Problems solved by technology

[0003] A disadvantage of the known rotor pivoting system is that its use presupposes at least an industrial peripheral device in the form of an industrially produced base on which a steering stand and at least one support stand are arranged and forces can be transferred between Introduced in the base via the turntable when the rotor is erected
However, since such peripheral devices are not always present, the applicability of the known rotor pivoting systems is limited

Embodiment Construction

[0031] The figures show a rotor pivot system 1 according to an embodiment of the invention for erecting a rotor, for example for erecting a gas turbine rotor 2 . The rotor pivoting system 1 comprises a heavy-duty frame 3 provided with a plurality of supporting feet 4 and 5 which can be moved out vertically, respectively. The support feet 5 can also be moved out horizontally in the direction of the arrow 6 in order to improve the durability of the heavy duty frame 3 if required. The actuation of the support feet 4 and 5 is currently performed hydraulically, wherein of course alternative actuation variants are also conceivable. On a heavy-duty frame 3 , which can be formed, for example, as a steel frame, a plurality of base plates 7 are held, which define a walkable surface. On its end sides, the heavy-duty frame is provided with an end wall 8 whose dimensions are chosen such that it essentially corresponds to the end wall of a standard container, the current ISO 49' container,...

Abstract

A rotor pivoting system (1) for setting a rotor (2) upright, for the purpose of maintenance and / or repair work: a turning pedestal (9) having a pivoting device (10), and at least one bearing pedestal (11) for supporting the rotor when not upright; a heavy-duty stand (3) with a multiplicity of vertically extendable supporting feet (4, 5) which receive the turning pedestal and the bearing pedestal and is transportable and introduces forces occurring when a rotor arranged on the turning pedestal (9) and the bearing pedestal (11) is being set upright, via the supporting feet (4, 5), into a base on which said stand is positioned. Also, a method for carrying out maintenance and / or repair work on a rotor (2) of a machine using a rotor pivoting system (1) according to the invention.

Description

technical field [0001] The invention relates to a rotor pivoting system for erecting a rotor, in particular a gas turbine rotor, for performing maintenance and / or repair work, comprising a steering stand having pivoting means arranged thereon; and at least one Support pedestal. Background technique [0002] Maintenance and / or repair work on the rotor is advantageously performed when it is in a vertical position. In particular, the destacking of gas turbine rotors is considerably simplified in this way. Rotor pivoting systems are used in the prior art for erecting rotors with a high dead weight. It includes a steering stand having pivot means disposed thereon; and at least one support stand. The steering platform and the support platform are established in a first step on the industrial workshop floor and aligned with each other, wherein at least the steering platform is anchored to the workshop floor by means of suitable fastening means. In a further step, the rotor to b...
