Label in figure is: 1, suspender main body; 2, safe fence; 3, baffle plate; 4, portable cucurbit hanger; 5, safety strap link; 6, VERTICAL TUBE; 7, sleeve pipe; 8, horizontal gird; 9, cucurbit suspension centre.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.Embodiments of the present invention include but not limited to the following example.
Embodiment 1
A kind of rotor lifter as shown in Figure 1 and Figure 2, comprise suspender main body 1, suspender main body 1 upper end is workplatform, in described workplatform surrounding, one circle safe fence 2 is set, safe fence 2 bottoms arrange a circle baffle plate 3, described workplatform middle part side is fixedly installed portable cucurbit hanger 4, on portable cucurbit hanger 4, is provided with portable cucurbit, and four edges of described workplatform are also provided with safety strap link 5.
The present embodiment safe fence can prevent that it from dropping by staff's protection, and safety strap link 5 is also set, staff's safety strap can be connected on safety strap link 5, further protection staff drops, safe, and safe fence 2 lower ends arrange baffle plate 3, can effectively prevent from being placed on Work tool on workplatform and drop and cause casualties, also can avoid instrument device to drop and drag slow erection schedule; On portable cucurbit hanger 4, portable cucurbit is set, staff can lift by portable cucurbit in the time of mounting hanger protective cover, manually lifts without staff, reduces installation difficulty and intensity, and also more for convenience, safety also increases in the time that installation aligns screw.The present embodiment is by arranging portable cucurbit hanger 4, safe fence 2 and safety strap link 5; the installation difficulty that can reduce a staff and intensity, fast and easy is installed, and can well protect staff, suspender and suspender fabricated section; protectiveness is good, and practicality greatly improves.
Embodiment 2
The present embodiment has been optimized portable cucurbit hanger on the basis of embodiment 1, be specially: described portable cucurbit hanger 4 comprises the VERTICAL TUBE 6 that is fixed on workplatform middle part side, VERTICAL TUBE 6 outer ends are sheathed with sleeve pipe 7, sleeve pipe 7 top fixing horizontal crossbeams 8, on horizontal gird 8, be fixed with cucurbit suspension centre 9, cucurbit suspension centre 9 arranges described portable cucurbit.
In the present embodiment, the large axis hole of the corresponding suspender of horizontal gird 8 center, in the time installing protective cover, directly by portable cucurbit, protective cover is sling, saved the difficulty of manually lifting, reduce potential safety hazard, not only save manpower, reduced installation difficulty, and safety, efficient.
As preferably, described VERTICAL TUBE 6 and sleeve pipe 7 are reducing pipe, and the heavy caliber end of described VERTICAL TUBE 6 is welded on workplatform middle part side, and described sleeve pipe 7 is enclosed within VERTICAL TUBE 6 down with heavy caliber end.Protective cover there will be and rocks in the time of lifting, and sleeve pipe 7 is to be directly enclosed within VERTICAL TUBE 6, less stable, in the time that rocking appears in protective cover, sleeve pipe 7 can rock thereupon, rock thereby strengthen, impact lifting, and may there is potential safety hazard, to this, VERTICAL TUBE 6 and sleeve pipe 7 are arranged to reducing pipe structure by applicant, by large small-bore the cooperatively interacting of reducing pipe, can increase the stability of sleeve pipe 7, prevent that sleeve pipe 7 from rotating around VERTICAL TUBE 6 in the time of lifting, ensure carrying out smoothly of lifting, reduce potential safety hazard.
