The system comprises a drum, a speed reducer connected with the drum, a motor driving the speed reducer, and a control device electrically connected with the motor, wherein, the control device comprises a PLC (Programmable Logic Controller) (1) provided with a touch display screen (9), a frequency converter (7) connected between the PLC and the motor (5), a motor encoder (6) arranged on the motor (5) and electrically connected with the frequency converter, and a drum encoder (2) arranged on the drum (3) and electrically connected with the PLC (1). The utility model has the advantages of fast regulation, accurate positioning, good security and reliability, has the functions of digitally displaying depth and speed, displaying analog speed and analog depth, and displaying given speed and practical speed curve, and is classified as an ideal speed-regulation system for the mine hoist.
Description
Technical field: the utility model relates to a kind of speed governing system, relates in particular to a kind of mine hoist numerical control frequency conversion speed-adjusting system.
Background technology: at present, the control system of mine hoist adopts the mode of series resistance to carry out speed governing mostly, and main existence startup and parking are impacted big, and speed governing is unsmooth, the energy consumption height; Though occurred variable-frequency control technique in recent years, substantially all belong to open loop control, control accuracy is lower, and equipment operation is steady inadequately, and safe reliability is relatively poor.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide the mine hoist numerical control frequency conversion speed-adjusting system that a kind of speed governing is steady, impact shock is little, safe reliability is high.
To achieve these goals, the utility model is by the following technical solutions: it comprises cylinder, with this cylinder bonded assembly retarder, drive the motor of this retarder, the control setup that is electrically connected with this motor; Described control setup by the PLC that is provided with touch display screen, be connected frequency converter between this PLC and the motor, be arranged on the motor encoder that is electrically connected with this frequency converter on the motor, be arranged on the cylinder coder that is electrically connected with PLC on the cylinder and constitute.
Up-computer is electrically connected with PLC.
Compared with the prior art, therefore the utility model has realized full cut-off ring controls such as speed, electric current, position owing to adopted technique scheme, has overcome startup, has stopped and impact big defective; Have and regulate rapidly accurately, quicken, slow down steadily, accurate positioning, advantage such as safe reliability is good; In addition, owing to adopted touch-screen and up-computer, therefore can also realize remote monitor and control, but also have the degree of depth and speed numeric display, analog rate and analog depth demonstration, given speed curve and the demonstration of actual speed curve, fault generation and remove functions such as demonstration, sending dotter signal demonstration.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: PLC1 cylinder coder 2 cylinders 3 retarders 4 motors 5 motor encoders 6 frequency converters 7 up-computers 8 touch display screens 9
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: motor 5 drives cylinder 3 by retarder 4 and rotates, and motor 5 is controlled by frequency converter 7 by PLC1; PLC1 is electrically connected with cylinder coder 2 on being located at cylinder 3, and frequency converter 7 is electrically connected with motor encoder 6 on being located at motor 5, and touch display screen 9 is electrically connected with PLC1.For the ease of remote monitor and control, up-computer 8 is electrically connected with PLC1.
