Detailed implementation manners

[0025] In order to make the technical problems, technical solutions and beneficial effects solved by this application clearer, the following further details this application in combination with the attached drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0026] Such as Figure 1-8The anti-collision buffer vehicle applied to road construction operations shown in the figure includes a vehicle body 1 and an anti-collision device 2 provided at the rear end of the vehicle body 1. The anti-collision device 2 includes an anti-collision bracket 21 provided on the vehicle body 1 and a buffer mechanism 22 hinged on the vehicle body 1 that can be flipped to fit or disengage from the anti-collision bracket 21. Specifically, a first fixed seat 3 is provided on the vehicle body 1, a first connection seat 4 hinged to the first fixed seat 3 is provided on the buffer mechanism 22, and a power mechanism 5 for driving the buffer mechanism 22 to flip and fit or disengage from the anti-collision bracket 21 is connected between the first connection seat 4 and the first fixed seat 3. The buffer mechanism 22 includes a plurality of buffer layers 221 made of energy-absorbing materials. The operation steps of the present invention are as follows: During road construction, the anti-collision buffer vehicle is parked behind the construction position, the power mechanism 5 drives the buffer mechanism 22 to flip and disengage from the anti-collision bracket 21, so that the buffer mechanism 22 is placed on the road surface. When an accident occurs, the buffer mechanism 22 absorbs kinetic energy through multiple buffer layers 221, reduces the impact force, enables the accident vehicle to stop quickly or effectively reduces its speed, protects the safety of construction workers. At the same time, the setting of the power mechanism 5 realizes the automation of the flipping of the buffer mechanism 22 and improves the operation efficiency.

[0027] Further, a second fixed seat 6 is provided on the vehicle body 1, and a second connection seat 7 hinged to the second fixed seat 6 is provided on the buffer mechanism 22. This structure realizes the double hinge connection between the buffer mechanism 22 and the vehicle body 1 and improves the structural stability.

[0028] Specifically, the anti-collision bracket 21 includes an outer frame 211. A cross bar 212 is provided on the outer frame 211 to divide it into an upper frame and a lower frame. Two diagonal bars 213 extending along its diagonal are provided on the upper frame 2111, and the two diagonal bars 213 are cross-set in an "X" shape. The anti-collision bracket 21 adopts a frame structure and can play a good buffering role when it is subjected to external impact force. Among them, the two diagonal bars 213 are in an "X" shape, and they deform towards the middle when being impacted, avoiding being thrown outwards after breaking and causing secondary accidents and expanding losses. Specifically, the outer frame 211 is welded by multiple hollow profiles, the cross bar 212 and the diagonal bars 213 are both hollow profiles, a first through hole communicating with its inner cavity is provided on the outer frame 211, a second through hole communicating with its inner cavity is provided on the cross bar 212, and a third through hole communicating with its inner cavity is provided on the diagonal bar 213. The hollow structure with holes can effectively reduce the impact force and has a good buffering effect.

[0029] Specifically, a cable 10 is connected between the outer frame 211 and the vehicle body 1. The setting of the cable 10 can improve the stability between the outer frame 211 and the vehicle body 1.

[0030] Specifically, the buffer mechanism 22 includes a housing 222 and a buffer cavity provided inside the housing 222. A plurality of buffer partitions 223 are provided inside the housing 222 to divide the buffer cavity into a plurality of sub-buffer cavities. A plurality of the buffer layers 221 are provided in the sub-buffer cavities. The housing 222 is a hexagonal prism. The buffer partitions 223 are parallel to the diagonal plane of the housing 222. The plurality of buffer partitions 223 are spaced apart in the extending direction of the diagonal plane. The plurality of buffer layers 221 are arranged parallel to the buffer partitions 223. When the present invention is placed at the rear end of a construction vehicle, the buffer mechanism 22 is laid down on the road surface. At this time, both the buffer partitions 223 and the buffer layers 221 form an angle with the ground. When an accident vehicle runs out of control and rushes towards the buffer mechanism 22, due to the decomposition of force, the force acting on the buffer partitions 223 and the buffer layers 221 is less than the impact force of the accident vehicle, reducing the impact effect. At the same time, this structure can increase the area of the buffer layer 221 and improve the buffering capacity.

[0031] Specifically, the buffer layer 221 includes two outer walls 2211 arranged in parallel and a honeycomb core 2212 provided between the two outer walls 2211. The honeycomb core 2212 includes a first honeycomb core 100 provided between the two outer walls 2211. A second honeycomb core 200 is integrally formed on the first honeycomb core 100. The first honeycomb core 100 is composed of a plurality of interconnected first sub-honeycomb cores 110. The first sub-honeycomb core 110 is a hollow regular hexagonal prism. The second honeycomb core 200 is composed of a plurality of interconnected second sub-honeycomb cores 210. The second sub-honeycomb core 210 is a hollow regular hexagonal prism. The plurality of first sub-honeycomb cores 110 evenly divide the inner cavities of the plurality of second sub-honeycomb cores 210 into three sub-inner cavities of the same size. With this structure of the honeycomb core 2212, its buffer space and buffer area can be increased, and its buffer effect can be improved.

[0032] Specifically, the honeycomb core 2212 can also be wavy. This structure is simple and convenient to implement. At the same time, it has a large buffer space and buffer area and a good buffer effect.
