Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] The technical solutions provided by various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] Figure 1 This is a schematic diagram of the structure of a cable winding and unwinding device provided in an embodiment of this application, as shown below. Figure 1As shown, the cable winding and unwinding device may include: a roller assembly 1, a cable, a tensioner assembly 2, and an electrical control assembly 3. The roller assembly 1 is connected to the tensioner assembly 2 via the cable. The roller assembly 1 includes: a roller body 14, a first support assembly 11, and a first drive assembly 13. The roller body 14 and the first drive assembly 13 are both mounted on the first support assembly 11, and the first drive assembly 13 is electrically connected to the electrical control assembly 3. The tensioner assembly 2 includes: a tensioner body 23, a second support assembly 21, and a second drive assembly 22. The tensioner body 23 and the second drive assembly 22 are both mounted on the second support assembly 21, and the second drive assembly 22 is electrically connected to the electrical control assembly 3.

[0028] It is important to understand that Figure 1 The cable winding and unwinding device shown is merely an example where the drum body 14 is not yet mounted on the first support assembly 11, and is not intended to be limiting. Therefore, the specific structure of the cable and the drum body 14 is not described in detail. Figure 1 This is reflected in the text. Furthermore, the electronic control component 3 is electrically connected to the first drive component 13 and the second drive component 22 via wiring, and is not shown in the text. Figure 1 This is reflected in the text.

[0029] Tensioners are commonly used retaining devices in belt and chain drive systems. Their function is to maintain appropriate tension on the belt or chain during transmission, thereby preventing belt slippage, timing belt skipping or tooth breakage, and chain loosening or slippage, and reducing wear on sprockets and chains. Tensioners come in various structures, broadly categorized as fixed or self-adjusting. Fixed tensioners often use fixed adjustable sprockets to adjust belt and sprocket tension, while self-adjusting tensioners typically use elastic components that automatically rebound to control belt and chain tension. Self-adjusting chain tensioners can employ spring structures or rubber components.

[0030] It should be understood that the connection methods between the various components mentioned above can be selected according to actual needs, and no limitation is made here. For example, they can be fixed by welding or by bolts.

[0031] The cable winding and unwinding device provided in this application embodiment differs from the prior art where the tensioner uses a hydraulic drive method, which is not environmentally friendly. It can control the first drive component and the second drive component through an electronic control component, thereby driving the drum body and the tensioner body, avoiding the leakage of hydraulic oil and environmental pollution caused by the hydraulic drive method.

[0032] Figure 2 This is a schematic diagram of a cable winding and unwinding device provided in an embodiment of this application.

[0033] The structure of the first driving component 13 will be described in further detail below, such as... Figure 2 As shown, the first drive assembly 13 may include a first motor 131, which is electrically connected to the electronic control assembly 3; the roller assembly 1 may further include a first brake 15, which is electrically connected to the electronic control assembly 3. Thus, the electronic control assembly can control the first motor to drive the roller body, or it can control the first brake to brake the roller body, thereby controlling the rotational speed of the roller body.

[0034] The first motor 131 can be a variable frequency motor. Compared with ordinary motors, variable frequency motors are easier to speed adjust and more energy-efficient; in addition, variable frequency motors can increase capacity, achieve high speed and high voltage operation, and can achieve soft start and fast braking, etc.

[0035] like Figure 2 As shown, the cable reeling and releasing device provided in this embodiment of the application, in Figure 1 Based on the cable winding and unwinding device shown, the first support assembly 11 is further subdivided. For example, the first support assembly 11 may include: a first support 112 and a second support 113. One end of the roller body 14 can be connected to the first support 112, and the other end of the roller body 12 can be connected to the second support 113; the first drive assembly 13 can be disposed on the first support 112.

[0036] It should be understood that the specific location of the first drive component 13 can be selected according to actual needs and is not limited here. For example, the first drive component 13 can be located on the side of the first bracket 112 away from the second bracket 113, or it can be located on the side of the first bracket 112 closer to the second bracket 113.

[0037] Optionally, in one embodiment of this application, the first support 112 may include a support portion and a shaft portion, the shaft portion being connected to and extending relative to the support portion; the first drive assembly 13 may further include a first reducer 132 and a first clutch 133; the output shaft of the first motor 131 may be connected to the input shaft of the first reducer 132, the output shaft of the first reducer 132 may be connected to the input end of the first clutch 133, and the output end of the first clutch 133 may be connected to the shaft portion of the first support 112; wherein, the first motor 131, the first reducer 132, and the first clutch 133 may all be disposed on the support portion of the first support 112. Thus, the rotation of the roller body can be controlled by the mutual cooperation of the first motor, the first reducer, and the first clutch.

[0038] Optionally, in one embodiment of this application, the second bracket 113 may include a support portion and a shaft portion, the shaft portion being connected to the support portion and extending relative to the support portion; the first brake 15 may be disposed on the support portion of the second bracket 113 and connected to the shaft portion of the second bracket 113. Thus, by providing the first brake on the second bracket, the roller body can be braked, thereby controlling the rotational speed of the roller.

[0039] The first brake 15 can be a magnetic powder brake, also known as a magnetic powder actuator, which is based on electromagnetic principles and utilizes magnetic powder to transmit torque. Magnetic powder brakes have the characteristic that the excitation current and the transmitted torque are essentially linearly related. Independent of slip, magnetic powder brakes can transmit a certain torque and have advantages such as fast response speed, simple structure, no pollution, no noise, no impact vibration, and energy saving. Magnetic powder brakes are versatile and high-performance automatic control components, and are now widely used in unwinding and rewinding tension control in papermaking, printing, plastics, rubber, textiles, dyeing, wire and cable, metallurgy, tablet presses, and other related winding and processing industries. Magnetic powder brakes are also frequently used for dynamometer loading and braking in transmission machinery.

[0040] Understandable, Figure 2 The roller body 14, not shown, can be disposed between the shaft portion of the first support 112 and the shaft portion of the second support 113. That is, one end of the roller body 14 can be connected to the shaft portion of the first support 112, and the other end of the roller body 12 can be connected to the shaft portion of the second support 113.

[0041] Furthermore, the first support 112 can be a fixed support, and the second support 113 can be a movable support, thus the distance between the first support 112 and the second support 113 can be adjusted. Specifically, as shown... Figure 2 As shown, the cable reeling and releasing device provided in this embodiment of the application, in Figure 1 The cable reeling and unloading device shown has additional components, such as an adjustment assembly.

[0042] The adjustment component mentioned above is an optional component in the cable winding and unwinding device provided in this application embodiment. It should be understood that whether the cable winding and unwinding device provided in this application embodiment includes the adjustment component can be selected according to the actual application scenario, and is not limited here.

[0043] like Figure 2 As shown, the roller assembly 1 may further include an adjustment assembly 12, which may include at least one of an electric push rod 121, a limit switch 122, and a linear displacement sensor 123.

[0044] The linear displacement sensor 123, also called an electronic ruler, is essentially a sliding rheostat (including a variable resistance rail and a slider). The function of the linear displacement sensor is to convert linear mechanical displacement into an electrical signal. To achieve this, the variable resistance rail is typically placed at a fixed position on the sensor, and different resistance values ​​are measured by the displacement of the slider on the rail. The sensor rail is connected to a steady-state DC voltage, allowing a small current of microamperes to flow. The voltage between the slider and its starting point is proportional to the length the slider moves. Using the sensor as a voltage divider minimizes the requirement for accurate total resistance of the rail, because resistance changes caused by temperature variations do not affect the measurement results.

[0045] Optionally, in one embodiment of this application, such as Figure 2 As shown, when the adjustment assembly 12 may include an electric push rod 121, one end of the electric push rod 121 may be connected to the fixed bracket, and the other end of the electric push rod 121 may be connected to the movable bracket; the electric push rod 121 may be electrically connected to the electronic control assembly 3.

[0046] When the adjustment component 12 may include a limit switch 122, the limit switch 122 may be disposed on the movable bracket on the side close to the fixed bracket; the limit switch 122 may be electrically connected to the electronic control component.

[0047] When the adjustment assembly 12 may include a linear displacement sensor 123, the linear displacement sensor 123 may include a fixed end component and a movable end component. The fixed end component of the linear displacement sensor 123 may be fixedly connected to the fixed bracket, and the movable end component of the linear displacement sensor 123 may be fixedly connected to the movable bracket. The linear displacement sensor 123 may be electrically connected to the electronic control assembly 3.

[0048] It is important to understand that, although Figure 2 The adjustment assembly 12 shown may include an electric actuator 121, a limit switch 122, and a linear displacement sensor 123. The embodiments described above are illustrated in the order that the adjustment assembly 12 includes the electric actuator 121, the limit switch 122, and the linear displacement sensor 123. However, the above description is merely illustrative and not intended to be limiting. That is, for example, the adjustment assembly 12 may also include the electric actuator 121 and the limit switch 122, or it may also include the electric actuator 121 and the linear displacement sensor 123, etc.

[0049] Thus, the distance between the first and second supports can be adjusted by using at least one of an electric push rod, a limit switch, and a linear displacement sensor.

[0050] Optionally, such as Figure 2 As shown, the first support assembly 11 may further include: a base 111 and a linear module 114. The first support 112 may be disposed on one side of the base 111, and the second support 113 may be disposed on the other side of the base 111. The linear module 114 may be disposed on the end face of the base 111 away from the ground. One end of the linear module 114 may be connected to the first support 112, and the other end of the linear module 114 may be connected to the second support 113.

[0051] It is understood that the linear module 114 may include a slide rail and a slider; the slide rail may be mounted on the end face of the base 111 away from the ground, one end of the slide rail may be connected to the first bracket 112, and the other end of the slide rail may be connected to the second bracket 113; the slider may slide on the slide rail, and one end of the slider may be fixedly connected to the second bracket 113. Thus, the second bracket can be moved by the slider sliding on the slide rail.

[0052] Furthermore, such as Figure 2 As shown, the cable winding and unwinding device provided in this embodiment of the application can... Figure 1 Additional components, such as a tension detection assembly, have been added to the cable reeling and unloading device shown.

[0053] The tension detection component mentioned above is an optional component in the cable winding and unwinding device provided in this application embodiment. It should be understood that whether the cable winding and unwinding device provided in this application embodiment includes a tension detection component can be selected according to the actual application scenario, and is not limited here.

[0054] like Figure 2 As shown, the cable winding and unwinding device may further include a tension detection component 4, which may include a tension detection sensor 41. The tension detection sensor 41 may be in contact with the cable, and the tension detection sensor 41 may be disposed between the roller assembly 1 and the tensioner assembly 2, or the tension detection sensor 41 may be disposed outside the range between the roller assembly 1 and the tensioner assembly 2 and on the side close to the tensioner assembly 2.

[0055] Tension sensors are instruments used to measure the tension of rolled materials during tension control. Based on their operating principle, tension sensors can be divided into strain gauge type and micro-displacement type. Strain gauge type tension sensors connect a tension strain gauge and a compression strain gauge together in a bridge configuration. When subjected to external pressure, the resistance of the strain gauge changes proportionally to the magnitude of the tension. Micro-displacement type tension sensors apply an external load, causing a leaf spring to displace, and then detect the tension through a differential transformer. Because the displacement of the leaf spring is extremely small, it can be called a micro-displacement type tension detector. Furthermore, based on their external structure, they can be divided into: axial type, through-shaft type, cantilever type, etc. A strain gauge is an element used to measure strain, consisting of a sensitive grid. To ensure the strain gauge has a certain resistance value without being too long, the sensitive grid is made of 0.025mm diameter metal resistance wire. The sensitive grid is the core of the strain gauge; it is attached to an insulating substrate, with lead wires soldered to both ends, and a protective covering layer is attached to the top of the grid. The working principle of resistance strain gauges is based on the strain effect, that is, when a conductor or semiconductor material undergoes mechanical deformation under the action of external force, its resistance value changes accordingly. This phenomenon is called the "strain effect".

[0056] Specifically, when the cable winding and unwinding device is winding up the cable, the tension detection sensor 41 can be disposed between the roller assembly 1 and the tensioner assembly 2. At this time, the tension detection assembly 4 can also include a sensor base 42 and a pitch platform 43. The pitch platform 43 can be disposed between the roller assembly 1 and the tensioner assembly 2. The tension detection sensor 41 can be disposed on the sensor base 42, and the sensor base 42 can be movable along the extension direction of the pitch platform 43. The extension direction of the pitch platform 43 can be the same as the extension direction of the roller body 14.

[0057] The pitch platform 43 may include a bracket and a slide bar mounted on the bracket in the same direction of extension as the roller body 14. The sensor base 42 can slide on the slide bar, and the angle of the sensor base 42 on the slide bar can also be changed to adapt to the cables at various positions between the roller assembly 1 and the tensioner assembly 2, so that the cables come into contact with the tension detection sensor 41 and the tension of the cables can be detected in real time.

[0058] When the cable release device is releasing the cable, the tension detection sensor 41 can be located outside the range between the roller assembly 1 and the tensioner assembly 2 and on the side close to the tensioner assembly 2; at this time, the tension detection assembly 4 can also include a sensor base 42, and the tension detection sensor 41 can be disposed on the sensor base 42.

[0059] Thus, during the cable winding process, a tension sensor is installed between the roller assembly and the tensioner assembly to detect the cable tension in real time; during the cable unwinding process, a tension sensor is installed outside the range between the roller assembly and the tensioner assembly and on the side closer to the tensioner assembly to detect the cable tension in real time.

[0060] The structure of the second driving component 22 is described in further detail below, such as... Figure 2 As shown, the second drive assembly 22 may include a second motor 221, which is electrically connected to the electronic control assembly 3; wherein, the second motor 221 may also be a variable frequency motor. The tensioner assembly 2 may further include a second brake 24, which is electrically connected to the electronic control assembly 3. Thus, the electronic control assembly can control the second motor to drive the tensioner body, or it can control the second brake to brake the tensioner body, thereby controlling the rotational speed of the tensioner body.

[0061] Furthermore, such as Figure 2 As shown, the cable reeling and releasing device provided in this embodiment of the application, in Figure 1 Based on the cable winding and unwinding device shown, the second support assembly 21 can be further subdivided. For example, the second support assembly 21 may include: a first clamping plate support 211 and a second clamping plate support 212. One end of the tensioner body 23 can be connected to the first clamping plate support 211, and the other end of the tensioner body 23 can be connected to the second clamping plate support 212.

[0062] The first clamping plate bracket 211 may include a support portion and a shaft portion, wherein the shaft portion is connected to the support portion and extends relative to the support portion; the second clamping plate bracket 212 may also include a support portion and a shaft portion, wherein the shaft portion is connected to the support portion and extends relative to the support portion.

[0063] It is understood that the tensioner body 23 can be disposed between the shaft portion of the first clamping plate bracket 211 and the shaft portion of the second clamping plate bracket 212. That is, one end of the tensioner body 23 can be connected to the shaft portion of the first clamping plate bracket 211, and the other end of the tensioner body 23 can be connected to the shaft portion of the second clamping plate bracket 212.

[0064] Optionally, in one embodiment of this application, the second drive assembly 22 may further include: a second reducer 222 and a second clutch 223; the output shaft of the second motor 221 may be connected to the input shaft of the second reducer 222, the output shaft of the second reducer 222 may be connected to the input end of the second clutch 223, and the output end of the second clutch 223 may be connected to the shaft portion of the first clamping plate bracket 211; wherein, the second motor 221, the second reducer 222, and the second clutch 223 may all be mounted on the support portion of the first clamping plate bracket 211. Thus, the tensioner body can be controlled to rotate through the cooperation of the second motor, the second reducer, and the second clutch.

[0065] Optionally, in one embodiment of this application, such as Figure 2 As shown, the second brake 24 can be mounted on the support portion of the second clamping plate bracket 212 and can be connected to the shaft portion of the second clamping plate bracket 212. The second brake 24 can also be a magnetic powder brake. Thus, by mounting a second brake on the second clamping plate bracket, the tensioner body can be braked, thereby controlling the rotational speed of the tensioner.

[0066] The cable winding and unwinding device provided in this application embodiment can control the first drive component and the second drive component through the electronic control component during the cable winding process, thereby driving the drum body and the tensioner body and controlling the rotation speed of the drum body and the tensioner body; during the cable unwinding process, the first brake and the second brake can be controlled through the electronic control component to brake the drum body and the tensioner body and control the rotation speed of the drum body and the tensioner body.

[0067] To further illustrate the specific locations of the various components in the cable winding and unwinding device, in one embodiment of this application, as shown... Figure 3 As shown, Figure 3 The following is a structural side view of a cable winding and unwinding device provided in an embodiment of this application. The structural side view may include, by way of example, a roller body 14, a base 111, a first bracket 112, a first motor 131, a first reducer 132, a first clutch 133, a first clamping plate bracket 211, a second drive assembly 22, a tensioner body 23, a tension detection sensor 41, a sensor base 42, and a pitch platform 43.

[0068] It is important to understand that Figure 3 This is a structural side view of the cable winding and unwinding device viewed from one side of the first bracket 112 towards the side of the second bracket 113. Therefore, the second bracket 113, the linear module 114, the adjustment component 12, the first brake 15, the second clamping plate bracket 212, the second brake 24, etc. are not shown in this figure.

[0069] like Figure 3 As shown, the roller assembly 1 and the tensioner assembly 2 can be mounted on a single base, meaning that the tensioner assembly 2 can also be mounted on the base 111.

[0070] It is understandable that, such as Figure 3 As shown, when the cable winding and unwinding device is winding up the cable, the tension detection sensor 41 can be positioned between the roller assembly 1 and the tensioner assembly 2; at this time, the pitch platform 43 can be fixedly connected to the first bracket 112. It should be understood that the fixed connection between the pitch platform 43 and the first bracket 112 is only one example and is not intended to be limiting. For example, in another example, the pitch platform 43 can also be directly fixedly connected to the base 111.

[0071] Additionally, it should be understood that the height of the tension detection sensor 41 can be set according to the height of the roller body 14 and the tensioner body 23, as long as the cable between the roller body 14 and the tensioner body 23 can contact the tension detection sensor 41, and no limitation is made here.

[0072] The cable winding and unwinding device provided in this application embodiment can control the first drive component and the second drive component through the electronic control component, thereby driving the drum body and the tensioner body. That is, the electronic control drive of the electronic control component replaces the existing hydraulic drive, thereby reducing the space occupied by the drive device in the existing hydraulic drive method and avoiding the leakage of hydraulic oil and pollution of the environment by using the hydraulic drive method.

[0073] Figure 4 This is a structural block diagram of the electrical control component in a cable winding and unwinding device provided in an embodiment of this application.

[0074] like Figure 4 As shown, the electronic control component 3 may include a processor 31 and a frequency converter 32. The processor 31 and the frequency converter 32 may be connected together, and the frequency converter 32 may be electrically connected to the first drive component 13 and the second drive component 22 respectively.

[0075] In this way, the frequency converter can be controlled by the processor, which in turn controls the first drive assembly and the second drive assembly to drive the drum body and the tensioner body, reducing the space occupied by the drive device and avoiding the leakage of hydraulic oil and environmental pollution caused by hydraulic drive.

[0076] Optionally, in one embodiment of this application, the electronic control component 3 may specifically include: a host computer module and a control module. The host computer module may include: a touch screen and / or a personal computer (PC); the control module may include: a communication unit, a central processing unit (CPU) unit, a digital input / output unit, an analog input / output unit, and a frequency converter.

[0077] In this context, the host computer (or upper-level computer) is the computer that can directly issue control commands, typically a PC screen displaying various signal changes (hydraulic pressure, water level, temperature, etc.). The lower-level computer (or lower-level computer) is the computer that directly controls the equipment and obtains its status; it's usually a Programmable Logic Controller (PLC) or a microcontroller. Commands issued by the host computer are first sent to the lower-level computer, which then interprets these commands into corresponding timing signals to directly control the relevant equipment. The lower-level computer can convert the read equipment status data (usually analog) into digital signals and feed them back to the host computer. Conceptually, the controller and service provider are the host computer, while the controlled and serviced are the lower-level computers—a relationship similar to master and slave. However, the roles of host and lower-level computers are interchangeable; both require programming and have dedicated development systems.

[0078] The touchscreen can be a local control component, which can monitor the current operating status and set operating parameters; the PC can be a remote control component with the same function as the touchscreen, or a programming configuration component, which can reprogram the control module and the touchscreen, and reconfigure the frequency converter.

[0079] PC refers to a multi-purpose computer of a size, price, and performance suitable for personal use. Desktop computers, laptops, mini-laptops, tablets, and ultrabooks all fall under the category of personal computers. The CPU serves as the core of a computer system for computation and control, and is the final execution unit for information processing and program execution. A PLC is a digital electronic system specifically designed for industrial applications. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations, controlling various types of machinery or production processes through digital or analog input / output.

[0080] It is understood that the touch screen can be electrically connected to the communication unit, and the communication unit, the digital input / output unit, the analog input / output unit, and the frequency converter can all be electrically connected to the CPU unit, and the analog input / output unit can be electrically connected to the frequency converter.

[0081] Furthermore, the electric push rod 121, the limit switch 122, and the linear displacement sensor 123 in the adjustment assembly 12 can all be electrically connected to the digital input / output unit; the first motor 131 in the first drive assembly 13 and the second motor 221 in the second drive assembly 22 can all be electrically connected to the frequency converter; the first brake 15, the second brake 24, and the tension detection sensor 41 can all be electrically connected to the analog input / output unit.

[0082] To make it easier to understand, here is an example:

[0083] For example, the touch screen and PC of the host computer module in the electronic control component 3 can be connected to the communication unit of the control module through a network cable or serial communication line to complete data interaction; the analog input / output unit can be connected to the frequency converter 32, and control the output of the frequency converter 32 by outputting analog signals, thereby controlling the speed and torque of the first motor 131 and the second motor 221; the electric push rod 121 can be controlled by the digital input / output unit to push the second bracket 113 to move, and the start and stop of the electric push rod 121 can be controlled by the output digital signal; the signal detected by the limit switch 122 can be transmitted to the digital input / output unit, and can be used as an adjustment reference variable in the adjustment preparation process; the signal detected by the linear displacement sensor 123 can be transmitted to the digital input / output unit, and can be used as an adjustment reference variable in the adjustment preparation process; the tension detection sensor 41 can detect the cable tension during the detection process and transmit the signal to the analog input / output unit; the first brake 15 and the second brake 24 can be connected to the analog input / output unit, and the analog signal output by the analog input / output unit can control the magnitude of the braking torque.

[0084] The cable winding and unwinding device provided in this application embodiment can control the first drive component and the second drive component through the electronic control component, thereby driving the drum body and the tensioner body. That is, the electronic control drive of the electronic control component replaces the existing hydraulic drive, thereby reducing the space occupied by the drive device in the existing hydraulic drive method and avoiding the leakage of hydraulic oil and pollution of the environment by using the hydraulic drive method.

[0085] This application also provides a cable winding and unwinding method, which can be applied to the cable winding and unwinding device provided in this application. The cable winding and unwinding method provided in this application can be executed by the electrical control component 3 in the cable winding and unwinding device.

[0086] Figure 5 A flowchart illustrating a cable deployment and retrieval method provided in an embodiment of this application. Figure 5 As shown, the cable deployment and retraction method may include:

[0087] Step 510: Determine the working status of the cable reeling and releasing device.

[0088] The cable winding and unwinding device can be in the winding state, the unwinding state, or the state of installing the roller body.

[0089] Step 520: If the cable winding and unwinding device is in the winding state, obtain the winding parameters, which include the first winding parameter and the second winding parameter.

[0090] It should be understood that the cable winding parameters can be set according to actual working conditions and are not limited here. For example, if a 1-kilometer-long cable needs to be wound up within 1 hour, the appropriate rotational speed required for the cable winding device to complete the winding is calculated, and this rotational speed is the winding parameter. For example, the first winding parameter can be the rotational speed of the first motor, and the second winding parameter can be the rotational speed of the second motor.

[0091] Step 530: Control the first drive assembly to drive the roller assembly according to the first cable take-up parameters through the electronic control assembly, and control the second drive assembly to drive the tensioner assembly according to the second cable take-up parameters through the electronic control assembly.

[0092] Understandably, the operator can input the cable winding parameters through the touch screen in the electronic control component, and the touch screen can transmit the parameters to the control module. The control module can convert the first cable winding parameter into the rotational speed of the first motor of the first drive component in the roller assembly, and can also convert the second cable winding parameter into the rotational speed of the second motor of the second drive component in the tensioner assembly, thereby controlling the output of the frequency converter to drive the roller assembly and the tensioner assembly.

[0093] Step 540: If the cable release and take-up device is in the cable release state, the first drive component and the second drive component are controlled to stop working by the electronic control component.

[0094] It is understood that the first drive component and the second drive component stopping operation can be achieved by: the first motor and the second motor stopping, and the first clutch and the second clutch disengaging.

[0095] The cable winding and unwinding method provided in this application embodiment can determine the working state of the cable winding and unwinding device, and control the first drive component and the second drive component through the electronic control component under different working states, thereby driving the drum body and the tensioner body. That is, the electronic control drive of the electronic control component replaces the existing hydraulic drive, thereby reducing the space occupied by the drive device in the existing hydraulic drive method and avoiding the leakage of hydraulic oil and environmental pollution caused by the hydraulic drive method.

[0096] Optionally, in one embodiment of this application, the cable reeling-in / deeling method may include:

[0097] When the cable winding and unwinding device includes a first brake and a second brake, if the working state of the cable winding and unwinding device is the cable unwinding state, the cable unwinding parameters are obtained, and the cable unwinding parameters include the first cable unwinding parameters and the second cable unwinding parameters.

[0098] The electronic control component controls the first brake to adjust the cable tension of the drum assembly according to the first cable release parameters, and the electronic control component also controls the second brake to adjust the cable tension of the tensioner assembly according to the second cable release parameters.

[0099] Understandably, when the cable reeling / unwinding device is in the cable unwinding state, the first and second motors stop, and the first and second clutches disengage. At this time, the cable tension of the roller assembly and tensioner assembly can be adjusted by operating the first and second brakes.

[0100] The cable release parameters can be set according to actual working conditions and are not limited here. For example, the first cable release parameter can be a constant cable tension value required by the roller assembly, and the second cable release parameter can be a constant cable tension value required by the tensioner assembly. Specifically, the operator can input the cable release parameters through the touch screen in the electronic control component. The touch screen can transmit the parameters to the control module. The control module can convert the first cable release parameter into the braking torque of the first brake, and the second cable release parameter into the braking torque of the second brake, and output analog signals to control the torque of the first and second brakes to adjust the cable tension of the roller assembly and the tensioner assembly.

[0101] In this way, when the cable release device is releasing the cable, the first brake and the second brake can be controlled by the electronic control component, thereby adjusting the cable tension of the roller assembly and the tensioner assembly.

[0102] Optionally, in one embodiment of this application, before determining the operating state of the cable reel-in / deel-out device, the method may further include:

[0103] When the first support assembly includes a first support and a second support, the distance between the first support and the second support of the roller assembly is adjusted by the electronic control assembly;

[0104] During the process of adjusting the distance between the first support and the second support, the roller body of the roller assembly is placed between the first support and the second support.

[0105] It is understood that the specific process of adjusting the distance between the first support and the second support of the roller assembly through the electronic control component can be as follows: the size of the roller body of the roller assembly is input through the touch screen, and the digital input / output unit in the electronic control component can convert the size of the roller body into an output digital signal and control the electric push rod to retract; during the retraction of the electric push rod, it can be determined whether the limit switch is triggered; if so, the electric push rod can be stopped by the digital input / output unit; if not, the distance between the first support and the second support can be detected by the linear displacement sensor; then it can be determined whether the distance between the first support and the second support matches the roller size; if so, the electric push rod can be stopped by the digital input / output unit; if not, the electric push rod can be continued to retract by the digital input / output unit until the roller body of the roller assembly can be stably fixed between the first support and the second support.

[0106] In this way, before determining the working status of the cable winding and unwinding device, the adjusting component is controlled by the electronic control component, thereby adjusting the distance between the first and second supports of the roller assembly.

[0107] The following section provides a more detailed description of the specific implementation methods of the cable release and take-up method provided in this application embodiment, taking into account actual application scenarios.

[0108] For example, the cable winding and unwinding device corresponding to the cable winding and unwinding method provided in this application embodiment can be applied to the daily laying of cables and may include the following steps:

[0109] The first step is to install the roller body 14. Installing the roller body 14 can be the process of fixing a roller fully wound with cables or an empty roller that needs to be wound with cables onto the roller assembly 1. The touch screen in the electrical control assembly 3 can operate the electric push rod 121 to fully extend, thereby pushing the second bracket 113 to its farthest position; then, loading equipment such as cranes or overhead cranes can be used to load the roller body 14 onto the first bracket assembly 11. Then, the axial length of the roller body 14 can be measured and input into the relevant parameter position of the touch screen; the touch screen transmits the parameter to the control module, which can control the electric push rod 121 to retract. At this time, the linear displacement sensor 123 can detect the distance between the first bracket 112 and the second bracket 113 in real time and feed the distance value back to the control module. When the distance meets the installation requirements of the roller body 14, the control module can control the electric push rod 121 to stop. During the retraction of the electric push rod 121, the limit switch 122 can detect whether there are obstacles or workpieces inside the second bracket 113. When the limit switch 122 is triggered, it is determined that there is an obstacle, and the electric push rod 121 can stop retracting, thereby avoiding damage to the second bracket 113 and the electric push rod 121. It can also prevent the electric push rod 121 from retracting too much and crushing the roller body 14 if the linear displacement sensor 123 is damaged.

[0110] The second step is the cable winding process. This process involves winding the external cable around the drum body 14. In this case, the drum assembly 1 and tensioner assembly 2 are the driving devices, and the external cable to be wound is the driven device. The drum assembly 1 can move at a constant speed according to a set value to ensure the cable winding speed. The tensioner assembly 2 can adjust the actual operating speed of the variable frequency motor according to the required speed and cable tension. The touchscreen in the electrical control assembly 3 can select the cable winding operation. At this time, the first clutch 133 and the second clutch 223 on the drum assembly 1 and tensioner assembly 2 can be engaged, and the first brake 15 and the second brake 24 can be deactivated. The touchscreen can then input the cable winding speed and the inner diameter of the drum body 14. The touchscreen transmits the parameters to the control module, which can convert the parameters into the rotational speeds of the first motor 131 of the drum assembly 1 and the second motor 221 of the tensioner assembly 2, thereby controlling the output of the variable frequency drive 32. During the cable winding process, a tension detection sensor 41 can be installed between the drum assembly 1 and the tensioner assembly 2 to detect the tension in real time and adjust the rotational speed of the tensioner body 23.

[0111] The third step is the cable release process. This process involves winding the cable on the drum body 14 onto external equipment. In this case, the drum assembly 1 and tensioner assembly 2 are the driven devices, while the external cable take-up device is the driving device. The touchscreen in the electrical control assembly 3 can select the cable release operation. At this time, the first clutch 133 and the second clutch 223 on the drum assembly 1 and tensioner assembly 2 can be disengaged, and the first brake 15 and the second brake 24 can operate. The touchscreen can then input cable release parameters, which are transmitted to the control module. The control module converts the cable release parameters into the braking torque of the second brake 24 and outputs an analog signal to control the torque magnitude. During the cable release process, a tension sensor 41 can be installed between the tensioner assembly 2 and the external cable take-up device to detect tension in real time and adjust the braking torque of the second brake 24. To ensure that the cable wound by the tensioner assembly 2 does not become tangled or even loose, the first brake 15 of the drum assembly 1 also needs to have a certain braking torque, which can be controlled by the analog signal output by the analog input / output unit.

[0112] The cable winding and unwinding method applied to the cable winding and unwinding device provided in the embodiments of this application can determine the working state of the cable winding and unwinding device, and control the first drive component and the second drive component through the electronic control component under different working states, thereby driving the drum body and the tensioner body. That is, the electronic control drive of the electronic control component replaces the existing hydraulic drive, thereby reducing the space occupied by the drive device in the existing hydraulic drive method and avoiding the leakage of hydraulic oil and pollution of the environment by using the hydraulic drive method.
