Given method for on-line detection of additional starting moment loaded mine hoist

Abstract

The invention relates to a given method for on-line detection of an additional starting moment of a loaded mine hoist, which comprises the following steps that: firstly, a tension sensor measures the tension of a steel wire rope for detecting the load weight in real time, a sending device sends out modulated signals in a wireless mode, a receiving device converts the wireless signals into voltage signals to obtain digital weight signals and transmits the digital weight signals to a singlechip, then, the singlechip calculates the digital weight signals to obtain the additional starting moment signals to be overlapped, the additional starting moment signals are sent to a host machine through a serial bus, finally, the host machine integrates the starting moment signals and the additional starting moment signals, sets overlapping current signals corresponding to the overlapping moment and judges whether a mechanical switch is switched off or not, when the mechanical switch is switched off, the overlapping current signals are output to a controller motor, and the motor is ensured to be started. The given method for on-line detection of the additional starting moment of the loaded mine hoist can simultaneously meet the starting requirement of the hoist under the conditions of heavy load, light load or idle load, the reverse rotation phenomenon occurring when the hoist is started is avoided, and the mine production safety is improved.

Description

technical field [0001] The invention relates to a method for setting the additional starting torque of a mine hoist, in particular to a method for setting the additional starting torque of a mine hoist for online load detection. Background technique [0002] In mine production using vertical shaft hoisting, the operating status of the hoist is directly related to the safe production of the mine. At present, most vertical shaft hoists use double skips for lifting. When it is empty, it can be considered that the resistance moment of the hoist is approximately zero. When it is loaded, the resistance moment of the hoist is generated by the weight of the lifted goods. When the mechanical brake is released and the hoist starts, the weight of the hoisted cargo is immediately borne by the starting torque generated by the motor, that is, a step load is given to the motor. If the lifting starting torque provided by the motor is less than the resistance torque of the lifting system du...
