It is bad, this thing, it is necessary to which barring gear rotates several circles to motor shaft, to judge the load (the i.e. machinery or transmission that are driven by motor shaft
Part) whether there is stuck situation, from without damaging showing for motor (burning out) because the startup load of motor becomes greatly
As.
Utility model content
Technical problem to be solved in the utility model is the defects of overcoming prior art, there is provided a kind of gas turbine jiggering
Device, it can reach the phenomenon for checking motor shaft whether there is jam, so as to avoid because gas turbine is parked for a long time, or not start shooting
Directly initiate the phenomenon for causing generator and gas turbine to damage.
The utility model solves above-mentioned technical problem and adopted the technical scheme that：A kind of gas turbine jiggering device, it is wrapped
Include：
Axis hole connector, the axis hole of insertion axle and radially distensible or shrink is provided with the top of the axis hole connector
Seam portion；
Guiding connector, the guiding connector are inserted on axis hole connector, and the axis hole connector can led
Moved axially on to connector, the top of the guiding connector is provided with the enlarged portion coordinated with seam portion, when relative to institute
When stating the guiding connector axial movement axis hole connector, the enlarged portion acts on the seam portion, makes seam portion radially
Expansion is shunk.
Further, it is provided with expansion slot along its axial direction on the perisporium in the seam portion.
Further, the enlarged portion is the frustum being arranged on guiding connector.
Further, screw thread figure is provided with the guiding connector.
Further for the promotion axis hole connector, and make seam portion radial dilatation or contraction, gas turbine jiggering dress
Putting also includes axial limiting locking nut, and the axial limiting locking nut is threadedly attached on screw thread figure, and institute
State together with axial limiting locking nut is against with the axis hole connector, by rotating the axial limiting on guiding connector
Locking nut, so as to promote the axis hole connector to be moved axially on guiding connector.
Whole overall further for rotation, so as to reach the purpose of spin motor shaft, gas turbine jiggering device also wraps
Include and be connected and be used for the overall handle that rotary steering connector and axis hole connector are assembled with the guiding connector.
Further, the handle is through on guiding connector, and the handle be threadedly attached in it is tight on handle
Determine screw to be locked together with the guiding connector.
Further, the screw thread figure of the guiding connector has also been connected through a screw thread nut in the bottom of handle.
After employing above-mentioned technical proposal, first seam portion is positioned in the axis hole of motor shaft, tightens axial limiting locking
Nut, because the effect of axial force makes the external diameter in seam portion become big, increasing friction force reaches the purpose coupled with motor shaft, rotation
Handle, motor shaft is rotated, play the purpose for checking for jam.
Brief description of the drawings
Fig. 1 is the assembling explosive view of gas turbine jiggering device of the present utility model.
Embodiment
