Design and analysis of technical characteristics of a quick-release device for connecting the ropes ends for mobile ropeways

The quick-release devices of the ends of the carrying and traction ropes, which have the load capacity required by the tension condition of the rope system and a gentle mechanical effect on the structural elements of steel ropes, make it possible to ensure the rapid deployment and dismantling of mobile ropeways in the conditions of elimination of natural or man-made emergencies. The article discusses the design of the original device that provides a reliable and quick-release connection of the ends of the ropes, and also developed a mathematical model for predicting the load capacity of the specified device. The results of the analysis of the influence of the main design parameters of the connected ropes and fasteners of the device under consideration, as well as the mechanical deformation characteristics of steel ropes on the load capacity of the quick-release device are presented. The calculated dependences for the design of a quick-release device are proposed, taking into account the loading of the rope system during the operation of a mobile ropeway, as well as a methodology for selecting the existing standard size of the connecting device for the specified operating conditions.
