A cantilever beam moving and locking device

Abstract

The invention relates to a moving and locking device for a cantilever beam, and belongs to the field of marine work platform auxiliary devices. The moving and locking device comprises a cantilever beam moving mechanism and a cantilever beam locking mechanism, and the cantilever beam moving mechanism is composed of one set of single bodies or formed by arraying multiple sets of single bodies at intervals in sequence; each set of single bodies comprises a supporting frame, a lifting mechanism arranged inside the supporting frame and a driving mechanism which is matched with the lifting mechanism in a driving mode; the locking mechanism comprises a locking block matched with the bottom surface of the cantilever beam in a locking mode, and is arranged on one side of each supporting frame. Moving and locking of the cantilever beam are combined in an integrated mode, by the adoption of a pin roller structure, force needed by movement can be greatly reduced, and meanwhile damage and blocking are avoided; by the adoption of a locking wheel locking mode, the weight of the facility to be moved is fully utilized, and the facility can be reliably locked at any position in a mechanical mode; the device has the advantages of being compact in structure, large in moving ability, reliable in locking, small in occupied space, good in economy and the like.

Description

technical field [0001] The invention relates to a cantilever beam moving and locking device in the field of auxiliary devices for offshore operation platforms, which is applied to the cantilever beam moving and locking at any position. Background technique [0002] The offshore platform is the infrastructure for the exploration and development of offshore oil and gas resources. Each shift requires the cooperation of multiple ships, and the cost is high. Therefore, in general, multiple wells can be drilled or repaired at one time. Shifting; usually the cantilever beam moves more than 20 meters, and its own weight is more than 1,000 tons when moving. The variable load that needs to be added during the cantilever beam operation is also hundreds of tons or even thousands of tons. It needs to be locked after the position. Therefore, a large pushing force is required when moving. Metal adhesion or damage often occurs at the sliding joint, and even cannot be moved. It is difficult ...

[0002] The offshore platform is the infrastructure for the exploration and development of offshore oil and gas resources. Each shift requires the cooperation of multiple ships, and the cost is high. Therefore, in general, multiple wells can be drilled or repaired at one time. Shifting; usually the cantilever beam moves more than 20 meters, and its own weight is more than 1,000 tons when moving. The variable load that needs to be added during the cantilever beam operation is also hundreds of tons or even thousands of tons. It needs to be locked after the position. Therefore, a large pushing force is required when moving. Metal adhesion or damage often occurs at the sliding joint, and even cannot be moved. It is difficult to effectively and reliably lock during operation, which not only affects the operation but also exists Security risks
