Description

Track traffic barrier free wheelchair fixer

Technical field

The present invention is applied to Vehicle Engineering, is used in the construction of guideway vehicle no-obstacle traffic, helps disadvantaged group to provide condition of going on a journey more easily, is specifically related to a kind of wheelchair fixer.

Background technology

At present, nearly more than 8,300 ten thousand disabled persons of China, relate to the population of 2.6 hundred million families.Meanwhile according to relevant data, China has 36 cities and is establishing urban track traffic, and wherein the planning in 28 cities has obtained the reply of State Council, and within 2009, to the year two thousand twenty, city rail increases revenue kilometres 6560Km newly, always reaches 7395Km.From above data analysis, in the today greatly developing track traffic, helping the disabled to walk out door, the pacing factor of the participation social activities of safety, equality, is that track traffic development especially will be considered to erect between the disabled and society one " bridge ".

In the city railway vehicle of existing home and abroad, wheelchair fixer is safety band type structure.Buenos Aires, ARG city A line railcar in the design process, owner requires in car, arrange wheelchair fixer, but not safety band type wheelchair fixer, and wheelchair fixer to meet disabled person by Self-operating can simple and fast complete steady job.For avoiding passenger to make due to the vibration of vehicle operating when using wheelchair fixer passenger along with the vibration generation movement of vehicle, thus cause Peril Incident, and consider safety, need to design the highly stable wheelchair fixer of a kind of fixed performance.

Summary of the invention

The object of this invention is to provide a kind of barrier free wheelchair fixer, easy to operate, safe and reliable, go on a journey to facilitate the disabled.

For achieving the above object, the invention provides a kind of track traffic barrier free wheelchair fixer, it is characterized in that: comprise adapter plate, angle steel, cover plate, supporting base, mount pad, plate switch, mobile locking switch, U-shaped axle, stage clip, torsion spring, jam plate, stud, adapter plate is fixedly connected with by gusset with angle steel, angle steel side parallel join cover plate and supporting seat, connection seat above angle steel, cover plate is that U-shaped opening is arranged on angle steel side outwardly, a U-shaped axle is established through cover plate upper surface, a plate switch is established above one of them long column of U-shaped axle, one end of plate switch is movably arranged on mount pad fixing above angle steel by bearing pin, in the part that U-shaped axial length post is positioned at U-shaped cover plate, surface cover has stage clip, the fulcrum that jam plate rotates as jam plate is connected above another short column of U-shaped axle, a stud is also established through cover plate in the side of U-shaped axle, and stud upper end is fixedly connected with jam plate through cover plate, and stud is provided with torsion spring, torsion spring upper end is fixedly connected with stud, and lower end is fixedly connected with cover plate.

Can move as required for convenience of wheelchair fixer, on angle steel, be socketed another angle bar, cover plate and supporting seat are fixed on the side of angle bar, mount pad is fixed on above angle bar, perforate above angle bar, hole internal fixtion one nut, nut thread connects mobile locking switch.

The present invention is by pressing down plate switch, jam plate is opened by the effect of U-shaped axle short column and stage clip, torsion spring, press after plate switch jam plate is opened and can unclamp plate switch, now U-shaped axle short column springs back to jam plate lower surface, and wheelchair wheel enters into supporting base region, enters always, until the hole on jam plate overlaps with U-shaped axle short column, now U-shaped axle short column is got back to above jam plate, makes wheelchair fixer arrive locking state, now fixes complete; When passenger getting off car, directly press plate switch, jam plate is opened, and wheel shifts out.This wheelchair fixer provides condition of going on a journey more easily to disadvantaged group, improves the safety of passenger, reliability, improves vehicle performance.Enable disabled person passenger oneself conveniently complete independently fixing operation, the family having freed upper limbs abled person accompanies and attends to, and decreases social cost.Compact conformation is reasonable, and anufacturability is good, simple, practical, has good promotional value and wide prospect market.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

Fig. 2 is the part sectional view of Fig. 1.

Detailed description of the invention

With reference to Fig. 1, Fig. 2,1, adapter plate; 2, gusset; 3, angle steel; 4, cover plate; 5, supporting base; 6, mount pad; 7, angle bar; 8, nut; 9, switch; 10, rubber pad; 11, bearing pin; 12, mobile locking switch; 13, U-shaped axle; 14, stage clip; 15, torsion spring; 16, jam plate; 17, stud; 18, axle opening circlip; 19,

Adapter plate 1, 3 pieces of gussets 2, angle steel 3 is welded and fixed together, three pieces of gusset accommodated side-by-side one sides are welded with adapter plate, another side welds with angle steel, another angle bar 7 is socketed on angle steel, cover plate 4 and supporting seat 5 are fixed on the side of angle bar, mount pad 6 is fixed on above angle bar, perforate above angle bar, hole internal fixtion one nut 8, nut thread connects mobile locking switch 12, cover plate 4 is arranged on angle iron side outwardly for U-shaped opening, a U-shaped axle 13 is established through cover plate upper surface, a plate switch 9 is established above one of them long column of U-shaped axle, one end of plate switch is movably arranged on mount pad fixing above angle bar by bearing pin 11, rubber pad 10 is provided with below plate switch 9, in the part that U-shaped axial length post is positioned at U-shaped cover plate, surface cover has stage clip 14, the fulcrum that jam plate 16 rotates as jam plate is connected above another short column of U-shaped axle, a stud 17 is also established through cover plate in the side of U-shaped axle, stud upper end is fixedly connected with jam plate 16 through cover plate 4, stud is provided with torsion spring 15, torsion spring upper end is fixedly connected with stud 17, lower end is fixedly connected with cover plate 4 by axle opening circlip 18.

Structure of the present invention is fixed in disabled person region set in vehicle by bolt.When passenger needs to use, after pressing plate switch 9, after U-shaped axle moves down the hole walking out jam plate 16, jam plate 16 unlocks to be opened, the wheel of wheelchair enters into supporting base 5 region, promotes jam plate 16 left-hand revolution and enters always, be limited in supporting base region until jam plate 16 is pushed to completely by the wheel of wheelchair, U-shaped axle rises and pins jam plate 16 under the effect of stage clip, fixing complete; When passenger getting off car, directly press plate switch 9, after U-shaped axle moves down the hole walking out jam plate 16, jam plate 16 is opened under the effect of torsion spring, and wheel shifts out.If passenger moves wheelchair and moves close to inconvenience during supporting base again, move by opening mobile locking switch 12 pairs of wheelchair fixers, thus actv. fixes wheelchair.
