[0022] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0023] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present utility model, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] like Figure 1 As shown, this embodiment provides a mountain fastener system, which includes a sleeper 6, a fastening assembly, a gauge baffle 7, a baffle seat 4 and a limiting device; the fastening assembly includes a first fastening assembly and a second fastening assembly, the first fastening assembly and the second fastening assembly are symmetrically arranged on both sides of the rail 1, and the fastening assembly is used to fix the rail 1; the gauge baffle 7 is arranged between the fastening assembly and the rail 1; the baffle seat 4 is arranged between the sleeper 6 and the gauge baffle, and the contact surface between the baffle seat 4 and the sleeper 6 is an inclined surface; the limiting device is used to limit the baffle seat 4, and the limiting device includes a first limiting device 5 and a second limiting device 6. Two limit devices 8, the first limit device 5 and the second limit device 8 are symmetrically arranged on both sides of the rail 1. Since there are some special lines in mountain roads, underground and tourist routes, the slope is greater than 4‰, which leads to an increase in the lateral force of the wheel and rail, making the baffle seat 4 easy to slide out. Therefore, by symmetrically arranging the first limit device 5 and the second limit device 8 on both sides of the rail, the baffle seat 4 can be effectively prevented from sliding out. In addition, the contact surface between the baffle seat 4 and the sleeper 6 is an inclined surface, and the inclined surface is an obtuse angle, which can increase the accommodating space of the entire fastener system, thereby ensuring a large contact area for transmitting force to improve the stability of the system.

[0025] In a specific embodiment of the present disclosure, the gauge baffle 7 is tilted relative to the ground, the side of the gauge baffle 7 close to the baffle seat 4 is lower than the side close to the rail 1, and a first groove is provided on the side of the gauge baffle 7 close to the baffle seat 4. Due to the slope of the line, the force can be transmitted more to the bottom of the sleeper 6 by tilting the gauge baffle 7.

[0026] In a specific embodiment of the present disclosure, the first fastening assembly includes a spiral spike 2 and a spring clip fastener 3 . The spring clip fastener 3 is disposed between the spiral spike 2 and the track gauge baffle 7 . The spiral spike 2 is used to fix the spring clip fastener 3 .

[0027] In a specific embodiment of the present disclosure, the spiral spike 2 includes a connecting rod and a threaded rod, and the ratio of the length of the connecting rod to the length of the threaded rod is 1:1.5-2. Due to the loose soil in special environments such as mountain roads and underground, it is necessary to set the length of the threaded rod to be longer and buried in the soil to ensure the stability of the fastener system.

[0028] like Figure 2As shown, in a specific embodiment of the present disclosure, the spring clip fastener 3 includes a first buckling portion 9, a second buckling portion 10 and a connecting portion 11, the first buckling portion 9 and the second buckling portion 10 are connected by the connecting portion 11, the first buckling portion 9 includes a first sub-buckle portion 12, a sub-connecting portion 13 and a second sub-buckle portion 14, the first sub-buckle portion 12 and the second sub-buckle portion 14 are connected by the sub-connecting portion 13, the sub-connecting portion 13 and the first sub-buckle portion 12 are inclined, and the angle between the sub-connecting portion 13 and the first sub-buckle portion 12 is 60°-80°. In this embodiment, the angle between the sub-connecting portion 13 and the first sub-buckle portion 12 is set to 60°-80°, which is more reliable for force transmission compared to the right angle in the prior art.

[0029] like Figure 3 As shown, in a specific embodiment of the present disclosure, the first limiting device 5 includes a seismic sensor 15, a power supply device 16, a driving device, a limiting mechanism and a protective cover 18. The seismic sensor 15 is arranged on the power supply device 16. The power supply device 16 and the driving device are connected by a lead 17. The driving device is used to drive the limiting mechanism. The driving device and the limiting mechanism are arranged inside the protective cover 18. Since the entire fastener system requires a larger accommodation space to improve the stability of the system, the contact surface between the baffle seat 4 and the sleeper 6 is an inclined surface, which may cause the baffle seat 6 to slide out easily when an earthquake occurs. Therefore, the baffle seat 6 is limited by the first limiting device 5 to ensure the safe operation of the train. It should be noted that when the seismic sensor 15 detects an earthquake, the power supply device 16 supplies power to the driving device to limit the baffle seat 6.

[0030] In a specific embodiment of the present disclosure, the driving device includes an electromagnetic driver 19 and a guide rod 20. The electromagnetic driver 19 is used to drive the guide rod 20 to move. The side of the guide rod 20 close to the limiting mechanism is set to be arc-shaped.

[0031] In a specific embodiment of the present disclosure, the limiting mechanism includes a permanent magnet 23, an alloy rod 24, a limiting block 25, a first soft iron layer 21 and a second soft iron layer 22. The two ends of the alloy rod 24 are respectively connected to the permanent magnet 23 and the limiting block 25. The permanent magnet 23 and the alloy rod 24 are arranged between the first soft iron layer 21 and the second soft iron layer 22. When no earthquake occurs, the limiting mechanism does not limit the baffle seat 6, and does not affect the maintenance and parts replacement of the fastener system. When an earthquake occurs, the electromagnetic driver 19 is used to drive the guide rod 20 to move the limiting block 25 to extend the protective cover 18 to achieve the limitation of the baffle seat 6.

[0032] In a specific embodiment of the present disclosure, a cushion layer 26 is arranged between the first soft iron layer 21 and the second soft iron layer 22. The cushion layer 26 is arranged parallel to the ground. The cushion layer 26 is arranged on the side close to the sleeper 6. By arranging the cushion layer 26, the friction between the permanent magnet 23 and the protective cover 18 is avoided, and the speed at which the limit block extends out of the protective cover 18 is increased, so as to achieve a rapid response to limit the baffle seat 6 during an earthquake.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components.
