Detailed description of the invention
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
As shown in Figure 1, the utility model comprises: intrinsic safety handle control box (1), top panel (2), universal link switch (3), input terminal row (4), Flameproof box (5), intrinsic safety electric source module (6), non-intrinsic safety electric source module (7), PLC master control system (8), control system (9), intrinsic safety show case (10), intrinsic safety show case front panel (11), intrinsic safety LCDs (12), operation push-button (13), forward button (14), reversing button (15), stop button (16), scram button (17) and loudspeaker (18).
The top panel (2) of intrinsic safety handle control box (1) is provided with universal link switch (3), intrinsic safety handle control box (1) interior bottom portion is provided with input terminal row (4), intrinsic safety handle control box (1) left side is provided with Flameproof box (5), and Flameproof box (5) inside is provided with intrinsic safety electric source module (6), non-intrinsic safety electric source module (7), PLC master control system (8) and control system (9); Flameproof box (5) top is provided with intrinsic safety show case (10), intrinsic safety show case front panel (11) is provided with intrinsic safety LCDs (12), operation push-button (13), forward button (14), reversing button (15), stop button (16), scram button (17) and loudspeaker (18).
Fig. 2 is utility model works principle schematic.As shown in Figure 2, this handle driving mode Flameproof and intrinsically safe endless rope winch electrical controller with PLC master control system for core, control system, universal link switch are connected with PLC master control system, PLC master control system exports and is connected with intrinsic safety LCDs, frequency converter is connected with PLC master control system corresponding signal end, and the tachogen output signal connecting motor is connected with PLC master control system.
Working process of the present utility model is: exchanged down-hole in AC127V plant-grid connection Flameproof box (5) and powered to PLC master control system (8), control system (9) by non-intrinsic safety electric source module (7), intrinsic safety electric source module (6) is powered, to complete respective function to universal link switch (3), intrinsic safety LCDs (12), operation push-button (13), forward button (14), reversing button (15), stop button (16), scram button (17) and loudspeaker (18) as power supply.
