Description

Technical Field

[0001] This invention belongs to the field of highway construction technology, specifically relating to a collision avoidance device for highway construction and its usage method. Background Technology

[0002] Crash barriers are industrial "protective barriers" primarily used for the protection of equipment and facilities in factories, workshops, and warehouses. They are commonly made of steel, such as round steel pipes, square steel pipes, or profiled steel sheets. Highway crash barriers are among the most important traffic infrastructures. my country's expressways, which began developing in the 1980s, play a significant role in national economic and social development and are crucial for highway maintenance and safety.

[0003] Chinese Patent Application No. CN202210197616.7 discloses a highway crash barrier, including a base plate. V-shaped frames are installed on both sides of the top surface of the base plate, and a crossbeam connects the top ends of the V-shaped frames. A transverse support is provided at the bottom of the crossbeam. Sleeves are fitted onto both ends of the rotating rods. A buffer body is movably fitted onto the outer end surface of the reinforcing vertical rod. An extension rod is fitted inside the sleeve, and an abutment rod is connected between the extension rods. Multiple first locking knobs are provided on the outer end surface of the sleeves. A limit buckle is provided in the middle of the top surface of the base plate. Two support rods penetrate both sides of the base plate, and friction plates are connected to the bottom ends of the support rods. This invention, by rotating the sleeves outwards to abut the abutment rods against the ground, creates a triangular structure on the overall side of the crash barrier. When a vehicle collides with it, the crash barrier is prevented from tipping over directly, allowing for longer braking time. Simultaneously, the buffer body absorbs the force generated during a frontal collision, reducing damage to the vehicle body.

[0004] During highway construction and maintenance, warning signs, guardrails, or barriers are needed to block the path of the construction site and serve only as a warning to oncoming vehicles. The aforementioned patent, by rotating the sleeve outward to abut the abutment rod against the ground, prevents the collision barrier from tipping over directly upon vehicle collision, allowing for longer braking time. Simultaneously, the buffer absorbs the force generated during the frontal collision, reducing damage to the vehicle body. However, its surface structure is vertical, making it difficult to tip over upon impact. At lower speeds, the impact may stop, but at higher speeds, the vehicle may continue forward, easily entering the highway construction area and causing collisions with construction workers or falling into the construction pit. Especially with brake failure, this could lead to even greater traffic accidents. Therefore, we propose a highway construction anti-collision device and its usage method. Summary of the Invention

[0005] The purpose of this invention is to provide a collision avoidance device for highway construction and its usage method, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A collision avoidance device for highway construction includes:

[0008] The main body has a first inclined surface on one side, a second inclined surface on the other side, a shaft groove between its top and the first inclined surface, and a third inclined surface between its top and the second inclined surface.

[0009] An arc-shaped steel plate is rotatably mounted on the upper side of the shaft groove, with a positioning shaft welded near the shaft groove and a reinforcing part provided near the third inclined surface.

[0010] The chassis is located inside the main body, and rollers are rotatably installed at its four corners. The bottom of the main body has telescopic grooves corresponding to the positions of the rollers.

[0011] A buffer mechanism, positioned between the curved steel plate and the second inclined plane, effectively reduces the impact force during a vehicle collision through elastic expansion and contraction; and

[0012] The lifting mechanism is located on the upper side of the chassis. It controls the movement of the rollers to the lower side of the telescopic groove by lifting the chassis, thereby facilitating the movement of the device.

[0013] As a preferred embodiment of the present invention, the buffer mechanism includes a plurality of strong springs, one side of each of the plurality of strong springs is fixedly connected to the third inclined surface, and the other side of each of the plurality of strong springs is fixedly connected to the reinforcing part.

[0014] As a preferred embodiment of the present invention, the lifting mechanism includes:

[0015] The frame is fixedly connected to the upper inner wall of the main body and is located on the upper side of the chassis.

[0016] The main body of the lead screw is rotatably connected between the inner walls of the frame. It consists of two opposing lead screws, one end of which passes through the frame and is fixedly connected to a mating part.

[0017] There are two lead screw sleeves, each threaded onto the circumferential surface of the corresponding lead screw.

[0018] There are two limit rods, both of which are fixedly connected to the inner wall of the frame and are located on both sides of the lead screw body.

[0019] The linkage component consists of four sets, each positioned between the chassis and the frame, connected at the four corners of the chassis to ensure stable lifting and lowering of the chassis; and

[0020] The drive component is located at the docking part and is connected to the docking part to drive the docking part to rotate, thereby controlling the lifting and lowering of the roller.

[0021] As a preferred embodiment of the present invention, each set of linkage components includes a straight rod, an upper hinge shaft, a linkage rod, and a lower hinge shaft. The upper hinge shaft is slidably connected to the surface of the limiting rod. The straight rod is fixedly connected between the upper hinge shaft and the adjacent lead screw sleeve. The lower hinge shaft is fixedly connected to the upper end of the chassis. One end of the linkage rod is rotatably connected to the upper hinge shaft, and the other end of the linkage rod is rotatably connected to the lower hinge shaft.

[0022] As a preferred embodiment of the present invention, the drive assembly includes a drive shaft, a docking pin, and a turntable. Side sealing plates are fixedly connected to both sides of the main body. The drive shaft is rotatably connected to the side sealing plate near the docking part and extends outward. The docking pin is fixedly connected to one end of the drive shaft and is detachably connected inside the docking pin. The turntable is fixedly connected to the other end of the drive shaft.

[0023] As a preferred embodiment of the present invention, the main body is provided with a flat surface near the second inclined surface, and a plurality of positioning holes are provided at the upper end of the flat surface, and a spike is inserted into each positioning hole.

[0024] In a preferred embodiment of the present invention, a solar panel is fixedly connected to the second inclined surface, an installation cavity is provided inside the spike, a storage battery is fixedly connected inside the installation cavity, a long rod is fixedly connected to the top of the second inclined surface, a warning light is fixedly connected to the upper end of the long rod, and the warning light is electrically connected to the storage battery.

[0025] In a preferred embodiment of the present invention, hollow portions are provided at both ends of the chassis, and axles are rotatably connected to each of the two hollow portions. Four rollers are respectively fixedly connected to both ends of the axles on the same side. The upper end of the chassis is provided with evenly distributed perforated portions.

[0026] As a preferred embodiment of the present invention, the bottom of the main body is provided with uniformly distributed grooves, and a reflective strip is attached to the first inclined surface.

[0027] A method for using a collision avoidance device for highway construction includes the following steps:

[0028] S1. Place the main body at a distance from the construction site, with the first inclined plane facing the oncoming direction of the vehicle, and drive multiple spikes into the ground to fix the main body to the ground;

[0029] S2. When the vehicle is moving slowly and an impact occurs, the vehicle moves slowly upward along the first inclined plane and moves to the inner arc surface of the arc steel plate. Under the pressure change of the arc steel plate, the extension and contraction of the strong spring is small. Under the action of the vehicle's own braking and the elasticity of the strong spring, the vehicle can be effectively stopped from moving forward. After releasing the accelerator and brake, the vehicle will move backward and gradually become stable.

[0030] S3. When a vehicle is traveling too fast or experiences a brake malfunction and an impact, the vehicle moves diagonally upwards along the first inclined plane at a relatively high speed and quickly moves to the inner arc surface of the arc-shaped steel plate. Under the large pressure change of the arc-shaped steel plate, the extension and contraction of the strong spring is large, and the end of the arc-shaped steel plate near the positioning shaft lifts up. As the front of the vehicle continues to lift forward, the part will push against the chassis and move upwards. The front of the vehicle will roll over along the inner arc surface of the arc-shaped steel plate, causing the vehicle traveling too fast or experiencing a brake malfunction to roll over to the side near the first inclined plane. After the vehicle rolls over, it cannot continue to move, effectively preventing the vehicle traveling too fast or experiencing a brake malfunction from causing a larger traffic accident. Moreover, the close-range rollover causes less injury to the passengers on the vehicle, protecting their lives. The vehicle wear and tear is lower compared to direct impact damage, reducing the passengers' property loss.

[0031] S4. As the construction progresses or is completed, the main body needs to be moved. When the main body needs to be moved, the spikes are separated from the ground, and then the turntable is rotated to drive the docking part to rotate. The docking part drives the main body of the screw rod to rotate, and the main body of the screw rod drives the two screw rod sleeves to move in opposite directions, thereby driving the upper hinge shaft located on the same side to move in opposite directions. Under the linkage of the linkage rod, the chassis gradually moves downward, and finally drives the roller part to move to the lower side of the main body. At this time, the main body can be moved directly to the destination.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. In this solution, the device uses a rotatable arc-shaped steel plate structure. Under the elastic action of a strong spring, it can prevent slower vehicles from continuing to move forward. The vehicle will reverse and gradually stabilize, effectively protecting passenger safety. When the vehicle is moving at a higher speed, it will move along direction B to the first inclined plane and then quickly move along direction C to the inner arc surface of the arc-shaped steel plate. The reinforcing part applies a large pressure to the strong spring in direction E. The strong spring has a large degree of extension and contraction deformation, and the end of the arc-shaped steel plate near the positioning shaft will be raised along direction D. As the front of the vehicle continues to move forward, the raised part of the arc-shaped steel plate will push against the chassis and move upward, causing the front of the vehicle to flip along the inner arc surface of the arc-shaped steel plate. This causes vehicles that are moving too fast or have brake failure to flip over to the side near the first inclined plane. After flipping, the vehicle cannot move further, effectively preventing vehicles that are moving too fast or have brake failure from causing greater traffic accidents. Moreover, the close-range flipping causes less injury to passengers on the vehicle, protecting their lives. The vehicle wear and tear is lower than that of a direct impact, reducing passenger property loss.

[0034] 2. In this design, for the sake of the main structure's sturdiness, most of the main structure is made of metal, making it difficult to move. When it is necessary to move the main body, control the rollers to move downwards, so that the rollers are on the underside of the main body. At this point, the main body can be moved directly, or it can be moved by traction equipment such as a tractor. The position can be moved at any time, saving time and effort. When it is necessary to stop, control the rollers to move upwards, so that the rollers retract into the main body, and the bottom of the main body makes direct contact with the ground, increasing the contact area with the ground and effectively increasing the friction, so that the main body is placed stably on the ground.

[0035] 3. In this design, the groove is located at the bottom of the main body, which increases the friction with the ground. The reflective strips reflect the vehicle's headlights, thus serving as a warning.

[0036] 4. The main body of this design has a tiered structure, which can be placed stably on the ground. The first and second inclined surfaces are located on opposite sides, making it less likely to overturn. Attached Figure Description

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Example

[0052] Please see Figures 1-10 The technical solution provided in this embodiment is as follows:

[0053] A collision avoidance device for highway construction includes a main body 1, an arc-shaped steel plate 3, a chassis 15, a buffer mechanism, and a lifting mechanism. The main body 1 has a first inclined surface 101 on one side and a second inclined surface 104 on the other side. A shaft groove 103 is provided between the top of the main body and the first inclined surface 101, and a third inclined surface 105 is provided between the top of the main body and the second inclined surface 104. The arc-shaped steel plate 3 is rotatably mounted on the upper side of the shaft groove 103, and a positioning shaft 301 is welded to it near the shaft groove 103. A positioning shaft 301 is also welded to it near the third inclined surface 104. A reinforcing part 303 is provided at surface 105; the chassis 15 is set inside the main body 1, and rollers 16 are rotatably provided at its four corners. The bottom of the main body 1 has a telescopic groove 17 corresponding to the position of the rollers 16; the buffer mechanism is set between the arc-shaped steel plate 3 and the second inclined surface 104, which effectively reduces the impact force when the car crashes through elastic extension and contraction; the lifting mechanism is set on the upper side of the chassis 15, which controls the rollers 16 to move to the lower side of the telescopic groove 17 by lifting the chassis 15, thereby facilitating the movement of this device.

[0054] In a specific embodiment of the present invention, the main body 1 has a trapezoidal structure and can be placed stably on the ground. The first inclined surface 101 and the second inclined surface 104 are located on opposite sides, making it less likely to tip over. The positioning shaft 301 is the axis of rotation of the arc-shaped steel plate 3. The positioning shaft 301 is rotatably connected in the shaft groove 103. The arc-shaped steel plate 3 has an arc-shaped structure. The strong spring 7 is connected between the reinforcing part 303 and the third inclined surface 105. The reinforcing part 303 is located on the side of the arc-shaped steel plate 3 near the top of the main body 1, increasing the thickness of the reinforcing part 303. The interior of the reinforcing part 303 has a triangular hollow structure. At the same time, the interior of the mounting cavity 11 near the third inclined surface 105 has a triangular structure. The stability of the triangle is used to strengthen the overall structural strength. The reinforcing part 303 reduces the distance between itself and the top of the main body 1, thereby limiting the rotation angle of the arc-shaped steel plate 3. Both ends of the arc-shaped steel plate 3 are rounded corner surfaces 302, which can better transition.

[0055] In actual use, the first inclined plane 101 is oriented towards the oncoming vehicle, and multiple spikes 14 are driven into the ground to fix the main body 1 to the ground, such as... Figure 10 As shown, the vehicle rushes towards the main body 1 from direction A. Guided by the first inclined plane 101, the vehicle will not directly collide with the main body 1, but will move diagonally upwards along direction B. The force applied in direction F is insufficient to move the main body 1 due to the obstruction of the spikes 14, as the spikes 14 are embedded in the ground and the vehicle does not directly impact it. The impact occurs differently depending on the vehicle speed; the following is a classification and description of different vehicle speeds:

[0056] When a collision occurs at a relatively slow speed, the vehicle moves slowly along direction B onto the first inclined plane 101 and then along direction C to the inner arc surface of the arc-shaped steel plate 3. The reinforcing part 303 applies a small pressure to the strong spring 7 in direction E. At this time, the degree of extension and contraction of the strong spring 7 is small. Under the action of the vehicle's own braking and the elasticity of the strong spring 7, the vehicle can be effectively stopped from continuing to move forward. After releasing the accelerator and brake, the vehicle will reverse and gradually stabilize, which can stop the vehicle from continuing to move forward at a relatively slow speed and effectively protect the safety of passengers.

[0057] When a vehicle is traveling too fast or experiences a brake malfunction and impact, the vehicle moves quickly along direction B to the first inclined plane 101, and then quickly moves along direction C to the inner arc surface of the arc-shaped steel plate 3. The reinforcing part 303 applies a large pressure to the strong spring 7 in direction E, resulting in a large degree of extension and contraction of the strong spring 7. Furthermore, the end of the arc-shaped steel plate 3 near the positioning shaft 301 tilts upward along direction D. As the front of the vehicle continues to move forward, the tilted part of the arc-shaped steel plate 3 will push against the chassis and move upward, causing the front of the vehicle to flip along the inner arc surface of the arc-shaped steel plate 3. This causes the vehicle, which is traveling too fast or has brake malfunction, to flip over on the side closest to the first inclined plane 101. After flipping over, the vehicle cannot continue to move, effectively preventing the vehicle from causing a larger traffic accident due to traveling too fast or having brake malfunction. Moreover, the close-range flipping causes less injury to the passengers on the vehicle, protecting their lives. The vehicle wear and tear is also lower compared to a direct impact, reducing the passengers' property loss.

[0058] Specifically, the buffer mechanism includes multiple strong springs 7, one side of each of the multiple strong springs 7 is fixedly connected to the third inclined surface 105, and the other side of each of the multiple strong springs 7 is fixedly connected to the reinforcing part 303.

[0059] In a specific embodiment of the present invention, the strong spring 7 has high-performance elasticity and can resist greater pressure. The strong spring 7 is evenly distributed between the third inclined surface 105 and the reinforcing part 303. When pressure is applied to the reinforcing part 303, the strong spring 7 can evenly distribute the pressure and effectively reduce the impact force when the car crashes through elastic extension and contraction.

[0060] Specifically, the lifting mechanism includes:

[0061] Frame 19 is fixedly connected to the upper inner wall of the main body 1 and is located on the upper side of the chassis 15;

[0062] The lead screw body 20 is rotatably connected between the inner walls of the frame 19. It consists of two opposing lead screws, one end of which passes through the frame 19 and is fixedly connected to the mating part 21.

[0063] There are two lead screw sleeves 25, which are threaded to the circumferential surface of the corresponding lead screw.

[0064] There are two limit rods 28, both of which are fixedly connected to the inner wall of the frame 19 and are located on both sides of the lead screw body 20.

[0065] The linkage assembly consists of four sets, each located between the chassis 15 and the frame 19. Each set is connected to one of the four corners of the chassis 15 to ensure stable lifting and lowering of the chassis 15. Each linkage assembly includes a straight rod 26, an upper hinge shaft 27, a linkage rod 29, and a lower hinge shaft 30. The upper hinge shaft 27 is slidably connected to the surface of the limiting rod 28. The straight rod 26 is fixedly connected between the upper hinge shaft 27 and the adjacent lead screw sleeve 25. The lower hinge shaft 30 is fixedly connected to the upper end of the chassis 15. One end of the linkage rod 29 is rotatably connected to the upper hinge shaft 27, and the other end of the linkage rod 29 is rotatably connected to the lower hinge shaft 30.

[0066] The drive assembly is located at the docking part 21 and is connected to the docking part 21 to drive the docking part 21 to rotate, thereby controlling the lifting and lowering of the roller 16. The drive assembly includes a drive shaft 22, a docking pin 23 and a turntable 24. Side sealing plates 8 are fixedly connected to both sides of the main body 1. The drive shaft 22 is rotatably connected to the side sealing plate 8 near the docking part 21 and extends outward. The docking pin 23 is fixedly connected to one end of the drive shaft 22 and can be detachably connected inside the docking pin 23. The turntable 24 is fixedly connected to the other end of the drive shaft 22.

[0067] In specific embodiments of the present invention, such as Figure 6 The frame 19 is fixed to the upper inner wall of the main body 1 by bolts. The main body 1 has a frame structure. The chassis 15 is located on the lower side of the frame 19, and the turntable 24 is located on the outer side of the main body 1. The mating pin 23 is inserted into the mating part 21. In use, the turntable 24 is rotated from the outside. The turntable 24 drives the drive shaft 22 to rotate, and the drive shaft 22 drives the mating pin 23 to rotate. Then, through the mating part 21, the lead screw body 20 is rotated. The lead screw body 20 is composed of two opposing lead screws, causing the two lead screw sleeves 25 to move in opposite directions. Under the linkage of the straight rod 26, the two upper hinge shafts 27 located on the same side move in opposite directions, which in turn causes the linkage rod 29 to shift. The lower hinge shaft 30 is close to the four sides of the chassis 15. At the corners, the chassis 15 can be raised and lowered smoothly, and finally the rollers 16 at the four corners are raised and lowered. For the sturdiness of the main body 1 structure, most of the main body 1 structure is made of metal, making it difficult to move the main body 1. When it is necessary to move the main body 1, control the rollers 16 to move downwards, so that the rollers 16 move to the lower side of the main body 1. At this time, the main body 1 can be moved directly, or it can be moved by traction equipment such as the tractor. The position can be moved at any time, saving time and effort. When it is necessary to stop, control the rollers 16 to move upwards, so that the rollers 16 retract into the main body 1, and the bottom of the main body 1 directly contacts the ground, increasing the contact area with the ground and effectively increasing the friction, so that the main body 1 is placed stably on the ground.

[0068] Preferably, both sides of the frame 19 are provided with sliding grooves 31, and the straight rod 26 passes through the sliding grooves 31 and extends outward to restrict the movement of the straight rod 26 and increase the stability of the movement of the straight rod 26.

[0069] Specifically, a plane 102 is provided near the second inclined surface 104 of the main body 1, and a plurality of positioning holes 13 are provided at the upper end of the plane 102, and a spike 14 is inserted into each positioning hole 13.

[0070] In a specific embodiment of the present invention, the positioning hole 13 is located on one side of the second inclined surface 104. During highway construction, which often involves working on the ground, the spike 14 can be driven into the ground to make the main body 1 more stable and enhance its impact resistance.

[0071] Specifically, a solar panel 10 is fixedly connected to the second inclined surface 104, an installation cavity 11 is provided inside the spike 14, a storage battery 12 is fixedly connected inside the installation cavity 11, a long rod 5 is fixedly connected to the top of the second inclined surface 104, a warning light 6 is fixedly connected to the upper end of the long rod 5, and the warning light 6 is electrically connected to the storage battery 12.

[0072] In a specific embodiment of the present invention, the warning light 6 serves as a warning light and can emit a flashing warning light, which is easily visible to people in low light conditions at night, thus reducing traffic accidents. The solar panel 10 and the battery 12 are rechargeable, which is convenient for use in the absence of power. The battery 12 is installed inside the mounting cavity 11, which is waterproof and rainproof, and will not be damaged.

[0073] Specifically, both ends of the chassis 15 are provided with hollow parts 1501, and axles 1502 are rotatably connected inside the two hollow parts 1501. Four rollers 16 are respectively fixedly connected to both ends of the axles 1502 on the same side. The upper end of the chassis 15 is provided with evenly distributed hollow parts 32.

[0074] In a specific embodiment of the present invention, the axle 1502 is the axis of the roller 16, and the hollow part 32 can reduce the mass of the chassis 15, facilitate assembly, and enhance the structural strength.

[0075] Specifically, the bottom of the main body 1 is provided with evenly distributed grooves 18, and reflective strips 9 are attached to the first inclined surface 101.

[0076] In a specific embodiment of the present invention, the groove 18 is provided at the bottom of the main body 1, which can increase the friction with the ground, and the reflective strip 9 plays a reflective role, which can reflect the vehicle's lighting light and play a warning role.

[0077] A method for using a collision avoidance device for highway construction includes the following steps:

[0078] S1. Place the main body 1 at a distance from the construction site, with the first inclined plane 101 facing the oncoming direction of the vehicle, and drive multiple spikes 14 into the ground to fix the main body 1 to the ground;

[0079] S2. When the vehicle is moving slowly and an impact occurs, the vehicle moves slowly upward along the first inclined plane 101 and moves to the inner arc surface of the arc steel plate 3. Under the pressure change of the arc steel plate 3, the extension and contraction of the strong spring 7 is small. Under the action of the vehicle's own braking and the elasticity of the strong spring 7, the vehicle can be effectively stopped from moving forward. After releasing the accelerator and brake, the vehicle will reverse and gradually stabilize.

[0080] S3. When a vehicle is traveling too fast or experiences a brake malfunction and an impact, the vehicle moves upwards along the first inclined plane 101 at a relatively high speed and quickly moves to the inner arc surface of the arc-shaped steel plate 3. Under the large pressure change of the arc-shaped steel plate 3, the extension and contraction deformation of the strong spring 7 is large, and the end of the arc-shaped steel plate 3 near the positioning shaft 301 is raised. As the front of the vehicle continues to be raised forward, the part will push against the chassis and move upwards. The front of the vehicle will be flipped along the inner arc surface of the arc-shaped steel plate 3, causing the vehicle traveling too fast or experiencing a brake malfunction to flip over on the side near the first inclined plane 101. After the vehicle flips over, it cannot continue to move, effectively preventing the vehicle traveling too fast or experiencing a brake malfunction from causing a larger traffic accident. Moreover, the close-range flipping causes less injury to the passengers on the vehicle, protecting the lives of the passengers. The wear and tear on the vehicle is lower compared to direct impact damage, reducing the property loss of the passengers.

[0081] S4. As the construction progresses or is completed, the main body 1 needs to be moved. When the main body 1 needs to be moved, the spike 14 is separated from the ground, and then the turntable 24 is rotated to drive the docking part 21 to rotate. The docking part 21 drives the lead screw body 20 to rotate. The lead screw body 20 drives the two lead screw sleeves 25 to move in opposite directions, thereby driving the upper hinge shaft 27 located on the same side to move in opposite directions. Under the linkage of the linkage rod 29, the chassis 15 gradually moves downward, and finally drives part of the roller 16 to move to the lower side of the main body 1.

3. A method for using a collision avoidance device for highway construction, characterized in that, The application of the anti-collision device for highway construction as described in claim 2 includes the following steps: S1. Place the main body (1) at a distance from the construction site, with the first inclined plane (101) facing the oncoming direction of the vehicle, and drive multiple spikes (14) into the ground to fix the main body (1) to the ground; S2. When the vehicle is moving slowly and an impact occurs, the vehicle moves slowly upward along the first inclined plane (101) and moves to the inner arc surface of the arc steel plate (3). Under the pressure change of the arc steel plate (3), the extension and contraction of the strong spring (7) is small. Under the action of the vehicle's own braking and the elasticity of the strong spring (7), the vehicle can be effectively stopped from moving forward. After releasing the accelerator and the brake, the vehicle will move backward and gradually become stable. S3. When the vehicle is traveling too fast or the brakes fail and an impact occurs, the vehicle moves upward along the first inclined plane (101) at a relatively high speed and quickly moves to the inner arc surface of the arc steel plate (3). Under the large pressure change of the arc steel plate (3), the extension and contraction of the strong spring (7) is large, and the end of the arc steel plate (3) near the positioning shaft (301) is raised. As the front of the car continues to be raised, the part will push against the chassis and move upward. The front of the car will be flipped along the inner arc surface of the arc steel plate (3), causing the vehicle traveling too fast or the brakes to flip on the side near the first inclined plane (101). After the vehicle flips, it cannot continue to move, effectively preventing the vehicle traveling too fast or the brakes from causing a larger traffic accident. Moreover, the close-range flipping causes less harm to the passengers on the vehicle, protecting the safety of the passengers. The wear and tear of the vehicle is lower than that of a direct impact, reducing the property loss of the passengers. S4. As the construction progresses or is completed, the main body (1) needs to be moved. When the main body (1) needs to be moved, the spike (14) is separated from the ground. Then, the turntable (24) is rotated to drive the docking part (21) to rotate. The docking part (21) drives the screw body (20) to rotate. The screw body (20) drives the two screw sleeves (25) to move in opposite directions, thereby driving the upper hinge shaft (27) located on the same side to move in opposite directions. Under the linkage of the linkage rod (29), the chassis (15) gradually moves downward, and finally drives part of the roller (16) to move to the lower side of the main body (1). At this time, the main body (1) can be moved directly to the destination.
