Abstract
The utility model discloses a kind of movable arm type internally climbing tower crane falls boom device, on internally climbing tower crane, turntable is fixed on sleeve, and pumping rod is installed with sleeve, and the inner connection chain block of pumping rod, the chain block other end are connected on the otic placode above turntable；There is bolted pulley bracket pumping rod outer end, in pulley bracket is provided with pulley.This utility model is by arranging boom device at tower crane revolution, solve the lifting blind area that large-scale movable arm type internally climbing tower crane itself is present in the past, the independent construction difficult problem for lifting cannot be realized to girder steel and interior adnexa of climbing are climbed in itself, make large-scale movable arm type internally climbing tower crane independent to itself it is heavier in climb steelwork component and install, be sent to position, a large amount of human and material resources resources are saved, the accident rate for installing vertical tower is reduced.Assembly crewman is made safely, conveniently to complete in movable arm type internally climbing tower crane, to climb the installation of part.It is particularly suited for ultra-large type swing arm internal-climbing tower crane in the interior installation climbed and part is climbed under operating mode.
Description
Technical field
This utility model belongs to climbs part mounting technique in movable arm type internal-climbing tower crane, and in particular to a kind of movable arm type
Internally climbing tower crane auxiliary hoisting device.
Background technology
Movable arm type internally climbing tower crane needs girder steel is climbed in itself when climbing and interior adnexa of climbing transports lifting to more high-storey,
Movable arm type internally climbing tower crane realizes luffing by crane arm pitching, 85 degree of maximum elevation, and the suspension hook that there is 4-8 rice around tower body is blind
Area, it is impossible to realize independent lifting.Girder steel is climbed in itself and interior adnexa of climbing just is installed in this region, and interior part requirement of climbing is lifted
Precision is higher.How individual secure, efficiently climb part in lifting and become construction Difficulties.All it was to need periphery other tower cranes in the past
To help the lifting and transhipment of part are climbed in realizing, or main rope is furthered to come using steel wire rope, pulley and a large amount of jacks
Handling is realized, this kind of mode is time-consuming, laborious, dangerous, and waste of resource, delay project construction duration.
The content of the invention
The purpose of this utility model is to provide a kind of movable arm type internally climbing tower crane and installs boom device, is climbed with improving in movable arm type
Climb part to have bad luck, install in derrick crane, improve efficiency of climbing.
The technical solution adopted in the utility model is:Movable arm type internally climbing tower crane falls boom device on turntable on internally climbing tower crane
Face is fixed with sleeve, and pumping rod is installed with sleeve, and the inner connection chain block of pumping rod, the chain block other end are connected to and turn
On otic placode above platform；There is bolted pulley bracket pumping rod outer end, in pulley bracket is provided with pulley.
Sleeve is fixed on the forward position above turntable, and sleeve outer end is connected to before upper turntable by sleeve support
On plate.Upper turntable front panel bottom is provided with people from station platform, people's platform outer end of standing is connected under upper turntable by platform support
Portion.
During work, install, operator are located in people from station platform, the bolt on the pulley bracket of pumping rod outer end is torn open
Remove, pulley bracket is removed；Another operator are located in tower body and topmost one save at standard knot platform, with two φ 16-
1m hoist cables one end is fixed on the standard section main limb of turntable lower end, and one end is fixed on suspension hook, is entered with 2 tons -3 meters of chain block
Row traction, suspension hook is furthered, and when main rope reaches the indentation, there of pulley bracket, main rope is pushed, pulley is installed
To on pulley bracket, bolt is fixed；By the chain length for adjusting chain block, can be by suspension hook apart from tower crane centrage
Quickly adjust in the range of 1.8 meters～3 meters, to climb component in completing（Climb band, interior climb frame, support steel beam）Have bad luck；All parts
After the completion of having bad luck, suspension hook is risen to into turntable bottom, remove pulley bracket, drawn by 2 tons -3 meters of chain blocks, by king wire
Rope is taken out from boom device, discharges chain block, until chain does not stress, removes chain block and hoist cable.Decline suspension hook, lead to
Luffing, revolution are crossed, after adjusting tower body perpendicularity, you can adnexa is climbed and interior girder steel of climbing is lifted, transported and installed by interior.
This utility model solves conventional large-scale movable arm type internally climbing tower crane certainly by arranging boom device at tower crane revolution
The lifting blind area that body is present, cannot realize the independent construction difficult problem for lifting to girder steel and interior adnexa of climbing are climbed in itself, make large-scale dynamic
Arm-type internally climbing tower crane it is independent to itself it is heavier in climb steelwork component and install, be sent to position, save a large amount of human and material resources and provide
Source, reduces the accident rate for installing vertical tower.Assembly crewman is made safely, conveniently to complete to climb part in movable arm type internally climbing tower crane
Installation.It is particularly suited for ultra-large type swing arm internal-climbing tower crane in the interior installation climbed and part is climbed under operating mode.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 installs and uses view for of the present utility model.
Specific embodiment
Boom device turntable 10 on internally climbing tower crane is fixed on sleeve 4 to movable arm type internally climbing tower crane, is installed with and takes out in sleeve 4
Pull bar 3,3 inner connection chain block 2 of pumping rod, 2 other end of chain block are connected on the otic placode 1 above turntable 10；Take out
There is bolted pulley bracket 53 outer end of pull bar, in pulley bracket 5 is provided with pulley 6.Described sleeve 4 is fixed on and turns
Forward position above platform 10,4 outer end of sleeve are connected on the front panel of turntable by sleeve support 7.Before upper turntable
Plate bottom is provided with people's platform 8 of standing, and 8 outer end of people's platform of standing is connected to turntable bottom by platform support 9.This utility model makes
In cyclopentadienyl STL1000C tower cranes forever, complete 10 times altogether and climb, at first the traditional working method of three employings, using steel wire rope,
Master is hung steel wire rope and furthers method to climb component handling in realizing by pulley and jack, and averagely time-consuming 12 hours/time need peace to tear people open
8 people of member；7 handlings are completed using new boom device using this, averagely time-consuming 4 hours/time need peace to tear 4 people of personnel open.This dress
Put in conveniently, safely, efficiently solving and climb component（Support steel beam, interior climb frame, climb band）Handling problem, range of application compared with
Extensively.
