Embodiment Construction

[0016] Further detailed explanation through specific implementation mode below:

[0017] The reference signs in the drawings of the description include: upper beam 1 , vertical beam 2 , lower beam 3 , section steel 4 , upper lifting lug 5 , and lower lifting lug 6 .

[0018] Such as figure 1 As shown, a steam turbine bearing bush hoisting tool includes an upper beam 1, a lower beam 3, and a vertical beam 2 connecting and fixing the upper beam 1 and the lower beam 3. The upper beam 1 is provided with an upper lug 5, and the lower beam 3 is provided with a lower beam. The spacing between the lifting lug 6, the upper beam 1 and the lower beam 3 is greater than the diameter of the steam guide pipe. Specifically, the spacing can be 2-3 times the diameter of the steam guide tube. In this embodiment, the spacing can be Twice the diameter of the steam pipe.

[0019] The upper beam 1 and the lower beam 3 are parallel to each other and perpendicular to the vertical beam 2 . Such arra...

Abstract

The invention relates to the technical field of maintenance and hoisting of steam turbines, and particularly discloses a hoisting tool for a bearing bush of a steam turbine. The hoisting tool for thebearing bush of the steam turbine comprises an upper cross beam, a lower cross beam and a vertical beam, wherein the upper cross beam and the lower cross beam are connected and fixed by the vertical beam; an upper hoisting lug is arranged on the outer side of the upper cross beam; a lower hoisting lug is arranged on the outer side of the lower cross beam; and the distance between the upper cross beam and the lower cross beam is greater than the diameter of a steam guiding pipe. The problem that the steam guiding pipe needs to be disassembled for overhauling and hoisting a bearing below the steam guiding pipe can be effectively solved, operations such as overhauling and hoisting of the bearing below the steam guiding pipe can be carried out without disassembling the steam guiding pipe, theworkload is reduced, the overhauling time is shortened, and the overhauling cost is saved.

Description

technical field [0001] The invention relates to the technical field of steam turbine maintenance and hoisting. Background technique [0002] The rear bearing of the high and medium pressure cylinder and the front bearing of the low pressure cylinder are installed under the steam guide pipe from the high and medium pressure cylinder to the low pressure cylinder of the steam turbine. The bearing disassembly and maintenance here requires the removal of the steam guide pipe directly above to facilitate the lifting and maintenance of the vehicle, which greatly increases the workload and maintenance time, resulting in an increase in maintenance costs. Contents of the invention [0003] The object of the present invention is to provide a steam turbine bearing pad hoisting tool to solve the problem that the steam guide tube needs to be removed for maintenance and hoisting of the bearing below the steam guide tube. [0004] In order to achieve the above purpose, the basic solution...
