Specific embodiment
The utility model is described further below in conjunction with drawings and examples.
As shown in Fig. 1 to 5, the utility model provides a kind of generator maintenance shift unit, including horizontal alignment structure
1, altitude calibration structure, rail and railcar 4.Wherein, the altitude calibration structure is separately mounted to generator 5 by fastener
Quadrangle, the rail and 4 structure of railcar cooperate, and the railcar 4 is movably mounted on rail.The rail and level
Calibration structure 1 is embedded in 5 civil engineering platform of generator；
The altitude calibration structure includes jacking bracket 2 and hydraulic jack 3, totally four groups of jacking bracket 2, is installed on
5 stator cage quadrangle of generator, is fixed by bolts on 5 casing of generator and footing piece 52, hydraulic jack 3 is placed in support
Underface, the bottom surface of the jacking bracket 2 are provided with the Support with the cooperation of the piston rod construction of hydraulic jack 3.
The Support that 2 lower end surface of jacking bracket is acted on by hydraulic jack 3 is cooperated by hydraulic jack 3, will
Generator 5 jacks up certain altitude, and railcar 4 is then slid into 5 lower part of generator, falls on generator 5 to railcar 4, passes through
Railcar 4 is pulled, laterally skids off certain distance together with generator 5, to meet the space requirement for taking out dress 5 rotor of generator.
It is four groups that the horizontal alignment structure 1, which is divided, and every group of horizontal alignment structure 1 includes two horizontal alignment monomers, every group
Horizontal alignment structure 1 is located at four angular zones of 5 bottom plate of generator.
The horizontal alignment monomer is located at the outside of two sides of four angular zones of affiliated 5 bottom plate of generator.
The horizontal alignment structure 1 includes adjusting bolt 11, adjusting nut 12 and support base 13, and the adjusting bolt 11 is by adjusting spiral shell
Mother 12 is mounted on support base 13.
After generator 5 is transported back and is dropped down onto basic civil engineering by railcar 4, since horizontal alignment structure 1 has shifted to an earlier date in place,
Pre- dropping place is set to be deteriorated less with initial position, then by the adjusting nut on rotation horizontal alignment monomer, controls adjustment bolt
Stroke, generator 5 is finely adjusted in transverse direction, vertical direction.In short transverse, the row of control jack can be passed through
Journey carries out axial spotting.
