[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: a device for installing a steam turbine, including a mounting base 1, a base 11 fixedly connected to the lower end of the mounting base 1, and a first hydraulic cylinder 12 fixedly connected to the upper end of the mounting base 1. Three sets of first hydraulic cylinders 12 are fixedly connected to a first clamping plate 13 at opposite ends. An auxiliary component is fixedly connected to the upper end of the mounting base 1. The auxiliary component includes a fixing frame 21 fixedly connected to the upper end of the mounting base 1, and a motor 22 fixedly connected to one end of the fixing frame 21. The output shaft of the motor 22 passes through the fixing frame 21 and is fixedly connected to a threaded rod 23. The two ends of the threaded rod 23 are rotatably connected to the fixing frame 21. A threaded plate 24 is engaged on the outer side of one end of the threaded rod 23. The auxiliary component can quickly clamp and fix the blades to be installed and stably transport them to the installation position, thereby improving assembly efficiency, eliminating the need for manual pushing by workers, and saving the physical strength of the installers.

[0027] like Figure 2 and Figure 3 As shown, the threaded plate 24 is fixedly connected to two ends of a second hydraulic cylinder 25, and the end of the second hydraulic cylinder 25 away from the threaded plate 24 is fixedly connected to a third hydraulic cylinder 26. The positions of the two sets of second clamping plates 27 and anti-slip pads 28 are adjusted by the operation of the second hydraulic cylinder 25 and the third hydraulic cylinder 26.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the lower end of the third hydraulic cylinder 26 is fixedly connected to the second clamping plate 27, and the inner side of the opposite end of the second clamping plate 27 is fixedly connected to the anti-slip pad 28. The blade is clamped and transported by moving the second clamping plate 27 and the anti-slip pad 28.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, a limiting frame 29 is fitted on the upper end of the third hydraulic cylinder 26, and a limiting plate 210 is fixedly connected to the inner side of the limiting frame 29. The end of the limiting plate 210 away from the limiting frame 29 is inserted into the third hydraulic cylinder 26. When the third hydraulic cylinder 26 moves, it is fitted on the outside of the limiting plate 210. The movement of the third hydraulic cylinder 26 is restricted by the limiting frame 29 and the limiting plate 210.

[0030] like Figure 2 and Figure 4 As shown, the limiting frame 29 is fixedly connected to the two ends of the sliding plate 211, and the lower end of the sliding plate 211 is fitted with a slide rail 212. The lower end of the slide rail 212 is fixedly connected to the fixed frame 21. When the limiting frame 29 moves, it drives the sliding plate 211 to move within the slide rail 212. The sliding plate 211 and the slide rail 212 are used to restrict the movement of the limiting frame 29.

[0031] like Figure 4As shown, a roller 213 is inserted into the inner side of the lower end of the slide plate 211, and a limiting rod 214 is inserted inside the roller 213. The two ends of the limiting rod 214 are fixedly connected to the slide plate 211. When the slide plate 211 moves, it drives the roller 213 and the limiting rod 214 to move. Under the restriction of the limiting rod 214, the roller 213 rolls against the lower side of the slide rail 212. The rolling of the roller 213 assists the movement of the limiting frame 29, etc.

[0032] Working principle: When assembling the rotor and blades of the impeller, firstly, a crane is used to insert one end of the rotor into the slot at the upper end of the mounting base 1. Then, the first hydraulic cylinder 12 is activated to push the first clamping plate 13 to clamp and fix the rotor. Subsequently, the blades to be installed are placed under the two sets of second clamping plates 27. At this time, the third hydraulic cylinder 26 is activated to extend and push the second clamping plates 27 and anti-slip pads 28 downward. After the second clamping plates 27 and anti-slip pads 28 have moved to the designated position, the second hydraulic cylinder is activated. When cylinder 25 retracts, it causes the third hydraulic cylinder 26, the second clamping plate 27, and the anti-slip pad 28 to move closer to the blade. As the third hydraulic cylinder 26 moves, it is fitted onto the outside of the limiting plate 210 and moves under the restriction of the limiting plate 210 and the limiting frame 29. Then, the second clamping plate 27 and the anti-slip pad 28 clamp and fix the blade. After clamping and fixing, the second hydraulic cylinder 25 is closed, and the third hydraulic cylinder 26 is restarted. At this time, the third hydraulic cylinder 26 retracts, pulling the second clamping plate 27 and the anti-slip pad 28 upwards, thereby allowing the second clamping plate 27 to move closer to the blade. Plate 27 and anti-slip pad 28 drive the blade to move. When the blade moves to the designated position, the third hydraulic cylinder 26 is closed. Then, under the support of the fixed frame 21, the motor 22 is started. After the motor 22 starts, the output shaft drives the threaded rod 23 to rotate. After the threaded rod 23 rotates, it meshes with the threaded plate 24, causing the threaded plate 24 to drive the second hydraulic cylinder 25 and the third hydraulic cylinder 26 to move. When the third hydraulic cylinder 26 moves, it pushes the limit frame 29 to drive the slide plate 211 to move under the restriction of the slide rail 212. When the slide plate 211 moves, it drives the roller 213 and the limit rod 214 to move. At this time, the roller 213 rolls under the restriction of the limit rod 214 by contacting the slide rail 212. The rolling of the roller 213 assists the movement of the limit frame 29, etc. When the threaded plate 24 drives the clamped blade to the designated position, the motor 22 is closed. Then, the worker installs the blade on the rotor. After the installation is completed, the second hydraulic cylinder 25 is started again to extend, thereby pushing the third hydraulic cylinder 26 and the second clamping plate 27 away from the blade.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
