Description

Technical Field

[0001] The invention relates to the technical field of power transmission line construction machinery, and in particular to a control system and a control method for an electric rope drum reeling device. Background Art

[0002] In each process of power transmission line construction, a large number of ropes need to be retracted and released. The ropes involved here include various types of steel wire ropes, Dilima ropes, etc. For transportation and use considerations, the ropes are generally stored in standardized special rope drums. When the rope is retracted and released in conjunction with traction equipment such as a traction machine or a capstan, the retracting and releasing device must ensure that the rope between the rope drum and the drum of the traction equipment maintains a certain tension, so as to ensure that the rope and the drum remain relatively static and the retracting and releasing operation can be carried out safely. When used independently for rope tension release, it is necessary to adjust the rope on the rope drum to maintain the corresponding tension according to the requirements of the overhead height, so as to carry out the release operation safely; at the same time, in order to carry out the construction preparation stage required for the above work, it is often necessary to manually control the rope drum to store or send out the rope, and at this time it is necessary to adjust the retracting and releasing speed more conveniently.

[0003] Based on the analysis of the above construction requirements, with regard to the control of the rope drum, from the perspective of energy conversion, when performing rope reeling operations, the reeling device needs to consume its own power and convert it into mechanical energy to drive the rope drum to rotate. When performing deployment operations, the reeling device needs to control the rope drum to provide appropriate resistance. At this time, the rope drum passively rotates under the driving force of the rope, which is actually a process of consuming mechanical energy. Therefore, there is the possibility of energy recovery and storage.

[0004] In the construction scenarios described above, from the current situation, when there is no dedicated rope drum reeling device, manual pulling is often used, which not only occupies a large number of workers, but also cannot guarantee the continuity and stability of the pulling force, and often causes safety accidents such as running off the line due to human negligence. When the rope drum reeling device adopts mechanical or hydraulic transmission methods, it generally uses an internal combustion engine as the power, which consumes fossil energy during the rope reeling operation, and cannot recover energy during the deployment operation. It can only dissipate energy through the heat of the mechanical device / transmission medium, and the energy utilization efficiency is low. Because the rope drum reeling function is relatively single, it cannot cover the mechanization needs of the entire operation scene, and it cannot accurately measure the working parameters and display them in real time, which may lead to safety risks due to overload or human error.

[0015] Automatic mode;

[0016] Set the working switch to automatic, and the rope drum bracket assembly is in the working state of automatic mode;

[0017] In automatic mode, the control system of the electric rope drum take-up and release device enters an adaptive working state. At this time, the motor works in torque mode, and the rope between the drum of the traction equipment and the rope drum of the rope drum support assembly is always kept in a tensioned state, and the tension corresponds to the torque of the motor; the torque of the drive unit is set and changed through the display controller; when the traction equipment is towing, the display controller sends a control signal to the motor controller according to the power provided by the power battery, and the motor controller controls the motor to drive the drum shaft to rotate according to the received control signal to control the drum shaft to take up the line, so as to realize the conversion of the power provided by the power battery into mechanical energy; the rope keeps the tension stored on the rope drum of the rope drum support assembly; when the traction equipment reverses the wire feeding, the drum shaft pays off the wire and drives the motor to rotate and returns the mechanical energy obtained by the rotation to the power battery through the motor controller, so as to realize the conversion of the mechanical energy of the drum shaft rotation into electrical energy; when the traction equipment stops, the rope of the rope drum support assembly keeps the tension on standby;

[0018] Manual Mode:

[0019] Set the working switch to manual mode, and the rope drum bracket assembly is in the working state of manual mode;

[0020] When the working switch is in the stop position, the display controller controls the motor controller to stop outputting current, and the brake is in a braking state. At this time, the rope drum of the rope drum bracket assembly is in a stationary state; when the working switch is in the wire-reeling position, the display controller controls the motor controller to control the motor to rotate forward at a set speed, and controls the brake to be in a released braking state, driving the rope drum of the rope drum bracket assembly to reel in, and the rotation speed can be adjusted steplessly and continuously through the display controller; when the working switch is in the wire-feeding position, the display controller controls the motor controller to control the motor to rotate reversely at a set speed, and the display controller controls the brake to be in a released braking state, driving the rope drum of the rope drum bracket assembly to release, and the rotation speed can be adjusted steplessly and continuously through the display controller.

[0021] In one embodiment of the present invention, the switching between the automatic mode and the manual mode is based on the setting of the display controller, and the operation of the brake is linked to the switching of the operation switch.

[0022] In one embodiment of the present invention, in the automatic mode, the actual tension Fn of the rope is automatically dynamically calculated and adjusted according to the tension F set by the display controller according to the following formula:

[0023]

[0024] When the motor is in the motor state, Fx = F × K;

[0025] When the motor is in generator mode, F n =F / K;

[0026] Where:

[0027] E is the current SOC value of the power battery, 0≤E≤1;

[0028] K max K is the upper limit constant value of the adjustment coefficient, max >1, can be set in advance according to design and debugging;

[0031] In one embodiment of the present invention, the switching of the brake resistor operation is triggered by the power battery SOC. In the automatic mode, if the display controller detects that the power battery SOC is ≥ 95%, the display controller sends a signal to the motor controller, and the motor controller controls the brake resistor to work according to the received signal until the power battery SOC is ≤ 90%; if the display controller detects that the motor is in an abnormal generator state, the display controller sends a signal to the motor controller, and the motor controller controls the brake resistor to work according to the received signal until the voltage and current values ​​are lower than the calibrated values ​​and maintained for an appropriate time.

[0032] In one embodiment of the present invention, the switching of the brake resistor operation is triggered by the voltage of the power battery. In the automatic mode, if the display controller detects that the power battery voltage reaches the preset voltage, 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 power battery voltage reaches the rated value; if the display controller detects that the motor is in an abnormal generator state, 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 current values ​​are lower than the calibrated values ​​and maintained for an appropriate time.

[0033] The above technical solution of the present invention has the following advantages compared with the prior art:

[0034] The control system of the electric rope reel reeling and releasing device described in the present invention has two modes, automatic and manual, and can be adapted to the coordinated operation of the capstan, and can also be used as a separate device to reel in ropes and cables.

[0035] The operating parameters of the control system of the electric rope reel taking-up and unwinding device of the present invention can be displayed in real time, faults can be automatically monitored and alarmed, and the source of the faults can be automatically determined and displayed.

[0036] The control system of the electric rope reel taking-up and releasing device described in the present invention is a fully electric drive based on PLC control. Compared with the rope taking-up device driven by an internal combustion engine and hydraulic transmission, it does not consume fossil energy, is energy-saving and environmentally friendly, and the output torque and power are not affected by high altitude and low temperature.

[0037] In the automatic mode of the control system of the electric rope reel taking-up and releasing device described in the present invention, there is no need to automatically match the operating speed with the capstan. The wire taking-up and wire feeding tensions are automatically adjusted in real time according to the battery power, ensuring that the rope tension meets the construction requirements while the tension is floatingly adjusted.

[0038] When the battery power in the control system of the electric rope reel taking-up and releasing device described in the present invention is low, the power consumption is reduced, the power generation is increased, and the use time of the equipment is effectively extended; when the battery power is high, the power consumption is increased and the power generation is reduced, effectively reducing the heat generated by the braking resistor.

[0046] Among them, in automatic mode, when the rope drum is in a winding state, the display controller sends a control signal to the motor controller according to the parameter information of the power battery collected by it (such as the SOC parameter of the power battery or the voltage parameter of the power battery), and the motor controller is supplied with electric energy by the power battery according to the received control signal, and controls the drive unit to drive the wire drum shaft to rotate, so as to control the wire drum shaft to wind up, so as to realize the conversion of electric energy provided by the power battery into mechanical energy; in automatic mode, when the rope drum is in a tension pay-out state, the wire drum shaft pay-out drives the drive unit to rotate and recharges the mechanical energy obtained by the rotation to the power battery through the motor controller, so as to realize the conversion of the mechanical energy of the rotation of the wire drum shaft into electric energy and store it in the power battery; in manual mode, the power battery supplies electric energy, and controls the drive unit to drive the wire drum shaft to rotate forward or reverse, so as to control the wire drum shaft to wind up or let out, and the speed of winding up or letting out is configured and adjusted through the display controller, so as to realize the conversion of electric energy provided by the power battery into mechanical energy.

[0047] This embodiment provides a control system for an electric rope reel take-up and release device, which can assist motorized capstans and other traction equipment to complete rope take-up and release operations, thereby improving the mechanization level and safety and reliability of rope take-up and release operations; it can also be used independently as a rope deployment device to provide stable and adjustable deployment tension for deployment operations. The electric rope reel take-up and release device adopts a modular split design, which effectively reduces the weight and volume of a single piece of equipment while ensuring equipment performance, thereby meeting the construction conditions of complex terrain in the field. Through automatic control of motor and battery output, intelligent adjustment of power generation and power consumption is achieved, extending the battery life of the equipment

[0049] In this embodiment, the control cabinet also includes a braking resistor, a temperature sensor and a cooling fan; the braking resistor is connected to the motor controller; the temperature sensor is connected to the braking resistor and is connected to the display controller for real-time measurement of the temperature of the braking resistor; the cooling fan is connected to the display controller; when the temperature of the braking resistor exceeds the calibrated upper limit, the display controller controls the cooling fan to dissipate heat for the braking resistor; when the temperature of the braking resistor is lower than the calibrated lower limit, the display controller controls the cooling fan to stop working. The calculation formula of the braking force is as follows: F z =F min ×K z , where: F z is the braking force, F minis the minimum braking force, K z It is the braking force conversion coefficient. It should be noted that the brake is calibrated according to its own hardware performance and construction requirements before leaving the factory.

[0050] In this embodiment, the control cabinet also includes an audible and visual alarm. The audible and visual alarm is connected to the display controller to provide a combination of indicator lights and sounds of different colors to display different operating states of the control cabinet. Specifically, when the motor is in a stopped state, the green light is on; when the motor is in a working state, the yellow light is on and flashes; when the motor control system fails, the red light is on and flashes, and the buzzer emits a sufficiently recognizable scream.

[0051] In this embodiment, the rope drum support assembly and the control cabinet are connected via a control cable.

[0052] In this embodiment, the motor controller and the display controller are connected via bus signals. The display controller and the power battery are connected via bus signals. It should be noted that the display controller includes a display and a controller.

[0053] The working principle of this embodiment is as follows:

[0054] Automatic mode;

[0055] Put the mode switch in the automatic mode, and the rope drum bracket assembly is in the automatic working state;

[0056] In automatic mode, the control system of the electric rope reel take-up and release device enters an adaptive working state. At this time, the motor works in torque mode, and the rope between the drum of the traction equipment and the rope reel of the rope reel bracket assembly is always kept in a tensioned state, and the tension corresponds to the torque of the motor; the torque of the drive unit is set and changed through the display controller; when the traction equipment is towing, the display controller sends a control signal to the motor controller according to the electric energy provided by the power battery, and the motor controller controls the motor to drive the reel shaft to rotate according to the received control signal to control the reel shaft to take up the wire, so as to realize the conversion of the electric energy provided by the power battery into mechanical energy; the rope keeps the tension stored on the rope reel of the rope reel bracket assembly; when the traction equipment reverses the wire feeding, the reel shaft pays off the wire and drives the motor to rotate and returns the mechanical energy obtained by the rotation to the power battery through the motor controller, so as to realize the conversion of the mechanical energy of the reel shaft rotation into electrical energy; when the traction equipment stops, the rope of the rope reel bracket assembly keeps the tension on standby.

[0057] The actual rope tension Fn is automatically adjusted dynamically based on the tension F set by the display controller according to the following formula:

[0058]

[0059] When the motor is in the motor state, F n =F×K;

[0060] When the motor is in generator mode, F n =F / K;

[0061] Where:

[0062] E is the current SOC value of the power battery, 0≤E≤1;

[0063] K max K is the upper limit constant value of the adjustment coefficient, max >1, can be set in advance according to design and debugging;

[0064] K min K is the upper limit constant value of the adjustment coefficient, min <1, can be set in advance according to design and debugging;

[0065] E max E is the high-capacity constant value of the power battery SOC; min is the low power constant value of the power battery SOC, where 0<E min <E max <1, can be set in advance according to design and debugging.

[0066] When the power battery is at low power, the motor control is biased towards the power generation condition. When the pulling force requirement is met, the power of the power generation condition is automatically increased and the power of the power consumption condition is reduced, effectively extending the endurance of the control cabinet.

[0067] When the power battery is at a high level, the control cabinet controls the power consumption condition, automatically reduces the power of the power generation condition, and increases the power of the power consumption condition, effectively reducing the working time of the braking resistor and reducing the heat generated thereby.

[0068] The switching of the brake resistor is triggered by the power battery SOC. In the automatic mode, when in the wire feeding position, if the display controller detects that the power battery SOC is ≥ 95%, the display controller sends a signal to the motor controller, and the motor controller controls the brake resistor to work according to the received signal until the power battery SOC is ≤ 90%; if the display controller detects that the motor is in an abnormal generator state, the display controller sends a signal to the motor controller, and the motor controller controls the brake resistor to work according to the received signal until the voltage and current values ​​are lower than the calibrated values ​​and maintained for an appropriate time.

[0069] Alternatively, the switching of the braking resistor is triggered by the voltage of the power battery. In the automatic mode, when in the wire feeding position, if the display controller detects that the power battery voltage reaches the preset voltage (the preset voltage is the fully charged power battery voltage), the display controller sends a signal to the motor controller, and the motor controller controls the braking resistor to work according to the received signal until the power battery voltage reaches the rated value; if the display controller detects that the motor is in an abnormal generator state, the display controller sends a signal to the motor controller, and the motor controller controls the braking resistor to work according to the received signal until the voltage and current values ​​are lower than the calibrated values ​​and maintained for an appropriate time.

[0070] Manual Mode:

[0071] Put the mode switch in the manual mode, and the rope drum bracket assembly is in the working state of the manual mode;

[0072] When the direction switch is in the stop position, the display controller controls the brake to be in a braking state, and the rope drum of the rope drum bracket assembly is in a stationary state; when the direction switch is in the reeling position, the display controller controls the brake to be in a released state, and the motor rotates forward to drive the rope drum of the rope drum bracket assembly to reel in, and the rotation speed can be adjusted steplessly and continuously through the display controller; when the direction switch is in the wire feeding position, the display controller controls the brake to be in a released state, and the motor rotates reversely to drive the rope drum of the rope drum bracket assembly to pay out, and the rotation speed can be adjusted steplessly and continuously through the display controller.

[0073] The switching between the automatic mode and the manual mode is based on the setting of the display controller, and the brake operation is linked to the switching of the mode switch and the direction switch. Specifically, when the mode switch is switched from the automatic mode to the manual mode, the display controller first controls the brake to brake, and then controls the motor to stop working. When the mode switch is switched from the manual mode to the automatic mode, the display controller first controls the motor to start working, and then controls the brake to open, which can ensure that the opening of the brake will not cause the rope to relax due to the decrease in tension.

[0074] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
