightly engaged with the base plate 10 and the connection between the backing plate 14 and the base plate 10 is more secure. In one embodiment of the present invention, the backing plate 14 is made of rubber, such as ethylene propylene diene monomer, nitrile rubber, or fluorocarbon rubber.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
