Embodiment one of a tray mechanism for hoisting the heat-insulating lining of the alkane dehydrogenation reactor comprises:
as shown in fig. 1 to 4, a tray mechanism for hoisting a thermal insulation lining of an alkane dehydrogenation reactor comprises a tray body 1 and a plurality of movable connecting plates 2, wherein the tray body 1 is disc-shaped, the movable connecting plates 2 are rectangular plate-shaped, the movable connecting plates 2 are provided with a plurality of movable connecting plates 2, the plurality of movable connecting plates 2 are uniformly distributed on the tray body 1 along the circumferential direction, through holes 11 are formed in the tray body 1, screw portions 31 of bolts 3 penetrate through the corresponding through holes 11 and then overhang the tray body 1, heads 32 of the bolts are welded and fixed on the lower end surface of the tray body 1, long slotted holes 21 for the corresponding screw portions to penetrate are formed in the movable connecting plates 2, the width of the long slotted holes is equal to the diameter of the screw portions, so that the movable connecting plates 2 can be guided and moved along the radial direction of the tray body 1, the extending direction of the long slotted holes 21 is consistent with the radial moving direction of the corresponding movable connecting plates, and the movable connecting plates can be relatively pressed and fixed with the tray body after the nuts 4 are in threaded connection with the screw portions 31; when the position of the movable connecting plate needs to be adjusted, the nut 4 is loosened, the position of the screw part 31 in the long groove hole 21 is adjusted, and then the nut 4 is screwed again to enable the movable connecting plate to be pressed with the tray body relatively. The end part of the movable connecting plate 2 far away from the tray body is provided with a supporting plate 5, the supporting plate 5 extends along the radial direction, the supporting plate 5 can be integrally formed with the movable connecting part 2, or the supporting plate 5 and the movable connecting plate 2 are welded and fixed, and the length of the supporting plate 5 can be larger than the width of the movable connecting plate 2 so as to form a T-shaped plate structure. The baffle 6 is welded on the supporting plate 5, the baffle 6 is close to the movable connecting plate 2, the baffle extends along the vertical direction, namely the baffle is perpendicular to the supporting plate, the baffle is used for abutting against the inner wall of the heat insulation lining, and the heat insulation lining is prevented from deflecting or shifting relative to the tray body in the lifting process. The upper end face of tray body 1 is equipped with a plurality of rings 7 of circumference equipartition, and rings are used for cooperating crane or overhead traveling crane to hoist tray mechanism and thermal-insulated inside lining.
In this embodiment, swing joint board is provided with four, and the contained angle of two adjacent swing joint boards of circumference is 90 to provide the support stability ability of preferred to thermal-insulated inside lining in hoist and mount process. The lifting rings are four, and one lifting ring is arranged between two circumferentially adjacent movable connecting plates so as to improve the stability during lifting. It is worth explaining that the utility model does not limit the number of the movable connecting plates, when the size and the weight of the heat insulation lining are smaller, at least two movable connecting plates which are distributed relatively can be adopted; generally, three or more than three movable connecting plates are adopted to ensure stable support during lifting.
The utility model discloses a theory of operation as follows:
when the tray mechanism is used, the tray mechanism is placed into the heat insulation lining 9, the heat insulation lining is generally a hollow cylinder (figure 13A), a hollow circular truncated cone (figure 13B) or a hollow circular truncated cone (figure 13C) with an arc-shaped bus, then the heat insulation lining is lifted manually, for example, the heat insulation lining at the position of each movable connecting plate can be lifted or tilted one by one according to the position of the movable connecting plate, the movable connecting plate is pushed outwards in the radial direction, a supporting plate corresponding to the end part of the movable connecting plate is inserted into the lower end face (as figure 10) of the heat insulation lining, the baffle is abutted against the inner wall of the heat insulation lining, then a corresponding nut is locked, and the radial position of the movable connecting plate is fixed. After the supporting plate and the baffle plate at the end part of each movable connecting plate are matched with the heat insulation lining, the lifting hook of a crane or a crown block is hung on the lifting ring, and then the lifting flow of the heat insulation lining can be carried out. Because the radial position of the movable connecting plate relative to the tray body can be adjusted, the tray can adapt to heat insulation lining prefabricated products with various sizes, and the working efficiency is greatly improved.
An embodiment two of the tray mechanism for hoisting the heat-insulating lining of the alkane dehydrogenation reactor comprises:
