Abstract
The invention discloses a guide vane arm which comprises a guide vane arm main body and a mounting arm connected with the guide vane arm main body. A through opening is arranged on one side, away from the mounting arm, of the guide vane arm body, the guide vane arm main body at the opening end is provided with an outwards-protruding boss respectively, at least two threaded holes are formed in the boss, a rubber sealing pad used for sealing the opening is arranged on the inner side of the guide vane arm main body, and a plurality of mounting holes used for lifting are uniformly formed on the periphery of the top of the guide vane arm main body. After adopting the above structure, when replacement of a guide vane shaft head or the guide vane arm main body is needed during maintenance or fault, a user only needs to loosen bolts in the threaded holes in the boss and then enable a crane to be inserted into the mounting holes to lift the guide vane arm main body. During mounting, the user only needs to fill the rubber sealing pad at the opening well, enable the crane to be inserted into the mounting holes to mount the guide vane arm main body on the guide vane shaft head in a sleeved manner and fasten the bolts in the threaded holes, so that convenience in mounting and demounting is realized.
Description
Technical field
The present invention relates to a kind of component of hydraulic turbine generator water distributor, particularly a kind of guide vane lever.
Background technique
Guide vane lever is an important transmission part of hydraulic turbine generator, and guide vane lever main body is generally whole tube-in-tube structure, and this tube-in-tube structure is sleeved on entrance bucket shaft head, controls and leads leaf divergence.Because stator and the guide vane lever of every water turbine all has several, once one of them or several breaking down, when needing maintenance or changing, because of corrosion or cooperation tension etc., the sleeve of out of order guide vane lever need to be destroyed and cuts and come, again guide vane lever is taken off from entrance bucket shaft head, very inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provides a kind of simple in structure, dismounting, guide vane lever easy for installation.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of guide vane lever, comprise guide vane lever main body and connected mounting arm, described guide vane lever main body is provided with the opening of perforation away from a side of mounting arm, the guide vane lever main body of this opening end is respectively arranged with the boss of projection laterally, on this boss, be provided with at least two tapped holes, described guide vane lever main body inner side is provided with the rubber gasket in order to shutoff opening, is evenly provided with several in order to the mounting hole of lifting in described guide vane lever main body top circumference.
Described rubber gasket is Y type rubber gasket.
Described mounting hole is 4.
The present invention adopts after said structure, when overhauling or fault need to change entrance bucket shaft head or guide vane lever main body, only need unclamp the bolt in boss upper screwed hole, and recycling turned crane inserts in mounting hole, the guide vane lever main body of slinging.During installation, first at the populated rubber gasket of opening, recycling turned crane inserts in mounting hole, guide vane lever main body is sleeved on entrance bucket shaft head to the bolt of fastening screw pit, thereby installation, convenient disassembly.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of guide vane lever of the present invention.
Wherein have: 1. guide vane lever main body; 2. mounting arm; 3. opening; 4. boss; 5. tapped hole; 6. rubber gasket; 7. mounting hole.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation with concrete better embodiment.
As shown in Figure 1, a kind of guide vane lever, comprise guide vane lever main body 1 and connected mounting arm 2, described guide vane lever main body 1 is provided with the opening 3 of perforation away from a side of mounting arm 2, the guide vane lever main body 1 of these opening 3 ends is respectively arranged with the boss 4 of projection laterally, on this boss 4, be provided with at least two tapped holes 5, described guide vane lever main body 1 inner side is provided with the rubber gasket 6 in order to shutoff opening 3, be preferably Y type rubber gasket, in described guide vane lever main body 1 top circumference, be evenly provided with 4 in order to the mounting hole 7 of lifting, this mounting hole 7 also can be 2, 6 or a plurality of.
When overhauling or fault need to change entrance bucket shaft head or guide vane lever main body 1, only need unclamp the bolt in boss 4 upper screwed holes 5, now, opening 3 supports are large, and entrance bucket shaft head fluffed with coordinating of guide vane lever main body 1, was convenient to the dismounting of guide vane lever main body 1.If desired, also Y type rubber gasket can be scratched with cutting tool; The abutting end of rear recycling turned crane inserts in mounting hole 7, the guide vane lever main body 1 of slinging.During installation, need first at the opening 3 populated rubber gaskets 6 in place, recycling turned crane inserts in mounting hole 7, guide vane lever main body 1 is sleeved on entrance bucket shaft head to the bolt of fastening screw pit 5, thereby installation, convenient disassembly.
