The "connection" and "coupling" involved in the present application, unless otherwise specified, include direct and indirect connections.

[0025] Unless otherwise specified, the components, sensors and other devices involved in the following embodiments are all conventional commercially available products.

[0026] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] This example discloses a tunnel anti-slip device, see Figure 1-4 , including an anti-collision beam 4, which is made of a square steel pipe. The pipe segment 12 is the main assembly component of the shield construction. The tunnel anti-slip device also includes a connection assembly fixed at the corresponding positions on both sides of the rail 22 at the bottom of the tunnel pipe segment 12. In this embodiment, the connection assembly includes four groups of expansion bolts 17 driven on the pipe segment 12 and a connecting plate 18 horizontally fixed on the expansion bolts 17. The four groups of expansion bolts 17 are symmetrically driven on the inner wall of the pipe segment 12 along the rail 22. The four groups of expansion bolts 17 are symmetrically driven on the inner wall of the pipe segment 12 along the rail 22. The expansion bolts 17 are arranged perpendicular to the horizontal plane. A plurality of expansion bolts 17 are fixed at the bottom of a connecting plate 18, and the support assembly is detachably connected to the upper end of the connecting plate 18.

[0028] The support assembly for supporting the anti-collision beam 4 is connected to the connection assembly correspondingly. The support assembly includes a left support 1, a right support 2 and two diagonal braces 3. The diagonal braces 3 for supporting the left support 1 and the right support 2 are connected to the left support 1 and the right support 2 respectively. The two diagonal braces 3 are fixed between the left support 1 and the right support 2 to form a stable triangular structure. At the same time, they can be used as a force transmission device after the vehicle slips, which is more stable, reliable and secure. The front end of the right support 2 is fixedly connected with a support plate 9 for placing the anti-collision beam 4. The support plate 9 is set horizontally. The support plate 9 is used to support the anti-collision beam 4 so that the anti-collision beam 4 can remain horizontal when the winch 7 releases the steel rope. The level of the anti-collision beam 4 can better resist the vehicle from slipping.

[0029] The alarm component is used to remind the driver of the position status of the anti-collision beam 4. The alarm component includes a light strip 14, two warning lights 15 and a sensor 16. The light strip 14 is wound around the side wall of the anti-collision beam 4. The light strip 14 is normally open to display the status of the anti-collision beam 4. The two warning lights 15 are respectively arranged on both sides of the anti-collision beam along the axial direction of the tunnel. Both warning lights 15 are 100m away from the anti-collision beam 4. The sensor 16 is fixedly connected to the left side wall of the left support 1. The sensor 16 is used to measure the position of the anti-collision beam 4. The sensor 16 is wired to the warning light 15 and the winch 7. When the anti-collision beam 4 is opened, when the sensor 16 senses the anti-collision beam 4, the sensor 16 controls the winch 7 to stop working and controls the warning light 15 to stop working. When the anti-collision beam 4 is closed, when the sensor 16 cannot sense the anti-collision beam 4, the sensor 16 controls the warning light 15 to start working.

[0030] The tunnel anti-slip device also includes a winch 7 fixed at a corresponding position on the inner wall of the tunnel segment 12 for driving the anti-collision beam 4 to rotate. A buckle 6 is fixedly connected to the upper end of the anti-collision beam 4. The buckle 6 facilitates the staff to fix the steel rope in the winch 7 to the anti-collision beam 4, and then the winch 7 drives the anti-collision beam 4 to rotate by retracting and releasing the steel rope.

[0031] The left end of the left support 1 is fixedly connected with a side plate 8, and the anti-collision beam 4 is hinged with the side plate 8. A reserved groove 10 is provided at the left end of the anti-collision beam 4. When the anti-collision beam 4 rotates to a vertical state, the side plate 8 will be placed in the reserved groove 10 and will not affect the rotation of the anti-collision beam 4. A support rod 13 is fixedly connected to the left side of the side plate 8. One end of the support rod 13 away from the side plate 8 is fixedly connected to the inner wall of the pipe sheet 12. The support rod 13, the side plate 8 and the pipe sheet 12 form a triangular structure to improve the deformation resistance of the side plate 8 and prevent the side plate 8 from deforming after long-term use and affecting the rotation of the anti-collision beam 4.

[0032] The bottom ends of the left support 1, the right support 2 and the diagonal brace 3 are all fixed with a steel plate 19, and the steel plate 19 is fixedly connected to the connecting plate 18 by bolts.

[0033] The tunnel anti-slip device also includes a wired controller 20 and a wireless controller 21 for correspondingly controlling the winch 7. The winch 7 is started and stopped by the wired controller 20 and the wireless controller 21, and the wireless controller 21 is carried and used by the driver.

[0034] Working principle: First, when the anti-slip device is turned on, the winch 7 releases the steel rope, and the anti-collision beam 4 is supported by the support plate 9 to maintain a horizontal state. At this time, the sensor 16 cannot sense the anti-collision beam 4, so both warning lights 15 remain on. When the car is ready to pass, the winch 7 retracts the steel rope, and the winch 7 pulls the anti-collision beam 4 to start rotating counterclockwise. When the anti-collision beam 4 is vertical, the sensor 16 detects the anti-collision beam 4, and the sensor 16 will control the winch 7 to stop working. At the same time, the sensor 16 controls the warning light 15 to stop working to remind the driver that the anti-slip device is closed and the car can pass.

[0035] After the driver passes, the driver can control the winch 7 to release the steel rope. The anti-collision beam 4 is affected by gravity and starts to rotate clockwise. The sensor 16 cannot sense the anti-collision beam 4, and the alarm light 15 starts working again until the anti-collision beam 4 contacts the support plate 9, and the winch 7 stops working. At this time, the anti-skid device is in the on state.

[0036] At the same time, a pedestrian walkway is usually set up in the tunnel, and the pedestrian walkway is generally equipped with guardrails. The position of the winch 7 fixed on the inner wall of the pipe segment 12 needs to be guaranteed, the steel rope connected between the winch 7 and the buckle 6 will not touch the guardrail, and the winch 7 needs to be kept on the same side as the hinge between the anti-collision beam 4 and the side plate 8, and the pedestrian walkway will not affect the rotation of the anti-collision beam 4. The winch 7 can also be controlled by a wired controller 20 placed on the pedestrian walkway.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.
