Abstract
The utility model discloses a compound flange comprising a rigid flange and a reverse balance flange. The rigid flange comprises an upper steel pipe, ordinary stiffened plates and an ordinary flange plate. The ordinary flange plate is fixed at the lower end of the upper steel pipe, the ordinary stiffened plates are fixed between the outer wall of the upper steel pipe and the upper surface of the ordinary flange plate, and the ordinary flange plate is provided with first flange holes. The reverse balance flange comprises a lower steel pipe, reverse stiffened plates and a reverse flange plate. The reverse flange plates are fixed at the upper end of the lower steel pipe, the reverse stiffened plates are fixed between the upper face of the reverse flange plate and the outer wall of the lower steel pipe, and the reverse flange plate is provided with second flange holes. Bolts are mounted in the first flange holes and the second flange holes. Compared with a reverse balance flange, the compound flange has the advantages that the problem of large relative mismatch due to the reverse balance flange being used in a small-diameter steel pipe is solved, and the bolt pretension and outer load can effectively transferred.
Description
Technical field
It is wind power generation stepped that the utility model relates to a kind of framework type, specifically, relates to a kind of composite flange.
Background technique
What framework type pylon king-post generally adopted is minor-diameter steel-tube, and its steel pipe connects the rigid flanges that adopt more.Rigid flange is limited because of flanged plate thickness, and applied bolt length is very short, if apply prestressing force, losses of prestress is larger, while being applied to framework type blower fan pylon king-post, because king-post is in tension and compression alternation state, screw retention poor performance, the easy opening of flange, can not guarantee the constant of flexural rigidity.
Be widely used in the reversed balancing flange that single tube wind power tower drum connects, though can solve screw retention problem, while being applied to the wind power generation stepped king-post connection of framework type, stiffened plate size is less, the relative misalignment causing is large, can not guarantee reliable Path of Force Transfer.
Model utility content
The technical problem that the utility model solves is to provide a kind of composite flange, has strengthened the anti-loosening property of bolt, reaches non-maintaining effect, and bolt pretension and external load can be transmitted effectively.
Technological scheme is as follows:
A kind of composite flange, comprise rigid flange and reversed balancing flange, described rigid flange comprises steel pipe, common stiffened plate and common flanged plate, described common flanged plate is fixed on the underpart of described upper steel pipe, described common stiffened plate is fixed between the outer wall of described upper steel pipe and the upper surface of described common flanged plate, and described common flanged plate has the first flange hole; Described reversed balancing flange comprises lower steel pipe, reverse stiffened plate and inverse flange plate, described inverse flange plate is fixed on the upper end portion of described lower steel pipe, described reverse stiffened plate is fixed between the upper surface of described inverse flange plate and the outer wall of described lower steel pipe, and described inverse flange plate has the second flange hole; Bolt is contained in described the first flange hole and described the second flange hole.
Further: described common flanged plate lower surface edge is provided with annular groove, described reverse stiffened plate upper-end surface arranged outside has step, and the joint of described reverse stiffened plate upper-end surface and described lower steel pipe is provided with slope.
Compared to the prior art, technique effect comprises the utility model:
The utility model is compared with rigid flange, do not increase flanged plate thickness and can increase bolt length, thereby facilitate bolt to apply pretightening force and control the size of pretightening force, to realize the constant of flexural rigidity in loading process, strengthen the anti-loosening property of bolt simultaneously, reached non-maintaining effect; The utility model, compared with reversed balancing flange, has solved reversed balancing flange and has been used on minor-diameter steel-tube and can causes larger relative misalignment problem, and bolt pretension and external load can be transmitted effectively.

In the utility model, the structure of reversed balancing flange comprises: lower steel pipe 6, reverse stiffened plate 4, inverse flange plate 5, inverse flange plate 5 is fixedly connected with (welding) in lower steel pipe 6 upper end portions, multiple reverse stiffened plates 4 are fixedly connected with (welding) between the upper surface of inverse flange plate 5 and the outer wall of lower steel pipe 6, and inverse flange plate 5 has multiple the second flange holes.
Bolt 7 is sleeved on the first flange hole of common flanged plate 3 and the second flange hole of inverse flange plate 5, and rigid flange and reversed balancing flange are linked together.
As shown in Figure 2, be the ssembly drawing of combined type flange in the utility model; As shown in Figure 3, be combined type flange longitudinal sectional drawing in the utility model.
Common flanged plate 3 lower surface edges are provided with annular groove 10; Corresponding, there is step 8 in reverse stiffened plate 4 upper-end surface arranged outside, be provided with slope 9 in the joint of reverse stiffened plate 4 upper-end surfaces and lower steel pipe 6.
When assembling, top by upper steel pipe 1 side of rigid flange at the lower steel pipe 6 of reversed balancing flange, by the end of upper steel pipe 1 along slope 9 down slidings on reverse stiffened plate 4, make steel pipe 1 align and hold out against with lower steel pipe 6, step 8 tops are now in annular groove 10, utilize step 8 and annular groove 10 that common flanged plate 3 is clamped on reverse stiffened plate 4, reverse stiffened plate 4 is alignd in the vertical direction with common stiffened plate 2, screw rod 71 is connected in the second flange hole on the first flange hole and the inverse flange plate 5 of common flanged plate 3, after screwing the nut 72 of screw rod 71, upper steel pipe 1 and lower steel pipe 6 are linked together.
