Summary of the invention
The purpose of this utility model is the weak point in order to overcome background technology, and a kind of power station guide vanes of water turbine bottom bracket axle removal tool is provided.
To achieve these goals, the technical solution of the utility model is: power station guide vanes of water turbine bottom bracket axle removal tool, it is characterized in that: it comprises the provision for disengagement of being located at stator side, described provision for disengagement comprises the support pier being arranged on seat ring, be arranged on the jack on support pier, and the push rod being connected with bottom bracket axle bottom, between described jack and push rod, be connected with guide post, between guide post and support pier, be connected with the positioning sleeve that prevents that guide post from rocking.
In technique scheme, jack is mainly by guide post, push rod to be moved up or down, thereby bottom bracket axle is ejected by push rod, and then saves staff's labour intensity.The Main Function of support pier is support jack and positioning sleeve, and can avoid that length because of guide post is long causes guide post to fracture or bending.The Main Function of positioning sleeve is to prevent that guide post from shaking in the process of moving upward.The utility model is simple in structure, easy for installation, the labour intensity that can effectively reduce a staff.
The dual-side of described stator is equipped with provision for disengagement.
In technique scheme, the side of stator can only arrange a set of provision for disengagement, arrange two cover provisions for disengagement can make staff convenient eject bottom bracket axle, but due to insufficient space, be not suitable for arranging three covers or more provision for disengagement.
Between described support pier and jack, supporting seat is installed.
In technique scheme, supporting seat can make jack more firmly be fixed on support pier, can further improve job stability of the present utility model.
Described positioning sleeve comprises the locating dowel that many intervals are arranged and are connected with the upper end of support pier, and the location-plate being connected with the top of locating dowel, and location-plate is provided with the through hole mating with described guide post outer wall.
Described locating dowel is reinforcing rod or angle steel.
In technique scheme, positioning sleeve can also adopt other structure, as locating dowel replaced and become a columnar plate, jack is placed on this columnar plate.
To sum up, the utility model is simple in structure, easy for installation, the labour intensity that can effectively reduce a staff.

The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not form to restriction of the present utility model, only for example.Make advantage of the present utility model more know and easily understand by explanation simultaneously.
Consult accompanying drawing known: power station guide vanes of water turbine bottom bracket axle removal tool, it is characterized in that: it comprises the provision for disengagement 9 of being located at stator 10 sides, described provision for disengagement 9 comprises the support pier 7 being arranged on seat ring 8, be arranged on the jack 5 on support pier 7, and the push rod 1 being connected with bottom bracket axle 3 bottoms, between described jack 5 and push rod 1, be connected with guide post 2, between guide post 2 and support pier 7, be connected with the positioning sleeve 4 that prevents that guide post 2 from rocking.
Jack 5 is mainly by guide post, push rod to be moved up or down, thereby bottom bracket axle is ejected by push rod, and then saves staff's labour intensity.The Main Function of support pier 7 is support jack and positioning sleeve, and can avoid that length because of guide post is long causes guide post to fracture or bending.The Main Function of positioning sleeve is to prevent that guide post from shaking in the process of moving upward.The utility model is simple in structure, easy for installation, the labour intensity that can effectively reduce a staff.
The dual-side of described stator 10 is equipped with provision for disengagement 9.
The side of stator 10 can only arrange a set of provision for disengagement, arrange two cover provisions for disengagement can make staff convenient eject bottom bracket axle, but due to insufficient space, be not suitable for arranging three covers or more provision for disengagement.
Between described support pier 7 and jack 5, supporting seat 6 is installed.
