It is interior, first clamping plate 11 and second clamping plate 12 are arranged in the left and right sides of shearing-resistance blocks 10, and make the first wedge 15a and the second wedge
Shape block 15b correspondences are arranged in the first groove 11a, by the position relationship for adjusting the first inclined-plane 110a and the second inclined-plane so that
First clamping plate 11 can be pressed on the first wedge 15, install the second locking member 14, and be arranged in the first wedge 15 correspondence
In second groove 12a, by the position relationship for adjusting the 3rd inclined-plane 120a and the 4th inclined-plane so that second clamping plate 12 can be pressed in
On second wedge 16, eventually through locking the second locking member 14 make the second semifocal chord pipe 5, first clamping plate 11, second clamping plate 12 with
4th semifocal chord pipe 8 clamps the second rack 6 by the second locking member 14, and the first spud leg unit 1 is lifted in place, makes the cloth of shearing-resistance blocks 10
Be placed in the first breach 3a, install the first locking member 13 simultaneously screw the first locking member 13, make the first semifocal chord pipe 4, first clamping plate 11,
Second clamping plate 12, the 3rd semifocal chord pipe 7 clamp the first rack 3 respectively by the first locking member 13, while further screwing the first lock
The tight locking member 14 of part 13 and second, makes the first locking member 13 and the second locking member 14 locked, so that first clamping plate 11 and second
Clamping plate 12 fits the first rack 3 and the second rack 6 is arranged, and then detachable spud leg is had by connection unit 9
Good stress-bearing capability, when detachable spud leg includes two or more spud leg unit, is carried out according to above-mentioned installation process
Installation.
The embodiments of the invention provide a kind of detachable spud leg, lacked by offering first on the end face of the first rack
Mouthful, the second breach is offered on the end face of the second rack, shearing-resistance blocks is installed in the first breach and the second breach, shearing-resistance blocks energy
The shearing that the first spud leg unit and the second spud leg unit are present enough is effective against, first clamping plate and second clamping plate pass through first respectively
Wedge and the second wedge clamp shearing-resistance blocks so that the first spud leg unit and the second spud leg unit are us shown firmly attached to one
Rise, so that the stress-bearing capability of detachable spud leg is ensure that, meanwhile, set oblique at the top of the first wedge and the 3rd wedge
Face, so ensure that can bear larger pulling force during detachable spud leg pile pulling, and also ensure that first is recessed
Groove and the first wedge are in close contact, and the second groove and the second wedge are in close contact, so as to ensure that self-elevating ocean platform
Security, expand the application of rack-and-pinion elevating mechanism.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
