Example 1:
as shown in fig. 1 to 5, for convenience of description in the present invention, a direction of the guard rail parallel to the road surface is defined as a longitudinal direction, and a direction of the guard rail perpendicular to the road surface is defined as a lateral direction in the following description. The invention provides an anti-collision damping system for a highway guardrail, which comprises a guardrail 1 and a base 2, wherein the base 2 comprises a supporting seat 3, the guardrail 1 comprises a transverse anti-collision damping system 20, and the transverse anti-collision damping system 20 comprises an anti-collision plate 6, a rubber sleeve 8, a telescopic rod 5, a sliding block 4 and a transverse spring 7; the outer side of the guardrail 1 is connected with an outer side anti-collision plate 6 through a sliding block 4 and an expansion rod 5, the anti-collision plate 6 is provided with a vertical fold structure 18, the fold structure 18 can be in various structural forms, and can be a U-shaped fold structure 18 or a V-shaped fold surface or a polygonal fold surface. The outer side of the anti-collision plate 6 is sleeved with a rubber sleeve 8, the rubber sleeve 8 has good elasticity and impact resistance, and the connection mode of the rubber sleeve 8 and the anti-collision plate 6 can be bonding, screw connection and the like. A plurality of transverse springs 7 are arranged on the inner side of the anti-collision plate 6 and between the telescopic rods 5, and at least 2 telescopic rods 5 are arranged; in this embodiment, the number of the telescopic rods 5 is 6, and the telescopic rods 5 comprise telescopic sections 501 and fixed sections 502.
The longitudinal sides of the supporting seat 3 are provided with baffles 15, the transverse sides of the supporting seat 3 are provided with slide rails 11, the sliding block 4 is matched with the slide rails 11 and slides on the slide rails 11, and one longitudinal side of the sliding block 4 is provided with a first longitudinal spring 12 and is connected with the baffles 15; the slide rail 11 is provided with a stopper 110 at a position corresponding to two ends of the slide block 4; the baffle 15, the first longitudinal spring 12, the slide rail 11, the stopper 110 and the slide block 4 form a longitudinal anti-collision damping system 10; the lateral elastic protection mode is triggered when the impact force experienced is small and mainly a lateral impact force 21, or when the vehicle 19 strikes the guard rail 1 in a vertical direction.
Further, the stopper 110 comprises a stopper spring 111 and a stopper 112; the limiting groove 113, the limiting block 112 sets up limiting guide edge 114, and slider guide edge 400 is set up in the slider 4 and the limiting guide edge 114 matching position of limiting block 112. When the longitudinal impact force 22 is received, if the impact force is smaller, the sliding block 4 cannot move longitudinally due to the limiting function of the limiting block 112; when the longitudinal impact force 22 is large, the sliding block 4 will conduct the impact force to the limiting guide edge 114 of the limiting block 112, and the limiting block 112 will compress the limiting spring 111 to move vertically and finally be pressed under the sliding block 4.
Further, in the transverse elastic protection mode, the anti-collision plate 6, the rubber sleeve 8 and the transverse spring 7 are elastically deformed in the transverse direction, and the stopper 110 limits the transverse movement of the sliding block 4 in the sliding rail 11.
Further, a first warning device 17 is mounted at the top end of the sliding block 4, the first warning device 17 is connected with a transverse touch button 14 through a lead 9, and the transverse touch button 14 is arranged at the joint of the transverse spring 7 and the sliding block 4.
Further, first warning device 17 contains bee calling organ, alarm lamp, GPS signal transmitter and solar battery, 4 tops of slider lay solar cell panel and with solar battery electric connection. The transverse touch button 14 is compressed by the transverse spring 7 to trigger the first warning device 17 to give an alarm to warn other vehicles of traffic accidents and to raise the driver's vigilance so as to avoid rear-end collision, and simultaneously, the signal is sent to a road administration control center through a GPS signal transmitter.
It will be appreciated by those skilled in the art that due to the inertia of the vehicle 19 traveling in the longitudinal direction of the roadway, typically, when the vehicle 19 strikes the guardrail 1, the impact force in the transverse direction is small, and the impact force in the longitudinal direction is large, but when the vehicle 19 strikes the guardrail 1 at different angles after a car accident, it may also be the case that the vehicle strikes the guardrail in the approximately vertical direction, and the longitudinal impact force 22 is almost zero, but there is still a certain transverse impact force 21, and then the transverse impact force 21 mainly impacts the guardrail 1.
5-6, in the transverse direction elastic protection mode, the detailed description is subjected to a smaller impact force, when both the longitudinal and transverse impact forces are smaller; or the impact force is mainly a lateral impact force 21, in the extreme case when the vehicle 19 strikes the guardrail 1 vertically, the lateral elastic protection mode will be triggered, which is described by taking the vehicle 19 striking the guardrail 1 vertically as an example. The vehicle 19 contacts with the rubber sleeve 8 on the surface of the anti-collision plate 6 at first, the rubber sleeve 8 is buffered, deformed and compressed, the rubber sleeve 8 absorbs part of the impact force, and transmits part of the impact force to the vertical corrugated structure 18 in a diffusion mode, the anti-collision plate 6 absorbs part of the impact energy through the elastic deformation of the vertical corrugated structure 18, and transmits the rest impact force to the transverse spring 7 on the inner side of the anti-collision plate 6, the transverse spring 7 further absorbs the energy through the elastic deformation, in the process, the telescopic section 501 of the telescopic rod 5 can stretch along with the transverse spring 7, the fixing section 502 of the telescopic rod 5 can play a role of guiding and limiting, so that the transverse springs 7 deform uniformly and absorb the impact force, at the moment, because the transverse impact force 21 is mainly transverse, the impact force in a longitudinal mode can be almost ignored, and under the limiting effect of the limiter 110 on the slide rail 11, the guard rail 1 does not move in the longitudinal direction. After the vehicle has been put aside, guardrail 1's horizontal spring 7, anticollision board 6, telescopic link 5 and rubber sleeve 8 automatic recovery original state, consequently, horizontal spring 7, anticollision board 6, telescopic link 5 and rubber sleeve 8 form horizontal crashproof shock mitigation system 20 that slows down the impact force at many levels together, and personnel in the protection vehicle avoid appearing reverse impact force, cause the injured phenomenon to appear, guarantee people's life safety, also protected the guardrail simultaneously, avoid carrying out repair work. In this process, since the vehicle 19 strikes the guard rail 1 in the vertical direction, as shown in fig. 5, the elastically deformed guard rail 1 can be automatically restored from the compressed state to the original state (shown in fig. 2), defining this process as a lateral elastic protection mode.
As shown in fig. 6, assuming that the impact force at the time of the collision of the vehicle 19 is small, both the longitudinal impact force 22 and the lateral impact force 21 are small, the impact process of the lateral impact force 21 is similar to that described above when the guardrail 1 is hit in the approximately vertical direction; in the longitudinal direction, because of the existence of the smaller longitudinal impact force 22, the longitudinal impact force 22 is transmitted to the slide rail 11 through the slider 4, but the longitudinal impact force 22 is absorbed by the stopper 110 under the limiting action of the stopper 112 of the stopper 110 on the slide rail 11.
In the transverse elastic protection mode, when the transverse spring 7 is compressed in the collision process, the transverse spring 7 presses the transverse touch button 14, and the first warning device 17 gives an alarm. When the crash panel 6 automatically returns to the original state after the vehicle 19 is removed, the transverse spring 7 also returns to the original state, the transverse spring 7 leaves the transverse touch button 14, and the first warning device 17 stops giving the alarm. The alarm information sent by the first warning device 17 can remind other vehicles of traffic accidents and the driver of improving the vigilance so as to avoid rear-end collision. Meanwhile, the first warning device 17 sends out warning information through a wireless signal, the GPS signal transmitter sends out a GPS signal, and the road administration center can judge the position of a traffic accident in the first time by identifying the information sent out by the first warning device 17, can pre-judge the damage condition of the guardrail and the occurrence of a lighter traffic accident and carry out corresponding emergency treatment.
