Abstract

The invention discloses a control method for an endless rope winch. An input device, an output end signal control device, a liquid crystal display and a voice playing device are respectively connected with a PLC (Programmable Logic Controller) to form an endless rope winch monitoring device; the PLC is used as the control core of an endless rope winch system; the control method of the endless rope winch system comprises a winch running control method, a secondary picture switching control method, a secondary urgency stop control method, a secondary voice control method, a secondary parameter control method, a secondary zero calibration control method and a secondary HSC0 control method. The control method can be used for controlling the endless rope winch and monitoring the running state of the winch in real time, has functions such as real-time display of winch position and speed, voice broadcast and fault record and can be used for comprehensively protecting the conditions such as overspeed, underspeed, set distance excess, sudden stop locking, machine head overwinding, machine tail overwinding and sudden stop during leakage in the running process of the endless rope winch.

Description

technical field [0001] The invention relates to a control method of an endless rope winch, in particular to a programmable controller (PLC) control method of the endless rope winch. Background technique [0002] Coal mine fully mechanized mining face is generally transported by small winches and battery cars, which requires a lot of manpower and material resources, with low safety factor, high accident rate, low transportation efficiency and high operating costs. The endless rope winch is a new type of coal mine auxiliary transportation equipment that has appeared in recent years and has been rapidly promoted. At present, the endless rope winch has been widely used in coal mines at home and abroad. Related utility model patents include: a mining endless rope transport console, authorized announcement CN 203065084 U, which involves the mechanical structure of the endless rope transport console; mine endless rope winch integrated electronic control device, authorized announcem...
