Description
Technical Field
The invention belongs to the technical field of construction and safety of nuclear power plants, and particularly relates to a technology for opening and closing a top cover of a nuclear power plant.
Background
At present, a new generation of nuclear power reactor plants in China basically adopt an open-top construction mode, the duration of the construction and installation stage is long, generally 3 to 5 years, and an external crane is needed to frequently hoist equipment and materials in the construction process. In order to avoid the great influence of wind, rain and snow on the construction period and equipment in a factory building in the construction process, the openable temporary top cover is required to meet the requirements of equipment hoisting and equipment corrosion protection at the same time.
The temporary top cover can meet the requirements of lighting, ventilation and equipment hoisting in the construction process when being opened, and can achieve the functions of wind prevention and rain prevention when being closed. The opening and closing mechanism of the temporary top cover can be required to be opened and closed quickly and has higher reliability.
Disclosure of Invention
Before the open-top type nuclear power station containment building is not closed, a temporary top cover is needed to meet the requirements of lighting, equipment hoisting and equipment corrosion protection in the building and installation process.
In order to achieve the purpose, the invention provides a temporary top cover sliding opening and closing mechanism of a reactor factory building, which comprises a track (6), a driving trolley (8), a driven trolley (9), a top cover and a sensor, wherein the track is arranged on the top cover;
the tracks (6) are divided into an upper layer and a lower layer, each layer of tracks (6) consists of two parallel guide rails, trolleys are symmetrically arranged on the guide rails, and at least one driving trolley (8) is arranged on each guide rail; the top covers are divided into two parts, one of the top covers is arranged on the trolley on the layer of the track, and the sensor is arranged at a position corresponding to the top of the top cover and used for controlling the moving position of the top cover; the lid may completely cover the headspace when closed.
Preferably, the sensor may be a rotary encoder, a displacement sensor or a travel switch.
Preferably, a mechanical limit (5) is arranged on the outer side of the track (6) to limit the maximum opening range of the top cover.
Preferably, the opening and closing mechanism is installed on a beam (7) of the containment.
The openable top cover is arranged on the trolley, and the trolley is driven by the motor to move on the track to open and close the top cover, so that the top cover is opened to meet the requirements of lighting, ventilation and lifting in sunny days, and is closed in rainy and snowy days to protect equipment and materials in the containment from corrosion and ensure that construction operation in the containment is not influenced by external weather.

in the figure: 1. a top cover A; 2. a top cover B; 3. a sensor A; 4. a sensor B; 5. mechanical limiting; 6. a track; 7. a beam; 8. driving the trolley; 9. a driven trolley.
Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The temporary top cover sliding opening and closing mechanism mainly comprises a beam, a track, a mechanical limit, a driving trolley, a driven trolley, a top cover, a sensor and the like.
An upper layer of linear rails and a lower layer of linear rails are built on the containment, the two top covers are respectively installed on trolleys on the two layers of rails, and the top covers are moved in a translation mode through sliding of the trolleys on the rails, so that the top covers are integrally opened and closed.
Each layer of track consists of two parallel tracks, the trolleys are symmetrically arranged on the two tracks and are divided into driving trolleys and driven trolleys, and the driving trolleys are driven by motors and can move on the tracks. Each track is provided with at least one driving trolley and at least one driven trolley. The top cover is fixed on the trolley through a connecting piece and is opened and closed along with the movement of the trolley.
The control of top cap position can be carried out (the sensor includes but not limited to rotary encoder, displacement sensor, travel switch, proximity etc.) through the sensor, through driving motor's drive top cap removal reach required position to realize the function of opening and close of top cap.
The top cover A, B can be opened and closed independently to form the required hoisting space.
When the top cover needs to be closed, the driving trolley is controlled to drive the top cover A, B to move, so that the top cover A, B reaches a closed position, and the top space in the track is covered.
When the single-side space of the top cover needs to be opened for hoisting operation, the driving trolley under the top cover A or B is controlled to drive the part of the top cover needing to be opened to move until the required hoisting space is exposed.
When the top cover needs to be completely opened for middle hoisting, the driving trolley is controlled to drive the top cover A, B to move towards two sides respectively, and finally the two layers of top covers reach the completely opened position.
The limit position of the top cover is controlled by the sensor, and is limited by mechanical limit on the track, so that the moving range of the top cover is ensured not to exceed the limit range.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations. The foregoing examples or embodiments are merely illustrative of the present invention, which may be embodied in other specific forms or in other specific forms without departing from the spirit or essential characteristics thereof. The described embodiments are, therefore, to be considered in all respects as illustrative and not restrictive. The scope of the invention should be indicated by the appended claims, and any changes that are equivalent to the intent and scope of the claims should be construed to be included therein.
