Description

Technical Field

[0001] This utility model relates to the field of road and bridge architectural design technology, specifically to a road and bridge guardrail support device. Background Technology

[0002] Guardrail support devices are an important component of road and bridge structures. Their main function is to provide stable and reliable support for the guardrails, ensuring that they can effectively fulfill their protective functions. The design of guardrail support devices needs to take into account a variety of factors, including road grade, traffic flow, vehicle type, and collision energy.

[0003] However, existing road and bridge guardrail support devices typically require workers to tightly connect the guardrail to the support frame using bolts to ensure its function. However, when used outdoors, heavy rain corrodes and rusts the bolts, causing them to loosen and reducing the stability of the support device. Furthermore, during use, pedestrians frequently collide with the guardrails, and over time, these impacts accumulate, potentially leading to loosening of the guardrails and further reducing the stability of the support device. Utility Model Content

A protective shell is movably connected to the surface of the bolt rod. A connecting plate is fixedly connected to one side of the protective shell. A guide rod is fixedly connected to the surface of the support frame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 As shown, a road bridge guardrail support device includes a base 1, with a support frame 2 fixedly connected to the top of the base 1. The base 1 and support frame 2 work together to support the device, enabling it to operate. A guardrail 3 is provided on one side of the support frame 2, protecting pedestrians and preventing them from falling off the bridge surface. A bolt 4 is threaded into the inner cavity of the guardrail 3, and its surface is threaded into the inner cavity of the support frame 2. The bolt 4 secures the guardrail 3 to one side of the support frame 2, allowing it to function. A protective shell 5 is movably connected to the surface of the bolt 4, protecting it and reducing the risk of rainwater erosion and loosening, thus improving the stability of the device. A connecting plate 6 is fixedly connected to one side of the protective shell 5, and a guide rod 7 is fixedly connected to the surface of the support frame 2. The guide rod 7 guides the connecting plate 6. A tension spring is fixedly connected to the surface of the support frame 2. Spring 8, the other end of tension spring 8 is fixedly connected to one side of connecting plate 6. Guide rod 7 is located at the center of tension spring 8, and the surface of guide rod 7 is slidably connected to the inner cavity of connecting plate 6. With the cooperation of connecting plate 6 and guide rod 7, tension spring 8 can be stretched on one side of support frame 2. A limit mechanism 9 is provided on one side of support frame 2. Under the action of limit mechanism 9, the protective shell 5 is effectively prevented from returning to its original position when the bolt rod 4 is installed, thus facilitating the installation and disassembly of bolt rod 4. A buffer plate 11 is installed on one side of protective rod 3, and a buffer mechanism 12 is provided on one side of buffer plate 11. With the cooperation of buffer plate 11 and buffer mechanism 12, personnel can be buffered in the event of a collision, reducing the impact of collision force on protective rod 3, thereby improving the stability of the device. Reflective strips 13 are installed on the surface of buffer plate 11. There are multiple reflective strips 13, which correspond to the number of buffer plates 11. With the action of reflective strips 13, the device can be seen by the staff at night.

[0023] The limiting mechanism 9 includes a fixed block 91. One side of the fixed block 91 is fixedly connected to the surface of the support frame 2. A rotating rod 92 is rotatably connected to one side of the fixed block 91. A limiting plate 93 is fixedly connected to the other end of the rotating rod 92. The surface of the limiting plate 93 is slidably connected to the surface of the connecting plate 6. Under the action of the fixed block 91, the rotating rod 92 can drive the limiting plate 93 to move on one side of the connecting plate 6, allowing the limiting plate 93 to limit the position of the connecting plate 6. This effectively prevents the protective shell 5 from returning to its original position due to the rebound of the tension spring 8 when the bolt rod 4 is installed and disassembled, thereby improving the practicality of the device. A corresponding groove 10 is opened on the surface of the connecting plate 6. The inner cavity of the corresponding groove 10 is slidably connected to the surface of the limiting plate 93. Under the action of the corresponding groove 10, the limiting plate 93 is effectively prevented from detaching from one side of the connecting plate 6 during operation, thereby improving the stability of the device.

[0024] The buffer mechanism 12 includes a sliding rod 121. One end of the sliding rod 121 is fixedly connected to one side of the buffer plate 11, and the surface of the sliding rod 121 is slidably connected to the inner cavity of the protective rod 3. A shock-absorbing spring 122 is fixedly connected to one side of the buffer plate 11, and the other side of the shock-absorbing spring 122 is fixedly connected to one side of the protective rod 3. A limit block 123 is fixedly connected to the other end of the sliding rod 121. Under the action of the buffer plate 11, the sliding rod 121 can move within the inner cavity of the protective rod 3, and the shock-absorbing spring 122 can be compressed on one side of the protective rod 3. This effectively reduces the impact of collision forces from passing personnel on the protective rod 3, thereby improving the practicality of the device. Under the action of the limit block 123, the sliding rod 121 is effectively prevented from detaching from the interior of the protective rod 3.

[0025] Working principle: First, the operator uses the foot base 1 to fix the support frame 2 in the corresponding working position. When the operator needs to install the protective rod 3 on the surface of the support frame 2 using the bolt rod 4, the tension spring 8 can be stretched on one side of the support frame 2 with the cooperation of the connecting plate 6 and the guide rod 7. This allows the protective shell 5 to move away from the support frame 2 along with the connecting plate 6. Subsequently, under the action of the fixing block 91, the rotating rod 92 can drive the limiting plate 93 to move towards the connecting plate 6, so that the surface of the limiting plate 93 corresponds to the inner cavity of the corresponding groove 10, enabling the limiting plate 93 to align with the connecting plate 6. The device is positioned so that the worker can install the guard rod 3 on one side of the support frame 2. When a passerby accidentally bumps into the buffer plate 11, the buffer plate 11 can move the sliding rod 121 within the cavity of the guard rod 3, and the shock-absorbing spring 122 can be compressed on the surface of the guard rod 3, so that the buffer plate 11 can buffer the impact force. When the passerby separates from the buffer plate 11, the shock-absorbing spring 122 can return the buffer plate 11 to its original position under the action of the rebound. Under the action of the limiting block 123, the sliding rod 121 is prevented from leaving the interior of the guard rod 3. Then the worker can install other devices.
