The rod 41 and the connecting member 4 slide toward each other, and a trigger switch 5 is provided inside the connecting member 4. Therefore, when the protective plate 1 is impacted, the cooperation of the connecting member 4, the connecting rod 41, the buffer unit and the trigger switch 5 can not only buffer the impact force on the protective plate 1 when the protective plate 1 is impacted, but also automatically notify the staff to repair the damaged protective plate 1 when the protective plate 1 is damaged, and the cooperation of the mounting member 2, the reinforcing member 3, the reinforcing rod 31 and the pulling unit can further buffer the impact force on the protective plate 1.

[0027] like Figures 1 to 3 As shown, the pulling unit includes a pulling plate 6 and a pulling spring 61, a receiving hole 21 is provided on the mounting member 2, one end of the reinforcing member 3 is rotatably arranged inside the receiving hole 21, a pulling cavity 62 is provided inside the reinforcing member 3, the pulling plate 6 is slidably arranged inside the pulling cavity 62, the pulling spring 61 is arranged between the pulling plate 6 and the inner wall of the pulling cavity 62, one end of the reinforcing rod 31 is arranged on the pulling plate 6, and the other end of the reinforcing rod 31 extends to the outside of the reinforcing member 3, so that through the cooperation of the pulling plate 6 and the pulling spring 61, the reinforcing member 3 and the reinforcing rod 31 provide an elastic traction force to both sides of the mounting member 2, thereby further buffering the impact force exerted on the protective plate 1.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the buffer unit includes a buffer seat 7, a buffer plate 71 and a buffer spring 72. The buffer seat 7 is symmetrically arranged on a side of the mounting member 2 close to the protective plate 1. The connecting member 4 is rotatably arranged on the buffer seat 7. A buffer cavity 73 is arranged inside the connecting member 4. The trigger switch 5 is arranged on the inner wall of the buffer cavity 73. When the protective plate 1 is intact, there is a gap between the buffer plate 71 and the trigger switch 5. The buffer plate 71 is slidably arranged inside the buffer cavity 73. The buffer spring 72 is arranged between the buffer plate 71 and the inner wall of the buffer cavity 73. One end of the connecting rod 41 is arranged on the buffer plate 71, and the other end of the connecting rod 41 extends to the outside of the connecting member 4. Therefore, through the cooperation of the buffer seat 7, the buffer plate 71 and the buffer spring 72, the connecting member 4 and the connecting rod 41 provide an elastic traction force to both sides of the protective plate 1. At the same time, the trigger switch 5 can also automatically notify the staff to repair the damaged protective plate 1.

[0029] like Figure 2 and Figure 5 As shown, a mounting plate 22 is provided on the bottom surface of the mounting member 2 , and mounting holes 23 are symmetrically provided on the mounting plate 22 , so that the mounting member 2 can be mounted on the outer side of the railway track through the mounting holes 23 on the mounting plate 22 .

[0030] like Figure 2 and Figure 5 As shown, a reset plate 32 is provided on the rod end of the reinforcing rod 31 extending to the outside of the reinforcing member 3, and the reset plate 32 is adapted to the receiving hole 21, so that the reinforcing member 3, the reinforcing rod 31 and the reset plate 32 are received inside the receiving hole 21, and at the same time, the reinforcing member 3, the reinforcing rod 31 and the reset plate 32 are locked inside the receiving hole 21 through the cooperation of the pulling plate 6 and the pulling spring 61.

[0031] like Figure 2 and Figure 5 As shown, a reinforcing plate 33 is provided on the reset plate 32 , and a reinforcing hole 34 is provided on the reinforcing plate 33 , so that the reinforcing rod 31 on the reset plate 32 is installed on the outer side of the mounting member 2 through the reinforcing hole 34 on the reinforcing plate 33 .

[0032] like Figure 2 and Figure 4 As shown, a connecting plate 42 is provided on the rod end of the connecting rod 41 extending to the outside of the connecting member 4 , and the connecting plate 42 is connected to the protective plate 1 , so that the connection stability between the connecting rod 41 and the protective plate 1 is improved through the connecting plate 42 .

[0033] Working principle: When the protective plate 1 is impacted, the protective plate 1 will drive the connecting rod 41 connected to the connecting plate 42 to move in the impact direction under the action of the impact force. At this time, the connecting rod 41 will drive the connecting member 4 to rotate on the buffer seat 7 in the impact direction. At the same time, the connecting rod 41 will slide in the direction away from the connecting member 4, thereby driving the buffer plate 71 to squeeze the buffer spring 72, and then the impact force on the protective plate 1 is buffered by the elasticity of the buffer spring 72. At the same time, the protective plate 1 will also drive the mounting member 2 to move in the impact direction under the action of the impact force. At this time, the mounting member 2 will drive the reinforcing member 3 to move away from The reinforcing rod 31 slides in the direction of the pulling plate 6, thereby driving the pulling plate 6 to squeeze the pulling spring 61, and then the impact force on the protective plate 1 is further buffered by the elasticity of the pulling spring 61. When the protective plate 1 is damaged due to excessive impact force, the connecting plate 42 loses the tensile force of the protective plate 1, so that the buffer plate 71 connected to the connecting rod 41 slides in the direction of the trigger switch 5 under the elastic force of the buffer spring 72. When the buffer plate 71 hits the trigger switch 5, the information of the damaged protective plate 1 can be transmitted to the background, and the staff can be automatically notified to repair the damaged protective plate 1.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
