Problems solved by technology

[0002] The water-cooled wall is usually made of steel pipes installed side by side, and there are many welded joints on the water-cooled wall. During the overhaul of the power plant, the welded joints of the water-cooled wall tubes need to be inspected and repaired. Radiographic inspection is an important inspection method. Usually, the source machine is installed In the furnace, the negatives are installed near the area to be inspected outside the furnace. At present, the majority of negatives are installed manually by erecting scaffolding. When there are many parts to be inspected, scaffolds of different heights need to be erected, which will cost more manpower and construction period, and high-altitude operations are more risky
[0003] The commonly used two-degree-of-freedom system is usually composed of synchronous belts or screw rods. It has high requirements on the structure and needs to be customized for different strokes, and it is difficult to achieve a larger stroke

Embodiment 1

[0035] The present invention provides a vertical wall two-degree-of-freedom positioning system with adjustable vertical automaticity, which includes a lateral movement system 100, a vertical movement system 200, and an encoding assembly 300. The vertical movement system 200 is slidably connected to the lateral movement system 100. The encoding component 300 measures the moving positions of the lateral movement system 100 and the vertical movement system 200 respectively. It can be applied to the occasion requirements of different strokes and has strong applicability.

[0036] The lateral movement system 100 includes a gravity block 1, a first flexible traction rope 2, a block pulley 101, a guide rail set 102, a sliding set 103, and a first winch assembly 104; At both ends of the group 102, the sliding group 103 is adapted to slide on the guide rail group 102, the first flexible traction rope 2 passes through and is fixed on the sliding group 103, one end of the first flexible ...

Embodiment 2

[0046] This embodiment 2 is completed on the basis of embodiment 1, which is a preferred embodiment. specific:

[0047] Such as figure 1 As shown, the slide rail 6 and the linear track 12 are arranged in parallel. The mounting block 4 slides on the slide rail 6 through the mounting block roller 5, and the two ends of the slide rail 6 are respectively provided with a first pulley 3 and a second pulley 7. A linear track slider 13 suitable for sliding is provided on the linear track 12, and a third pulley 8 and a fourth pulley 9 are respectively provided at both ends of the linear track 12. The mounting block 4 and the linear track slide block 13 are connected by a guide post 18 perpendicular thereto.

[0048] The third winch 23 is installed on the mounting block 4, and the third winch 23 is driven by the third winch motor 22; drive. Both ends of the second traction soft rope 24 are respectively wound on the second hoist 14 and the third hoist 23 , and the middle of the seco...

Abstract

The invention provides a vertical wall surface two-degree-of-freedom positioning system with adjustable vertical automation degree, which relates to the technical field of in-service inspection and maintenance of power plants, and comprises a transverse moving system, a vertical moving system and a coding assembly, wherein the vertical moving system is connected to the transverse moving system in a sliding mode, and the moving positions of the transverse moving system and the vertical moving system are measured through the coding assembly. The transverse moving system comprises a gravity block, a first traction soft rope, a pulley block, a guide rail group, a sliding group and a first winch assembly,wherein the first traction soft rope is wound or unwound through the first winding assembly, the gravity block drives the first traction soft rope to slide on the pulley block, and the first traction soft rope drives the sliding set to slide on the rail set. The system is high in adaptability, synchronous movement of the mounting block and the linear rail sliding block is achieved, the stroke of the vertical freedom degree can be conveniently adjusted, and the displacement measurement precision is improved.

Description

technical field [0001] The invention relates to the technical field of in-service inspection and maintenance of power plants, in particular to a vertical wall two-degree-of-freedom positioning system with adjustable vertical automaticity.
