Technical field
The utility model belongs to petroleum machinery manufacturing technology field, relates to a kind of hoisting system of rig of low-speed high-thrust linear motor driving.
Background technology
At present; The oil-well rig Hoisting System mainly is power with the electric rotating machine; The transmission mechanism that utilizes parts such as reduction box, cylinder to form rotatablely moves motor and is converted into rectilinear motion, and through wire rope, assembly pulley hoisting hook, top drive, instrument such as drilling rod carries out drillng operation; The output characteristics of electric rotating machine is determining to adopt mechanisms such as cylinder that this is rotatablely moved and is converting rectilinear motion into, so caused the huge and complicated of drive line, has influenced the efficient of system.Linear electric motors are a kind of electric energy to be directly changed into rectilinear motion mechanical energy and without any need for the transmission device of intermediate conversion mechanism, owing to adopt " zero transmission ", more conventional traditional kind of drive has a clear superiority in.
Summary of the invention
The purpose of the utility model provides a kind of hoisting system of rig of low-speed high-thrust linear motor driving; Having solved in the prior art with the electric rotating machine is power; Must adopt mechanisms such as cylinder that this is rotatablely moved and convert rectilinear motion into; There is the huge and complicated of drive line, the inefficient problem of system.
The technical scheme that the utility model adopted is that a kind of hoisting system of rig of low-speed high-thrust linear motor driving vertically is installed with linear motor stator electric in derrick inside, outside linear motor stator electric, is set with linear motor rotor; On the linear motor stator electric top the anti-spacing lever of pounding is installed, this prevents that pounding spacing lever is fixedly connected with derrick; The spacing lever of anti-collision is installed in the linear motor stator electric lower end, and the spacing lever of this anti-collision is fixedly connected with derrick; The linear motor rotor top is fixedly connected with steel cord ends, and wire rope is connected with BHA through angle pulley switching-over back.
The beneficial effect of the utility model is through adopting the low-speed high-thrust linear electric motors as power, to utilize the rectilinear motion characteristic of linear electric motors; Cancel transmission mechanisms such as conventional reduction box, cylinder, reduce driving-chain, improve the efficient of Hoisting System; Promote the drilling tool load through angle pulley; The basic realization " zero transmission ", more conventional Hoisting System volume is little, in light weight, simple in structure, parts are few, efficient is high, satisfies the lifting requirement of rig.
Description of drawings
Fig. 1 is the structural representation of the utility model device.
Among the figure, 1. linear motor rotor, 2. linear motor stator electric, 3. derrick, 4. anti-spacing lever, 5. angle pulley, 6. wire rope, 7. BHA, the 8. spacing lever of anti-collision pounded.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
With reference to Fig. 1, the structure of the utility model device is, vertically is installed with linear motor stator electric 2 in derrick 3 inside, outside linear motor stator electric 2, is set with linear motor rotor 1; On linear motor stator electric 2 tops the anti-spacing lever 4 of pounding is installed, this prevents that pounding spacing lever 4 is fixedly connected with derrick 3; The spacing lever 8 of anti-collision is installed in linear motor stator electric 2 lower ends, and the spacing lever 8 of this anti-collision is fixedly connected with derrick 3; Linear motor rotor 1 top is fixedly connected with wire rope 6 ends, and wire rope 6 is connected with BHA 7 through angle pulley 5 switching-over backs, this BHA 7 comprise push up drive, drilling rod etc.; Angle pulley 5 is fixedly installed in derrick 3 tops on one side.
The operating principle of the utility model device is: the stationary part of linear electric motors is fixedly mounted on the derrick; Mover part upper end is fixedly connected with wire rope; And the angle pulley that passes through crown connects BHA; Prolong the rectilinear motion up and down of stator through linear motor rotor, thereby reach hoisting and lowering function of drilling tool, realize drillng operation.
The course of work of the utility model device is: linear motor rotor 1 moves up and down in linear motor stator electric 2 outsides that are fixedly installed in derrick 3 inside; The wire rope 6 that is hung with BHA 7 is connected with linear motor rotor 1 top through after the switching-over of angle pulley 5; Drag hoisting and transferring of BHA 7 through moving up and down of linear motor rotor 1; When linear motor rotor 1 rises to linear motor stator electric 2 top limit position; The anti-4 pairs of linear motor rotors 1 of spacing lever of pounding are protected spacingly, prevent that BHA 7 from pounding the rig floor face; When linear motor rotor 1 dropped to linear motor stator electric 2 bottom limit positions, 8 pairs of linear motor rotors 1 of the spacing lever of anti-collision were protected spacing, prevented that BHA 7 from running into the derrick superstructure.
The utility model device utilizes the rectilinear motion characteristic of linear electric motors, cancels transmission mechanisms such as conventional reduction box, cylinder, reduces driving-chain, improves the efficient of Hoisting System, and can reduce the volume and weight of Hoisting System, and is simple in structure.
