Abstract
The utility model discloses an internal brace stay used for preventing deformation of a flange on a wind power generation tower during transportation. The internal brace stay includes a No.1 tube which includes a long tube and a short tube, wherein the long tube and the short tube are connected through a stud, screw threads in opposite directions are formed at two ends of the stud, a left-hand nut and a right-hand nut are respectively mounted at the two ends of the stud, a through hole is formed in the middle of the stud, and a crow bar is matched with the through hole; the other ends of the long tube and the short tube are respectively fixed in the flange through channel steel; and the internal brace stay further includes a No.2 tube which has the same structure as the No.1 tube, and the No.1 tube and the No.2 tube are fixed in the flange in a cross manner. The internal brace stay used for preventing deformation of the flange on the wind power generation tower has the advantages of simple structure, convenience for manufacture, installation and adjustment, better deformation-prevention effect, effective protection to the flange, repeated uses, and cost economization.
Description
Technical field
The utility model relates to a kind of large-scale wind generating pylon and prevents to transport the equipment of distortion, a kind of specifically wind power generation stepped flange transportation distortion inner support that prevents.
Background technique
Wind power generating set tower tube is to be assembled with high-strength bolt by the end face flange by several sections shell rings to form, and the tower tube mainly adopts single-unit or more piece, uses the automobile transportation.Plurality of advantages such as that automobile transportation has is quick and easy, mobility strong, but the automobile transportation also is subjected to the restriction of road conditions, the wind field position may be in the relatively poor remote districts of condition of road surface, the tower tube is 2～5 meters of diameters, 7～30 meters of length, weight is that tens of tons tubulose is simplified, and the long-distance and transportation process of jolting causes shell ring end face flange to lose circle most probably and can't lift, and gently then wants manufacturing firm to employ material resources, manpower, financial resources and handles; Heavy then will cause whole section shell ring to be scrapped and construction delay, cause bigger loss.How to prevent effectively that the shell ring flange distortion is an important link in the pylon transit link in the transportation process, so general manufacturing firm can add that cross or rice word flange support to prevent flange distortion in shell ring two end flange, as shown in Figure 1, the two ends of supporting are fixed by bolts on the flange, and the tapped hole of support and flange tapped hole are adaptive.But this form flange is supported on and has following problem in the actual fabrication installation process: 1, make inconvenience, need to make adaptive support according to the flange bolt hole, and be not easy to install; 2, this support be shell ring when lying low, lose under the circle state to make and form, so the anti-deforming poor effect only can guarantee further distortion of flange according to the flange bolt hole; 3, support adopts bolt to be connected with flange hole, and transporting jolts can cause screw place and bolt to form friction, extruding, thereby may form destruction to flange hole and flanged surface.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of wind power generation stepped flange distortion inner support that prevents is provided, and it can prevent better that wind power generation stepped flange is out of shape in transportation process.
Technological scheme: in order to solve the problems of the technologies described above, the utility model has adopted following technological scheme:
A kind of wind power generation stepped flange transportation distortion inner support that prevents, it comprises pipe No. one, No. one pipe comprises long tube and short tube, long tube is connected by stud bolt with short tube, the two ends of stud bolt are provided with the opposite screw thread of direction, left-handed nut and right-handed nut are installed in the two ends of stud bolt respectively, and the middle part of bolt hook bolt is provided with through hole, and crowbar and through hole are adaptive; The other end of long tube and short tube is fixed in the flange by channel-section steel respectively; It comprises also and No. two identical pipes of tubular construction that a described pipe and No. two pipes are cross-shaped and are fixed in the flange.
Wherein, described channel-section steel and flange bracket are provided with bumper, and described bumper is a soft cloth.
Wherein, described long tube and short tube are square tube.
Beneficial effect: of the present utility modelly prevent that wind power generation stepped flange transportation distortion is simple in structure, easy to make with inner support, be convenient to install; Be convenient to regulate, the anti-deforming effect is better; Effectively protect flange, and can repeat to recycle, saved cost.

Embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
Shown in Fig. 1,2,3,4 and 5, a kind of wind power generation stepped flange transportation distortion inner support that prevents of the present utility model, it comprises an identical pipe of structure, No. two pipes, a described pipe and No. two pipes are cross-shaped and are fixed in the flange.No. one pipe comprises long tube 1 and short tube 2, long tube 1 is connected by stud bolt 3 with short tube 2, and the two ends of stud bolt 3 are provided with the opposite screw thread of direction, and left-handed nut 4 and right-handed nut 5 are installed in the two ends of stud bolt 3 respectively, the middle part of bolt hook bolt 3 is provided with through hole, and crowbar 6 is adaptive with through hole; The other end of long tube 1 and short tube 2 is fixed in the flange by channel-section steel 7 respectively.Described channel-section steel 7 is adaptive with the thickness of flange; be stuck in the upper and lower surface of flange; in order to prevent channel-section steel 7 and flange contact facings wearing and tearing; thereby damage flange; influence quality of product; be provided with bumper 8 between channel-section steel 7 and flange, described bumper 8 is a soft cloth, can effectively protect channel-section steel 7 and flange contact facings.
The utility model changes existing flange supporting form into inner bearing type, after installing, use crowbar 6 to prize stud bolt 3, thereby long tube 1, short tube 2 are opened towards both sides, adjust whole support length, come verification whether to put in place by measuring multiple spot flange outside dimension, regulate flange circularity, to reach the anti-deforming purpose.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
