Detailed Description
The fastener shown in the figures 1 and 2 comprises an embedded sleeve 1, the embedded sleeve 1 is embedded in a sleeper, the fastener further comprises a base 2, a track gauge buckle plate 3 and a spiral spike nail 4, the base 2 is arranged on the sleeper, the track gauge buckle plate 3 is arranged on the base 2, through holes are formed in the base 2 and the track gauge buckle plate 3 to allow the spiral spike nail 4 to pass through, an adjusting notch 5 is formed in the track gauge buckle plate 3 as shown in the figure 4, the adjusting notches 5 are at least arranged on the track gauge buckle plate 3, and the two adjusting notches 5 can be compressed at the bottom of a steel rail through the angle of the adjusting track gauge buckle plate 3 to adjust a track gauge block and compress the bottom of the steel rail. Spiral spike 4 passes gauge buckle 3 and base 2 and is connected with buried sleeve 1 thereby it is fixed with base 2 and makes gauge buckle 3 compress tightly the rail foot, wherein adjust notch 5 and rail foot side contact site mainly adjust, consequently in order to make same gauge buckle 3 realize different gauge regulation, each adjust notch 5 and rail foot side contact site and spiral spike 4 central distance difference, the gauge just can realize the adjustment after changing different regulation notches 5 like this, and this kind has the effect of gauge piece with gauge buckle 3, the quantity of spare part in the knot reduction has been reduced, the wholeness is better, conveniently adjust and reduce the later maintenance cost.
Because the gauge buckle 3 needs to be positioned after being rotated to enable the corresponding adjusting notch 5 to be correspondingly buckled with the rail foot position of the steel rail, in order to realize the positioning of the gauge buckle 3, positioning pieces are arranged on the base 2 and the gauge buckle 3 to realize the positioning of the gauge buckle 3, the embodiment shown in the figure 3 and the figure 4 is further specifically used for further explanation, a positioning column 6 is arranged on the base 2, a positioning groove 7 is arranged on the gauge buckle 3, the required adjusting notch 5 is relatively buckled with the steel rail on the base 2 when the gauge is adjusted, the positioning column 6 is inserted into the positioning groove 7, the positioning of the gauge buckle 3 is realized, meanwhile, the position of the adjusting notch 5 matched with the steel rail can be ensured to be matched with the rail foot position of the steel rail, and the screw rail nail 4 type gauge buckle 3 can be prevented from being screwed. In order to further improve the limiting effect, a limiting groove 8 is further formed in the base 2, and one side of the gauge buckle plate 3 can be clamped into the limiting groove 8 to achieve positioning.
The above-mentioned gauge buckle 3 be provided with two at least and adjust notch 5, be in order to can realize the adjustment to the rail gauge of rail through changing different regulation notches 5, the scheme that is equipped with four regulation notches 5 on a gauge buckle 3 has been given here as shown in figure 4, the transversal cross that personally submits of this gauge buckle 3, two adjacent regulation notches 5 are in on gauge buckle 3 mutually perpendicular's two faces, consequently this gauge buckle 3 can realize the gauge adjustment of four kinds of sizes, only need only the regulation notch 5 on the different faces rotate to be relative with the rail and detain and give security at rail foot of a track position can. Only one embodiment is given here, in order to realize more size adjustment in practice, it is also possible to choose to provide more adjusting notches 5 such as 3 or 5 or 6 on the gauge buckle 3 to realize more size adjustment, corresponding structural design is not given in the figure any more, each adjusting notch 5 is arranged on a different side of the gauge buckle 3 with reference to the structure of fig. 4, and the positions of the adjusting notches 5 are adjusted by rotating the gauge buckle 3.
In order to enable the pressure on the screw spike 4 to be transmitted to the gauge buckle plate 3 more uniformly, and avoid the too small pressure of the contact area between the screw spike 4 and the gauge buckle plate 3 from damaging the gauge buckle plate 3, as shown in fig. 1 and fig. 2, a pressing plate 9 is further arranged on the upper surface of the gauge buckle plate 3, the contact area between the pressing plate 9 and the gauge buckle plate 3 is large enough, so that the pressure of the screw spike 4 can be uniformly transmitted to the gauge buckle plate 3, of course, the pressure of the screw spike 4 on the gauge buckle plate 3 is reduced by the scheme in the actual use, flange bolts can be used as the screw spike to increase the contact area, or elastic strips in the traditional fastener are adopted to compress tightly.
As shown in figure 1, in order to prevent the screw spike 4 from being subjected to excessive transverse shearing force, a retaining shoulder 10 abutting against the sleeper is arranged on the outer side of the base 2, and when the fastener is subjected to transverse acting force, the transverse acting force is transmitted to the sleeper through the retaining shoulder 10, so that the transverse force is reduced and is directly acted on the screw spike 4.
In the embodiment shown in fig. 1 and 2, two bases 2 are respectively arranged on two sides of a steel rail, and in order to increase the friction force between the bases 2 and the sleeper and avoid the rotation of the bases 2 when the spikes are screwed down, rough surfaces or bulges are arranged at the bottom of the bases 2 and are clamped into the sleeper. For better integrity and positioning, the bases 2 on both sides can be made into a whole as shown in fig. 5, the bottoms are connected together through a flat plate, and the steel rails are directly erected on the flat plate. In view of the above structure, since the base 2 can be separately arranged (as shown in fig. 3) or connected together to form a whole (as shown in fig. 5), when the base 2 is separately arranged, the assembly of the single-sided embedded sleeve 1, the base 2, the track-gauge buckle 3 and the screw spike 4 can be regarded as a complete fastener; and when two bases 2 form a whole through the flat connection, a complete fastener then includes two bases 2 as a whole and with these two bases 2 pre-buried sleeve 1, base 2, gauge buckle 3 and the screw spike 4 of mutually supporting.
