Device for installing and removing a component on a gas turbine

An arrangement, comprising:

• a casing comprising:
• a mating flange configured to secure a component;
• at least two mating guide sections which are disposed radially outside of the mating flange;
• and a mating connection section disposed radially outside of the mating flange;
• wherein each mating guide section comprises a guide body that is immovably integral to the casing and that protrudes from the casing, and wherein each mating connection section comprises a connection body that is immovably integral to the casing and that protrudes from the casing, and wherein the guide body and the connection body are immovable relative to each other;
• a rail system on which a runner s displaceable along a predefined displacement axis;
• a terminal positioning part which is securely connected to the rail system, the terminal positioning part comprises:
• at least two guide sections, each of which is designed to mechanically cooperate with a respective mating guide section of the at least two mating guide sections;
• and at least one connection section designed to establish a secure yet releasable connection with a respective mating connection section;
• wherein the terminal positioning part is designed as a connection plate comprising two planar sections each in a form of a projection, each projection comprising a respective guide section of the at least two guide sections;
• wherein the connection plate is immovably secured directly to the connection body but not secured directly to the mating flange, and the at least two guide sections and the at least one connection section are configured to be positioned radially outside of the mating flange;
• wherein each respective guide section mechanically cooperates with each respective mating guide section via a respective guide arrangement, wherein each respective guide arrangement comprises a bore and a stud that slides into the bore via axial movement alone and in a fit that properly aligns the component on the casing before the connection plate is secured to directly the connection body, and wherein each respective guide section comprises either the stud the bore, and
• wherein for each mating guide section when the respective guide section comprises the bore the mating guide section comprises the stud, and when the respective guide section comprises the stud the mating guide section comprises the bore.

A mounting arrangement, comprising:

• a gas turbine engine combustion section outer casing comprising a burner mount comprising a burner flange surrounding a burner opening through the combustion section outer casing, the burner flange configured to secure a burner to the burner mount;
• a connection body protruding from and immovable relative to the combustion section outer casing and disposed adjacent and radially outside the burner flange with respect to the burner opening;
• a mounting device comprising:
• a rail system comprising rails on which a runner translates, the runner configured to secure the burner to the rails;
• and a connection plate connected to the rails;
• and
• a pattern of unthreaded alignment pins configured to align with a matching pattern of alignment bores only when the mounting device is positioned in a predetermined orientation relative to the burner mount, wherein once aligned alignment pins of the pattern of unthreaded alignment pins are advanced into alignment bores of the matching pattern of alignment bores via axial movement alone until the connection plate abuts the connection body, thereby enabling the connection plate to be immovably secured directly to the connection body, not secured directly to the burner flange, and positioned radially outside the burner flange when so secured.
