Face.
Working principle: the hoist wire rope tension sensor for the shock loading that can dissipate can not change original wirerope
The structure size of balancing device is changed without any part of elevator equilibratory suspension, so that it may it is worked to eliminate elevator
Wirerope is because of steel wire rope tension measurement data kick problem caused by shaking the factors such as trembling in journey.In use, steel wire
Rope, middle plate 1 and sliding block 5 are fixed together, and hydraulic cylinder 2, pressing plate 7 and side plate 6 are fixed together, and steel wire rope tension is logical
Middle plate 1 is crossed, sliding block 5 acts on the arc-shaped base 4-5 of tension sensor 4, and tension sensor 4 can be as sliding block 5 be in side plate 6
Sliding rail in move up and down, when ignoring the acceleration of tension sensor 4, telescopic rod 3 acts on 4 upper cover plate 4- of tension sensor
5 power is equal to steel wire rope tension and is changed steel wire rope tension by the way that tension sensor 4 to be located between telescopic rod 3 and sliding block 5
The upper cover plate 4-1 of tension sensor is acted on for pressure, the groove of the top surface upper cover 4-1 is matched with hydraulic cylinder extension bar 3, is born
Normal pressure P on hydraulic cylinder extension bar 3, normal pressure is by upper cover plate 4-1, and steel ball particle 4-2, pressing plate 4-3 are by positive pressure
In the upper surface of spoke sensor 4-5, the curved end of arc-shaped base 4-6 is matched with sliding block 5, bears the branch that sliding block 5 generates
Counter-force P ', support reaction P ' act on the lower end surface of spoke sensor by arc-shaped base 4-6, spoke sensor in normal pressure P and
Strain is generated under the action of support reaction P ', is measured by the foil gauge A that is equipped with inside spoke sensor in normal pressure P and support reaction
Strain is generated under the action of P ', so that steel wire rope tension is surveyed, as shown in figure 5, since steel wire rope tension by hydraulic cylinder 2 and stretches
The pressure that bar 3 is transformed into have passed through steel ball particle in transmittance process, and when steel wire rope tension has fluctuation and impact, spoke is passed
Sensor 4-4 and pressing plate 4-3 can along upper cover plate 4-1 sliding rail axially do it is small move, flexible deformation can occur between steel ball
With opposite sliding, between the elastic reaction and steel ball and steel ball, steel ball and boundary between steel ball and steel ball, steel ball and boundary
Rubbing action under, shock loading decays due to flexible deformation to all directions in space to dissipate because of enough frictions, in steel
On cord direction of pull, the shock loading that spoke sensor receives greatly reduces, thus eliminate wirerope because trembling etc. because
Influence of the load impacting caused by element to steel wire rope tension detection, exactly may be implemented real-time monitoring steel wire rope tension with
The weight being elevated.
