Embodiment 1

[0019] Such as figure 1 , 2 , 3, the anchoring device is composed of guide rail support beam 1, fixed seat 2, anchor seat 3, nut 4, lock nut 5, handle 6, anchor pin shaft 7, crane driving beam 8, etc. The upper part of the anchor pin shaft 7 is threaded and the lower part is a smooth shaft. Rotate the anchor pin shaft 7 through the handle 6 to move up and down on the anchor seat 3, so that the anchor pin shaft inserts or leaves the fixed seat 2, and tightens the lock nut 5 to make the anchor pin shaft 7 move up and down. The fixed pin shaft 7 will not move even in a vibrating state, and the entire crane is fixed at a designated position through a total of 4 anchoring devices, and no slippage, overturning and other movements will occur.

[0020] The specific operation process:

[0021] Before the crane is ready for work, it must be ensured that the anchor pin shaft 7 of each anchor device is completely disengaged from the anchor seat. The specific operation is to first loose...

Abstract

The invention relates to an anchoring device of a crane for a water insulation pipe crane capable of meeting a deepwater floating-type ocean drilling platform and a drilling ship, and belongs to the technical field of deepwater ocean petroleum drilling. The anchoring device provided by the invention comprises an anchoring seat, an anchoring pin shaft, a nut, a locking nut, a handle and a fixed seat; the nut is welded on the anchoring seat; the anchoring seat is welded on a driving beam of the crane; the anchoring pin shaft is screwed on the nut and the anchoring seat through threads; the fixed seat is welded on a designated part of a crane guide rail support beam; the upper end part of the anchoring pin shaft is provided with the handle; the locking nut is screwed on the anchoring pin shaft. The invention provides the anchoring device which is simple in structure and is wide in application, so that the crane can keep the stable state under the motion states of lifting, sinking, vibration and the like of a drilling platform (ship), cannot generate damage motions of slippage, toppling and the like, and is low in maintaining expense.

Description

technical field [0001] The invention relates to an anchoring device, in particular to an anchoring device for a riser crane used on an ocean drilling platform and a drilling ship, and belongs to the technical field of deep-water offshore oil drilling. Background technique [0002] Drilling riser crane is one of the important links in the whole deepwater offshore oil drilling equipment, because the floating drilling platform and drilling ship will have heave, swing, sle An anchoring device is required to fix it during work to prevent it from slipping and overturning. [0003] At present, the common anchoring methods are fixed by the pin driven by the hydraulic cylinder and locked by the turnbuckle. The hydraulic control system is added to the hydraulic cylinder fixing method, which brings certain difficulties to maintenance. The turnbuckle locking method is difficult to arrange in some structures and cannot be realized. It can only be used in some special design structures. ...
