[0029] Figure 1 It is a structural schematic diagram of the present invention. As shown in the figure, a highway reconstruction and expansion construction area safety active protection device in this embodiment includes a vehicle introduction component and a vehicle control component;
[0030] The vehicle introduction component includes an introduction channel 002 set at a set position, and the introduction channel 002 has an introduction slope inclined upward from rear to front; the slope of the introduction slope does not exceed 3°, and the slope in this solution is 3°, which is conducive to the vehicle 001 being smoothly introduced into the vehicle control component.
[0031] In this solution, a prefabricated stand is provided to form an import channel 002, and an import slope is formed on the top surface of the stand. When in use, the prefabricated stand only needs to be shifted and fixed to a designated position. The operation is convenient and has a wide range of applications. Of course, the import channel 002 can also be built and used as it is or preset at a designated position, which will not be repeated here.
[0032] The vehicle control component includes a roller 003 arranged on the front side of the introduction slope, the front is the forward direction of the vehicle 001, and the rear is opposite to the front direction, the roller 003 is driven to rotate around its own central axis, and the bottom end of the roller 003 has a height difference with the set position, so as to facilitate the self-rotation of the roller 003, and is not interfered by the environment and other factors, and the central axis of the roller 003 is perpendicular to the slope length direction of the introduction slope; so that the wheel axis of the vehicle 001 entering the vehicle control component is roughly parallel to the central axis of the roller 003, which is suitable for slope sections and complex turning sections, and can limit the wheel and rotate driven by the rotation of the wheel; wherein, the roller 003 can be a full-length cylindrical tube structure or a polyhedral tube structure, and the roller 003 can also be a plurality of segment structures that are coaxially assembled in a coherent and non-interfering manner, so as to meet the purpose of the rotating body driven to rotate by the wheel, and to achieve the purpose of retaining the vehicle 001, which will not be repeated here;
[0033] There are a plurality of rollers 003, the central axes of the plurality of rollers 003 are parallel, and the plurality of rollers 003 are arranged at set intervals; the number of rollers 003 and the intervals between the rollers 003 are increased or decreased according to the application scenario and requirements. When the rear wheel of the vehicle 001 that has mistakenly entered enters the vehicle control component, the wheels of the vehicle 001 turn forward, and since the rollers 003 of the control component are all in a non-locked state, the rollers 003 move in the opposite direction of the vehicle 001, and the vehicle 001 keeps idling on the rollers 003 of the control component and will not enter forward again, which can realize the active control of the vehicle 001 that has mistakenly entered the highway reconstruction and expansion area, and can ensure the safety in front of the construction.
[0034] The active safety protection device for highway reconstruction and expansion construction areas also includes a braking component, which is used to brake the roller 003 to prevent the rotation of the roller 003, so as to facilitate the vehicle 001 to drive out of the vehicle control component. The braking component includes sleepers or wedges or other braking equipment or structures, etc., which can realize the function of braking the roller 003. It is not shown in the figure and will not be described here. After the accident of accidental entry is handled, when the vehicle 001 that accidentally breaks into the vehicle needs to leave the vehicle control component of the device, it only needs to lock the rollers 003 in the vehicle control component, and then the vehicle 001 can leave the control area.
[0035] In the present solution, the roller 003 is a full-length cylindrical structure, and the braking assembly includes sleepers; the above structure is easy to obtain and inexpensive, and can be widely promoted and applied. The cylindrical structure of the roller 003 can further reduce the friction between the tire and the roller 003, and can better control the vehicle 001 within the specified area through the vehicle control assembly. The sleepers are lighter and have the characteristics of being easy to obtain, easy to use and easy to operate.
[0036] In this embodiment, the roller 003 is supported at a set position by a vibration reduction assembly;
[0037] The vibration reduction assembly includes a base 01, a connecting member and a first resistance member 02, the roller 003 is driven to rotate around its own central axis and is arranged on the connecting member, and the connecting member is installed on the base 01 through the first resistance member 02;
[0038] The base 01 is used to support the first connecting member at a set position, and the first resistance member 02 has an elastic force that makes the base 01 and the connecting member approach or move away, and the direction of the elastic force is parallel to the vertical direction. By setting the first resistance member 02 with elastic force, the vehicle 001 can always be in a driving state of swinging up and down, raising its head and nodding its head in the area where the entire vehicle control component is set, and when the roller is continuously driven to rotate, the kinetic energy can be greatly consumed, and the vehicle 001 can be braked in time. Under the action of the elastic force, after the front wheel passes through the rear end roller 003, if the speed is too fast, the rear wheel will pass through the roller 003 again after it resets, which can also play the function of eliminating energy again; and if the whole vehicle is in a continuous climbing and upward posture after driving into the area where the vehicle control component is set, it can also reduce part of the kinetic energy and improve the braking ability of the vehicle 001; the first resistance member 02 can be an elastic member such as a spring or an elastic rubber strip or other elastic components, which is suitable for realizing the established energy reduction function, and will not be repeated here.
[0039] In this embodiment, the vibration reduction assembly further includes a second resistance member 03, which is arranged at the bottom of the first resistance member 02, and the connecting member has a supporting end 41, which is controlled to contact or release contact with the second resistance member 03, and the second resistance member 03 has a damping force that prevents the supporting end 41 from moving downward. The arrangement of the second resistance member 03 can again assist the first resistance member 02 in achieving the deceleration of the vehicle 001, and the damping force is used to prevent the first resistance member 02 from moving downward. At the same time, its own damping effect can also play a certain vibration reduction effect when under pressure, so that the kinetic energy of the vehicle 001 is attenuated again when it moves forward, which greatly improves the speed control ability of the vehicle 001, can brake the vehicle 001 more quickly and effectively, and has no destructive effect on the vehicle 001, and can achieve active braking of the vehicle 001 only through the structure, so that the vehicle 001 can be controlled more safely within the specified area; the second resistance member 03 can select a damping block or a damping device or a damper, etc., to achieve the established energy reduction function, which is not repeated here.
[0040] In this embodiment, the connecting member includes a connecting main shaft 42, and the roller 003 is driven to rotate on the connecting main shaft 42; a lubricating layer is provided between the roller 003 and the connecting main shaft 42, or a rotating member 05 is provided between the roller 003 and the connecting main shaft 42; in this scheme, a rotating member 05 is provided between the roller 003 and the connecting main shaft 42, and the rotating member 05 is a bearing, the connecting main shaft and the inner ring of the bearing are fixed, the roller and the outer ring of the bearing are fixed, and there are several bearings provided along the length of the connecting main shaft 42, and the bearings have sufficient rigidity and supporting capacity, and are more practical. Of course, the lubricating layer is also applicable to this scheme, and both can reduce the friction force and enable the roller 003 to be driven to rotate smoothly, which will not be repeated here.
[0041] In this embodiment, the connecting member also includes a force transmission block 43 fixed to the connecting main shaft 42. In this solution, the force transmission block 43 is located at the end of the connecting main shaft 42 and is in the shape of a rectangular cube. The force transmission block 43 has a functional rod 44 protruding downward, and the functional rod 44 is a columnar structure. The first resistance member 02 includes a compression spring sleeved on the functional rod 44, and the compression spring is located between the bottom surface of the force transmission block 43 and the top surface of the base 01; the compression spring has the characteristics of high elasticity and high supporting capacity, and has a long service life. The compression spring is selected from any one of the existing technologies and is applicable to this solution, which will not be repeated here.
[0042] In this embodiment, the base 01 has an assembly chamber 45 for guiding the functional rod 44, and the second resistance member 03 includes a damper, which is arranged at the bottom of the assembly chamber 45. The bottom end of the functional rod 44 extends into the assembly chamber 45, that is, the bottom end of the functional rod 44 serves as the supporting end 41, and there is a set distance between the bottom end of the functional rod 44 and the force-bearing end of the damper. The damping force direction of the damper is consistent with the elastic force direction of the compression spring. The damper is selected from any one of the existing technologies and is applicable to this scheme, which will not be repeated here.
[0043] In this embodiment, the base 01 is in a frustum shape, and the assembly chamber 45 is located at the center of the frustum-shaped base 01. The assembly chamber 45 includes a guide channel for guiding the functional rod 44. The shape and size of the guide channel are consistent with the shape and size of the functional rod 44, which meets the preset guiding function, improves the operating stability and reliability of the mechanism, improves the service life, and can effectively reduce the driving kinetic energy of the vehicle 001. The damper is arranged at the bottom of the guide channel.
