Cable-type cracked component replacement device with tensioning fixture

Abstract

The invention provides a cable-type cracked component replacement device with a tension clamp. The present invention comprises a main casing and a rope retraction mechanism arranged therein, the first rope outlet and the second rope outlet for rope retraction are provided in the length direction of the main casing, and the rope retraction mechanism includes the main casing The rotating shaft set at the center of the body axis is driven by the external winch to rotate, so that the rope protrudes from the rope outlet, the two sides of the crack to be connected are respectively fixed with fixing parts, the first rope outlet and the second rope outlet lead out The ropes are respectively connected with the fixing pieces on the corresponding sides. The rope is used instead of the original component to play a stretching role. The boundary of the rope is closely connected with the stable part around the crack, and then the rope is tightened to form a whole with the structure around the crack, replacing the original continuous structure to play a stretching role. The invention does not destroy the original structure, and shares the tension of the original components, thus greatly improving the safety of the components here.

Description

technical field [0001] The invention relates to the technical field of ship safety, in particular to a cable-type cracked component replacement device with a tensioning fixture. Background technique [0002] Since ships and offshore platforms are often subjected to other effects such as wave loads, cracks are prone to occur in components, which will have a certain impact on the safety of ships or offshore platforms. When a crack occurs on a platform or a ship, if it is inconvenient to repair immediately or return to the ship for repair, the leak can be plugged at the position of the crack by a leak stopper, such as "A Curtain Type Ship Crack Stopper" with the announcement number CN107284617A and leak plugging method”, as well as technologies such as stretch-rolled ship leak plugging blanket and fast leak plugging umbrella. However, these methods do not effectively prevent the further expansion of cracks, and do not share the tensile force for the cracked components to preve...

Problems solved by technology

For example, the announcement number is CN 110524961A's "A Kind of Crack Repair Stretch-resistant and Anti-crack Cloth and Its Manufacturing Method", CN 111155424 A's "A Kind of Concrete Bridge Deck Assembled Expansion Device and Its Manufacturing", CN208466391U's "A Kind of Steel Crack Cutting Device", but the current existing technology further prevents the expansion of cracks by wrapping anti-crack cloth at the cracks of components or through some methods of reinforcement and digging holes. The situation under the action of external force will not apply

Many components of ships and offshore platforms have been immersed in water for a long time, so the method of winding anti-crack cloth will affect the viscosity of crack cloth, and the method of digging holes to prevent crack propagation will affect the strength of components, due to the long-term effect of wave load , may accelerate the fatigue damage of components
