Technical field
The utility model relates to a kind of equipment On The Offshore Platform, particularly a kind of ball screw type drilling platform lifting mechanism.
Background technology
Along with the in-depth that the mankind utilize petrol resources exploitation, oil-gas exploration and development proceeds to ocean from land.Therefore, drilling engineering operation also must be carried out in the vast oceans.While carrying out oil/gas drilling construction at sea, the rig that hundreds of ton is heavy will have the space of enough support and placement, also will have drilling implementer to live simultaneously and occupy residence, and offshore drilling platforms has just been shouldered this important task.Due to changeable, the marine stormy waves of sea climate and the destruction of bathycurrent, stability and the safety of offshore drilling unit become more important.
The modal pinion and-rack of platform lifting device and jacking hydraulic cylinder type.Pinion and-rack can be realized continuous lifting, and speed is fast, flexible operation, but needs complexity and huge reducing gear, volume is very large, after platform hoists, is fixed with brake, and elevating mechanism is always in stress, to having relatively high expectations of rack-and-pinion, security performance is lower.Hydraulic pressure lifting mechanism does not need complicated gear, and volume is little, and transmission efficiency is high, and control ratio is more flexible, but lifting continuously, speed is slower, troublesome poeration, hydraulic oil and hydraulic valve piece are had relatively high expectations, and hydraulic test security performance is lower, also high to technician's requirement.
Utility model content
The purpose of this utility model is exactly for present situation, and a kind of ball screw type drilling platform lifting mechanism is provided, and the complexity that overcomes current drilling platform lifting mechanism is huge, lifting is unstable, and volume is excessive, and process is discontinuous, the shortcomings such as safety factor is low, its technical scheme adopting is as follows:
Ball screw type drilling platform lifting mechanism, it is characterized in that: comprise platform base, driving chain, pinion, spud leg, feed screw nut, screw, driven sprocket, drive sprocket, spud leg bearing, drive bevel gear, motor, power transmission shaft, driven wheel of differential, shaft coupling, described spud leg lower end is plugged in platform base, between be provided with spud leg bearing, ensure the stable rotation of described spud leg, on spud leg, there is equally distributed screw thread everywhere to coordinate with feed screw nut, be provided with ball between the two, feed screw nut is cemented in the hole that platform opens by screw, driven sprocket is fastened on spud leg lower end by key and is not provided with screw thread place, driving chain and four driven sprocket synchro-meshing transmissions, ensure that four driven sprocket speed are consistent.
Above-mentioned ball screw type drilling platform lifting mechanism, it is characterized in that: transmission system mainly comprises motor, shaft coupling, drive bevel gear, driven wheel of differential, power transmission shaft, drive sprocket, driven sprocket, the moment of torsion of motor is passed to drive bevel gear by described shaft coupling, drive bevel gear be arranged on the driven wheel of differential engaged transmission on power transmission shaft, drive sprocket is connected and is fixed on power transmission shaft by key, drive sprocket and driven sprocket engaged transmission.
The utlity model has following advantage: adopt ball-screw-transmission can greatly improve gearratio, reduced the volume of transmission system, simple in structure; Utilize chain drive and Bevel Gear Transmission, four driven sprocket Synchronous Transmission, lifting platform process is steadily reliable; Machine driving control system is simple, has saved the cost of control system.
