Technical field
The present invention relates to marine drilling platform equipment technical field, specifically a kind of self-elevating drilling platform rig floor is anti-
The locking device for sliding and toppling.
Background technology
Self-elevating drilling platform is the important equipment of offshore oil exploration and development, relative to the cantilever beam of traditional form, is bored
Platform and cantilever beam are split type.To meet platform in same place erect-position, the demand of more mouthfuls of oil wells is drilled, jack-up rigs are flat
The rig floor needs of platform can do transverse horizontal movement on a cantilever beam.During actual well drilled operation and towage, by operating area
Wind-force, rig floor shake and the influence of the factors such as platform pitching, rolling, and rig floor will appear sliding or be inclined in track supporting beam
Phenomenon is covered, and then leads to serious accident.Therefore jack up rig floor needs to carry out it in drillng operation and platform towage
Fixed locking.The modes such as rig floor locking mode generally use voussoir friction lock or bolt locking.Voussoir locking mode rig floor
Locking, relieving flow chart are cumbersome, and the activity duration is long, and labor intensity is big, and poor reliability；Bolt locking mode is only capable of
It is locked under depositing operating mode in fixed position in towage or storm, and when rig floor is in normal operation, it cannot achieve in office
Anticipate position locking, once operating area wind speed increase or platform wave inclination angle it is excessive when, rig floor may be caused to slide, safety
Poor performance.
Invention content
The object of the present invention is to provide a kind of self-elevating drilling platform rig floor antiskid and the locking devices to topple, to solve

Liang Shang；When rig floor is shifted, operating personnel is by reversely rotating positive left-hand thread adjusting nut, the drawing locking of derotation leading screw
Pawl top is rotated around rotary pin shaft, and locking pin is detached from locking pin hole, and rig floor releases locking state.
When rig floor slide device moving displacement is the integral multiple of stepping stroke, the locking pin on locking jaw and locking pin hole
It can smoothly coordinate, realize the locking of rig floor；When rig floor slide device moving displacement is not the integral multiple of stepping stroke, adjust
The adjusting nut at rotary pin shaft both ends finely tunes the position of locking jaw, keeps locking pin opposite with locking pin hole just, realizes the lock of rig floor
Tightly.
Beneficial effects of the present invention are：
（1）The present invention in rig floor rest base both sides by being arranged locking jaw, the locking pin on locking jaw and cantilever beam rail
Locking pin hole in road supporting beam stiffener plate is interlocked or is detached from, and resistance is provided by the cooperation of locking pin and locking pin hole
The active force for sliding and toppling makes rig floor be locked at any position of cantilever beam orbit supporting beam during normal operation, keeps away
Exempt from rig floor sliding occurs or topples, locking/unlock simple operation is time saving and energy saving, and unfailing performance is high；
（2）When rig floor is slid onto certain position, locking pin and locking pin hole decentraction when can not fasten, pass through adjusting
Adjusting nut in rotary pin shaft both sides is set, it can be achieved that locking jaw fine position, makes locking pin be interlocked with locking pin hole, in fact
The locking of existing rig floor；
（3）Forward and reverse adjusting screw is arranged in the top of locking jaw in the present invention, can easily manipulate locking jaw around rotation
Shaft rotation of shipping and reselling on another market is dynamic, realizes locking pin on locking jaw and the fastening of locking pin hole or detaches.
