Abstract

The invention discloses a device for detecting the coaxiality of an offshore riser clamp, and the device comprises a first sleeve, second sleeves, a detection disc, and the first sleeve which is provided with a fastening assembly and chutes. The two second sleeves are arranged in the first sleeve side by side in the axial direction of the first sleeve, limiting assemblies are fixed to the second sleeves, the limiting assemblies are clamped in the chutes and can freely slide along the chutes, and the second sleeves can be fixed to a certain position in the first sleeve under the action of the fastening assembly; and the detection disc is used for measuring the coaxiality of the plurality of vertical pipe clamps. The device disclosed by the invention can be used for detecting the coaxialityof a plurality of vertical pipe clamps, and is simple to operate, time-saving, labor-saving, wide in application range and smaller in error.

Description

technical field [0001] The invention relates to a special tool for offshore equipment, in particular to a detection device for the coaxiality of clamps of offshore risers. Background technique [0002] When installing pipelines on offshore oil exploration platforms, multiple riser clips need to be installed. After the riser clips are installed, the concentricity of all underwater clips and surface clips needs to be adjusted to facilitate the subsequent installation of risers or cable protection pipes. . [0003] The traditional coaxiality adjustment methods mainly include the simulated riser method and the steel wire measurement method: (1) The simulated riser method is also the first method used. It is necessary to use a trial installation pipeline with the same outer diameter and length as the standpipe. The corresponding position of the standpipe clip is simulated and installed in kind, so as to adjust the coaxiality of the standpipe clip. It consumes a lot of manpower,...
