Description
Technical field
The utility model relates to single supported beam drag-line technique for fixing field, particularly relates to a kind of jib drag-line anchor fitting.
Background technology
In order to expand operating radius, the jib on crane extends longer, makes rotary operation convenient, but because unsettled extension is longer, the stability of jib reduces, and load-carrying capacity declines, therefore, the head of drag-line to jib must be adopted to lift, in order to avoid jib deforms when lifting.
The cantilever design of the stay cable type that single bearing pin is fixed that what general jib adopted is, intensity is low, poor reliability, needs to improve.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of jib drag-line anchor fitting, improves intensity and reliability.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of jib drag-line anchor fitting, comprise: head joint lifting jib and two center shafts, described two center shafts are symmetricly set on the both sides of head joint lifting jib, the outside end of described two center shafts is respectively arranged with adapter plate, described two center shafts are arranged with support beam respectively, the two ends of described support beam are symmetrically arranged with drag-line bearing pin, described drag-line bearing pin is arranged with annular sleeve respectively, the cylindrical of described annular sleeve is provided with a circle groove, suspension cable is surrounded with in described groove.
In the utility model preferred embodiment, the axes coincide of described two center shafts.
In the utility model preferred embodiment, the middle part of described support beam is provided with a centre hole corresponding with center shaft, is provided with bearing between described centre hole and center shaft.
In the utility model preferred embodiment, described support beam lays respectively at adapter plate and head and saves and lift between jib.
In the utility model preferred embodiment, described head joint lifting jib is provided with two strut bars to downward-extension, the bottom end of described strut bar is respectively arranged with leading sheave, adopts fixed pin shaft to be connected between the bottom of described strut bar and the top of leading sheave.
The beneficial effects of the utility model are: a kind of jib drag-line anchor fitting that the utility model is pointed out, adopt four groups of suspension cables to lift, intensity is high, devise rotary support beam especially, improve anti-shake performance and stability in use, manufacture easy, with low cost, reliability is high.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of jib drag-line of the utility model anchor fitting one preferred embodiment;
Fig. 2 is that the B-B of Fig. 1 is to cutaway view Amplified image.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 2, the utility model embodiment comprises:
A kind of jib drag-line anchor fitting, comprise: head joint lifting jib 1 and two center shafts 2, head joint lifting jib 1 adopts welded steel to make, sound construction, described two center shafts 2 are symmetricly set on the both sides of head joint lifting jib 1, the outside end of described two center shafts 2 is respectively arranged with adapter plate 3, described two center shafts 2 are arranged with support beam 5 respectively, the two ends of described support beam 5 are symmetrically arranged with drag-line bearing pin 4, described drag-line bearing pin 4 is arranged with annular sleeve 6 respectively, the cylindrical of described annular sleeve 6 is provided with a circle groove, the axes coincide of described two center shafts 2, symmetry is good, stressed more even, promote the stability used.
Described a kind of jib drag-line anchor fitting uses flexibly, and stability is high, and the middle part of described support beam 5 is provided with a centre hole corresponding with center shaft 2, is provided with bearing 21 between described centre hole and center shaft 2.Under the support of bearing 21, support beam 5 can wave, and convenient installation is fixed, and improves anti-shake performance and stability in use.
Further, described support beam 5 lays respectively at adapter plate 3 and head and saves and lift between jib 1.Adapter plate 3 is fixed on the end of center shaft 2, limits the longitudinal travel of support beam 5, and assembling is simple, improves the stability of structure.
Further, described head joint lifting jib 1 is provided with two strut bars 8 to downward-extension, the bottom end of described strut bar 8 is respectively arranged with leading sheave 9, adopts fixed pin shaft 81 to be connected, assemble and change more convenient between the bottom of described strut bar 8 and the top of leading sheave 9.
Further, suspension cable 7 is surrounded with in described groove.Four groups of suspension cables 7, improve the load-carrying capacity of head joint lifting jib 1, and arbitrary suspension cable 7 fracture can't cause integrally-built damage, and reliability is higher.
In sum, a kind of jib drag-line anchor fitting that the utility model is pointed out, intensity is high, good reliability, manufactures simple, applied widely.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
