Disassembly process it is as follows：
The roofing device for hoisting given an account of and continued is installed, roofing device for hoisting is installed near tower crane 6, and arm 14 is higher than the tower of tower crane 6
61 position of cap；
Fig. 3-Fig. 6 is referred to, tower crane 6 contacts the position intersected with roof and is provided with a lower sheave 7, and lower sheave 7 passes through fastening
Bolt 4 is fixed on clamping plate 8 on the cross bar 651 for the standard knot 65 that tower crane 6 is contacted with roof, the hoist rope of itself of tower crane 6
66 one end is fixed on the 6th fixed pulley 26 on the counter-jib 63 of tower crane 6, and the other end bypasses be installed on tower cap 61 successively
The end of crane arm 62 is connected to after 7th fixed pulley 27, lower sheave 7.
Suspension hook 19 on roofing device for hoisting 1 tangles crane arm 62 by steel wire rope, passes through the first steel on roofing device for hoisting 1
Cord 51 controls the lifting of arm 14, by rotating mechanism 12, rotates Circumflex branch frame 13, so that crane arm 63 steadily be dismantled simultaneously
It is placed on roof；The steel wire rope for being bundled with counter-jib 63 is tangled by suspension hook 19, smoothly counter-jib 63 is dismantled and placed
On roof；Tangled by suspension hook 19 and be bundled with counterweight 64, tower cap 61, rotating assembly 67, jacking stock assembly 68 and standard knot 65,
Counterweight 64, tower cap 61, rotating assembly 67, jacking stock assembly 68 and standard knot 65 are dismantled respectively；Individually set again on roof
One gin-pole truck, by setting gin-pole truck to dismantle roofing device for hoisting on roof；Utilizing indoor electric after gin-pole truck mutual disassembly
Ladder is transported to ground.
In the present embodiment, it is minimum from roofing first with climbing system in tower crane 6 itself by tower crane 6 and being down to before tower crane 6 is dismantled
Position, in frame position of climbing that tower crane is fixed, mobile roof hangs 1 revolution, and 1 arm 14 is hung using roofing and hangs 4 pieces and matches somebody with somebody
Weight, stays one piece to match somebody with somebody recast balanced action, and device for carrying a tripot bar is installed two " people " font barres and hung under 62 leading portion second of lifting section（Figure is not
Show）, toppled with what 5T chain blocks control barre was hung to reach the effect of control 19 central point of suspension hook.Utilize 6 raising steel of tower crane
Section 7 crane arm 62 is sling stress by cord 66 as traction power, is then destroyed crane arm 62 and is connected axis pin, slightly by 5T hands
Draw cucurbit to unclamp distance element, Section 7 crane arm and Section 6 crane arm is had distance, then start main hoisting mechanism（It is not shown）,
Crane arm 62 is hung to ground, roofing device for hoisting 1 is utilized by the 50 of tower crane 6 after removing Section 5 crane arm successively using the method
15 degree of angles are lifted by crane in 62 front end of rice crane arm, bend front tension bar, roofing device for hoisting is disposable by 40 meters of crane arms 62 with suspension hook 19
It is hung to roofing.
In the present embodiment, the step of dismounting counter-jib 63 are：
A. remaining one piece of counterweight block is hung down with roofing device for hoisting 1；
B. the installation lifting lug on counter-jib 63 is passed through（It is not shown）, counter-jib 63 is sling with roofing device for hoisting 1, allows counter-jib 63
Pull rod is in unstressed state, dismantles the connecting pin among 63 pull rod of counter-jib；
C. counter-jib 63 is sling, is put into ground and is lined with the bearing of sleeper.
In the present embodiment, the step of dismounting counter-jib 63 are：
A. rope is fixed on above the lifting lug at tower crown end, slowly tenses rope；
B. dismounting and connecting pin；
C. tower cap is sling, ground is put it to and is lined with the bearing of sleeper.
Whether with adjacent component between have cable be connected, safety member is housed on tower cap if checking, protection is paid attention in hoisting process,
It is to pay attention to being pressed onto in safety member hoisting process paying attention to allow tower cap amplitude of fluctuation during movement being put into ground
It is excessive, in order to avoid collide with other components.
In the present embodiment, the mode for dismantling rotating assembly is：Rotating assembly includes upper bracket, undersetting, pivoting support
And drivers' cab；
A. 8 M30 × 360-10.9 grade high-strength Bolt dismantlings undersetting being connected with standard knot get off；
B. rope is fixed on above upper bracket, slowly tenses rope, lower 4 connecting pins between undersetting and climbing support of dismounting
Axis；
C. rotating assembly 67 is sling, is placed into ground and is lined with the bearing of sleeper.
Therefore, dismounting rotating assembly 67 is it is noted that 6 component of tower crane is destroyed, equipped with perhaps on rotating assembly 67 in the present embodiment
More electric components, it should be noted that protection, it is noted that protecting the easily damaged part such as drivers' cab in disassembly process.
Therefore, the mode of dismounting jacking stock assembly is in the present embodiment：
Rope is fixed on four chord members on jacking stock top, it is hung oneself from the standard knot of tower crane with roofing device for hoisting 1
Go out, be placed into ground and be lined with the bearing of sleeper, when jacking stock hangs out tower body completely, it is impossible to which oblique pull jacks stock.
The mode of the remaining standard knot of dismounting is：Steel wire rope will be fixed on standard knot, remaining standard knot is removed with suspension hook 19,
Dismantle base section and the grade component of lower sheave 7.
Fig. 7-Fig. 8, is finally the dismounting to roofing device for hoisting 1, the method for dismounting of roofing device for hoisting 1 is except roofing is lifted
The arm 14 put is lowered into roof, outside mutual disassembly, when used roofing device for hoisting 1 is larger, by roofing device for hoisting
Near the roofing device for hoisting of a small size is installed again, the roofing that the arm hung with small size roofing removes large volume lifts
[K1]。
When artificial realizing self disassembling roofing device for hoisting 1, it usually needs a gin-pole truck 90 is dismantled as auxiliary body, is taken off
Bar hangs 90 and is typically mounted near roofing device for hoisting 1, its specific mounting means is as described in Figure, by four of cross girder steel 91
Endpoint and crossover sites are fixed by the pre-embedded bolt 92 on roof, and each 92 lower end of pre-embedded bolt is both provided with bearing plate
93, fix gin-pole truck base 90 on four sides of cross girder steel 91, by the fixed pulley connecting steel wire ropes on gin-pole truck and
Amplitude variation trolley dismantles roofing device for hoisting 1, after dismantling ten thousand roofing device for hoisting 1,90 mutual disassembly of gin-pole truck, utilizes indoor elevator
It is transported to ground.
Advantage of the invention is that：
1）The basic girder steel that the present invention hangs roofing on base is fixed by penetrating the fastening bolt of the beam slab on roof, and is provided with
Parallel pressing plate grips basic girder steel with beam slab, hangs on stability when carrying gravity to reduce roofing, is allowed to transport
It is dynamic more steady；
2）And utilize this roofing device for hoisting, the position that contact of the tower crane with roof intersects installation one lower sheave, pass through by
Hoist rope installed in tower crane itself passes through the lower sheave and crane arm, and crane arm is kept balancing, and in roofing
Under the traction of the suspension hook hung on, steadily, crane arm is rapidly dismantled, this mode is especially suitable for the dismounting of overlength crane arm；
3）After crane arm dismounting, the roofing device for hoisting is recycled to cover the counter-jib of tower crane, counterweight, tower cap, rotating assembly, jacking
Frame assembly and standard knot are dismantled successively, and disassembly process is simple, and are dismantled steady.
Disclosed above is only several specific embodiments of the present invention, but the present invention is not limited to this, any ability
What the technical staff in domain can think change should all fall into protection scope of the present invention.
