Further, as shown in fig. 2, the cable reel apparatus provided in the embodiment of the present invention may be added with other components, such as a tension detecting assembly, on the basis of the cable reel apparatus shown in fig. 1.

The tension detection sensor is an instrument used for measuring the tension value of the coiled material in the tension control process. The tension detection sensor can be divided into a strain gauge type and a micro-displacement type according to the principle, wherein the strain gauge type tension detection sensor is formed by connecting a tension strain gauge and a compression strain gauge together in a bridge mode, the resistance value of the strain gauge is changed when external pressure is applied, and the change value is in direct proportion to the magnitude of the applied tension; the micro-displacement type tension detecting sensor is a sensor that applies a load by an external force to displace a plate spring and then detects tension by a differential transformer, and is called a micro-displacement type tension detector because the displacement amount of the plate spring is extremely small. In addition, the external structure can be divided into: pivot type, through-pivot type, cantilevered type, etc. The strain gauge is an element for measuring strain, which is formed by a sensitive grid or the like. In order to make the strain gauge have a certain resistance value and not too long, the sensitive grid of the strain gauge is made into a grid shape by adopting a metal resistance wire with the diameter of 0.025 mm. The sensitive grid is the core of the strain gauge and is adhered to an insulated substrate, lead-out wires are welded at two ends of the sensitive grid, and a covering layer with a protection effect is adhered on the sensitive grid. The working principle of the resistance strain gauge is based on the strain effect, that is, when a conductor or a semiconductor material is mechanically deformed under the action of external force, the resistance value of the conductor or the semiconductor material is correspondingly changed, and the phenomenon is called the strain effect.

Thetension detecting sensor 41 may be disposed outside a range between the drum assembly 1 and thetensioner assembly 2 at a side close to thetensioner assembly 2 when the cable winding and unwinding device is performing the cable unwinding; at this time, thetension detecting assembly 4 may further include asensor mount 42, and thetension detecting sensor 41 may be disposed on thesensor mount 42.

In this way, in the cable winding process, the tension of the cable is detected in real time by arranging the tension detection sensor between the roller assembly and the tensioner assembly; during the cable laying process, the tension of the cable is detected in real time by providing a tension detecting sensor outside the range between the drum assembly and the tensioner assembly and at a side close to the tensioner assembly.

In applying the present invention, theelectric control assembly 3 in the cable winding and unwinding device may perform the following cable winding and unwinding method.

Fig. 5 is a flowchart of a cable winding and unwinding method according to an embodiment of the present application. As shown in fig. 5, the cable winding and unwinding method may include:

step 510, determining the operating state of the cable reel.

The working state of the cable winding and unwinding device can be a cable winding state or a cable unwinding state, and can also be a state of installing the roller body.

Step 520, if the working state of the cable winding and unwinding device is a cable winding state, cable winding parameters are obtained, and the cable winding parameters include a first cable winding parameter and a second cable winding parameter.

It should be understood that the cable retracting parameters may be set according to actual working conditions, and are not limited herein. For example, when a cable with a length of 1 kilometer needs to be wound in 1 hour, a proper rotation speed required by the cable winding and unwinding device to complete winding is calculated, and the rotation speed is the winding parameter. For example, the first cable-retracting parameter may be a rotating speed of the first inverter motor, and the second cable-retracting parameter may be a rotating speed of the second inverter motor.

And 530, controlling the first driving component to drive the roller component according to the first cable collection parameter through the electric control component, and controlling the second driving component to drive the tensioner component according to the second cable collection parameter through the electric control component.

It can be understood that the cable take-up parameters can be input by a worker through a touch screen in the electric control assembly, and the parameters can be transmitted to the control module through the touch screen; the control module can convert the first cable-winding parameter into the rotating speed of a first motor of a first driving assembly in the roller assembly, and can also convert the second cable-winding parameter into the rotating speed of a second motor of a second driving assembly in the tensioner assembly, so that the output of the frequency converter is controlled to drive the roller assembly and the tensioner assembly.

And 540, if the working state of the cable winding and unwinding device is a cable unwinding state, controlling the first driving assembly and the second driving assembly to stop working through the electric control assembly.

It is understood that the first drive assembly and the second drive assembly may be deactivated by: the first motor and the second motor are stopped, and the first clutch and the second clutch are disconnected.

The mooring rope winding and unwinding method provided by the embodiment of the application can control the first driving assembly and the second driving assembly through the electric control assembly respectively under different working states by determining the working states of the mooring rope winding and unwinding device, so as to drive the roller body and the tensioner body, namely, the electric control driving of the electric control assembly is utilized to replace the existing hydraulic driving, so that the occupied space of the driving device in the existing hydraulic driving mode is reduced, and the hydraulic oil leakage and environmental pollution caused by the hydraulic driving mode is avoided.

Optionally, in an embodiment of the present application, the cable reeling and unreeling method may include:

under the condition that the cable winding and unwinding device comprises a first brake and a second brake, if the working state of the cable winding and unwinding device is a cable unwinding state, cable unwinding parameters are obtained, wherein the cable unwinding parameters comprise a first cable unwinding parameter and a second cable unwinding parameter;

the first brake is controlled by the electronic control assembly to adjust the cable tension of the roller assembly according to the first cable laying parameter, and the second brake is controlled by the electronic control assembly to adjust the cable tension of the tensioner assembly according to the second cable laying parameter.

It is to be understood that in the case where the operating state of the cable retracting device is the cable releasing state, the first motor and the second motor are stopped, and the first clutch and the second clutch are disengaged. At this time, the cable tension of the drum assembly and the tensioner assembly may be adjusted by the operation of the first brake and the second brake.

The cable laying parameters may also be set according to actual working conditions, and are not limited herein. For example, the first payout parameter can be a desired constant cable tension value for the drum assembly, and the second payout parameter can be a desired constant cable tension value for the tensioner assembly. Specifically, the staff can input the cable laying parameters through a touch screen in the electric control assembly, and the touch screen can transmit the parameters to the control module; the control module can convert the first cable laying parameter into the braking torque of the first brake and convert the second cable laying parameter into the braking torque of the second brake, and output an analog quantity signal, so that the torque of the first brake and the torque of the second brake are controlled to adjust the cable tension of the roller assembly and the tensioner assembly.

Therefore, when the cable is released by the cable releasing and releasing device, the first brake and the second brake are controlled by the electric control assembly, and the tension of the cable of the roller assembly and the tensioner assembly is further adjusted.

Optionally, in an embodiment of the present application, before determining the operating state of the cable winding and unwinding device, the method may further comprise:

in the case that the first bracket assembly comprises a first bracket and a second bracket, the distance between the first bracket and the second bracket of the roller assembly is adjusted through the electric control assembly;

in adjusting the distance between the first bracket and the second bracket, the drum body of the drum assembly is placed between the first bracket and the second bracket.

It can be understood that, the specific process of adjusting the distance between the first bracket and the second bracket of the roller assembly through the electric control assembly can be as follows: the size of a roller body of the roller assembly is input through a touch screen, and a digital quantity input and output unit in the electric control assembly can convert the size of the roller body into an output digital quantity signal and control the electric push rod to retract; in the retraction process of the electric push rod, whether the limit switch is triggered or not can be judged; if yes, the electric push rod can be controlled to stop through the digital quantity input and output unit; if not, detecting the distance between the first support and the second support through a linear displacement sensor; then whether the distance between the first bracket and the second bracket is matched with the size of the roller can be judged; if yes, the electric push rod can be controlled to stop through the digital quantity input and output unit; if not, the electric push rod can be controlled to continuously retract through the digital quantity input and output unit; until the roller body of the roller assembly can be stably fixed between the first bracket and the second bracket.

Therefore, before the working state of the cable winding and unwinding device is determined, the electric control assembly controls the adjusting assembly, and then the distance between the first support and the second support of the roller assembly is adjusted.

The following describes in detail a specific implementation of the cable winding and unwinding device according to an embodiment of the present invention with reference to an actual application scenario.

For example, the cable winding and unwinding device provided by the embodiment of the utility model can be applied to daily cable laying, and can comprise the following steps:

in a first step, theroller body 14 is installed. Installation of thedrum body 14 may be a process of securing a full cable wound drum or an empty drum requiring cable winding to the drum assembly 1. The touch screen in theelectronic control assembly 3 can operate theelectric push rod 121 to fully extend, so as to push thesecond bracket 113 to the farthest position; theroller bodies 14 may then be loaded onto thefirst frame assembly 11 using a crane, or like loading device. Then, the axial length of theroller body 14 can be measured, and the axial length of theroller body 14 is input to the relevant parameter position of the touch screen; the touch screen transmits the parameters to the control module, and the control module can control theelectric push rod 121 to retract. At this time, thelinear displacement sensor 123 may detect the distance between thefirst bracket 112 and thesecond bracket 113 in real time, and feed back the distance value to the control module, and after the distance can meet the installation requirement of thedrum body 14, the control module may control theelectric push rod 121 to stop. In the retracting process of theelectric push rod 121, thelimit switch 122 can detect whether an obstacle or a workpiece exists inside thesecond bracket 113, when thelimit switch 122 is triggered, the obstacle is determined, theelectric push rod 121 can stop retracting, so that damage to thesecond bracket 113 and theelectric push rod 121 is avoided, and the phenomenon that theroller body 14 is damaged due to too large retracting amount of theelectric push rod 121 under the condition that thelinear displacement sensor 123 is damaged can also be avoided.

And step two, a cable collecting process. The process of reeling in the cable may be a process of winding the external cable around thedrum body 14, in which case the drum assembly 1 and thetensioner assembly 2 may be the driving device and the external device to be reeled in may be the driven device. The roller assembly 1 can move at a constant speed according to a set value, so that the cable collecting speed is ensured; thetensioner assembly 2 can adjust the operating speed of the actual variable frequency motor based on the desired speed and cable tension. The touch screen in theelectric control assembly 3 can select the cable retracting operation, thefirst clutch 133 and thesecond clutch 223 on the roller assembly 1 and thetensioner assembly 2 can be closed, and thefirst brake 15 and thesecond brake 24 can be out of operation. The touch screen can then enter the take-up speed and the inner ring diameter of theroller body 14; the touch screen transmits the parameters to the control module, which can convert the parameters into the rotational speeds of thefirst motor 131 of the drum assembly 1 and thesecond motor 221 of thetensioner assembly 2, thereby controlling the output of thefrequency converter 32. During the cable winding process, atension detecting sensor 41 can be installed between the drum assembly 1 and thetensioner assembly 2 to detect the tension in real time and adjust the rotating speed of thetensioner body 23.

And thirdly, a cable releasing process. The cable laying process may be a process of winding the cable on thedrum body 14 to an external device, in which case, the drum assembly 1 and thetensioner assembly 2 may be a driven device, and the external cable reeling device may be a driving device. The touch screen in theelectric control assembly 3 can select the cable laying operation, thefirst clutch 133 and thesecond clutch 223 on the roller assembly 1 and thetensioner assembly 2 can be disconnected, and thefirst brake 15 and thesecond brake 24 can be operated. The touch screen can then type in the payout parameters, the touch screen transmits the parameters to the control module, and the control module can convert the payout parameters into the brake torque of thesecond brake 24 and output an analog signal to control the torque. During the cable laying process, atension detecting sensor 41 may be installed between thetensioner assembly 2 and the external cable take-up device to detect tension in real time and adjust the braking torque of thesecond brake 24. In order to ensure that the cable wound by thetensioner assembly 2 is not disordered and even loosened, thefirst brake 15 of the roller assembly 1 is required to have a certain braking torque, and the torque can be controlled by an analog quantity signal output by an analog quantity input-output unit.

The cable winding and unwinding method applied to the cable winding and unwinding device provided by the utility model can control the first driving assembly and the second driving assembly through the electric control assembly so as to drive the roller body and the tensioner body, namely, the electric control driving of the electric control assembly is utilized to replace the existing hydraulic driving, so that the space occupied by the driving device in the existing hydraulic driving mode is reduced, and the hydraulic oil leakage caused by the hydraulic driving mode is avoided to pollute the environment.
