Description

Technical Field

[0001] This application relates to the field of large cylindrical and shell structure flipping technology, and in particular to a flipping tooling for a combustion chamber intake support assembly. Background Technology

[0002] During the assembly and disassembly of a gas turbine, it is necessary to flip the combustion chamber and intake chamber supports from a vertical position to a horizontal position or vice versa.

[0003] Existing methods for flipping combustion chambers and intake chamber supports typically involve using lifting lugs on the combustion chamber to flip them. This method has several serious drawbacks: Firstly, it poses significant safety hazards. The lifting lugs, originally designed for lifting the combustion chamber shell, are now used to lift the combustion chamber shell and its internal components, as well as the intake chamber support and its internal components. This greatly increases the lifting weight, and the lugs may break during the lifting process, leading to a safety accident. Secondly, it makes assembly difficult. The lifting lugs are located approximately at the center of gravity of the combustion chamber shell, while the center of gravity of the assembled combustion chamber and intake chamber support is far from the location of the lifting lugs. This causes one side of the intake chamber support to tilt severely during lifting, hindering subsequent assembly.

[0004] To address this, we propose a tooling for flipping the combustion chamber intake support assembly. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a combustion chamber intake support assembly flipping fixture. The lifting position of the flipping fixture is close to the center of gravity of the combustion chamber assembly and the intake support assembly. Moreover, the strength of the flipping fixture is much greater than the strength of the lifting lugs of the combustion chamber assembly, ensuring safety and stability during the lifting process. Furthermore, the base plate is locked with the original bolts, making disassembly and assembly convenient and quick, thus improving assembly efficiency.

[0006] The technical solution adopted in this application is as follows: A combustion chamber intake chamber support assembly flipping fixture includes: The base plate has a first support plate and a second support plate spaced apart on one side of the top of the base plate, and a plurality of first through holes spaced apart on the other side of the top of the base plate. The first through holes correspond to the through holes at the connection between the combustion chamber assembly and the intake chamber bracket assembly. The thickness of the base plate is the same as the thickness of the heightening washer at the connection between the combustion chamber assembly and the intake chamber support assembly; the first support plate is provided with a second through hole, and the second support plate is provided with a third through hole corresponding to the second through hole; a pulley is provided between the first support plate and the second support plate, and a hexagonal head bolt passes through the second through hole, the pulley, and the third through hole in sequence, and then connects with a hexagonal head nut; When installing the flipping fixture, remove part of the heightening washer at the connection between the combustion chamber assembly and the intake chamber bracket assembly. Place the first through hole side of the base plate at the position where the heightening washer was removed, and fix the base plate with the fasteners at the connection between the combustion chamber assembly and the intake chamber bracket assembly.

[0007] Its further features are: A reinforcing plate is provided at the bottom of the base plate to increase its strength.

[0008] The bottom plate has an arc shape that is recessed towards the first support plate on the side near the first through hole.

[0009] The first support plate and the second support plate are arranged in parallel.

[0010] The tail end of the hexagonal head bolt is provided with a through hole. After the hexagonal head bolt and the hexagonal head nut are connected, a cotter pin is provided in the through hole of the hexagonal head bolt.

[0011] The hexagonal head nut has a slot.

[0012] Two flipping fixtures are provided at the connection between the combustion chamber assembly and the intake chamber support assembly, and the two flipping fixtures are arranged symmetrically.

[0013] The beneficial effects of this application are as follows: This application features a compact and reasonable structure, and is easy to operate. The lifting straps on both sides pass through pulleys on the two base plates, suspending the tilting fixture, combustion chamber assembly, and intake chamber support assembly. The combustion chamber assembly and intake chamber support assembly are then tilted. The tilting fixture is positioned close to the center of gravity of the combustion chamber assembly and intake chamber support assembly, and its strength is significantly greater than the lifting lugs of the combustion chamber assembly, ensuring safety and stability during the lifting process. Furthermore, the base plates are secured with the original bolts, making disassembly and assembly quick and easy, thus improving assembly efficiency.

[0014] In addition, this application also has the following advantages: (1) Remove some of the bolts connecting the combustion chamber assembly and the intake chamber support assembly, remove the heightening washer, place one side of the base plate with the first through hole at the position where the heightening washer was removed, and then fix the base plate by removing the bolts connecting the combustion chamber assembly and the intake chamber support assembly. Fix the base plate on the other side of the connection between the combustion chamber assembly and the intake chamber support assembly in the same way, with the two base plates set symmetrically. The base plates are locked with the original bolts, making disassembly and assembly convenient and quick. Attached Figure Description

[0022] like Figures 1-5 As shown, a combustion chamber intake chamber support assembly flipping fixture includes a base plate 2, a first support plate 3, a second support plate 4, hexagonal head bolts 5, hexagonal head nuts 6, and pulleys 7.

[0023] The thickness of the base plate 2 is the same as the thickness of the heightening washer 9 at the connection between the combustion chamber assembly 1 and the intake chamber support assembly 8.

[0024] A first support plate 3 and a second support plate 4 are provided at intervals on one side of the top of the base plate 2. A second through hole 301 is provided on the first support plate 3, and a third through hole 401 corresponding to the second through hole 301 is provided on the second support plate 4. A pulley 7 is located between the first support plate 3 and the second support plate 4. A hexagonal head bolt 5 passes through the second through hole 301, the pulley 7, and the third through hole 401 in sequence, and then connects with a hexagonal head nut 6.

[0025] A washer is provided between the hexagonal head bolt 5 and the first support plate 3.

[0026] The first support plate 3 and the second support plate 4 are both fixedly connected to the base plate 2.

[0027] In one embodiment, the first support plate 3 and the second support plate 4 are arranged in parallel.

[0028] Multiple first through holes 201 are provided on the side of the base plate 2 away from the first support plate 3 and the second support plate 4. The multiple first through holes 201 are spaced apart and correspond to the through holes at the connection between the combustion chamber assembly 1 and the intake chamber bracket assembly 8.

[0029] In one embodiment, a reinforcing plate is provided at the bottom of the base plate 2 to improve the rigidity of the base plate 2.

[0030] There can be two reinforcement plates, or other possible numbers.

[0031] In one embodiment, the base plate 2 is provided with an arc shape that is recessed towards the first support plate 3 on the side near the first through hole 201, which can reduce the space occupied by the base plate 2 and improve its applicability.

[0032] In one embodiment, the tail end of the hexagonal head bolt 5 is provided with a through hole. After the hexagonal head bolt 5 and the hexagonal head nut 6 are connected, a cotter pin is provided in the through hole of the hexagonal head bolt 5, which can play a role in preventing loosening and preventing accidents.

[0033] In one embodiment, the hexagonal head nut 6 is provided with a slot.

[0034] In practical use, remove some of the bolts connecting the combustion chamber assembly 1 and the intake chamber support assembly 8, remove the heightening washer 9, place one side of the base plate 2 with the first through hole 201 in the position where the heightening washer 9 has been removed, and then fix the base plate 2 by removing the bolts connecting the combustion chamber assembly 1 and the intake chamber support assembly 8. Fix the base plate 2 on the other side of the connection between the combustion chamber assembly 1 and the intake chamber support assembly 8 in the same manner, with the two base plates 2 arranged symmetrically. The base plates 2 are locked using the original bolts, making disassembly and assembly convenient and quick.

[0035] The lifting straps on both sides pass through pulleys 7 on the two base plates 2, and lift the tilting fixture, combustion chamber assembly 1, and intake chamber support assembly 8 using the lifting straps. Then, the combustion chamber assembly 1 and intake chamber support assembly 8 are tilted. The lifting position of the tilting fixture is close to the center of gravity of the combustion chamber assembly 1 and intake chamber support assembly 8, and the strength of the tilting fixture is much greater than the strength of the lifting lugs of the combustion chamber assembly 1, ensuring safety and stability during the lifting process. In addition, the base plates 2 are locked with the original bolts, which makes disassembly and assembly convenient and quick, improving assembly efficiency.
