[0025] Combine the following Figure 1 and Figure 2 The technical solution provided by the utility model is described in more detail.

[0026] like Figure 1 and Figure 2As shown, the utility model provides a special tool for reinstalling the thrust plate gland of a PDH gas turbine, comprising a connecting portion, a fixing bracket 1, a guide rail 2 and a balancing block 3, wherein: one end of the connecting portion is fixedly connected to the fixing bracket 1, and the other end is used for detachable connection with the thrust plate; the side of the fixing bracket 1 away from the connecting portion is fixedly connected to the guide rail 2, and the balancing block 3 is movably arranged along the guide rail 2 and can be locked on the guide rail 2; when the fixing bracket 1 is hoisted, the balancing block 3 is used to keep the thrust plate lifted in a balanced manner.

[0027] The special tool for reinstalling the thrust plate gland of the PDH gas turbine of this embodiment uses a crane to lift the fixed bracket 1, push the balancing block 3, and move the balancing block 3 on the guide rail 2, so that the thrust plate gland 7 and the balancing block 3 are at the same horizontal position, and then the balancing block 3 is locked on the guide rail 2 to prevent the balancing block 3 from sliding off. The thrust plate gland 7 can be accurately installed in the gas turbine casing by the manual hand tool, which improves the convenience of reinstalling the thrust plate gland 7 and reduces the labor intensity.

[0028] Among them, see Figure 1 As shown, the connecting portion includes a connecting rod 5 , and the connecting rod 5 is welded to the fixing bracket 1 .

[0029] As an alternative embodiment, see Figure 1 and Figure 2 As shown, an axial hole 301 is provided on the balancing block 3. The axial hole 301 is located on the central axis of the balancing block 3 and passes through both ends of the balancing block 3. The guide rail 2 passes through the axial hole 301. The balancing block 3 can slide along the guide rail 2 under the action of external force.

[0030] The diameter of the shaft hole 301 is larger than the outer diameter of the guide rail 2, and the balancing block 3 can be sleeved on the guide rail 2 and move along the length direction of the guide rail 2. When the balancing block 3 and the thrust plate gland 7 are at the same horizontal position, the balancing block 3 can be locked. The balancing block 3 facilitates the thrust plate gland 7 to remain horizontal during the hoisting and installation process.

[0031] See also Figure 1 As shown, the guide rail 2 is a rod structure.

[0032] As an alternative embodiment, see Figure 1 and Figure 2 As shown, a locking hole 302 is provided on the balancing weight 3, and the locking hole 302 is communicated with the shaft hole 301. A locking member 4 is threadedly connected to the locking hole 302, and the locking member 4 is used to abut against the guide rail 2, so as to lock the balancing weight 3 on the guide rail 2.

[0033] The locking member 4 can be a structure such as a bolt, a screw or a threaded pin. The locking member 4 is threadedly connected to the balancing block 3. When the locking member 4 is turned, when the end of the locking member 4 abuts against the guide rail 2, the balancing block 3 can be locked at a specific position on the guide rail 2 to prevent the balancing block 3 from sliding off the guide rail 2 during the lifting and reinstallation of the thrust plate cover 7.

[0034] As an alternative embodiment, see Figure 1 As shown, the connecting rod 5 is arranged parallel to the guide rail 2, the connecting rod 5 is fixedly connected to the fixed bracket 1, and the other end is detachably connected to the thrust plate.

[0035] The connecting rod 5 and the guide rail 2 are located on opposite sides of the fixed bracket 1 and at the upper and lower ends of the fixed bracket 1. The above-mentioned layout structure of the connecting rod 5 and the guide rail 2 facilitates the balancing block 3 to remain level with the thrust plate gland 7, and facilitates the lifting and installation of the thrust plate gland 7.

[0036] As an alternative embodiment, see Figure 1 As shown, the connection portion further includes a connection plate 8, the connection plate 8 is welded to the connection rod 5, and the connection plate 8 is detachably connected to the end surface of the thrust plate via a locking piece.

[0037] The above-mentioned locking elements may be bolts. The connecting plate 8 is an arc-shaped plate that matches the profile of the thrust plate gland 7. When the thrust plate gland 7 is installed, the connecting plate 8 is connected to the thrust plate gland 7 through locking elements (bolts, etc.). After the thrust plate gland 7 is installed, an auxiliary wrench is used to reach into the casing of the gas turbine to disassemble the connecting plate 8 and the thrust plate gland 7.

[0038] As an alternative embodiment, see Figure 1 As shown, the radial cross section of the connecting rod 5 is circular, the radial cross section of the shaft hole 301 is circular, and the diameter of the shaft hole 301 is larger than the outer diameter of the connecting rod 5 .

[0039] The above structure facilitates the balancing weight 3 to slide along the guide rail 2 under the action of external force.

[0040] As an alternative embodiment, see Figure 1 As shown, the fixing bracket 1 is provided with a lifting lug.

[0041] The fixed bracket 1 can be lifted to a certain height by a crane through a chain or a traction rope passing through the hanging ear 6. The above structure facilitates the lifting of the fixed bracket 1, thereby facilitating the reinstallation of the thrust plate gland 7.

[0042] As an alternative embodiment, see Figure 1 As shown, the fixing bracket 1 is provided with a weight-reducing hole 11 or a weight-reducing groove, so as to strengthen the deadweight of the fixing bracket 1 and facilitate the transportation and lifting of the tool.
