Detailed Embodiment

[0030] The following further describes the present utility model in conjunction with the drawings and embodiments.

[0031] In the specific implementation process, as Figure 1 - Figure 5As shown, the device is installed on the anti-collision vehicle 1 and includes an anti-collision body 10. One end of the anti-collision body 10 is detachably connected to an arc-shaped FRP grid 2. The FRP grid 2 includes an inner arc plate 30 and an outer arc plate 28. Between the inner arc plate 2 and the outer arc plate 28, a plurality of arc-shaped placement cavities 9 arranged along the arc length are separated by partition plates 29. In each arc-shaped placement cavity 9, a V-shaped structure reinforcing rib 3 is provided. The small end of the V-shaped structure reinforcing rib 3 is fixedly connected to the outer arc plate 28, and the large end is fixedly connected to the inner arc plate 30. On one side of the outer arc plate 28, a plurality of buffer components are provided. The plurality of buffer components are arranged along the arc length, and each buffer component corresponds to the position of the small end of the V-shaped structure reinforcing rib 3. Each buffer component is installed on the outer arc plate 28 of the FRP grid 2. The buffer component includes a hinge seat 5, a collision-proof plate 7, and two oppositely arranged dampers 4. The model of the damper 4 can be AC1005-2. The damper is an oil pressure buffer. Its working principle is that when an external force is applied to the axis, the piston moves inward with the axis, which will squeeze the hydraulic oil in the inner tube. The hydraulic oil needs to find a way to release the pressure due to being compressed. The hydraulic oil is forced to flow out through the tiny oil discharge holes on the piston. This process will generate resistance due to the aperture limitation, converting kinetic energy into heat energy, thus achieving the absorption of impact energy. At the same time as the oil is discharged, a part of the hydraulic oil may also flow back to the other side of the inner tube through the oil return hole. Such a cyclic flow further improves the efficiency of energy absorption. The generation of resistance can be adjusted according to different impact speeds to achieve the best buffering effect. When the impact force disappears, the built-in return spring starts to play a role, pushing the piston and the associated axis back to the initial position. During this process, the hydraulic oil flows back into the piston side from the oil storage chamber through the oil return path, preparing for the absorption of the next impact. One end of the hinge seat 5 is fixedly connected to the side wall of the collision-proof plate 7. The other end of the hinge seat 5 is hinged with two connecting rods 6. The two dampers 4 are both fixedly installed on the outer arc plate 28. The two connecting rods 6 are respectively connected to the two dampers 4. When the collision-proof plate 7 is impacted, the collision-proof plate 7 will squeeze the hinge seat 5. The hinge seat 5 drives the two connecting rods 6 to move. The angle between the two connecting rods 6 increases, and the ends of the connecting rods 6 squeeze the dampers 4 to achieve the purpose of buffering through the dampers 4. Polyurethane foam 8 is filled in the plurality of cavities 9. The polyurethane foam 8 has good compressibility, enhancing the anti-collision performance of the device;

[0032] The anti-collision body 10 is provided with FRP fillers 11 in a honeycomb structure. One end of the anti-collision body 10 is detachably connected to the FRP grid 2. A plurality of T-shaped grooves 12 are formed at one end of the anti-collision body 10. A plurality of T-shaped blocks 13 are fixedly connected to the inner arc plate 30. The plurality of T-shaped blocks 13 can be respectively inserted into the plurality of T-shaped grooves 12. The T-shaped blocks 13 and the T-shaped grooves 12 are snap-connected. The FRP grid 2 and the anti-collision body 10 are snap-connected through the mutual cooperation of the T-shaped grooves 12 and the T-shaped blocks 13, which is simple and fast to install, easy to replace, and has a low maintenance cost. Through the mutual cooperation of the anti-collision body 10 and the honeycomb FRP fillers 11, the mechanical advantages of the ductility of the metal and the high strength of the FRP are fully utilized, and the ability to resist deformation and the specific energy absorption in the collision are improved. In addition, the FRP structure is light in weight and high in strength, and the entire flexible anti-collision structure is lighter than the steel structure;

[0033] On one side of the anti-collision vehicle 1, a lifting and flipping device is installed. The lifting and flipping device includes a lifting mechanism and a flipping mechanism. The lifting mechanism is installed on the anti-collision vehicle 1, the flipping mechanism is installed on the lifting mechanism, and the anti-collision body 10 is connected to the flipping mechanism. The lifting mechanism includes two threaded rods (15) and two motors (16). The two threaded rods 15 are vertically supported on the upper and lower support plates 14 on the anti-collision vehicle 1 through bearings. A lifting seat 17 is in threaded fit with each threaded rod 15. A mounting frame 18 is fixedly connected to the two lifting seats 17. Each of the two threaded rods 15 is connected to a motor 16. The motor 16 is installed on the lower support plate 14. By driving the threaded rod 15 to rotate through the motor 16, the lifting seat 17 is driven to move. The flipping mechanism includes a pair of gear-rack mechanisms, two linear electric cylinders 23, and a rotating rod 19. The linear electric cylinders 23 are installed on the cylinder mounting seats 22 on the mounting frame 18. The linear electric cylinders 23 are connected to the racks 24 of the gear-rack mechanisms and are used to drive the racks 24 to move up and down. The two ends of the rotating rod 19 are supported on the mounting frame 18 through bearings and are respectively connected to the gears 25 of the gear-rack mechanisms. The rotating rod 19 is radially fixedly connected to the mounting plate 21 of the anti-collision body 10 through a connecting plate 20. By driving the gear-rack mechanism through the linear electric cylinder 23, the anti-collision body 10 is driven to flip. When the device is not needed, the motor 16 drives the threaded rod 15 to rotate, and the mounting frame 18 moves upward under the action of the two lifting seats 17. Then, the linear electric cylinder 23 drives the rack 24 to move downward. Since the rack 24 is engaged with the gear 25, when the rack 24 moves downward, the gear 25 rotates, so that the rotating rod 19 drives the connecting plate 20 and the mounting plate 21 to move, facilitating the flipping work of the anti-collision body. When the anti-collision body is flipped, the anti-collision body is in a horizontal state and is located on the anti-collision vehicle 1. A longitudinal plate 27 is fixedly connected to the two lifting seats 17 together. A buffer hydraulic cylinder 26 is horizontally arranged on the longitudinal plate 27. The buffer hydraulic cylinder 26 is a hydraulic cylinder buffer device arranged in the hydraulic cylinder. Due to the setting of this buffer device, even when an external force is applied to the hydraulic cylinder, the situation where the pressure is higher than the design strength of the hydraulic cylinder will not occur. In the hydraulic cylinder buffer device arranged in the hydraulic cylinder, the hydraulic cylinder includes a tube forming a collection chamber for hydraulic oil, a rod performing linear motion, a piston and an end flange fixed on the rod and separating the collection chamber of the tube. The hydraulic cylinder buffer device includes a buffer sleeve installed on the rod and close to the piston. If the piston approaches the rod-side end flange during the linear motion of the rod, a predetermined buffer pressure is generated in the rod-side chamber. It also includes an elastic body arranged on the buffer sleeve to prevent the piston from colliding with the rod-side end flange and absorb the impact through its elasticity. By setting the buffer hydraulic cylinder 26, when the anti-collision body flips, a certain buffering effect can be achieved on the anti-collision body.

[0034] The working principle provided by the present utility model is as follows: When the device is in use, if a vehicle impacts the anti-collision device, it will first impact the buffer component. When the anti-collision plate 7 is impacted, the anti-collision plate 7 will squeeze the hinge seat 5, and the hinge seat 5 drives the two connecting rods 6 to move. The angle between the two connecting rods 6 increases, and the end of the connecting rod 6 squeezes the damper 4 to achieve the purpose of buffering through the damper 4. In addition, in this device, the buffer component is fixedly connected to the outer arc plate 28 of the FRP grid 2, and the connection of the reinforcing rib 3 arranged in a V-shaped structure in the arc-shaped cavity 9 formed by the inner arc plate 30, the outer arc plate 28, and the spacer plate 29 on the FRP grid 2 corresponds. Therefore, through the reinforcing rib 3 arranged in a V-shaped structure, the firmness during the extrusion of the damper 4 and the FRP grid 2 is enhanced. Through the mutual cooperation of the FRP grid 2, the reinforcing rib 3, and the polyurethane foam 8 filled in each cavity 9, because the polyurethane foam 8 has good compressibility, after the vehicle impact causes damage, it is easy to repair and replace locally, greatly reducing the maintenance cost. When the device is not needed, the motor 16 drives the threaded rod 15 to rotate, and the mounting frame 18 moves upward under the action of the two lifting seats 17. Then, the electric cylinder 23 drives the rack 24 to move downward. Since the rack 24 meshes with the gear 25, when the rack 24 moves downward, the gear 25 rotates, so that the rotating rod 19 drives the connecting plate 20 and the mounting plate 21 to move, facilitating the flipping work of the anti-collision body. When the anti-collision body is flipped, the anti-collision body is in a horizontal state and is located on the anti-collision vehicle 1.

[0035] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present utility model by the same token.
