Description

Technical Field

[0001] This utility model relates to the field of turning gear technology for hydro-generators, and in particular to a turning gear tool for a vertical hydro-generator. Background Technology

[0002] Turning the shaft is an indispensable part of the installation, inspection, and maintenance of vertical hydro generators. The shaft system of a vertical hydro generator is a critical component; its installation accuracy and operating condition directly affect the overall power generation efficiency and stability of the unit. The purpose of turning the shaft is primarily to check the tilt and bending of the unit's shaft. Through precise turning measurement data, the shaft can be analyzed and addressed, thereby accurately determining the center position of the guide bearings and ensuring the shaft system is in good operating condition.

[0003] However, most existing turning tools for vertical hydro generators clamp the generator shaft using curved plates on both sides. This clamping method increases the friction between the hydro generator shaft and the curved plates, thereby increasing the damage to the generator shaft. Therefore, those skilled in the art have provided a turning tool for vertical hydro generators to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a turning tool for a vertical hydro generator. This device facilitates quick positioning of the vertical hydro generator shaft by workers and reduces friction during installation and positioning.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A turning tool for a vertical hydro generator includes a bracket. The bracket includes two fixed rings, and a positioning mechanism is provided between the two fixed rings at their triangular positions. The positioning mechanism includes a threaded sleeve, and an adjusting rod is threadedly connected inside the threaded sleeve. An installation handle is rotatably connected to one end of the adjusting rod that passes through the threaded sleeve. An installation ring is fixedly provided inside the installation handle. A positioning ring is rolled around the outside of the installation ring by ball bearings. The inner sidewall of the positioning ring is flat. A rotating mechanism is fixedly provided between the two fixed rings at their triangular positions opposite the positioning mechanism.

[0007] Furthermore, the rotating mechanism includes a fixed block, a lever is inserted into the center of the fixed block, a locking hole is opened in the center of one end of the lever that passes through the fixed block, and an insert rod is inserted into the inner end of the lever, the insert rod passing through the locking hole;

[0008] With the above technical solution, by inserting the lever into the fixed block, the operator can push the lever to rotate the bracket, thereby performing the rotation operation.

[0009] Furthermore, a through hole is provided on one side of the upper end face of the insertion rod, and a connecting rope is fixedly connected to the side of the upper end face of the insertion rod away from the through hole. A clamping rod is fixedly connected to one end of the connecting rope, and the clamping rod is engaged inside the clamping hole.

[0010] The above technical solution limits the lever by inserting the plug rod into the locking hole of the lever and locking the lever into the locking hole of the plug rod.

[0011] Furthermore, an anti-slip sleeve is fixedly fitted on the outer wall of the end of the lever away from the insertion rod;

[0012] The above technical solution improves the anti-slip effect of the lever by using an anti-slip sleeve.

[0013] Furthermore, a rotating seat is connected between the adjusting rod and the mounting handle, the inner end of the rotating seat is fixedly connected to the mounting handle, and the adjusting rod extends into the rotating seat and is rotatably connected to it;

[0014] The above technical solution allows the adjusting rod to rotate via the rotating seat, which in turn moves the mounting handle.

[0015] Furthermore, a fixing pin is inserted into the upper end of the mounting handle, and the fixing pin passes through the middle of the mounting handle and the mounting ring;

[0016] The above technical solution uses a fixing pin to limit the position of the mounting handle and the mounting ring.

[0017] Furthermore, lifting lugs are fixedly installed at the four corners of the upper end of the fixing ring;

[0018] Using the above technical solution, the fixed ring is hoisted by connecting an electric hoist with a lifting lug.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model proposes a turning tool for a vertical hydro-generator. The device clamps and positions the shaft of the vertical hydro-generator using rollers, reducing friction during installation. One side wall of the roller is set as a plane, and the distance between the three positioning discs can be adjusted, making it convenient for workers to quickly position the shaft of the vertical hydro-generator.

[0021] 2. The present invention proposes a rotating tool for a vertical hydro-generator. The rotating mechanism of the device can be disassembled from the bracket. The lever is inserted into the fixed block, and then the lever is limited by the insertion rod. This facilitates on-site installation and operation of the rotating mechanism when using the rotating tool, and solves the problem of large storage space caused by the large size of the rotating tool.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] A rotating seat 23 is connected between the adjusting rod 22 and the mounting handle 24. The inner end of the rotating seat 23 is fixedly connected to the mounting handle 24. The adjusting rod 22 extends into the rotating seat 23 and is rotatably connected to it. When the adjusting rod 22 is rotated by the rotating seat 23, it drives the mounting handle 24 to move. A fixing pin 26 is inserted at the upper end of the mounting handle 24. The fixing pin 26 passes through the middle of the mounting handle 24 and the mounting ring 25. The fixing pin 26 limits the mounting handle 24 and the mounting ring 25. Lifting lugs 12 are fixedly installed at the four corners of the upper end of the fixing ring 11. An electric hoist is connected through the lifting lugs 12 to lift the fixing ring 11.

[0032] Reference Figure 1 and 5 The rotating mechanism 3 includes a fixed block 31, a lever 32 inserted into the center of the fixed block 31, a locking hole 33 in the center of one end of the lever 32 that passes through the fixed block 31, and an insert rod 34 inserted into the inner end of the lever 32 that passes through the locking hole 33. By inserting the lever 32 into the fixed block 31, the operator can rotate the bracket 1 by pushing the lever 32, thereby performing the rotation operation. A through hole 35 is opened on one side of the upper end face of the insert rod 34. A connecting rope 36 is fixedly connected to the upper end face and the side away from the through hole 35. A locking rod 37 is fixedly connected to one end of the connecting rope 36. The locking rod 37 is engaged inside the locking hole 33. By inserting the insert rod 34 into the locking hole 33 of the lever 32, the locking rod 37 is engaged into the locking hole 33 of the insert rod 34, thereby limiting the lever 32. An anti-slip sleeve 38 is fixedly sleeved on the outer wall of the end of the lever 32 away from the insert rod 34. The anti-slip sleeve 38 improves the anti-slip effect of the lever 32.

[0033] Working principle: When using the turning tool for this vertical hydro-generator, the bracket 1 is hoisted onto the vertical hydro-generator by an electric hoist. Then, the adjusting rod 22 is rotated to move the positioning ring 27. The positioning ring 27 abuts against the generator shaft, so that the plane 28 fits against the generator shaft, thus positioning the generator shaft. The lever 32 is inserted into the fixing block 31, and then the lever 32 is limited by the insert rod 34. The operator can push the lever 32 to turn the vertical hydro-generator.
