[0006] The top plate is located above the thrust head and is provided with a plurality of thrust head connecting pieces mounted thereon. The bottom of the thrust head connecting piece is detachably connected with the thrust head. The jacking power source is a jack which is placed on the main shaft of the pumped storage power station generator through a base plate. The hydraulic rod of the jack drives the thrust head to move vertically relative to the main shaft of the pumped storage power station generator through the top plate and the plurality of thrust head connecting pieces, so as to separate the thrust head from the main shaft of the pumped storage power station generator.
[0007] Further, the top plate is a circular plate body, and the diameter of the top plate is the same as the diameter of the end face of one side of the thrust head. A plurality of through holes for mounting the thrust head connecting pieces are arranged circumferentially on the top plate, and the positions of the through holes are vertically coaxial with the positions of the threaded holes on the end face of one side of the thrust head.
[0008] Further, the thrust head connecting piece comprises a high-strength screw rod and a top plate positioning piece. The bottom of the high-strength screw rod is threadedly connected with the threaded hole on the end face of one side of the thrust head, and the top of the high-strength screw rod penetrates through the through hole arranged circumferentially on the top plate. The top plate positioning piece is a group of nuts threadedly connected with the high-strength screw rod. The nuts are respectively clamped on the top plate from above and below.
[0009] Further, a lifting ring is also installed on the top plate, and the lifting ring is located at the top center of the top plate and is threadedly connected with the top plate.
[0010] The utility model discloses the beneficial effect is:

[0017] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0018] For the dismantling operation of the thrust head in the maintenance process of the pumped storage power station generator, the embodiment provides a professional tool of uniform and fast pulling out the thrust head; as shown inFigure 1 and Figure 2 As shown, the specialized tooling for uniformly and quickly pulling out the thrust head includes a lifting power source 1, a top plate 2 that mates with the power source, and thrust head connectors 3. The top plate 2 is located above the thrust head 4, and four sets of thrust head connectors 3 are mounted on the top plate 2. The bottom of each thrust head connector 3 is detachably connected to the thrust head 4. The lifting power source 1 is a 60T jack, which is placed on the main shaft 6 of the pumped storage power station generator via a pad 5. The hydraulic rod of the jack, through the top plate 2 and the four sets of thrust head connectors 3, drives the thrust head 4 to move vertically relative to the main shaft 6 of the pumped storage power station generator, thus separating the thrust head 4 from the main shaft 6.
[0019] Specifically, such as Figure 1 and Figure 2 As shown, the top plate 2 in this embodiment is a circular plate made of 50*φ800 circular steel plate. The diameter of the top plate 2 is the same as the diameter of the end face on one side of the thrust head 4. Several through holes are provided on the circumference of the top plate 2 to fit the thrust head connector 3, and the position of the through holes is vertically coaxial with the position of the threaded hole on one side of the thrust head 4.
[0020] In this embodiment, the thrust head connector 3 includes an M80 high-strength screw 7 and a top plate 2 positioning component; as Figure 2 As shown, the bottom of the high-strength screw 7 is threadedly connected to a threaded hole on one side end face of the thrust head 4, as... Figure 1 and Figure 2 As shown, the top of the high-strength screw 7 passes through a through hole arranged circumferentially on the top plate 2. Figure 2 and Figure 3 As shown, the positioning component of the top plate 2 is a set of M115 nuts 8 that are threadedly connected to the high-strength screw 7. The set of nuts 8 are located above and below the top plate 2 respectively. The set of nuts 8 clamps the top plate 2 by adjusting the position of the nuts 8.
[0021] The installation and use process of this specialized tooling for uniformly and quickly pulling out the thrust head is as follows:
[0022] like Figure 2As shown, first, four groups of thrust head connecting pieces 3 are installed on one side end surface of the thrust head 4, the bottom of the M80 high-strength screw rod 7 of the thrust head connecting piece 3 is screwed with the thrust head 4; then the top plate 2 is installed through the four groups of thrust head connecting pieces 3; then the gasket 5 is placed on the main shaft 6 of the pumped storage power station generator, and the jacking power source 1 is placed on the gasket 5; finally, the position of the nut 8 on the high-strength screw rod 7 is adjusted, so that the jacking bottom is in contact with the jacking power source 1, and the top plate 2 is clamped and positioned through a group of nuts 8. At this time, the jacking power source 1 can be started, and the jacking power source 1 drives the thrust head 4 to move vertically relative to the main shaft 6 of the pumped storage power station generator through the top plate 2 and the four groups of thrust head connecting pieces 3, so that the thrust head 4 is separated from the main shaft 6 of the pumped storage power station generator, and the dismounting operation of the thrust head 4 is completed. The above process can be operated by one person, and since the jack is used as the power source, uniform stress of the thrust head 4 is ensured, and uneven force and errors that may occur in manual operation are avoided, thereby improving the construction precision, reducing the damage risk of the generator main shaft and the thrust head 4 itself, avoiding scratching the surface of the generator main shaft or the thrust head 4, and prolonging the service life of the equipment.
[0023] Further, as a preferred technical solution of the embodiment, as shown in Figure 3 As shown, the lifting ring 9 is also installed on the top plate 2 in the embodiment, the lifting ring 9 is located at the top center of the top plate 2 and is screwed with the top plate 2. The function of the lifting ring 9 is as follows: first, when there is no jacking power source 1 on the construction site, the lifting ring 9 can be used as a vertical pulling power source by cooperating with the travelling crane, the crane and the like to complete the dismounting operation of the thrust head 4; second, the lifting ring 9 can be used as a lifting point to hoist and transport the thrust head 4 separated from the main shaft 6 of the pumped storage power station generator to the ground for subsequent maintenance.
