The principle of work of utility model is as follows:
Wheelchair is got on the bus:
Lifting table 11 is in the ground location (see figure 2), and front apron 29 front ends bump ground, and front apron 29 rotates, and makes wheelchair can reach lifting table 11.Long drag-line 32 is pulled to back shield 30 and lifting table body 27 basic upright positions, prevents that wheelchair from rolling from lifting table 11 from the rear.
Wheelchair reaches and is parked in ground lifting table (11), by promoting switch, motor 15 work of Hydraulic Station, drive oil pump through control module 18 to oil cylinder 6 fuel feeding, oil cylinder stretches out, by the parallel-crank mechanism of forming by swivel mount 3, swing arm 5, plumbing arm 8 and strut bar 9 lifting table 11 is promoted (Fig. 2) from ground level, lifting table 11 front aproies 29 rotate under the torsion spring effect and reset, block wheelchair and roll down lifting table 11 from front end, (Fig. 1) travel switch action when lifting table 11 arrives the vehicle floor plane, lifting table 11 stops to rise automatically.Simultaneously, when lifting table 11 promoted, long drag-line 32 fluffed, and back shield 30 rotates under the effect of torsion spring, when lifting table 11 arrives the vehicle floor position, and back plate washer 30 and vehicle floor plane contact.
Wheelchair drives in the car, again by promoting switch, oil cylinder 6 continues to stretch out, the switching mechanism work of forming by upset strut 10, swing arm 5, plumbing arm 8, strut bar 9, lifting table 11 and oil cylinder 6, lifting table 11 is more than vehicle floor position (Fig. 1), and upset strut 10 can't compress, and upset strut 10 promotes the flip-arm 26 of lifting table 11, make lifting table 11 around plumbing arm 8 lower end jointed shaft rotations, thereby lifting table 11 is turned to the position (Fig. 3) perpendicular with the vehicle floor plane.Simultaneously, when lifting table 11 upsets, short drag-line 34 is under the driving of flip-arm 26, pulling back shield 30 rotates to lifting table body 27, fluffs with duration drag-line 32, but under the effect of spool 33, long drag-line 32 has certain expanding force all the time, curls to prevent long drag-line 32.When lifting table 11 was turned to the vehicle ground upright position, back plate washer 30 turned to lifting table body 27 and fits substantially.
By promoting switch, locking drives reducing motor 20 rotations, and driving gear 21 rotates synchronously, drive 22 rotations of two ring gears,, then drive screw rod 23 and shrink because the ring gear endoporus is threaded, thereby realize to remove locking, make swivel mount 3 can be relatively and fixed mount 1 rotate.
By promoting switch, the axle on the rotary drive motor 4 driven in rotation framves 3 makes swivel mount 3 turn 90 degrees (Fig. 3,4) around fixed mount 1 horizontal dextrorotation.
By promoting switch, locking drives reducing motor 20 rotations, driving gear 21 rotates synchronously, drives 22 rotations of two ring gears, because the ring gear endoporus is threaded, then driving screw rod 23 stretches out, screw rod 23 withstands swivel mount 3 sides, realizes swivel mount 3 relative fixed framves 1 locking, makes lifting table 11 be parked in the stowed position, thereby abdicate passage, make things convenient for other people and thing to get on or off the bus.
Under emergency condition, can adopt manual fuel pump 19 to oil cylinder 6 fuel feeding.Rotatable manual drives bar 24 unclamps or locking rotation lock locking mechanism.Because rotary drive motor 4 band power-transfer clutchs, available hand propelled lifting table 11 realizes that manually rotation drives.
Wheelchair is got off:
By the decline switch, locking drives reducing motor 20 rotations, and driving gear 21 rotates synchronously, drive 22 rotations of two ring gears,, then drive screw rod 23 and shrink because the ring gear endoporus is threaded, thereby realize removing locking, swivel mount 3 can be rotated by relative fixed frame 1.
By decline switch, the axle on the rotary drive motor 4 driven in rotation framves 3, make swivel mount 3 around fixed mount 1 horizontal left-hand revolution 90 degree (Fig. 3,4).
By the decline switch, locking drives reducing motor 20 rotations, driving gear 21 rotates synchronously, drive two ring gears 22) rotation, because the ring gear endoporus is threaded, then drives screw rod 23 and stretches out, screw rod 23 withstands swivel mount 3 back sides, realize swivel mount 3 relative fixed framves 1 locking, make lifting table 11 be parked in control position.
Again by the decline switch, 20 actions of hydraulic workstation 2 electromagnetic valves, because lifting table 11 deadweights make oil cylinder 6 to hydraulic workstation 2 oil extractions, lifting table 11 is from beginning turning with vehicle ground upright position (referring to Fig. 3), (referring to Fig. 1) travel switch action when lifting table 11 arrives the vehicle floor plane, lifting table 11 automatic stop motions.Simultaneously, when lifting table 11 upsets, back shield 30 is under the driving of torsion spring and short drag-line 34, and back shield 30 rotates, and when lifting table 11 was turned to the vehicle floor planimetric position, back plate washer 30 rotated and leans against (referring to Fig. 1) on the vehicle floor plane.
Wheelchair sails lifting table 11 in car, by the decline switch, 20 actions of hydraulic workstation electromagnetic valve, because gravity makes oil cylinder 6 to hydraulic workstation 2 oil extractions, under the effect of deadweight, lifting table 11 on even keels are dropped to ground (Fig. 2) from vehicle floor planimetric position (Fig. 1) by the parallel-crank mechanism of forming by swivel mount 3, swing arm 5, plumbing arm 8 and strut bar 9.Simultaneously, long drag-line 32 tensioners are pulled to back shield 30 and lifting table 11 basic upright positions, prevent that wheelchair from rolling from lifting table 11 from the rear.Front apron 29 front ends bump ground, and front baffle board 29 rotates, and makes wheelchair sail down lifting table 11 from lifting table 11 front ends.
Under emergency condition, rotatable manual drives bar 24 unclamps or locking rotation lock locking mechanism.Because rotary drive motor 4 band power-transfer clutchs, available hand propelled lifting table 11 realizes that manually rotation drives.Open the hand switch of electromagnetic valve 20 bands, lean on the deadweight of lifting table 11 to make oil cylinder 6 to hydraulic workstation 2 oil extractions, lifting table 11 is from overturning (Fig. 3) downwards to vehicle floor planimetric position (Fig. 1) with upright position, vehicle floor plane.Equally, the level of (Fig. 2) descends from the vehicle floor plane to ground location to realize lifting table 11 by deadweight.
