Abstract
The utility model discloses a kind of portable scraping teeth auxiliary devices, it is characterized in that, including two brackets, one end of two brackets is separately fixed at the two sides of angle grinder, the other end of two brackets is equipped with the dedicated grinding that can be equipped between the guide wheel that resistance vapour on piece rolls, two guide wheels for the cutting resistance vapour piece tooth tip that rubs.Device provided by the utility model overcomes the deficiencies in the prior art, and structure is simple, easy to install and use.Inner cylinder need not be returned factory when maintenance, need only construct at the scene can be realized maintenance purpose, reduce maintenance cost；Adaptation to local conditions has saved the repair time；Portable design saves space for maintenance for scene, operator is facilitated to operate；Live process velocity is fast, can determine the ideal gap of resistance vapour pieces at different levels, improve the efficiency of steam turbine, under the premise of guaranteeing unit safety operation, reduces steam leakage, reduces coal consumption for power generation.
Description
Technical field
The utility model relates to a kind of mechanical structure more particularly to a kind of portable scraping teeth auxiliary devices, belong to steam turbine
It hinders vapour piece and adjusts field.
Background technique
Resistance vapour piece is the important component of Turbine seal, and effect is to reduce steam leakage, reduces idle work, improves
Unit efficiency achieves energy-saving and emission reduction purposes.
Currently, steam turbine resistance the main types of presentation of vapour piece be it is inserted, the mesh of sealing is realized by way of throttling expansion
's.Under normal circumstances, power plant do not have processing resistance vapour piece ability, therefore inlay resistance vapour piece part need to return steam turbine plant replacement,
Processing.Its is costly, and the turnaround time is long, and scene still needs to adjust gap again, and the adjustment of resistance vapour piece gap directly affects
Unit thermal effect.
Summary of the invention
Technical problem to be solved by the utility model is: solving the problems, such as how rapid field maintenance hinders vapour piece.
In order to solve the above-mentioned technical problem, there is provided a kind of portable scraping teeth auxiliary dresses for the technical solution of the utility model
Set, which is characterized in that including two brackets, one end of two brackets is separately fixed at the two sides of angle grinder, two brackets it is another
One end is equipped with one and can be equipped between the guide wheel that resistance vapour on piece rolls, two guide wheels for the cutting resistance vapour piece tooth tip that rubs
Dedicated grinding.
Preferably, the bracket is bolted on original handle bolt hole of angle grinder.
Preferably, when the peak contact of the dedicated grinding and resistance vapour piece, the distance between guide wheel and resistance vapour piece are
0.2-0.6mm。
Device provided by the utility model overcomes the deficiencies in the prior art, and structure is simple, easy to install and use.Maintenance
When inner cylinder need not be returned factory, need only construct at the scene can be realized maintenance purpose, reduce maintenance cost；Because of ground system
Preferably, the repair time has been saved；Portable design saves space for maintenance for scene, operator is facilitated to operate；Live process velocity
Fastly, the ideal gap that can determine resistance vapour pieces at different levels, improves the efficiency of steam turbine, in the premise for guaranteeing unit safety operation
Under, reduce steam leakage, reduce coal consumption for power generation.

Fig. 1 is a kind of usage state diagram of portable scraping teeth auxiliary device；
Fig. 2 is the connection schematic diagram of dedicated grinding with resistance vapour piece；
Fig. 3 is a kind of side view of portable scraping teeth auxiliary device.
Specific embodiment
To be clearer and more comprehensible the utility model, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
Embodiment 1
The utility model is a kind of portable scraping teeth auxiliary device, can repair in Overhaul site completion resistance vapour piece and scrape work,
As shown in Figure 1, Figure 3 comprising two guide wheels, 1, two bracket 2.One end of two brackets 2 is separately fixed at the two of angle grinder 3
Side, the other end of two brackets 2 are equipped with the guide wheel 2 that can be rolled on resistance vapour piece 5, are equipped with and use between two guide wheels 2
The dedicated grinding 4 of resistance 5 tooth tip of vapour piece is cut in friction.
The utility model utilizes the original handle bolt hole of angle grinder 3, and bracket 2 is fixed in angle grinder 3 with bolt, such as schemes
Shown in 1, when work, guide wheel 1 is ridden on the tooth tip of resistance vapour piece 5.As shown in Fig. 2, working as the tooth tip that guide wheel 1 rides with hinders vapour piece 5
When upper, the peak contact of dedicated grinding 4 and resistance vapour piece 5 carries out friction cutting to achieve the purpose that scraping teeth.Pass through design, guide wheel 1
Dimension data to may be implemented to fix scraping teeth amount every time be 0.2mm, i.e., when dedicated grinding 4 and the peak contact of resistance vapour piece 5, lead
The distance between wheel 1 and resistance vapour piece 5 are 0.2mm.
Embodiment 2
In the present embodiment, the dimension data of guide wheel 1 may be implemented to fix scraping teeth amount every time to be 0.6mm, i.e., when dedicated grinding 4
When with the peak contact of resistance vapour piece 5, guide wheel 1 and resistance the distance between vapour piece 5 are 0.6mm.
Other are same as Example 1.
