Block 50 connects, and the position between two fixed support block 50 of corresponding arbitrary neighborhood is at least provided with a postive stop baffle 52,
When retractable support block 60 stretches out upper backup pad 20 and lower supporting plate 30, postive stop baffle 52 keeps off the side stretched out at retractable support block 60
Upwards, prop up retractable support block 60, thus avoid retractable support block 60 to stretch out further.
Preferably, fixed support block 50 is provided with the multiple slots 53 for installing postive stop baffle 52, multiple slots 53
Direction along retractable support block 60 activity is spaced, such that it is able to postive stop baffle 52 is plugged in the slot 53 of diverse location
In, to change the extended upper backup pad of retractable support block 60 20 and the greatest length of lower supporting plate 30, thus regulate shoe
Large volume, to adapt to the needs of different operating environment.
In the present embodiment, multiple postive stop baffles 52 are connected to multiple fixed support block 50 side away from support column 40,
So that the length that retractable support block 60 can stretch out upper backup pad 20 and lower supporting plate 30 is maximum.
Fig. 6 is the structural representation of a kind of retractable support block that the embodiment of the present invention provides, and Fig. 7 is the C-C cross section in Fig. 6
Figure, in conjunction with Fig. 6 and Fig. 7, multiple retractable support blocks 60 is provided with mounting groove 61, mounting groove 61 in the one side inside shoe
Inside it is provided with telescopic oil cylinder and connects seat 62, retractable support block 60 and flexible oil can be facilitated by arranging telescopic oil cylinder connection seat 62
The connection of cylinder 70.
Specifically, telescopic oil cylinder connects seat 62 with telescopic oil cylinder 70 by being plugged in the cylinder that telescopic oil cylinder is connected on seat 62
Sell hinged so that can rotate in little scope between telescopic oil cylinder connection seat 62 and telescopic oil cylinder 70, such that it is able to flexible
When the prolonging direction of oil cylinder 70 not exclusively overlaps with the glide direction of retractable support block 60, it is to avoid retractable support block 60 is stuck and nothing
Method activity.
Seeing Fig. 3, support column 40 is provided with multiple telescopic oil cylinder mounting seat 41, multiple telescopic oil cylinders 70 are stretched by multiple
Contracting cylinder installation seat 41 is connected with support column 40, and telescopic oil cylinder mounting seat 41 can also be flexible by being plugged in telescopic oil cylinder 70
Straight pin on cylinder installation seat 41 is hinged.
Fig. 8 is the top view of a kind of upper backup pad that the embodiment of the present invention provides, and as shown in Figure 8, upper backup pad 20 sets
Being equipped with multiple fourth hole 22, multiple fourth holes 22 are arranged on the corresponding position within spud leg 10 of upper backup pad 20, flexible oil
The oil circuit control of cylinder 70 can extend on ocean platform by multiple fourth holes 22 and spud leg 10 are internal, in order to flexible
Oil cylinder 70 is controlled.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
