Description

Turbine rotor vibration balancing tool [0002]

The present invention relates to a detachable tool for a turbine rotary shaft vibration balancing device for shortening the working time and improving the workability in maintenance of vibration balance of a large turbine as a power plant and an industrial facility.

Generally, the field maintenance for the turbine vibration balancing is structured in such a structure that the worker can not approach the balancing plug which is intertwined like a net up to the piping within the limited space and the balancing plug inside, During the disassembly operation, the plug is removed with a detachable tool for the balancing plug at a distance away from the inside to the inside, and then the weight is again removed by using a detachment tool for the second weight Weight.

Also, during the assembling work, weight is attached by using a detachment tool for weight first and then assembled by attaching a plug to a detachment tool for a balancing plug secondarily.

However, when tightening or disassembling a hexagon L wrench type balancing plug with a detaching tool for a balancing plug provided by the manufacturer, wear on the surface that comes into contact with the detaching tool will occur, and a balancing plug ) And the operation time is delayed. In addition, the balancing plug is easily detached from the attaching / detaching tool during the work, and the work is interrupted.

In addition, when the weight is assembled or disassembled by the T-shaped handle of the detachment tool for the weight provided by the manufacturer, the handle is restrained to the adjacent equipment, and the torque is not properly exhibited, In addition, when the weight is fixed, it can not be disassembled by the work force of the worker, resulting in a delay in the work time and an excessive increase in the worker's physical power consumption.

1. Published Patent Application No. 10-2001-0064636 (2001. 07. 09.) 2. Japanese Unexamined Patent Publication No. 09-085634 (March 31, 1997) 3. Japanese Patent Application Laid-Open No. 10-249742 (1998. 09. 22.)

The present invention has been accomplished in order to solve such conventional problems, and has the following purpose.

The object of the present invention is to provide a detachable tool that improves workability by improving the internal and external structure of the detachable tool for a balancing plug, thereby shortening the working time and improving the convenience.

Another object of the present invention is to provide a detachable tool which improves workability by reducing the working time by changing the conventional T-shaped handle to a hexagonal handle structure.

In order to achieve the above-mentioned object, the present invention has a configuration in which a hexagonal handle having a coupling hole formed in its longitudinal direction in a longitudinal direction, a holder formed to be long in a hollow shape, and a socket head having an engagement groove for engagement with a balancing plug, An outer structure made up of: And a T-shaped handle disposed adjacent to the hexagonal handle and coupled with the socket with the hexagonal handle, a holder member coupled to the coupling hole through the coupling hole and the inside of the holder, and a screw- The present invention provides a detachable tool for balancing vibration of a turbine rotor shaft.

Thus, according to the present invention, it is possible to improve workability by improving the internal and external structure of the detachable tool for the balancing plug, thereby shortening the working time and improving the convenience, as well as improving the overall structure and improving the vibration balance of the large turbine The work efficiency can be improved by shortening the work time and improving the work convenience, and the work time can be shortened, thereby contributing to the reduction of the labor cost, the improvement of the work quality and the reliability of the maintenance.

FIG. 1 is a schematic cross-sectional view of a part of a preferred embodiment of the present invention,
FIG. 2 is a left side view of FIG. 1 showing a side view of a socket head of an outer structure,
Fig. 3 is a right side view of Fig. 1 showing a side view of a hexagonal handle of an outer structure. Fig.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in the drawing, according to a preferred embodiment of the present invention, there are provided a hexagonal handle 12 having a coupling hole 10 formed in its longitudinal direction in its inside, a holder 14 formed to be long in a hollow form, And a socket head (20) having an engaging groove (18) for engaging with the balancing plug (100) together with the outer structure (1); A T-shaped handle 30 positioned adjacent to the hexagonal handle 12 and coupled with the socket 200 together with the hexagonal handle 12; A holder member 32 which is engaged with the coupling hole 16 and an internal structure 3 which is formed by combining the threaded portion 102 of the balancing plug 100 and the coupling threaded head 34 Wherein the turbine rotating shaft is mounted on the turbine shaft.

At this time, the hexagonal handle 12 of the outer structure 1 has a hexagonal outer shape and is configured so as to be fixedly coupled with the socket 200 so as not to be offset from each other, The balancer plug 18 is formed to have a hexagonal shape so that the balancer plug 100 can be fixedly coupled to the balancer plug 100 so as not to face each other.

The inlet port 16a adjacent to the coupling hole 16 formed in the socket head 20 has a conical inclined cross section and is connected to the external structure 1 via the coupling hole 10 from the outside. And the inner structure 3 can be naturally inserted into the coupling hole 16 while being connected to the inlet portion 16a.

Hereinafter, the process of operation of the present invention will be described.

In the case of disassembling the previously installed balancing plug 100, as shown in Fig. 1, the coupling groove 18 of the socket head 20 and the one side of the balancing plug 100 of the outer structure 1 And the holder member 32 is held in the holder 14 through the coupling hole 10 together with the threaded head 34 by holding the T-shaped handle 30 in the internal structure 3, When the threaded head 34 reaches the threaded portion 102 of the balancing plug 100 via the engaging hole 16 on the threaded portion 16a of the balancing plug 100, The head 102 and the threaded head 34 are engaged with each other so as to be screwed together.

Thus, when the threaded portion 102 and the threaded head 34 are screwed together, the internal and external structures 3 and the balancing plug 100 are kept in a state of being coupled with each other, When the handle 12 and the T-handle 30 are coupled together with the socket 200 to rotate the balancing plug 100 in the separating direction, the operation of separating the balancing plug 100 can be performed naturally.

Of course, when the balancing plug 100 is to be coupled with the balancing plug 100, the balancing plug 100 and the inner and outer structures 3 and 1 are coupled to each other in a reverse order to the above- The hexagonal handle 12 and the T-shaped handle 30 together with the socket 200 are rotated in the direction of engaging the balancing plug 100 The work of combining the balancing plug 100 naturally may be performed, and the outer structure 1 may be separated after the inner structure 3 is firstly separated.

Therefore, according to the present invention, improvement of internal and external structure of the attaching / detaching tool for the balancing plug improves the workability by improving workability by shortening the working time and improving the overall structure and improving the vibration balance of the large turbine The work efficiency can be improved by shortening the work time at the time of work, and the work efficiency can be improved and the work time can be shortened, thereby contributing to the reduction of the labor cost, the improvement of the work quality and the reliability of the maintenance.
