[0023] When in use, when connecting the main pipes 1, first insert the limit rod 5 into the installation groove 3, then the limit rod 5 will push the limit rods 5 on both sides, and then the limit rod 5 will be stuck in one side of the limit block 401, so as to complete the limit. When the limit needs to be released, the pull rod 403 can be moved to both sides, and the limit rod 5 can be pulled out at this time. The limit mechanism 4 can make the connection between the connecting flanges 2 more stable, and it can also prevent the main pipe 1 from suddenly falling due to gravity after multiple bolts are removed during disassembly, thereby improving the equipment. The use efficiency is improved, and the operating difficulty of personnel is reduced. When the inner core 10 needs to be inspected, repaired or replaced, the rotating rod 901 can be rotated. When the rotating rod 901 rotates, it will drive the transmission block 902 to move. At this time, the transmission block 902 will drive one end of the connecting rod 903 to move. At this time, the support plate 905 will be away from the inner core 10. Thereafter, the inner core 10 can be pulled out for repair and maintenance, thereby reducing the working difficulty of personnel. At the same time, the inner cores 10 can be separated from each other by the supporting mechanism 9, thereby reducing the wear between the inner cores 10.

[0024] like Figure 2-4As shown, the support mechanism 9 includes a rotating rod 901, a transmission block 902, a connecting rod 1 903, a connecting rod 2 904 and a support plate 905.

[0025] When docking the main pipes 1, first insert the limit rod 5 into the installation groove 3. At this time, the limit rod 5 will push the limit rods 5 on both sides. Thereafter, the limit rod 5 will be stuck in one side of the limit block 401 to complete the limit. When the limit needs to be released, the pull rod 403 can be moved to both sides. At this time, the limit rod 5 can be pulled out. The limit mechanism 4 can make the docking between the connecting flanges 2 more stable. At the same time, it can also prevent the main pipe 1 from suddenly falling due to gravity after multiple bolts are removed during disassembly, thereby improving the use efficiency of the equipment and reducing the difficulty of operation for personnel.

[0027] When the inner core 10 needs to be inspected, repaired or replaced, the rotating rod 901 can be rotated. When the rotating rod 901 rotates, it will drive the transmission block 902 to move. At this time, the transmission block 902 will drive one end of the connecting rod 903 to move. At this time, the support plate 905 will be away from the inner core 10. Thereafter, the inner core 10 can be pulled out for repair and maintenance, thereby reducing the difficulty of the personnel's work. At the same time, the inner cores 10 can be separated from each other by the support mechanism 9, thereby reducing the wear between the inner cores 10.

[0028] Here’s how it works:

[0029] First, insert the limit rod 5 into the installation groove 3, and the limit rod 5 will push the limit rods 5 on both sides. Thereafter, the limit rod 5 will be stuck in one side of the limit block 401 to complete the limit. When the limit needs to be released, the pull rod 403 can be moved to both sides. At this time, the limit rod 5 can be pulled out, and the connection between the connecting flanges 2 can be made more stable through the limit mechanism 4. When the inner core 10 needs to be inspected, repaired or replaced, the rotating rod 901 can be rotated. When the rotating rod 901 rotates, it will drive the transmission block 902 to move. At this time, the transmission block 902 will drive one end of the connecting rod 903 to move. At this time, the support plate 905 will be away from the inner core 10, and thereafter the inner core 10 can be pulled out for repair and maintenance.
