[0067] A first aspect of this application provides a turbine measuring point blade fixing device for fixing a turbine measuring point blade 100 to a turbine disk 200, the turbine disk including a first blade root groove 201 and a second blade root groove 202. Figure 1-3 As shown, in some embodiments, the turbine measuring point blade fixing device includes a support assembly 30, a first pull block 40, a second pull block 50, and a clamping assembly 60.

[0068] The support component 30 is used to abut the lower side of the turbine measuring point blade 100. The first pull block 40 is embedded in the first blade root groove 201. The first end of the first pull block 40 is hooked to the end face of the first blade root groove 201, and the second end of the first pull block 40 is connected to the support component 30.

[0069] The second pull block 50 is embedded in the second leaf root groove 202. The first end of the second pull block 50 is hooked to the end face of the second leaf root groove 202, and the second end of the second pull block 50 is connected to the support component 30.

[0070] Specifically, such as Figure 1 As shown, the second end of the first pull block 40 is connected to the first side of the support assembly 30; for example, the second end of the first pull block 40 can be detachably connected to the first side of the support assembly 30 by bolts, facilitating the disassembly and installation of the first pull block 40 and the support assembly 30. The second end of the second pull block 50 is connected to the second side of the support assembly 30; for example, the second end of the second pull block 50 can be detachably connected to the second side of the support assembly 30 by bolts, facilitating the disassembly and installation of the second pull block 50 and the support assembly 30.

[0071] In the embodiments of this application, such as Figure 2 and 3 As shown, the support assembly 30 is used to abut against the lower side of the turbine measuring point blade 100 to support the turbine measuring point blade 100 and prevent it from falling.

[0072] For example, such as Figure 2 and 3 As shown, three turbine measuring blades 100 need to be installed on the turbine disk 200. The first pull block 40 can be embedded in the first blade root groove 201, and then the first end of the first pull block 40 is hooked to the end face of the first blade root groove 201, and the second end of the first pull block 40 is connected to the support component 30. Correspondingly, the second pull block 50 is embedded in the second blade root groove 202, and the first end of the second pull block 50 is hooked to the end face of the second blade root groove 202, and the second end of the second pull block 50 is connected to the support component 30. Then, three turbine measuring blades 100 are installed in the three blade root grooves between the first blade root groove 201 and the second blade root groove 202.

[0073] Since the first end of the first pull block 40 is hooked to the end face of the first blade root groove 201, the first end of the second pull block 50 is hooked to the end face of the second blade root groove 202, and the first end of the first pull block 40 and the second end of the second pull block 50 are respectively connected to the first and second sides of the support assembly 30, the support assembly 30 provides good support and fixation for the three turbine measuring blades 100, and can prevent the turbine measuring blades 100 from falling off during the rotation of the turbine wheel 200.

[0074] In this embodiment, the support component 30, the first pull block 40, and the second pull block 50 are made of rigid materials; for example, the support component 30, the first pull block 40, and the second pull block 50 can be made of stainless steel, which can meet the requirements for supporting and fixing the turbine measuring point blade 100.

[0075] The first aspect of this application provides a turbine measuring point blade fixing device, including a support component 30 for abutting the lower side of the turbine measuring point blade 100, a first pull block 40 embedded in a first blade root groove 201, and a second pull block 50 embedded in a second blade root groove 202. By hooking the first end of the first pull block 40 to the end face of the first blade root groove 201 and connecting its second end to the support component 30, and by hooking the first end of the second pull block 50 to the end face of the second blade root groove 202 and connecting its second end to the support component 30, the device can provide good support and fixing for the turbine measuring point blade 100 when it is installed on the turbine wheel 200, effectively solving the problem of the turbine measuring point blade 100 falling off during the rotation of the turbine wheel 200.

[0076] like Figure 1 As shown, in order to enable the first end of the first pull block 40 and the first end of the second pull block 50 to be stably hooked onto the end face of the first leaf root groove 201 and the end face of the second leaf root groove 202 respectively, a first hooking part 41 is provided at the first end of the first pull block 40 and extends toward the end face of the first leaf root groove 201, and a second hooking part 51 is provided at the first end of the second pull block 50 and extends toward the end face of the second leaf root groove 202.

[0077] like Figure 1 As shown, in some embodiments, the support assembly 30 includes a support plate 31 and a first fastener 32. The first fastener 32 is screwed to the support plate 31. The support plate 31 is connected to the second end of the first pull block 40 and the second end of the second pull block 50. The first fastener 32 is used to abut against the lower side of the turbine measuring blade 100. The support plate 31 can be detachably connected to the second end of the first pull block 40 and the second end of the second pull block 50 respectively by bolts for disassembly and installation. By setting the first fastener 32, the turbine measuring blade 100 can be pressed upward, which can prevent the turbine measuring blade 100 from moving during the flipping process.

[0078] Based on the actual circumferential curved surface structure design of the turbine disk 200, in some embodiments, the support plate 31 has an arc-shaped structure, with the first pull block 40 inclinedly disposed on the arc-shaped support plate 31 and the second pull block 50 inclinedly disposed on the arc-shaped support plate 31. By designing the support plate 31 as arc-shaped, the support plate 31 can be adapted to different turbine disk 200 structures.

[0079] like Figure 2 and 3 As shown, in some embodiments, the number of turbine measuring blades 100 and the number of first fasteners 32 are each three, with each first fastener 32 corresponding to one turbine measuring blade 100. It is understood that when a larger number of turbine measuring blades 100 need to be installed, an appropriate length of the support assembly 30 can be set to meet the support function for the larger number of turbine measuring blades 100.

[0080] like Figure 1 As shown, to prevent the turbine measuring blade 100 from moving during the rotation of the turbine disk 200, in some embodiments, the turbine measuring blade fixing device further includes a clamping component 60. The clamping component 60 includes a clamping plate 61 and a second fastener 62. The second fastener 62 and the clamping plate 61 are screwed together. The clamping plate 61 is connected to the first end of the first pull block 40 and the first end of the second pull block 50. The second fastener 62 is used to abut against the upper side of the turbine measuring blade 100. The clamping plate 61 can be detachably connected to the first end of the first pull block 40 and the first end of the second pull block 50 by bolts, which facilitates the installation and removal of the clamping plate 61 from the first end of the first pull block 40 and the first end of the second pull block 50. By setting the second fastener 62, the turbine measuring blade 100 can be clamped downwards, and in cooperation with the first fastener 32 in the aforementioned embodiment, the positional movement of the turbine measuring blade 100 during the rotation can be effectively prevented.

[0081] like Figure 2 and 3 As shown, in some embodiments, the number of turbine measuring blades 100 and the number of second fasteners 62 are each three, with each second fastener 62 corresponding to one turbine measuring blade 100. It is understood that when a larger number of turbine measuring blades 100 need to be installed, an appropriate length of the second fastener 62 can be set to meet the clamping effect on the larger number of turbine measuring blades 100.

[0082] Based on the same inventive concept, a second aspect of this application provides a turbine measuring point blade fixing device for fixing a turbine measuring point blade 100 to a turbine disk 200, the turbine disk including a first blade root groove 201 and a second blade root groove 202. Figure 4-8As shown, in some embodiments, the turbine measuring point blade fixing device includes a support 70, a first locking block assembly 81, and a second locking block assembly 82.

[0084] The second locking component 82 is locked in the second leaf root groove 202. The first end of the second locking component 82 is hooked to the end face of the second leaf root groove 202, and the second end of the second locking component 82 is connected to the support member 70.

[0085] Specifically, such as Figure 1 and 7 As shown, the support member 70 is used to support and fix the turbine measuring blade 100. The second end of the first locking block assembly 81 can be detachably connected to the first side of the support member 70 via bolts, facilitating the disassembly and installation of the first locking block assembly 81 and the support member 70. The second end of the second locking block assembly 82 can be detachably connected to the second side of the support member 70 via bolts, facilitating the disassembly and installation of the second locking block assembly and the support member 70. By locking the first locking block assembly 81 and the second locking block assembly 82 into the first blade root groove 201 and the second blade root groove 202 respectively, and hooking the first end of the first locking block assembly 81 and the first end of the second locking block assembly 82 to the end faces of the first blade root groove 201 and the second blade root groove 202 respectively, the support member 70 can provide good support and fixation for the turbine measuring blade 100.

[0086] In this embodiment, the support member 70, the first locking block assembly 81, and the second locking block assembly 82 are made of rigid materials; for example, the support member 70, the first locking block assembly 81, and the second locking block assembly 82 can be made of stainless steel, which can meet the requirements for supporting and fixing the turbine measuring point blade 100.

[0087] The second aspect of this application provides a turbine measuring point blade fixing device, including a support member 70 for supporting the turbine measuring point blade 100, a first locking block assembly 81 locked in a first blade root groove 201, and a second locking block assembly 82 locked in a second blade root groove 202. By hooking the first end of the first locking block assembly 81 to the end face of the first blade root groove 201 and connecting its second end to the support member 70, and by hooking the first end of the second locking block assembly 82 to the end face of the second blade root groove 802 and connecting its second end to the support member 70, the device can provide good support and fixing for the turbine measuring point blade 100 when it is installed, and can effectively prevent the turbine measuring point blade 100 from falling off during the rotation of the turbine wheel 200.

[0088] like Figure 4-8 As shown, in order to enable the first end of the first locking block assembly 81 and the first end of the second locking block assembly 82 to be stably hooked onto the end face of the first leaf root groove 201 and the end face of the second leaf root groove 202 respectively, a hooking member is provided at the first end of the first locking block assembly 81 and extends toward the end face of the first leaf root groove 201, and a second hooking member is provided at the first end of the second locking block assembly 82 and extends toward the end face of the second leaf root groove 202.

[0089] like Figure 4 and 5 As shown, in some embodiments, the first locking block assembly 81 includes a third pull block 811 and a first plug block 812. The second end of the third pull block 811 is connected to the support member 70, and the first end of the third pull block 811 is hooked onto the end face of the first blade root groove 201. The first plug block 812 is used to lock the third pull block 811 into the first blade root groove 201. The second end of the third pull block 811 can be detachably connected to the first side of the support member 70 by bolts, which facilitates the disassembly and installation between the third pull block 811 and the support member 70. By setting the first plug block 812, the third pull block 811 can be locked into the first blade root groove 201, and the third hooking part 8111 provided on the first end of the third pull block 811 is hooked onto the end face of the first blade root groove 201, which enables the support member 70 to provide good support and fixation for the turbine measuring point blade 100.

[0090] like Figure 5 As shown, in some embodiments, the first locking block assembly 81 further includes a fifth pulling block 813. The first end of the fifth pulling block 813 is hooked onto the end face of the first leaf root groove 201, and the second end of the fifth pulling block 813 is detachably connected by bolts and a support member 70. The first end of the fifth pulling block 813 is also provided with a fourth hooking portion 8131 extending towards the end face of the first leaf root groove 201, which allows the fifth pulling block 813 to be stably hooked onto the end face of the first leaf root groove 201. A first plug block 812 is engaged between the third pulling block 811 and the fifth pulling block 813 to secure the third pulling block 811 and the fifth pulling block 813 in the first leaf root groove 201, preventing the hooking contact between the third pulling block 811 and the fifth pulling block 813 and the end face of the first leaf root groove 201 from loosening.

[0091] During installation, such as Figure 7As shown, the third pull block 811 and the fifth pull block 813 are first inserted into both sides of the first leaf root groove 201, and the third hook part 8111 on the first end of the third pull block 811 and the fourth hook part 8131 on the first end of the fifth pull block 813 are hooked to the end faces on both sides of the first leaf root groove 201, respectively. Then, the first plug 812 is inserted between the third pull block 811 and the fifth pull block 813, so that the third pull block 811 and the fifth pull block 813 are stably hooked to the end faces of the first leaf root groove 201, respectively. The support member 70 is fixed to the second end of the third pull block 811 and the second end of the fifth pull block 813 by fixing screws. Finally, insert the turbine measuring blade 100 into the other blade root grooves between the first blade root groove 201 and the second blade root groove 202. After the turbine disk 200 is stacked on the rotor and the rotor is flipped to a horizontal state, first loosen the fixing screws and remove the support 70. Then, use the pin puller to remove the first plug 812 and disassemble the third pull block 811 and the fifth pull block 813.

[0092] like Figure 4 and 6 As shown, in some embodiments, the second locking block assembly 82 includes a fourth pull block 821 and a second plug block 822. The second end of the fourth pull block 821 is connected to the support member 70, and the first end of the fourth pull block 821 is hooked onto the end face of the second leaf root groove 202. The second plug block 822 is used to lock the fourth pull block 821 into the second leaf root groove 202. The second end of the fourth pull block 821 can be detachably connected to the second side of the support member 70 by bolts, facilitating the disassembly and installation of the fourth pull block 821 and the support member 70.

[0093] By setting the second stopper 822, the fourth pull block 821 can be locked in the second blade root groove 202, and the fifth hook part 8211 set on the first end of the fourth pull block 821 can be hooked to the end face of the second blade root groove 202, so that the support member 70 can play a good supporting and fixing role for the turbine measuring point blade 100.

[0094] like Figure 6 As shown, in some embodiments, the second locking block assembly 82 further includes a sixth pulling block 823. The first end of the sixth pulling block 823 is hooked onto the end face of the second leaf root groove 202, and the second end of the sixth pulling block 823 is detachably connected by bolts and a support member 70. The first end of the sixth pulling block 823 is also provided with a sixth hooking portion 8231 extending towards the end face of the second leaf root groove 202, which allows the sixth pulling block 823 to be stably hooked onto the end face of the second leaf root groove 202. The second plug 822 is engaged between the fourth pulling block 821 and the sixth pulling block 823 to secure the fourth pulling block 821 and the sixth pulling block 823 in the second leaf root groove 202, preventing the hooking contact between the fourth pulling block 821 and the sixth pulling block 823 and the end face of the second leaf root groove 202 from loosening.

[0095] During installation, such as Figure 7 As shown, firstly, the fourth pull block 821 and the sixth pull block 823 are inserted into both sides of the second leaf root groove 202, and the fifth hook part 8211 on the first end of the fourth pull block 821 and the sixth hook part 8231 on the first end of the sixth pull block 823 are hooked to the end faces on both sides of the second leaf root groove 202, respectively.
