Description
Technical field
This utility model belongs to technical field of fixed buildings, especially relates to the improvement of a kind of self-elevating drilling platform structure.
Background technology
In recent years, along with growing continuously and fast of World Economics, crude resources consumption demand amount be will be further increased by the whole world.Being gradually decreased by land resources, be on the verge of threatening of exhaustion, a lot of countries start sight is turned to ocean in the world, are obtained the marine resources such as oil by drilling technology, have thus promoted the development of drilling platforms.
Self-elevating drilling platform, is also called footing formula drilling platforms, is the most commonly used drilling platforms of current domestic and international application.Self-elevating drilling platform can be divided into three parts；Hull, shoe and elevating mechanism.When needing well-digging, being inserted by spud leg or be seated in seabed, hull also can swash along spud leg, leaves sea, can not be affected by seawater movement during work.After beating completion, hull can climb down along spud leg, floats across the sea, then footing is extracted seabed, and rise certain altitude, gets final product towage to new well location.
Self-elevating drilling platform exposes a lot of problem in use；Such as, one, spud leg is fragile；When two, carrying out lifting platform due at each spud leg progress different, single walking strength of gear is excessive, the problem that walking gear damages easily occurs.Platform safety and service life are affected the biggest by these problems, it is necessary to solve in time.
Summary of the invention
This utility model is aiming at the problems referred to above, it is provided that a kind of be hardly damaged and safe and reliable self-elevating drilling platform.
For realizing above-mentioned purpose of the present utility model, this utility model adopts the following technical scheme that, a kind of self-elevating drilling platform, including platform body, it is characterized in that: uniform three spud legs on platform body, described spud leg includes three chord members, arranges in equilateral triangle shape between three chord members；Being placed with several connection unit between three chord members the most successively, described connection unit is included in connecting rod arranged in a crossed manner between adjacent chord member, is respectively connected with fixing bar between the connecting rod cross point on three faces of spud leg；Being provided with lifting structure between platform body and spud leg, described lifting structure includes the motor being arranged on platform body, and the output shaft of motor is provided with walking gear, is provided with walking rack with being meshed with walking gear on the chord member of spud leg；Be provided with position limiting structure on platform body accordingly with walking gear, described position limiting structure includes that the spacing tooth bar of walking gear side, spacing tooth bar are connected with driving structure；Platform body is evenly equipped with three tank gages, is connected by linker between described three tank gages, the signal output part connection control system of tank gage.
As a kind of preferred version, described driving structure is cylinder or oil cylinder.
As a kind of preferred version, described control system is made up of PLC module, communication module, display module and alarm；Liquid level signal is sent to PLC module by tank gage, and PLC module is delivered to display module by communication module after processing tank gage fed-back current signals and carries out the display of three liquid level signals.Between three liquid levels, difference is reported to the police when exceeding predetermined value；Operator adjust lifting structure speed on three spud legs in time.Make that lifting platform is more stable, safety.
As another kind of preferred version, it is provided with the hutch water device communicated with linker in linker one end.
The beneficial effects of the utility model.
This utility model spud leg is made up of three chord member arrangements triangular in shape, and arranges connection unit between three chord members；Stabilized structure, it is hardly damaged.It addition, be evenly equipped with three tank gages connected by linker on platform body；It is the most stable that the liquid level signal exported by tank gage judges that platform rises.Avoid platform inclination and rise the problem causing walking gear deformed damaged.
