Abstract
The utility model relates to a cylindrical pile leg for self-elevating platform, mainly solving the problems that a local structure bearing manner of the prior cylindrical pile leg is irrational, and the stress at technological hole is concentrated. Longitudinal reinforced ribs (4) are arranged at a position, corresponding to a rack, at inner side of a pile leg cylinder wall (1), a plurality of supporting plates (5) are arranged between two reinforced ribs (4), and a reinforced toggle plate (6) is connected between the reinforced rib (4) and the supporting plate (5); a reinforcement plate (7) is arranged between a pipeline joint (8) and the pile leg cylinder wall (1). The cylindrical pile leg for self-elevating platform has the advantages of high anti-fatigue ability; the reinforced plate is adopted at the technological hole so that the concentrated stress is avoided.
Description
Technical field:
The utility model belongs to field of ocean engineering, the cylindrical spud leg that a kind of specifically marine jack-up unit is used.
Background technology:
Existing at home and abroad many jack-up units, the shape of spud leg generally is divided into cylindrical and truss-like, and for the cylindrical spud leg of the many employings of 50 meters following depth of waters.Existing cylindrical spud leg is because inner the reinforcement only adopted vertical purlin of meridosternous and ring beam, and ring beam is very intensive, and adopts the meridosternous purlin stressed unreasonable with two web purlins structure compared; Simultaneously, spud leg is opened the fabrication hole place and is not done the reinforcement processing, makes the fabrication hole place easily cause stress to concentrate, and has potential safety hazard.
The utility model content:
The problem unreasonable for the partial structurtes force way that overcomes existing cylindrical spud leg, that fabrication hole place stress is concentrated, the utility model provides a kind of jack-up unit used cylindrical spud leg, and this cylindrical spud leg has the anti-fatigue ability height, the fabrication hole place adopts stiffener and avoided the concentrated characteristics of stress.
The technical solution of the utility model is: the cylindrical spud leg that a kind of jack-up unit is used, comprise spud leg barrel plate, ring beam, pipe joint, there is waling the position of the inboard corresponding tooth bar of described spud leg barrel plate, between two reinforcing ribs several gripper shoes are arranged laterally, and have deep bracket to be connected between reinforcing rib and the gripper shoe; Between described pipe joint and the spud leg barrel plate stiffening plate is arranged.
The utlity model has following beneficial effect: owing to take such scheme, there is waling spud leg barrel plate inboard, and gripper shoe is arranged between the reinforcing rib, like this, under the concentrated force effect of lifter wheel, can keep the local strength and the rigidity of spud leg, improve the anti-fatigue ability of pile leg structure; Between the pipe joint of fabrication hole and the spud leg barrel plate stiffening plate is arranged, then avoided stress to concentrate, strengthened the intensity at fabrication hole place.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the sectional views along A-A in the accompanying drawing 1;
Accompanying drawing 3 is the sectional views at fabrication hole of the present utility model place.
1-spud leg barrel plate among the figure, 2-ring beam, 3-tooth bar, 4-reinforcing rib, 5-gripper shoe, 6-deep bracket, 7-stiffening plate, 8-pipe joint.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2, shown in Figure 3, the cylindrical spud leg that a kind of jack-up unit is used, comprise spud leg barrel plate 1, several ring beams 2 are arranged in the spud leg barrel plate 1, there is waling 4 position of described spud leg barrel plate 1 inboard corresponding tooth bar 3, several gripper shoes 5 are laterally arranged between two reinforcing ribs 4, gripper shoe 5 is square or pipe, and there is deep bracket 6 to be connected between reinforcing rib 4 and the gripper shoe 5, like this, under the concentrated force effect of lifter wheel, can keep the local strength and the rigidity of spud leg, improve the integrally-built anti-fatigue ability of spud leg.Because platform has functions such as the stake of dashing, draining, need on spud leg barrel plate, fabrication hole be set, local strength's influence for spud leg is bigger like this, and easily cause stress to concentrate, need reasonable Arrangement and reinforcement, avoid influencing each other, adjacent two perforates be not less than 1m to spacing in length and breadth, between the pipe joint 8 at fabrication hole place and the spud leg barrel plate 1 stiffening plate 7 is arranged, stiffening plate 7 materials are identical with spud leg barrel plate 1 material, and its sectional dimension is not less than perforated area, and cut tiltedly excessively evenly at the position, edge, avoid stress to concentrate, strengthened the intensity at fabrication hole place.
Claims (1)
1. cylindrical spud leg that jack-up unit is used, comprise spud leg barrel plate (1), ring beam (2), pipe joint (8), it is characterized in that: there is waling (4) position of the inboard corresponding tooth bar of described spud leg barrel plate (1) (3), several gripper shoes (5) are laterally arranged between two reinforcing ribs (4), and have deep bracket (6) to be connected between reinforcing rib (4) and the gripper shoe (5); Between described pipe joint (8) and the spud leg barrel plate (1) stiffening plate (7) is arranged.
