Mouth is corresponding with the T body of motor shaft coupling (5) one end, then movable hydraulic telescopic oil cylinder (1) makes cylinder rod linkage connector (4) one end
After being bumped into the T body of motor shaft coupling (5) one end in the card slot mouth of T shape, cylinder rod linkage connector (4) and motor shaft coupling are completed
(5) docking.
4. a kind of application method of hydraulic device for axial fan blade installation according to claim 1, feature
It is: after the docking of cylinder rod linkage connector (4) and motor shaft coupling (5), the cylinder rod (2) and motor shaft of hydraulically extensible oil (1)
(13) it is located at same straight line；Start oil pump after the docking of cylinder rod linkage connector (4) and motor shaft coupling (5), starts the same of oil pump
When, start the valve of the contraction of oil pump, the oil circuit for shrinking oil connection (18) passes through the hydraulic cylinder rod for making hydraulically extensible oil (1)
(2) it at the uniform velocity pressurizeed, shunk, while cylinder rod (2) is at the uniform velocity pressurizeed, shunk, driving is hydraulic to stretch cylinder rod (2) by shrinking
Contracting oil cylinder (1) and top pressure tube (3) are moved to opposite direction, and when top pressure tube (3) opposite direction moves, top pressure tube (3) end corresponds to fan blade
Wheel hub (14) side carry out integrated pushing, top pressure tube (3) push wind impeller boss (14) to wind impeller boss (14) keyway in fan blade
Hub spindle (16) key closes oil pump after docking completely, complete wind impeller boss (14) installation of motor shaft (13)；Complete motor shaft
(13) after wind impeller boss (14) installation, start the valve of the stretching of oil pump, the oil circuit of stretching oil connection (19) passes through hydraulic
So that the cylinder rod (2) of hydraulically extensible oil (1) at the uniform velocity pressurizeed, stretched out, oil pump is closed after cylinder rod (2) is fully extended, by logical
Cross manual operation, movable hydraulic telescopic oil cylinder (1) makes to be detached from motor shaft in the card slot mouth of the T shape of cylinder rod linkage connector (4) one end
After the T body of connector (5) one end, the motor shaft coupling (5) removed on wheel hub spindle nose (15) is rotated by manual operation opposite direction,
After fastening nut fixed wind impeller boss (14) are installed on wheel hub spindle nose (15), wind impeller boss (14) peace of motor shaft (13) is completed
Dress.
