[0027] See also Figure 1-5 ,The utility model provides a technical solution:

[0028] A split flange comprises an upper flange 1, wherein the bottom of the upper flange 1 is threadedly connected to a lower flange 2, a neck 3 is fixedly provided in the middle of the top of the upper flange 1, a flange ring assembly 4 threadedly connected to the upper flange 1 is arranged on the circumferential outer wall of the neck 3, and the flange ring assembly 4 comprises a flange connecting ring 401 and a flange plug ring 402, both ends of the side walls of the flange connecting ring 401 are provided with interfaces 403, both ends of the side walls of the flange plug ring 402 are fixed with plugs 404, the top of the interface 403 and the top of the plug 404 are provided with screw holes 405, the circumferential inner wall of another screw hole 405 is threadedly connected to a screw rod 406, a card slot 407 is provided on one side of the top of the plug 404, a plurality of through holes 5 are provided in an annular array on the top of the upper flange 1, the lower flange 2, and the flange ring assembly 4, and a card connection assembly 6 is slidably connected inside the card slot 407. The utility model connects the flange connecting ring 401 and the flange plug ring 402 by inserting the plug 404 into the interface 403, and uses the screw 406 to be screwed into the screw hole 405 to fix the flange connecting ring 401 and the flange plug ring 402, and sets the flange ring assembly 4 on the outer wall of the circumference of the neck platform 3, and places the lower flange plate 2 on the bottom of the upper flange plate 1, and passes the bolts through the through holes 5 on the top of the upper flange plate 1, the lower flange plate 2, and the flange ring assembly 4, so as to connect the split flange.

[0029] Specifically, the clamping assembly 6 includes a pressing plate 601, a moving rod 602 is fixedly provided on the side wall of the pressing plate 601, a spring 603 is fixedly provided on the side wall of the pressing plate 601 and is sleeved on the outer circumference of the moving rod 602, a handle 604 is fixedly provided on the other end of the moving rod 602, and a fixing frame 605 is fixedly provided on the outer wall of both ends of the flange connecting ring 401, and a limiting plate 606 is fixedly provided on the other end of the fixing frame 605 and is sleeved on the outer circumference of the moving rod 602. By manually pulling the handle 604, the moving rod 602 drives the pressing plate 601 to move outward, and after the plug 404 is inserted into the interface 403, the handle 604 is released, and the rebound force of the spring 603 drives the pressing plate 601 to press against the inner wall of the card slot 407, so that the connection between the flange connecting ring 401 and the flange plug ring 402 is more stable, and the position of the spring 603 is limited by the limiting plate 606 to prevent it from being separated.

[0030] Furthermore, the size of the interface 403 matches that of the plug 404, and the position of the screw hole 405 opened at the top of the interface 403 matches that of the top of the plug 404. The size matching of the interface 403 and the plug 404 makes the connection between the flange ring 401 and the flange plug ring 402 tighter.

[0031] It is worth noting that the number of through holes 5 opened on the top of the upper flange 1, the lower flange 2 and the flange ring assembly 4 is the same and the positions are matched. The through holes 5 with matching positions facilitate the threaded connection of the bolts.

[0032] It is worth noting that a limiting groove 101 is provided at the bottom of the upper flange 1, and a limiting ring 201 is fixed at the top of the lower flange 2. The limiting groove 101 and the limiting ring 201 limit the positions of the upper flange 1 and the lower flange 2, so as to facilitate the connection of the split flange.

[0033] In addition, the limiting groove 101 and the limiting ring 201 are both arranged between the through hole 5 and the flange hole, and the size and position of the limiting groove 101 match the size and position of the limiting ring 201. By arranging the limiting groove 101 and the limiting ring 201 between the through hole 5 and the flange hole, the connection between the shafts is prevented from being affected during the split flange connection.

[0034] Working principle: When the device is required to perform split flange connection, the staff manually pulls the handle 604 to make the moving rod 602 drive the pressure plate 601 to move outward, insert the plug 404 into the interface 403 to connect the flange ring 401 and the flange plug ring 402, release the handle 604, and drive the pressure plate 601 to press against the inner wall of the slot 407 through the rebound force of the spring 603, so that the connection between the flange ring 401 and the flange plug ring 402 is more stable, and the limit plate 60 6 limits the position of spring 603 to prevent it from detaching, and uses screw 406 to screw into screw hole 405 to fix flange connecting ring 401 and flange insert ring 402, and sets flange ring assembly 4 on the outer wall of the circumference of neck platform 3, and places lower flange plate 2 on the bottom of upper flange plate 1. Limiting groove 101 and limiting ring 201 define the position of upper flange plate 1 and lower flange plate 2, and use bolts to pass through the through hole 5 on the top of upper flange plate 1, lower flange plate 2 and flange ring assembly 4, so as to connect the split flange.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
