Specific embodiment
The core of the utility model is to provide a kind of lifting device of generator casing, is being lifted with solving generator casing
The problem of existing lifting and transhipment difficulty in the process.
In order to make those skilled in the art more fully understand technical solution provided by the utility model, below in conjunction with attached
The utility model is described in further detail with specific embodiment for figure.
As depicted in figs. 1 and 2, the lifting device of a kind of generator casing provided by the embodiment of the utility model, slinger
Tool includes connector sleeve 1, and one end of connector sleeve 1 is provided with the first inner bolt hole 11, and the inner bolt hole and generator of the first inner bolt hole 11
The external screw thread of the electrical joint of casing is adapted；The other end of connector sleeve 1 is provided with the second inner bolt hole 12, and the second inner bolt hole
12 internal screw thread with the stud of the hanging ring of lifting for being adapted.
Above-mentioned lifting device in actual use, is connected by the electrical joint of the first inner bolt hole and generator casing
It connects, the Stud connection of the second inner bolt hole and hanging ring, in the hoisting process that generator casing then can be realized by hoisting ring,
Since connector sleeve is only connect with the electrical joint of generator casing, this mode is assembled simply, facilitates operation, can be used for overhauling
The lifting of the spacious occasion such as workshop or experiment workshop solves generator casing and lifts and transport present in hoisting process and is stranded
Difficult problem.
In some specific embodiments, in order to enable hanging ring lift force during so that generator casing by
