The device comprises a pedestal installed on the rotor, the pedestal is equipped with a rotation center body, the rotation center body is provided with a main shaft assembly, the main shaft assembly is connected with a weighing arm and a measuring arm respectively through tension devices, and the measuring arm is used for rotatably measuring the roundness through the rotation center body. The device is easy to install and easy to adjust concentricity, measurement is accurate, and accuracy and working efficiency of measuring the roundness of the rotor can be largely improved.
Description
Technical field
A kind of Large Hydroelectric Set rotor of the utility model is surveyed round belting, is applicable to the measurement of all kinds of large rotor circularity.
Background technology
During water wheels unit is installed and overhauled, it is an indispensable part that rotor roundness is measured with adjustment.Whether balance of electromagnetic force when rotor roundness is related to unit operation, this will directly affect the stability of unit operation.Rotor roundness accuracy requirement is high, and hydraulic turbine group rotor radius reaches several meters conventionally, and accuracy requirement is only 0.1mm level, therefore rotor roundness is measured to technique and has proposed very high requirement.
At present, though surveying round belting, traditional hydraulic turbine group rotor can realize rotor survey circle, but in measurement and installation process, there is following drawback: 1), adjust difficulty with the concentricity of rotor, traditional survey round belting often needs to set up asks heart device, utilize piano wire to find the center of the upper and lower anchor ring of rotor center part, adjust again the concentricity of surveying round belting and rotor, one asks heart device to set up complexity, measuring center is comparatively loaded down with trivial details, two survey round belting adjust time, method is limited, often needs repeated measurement and adjustment.2), self debug difficulties, due to the nearly 10m of large rotor radius, it is longer that rotor is surveyed the sounding rod of round belting own, needs to adjust its balance, guarantee its stability, and it is loaded down with trivial details without counterweight generally to survey round belting, precision is not high.3), base is without stationary installation, swing bearing precision is not high, thereby causes measuring accuracy not high, error is larger.
Summary of the invention
For overcoming above-mentioned technical disadvantages, the utility model provides a kind of Large Hydroelectric Set rotor to survey round belting, and this device installation is simple, concentricity adjustment is easy, measures precisely, improves greatly rotor and surveys round accuracy and work efficiency.
The technical scheme that the utility model is taked is: a kind of Large Hydroelectric Set rotor is surveyed round belting, comprise and be arranged on epitrochanterian base, centre of gyration body is installed on described base, described centre of gyration body is provided with spindle assemblies, described spindle assemblies connects weight arm, gage beam by take-up device respectively, and described gage beam is rotated and is surveyed circle by centre of gyration body.
Described base is provided with adjusts bolt group and hold-down bolt.Described weight arm, gage beam all adopt rectangular steel pipe to be made.Described centre of gyration body is bearing arrangement.Described weight arm is provided with balancing weight.
Described spindle assemblies is provided with dial gauge.Described gage beam is provided with dial gauge or laser range finder.
A kind of Large Hydroelectric Set rotor of the utility model is surveyed round belting, and its beneficial effect is as follows:
A kind of Large Hydroelectric Set rotor of the utility model is surveyed round belting, base designs adjustment bolt group, by adjusting bolt, carry out easily the concentricity adjustment of itself and rotor.Spindle assemblies is installed dial gauge, can measure the concentricity of this device and rotor center part, has avoided utilizing and has asked heart device to obtain the complicated processes of adjusting again survey round belting concentricity behind rotor center part center.
Gage beam and weight arm all adopt concrete filled rectangular steel tube members, and rigidity is large.Weight arm adopts balancing weight, and counterweight is convenient, can significantly improve and survey round belting resistance to overturning.After gage beam, weight arm are connected with centre of gyration body, utilize take-up device further to guarantee the levelness of gage beam, guarantee the stability of this survey round belting entirety.Described gage beam is provided with dial gauge or laser range finder.While adopting laser range finder, measuring speed is more accurate sooner, greatly improves rotor and surveys round work efficiency.
