The lifting appliance has the advantages of capabilities of reducing the usage amount of lifting devices and reducing the cost, convenience in use and safety when being applied to lifting of the L-shaped flange tower barrel of a large wind generating set.
Description
Technical field
The utility model relates to the wind power technology field, particularly relates to a kind of L-type flange tower cylinder suspender.
Background technology
Present L-type flange tower cylinder suspender is to manufacture according to the pore size of flange hole in the tower drum flange and the center in hole; the corresponding cover suspender of the tower drum flange of every cover tower cylinder; often following problem can appear: 1, because the blower fan type of wind field is different for this reason; the tower cylinder is also different; and the flange of different parts also is not quite similar in the same tower cylinder, lifts at present a cover tower cylinder, and its suspender quantity reaches 14-18; quantity is so many, and suspender chooses and the work capacity such as installation when having increased transportation, lifting.Unicity and the limitation of tower cylinder suspender have seriously increased quantity and the cost of suspender; 2, in the processes such as design, production and processing error appears easily, cause the perforate of some tower cylinder suspender upper plates well not cooperate with the tower drum flange hole, can occur a lot of unnecessary troubles during mounting hanger, the incomplete cooperation in two holes has also strengthened bolt stress, has increased danger coefficient; 3, the tower drum flange of different parts is inconsistent in the tower cylinder, because the single and limitation of tower cylinder suspender, in use, and if there is a tower cylinder suspender to lose or damages, can not be with other tower cylinder suspender replacement.
This shows, the tower cylinder suspender of at present wind energy turbine set use exists obvious deficiency and defective in structure, use, demand further improvement urgently, therefore how to found a kind of quantity capable of reducing using, reduce cost, L-type flange tower cylinder suspender easy to use, safe, one of real important topic that belongs to current research and development.
The utility model content
The purpose of this utility model provides a kind of L-type flange tower cylinder suspender, makes it in use, can reduce the usage quantity of suspender, and has and reduce cost, advantage easy to use, safe, thereby overcomes the deficiencies in the prior art.
For solving the problems of the technologies described above, a kind of L-type flange tower of the utility model cylinder suspender comprises base plate, boatswain chair, sleeve and bolt, and wherein, described boatswain chair is captiveed joint with the base plate middle part; The position that is positioned at the boatswain chair both sides on the described base plate is provided with the hole; Described sleeve is provided with axially extending bore, and be inserted in the hole of base plate the bottom, and top and plate upper surface offset; Described bolt passes the through hole of described sleeve.
Further, the aperture in the hole of described base plate is not less than the maximum perforate of tower drum flange.
The hole of described base plate is slotted hole.
The path in the through hole external diameter of described sleeve and the hole of base plate is suitable, and the perforate of internal diameter and tower drum flange is suitable.
Also be provided with packing ring between described bolt and the sleeve.
Described base plate and boatswain chair are the integral type structure.
Described boatswain chair also is connected with suspender belt by suspension ring.
After adopting above design, a kind of L-type flange tower of the utility model cylinder suspender in the hoisting process of the L-type flange tower cylinder that is applied to large-scale wind field wind power generating set, has the advantage that usage quantity is few, cost is low, easy to use, safe.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Above-mentioned only is the general introduction of technical solutions of the utility model, and for can clearer understanding the utility model, the utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment.
Fig. 1 is the view of the utility model L-type flange tower cylinder suspender hoisting flange tower cylinder.
Fig. 2 is the I part structure for amplifying scheme drawing of the utility model Fig. 1.
Fig. 3 is each unit construction scheme drawing of the utility model L-type flange tower cylinder suspender.
Fig. 4 is tube-in-tube structure scheme drawing of the present utility model.
The specific embodiment
See also Fig. 1, shown in Figure 2, a kind of L-type flange tower of the utility model cylinder suspender, this suspender 1 comprises base plate 11, boatswain chair 12, sleeve 15 and the bolt 13 that matches with sleeve, the utility model also comprises suspension ring 4 and suspender belt 5.
Wherein, boatswain chair 12 is welded and fixed with the base plate middle part, and it is porose 17 that the position that is positioned at the boatswain chair both sides on the base plate 11 arranges, and sleeve 15 is provided with axially extending bore, and be inserted in the hole of base plate 11 bottom, and top and plate upper surface offset.The through hole 15 that bolt 13 passes sleeve is connected with the flange tower cylinder that will lift, and is provided with packing ring 14 between bolt 13 and sleeve 15.Boatswain chair 12 connects suspender belt 5 by suspension ring 4.In addition, boatswain chair 12 and base plate 11 also can be integral structure.
Further, the aperture of bottom plate hole is not less than the maximum perforate of tower drum flange, and the hole of base plate is set to slotted hole.
Please cooperate and consult Fig. 3, shown in Figure 4, the path of the slotted hole 17 of opening on sleeve outer diameter 152 and the base plate 11 is suitable, and sleeve 15 can radially move in slotted hole 17 just; Sleeve diameter 151 is suitable with the flange perforate of tower cylinder different parts.According to the difference of sleeve 15 internal diameters, sleeve 15 is set to different size, so that the bolt 13 of corresponding supporting specification is installed.The slotted hole 17 interior movements that sleeve 15 can be offered at base plate 11 according to the situation of hoisting flange so that sleeve 15 and flange perforate is fine to heart function, efficiently solve the matching problem of suspender and flange hole.The replaceability of sleeve is strong simultaneously, need only the sleeve 15 of replacing different size according to the size situation in tower drum flange hole, realized the application theory of " one-to-many ", as long as manufacture several corresponding sleeves 15, the suspender usage quantity significantly reduces (6 suspenders), greatly reduces cost.
During use, to mounting hanger 1 on the tower drum flange face of needs lifting, concrete sequence of erection is as follows, at first the good suspender of base plate 11 and boatswain chair 12 welding is placed on the flange face, then select suitable sleeve 15 according to the size of flange hole, adjust suspender 1 and sleeve 15 positions thereof, its sleeve diameter 151 is cooperated with the tower drum flange hole, packing ring 14, bolt 13, nut 16 are installed at last in turn, and urgent moment.A kind of L-type flange tower of the utility model cylinder suspender is mainly used in the lifting of the L-type flange tower cylinder of large-scale wind field wind power generating set.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in the protection domain of the present utility model.
