Problems solved by technology
In the conventional method, the fixed connecting rods between the stingers are replaced, and the relative angle between the stingers is adjusted by the length of the fixed connecting rods. This usually requires a large floating crane to complete the disassembly and installation of the fixed connecting rods, and also requires manual work. Collaborative operation and cooperation, high risk factor and many environmental requirements

The invention provides a stinger angle adjustment system, which comprises a first stinger, a second stinger, a main push oil cylinder and a connecting rod box body. The first stinger and the second stinger are hinged to two sides of the main push oil cylinder; the connecting rod box body comprises an outer box body and an inner box body sleeved inside the outer box body; the first stinger and the second stinger are respectively hinged to one sides of the outer box body and the inner box body; the connecting rod box body also comprises a locking device, which can be switched between an unlocking state and a locking state; under the unlocking state, the main push oil cylinder can adjust an angle between the first stinger and the second stinger, so that the outer box body and the inner box body can axially slide relatively; under the locking state, the outer box body and the inner box body are mutually fixed. The stinger angle adjustment system provided by the invention can be convenient to adjust a relative angle between the stingers, so that the manual operation is reduced, and the safety is improved.
Description
technical field [0001] The invention belongs to the technical field of submarine pipeline laying, and relates to a stinger angle adjustment system. Background technique [0002] In the process of underwater oil and gas development, a large number of submarine pipelines are required. The S-LAY pipe laying method is the mainstream submarine pipeline laying method. When S-lay is adopted, the stinger is one of the key equipment, and the stinger is used to support the pipeline. And guide the pipeline into the water according to the required angle and bending radius, so as to realize the reasonable deformation of the pipeline during laying and ensure the safety of the pipeline. [0003] During the laying of submarine pipelines, the stinger system generally includes two to three stingers, and changing the relative angle between every two stingers can change the bending radius of the stinger system. In the conventional method, the fixed link between the stingers is replaced, and th...
