Further improvement of the utility model is: be wound with variable-amplitude steel wire rope on the luffing range of cantilever support winch, variable-amplitude steel wire rope passes Shears top pulleys group and jib head assembly pulley on described luffing suspension hook, be wound with main hoist rope on the main hoister winch, main hoist rope passes Shears top pulleys group and jib head assembly pulley on main suspension hook, be wound with secondary hoist rope on the secondary hoister winch, secondary hoist rope passes Shears top pulleys group and jib head assembly pulley on secondary suspension hook.
Further improvement of the utility model is: the root of Shears is connected root with jib all be to be connected with turn table top by hinge.
The utility model compared with prior art has the following advantages: the utility model novel structure, external form is succinct, compact conformation, do not take between deck space fully, can realize the several work operating mode, strong adaptability has also improved the service efficiency of offshore platform, is a kind of weight-lifting equipment with broad prospect of application.
Description of drawings:
Fig. 1 is front view of the present utility model;
Fig. 2 is birds-eye view of the present utility model.
Among the figure: the secondary hoister winch of 1-pedestal, 2-rotary supporting device, 3-turn table, 4-luffing range of cantilever support winch, 5-master's hoister winch, 6-, 7-Shears, 8-master's hoist rope, 9-pair hoist steel cable, 10-variable-amplitude steel wire rope, 11-Shears top pulleys group, 12-jib, 13-jib head assembly pulley, 14-master's suspension hook, the secondary suspension hook of 15-, 16-shoe, 17-spud leg, 18-main deck, 19-driver's cab, 20-machine room, 21-luffing suspension hook.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used for explaining the utility model, does not consist of the restriction to the utility model protection domain.
It is a kind of large-scale around stake formula offshore platform hoisting crane that Fig. 1 and Fig. 2 show the utility model, comprise the spud leg 17 that is inserted on the main deck 18, cover has shoe 16 on the spud leg 17, shoe 16 places on the main deck 18, shoe 16 is provided with pedestal 1, pedestal 1 is provided with rotary supporting device 2, rotary supporting device 2 tops are provided with turn table 3, one side of turn table 3 is provided with driver's cab 19 and machine room 20, be provided with successively luffing range of cantilever support winch 4 on the turn table 3, main hoister winch 5, secondary hoister winch 6, also be provided with Shears 7 on the turn table 3, the top of Shears 7 is provided with Shears top pulleys group 11, turn table 3 is connected with jib 12, the root that the root of Shears 7 is connected with jib all is to be connected with turn table 3 tops by hinge, the top of jib 12 is provided with jib head assembly pulley 13, the below, top of jib 12 is provided with main suspension hook 14, secondary suspension hook 15 and luffing suspension hook 21, be wound with variable-amplitude steel wire rope 10 on the luffing range of cantilever support winch 4, variable-amplitude steel wire rope 10 passes Shears top pulleys group 11 and jib head assembly pulley 13 on luffing suspension hook 21, be wound with main hoist rope 8 on the main hoister winch 5, main hoist rope 8 passes Shears top pulleys group 11 and jib head assembly pulley 13 on main suspension hook 14, be wound with secondary hoist rope 9 on the secondary hoister winch 6, secondary hoist rope 9 passes Shears top pulleys group 11 and jib head assembly pulley 13 on secondary suspension hook 15.Shears is connected with turn table top by the hinge that is contained in root with jib, the turn table bottom is connected with pedestal by rotary supporting device, pedestal is directly installed on the platform pile shoe as crane foundation, because shoe is the main stress structure of platform, so complete engine set installation in shoe and need not to change the oad of shoe, does not take the platform deck space fully.
