Description

Technical Field

[0001] This utility model belongs to the field of highway engineering technology, and in particular relates to an emergency collision avoidance device for highway engineering. Background Technology

[0002] During highway construction, warning signs and other early warning devices need to be erected before and after the construction site, and crash barriers, crash barrels, or other crash prevention equipment need to be set up to prevent vehicles from entering the construction site, in order to ensure the safety of the construction site. A search revealed that patent application number 202321140887.5 discloses an early warning device and emergency crash prevention equipment for highway engineering, including a base plate. An energy-absorbing cover is fixedly installed on the top of the base plate, and a fixed column is installed on the top of the base plate. An energy-absorbing cylinder is set on the outside of the fixed column, and the energy-absorbing cylinder is fixed to the base plate by bolts. Multiple energy-absorbing components are arranged on the inner wall of the energy-absorbing cover. Each energy-absorbing component includes an arc-shaped plate welded to the inner wall of the energy-absorbing cover. An installation sleeve is set inside the arc-shaped plate, and a crash prevention plate is welded into the inner cavity of the installation sleeve. The crash prevention plate is M-shaped. A fog light is installed on the top of the energy-absorbing cover, and a warning light is fixedly installed on one side of the fog light by bolts. An alarm is fixedly installed on the other side of the warning light by bolts.

[0003] However, in actual use, the applicant found that simply setting the fixed posts and base plate of the crash barrier to concrete material, although it can provide better protection for vehicles, the crash barrier is relatively light and is prone to moving and tilting after being hit by a vehicle, thus reducing the crash protection effect. In view of this, we propose an emergency crash barrier for highway engineering. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to an emergency collision avoidance device for highway engineering, comprising a base, a baffle fixedly connected to the top of the base, a collision avoidance plate provided on the front side of the baffle, a buffer pad fixedly connected to the front side of the collision avoidance plate, a reflective strip fixedly connected to the front side of the buffer pad, guide rods fixedly installed at the four corners of the rear side of the collision avoidance plate, the guide rods movably penetrating the baffle, a boat-shaped buffer bracket fixedly connected to the front side of the baffle by bolts, a warning sign fixedly connected to the top of the baffle by a support rod, a strip warning light fixedly connected to the support rod below the warning sign, a column fixedly connected to the top of the base on the rear side of the baffle, a concrete pressure block sleeved on the column, and an anti-slip pad fixedly connected to the bottom of the base.

[0006] Preferably, two columns are arranged side by side at the top of the base, and the concrete block is provided with a through hole, through which the concrete block is fitted onto the outside of the column.

[0007] Preferably, the concrete block is placed on top of the base, and the concrete block has symmetrical grooves on both sides.

[0008] Preferably, a limiting part is fixedly provided at the rear end of the guide rod.

[0009] Preferably, there are two boat-shaped buffer brackets on the front side of the baffle, one above the other, and the middle part of the boat-shaped buffer brackets is fixedly connected to the baffle by bolts.

[0010] Preferably, both ends of the boat-shaped buffer bracket are rotatably connected to rollers via axles, and the rollers are in contact with the rear sidewall of the anti-collision plate.

[0011] This utility model has the following beneficial effects:

[0012] This utility model discloses an emergency collision avoidance device for highway engineering. Through reflective strips, strip warning lights, and warning signs, it can warn vehicles and remind drivers to avoid collisions. When a vehicle impacts the buffer pad, the deformation of the buffer pad provides initial cushioning. Then, as the buffer pad moves the crash barrier along the guide rod backward, it compresses the boat-shaped buffer support, causing it to expand outward and deform, thus providing secondary cushioning protection for the vehicle and further improving the collision avoidance effect. By placing concrete blocks at the bottom of the base and installing anti-slip pads at the bottom of the base, the collision avoidance device is more stable, preventing it from easily shifting or tipping over after a vehicle impact. Compared to using concrete crash barriers, it provides better protection for vehicles and eliminates the need to fix the device in the ground by driving in ground spikes, reducing damage to the ground.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] An emergency collision avoidance device for highway engineering includes a base 1, a baffle 2 fixedly connected to the top of the base 1, a collision avoidance plate 3 provided on the front side of the baffle 2, a buffer pad 4 fixedly connected to the front side of the collision avoidance plate 3, a reflective strip 5 fixedly fixed on the front side of the buffer pad 4, guide rods 31 fixedly provided at the four corners of the rear side of the collision avoidance plate 3, the guide rods 31 movably passing through the baffle 2, a limit part 311 fixedly provided at the rear end of the guide rods 31, and a boat-shaped buffer bracket 12 fixedly connected to the front side of the baffle 2 by bolts 13, with two boat-shaped buffer brackets 12 arranged vertically on the front side of the baffle 2. The middle part of the boat-shaped buffer bracket 12 is fixedly connected to the baffle 2 by bolts 13. Both ends of the boat-shaped buffer bracket 12 are rotatably connected to rollers 121 via axles. The rollers 121 are in contact with the rear side wall of the anti-collision plate 3. Through the reflective strip 5, the strip warning light 7 and the warning sign 8, the vehicle can be warned and the driver can be reminded to avoid collision. When the vehicle hits the buffer pad 4, the deformation of the buffer pad 4 can buffer the vehicle once. Then, as the buffer pad 4 drives the anti-collision plate 3 to move backward along the guide rod 31, it can buffer the boat-shaped buffer bracket 12. 2. The compression causes the boat-shaped buffer bracket 12 to expand outward and deform, thus providing secondary buffer protection for the vehicle and further improving the impact resistance. A warning sign 8 is fixedly connected to the top of the baffle 2 via a support rod 6. A strip warning light 7 is fixedly connected to the support rod 6 below the warning sign 8. The strip warning light 7 has an internal battery for power supply. During emergency construction of highway projects, the anti-collision device can be placed stably in a suitable position. By turning on the strip warning light 7, it can work in conjunction with the reflective strip 5 and the warning sign 8 to alert the driver and passengers in the vehicle. The collision avoidance warning is that when a vehicle hits the buffer pad 4, the buffer pad 4 will deform under the pressure, providing initial cushioning for the vehicle. Then, the buffer pad 4 can drive the anti-collision plate 3 to move backward along the guide rod 31. At this time, the backward movement of the anti-collision plate 3 can compress the boat-shaped buffer bracket 12, causing the two ends of the boat-shaped buffer bracket 12 to open outward and deform. During the process of the two ends of the boat-shaped buffer bracket 12 opening outward, the roller 121 can roll along the rear side wall of the anti-collision plate 3. The deformation of the boat-shaped buffer bracket 12 can provide secondary cushioning protection for the vehicle.

[0022] A column 9 is fixedly connected to the top of the base 1 on the rear side of the baffle 2. Two columns 9 are arranged side by side on the top of the base 1. A concrete block 10 is fitted over the column 9. The concrete block 10 has a through hole 101. The concrete block 10 is fitted over the outside of the column 9 through the through hole 101. The concrete block 10 is placed on the top of the base 1. The two sides of the concrete block 10 have symmetrical grooves 102. An anti-slip pad 11 is fixedly connected to the bottom of the base 1. By pressing the concrete block 10 on the bottom of the base 1 and by setting the anti-slip pad 11 on the bottom of the base 1, the anti-collision device can be more stable. It can prevent the anti-collision device from easily moving or tilting after a vehicle collision. Compared with using concrete anti-collision piles, it can better protect the vehicle. At the same time, it does not need to be fixed by driving ground nails into the ground, which can reduce the damage to the ground. After the anti-collision device is placed in a suitable position, the concrete block 10 can be fitted over the outside of the column 9, so that the concrete block 10 presses on the base 1.

[0023] Working principle: During emergency construction of highway engineering, the anti-collision device can be placed stably in a suitable position. After the anti-collision device is placed in the suitable position, the concrete block 10 can be put on the outside of the column 9, so that the concrete block 10 presses on the base 1. By turning on the strip warning light 7, it can work with the reflective strip 5 and warning sign 8 to remind the driver of the vehicle to avoid collision. When the vehicle hits the buffer pad 4, the buffer pad 4 will deform after being squeezed, providing a buffer for the vehicle. Then the buffer pad 4 can drive the anti-collision plate 3 to move backward along the guide rod 31. At this time, the backward movement of the anti-collision plate 3 can squeeze the boat-shaped buffer bracket 12, causing the two ends of the boat-shaped buffer bracket 12 to open outward and deform. During the process of the two ends of the boat-shaped buffer bracket 12 opening outward, the roller 121 can roll along the rear side wall of the anti-collision plate 3. The deformation of the boat-shaped buffer bracket 12 can provide a secondary buffer protection for the vehicle.
