Lifting control device with skip emptying function

Abstract

The invention belongs to mine lifting control technologies and provides a lifting control device with a skip emptying function. The lifting control device with the skip emptying function comprises an operating control system for automatically controlling a running process of a lifting system, a speed-adjusting system and a monitoring system, wherein the speed-adjusting system is used for supplying electricity to a motor and adjusting and controlling a running speed of an elevator, and the monitoring system is used for operating and monitoring a running process of the lifting control device. A fixed interval is arranged in a hardware mode or a combination mode of hardware and software; the elevator is in a full brake release state, and when a skip enters the set interval at a constant speed, sampling reading is continuously performed to current of a speed regulator in a circulating mode, and whether the skip is emptied is judged; and if the skip is not emptied, adopted corresponding measures are continuously taken to unload the skip which is not emptied. The lifting control device with the skip emptying function improves safe production capability of the lifting system, eliminates lifting intermittent time during the loading process of the skip, and improves production efficiency.

Description

technical field [0001] The invention belongs to mine hoisting control technology, and mainly proposes a hoisting control device with the function of ensuring skip emptying, which is suitable for controlling the entire hoisting system including a main shaft hoist and a loading and unloading station. Background technique [0002] At present, the known hoist control device only controls the hoist itself, and has not realized an integrated design with the mining signal system or loading and unloading system. The incoming simple message requesting a lift acts as a start signal for the hoist. Take the main shaft hoist for skip lifting as an example. The skip is loaded by the fixed-weight measuring bucket of the loading system at the bottom of the well. The gate of the weighing bucket is opened, and the mineral material is loaded into the skip. After loading, the gate of the weighing hopper is closed. The skip is unloaded at the wellhead by a fixed unloading curved track or a hy...

AI Technical Summary

Problems solved by technology

The skip is unloaded at the wellhead by a fixed unloading curved track or a hydraulic (pneumatic) mechanism to open the skip unloading port; the main well hoist for skip lifting mainly has the following disadvantages: 1) The skip may not be completely unloaded, and the skip may not be completely unloaded. Fixed weight loading without unloading, resulting in overload operation of the hoist

Once the hoist is seriously overloaded, it will cause severe heating of the motor, fatigue damage to the hoisting wire rope and the hoist at the slightest level; at the worst, the overloaded skip will slip backwards, resulting in serious over-winding accidents that stop production and cause large economic losses. ;2) When the skip reaches the parking position and the hoist stops, the loading system starts loading operation, and the intermission time of hoisting is lengthened, which affects the hoisting efficiency and even affects the output of the mine; 3) The hoist control system is exchanged with the loading and unloading system The amount of information is limited, which affects the automation capability of the entire lifting system and the accurate statistics of lifting output
