Description
Technical field
The present invention relates to the nuclear power workmen is carried out the field of technical training, relate in particular in training process nuclear power workmen and carry out the nuclear power construction model that the practice of construction operation training is used.
Background technology
Because the expansion in nuclear power market for meeting the need of market, is shortened the construction of nuclear power station duration, when carrying out the construction of nuclear power station, has newly introduced a large amount of workmens.But because the experience that the workmen of these new introducings does not install nuclear power station, speed of application is slow; And installation quality is poor; Can not satisfy the quality requirements that nuclear power is installed, rework rate is high, for this reason; Before the new workmen who introduces gets into the working-yard and begins to carry out the nuclear power installment work, to carry out skills training to these workmens earlier and can satisfy the construction needs to guarantee operating efficiency and construction quality.
At present; The normal skills training method that adopts is to carry out theoretical training with paper document or e-file earlier; Carry out general practical operation training again; Such as welding training, need get under experienced construction personnel's leading also then that the working-yard is watched and actual installation practice, and will pass through one and a half months to two a month ability at least and independently carry out nuclear power and construct.When the workmen of these new introducings carried out the independence construction in the entering working-yard, because the interpreting blueprints ability, level of skill was low, and speed of application is slow, and installation quality is poor, can not satisfy the quality requirements that nuclear power is installed, the rework rate height, and then cause the nuclear power construction efficiency low.This shows, adopt this method that the workmen of new introducing is giveed training, the length that expends time in, result of training is poor, can not satisfy the demand that improves the nuclear power construction efficiency because of the nuclear power market expansion.
Summary of the invention
Slow for solving the nuclear power workmen speed of application of newly entering a profession; Installation quality is poor; Can not be because of satisfying the problem that the nuclear power market expansion improves the demand of nuclear power construction efficiency, the present invention proposes a kind of nuclear power construction model, and this nuclear power construction model comprises support and portal structure; Said support comprises at least two supporting legs, and the end that each said supporting leg is provided with at least one trailing arm and this trailing arm is connected to form one deck carriage with said supporting leg is vertical; Said portal structure comprises horizontal bridge shelf structure, corner portal structure and climbing portal structure; The rectangular tray that said horizontal bridge shelf structure and said climbing portal structure are rectangle ladder or both ends open; Two crane span structure bars of the sweep of said corner portal structure are circular-arc curved bar; Said horizontal bridge shelf structure and said corner portal structure flatly are installed on the said carriage; Said climbing portal structure is installed on the carriage of the stepped arrangement of said trailing arm, and between with the adjacent horizontal bridge shelf structure on one deck carriage, corner portal structure and climbing portal structure and/or form between the crane span structure of said horizontal bridge shelf structure, corner portal structure and climbing portal structure and connect through web member respectively.
The nuclear power workmen who newly enters a profession can construct that the installation drawing of model is installed it and the nuclear power construction model of installation is viewed and emulated times without number after carrying out theoretical training according to nuclear power.In installation process, carry out, and then be familiar with the nuclear power construction process in strict accordance with the nuclear power construction process; In installation process and when the nuclear power construction model of installation is viewed and emulated, repeatedly installation drawing and concrete workpiece are compared, improved these workmens' interpreting blueprints ability; Through concrete installation, improved these workmens' speed of application and level of skill, and then improved installation effectiveness.Like this, after training fast, these workmens can directly get into the nuclear power working-yard and carry out independent construction, and can guarantee speed of application and construction quality, have reduced rework rate, have improved the nuclear power construction efficiency.
Preferably; On the same side of said supporting leg, being provided with four is parallel to each other and trailing arm at regular intervals; And near the trailing arm of said supporting leg upper end and the upper end of said supporting leg certain distance is arranged, certain distance is arranged near the trailing arm of said supporting leg lower end and the lower end of said supporting leg.Further, be respectively arranged with the anchor plate that is connected with said supporting leg vertical fixing with fixing said supporting leg at the upper/lower terminal of said supporting leg.Nuclear power construction model is being installed and installed the back when it is viewed and emulated; The workmen can be familiar with the regularity of distribution of each supporting leg in the support and judge the type of the U type card that should select for use according to the selection type of supporting leg fast; And then when concrete construction, can apace trailing arm be installed on the supporting leg, and the spacing between two adjacent trailing arms is equated.
Preferably, when said horizontal bridge shelf structure and said climbing portal structure were the rectangle ladder, the connecting rod that connects two crane span structure bars of said rectangle ladder was parallel to each other and equidistantly arranges; When said horizontal bridge shelf structure and said climbing structure are rectangular tray, offer through hole in the bottom of said pallet.
Preferably, the sweep of said corner portal structure is the fan-shaped ring structure.Further, when said sweep was the fan-shaped ring ladder, the connecting rod that connects two crane span structure bars of said fan-shaped ring ladder pointed to this center of circle near the end in the concentrically ringed center of circle at said crane span structure bar place; When said sweep is the fan-shaped ring pallet, the both ends open of said pallet and offer through hole in the bottom.Further preferably, said through hole evenly distributes.
Preferably, said web member is a platy structure, and this platy structure abuts in the outside of said crane span structure bar and is connected with said crane span structure bar through bolt.
When nuclear power construction model being installed and after installation, it is viewed and emulated; The workmen can be familiar with the structure of portal structure and the difference between the dissimilar portal structure; And can judge dissimilar portal structures fast in the installation site on the support and then can be apace that portal structure is rack-mount when the concrete construction, and select for use different web members that they are linked together according to the installation site of two adjacent portal structures according to installation drawing.
