Further specify through of the enforcement of a working cycle below the utility model.
The initial condition of platform 11: horizontal minimum altitude state, positive stop lug boss 16-1 and limiting stopper 7-1 on the back hinged-support 16 are in the applying restrained condition, and this moment, travel switch 18 was a normal open; Energized gets into parallel up-down pattern.Like Fig. 1, shown in Figure 3.
1), press lifting key: oil pump 30 starts, and oil cylinder 21 oil-feeds are suppressed, platform 11 parallel risings, and can being locked on the arbitrary setting operating altitude between minimum altitude to the maximum height through the insurance leg.
2), by parallel decline key: oil pump 30 starts to delay time then and stops; One section (for the cylinder release is prepared) → the 3rd electromagnetic valve 32 conducting of platform 11 parallel risings earlier; Forward and backward unlock cylinder conducting; Connect compressed gas source 31, forward and backward unlock cylinder flicks ratchet → the 3rd electromagnetic valve 32 of locking and opens, the 11 parallel declines of oil cylinder time-delay release oil return → platform.
In the parallel lifting process of platform, press locking key, the 3rd electromagnetic valve 32 turn-offs; First electromagnetic valve 27 is opened, cylinder cutout, oil cylinder 21 oil returns; Platform 11 descends by deadweight, and on the nigh ratchet of locking, platform 11 current height are locked the insurance leg to front slide; As will continue to go up and down, get final product release by parallel decline key.
The contact that platform 11 continues contact back, the bottom position limiting pile 7 end faces → travel switch 18 of decline → back hinged-support 16 begins bruising base 1, until breaking off travel switch 18, stops to descend; Platform 11 current states: its front end is a little less than horizontal minimum altitude, and this moment, travel switch 18 broke off, and the 3rd electromagnetic valve 32 turn-offs, second electromagnetic valve 30 continues conducting.
3), when the horizontal minimum altitude state of platform 11; By inclination decline key: first electromagnetic valve 27 is opened; Oil cylinder 21 release oil returns; Platform 11 is that center of turn tilts to descend with the back upward rotating shaft of back arm 12: position limiting pile 7 end faces slide backward the front arc of hinged-support 16 bottoms, back along the back, and the positive stop lug boss 16-1 on the back hinged-support 16 separates backward, the constraint of disengaging limiting stopper 7-1; Front arm 17 preceding go up rotating shaft in the oval slotted eye of preceding hinged-support 23 to front slide, preceding insurance leg 18 preceding ratchet 4 front ends neutral gear in slide extend, until the bottom of preceding hinged-support 23 contact front limit stake 2 end faces; Vehicle bridge 25 front ends land on the Self-carried type of platform 11, and platform 11 front ends tilt to drop to lowest order.Like Fig. 4, shown in 5.
4), press lifting key; First electromagnetic valve 27 is closed; 21 oil-feeds of oil pump 30 startup → oil cylinders suppress → and to go up rotating shaft with back arm 12 back be that center of turn tilts to rise to platform 11: and position limiting pile 7 end faces are to front slide along the back for the front arc of hinged-support 16 bottoms, back, and the positive stop lug boss 16-1 on the back hinged-support 16 fits forward; The preceding upward rotating shaft of front arm 17 is slided to the back upper place in the oval slotted eye of preceding hinged-support 23, again through the constraint of positioning plate 7-1 to the positive stop lug boss 16-1 of back hinged-support 16, until the rear end of withstanding oval slotted eye; Platform 11 changes parastate over to, returns to horizontal minimum altitude state, and travel switch 18 contacts reset, conducting, and platform 11 finishes tilt mode, gets back to initial condition.Like Fig. 1, shown in 3.
