Dynamic lifting platform 1 and each component being connected with lifting platform 1 rise or fall simultaneously, complete the liter synchronous with charging basket 3 of lifting platform 1
Drop operation.
After predetermined altitude is reached, first handle 11 is rotated, positive stop lug boss 12 is made to be contacted with rotating turret 10, is only rotated at this time
Frame 10 is connected with the 3rd gear 7 through bolt 9, starts motor 14, through the first drive gear 15, first gear 5 and second gear 6
Transmission, charging basket 3 can carry out independent descending motion or rise resetting movement, lifting platform 1 will not be had an impact, and then can be with
Realize the circulation material conveying operation of charging basket 3；And at this time due to the self-locking between 2 and the 4th gear 8 of leading screw, lifting platform 1 is reliably
Stop without falling.
As emergency preplan, make power-driven system can not normal work when running into the fortuitous events such as power failure or motor damage
When making, pressing rotation second handle 18 makes shaft 17 be connected with the second drive gear 16 through spline 21, rotates second handle 18,
Second drive gear 16 rotates simultaneously through shaft 17 with second handle, and the 3rd gear 7 being meshed with the second drive gear 16 produces
Raw rotate simultaneously drives the 4th gear 8 to rotate, the lifting platform 1 so as to the lifting for controlling lifting platform 1 or after the connection of bolt 9 with
Charging basket 3 lifts simultaneously, and staff is allow to return to ground safely, eliminates safety hazards to a certain extent.
Clever structure of the present invention, simple operation, materials are few, it is simple to build, and a dynamical system is only needed to can be realized and is applied
The simultaneously or independently elevating control of work platform and material transferring, convenient for the transmission of construction material；It can using the self-lock mechanism of leading screw
Operation platform is made reliably to stop at an arbitrary position, practicability is good, safe, without being equipped with individual locking system；It is recyclable
The charging basket of lifting not only instead of individual material transmission system, saves construction cost, while improves the biography of material
Some can be also transmitted to ground in time using rear remaining material and made proper arrangements, both saved on platform by defeated efficiency
Occupied space, and will not make some materials that can not use when putting or expose to the sun and rain long etc..
In addition, the present invention is provided with the second drive gear and second handle as stand-by power unit, it is unexpected disconnected meeting with
When electricity or power damage, construction personnel can control second handle to carry out descending operation manually, not only can effective guarantee constructor
The safety of member, but also material is quickly recycled, avoids material from inadvertently falling off the security risk of generation in High Altitude Platform.
