In physics, moment of torsion is exactly the moment that object is rotated, and its size equals the product of the power and the arm of force.Moment of torsion is the important process parameter of plant equipment, and it has reflected plant equipment ability to work within the specific limits.Torque-measuring apparatus can be used as the on-line measurement device of plant equipment, is used for the function such as real time monitoring, control to equipment; If can measure the torque value of equipment accurately, reliably, easily, also can be used for fault diagnosis, improve aspect such as equipment performance.Therefore, torque measurement has become an important component part in the mechanical value measuring.
The method of torque measurement has a variety of, also has different torque measuring methods at the plant equipment of different model, and the torque parameter general using lever principle of large rotating machinery equipment such as rotary drilling rig is measured, referring to Fig. 1.Fig. 1 is a kind of typical torque-measuring apparatus.
Torque-measuring apparatus shown in Figure 1 mainly is made up of point of fixity 1a, pulling force sensor 2a, wire rope 3a, lever 4a, pulling force sensor 2a is connected with lever 4a with point of fixity 1a respectively by wire rope 3a, and point of fixity 1a, pulling force sensor 2a, wire rope 3a all are arranged on the two ends of lever 4a, and about the lever 4a layout that is centrosymmetric.The geometric center place of lever 4a has square hole 44a, and square hole 44a is for connecting the connecting hole of equipment under test.When with the moment of torsion of this measurement device rotary drilling rig, the drilling rod of rotary drilling rig is connected with measurement mechanism by square hole 44a, after starting rotary drilling rig, the moment of torsion that unit head rotation on it produces is delivered on the lever 4a through drilling rod, lever 4a rotates, and pulling force sensor 2a tension also shows the size of suffered pulling force.The moment of torsion that half of length that the pulling force sum that pulling force sensor 2a is subjected to multiply by lever produces when being this rotary drilling rig operation.
Obviously, when using above-mentioned torque-measuring apparatus, if the position that plant equipment is stopped is not accurate enough, perhaps plant equipment is swung, the position of lever 4a will be offset so, make that the arm of force of pulling force no longer is half of length of lever, measured torque value can produce bigger error thereupon, and this greatly reduces the measuring accuracy of measurement mechanism.And the pulling force gap that the pulling force arm of force of these measurement mechanism both sides does not wait the pulling force sensor 2a that will cause both sides to be subjected to is bigger, the phenomenon of pulling force sensor 2a overload may occur, causes problems such as pulling force sensor 2a damage easily.
