Detailed description of the invention
A kind of elevating scaffold, including support body 1, support body fills electric block 2, the lifting rope 3 that electric block drives through be fixed on after assembly pulley with assembly pulley above on the attachment bracing frame 4 that connects of building, described assembly pulley is loaded on support body, the lower section of electric block；Described assembly pulley is made up of two pulleys, the fixed fixed pulley of one of them pulley 5, and another pulley is movable pulley 6 moving up and down；Arranging the steel pipe guide rail being made up of the vertical seamless steel pipe 7 of front and back two on support body, arrange, on attachment bracing frame, the ring ring being made up of the non-linear arc wheel 8 in two groups, left and right, steel pipe guide rail is positioned at ring ring, coordinates with ring ring.
Described movable pulley is fixing with slide block 9 lower end to be connected, 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 fixing with support body to be connected；The upper end of slide block is connected with mobile stress frame 11, and mobile stress frame 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 includes the pin 15 contacted with linkage lever 13, and pin is connected with platen 16, and platen is sleeved on fixing post 17, can move up and down along fixing post；Fixing post is loaded on housing 18, and housing is fixed on support body；Housing and platen central authorities are respectively provided with the medium pore installing suspension rod 19, arrange at least two inclined holes 20 in housing, and the upper end of inclined hole communicates with the medium pore of housing, are placed with stage clip 21 in inclined hole, and stage clip upper end fills the steel ball 22 contacted with suspension rod；Inclined hole is provided above stretching into the thimble in inclined hole；The upper end of suspension rod is fixed on attachment bracing frame, and the lower end of suspension rod is free or fixed form.Figure also has housing cover 23, lever bearing pin 24.
Electric block changes Impact direction as power lift, steel wire rope as Force transmission parts, the assembly pulley consisted of the movable pulley being fixed on vertical main framework and fixed pulley, transfers force to make support body promote on attachment backbar.
Take-up housing installs bolt by several reserving holes, take-up housing is fixed on the bottom of scaffold, when lifting power plant starts to act on, steel wire rope starts to tighten up, and movable pulley is under steel wire rope effect, begin to move up relative to fixed pulley, slide block, along with mobile pulley axle, moves up in take-up housing guide rail, and it is applied lifting force upwards, owing to take-up housing is secured by bolts on support body, support body begins to move up.
During lifting power plant drives integral-scaffold to rise and declines, support body is exerted a force by i.e. lifting power plant, the push rod being now connected with power set also simultaneously stress, push rod applies power upwards to the left end of lever arm, under the effect of rocking pin, platen is pressed to housing cover by pin by the other end of lever arm, bear down on one under platen pin simultaneously, steel ball is depressed in the inclined hole of housing, steel ball is made to be in not contact condition with circular suspension rod, now, carry out rising or falling the integral-scaffold of construction to enter and rise or fall work condition state.
When lifting power plant catastrophic failure, the lifting force that support body is imposed by lifting power plant lost efficacy together with the external force being executed linkage leverage the most simultaneously, the power that lever arm is applied by the thimble being then connected with lifting power plant also lost efficacy, the power of platen was also lost efficacy by the other end of lever arm by pin, thimble acts on the power on steel ball and lost efficacy in moment simultaneously, under the action of the spring steel ball along inclined hole moment bullet to circular suspension rod, and the kinetic energy that falls along with moment support body and potential energy, steel ball is made the most effectively to lock circular suspension rod, thus the support body that locking is fallen downwards, and circle suspension rod upper end is fixed in attachment supporting, i.e. it is linked together with major structure of construction, it is achieved thereby that the function of integral-scaffold fall arrest.
The present invention also can carry out intellectualized reconstruction, and its intelligent synchronization technology have employed a kind of digital intelligent hoisting control device.Control device to be mainly made up of central control cabinet and isochronous controller two part.Central control cabinet is mainly made up of catalyst 25 and chopper (thermorelay 26), drives electric block to run, and realizes lifting motor is crossed thermal overload and power phase shortage protection；Isochronous controller is made up of programmable controller (PLC) 32, speed probe (being arranged in lifting device) 27, lifting motor contactor drive circuit 28 and control panel (touch-screen display) 29, mainly realize the start and stop of lifting motor 30, automatically controlling of scaffold integral elevating height, and show adjustable height and each seat in the plane electric block running status in real time by display.The most also there is intelligence automatic, any switching laws of unit independent operation mode automatic, non intelligent, to adapt to various work condition state and emergent demand.
Intelligent automatic control: during 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, after PLC receives umber of pulse, according to the coefficient set, umber of pulse is converted into adjustable height, and compares with setting height, after reaching setting height, automatically control this seat in the plane lifting motor stop.In lifting process, the dynamic height of each seat in the plane is compared by PLC, calculates the adjustable height difference between each seat in the plane, and when maximum difference is beyond permissible value, PLC controls the seat in the plane lifting motor running status of maximum difference, it is achieved synchronization lifting between each seat in the plane.
Non-follow control: initially lift work condition state when scaffold need to enter, when each machine need to carry out linkage debugging with relevant apparatus, central control cabinet can switch to " unit independent operation mode ", to realize the debugging the most directly perceived of each machine and relevant apparatus.
Non intelligent automatically control: when scaffold is in intelligent automatic control synchronization lifting operating mode, owing to spy sends out reason, intelligent synchronization control device cisco unity malfunction and affect scaffold lifting, and when cannot get rid of again in the short time, central control cabinet can switch to " non intelligent automatic control mode ".Now, scaffold may continue to automatic lifting, and switches in real time " unit independent operation mode ", and uses unit leveling to remedy, until scaffold lifting puts in place.
