Description

TECHNICAL FIELD

[0001] The utility model relates to a sleeper field, concretely relates to a wide track gauge sleeper for ordinary section and guard rail section. BACKGROUND

[0002] Track is important infrastructure in railway construction, and good track structure is an important guarantee for safe and reliable railway operation, comfort and high efficiency. Sleeper is a key component in track structure, and its main functions include two aspects: on the one hand, it bears various loads from steel rails and transmits them to the lower track bed; on the other hand, it effectively maintains the track gauge, track orientation and other geometric shapes of the railway line. In the prior art, the standard track gauge of 1435mm is an economic and efficient track gauge standard, which can meet the transportation needs of most railways in China, but cannot meet the needs of all operating lines, such as some port railways. In addition, for the track structure of the standard track gauge, the support area of the sleeper on the track bed is small, and the phenomenon of track subsidence is prone to occur. Therefore, it is necessary to carry out research on the track structure of wide track gauge. SUMMARY

[0003] The utility model provides a wide track gauge sleeper for ordinary section and guard rail section, to solve the problem that the sleeper matched with the standard track gauge in the prior art has insufficient adaptability and is prone to cause track subsidence, and realize the purpose of being able to adapt to wider track gauge working conditions.

[0004] The utility model realizes the following technical schemes:

[0005] A wide track gauge sleeper for ordinary section and guard rail section, comprising a sleeper main body, a prestressed steel bar fixed in the sleeper main body, the sleeper main body having a shoulder, further comprising a metal reinforcing member located in the sleeper main body, the metal reinforcing member being opposite to the shoulder, and the metal reinforcing member being fixedly connected with the prestressed steel bar.

[0006] In order to solve the problems of the existing track tie with the standard track gauge, such as poor adaptability and easy to cause track subsidence, the utility model provides a wide track gauge track tie for common section and guard rail section, and those skilled in the art should understand that the prestressed steel is arranged in the concrete track tie body, and the shoulder is arranged on the track tie body, which are prior art. When the track structure with wide track gauge is researched, the length of the track tie must be increased. However, the inventors found that if the length of the concrete track tie is simply increased, cracks are prone to occur at the shoulder of the track tie under the action of train load. Based on the above research, the metal reinforcing member is arranged in the track tie body, and the metal reinforcing member is corresponded to the shoulder of the track tie, and the metal reinforcing member is fixedly connected with the prestressed steel in the concrete track tie. After the track tie body is formed, the metal reinforcing member and the prestressed steel are fixed in the concrete.

[0007] The track tie structure is more suitable for the wide track gauge working condition, the risk of cracking of the track tie is reduced under the premise of increasing the length of the track tie, and then the overall stability of the wide track gauge track is improved, and more railway transportation demands are met.

[0008] Further, the metal reinforcing member is partially or entirely located in the shoulder. The cracking risk of the shoulder is reduced.

[0009] Further, the metal reinforcing member comprises a plurality of transverse ribs extending along the length direction of the track tie body and a plurality of longitudinal ribs fixed between adjacent transverse ribs. The length direction of the track tie body refers to the direction of the connecting line from one end to the other end of the track tie in the transverse direction. The metal reinforcing member is obtained by connecting the plurality of transverse ribs and the plurality of longitudinal ribs, which is more conducive to ensuring the crack resistance of the track tie under the wide track gauge working condition.

[0010] Further, the two ends of the longitudinal rib are respectively welded with the adjacent two transverse ribs, so as to ensure the structural integrity of the metal reinforcing member, and facilitate the positioning and installation of the metal reinforcing member during the production of the track tie.

[0011] Further, the transverse rib comprises a main rib section, a first turning section located at two ends of the main rib section, and a first extension section located at one end of the first turning section away from the main rib section; the height of the first extension section is higher than the height of the main rib section.

[0012] The transverse rib is divided into three parts, two ends of which are the first extension section, and the middle part is the main rib section, and the first turning section is between the first extension section and the main rib section; since the height of the first extension section is higher than the height of the main rib section, the first turning section in the present application is inclined upward from one end close to the main rib section to one end close to the first extension section. The transverse rib with such structure can better adapt to the shoulder structure, and is more conducive to improving the crack resistance of the shoulder.

[0013] Further, the first extension section is completely located in the retaining shoulder; and whether the main reinforcement section and the first turning section are located in the retaining shoulder can be adaptively set according to specific working conditions.

[0014] Further, the top surface of the retaining shoulder has a rail bottom mounting groove, the main reinforcement section is located below the rail bottom mounting groove, and the first extension sections on both sides are located on the two sides of the rail bottom mounting groove. Those skilled in the art should understand that the rail bottom mounting groove is prior art on the retaining shoulder and is used for mounting a steel rail and a fastener; the present scheme makes the first extension sections on both sides located on the opposite sides of the rail bottom mounting groove, which can be more suitable for wide track gauge working conditions, and improves the crack resistance of the retaining shoulder and the overall stability of the wide track gauge track.

[0015] Further, the slope of the groove bottom of the rail bottom mounting groove is 1 / 20 or 1 / 40; corresponding to different angles of the rail bottom slope, the rail bottom mounting groove can be adaptively selected according to different line requirements.

[0016] Further, the metal reinforcing member further comprises an auxiliary rib fixedly connected with the at least one longitudinal rib; the auxiliary rib extends towards the outside direction of the retaining shoulder, and the auxiliary rib comprises a second turning section opposite to the first turning section on the same side and a second extension section opposite to the first extension section on the same side.

[0017] In the present scheme, the outside direction of the retaining shoulder refers to a direction along the length direction of the sleeper main body and closer to the end surface of the sleeper main body corresponding to the retaining shoulder. The present scheme sets the auxiliary rib in the outside direction of the retaining shoulder, connects the auxiliary rib through the at least one longitudinal rib, and makes the second turning section on the auxiliary rib correspond to the first turning section in the side direction and the second extension section correspond to the first extension section in the side direction, thereby ensuring the integrity of the metal reinforcing member. Such arrangement can significantly enhance the structural strength of the outside of the retaining shoulder which bears more stress, improve the crack resistance of the concrete around the retaining shoulder, and also facilitate the identification of the inside and outside of the metal reinforcing member and the quick positioning and installation in the production process.

[0018] Further, the metal reinforcing member and the prestressed steel bar are connected through a fixing member; the positioning and installation of the metal reinforcing member can be realized before the sleeper main body is formed, the metal reinforcing member is ensured to be located in a specified position, and the stability of the metal reinforcing member in the process of pouring and forming the sleeper main body is ensured.
