Abstract

A rocker arm wheel type multilevel cushioning fender consists of an old tyre 1, a wheel hub pipe 2, a through-going shaft 3, a rocker arm 4, a pipe chute 5, a core barrel 6 (the lower end of 6 is injected and fixed in a concrete base) which is of a shaft used for passing through the pipe chute 5, that are utilized in the cushioning fender after being replaced, as well as an elevator boom pipe 8, a suspension rope 9 and a heavy punch 10. A backrest 7 and a plurality of supporting tubes of the backrest are used for reinforcing the pipe chute 5 and ensuring the pipe chute not to be knocked down by a motor car. Rocker arm wheels which are composed by five old tyres can rotate freely; when the rocker arm wheels are knocked by a motor car out of control, the elasticity of the old tyre 1 and theroller guide action in the autorotation are utilized; the rocker arm wheel type multilevel device constitutes array in a protective guard by the road, and the rocker arm bears the action of restriction and damping (buffer, power absorbing and conceding) of the heavy punch and the old tyre groups in the multilevel array mutually transfer collision level by level, finally, the passages in the motorcar out of control are safely brought back the accurate travelling route under the guide action of the roller.

Description

Swinging arm wheeled type multi-stage cushioning guard fence

Technical field

The invention belongs to mechanical field, is a kind of swinging arm wheeled type multi-stage cushioning guard fence.

Background technology

Online some startling title: example: elegant highway is reflected to Wen Zhou in 213 national highway Dujiang weir, " valley of death "---Sichuan ... being steep hills on one side, Yi Bian be the Ming River that billows, is Aba state the only way which must be passed into ... truck, truck are in the majority ...Chongqing and for example, the descending 1km bend of sky way yellow sand mouth place, South Mountain ... almost all there was vehicle to fall down the precipice in nearly 2 years in every month ... be called " it is curved to fall the precipice ".It will be argued that motherland's highway that builds up monutainous regions in development is difficult heavy, temporary for the moment deficiency needs each citizen to have positive phychology in arms and goes to manage as far as possible, goes to reduce or the transport solution accident takes place with few method of spending.

Summary of the invention

The object of the invention: make descending zig zag, the cliffside of mountain region speedway or the ice and snow frost is often arranged or the highway section of mountain mist, the safety device that the protection automobile alleviates accident, avoids casualties are set.

Technical scheme of the present invention is: comprise the rocking arm wheel carrier that many railing forms are arranged, this rocking arm wheel carrier comprises used car wheel, wheel hub pipe, runs through axle, rocking arm, inclined tube, core pipe, backrest, weighing arm pipe, hoist cable and weight, cross out three rocking arms in the left side of inclined tube, the outer end of every rocking arm all is welded with the vertical tube of one section weak point, the center line of these three sections vertical tubes keeps same axis, and the lower end of next section vertical tube cover is welded with a nut; Each this crate wheel all is connected with the wheel hub pipe by the weldering flange, the wheel hub pipe of five this crate wheels is packed between three described vertical tubes, insert from the top down again and run through axle, and it is fastening to screw this screw thread and nut of lower end that runs through axle, and then five these crates are taken turns and can both be separately freely rotated running through on the axle; Pass the core pipe in the described inclined tube, the lower end of this core pipe is cast in the concrete base; Side at this inclined tube is provided with backrest, also is connected with the weighing arm pipe in a side of this inclined tube, is connected with weight by hoist cable on the top of this weighing arm pipe, and this weight is confined in the breach on the steep cliff at highway edge loosely.

Advantage of the present invention is: 1, except steel pipe should be used the cathodic anti-corrosion processing of ocean steamer new standard, other does not all calculate costly material, and bring more valuable safety for automobile, special bus, Sight Seeing Bus, make personnel's safety probably, vehicle can be not badly damaged; 2, used car is taken turns the device of changing a social system swinging arm wheeled type multi-stage cushioning, energy-absorbing, having the guide effect of roller, can make car out of control return the right way (special road surface at ice, snow, frost and water).3, as long as live in the weldering of the upper end of the upper end of running through axle and core pipe, in general, the thief is difficult to dismounting and steals.Otherwise, must install intelligent alarm system additional.

The specific embodiment

Referring to Fig. 1, the rocking arm wheel carrier by: used car wheel 1, wheel hub pipe 2, run through axle 3, Rocker arm 4, inclined tube 5, core pipe 6, backrest 7 (stay tube, hoop), weighing arm pipe 8 (three compositions), hoist cable 9, weight 10 and form.Used car takes turns 1 by the autotyre casing of scrapping, the interior foam mold pressing casting mold tire 1b that makes with reclaimed rubber that enriches, and the inner tube of a tyre of replacement inflation makes to maintain certain impact resilience; Every used car wheel through the transformation of the way can both freely rotate, when take charge, hitting used car in the direction of arrows took turns 1 o'clock, (1) elasticity of used car wheel and guide effect with roller, the multi-buffer effect of the rocking arm wheel carrier A of many railing forms arrangements is arranged again, make automobile slow down gradually, be revert on the safe road surface under reaction and the guide effect guiding and travel; (2) by the curved array of many rocking arm wheel carrier A shown in Figure 3, have the multistage energy-absorbing function of keeping out: the collision of automobile out of control was taken turns 1 o'clock to the used car of certain frame rocking arm wheel carrier A wherein, the component that collides is through Rocker arm 4, make inclined tube 5 on the rise along core pipe 6 (lower end is cast in the concrete base), this rising component is absorbed (energy-absorbing function) by weight 10, promoting Rocker arm 4 simultaneously rotates, cause used car wheel 1 (5 Geju City wheel) to bump against on the used car wheel 1 on the rocking arm wheel carrier A on contiguous right side, under inertia of the used car on this right side wheel (static inertia) and its weight effect, also can absorb a part of Impact energy, simultaneously, each is organized used car wheel and also can go up or the like along with rocking arm bumps against more the used car wheel of right; Because the weight of every rocking arm wheel carrier A all is confined in the breach on the steep cliff at highway edge loosely, so when each frame rocking arm wheel carrier A rotates, make weight tiltedly be pulled to lifting by weighing arm pipe 8, hoist cable 9---absorb impact energy, because of the effect of inclined tube 5, also make the weight castering action when shaking again.The other effect of inclined tube: (a) make and reduce shear stress when being subjected to vehicle impact on the road surface concrete base of core pipe 6; (b) because weighing arm pipe 8 moment maximums are in the minimum radius of gyration one side of inclined tube 5, so can keep used car wheel 1, Rocker arm 4 can align highway bend radius direction automatically at ordinary times.

Referring to Fig. 2, cross out three Rocker arm 4s in the left side of inclined tube 5, the outer end of every Rocker arm 4 all is welded with the vertical tube 4a of one section weak point, and the center line of these three sections vertical tube 4a keeps same axis, and the lower end of next section vertical tube 4a cover is welded with a nut 4b; When 5 Geju City wheels (through repacking) are put between three vertical tube 4a as figure, insert from the top down again and run through axle 3, and it is fastening to screw screw thread and the nut 4b of the lower end of running through axle 3, then 5 Geju City wheels 1 can both be separately freely rotate running through on spools 3.

The weldering flange 1c of used

car wheel

1 and 2 welding of wheel hub pipe, weldering flange 1c and old steel ring 1a rivet, and are the flexible liner of the replacement inflatable inner tube that forms of foam reclaimed rubber proplasm in the old cover tire that used car is taken turns.Weight Suo Yi is with glass fiber rope (ageing-resistant, be difficult for causing that the thief steals); Weight is that stone is processed into or cement prefab.
