Description
Technical Field
The utility model belongs to the field of gas turbine assembly, and particularly relates to an interference pin dismounting device.
Background
Interference pins at the positions of the combustion chamber shell, the turbine secondary guide and the like have theoretical interference sizes of 0.015-0.025 mm, but most interference pins become difficult to disassemble after the gas turbine works in a severe environment for a long time. The interference pin dismounting device is a necessary tool for ensuring smooth dismounting of the interference pin.
Disclosure of Invention
The utility model aims to provide an interference pin dismounting device capable of replacing different types of specially-made pullouts to dismount interference pins with various sizes.
An interference pin dismounting device comprises a pulling head, a nut, a rod and a heavy hammer; the rod is sleeved into the heavy hammer; the nut and the pulling head are connected to the rod through threads; the pullout head is mounted on the interference pin.
Further, the pulling head is replaceable, and according to the interference pin heads with various different sizes, the interference pins with various sizes are detached by replacing the pulling heads with different types.
The utility model has the beneficial effects that: the utility model can solve the problem of disassembly of interference pins at the positions of the combustion chamber shell, the turbine secondary guide and the like, if the head is damaged, the new head can be replaced in time, the rest main bodies can be used continuously, the working hours and the production cost are saved, and different types of specially-made heads can be replaced freely to disassemble the interference pins with various sizes.
