Abstract

The invention provides a full-automatic clamping hoop used for seabed jacket repairing. The full-automatic clamping hoop comprises a jacket, an upper saddle plate and a lower saddle plate, the upper saddle plate and the lower saddle plate are connected through a revolving shaft, a hydraulic opening-closing mechanism is arranged on one sides of the upper saddle plate and the lower saddle plate, hydraulic locking mechanisms are arranged on two sides of the upper saddle plate and the lower saddle plate, the hydraulic opening-closing mechanism comprises two connected closed hydraulic cylinder reinforcing ribs and closed hydraulic cylinders which are fixedly on the upper saddle plate and the lower saddle plate respectively, and the hydraulic locking mechanism comprises a compression hydraulic cylinder, a connecting rod, a pushing rod, a spring, a locking cam, a compression lever and a side plate. The clamping hoop is integrally moved to the jacket to be repaired through a suspension cable, the hydraulic cylinders control the saddle plates to open, the position of the suspension cable is adjusted to enable the saddle plates to wrap the jacket, and the hydraulic cylinders return to control the saddle plates to close; a locking hydraulic cylinder extends out, a buckle plate is pushed to rotate, and the cam is pushed to enable the lever to compress the side plate; self-locking of the whole clamping hoop is completed by the cam, and repairing work of the jacket is completed.

Description

technical field [0001] The invention relates to a device for repairing a submarine jacket, in particular to a fully automatic clamp for repairing a submarine jacket. Background technique [0002] The clamp is an outsourcing structure made according to the shape of the damaged component. It can be two or more lobes, and the lobes are connected with bolts to form a pipe clamp to clamp the damaged component. Friction or shear bonds between members to transmit force. There are four main types: mechanical clamps, grouting clamps, pressure grouting clamps, and resin clamps. Clamp technology can be used to repair or strengthen one or more connected pipe fittings. The pre-tightening and locking methods of the clamps mostly adopt the bolt connection method, and the automatic operation has not been realized yet. Contents of the invention [0003] The purpose of the present invention is to provide a fully automatic clamp for subsea jacket repair that can realize fully automatic un...
