The specific embodiment
Below in conjunction with the drawings and specific embodiments technical solutions of the utility model being described in detail, further understanding the purpose of this utility model, scheme and effect, but is not the restriction as the utility model claims protection domain.
Consult Fig. 1 and Fig. 2, Fig. 1 is the three-dimensional structure diagram that spud leg segmental hoisting of the present utility model protects cable device, and Fig. 2 protects the exploded view of cable device for spud leg segmental hoisting of the present utility model.Spud leg segmental hoisting of the present utility model protects cable device 100 can protect the structure of main chord tube 200 when lifting main chord tube 200, and can reduce the wearing and tearing to the lifting hawser.
Spud leg segmental hoisting of the present utility model protects cable device 100 and comprises attaching parts 110 and semicolumn casing 120, and wherein, attaching parts 110 is at least one, and semicolumn casing 120 is two.Each semicolumn casing 120 comprises that an arcuate member 121 and two end parts, 122, two end parts 122 are connected to the two ends of arcuate member 121.Two end parts 122 can be connected the two ends of arcuate member 121 in the mode of welding.
Preferably, the right angle part of the groove 123 of end part 122 has fillet 124, and the radius of fillet 124 is more than the 15mm radius, to prevent from destroying the structure of main shipboard tube 200 in the process of lifting spud leg segmentation 210.
Further, the steel plate thickness book of the comparable end of the steel plate thickness part 122 of arcuate member 121 is to alleviate the overall weight that the spud leg segmental hoisting protects cable device 100.
