Description
Technical field
The present invention relates to the field of nuclear power construction personnel being carried out to technical training, particularly relate to nuclear power workmen in training process and carry out the nuclear power construction model of practice of construction operation training.
Background technology
Due to the expansion in nuclear power market, for meeting the need of market, shortening the construction of nuclear power station duration, when carrying out the construction of nuclear power station, newly introducing a large amount of workmens.But, workmen due to these new introducings does not install the experience of nuclear power station, speed of application is slow, and installation quality is poor, can not meet the quality requirements that nuclear power is installed, rework rate is high, for this reason, enter before working-yard starts to carry out nuclear power installment work the new workmen introduced, first will carry out skills training to ensure that operating efficiency and construction quality can meet construction needs to these workmens.
At present, the skills training method of normal employing first carries out theoretical training with paper document or e-file, carry out general practical operation training again, such as weld training, then also need under the leading of experienced workmen, enter working-yard to carry out watching and actual installation practice, and at least independently will carry out nuclear power construction through one and a half months to two months ability.The workmen of these new introducings is when entering working-yard and carrying out independent construction, and because reading graph ability is poor, level of skill is low, and speed of application is slow, and installation quality is poor, and can not meet the quality requirements that nuclear power is installed, rework rate is high, and then causes Construction of Nuclear Electricity efficiency low.As can be seen here, adopt and give training the new workmen introduced in this way, expend time in length, and result of training is poor, can not meet the demand improving Construction of Nuclear Electricity efficiency because of the nuclear power market expansion.
Summary of the invention
Slow for solving the nuclear power construction personnel speed of application of newly entering a profession, installation quality is poor, the problem of the demand of Construction of Nuclear Electricity efficiency can not be improved because meeting the nuclear power market expansion, the present invention proposes a kind of nuclear power construction model, this nuclear power construction model comprises support and portal structure, described support comprises at least two supporting legs, supporting leg described in each is provided with at least one trailing arm and one end of this trailing arm forms one deck bracket with described supporting leg vertical connection; Described portal structure comprises horizontal bridge shelf structure, corner portal structure and climbing portal structure; Described horizontal bridge shelf structure and described climbing portal structure are the rectangular tray of rectangle ladder or both ends open; Two crane span structure bars of the sweep of described corner portal structure are arc-shaped curved bar; Described horizontal bridge shelf structure and described corner portal structure are flatly arranged on described bracket, described climbing portal structure is arranged on the bracket of the stepped arrangement of described trailing arm, and connecting respectively by web member between adjacent horizontal bridge shelf structure, corner portal structure and climbing portal structure and/or between the crane span structure forming described horizontal bridge shelf structure, corner portal structure and climbing portal structure on same layer bracket.
The nuclear power construction personnel newly entered a profession, after carrying out theoretical training, can install it according to the installation drawing of nuclear power construction model and view and emulate repeatedly the nuclear power construction model of installation.Carry out in strict accordance with nuclear power construction flow process in installation process, and then be familiar with nuclear power construction flow process; In installation process and when viewing and emulating the nuclear power construction model of installation, repeatedly installation drawing and concrete workpiece being compared, improve the reading graph ability of these workmens; By concrete installation, improve speed of application and the level of skill of these workmens, and then improve installation effectiveness.Like this, after training fast, these workmens directly can enter nuclear power construction scene and carry out independent construction, and can ensure speed of application and construction quality, reduce rework rate, improve Construction of Nuclear Electricity efficiency.
