Detailed description of the invention
By reference to the accompanying drawings the present invention is described in further detail by the following examples.
Refer to Fig. 1 and Fig. 2, in some embodiments, the beam body along continuous straight runs of arc equalizing bar is curved, and the suspension centre of described arc equalizing bar is arranged the arc that is hung arc cylindrical shell consistent (arc herein all refers to non-full circle) with many member compositions.
In an embodiment, the suspension centre of described arc equalizing bar is consistent with the member that is hung arc cylindrical shell with on installation site in quantity.,, in this embodiment, hung each member of arc cylindrical shell to there being a suspension centre, and mutual alignment relation is one to one.
But, in the situation that meeting safety, do not get rid of arc equalizing bar the multiple members that link together are executed and hung with a suspension centre.
As shown in Figure 1, Figure 3 and Figure 4, in preferred embodiment, the beam body of described arc equalizing bar is joined and forms successively by a series of box-like body and inner side gussets with arcuate flanks.A benefit of this design is conveniently for actual needs change beam body size, to comprise and to increase or reduce suspension centre.
As shown in Fig. 2, Fig. 4-Fig. 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, lifting main shaft 1 is through 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 by the nut fixation on it.As shown in Figure 5, preferably, arc equalizing bar upper end is provided with pulley pallet 2, location, guiding while lifting for pulley.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), the present embodiment has been cancelled suspension hook and the shackle on equalizing bar top, pulley is directly connected with the main otic placode of equalizing bar by lifting main shaft, reduce top and connected distance, can save like this suspension hook, steel rope, shackle and be connected needed space with equalizing bar.
In an embodiment, as the hanger that hangs below hoist cable, arc equalizing bar top is distributed with and the paired small ear plate 12 of member equivalent amount by arc, and makes the layout of small ear plate consistent with the radian that arc barrel components 11 distributes.
As shown in Figure 5-Figure 8, this arc equalizing bar inside is provided with the wire rope sling passage 8 that runs through up and down equalizing bar, respectively there is a small ear plate 12 hoist cable channel exit both sides in the upper plane of arc equalizing bar, as the hanger of the wire rope sling 9 of suspension element, little axle 7 cross-ties are arranged in the little axle mounting hole of every a pair of small ear plate 12.Lifting wire rope sling 9 passes by hoist cable passage, is fixed on little axle 7.Under equalizing bar, can hoist cable be hung to member 11 with quilt by shackle 10 is connected.Shackle can be general lockset.This design, lifting wire rope sling 9 passes by the hoist cable passage 8 of equalizing bar inside, the length of hoist cable 9 is hidden in the middle of arc equalizing bar to greatest extent, for 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 to equalizing bar top, is also convenient to unload steel rope.
As shown in Figure 1, Figure 3 and Figure 4, wire rope sling passage is preferably arranged on the line of centers of equalizing bar longitudinal (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, also solve the problem that facilitates rope unloading simultaneously.
In a practical application example, loop wheel machine, arc equalizing bar and to be hung the concrete installation process of arc cylindrical shell as follows:
(1) member of the arc cylindrical shell assembled some laths being formed (arc cylindrical shell conventionally by lath splicing in specific frock in advance that for example approximately many single-pieces of 20 ~ 30m are very long, close up form) be connected with cable wire end 9 accordingly by shackle 10 one by one, as treating hanging piece 11;
(2) arc equalizing bar 5 is placed in above the frock of assembled arc cylindrical shell;
(3) each cable wire end 9 is connected with the little axle 7 being arranged on small ear plate 12 through hoist cable passage 8 in the middle of corresponding arc equalizing bar;
(4) loop wheel machine pulley 3 is placed on arc equalizing bar 5 by pulley pallet 2 guiding;
(5) lifting main shaft 1, successively through the hole for hoist of the main otic placode 6 of arc equalizing bar and the hole for hoist of pulley 3, is connected loop wheel machine pulley 3 with arc equalizing bar 5, and the nut screwing clamping on it is firm to install.
After above-mentioned steps completes, check and just can implement lifting after errorless.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
