Abstract

The invention relates to a rotary rod pressure spring type guide crash pad, which consists of a buffer head, frames, rotary rods, guide rails, side beams and a support frame, wherein a horizontal sliding groove is arranged in each frame; a spring and a sliding block are arranged in each horizontal sliding groove; pin joint boards are arranged at two ends of each rotary rod; the guide rails are arranged at the bottom; the buffer head is arranged at the front end; the support frame is arranged at the rear end; the frames are arranged between the buffer head and the support frame; the bottoms of the frames are movably connected with the guide rails; the frames can slide along the guide rails; the side beams are arranged at two sides of the frames; each rotary rod is slantly arranged between adjacent frames, one end of the rotary rod is connected with the sliding block in the horizontal sliding groove by a pin, and the other end of the rotary rod is connected with the pin joint board at the back of the horizontal sliding groove. When the rotary rod pressure spring type guide crash pad is used, the guide rails and the support frame are fixed to the ground, when a car impacts the crash pad from the front, the frames backwards slide along the guide rails, the rotary rods are compelled to push the sliding blocks to slide in the horizontal sliding grooves and compress the springs to work, and the collision energy is absorbed; when the car impacts the crash pad from the side face, the side beams are used for providing a guide function for the car, and the collision energy is absorbed.

Description

The swing arm compressed spring type bumper that can lead
Technical field
The present invention relates to public road traffic safety facilities field, particularly relate to a kind of swing arm compressed spring type bumper that can lead.
Background technology
Along with China's rapid development of economy, highway construction career development is rapid, meanwhile, serious accident but occurs again and again, analyzing main cause is because safety protection facility protective capacities is not enough or have security protection leak, last line of defense when safety protection facility occurs as traffic accident, plays a part very important to the order of severity of accident.Because shunting trigonum does not arrange effective energy-absorbing anti-collision facility, when vehicle collision waveform joist guard rail end head, likely there is guardrail board insertion car body, passenger is caused to mortal injury; If there is errant vehicle collision concrete guardrail triangle termination, may be because acceleration is too large, car body distortion seriously causes occupant injury.In the past, the protection method that take the dangerous triangle termination on most domestic highway was glass fiber reinforced plastic Sand Bucket, but this measure does not have the buffering energy-absorbing function to errant vehicle, and Sand Bucket is knocked away, and second accident very easily occurs, and causes car crash.
China had also developed some bumper structures that can lead in recent years, but these can lead, bumper is all that the mode that adopts the yield deformation of steel member to absorb collision energy designs substantially, this energy-absorbing mode is not only utilized the distortion energy-absorbing function of material completely, cause a large amount of waste of material, therefore, need a kind of energy-absorbing member of exploitation bumper structure that can reusablely lead badly, thereby save material usage, reduce cost and maintenance cost.
Summary of the invention
The object of this invention is to provide a kind of swing arm compressed spring type bumper that can lead, this bumper that can lead can effectively absorb collision energy, there is the features such as dependable performance, cost is low, I&M is easy, can be applied to the infrastructure construction fields such as highways and streets.
The swing arm compressed spring type of the present invention bumper that can lead, by buffer head, framework, swing arm, guide rail, curb girder, bracing frame composition, buffer head is placed in front end, bracing frame is placed in rear end, between framework is set, swing arm is set between framework, guide rail is placed in base of frame and is mutually flexibly connected, curb girder is placed in framework both sides, it is characterized in that: framework is provided with horizontal concrete chute, in horizontal concrete chute, establish spring and slide block, pin joint plate is established at swing arm two ends, swing arm is oblique to be placed between adjacent frame, slide block pin joint in one end and horizontal concrete chute, the pin joint plate pin joint at the other end and horizontal concrete chute back is fixed.
Described spring can be one of them or combination of helical spring, disk spring, ring spring, flat spring, leaf spring, rubber spring, air spring.
The cross sectional shape of described swing arm can be circle, rectangle, ellipse, flute profile, I-shaped wherein it
Described framework is made up of column, suspension column slide plate, horizontal concrete chute, spring, slide block, pin joint plate, perpendicular support and diagonal brace, the edge-on layout of horizontal concrete chute, and spring and slide block are placed in horizontal concrete chute, and pin joint plate is located at horizontal concrete chute back.
Described buffer head is hollow structure, and its cross sectional shape can be one of them or combination of rectangle, circle, trapezoidal, C shape.
Described guide rail is sliding groove structure.
Described curb girder can be one of them of channel-section steel, rectangular tube, pipe, two corrugated sheet, three corrugated sheets.

Detailed description of the invention
Now the invention will be further described by reference to the accompanying drawings.
As shown in Figures 1 to 8, the embodiment of the present invention comprises buffer head 1, framework 2, swing arm 3, curb girder 4, guide rail 5, bracing frame 6.Framework 2 is made up of column 7, horizontal concrete chute 8, spring 9, slide block 10, suspension column slide plate 11, pin joint plate 14, perpendicular support 12 and diagonal brace 13, horizontal concrete chute 8 lateral recumbent posture settings, spring 9 and slide block 10 are placed in horizontal concrete chute 8 inner ends successively, pin joint plate 14 is arranged at the back of horizontal concrete chute 8, and the two ends of swing arm 3 arrange respectively pin joint plate 14.When assembling, buffer head 1 is placed in front end, bracing frame 6 is placed in rear end, between framework 2 is set, swing arm 3 is oblique to be placed between adjacent framework 2, one end and slide block 10 pin joints, and on the other end and framework 2, the pin joint plate 14 at horizontal concrete chute 8 backs carries out pin joint and fixes, guide rail 5 is placed in framework 2 bottoms and is mutually flexibly connected, and curb girder 4 is placed in framework 2 both sides.When use, guide rail 5 and bracing frame 6 are fixed on road surface, in the time of vehicle frontal collision, framework 2 slides backward along guide rail 5, forces swing arm 3 to promote slide block 10 and does work in the interior slippage of horizontal concrete chute 8 Compress Spring 9, absorbs collision energy; In the time of vehicle side impact, curb girder 4, for vehicle provides guide function, absorbs collision energy.
