[0004] In the construction of existing thermal power plants, the installation of the roof girder mainly relies on the crane to realize the hoisting work of the upper and lower girders, but because the weight of the upper and lower girders is extremely large, and the center of gravity is close to the bottom plate, it is extremely difficult to turn over with the crane alone , there is also a lack of corresponding auxiliary tools for turning over the roof girder

Embodiment Construction
[0018] A roof beam overturn bracket, comprising a support frame 1 with a cross-sectional shape of an acute triangle, one triangular side of the support frame is a bottom edge 2, the bottom edge is attached to the bottom of the roof beam bottom plate 104, and the bottom edge extends transversely to the vertical direction of the roof beam bottom plate Outside the projection range, a vertically arranged side plate 3 is installed, and a horizontal clamping plate 4 is installed on the side plate facing the roof beam vertical plate 103, and the distance between the clamping plate and the bottom edge is adapted to the thickness of the roof beam bottom plate , and the bayonet 5 surrounded by the clamping plate, the side plate and the bottom is clamped tightly with the side of the roof beam bottom plate.
[0019] like image 3 , 4 As shown, fix the overturning bracket on the bottom of the roof beam (upper beam), and the bayonet formed by the clamping plate, side plate and bottom edge ...

The invention discloses a top plate beam overturning support and method. The overturning support comprises a triangular supporting frame. The bottom edge of the supporting frame and the side edge of a top plate beam bottom plate are mutually clamped through a clamping opening defined by a clamping plate, a side plate and a bottom edge, and the corner, opposite to the bottom edge, of the supporting frame abuts against the ground. When the overturning support is utilized for overturning the top plate beam, the top plate beam is hoisted firstly, the overturning support is arranged on the top plate beam bottom plate, then, the top plate beam is placed and laterally inclines with the corner of the overturning support as the fulcrum, the laterally-inclining top plate beam is hoisted from the other end of the top plate beam, and hoisting is conducted after overturning. The structure of the overturning support is extremely simple, but the structure strength is high, the top plate beam which is hugely heavy can be effectively supported, and operation convenience is greatly improved. According to the overturning method, the requirement for equipment can be effectively lowered, meanwhile, the operation process of the overturning method is extremely simple and feasible, the top plate beam overturning difficulty is lowered, and meanwhile the top plate beam overturning operation convenience and accuracy are improved.
Description
technical field [0001] The invention relates to equipment for assisting heavy workpieces in vertical overturning, in particular to a roof girder overturning support and a method for using the support to overturn the roof beam. Background technique [0002] The roof beam, also known as the large plate beam, is a kind of boiler stress beam often used in conventional thermal power plants. Its structure is as follows figure 1 As shown, the upper beam 101 and the lower beam 102 including the upper and lower relative equipment, the bottom of the upper beam and the top of the lower beam are fixedly connected as one; and the structure of the upper beam and the lower beam is as follows figure 2 As shown, they all include a vertically arranged vertical plate 103, and the two ends and the middle of the vertical plate are sequentially equipped with a horizontally arranged bottom plate 104, a rib plate 105 and a connecting plate 106 with decreasing lengths, wherein the connecting plate ...
