An automatic locating synchronous lead-in device for a submarine pipeline flange bolt comprises a gear ring, an upper body plate, lower body plates, a pair of upper supporting plates and a pair of lower supporting plates. The upper body plate is arranged below the gear ring, the lower body plates are arranged below the upper body plate, the upper supporting plates are mounted at the left end and the right end of the upper body plate respectively, and the lower supporting plates are mounted at the left end and the right end of the upper body plate respectively. An upper bolt base is arranged on the periphery of a submarine pipeline inlet hole. The lower body plates comprise a left body plate and a right body plate mounted in cooperation with the left body plate. The left body plate and the right body plate body are each provided with a bolt base. Hydraulic cylinders are in pin joint between the upper supporting plates and the lower supporting plates. Bolt fixing sleeves are arranged on the upper bolt base, the left bolt base and the right bolt base, one end of each bolt fixing sleeve is connected with the upper body plate, the left body plate and the right body plate, and a plurality of bolts are mounted at the other ends of the bolt fixing sleeves. Check bolts can be automatically clamped in bolt grooves in the deep sea, and the aim of fixed connection of the check bolts is achieved. The connecting stability of the check bolts and the underwater work efficiency of operating personnel are greatly improved.
Description
technical field [0001] The invention relates to an automatic connection tool, in particular to an automatic positioning and synchronous introduction device for flange bolts of seabed pipelines. It belongs to the technical field of offshore oil engineering. Background technique [0002] At present, since there is no special connection device for the flange connection of deep-water submarine pipelines, lockbolts are usually used to realize the connection of submarine pipeline flanges through the compression of the lockbolt compression mechanism. Because the clamping mechanism does not match the anti-loosening bolt, it not only brings trouble to the operator's compression under the seabed working conditions, but also the anti-loosening bolt cannot achieve a completely stable effect. Contents of the invention [0003] The main purpose of the present invention is to overcome the above-mentioned shortcomings existing in the prior art, and to provide an automatic positioning and...
