Specific implementation mode
Technical scheme of the present invention is specifically described below in conjunction with Figure of description.
Describe the detailed features and advantage of the present invention in detail in a specific embodiment below, content is enough to make any Skilled in the art realises that the technology contents of the present invention and implement according to this, and specification disclosed by this specification, weigh Profit requires and attached drawing, skilled person readily understands that the relevant purpose of the present invention and advantage.
As described above, the big direct steel cylinder of diameter 28m prolongs the longitudinal T-steels of uniformly distributed 48 grades of circumferential direction, nothing in steel cylinder Any stull, overall structure rigidity are weaker.It, will be to steel cylinder simply by the presence of smaller horizontal component in hoisting process Circularity produces bigger effect.Therefore design Hoisting Program in hoisting process the suspension centre stress of steel cylinder be only vertically to On, there cannot be inclination angle.
The present invention by Large-diameter Steel cylinder carry out Modeling Calculation, be uniformly arranged 8 lifting points in steel cylinder upper end, 8 lifting points are installed by 8 lifting lifting lugs so that steel cylinder uniform force in lifting reduces lifting deformation.So that stress It is uniformly distributed in a circumferential direction, hoisting process is only by power vertically upward, no horizontal component, in the case steel cylinder structure Meet lifting requirements.
Conventional crane is generally 1~2 gib head, and 8 suspension centres of steel cylinder are distributed on the circumference of a diameter of 28m, if 8 suspension centres of steel cylinder are directly connect with gib head, in limited altitude range, there is horizontal component in steel cylinder certainly, from And steel cylinder is caused to deform.Therefore, special hoisting bar is separately designed according to two kinds of different lifting equipments.
According to the present invention, a kind of hanging beam of octagon is designed, and makes 8 on 8 suspension centres and the steel cylinder on hanging beam It is completely the same that suspension centre opens grade size.In this way so that steel cylinder in hoisting process only in stress vertically upward, pass through Hanging beam structure eliminates horizontal component of the steel cylinder in hoisting process.
By designing two kinds of operating mode hanging beams, is not changing structure suspension centre, meeting the door machine lifting of two, internal field and code First table flotation hangs lifting requirements.
The Hoisting Program of the present invention is connected to 8 suspension centres of hanging beam upper end, phase using the steel wire rope doubling of 4 equal lengths Adjacent two suspension centres are same root steel wire rope.Crane gib head ensures each suspension centre stress equalization when hooking steel wire rope.
Connection between hanging beam and steel cylinder uses steel wire rope as short as possible, thus can reduce steel cylinder in hoisting process In shaking and the deformation that generates.
