Description

Technical Field

[0001] This invention belongs to the technical field of variable diameter winches, specifically a vertical variable diameter cable winch control system. Background Technology

[0002] Traditional winches are generally horizontal structures. Vertical structures can easily cause the cables to become tangled and misaligned on the vertical drum due to their own weight. Moreover, the control systems of traditional winches are generally suitable for laying or winding cables of fixed diameter. When encountering cables of varying diameters, it is easy for smaller diameter cables to become embedded in larger diameter cables, or for larger diameter cables to become entangled with smaller diameter cables, resulting in cross-cutting and misalignment. This leads to defects such as uneven arrangement, cable stacking, and layering. These defects will affect the subsequent cable laying efficiency and normal cable winding and unwinding, and may also cause cable damage.

[0003] Therefore, the present invention specifically provides a vertical variable diameter cable winch control system to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a vertical variable diameter cable winch control system, which is suitable for operation under various working conditions. It can solve the problem of cable misalignment on the drum caused by changes in cable weight and cable diameter, realize automatic cable laying and winding operations, and has functions such as length measurement, speed measurement, automatic cable diameter detection, variable diameter adaptive cable winding and unwinding, automatic adjustment of traction conveying, automatic adjustment of traction tension, and dehumidification and heating. It features fully automated detection and control, convenient operation, and wide applicability.

[0005] To solve the above technical problems, the present invention provides a vertical variable diameter cable winch control system, including a control module, a detection feedback module, a variable diameter adjustment module and an alarm module. The control module is used to control the cable laying or winding action of the vertical variable diameter cable winch. The detection feedback module is used to collect information during the cable laying or winding process of the vertical variable diameter cable winch and feed it back to the control module and the variable diameter adjustment module to complete the cable laying or winding of the variable diameter cable.

[0006] The detection feedback module detects an abnormal signal and feeds it back to the control module. The control module stops the cable laying or winding operation of the vertical variable diameter cable winch. At the same time, the control module sends a signal to the alarm module, and the alarm module issues an alarm signal.

[0007] Specifically, the abnormal signals include overspeed, stall, overtemperature, contact with limit switch, inverter malfunction, etc.

[0008] Furthermore, the control module includes a cable laying control switch, a PLC controller, a servo controller, and a cable laying servo motor;

[0009] The detection feedback module includes a drum encoder for real-time measurement of the length of the winding and unwinding rope, the number of cable layers and the position on the cable storage drum, a cable arranger encoder for real-time measurement of the position of the cable on the cable arranger, a cable diameter detection module for real-time measurement of the cable diameter, and a tension detection module for real-time measurement of the cable tension.

[0010] The variable diameter adjustment module includes a large and small pressure wheel switching mechanism that matches the change in cable diameter, a variable traction conveying adjustment mechanism that adapts to the change in cable diameter, and a traction tension adjustment mechanism that automatically adjusts to adapt to different diameter cables.

[0011] When the cable laying control switch is activated, the PLC controller collects information from the real-time measurements of the cable length on the drum by the drum encoder and the real-time measurements of the current position of the cable laying screw by the cable laying encoder. The PLC controller sends instructions to the servo controller to control the cable laying servo motor to drive the drum to rotate and complete the cable laying or winding action. When the cable diameter detection module detects a change in the cable diameter, it feeds back to the PLC controller. The PLC controller then sends instructions to the large and small pressure wheel switching mechanism, the variable traction conveying adjustment mechanism, and the traction tension adjustment mechanism to adaptively adjust according to the change in cable diameter, thereby completing the cable diameter change during the cable laying or winding process of the vertical variable diameter cable winch.

[0012] Specifically, the cable laying servo motor is a variable frequency motor, which can select speed mode cable laying and constant tension mode cable laying according to the process requirements of cable laying. The vertical variable diameter cable winch can steplessly change speed between the lowest speed of 0HZ and the highest speed of 50HZ. At the same time, the traction torque of the vertical variable diameter cable winch can be adjusted according to process requirements.

[0013] When the cable diameter detection module detects a change in cable diameter, it sends a change signal to the PLC controller. The PLC controller automatically selects cable laying data appropriate to the cable diameter based on the position and diameter data of the cable change, and sends instructions to the large and small pressure wheel switching mechanism, the variable traction conveying adjustment mechanism, and the traction tension adjustment mechanism. The large and small pressure wheel switching mechanism selects appropriate friction pressure wheels according to different cable diameters and detects the position of the pressure wheels. The variable traction conveying adjustment mechanism automatically adjusts the traction tension appropriate to cables of different diameters to ensure smooth cable traction and conveying despite changes in cable diameter. The traction tension adjustment mechanism automatically adjusts the cable winding tension and cable laying control parameters based on the change in the number of cable layers on the drum and the change in cable diameter to ensure neat and smooth cable laying for cables of different diameters.

[0014] Furthermore, the control module also includes a cable laying position calibration switch, and the detection feedback module also includes a cable laying speed detection switch. After the cable laying speed detection switch detects that the current vertical variable diameter cable winch is in a leading or lagging state, it feeds back its signal to the control module. The control module controls the cable laying position calibration switch to turn on and adjust the current cable laying state.

[0015] Furthermore, the calibration method after the cable position calibration switch is turned on includes calculating the theoretical position of the cable arranger under the current cable position state of the drum through a numerical model, the drum encoder accurately measuring the length of the cable being wound and unwound on the drum in real time, the cable arranger encoder accurately measuring the current position of the cable arranger, and the CPU module of the PLC controller calculating and processing the position of the cable arranger under the speed loop control and the real-time measured position of the cable arranger and the length of the cable being wound and unwound on the drum, and adjusting the speed of the cable arranger to keep the position of the cable arranger synchronized with the position of the cable on the drum.

[0016] Furthermore, the detection feedback module also includes a motor temperature rise detection module for detecting the temperature of the cable laying servo motor. When the temperature exceeds the allowable temperature, the detected signal is fed back to the alarm module, and the PLC controller controls the cable laying control switch to shut down the cable laying or cable winding operation of the vertical variable diameter cable winch.

[0017] Furthermore, the detection feedback module also includes a limit protection switch, which includes a proximity switch and an extreme position travel switch for limiting the movement of the cable laying device.

[0018] Furthermore, the control module also includes a flushing valve switch, which is used to flush away seawater and debris from the cable array during the cable retrieval process. The flushing valve switch is electrically connected to a flushing solenoid valve, which can automatically open to flush the cable during cable retrieval.

[0019] Furthermore, the diameter detection module is a photoelectric sensor or an ultrasonic sensor, enabling real-time detection of the cable diameter.

[0020] Furthermore, the cable storage drum of the vertical variable diameter cable winch has a structure in which the small diameter groove and the large diameter groove are concentrically arranged. The small diameter groove is located inside the large diameter groove. The structural design of the cable storage drum facilitates the release or winding of the variable diameter cable and avoids phenomena such as the small diameter cable embedding into the large diameter cable and the large diameter cable wrapping around the small diameter cable, thus ensuring the safety, reliability and stability of the invention during use.

[0021] The beneficial effects of this invention are:

[0022] 1. The control system of this invention is suitable for operation under various working conditions, and can realize automatic cable laying and winding operations of variable diameter cables. It has functions such as length measurement, speed measurement, automatic cable diameter detection, adaptive cable winding and unwinding with variable diameter, automatic adjustment of traction conveying, automatic adjustment of traction tension, and dehumidification and heating. It also has a speed / torque control mode selection function. This invention is simple to operate, fully realizes automated detection and automated control functions, can be applied to unattended working conditions, and has a wide range of applications.

[0023] 2. The control system of this invention can realize cable laying or winding operations with varying cable diameters. It uses photoelectric sensors (or ultrasonic sensors) to detect the cable diameter in real time. The variable traction conveying adjustment mechanism can adaptively adjust the cable according to changes in diameter. Specifically, the large and small pressure roller switching mechanism selects the appropriate friction pressure roller according to different cable diameters and detects the position of the pressure roller, automatically adjusting the traction tension to suit different cable diameters. This ensures smooth traction and conveying despite changes in cable diameter, solving the problem of cable detachment caused by the inability to adaptively adjust traction and conveying due to changes in cable weight and diameter. The control system of this invention can improve the efficiency of cable laying or winding, meeting the application requirements of variable diameter cables.

[0024] 3. The control system of the present invention can realize automatic cable laying and winding, so that the cable is neatly arranged on the drum and avoids cable damage. It can solve the problem of cable misalignment on the drum caused by changes in cable weight and cable diameter. Specifically, through the design of the traction tension adjustment module of the present invention, the tension of cable winding and cable laying control parameters can be automatically adjusted according to the number of cable storage layers on the drum and the changes in cable diameter, so as to ensure that cables of different diameters are neatly and smoothly arranged.

[0025] Furthermore, through the design of the limit protection switch of this invention, when the traction cable moves upward and reciprocates with the drum to the upper proximity switch, the cable arranger automatically reverses direction and moves downward, ensuring that the cable can be neatly arranged on the drum.

[0026] 4. The control system of the present invention has automatic fault diagnosis and alarm functions. When abnormal signals or warning messages occur during the cable laying or winding process of the vertical variable diameter cable winch, such as overspeed, stall, contact with limit position travel switch, abnormal cable tension, abnormal motor temperature rise, frequency converter failure, etc., the current cable laying or winding operation can be stopped in time, and an alarm signal can be issued through the alarm module to notify the maintenance personnel for maintenance in a timely manner, thereby improving the reliability, safety and service life of the winch.

[0027] 5. The control system of the present invention can solve the problem of cable detachment or skipping during cable laying or winding. Specifically, after the cable laying speed detection switch detects that the current vertical variable diameter cable winch is in a leading or lagging state, it feeds back the signal to the cable laying position calibration switch. The theoretical position of the cable laying device under the current cable position state of the drum is calculated by numerical model. The drum encoder accurately measures the length of the rope being wound and unwound on the drum in real time, and the cable laying device encoder accurately measures the current position of the cable laying device. The CPU module of the PLC controller calculates and processes the position of the cable laying device under the speed loop control with the real-time measured position of the cable laying device and the length of the rope being wound and unwound on the drum, and adjusts the speed of the cable laying device to achieve the purpose of keeping the position of the cable laying device and the position of the cable on the drum synchronized.

[0028] 6. The control system of the present invention has a flushing function, which can automatically open the flushing solenoid valve to flush the cable during cable retrieval, reduce the corrosiveness of seawater to the cable and winch, improve the service life of the winch, and improve the cable retrieval effect by washing away the debris on the cable, thus avoiding defects such as uneven arrangement, cable stacking, and layering caused by debris on the cable.

[0029] 7. The cable storage drum of the vertical variable diameter cable winch of the present invention has a structure in which the small diameter groove and the large diameter groove are concentrically arranged. This design facilitates the release or winding of the variable diameter cable and avoids the phenomenon of small diameter cable embedding into large diameter cable and large diameter cable winding around small diameter cable, thus ensuring the safety, reliability and stability of the present invention during use.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] In one specific embodiment of the present invention, such as Figure 1As shown, a vertical variable diameter cable winch control system includes a control module, a detection feedback module, a variable diameter adjustment module, and an alarm module. The control module controls the cable laying or winding actions of the vertical variable diameter cable winch. The detection feedback module collects information during the cable laying or winding process of the vertical variable diameter cable winch and feeds it back to the control module and the variable diameter adjustment module to complete the cable laying or winding of the variable diameter cable. When the detection feedback module detects an abnormal signal during the cable laying or winding process of the vertical variable diameter cable winch and feeds it back to the control module, the control module stops the cable laying or winding action of the vertical variable diameter cable winch. At the same time, the control module sends a signal to the alarm module, and the alarm module issues an alarm signal.

[0034] The abnormal signals include overspeed, stall, overtemperature, contact with limit switch, abnormal cable tension, abnormal motor temperature rise, and inverter failure. Specifically, the detection feedback module includes a speed detection module for detecting the speed of the cable laying servo motor. When an abnormal speed is detected, it feeds back to the control module to stop the current cable laying or cable winding action.

[0035] Specifically, the control module includes a cable laying control switch, a PLC controller, a servo controller, and a cable laying servo motor;

[0036] The detection feedback module includes a drum encoder for real-time measurement of the length of the winding and unwinding rope, the number of cable layers and the position of the cable storage drum; a cable arranger encoder for real-time measurement of the position of the cable on the cable arranger; a cable diameter detection module for real-time measurement of the cable diameter; and a tension detection module for real-time measurement of the cable tension.

[0037] The variable diameter adjustment module includes a large and small rope pressing wheel switching mechanism that matches the change in cable diameter, a variable traction conveying adjustment mechanism that adapts to the change in cable diameter, and a traction tension adjustment mechanism that automatically adjusts to adapt to different cable diameters.

[0038] When the cable laying control switch is activated, the PLC controller collects information from the real-time measurements of the cable length on the drum by the drum encoder and the real-time measurements of the current position of the cable laying screw by the cable laying encoder. The PLC controller sends instructions to the servo controller to control the cable laying servo motor to drive the drum to rotate and complete the cable laying or winding action. When the cable diameter detection module detects a change in the cable diameter, it feeds back to the PLC controller. The PLC controller sends instructions to the large and small pressure wheel switching mechanism, the variable traction conveying adjustment mechanism, and the traction tension adjustment mechanism, which adaptively adjust according to the change in cable diameter to complete the cable diameter change during the laying or winding process of the vertical variable diameter cable winch.

[0039] Specifically, the cable laying servo motor is a variable frequency motor, which can select speed mode for cable laying and constant tension mode for cable laying according to the process requirements. The vertical variable diameter cable winch can steplessly change speed between the lowest speed of 0HZ and the highest speed of 50HZ. At the same time, the traction torque of the vertical variable diameter cable winch can be adjusted according to process requirements.

[0040] When the cable diameter detection module detects a change in cable diameter, it sends a change signal to the PLC controller. The PLC controller automatically selects cable laying data appropriate to the cable diameter based on the position and diameter data of the cable change, and sends instructions to the large and small pressure wheel switching mechanism, the variable traction conveying adjustment mechanism, and the traction tension adjustment mechanism. The large and small pressure wheel switching mechanism selects the appropriate friction pressure wheel according to different cable diameters and detects the position of the pressure wheel. The variable traction conveying adjustment mechanism automatically adjusts the traction tension appropriate to different cable diameters to ensure smooth cable traction and conveying. The traction tension adjustment mechanism automatically adjusts the cable winding tension and cable laying control parameters based on the change in the number of cable layers on the drum and the change in cable diameter to ensure neat and smooth cable laying of different diameters.

[0041] Specifically, the control module also includes a cable laying position calibration switch, and the detection feedback module also includes a cable laying speed detection switch. After the cable laying speed detection switch detects that the current vertical variable diameter cable winch is in a leading or lagging state, it feeds back its signal to the control module. The control module controls the cable laying position calibration switch to turn on and adjust the current cable laying state.

[0042] Specifically, the calibration method after the cable position calibration switch is turned on includes calculating the theoretical position of the cable arranger under the current cable position state of the drum through a numerical model, the drum encoder accurately measuring the length of the cable being wound and unwound on the drum in real time, the cable arranger encoder accurately measuring the current position of the cable arranger, and the CPU calculating and processing the cable arranger position under speed loop control, the real-time measured cable arranger position, and the cable length data being wound and unwound on the drum, and adjusting the cable arranger speed to keep the position of the cable arranger synchronized with the position of the cable on the drum.

[0043] Specifically, the detection feedback module also includes a motor temperature rise detection module for detecting the temperature of the cable laying servo motor. When the temperature exceeds the allowable temperature, the detected signal is fed back to the alarm module, and the PLC controller controls the cable laying control switch to shut down the cable laying or cable winding operation of the vertical variable diameter cable winch.

[0044] In this embodiment, the detection feedback module also includes a limit protection switch, which includes a proximity switch and a limit position travel switch for limiting the movement of the cable laying device. During the cable laying process, the traction cable of the variable traction conveying adjustment mechanism moves upward and reciprocally with the drum. When it moves to the upper proximity switch and is detected by it, the cable laying device starts to change direction, and the traction cable moves downward with the drum to perform the cable winding operation. Similarly, when it moves to the lower proximity switch, the cable laying device changes direction again, and the traction cable moves upward with the drum.

[0045] If the cable laying device moves up or down and touches the limit switch, the current cable laying or winding operation will stop immediately, and an alarm will be output through the alarm module.

[0046] In this embodiment, the control module also includes a flushing valve switch. The flushing valve switch is used to flush away seawater and debris on the cable array during the cable winding process. The flushing valve switch is electrically connected to a flushing solenoid valve, which can automatically open to flush the cable during cable winding.

[0047] In this embodiment, the diameter detection module is a photoelectric sensor or an ultrasonic sensor to realize real-time detection of the cable diameter.

[0048] In this embodiment, the cable storage drum of the vertical variable diameter cable winch has a structure in which the small diameter groove and the large diameter groove are concentrically arranged, with the small diameter groove located inside the large diameter groove. If the large diameter cable is being discharged, the large and small diameter pressing wheel switching mechanism adjusts the large diameter pressing wheel to match it for discharge. After the large diameter cable is discharged, the small diameter pressing wheel is switched to discharge the small diameter cable.

[0049] In addition, the control system of the present invention has a dehumidification and heating function. The control module also includes a dehumidification and heating switch, and the detection feedback module also includes a humidity sensor. When the humidity sensor detects that the current ambient temperature is low or the air is humid, it sends a signal to the control module. The control module controls the dehumidification and heating switch to be turned on, and the dehumidification motor heats up quickly to achieve the purpose of dehumidification.

[0050] In this embodiment, the control system of the present invention is equipped with a touch screen display. The touch screen display can display parameters such as inverter current, torque, speed, rope length, and rope speed, and can set alarm values. All modules can be operated through the touch screen display, which is convenient and allows for an intuitive view of the current operating status of each module.

[0052] (1) Ambient temperature: marine environment; (2) humid air at sea; (3) shocks and vibrations generated during normal ship operation; (4) salt spray, oil mist and mildew mist.

[0053] (5) Power supply: AC380V 50HZ; Control power supply: AC220V; (6) No conductive dust, not easy to explode.
