Embodiment
Below by taking the aerial vestibule of Nanjing ancient cooking vessel positive purchase of property No.2011G38 plot project as an example, the project needed in construction by
Vestibule truss is promoted to the height apart from ground level 71m.The method of this example is that vestibule truss is divided into three sections, including two ends
Truss and a middle truss；Two end truss directly both sides construction ceiling assembly in place, and taken at the top of two end truss
If promoting platform 1 as truss support in being promoted；Middle truss is incited somebody to action after installation on ground is integral, then through the device of four this example
Middle truss Integral synchronous promotion is docked with both ends truss in place.The weight of this example is middle truss.The length of middle truss is 30m left
It is right.4 tubular type hydraulic cylinders are configured, it is corresponding with four suspension centres on middle truss.
Before lifting, first four cable wires 2 are passed through from the interstitial hole of 4 tubular type hydraulic cylinders respectively, the specific threading method of cable wire 2
Be one end of cable wire 2 is sequentially passed through from top to bottom upper locking device 4, the interstitial hole of tubular type hydraulic cylinder 3 and lower locking device 5 with
Four suspension centres connection on middle truss.2 other end of cable wire rides on leading truck 6.Four cable wires 2 are tensed and then are passed through telescopic rod
The upper locking device 4 at 14 tops locks cable wire；Since the locking plate 18 in upper locking device 4 is equipped with spine with 2 contact site of cable wire
Tooth will not be locked tight device so cable wire 2 can slide on ratchet when pulling up cable wire 2 at the top of upper locking device 4
4 is locked.When weight has been hung in 2 lower end of cable wire, cable wire 2 is bitten cable wire 2 by ratchet and cannot be slided on ratchet to lower stress, cable wire 2
It is dynamic, it can only be moved down simultaneously with ratchet.Inverted cone is surrounded by the locking plate 18 of circumference uniform distribution moving down due to one group
When, limited, made by the locking plate 18 of circumference uniform distribution to contract by horn mouth 17 on tubular type cylinder body 8, tightly embrace cable wire 2,
And the strength of the weight more holding of relocking piece 18 cable wire 2 is bigger.After upper locking device 4 locks cable wire 2, start hydraulic pump to pipe
8 annular piston of formula cylinder body, 13 bottom is filled with hydraulic oil, and under the promotion of hydraulic oil, telescopic rod 14 extend out to top dead-centre upwards,
Weight 7 is promoted a stroke height of tubular type hydraulic cylinder 3 with running wire 2 by telescopic rod 14.It is hydraulic by being mounted on tubular type at this time
3 bottom of cylinder or the lower locking device 5 being mounted on promotion platform 1 lock cable wire 2；The locking process can be by locking cylinder body
20 downlink of ring slider in 16 drives the locking plate 18 in lower locking device 5 to complete to lock the movement of cable wire 2 to contract.Instantly
After locking device 5 locks cable wire 2, the hydraulic oil of 8 annular piston of tubular type cylinder body, 13 bottom is laid down, telescopic rod 14 is being self-possessed
8 bottom dead centre of tubular type cylinder body is contracted under effect completely；The monodirectional locking function of ratchet, when the telescopic rod 14 of upper locking device 4 exists
Under Gravitative Loads when retracted downward, 18 automatic unlocking of locking plate of upper locking device 4 allows the telescopic rod 14 of upper locking device 4 to exist
Retracted downward under Gravitative Loads, when contraction, not will drive 2 downlink of cable wire.In 14 contraction process of telescopic rod, weight be it is static not
Dynamic.When telescopic rod 14 is contracted to tubular type 8 bottom dead centre of cylinder body, upper locking device 4 again locks cable wire 2；Then it opens again
Hydrodynamic press pump is filled with hydraulic oil to 8 annular piston of tubular type cylinder body, 13 bottom, carries out the promotion of the 2nd stroke, repeats the above mistake
Weight 7 is promoted to predetermined altitude by Cheng Zhizhi.
The weight of this example is the middle truss of overall package, can be with two ends purlin after truss is promoted to predetermined altitude in the middle
Frame docking.
After the device and method for improving of this example, many high-altitude truss can be promoted to again specified after the completion of installation on ground
Height is installed, and is greatly reduced high altitude operation work amount, is conducive to construction safety.It, being capable of operation due in ground construction
Face parallel construction also facilitates the cooperation of each profession, smaller to the construction infection of other professions, hydraulic pressure lift operation absolute time compared with
It is short, duration cost can be reduced.Engineering temporary facility can be made to minimize, be conducive to construction cost control.Without setting up interim branch
Support and rental big machinery and moulding bed, can reduce construction cost.
