In conclusion, the horizontal high-voltage cable unwinding machine control system based on the intelligent hydraulic control technology has the advantages of high automation degree and high universality.
The telescopic cross beam 11 and/or the telescopic longitudinal beam 12 are/is provided with at least one group of roller assemblies 13 so as to support the winding reel 01 and drive the winding reel 01 to rotate, and the paying-off of the cable 02 is realized. When the width and the length of the pay-off bracket 1 are changed, the distance between two adjacent roller assemblies 13 is changed, so that the distance between the adjacent roller assemblies 13 is matched with the outer diameter and the length of the winding reel 01. Specifically, two sets of roller assemblies 13 are included in this embodiment, and the two sets of roller assemblies 13 are symmetrically disposed at two ends of the telescopic longitudinal beam 12, each set of roller assemblies 13 includes two rollers, two roller supports fixedly disposed on the pay-off bracket 1, and a roller driving member for driving the rollers to rotate, and each roller support is used for supporting one roller to rotate. Of course, the roller assemblies 13 may be provided on the telescopic beam 11, and the structure of the roller assemblies 13 is not limited thereto.
The roller assembly 13 includes a roller for abutting against the winding reel 01, and an anti-slip layer is fixedly disposed on the periphery of each roller so as to increase the friction force between the roller and the winding reel 01, thereby ensuring that the roller can stably drive the winding reel 01 to rotate and having high reliability. The anti-skid layer can be embossing fixedly arranged on the periphery of the roller and can also be made of protective materials coated on the periphery of the roller.
In order to improve the safety, two ends of each roller are provided with limit flanges, the two limit flanges are respectively abutted against support flanges at two ends of the winding reel 01, specifically, the inner end faces of the limit flanges are abutted against the outer end faces of the support flanges, the winding reel 01 is prevented from being separated from the rollers in the rotating process, and the safety is naturally improved. The inner end surface of the stopper flange refers to an end surface of the stopper flange on the side closer to the spool 01.
The invention also comprises a wire arranging device 2 which is arranged opposite to the paying-off bracket 1, wherein the wire arranging device 2 can be used for tensioning the cable 02 and guiding the cable 02 to move.
In order to ensure that the cable 02 wound on the winding reel 01 can keep proper tension during the paying-off process, the invention also comprises a tension detection device for detecting the tension of the cable 02. The tension detecting means may be a tension sensor, but the type of the tension detecting means is not limited thereto, and reference may be made to the related art in particular. In addition, the control device is respectively connected with the tension detection device and the roller assembly 13, so that the control device adjusts the rotating speed and the steering of the roller assembly 13 according to the signal sent by the tension detection device until the tension of the cable 02 is equal to the preset tension. The predetermined tension here refers to the force to which the cable 02 is subjected while maintaining the proper tension.
Specifically, assuming that the winding reel 01 rotates counterclockwise as a paying-off state, when the tension detecting device detects that the tension of the cable 02 is less than a preset tension, it means that the cable 02 between the winding reel 01 and the winding displacement device 2 is too loose, and at this time, the tension detecting device sends a signal to the control device, and the control device controls the roller assembly 13 to reduce the rotation speed, or controls the roller assembly 13 to rotate clockwise by a proper angle, until the tension of the cable 02 is equal to the preset tension; on the contrary, when the tension of the cable 02 is greater than the preset tension, the tension detecting device sends a signal to the control device, and the control device controls the roller assembly 13 to increase the rotating speed, so as to prevent the cable 02 between the winding reel 01 and the winding displacement device 2 from being excessively tensioned, and the tension of the cable 02 is equal to the preset tension. From this accessible tension detection device and controlling means automatically regulated cable 02's tensioning degree, the security is higher, and degree of automation is high.
Preferably, the cable arranging device 2 comprises a cable arranging bracket 21 and a cable arranging assembly 22, wherein the cable arranging assembly 22 is mounted on the cable arranging bracket 21, and the cable arranging assembly 22 slides along the cable arranging bracket 21 along with the cable 02. In order to make the flat cable assembly 22 slide stably, a guide assembly for guiding the flat cable assembly 22 to slide is further arranged between the flat cable assembly 22 and the flat cable support 21, the guide assembly comprises a guide rack arranged in an installation groove of the flat cable support 21 and a guide gear arranged at the bottom of the flat cable assembly 22, and the guide rack is meshed with the guide gear, so that the guide rack can be used for driving the flat cable assembly 22 to move and guiding the flat cable assembly 22 to move.
Preferably, the present invention further comprises a linear velocity detection device connected to the control device, and the linear velocity detection device may be a velocity detection sensor. The control device adjusts the linear velocity of the wire arranging assembly 22 according to the signal sent by the linear velocity detection device until the linear velocity is matched with the rotating speed of the roller assembly 13. It should be noted that the paying-off speed and the tension of the cables 02 with different specifications are different, and accordingly, the linear speed of the cable arranging assembly 22 which is changed within a certain range is alternatively matched with the linear speed of the cables 02 with different specifications when the rotating speed of the roller assembly 13 is fixed, so as to adapt to the cables 02 with different specifications. For example, when the winding reel 01 rotates at 5r/min, the linear velocity of the traverse assembly 22 is 5m/s for the cable 02 having an outer diameter of 50 mm; however, for a cable 02 having an outer diameter of 40mm, the linear velocity of the flex assembly 22 is 4 m/s. For cables 02 with different specifications, the rotation speed of the winding reel 01 and the linear velocity of the winding displacement assembly 22 can be input into the control device in advance, when the linear velocity detection device detects that the linear velocity of the winding displacement assembly 22 is inconsistent with the preset linear velocity, the linear velocity detection device sends a signal to the control device, and after the control device judges and analyzes the signal, the control device correspondingly increases or decreases the linear velocity of the winding displacement assembly 22. Specifically, the cable assembly 22 includes a cable driving member for driving the cable assembly 22 to move, the cable driving member is connected to the control device, and the cable driving member may be a hydraulic motor or an electric motor, so that the control device adjusts the linear velocity of the cable assembly 22 by adjusting the rotation speed of the cable driving member. Obviously, the key improvement of the present invention is that the control means combines the line speed detecting means with the traverse driving member.
The present invention further includes a braking device connected to the control device and the roller assembly 13, respectively, and a rotational speed detecting device connected to the control device and detecting a rotational speed of the spool 01. The structure of the braking device may refer to an existing braking device, and the rotation speed detecting device is preferably an encoder, but is not limited thereto. The control device starts the braking device to control the roller assembly 13 to stop rotating when the rotating speed of the winding reel 01 exceeds the maximum rotating speed according to the signal sent by the rotating speed detection device. Specifically, when the rotation of the winding reel 01 is abnormal, the rotation speed of the winding reel 01 may exceed the maximum rotation speed, and at this time, the rotation speed detecting device sends a signal to the control device, the control device compares the current rotation speed with the maximum rotation speed, and when the current rotation speed is greater than the maximum rotation speed, the control device starts the braking device to brake the roller assembly 13. It should also be noted that a key improvement of the invention is that the control means combines the rotation speed detection means and the braking means.

In this embodiment, the state detecting device may be an encoder for detecting the rotation speed of the power driving device, and may also be a torque detector for detecting the torque of the power driving device, which is not particularly limited herein.
In the starting stage, when the state detection device detects that the running state of the power driving device is normal, the state detection device sends a signal to the control device, and the control device controls the power driving device to normally run; otherwise, the control device controls the power driving device to stop rotating, so that abnormal operation of the subsequent device is avoided, the automation degree is high, and the working reliability is high.
The invention also comprises a gripping device for gripping the reel 01 and an outer diameter detection device for detecting the reel 01, wherein the gripping device is preferably an industrial robot capable of bearing heavy loads, and the specific structure of the industrial robot can refer to the prior art. The outer diameter detecting means may be an outer diameter detector, but is not limited thereto.
