Abstract
The utility model belongs to the auxiliary manufacture device of wind power generation equipment, in particular to an auxiliary hoisting device of a reversal balance flange tower support, which comprises a pin shaft (4), a pin shaft snap spring (4-1), a hoisting lug fixed base (5) and a hoisting lug (6), and is characterized in that the upper plane of a connecting plate (3) is machined into a fan shape, the section of the upper plane is in L shape, the outer side with a flange of the connecting plate (3) is an arc surface which has the same radius as that of a reversal balance flange outer wall, the position of the connecting plate (3), which corresponds to a reversal balance flange hole, is provided with three high-strength bolts in a penetrating way, and the lower ends of the high-strength bolts (2) are fixed by a high-strength bolt and but (1). In the auxiliary hoisting device of the reversal balance flange tower support, the shearing force formed by radial pulling force formed by a steel rope can be overcome by the connecting plate, and the high-strength can not bear the shearing force, so that the hoisting is safe.
Description
Technical field
The utility model belongs to wind power plant and makes accessory appliances, particularly a kind of reverse balance flange tower hoisting auxiliary device.
Background technology
Managing tower reverse balance flange pylon is a kind of later-model wind power tower, be that traditional forging face-flange is transformed into a large-scale hardware, thereby reduced the manufacturing cost of wind power equipment, be subjected to pursuing of the wind-powered electricity generation investor, be subjected to the shearing problem but traditional suspender can't resolve the suspender bolt when pylon is installed.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of suspender bolt not to be subjected to shearing, can guarantee to lift safe reverse balance flange tower hoisting auxiliary device.
The technical scheme that the utility model technical solution problem adopts is: oppositely balance flange tower hoisting auxiliary device comprises bearing pin, bearing pin jump ring, hanger permanent seat, hanger, the last plane that is characterized in connecting panel is made fan-shaped, transversal surface is L shaped, the flanged lateral surface of connecting panel is the arc surface with the same radian of reverse balance flange outer wall, install three high strength bolts with the reverse corresponding position of balance flange hole on the connecting panel, the lower end of high strength bolt is fastening with the high strength bolt nut.
The beneficial effects of the utility model are: oppositely balance flange tower hoisting auxiliary device is overcome by the connecting panel flange by the shearing of the radial pull formation of cable wire, and high strength bolt is not subjected to shearing, can guarantee to lift safety.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is reverse balance flange tower hoisting auxiliary device structural front view.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
Among the figure, 1-high strength bolt nut; The 2-high strength bolt; The 3-connecting panel; The 4-bearing pin; 4-1-bearing pin jump ring; 5-hanger permanent seat; The 6-hanger; The reverse balance flange of 7-outer wall; The reverse balance flange of 8-balance block; The reverse balance flange of 9-butt flange.
The specific embodiment
Embodiment, with reference to accompanying drawing 1～3, oppositely the last plane of the connecting panel 3 of balance flange tower hoisting auxiliary device is made fan-shaped, transversal surface is L shaped, connecting panel 3 flanged lateral surfaces are the arc surfaces with the same radian of reverse balance flange outer wall, install three high strength bolts 2 with the reverse corresponding position of balance flange hole on the connecting panel 3, the lower end of high strength bolt 2 is fastening with the high strength bolt nut, on connecting panel 3, be symmetrically welded two hanger permanent seats 5, bearing pin 4 activities be installed on two hanger permanent seats 5 and hanger 6 in the hole, spacing fixing with bearing pin jump ring 4-1.
Oppositely the working process of balance flange tower hoisting auxiliary device is: the upper surface that the flange of connecting panel 3 closely is adjacent to reverse balance flange outer wall 7, the lower plane of connecting panel 3 contacts with the upper surface of reverse balance flange balance block 8, high strength bolt 2 passes reverse balance flange butt flange 9, tighten high strength bolt nut 1, crane cable wire symmetry is suspended on the hanger 4, and hoisting to guarantee to lift safety.
