Multirope Friction Hoist Tension Balancing Device Optimization Analysis

Mine personnel lifting device along the shaft to enhance the coal, ore, machinery and equipment materials. Coal is commonly known as the "four pieces of" one of the elevator shaft in the mine the role of transport is very large, commonly known as the mine's "throat." Group Pingmei can turn in a mine north of a ventilation shaft on the use of the KMD2.8×4 Friction Hoist (layout diagram shown in Figure 1). According to the provisions of mine safety regulations, every two years, regardless of the wire rope hoist how to use, you must replace it, the new replacement wire rope, used to constantly run after loading the elongated, stretched after the main and auxiliary wire rope will cage when the wellhead and down, respectively, can not reach the place, it is necessary to let the side loading cage in place, then on the other side of the cage to the tank, and then loading; so in order to later make the changes to enhance the efficiency of machine operation was very low, so elevator maintenance personnel must be replaced in the finished wire rope hoist rope to continue after the adjustment, until the rope will not stretch so far.The main methods of adjusting the traditional rope rope by way of cut-off, and hydraulic balancing device although the tension rope can be adjusted, but the tension of the existing hydraulic balancing device to adjust the distance is short, adjusting the scope of justice is very limited, so how can improve machine a certain tension improved balance system so that the whole transfer process becomes simple fast rope clean, but also ensures that the tension of each rope into a very practical balance to the subject.Considering the hydraulic balancing device works best, so the contents of the main research topics are:1, the tension on elevator balance device to optimize the design transformation, an increase of the hydraulic adjusting rope trip, in order to achieve only hydraulic adjusting rope rope can be adjusted to suppress the transfer hoist rope to meet the requirements to ensure the shortest possible time to complete the adjustment of the rope so as to save a lot of manpower and resources mining; 2, the optimum design of the hydraulic adjusting rope for safety performance finite element analysis, analysis under static loads and dynamic loads of stress analysis, theoretical analysis from the tension of balancing device is designed to meet the production site requirements.
