[0004] Specifically, a conventional single-opening turnout comprises several sleepers 1, a fastener system, a straight stock rail 2, a curved stock rail 3, a straight connecting rail 4, a curved point rail, a guard rail 5, and a turnout mechanism. On the curved stock rail 3 side, the curved stock rail 3 and the guard rail 5 are secured to the sleeper 1 via a backing plate 6. The backing plate comprises a base plate 61, a table plate 62, a support plate 63, a support block 64, and an iron base 65. The base plate 61 is typically 170 mm wide, and the table plate 62 and iron base 65 are welded to the base plate 61.

[0005] For example, the patent with application number CN201220505147.2 discloses a rail guard plate for railway turnouts, which consists of a base plate, a table plate, a support plate, a support block and an iron seat. Two switch sleeper bolt holes are formed on the inner and outer sides of the base plate. An iron seat is fixed on the inner side of the upper end surface of the base plate, and the iron seat is located on the inner side of the inner switch sleeper bolt hole. A base plate is fixed on the outer side of the upper end surface of the base plate, and a large through hole is formed in the center of the base plate, and the large through hole is concentric with the outer switch sleeper bolt hole; a pair of support plates are fixed symmetrically on the front and rear of the upper end surface of the table plate, and the pair of support plates are located on both sides of the large through hole, a support block is fixed on the inner side of each support plate, and a horizontal bolt hole is formed on the upper part of each support plate.

[0006] For example, the patent with application number CN202210602168.4 discloses an anti-overturning guardrail pad, comprising: a bottom plate for carrying a basic rail, an iron seat, a fastener, a rail clip plate, a fixed platform plate for vertically carrying a guardrail, and a fixed support plate for horizontally fixing the guardrail, the iron seat and the fastener are used in conjunction with each other to fix a rail limb on one side of the basic rail, the rail clip plate is used to fix a rail limb on the other side of the basic rail, the fixed support plate is in contact with one side of the fixed platform and is all arranged on the rail clip plate, the rail clip plate, the iron seat and the fastener are all arranged on the bottom plate, the waist of the guardrail is connected to the fixed support plate, and also includes a clamp-shaped stopper, the upper part of the clamp-shaped stopper is a clamp-shaped bayonet structure, the lower part of the clamp-shaped stopper is a U-shaped double-rib structure, the two ends of the fixed platform are respectively connected to the U-shaped double-rib structure, and the clamp-shaped bayonet structure is gap-matched with the rail waist.

[0007] When the applicant used the existing guardrail pad, it was found that the force on the side of the curved basic rail 3 was much greater than that on the side of the straight basic rail 2. Correspondingly, the force between the table and the bottom plate was also very large; the pad at the curved basic rail 3 was easy to shift horizontally or the table was easy to loosen, which reduced the stability of the track.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] See also Figure 3-7 Embodiment 1 provides a one-piece large guardrail pad, comprising a plurality of pads 6 arranged side by side along the curved base rail 3. The pads 6 include a base plate 61, a table plate 62, a support plate 63, a support block 64, and an iron base 65. The base plate 61 is fixed to the corresponding sleeper 1 (via a switch sleeper bolt extending downward through a switch sleeper bolt hole 67) and has switch sleeper bolt holes 67 at both its inner and outer ends. The iron base 65 is welded to the base plate 61. The iron base 65 and the table plate 62 are located on the inner and outer sides of the curved base rail 3, respectively, and are both perpendicular to the curved base rail 3. The support plate 63 and the support block 64 are welded to the table plate 62. The support block 64 is welded to the inner side of the support plate 63 and is arranged along the direction of the table plate 62. The support plate 63 is arranged along the direction of the table plate 62 and is an outwardly open U-shaped plate. The upper portion of the support plate, located above the support block 64, has a guardrail bolt hole 68. The guardrail bolt hole 68 is perpendicular to the support plate 63. The guard rail 5 is placed on the support block 64 and fixed to the inner side of the support plate 63 (by means of guard rail bolts passing through the guard rail bolt holes 68). The curved base rail 3 is placed on the bottom plate 61 and sandwiched between the iron base 65 and the table 62. The above structure is consistent with the prior art, with the following differences:

[0032] In this embodiment, 2 to 3 base plates 61 are connected together by connecting plates 66 to form an I-shaped plate (similar structure, vertically inclined) or a W-shaped plate (similar structure, vertically inclined) to improve the stability of the base plate 61. The combination of 2 base plates 61 and 3 base plates 61 can basically cover all situations. There should not be too many connecting plates 66, otherwise it will be difficult to transport and store. The connecting plate 66 is set along the direction of the curved basic rail 3 and is located on the lower side of the curved basic rail 3. The base plate 61 and the connecting plate 66 are integrally formed (specifically, by milling the steel plate), and the table plate 62 is fixed to the base plate 61 by welding and bolting to improve the stability of the table plate 62. The guard rail 5 on the side of the curved basic rail 3 is usually fixed by 5-7 pads 6. For a five-rail system, two base plates 61 can be connected to form an I-shaped plate, and three base plates 61 can be connected to form a V-shaped plate. For a six-rail system, three base plates 61 can be connected to form a V-shaped plate, and three base plates 61 can be connected to form a V-shaped plate. For a seven-rail system, two base plates 61 can be connected to form an I-shaped plate, two base plates 61 can be connected to form an I-shaped plate, and three base plates 61 can be connected to form a V-shaped plate. A conventional pad structure is used on the straight base rail 2 side. Specifically, the sleeper 1 is a cement switch sleeper. The width of the base plate 61 is equal to the width of the sleeper 1 and is flush with the corresponding side of the sleeper 1. The connecting plate 66 is equal in thickness to the base plate 61 and its width is similar to that of the base plate 61.

[0033] Specifically, see Figure 3-7In this embodiment of the present invention, the platform 62 is securely connected to the base plate 61 via three reinforcing bolts 69. These bolts 69 are vertically positioned upward (with their heads located in countersunk holes 60) and are tightened by nuts on the top of the platform 62. Countersunk holes 60 (47mm in diameter) are located on the underside of the base plate 61 to accommodate the heads of the reinforcing bolts 69. Two of the reinforcing bolts 69 are located on the inner end of the platform 62, one on either side of the support block 64. The other is located on the outer end of the platform 62, within the opening of the support plate 63. Specifically, the reinforcing bolts 69 are M24*85 in size.
