Problems solved by technology
[0003] When conventional equipment is inspected by a weld detection robot, it is generally placed accurately according to the position of the weld. However, the distance between the wheel grooves on both sides of the weld of the steam turbine rotor is small, the blade volume is large, and it is difficult for personnel to enter, and the detection robot has a certain weight. It is more difficult to place in the designated position, and in the process of manual placement, personnel are easy to bump, bumping and scratching the blade

The invention discloses a conveying device for a rotor welding joint detecting robot. The conveying device comprises a moving lifting mechanism and a limiting platform mechanism located above the moving lifting mechanism; the moving lifting mechanism comprises a base, a driving component which is arranged on the base and used for driving the limiting platform mechanism to rise and fall as well asa moving component arranged below the base; the limiting platform mechanism comprises a limiting platform, a detecting positioning device and a robot fixing device which are arranged on the limiting platform as well as coarse adjustment limiting components which are arranged on two sides of the limiting platform and used for clamping wheel grooves in two sides of rotor welding joints. According tothe conveying device for the rotor welding joint detecting robot, the rotor welding joint detecting robot is easy and precise to place, and the difficulty and inconvenience caused by manual placementcan be avoided.
Description
technical field [0001] The patent of the present invention relates to the technical field of non-destructive testing of steam turbines in service, and specifically relates to a conveying device for a rotor weld detection robot. Background technique [0002] As one of the important equipment of nuclear power plant, the welded rotor of steam turbine has compact structure and heavy operating load, so the requirements for welding process and flaw detection between rotors are very high. In order to ensure the safety and reliability of the rotor in high-speed operation, regular and efficient in-service inspection of welded joints is very important. Due to the limitation of the size of the steam turbine rotor blades in service, many detection positions cannot be reached during manual conventional ultrasonic detection, and the detection cannot be carried out accurately and efficiently. For the automatic inspection of welded rotors, the original foreign inspection technology mostly ...
