Underwater Pipeline Connection Robot

Abstract

The invention provides an underwater pipeline connection robot. The underwater pipeline connection robot mainly solves the problems of complicated connection system and various tools of the existing underwater pipeline connection robot. The utility model is characterized in that the robot adopts a frame structure of a triangular crawler, and the triangular crawler can be adapted to the complicatedterrain environment of the seafloor; Hydraulically driven mechanical jaws are installed on both sides to realize the clamping of the pipeline, The two pipelines can reach the same horizontal height by using the double-axis oil cylinder lifting mechanism, and the double-axis oil cylinder structure is more stable and can prevent the circumstance of rotation under water. The sliding rail mechanism and the hydraulic cylinder are used together to make the pipelines move to the left and the right for position adjustment. Make the two pipes to be connected face to face, and clamp connectors arrangedin the middle of the robot will lock the two pipes in alignment to realize the pipe connection function. The robot can accomplish underwater walking, pipe clamping, pipe alignment and pipe connection, and adopts hydraulic driving mode as a whole, which not only has high machine power, but also has higher stability.

Description

technical field [0001] The invention relates to an underwater pipeline connection robot. Background technique [0002] With the rapid development of my country's economy, the demand for energy, especially oil resources, continues to grow. Under the circumstance that land oil and gas resources are decreasing day by day, the development of offshore oil and gas has become an important guarantee for my country's energy security. Deep-sea oil and gas pipelines play a very important role in the storage and transportation of deep-water oil and gas. Due to the limitation of the variability of the marine environment, the laying of deep-sea pipelines has high requirements on the process and engineering quality, in order to achieve the goal of shortening the offshore construction period and reducing engineering development costs. Deep-sea oil and gas pipelines mainly have two methods: welding and mechanical connection. At present, several methods commonly used in underwater welding me...

AI Technical Summary

Problems solved by technology

At present, my country's underwater pipeline connection operation and research are still in their infancy. Underwater pipelines are usually welded and connected on land before they are consigned to the seabed by a ship, or they are connected by a pipe-laying ship on a ship and then lowered. In water, these two methods are complicated, time-consuming and labor-intensive, far from meeting the standards of modern automation levels

Most of the existing underwater pipeline connection systems require the cooperation of underwater auxiliary robots to complete the work. In the process of grabbing, It is coherent and affects the efficiency and work process of the connection
