Description
Technical Field
The invention relates to the technical field of power transmission line construction machinery, in particular to a control system and a control method of an electric rope reel winding and unwinding device.
Background
In each process of power transmission line construction, a large number of ropes, including various types of wire ropes and di-yard ropes, are often required to be wound and unwound, and the ropes are generally housed in standardized special rope reels for transportation and use. When the rope winding and unwinding operation is carried out by matching with traction equipment such as a traction machine or a winch, the winding and unwinding device must ensure that the rope between the rope disc and the winding drum of the traction equipment maintains a certain tension, and the rope and the winding drum can maintain a relatively static state, so that the winding and unwinding operation is carried out safely. When the device is independently used for stretching and releasing the ropes, the ropes which are stretched and released on the rope reel are required to be adjusted to keep corresponding tension according to the requirement of the overhead height, so that the stretching and releasing operation is safely carried out, meanwhile, the rope reel is often required to be manually controlled to store or send out the ropes in the preparation stage of construction which is required to carry out the operation, and at the moment, the winding and releasing speed is required to be conveniently adjusted.
Based on the above construction requirement analysis, from the viewpoint of energy conversion, when the rope winding and unwinding operation is performed, the winding and unwinding device needs to consume the power equipped by itself to convert into mechanical energy to drive the rope to rotate, when the rope unwinding operation is performed, the winding and unwinding device needs to control the rope to provide proper resistance, at this time, the rope is passively rotated under the driving force of the rope, and the process of consuming mechanical energy is actually performed, so that the possibility of energy recovery and storage exists.
In the above-described construction scenario, from the current situation, or when there is no dedicated rope reel winding and unwinding device, a manual pulling manner is often adopted, so that not only are more operators occupied, but also the continuous and stable pulling force cannot be ensured, and safety accidents such as running and the like are often caused by human negligence. Or when the rope reel winding and unwinding device adopts a mechanical or hydraulic transmission mode, an internal combustion engine is generally adopted as power, fossil energy is required to be consumed during rope winding and unwinding operation, energy cannot be recovered during unwinding and unwinding operation, only the energy can be dissipated through heating of a mechanical device/transmission medium, and the energy utilization efficiency is low. Or because the rope reel winding and unwinding functions are single, the requirement of full operation scene mechanization cannot be covered, and meanwhile, the working parameters cannot be accurately measured and displayed in real time, and the safety risk can be caused by overload or human error.

6. The control method according to claim 5, wherein switching between the automatic mode and the manual mode is performed in accordance with a setting of a display controller, and the brake is operated in conjunction with switching of the operation switch.
7. The control method according to claim 5, wherein in the automatic mode, the actual tension Fn of the rope is automatically adjusted by dynamic calculation according to the display controller setting tension F according to the following formula:
f n =f×k when the motor is in the motor state;
when the motor is in a generator state, F n =f/K;
wherein:
e is the current SOC value of the power battery, E is more than or equal to 0 and less than or equal to 1;
K max is the upper limit constant value of the adjustment coefficient, K max >1, which can be preset according to design and debugging;
K min is the upper limit constant value of the adjustment coefficient, K min <1, which can be preset according to design and debugging;
E max is a high power constant value of the power battery SOC, E min is a low power constant value of the power battery SOC, wherein 0<E min＜Emax is less than 1, and the power battery SOC can be preset according to design and debugging.
8. The control method according to claim 5, wherein in the automatic mode, if the display controller monitors that the SOC of the power battery is not less than 95%, the display controller transmits a signal to the motor controller, and the motor controller controls the brake resistor to operate according to the received signal until the SOC of the power battery is not more than 90%, and if the display controller monitors that the motor is in an abnormal state of the generator, the display controller transmits a signal to the motor controller, and the motor controller controls the brake resistor to operate according to the received signal until the voltage and current values are lower than the calibration values and the proper time is maintained.
9. The control method according to claim 5, wherein in the automatic mode, if the display controller monitors that the power battery voltage reaches a preset voltage, the display controller sends a signal to the motor controller, the motor controller controls the brake resistor to operate according to the received signal until the power battery voltage reaches a rated value, and if the display controller monitors that the motor is in an abnormal state of the generator, the display controller sends a signal to the motor controller, and the motor controller controls the brake resistor to operate according to the received signal until the voltage and the current value are lower than the rated values and the proper time is maintained.
