Abstract
The utility model discloses a top driving device of a drilling platform, which mainly comprises a flying ring (1), a box body (2), a hydraulic motor (3) and a main shaft (4). The top driving device is characterized in that the flying ring (1) is fixed at the upper end of the box body (2); the hydraulic motor (3) is fixed in an inner cavity of the box body (2); two ends of the main shaft (4) are fixed in the box body (2) through bearings; and the upper end of the main shaft (4) is directly connected with an output shaft of the hydraulic motor (3). The top driving device can be used by directly driving the hydraulic motor (3) by an engine and connecting the lower end of the main shaft (4) with a drilling rod (5) through threads. The top driving device has the advantages of simple structure, short brake time, stable and reliable performance and low energy consumption; and in addition, the top driving device is free from extra auxiliary equipment, is simple for control and easy for operation and is widely applied to the field of the top driving devices of the drilling platforms.
Description
Technical field
The utility model relates to a kind of top-drive device of offshore boring island.
Background technology
At petroleum exploration field, top-drive device is the higher drilling rig of automaticity on the offshore boring island, the power source of top-drive device generally adopts slowspeed machine to drive at present, and there is following significant disadvantages in the slowspeed machine driving: 1, control is complicated, because field operation environment is poor, the repair rate height; 2, the brake time long, and unstable, easily produce security incident; 3, high temperature and poor performance at low temperatures, electrical fault rate height when high temperature and low temperature; 4, auxiliary equipment is many, and cost consumption is big, can not satisfy the requirement of the big production of modernized energy-saving and emission-reduction.
Summary of the invention
The purpose of this utility model is developed a kind of addressing the above problem exactly, and is simple in structure, and the brake time is short, dependable performance is stable, and energy consumption is low, does not need extra auxiliary equipment, the top-drive device of the offshore boring island that control is simple and easy to grasp.
The utility model is achieved through the following technical solutions:
The utility model mainly is made up of suspension ring, casing, hydraulic motor and main shaft, it is characterized in that: suspension ring are fixed on the casing upper end, hydraulic motor is fixed in the cabinets cavity, main shaft two ends are by in the bearing fixing casing, the main shaft upper end directly is connected with hydraulic motor output shaft, in use, the main shaft lower end reaches purpose of design by the drilling rod that is threaded.
When installing and using, drilling rod is connected with the main shaft lower end by screw thread, adopts hydraulic motor as main power source, the direct drive shaft of hydraulic motor, and the centre need not any servicing unit, and energy consumption is low, and is stable and reliable for performance, reaches purpose of design.
The utlity model has following advantage:
1, via enforcement of the present utility model, adopt the direct drive shaft drilling well of hydraulic motor, middle no any auxiliary articulating cuts down the consumption of energy greatly.
2, via enforcement of the present utility model, hydraulic motor directly drives good stability, and fault rate is low.
3, via enforcement of the present utility model, simple in structure, easy operating easy to control.
4, via enforcement of the present utility model, there is not extra auxiliary equipment, motor directly drives hydraulic motor, need not generating set, and this is highly beneficial to field work.
5, via enforcement of the present utility model, hydraulic motor directly brakes, and the time is short reliable and stable.
