Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only of the invention
A part of the embodiment, instead of all the embodiments.Based on the embodiment of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
As shown in figs. 1-12, a kind of nothing adds the tower barrel of wind generating set of weldment, comprising: 1 foundation ring, 2 bottoms section, 3
Middle and lower sections, upper section in 4,5 top sections, 6 changeover portions, 7 platforms, 8 climbing ladder apparatus, 9 cable units, 10 counterbalancing framves, 11 main drag-lines,
12 secondary drag-lines, 13 platform locating racks.
As shown in Fig. 1,2,3,5,6,1 lower part of foundation ring is connect with ground, and foundation ring upper flange 1-1 passes through the lower bolt of bottom section
2-2 is connect with the bottom section lower flange 2-1 of bottom section 2;Bottom section 2, middle and lower sections 3, middle upper section 4, top section 5, changeover portion 6 are bottom-up successively
It is connected by high-strength bolt, changeover portion 6 is connected by the cabin of changeover portion upper flange 6-1 and wind power generating set.Above-mentioned is tower
The connection of cylinder main body, in this case, by taking four sections of cylinders, changeover portion, basic ring structure as an example:
It is top-down as shown in Fig. 1,2,3,5,6,7, using changeover portion lower flange 6-2, top section upper flange 5-1 and this two
The upper bolt 5-3 of top section between part flange installs counterbalancing frame 10, and wherein tripod 10-1 is connect with bolt 5-3 in the section of top;It is main
The screw rod 11-1 of drag-line 11 is connect with tripod 10-1;The inner hole both ends of sleeve 11-2 are machined with left-handed and right-handed thread respectively,
Threaded upper ends are connect with screw rod 11-1, and lower thread is connect with pull rod 11-3, and the upper end drag-line 11-4 is connect with pull rod 11-3, drag-line
The lower end 11-4 passes through second pull rod 11-3, second sleeve 11-2, second screw rod 11-1 and second counterbalancing frame 10
Tripod 10-1 connection.In this way, the upper flange of tower top section and the lower flange of bottom section are connected by main drag-line 11.Each anti-
It is furnished with two pieces balancing stand 10-2 to balancing stand 10, is symmetrically arranged, horizontal plane is connect with tripod 10-1, and vertical plane is (interior
If screw thread) it is connect with mandril 10-3, mandril 10-3 is made of bolt and jacking block.Adjust the sleeve 11-2 and screw rod on main drag-line 11
The screwing length of 11-1, pull rod 11-3 tense winner's drag-line 11, will generate moment of flexure to tripod 10-1;Adjust top again at this time
Bar 10-3 makes its end hold out against tower drum flange internal diameter in the screwing length of balancing stand 10-2, right so as to offset main drag-line 11
The moment of flexure that tripod 10-1 is generated.Then, counterbalancing frame 10, main drag-line 11 and tower drum flange are in new equilibrium state, main
Bearing structure of the drag-line 11 as attachment in tower, only generates axial compressive force to tower drum flange, has substantially no effect on tower drum flange bolt
Connection effect.Counterbalancing frame 10, main drag-line 11 are preferably 8 groups of masters according to can choose different size, different number, this example
Drag-line.
As shown in Fig. 2,3,4,5,8,9, platform board 7-2, ladder cover board 7-3 are installed on landing beam 7-1, according to tower cloth
It sets needs and is equipped with ladder hole 7-2-1, cable aperture 7-2-2, drag-line hole 7-2-3 on platform board 7-2;Landing beam 7-1 can be used
Various structures pattern, this example be preferably " well " shape, landing beam 7-1 by drag-line seat 7-4, platform drag-line 12-2, rope clamp 12-1 with
Main drag-line 11 connects, so that platform 7 be made to overhang in tower vertically.The mounting rack 13-1 and landing beam 7-1 of platform locating rack 13
Connection;Telescopic rod 13-2 is screwed by the vertical plate of bolt and mounting rack 13-1;Spring assembly 13-3 is connect with telescopic rod 13-2;For
It is conveniently adjusted angle, the locating rack mounting hole 7-1-1 on landing beam 7-1 is set as a circular hole with a unification long hole.Adjust platform
Setting angle of the locating rack 13 on landing beam 7-1, the extension elongation for then adjusting telescopic rod 13-2 push up spring assembly 13-3
Tight tower inner wall, to make 7 horizontal location of platform.
As shown in Fig. 2,3,4,5,10, the cable 9-1 of cable unit 9 is installed in cable clip 9-2, the both ends cable clip 9-2
It is connect with drag-line 11-4.
As shown in Fig. 2,3,4,5,11,12, ladder 8-1 is connect by ladder seat 8-2, suspension cable 8-3 with platform 7;Screw rod
Group 8-1-3 passes through riding club 8-1-2, ladder beam 8-1-1 and connect with the side plate 8-2-2 of ladder seat 8-2, and bottom plate 8-2-1 is installed on platform
On beam 7-1;The one end suspension cable 8-3 is connect with ladder beam 8-1-1, and the other end is connect with landing beam 7-1.
The working principle of the present invention program is as follows: on the basis of conventional tower, utilizing top flange and bottom flange and flange
Connection bolt installs bearing structure of the main drag-line 11 as all tower internals, due to arranging counterbalancing frame 10, flange spiral shell
The switching performance of bolt is unaffected.Platform 7 is positioned in vertical direction by secondary drag-line 12, is realized by platform locating rack 13 flat
The horizontal direction of platform 7 positions.Cable unit 9 is installed on main drag-line 11.Climbing ladder apparatus 8 is installed on platform 7, and passes through oblique pull
Rope 8-3 realizes horizontal location.
After above-mentioned apparatus, it can all cancel the welded attachment on cylinder, give full play to the bearing capacity of tower, thus
Reduce tower weight and cost;And each layer platform, ladder, cable are easily installed and adjust position.
