Track assembly positioning mechanism of four-track tensioner system and positioning method of track assembly positioning mechanism

Abstract

The invention belongs to the technical field of submarine line laying equipment, in particular to a track assembly positioning mechanism of a four-track tensioner system. The track assembly positioning mechanism comprises a limiting sensor (1), a pulley assembly (25) and a positioning base (4), wherein the pulley assembly (25) comprises an axle seat (2); a core shaft is fixedly mounted on the axle seat (2), and is sleeved with a shaft sleeve (3); the axle seat (2) is fixedly mounted at one side, close to a right track frame (28), of an upper track frame (24); the positioning base (4) is fixedly mounted at the top of the inner end of the right track frame (28); a V-shaped groove is formed in the top of the positioning base (4); the inner surface of the V-shaped groove extends towards the inclined upside of the inner side to form an inclined guide face; and when the shaft sleeve (3) slides to the bottom of the V-shaped groove along the inclined guide face, the limiting sensor (1) senses the position of the axle seat (2) and produces a trigger signal. The invention also relates to a positioning method of the track assembly positioning mechanism.

Description

technical field [0001] The invention belongs to the technical field of submarine pipeline laying equipment, and in particular relates to a positioning mechanism of a crawler belt assembly of a four-track tensioner system; the invention also relates to a positioning method of the above positioning mechanism. Background technique [0002] In deepwater oil and gas development, there are more and more offshore pipelaying operations and their importance is becoming increasingly prominent. Tensioners are professional equipment for offshore pipe-laying operations and play an important role in the process of laying pipelines (such as oil pipelines, umbilical cables, etc.). The four-track tensioner has a large contact area between the tracks and the pipeline, which has a small surface stress on the pipeline and has a good protective effect on the pipeline. It is mainly used for laying flexible pipes and umbilical cables. However, there is a joint UTA assembly at the end of the umbil...

Problems solved by technology

[0006] The advantages and positive effects of the present invention are: the present invention provides a crawler belt assembly positioning mechanism of a four-track tensioner system and a positioning method thereof. The positioning mechanism of the overturning device is compact in structure and can be installed in a narrow space. Angle design positioning base slope and positioning groove solve the problem of tilting and inability to position the upper crawler assembly due to cumulative machining errors and other reasons
