Description

Technical Field

[0001] The utility model relates to the field of ship cable installation, in particular to an adaptive cable feeding system. Background Art

[0002] During the ship construction process, power construction is a very important and difficult construction besides the infrastructure construction. In the ship construction, the cable is the power blood vessel and control nerve of the entire ship. It is very important to ensure the construction quality of the cable and prevent the cable from being damaged during the construction process.

[0003] During the on-site construction process, people walk forward while pulling cables. The walking speed varies depending on the person and the on-site conditions. Therefore, in the prior art, cable transportation suffers from human factors causing damage to the cable surface during the pulling process and the copper wire diameter inside the cable becoming smaller due to tension, which affects the operating current. In addition, 2-3 people are often required to pull the cable, which wastes manpower and there are problems with the division of labor and coordination among personnel, affecting work efficiency. Utility Model Content

[0004] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide an adaptive cable feeding system to achieve the purpose of reducing labor intensity and improving work efficiency.

[0005] The utility model protects an adaptive cable wire feeding system, comprising a cable tensioner, a control end, a tension motor, a tension sensor and a cable wire feeding motor; the cable wire feeding motor drives the cable tensioner; the control end comprises a data storage module, a wire feeding speed adjustment module, a tension adjustment module and a data acquisition module; the control end calculates the tension value required for cable stretching by using the data of the tension sensor collected by the data acquisition module, and compares the tension value with different cable safety tensions recorded in the data storage module inside the control end, confirms the target tension value, and uses the tension adjustment module to control the tension motor to adjust the tension value to the target tension value.

[0006] The cable feeding motor is installed on the cable drum bracket and cooperates with the reducer to provide power for cable pulling. It also adjusts the speed of active cable feeding in real time according to the workers' pulling speed.

[0007] The tension motor adjusts the tension angle in real time according to the tension value calculated by the main controller.

[0008] When the line tension is uncertain, the tension sensor detects the pulling tension value in real time to provide a basis for calculating the tension value required for the cable.

[0009] Furthermore, the control end includes a main controller and an auxiliary controller, and the auxiliary controller is used to collect signals from the cable tensioner and the tension sensor and process the data, and then transmit the data to the main controller.

[0010] The main controller integrates the cable feeding speed and tension adjustment PID algorithm, namely the feeding speed adjustment module and the tension adjustment module, which are the core of the system. The main controller calculates the tension required for cable stretching through the front-end signal collected by the auxiliary controller, and compares the tension value with the safe tension of different cables in the database inside the controller to confirm the optimal tension, and controls the tension motor to adjust the tension value to the appropriate tension value.

[0011] The cable tensioner is a manual cable tensioner with an integrated tension device and alarm device. It provides auxiliary power for the manual cable pulling process and provides an alarm function when the tension is too large to ensure the safety of the cable.

[0012] Furthermore, it also includes an angle sensor; the angle sensor is communicatively connected to the auxiliary controller; the main controller determines the wire pulling speed based on the signal of the angle sensor collected in real time by the auxiliary controller, so as to adjust the speed of the cable feeding motor in real time.

[0013] The main controller also needs to collect the angle sensor signal in real time through the auxiliary controller, determine the wire pulling speed, and adjust the speed of the wire feeding motor in real time to ensure that the wire feeding motor speed is too fast or too slow during the wire pulling process, resulting in excessive cable tension or the wire dragging on the ground. The auxiliary controller collects sensor data such as angle sensors, tension sensors, and manual cable tensioners, processes the data, and transmits the sensor values ​​to the main controller to ensure that the main controller can control the cable feeding motor in real time, and that the main controller can calculate and control the tension motor and the cable feeding motor at the ms level, while reducing the performance requirements of the main controller and improving the response speed of the main controller.

[0014] Furthermore, the cable tensioner includes a seat body, and a cable drum and a wire retractor mounted on the seat body; the cable feeding motor drives the cable drum to rotate to achieve cable retraction and release; the cable passes through the wire retractor and is wound around the cable drum.

[0015] The seat body plays the role of bearing and installing structural parts. The cable retractor can realize the delivery and retraction of cables.

[0016] Furthermore, the cable retractor includes a fixed pulley group, a movable shaft, and a first spring and a second spring; the fixed pulley group is installed at a lower corner of the base body; the movable shaft is fixedly connected to the fixed pulley group; the first spring and the second spring are respectively arranged on both sides of the movable shaft; the cable is passed through the fixed pulley group; by retracting and releasing the cable, the movable shaft squeezes the first spring or the second spring, and then the first spring or the second spring is used to realize automatic retraction and release of the cable.

[0017] Furthermore, the fixed pulley block includes a first fixed pulley and a second fixed pulley installed horizontally; the movable shaft is fixed on the second fixed pulley, and the angle between the movable shaft and the horizontal plane is 30 to 60 degrees. Preferably, the angle between the movable shaft and the horizontal plane is 45 degrees.

[0018] Furthermore, the first spring and the second spring are respectively perpendicular to the movable axis.

[0019] Preferably, the first spring and the second spring are on the same straight line.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The utility model system controls the wire feeding motor to drive the cable drum to rotate actively, and improves the passive rotation of the cable drum to stretch the cable into an elastic active cable feeding, which reduces the labor intensity of workers. In the traditional cable pulling, 2-3 people are often needed. After using this system, one person can easily pull and release the cable, thereby improving work efficiency.

[0022] The utility model combines an algorithm module and, through a tension algorithm, ensures the stability of the cable pulling force during the cable unwinding process, while eliminating the need for one person to unwind and the other to pull the cable during pulling, which may cause the tension to increase or the cable surface to be damaged during pulling due to unsynchronized speeds.

[0023] The utility model integrates different types of cable tension meters inside the main controller as auxiliary models. During the cable laying process, the cable model and the tension that needs to be set can be confirmed by comparing the teaching tension with the cable tension meter, and the recovery of the pulled cables can be achieved by reversing the cable feeding motor, thereby reducing cable loss.

[0024] During construction, workers will measure the required length of the cable in advance and enter the cable length into the system in advance. The system will calculate the stretched length of the cable based on the motor to save materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Example

[0034] This embodiment demonstrates the adaptive cable feeding system and working process of the utility model.

[0035] An adaptive cable feeding system, such as Figures 1 to 3As shown, it includes a cable tensioner, a control end, a tension motor, a tension sensor and a cable feeding motor; the cable feeding motor drives the cable tensioner; the control end includes a data storage module, a feeding speed adjustment module, a tension adjustment module and a data acquisition module; the control end uses the data of the tension sensor collected by the data acquisition module to calculate the tension value required for cable stretching, and compares the tension value with the different cable safety tensions recorded in the data storage module inside the control end, confirms the target tension value, and uses the tension adjustment module to control the tension motor to adjust the tension value to the target tension value.

[0036] The control end includes a main controller and an auxiliary controller. The auxiliary controller is used to collect signals from the cable tensioner and the tension sensor, process the data, and then transmit the data to the main controller.

[0037] The adaptive cable feeding system also includes an angle sensor; the angle sensor is communicatively connected to the auxiliary controller; the main controller determines the wire pulling speed based on the signal of the angle sensor collected in real time by the auxiliary controller, so as to adjust the speed of the cable feeding motor in real time.

[0038] Combination Figures 4-5 As shown, the cable tensioner includes a seat body 1, and a cable drum 2 and a wire retractor installed on the seat body 1; the cable feeding motor drives the cable drum 2 to rotate to realize the retraction and release of the cable; the cable passes through the wire retractor and is wound around the cable drum 2.

[0039] like Figure 5 As shown, the cable retractor includes a first fixed pulley 31, a second fixed pulley 32, a movable shaft 33, a first spring 34 and a second spring 35; the first fixed pulley 31 and the second fixed pulley 32 are horizontally installed at a lower corner of the seat body 1; the movable shaft 33 is fixed on the second fixed pulley 32, and the angle between the movable shaft 33 and the horizontal plane is 45°. The first spring 34 and the second spring 35 are respectively arranged on both sides of the movable shaft 33; the cable is passed between the first fixed pulley 31 and the second fixed pulley 32; by retracting and releasing the cable, the movable shaft 33 squeezes the first spring 34 or the second spring 35, and then the rebound force of the first spring 34 or the second spring 35 is used to realize the automatic retraction and release of the cable. The first spring 34 and the second spring 35 are respectively perpendicular to the movable shaft 33. And the first spring 34 and the second spring 35 are on the same straight line. The outer side of the seat body is also provided with an electromagnet 36 that can be used to fix the cable.

[0040] During the teaching of cable tension, the main controller controls the cable feeding motor to run at a low speed, the auxiliary controller collects the tension value of the sensor on the cable tensioner, and monitors the angle change of the angle sensor in real time. According to the angle change, the main controller quickly adjusts the tension motor. The main controller processes and calculates the signal collected by the auxiliary group controller, and converts and adjusts the tension motor in real time. When the feeding angle swings within 5° around the set angle, the teaching is completed. At this time, the angle value of the tension sensor is the tension value of the corresponding cable feeding. The main controller compares this tension value with the tension value in the system parameter table, and compares the tension values ​​of the set angles with the cable tension table values ​​for multiple times; let X be the tension value in the cable tension table, Xi be the tension value measured by the tension sensor each time the angle sensor measures at the set angle, S2 is the sample variance, according to the sample variance formula, when the S2 value is the smallest, it means that the cable setting value is closest to the cable model value, and the cable tension can be set to the tension value of this cable.

[0041]
