Description
Technical field
The present invention relates to vehicle for construction field, at length say it is a kind of steel column Lift-on/Lift-off System.
Background technology
As everyone knows, detached column lifting conventional in structural steelwork construction is at present, at capital, hanger is set separately, utilize steel bar and automatically-unhooked system to lift, finally hanger is excised, then the touch-up paint of polishing in hanger position, before lifting, on steel column, weld hanger like this, waste of manpower, material resources, financial resources, when hanger excises after rigging out, aspect safety and efficiency, just there will be following several problem: first, during excision, belong to aloft work, no matter be, before rack is installed or after installing, excise, all can not provide a job platform for workmen, therefore a job platform must be artificially set excises, no matter this platform is movable Scaffold or hanging ladder, or even steel cat ladder, all need to spend more manpower or elevator machinery moves man-hour, reduced greatly work efficiency.The second, the cutting of hanger, the work difficulty of polishing are all larger, are difficult to reach requirement in perception.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of steel column Lift-on/Lift-off System, realized lifting device at ground Assembly &Disassembly, operating efficiency is high, and security risk is low, can reuse, steel member itself is not done to any change again, thereby safety, practicality, economy are all fine.
The technical solution adopted for the present invention to solve the technical problems is: a kind of steel column Lift-on/Lift-off System, be provided with cuff, it is characterized in that, cuff is " mouth " font structure, its three angles are hinged through bolt, the upside at another angle is fitted with steel bar, on relative two frames of cuff, be processed with hanger, two hangers are connected with two hangers of fringed iris herb below through steel rope, two hangers of fringed iris herb top hang on hoisting machinery lift hook through steel rope, a fixed pulley is also installed on hoisting machinery lift hook, on fixed pulley, be wound with hauling rope, one end of hauling rope is fixed on steel bar.
The present invention also can be achieved by the following measures: the lower end of steel bar is connected with safety rope.On cuff, be fixed with a wire rope handling ring, hauling rope passes in wire rope handling ring.
The invention has the beneficial effects as follows, realized lifting device at ground Assembly &Disassembly, operating efficiency is high, and security risk is low, can reuse, and steel member itself is not done to any change again, thereby safety, practicality, economy are all fine.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention, is also the schematic diagram of a kind of embodiment.
Fig. 2 is the schematic diagram of cuff of the present invention.
Fig. 3 is the structural representation of fringed iris herb of the present invention.
1. steel ropes in figure; 2. fringed iris herb; 3. cuff; 4. abacus; 5. steel column; 6. steel bar; 7. wire rope handling ring; 8. fixed pulley; 9. hauling rope; 10. hoisting machinery lift hook, 11. safety ropes.
The specific embodiment
In Fig. 1, the present invention is provided with cuff 3, and cuff 3 is " mouth " font structure, and its three angles are hinged through bolt, and the upside at another angle is fitted with steel bar 6, and the lower end of steel bar 6 is connected with safety rope 11.On relative two frames of cuff 3, be processed with hanger, two hangers are connected with two hangers of fringed iris herb 2 belows through steel rope 1, two hangers of fringed iris herb 2 tops hang on hoisting machinery lift hook 10 through steel rope, a fixed pulley 8 is also installed on hoisting machinery lift hook 10, on fixed pulley 8, be wound with hauling rope 9, one end of hauling rope 9 is fixed on steel bar 6, is fixed with a wire rope handling ring 7 on cuff 3, and hauling rope 9 passes in wire rope handling ring 7.
Cuff 3 of the present invention is four connecting ring type structures, and cuff 3 is " mouth " font when closed, in order to mesh the abacus 4 of steel column." mouth " font cuff 3 interior leading dimensionss are less than abacus 4 outer profile sizes, thereby guarantee that cuff 3 can not come off from steel column abacus 4 in installation process.Three high strength bolts that intersection location is set to not tighten in length and breadth of " mouth " font connect, the 4th the steel bar 6 that connection location is arranged to penetrate up and down, cuff 3 closures when steel bar 6 penetrates, while extracting, cuff 3 can launch, thereby makes the interior leading dimensions of cuff 3 be greater than the object that abacus 4 outer profile sizes depart to reach cuff system and steel column 5.Cuff 3 is comprised of " Π " shape and "T"-shaped steel plate respectively, forms three block plate overlaying states in junction.For guaranteeing the smooth folding of cuff 3, between three ply board is folded, gap is set to 2mm, and more than high strength bolt is lengthened to 15mm than common calculated length, makes nut have enough move places, has guaranteed the smooth folding of cuff 3.
Steel bar 6 is designed to round table-like, after insertion cuff 3, can by cuff 3, not clamped and be difficult to extract.Steel bar 6 lower ends are processed with eyelet hole in order to penetrate safety rope 11, and safety rope 11 is extended down to ground and is dragged tightly by special messenger, and safety rope 11 is not extracted steel bar 6 out can not deviate from cuff 3; Steel bar 6 upper ends and hauling rope 9 one end are tied, on hoisting machinery lift hook 10, hang a fixed pulley 8, the hauling rope 9 of steel bar 6 upper ends extends to ground by fixed pulley 8, after a steel column rigging out, will pull hauling rope 9 downwards pulls out steel bar 6, cuff 3 is opened and then cuff 3 is taken off, thereby reached personnel, makes the cuff 3 in high-altitude and the object of steel column disengaging in terrestrial operation.
Cuff 3 upper ends are connected with a fringed iris herb 2 by steel rope, make steel column 5 automatically in vertical state, have improved steel column 5 installation effectiveness, also easier when cuff 3 departs from steel column 5.
The invention enables lifting device installation and steel column lifting synchronously to carry out, realized lifting device at ground Assembly &Disassembly, operating efficiency is high, security risk is low, can reuse, steel member itself not done to any change again, thereby safety, practicality, economy are all fine.
In engineering, need according to the weight of lifting weight, corresponding wirerope diameter and high strength bolt to be selected, suppose 3 tons of steel column gross weights, steel column state, for lying low, is stood up after cuff installs.Each cuff has four points of connection, supposes that steel column stands up to only have two cover high strength bolts stressed in process.Consider extreme case, only have a set of bolt strained.Connecting joint are that three ply board is folded, and screw rod is subject to double shear.
