Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described further.
As Figure 1-4, of the present utility model from walking and the traction walking switchable lifting working platform chassis of both of which, including underframe 01, it is assemblied in two on the downside of underframe 01 and drives deflecting roller 02 and two supporting rollers 03, two driving deflecting rollers 02 are ordered about to walk and ordered about by steering cylinder 22 by hydraulic motor 21 respectively and turn to, underframe 01 is equipped with the fork 31 that can swing to both sides (above-below direction shown in Fig. 2), two supporting rollers 03 save 32 downsides being assemblied in underframe through follow-up steering respectively, it is connected to steering link 33(referring to Fig. 7-8) between follow-up steering joint 32 and fork 31, underframe is provided with for retraining the restraining structure that fork swings.
When equipment is normal, being retrained fork by restraining structure makes fork not swing, namely supporting roller can not turn to, and supporting roller becomes directional wheel, now can by hydraulic motor with drive deflecting roller drive whole chassis move realization from walking, ordered about driving deflecting roller by steering cylinder and turn to；
When breaking down and cannot certainly walk in chassis, hydraulic motor, steering cylinder lose pressure at power failure state and automatically terminate power, deflecting roller is driven to automatically return to middle position, now release the constraint to fork, chassis is drawn by fork, fork can freely swing along with pull strength, and then order about supporting roller and turn to, it is possible to chassis is drawn walking and drags scene away from.
As the mode of immediate constraint fork, restraining structure is be located in fork and the pin rod on underframe.When being located in when pin rod on fork and underframe, fork can not be restrained relative to underframe swing, and when pulling down pin rod, fork can swing relative to underframe and be released from constraint, can draw chassis by fork.
In order to draw chassis, fork 31 is connected to the draw bar 34 spun upside down.Need to be overturn (referring to Fig. 1-2) by draw bar when drawing, it is not necessary to during traction, up and draw bar upset is retrained (referring to Fig. 3-4).Now, restraining structure is the deck 11 for retraining draw bar, deck includes one with uncovered groove portion and for closing uncovered upset pin 12, upset pin leaves uncovered can upset by draw bar flip out to groove portion or from groove portion, when by draw bar upset to groove portion, then upset pin upset is constrained on deck by draw bar to closing uncovered position.In order to shorten draw bar restrained time length, draw bar is formed by connecting by two sections of unidirectional-folding (be only capable of to a direction folding), will not bend voluntarily when launching traction, and the draw bar of unidirectional-folding can be connected by fast joint structure.
For the ease of assembling and making rational in infrastructure, underframe is provided with crane span structure 13, and two follow-up steerings joints rotate the two ends being assemblied in crane span structure respectively, and fork is assemblied on crane span structure by rotating shaft 35.Two drive the downside (referring to Fig. 5-6) that deflecting roller is assemblied in underframe respectively through driving knuckle 24；Driving and be connected to steering linkage 23 on knuckle, steering cylinder connects steering linkage and realizes driving turning to of knuckle；Hydraulic motor is fixed on driving knuckle；Hydraulic motor connects about position, free to rotate.
