Description
Technical Field
[0001] The utility model relates to the technical field of installation of thrust bearings of hydro-generators, in particular to a hoisting device for thrust bearings. Background Art
[0002] In a hydro-generator, the thrust bearing uses a Babbitt alloy bearing, which is shaped like a sector. To ensure excellent frictional performance during operation, the surface roughness of the thrust bearing is carefully adjusted to a relatively high level. However, the hardness of the Babbitt alloy is relatively low, and even a slight collision may cause pits on the surface, which undoubtedly increases the difficulty and cost of maintenance. In the current unit overhaul process, the hoisting of the thrust bearing is a key task. Traditional hoisting methods usually use a combination tool of a lifting ring and a hemp rope.
[0003] However, this method is often accompanied by a potential risk during use: the lifting ring may collide with the bearing surface, and when the thrust bearing is lifted using the lifting lug, it is very easy to collide with the small spring and cause it to shift. Therefore, it is necessary to conduct in-depth research and improvement on the hoisting tools and methods of the thrust bearing to ensure that the hoisting work of the thrust bearing can be completed safely and efficiently during the overhaul process, thereby avoiding the situation of the lifting ring colliding with the bearing surface and the small spring. Summary of the Utility Model
[0004] The utility model provides a hoisting device for a thrust bearing, aiming to solve the problems in the prior art that the lifting ring may collide with the bearing surface, and when the thrust bearing is lifted using the lifting lug, it is very easy to collide with the small spring and cause the thrust bearing to shift.
[0005] To solve the above technical problems, the technical solution adopted by the utility model is as follows:
[0006] A hoisting device for a thrust bearing includes a horizontal plate arranged at the top of the thrust bearing. A plurality of lifting holes are provided on the horizontal plate. A first connecting plate is detachably arranged on the side of the horizontal plate close to the outside of the thrust bearing. Threaded holes are provided on both the first connecting plate and the outside of the thrust bearing. When the first connecting plate forms a limiting fit with the horizontal plate, the threaded holes of the first connecting plate correspond to and coincide with the threaded holes of the thrust bearing. A threaded fastener is in threaded fit in the coincided threaded holes. The first connecting plate and the thrust bearing form a linkage fit through the threaded fastener;
[0007] A plurality of second connecting plates are arranged on the side of the horizontal plate close to the inside of the thrust bearing. The second connecting plates all form a detachable limiting fit with the limiting grooves arranged on the inside of the thrust bearing.
[0008] Preferably, a spacer plate is clamped between the horizontal plate and the thrust bearing.
[0009] More preferably, the spacer plate forms a detachable fixed fit with the horizontal plate.
[0010] Further, the horizontal plate includes a vertical portion and a horizontal portion, and the vertical portion and the horizontal portion cooperate to form a "T" - shaped structure. The vertical portion is arranged along the middle line position of the thrust bearing pad and extends towards the outside of the thrust bearing pad, and the horizontal portion is arranged along the inner edge of the thrust bearing pad. The first connecting plate is arranged at one end of the vertical portion far from the horizontal portion, and the second connecting plate is arranged at one end of the horizontal portion far from the vertical portion.
[0011] Furthermore, the first connecting plate includes a linkage plate arranged vertically. A limiting block is provided at the top of the linkage plate, and a limiting hole is provided at one end of the vertical portion far from the horizontal portion.

[0014] Specifically, the second connecting plate includes a hanging portion arranged vertically. The top of the hanging portion forms a fixed fit with the horizontal portion, and a hook portion perpendicular to the hanging portion is provided at the bottom of the hanging portion. The hook portion is embedded in the corresponding limiting groove and forms a hanging connection with the limiting groove.
[0015] Furthermore, lifting holes are provided at both ends of the horizontal portion far from the vertical portion, and a lifting hole is provided at one end of the vertical portion far from the horizontal portion.
[0016] Furthermore, the vertical portion and the horizontal portion are integrally formed.

[0020] (3) A spacer is provided on the tension plate to prevent the thrust bearing pad from being bumped and damaged by friction during hoisting.
[0021] (4) The three lifting rings enable the thrust bearing pad to have a high levelness during hoisting, facilitating the adjustment of the installation position of the thrust bearing pad and having good adjustment and stability performance for the horizontal lifting out of the thrust bearing pad.

When in use, first place the horizontal plate 1 on the thrust bearing 7 and slide it outward along the center line position of the thrust bearing 7 until the second connecting plate 6 forms a limit fit with the limit groove 8 on the inner side of the thrust bearing 7. At this time, the inner side of the thrust bearing 7 is linked with the horizontal plate 1 through the second connecting plate 6. After the limit fit of the second connecting plate 6 is completed, the first connecting plate 2 is installed in a limited way, so that the threaded holes 5 of the first connecting plate 2 correspond to and coincide with the threaded holes 5 of the thrust bearing 7.
