[0002] Equipment maintenance refers to technical activities carried out to maintain, restore and improve the technical status of equipment. It includes maintenance to keep the equipment in good technical status, repairs to restore its function after equipment deterioration or failure, and technical activities to improve the technical status of equipment. Steam turbine is a rotary steam power device. High-temperature and high-pressure steam passes through a fixed nozzle to become an accelerated airflow and then sprays onto the blades, causing the rotor with blade rows to rotate and perform work externally. It is the main equipment in modern thermal power plants.

[0003] At present, in order to ensure the normal use of the steam turbine, it is necessary to regularly inspect it and place it on a placement table for inspection. During the inspection process of different positions of the steam turbine, the staff needs to move and rotate according to the inspection position. When there are many maintenance personnel, the movement of the staff will be inconvenient, and the maintenance efficiency of the steam turbine will be slow. In view of this, we propose a steam turbine maintenance device with a rotating mechanism. Utility Model Content

[0023] Specifically, the pressing device 2 of the technical solution of the utility model includes a sliding rod 201, a pedal 202, a rack 203, a connecting rod 204, a pull rod 205, a fixed plate 206 and a telescopic spring 207. When the sliding rod 201 and the rack 203 are moved downward by the pedal 202, the rack 203 drives the gear 4 to rotate, thereby driving the bevel gear A5, the bevel gear B7 and the rotating shaft 6 to rotate. The rotating shaft 6 drives the placement table 8 to rotate, which is convenient for detecting the turbine on the placement table 8. The operation is simple and convenient, and the convenience is improved.

[0024] In one embodiment of the present invention, the support plate 3 is fixedly mounted on the inner wall of the base 1 to support and limit the rotation rod 301, thereby ensuring that the gear 4 and the bevel gear A5 can rotate.

[0025] Please continue reading Figure 1-Figure 4A support plate 3 is fixedly installed on the inner wall of the base 1, a rotating rod 301 passes through the middle of the support plate 3 and is rotatably connected to the rotating rod 301, the right end of the rotating rod 301 is fixedly connected to the gear 4, the rack 203 at the right rear end of the gear 4 is meshed, and the left end of the rotating rod 301 is fixedly connected to the bevel gear A5. A rotating shaft 6 passes through the middle of the base 1 and is rotatably connected to the rotating shaft 6, a bevel gear B7 is fixedly installed on the outer wall of the rotating shaft 6, and the bevel gear B7 is meshed with the bevel gear A5. A placing table 8 is fixedly installed on the upper end of the rotating shaft 6, a slot 9 is opened on the outer wall of the pull rod 205, and the slots 9 are provided in multiple groups and are arranged in an array shape. An insertion rod 11 is elastically connected to the outer wall of the right end of the base 1 through a torsion spring 10, and the insertion rod 11 is inserted into the slot 9, and a sliding rod 201 and a connecting rod 204 are slidably connected in the slide groove 101.

[0026] In the implementation mode of the utility model, in order to facilitate the fixed position of the steam turbine on the placement table 8, by inserting the insertion rod 11 into the slot 9 of the pull rod 205, the pull rod 205 and the rack 203 can be fixed and limited, thereby limiting the rotation of the bevel gear A5, the bevel gear B7 and the rotating shaft 6, thereby ensuring the stability of the steam turbine on the placement table 8 during maintenance.

[0027] During use, when it is necessary to rotate and overhaul the steam turbine on the placement table 8, the insertion rod 11 is pulled outward so that the insertion rod 11 is no longer inserted into the slot 9. At this time, the foot is pressed downward on the pedal 202, so that the pedal 202 drives the sliding rod 201 to move downward, and at the same time, the sliding rod 201 drives the rack 203 to move downward. When the rack 203 moves downward, it drives the gear 4 and the bevel gear A5 to rotate. When the bevel gear A5 rotates, it engages with the bevel gear B7, driving the bevel gear B7, the rotating shaft 6 and the placement table 8 to rotate, so as to facilitate the inspection of the steam turbine on the placement table 8. The operation is simple and convenient, and the convenience is improved. After the rotation of the steam turbine is completed, the insertion rod 11 is inserted into the slot 9 of the pull rod 205 again, and the placement table 8 is fixed and limited, thereby improving the stability during maintenance.
