Description

Technical Field

[0001] This utility model relates to the field of turbine insulation layer hoisting technology, and in particular to a turbine insulation layer device that facilitates hoisting. Background Technology

[0002] Steam turbines are the main equipment in modern thermal power plants, and are also used in the metallurgical industry, chemical industry, and ship propulsion systems. Because steam turbines require high heat and high pressure to operate, they need to be covered with an insulation layer.

[0003] The existing patent, CN218376591U, describes a steam turbine insulation layer that is easy to hoist. This patent uses eight sets of rubber waterstop strips, which allow the liquefied water vapor to be absorbed by the rubber waterstop strips. The principle of the rubber waterstop strips expanding when exposed to water also improves the tightness of the fit between the four sets of protrusions and the four sets of grooves, thereby enhancing the overall airtightness of the device.

[0004] In their daily work, the inventors discovered that the hooks in the aforementioned patents are fixed structures. After the insulation layer is installed, the fixed hooks do not protrude continuously. When the turbine installation space is small, the hooks are prone to interfering with surrounding equipment, affecting the installation process, thus making them unsuitable for use in narrow spaces. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned above in the background art by proposing a steam turbine insulation layer device that is convenient for hoisting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a turbine insulation layer device that is easy to hoist, comprising an insulation layer body, a first arc-shaped fixing member, a second arc-shaped fixing member, and two limiting strips. The surface of the first arc-shaped fixing member is provided with a rotating storage device. The rotating storage device includes a fixing seat fixedly installed on the surface of the first arc-shaped fixing member. The surface of the fixing seat is provided with a storage groove. A rotating shaft is rotatably connected between the inner walls of the two sides of the storage groove. A rotating plate is fixedly installed on the outer wall surface of the rotating shaft. A lifting ring is fixedly installed on the side of the rotating plate.

[0007] Preferably, two U-shaped plates are fixedly installed on one side surface of the fixing base, and a threaded rod is rotatably connected between the inner walls of the two ends of one of the U-shaped plates, and a rotating wheel is fixedly installed at one end of the threaded rod.

[0008] Preferably, a sliding rod is fixedly installed between the inner walls of the two ends of another U-shaped plate, and a T-shaped plate is threadedly connected to the surface of the threaded rod. The sliding hole of the T-shaped plate is clearance-fitted with the sliding rod, and linear sliding is achieved by means of the rotation of the threaded rod and the guidance of the sliding rod.

[0009] Preferably, a plug is fixedly installed on the surface of the T-shaped plate, and a plurality of plug holes matching the plug are distributed in a ring on the outer wall surface of the rotating shaft.

[0010] The aforementioned components achieve the following effects: by using a rotating wheel to drive the threaded rod and the T-shaped plate to adjust the locking state of the insertion rod and the insertion hole, the lifting ring can be rotated and stored in the storage slot of the fixed base. This ensures stable force distribution on the lifting ring during lifting by locking it through the insertion hole, and allows the lifting ring to be stored after the operation to prevent protrusion and interference. This achieves a balance between ease of lifting operation, structural stability, and spatial adaptability.

[0011] Preferably, each of the two limiting strips is provided with a fixing device, the fixing device including two slots formed on the surfaces of the two limiting strips, the dimensions of the two slots matching the dimensions of the extensions on both sides of the first arc-shaped fixing member and the second arc-shaped fixing member.

[0012] Preferably, extension plates are fixedly installed on both sides of the two limiting strips, and the extension plates on both sides of the limiting strips are staggered vertically.

[0013] Preferably, bolts are threaded onto the surfaces of all four extension plates, and two threaded holes matching the bolts are provided on one side surface of both the first and second arc-shaped fixing members, with the threaded holes on one side surface of the first and second arc-shaped fixing members being positioned opposite to each other.

[0014] The effect achieved by the above components is that the limiting strip is interference-fitted with the extension of the arc-shaped fixing part through the slot, and then fixed with bolts. Only four bolts need to be turned to complete the clamping, fixing or disassembly of the insulation layer body, which significantly improves work efficiency.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, by setting up a rotating storage device, the screw rod driven by the rotating wheel drives the T-shaped plate to adjust the locking state of the insertion rod and the insertion hole, so that the lifting ring can be rotated and stored in the storage groove of the fixed base. This not only ensures the stable force of the lifting ring by locking it through the insertion hole during hoisting, but also allows the lifting ring to be stored after the operation to avoid protrusion and interference, thus achieving a unity of hoisting operation convenience, structural stability and spatial adaptability.

[0024] Example 1, such as Figure 1-6 As shown, a turbine insulation layer device that is easy to hoist includes an insulation layer body 1, a first arc-shaped fixing component 4, a second arc-shaped fixing component 5, and two limiting strips 6. The insulation layer body 1 is made of 100mm thick aluminum silicate fiber material, with an aluminum foil reflective layer on the surface, which is adapted to the arc-shaped contour of the turbine outer wall. The first arc-shaped fixing component 4 and the second arc-shaped fixing component 5 are both stamped from Q235 steel plate, with an arc R=600mm and a fitting error with the turbine outer wall ≤2mm.

[0025] Reference Figure 4-6As shown in this embodiment: the surface of the first arc-shaped fixing member 4 is provided with a rotating storage device 2. The rotating storage device 2 includes a fixing seat 201 fixedly installed on the surface of the first arc-shaped fixing member 4. A storage groove 202 is opened on the surface of the fixing seat 201. A rotating shaft 203 is rotatably connected between the inner walls of the two sides of the storage groove 202. A rotating plate 204 is fixedly installed on the outer wall surface of the rotating shaft 203. A lifting ring 205 is fixedly installed on the side of the rotating plate 204. Two U-shaped plates 206 are fixedly installed on one side surface of the fixing seat 201. A threaded rod 20 is rotatably connected between the inner walls of the two ends of one of the U-shaped plates 206. 7. A rotating wheel 208 is fixedly installed at one end of the threaded rod 207. A sliding rod 209 is fixedly installed between the inner walls of the two ends of another U-shaped plate 206. A T-shaped plate 210 is threadedly connected to the surface of the threaded rod 207. The sliding hole of the T-shaped plate 210 is clearance-fitted with the sliding rod 209. Linear sliding is achieved by rotating the threaded rod 207 and guiding it with the sliding rod 209. An insert rod 211 is fixedly installed on the surface of the T-shaped plate 210. Multiple insertion holes 212 matching the insert rod 211 are distributed in a ring on the outer wall surface of the rotating shaft 203. The thread pitch of the threaded rod 207 is 2mm, which is compatible with the thread hole accuracy of the T-shaped plate 210.

[0026] Reference Figure 2-5 As shown in this embodiment: The surfaces of both limiting strips 6 are provided with fixing devices 3. Each fixing device 3 includes two slots 31 formed on the surfaces of the two limiting strips 6. The dimensions of the two slots 31 match the dimensions of the extension portions on both sides of the first arc-shaped fixing member 4 and the second arc-shaped fixing member 5. Extension plates 32 are fixedly installed on both sides of the surfaces of the two limiting strips 6. The extension plates 32 on both sides of the limiting strips 6 are staggered vertically. Bolts 33 are threaded onto the surfaces of all four extension plates 32. Two threaded holes 34 matching the bolts 33 are formed on one side of both the first arc-shaped fixing member 4 and the second arc-shaped fixing member 5. The positions of the threaded holes 34 on one side of the first arc-shaped fixing member 4 and the second arc-shaped fixing member 5 are opposite. The thickness of the extension portions of the first arc-shaped fixing member 4 and the second arc-shaped fixing member 5 is 10mm, and the depth of the slots 31 is 12mm, forming an interference fit.

[0027] Working principle: When the device is needed, firstly, snap the first arc-shaped fixing member 4 and the second arc-shaped fixing member 5 onto the upper and lower sides of the insulation layer body 1 respectively, aligning the 10mm thick extensions on both sides of the arc-shaped fixing members with the slots 31 on the surface of the limiting strip 6. Then, insert the limiting strip 6 along the extension, so that the slots 31 and the extension form an interference fit with a depth of 12mm. Next, tighten the four bolts 33 respectively, so that they pass through the extension plate 32 and are screwed into the threaded holes 34 of the first arc-shaped fixing member 4 and the second arc-shaped fixing member 5. Since the extension plate 32 is staggered vertically, the bolts do not interfere with each other during installation, thus completing the clamping and fixing of the insulation layer body 1. When hoisting is required, first rotate the rotating wheel 208 to drive the threaded rod 207 to rotate counterclockwise. Rotating 207 causes the T-shaped plate 210 to move to the left along the slide bar 209, driving the insertion rod 211 to exit from the insertion hole 212 of the rotating shaft 203, releasing the limit on the rotating shaft 203. Then, the lifting ring 205 is rotated out of the storage groove 202 to a vertical state. At this time, the lifting ring 205 is at 90° with the storage groove. Next, the rotating wheel 208 is reversed so that the T-shaped plate 210 drives the insertion rod 211 to insert into the corresponding insertion hole 212 on the rotating shaft 203. Finally, the hook of the external lifting equipment is connected to the lifting ring 205, and the insulation layer body 1 can be lifted. After the lifting is completed, the rotating wheel 208 is rotated counterclockwise to exit the insertion rod 211, and then the lifting ring 205 is rotated and stored in the storage groove 202 so that the lifting ring 205 is flush with the surface of the fixed seat 201. Next, rotate the wheel 208 clockwise to insert the insertion rod 211 into the initial insertion hole 212, and relock the rotating shaft 203 to reduce the space occupied by the device.
