In view of the above problems, an object of the present invention is to provide a liftable deceleration strip set, which can adjust the degree of bumping according to the speed of a passing vehicle, so that a slow vehicle can pass through the set smoothly, and a high vehicle can be subjected to severe bumping.
The technical scheme adopted by the invention for realizing the technical purpose is as follows: the lifting deceleration strip group comprises a strip-shaped square deep groove and a square shallow groove which are arranged on a road surface, wherein the square shallow groove is positioned on one side where a vehicle comes; a first deceleration strip capable of moving in the vertical direction is arranged in the square shallow groove, and the first deceleration strip is in airtight fit with the square shallow groove; a second deceleration strip capable of moving in the vertical direction is arranged in the square deep groove; a pipeline communicated with the square deep groove and the square shallow groove is arranged below the square deep groove, wherein the length of the vertical section below the square deep groove is greater than the depth of the square deep groove; a piston is arranged in the vertical section of the pipeline and is connected with the second deceleration strip through a piston rod; a pipeline between the piston and the first deceleration strip is filled with liquid; a fixed partition plate is further arranged in a pipeline between the piston and the first deceleration strip, a small hole and a one-way valve pointing to the second deceleration strip from the first deceleration strip are formed in the partition plate; the mass of the second deceleration strip is larger than that of the first deceleration strip, so that when the deceleration strip set is under no external force, the second deceleration strip can naturally sink to the bottom, and meanwhile, the first deceleration strip is jacked up under the action of liquid pressure, so that the deceleration strip set is in a first limit state; when the first deceleration strip is pressed down and bottom-contacted under the action of external force, the piston rises under the action of hydraulic pressure and drives the second deceleration strip to rise out of the square deep groove completely to form an obstacle, and at the moment, the deceleration strip group is in a second limit state.
Preferably, one to three fixed speed reduction belts are arranged between the first speed reduction belt and the second speed reduction belt, so that the vehicle keeps low speed in the area continuously, and the height of the second speed reduction belt is two to three times of that of the fixed speed reduction belts.
Preferably, two to four groups of support structures formed by the piston, the piston rod and the vertical portion of the pipeline and arranged below the second deceleration strip are uniformly distributed along the extending direction of the second deceleration strip, so that good support performance for the second deceleration strip is obtained.
The invention has the beneficial effects that: the deceleration strip group is in a first limit state when no external force acts on the deceleration strip group, the second deceleration strip is completely sunk into the square deep groove under the action of gravity, and the first deceleration strip is jacked up to be raised on the ground under the action of liquid pressure; when a vehicle passes through the deceleration strip group, the vehicle firstly passes through and presses the first deceleration strip, and the first deceleration strip is pressed into the square shallow groove while being subjected to small bump; at the moment, the liquid in the pipeline rapidly flows to the side of the piston through the one-way valve under the action of pressure, and pushes the piston and drives the second deceleration strip to rise out of the square deep groove; on the way that the vehicle leaves the first speed bump to go to the second speed bump, as the liquid in the pipeline can only slowly flow from the piston side to the first speed bump side through the small hole, the second speed bump slowly sinks under the action of gravity; if the vehicle is running slowly, when it reaches the second speed reduction belt, the vehicle will not be greatly bumped when passing because the second speed reduction belt sinks for enough time and is at a lower height or even completely sinks into the groove; and if the vehicle speed is higher and the time for reaching the second deceleration strip is shorter, the second deceleration strip is at a higher height, so that the passing vehicle is violently bumped, the passing vehicle is forced to slow down to smoothly pass through the deceleration strip, and meanwhile, the deceleration strip group cannot cause great influence on the low-speed vehicle.
