Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1, 2, 3 and 4, the road traffic height limiting frame comprises a limiting plate 4 and two supports 1, wherein the cross section of the limiting plate 4 is V-shaped, and an included angle between two side plates of the limiting plate 4 and the horizontal plane is 15-45 degrees. The bottom of limiting plate 4 is provided with recess 5. The inside transverse connection of recess 5 has pivot 7, and the both sides of recess 5 all are fixed with pivot mounting bracket 8, and the both ends of pivot 7 are installed on pivot mounting bracket 8. A plurality of buffer wheels 6 are embedded outside the rotating shaft 7, and are used for buffering the friction force generated when the vehicle is collided and converting the sliding friction force into the rolling friction force.
The both ends of limiting plate 4 all are connected with dead lever 12, and the other end of dead lever 12 is connected with slider 11. Limiting plate mounting frames 2 are arranged on two sides of the limiting plate 4, the limiting plate mounting frames 2 are fixed on the support 1, and fixing blocks 3 are connected between the support 1 and the limiting plate mounting frames 2 and fixed through the fixing blocks 3. The inside of limiting plate mounting bracket 2 is provided with cavity 9, and slider 11 embedding is in the inside of cavity 9, and the inside embedding of cavity 9 has spring 10, and spring 10 is located the upside of slider 11, and one side that is close to limiting plate 4 of cavity 9 is provided with spout 13, and dead lever 12 passes the inside of spout 13, dead lever 12 and spout 13 sliding connection. The bottom of the buffer wheel 6 is lower than the bottom of the fixing rod 12. When the vehicle top collides with the limiting plate 4, because the included angle between the two side plates of the limiting plate 4 and the horizontal plane is 15-45 degrees, the force of the vehicle top to the limiting plate 4 collision surface can be divided into components in the vertical direction and the horizontal direction, the force in the horizontal direction is balanced by the counterforce of the chute 13 to the fixing rod 12, and the force in the vertical direction pushes the limiting plate 4, the slider 11 moves upwards, the spring 10 contracts at the moment, the buffer wheel 6 contacts with the vehicle top when the limiting plate 4 moves to a certain height, and the sliding friction force is converted into rolling friction force, so that the friction with the vehicle is reduced, the bottom of the buffer wheel 6 is lower than the bottom of the fixing rod 12, and the vehicle avoids the contact with the fixing rod 12. The diameter of the roller 6 can be set properly to meet the requirements of smoother contact and smaller resistance of the vehicle with the roller 6. The pressure switch 14 is arranged on the lower side of the fixed rod 12, the pressure switch 14 is installed on the limiting plate installation frame 2, the fixed rod 12 is pressed on the pressure switch 14, the limiting plate 4 is jacked up when impact occurs, the fixed rod 12 is separated from the pressure switch 14 at the moment, and the pressure switch 14 triggers the camera installed on the rear side of the height limiting frame to take a picture and take a license plate.
When the vehicle top bumps with limiting plate 4, will promote limiting plate 4, slider 11 upward movement, spring 10 shrink this moment, buffer wheel 6 and vehicle top contact when limiting plate 4 moves a take the altitude, through turning into rolling frictional force with sliding frictional force to reduce the friction with the vehicle, the bottom of buffer wheel 6 is less than the bottom of dead lever 12, therefore the vehicle has avoided the contact with dead lever 12. The pressure switch 14 is arranged on the lower side of the fixed rod 12, the pressure switch 14 is installed on the limiting plate installation frame 2, the fixed rod 12 is pressed on the pressure switch 14, the limiting plate 4 is jacked up when impact occurs, the fixed rod 12 is separated from the pressure switch 14 at the moment, and the pressure switch 14 triggers the camera installed on the rear side of the height limiting frame to take a picture and take a license plate. When the vehicle is impacted, the top of the vehicle has obvious impact feeling, so that a driver can conveniently perceive the impact feeling. This height limiter protects the limiting plate 4 from damage in the event of a crash, and in addition, causes little damage to the vehicle itself. The road traffic height limiting frame is long in service cycle and high in safety.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
