The utility model discloses can make things convenient for accurate location steam turbine baffle center.
Description
Technical field
The utility model relates to a kind of survey instrument, particularly a kind of partition board of steam turbine alignment instrument.
Background technology
Partition board of steam turbine and the adjustment of labyrinth casing Wa Wo center are important procedures in steam turbine installation and repairing, its construction quality is directly connected to the work efficiency of follow-up gap regudation of steam sealing, thus affect the thermal efficiency of unit, current each unit dividing plate and labyrinth casing are looked in time and quality have higher requirement, the method of present dividing plate alignment mainly contains method of testing shaft alignment and laser looks for middle method, measure the real center of dividing plate, both principles are identical, one is dummy shaft one is laser beam, and then use micrometer inside caliper or specific purpose tool to measure dividing plate two ends one by one, the distance of dummy shaft or laser beam is arrived in bottom, dummy shaft method has limitation in use procedure, unit difference needs to use different model dummy shaft, domestic current new-built unit does not all configure dummy shaft, the hollow nest of adjustment dividing plate cannot be measured in scene of causing, laser beam looks for middle method to use apparatus expensive, price is generally more than 1,000,000, and it is larger by such environmental effects in measurement data, as: temperature, wind speed etc.The data deviation that different personnel measure is also larger.
Summary of the invention
For the defect of prior art, the utility model provides a kind of partition board of steam turbine alignment instrument.
A kind of partition board of steam turbine alignment instrument, comprise base 1, described base 1 is provided with back-up block 2, described back-up block 2 is provided with rotating shaft 3, described rotating shaft 3 is through one end of cantilever 4, the other end of described cantilever 4 is provided with survey line Level tune screw rod 6, and the middle part of described cantilever 4 is provided with survey line vertical adjusting screw rod 5, and one end of described survey line Level tune screw rod 6 is provided with insulation roller 7.
Optionally, described survey line 10 is connected with balancing weight 12 by insulation roller 7.
Optionally, described survey line 10 is steel wire.
Optionally, described alignment instrument is installed on steam turbine 8 two ends by bearing.
The beneficial effects of the utility model are: use draw steel wire centering dividing plate Wa Wo center compensate for defect that dummy shaft method and laser look for middle method, cost is low, quick for installation, be suitable for all machine set types, but also it is identical with rotor bow to reach the rich degree of steel wire according to the natural bow adjustment steel wire counterweight of rotor, revise measuring error, with the obvious advantage compared with dummy shaft method, laser method.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model alignment instrument;
Fig. 2 is that installation diagram measured by the utility model alignment instrument;
Fig. 3 is the utility model centralized positioning measuring principle figure.
Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing, make above-mentioned and other object of the present utility model, Characteristics and advantages will be more clear.Reference numeral identical in whole accompanying drawing indicates identical part.Deliberately do not draw accompanying drawing in proportion, focus on purport of the present utility model is shown.
As shown in Figure 1, partition board of steam turbine alignment instrument of the present utility model comprises base 1, base 1 is provided with back-up block 2, back-up block 2 is provided with rotating shaft 3, rotating shaft 3 is through one end of cantilever 4, the other end of cantilever 4 is provided with survey line Level tune screw rod 6, cantilever 4 can 3 rotate around the shaft, and the middle part of cantilever 4 is provided with survey line vertical adjusting screw rod 5, and one end of Level tune screw rod 6 is provided with insulation roller 7, survey line 10 can be connected with balancing weight 12 by insulation roller 7, and survey line 10 can be steel wire.
Refer to Fig. 2, by bearing, alignment instrument can be installed to cylinder 8 split two ends during installation, survey line is suspended on the roller 7 of alignment instrument, and is connected with balancing weight 12, check survey line distance dividing plate 9 distance up and down by micrometer inside caliper 11.As shown in Figure 3, by shown in Fig. 3, wire 14 and earphone 15 are connected with power supply 13 during measurement, according to the hollow nest data of rotor, by adjustment vertical adjusting screw rod 5, Level tune screw rod 6 thus adjustment survey line steel wire 10 apart from dividing plate 9 distance up and down, steel wire is made to return to the hollow nest data of rotor.Use micrometer inside caliper 11 measuring steel wire to the distance in dividing plate 9 direction up and down, can obtain dividing plate center deviation difference, measurement numerical value gets earphone to be had current sound and is minimum value, and survey line position is just place, partition board of steam turbine center thus.
Set forth a lot of detail in the above description so that fully understand the utility model.But above description is only preferred embodiment of the present utility model, the utility model can be much different from alternate manner described here to implement, and therefore the utility model is not by the disclosed concrete restriction implemented above.Any those skilled in the art are not departing under technical solutions of the utility model ambit simultaneously, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Every content not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solutions of the utility model protection.
