a flexible high-pressure oil pipe is connected between the first cylinder body and the second cylinder body on the same side, one end, communicated with the first cylinder body, of the flexible high-pressure oil pipe is located on the front side of the first cylinder body, one end, communicated with the second cylinder body, of the flexible high-pressure oil pipe is located on the front side of the second cylinder body, the first piston cylinder is communicated with the second piston cylinder through the flexible high-pressure oil pipe, and hydraulic oil is filled in a space between a first piston inside the first cylinder body and a first rod seat, in the flexible high-pressure oil pipe and in a space, far away from one side of the second piston rod, of a second piston inside the second piston cylinder.
By adopting the technical scheme, the protection devices are symmetrically paved and installed along the two sides of the road, on one side, the bottom plate and the ground are fixed in a conventional mode, and the protection devices are uniformly spliced and paved to form a sidewalk on the bridge;
initially, the panel is in a horizontal state, the second piston is positioned at the front end of the second piston cylinder, and hydraulic oil in the second piston cylinder is temporarily stored in the first piston cylinder;
when a vehicle collides to the roadside, a part of the vehicle body is pressed on the panel, the weight of the vehicle body acts on the panel, most of impact energy on the vehicle acts on the guardrail, the guardrail can gradually move forwards under the action of collision and simultaneously can drive the two first pistons to move forwards through the two first piston rods, and as the space from the first piston to the rear end of the first cylinder body is a closed space, negative pressure can be formed in the space from the first piston to the rear end of the first cylinder body when the first piston moves forwards, and the guardrail can bear resistance when moving forwards, so that the forward movement time of the guardrail can be prolonged, and the time of the impact force of the vehicle acting on the guardrail can be prolonged, so that the vehicle can be protected by buffering;
when the first piston moves forwards, hydraulic oil in the first piston cylinder is extruded to the second piston cylinder through the flexible high-pressure oil pipe, the hydraulic oil entering the second piston cylinder can push the second piston, the second piston is matched with the top body through the second piston rod to push the panel upwards, the first cylinder body is hinged with the bottom plate through the first hinge base, the panel can turn upwards by taking the first hinge base as a rotating shaft, and because part of the weight of the vehicle body is applied to the panel, the panel can be subjected to resistance caused by the weight of the vehicle body, so that the forward movement time of the guardrail can be further prolonged, and the vehicle is further protected in a buffering mode;
the panel can drive the vehicle to incline upwards in the overturning process, so that the vehicle has a tendency of climbing upwards, the forward impact force of the vehicle can be dispersed, and the forward impact force of the vehicle is further reduced;
the larger the impact force of the vehicle on the guardrail is, the longer the distance that the guardrail drives the first piston to move forwards is, and the stronger the negative pressure action from the first piston to the rear end of the first cylinder body is, so that the intensity of the negative pressure action can be automatically adjusted according to the impact force of the vehicle;
the larger the impact force of the vehicle on the guardrail is, the longer the distance of the guardrail moving forwards is, the larger the volume of the vehicle pressed on the panel is, the larger the gravity borne by the panel is, and the larger the overturning resistance of the panel is along with the increase of the gravity, so that the overturning resistance strength of the panel can be automatically adjusted according to the impact force of the vehicle;
the larger the impact force of the vehicle on the guardrail is, the longer the forward movement distance of the first piston is, the more the hydraulic oil enters the second piston cylinder, the larger the panel overturning angle is, the more the impact force of the vehicle is dispersed, and thus the dispersion strength of the vehicle impact force can be automatically adjusted according to the impact force of the vehicle;
through foretell three-layer buffering protection, when the vehicle strikeed the guardrail, the impact force of vehicle striking guardrail can be dispersed gradually and absorbed, avoids taking place rigid collision between vehicle and the guardrail, and then reduces the damage to the vehicle to promote the protectiveness to personnel in the car.
Further inject, first cylinder body front end still is equipped with the third cylinder, and third cylinder sliding connection has the third piston, and third piston front end is equipped with the third cylinder pole, and third cylinder front side fixedly connected with third rod base, the third cylinder pole run through the third rod base and with the sealed sliding connection of third rod base, two third cylinder pole front ends all with guardrail fixed connection.
