The outer ring 125 of the roller 120 rotates by the bearing 123 fixed around the rotating shaft 121 in a state where the 121 is inserted and fixed. In addition, the side of the roller 120 configured as described above is formed with a female threaded hole 127 to which the eye bolt can be fastened so as to lift and move the roller 120, and also extends to the inner bearing 123 on the rotating shaft 121. The lubricating oil supply path 129 is formed to supply lubricating oil to the inner bearing 123.

Meanwhile, as shown in FIG. 3A, the rod 141 of the plurality of screw jacks 140 is fixed to the bottom surface of the roller bracket 130, and guides 133 are fixed to both sides. Here, the guide 133 is a cylindrical beam structure.

In addition, a plurality of screw jacks 140 are mounted and fixed to the trolley 150, and the guide 133 is positioned through the trolley 150. More specifically, the bush 150 is fixed to the trolley 150, and the guide 133 is positioned through the bush 151.

Accordingly, when the screw jack 140 is operated, the rod 141 of the screw jack 140 moves upward and downward and raises or lowers the roller bracket 130 upwards. Guide the vertical movement of the roller bracket 130.

Here, the plurality of screw jacks 140 are connected to one rotation shaft 143 and the screw jack 140 is operated by the rotation of the rotation shaft 143. And the handle 145 is fixed to the end of the rotating shaft 143 so that the operator can rotate the one rotating shaft 143.

On the other hand, the four wheels 160 are mounted on the bottom of the cart 150. The wheel 160 is rotatably mounted to a bracket fixed to the bottom of the trolley 150, and a protrusion 161 is formed on an outer circumferential surface of the wheel 160 to be fitted into a rail groove 101 formed at a bottom thereof. Therefore, the protrusion 161 is rotated in the state fitted in the rail groove 101, so that the trolley 150 moves linearly along the rail groove 101 in the horizontal direction without leaving the rail groove 101.

Meanwhile, the bracket 153 is fixed to the bottom of the cart 150 in the lateral direction, and a through hole through which the bolt 155 penetrates is formed in the bracket 153. The head of the bolt 155 penetrating the through hole is located inside the rail groove 101, and the male screw portion of the bolt 155 penetrates the through hole of the bracket 153. In such a structure, when the nut 157 is fastened after tightening the nut 157 to the male screw portion of the bolt 155, the head and the nut 157 of the bolt 155 press the inside of the bracket 153 and the rail groove 101 to the bogie. 150 is fixed without moving.

Hereinafter, the driving unit for rotating the turbine rotor mounted on the support will be described.

As shown in FIG. 4, the H beam 173 fixed to the bottom of the body 171 in the longitudinal direction of the rail groove 101, and penetrates the H beam 173 to the rail groove 101. A bolt 175 inserted therein, a motor 180 fixed to an upper surface of the body 171, a speed reducer 181 and a speed reducer for rotating the connected turbine rotor 1 by slowing down the rotational speed of the motor 180; 181 and the joint 183 connecting the turbine rotor (1).

The body 171 is a structure having an appropriate height to match the height of the turbine rotor 1 seated on the support 110 and the height of the reducer 181, and a bolt penetrating the H beam 173 fixed to the bottom ( The reducer 181 has a height corresponding to the turbine rotor 1 with the 175 fixed to the rail groove 101 at the bottom.

In addition, the joint 183 is a universal joint, and the turbine rotor 1 may be rotated by the power of the motor 180 even if the height of the turbine rotor 1 is slightly raised or lowered.

Here, the head of the bolt 155 penetrating the H beam 173 is located inside the rail groove 101, and the nut 157 is fastened to the male screw portion of the bolt 155 to tighten the nut 157, The driving unit 170 is fixed. On the contrary, when the nut 157 is loosened, the driving unit 170 moves linearly along the rail groove 101 in the horizontal direction.

Hereinafter, the operating relationship of the turning apparatus for assembling the turbine rotor configured as described above will be described.

The operator mounts the rotating shaft 121 of the roller 120 in the seating groove 131 of the roller bracket 130 in consideration of the diameter of the turbine rotor 1 so that the outer ring 125 of the roller 120 can rotate. do. In this state, the operator mounts the turbine rotor 1 between the two rollers 120 of the roller bracket 130 using a crane. Then both ends of the turbine rotor (1) is rotatable in a state seated on the roller (120).

When the motor 180 of the driving unit 170 is driven in this state, the power of the motor 180 is decelerated at a rotational speed according to the reduction ratio of the reduction gear 181 to the turbine rotor 1 through the joint 183. Delivered. Therefore, the turbine rotor 1 seated on the roller 120 is rotated by the power of the motor 180. In this way, while rotating the turbine rotor (1) to maintain and mount the blade or to the other components for maintenance and mounting.

In this state, in order to move the turbine rotor 1 in the vertical direction, the operator rotates the handle 145 installed on the support 110 to rotate the rotary shaft 143. Then, the plurality of screw jacks 140 connected to the rotary shaft 143 operate to raise the rod 141 upward, and the turbine rotor 1 seated on the roller bracket 130 by the rod 141 that is upwardly raised. Goes upward. On the contrary, when the rotation shaft 143 is rotated in the opposite direction, the rod 141 moves downward while the turbine rotor 1 moves downward.

Meanwhile, as the rod 141 moves, the roller bracket 130 moves up and down. At this time, the guide 133 fixed to the bottom of the roller bracket 130 also moves up and down to guide the guide direction.

In this way, the turbine rotor 1 is maintained and manufactured while the turbine rotor 1 is rotated and moved up and down. And when the maintenance and production is finished, by loosening the nut 157 fastened to the bolt 155 inserted into the rail groove 101, the support 110 to move freely. When the nut 157 is pushed on the support 110 in a state in which the nut 157 is loosely loosened from the bolt 155, the wheel 160 of the support 110 moves horizontally while moving along the rail groove 101. In general, the support 110 is moved in a state in which the maintenance and manufacture of the turbine rotor 1 is lifted by a crane or the like, but in some cases, the support 110 may be moved in a state where the turbine rotor 1 is seated. have.

Meanwhile, the driving unit 170 also slides along the rail groove 101 when the driving unit 170 is pushed in a state in which the nut 177 is loosely loosened from the bolt 175.

Therefore, the operator rotates the turbine rotor 1 by using the driving unit 170 while the turbine rotor 1 is seated on the support 110 to perform the work. And when lifting or lowering the turbine rotor (1) operates the screw jack 140 of the support (110).

Thus, the operator uses the support 110 supporting the turbine rotor 1 and the driving unit 170 that rotates, while moving the turbine rotor 1 in a rotational and vertical direction without a separate device until the work is completed. Can work.

As described in detail above, the turning apparatus for assembling the turbine rotor of the present invention has the advantage that the turbine rotor can be rotated and moved without a separate device crane to maintain and manufacture the turbine rotor as conventionally.

In addition, in the related art, in order to rotate the turbine rotor, the turbine rotor is rotated while the belt is pulled up after the turbine rotor is wrapped with the belt connected to the crane. The drive unit is installed in the turbine rotor to directly rotate the turbine rotor, so that the operation is easy, and by connecting the motor and the turbine rotor with the universal joint, even if the turbine rotor is moved up and down, the power of the motor can be transmitted without difficulty.

Although the technical idea of the turning apparatus for assembling the turbine rotor of the present invention has been described with the accompanying drawings, this is illustrative of the best embodiment of the present invention and is not intended to limit the present invention.
