Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of road protection, and particularly relates to a buffer guardrail. Background Art
[0002] In the modern traffic system, as an important infrastructure, bridge roads carry a huge traffic flow and transportation pressure. However, due to factors such as high vehicle speeds, driver operation errors, and unforeseen emergencies, traffic accidents occur frequently. Traditional bridge road guardrails mostly adopt rigid structures, such as concrete guardrails or metal guardrails. Although these guardrails can play a certain role in blocking and protection, when a vehicle collides at high speed, they cannot effectively absorb and buffer the collision energy, easily resulting in serious damage to the vehicle. Therefore, at present, buffer plates for absorbing the impact potential energy of vehicles are installed on both sides of the guardrail. However, in actual applications, after the vehicle hits the buffer plate, the buffer plate buffers a part of the acting force and then applies the buffered acting force to the railing. At this time, the railing will deform to a certain extent. To ensure normal subsequent use, the staff needs to replace the railing. However, at present, the replacement of the railing is not only complicated in operation, but also the buffer plate is not easily damaged or the degree of damage after transmitting the acting force to the railing, resulting in an increase in the maintenance cost of the railing when the staff directly replaces the entire railing. Content of the Utility Model

A blocking block slides on the top of the splicing frame. Buffer plates are arranged on both sides of the fixed frame. Connecting positioning blocks are fixedly connected to both sides of the reinforcing rods. Mounting blocks are fixedly connected to both sides of the connecting positioning blocks. Connecting seats are fixedly connected to the sides of the connecting positioning blocks and the buffer plates corresponding to each other. The buffer pneumatic rods are located between the buffer plates and the connecting positioning blocks. Adaptor blocks are fixedly connected to both sides of the buffer pneumatic rods, and the adaptor blocks are screwed to the connecting seats.
[0005] Wherein, a positioning rod is fixedly connected to one side of the fixed frame, and an extension block is fixedly connected to the bottom end of the extension rod. The extension block slides inside the positioning rod.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Please refer to Figures 1 - 5, the present utility model provides the following technical solutions: It includes a fixed frame 1 and a buffer pneumatic rod 5. A number of reinforcing rods 11 are fixedly connected to the inner side of the fixed frame 1. A splicing frame 2 is fixedly connected to one side of the fixed frame 1, and an extension rod 21 is fixedly connected to the other side of the fixed frame 1. A blocking block 22 slides on the top of the splicing frame 2. Buffer plates 3 are provided on both sides of the fixed frame 1. Connecting positioning blocks 4 are fixedly connected to both sides of the reinforcing rod 11. Mounting blocks 41 are fixedly connected to both sides of the connecting positioning block 4. Connecting seats 42 are fixedly connected to the sides of the connecting positioning block 4 and the buffer plate 3 that correspond to each other. The buffer pneumatic rod 5 is located between the buffer plate 3 and the connecting positioning block 4. Adaptor blocks 51 are fixedly connected to both sides of the buffer pneumatic rod 5, and the adaptor blocks 51 are screwed to the connecting seats 42.
[0018] In this implementation plan: The fixed frame 1 is used to support and connect various components, so as to complete the buffering work during vehicle impact through the cooperation of other components. A number of reinforcing rods 11 are fixed inside the fixed frame 1. The reinforcing rods 11 are used to strengthen the overall structural strength of the fixed frame 1, so that the fixed frame 1 can be fixed in a suitable position to complete the work of blocking and guiding the road. A splicing frame 2 is fixed on one side of the fixed frame 1, and an extension rod 21 is fixed on the other side of the fixed frame 1. The staff can place a number of fixed frames 1 close to each other, and then slide the extension rod 21 fixed on one side of the fixed frame 1 into the splicing frame 2 fixed on one side of the adjacent fixed frame 1, so that the two adjacent fixed frames 1 can be connected and fixed. A blocking block 22 slides on the top of the splicing frame 2. The staff can fix the blocking block 22 to the fixed frame 1 through bolts, so that the blocking block 22 limits and restricts the extension rod 21, so that the two adjacent fixed frames 1 can be connected and fixed. When the impact causes damage to the fixed frame 1 or the reinforcing rod 11 and they cannot be used, the staff can slide the extension rod 21 out of the splicing frame 2 and slide the extension rod 21 fixed on one side of the new fixed frame 1 into the splicing frame 2 again, so as to quickly complete the installation and fixation work between the adjacent fixed frames 1, thereby improving the operation efficiency of the staff. Buffer plates 3 are provided on both sides of the fixed frame 1. The buffer plates 3 are used to buffer when the vehicle collides, to avoid greater damage to the vehicle. Connecting positioning blocks 4 are fixed on both sides of the reinforcing rod 11. The connecting positioning blocks 4 are used to connect and fix the buffer plates 3 to the reinforcing rod 11. An installation block 41 is fixed on one side of the connecting positioning block 4. The staff can connect and fix the installation block 41 to the reinforcing rod 11, so that the connecting positioning block 4 is installed and fixed on the outside of the reinforcing rod 11. A connecting seat 42 is fixed on one side of the connecting positioning block 4. A connecting seat 42 is also fixed on the side of the buffer plate 3 facing the reinforcing rod 11. A buffer pneumatic rod 5 is provided between the buffer plate 3 and the connecting positioning block 4. And fitting blocks 51 are fixed on both sides of the buffer pneumatic rod 5. The staff can rotate the fitting blocks 51 into the connecting seat 42 and thread the fitting blocks 51 with the connecting seat 42, so as to complete the installation and fixation of the buffer plate 3, and make the buffer pneumatic rod 5 located between the buffer plate 3 and the reinforcing rod 11. When the vehicle collides, the buffer plate 3 will be first subjected to a force, and then the buffer plate 3 will move towards the reinforcing rod 11. At this time, the buffer pneumatic rod 5 between the buffer plate 3 and the reinforcing rod 11 will be compressed and buffer the impact force. After part of the impact force is buffered, the remaining impact force will be applied to the reinforcing rod 11. When the impact force is too large and the buffer plate 3 or the connecting positioning block 4 is damaged, the staff can disassemble the buffer plate 3 or the connecting positioning block 4 from the buffer pneumatic rod 5, and then replace the buffer plate 3 or the connecting positioning block 4. When the fixed frame 1 and the reinforcing rod 11 are damaged, the staff can replace the fixed frame 1 and the reinforcing rod 11 according to the above steps.So that the staff can replace a certain component according to the actual situation, so as to achieve the purpose of saving the subsequent replacement and maintenance costs.
[0019] One side of the fixed frame 1 is fixedly connected with an alignment rod 23. The bottom end of the extension rod 21 is fixedly connected with an extension block 24, and the extension block 24 slides inside the alignment rod 23. The alignment rod 23 fixed on one side of the fixed frame 1 is used to further reinforce the connection between the splicing frame 2 and the extension rod 21. The bottom end of the extension rod 21 is fixed with an extension block 24. When the extension rod 21 slides into the splicing frame 2, the extension block 24 will slide into the alignment rod 23, making the connection between the splicing frame 2 and the extension rod 21 more stable, ensuring the connection reliability between adjacent fixed frames 1, and enabling several fixed frames 1 to stably complete the work of separating and guiding the road.
[0020] The bottom end of the blocking block 22 is fixedly connected with a limiting block 25, and the blocking block 22 is slidably connected to the top end of the splicing frame 2 through the limiting block 25. The limiting block 25 fixed at the bottom end of the blocking block 22 is used to connect the blocking block 22 and the splicing frame 2, and can locate the position of the blocking block 22. So that when the staff slides the extension rod 21 into the splicing frame 2, the staff can locate the position of the blocking block 22 by sliding the limiting block 25 into the splicing frame 2. At this time, the position of the bolt hole reserved inside the blocking block 22 will correspond to the position of the bolt hole opened on one side of the fixed frame 1. Then the staff can fix the blocking block 22 to the fixed frame 1 through bolts, so that the extension rod 21 can continuously be located inside the splicing frame 2, and complete the work of connecting and fixing adjacent fixed frames 1.
[0021] One side of the connection positioning block 4 is fixedly connected with an auxiliary block 43. A guiding groove 12 is opened inside the reinforcing rod 11, and the auxiliary block 43 slides inside the guiding groove 12. A threaded block 44 is rotatably connected inside the mounting block 41, and the threaded block 44 rotates inside the reinforcing rod 11. The auxiliary block 43 fixed on one side of the connection positioning block 4 is used to locate the position of the connection positioning block 4. So that when the staff replaces the connection positioning block 4, the auxiliary block 43 can be slid into the guiding groove 12, making the position of the threaded block 44 correspond to the position of the threaded grooves pre-opened on both sides of the reinforcing rod 11 and adapted to the outer side of the threaded block 44. Then the staff can rotate the threaded block 44 into the connection positioning block 4 and the reinforcing rod 11, so that the position of the connection positioning block 4 is limited and fixed. Then the staff installs the buffer pneumatic rod 5 between the buffer plate 3 and the connection positioning block 4. When the buffer plate 3 is hit by a vehicle, the buffer pneumatic rod 5 can effectively buffer the impact.
[0022] Working principle and usage process of the utility model: Workers can place several fixing frames 1 at appropriate positions on the road, and then slide the extension rod 21 fixed to one side of the fixing frame 1 into the splicing frame 2 fixed to one side of the adjacent fixing frame 1, so that the adjacent two fixing frames 1 can be connected and fixed. Workers can fix the blocking block 22 to the fixing frame 1 through bolts, so that the blocking block 22 limits and constrains the extension rod 21, thereby enabling the adjacent two fixing frames 1 to be connected and fixed. Then, workers can slide several connection positioning blocks 4 to both sides of the strengthening rod 11, and then connect and fix the connection positioning blocks 4 and the strengthening rod 11 through the threaded blocks 44. Then, the workers need to rotate the two adapter blocks 51 fixed to both sides of the buffer pneumatic rod 5 into the connection seats 42 fixed to the side of the buffer plate 3 corresponding to the connection positioning block 4 respectively, thus completing the final installation. When the vehicle hits the buffer plate 3, the buffer plate 3 will receive a force and move towards the connection positioning block 4. At this time, the buffer pneumatic rod 5 between the buffer plate 3 and the connection positioning block 4 will buffer the impact force. The buffered force will act on the connection positioning block 4 and the strengthening rod 11. After the impact, the workers can replace a certain damaged component separately through the above steps, thereby achieving the purpose of saving subsequent replacement and maintenance costs.
