The utility model belongs to the technical field of
mechanical equipment, particularly relates to a jacking device for aligning a motor, and provides the following scheme aiming at the problems of troublesome and laborious crane matching operation and high
machine-team cost in the background technology: the jacking device comprises a spiral jacking
assembly and a height adjusting monitoring
assembly, the nut is welded on the outer wall of the top of the base. When the device is used, the nut is locked by a
wrench, and the ejector block is wrenched in the opposite direction by another
wrench, so that the jacking and falling of the motor can be realized, the device is convenient to use and small in occupied area, alignment jacking operation can be performed in a narrow space, a crane does not need to be matched for operation, the
machine-to-
machine cost of the crane is reduced, and the working efficiency of the crane is improved. The lifting of the top ring is realized through the rotation between the nut and the
threaded rod, so that the pointer at one end of the connecting rod can mark the scale line position on the scale plate in real time, the jacking and falling height of the motor in the narrow space can be accurately monitored, the labor efficiency is improved, and the popularization and use are facilitated.
