Description

Technical Field

[0001] This invention relates to the field of highway engineering safety equipment technology, specifically to a collision avoidance device for highway engineering safety management. Background Technology

[0002] During highway construction, to ensure the safety of the construction area, crash barriers are often simply enclosed by sheet metal and warning signs. However, when vehicles travel at high speeds or lose control, the metal barriers are insufficient to stop them, allowing vehicles to enter the construction area. This renders the crash barriers ineffective in resisting impacts and fails to protect vehicles, posing a life-threatening risk to both drivers and construction workers. Therefore, a new type of crash barrier is needed to stop oncoming vehicles and protect the safety of drivers and workers.

[0003] In existing technical solutions, the device cannot effectively absorb collision energy when a vehicle collides, which can easily lead to vehicle damage and personal injury. At the same time, the device itself is also easily destroyed in a collision and cannot play an effective protective role. Summary of the Invention

[0004] The purpose of this invention is to provide a collision avoidance device for highway engineering safety management, so as to solve the problems mentioned in the background art.

Also includes: A buffer protection mechanism is installed inside the collision barrel to buffer and protect the collision barrel from damage upon impact. A sliding mechanism is provided at the upper and lower ends of the inner cavity of the collision box, which is used for sliding the collision barrel to further buffer the collision force. A connecting mechanism is provided at the connection between the main frame and the anti-collision side plate. The connecting mechanism is welded to the main frame and fixed to the anti-collision side plate by bolts. The reinforcement mechanism is located on both sides of the main frame and supports and reinforces the main frame in a triangular support manner.

[0006] A further improvement of the technical solution of the present invention is that: the buffer protection mechanism includes a buffer layer and an outer rubber pad, the outer side of the buffer layer is fixedly installed on the inner side of the collision barrel, a spring column is movably installed on the inner side of the buffer layer, and a buffer pressure spring column is fixedly installed on the inner side of the outer rubber pad.

[0007] A further improvement of the technical solution of the present invention is that: the surface of the outer rubber pad is provided with a textured surface and the thickness is 15 cm, and it is made of high-strength wear-resistant rubber material.

[0008] A further improvement of the technical solution of the present invention is that: the sliding mechanism includes a slider and a connecting plate, the top of the slider is fixedly connected to the bottom of the connecting shaft, a pushing block is fixedly connected to the side of the slider, one side of the pushing block is movably sleeved on one end of the connecting plate, and telescopic spring columns are movably installed at both ends of the connecting plate and the pushing block.

[0009] A further improvement of the technical solution of the present invention is that: the connecting mechanism includes a plug-in block, a connecting block and a protective sleeve, the connecting block has a connecting port on its inner side, the connecting port is movably installed on the outer side of the protective sleeve, the protective sleeve is movably fitted with a plug-in post, the other end of the plug-in post is fixedly installed on the inner side of the plug-in block, and the plug-in block is fixedly installed on the front side of the main frame.

[0010] A further improvement of the technical solution of the present invention is that a spring-loaded post is movably installed on the inner side of the protective sleeve, and a clamping block is fixedly installed on one end of the spring-loaded post.

[0011] A further improvement of the technical solution of the present invention is that: arc-shaped clamping blocks are movably installed on both sides of the inner wall of the connection port, a push rod is fixedly connected to the side of the arc-shaped clamping block, a limit block is fixedly installed at the other end of the push rod, and a fixing bolt is threadedly connected to the top of the limit block.

[0012] A further improvement of the technical solution of the present invention is that: the reinforcement mechanism includes a support rod and a sliding groove, an adjusting block is movably installed inside the sliding groove, and the adjusting block is movably connected to one end of the support rod.

[0013] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows: 1. This invention provides a collision avoidance device for highway engineering safety management. When a vehicle collides with the device, the outer rubber pad on the outside of the collision barrel comes into contact. The outer rubber pad is made of high-strength wear-resistant rubber material and uses its flexibility to provide buffer protection. At the same time, the outer rubber pad is squeezed inward under force, and the buffer pressure spring column is compressed and contracted synchronously, converting part of the collision energy into elastic potential energy, thus initially buffering the collision impact force. Subsequently, after the buffer layer is compressed, it drives the inner movable spring column to contract. The spring column further absorbs the collision energy through its own elastic deformation, forming a synergistic buffer with the buffer pressure spring column, reducing the stress load on the collision barrel and preventing it from being damaged due to excessive instantaneous impact force.

[0014] 2. This invention provides a collision avoidance device for highway engineering safety management. When the collision barrel is subjected to force, the connecting shaft displaces accordingly, causing a slider fixedly connected to the bottom to move within the collision chamber. The pushing block on the side of the slider moves with the slider, applying a pushing force to one end of the connecting plate. The pushing block slides within the connecting plate. At this time, the telescopic spring columns movably installed at both ends of the connecting plate and the pushing block are stretched or compressed, converting some of the kinetic energy into elastic potential energy through elastic deformation, further buffering the collision force and improving the device's protective function.

[0015] 3. This invention provides a collision avoidance device for highway engineering safety management. The connecting seat and the connecting plate are tightly connected by high-strength bolts, which enhances the connection strength between the collision avoidance side plate and the main frame. When a collision occurs, some of the impact force is distributed to the main frame, preventing the collision avoidance side plate from falling off due to excessive force. In addition, the rebound post and clamping block inside the protective sleeve have a buffering clamping function. Part of the force generated by the collision will be transmitted to the connecting block and the plug-in post. The rebound post plays a buffering role with its own elasticity, further buffering the protective connection mechanism. The synergistic effect of the overall connection structure not only ensures sufficient connection strength, but also reduces the negative impact of the collision through the buffering design, significantly improving the reliability and safety of the device when dealing with collisions.

[0016] This invention provides a collision avoidance device for highway engineering safety management. When the main frame is installed in conjunction with the embedded parts, the adjusting block is pushed to move inside the sliding groove, and the adjusting support rod is rotated to drive the support rod to be triangularly supported and fixed on both sides of the main frame, thereby achieving the function of reinforcement installation. The reinforced main frame can more stably bear and disperse the collision force, avoid the weakening of the protective function due to frame displacement, further enhance the resistance to collision, and improve the protective performance of the main frame.

[0019] The present invention will be further described in detail below with reference to embodiments: like Figure 1-7 As shown, the present invention has the following three specific embodiments.

[0020] Example 1 This invention provides a collision avoidance device for highway engineering safety management, including a main frame 1, an embedded part 2 fixedly installed at the bottom of the main frame 1, collision avoidance side plates 3 fixedly installed at the upper and lower ends of the front side of the main frame 1, a collision box 4 fixedly installed inside the collision avoidance side plates 3, a connecting shaft 41 movably installed inside the collision box 4, a collision barrel 42 fixedly installed on the outside of the connecting shaft 41, and a reflective strip 5 fixedly installed at the top of the front side of the main frame 1. Also includes: A buffer protection mechanism is installed inside the collision barrel 42 to buffer and protect the collision barrel 42 from collision damage. A sliding mechanism is installed at the upper and lower ends of the inner cavity of the collision box 4, which is used for the collision barrel 42 to slide during collision, further buffering the collision force. A connecting mechanism is provided at the connection between the main frame 1 and the anti-collision side plate 3. The connecting mechanism is welded to the main frame 1 and fixed to the anti-collision side plate 3 by bolts. The reinforcement mechanism is set on both sides of the main frame 1 and supports and reinforces the main frame 1 in a triangular support manner.

[0021] like Figure 1 As shown, when a passing vehicle or other object collides with the device, it first comes into contact with the collision barrel 42. Upon impact, the internal buffer mechanism of the collision barrel 42 immediately activates, absorbing some of the collision energy through its own deformation and further converting the impact force into elastic potential energy. This effectively reduces the probability of the collision barrel 42 being damaged due to excessive instantaneous force. Simultaneously, while the collision barrel 42 is subjected to force, the connecting shaft 41 causes the collision barrel 42 to displace within the collision box 4. At this time, the sliding mechanism begins to operate, buffering the force through internal sliding. Furthermore, the main frame 1, serving as the supporting foundation for the entire device, is firmly connected to the anti-collision side plate 3 via the connecting mechanism, dispersing some of the impact force onto the main frame 1 upon collision. To prevent the side impact protection plate 3 from falling off due to excessive stress, the reinforcement mechanisms on both sides of the main frame 1 enhance overall stability using the triangular support principle, effectively preventing the main frame 1 from tilting or shifting. In conjunction with the pre-embedded parts 2 at the bottom of the main frame 1, which are deeply embedded in the concrete foundation, they provide strong anchoring force for the device, further resisting the displacement tendency caused by the collision and ensuring that the entire device remains stable during the collision. In addition, the reflective strip 5 at the top front of the main frame 1 can reflect vehicle lights at night or in low-light conditions, reminding the driver to pay attention and avoid collisions in advance, thus reducing the probability of collision accidents.

[0022] Example 2 The difference from Embodiment 1 is that this embodiment discloses a buffer protection mechanism including a buffer layer 421 and an outer rubber pad 423. The outer side of the buffer layer 421 is fixedly installed on the inner side of the collision barrel 42. A spring post 422 is movably installed on the inner side of the buffer layer 421. A buffer pressure spring post 424 is fixedly installed on the inner side of the outer rubber pad 423. The surface of the outer rubber pad 423 is provided with a textured surface and has a thickness of 15 cm. It is made of high-strength wear-resistant rubber. The sliding mechanism includes a slider 411 and a connecting plate 413. The top of the slider 411 is fixedly connected to the bottom of the connecting shaft 41. A pushing block 412 is fixedly connected to the side of the slider 411. One side of the pushing block 412 is movably sleeved on one end of the connecting plate 413. Telescopic spring posts 414 are movably installed at both ends of the connecting plate 413 and the pushing block 412.

[0023] like Figure 2 , 3As shown, when a passing vehicle or other object collides with the device, it first contacts the outer rubber pad 423 on the outside of the collision barrel 42. The outer rubber pad 423 is made of high-strength, wear-resistant rubber with a thickness of 15 cm. The textured surface increases the friction with the colliding object, slowing down the collision speed. At the same time, the outer rubber pad 423 is compressed inward, and the buffer spring column 424 fixed inside it is compressed and contracts synchronously, converting some of the collision energy into elastic potential energy, initially buffering the impact force. The buffer layer 421 fixed inside it then begins to function. After the buffer layer 421 is compressed, it causes the spring column 422, which is movably installed inside, to contract. The spring column 422 further absorbs the collision energy through its own elastic deformation, forming a synergistic buffer with the buffer spring column 424, reducing the stress load on the collision barrel 42 and preventing it from being damaged due to excessive instantaneous impact force. While the collision barrel 42 is under force, the connecting shaft 41 is displaced, causing the slider 411 fixedly connected at the bottom to move within the collision box 4. The pushing block 412 on the side of the slider 411 moves with the slider 411, applying a pushing force to one end of the connecting plate 413. The pushing block 412 slides and engages with the connecting plate 413. At this time, the telescopic spring columns 414 movably mounted at both ends of the connecting plate 413 and the pushing block 412 are stretched or compressed, converting part of the kinetic energy into elastic potential energy through elastic deformation, further buffering the collision force.

[0024] Example 3 The difference from Embodiment 2 is that this embodiment discloses that the connecting mechanism includes a plug-in block 11, a connecting block 12, and a protective sleeve 112. A connecting port 121 is provided on the inner side of the connecting block 121. The interior of the connecting port 121 is movably installed on the outside of the protective sleeve 112. A plug-in post 111 is movably sleeved inside the protective sleeve 112. The other end of the plug-in post 111 is fixedly installed on the inner side of the plug-in block 11. The plug-in block 11 is fixedly installed on the front side of the main frame 1. A spring-loaded post 113 is movably installed on the inner side of the protective sleeve 112. A clamping block 114 is fixedly installed on one end of the spring-loaded post 113. Arc-shaped clamping blocks 125 are movably installed on both sides of the inner wall of the connecting port 121. A push rod 124 is fixedly connected to the side of the arc-shaped clamping block 125. A limit block 123 is fixedly installed on the other end of the push rod 124. A fixing bolt 122 is threadedly connected to the top of the limit block 123.

[0025] like Figure 5 , 6As shown in Figure 7, the connecting mechanism includes a connecting seat welded to the main frame 1 and a connecting plate fixed to the anti-collision side plate 3. The connecting seat and the connecting plate are tightly connected by high-strength bolts, ensuring the connection strength between the anti-collision side plate 3 and the main frame 1. When subjected to a collision, part of the impact force is distributed to the main frame 1, preventing the anti-collision side plate 3 from being subjected to excessive force and falling off. In addition, by utilizing the buffering and clamping function of the rebound post 113 and the clamping block 114 inside the protective sleeve 112, part of the force generated by the collision will be transmitted to the connecting block 12 and the plug-in post 111. The elasticity of the rebound post 113 is used for buffering, further buffering and protecting the connecting mechanism. It also works with the arc-shaped clamping block 125 and the push rod 124 to fix and clamp the plug-in post 111, increasing the fixation of the connection and improving the connection strength.

[0026] The difference from Embodiment 3 is that this embodiment discloses a support rod 6 and an adjusting block 61. The reinforcement mechanism includes a support rod 6 and a sliding groove 62. The adjusting block 61 is movably installed inside the sliding groove 62, and the adjusting block 61 is movably connected to one end of the support rod 6.

[0027] like Figure 4 As shown, when the main frame 1 is installed in conjunction with the embedded part 2, the adjusting block 61 is pushed to move inside the sliding groove 62, and the adjusting support rod 6 is rotated to drive the support rod 6 to be fixed in a triangular shape on both sides of the main frame 1, thereby achieving the function of reinforcing the installation, preventing the main frame 1 from shifting in the event of a collision, and increasing the protective function of the main frame 1.

[0028] The working principle of the anti-collision device used for safety management in this highway project will be explained in detail below.

[0029] like Figure 1-7As shown, when a passing vehicle or other object collides with the device, it first comes into contact with the collision barrel 42. After the collision barrel 42 is subjected to impact, the outer rubber pad 423, made of 15 cm thick high-strength wear-resistant rubber, has a textured surface that increases friction with the colliding object, slowing down the collision speed. At the same time, the outer rubber pad 423 is compressed inward, and the buffer elastic column 424 fixed inside it is compressed and contracts synchronously, converting some of the collision energy into elastic potential energy, initially buffering the impact force. The buffer layer 421 fixed inside then begins to function. When the buffer layer 421 is compressed, it causes the inner movable spring column 422 to contract. The spring column 422 further absorbs the collision energy through its own elastic deformation, forming a synergistic buffer with the buffer pressure spring column 424 to reduce the stress load on the collision barrel 42 and prevent it from being damaged due to excessive instantaneous impact force. At the same time as the collision barrel 42 is subjected to force, the connecting shaft 41 causes the collision barrel 42 to move within the collision box 4. At this time, the sliding mechanism starts to operate, and the force is absorbed by the internal sliding buffer part. In addition, the main frame 1 serves as the supporting foundation of the entire device and is firmly connected to the anti-collision side plate 3 through the connecting mechanism, which distributes part of the impact force when it is hit. The reinforcements are distributed onto the main frame 1 to prevent the side panels 3 from being overloaded and falling off. Meanwhile, the reinforcement mechanisms on both sides of the main frame 1 enhance overall stability using the triangular support principle, effectively preventing the main frame 1 from tilting or shifting. In conjunction with the pre-embedded parts 2 at the bottom of the main frame 1, which are deeply embedded in the concrete foundation, they provide strong anchoring force for the device, further resisting the displacement tendency caused by the collision and ensuring that the entire device remains stable during the collision. In addition, the reflective strip 5 at the top front of the main frame 1 can reflect vehicle lights at night or in low-light conditions, reminding the driver to pay attention and avoid collisions in advance, thus reducing the probability of collision accidents.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
