Principle of work and working process:
Manual stair climbing vehicle is made up of separate car body mechanism and Climbing building device two large divisions.When upper going downstairs, Climbing building device and car body mechanism rapid abutting joint are installed, form overall cart for travelling up or down stairs.Lay down Climbing building device when level road, light walking, also can drive not to be separated with Climbing building device and advance.Both be applicable to disabled person oneself goes downstairs, also can other people have assisted downstairs.And to have in manned loading downstairs, and when level road several functions the same as common car.Wherein abutting joint and unloading process can be completed by people oneself by bus.
Time on needs downstairs, Climbing building device is arranged on below car body, opened lock locking mechanism 38, by pivoted arm pin 34 and pivoted arm 35, road wheel 36 is rotated the front to seat 1, namely road wheel 36 is front, climb building pawl 23 rear, meanwhile, regulate hand the angle of inclination of 8 adjustment backrests 2, when to floor conversion platform by arc chute radius stay 7 and backrest, the balance rollers 4 that backrest 2 rear portion is arranged can contact with floor levels, prevents hypsokinesis.The first step place of last layer can also be rolled in narrow and small stair case flat roof area, continue upstairs or go downstairs.Climb one-way rolling in building process and according to circumstances can postpone face step by car load at any time near step wall by hand push banister or with hand steered.Prevent from climbing building pawl to step on sky and fall.
As shown in Fig. 4 ~ 6, by level road State Transferring for after climbing building state, handle 30 gets to automatic position, handle 30 drives two-way ratchet 26 with hand, ratchet 25 to be engaged, thus be with screw shaft 10 to rotate by inner sleeve 31, screw shaft 10 passes through engaging and disengaging gear, gear mechanism and sprocket wheel link chain mechanism by transmission of power to power take-off shaft 22, climbs building pawl 23 rotate eventually through power take-off shaft 22 drive.Can realize driving Climbing building device and related car body entirety realizes upper downstairs walk wheel mechanism and being launched by pivoted arm 35 or packed up, and be regulated by backrest 2 and realize level road and climb building power and energy.Walk with road wheel 36 oneself that two hands rotate left and right wheels setting by taking people when level road, or other people push walking.Replace swinging handle 39 by two hands to start to climb building, now a control engaging and disengaging gear makes clutch friction plate 16 compress ratchet 15, reciprocally swinging handle 39, two-way ratchet 26 engages bidirectional ratchet 25 thus drives screw axial direction to rotate, realize drive climb building pawl 23 rotate climb building, ratchet 15 now and ratchet 14 ensure that screw shaft 10 only rotates to a direction.Time downstairs, handle 30 gets to manual gear, due to gravitate, climb building pawl 23 can automatically be rotated down, handle 39 now mainly realizes brake function, concrete, after handle 39 drives clutch nut 32 opposite spin, clutch friction plate 16 is separated with ratchet 15, ratchet 15 can relative to rotating freely with screw shaft 10, screw shaft 10 is not subject to the direction controlling of ratchet 15 and ratchet 14, now climb building pawl 23 drive screw shaft 10 opposite spin under gravity and start downstairs, when after next step, reverse operation handle 39 makes clutch friction plate 16 compress ratchet 15 again, now ratchet 15 and ratchet 14 task again, screw shaft 10 is stopped the rotation, thus Shi Pa building pawl 23 stops, when climbing building pawl 23 and being stuck on stair, now rotated a little downwards by another handle 39 Shi Pa building pawl 23, climb and after building pawl 23 rotates, just can again utilize the effect of gravity to go downstairs.
With reference to Fig. 8, at floor levels place, further backrest 2 can be regulated backward by backrest angle regulating mechanism.
When preparing to terminate to level road from level road, by Climbing building device and the rapid abutting joint dismounting of car body mechanism, level road is walked lighter upstairs or downstairs.Climbing building device and car body relatively independent, be beneficial to Function Extension and function and change.Manual drives can be changed into motor reducer according to different demand to drive, become electric stair climbing.
Or as shown in Figure 9, driver train is electric model, and driver train also can be the mechanism comprising self-locking speed-down machine 41 and motor 42, motor 42 output shaft connects the input end of self-locking speed-down 41, and the mouth of self-locking speed-down machine 41 connects power take-off shaft 22.
In addition, speed reduction gearing drive sprocket 19, chain 20 and can also be replaced with gear by movable sprocket 21.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
