How to ensure the safety of road maintenance workers and equipment has become a problem for a while, especially in highway road surface maintenance and guardrail maintenance, traffic accident handling and other situations, a road collision avoidance vehicle is needed to prevent fast-moving vehicles from hitting road maintenance personnel.

[0003] Prior art, for example, invented a multifunctional anti-collision vehicle, application number CN202310424924.3. By setting an anti-collision operation mechanism, when in use, the weight of the whole vehicle is increased by filling water in the water tank, thereby solving the problem that the weight of the existing anti-collision vehicle is light and the whole vehicle is easily displaced when a collision occurs.

[0004] At present, there is still a lack of an anti-collision vehicle that can facilitate the deployment of relevant components, realize the gradual impact and deceleration of the vehicle, and finally make the tire arc hug the vehicle tire, and the vehicle hit the airbag to achieve vehicle anti-collision.

[0005] Therefore, in view of the above problems, a road construction maintenance warning anti-collision vehicle is proposed to solve the above problems. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention develops a road construction maintenance warning and anti-collision vehicle. The invention facilitates the deployment of related components, realizes the gradual deceleration of the vehicle by collision, and finally makes the tire arc hug the vehicle tire, and the vehicle hits the airbag to achieve vehicle anti-collision.

[0007] The technical solution to the technical problem solved by the present invention is as follows: the present invention provides a road construction maintenance warning anti-collision vehicle, comprising: a main vehicle assembly, several groups of car assembly assemblies, a terminal anti-collision assembly and several groups of intermediate anti-collision assemblies, wherein the terminal anti-collision assembly and each of the intermediate anti-collision assemblies are respectively installed on the corresponding car assembly; the main vehicle assembly comprises a carrier vehicle, and the carrier vehicle is connected to a symmetrical track groove; the car assembly comprises a frame, and adjacent frames are rotatably connected by two connecting rods, respectively, and the four corners of the frame are respectively connected to wheels by bearings, and each of the wheels is respectively provided with matching corresponding track grooves, the frame is connected to a guide round rod, and the front side of the frame is connected to an impact plate; the terminal anti-collision assembly comprises an airbag and an impact L plate, the airbag is connected to the impact plate, the impact L plate is connected to a front slide plate, the front side of the guide round rod passes through the front slide plate, the front slide plate is connected to the corresponding frame through a front spring, and the front spring ring sleeve corresponds to the guide round rod. By using a carrier vehicle, it is convenient to transport and transfer the device. By using a split vehicle assembly, it is convenient to realize the terminal anti-collision assembly and one end of several groups of intermediate anti-collision assemblies. The carrier vehicle's undercarriage is controlled to lift up so that the rear of the vehicle is close to the ground. Wooden boards are used to cover the rear of the vehicle and the ground, and the adjacent frames are rotated to connect the connecting rods to facilitate the movement of the frames from the carrier vehicle to the ground. When a collision occurs, the vehicle first hits the intermediate anti-collision assembly, then hits the impact L plate and airbag, and finally hits the impact plate and the carrier vehicle, realizing multi-level energy buffering and better anti-collision effect.

[0009] As an optimization, the front end of each of the movable plates is respectively connected to a rear fluorescent impact barrel. While the rear fluorescent impact barrel serves as a warning, when the vehicle wheels contact the welding plate, the rear fluorescent impact barrel is driven to move inward and contact the vehicle, prompting the vehicle to maintain a central position and move, making it easier to move to the next set of intermediate anti-collision components and terminal anti-collision components.

[0011] As an optimization, each tire arc is connected to a set of mounting rods, each mounting rod is connected to a Z-shaped shaft, each Z-shaped shaft is connected to an eccentric column, each Z-shaped shaft is connected to a linkage rod, each intermediate double-axis block is connected to a Z power shaft, and each Z power shaft is connected to a corresponding Z-shaped shaft. When the tire arc swings and rises rapidly, the farther the eccentric column is from the contact strip, the larger the distance between it and the tire arc, and the closer it is to the wheel, the better the anti-collision effect.

[0012] As an optimization, the front skateboard is rotatably connected to the symmetrical first swing arm, the symmetrical first swing arm is rotatably connected to the second swing arm, the frontmost frame is connected to the symmetrical mounting seat, the symmetrical mounting seat is rotatably connected to the L axis, the symmetrical second swing arm is connected to the corresponding L axis, and the symmetrical L axis is connected to the front fluorescent impact barrel.

The above technical solution has the following advantages or beneficial effects: 1. The carrier vehicle and frame of the device are respectively equipped with warning lights and fluorescent strips, which, together with the front fluorescent impact barrel and the rear fluorescent impact barrel, play a good warning role; by using a carrier vehicle, it is convenient to transport and transfer the device; when a collision occurs, the vehicle first hits the middle anti-collision component, then hits the impact L plate and airbag, and finally hits the impact plate and the carrier vehicle, realizing multi-level energy buffering and better anti-collision effect.

[0016] 2. This device uses a rear spring and a welding plate. When the vehicle hits the welding plate, the kinetic energy is converted into the energy of the welding plate breaking and the deformation energy of the rear spring is offset. The vehicle wheels drive the welding plate to move inward and forward, and multi-level collision occurs.

By using the carrier 11, it is convenient to realize the transportation and transfer of the device, and the split car assembly 3 is used to facilitate the realization of one end of the terminal anti-collision assembly 2 and several groups of intermediate anti-collision assemblies 4, and the carrier 11 is controlled to lift the vehicle plate so that the rear of the vehicle is close to the ground, and wooden boards are used to be placed between the rear of the vehicle and the ground, and the adjacent frames 34 are rotatably connected to the connecting rod 33, so that the frames 34 are convenient to move from the carrier 11 to the ground. When a collision occurs, the vehicle first hits the middle anti-collision component 4, then hits the impact L plate 22 and the airbag 21, and finally hits the impact plate 31 and the carrier 11, thereby achieving multi-level energy buffering and better anti-collision effect.

[0034] The intermediate anti-collision component 4 includes a group of rear slide plates 45, each of which is respectively penetrated by the corresponding guide round rod 37, each of which is respectively connected to the end of the corresponding rear spring 46, the frontmost rear spring 46 is connected to the corresponding frame 34, the rear spring 46 is sleeved with the corresponding guide round rod 37, the frame 34 is provided with two groups of symmetrical straight grooves 35, each of which is respectively provided with a short round rod 36, each of which is respectively connected to the frame 34, the two ends of the symmetrical movable plates 42 are respectively arranged in the corresponding straight grooves 35, the two ends of the symmetrical movable plates 42 are respectively penetrated by the corresponding short round rod 36, each of the rear slide plates 45 is respectively rotatably connected to one end of the mounting connecting rod 43, the other end of each mounting connecting rod 43 is respectively rotatably connected to the corresponding movable plate 42, and each mounting connecting rod 43 is respectively connected to the welding plate 44. By adopting the rear spring 46 and the welding plate 44, when the vehicle hits the welding plate 44, the kinetic energy is converted into energy of breaking the welding plate 44 and offsetting the deformation energy of the rear spring 46, and the vehicle wheel drives the welding plate 44 to move inward and forward, resulting in multiple levels of collision.

[0035] The impact plate 31 is connected to a symmetrical hook 38 , and an electric hoist is installed on the carrier 11 , and the steel wire of the electric hoist is connected to the hook 38 , which is convenient for loading and unloading the vehicle splitter assembly 3 , the terminal anti-collision assembly 2 and the intermediate anti-collision assembly 4 .

[0047] Embodiment 5: This embodiment is further elaborated on the basis of embodiment 1, 2, 3 or 4, and the front end of each movable plate 42 is respectively connected to the rear fluorescent impact barrel 41. While the rear fluorescent impact barrel 41 serves as a warning, when the vehicle wheels contact the welding plate 44, the rear fluorescent impact barrel 41 is driven to move inward and contact the vehicle, prompting the vehicle to maintain a central position and move, so as to facilitate movement to the next group of intermediate anti-collision components 4 and terminal anti-collision components 2.

[0048] The workflow of this embodiment is: The moving plate 42 drives the rear fluorescent impact barrel 41 to move inward to contact the vehicle, so as to cause the vehicle to move while maintaining a central position.

[0049] The carrier vehicle 11 and the frame 34 of the device are respectively equipped with warning lights and fluorescent strips, which, together with the front fluorescent impact barrel 27 and the rear fluorescent impact barrel 41, play a good warning role; by adopting the carrier vehicle 11, the transportation and transfer of the device are convenient; when a collision occurs, the vehicle first hits the middle anti-collision component 4, then hits the impact L plate 22 and the airbag 21, and finally hits the impact plate 31 and the carrier vehicle 11, realizing multi-level energy buffering and better anti-collision effect.

[0050] This device uses the rear spring 46 and the welding plate 44. When the vehicle hits the welding plate 44, the kinetic energy is converted into the energy of the welding plate 44 breaking and the deformation energy of the rear spring 46 is offset. The vehicle wheel drives the welding plate 44 to move inward and forward, and a multi-stage collision occurs. When the vehicle wheel contacts the welding plate 44, the rear fluorescent impact barrel 41 is driven to move inward and contact the vehicle, so that the vehicle moves in the center position, and moves to the next set of intermediate anti-collision components 4 and terminal anti-collision components 2.

[0051] The device adopts the tire arc 214. When the front wheel of the vehicle contacts the rear tire arc 214, the rear tire arc 214 is driven to swing downward, so that the middle double-axis block 224 moves to contact the first block 221, and the tire arc 214 swings to the lowermost position. Then the front wheel quickly contacts the contact strip 218, so that it moves downward quickly, squeezes the vertical spring 213, and the tire arc 214 swings and rises quickly, hugs the front wheel, and limits the wheel. When the tire arc 214 swings and rises quickly, the farther the eccentric column 231 is from the contact strip 218, the larger the distance between it and the tire arc 214, and the closer it is to the wheel, the better the anti-collision effect.

[0052] Although the above describes the specific implementation mode of the invention in conjunction with the drawings, it is not intended to limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
