Abstract

The invention discloses a clamping device for an ore conveying pipe laying work in deep-sea mining. The clamping device comprises two valve sliding blocks. Each valve sliding block is provided with a spherical hinge support, a spherical hinge composed of two hemispheres, a hydraulic oil cylinder for opening and closing the corresponding valve sliding block in a drive manner, a mounting base, a valve base and a hydraulic type heave compensation device. The hydraulic oil cylinders, the mounting bases of the hydraulic oil cylinders, the valve sliding blocks, the spherical hinge supports and the spherical hinges are symmetrically arranged on the valve bases. The lower portions of the valve bases are connected with the hydraulic type heave compensation devices. Bases of the hydraulic type heave compensation devices sit on a working platform of a mother ship on the water surface. The clamping device has the functions of laying and recycling hard metal pipes and hoses for deep-sea mining and other engineering and can solve the bending moment and inertial force problems generated when pipes bear various resultant force at a certain ocean depth in the working process, and it can be guaranteed that the pipes work safely and reliably.

Description

technical field [0001] The invention relates to the technical field of deep-sea mining engineering, in particular to a clamping device used for the laying operation of ore conveying pipelines in deep-sea mining. Background technique [0002] Due to the characteristics of the marine environment, deep-sea mining is affected by tidal currents, wind waves, and inertial forces. In particular, the technology of placing the submarine ore transportation pipeline with a length of several kilometers on the surface working mother ship and ensuring the safe and reliable operation of the pipeline has gained international and domestic attention. Still a problem. During the "Ninth Five-Year Plan" period, my country completed the pilot test technology design of the deep sea mining system and the 150-meter water depth lake test of some mining systems, and accumulated certain experience. However, at present, there are few domestic studies on the deployment and recovery of pipelines from the ...
