High-speed blade mounting and fixing mechanism of hydroelectric station hydraulic turbine set

Abstract

The invention relates to the technical field of mechanical equipment, in particular to a high-speed blade mounting and fixing mechanism of a hydroelectric station hydraulic turbine set. Blades are used for fixing, so that the blade carrying and adjusting difficulty can be effectively reduced, a blade butt joint work is simplified, the manpower and time can be saved, the working efficiency is improved, workers are prevented from being scratched or injured when the blades are carried manually, meanwhile, the stability of the blades is improved, the height and angle adjusting accuracy of the blades is improved, the production quality of equipment is effectively improved, and the practicability and the reliability are improved. The mechanism comprises a workbench, four sets of self-locking universal wheels, a center control box, an air bin, an air guide channel, a piston plate, and four sets of first oil cylinder push rods; the four sets of self-locking universal wheels are evenly installed at the bottom of the workbench; the center control box is installed at the front side of the top of the workbench; the air bin is installed on the workbench; the air guide channel is arranged at thefront end of the air bin and communicated with the air bin; and the bottom of the air guide channel makes contact with the top of the workbench.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a high-speed blade installation and fixing mechanism for a water turbine unit of a hydropower station. Background technique [0002] As we all know, when the water turbine is assembled, the blades need to be docked on the mandrel in the equipment, and then welded. The blade docking work usually needs to manually lift the blades, and then adjust the angle and height of the blades to make them Corresponds to the angle and height of the mandrel. However, when using this method, due to the heavy weight of the blades, the manual docking work is more difficult, it takes more physical strength and time, the work efficiency is low, and it is easy to scratch the workers when the blades are transported. At the same time, the stability of manual docking is poor, and the accuracy of blade angle and height adjustment is poor, which will easily lead to poor equipment production qu...
