Abstract
Provided is a guide pin used for flange bolt holes for hoisting butt joint of wind turbine tower drums. The guide pin comprises a pin rod and a pin cap, wherein one end of the pin rod is in a conical shape, the other end of the pin rod is welded to the pin cap, the diameter of the pin rod is the same as that of a flange bolt of each wind turbine tower drum, and the pin cap is the same as a bolted cap of the flange bolt in size. By the adoption of the guide pin used for the flange bolt holes for the hoisting butt joint of the wind turbine tower drums, in the hoisting butt joint process of the wind turbine tower drums, the flange bolt holes of an upper section of tower drum and a lower section of tower drum are aligned fast and accurately, and the hoisting speed is improved.
Description
Technical field
The utility model relates to a kind of leading along pin for wind turbine tower cylinder lifting abutted flange bolt hole.
Background technique
Wind-driven generator is mainly by tower body, cabin, wind wheel forms, tower body is that some sections tower cylinders adopt flange bolt to be formed by connecting, in traditional cylinder tower abutting joint technique, often adopt epimere tower cylinder is slowly transferred to contacting with hypomere tower cylinder face, the flange bolt that interts between the tower drum flange bolt hole again connects, because tower cylinder weight is large, build is large, lifting is high-lift operation in addition, wind speed is larger, rocking due to the tower cylinder in decentralization process, be difficult to the flange bolt hole between two head tower cylinders is alignd, often to lift by crane repeatedly, adjust and repeatedly just can complete the alignment of flange bolt hole, waste time and energy, inefficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of leading along pin for wind turbine tower cylinder lifting abutted flange bolt hole, the docking of can fast and accurately the flange bolt hole between two head tower cylinders being alignd with settling at one go, make technique change the tool type fast operating into by loaded down with trivial details repeatable operation process, improve installation efficiency.
The utility model is by achieving the above object by the following technical solutions: a kind of leading along pin for wind turbine tower cylinder lifting abutted flange bolt hole, comprise pin rod and pin cap, pin rod one end is coniform, the other end and the welding of pin cap, the pin rod diameter is identical with the flange bolt diameter of wind turbine tower cylinder, and pin cap size is identical with the nuts of flange bolt.
Described pin rod length is 400～500mm.
Described pin rod adopts the high tensile metal rod to make through polishing.
Outstanding advantages of the present utility model is:
In the lifting docking operation of wind turbine tower cylinder, adopt described flange bolt hole of leading along the disposable alignment of pin guiding epimere tower cylinder energy in decentralization process hypomere tower cylinder with putting in place, avoid two sections tower cylinder being connected the adjustment repeatedly in the process of hole, improved the lifting speed of tower of wind generating set cylinder.
The accompanying drawing explanation
Fig. 1 is the elevational schematic view along pin of leading for wind turbine tower cylinder lifting abutted flange bolt hole described in the utility model.
Fig. 2 is leading along the pin floor map for wind turbine tower cylinder lifting abutted flange bolt hole described in the utility model.
Fig. 3 is the use view along pin of leading for wind turbine tower cylinder lifting abutted flange bolt hole described in the utility model.
Embodiment
Below by drawings and Examples, the technical solution of the utility model is described further.
As shown in Figure 1 to Figure 3, the suitable pin of leading for wind turbine tower cylinder lifting abutted flange bolt hole described in the utility model, comprise pin rod 1 and pin cap 2.
Described pin rod adopts the high tensile metal rod to make through polishing, and the pin rod diameter is identical with the flange bolt screw rod, and length is 400～500mm, and pin rod one end is coniform, and the other end is connected with the pin cap.
Described pin cap 2 is for adopting nuts to make, and the nuts of nuts and flange bolt is identical.
Described pin rod 1 is connected through spot welding with pin cap 2.
The using method along pin of leading for wind turbine tower cylinder lifting abutted flange bolt hole described in the utility model, comprise the steps:
A) fix two for manually operated nylon drag-line in epimere tower cylinder bottom, adopt loop wheel machine equipment that 5, epimere tower cylinder is winched to the height apart from 900mm～1000mm directly over hypomere tower cylinder 6 flange connection surfaces;
B) loop wheel machine is transferred epimere tower cylinder 5 slowly, drops down onto the height apart from hypomere tower cylinder 6 flange connection surface 500mm～600mm.The personnel that the nylon drag-line is responsible for controlling in ground strain drag-line, avoid rocking of epimere tower cylinder.
C) the interior operator of hypomere tower cylinder 6 lead along pin 1 and insert from from top to down in the flange bolt hole of epimere tower cylinder 5 two, lead the position that is laid in relative 180 ° of angles of epimere tower cylinder 5 flanges along pin 1 for two;
D) loop wheel machine coordinate artificial drag-line by epimere tower cylinder 5 slowly under, leading while along pin 1 lower end, being about to touch hypomere tower cylinder 6 flanged surface, loop wheel machine stops issuing;
E) after being positioned at operator on 6 faces of hypomere tower epimere tower cylinder 5 being adjusted to the docking angle, then continue slowly to transfer, in decentralization process, two are led along pin 1 and insert in the flange bolt holes 4 of hypomere tower cylinder 6 correspondences;
F) two lead along pin 1 insert the flange bolt hole 4 of hypomere tower cylinder 6 correspondences interior after, commander's loop wheel machine continue to transfer epimere tower cylinder 5 to hypomere tower cylinder 6 interfaces, loop wheel machine does not break off relations, and keeps status under loading;
G) extract and lead along pin 1, at two sections tower drum flange junction surface, all bolts are installed, and, after tightening by designing requirement, loop wheel machine is removed load-bearing, installment work completes.
Claims (2)
