[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 , Figure 2 As shown, in this example, the rotor disassembly and assembly tooling includes a lifting mechanism 1 and a guide ring 2. The lifting mechanism 1 includes a fixed plate 10, a bracket 11, a handle 12, a rotating shaft 13, and a support plate 14. The fixed plate 10 is flat as a whole. The fixed plate 10 includes a main body 101, a left plate body 102, a right plate body and an adjustment mechanism. The opposite sides of the main body 101 are connected to the left plate body and the right plate body through the adjustment mechanism.

[0023] The adjusting mechanism includes a bevel gear transmission mechanism 106, a second rotating shaft 104, and a second handle 107. Figure 1 As shown, a rectangular box body 103 is fixed at the bottom surface of the end of the main body 101, and a bevel gear transmission mechanism 106 is arranged in the cavity of the box body 103. The bevel gear transmission mechanism 106 is such that one bevel gear is in a horizontal state and fixed to the handle 2 107 below the box body, and the other bevel gear is arranged vertically and fixed to the horizontally arranged rotating shaft 2 104. The rotating shaft 2 104 is connected to the corresponding left plate body 102 or right plate body, such as a convex plate 105 formed on the bottom surface of the left plate body 102, and the rotating shaft 2 104 is threadedly engaged with the convex plate 105.

[0024] A guide mechanism is installed between the left plate 102, the right plate and the corresponding end of the main body 101, and the guide mechanism is such as a guide rod 108. Two guide rods 108 are fixed side by side at the ends of the left plate 102 and the right plate, and a guide hole is formed at the end of the main body 101, and the end of the guide rod extends into the guide hole.

[0025] The bracket 11 is composed of four rods, two rods are fixed at the bottom surfaces of the ends of the left plate 102 and the right plate respectively, and the rods are arranged longitudinally. The inner diameter of the cavity surrounded by the four rods is ≥ the length of the support plate 14 and the outer diameter of the guide ring 2. When in use, the handle 107 can be rotated, and the distance between the left plate 102 or the right plate and the main body 101 can be changed with the cooperation of the bevel gear transmission mechanism 106 and the rotating shaft 104, thereby adjusting the inner size of the bracket to adapt to more types of rotors, casings, etc.

[0026] The main body 101 of the fixing plate 10 is rotatably connected to the rotating shaft 13, and the handle 2 107 is fixed at the end of the rotating shaft 13 extending from the top surface of the fixing plate 10. The rotating shaft 13 below the fixing plate 10 is threadedly connected to the supporting plate 14. The supporting plate 14 has fixing holes formed at both ends. When in use, the bolts are passed through the fixing holes and then screwed into the docking holes at the end of the rotor to complete the fixation.

[0027] The length of the support plate 14 is ≤ the inner diameter of the guide ring 2. When in use, if the guide ring 2 is placed at the end of the casing, the bracket in the lifting mechanism is abutted against the casing end face around the guide ring, the rotor fixed on the support plate is placed in the ring opening of the guide ring, and then the handle is turned. Under the guidance of the guide ring to the rotor, the support plate drives the rotor to move down along the guide ring into the casing cavity, and the rotor does not collide with the casing cavity wall.

[0028] In addition, the support plate can also choose the same structure as the fixed plate. This structure refers to the docking structure of the left and right plates with the middle main body through an adjustment mechanism. The length of the support plate can be adjusted according to needs to facilitate docking with more types of rotors. Under this structure, only the guide ring needs to be replaced, which helps reduce the cost of use.

[0029] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
