Abstract
Claims
1. A connecting device for opening and closing a flat cover of a pressure vessel, characterized in that, The system includes a base on which a load-bearing main shaft is fixed. From top to bottom, the main shaft is rotatably fitted with a deep groove ball bearing, an outer shell sleeve, and a self-aligning roller bearing. The deep groove ball bearing outer shell is covered by the deep groove ball bearing sleeve, and the self-aligning roller bearing outer shell is covered by the self-aligning roller bearing sleeve. The deep groove ball bearing sleeve, the outer shell sleeve, and the self-aligning roller bearing sleeve are welded together. A triangular hinge seat is welded to the outer contour of the outer shell sleeve, and the triangular hinge seat is connected to the end of the hydraulic rod of the hydraulic cylinder via a pin hinge. A stiffening plate is also welded to the outer contour of the outer shell sleeve, and the end of the stiffening plate not connected to the outer shell sleeve is detachably connected to a flat cover for sealing a pressure vessel.
2. The connecting device for opening and closing the flat cover of a pressure vessel according to claim 1, characterized in that, The base has an upwardly protruding boss, and the boss has a groove recessed inward from the platform surface to fit the shape of the load-bearing main shaft, and the load-bearing main shaft is fixed in the groove; the self-aligning roller bearing sleeve is placed on the platform surface of the boss.
3. The connecting device for opening and closing the flat cover of a pressure vessel according to claim 2, characterized in that, The deep groove ball bearing sleeve, the outer shell sleeve, and the self-aligning roller bearing sleeve are all cylindrical and have the same outer diameter.
4. The connecting device for opening and closing the flat cover of a pressure vessel according to claim 3, wherein The surface of the boss and the bottom surface of the self-aligning roller bearing sleeve are coated with lubricating oil.
5. A connecting device for opening and closing a pressure vessel flat cover according to claim 1, characterized in that, The triangular hinge is a double-eared joint hinge. The end of the hydraulic rod of the hydraulic cylinder is fixed with a single-eared plate. The center of the single-eared plate and the double-eared joint hinge is provided with a through hole of the same size. The single-eared plate is clamped in the double-eared joint hinge, and the center of the through hole of the single-eared plate clamp and the through hole of the double-eared joint hinge are on the same axis. The pin is inserted into the through hole of the single-eared plate clamp and the through hole of the double-eared joint hinge.
6. The connecting device for opening and closing the flat cover of a pressure vessel according to claim 1, wherein The angle between the side of the triangular hinge closest to the rib and the rib is an obtuse angle.
7. The connecting device for opening and closing the flat cover of a pressure vessel according to claim 1, wherein The end of the hydraulic cylinder furthest from the hydraulic rod is hinged to a support column so that the line connecting the end of the hydraulic cylinder furthest from the hydraulic rod and the end of the hydraulic rod is parallel to the horizontal plane.
8. The connecting device for opening and closing the flat cover of a pressure vessel according to claim 1, characterized in that, The end of the stiffener not connected to the outer casing is welded with a connector, the connector having a connecting plate adapted to the opening of the pressure vessel, and the flat cover is detachably connected to the connecting plate by bolts.
