Abstract
The utility model discloses a longitudinal hoisting device of a full-gyration tug. The longitudinal hoisting device comprises a plurality of long slings, a plurality of short slings and a plurality of lifting rings symmetrically arranged at the two sides of the full-gyration tug, wherein the longitudinal center line of the full-gyration tug is parallel with a shipbuilding special crane traveling track; each lifting ring is connected with a connecting shackle; an upper trolley lifting hook is connected with one group of lifting rings at one end of one side of the full-gyration tug through two first short slings, respectively; two long slings on which a lower trolley lifting hook is suspended are connected with the middle parts of the corresponding second short slings through the connecting shackles, respectively; and the two ends of each second short sling are connected with one group of lifting rings at one end of the other side of the full-gyration tug through the connecting shackles, respectively. The longitudinal hoisting device lifts the full-gyration tug into water by using the shipbuilding special crane and the special hoisting device; and the full-gyration tug can be built at the horizontal place, therefore, the process difficulty of building is reduced, and the utilization rate of the shipbuilding special crane can be increased and the time of the small-sized tug occupying the shipbuilding special berth is educed.
Description
Technical field
The utility model relates to a kind of lifting appliance of launching, and Z-drive tug vertical overhead hoist in especially a kind of harbour belongs to the shipbuilding technical field.
Background technology
The full circle swinging berthing tug has flexible operation, can carry out by any direction the characteristics of motion of ship, is widely used in the harbour and carries out the large ship harbour by various operations such as the assistance of slipping from alongside, fire-fighting, pilotages.After Z-drive tug is built on the coast and is finished, usually adopt the devices such as slideway, air bag that towboat is moved in the water, when adopting under the slideway water, mainly utilize Z-drive tug from the downslide component that focuses on the runway, and by means of special-purpose sanitation with the Z-drive tug slippage in water, the slideway manufacturing cost is high, and is seriously polluted, wastes time and energy during the boats and ships sliding launch.When adopting air bag launching, mainly utilize the characteristics of still rolling easily after the low inflation pressure of air bag, large loaded area and the large deformation, under the traction of accessory equipment, make boats and ships slowly slip in the water, complex operation, there is certain potential safety hazard in the easy explosion of air bag.
Summary of the invention
The purpose of this utility model provides a kind of efficient and convenient, safe and reliable vertical overhead hoist of Z-drive tug and utilizes the method for water under this device handling Z-drive tug.
The utility model is achieved by the following technical programs:
The vertical overhead hoist of a kind of Z-drive tug, comprise several long hoist cables, several drop shot rope and be symmetricly set on several suspension ring of Z-drive tug two topsides, Z-drive tug longitudinal centerline and shipbuilding special purpose crane walking parallel track, two one group of intervals of described suspension ring are fixed on the two ends of Z-drive tug topside, each suspension ring is connected with joining shackle, trolley lifting hook is positioned at the below of lower trolley lifting hook on shipbuilding special purpose crane two platforms, and trolley lifting hook is connected with one group of suspension ring of Z-drive tug one topside one end by two the first drop shot ropes respectively on each; Two long hoist cables that trolley lifting hook hangs under the shipbuilding special purpose crane are continuous with corresponding the second drop shot rope middle part by joining shackle respectively, and the second drop shot rope two ends are connected by one group of suspension ring of joining shackle with an end of another topside of Z-drive tug respectively.
The purpose of this utility model can also further realize by following technical measures.
The vertical overhead hoist of aforesaid Z-drive tug, wherein said suspension ring are separately positioned on Z-drive tug deck, bulwark and side plating junction, between the inboard suspension ring of each topside two ends suspension ring group of boats and ships apart from a the distance between the trolley lifting hook on two during greater than free state, distance b is 0.5～0.6 times of captain L between the outside suspension ring of each topside two ends suspension ring group of boats and ships, and the distance c between each suspension ring group two suspension ring equals two floor spaces of Z-drive tug hull.
The utility model adopt shipbuilding special purpose crane and special-purpose overhead hoist with longitudinally handling of Z-drive tug to water, can build Z-drive tug at horizontal field, reduce the build process difficulty, also can improve the degree of utilization of shipbuilding special purpose crane, reduce skiff to the taking of the special-purpose building berth of shipbuilding, and opened up the launching method of building skiff at the other fitting-out platform of large-scale building berth.
Advantage and disadvantage of the present utility model will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that enlarged drawing is looked on the left side of Fig. 1;
Fig. 3 is the I section enlarged drawing of Fig. 2.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Such as Fig. 1～shown in Figure 3, shipbuilding special purpose crane 1 by rail supported on large-scale building berth 2, under the large ship 5 that shipbuilding special purpose crane 1 is being built across large-scale building berth 2 left sides and the treating on right side on the Z-drive tug 3 of water.Shipbuilding special purpose crane 1 load-carrying ability of present embodiment is 400 tons, heavily about 380 tons of Z-drive tug 3.The vertical overhead hoist of Z-drive tug of the present invention comprises two long hoist cables 41,4 the first drop shot ropes 42,2 the second drop shot ropes 43 and be symmetricly set on 8 suspension ring 44 of 3 liang of topsides of Z-drive tug, Z-drive tug 3 longitudinal centerlines are parallel with shipbuilding special purpose crane walking track 11,44 two one group of intervals of suspension ring are welded in the two ends of Z-drive tug 3 topsides, each suspension ring 44 is connected with joining shackle 45, trolley lifting hook 11 is positioned at the below of lower trolley lifting hook 12 on two platforms of shipbuilding special purpose crane 1, and upper trolley lifting hook 11 and lower trolley lifting hook 12 are and can hang two T shape suspension hooks that hang bundle.Trolley lifting hook 11 is connected with one group of suspension ring 44 of Z-drive tug 3 one topsides one end by two the first drop shot ropes 42 respectively on each; Two long hoist cables 41 of lower trolley lifting hook 12 suspensions link to each other with two the second drop shot rope 43 middle parts by joining shackle 45 respectively, and two the second drop shot rope 43 two ends are connected with one group of suspension ring 44 of an end of Z-drive tug 3 another topsides by joining shackle 45 respectively.3 liang of topsides of Z-drive tug are provided with 4 suspension centres altogether, and the one topside hangs 2 suspension centres by the first drop shot rope 42 respectively with two that are positioned at lower upper trolley lifting hooks 11; Another topside hangs in addition 2 suspension centres with the lower trolley lifting hook 12 that is positioned at eminence by long hoist cable 41, the second drop shot rope 43, and the height combination by 3 suspension hooks cooperates length hoist cable and joining shackle 45, can firmly lift by crane Z-drive tug 3.Lower trolley lifting hook 12 is positioned at the angle that eminence is hoist cable in order to reduce to lift by crane, thereby reduces the stressed of hoist cable.
