Embodiment approach

[0057] Specifically, please also refer to image 3 , Figure 4 and Figure 5, as a specific embodiment of the working shed for maintenance of nuclear power equipment provided by the present invention, each vertical telescopic rod 3 includes an outer sleeve 31, an inner sleeve 32 slidingly arranged in the outer sleeve 31, and an inner sleeve 32 for positioning A positioning mechanism 33 for axially moving the inner sleeve 32 in the outer sleeve 31 . When in use, the inner sleeve 32 moves axially in the outer sleeve 31, and then the positioning mechanism 33 is used to position the axial movement position of the inner sleeve 32 in the outer sleeve 31, so as to conveniently adjust the awning. The height of the body skeleton.

specific Embodiment approach

[0058] Please also refer to Figure 4 , Figure 5 and Figure 6 , as a specific embodiment of the working shed for maintenance of nuclear power equipment provided by the present invention, each positioning mechanism 33 includes an elastic member 331 installed in the inner sleeve 32 and a positioning column 332 with one end supported on the elastic member 331 , the inner sleeve 32 is provided with a through hole 321 for the other end of the corresponding positioning column 332 to extend out of the inner sleeve 32, and the outer sleeve 31 is provided with positioning holes for the positioning column 332 to extend into at intervals along its axial direction. Hole 311.

[0059] In this embodiment, each inner sleeve 32 is provided with a positioning mechanism 33 , and each outer sleeve 31 is sequentially provided with positioning holes 311 that cooperate with corresponding positioning columns 332 to lock the corresponding inner sleeve 32 at intervals along its axial direction.

Abstract

The invention provides an operation shed for nuclear power equipment maintenance, multiple horizontal telescopic rods, multiple vertical telescopic rods and multiple three-way connectors are spliced to form the shed body framework, the multiple pieces of fireproof cloth cover the top face and all the side faces of the shed body framework, and the operation space completely isolated from the outside is formed in the shed body framework. Dust diffusion, spark splashing or molten welding slag splashing during cutting, grinding and welding operation is avoided, erecting of an operation shed is facilitated, and the operation efficiency is improved. The second horizontal splicing heads are rotatably installed on the connecting bases, the horizontal telescopic rods can be spliced into different polygons through the three-way connectors according to needs, then a columnar shed body framework is formed through connection of the vertical telescopic rods, and the erecting shape of the operation shed can be conveniently selected according to field space adaptability. The application of the operation shed in a nuclear power plant is not limited, and the universality is high. The height, the length and the width of the greenhouse body framework can be adjusted in a telescopic mode, rapid disassembly can be achieved, and carrying and turnover use are convenient.

Description

technical field [0001] The invention belongs to the technical field of maintenance of nuclear power plants, and more specifically relates to an operation shed for maintenance of nuclear power equipment. Background technique [0002] Cutting, grinding and welding operations are often involved in the maintenance of nuclear power plants, especially when repairing machinery and equipment on site. Since cutting, grinding and welding operations are all hot operations, protection is generally required according to the requirements of the operation. For example, when cutting, grinding or welding operations are carried out at the site of a nuclear power plant, the fixed scaffolding is usually covered with three-proof cloth, and a temporary protective shed is built to isolate the working area from the outside world, avoiding environmental pollution caused by the spread of dust particles, and preventing Sparks or molten welding slag splash, causing injury to peripheral equipment in th...
