[0037] Further, in the present embodiment, a limiting structure 24 is provided on the turning frame 20, and the limiting structure 24 can be used to limit the horizontal connector. In some embodiments, the limiting structure 24 can be arranged on the frame body 21, and located on the side of the locking structure 23 away from the rotating shaft support structure 13. In some embodiments, the limiting structure 24 can be two groups, and the two groups of limiting structures 24 can be arranged at intervals along the radial direction of the horizontal connector, can be located on two opposite sides of the horizontal connector, and can cooperate with each other to limit the horizontal connector, which can be used to prevent the horizontal connector from sliding out from the side when turning over on the turning frame. In some embodiments, the limiting structure 24 can be a limiting baffle, and the limiting baffle can be welded to the frame body 21.

[0038] Further, in the present embodiment, the turning frame 20 further includes a first support structure 25 disposed on the frame body 21, and the first support structure 25 can support the entire turning frame 20 when the turning frame 20 is turned over 90 degrees.

[0040] Furthermore, in this embodiment, the turning frame 20 further includes a second supporting structure 27, which can be disposed at the bottom of the frame body 21 and can support the turning frame 20 when the turning frame 20 is in the initial position. In some embodiments, the second supporting structure 27 can be a plurality of supporting legs.

[0041] Figures 4 to 6 A second embodiment of the horizontal connector flipping and centering mechanism of the present invention is shown, which differs from the first embodiment in that the turning frame 20 can be a terminal horizontal connector turning frame, which can be used for the installation of the terminal horizontal connector and play a supporting role for the terminal horizontal connector.

[0042] In the present embodiment, a guide positioning member 15 is detachably provided on the base 10, and the guide positioning member 15 can be used to guide the turning frame 20 to turn over. In some embodiments, the guide positioning member 15 can be provided on the second base body 12, and can be detachably connected to the second base body 12. Specifically, the guide positioning member 15 can be a guide column, and the guide column can be provided in a direction perpendicular to the second base body 12, and can be installed on the fourth support beam 122, and can be detachably connected to the fourth support beam 122 by providing a connecting component, and in some embodiments, the connecting component can be a screw or a bolt. When installing the end horizontal connector, the guide column can be used to guide the turning frame 20, so that the turning frame 20 will not rotate forward and backward during the height adjustment process.

[0043] In this embodiment, the locking structure 23 can be disposed at one end of the frame body 21 away from the rotating shaft support structure 13. The support column 212 can be provided with a guide hole 2121 for cooperating with the guide positioning member 15 for guidance. When the turning frame 20 is turned over, the guide positioning member 15 can pass through the guide hole 2121 and then cooperate with the guide positioning member 15.

[0044] When the horizontal connector flipping and centering mechanism is implemented, the head-end horizontal connector is placed on the head-end connector turning frame, ensuring that the horizontal connector is supported on the limit structure 24, and the locking structure 23 is closed and the bolts are tightened. The horizontal connector is fixed to the turning frame 20 with two binding straps, and the rotating shaft 22 of the turning frame 20 is locked with bolts. The door-type hanger is installed on the horizontal connector and maintained at a certain angle, and then the base 10, the turning frame 20, the horizontal connector and the door-type hanger are hoisted as a whole to the predetermined installation position on the moon pool cover. The turning frame 20 is flipped by increasing the height and moving direction of the auxiliary crane hook. When the diagonal support of the turning frame 20 is supported on the limit block, the flipping is suspended and the drag head of the hose is removed. Connect 4 hand chain hoists to the turning frame 20, two at the front and two at the back, the front two are used to continue turning over, and the back two are slowly extended to cooperate until the turning frame 20 is completely vertical. At this time, the front end of the turning frame 20 is supported on the base 10, and the position of the base 10 is fine-tuned by the lifting lugs on the base 10, so that the flange of the hose and the flange center on the horizontal connector are aligned and connected. After the connection is completed, remove the bolts of the locking structure 23 of the turning frame 20 and the binding belt for binding the horizontal connector, and pull up the hose and the horizontal connector. Move the base 10 so that the turning frame 20 and the horizontal connector are pulled apart enough, and then adjust the 4 hand chain hoists to slowly lower the turning frame 20 to the initial position. Remove the connecting bolts of the front and rear parts of the base 10, remove the front and rear parts, so as to open the moon pool cover and carry out the subsequent laying of the hose. The use process of the end horizontal connector turning frame is basically similar to the above process, and will not be repeated here.

[0045] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
