Description

Highway waveform guardrail railing panel end cut-preventing device Technical Field The utility model relates to the technical field of road guardrails, in particular to a road waveform guardrail board end cutting-preventing device. Background The corrugated guardrail is a combined corrugated plate movable steel guardrail for the opening of a central separation zone of a highway, and consists of two corrugated steel guardrail plates and two upright posts fixedly clamped between the two corrugated steel guardrail plates, wherein the two upright posts are fixedly clamped between the two corrugated steel guardrail plates, and play a role in isolation and protection when the highway operates normally, and meanwhile, the corrugated guardrail corresponds to guardrail belts on the outer side of the highway, is neat and uniform, and is attractive and matched. The waveform guardrail end is sharp steel sheet direct exposure in the external world, and the vehicle is with the time of small angle or frontal striking, and end steel sheet probably invades the carriage inside like the cutting edge, causes passenger puncture injury, in order to reduce above-mentioned problem to appear, then the waveform anticollision end adopts crashproof fence to buckle to form the end often, and passes through a plurality of bolt fixed connection with the support column. The end is rigidly connected with the support column only through the anti-collision fence, so that the energy absorbing element is absent during collision, impact energy cannot be effectively dispersed through material deformation, and the end is easy to directly shear and break and penetrate into a carriage. Disclosure of utility model In order to overcome the defects of the prior art, the utility model provides a highway waveform guardrail plate end head anti-cutting device which comprises a plurality of upright posts which are uniformly arranged, wherein the upright posts are arranged in two rows in parallel, waveform guardrail plates are uniformly distributed beside each row of upright posts, the waveform guardrail plates are fixedly connected with the upright posts through bracket components, movable end heads are sleeved outside the two waveform guardrail plates, movable sliding grooves for sliding the waveform guardrail are formed in inner cavities of the movable end heads, two oppositely arranged waist-shaped grooves are formed in the movable end heads in a penetrating mode, the upright posts at the end parts penetrate through the movable end heads through the waist-shaped grooves and are connected with the movable end heads in a sliding mode, and the movable end heads are connected with the upright posts through energy absorption components. In order to achieve the above purpose, when the vehicle impacts the movable end at a small angle or in the front, the movable end is pushed to move, the movement of the movable end is guided and limited through the cooperation of the waist-shaped groove and the upright post, meanwhile, in the moving process of the movable end, the energy absorbing component plays a role in buffering, the energy absorbing component deforms, kinetic energy generated when the vehicle is in an out-of-control impact is absorbed, the deceleration of the impacting vehicle is reduced, and the possibility that the movable end is directly sheared and broken and penetrates into a carriage to cut and destroy the vehicle body is reduced. Further, the bracket assembly comprises two brackets arranged between two columns of upright posts, the two brackets are arranged oppositely, a connecting sleeve ring fixedly connected with the upright posts is nested outside the upright posts, four uniformly arranged connecting plates are integrated on the circumference outer wall of the connecting sleeve ring, two connecting plates positioned on the outer side are fixedly connected with adjacent wave-shaped guardrail plates, and two connecting plates positioned on the inner side are fixedly connected with the brackets. Further, the energy-absorbing subassembly is including fixing the first ear seat in both sides about the bracket, four all articulate on the first ear seat and be connected with the back bumper bar, each the wave form guardrail inboard all is fixed with two second ear seats that are located first ear seat side, each the second ear seat is high with adjacent first ear seat etc. the one end that first ear seat was kept away from to the back bumper bar is connected with the second ear seat is articulated, each still articulated on the second ear seat are connected with earlier bumper bar, the groove top and the tank bottom of movable chute all are fixed with two third ear seats, the one end that second ear seat was kept away from to earlier bumper bar extends to in the third ear seat and is connected with the third ear seat is articulated. Further, the two waveform guardrail plate ends and the two bracket ends are fixedly connected through a crash cushion, t
