The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

With reference to Fig. 1, Fig. 2, Fig. 3 and shown in Figure 5, present embodiment is exempted from the large cylinder suspender 10 of operation in the tube, be used for being used handling large cylinder 20 with weight-lifting equipment, comprise many crossbeams 11, each crossbeam 11 is connected by its place, end each other and forms plane framework 12, the place of being connected, end of crossbeam 11 is connected with the vertical suspension rod 13 of rigidity, suspension rod 13 is lifted by crane in the centre by the barrel clamping that is used for large cylinder 2, and hang leg 14 in being oppositely arranged and hang leg 15 outward and constitute, in, hang leg 14 outward, 15 top is fixed with one, the bottom is equipped with the 16 coaxial settings of large cylinder connecting bore 16, two large cylinder connecting bores.

Particularly, because large cylinder is the harbour construction member, weight-lifting equipment is a crane ship in the present embodiment, hoisting wirerope 4 ends that crane ship gib head 3 is hung link to each other with the place of being connected, crossbeam 11 end of present embodiment large cylinder suspender 10, each end of crossbeam 11 is connected and locates to link to each other with suspension rod 13, suspension rod 13 links to each other with lifting hole(eyelet) 21 places of large cylinder 20 on large cylinder 20, realizes the purpose of handling.Crossbeam 11 and suspension rod 13 adopt steel material to make, guarantee its strength and stiffness, can be connected by the mode of welding between each crossbeam 11 and form plane framework 12, plane framework 12 can be quadrangle, triangle or other polygon, decides with the diameter of lifted by crane large cylinder 20.Continuous position, suspension rod 13 tops is identical to the distance of lifting hole(eyelet) 21 with large cylinder 20 upper surfaces to the distance of its bottom large cylinder connecting bore 16, then suspender 10 is placed on the large cylinder, two large cylinder connecting bores 16 are just concentric with lifting hole(eyelet) 21, with bearing pin III 7 pass successively outer hang large cylinder connecting bore 16 on the leg 15, lifting hole(eyelet) 21, in hang large cylinder connecting bore 16 on the leg 14, then spacing the hanging outside of bearing pin prevented on the leg 15 that bearing pin from coming off voluntarily and promptly installs that unloading process in contrast; If during large cylinder 20 weight front, rear, left and right overbalances, do suitable adjustment as long as will hang over the length of hoisting wirerope 4 on the crane ship gib head 3, weight general goal hoisting wirerope 4 length shorten a bit less, hoisting wirerope 4 length are constant everywhere for other, can realize the steady lifting of weight overbalance large cylinder.In addition, the inside and outside mode that is connected of hanging between

leg

14,15 tops can be chosen in the mode of welding a plate 19 between the two, or adopt alternate manner, and present embodiment does not limit this.

The large cylinder suspender 10 of exempting from operation in the tube for ease of present embodiment connects hoisting wirerope 4 and suspension rod 13, the place of being connected, end of crossbeam 11 is installed with and connects termination 17, the top that connects termination 17 connects crane ship, hinged inside and outside top of hanging

leg

14,15, bottom by hoisting wirerope 4.

Connect termination 17 and comprise base plate 171 and be installed in biside plate 172 on base plate 171 relative edges, be provided with coaxial pin-and-hole 173 on the biside plate 172 relatively, have on the base plate 171 and hang leg hinge hole 174, inside and outsidely hang that correspondence has hinge hole 18 on the

leg

14,15.

In order to cooperate the closure that is subjected to force direction and suspension rod 13 tops and large cylinder 20 of hoisting wirerope 4, pin-and-hole 173 and the axis normal of hanging leg hinge hole 174, the axis that promptly hangs leg hinge hole 174 is about the circle diameter direction of large cylinder 20, and the axis direction of pin-and-hole 173 is about the tangent to periphery direction of large cylinder 20.Then when connecting termination 17 connection hoisting wireropes 4, adopt bearing pin I 5 to pass closed stomidium and another pin-and-hole 173 of pin-and-hole 173 of lifting, hoisting wirerope 4 successively, lock bearing pin I 5 then and get final product; Connect that the bottom of termination 17 is hinged inside and outsidely hung leg at 14,15 o'clock, adopt bearing pin II 6 pass successively outer hang on hinge hole 18 on the leg 15, the base plate 171 hang leg hinge hole 174 and in hang hinge hole 18 on the leg 14, lock bearing pin II 6 then and get final product.

With reference to shown in Figure 4, when lifting finishes, suspender 10 is placed on crane ship deck or fabrication yard when depositing on the ground, because suspension rod 13 is hinged between the termination 17 with being connected, then all suspension rods 13 are easy to rotate 90 degree to same direction on the suspender 10, greatly reduce depositing highly and size of suspender 10, help safety in production, realize safe storage.

It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
