Problems solved by technology

The traditional construction method is mainly to weld the lugs on the cladding components, and use the crane in the factory building to carry out the hoisting construction of the stainless steel cladding. The disadvantages of this hoisting construction technology are: (1) Each cladding must be processed, welded, and the lugs are cut, which is labor-intensive , and the construction efficiency is low; (2) Processing, welding, and cutting lifting lugs consume a lot of mechanical shifts, raw materials, welding materials and other consumables, which is not conducive to cost saving; (3) welding and cutting of lifting lugs will cause certain damage to the plate end. Dust generated when the lifting lugs are worn off will cause contamination of the transverse seam position at the lower end of the cladding, thus causing welding quality risks; (4) During the cutting of lifting lugs, there are safety risks of mechanical injury and falling objects; (5) It takes a long time for the cover to be in place and fixed

Embodiment 1

[0034] see Figure 1-2 , a nuclear power plant stainless steel pool cladding hoisting system, including lifting equipment 1, lifting lugs 2, adjustable hangers 3 for hoisting stainless steel cladding panels, sliding guide rails 4, sliding decks 5 and fixed decks 6; the adjustable The hanger 3 is composed of a hanger main body 31, a hanger beam 32 arranged at the top of the hanger, and a hanger base 33 arranged at the bottom of the hanger. The stainless steel cladding plate in this embodiment is a plane cladding plate 34, so the design can The hanger body of the adjustable hanger 3 is a triangular structure formed by welding L40×4 stainless steel angle steel. The angle steel is wrapped with a special cotton blanket for stainless steel protection to ensure that the stainless steel cladding panel is not damaged during the hoisting process. The length and width of the plane cladding panel are 996mm×1996mm, the single weight of the plane cladding panel is no more than 70kg, multipl...

Embodiment 2

[0040] see Figure 4 and Figure 6 , a nuclear power plant stainless steel pool cladding hoisting system, including lifting equipment 1, lifting lugs 2, adjustable hangers 3 for hoisting stainless steel cladding panels, sliding guide rails 4, sliding decks 5 and fixed decks 6; the adjustable The hanger 3 is composed of a hanger main body 31, a hanger beam 32 arranged on the top of the hanger, and a hanger base 33 arranged at the bottom of the hanger. The stainless steel cladding plate in this embodiment is a corner cladding plate 35, so the design can The hanger main body of the adjustable hanger 3 is a square structure formed by welding L40×4 stainless steel angle steel.

Abstract

The invention discloses a nuclear power station stainless steel pool cover lifting system and a construction method thereof. The system includes lifting equipment, a lifting lug, an adjustable hangerused for lifting stainless steel cover plates, a sliding guide rail, a sliding clamping seat, fixed clamping seats and the like. The method includes design and manufacturing of a lifting tool, connection and mounting of the lifting equipment and the tool, lifting system simulation test, assembly of the stainless steel cover plate and the lifting system and lifting positioning and adjustment. The nuclear power station stainless steel pool cover lifting system and the construction method thereof eliminate the operation steps of processing, welding and lifting lug cutting of each cover plate, greatly improves the operation efficiency and reduces the safety risk. The method can realize simultaneous construction of multiple walls and greatly improves the construction efficiency. Secondly, the construction process does not entirely rely on cranes in a workshop, which avoids cross construction.

Description

technical field [0001] The invention belongs to the technical field of installing stainless steel pools in nuclear power plants, and in particular relates to a cladding hoisting system for stainless steel pools in nuclear power plants and a construction method thereof. Background technique [0002] The stainless steel pool of the nuclear power plant is used as the liquid medium. Generally, a layer of 3-6mm stainless steel cladding panels are installed on the concrete wall and floor as the inner lining by the post-attachment method. Welding thus securely connects with the concrete main structure. In order to ensure the construction quality of the stainless steel pool and facilitate installation and construction, the stainless steel cladding panel is fractally designed into a large number of rectangular square panels and corner panels, so the pool cladding square panels and corner panels are small in size, small in size variation range, and have a large number of components of...
