Scope is wide, substantially increases work efficiency and certainty of measurement.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state figure of the present utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.A kind of turbine rotor alignment as shown in Figure 1
Frame table instrument, including cylindrical holder 1, is provided with frame table bar 2 in one end of cylindrical holder 1, the other end is provided with rotor couplings and fixes
Device, described rotor couplings fixing device is by fixing tapered retention members 3, activity tapered retention members 4 and 5 groups of position and lock part
Become, described fixed positioning piece 3 and activity orientation part 4 are shape size identical tapered retention members, a diameter of 35- of its osculum
40mm, a diameter of 100-120mm of big mouth, disclosure satisfy that the alignment demand of 35～100mm coupling bolt diameter.Described fixation
Tapered retention members 3 fixation is set on cylindrical holder 1, and described fixed positioning piece 4 is more than rotor connection with the distance of position and lock part 5
Connect the thickness of device 6, can conveniently install, and can be locked by position and lock part 5 after installation；Described activity tapered retention members 4
It is movably set on cylindrical holder 1, and the osculum of two tapered retention members is relatively, activity tapered retention members 4 can be along cylindrical holder 1
The distance between mobile regulation two keepers, and pass through position and lock part 5 locking positioning.
As shown in figure 1, described position and lock part 5 is by regulating bolt 5-1, locking nut 5-2 and lock washer 5-3 group
Become, regulating bolt 5-1 one end is fixedly connected with cylindrical holder 1, described lock washer 5-3 is arranged on activity orientation part 4 and locking
Between nut 5-2.
When this utility model uses, as shown in Fig. 2 by the frame table end of this utility model cylindrical holder 1 from wherein side
The screw of shaft coupling 6 passes through, and the other end passes from the corresponding screw of the shaft coupling 6 of opposite side, and then regulation activity taper is fixed
Position part 4, by shaft coupling clamping, is locked finally by position and lock part 5.Generally in rotor of turbogenerator set shaft coupling alignment
During, side shaft coupling screw sets up 3 groups of this devices, then by 2 tables of dehiscing (being arranged symmetrically), 1 circumference table divides
It is not arranged on the frame table bar 2 of this device.After the completion of erection, rotate 360 degrees just can precisely measure out two rotors center inclined
Difference value, thus meet steam turbine installation accuracy and prescription.
This utility model can meet the coupling bolt of different-diameter size by two tapered retention members, thus
Ensure that the steam turbine of various models all can adopt this device.
