Method for load monitoring of steel wire rope of mine vertical shaft hoisting system

Abstract

The invention discloses a method for load monitoring of a steel wire rope of a mine vertical shaft hoisting system. According to the method, through the weight change value and the strain change valuecorresponding to the weight of the steel wire rope at a constant-speed lowering stage of a hoisting container, the strain change value corresponding to the unit weight of the steel wire rope is obtained; and the strain change value on a bearing block and the calibrated value of the weight of the steel wire rope measured in the empty loading lowering process are compared and calculated through anindustrial personal computer, so that the load variation value of the hoisting container in the loading-hoisting-unloading process is obtained, and is compared with a preset nuclear load, and therefore whether the tension of the steel wire rope of the hoisting system is abnormal or not is identified. The method has the advantages of being is simple in structure, convenient to use and replace and low in cost; measuring points are arranged on the bearing block, so that transformation and processing of the hoisting system are avoided, the influence of a monitoring system on the hosting system isreduced, the method is suitable for load monitoring of the various mine vertical shaft winding type hoisting systems and is good in measurement effect.

Description

technical field [0001] The invention relates to a method for monitoring the load of a steel wire rope in a mine shaft hoisting system, and is especially suitable for the load monitoring of a winding hoisting mine shaft system. Background technique [0002] The hoist is an important equipment widely used in industrial and mining enterprises. The hoisting wire rope is an important load-bearing component in the mine hoisting system. Therefore, it is necessary to properly maintain the hoisting wire rope, detect the tension of the hoisting wire rope in real time, and prevent the tension of the hoisting wire rope from exceeding its own tolerance. broken by the limit. [0003] At present, there is no practical monitoring method for the load of the hoist in the hoisting of mine shafts. Therefore, when the hoist is overloaded during operation, an alarm signal cannot be sent to remind the hoist driver to stop running immediately. Once such an accident occurs, it often causes serious d...

Problems solved by technology

[0003] At present, there is no practical monitoring method for the load of the hoist in the hoisting of mine shafts. Therefore, when the hoist is overloaded during operation, an alarm signal cannot be sent to remind the hoist driver to stop running immediately. Once such an accident occurs, it often causes serious damage. personal and property damage

The general monitoring method is to install a pressure sensor at the end of the wire rope, which easily destroys the original integrity of the wire rope, and also affects the normal production of the hoist during the transformation period, and is not convenient for maintenance and replacement of the monitoring device.
