Operation principle:The hoist wire rope tension sensor for the shock loading that can dissipate, original steel wire rope can not be changed
The physical dimension of bascule, it is changed without any part of elevator equilibratory suspension, it is possible to it is worked to eliminate elevator
Steel wire rope steel wire rope tension measurement data kick problem caused by the factors such as shake vibration 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 leads to
Middle plate 1 is crossed, sliding block 5 is acted 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
Slide rail in move up and down, when ignoring the acceleration of tension sensor 4, expansion link 3 acts on the upper cover plate 4- of tension sensor 4
5 power is equal to steel wire rope tension, and by the way that tension sensor 4 is located between expansion link 3 and sliding block 5, steel wire rope tension is changed
The upper cover plate 4-1 of tension sensor is acted on for pressure, the groove of upper lid 4-1 top surfaces is engaged with hydraulic cylinder extension bar 3, 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 spoke sensor 4-5 upper surface, arc-shaped base 4-6 curved end is engaged with sliding block 5, bears to prop up caused by sliding block 5
Counter-force P ', support reaction P ' act on the lower surface of spoke sensor by arc-shaped base 4-6, spoke sensor in normal pressure P and
Strain is produced in the presence of support reaction P ', is measured by the foil gauge A that is provided with inside spoke sensor in normal pressure P and support reaction
Strain is produced in the presence of P ', so as to survey steel wire rope tension, as shown in figure 5, because 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 passes
Sensor 4-4 and pressing plate 4-3 can along upper cover plate 4-1 slide rail axially do it is small move, elastic deformation can occur between steel ball
Slided with relative, between the elastic reaction and steel ball and steel ball, steel ball and border between steel ball and steel ball, steel ball and border
Rubbing action under, shock loading decays to all directions in space because of elastic deformation to dissipate because of enough frictions, in steel
On cord direction of pull, the shock loading that spoke sensor receives greatly reduces, so as to eliminate steel wire rope because vibration etc. because
Influence of the load impacting caused by element to steel wire rope tension detection, it is possible to achieve exactly in real time monitoring steel wire rope tension with
Elevated weight.
