Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1, fig. 2 and fig. 5, the lifting device for lifting flange-connected steel framework of the present invention comprises a lifting beam 1 and lifting flaps 2 respectively disposed at two ends of the lifting beam 1. The hanger 2 includes a hanger plate 21 and a flange connecting plate 22, and the flange connecting plate 22 is vertically disposed on the hanger plate 21, so that the flange connecting plate 22 of the hanger 2 can be closely attached to the side of the flange 51 when the steel framework 5 is hoisted. The flange connecting plate 22 is provided with a through hole 212, and the through hole 212 is used for installing a connecting bolt 6, so that the flange 51 and the lifting flap 2 are fixed through the connecting bolt 6, the steel framework 5 can be conveniently and quickly fixed, and a lifting point cannot slide in the lifting process. The number of the through holes 212 may be one or more, and is set according to the actual situation. The hanging plate 21 is connected with the hanging beam 1 through the hanging rope 3, wherein the hanging rope 3 can be directly wound on the hanging beam 1. The hoisting point is convenient to fix and cannot slide, so that the flange connection type steel framework is more convenient to hoist, the time for binding the steel wire rope by the hoisting steel framework is saved, the hoisting leveling of the steel framework is easier, the steel pipe frame cannot have unbalance risk caused by the sliding of the hoisting point in the hoisting process, and the hoisting efficiency and the hoisting safety coefficient are also improved.
The flange connection plate 22 may be one or more pieces and is provided on the hanger plate 21 by bolting or welding, respectively. Specifically, as shown in fig. 2, there are two flange connection plates 22, the two flange connection plates 22 are respectively welded to the hanger plate 21, and a flange clamping groove 23 is formed between the two flange connection plates 22. When the steel framework 5 is hoisted, a part of the flange 51 can be clamped into the flange clamping groove 23 and fixed through the two flange connecting plates 22, so that the steel framework can be more stably fixed, the flange 51 can be better prevented from deforming during hoisting, and the strength of a lifting bar is higher.
As shown in fig. 3, the hanger plate 21 is disposed in a circular arc shape, and the flange connection plate 22 is disposed inside the arc surface of the hanger plate 21. Compared with the case that the hanger plate 21 is a flat plate, the distance from each through hole 212 on the flange connecting plate 22 to the hanger plate 21 is approximately consistent, and the flange connecting plate 22 is stressed more uniformly and is less prone to deformation during hoisting.
The hanging beam 1 can be a steel pipe, an I-steel, a truss and the like. As shown in fig. 1, 4 and 5, the hanging beam 1 is formed by welding two parallel i-beams 12, and lifting lugs 11 are respectively arranged at two ends of the hanging beam 1. The lifting lug 11 is formed by a steel plate 13 welded between two i-shaped steels 12 of the lifting beam 1, an upper lifting hole 131 is arranged at the upper end of the steel plate 13, a lower lifting hole 132 is arranged at the lower end of the steel plate 13, and the lifting rope 3 is connected with the lifting beam 1 through the lower lifting hole 132. The steel plate 13 is welded between the two i-beams 13 of the hanging beam 1, and the concrete realization form in the figure is that a vertical groove is arranged between the two i-beams 12 of the hanging beam 1, and the steel plate 13 is inserted into the vertical groove and is welded with the two i-beams. During hoisting, the upper hoisting hole 131 is used for connecting a hoisting rope in a penetrating way with the crane hook 7, and the steel framework usually weighs tens of tons, so that the weight of the steel framework 5 is mainly directly transmitted to the crane by the lifting lug 11, namely the steel plate 13, and the hoisting beam 1 mainly plays a role in fixing the lifting lug, so that the bending resistance requirement on the hoisting beam 1 is reduced, the manufacturing cost of the hoisting tool can be saved, and the lifting lug 11 is not easy to deform in the hoisting process.
The number of the lifting flaps 2 at each end of the lifting beam can be one or more, and the arrangement can be more practical. Because the steel framework generally is four stands, the lifting flap quantity of 1 every end of hanging beam in figure 1 is 2, can guarantee like this to set up a lifting flap on every stand of steel framework.
Specifically, in fig. 1, the lifting device further includes fixed pulleys 4 respectively disposed at two ends of the lifting beam 1, the fixed pulleys 4 are connected to the lifting beam 1 through the lower lifting holes 132, two lifting tabs 2 at each end of the lifting beam 1 are respectively disposed at two ends of the lifting rope 3 (the lifting tabs 2 are connected to the lifting rope through the lifting plates 21), and the lifting rope 3 is wound around the fixed pulleys 4. Therefore, the relative positions of the two lifting flaps at each end of the lifting beam can be conveniently adjusted during lifting, so that the lifting is facilitated. Of course, the lifting rope 3 can be inserted directly into the lower hanging hole 132, but the friction between the lifting rope 3 and the lower hanging hole 132 is large, so that the lifting rope is not easy to pull.
As shown in fig. 5, when the steel frame 5 is hoisted, a flange 51 at an appropriate position is selected on the steel frame 5, a part of the flange 51 is inserted into the flange holding groove 23, the flange 51 and the hanger 2 are fixed by the connecting bolt 6, the upper lifting hole 131 of the lifting lug 11 is connected to the crane hook 7 by a lifting rope, and the steel frame is tried to be hoisted and leveled and finally hoisted in place. The hoisting point is convenient to fix and cannot slide, so that the flange connection type steel framework is more convenient to hoist, the time for binding the steel wire rope by the hoisting steel framework is saved, the hoisting leveling of the steel framework is easier, the steel pipe frame cannot have unbalance risk caused by the sliding of the hoisting point in the hoisting process, and the hoisting efficiency and the hoisting safety coefficient are also improved.
