Description

Technical Field

[0001] This utility model relates to the field of road transportation engineering technology, and in particular to a collision avoidance device for road transportation engineering. Background Technology

[0002] Commonly used anti-collision devices in road transportation engineering include curbs, guardrails, bollards, and speed bumps. These anti-collision devices are key facilities to ensure road traffic safety, mitigating the impact force when vehicles collide and guiding the vehicle's trajectory, thereby reducing accident losses.

[0003] Existing technology patent document CN222477299U discloses a collision avoidance device for road traffic engineering, including a collision avoidance component. The collision avoidance component includes a base, support rods, reinforcing rods, a connecting structure, a top plate, reinforcing blocks, and a mounting plate. Support rods are evenly fixed to the top of the base, and a top plate is fixed to the top of each support rod. Reinforcing rods are evenly fixed to both sides of the support rods. This invention, by providing a connecting structure, allows the upper connecting plate to move to the top of the lower connecting plate during assembly. After the upper and lower connecting plates are fitted together, fixing bolts are inserted into the first and second connecting holes to securely connect the bottom of the collision avoidance device, increasing its stability and achieving a stable connection function, thus improving the stability of the collision avoidance device during use.

[0004] Existing road traffic engineering anti-collision devices typically use only anti-collision components to buffer impact forces, which is not convenient for first unloading the impact force and then buffering it, resulting in low practicality and thus reduced safety. Utility Model Content

[0005] The purpose of this utility model is to provide a collision avoidance device for road transportation engineering, which solves the problem mentioned in the background art that collision avoidance devices usually only use collision avoidance components to buffer the impact force.

[0007] The fixed column is fixedly installed with a base at its bottom end, and a base plate is fixedly installed with the bottom end of the base. A reinforcing plate is fixedly installed between the fixed columns. The reinforcing plate is located on one side of the fixed frame and is fixedly connected to the fixed frame, which facilitates the improvement of the stability of the fixed frame installation and enhances its practicality.

[0008] The base plate has through slots on both sides of the base at its inner end, and ground bolts are installed on both sides of the base at the top of the base plate. The ground bolts pass through the through slots and extend to the bottom of the base plate, which facilitates the installation of the anti-collision device.

[0009] The fixed column has a supporting diagonal rod fixedly installed on one side away from the fixed frame. A connecting plate is fixedly installed at the bottom of the supporting diagonal rod. The four corners of the connecting plate have through slots, and the four corners of the connecting plate have ground bolts. The ground bolts penetrate through the through slots and extend to the bottom of the connecting plate. The supporting diagonal rod and the fixed column form a triangle with the ground. The supporting diagonal rod is connected to the ground through the connecting plate and the ground bolts, forming a stable structure and improving the stability of the anti-collision device.

[0010] The mounting frame has positioning grooves on both sides, and positioning shafts are fixedly installed on both sides of the unloading roller. The positioning shafts are adapted to the positioning grooves and are movably connected to the positioning grooves. The unloading roller is connected to the mounting frame through the positioning shafts and positioning grooves. After contacting a car, the roller can disperse the lateral impact force by rolling, guiding the vehicle to slide along the surface of the anti-collision device.

[0011] The buffer groove has positioning grooves on both sides, and positioning sliders are fixedly installed on both sides of the connecting plate. The positioning sliders are located at the inner end of the positioning grooves and are movably connected to the positioning grooves. The positioning grooves and positioning sliders facilitate the positioning of the connecting plate.

[0012] This utility model discloses a collision avoidance device for road transportation engineering. It includes a buffer damper and a stress-relief roller. The stress-relief roller is connected to the mounting frame via a positioning groove and a positioning shaft. When a vehicle is impacted by an external force, it contacts the stress-relief roller. The roller's rolling action disperses the lateral impact force, guiding the vehicle to slide along the surface of the collision avoidance device. After partially dissipating the impact force, the stress-relief roller transmits the remaining impact force to the buffer damper via the mounting frame and connecting plate. The buffer damper generates damping force through liquid throttling, further buffering the impact force. A supporting diagonal rod is installed, forming a triangle with the ground along with the fixed column. The supporting diagonal rod is connected to the ground via a connecting plate and two ground bolts, forming a stable structure and improving the device's stability. A positioning slider and a positioning groove can position the connecting plate. Attached Figure Description
