[0028] The following further describes in detail the embodiments of the present invention with reference to the drawings and examples. The following examples are used to illustrate the present invention but cannot be used to limit the scope of the present invention.

[0029] Embodiment 1

[0030] As shown in the attached Figure 1As shown in the figure, the present invention provides an assembled highway bridge anti-collision device for construction, including a vertical rod 1, where the vertical rod 1 is installed at the edge of the road. A plurality of vertical rods 1 are provided with receiving grooves 2, and a cross rod 3 is arranged in the receiving groove 2. The vertical rod 1 and the cross rod 3 cooperate to intercept the vehicle, preventing the vehicle from rushing out of the road or bridge. The receiving groove 2 is connected with a disassembly and assembly component 4, and the disassembly and assembly component 4 can be taken out of the receiving groove 2. After the disassembly and assembly component 4 is taken out of the receiving groove 2, the damaged cross rod 3 can be replaced at this time, and the maintenance cost and workload are reduced by means of partial replacement. When the disassembly and assembly component 4 is fixed in the receiving groove 2, the disassembly and assembly component 4 and the vertical rod 1 cooperate to limit the cross rod 3, preventing the cross rod 3 from shifting and ensuring the interception effect. A plurality of cross rods 3 are connected with a buffer component 5, and the buffer component 5 can absorb the energy generated by the collision, achieving a buffering effect. At the same time, the buffer component 5 can disperse the collision energy to the cross rod 3, avoiding the concentration of impact and improving the protection effect. The buffer component 5 is connected with an anti-collision plate 6, and the anti-collision plate 6 and the roller 7 are made of materials with elasticity and buffering performance, such as rubber, composite materials, etc. They can absorb part of the energy when being impacted, reducing the impact on the vehicle, the cross rod 3, and the vertical rod 1. The anti-collision plate 6 is rotatably connected with a plurality of rollers 7. When the vehicle impacts the anti-collision plate 6, the rollers 7 will rotate along the impact direction of the vehicle, thereby guiding the movement direction of the vehicle and avoiding hard collision between the vehicle and the anti-collision plate 6. At the top of a plurality of vertical rods 1, there is a warning component 8, and the warning component 8 actively emits sound and light alarms when the vehicle deviates from the lane or approaches the critical distance, transmitting warning information to the vehicle.

[0031] As can be seen from the above, when this device is installed in accident-prone areas such as sharp turns and steep slopes, the warning component 8 will actively emit sound and light alarms when the vehicle deviates from the lane or approaches the critical distance, transmitting warning information to the vehicle and reminding the vehicle to pay attention to the safety distance. When a vehicle hits this device, the vehicle contacts the anti-collision plate 6. The anti-collision plate 6 can absorb part of the energy when being impacted, reducing the impact on the vehicle, the cross rod 3, and the vertical rod 1. At the same time, the rollers 7 will rotate along the impact direction of the vehicle, thereby guiding the movement direction of the vehicle and avoiding hard collision between the vehicle and the anti-collision plate 6. The anti-collision plate 6 transmits the impact energy to the buffer component 5, and the buffer component 5 absorbs the energy generated by the collision, achieving a buffering effect. At the same time, the buffer component 5 disperses the collision energy to the cross rod 3, and the cross rod 3 and the vertical rod 1 jointly bear the impact, avoiding the concentration of impact force and improving the protection effect. If the impact force is large, the anti-collision plate 6, the buffer component 5, or the cross rod 3 can be disassembled according to the situation, and the maintenance cost and workload are reduced by means of partial replacement.

[0032] Embodiment 2

[0033] As shown in the appendix Figure 1 to the appendix Figure 4As shown, this embodiment is basically the same as the previous one, except that the buffer assembly 5 includes a base 501 connected to the cross bar 3. The base 501 is provided to facilitate the installation of the buffer assembly 5 on the cross bar 3. The base 501 is bolted with a first hinge seat 502, and the first hinge seat 502 is rotatably connected with a receiving cylinder 503. By providing the first hinge seat 502, the receiving cylinder 503 can be rotated, facilitating the receiving cylinder 503 to change its direction according to the impact, avoiding a hard collision between the vehicle and the cross bar 3. The receiving cylinder 503 is slidably connected with a piston rod 504. When the anti-collision plate 6 is impacted, the anti-collision plate 6 transmits the impact to the piston rod 504. At this time, the piston rod 504 moves into the receiving cylinder 503, and at the same time, the buffer spring 507 is compressed and absorbs kinetic energy. The two ends of the piston rod 504 are respectively fixedly connected with a piston plate 505 and a connecting plate 506. The anti-collision plate 6 transmits the impact to the piston rod 504 through the connecting plate 506. A buffer spring 507 is sleeved on the circumference of the piston rod 504. The piston plate 505 is provided with a number of through holes 508. The piston plate 505 slides in the receiving cylinder 503 following the piston rod 504. At this time, the hydraulic oil passes through the through holes 508 and flows from one side of the receiving cylinder 503 to the other side of the receiving cylinder 503. The connecting plate 506 is fixedly connected with a second hinge seat 509. The second hinge seat 509 and the first hinge seat 502 cooperate to rotate the receiving cylinder 503 and change the direction of the impact, avoiding a hard collision between the vehicle and the cross bar 3. To ensure the effect of the anti-collision plate 6 changing the impact direction, the anti-collision plate 6 is connected with at least two groups of buffer assemblies 5, and the two groups of buffer assemblies are in a "V" shape.

[0034] Specifically, one end of the piston rod 504 connected to the piston plate 505 extends into the receiving cylinder 503. The piston plate 505 is in contact with the inner wall of the receiving cylinder 503. When the piston rod 504 is stressed, it will drive the piston plate 505 to slide along the length direction of the receiving cylinder 503. The receiving cylinder 503 is filled with hydraulic oil. The hydraulic oil flows from one side of the receiving cylinder 503 to the other side through the through holes 508, which can inhibit the reciprocating movement of the buffer spring 507 and ensure the buffering effect.

[0035] Furthermore, one end of the buffer spring 507 is fixedly connected to the connecting plate 506, and the other end of the buffer spring 507 is fixedly connected to the receiving cylinder 503 to prevent the buffer spring 507 from falling off. The second hinge seat 509 is bolted to the anti-collision plate 6, facilitating the disassembly and replacement of the anti-collision plate 6.

[0036] It should be noted that there is an error in the original text where it says "the two groups of buffer assemblies are in a 'V' shape", it should be "the two groups of buffer assemblies are in an 'eight' shape". The above translation has been corrected accordingly.Further, the warning component 8 includes a single-chip microcomputer, which serves as the core control unit, responsible for receiving the signals from the radar sensor 801 and processing them. The single-chip microcomputer is connected to the radar sensor 801, the buzzer 802, and the LED light 803. The radar sensor 801 is used to monitor the driving trajectory of the vehicle and the distance from the lane line in real time. When the radar sensor 801 detects that the vehicle deviates from the lane or approaches the critical distance, the single-chip microcomputer controls the buzzer 802 and the LED light 803 to emit a sound alarm and a light alarm to remind the driver in the vehicle, thereby actively giving a warning to avoid the vehicle hitting this device.

[0037] Further, the single-chip microcomputer is arranged in the protective box 804, and the protective box 804 can provide protection for the single-chip microcomputer. The radar sensor 801, the buzzer 802, and the LED light 803 are arranged on the surface of the protective box 804, which can better collect information and give an alarm. The protective box 804 is fixedly arranged at the top of the vertical rod 1, and the top of the vertical rod 1 is higher than the height of the vehicle, which can protect the warning component 8.

[0038] As can be seen from the above, this device is installed in accident-prone areas such as sharp curves and steep slopes. The radar sensor 801 monitors the position of the vehicle and sends the information to the single-chip microcomputer for processing. When the radar sensor 801 detects that the vehicle deviates from the lane or approaches the critical distance, the single-chip microcomputer controls the buzzer 802 and the LED light 803 to emit a sound alarm and a light alarm to actively give a warning to remind the driver in the vehicle to avoid the vehicle hitting this device;

[0039] When a vehicle cannot avoid hitting this device in time, the vehicle contacts the anti-collision plate 6 and the roller 7. The roller 7 rotates to guide the movement direction of the vehicle, avoiding a hard collision between the vehicle and the anti-collision plate 6. The anti-collision plate 6 absorbs part of the energy, reducing the impact on the vehicle, the cross bar 3, and the vertical rod 1. At the same time, the anti-collision plate 6 transfers the impact energy to the piston rod 504 through the second hinge seat 509 and the connecting plate 506. At this time, the piston rod 504 drives the piston plate 505 to move in the receiving cylinder 503. At the same time, the buffer spring 507 is compressed by the connecting plate 506 and absorbs kinetic energy. During the movement of the piston plate 505, the hydraulic oil passes through the through hole 508 and flows from one side of the receiving cylinder 503 to the other side of the receiving cylinder 503, inhibiting the reciprocating movement of the buffer spring 507 and ensuring the buffering effect. At the same time, the buffer component 5 disperses the collision energy to the cross bar 3, and the cross bar 3 and the vertical rod 1 jointly bear the impact, avoiding the concentration of the impact force and improving the protection effect. When the anti-collision plate 6 is hit, the first hinge seat 502 and the second hinge seat 509 cause the receiving cylinder 503 to rotate due to the impact force, and at this time, the orientation of the anti-collision plate 6 changes, further changing the direction of the impact, thereby avoiding a hard collision between the vehicle and the cross bar 3.

[0040] Embodiment 3

[0041] As shown in the appendix Figure 3 、appendixFigure 5 and appendix Figure 6 As shown, this embodiment is basically the same as the previous one. The difference is that the disassembly and assembly component 4 includes a limiting block 401 movably connected to the receiving groove 2. When the conditions are met, the limiting block 401 can be removed from the receiving groove 2. The limiting block 401 is fixedly connected with a guiding block 402. The receiving groove 2 communicates with a guiding groove 403. Through the sliding fit between the guiding block 402 and the guiding groove 403, the limiting block 401 can be easily inserted into the receiving groove 2. The vertical rod 1 and the guiding block 402 are provided with a slot 404. A plug rod 405 is slidably connected to the slot 404. When the plug rod 405 is inserted into the deepest part of the slot 404, the positions of the guiding block 402 and the limiting block 401 are fixed. The plug rod 405 is sleeved with a limiting spring 406. Pulling the plug rod 405 out of the slot 404 can release the limitation on the guiding block 402 and the limiting block 401. At this time, the limiting spring 406 is compressed to store energy, preparing for the reset of the plug rod 405. The vertical rod 1 is fixedly connected with a shielding plate 407. The shielding plate 407 is slidably connected to the plug rod 405. The shielding plate 407 can provide protection and shielding for the limiting spring 406 and assist the stable sliding of the plug rod 405.

[0042] Specifically, after the limiting block 401 is inserted into the receiving groove 2, the unfilled area of the receiving groove 2 is adapted to the size of the cross bar 3. A fitting groove is formed on one side of the limiting block 401. The shape of the fitting groove is adapted to the cross bar 3. After the limiting block 401 is inserted into the receiving groove 2, the cross bar 3 is fixed between the limiting block 401 and the receiving groove 2 of the vertical rod 1.

[0043] Furthermore, the guiding block 402 is in sliding fit with the guiding groove 403. The plug rod 405 is a U-shaped rod. Two limiting springs 406 are respectively sleeved on the two side arms of the plug rod 405. One end of the limiting spring 406 is fixedly connected with the shielding plate 407, and the other end of the limiting spring 406 is fixedly connected with the vertical rod 1, preventing the limiting spring 406 from falling off.

[0044] Furthermore, a base plate 9 is fixedly connected to the lower surface of the vertical rod 1. The base plate 9 is movably connected with a threaded rod 10. The threaded rod 10 is embedded in the road. The threaded rod 10 is connected with a nut 11. Align the base plate 9 and insert it onto the threaded rod 10 to complete the preliminary installation. Then screw the nut 11 into the lower end of the threaded rod 10 to fix the vertical rod 1 at the edge of the road.

[0045] As described above, the substrate 9 is aligned and inserted onto the threaded rod 10 to complete the preliminary installation. Then, the nut 11 is screwed onto the lower end of the threaded rod 10, and the vertical rod 1 can be fixed at the edge of the road. The cross bar 3 is placed into the receiving groove 2. Then, the insertion rod 405 is pulled outwards to disengage the insertion rod 405 from the insertion slot 404. At this time, the limiting spring 406 is compressed to store energy. Then, the limiting block 401 is inserted into the receiving groove 2 through the cooperation of the guiding block 402 and the guiding groove 403. At this time, the cross bar 3 is fixed between the limiting block 401 and the receiving groove 2 of the vertical rod 1. Then, the insertion rod 405 is released. When the limiting spring 406 drives the insertion rod 405 to reset and insert into the deepest part of the insertion slot 404, the positions of the guiding block 402 and the limiting block 401 are fixed, and further the cross bar 3 is installed and fixed. As described above, the cross bar 3 can be disassembled by reverse operation;

[0046] If the impact force is large, according to the situation, the anti-collision plate 6, the buffer assembly 5, the cross bar 3 or the vertical rod 1 can be disassembled, and the maintenance cost and workload can be reduced by means of partial replacement.
