Abstract

The invention discloses a multi-loop comprehensive control device for a coal mine fully-mechanized excavation working surface. The multi-loop comprehensive control device comprises an anti-explosion shell, and is characterized in that: the anti-explosion shell comprises an isolation switch cavity and a main control cavity; a group of isolation switches are arranged in the isolation switch cavity;each isolation switch is connected with a group of driver units; all the driver units are arranged in the main control cavity; each driver unit is connected with a protection card unit; the protection card unit is connected with a protection card power supply unit; the protection card power supply unit is connected with a programmable logic controller (PLC); and the PLC is connected with a keyboard and a liquid crystal display screen. The multi-loop comprehensive control device can simultaneously and comprehensively control different sets of power supply voltage equipment of a fully-mechanized excavator, an adhesive tape conveyor and a winch, so that the shortcomings of complicated wire connection, difficulty in moving and the like of the conventional underground fully-mechanized excavation working surface control method are overcome.

Description

technical field [0001] The invention relates to the field of control of coal mine fully mechanized excavation face, in particular to a multi-circuit comprehensive control device for coal mine mechanized excavation face. Background technique [0002] The existing underground fully mechanized excavation face equipment is controlled by a single magnetic starter. After years of use, this control method has many shortcomings such as cumbersome wiring and difficult relocation. This situation greatly restricts my country's high-yield The popularization of high-efficiency comprehensive mechanized excavation face cannot meet the needs of high-efficiency and fast excavation. This is the weak point of prior art. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-circuit integrated control device for fully mechanized coal mine excavation face, which improves the technical level of coal mine electric control and has high...
