Abstract
The invention discloses a kind of Tower crane disassembly method that can improve removal efficiency, adjust the gap of climbing support guide wheel and tower body column, hanging a section standard knot moving cart position makes the center of gravity of tower crane fall the position of articulating point on item oil-lifting jar, then unloads 8 high-strength bolts that undersetting is connected with tower body；Piston rod all stretches out, when jacking cross beam hang over tower body next stage mark time on, the connecting bolt of tower body and tower body is unloaded, piston rod is slightly risen, departs from upper and lower bearing and tower body, releases standard knot to crossbeam outer end is introduced, all cold bars living of then retracting, make to climb pawl to rest on the marking time of tower body, then stretch out whole piston rods again, again by jacking cross beam hang over tower body upper level mark time on, whole pistons of retracting, upper and lower bearing is connected with tower body, and plug bolt.The problem of this method dismounting is simple, can greatly improve the efficiency of dismounting, safer when shortening the duration, and dismantling, and it is low to solve existing efficiency when being dismantled to tower crane, and potential safety hazard is big.
Description
Technical field
The present invention relates to a kind of method, more particularly, to a kind of Tower crane disassembly method that can improve removal efficiency.
Background technology
Tower crane is a kind of crane gear also known as " derrick crane " the most frequently used on construction site, is connect with a section
Long (height) (referred to as " standard knot "), for hanging the raw material of the constructions such as working reinforcing bar, wood stupefied, concrete, steel pipe.Tower crane is
A kind of essential equipment on building site.The function of tower crane point is subject to the top lotus that arm support drawstring and counter-jib drawstring transmit
Carry, and the structure member formula by turning round pylon, turntable, bearing etc. directly passes to tower body structure by turntable.From a liter tower top
There is truncated cone pillar, lean forward or hypsokinesis truncated cone pillar, herringbone posture and diagonal brace posture.Every upper rotary tower crane is both needed to set balance weight,
Its function is supporting balance weight, to effect aspect and hoisting moment equilibrant force in opposite direction required on Construction designing
Square.In addition to balance weight, also often lifting mechanism is installed in its afterbody.Why homostasis weight is placed in counter-jib to lifting mechanism together
Tail end, first can play part counterweight effect, second increase the distance between rope reel and pinnacle of a pagoda guide wheel, with the row of sharp steel wire rope around
And avoid that disorder cable phenomenon occurs.The dosage of balance weight and the length of counter-jib inversely, and balance arm lengths and crane arm
Certain proportion relation be present again between length.Counterpoise is considerable, and light-duty tower crane typically at least wants 3 ~ 4t, and heavy is near
30t.From the point of view of the development of tower crane industry, industry and national economy, building/real estate height correlation, therefore, walked from national economy
Gesture and real estate industry's development trend see that tower crane industry development has certain scientific meaning.2010, China's economic continued
Rise since 2009 is become better situation, is had laid a good foundation for industry-by-industry development, real estate industry is returned rapidly therewith
Rise, tower crane industry also has obvious rising, is counted according to China Construction Machinery association, tower crane sales volume breaks through 40,000 within 2010.2011
Year is influenceed by Real Estate Regulation, motor-car accident, Earthquakes in Japan etc., and tower crane market scale rate of expansion has slowed down, but still is kept
More than 10% speedup.Into 21 century, Chinese Tower hanging industry entirety general layout also has a very large change.Constantly there is new enterprise
Industry enters tower crane industry.But tower crane is complicated, when being dismantled to tower crane, efficiency is low, and potential safety hazard is big.
The content of the invention
It is an object of the invention to overcome above-mentioned existing tower crane complicated, when being dismantled to tower crane, efficiency is low, and
And potential safety hazard it is big the problem of, devise a kind of Tower crane disassembly method that can improve removal efficiency, this method dismounting is simple, energy
Enough greatly improve the efficiency of dismounting, safer when shortening the duration, and dismantling, it is complicated to solve existing tower crane, right
The problem of efficiency is low when tower crane is dismantled, and potential safety hazard is big.
The purpose of the present invention is achieved through the following technical solutions：A kind of Tower crane disassembly method that can improve removal efficiency,
Comprise the following steps：
（1）The gap for adjusting climbing support guide wheel and tower body column is 3-5mm, hang a section standard knot moving cart position to about from
At the 10m of tower crane center, the center of gravity of tower crane is fallen the position of articulating point on item oil-lifting jar, then unload undersetting is connected with tower body 8
Individual high-strength bolt；
（2）Piston rod all stretches out, when jacking cross beam hang over tower body next stage mark time on, unload the connection spiral shell of tower body and tower body
Bolt, slightly rise piston rod, depart from upper and lower bearing and tower body, releasing standard knot to crossbeam outer end is introduced, then retracting all living cold
Bar, make to climb pawl and rest on the marking time of tower body, then stretch out whole piston rods again, jacking cross beam is hung over to the upper level of tower body again
On marking time, whole pistons of retracting, upper and lower bearing is set to be connected with tower body, and plug bolt；
（3）Decline process for a tower body above, above procedure is repeated when continuously dropping tower；
（4）During dismounting, it is necessary to removed by the principle of tearing attached wall open afterwards is first dropped；
（5）When tower crane is down to ground base altitude, dismounting is helped with automobile hanging bed, is comprised the following steps that：Counterweight is hung, and stays one piece
Counterweight, that is, balancing the 3rd position from afterbody number, counter-jib ,-dismounting crane arm is overall to ground-hangs last-block
Counterweight-dismounting counter-jib-tower cap removes-and upper and lower bearing removes, including remove power supply and drivers' cab-climb set, hound
Remove-finally remove 3 section standard knots.
In summary, the beneficial effects of the invention are as follows：This method dismounting is simple, can greatly improve the efficiency of dismounting, contracting
Casual labourer's phase, and safer when dismantling, solve that existing tower crane is complicated, and efficiency is low when being dismantled to tower crane, and
And potential safety hazard it is big the problem of.
