[0002] In actual hydro-generator units, the thrust oil sump is located inside the lower frame center body. The center body has several windows, on which thrust bearing shoes are evenly arranged. Each window faces a thrust bearing pad. This structural form results in the situation that when the rotor is not lifted, to conduct inspection or replacement of the thrust bearing pad, we can only use a quick-installation scaffolding to build a maintenance platform, place a non-powered roller track on the platform, and implement inspection or replacement of the thrust bearing pad facing the window. Or, for a simpler method, manually extract the bearing shoe and use a crowbar to press down manually for bearing shoe extraction. However, the existing methods for extracting bearing shoes are time-consuming and laborious, with extremely low implementation efficiency, which is likely to affect the construction period, and it is difficult to accurately adjust the lifting height, easily causing scratches on the mirror plate. During the process of extracting the bearing shoe, there are potential safety hazards of being injured by heavy objects. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above deficiencies, and provide a device that can conduct inspection and disassembly of the thrust bearing shoe without lifting the mirror plate, so as to solve the problems of easy damage to the bearing surface and the mirror plate during the working process, and the problems of waste of manpower and time costs in the traditional disassembly steps, which affect the maintenance period of the bearing shoe.

A plurality of support columns are installed at the bottom of the base, and a guide rail mounting frame is installed at the top. A guide rail is installed inside the guide rail mounting frame. A sliding guide rail seat that fits and slides is installed on the guide rail. At both ends of the top of the sliding guide rail seat, a lead screw and a hydraulic jack are respectively arranged. A fixed block is sleeved on the outer wall of the lead screw. One side of the fixed block is fixedly connected with a U-shaped clamping groove. An connecting rod is clamped on the U-shaped clamping groove. The connecting rod is arranged parallel to the sliding guide rail seat. One end of the connecting rod close to the hydraulic jack is fixedly connected with a bearing shoe connecting seat. The end of the bearing shoe connecting seat far from the lead screw is fixedly connected with the bearing shoe through a locking bolt.

[0005] Preferably, the sliding guide rail seat includes two groups of sliding support blocks, which are fixedly connected by a connecting plate between the two groups of sliding support blocks. A carrying platform is fixedly connected to the tops of the two groups of sliding support blocks through bolts. The lead screw and the hydraulic jack are both installed on the top of the carrying platform.

[0006] Preferably, adjustable feet are provided at the bottom of the support columns.

[0007] Preferably, limit blocks are fixedly installed on both sides of the hydraulic jack at the top of the sliding guide rail base.

[0008] Preferably, a locking handwheel is arranged above the fixed block on the lead screw to press and fix the fixed block.

[0014] The present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0015] Such as Figure 1 Figure 2As shown in the figure, a disassembly and assembly device for the thrust bearing shoe of a semi-umbrella type hydrogenerator. A number of support columns are installed at the bottom of the base, and a guide rail mounting frame 7 is installed at the top. A guide rail 6 is installed inside the guide rail mounting frame 7. A sliding guide rail seat 5 that fits and slides is installed on the guide rail 6. At both ends of the top of the sliding guide rail seat 5, a lead screw 11 and a hydraulic jack 8 are respectively arranged. A fixed block is sleeved on the outer wall of the lead screw 11. A U-shaped clamping groove 1101 is fixedly connected to one side of the fixed block. A connecting rod 4 is clamped on the U-shaped clamping groove 1101. The connecting rod 4 is arranged parallel to the sliding guide rail seat 5. One end of the connecting rod 4 close to the hydraulic jack 8 is fixedly connected to a shoe connecting seat 2. The end of the shoe connecting seat 2 far from the lead screw 11 is fixedly connected to a shoe 10 through a locking bolt 1. In this embodiment, a fixed block is sleeved on the outer wall of the lead screw 11. This technical means is a conventional technical means in the art. It should be noted that a clamping block 1101 is fixedly connected to one side of the fixed block. The clamping block can be fixed to one side of the fixed block by welding, threaded connection, riveting, etc. It is mainly used to clamp the connecting rod 4 to ensure the stability of one end of the connecting rod 4 after connecting the shoe and to ensure the overall balance of the connecting rod 4 when sliding on the sliding rail.

[0016] Preferably, the sliding guide rail seat 5 includes two groups of sliding support blocks. The two groups of sliding support blocks are fixedly connected by a connecting plate. A carrying platform is fixedly connected to the tops of the two groups of sliding support blocks by bolts. The lead screw 11 and the hydraulic jack 8 are both installed on the top of the carrying platform. In this embodiment, since the shoe is heavy and the jack and the lead screw need to be carried to play a role in stabilizing the connecting rod 3, two groups of sliding support blocks are provided to further improve the stability.

[0017] Preferably, adjustable feet 9 are provided at the bottom of the support columns. The adjustable feet 9 are prior art and can be used to adjust the height of the overall device.

[0018] Preferably, limit blocks are fixedly installed on both sides of the hydraulic jack at the top of the sliding guide rail seat. When in use, the hydraulic jack 8 is placed between the limit blocks to prevent the jack from tilting and collapsing.

[0019] Preferably, a locking handwheel 3 is provided above the fixed block on the lead screw 11. When in use, since the shoe 10 is heavy, due to the weight of the shoe 10 at one end of the connecting rod 4, the connecting rod 4 may tilt when the jack rises. Therefore, a locking handwheel 3 is provided above the fixed block on the lead screw 11. When in use, the locking handwheel can be rotated to press down on the lead screw 11 to lock the fixed block, playing a fixing role and further stabilizing the connecting rod 4.

[0020] The specific steps of this embodiment are as follows: During installation, place the guide rail mounting bracket 7 on the top of the base, then install the guide rail 6 and the sliding guide rail seat 5, and sequentially install the lead screw 11 and the hydraulic jack 8 on the top of the sliding guide rail seat 5. Fix the connecting rod 4 to the fixing block on the lead screw 11. When in use, first install the tile connecting seat 2 on the connecting rod 4, align the center of the bolt hole of the tile connecting seat 2 with the center of the screw hole of the tile 10, and then fixedly connect the tile 10 through the locking thread 1. The tile locking bolt 1 connects and locks the tile 10. The hydraulic jack 8 is placed inside the limit block. Further, a special backing plate can also be used to adjust the gap between the jack and the connecting seat. While using the hydraulic jack 8 to lift the tile 10, one end of the connecting rod may tilt due to the weight. At this time, the locking handwheel 3 can be rotated downward to press the fixing block, further stabilizing the connecting rod 4, keeping the tile 10 and the connecting rod 4 relatively horizontal, and also ensuring the horizontal stability when using the guide rail to translate the tile 10. Finally, when the lower plane of the tile 10 rises to the appropriate position, push the entire sliding guide rail seat 5 out to the required position.
