AI Technical Summary
Existing highway bridge guardrails are fixed structures, which cannot effectively absorb the kinetic energy of vehicle collisions, resulting in vehicles being subjected to greater impacts and making them prone to dangerous situations such as rollovers, detachment from the road surface, and injuries to people.
An anti-collision telescopic device was designed, comprising a support frame, a sliding seat, an upright, and a thrust rod. By utilizing the sliding sealing fit between the sliding seat and the strip frame and the elastic support of the elastic element, the device achieves buffering and energy absorption of the vehicle through the movement of the upright and the support of the thrust rod.
It effectively absorbs the kinetic energy of a vehicle collision, reducing the impact on vehicles and people, improving safety, and lowering the risk of accidents.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of highway bridges, and particularly relates to an anti-collision telescopic device for highway bridges. Background Art
[0002] The anti-collision guardrails on highway bridges are mainly used to protect the bridge structure and the vehicles in motion, preventing the vehicles from rushing out of the road or hitting the bridge structure in case of an accident. They are generally set on both sides of the bridge, especially in areas with large traffic flow or accident-prone areas of the bridge.
[0003] However, most of the existing highway bridge guardrails are of fixed structures and cannot absorb kinetic energy by their own deformation. During a collision, almost all the kinetic energy of the vehicle is directly transmitted to the guardrail and the vehicle itself. This direct transmission will cause the vehicle to be greatly impacted, and it is easy to occur dangerous situations such as rollover, leaving the road surface, and personnel injury.

[0022] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described in detail below. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.
[0023] First embodiment:
[0024] Referring to Figs. 1-2As shown, this utility model provides an anti-collision telescopic device for highway bridges, including a support frame 1. The bottom of the support frame 1 is fixed to the ground through a base 101. The fixed installation of the base 101 to the ground forms a support for the support frame 1. Preferably, the base 101 has an inverted "T" shaped structure and is welded to the support frame 1 to achieve the fixation of the support frame 1.
[0025] Furthermore, the support frame 1 includes two horizontally arranged transverse extension rods, which are arranged vertically. Corresponding strip frames 2 are installed on the surfaces of the upper and lower transverse extension rods. The strip frames 2 on the two transverse extension rods correspond to each other. The strip frames 2 are slidably connected to the inside of the strip frames 2. The sliding seats 5 are slidably sealed with the inner wall of the strip frames 2. Preferably, an elastic element 4 is provided between the inner wall of the strip frames 2 and the sliding seat 5. The elastic element 4 is elastic and can form an elastic support for the sliding seat 5.
[0026] It also includes a vertical pole 3, with two sliding seats 5 respectively installed at its upper and lower ends, and a thrust rod 302 rotatably connected to the sliding seats 5. The thrust rod 302 can support the vertical pole 3. When a vehicle collides with the vertical pole 3, the thrust rod 302 pushes the sliding seat 5 to slide inside the strip frame 2. Since the sliding seat 5 and the strip frame 2 are in a sliding and sealed fit, buffering can be achieved. The movement of the sliding seat 5 can cause the vertical pole 3 to move backward and buffer. Furthermore, the elastic element 4 is a spring. The spring between the strip frame 2 and the sliding seat 5 provides elastic support for the sliding seat 5 and absorbs some of the kinetic energy using its elasticity.
[0027] The second embodiment differs from the first embodiment in that:
[0028] There are multiple strip frames 2, and the strip frames 2 are evenly distributed along the length direction of the transverse extension rod in the support frame 1. The uprights 3 are located between two strip frames 2, and multiple uprights 3 can achieve buffering of the vehicle with good buffering effect. Furthermore, the support frame 1 is in the shape of "I" or "mouth".
[0029] In a preferred embodiment, a protective rubber sleeve 301 is provided on the outer side of the upright 3. The protective rubber sleeve 301 is rotatably engaged with the upright 3. The protective rubber sleeve 301 is made of rubber and its outer wall is arc-shaped. The middle section of the arc is far away from the upright 3. The protective rubber sleeve 301 can form a buffer when the car initially hits the upright 3. Furthermore, the upper and lower ends of the upright 3 are rotatably connected to the sliding seat 5 through two thrust rods 302, so the thrust rods 302 provide better support for the upright 3. When the device is installed on a highway bridge, it can play a buffering role for vehicles.
[0030] In addition, the support frame 1 is provided with a horizontally extending stop rod between the upper and lower transversely extending rods, so that the support frame 1 has three horizontally extending rod portions. After the vehicle collides with and damages the vertical rod 3, the three rod-shaped structures on the support frame 1 are used to limit the vehicle, thereby achieving secondary blocking of the vehicle and achieving good blocking effect on the vehicle. The base 101 has an inverted "T" shape, and the base 101 is welded to the support frame 1.
[0031] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
