Description

Technical Field

[0001] The present invention belongs to the field of gas turbine machinery, and particularly relates to a tooling for disassembling and assembling the lubricating oil assembly of a gas turbine. Background Art

[0002] The lubricating oil assembly of a gas turbine is an important component that ensures lubrication and cooling of bearing components and the gear meshing parts of the engine under all operating conditions of the engine, and mainly plays the role of supplying lubricating oil to the gas turbine and returning oil. Due to the limited space of the box where the gas turbine is located, once the lubricating oil assembly fails or needs maintenance, disassembly or reinstallation is extremely difficult. The lubricating oil assembly is located on the air intake side of the gas turbine, where the space is even narrower and the mass is relatively large. It is impossible to complete the replacement by manpower alone. If the traditional scheme is used for disassembly and assembly, the top plate and side wall plate of the box body need to be disassembled each time, and the lubricating oil assembly is lifted by the sling in the cabin for installation and disassembly. This not only takes time and effort, but also is difficult to accurately align with the connection part of the gas turbine. At the same time, it is required that there is a fixed position for the sling and lifting tool in the cabin, which has high requirements for the external system. Multiple toolings need to be used in cooperation, and often the toolings need to be reprocessed or produced on site during disassembly and assembly, which increases the difficulty of disassembly and assembly and wastes a lot of manpower and material resources. Therefore, in order to ensure the safety and reliability of the disassembly and assembly process of the lubricating oil assembly on the gas turbine and save manpower and material resources, it is particularly important to design a tooling with a simple structure and an integrated adjustable type.

[0018] The present invention will be further described below with reference to the drawings.

[0019] As Figures 1-6As shown in the figure, a tooling for disassembling and assembling the lubricating oil assembly of a gas turbine includes a roller assembly 1, a hanger assembly 2, a semi-circular assembly 3, and a connection assembly 4. The hanger assembly 2 is installed on the flange of the intake connection short pipe of the gas turbine. The roller assembly 1 is installed on the hanger assembly 2 and can move on the hanger assembly 2 to be adjusted to a suitable position for connection with the lubricating oil assembly. The semi-circular assembly 3 is connected to the roller assembly 1. The connection assembly 4 is connected to the semi-circular assembly 3.

[0020] During disassembly, disconnect the lubricating oil assembly from the gas turbine, and use manpower and a chain hoist to move the lubricating oil assembly along the hanger assembly 2 out from the lower part of the gas turbine to the edge of the gas turbine chassis. Install the process support on the cross beam of the gas turbine chassis. Remove the lubricating oil assembly from the connection assembly 4 and transport it to the disassembly and storage site.

[0021] During installation, install the process support on the cross beam of the gas turbine chassis, place the lubricating oil assembly to be replaced on the support, and fix it to the lubricating oil assembly through the connection assembly on the tooling. Use manpower and a chain hoist to move the lubricating oil assembly along the hanger assembly towards the lower part of the gas turbine to a suitable position for reinstallation.

[0022] The roller assembly 1 includes a roller 1A, a shaft 11B, a shaft 21C, a shaft 31D, a bushing 1E, and a lifting ring 1F. The roller 1A and the lifting ring 1F are fixed by the shaft 11B and a slotted nut. The two lifting rings 1F are fixed by the shaft 11B and a nut. The shaft 31D is fixedly connected to the lifting ring 1F through a nut and the bushing 1E.

[0023] The hanger assembly 2 includes a stop angle 2A, an upper assembly 2B, and a lower assembly 2C. The stop angle 2A is installed on the upper assembly 2B. The upper assembly 2B enables the lubricating oil assembly to move within a certain space. The upper assembly 2B is connected to the lower assembly 2C, and the lower assembly 2C fixes the tooling to the gas turbine casing.

After the connection fasteners 14B and the connection fasteners 24C are fixed to the lubricating oil assembly, fix the plate assembly 4A with nuts. Unscrew the connection bolts of the stop angle 2A and the upper assembly 2B, and remove the stop angle 2A from the upper assembly 2B. Install the roller assembly 1 onto the upper assembly 2B. When disassembling, the roller moves towards the intake connection stub pipe, and when reinstalling, the roller moves towards the storage position of the lubricating oil assembly. Finally, fix the stop angle 2A to the upper assembly 2B with bolts again. When disassembling: Unscrew the fasteners of the housing flange of the lubricating oil assembly and the lower transmission case. Move the lubricating oil assembly from the lower transmission case towards the edge of the gas turbine chassis along the upper assembly 2B of the tooling. Install the process support onto the crossbeam of the gas turbine chassis, remove the lubricating oil assembly from the tooling and transport it to the disassembly and storage site. Remove the connection fasteners 14B and the connection fasteners 24C from the flange of the lubricating oil assembly.
