Description
Technical field
The present invention relates to the dismounting field of flue gas turbine expander bearing box cover, more particularly to a kind of cigarette machine bearing case lid that is used for dismount
Horizontal equilibrium device and assembly and disassembly methods.
Background technology
In petrochemical industry, large-scale flue gas turbine expander overhauls due to being frequently necessary to, its bearing box cover also need accordingly through
Often open, in addition due to the needs of clearance measurement in maintenance process, bearing box cover is also required to carry out being dismounted for multiple times.But bearing
The major part of case lid needs the inside into flue gas turbine expander equipment when mounted, and the installing space of flue gas turbine expander outer casing inner wall is in interior
The horizontal semi-circular of narrow outer width is cone-shaped, and installing space is narrow and small, and case lid weighs about 900 ㎏ certainly in addition, therefore can not pass through artificial lift to move
It is directly in place.
Traditional installation method is：The first suspension centre and the second suspension centre of installation are provided with bearing box cover, passes through steel wire
After rope directly bundlees, vertical jack is sling, then in place by the traction of horizontal jack.But due to the bearing housing of final on-station position
The center of gravity of lid can not set suspension centre in device interior, and because installation environment limits above the center of gravity of final on-station position, in order to
Making bearing box cover smoothly install to also need to extra more people and carry out pulling the manual operation such as lift, installing space is narrow, is not easy to construct,
Therefore it is above-mentioned it is this directly lifted using jack steel wire rope, by dragging could accurately method in place be not only time-consuming takes
Power, and bearing box cover can not keep level completely it is in place, easily damage the part such as bearing and bearing box cover sealing surface, in addition can
Increase the error of measurement data.
The content of the invention
In order to solve above-mentioned the deficiencies in the prior art, present invention offer is a kind of to be used for what cigarette machine bearing case lid dismounted
