Working principle of the present invention is as follows:
Illustrate the working principle of the invention in conjunction with Fig. 1 to Fig. 9.Elastic boom unfolding mechanism of the invention is in when undeployed
Rounding state, as shown in figure 1 shown in C, the connecting spring clamp 21 of latter pulley mechanism is stuck in the card column of previous coaster,
Pulley mechanisms all in this way, which all link together, to be stored in slideway 2.16 both ends of upper tabletting of pulley mechanism are symmetrically installed with gold
Belong to rubber 19 and locking traveller 18, locking traveller 18 is connected through a screw thread and is fixed on 16 both ends of tabletting, and is fixed on lower sheeting
The hole of traveller seat 20 on 17 constitutes sliding pair, and 18 lower end of traveller is equipped with spring 25, when pulley mechanism is also unlocked, keeps
Upper tabletting 16 is in jack-up state.Because upper tabletting 16 is in jack-up state, it is mounted on tabletting on first pulley mechanism
The locking traveller 18 at 16 both ends stretches out 20 1 sections of traveller seat, and the locking traveller 18 of stretching is stuck in the limit bullet for being fixed on limited block 11
In spring clamp 27, thus first pulley mechanism is just in locked position and waits locking.
When expansion, the motor 8 that is fixed on slideway 2 connect by right-angle reduction device 9 with threaded post 15, threaded post 15 with consolidate
The thread bush 14 being scheduled on clamping sleeve 12 screws, so that clamping sleeve 12 be driven to move down, upper tabletting 16 is depressed, when upper tabletting
16 when being pressed down to commitment positions, and grab 24 is stuck on the boss of tabletting 16, and upper tabletting 16 and lower sheeting 17 are locked to one
Block, upper tabletting 16 and lower sheeting 17 are jointly clamped intermediate elastic boom 3 by metal-rubber 19, and it is heavy to lock traveller 18 at this time
To inside locking traveller 18, limited block 11 loses kinematic constraint to first pulley mechanism, and being achieved in coaster retaining mechanism will
Pulley mechanism is locked on elastic boom 3, and last motor 8 inverts, and driving clamping sleeve 12 resets.
After first pulley mechanism is locked on elastic boom 3, with flexing outward for elastic boom 3, because second
The connecting spring clamp 21 of pulley mechanism is stuck in the card column of first pulley mechanism, therefore second pulley mechanism is by first
Pulley mechanism is dragged to locked position, and subsequent all pulley mechanisms also move forward a parking stall, when second pulley mechanism moves
When moving locked position, because the traveller 18 of second pulley mechanism also stretches out 20 1 sections of traveller seat, limited block 11 hinders
Second pulley mechanism is pulled further along by first pulley mechanism, and first pulley mechanism continue to move along, card
Column will be detached from from the connecting spring clamp 21 of second pulley mechanism, it is thus achieved that point of front and back two pulleys mechanism
From when first pulley mechanism continues to move along, the film 6 and wirerope 5 being connected between two pulleys mechanism are gradually
Be tightened up, second pulley mechanism is locked into again on elastic boom 3 later, formed truss element, and so on will be until institute
There is truss element all until expansion, when last coaster is moved to locked position, the taper pin that is mounted on traveller seat 20
26 sell into the taper hole of limited block 11, realize being fixedly connected for entire film development agency and slideway 2, improved structure it is whole just
Degree.
