Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of guide vane lever, especially relates to a kind of hydraulic turbine generator guide vane lever.
Background technique
Guide vanes of water turbine mechanism is the indispensable structure of a cover in the hydraulic generator unit, and it is to be used for regulating the vitals that enters the rotary wheel of water turbine flow with controlled water flow.The traditional guide vanes of water turbine and the Connecting format of guide vane lever are that stator is fixed in the sleeve of outer gate barrel, and guide vane lever is sleeved on axle and axle on guide vane lever and the stator is fixing by jackscrew on the stator, and the sleeve upper end installs end cap by bolt.This means of fixation is the linkage structure complexity not only, nor quick detachable and installation has also increased production cost.
For this reason, people are by constantly being to improve and innovation, row as, in relevant document, a kind of guide vane lever structure [ZL:200520031571 was once disclosed; CN:2830564Y], its main characteristics comprises, guide vane lever, guide vane lever is provided with mounting arm, guide vane lever one side has the arm body that clearance groove connects guide vane lever, the outer surface of the guide vane lever of clearance groove both sides respectively has a concave station, has 1 or more than one mounting hole on the concave station, and cross-under has link that the guide vane lever arm body of clearance groove both sides is linked together in the mounting hole.It solves existing in prior technology when unit carries out large repairs, particularly guide vane lever and entrance bucket shaft head corrosion are more serious, dismantlement work to the water distributor assembling is made troubles, in unloading process, both expend great amount of manpower and material resources, taken the technical problem of a large amount of maintenance quality time etc. again.
Though such scheme has solved dismantlement work technical problem such as make troubles, and has simplified the structure of guide vane lever part simultaneously to a certain extent, the technical problems such as connection complexity of present guide vane lever still exist.
Summary of the invention
The purpose of this utility model is at the problems referred to above, the guide vane lever of provide a kind of compact structure, being convenient to connect.
For achieving the above object, the utility model has adopted following technical proposal: a kind of hydraulic turbine generator guide vane lever, comprise the main body that tubular is hollow, the surface of described main body is connected with mounting arm, the other end of this mounting arm is connected with accessory body, it is characterized in that, be provided with keyway in the described hollow main body, end face is provided with several and is convenient to lift by crane tapped hole when dismounting or installation.
In above-mentioned a kind of hydraulic turbine generator guide vane lever, described Keyway Section is triangular in shape.
In above-mentioned a kind of hydraulic turbine generator guide vane lever, described tapped hole has two.
Compared with prior art, this hydraulic turbine generator guide vane lever advantage is:
1, owing in the technical program, be provided with keyway in the main body, is convenient to realize the transmission of guide vane lever main body.
2, the tapped hole that is provided with of main body end face, when dismounting or install when needing lifting, by other nut be threaded, can realize that so just its lifting is convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Among the figure, 1, main body; 2, mounting arm; 3, accessory body; 4, keyway; 5, tapped hole.
Embodiment
As shown in Figure 1, 2, a kind of hydraulic turbine generator guide vane lever, comprise the hollow main body of tubular 1, the surface of described main body 1 is connected with mounting arm 2, the other end of this mounting arm 2 is connected with accessory body 3, it is characterized in that, is provided with keyway 4 in the described hollow main body 1, owing to be provided with keyway 4 in the main body 1, be convenient to realize the transmission of guide vane lever main body 1.Described keyway 4 cross sections are triangular in shape.This triangle is an equilateral triangle.
End face is provided with several and is convenient to lift by crane tapped hole 5 when dismounting or when installing, the tapped hole 5 that main body 1 end face is provided with, when dismounting or install when needing lifting, by other nut be threaded, can realize that so just its lifting is convenient.In the technical program, tapped hole 5 has two.
