At the same time, in the description of the present utility model, terms such as "first", "second", etc. are only used for differential description and cannot be construed as indicating or implying relative importance.
[0025] As Figure 1 shown, a fastening structure for a shoulder-type track includes: a height-adjusting pad 1, the cross-section of the height-adjusting pad 1 is in a "concave" shape, a pad structure 2 is provided in the middle of the top surface of the height-adjusting pad 1, and there is a pad gap between the end of the pad structure 2 and the end of the height-adjusting pad 1; a distance-adjusting structure 3, the cross-section of the distance-adjusting structure 3 is in the shape of the Arabic numeral "7", one end of the distance-adjusting structure 3 is arranged on the pad structure 2, the other end of the distance-adjusting structure 3 is arranged in the pad gap, and the distance-adjusting structure 3, the height-adjusting pad 1 and the pad structure 2 are all fixed on the lightweight sleeper by an anchor bolt 6; a fixing structure 4, one end of the fixing structure 4 is in contact with the distance-adjusting structure 3, the other end of the fixing structure 4 is provided with a gauge block 5, and the gauge block 5 and the distance-adjusting structure 3 adjust the gauge of the rail through the fixing structure 4.
[0026] The working process of this structure is as follows: adjusting the height of the distance-adjusting structure 3, the distance-adjusting structure 3 cooperates with the gauge block 5 to adjust, solving the stepless adjustment of the rail gauge. The common setting of the height-adjusting pad 1 and the distance-adjusting structure 3 effectively resists the lateral force, ensuring the strength and smoothness of the fastener. The common setting of the distance-adjusting structure 3, the gauge block 5, the height-adjusting pad 1 and the pad structure 2 solves the problem that the geometric dimensions of the track are greatly affected when a large number of trains pass through, resulting in the inability to guarantee the comfort and stability of the train running.
[0027] Preferably, the height of the height-adjusting pad 1 is adjusted by 10 mm, and the rail gauge is -16 mm to +16 mm.
[0028] As Figure 2 shown, the distance-adjusting structure 3 includes a distance-adjusting plate 31, the distance-adjusting plate 31 is arranged on the pad structure 2, a groove is opened at one end of the distance-adjusting plate 31, and the anchor bolt 6 passes through the groove to fix the distance-adjusting plate 31 on the lightweight sleeper. In this structure, by adjusting the height of the distance-adjusting plate 31, the end of the anchor bolt 6 and one end of the fixing structure 4 in contact with the distance-adjusting plate 31 are driven to move. The distance-adjusting plate 31 has better load-bearing capacity and stability. Preferably, the distance-adjusting plate 31 is wedge-shaped.
[0029] As Figure 3As shown in the figure, to clarify the specific structure of the distance adjustment plate 31, the distance adjustment plate 31 includes a special-shaped plate 311 and a trapezoidal plate 312. A groove is provided on the edge surface of the special-shaped plate 311 close to the fixed structure 4. The anchor bolt 6 passes through the groove to fix the special-shaped plate 311 on the lightweight sleeper. The end of the special-shaped plate 311 is fixedly connected to the trapezoidal plate 312.
[0030] In the present utility model, the distance adjustment structure 3 includes a distance adjustment block 32. The distance adjustment block 32 is arranged in the gap between the pads. One end of the distance adjustment block 32 extends towards the end away from the lightweight sleeper, and the extended end of the distance adjustment block 32 is fixedly connected to the end of the distance adjustment plate 31. The distance adjustment block 32 is arranged between the height adjustment pad 1 and the pad structure 2, increasing the contact surface between the distance adjustment structure 3 and the pad structure 2. The combined setting of the distance adjustment block 32 and the distance adjustment plate 31 can better adjust the position of the rail to adapt to different gauge requirements.
[0031] To clarify the specific setting of the gauge block 5, the cross-section of the gauge block 5 is in the shape of "L". The outer wall surface of the gauge block 5 contacts the fixed structure 4, and the inner wall surface of the gauge block 5 contacts the rail. The fixed structure 4 abuts and fixes the fold angle of the gauge block 5 on the rail. The gauge block 5 has good resilience, avoiding the risk of the anchor bolt 6 being sheared.
[0032] In this structure, the pad structure 2 includes an under-sleeper pad 21. The cross-section of the under-sleeper pad 21 is rectangular. The bottom surface of the under-sleeper pad 21 is arranged in the middle of the top surface of the height adjustment pad 1. The under-sleeper pad 21 is fixed on the lightweight sleeper by the anchor bolt 6. A gap is provided between the under-sleeper pad 21 and the height adjustment pad 1. The setting of the under-sleeper pad 21 improves the distribution of the load on the contact surface, reduces stress concentration, and improves the smoothness of the rail surface.
[0033] To clarify the mating structure between the pad structure 2 and the distance adjustment plate 31, the pad structure 2 includes a base plate 22. The bottom surface of the base plate 22 is arranged on the top surface of the under-sleeper pad 21. The top surface of the base plate 22 contacts the distance adjustment plate 31, and the end of the base plate 22 contacts the distance adjustment block 32. Preferably, a rail seat slope of 1:40 is provided on the base plate 22.
[0034] Furthermore, the cross-sectional length of the under-sleeper pad 21 is less than the cross-sectional length of the base plate 22.
[0035] As Figure 3As shown, the fixing structure 4 includes an iron seat 41. The iron seat 41 is arranged on the iron pad 22. One end of the iron seat 41 contacts the distance adjusting structure 3, and the other end of the iron seat 41 contacts the gauge block 5. The iron seat 41 is used to prevent the vertical and lateral forces generated when the train passes from causing the rail to be impacted and fall off or shift.
[0036] In this structure, the fixing structure 4 includes a spring clip 42 and a T-bolt 43. The spring clip 42 is in a "ω" shape. The T-bolt 43 passes through the middle limb of the spring clip 42, presses one end of the spring clip 42 against the outer wall surface of the gauge block 5, and the other end of the spring clip 42 presses against the top surface of the iron seat 41. The spring clip 42 is used to bear the weight of the train. The spring clip 42 can relieve the impact force and absorb shock, ensuring the safety of the train during operation.
[0037] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
[0038] As mentioned above, the above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or replacements, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
