Embodiment Construction

[0013] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] The sliding opening and closing mechanism of the temporary roof is mainly composed of beams, rails, mechanical limiters, driving trolleys, driven trolleys, roofs, sensors, etc.

[0015] The upper and lower two-layer linear tracks are built on the containment, and the two top covers are respectively installed on the trolleys on the two-layer tracks, and the top cover is moved in translation through the sliding of the trolleys on the tracks, so as to realize the overall opening of the top cover and off.

[0016] Each layer of track is composed of two parallel tracks. The trolleys are symmetrically arranged on the two tracks. The trolleys are divided into driving trolleys and driven trolleys. The driving trolleys are driven by...

Abstract

The invention discloses a reactor building temporary roof sliding opening-closing mechanism. The mechanism comprises a rail (6), driving trolleys (8), a driven trolley (9), a roof and a sensor. The rail (6) is divided into an upper layer and a lower layer, each layer of the rail (6) is composed of two parallel guide rails, the trolleys are symmetrically arranged on the guide rails, and at least one driving trolley (8) is arranged on each guide rail. The roof is divided into two pieces, one piece of the top cover is installed on the corresponding trolley of one layer of the rail, and the sensoris installed at the corresponding position of the top of the roof and is used for controlling the moving position of the roof. According to the mechanism, the roof is opened in sunny days so as to meet the requirements of lighting, ventilation and hoisting, and the roof is closed in rainy and snowy days so as to protect equipment and materials in a containment from being eroded and ensure that the construction operation in the containment is not influenced by external weather.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant construction and safety, and in particular relates to the opening and closing technology of the top cover of the nuclear power plant. Background technique [0002] At present, the new-generation nuclear power reactor plant in my country basically adopts the open-top construction method. The construction and installation phase lasts for a long time, generally 3 to 5 years, and external cranes are required to frequently lift equipment and materials during the construction process. During the construction process, in order to avoid wind, rain, and snow weather from having a greater impact on the construction period and the equipment in the workshop, it is necessary to adopt a temporary roof that can be opened and closed to meet the needs of equipment hoisting and equipment corrosion protection. [0003] The temporary top cover is required to meet the requirements of lighting, ventilation ...
