Embodiment Construction

[0019] to combine Figure 1 to Figure 8 As shown, a deep-sea mining transportation hard pipe clamping and swinging device, the moon pool working platform includes a platform top surface 1 and a support frame 7, the platform top surface 1 is a hollow frame, and directly leads to the moon pool below at a certain height, and the support frame 7 Supported under the top surface 4 of the platform, the footings of the support frame are installed around the moon pool. There is a movable door at the hollow frame, and the movable door includes two opposite door bodies 1. The two door bodies are connected to the top surface of the moon pool working platform through hinges 6 respectively. There is a through hole in the center of the two door bodies, and a clamping device is provided at the through hole for clamping the hard tube. The diameter of the through hole of the dodge door is designed according to the size of the hard pipe used in marine mining projects, and there is no need to fi...

Abstract

The invention relates to a deep-sea mining conveying hard pipe clamping and swinging device which is used for hard pipe arranging and recycling in the deep-sea mining engineering. The deep-sea miningconveying hard pipe clamping and swinging device is composed of a moon pool work platform, a movable door assembly, a movable slip, a universal joint, a hydraulic pump station and an electrical control system of the hydraulic pump station. The diameter of a through hole of a movable door is designed according to the size of hard pipes used in the sea mining engineering, and core supplementing or core changing is not needed. A perpendicular overturning oppositely-opening manner is adopted for opening and closing of the movable door, a hydraulic oil cylinder is installed below the moon pool workplatform for controlling the angle and speed of the movable door, and the space around the work platform is not occupied. The movable slip and the universal joint can be used for clamping a pipelineso as to facilitate butt joint, in addition, inclination or deflection with a certain angle of the pipeline in the horizontal direction can be compensated for, and the pipeline is prevented from beingextruded to bend or generate cracks under the underwater ocean current effect. By means of the deep-sea mining conveying hard pipe clamping and swinging device, conveying hard pipe arranging and recycling can be achieved, and therefore the work process can be accurate, reliable and coherent.

Description

technical field [0001] The invention relates to a clamping and swinging device for laying and recovering conveying hard pipes in deep sea mining engineering. Background technique [0002] In deep-sea mining projects, the water surface support system of deep-sea mining projects needs to deploy and recover a lot of equipment, including hard pipes, hoses, relay stations and lifting pumps, etc., which need to be screwed on the moon pool working platform and assembled before deployment and recovery. It also needs to be disassembled on the moon pool working platform. The deployment and recovery of hard pipes is the most important thing, and the process of laying and recovering hard pipes also occupies a considerable proportion of the working time of the entire water surface support system. Therefore, this process should meet the requirements of accuracy, reliability, coherence and speed . There are many technical problems involved in the deployment and recovery of hard pipes, su...
