[0031] Embodiment 1:

[0032] See also Figure 1 This embodiment provides a position-limiting anchoring device with a shoulder fastener, comprising:

[0033] A sleeper 1, with sleeper shoulders 11 provided on both sides of the sleeper 1, the sleeper shoulders 11 and the rail-bearing surface of the sleeper 1 forming a first angle;

[0034] The elastic pad 4 under the iron pad is arranged on the upper plane of the sleeper 1, and a first semicircular arc 41 is formed on the elastic pad 4 under the iron pad;

[0035] An iron pad 5, which is arranged on the elastic pad 4 below the iron pad, and has a through hole 51 and a second semicircular arc 52;

[0036] The rail-under elastic pad 8 is arranged on the upper plane of the iron pad 5;

[0037] A limit anchor 2, the limit anchor 2 passes through the first semicircular arc 41 and the second semicircular arc 52 and is connected to the sleeper 1; and

[0038] The fixing member 3 passes through the through hole 51 and is connected to the iron backing plate 5 .

[0039] When in use, the limit anchor device can flexibly adjust the distance and height of the rail 7. In general maintenance situations, it is only necessary to adjust the distance and height of the rail 7 by adjusting the fixing member 3. The limit anchor 2 is only adjusted when the height and distance adjustment amount is large, effectively avoiding frequent re-tightening of the casing that affects the service life of the casing.

[0040] Furthermore, the limiting anchor 2 includes an anchor bolt 21, a spring washer 22, a flat washer 23 and a distance adjusting baffle 24. The anchor bolt 21 passes through the spring washer 22, the flat washer 23 and the distance adjusting baffle 24 in sequence and is connected to the embedded sleeve 25. The embedded sleeve 25 is pre-fixed in the sleeper 1. After tightening, the anchor bolt 21 and the embedded sleeve 25 in the limiting anchor 2 generate a certain pre-tightening force, thereby fixing the elastic pad 4 under the iron pad and the upper structure on the sleeper 1.

[0041] Furthermore, the side surface of the distance adjusting baffle 24 is in contact with the surface of the sleeper shoulder 11, the first bottom surface 241 of the distance adjusting baffle 24 is in contact with the rail-bearing surface of the sleeper 1, and the second bottom surface 242 of the distance adjusting baffle 24 is in contact with the iron pad 5; the bottom of the distance adjusting baffle 24 in the limiting anchor 2 is in contact with the sleeper 1 to prevent the elastic pad 4 under the iron pad from being excessively compressed, effectively ensuring the elasticity of the fastener, and the distance adjusting baffle 24 and the sleeper shoulder 11 are mutually limited, and the wheel-rail lateral force exerted on the fastener passes through the limiting anchor 2 to the sleeper shoulder 11, thereby optimizing the fastener force structure, reducing the lateral force exerted on the anchor bolt 21, improving the lateral stiffness of the track structure, reducing the dynamic gauge expansion, and improving the lateral stability of the track, which is beneficial to controlling abnormal creep contact and thus reducing the generation of corrugation.

[0042] Furthermore, a cylindrical through hole 243 is provided on the distance adjustment baffle 24, and the outer surface of the cylindrical through hole 243 is in contact with the inner surface of the first semicircular arc 41 and the second semicircular arc 52; Figure 3 As shown, during the actual assembly process, the limiting anchor 2 pre-assembles the iron pad 5 and the elastic pad 4 under the iron pad onto the sleeper 1, which greatly reduces the workload of on-site construction, and the distance adjustment baffle 24 is structurally compatible with the iron pad 5 and the elastic pad 4 under the iron pad, which greatly improves the integrity of the fastener.

[0043] Furthermore, a protrusion is provided at the lower portion of the distance adjusting baffle 24, a groove is provided at the side position of the elastic pad 4 under the iron pad, and a groove is provided at the side position of the iron pad 5. The protrusion of the distance adjusting baffle 24 matches with the groove of the elastic pad 4 under the iron pad, and the protrusion of the distance adjusting baffle 24 matches with the groove of the iron pad 5; a protrusion is provided at the lower portion of the distance adjusting baffle 24 of the limiting anchor 3, which matches with the grooves on both sides of the iron pad 5 and the elastic pad 4 under the iron pad, so as to limit the displacement of the iron pad 5 and the elastic pad 4 under the iron pad along the direction of the rail 7. The distance adjusting baffle 24 has a variety of width specifications, which can be selected according to actual needs. The horizontal and gauge adjustments of the rail 7 can be achieved through different specification configurations.

[0044] Furthermore, the fixing member 3 includes a T-bolt 31, a lock nut 32 and an elastic bar 33. The T-bolt 31 passes through the lock nut 32 and the elastic bar 33 in sequence and is connected to the iron pad 5. One end of the elastic bar 33 contacts the iron seat on the iron pad 5, and the other end of the elastic bar 33 contacts the insulating gauge block 6. The gauge block 6 contacts the rail 7. The fixing member 3 is used to buckle the rail 7 to prevent the rail 7 from overturning and play a retaining role.

[0045] Furthermore, an iron plate lower height adjustment pad 9 is provided between the sleeper 1 and the iron plate lower elastic pad 4, and the lower surface of the iron plate lower height adjustment pad 9 and the hypotenuse form a second angle, and the outer surface of the second angle fits the inner surface of the first angle; Figure 2As shown, the iron pad lower height adjustment pad 9 is used to achieve a large-scale height adjustment, and can play a role in vertical and lateral limiting, making the entire structure more stable and reliable.

[0046] Furthermore, a rail height adjustment pad 10 is provided between the iron pad 5 and the rail elastic pad 8; Figure 2 As shown, the under-rail height adjustment pad 10 is used to achieve a relatively small height adjustment.

[0047] Furthermore, the diameter of the anchor bolt 21 is 24 mm.

[0048] Furthermore, at least two through holes 51, first semicircular arcs 41, second semicircular arcs 52, position-limiting anchors 2 and fixing members 3 are provided.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
