[0022] First embodiment:

[0023] This embodiment discloses a superheater hoisting structure.

[0024] like Figure 1 As shown, the superheater hoisting structure is used for the superheater, and the superheater has a serpentine tube 1. Those skilled in the art can know that the technical solution of this embodiment can also be used for other heat exchange equipment with a serpentine tube 1, such as an economizer and a reheater.

[0025] like Figure 1 to Figure 3 As shown, the lifting structure includes a clamping plate 2 and a clamping block 3. The clamping plates 2 have two pieces, and the clamping blocks 3 have several groups. Each group of clamping blocks 3 is symmetrically arranged between the two clamping plates 2, and each group of clamping blocks 3 is arranged at intervals at the upper end and the lower end of the serpentine tube 1 along the length direction of the clamping plates 2. The clamping block 3 includes a groove 31, and the groove 31 is opened at the upper end and the lower end of the inner side of the clamping block 3, and the inner side refers to the side adjacent to the two symmetrical clamping blocks 3. The groove 31 is fan-shaped, and the radius is the same as the radius of the serpentine tube 1. Among them, the grooves 31 located around the serpentine tube 1 are close to the outer surface of the serpentine tube 1, and the clamping plates 2 and the clamping blocks 3 located at the same height are screwed.

[0026] like Figure 2As shown, exemplarily, two clamps 2 are arranged vertically and in parallel. First through holes 21 are provided on the clamps 2 at intervals along the length direction of the clamps 2. The clamping blocks 3 are provided at the upper and lower ends of all parallel pipes in the serpentine tube 1. The clamping block 3 includes a second through hole 32, which is transversely penetrated and provided in the middle of the clamping block 3, and when the clamping block 3 is fixed, the position of the second through hole 32 corresponds to the first through hole 21. The lifting structure also includes a first screw 6, which is threadedly connected to the first through hole 21 and the second through hole 32. Preferably, the angle corresponding to the fan shape of the groove 31 is 90°, so that the grooves 31 located around the serpentine tube 1 can completely surround the outer surface of the serpentine tube 1, and the supporting effect on the serpentine tube 1 is good.

[0027] During installation of this embodiment:

[0028] The clamping block 3 is symmetrically inserted into the upper and lower ends of all parallel pipes in the serpentine tube 1, so that the grooves 31 located around the serpentine tube 1 are close to the outer surface of the serpentine tube 1, and the clamping plates 2 are placed on both sides of the serpentine tube 1, and the first through hole 21 of the clamping plate 2 is aligned with the second through hole 32 of the clamping block 3. The first screw 6 is threadedly connected to the first through hole 21 and the second through hole 32, and the clamping plate 2 and the clamping block 3 are fixed together, and at the same time, the serpentine tube 1 is fixed in the inscribed circle enclosed by the groove 31.

[0029] The lifting structure of this embodiment connects the clamping plate 2 and the clamping block 3 at the same height by screws, has a simple structure, and is easy to install and disassemble. The serpentine tube 1 is fixed in the inscribed circle enclosed by the groove 31, which can prevent the serpentine tube 1 from deformation, and the position and size of the clamping block 3 can be adjusted to meet different pipe diameters and pipe spacings.

[0030] Second embodiment:

[0031] Based on the first embodiment, the second embodiment is further optimized and refined.

[0032] like Figure 2 As shown, further, the hoisting structure also includes a connecting block 4, which is arranged at the upper end between the two clamping plates 2. The clamping plates 2 and the connecting block 4 are screwed.

[0033] Exemplarily, the connection block 4 includes a third through hole 43, which runs transversely through the connection block 4. When the connection block 4 is fixed, the position of the third through hole 43 corresponds to the first through hole 21, and the connection block 4 is flush with the upper end of the clamping plate 2. The lifting structure includes a second screw 7, which is threadedly connected to the first through hole 21 and the third through hole 43. The connection block 4 can also be arranged at the lower end between the two clamping plates 2 to facilitate the placement of the superheater.

[0034] like Figure 2As shown, further, the hanging structure includes a top plate 8, and the top plate 8 is located at the upper end of the hanging structure. The connecting block 4 includes a screw rod 41 and a double nut 42. The screw rod 41 is arranged at the upper end of the connecting block 4 and passes through the top plate 8. The double nut 42 is screwed into the upper end of the screw rod 41 to fix the clamping plate 2 on the top plate 8.

[0035] Further, the lifting structure also includes a lifting lug 5, which is threadedly connected to the screw rod 41. Exemplarily, the lifting lug 5 includes a ring body 51 and a connecting portion 52 connected to the lower end of the ring body 51, a fourth through hole (not marked in the figure) is provided in the connecting portion 52, and the screw rod 41 is threadedly connected to the fourth through hole.

[0036] In this embodiment, when lifting is required, the threaded lifting ear 5 on the screw 41 can be used to lift the superheater through a crane. When lifting and fixing is required, the screw 41 passes through the top plate 8, and the double nut 42 is screwed into the top of the screw 41 and tightened to fix the connecting block 4 and the top plate 8 together to achieve the lifting of the superheater.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
