Abstract
The general assembly and disassembly tools of turbo generator set seal assembly. At present, the power plant can only rely on the lifting hook of a travelling crane to drag through a steel wire rope in the process of assembling and disassembling the sealing bush seat, the oil baffle plate and the transition ring of the generator, and parts such as the sealing bush are positioned at the innermost positions of the end face of the generator, so that great pressure is brought to maintenance work, and the personal safety hazard and the equipment safety hazard are great. The utility model comprises the following steps: mobile jib (1), mobile jib one end is connected with two circular closure plates (2), and arc band iron (3) are connected to the other end, the arc band iron is convex, and it has a set of locating hole (4) to process on the arc band iron, the locating hole distributes according to the axis bilateral symmetry of mobile jib, the arc band iron passes through bolt and turbo generator set's seal assembly (5) and connects. The utility model is used for disassembling and assembling the sealing component of the steam turbine generator unit.
Description
Technical Field
The utility model particularly relates to a general disassembling tool for a sealing component of a steam turbine generator unit.
Background
The generator is one of three main units of turbo generator set, and the important parts of the generator such as the generator sealing bush seat, the oil baffle plate and the transition ring of the generator are disassembled in sequence in the overhaul process of the generator, and the generator sealing bush is arranged inside the end face of the generator in most of the generator sets at present, which brings great trouble to the overhaul work. Important parts of the generator, such as a sealing tile, influence the hydrogen leakage amount of the generator, and personal injury and equipment damage caused by collision in the process of disassembly and assembly are prevented.
At present the sealed tile seat of generator, keep off the oil board, the former extracting tool of transition ring is instrument at random, with the sealed tile seat of power plant's generator, keep off the oil board, the bolt hole and the arc surface of transition ring are not supporting, the power plant is carrying out the sealed tile seat of generator, keep off the oil board, the dismouting in-process of transition ring can only rely on the lifting hook of driving to pass through wire rope and pull, because parts such as sealed tile are in the position of generator terminal surface the inside most, this has brought very big pressure for maintenance work, the person is very big with equipment safety hidden danger, consequently need to provide a general assembly and disassembly tools of turbo generator set seal assembly urgently.
Disclosure of Invention
The utility model aims to provide a general disassembling tool for a sealing component of a steam turbine generator unit.
The above purpose is realized by the following technical scheme:
the utility model provides a general assembly and disassembly tools of turbo generator set seal assembly which constitutes and includes: the mobile jib, mobile jib one end is connected with two circular closure plates, and the arc band iron is connected to the other end, the arc band iron is convex, and it has a set of locating hole to process on the arc band iron, the locating hole distributes according to the axis bilateral symmetry of mobile jib, the arc band iron passes through bolt and turbo generator set's seal assembly and connects.
Has the advantages that:
the arc-shaped flat iron adopted by the utility model can be matched with the arc parts of the sealing bush seat, the oil baffle plate, the transition ring and the like, and the circular blocking plate is used for placing a steel wire rope for lifting, so that the steel wire rope is prevented from running in the moving process, the safety and the stability of maintenance work are improved, the probability of personal injury of maintenance personnel and equipment damage is reduced, the maintenance efficiency is improved, and the labor cost is saved. The utility model has simple structure, easy storage and no need of occupying large warehouse space.
Description of the drawings:
FIG. 1 is a schematic perspective view of the present invention;
FIG. 2 is a front view of the present invention;
FIG. 3 is a schematic view of the arcuate flat iron and seal assembly in combination;
in the figure: 1. a main rod; 2. a circular closure plate; 3. arc-shaped flat iron; 4. positioning holes; 5. and (7) sealing the assembly.
The specific implementation mode is as follows:
example 1:
a general assembly and disassembly tools of turbo generator unit seal assembly, it includes: the device comprises a main rod 1, wherein one end of the main rod is connected with two circular blocking plates 2, the distance between the two circular blocking plates is 150mm, the other end of the main rod is connected with an arc-shaped flat iron 3, the arc-shaped flat iron is arc-shaped, a group of positioning holes 4 are processed on the arc-shaped flat iron and are symmetrically distributed in the left and right direction according to the axis of the main rod, the arc-shaped flat iron is connected with a sealing assembly 5 of a turbo generator unit through bolts, and the sealing assembly comprises a sealing tile seat, an oil baffle plate and a transition ring;
the steel wire rope lifting device comprises arc-shaped flat irons (designed according to the radian of a sealing bush seat, an oil baffle plate and a transition ring), a main rod, circular blocking plates and the like, wherein the two circular blocking plates are welded through the main rod made of steel pipes, and the distance between the circular blocking plates is about 150mm and is used for placing a steel wire rope for lifting so as to prevent the steel wire rope from being out of position in the moving process; the arc-shaped flat iron is arranged on one circular blocking plate, the main rod is welded with the center of the arc-shaped flat iron (two symmetrical sides of the arc-shaped flat iron are provided with holes which are designed according to the actual site sealing tile seat, the oil baffle plate, the hole site distance of the transition ring bolt and the assembly radian among all parts respectively), wherein the distance between the circular blocking plate and the arc-shaped flat iron is larger than the distance between the position of the sealing tile and the end cover of the generator, otherwise, the circular blocking plate cannot be vertically lifted, and potential safety hazards of personnel and equipment exist; the main rod part outside another circular closure plate is used for personnel to control the direction and balance, when any one of the parts is disassembled and assembled, the disassembling and assembling tool can be fixed with the part by using the existing travelling crane and chain block of a production plant and disassembling 2-4 bolts of the part, and the safe disassembling and assembling of the sealing tile, the oil baffle plate and the transition ring of the generator can be realized without independently preparing special bolts.
