Description
Technical Field
The utility model relates to a dig rig elevator soon belongs to and digs rig technical field soon.
Background
The existing rotary drilling rig elevator is characterized in that an upper joint is connected with a steel wire rope, a lower joint is connected with a drill rod, the steel wire rope, the elevator and the drill rod are in a straight line during normal operation, and the upper joint and the lower joint of the elevator can rotate relatively. The elevator has the first function of transferring the lifting force of the steel wire rope and lifting or lowering the drill rod; the second function is to isolate rotation, i.e. to ensure that the steel wire rope does not follow rotation when the drill rod works, thereby protecting and prolonging the service life of the steel wire rope. In order to realize the normal work of the elevator, the vertical state between the elevator and the drill rod connecting plate is kept when the rotary drilling rig drills; if the elevator leans against the inner wall of the outer section of the drill rod obliquely relative to the drill rod connecting plate, the upper joint and the lower joint of the elevator rotate together along with the drill rod, the isolation rotation function fails, the drill rod can drive the steel wire rope to rotate together during the drilling work of the rotary drilling rig, the steel wire rope is forced or broken, and the steel wire rope is easy to damage.
However, at present, the lowering length of the steel wire rope is not controlled accurately in the construction process, and the lowering length of the steel wire rope is often longer than the actually required lowering length due to the operation of a manipulator, so that the main coil is called as over-lowering in the industry. When the condition occurs, the steel wire rope cannot provide upward pulling force for the elevator, and the elevator rotates and inclines around a pin shaft of the lower joint and the drill rod connecting plate to lean against the inner wall of the outer section of drill rod under the action of factors such as vibration, gravity and the like; at the moment, the upper joint and the lower joint of the elevator rotate along with the drill rod, and the function of isolating rotation is invalid. When the isolation function is seriously failed, the phenomena of coiling, breaking, kinking and the like of the steel wire rope can be caused, and the steel wire rope is directly damaged; when the drill rod is slightly lifted, the elevator rotates at a high speed under the action of the torque transmitted by the steel wire rope, and the service life of the elevator and the steel wire rope is seriously influenced.
Disclosure of Invention
