Detailed description of the invention
A kind of lifting false work, comprises support body 1, fills electric block 2 on support body, and the lifting rope 3 that electric block drives is through being fixed on after assembly pulley and adhering on bracing frame 4 that assembly pulley top building is connected, and described assembly pulley is loaded on support body, the below of electric block; Described assembly pulley is made up of two pulleys, the fixed fixed pulley 5 of one of them pulley, and another pulley is movable pulley 6 moving up and down; The steel pipe guide rail being made up of the vertical seamless steel pipe 7 in two of front and back is set on support body, is adhering to the ring ring that on bracing frame, setting is made up of the non-linear arc wheel 8 in two groups of left and right, steel pipe guide rail is arranged in and ring ring, coordinates with ring ring.
Described movable pulley is fixedly connected with slide block 9 lower ends, and slide block is arranged in take-up housing 10, can slide up and down along the chute of take-up housing, and take-up housing is fixedly connected with support body; The upper end of slide block is connected with mobile stressed 11, and mobile stressed is connected with the lower end of push rod 12, and the upper end of push rod withstands on one end of linkage lever 13, and the other end of linkage lever is pressed on anti-falling lock 14; Described anti-falling lock comprises the pin 15 contacting with linkage lever 13, and pin is connected with platen 16, and platen is sleeved on fixed leg 17, can move up and down along fixed leg; Fixed leg is loaded on housing 18, and housing is fixed on support body; Housing and platen central authorities all arrange the medium pore that installs suspension rod 19, and at least two inclined holes 20 are set in housing, and the upper end of inclined hole communicates with the medium pore of housing, is placed with stage clip 21 in inclined hole, and stage clip upper end fills the steel ball 22 contacting with suspension rod; Inclined hole top arranges the thimble that can stretch in inclined hole; The upper end of suspension rod is fixed on to be adhered on bracing frame, and the lower end of suspension rod is free or fixed form.In figure, also have housing cover 23, lever bearing pin 24.
Electric block is as power lift, and wire rope is as Force transmission parts, changes and is subject to force direction by being fixed on the assembly pulley of movable pulley on vertical main framework and fixed pulley composition, power is delivered to adhere on supporting beam support body is promoted.
Take-up housing is by several reserving hole erection bolts, take-up housing is fixed on to the bottom of scaffold, when lifting power plant starts to do the used time, wire rope starts to tighten up, and movable pulley is under wire rope effect, start to move up with respect to fixed pulley, slide block, along with mobile pulley axle, moves up in take-up housing guide rail, and it is applied to lifting force upwards, because take-up housing is secured by bolts on support body, support body starts to move up.
Lifting power plant drives in integral-scaffold rising and decline process, be that lifting power plant is to the support body application of force, the push rod being now connected with power set is also simultaneously stressed, push rod applies power upwards to the left end of lever arm, under the effect of rocking pin, the other end of lever arm presses to housing cover by pin by platen, platen presses down thimble simultaneously, steel ball is depressed in the inclined hole of housing, make steel ball and circular suspension rod in contact condition not, now, rise or decline construction integral-scaffold can enter rise or decline work condition state.
In the time of lifting power plant catastrophic failure, the lifting power that lifting power plant imposes support body lost efficacy suddenly together with the external force that interlock leverage is executed simultaneously, the power that the thimble being connected with lifting power plant applies lever arm also lost efficacy, the other end of lever arm also lost efficacy to the power of platen by pin, the power that thimble acts on steel ball lost efficacy in moment simultaneously, under spring action, steel ball is along inclined hole moment bullet to circular suspension rod, and along with moment the support body kinetic energy and the potential energy that fall, make steel ball effectively lock rapidly circular suspension rod, thereby the support body that locking is fallen downwards, and circular suspension rod upper end is fixed on and adheres in supporting, be linked together with major structure of construction, thereby realize the function of integral-scaffold fall arrest.
The present invention also can carry out intellectualized reconstruction, and its intelligent synchronization technology has adopted a kind of digital intelligent hoisting control device.Control device is mainly made up of central control cabinet and isochronous controller two parts.Central control cabinet is mainly made up of contactor 25 and line breaker (thermal relay 26), drives electric block operation, and realizes lifting motor crossed to thermal overload and power phase shortage protection; Isochronous controller is made up of programmable controller (PLC) 32, speed probe (being arranged in lifting appliance) 27, lifting motor contactor drive circuit 28 and control panel (touch-screen display) 29, mainly realize the start and stop of lifting motor 30, the automatic control of scaffold integral elevating height, and show in real time adjustable height and each seat in the plane electric block running status by display.Also have that intelligence is automatic, non intelligent automatically, any switching of unit independent operation mode, to adapt to various work condition states and emergent demand simultaneously.
Intelligent automatic control: when scaffold lifting, lifting motor driven gear mechanism 31 rotates, speed probe sends tacho-pulse, acquisition counter device collects this pulse signal, counts and send to PLC, and PLC receives after umber of pulse, according to the coefficient of setting, convert umber of pulse to adjustable height, and compare with setting height, after setting height, automatically control this seat in the plane lifting motor and stop when reaching.In lifting process, PLC compares the dynamic height of each seat in the plane, calculates the adjustable height difference between each seat in the plane, and in the time that maximum difference exceeds permissible value, PLC controls the seat in the plane lifting motor running status of maximum difference, realizes synchronization lifting between each seat in the plane.
Manually control: when scaffold need enter initial lifting work condition state, when each machine need link debugging with relevant apparatus, central control cabinet can switch to " unit independent operation mode ", to realize the manually debugging directly perceived of each machine and relevant apparatus.
Non intelligent automatic control: when scaffold is in intelligent automatic control synchronization lifting operating mode, because spy sends out reason, intelligent synchronization controller cisco unity malfunction and affect scaffold lifting, and cannot get rid of in the short time time, central control cabinet can switch to " non intelligent automatic control mode ".Now, scaffold still can continue automatic lifting, and switches in real time " unit independent operation mode ", and adopts unit leveling to remedy, until scaffold lifting puts in place.
