The specific embodiment
Below combine accompanying drawing that the present invention is further specified through embodiment.
See also Fig. 1 and Fig. 2, in some embodiment, the beam body along continuous straight runs of arc equalizing bar is curved, and the suspension centre of said arc equalizing bar arranges that the quilt of forming with many members hangs the arc consistent (arc among this paper all refers to non-full circle) of arc cylindrical shell.
In an embodiment, the suspension centre of said arc equalizing bar is consistent with the member that is hung the arc cylindrical shell on quantity and installation site.That is, in this embodiment, each member that is hung the arc cylindrical shell is to should there being a suspension centre, and the mutual alignment relation is one to one.
Yet, satisfying under the situation of safety, do not get rid of the arc equalizing bar and a plurality of members that link together are executed with a suspension centre hung.
Like Fig. 1, Fig. 3 and shown in Figure 4, in preferred embodiment, the beam body of said arc equalizing bar is joined successively by a series of box-like body with arcuate flanks and inboard gusset and forms.Benefit of this design-calculated is that it is big or small conveniently to change the beam body to actual needs, comprises increasing or reduce suspension centre.
Like Fig. 2, Fig. 4-shown in Figure 6; At two places separated by a distance, arc equalizing bar top; Every place is provided with a pair of main otic placode 6 to upper process, and lifting main shaft 1 passes the hole for hoist of main otic placode 6 and the hole for hoist of loop wheel machine pulley 3, directly main otic placode 6 is connected with loop wheel machine pulley 3; Thereby loop wheel machine pulley 3 is connected with arc equalizing bar 5, and through the nut fixation on it.As shown in Figure 5, preferably, arc equalizing bar upper end is provided with pulley pallet 2, and location, guiding are used when supplying the pulley lifting.Loop wheel machine pulley 3 matches with loop wheel machine steel rope 4.
Equalizing bar in the past all passes through suspension hook, steel rope, shackle and is connected with loop wheel machine pulley (general pulley is made as one with suspension hook); Present embodiment has been cancelled the suspension hook and the shackle on equalizing bar top; Pulley directly is connected with equalizing bar master otic placode through the lifting main shaft; Reduced top and connected distance, can save suspension hook, steel rope, shackle like this and be connected needed space with equalizing bar.
In an embodiment, as the hanger of suspension below hoist cable, arc equalizing bar top is distributed with the paired small ear plate 12 with the member equivalent amount by arc, and makes that the layout of small ear plate is consistent with the radian of arc cylindrical shell member 11 distributions.
Like Fig. 5-shown in Figure 8; This arc equalizing bar set inside has the wire rope sling passage 8 that runs through equalizing bar up and down; Respectively there is a small ear plate 12 the hoist cable channel exit both sides on plane on the arc equalizing bar; As the hanger of the wire rope sling 9 of suspension element, little axle 7 cross-ties are installed in each little axle mounting hole to small ear plate 12.Lifting wire rope sling 9 passes through the hoist cable passage, is fixed on the little axle 7.Can hoist cable be hung member 11 with quilt through shackle 10 under the equalizing bar is connected.Shackle can be general lockset.This design; Lifting wire rope sling 9 passes through equalizing bar in-to-in hoist cable passage 8, the length of hoist cable 9 is hidden in the middle of the arc equalizing bar to greatest extent, for the lifting space has been saved in the lifting of member 11; Shorten hoisting height, therefore can reduce the operating altitude of loop wheel machine.Suspension centre is located at the equalizing bar top, also is convenient to unload steel rope.
Like Fig. 1, Fig. 3 and shown in Figure 4, the wire rope sling passage preferably is arranged on the line of centers of equalizing bar vertical (being horizontal direction).
In preferred embodiment, adopt aforementioned arrangements that the upper and lower lifting of equalizing bar is reduced the distance simultaneously, can more effectively solve and hang high limited problem, the while has also solved and has made things convenient for the discharged problem of rope.
In a practical application example, loop wheel machine, arc equalizing bar and to be hung the concrete installation process of arc cylindrical shell following:
(1) will be the arc cylindrical shell that forms of the good some laths of assembly unit member (the arc cylindrical shell usually by the very long lath splicing on specific frock in advance of many single-pieces of for example about 20 ~ 30m, close up form) be connected with cable wire end 9 accordingly through shackle 10 one by one, as treating hanging piece 11;
(2) arc equalizing bar 5 is placed the frock top of assembly unit arc cylindrical shell;
(3) the little axle 7 on each cable wire end 9 passes the middle hoist cable passage 8 of corresponding arc equalizing bar and is installed in small ear plate 12 is connected;
(4) loop wheel machine pulley 3 places on the arc equalizing bar 5 through pulley pallet 2 guiding;
(5) lifting main shaft 1 passes the hole for hoist of arc equalizing bar master otic placode 6 and the hole for hoist of pulley 3 successively, loop wheel machine pulley 3 is connected with arc equalizing bar 5, and the nut screwing clamping on it is firm to install.
After above-mentioned steps is accomplished, check and just can implement to lift after errorless.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
