Embodiment Construction

[0017] The tool and method for measuring the swing of the suspension shaft of a turbogenerator set according to the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 , figure 2 As shown, the suspension shaft swing measurement tool of the steam turbine generator set in this embodiment includes a support frame 1, a ball pressing plate 2, a ball support 3, a ball 4, a ball base 5, a swing frame base 6, an adjustment screw 9, an adjustment Nut 10 and floating hanging tile 8: pull the floating hanging tile 8 through the adjusting screw 9 to lift the rotor, and under the protection of the floating hanging tile 8, turn out the bearing bush of the bearing seat; Fall to the original position; at this time, the force of the rotor is distributed to the four ball pressing plates 2 through the two supporting frames 1 at the front and rear of the rotor. The ball pressing plates 2 are located on the ...

Abstract

The invention belongs to the technical field of steam turbine generating set researching, and particularly relates to a tool and a method for measuring throw of a steam turbine generating set hanger.According to the tool and the method of the invention, a rotor is lifted through dragging a floating bearing by an adjusting screw. Through protection of the floating bearing, a bearing bush of a bearing seat is turned to outside. After the bearing bush is turned to outside, the rotor falls to an original position through the adjusting screw. Hereon, a force which is bear by the rotor is distributed to four ball pressing plates through two supporting frames in front of and behind the rotor. The ball pressing plates are arranged on balls of a ball bracket and can freely slide in a planar direction for simulating a no-resistance free state of the rotor. A bearing bush turning process and a measuring process are carried out through protection of the two floating bearings. The tool and the method settle technical problems of high measurement error and low operation safety in prior art. Furthermore the tool and the method have advantages of remarkably improving measuring precision, reducingtime in an operation step and measurement, and ensuring safety of equipment and an operator.

Description

technical field [0001] The invention belongs to the technical field of research on steam turbine generator sets, and in particular relates to a measuring tool and method for the swing of a suspension shaft of a steam turbine generator set. Background technique [0002] The difficulty in measuring the swing angle of the rotor suspension shaft of the turbogenerator is to simulate the free suspension state of the rotor and overcome the swing resistance of the rotor. [0003] The traditional swing measurement of the suspension shaft uses a crane hook or bracket to pull the rotor through a wire rope. This method must use a wire rope. The elastic deformation and traction of the wire rope will affect the free state of the rotor, resulting in measurement errors. In addition, the traditional measuring tools cannot be used for the rotor overturning operation. Before installing the bracket, the rotor overturning operation must be performed first. During this period, the rotor has no re...
