Tension Force Equalizer in a Rope System Using a Proximity Sensor

Popis výsledku v původním jazyce

Different values of tension forces in the load-bearing ropes of elevators, which push the rope into the grooves of the traction discs with different pressure, are the cause of uneven wear of the grooves of the traction discs under operating conditions. Current technical standards in the EU stipulate that the load suspended on load-bearing ropes be evenly distributed to all ropes used, using one of many construction designs for tension force equalizers in the rope system. The main subject and primary objective of this paper is to present the construction design, 3D model and produced device of one of four produced prototypes; which were constructed in the &quot;Research and Testing Laboratory&quot;, and allow the setting differing values of tension forces in the system of ropes of a traction elevator, to values of the same size. The paper presents a sequence of activities and a description of the operations, which, when using a tension force equalizer, result is the weight of the load (in the more loaded branch of the rope system of the elevator) in the final phase of the experiment being evenly distributed in all cross-sections of the load-bearing ropes. Laboratory measurements were performed on the produced device, which enable the detection of tension forces in ropes and the magnitude of these forces in the required time period to be graphically displayed on a PC. The prototype tension force equalizer can show the functionality and practical applicability of the procedure of balancing the levels of tension forces, which are of unequal strengths that start of laboratory measurement.
