Embodiment Construction

[0063] Below, refer to Figure 1 to Figure 19 , the embodiments according to the present invention will be described.

[0064] First, an inspection object to be inspected in the inspection method S1 using the inspection device 5 will be described. The object to be inspected in this embodiment is the turbine 3 of the gas turbine 1 .

[0065] like figure 1 As shown, a gas turbine 1 includes: a compressor 2 that generates high-pressure air; a turbine 3 that is driven by combustion gas; and a plurality of combustors 4 that generate combustion gas by mixing fuel with high-pressure air and then supply it to the turbine 3 .

[0066] The turbine 3 includes: a turbine rotor 31 that rotates around the axis O1; and a turbine housing 35 that covers the turbine rotor 31 from the outer peripheral side. The turbine rotor 31 has a columnar shape extending along the axis O1. On the outer peripheral surface of the turbine rotor 31, a plurality of turbine rotor blade layers 32 arranged at i...

Abstract

The invention provides an inspection tube drive control device. This inspection tube drive control device is provided with: an inverse analysis unit (83) which performs an analysis to move a flexible tube along a predetermined route within an object being inspected, from a start point to a target point of the route; and a forward analysis unit (84) which, on the basis of analysis results from the inverse analysis unit (83), acquires, as analysis operating amounts, operating amounts for an attitude actuator capable of adjusting the attitude of the tube when the tube is positioned at each position on the route, and an advancing and retreating actuator which causes the tube to advance and retreat.

Description

technical field [0001] The present invention relates to a drive control device for an inspection tube, an inspection device, an inspection method, a program for the inspection device, and a guide jig. [0002] This application claims priority to Japanese Patent Application No. 2018-205303 filed on October 31, 2018, and uses the contents thereof here. Background technique [0003] In a rotating machine such as a steam turbine or a gas turbine, it is necessary to periodically inspect the interior of the casing. When such a periodic inspection is performed, a lot of time is required for inspection work if the case is removed and the inside is opened. Therefore, there is a need for a method of inspecting the interior without opening the case. [0004] Specifically, for example, Patent Document 1 describes an inspection device capable of inspecting the inside of a turbine by inserting an insertion portion from the upstream side of a combustor through a transition piece into the...
