Description

{SAFETY WORKBENCH FOR POWER GENERATION}

The present invention relates to a safety work platform for a power generation facility, and more particularly, to a safety work platform for a power generation facility, and more particularly to a safety work platform for a power generation facility, in which a rotating body such as a boiler or a turbine rotor of a power plant or various components are easily and conveniently guided, The present invention relates to a safety workbench for a power generation facility capable of efficiently carrying out visual inspection and nondestructive inspection during maintenance by safely supporting a rotating body such as a turbine rotor.

Generally, turbine rotor, which is a core equipment of a thermal power plant using coal as a raw material, consists of a shaft and a rotating blade, which converts thermal energy into mechanical energy and transfers it to a generator through the action of steam introduced into the casing.

Since turbine rotors are regularly inspected and checked for abnormalities, failure of the turbine during operation of the power plant is directly related to power generation and reliability of power generation. Therefore, it is planned to perform preventive maintenance work on site regularly .

However, these rotating turbine rotors work on the bottom of the turbine rotor when the bearing or sleeve is replaced or inspect the turbine rotor. Therefore, not only is the turbine rotor damaged on the floor while being crushed and scratched, The work is interrupted while being scratched, so that replacement or maintenance inspection of the bearing or the sleeve takes a long time, and the operation is cumbersome and troublesome.

Therefore, there is a utility model registration No. 20-0363293 and No. 20-0452895 in order to solve the above-mentioned problems. However, in order to place the turbine rotor by simply using a crane at a predetermined height, The turbine rotor needs to be precisely adjusted, the height can not be adjusted, safety is lowered, and the working time is long.

In order to solve the above-mentioned problem, Korean Patent Registration No. 1307762, No. 1335531, No. 1364436 and the like are available. However, since a large number of supports can not secure a sufficient working space, the operation is troublesome and thus, In addition to the inefficiency in consumption, the rotating body sometimes moves in the longitudinal direction while rotating due to various causes.

In such a case, when the turbine rotor is rotated on a conventional workbench, the turbine rotor is sometimes rotated forward or backward gradually to rotate, causing a plurality of blades or a plurality of blades formed on the rotating shaft to collide with each other or to generate friction.

Accordingly, the main object of the present invention is to provide a method of installing a rotating body or various parts such as a boiler or a turbine rotor of a power plant on a workbench in a simple, convenient, and stable manner while restricting various lengths of the rotating body, And to provide a safety workbench for a power generation facility that can perform visual inspection and nondestructive inspection efficiently during maintenance.

Another object of the present invention is to provide a safety workstation for a power generation facility that can easily perform various workings at a best position by simply adjusting the position of a rotating body such as a boiler or a turbine rotor of a power plant or a support for seating various components .

Another object of the present invention is to provide a safety workbench for a power generation facility that can smoothly guide and securely mount a rotating body such as a boiler or a turbine rotor of a power plant moved to a crane or various components even if they do not coincide precisely .

In order to achieve the above object, a safety work station for a power generation facility according to the present invention comprises: a base for separating the main plate from the main plate and adjusting the length thereof; A connecting plate for coupling the main plate of the length-adjusted state of the base before and after the connecting plate; A safety support which slides in a longitudinal direction by engaging a moving block with the main plate of the base, a supporting leg installed on the moving block, integrally coupling the engaging block to the upper end of the supporting leg and drilling a fastening hole perpendicularly to the engaging block; And a coupling member for coupling the coupling block to the coupling block of the safety support base downwardly and coupling both ends of the rotation member to block the cross section, wherein the coupling hole is rotatably coupled to the outer periphery of the coupling hole by a bearing, A safety guide formed in a lower side of the guide hole so as to be fastened to the engagement block; A wire rope connected to the safety guide through a support leg of the safety support; A lifting and lowering portion for adjusting the height of the support leg of the safety support; A length adjusting unit installed on the connecting plate to adjust the distance between the front and rear main plates; And a position adjusting unit coupled to the movement block of the safety support to adjust the position of the support leg to correspond to the fastening bar of the safety guide.

Accordingly, the safety workbench for a power generation facility of the present invention guides both ends of a rotating body or various parts of a boiler or a turbine rotor of a power plant to a fastening hole of a fastening block, and the fastening bar of the safety guide fastens to the fastening hole of the fastening block And the pressing jack presses the fastening bar to maintain a firmly engaged state, so that the rotating body can be safely placed on the work table, and thus a perfect and sufficient working space can be secured. As a result, In addition, it is possible to adjust the length of the main plate so as to apply it to the rotating body of various sizes so as to be safely laid.
