Description

Technical Field

[0001] The utility model relates to the technical field of flywheel disassembly, in particular to a flywheel disassembly device for a generator set. Background Art

[0002] The overhaul and disassembly of the flywheels of the generator sets in various power stations of the power system are all manual operations, which are labor-intensive and have high safety risks. Hydraulic equipment is also used in the existing technology to disassemble the flywheel, but the hydraulic equipment generally applies a thrust or pull force along the axial direction of the generator set to the flywheel, which requires a large force and has high requirements on the accuracy of the force direction. Any slight deviation can easily lead to damage to the generator shaft and the flywheel.

[0003] Prior art, patent number (CN202120914523.2) mentions a flywheel disassembly device for a generator set, including a fixing rod, at least two fixing rods, and an external thread is provided on the fixing rod near one end of the generator, and the fixing rod passes through the threaded hole on the flywheel and is connected to the threaded hole through the external thread; a hanging plate is also passed through the multiple fixing rods, and a reduction motor is provided on the hanging plate, and the motor shaft of the reduction motor is parallel to the fixing rod and is arranged in a direction away from the flywheel, and a driving gear is provided on the motor shaft of the reduction motor, and a driven gear meshing with the driving gear is provided on the fixing rod, which can effectively improve the efficiency of flywheel disassembly, speed up flywheel disassembly, ensure safety during flywheel hoisting, and reduce damage to the flywheel and the unit.

[0004] The traditional lateral disassembly method has been changed in the prior art, which will effectively solve the problem of using hydraulic equipment to disassemble the flywheel in the prior art. However, the hydraulic equipment generally applies thrust or pulling force to the flywheel along the axial direction of the generator set, which requires a large force and has high requirements on the accuracy of the force direction. A slight deviation will easily lead to damage to the generator shaft and the flywheel. However, the existing flywheel is set to a rotating installation and a snap-on installation. The rotating installation will facilitate disassembly and installation, but its overall structural stability is insufficient and it is not suitable for large generator sets. The snap-on installation has excellent structural stability, but does not utilize disassembly and assembly. Most of the flywheel disassembly devices on the current market are for rotating generator sets. For this reason, we propose a generator set flywheel disassembly device suitable for snap-on installation flywheels. Utility Model Content

[0019] First Embodiment

[0020] Please refer to Figures 1 to 3 , Figure 1 which is a schematic structural diagram of the whole of the first embodiment of the present utility model, Figure 2 which is a top view of the whole of the first embodiment of the present utility model, Figure 3 which is a side view of the whole of the first embodiment of the present utility model.

[0021] The present utility model provides a flywheel disassembly device for a generator set, including a motor set 101, a clamping block 102, a flywheel 103 and a positioning and disassembly assembly. The positioning and disassembly assembly includes a positioning column 104, a positioning ring 105, a limiting ring 106, a transmission gear 107, a power block 108, a support platform 109, a rotating gear 110, a connecting column 111, a connecting plate 112, an assembly rod 113 and an assembly ring 114. By the foregoing solution, the problem that there is no disassembly device for the flywheel 103 with a clamping installation in the existing market is solved. It can be understood that when the flywheel 103 with a clamping installation needs to be disassembled, the staff can assemble the assembly ring 114 and the assembly rod 113 onto the clamping block 102, and then start the power block 108 to effectively rotate the transmission gear 107, which will drive the rotating gear 110, thereby providing an outward pulling force. The connecting column 111 and the connecting plate apply power to the assembly rod 113, and thus the assembly ring 114 will squeeze and disassemble the flywheel 103, thereby actively and effectively solving the problem that there is no disassembly device for the flywheel 103 with a form - body installation in the existing market.

[0022] For this specific embodiment, the engaging block 102 is detachably connected to the motor group 101 and is located on one side of the motor group 101.

The power block 108 is detachably connected to the transmission gear 107 and is located at the end of the transmission gear 107 away from the positioning ring 105, and the power block 108 is arranged above the support platform 109. The support platform 109 is an auxiliary component for supporting the power block 108, and the power platform is a functional component for providing necessary power for the transmission gear 107.

[0024] Secondly, the rotating gear 110 is rotatably connected to the transmission gear 107 and is located above the transmission gear 107, and the rotating gear 110 is arranged inside the positioning ring 105. The connecting column 111 is detachably connected to the rotating gear 110 and is located on the side of the rotating gear 110 close to the motor group 101.

[0026] When the flywheel 103 with snap-in installation needs to be disassembled by using the present utility model, the staff will assemble the assembly ring 114 and the assembly rod 113 onto the snap block 102, and then start the power block 108 to effectively rotate the transmission gear 107, which will drive the rotating gear 110, thereby providing an outward pulling force. The connecting column 111 and the connecting disk apply power to the assembly rod 113, and thus the flywheel 103 will be extruded and disassembled by the assembly ring 114. This will actively and effectively solve the problem that there is no disassembly device for the flywheel 103 with a positive body installation in the existing market.
