[0003] At present, the speed bumps laid on the road are all in a fixed state. The original design of the speed bumps is to reduce the speed of the vehicle. When the speed of the vehicle is already very slow, the speed bumps at this time lose their original meaning and reduce the The belt will also produce bumps, and it is easy to scratch the vehicle with a lower chassis; there are many disadvantages

Embodiment Construction
[0028] The self-lifting deceleration belt used in the present invention adopts hydraulic control to lift the deceleration belt. When the vehicle passes at a high speed per hour, the contact time between the vehicle and the pressure plate is short and the kinetic energy of the vehicle itself is relatively large. The pressure exerted by the pressure-bearing plate is relatively large and the speed of the pressure-bearing plate descends quickly; when the vehicle passes at a low speed or slowly, the contact time between the vehicle and the pressure-bearing plate is long and the kinetic energy of the vehicle itself is relatively small. The pressure exerted by the pressure plate is relatively small and the pressure plate obtains a relatively small descending speed; the displacement generated by the different speeds of the pressure plate is used to sense the difference, and the movement area of the pressure plate in the vertical direction is controlled. Based on this The principle is...

The present invention discloses a hydraulic pressure control type vertical pressing self-lifting speed bump. A closed water storage tank and a plurality of jacking devices are installed between a baseplate and the bottom surface of a bearing plate, the water storage tank communicates to a tap water pipe, and the water storage tank is connected to one jacking device through an inflowing passageway and a drainage passageway; the jacking devices comprise cylinders, pistons slidably matched with the cylinders and capable of sliding in the vertical direction, and jacking rods connected with the upper end surfaces of the pistons, the cylinders are internally sleeved with jacking springs used for upwards jacking the pistons, and the upper end surfaces of the jacking rods are abutted with the lower end surface of the bearing plate; the inflowing passageway and the drainage passageway communicate to inner cavities of the cylinders of the jacking devices, a check valve a for controlling water in the water storage tank to flow to the cylinders is provided on the inflowing passageway, and a check valve b for controlling water in the cylinders to flow to the water storage tank is provided on the drainage passageway; and valves for controlling the flow of water are also provided on the inflowing passageway and the drainage passageway.
Description
technical field [0001] The invention relates to a road deceleration belt, in particular to a lifting type deceleration belt. Background technique [0002] The deceleration belt is the road belt that reduces the speed of the vehicle. It is placed on the required road section to reduce the speed of passing vehicles. It can cause large bumps to the vehicles passing at high speed and cause certain damage to the shock absorption of the vehicle. The resistance generated by it can be reduced. Speed: With the development of the economy, the number of vehicles is rising in a straight line. In order to restrain the speed of vehicles and protect the safety of pedestrians, the number of speed bumps laid on the road is also increasing. [0003] At present, the speed bumps laid on the road are all in a fixed state. The original design of the speed bumps is to reduce the speed of the vehicle. When the speed of the vehicle is already very slow, the speed bumps at this time lose their origin...
