Abstract
The utility model relates to a measuring device for outer corner of a guide blade arm; the utility model is characterized in that the utility model comprises a guide finger fixedly arranged on an excircle of an exterior admission water ring, wherein the end part of the guide finger just points to the shaft center of articulated shafts of two link arms. The utility model has the advantages of convenient measurement, simple structure and easy use, and can relatively accurately measure the outer corner of the guide blade arm and improve the assembling precision of the guide blade.
Description
Technical field
The utility model relates to the assembling of stator in the hydrogenerator through-flow machine set water guiding mechanism, particularly measures the device of guide vane lever corner.
Background technology
To carry out the test of stator degree of drawing back after water distributor assembling is at present finished, need actual measurement guide vane opening and guide vane lever corner size, whether conform to designing requirement with the full stroke of determining servomotor.And the guide vane lever corner is a bulk, and the measurement of guide vane opening was only carried out in bad measurement in the past.The assembling effect is bad like this, and error is bigger.
Summary of the invention
The utility model provides a kind of device that can measure the guide vane lever corner for solving the technical matters that exists in the known technology more accurately
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of device of measuring the guide vane lever corner, comprise the pointer that is packed on the outer gate barrel cylindrical, the end of described pointer just in time refers on the axle center of the jointed shaft of two pitman arms.
Advantage and the good effect that the utlity model has are: the utility model is measured convenient, and is simple, can measure the corner of guide vane lever more accurately.
Description of drawings
Fig. 1 is a pointer synoptic diagram of the present utility model;
Fig. 2 is the synoptic diagram that the utility model is implemented.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, Fig. 2, the utility model comprises the pointer 1 that is packed on the outer gate barrel cylindrical, and the end of described pointer 1 just in time refers on the axle center of the jointed shaft 2 of two pitman arms.
See also Fig. 2, the stator 3 of the hydraulic turbine is installed between outer gate barrel 4 and the interior admission water ring 5, and the folding angle of stator 3 will be adjusted according to the size of generated output.The spindle nose of stator 3 and guide vane lever 9, connecting plate 7 is affixed, connecting plate 7 is hinged by jointed shaft 2 with connecting rod 11, connecting rod 11 is hinged with control loop 6, drive two connecting rods by control loop 6, thereby driving stator rotates, because the utility model has adopted on the outer gate barrel cylindrical and has installed pointer, the end of pointer just in time refers on the axle center of the jointed shaft of pitman arm, when control loop drives the stator rotation by two bar linkage structures, the position of the jointed shaft of two connecting rods changes, and the end of pointer is fixed, measure the distance of the position in its corresponding jointed shaft axle center, each pointer end, by comparing and measuring the result, can learn the consistance situation of guide vane lever corner, and then adjust the rigging position of stator.It is convenient, simple to measure, and can measure the corner of guide vane lever more accurately, improves the assembly precision of stator.
Claims (1)
1. device of measuring the guide vane lever corner, it is characterized in that: comprise the pointer that is packed on the outer gate barrel cylindrical, the end of described pointer just in time refers on the axle center of the jointed shaft of two pitman arms.
