Turbine rotator overturning hoist device

Abstract

The invention provides a turbine rotator overturning hoist device. The hoist device is characterized by comprises a hoisting arm, a hoisting disc, a clamping block and an adjusting mechanism; the hoisting disc comprises a first disc surface side and a second disc surface side on the axial direction; the hoisting arm is hinged to the hoisting disc on the first disc surface side; the hoisting disc is provide with a hoisting disc clamping surface on the second disc surface side; the clamping block is connected with the hoisting disc on the second disc surface side; the clamping block is providedwith a clamping surface; the clamping block is arranged in a mode of being movable between the first position and the second position; the clamping block is closer to the hoisting disc at the second position relative to the first position; the adjusting mechanism is connected with the clamping block and comprises an extruding part which extrudes out of the first disc surface side; and the clampingblock is adjusted to move between the first position and the second position by the extruding part of the adjusting mechanism. The turbine rotator overturning hoist device can be convenient for hoisting operation of a turbine rotator assembly.

Description

technical field [0001] The invention relates to a turbine rotor turning hanger for hoisting a turbine rotor assembly. Background technique [0002] During the assembly process of the turbine rotor assembly, such as the high-pressure turbine rotor assembly, the turbine rotor assembly needs to be hoisted. The existing front-end hanger usually adopts a disc structure and is installed in front of the drum shaft of the turbine rotor assembly through bolts and nuts. On the side, because the installation side is the inner side, when installing the bolts, it is necessary to put the bolts into the drum shaft through the open holes on the disc, and pass from the inside to the outside of the installation side. When removing the bolts, it is necessary to pass through the open holes from the installation Fix the bolts on the inside of the side and loosen the nuts. Due to the narrow space, the operation is inconvenient, the work efficiency is low, and the bolts fall into the drum shaft to...

[0002] During the assembly process of the turbine rotor assembly, such as the high-pressure turbine rotor assembly, the turbine rotor assembly needs to be hoisted. The existing front-end hanger usually adopts a disc structure and is installed in front of the drum shaft of the turbine rotor assembly through bolts and nuts. On the side, because the installation side is the inner side, when installing the bolts, it is necessary to put the bolts into the drum shaft through the open holes on the disc, and pass from the inside to the outside of the installation side. When removing the bolts, it is necessary to pass through the open holes from the installation Fix the bolts on the inside of the side and loosen the nuts. Due to the narrow space, the operation is inconvenient, the work efficiency is low, and the bolts fall into the drum shaft to cause a greater risk of parts colliding.
