Description

Technical Field

[0001] The utility model relates to the technical field of tunnel fences, in particular to a tunnel traffic safety protection fence. Background Art

[0002] Tunnels are engineering structures buried in mountains. With the continuous development of society, in order to facilitate people's travel and reduce distance, tunnels are often opened in mountains and roads are built to allow vehicles to pass. Traffic tunnels are mainly composed of a tunnel body and a tunnel portal. At the entrance of a highway tunnel, the width of the roadbed before entering the tunnel is greater than the width of the roadbed inside the tunnel, forming a sudden change in width. In addition, the sudden change in light at the tunnel entrance makes it easy for vehicles to collide at the tunnel entrance. In order to improve the traffic environment, tunnel traffic safety protection fences will be installed on the side of the tunnel.

[0003] The patent document with announcement number CN217378562U discloses a safety guardrail for highway bridges and tunnels, including a mounting plate, one side of which is fixedly connected to a safety guardrail, and one side of which is provided with an adjustment component, and the adjustment component includes a high-reflective warning sign. The advantage of this utility model is that when the safety guardrail needs to be used inside a tunnel, first, the mounting plate needs to be fixed to the edge of the tunnel through the mounting hole, the fixing column is pulled to move it out of the fixing hole, the adjustment plate is rotated to place the high-reflective warning sign on the outside, and the fixing column is loosened to move it into the fixing hole under the action of a spring, so that the safety guardrail can be used inside the tunnel. When using the guardrail on a bridge, the safety guardrail is installed through the mounting hole, and then the fixing column is pulled and the adjustment plate is adjusted until the low-reflective warning sign is on the outside. It can not only play a protective role, but also prevent light pollution. However, the existing technology still has defects:

[0004] The existing tunnel safety guardrail has a single function and poor anti-collision effect. When a vehicle collides with the safety guardrail, the safety guardrail as a whole is prone to deformation when subjected to force due to its poor buffering and shock absorption capabilities, which can easily cause huge damage to the vehicle and the driver and passengers, reducing the practicality of the safety guardrail.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0010] Anti-collision rollers, which are arranged between the two end cross bars, and there are several anti-collision rollers arranged at equal intervals;

[0011] A buffer structure is provided at both ends of the anti-collision roller. The buffer structure includes grooves opened on the opposite side of the cross bars at both ends. The two ends of the inner wall of the groove are fixedly connected with guide rods, and a slider is slidably connected to the guide rod. A damping shock-absorbing rod is fixedly connected between the rear end of the inner wall of the groove and the slider.

[0015] Furthermore, the bottom of the column is fixedly connected to a base, and four corners of the base are provided with mounting holes.

[0016] The advantages of the present invention compared with the prior art are: through the arrangement of the anti-collision roller and the buffer structure, when a traffic accident occurs, the vehicle first collides with the anti-collision roller, and the anti-collision roller can rotate circumferentially around the axial direction of the rotating shaft, thereby decomposing the huge impact force, and the buffer rubber in the anti-collision roller undergoes elastic deformation under the action of external force, thereby absorbing the kinetic energy during the collision, and at the same time, the anti-collision roller drives the slider to slide on the guide rod, and squeezes the damping shock-absorbing rod and the buffer spring, which can play a role of buffering and shock-absorbing, and absorb the impact force during the collision, so that the protective fence can first buffer the impact force and then rebound when it is hit, achieving a double anti-collision effect, thereby reducing the rigid collision between the vehicle and the protective fence, thereby reducing the possibility of serious damage to the vehicle and the driver and passengers, and improving the practicality of the tunnel traffic safety protective fence.

[0024] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0025] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 5As shown, this embodiment proposes a method including a column 1, two columns 1 are symmetrically arranged, a cross bar 2 is provided between the columns 1 at both ends, and there are two cross bars 2 and symmetrically arranged. The bottom of the column 1 is fixedly connected to a base 7, and the four corners of the base 7 are provided with mounting holes 8. When used inside the tunnel, the base 7 is fixed to the edge of the tunnel through the mounting holes 8, which can effectively separate the activity space of pedestrians and vehicles, completely separate the flow of people and vehicles, and allow them to go their own way without interfering with each other, thereby reducing the occurrence of personal injury accidents.

[0027] Anti-collision rollers 3 are provided between the cross bars 2 at both ends. There are several anti-collision rollers 3 arranged at equal intervals. A rotating shaft 31 is fixedly connected to both ends of the anti-collision roller 3. The rotating shaft 31 is rotatably connected to the opposite side of the slider 43. Buffer rubber is provided in the anti-collision roller 3. The setting of the rotating shaft 31 can make the anti-collision roller 3 rotate circumferentially around the axial direction of the rotating shaft 31 when the vehicle collides with the anti-collision roller 3, thereby decomposing the huge impact force. The buffer rubber in the anti-collision roller 3 will undergo elastic deformation when subjected to external force, thereby absorbing the kinetic energy during the collision.

[0028] A buffer structure 4 is provided at both ends of the anti-collision roller 3. The buffer structure 4 includes grooves 41 opened on the opposite side of the cross bars 2 at both ends. Guide rods 42 are fixedly connected to the two ends of the inner wall of the groove 41. A slider 43 is slidably connected to the guide rod 42. A damping shock-absorbing rod 44 is fixedly connected between the rear end of the inner wall of the groove 41 and the slider 43. The damping shock-absorbing rod 44 is arranged between the guide rods 42 at both ends. A buffer spring 45 is provided on the outer side of the damping shock-absorbing rod 44. When the anti-collision roller 3 is hit, the slider 43 is driven to slide on the guide rod 42 and squeeze the damping shock-absorbing rod 44 and the buffer spring 45. The damping shock-absorbing rod 44 and the buffer spring 45 can play a role of buffering and shock absorption and absorb the impact force during collision.

[0029] A high-reflective warning sign 6 is fixedly connected to the surface of one end of the crossbar 2. There are several high-reflective warning signs 6 that are arranged at equal intervals. The high-reflective warning sign 6 is set at the upper end of the column 1. The high-reflective warning sign 6 can serve as a warning to the driver, thereby reducing the possibility of the driver colliding with the protective fence when driving in the tunnel.

[0030] like Figure 6 As shown, as a preferred embodiment, on the basis of the above method, a rubber membrane 5 is further fixedly connected between the slider 43 and the upper end of the inner wall of the groove 41, and the rubber membrane 5 is arranged at both ends of the slider 43, wherein the rubber membrane 5 is a closed elastic membrane. The groove 41 can be shielded by the setting of the rubber membrane 5, so that when the protective fence is not collided, the damping shock absorbing rod 44 and the buffer spring 45 inside the groove 41 will not be covered with too much dust and other impurities, avoiding affecting the buffering and shock absorbing effect of the damping shock absorbing rod 44 and the buffer spring 45, and the rubber membrane 5 can be elastically stretched and dust-proof without hindering the movement of the slider 43.

[0031] During the specific implementation of the present invention, the base 7 is first fixed to the edge of the tunnel through the mounting hole 8. The highly reflective warning sign 6 can serve as a warning to the driver, thereby reducing the possibility of the driver colliding with the protective fence when driving in the tunnel. When a vehicle is involved in a traffic accident, the vehicle first collides with the anti-collision roller 3. The anti-collision roller 3 can rotate circumferentially around the axial direction of the rotating shaft 31, thereby decomposing the huge impact force. The buffer rubber in the anti-collision roller 3 is elastically deformed by the external force, thereby absorbing the kinetic energy of the collision. At the same time, the anti-collision roller 3 drives the slider 43 to slide on the guide rod 42 and squeezes the damping shock-absorbing rod 44 and the buffer spring 45. The damping shock-absorbing rod 44 and the buffer spring 45 can play a role in buffering and shock-absorbing, and absorb the impact force during the collision, so that when the protective fence is hit during use, it can first buffer the impact force and then rebound, achieving a double anti-collision effect, thereby reducing the rigid collision between the vehicle and the protective fence, thereby reducing the possibility of serious damage to the vehicle and the driver and passengers, and improving the practicality of the tunnel traffic safety protective fence.
