Detailed description of the invention
Wheel-chair lift of the present utility model (as shown in Figure 1, Figure 2).
Upper parallel swing arm (2) is connected by hinged with elevator permanent seat (8) and upright arm (4) respectively with lower parallel swing arm (3).Upset upper arm (11) is connected by hinged with upset underarm (12) and upright arm (4) respectively.Upset underarm (12) two ends are connected by hinging supporting shaft with upset upper arm (11) and platform (6) respectively.Upset roller (13) is enclosed within upset upper arm (11) with on the hinging supporting shaft (26) of upset underarm (12).Upright arm (4) is connected with the hinging supporting shaft (27) of platform (6) by upright arm (4) with platform (6).
Wheelchair rises from ground and process is into the car:
Lifting tables machine platform (6) is to the state (as Fig. 1) during ground, and now, rear plate washer (9) is in vertical position, and front baffle board (7) automatic turning is to opening position.Elevator landing (6) climbed up by wheelchair.Elevator is under the effect driving oil cylinder (1), upper parallel swing arm (2) and lower parallel swing arm (3) swing around elevator permanent seat (8) coercive mechanism, upright arm (4) is driven to rise, platform (6) synchronously rises, front baffle board (7) automatic turning is to vertical position, now, rear plate washer (9) is still in vertical position, prevents wheelchair from tumbling in uphill process.Under the effect driving oil cylinder (1), when lifting tables machine platform (6) continues to rise to vehicle floor height (as Fig. 8), rear plate washer (9) overturns under the driving of rear plate washer driver train (10), ride on the floor of vehicle, now, front baffle board (7) is still in vertical position.Wheelchair into the car.
Wheelchair enters elevator in car, and the process dropping to ground is:
Lifting tables machine platform (6) is to the state (as Figure 10) during vehicle floor height, and now, rear plate washer (9) rides on the floor of vehicle, and front baffle board (7) is in vertical position.Wheelchair enters platform (6), elevator is under the effect driving oil cylinder (1), upper parallel swing arm (2) and lower parallel swing arm (3) swing around elevator permanent seat (8) coercive mechanism, upright arm (4) is driven to decline, platform (6) synchronously declines, rear plate washer (9) turn to vertical position under the driving of rear plate washer driver train (10), now, front baffle board (7) is still in vertical position, prevents wheelchair from tumbling in decline process.Under the effect driving oil cylinder (1), platform (6) continues to drop to floor level (as Fig. 1), now, rear plate washer (9) is still in vertical position, front baffle board (7) is when platform (6) kiss the earth, and automatic turning is to open position.Now, wheelchair can be rolled to ground.
The lockable mechanism (as Fig. 5) of wheel-chair lift of the present utility model.
Snap close (22) is connected by hinging supporting shaft (23) with snap close adapter plate (16), snap close has a waist type groove (24), snap close adapter plate (16) has a locating dowel pin (15), locating dowel pin (15) is enclosed within snap close waist type groove (24) the inside, the anglec of rotation of restriction snap close (22), snap close adapter plate (16) is provided with an extension spring anchor shaft 2 (17), snap close (22) is provided with an extension spring anchor shaft 1 (19), in the middle of extension spring anchor shaft 2 (17) and extension spring anchor shaft 1 (19), a snap close extension spring (18) is installed, when snap close (22) is in open position and locking position, snap close extension spring (18) is worked, ensure that snap close (22) rests on open position or locking position (center of the hinging supporting shaft (23) of snap close (22) and snap close adapter plate (16) is crossed in snap close extension spring (18)).Snap close (22) is installed one handle (21), handled easily.Column (4) is fixed a gear shaft (20), and elevator is when to pack up, and snap close (22) is buckled on gear shaft (20).Gear shaft (20) also can be eccentric, to facilitate adjustment.
Platform from the process of the state (as Fig. 3) that the state (as Fig. 1) during ground rises to when to pack up is:
Lifting tables machine platform (6) is to the state (as Fig. 1) during ground, and under the effect driving oil cylinder (1), platform (6) synchronously rises to the state (as Figure 10) during vehicle floor height.Under the effect driving oil cylinder (1), platform (6) continues to rise to upset roller (13) simultaneously and contacts with edge under lower parallel swing arm (3).Under the effect driving oil cylinder (1), platform (6) is under the promotion of upset underarm (12), and the connecting hinge fulcrum (27) around upright arm (4) and platform (6) upwards overturns.Until platform (6) is vertical.Now, platform (6) upset puts in place, and in this process, snap close has 2 kinds of mode of operation.
Mode one: when snap close (22) is in locking position, in the process that platform (6) overturns, gear shaft (20) on upright arm (4) contacts (as Fig. 7) with the inclined-plane (28) of snap close (22), drive snap close (22) left-hand revolution together, after platform (6) upset puts in place, snap close (22) is under the pulling force effect of snap close extension spring (18), clickwise, is stuck on gear shaft (20);
Mode two (as Fig. 8): when snap close (22) is in open position, after platform (6) upset puts in place, hand pulls handle (21), by snap close (22) clickwise, is stuck on gear shaft (20);
The process that snap close unlocks is (as Fig. 9):
Hand pulls handle (21), by snap close (22) left-hand revolution, throw off gear shaft (20), and continuation rotation contacts to waist type groove (24) with locating dowel pin (15), now snap close extension spring (18) makes snap close (22) remain on open position, and locking is removed.
