[0002] The turbine servomotor is installed on the servomotor seat at the top of the turbine. Its main function is to convert the oil pressure into the push-pull force of the adjusting rod, thereby driving the blade angle adjustment operating mechanism to convert the axial movement into the rotation of the blade around the pivot to achieve the adjustment of the blade angle.

[0003] When the turbine is being overhauled, it is lifted to the maintenance platform with an electric hoist. The current lifting method is to thread the rope through the ear plates at both ends of the relay, and then connect the lifting rope to the hook to lift the relay. Although this lifting method has a simple structure, it lacks stability during the lifting process, and the rope is easily slipped when threading through the pin shaft holes on the ear plates, resulting in high lifting risks and low efficiency. Summary of the invention

[0006] Preferably, the outer diameter of the hanging plate is smaller than the outer diameter of the relay.

[0007] Preferably, a connecting platform is coaxially fixedly provided on the top of the hanging plate, the connecting ring is fixed on the connecting platform, and connecting ribs are provided between the side wall of the connecting platform and the hanging plate.

[0008] Preferably, a mounting groove is provided on the top of the connecting platform, and the connecting ring is located in the mounting groove and is connected to the bottom surface of the mounting groove by bolts.

[0009] Preferably, a conical reinforcement structure is provided at the bottom of the hanging plate.

[0010] The utility model provides a relay hoisting tool, which provides a hoisting platform, a hoisting hook of a winch is connected to the center of the hoisting platform, the edge of the hoisting platform is connected to the hoisting rope, the relay is connected through a connecting head at the end of the hoisting rope, after the original bolts at the end of the relay are taken out, the connecting head is installed at the end of the relay, and then the hoisting hook is connected through a connecting ring, so that the relay can be stably hoisted, and the work of threading and tying the hoisting rope is omitted, thereby improving the efficiency of the hoisting construction.

[0017] like Figure 1-4 The utility model provides a relay hoisting tool, comprising a hoisting plate 1, a hoisting rope 5 connected to the edge of the hoisting plate 1 and a connecting ring 3 fixed in the middle of the top of the hoisting plate 1, the movable end of the hoisting rope 5 is fixedly connected with a connecting head 7, the connecting head 7 is provided with a screw, and the size of the screw is the same as the size of the bolt at the end of the relay 8, and the hoisting rope 5 is evenly distributed around the center of the hoisting plate 1.

[0018] Connect the hook at the end of the winch wire rope 9 through the connecting ring 3. Since four lifting ropes 5 are connected to the lifting platform 1, the four lifting ropes 5 are distributed in the four directions of the lifting platform 1. Take out the bolts at the four directions of the end of the relay 8, and then connect the four connecting heads 7 to the ends of the relay 8 respectively. Then, pull up the relay 8 by winding the wire rope 9 with the winch and lift it to the installation position.

[0019] In order to facilitate the installation of the connecting head 7 on the relay 8 and prevent the lifting rope 5 from getting tangled during rotation, an opening is provided at the edge of the lifting plate 1. The lifting rope 5 passes through the opening and is fixedly connected to the connecting block 6. The outer diameter of the connecting block 6 is larger than the aperture of the opening. When the connecting head 7 is rotated, the lifting rope 5 can rotate with the connecting head 7.

[0020] like Figure 2As shown, when the relay 8 is lifted horizontally, by threading the two connectors 7 on the same side of the lifting platform 1 onto the same end of the relay 8, and utilizing the equal length of the lifting rope 5, after the lifting platform 1 is lifted by the wire rope 9, the axis of the lifting platform 1 can be controlled to be approximately located at the center of the horizontal relay 8. In this way, when the relay 8 is arranged, the horizontal relay 8 can be directly lifted to the installation position. Compared with the vertical lifting form, the work of adjusting the installation position after the lifting is completed can be avoided, thereby improving the installation efficiency of the relay 8.

[0021] like Figure 1 As shown, in order to ensure the stability of the hoisting process, the outer diameter of the hoisting plate 1 is smaller than the outer diameter of the relay 8. During hoisting, the hoisting rope 5 is ensured to be in an inclined and tensioned state, and the relay 8 is located directly below the hoisting plate 1.

[0022] like Figure 4 As shown. A connecting platform 2 is coaxially fixedly arranged on the top of the hanging plate 1, the connecting ring 3 is fixed on the connecting platform 2, and connecting ribs are arranged between the side wall of the connecting platform 2 and the hanging plate 1. The strength of the middle part of the hanging plate 1 is enhanced by arranging the connecting platform 2, and the strength between the connecting platform 2 and the hanging plate 1 is enhanced by the connecting ribs.

[0023] like Figure 4 As shown. The top of the connecting platform 2 is provided with a mounting groove 4, and the connecting ring 3 is located in the mounting groove 4 and connected to the bottom surface of the mounting groove 4 by bolts. When connecting the hook, the hook is first inserted into the connecting ring 3, and then the connecting ring 3 is inserted into the mounting groove 4, and the connecting ring 3 is locked in the mounting groove 4 by bolts, while the space of the connecting ring 3 is reduced, and the hook is squeezed to ensure the strength of the connection between the hook and the connecting ring 3.

[0024] like Figure 1 As shown, in order to increase the strength of the edge of the hanging plate 1, a conical reinforcement structure is arranged at the bottom of the hanging plate 1.
