Structure schematic diagram.Marine drilling platform shown in Fig. 1 includes platform body 01, multiple lifting gears 02 and multiple spud legs 03.Wherein,
Each spud leg 03 is both secured to seabed 05, and each spud leg 03 coordinates with lifting gear 02 correspondingly.Platform body
01 lifting gear 02 by being fixed thereon is connected with multiple spud legs 03, multiple lifting gears 02 drive platform bodies 01 along
Multiple spud legs 03 move and then realize the lifting of platform body 01.By taking oil exploitation as an example, when marine drilling platform completes drilling well
Need platform body 01 dropping to the water surface 04 after work, as shown in Figure 1.
Please refer to Fig.2, lifting gear 02 generally includes the multiple motor being distributed in groups, and the output terminal of motor is gear
021, and spud leg 03 has rack 031, motor output end forms rack and pinion mechanism with spud leg 03.Since motor is fixed on
Platform body 01, therefore by the gear and the engaged transmission of spud leg 03 of its output terminal, can finally realize platform body 01 along spud leg
03 elevating movement.
During platform body 01 is risen or fallen, lifting gear 02 drives platform body 01 to move, and works as liter
