Description

[0002] Port cables are cables designed for various mechanical equipment in port environments. These cables need to withstand harsh working environments, frequent movements and mechanical stress. Modern ports pay more and more attention to automation and intelligence. As an important part of lifting equipment, winches can quickly and accurately lift cables, greatly improving the efficiency of port operations. In port environments, cables often need to be moved or adjusted frequently. The use of winches can significantly reduce the time and labor intensity of manual operations.

[0003] The existing port cables are relatively thick and heavy in weight. When the winch is laying the port cables, it is necessary to check the cable damage at any time. If the cable is found to be damaged or over-twisted, the operation must be stopped immediately and the cause must be found out. However, in the process of laying the cables, the existing manual inspection of the cable insulation not only results in low inspection efficiency, but is also prone to missed inspections.

[0050] A telescopic connection mechanism 6 is connected to the outer side of the rotating gear 42 and at a position deviated from the outer gear ring 41, and the telescopic connection mechanism 6 is connected to the fixing ring 3;

[0051] The telescopic connection mechanism 6 includes a moving frame 61 located outside the rotating gear 42, a rack 62 is fixedly installed on one side inside the moving frame 61, and the rotating gear 42 is meshed and connected with the rack 62;

[0053] Specific implementation process: when the positions between the multiple connection frames 43 are adjusted according to the positions of the outer insulation layer of the cable, the rotating motor 51 is operated to rotate one of the rotating gears 42, and when the rotating gear 42 rotates, it drives the outer gear ring 41 to rotate around the fixed ring 3, and when the outer gear ring 41 rotates, it drives the remaining rotating gears 42 to rotate synchronously, so that the multiple rotating gears 42 rotate synchronously at the fixed ring 3, and then the rotating gear 42 is engaged with the rack 62 at the moving frame 61 close to it, and the moving frame 61 is further moved toward each other under the limiting action of the guide plate 63, until the detection ends of the detection members 7 at the multiple connection frames 43 are all moved to the outside of the outer insulation layer of the cable, and then the rotating motor 51 stops moving;

[0054] The connection frame 43 is connected to the detection member 7. The multiple detection members 7 are used to detect the damage of the outer insulation layer of the cable. The center of the combination of the multiple detection members 7 can be used for the cable to pass through.

[0055] The detection member 7 includes a connection sleeve 71 slidably connected to the connection frame 43, a moving opening is provided on the connection frame 43 and at a position corresponding to the connection sleeve 71, two first connection ears 72 are fixedly installed on the outer side of the connection sleeve 71, and a connection member 73 is installed between the two first connection ears 72 and the connection frame 43, and the connection member 73 is used to detect the position of the connection sleeve 71;

[0056] The connecting member 73 includes two slide bars 731 fixedly mounted in parallel on the connecting frame 43, and the two first connecting ears 72 are respectively slidably sleeved on the outside of the corresponding slide bars 731, and the two sides of the two first connecting ears 72 are respectively fixedly connected with connecting springs 732, and the connecting springs 732 are sleeved on the outside of the slide bars 731;

[0057] A detection plate 733 is fixedly connected between two connecting springs 732 that are parallel to each other and located on the same side and close to one end of the connecting frame 43. The detection plate 733 is slidably sleeved on the outside of the two sliding rods 731. A pressure sensor 734 is installed between the detection plate 733 and the connecting frame 43, and a buzzer 735 is installed on the connecting frame 43.

[0058] A fixed sleeve 74 is fixedly passed through the connecting sleeve 71, and a first telescopic tube 75 is connected to the fixed sleeve 74 and one end close to the cable, and a detection tube 76 is connected to the end of the first telescopic tube 75 away from the fixed sleeve. A spherical groove is provided at the bottom of the detection tube 76, and a detection ball 77 is passed through the spherical groove, and the detection ball 77 is rotatably connected to the spherical groove;

[0059] A support member 78 is connected between the detection tube 76 and the connecting sleeve 71, and the support member 78 is used to support the position of the detection tube 76;

[0060] The support member 78 includes two second connection ears 781 fixedly mounted on the outside of the connection sleeve 71, and a support rod 782 is fixedly mounted on one side of the two second connection ears 781 close to the detection tube 76, and a support block 783 is slidably sleeved on the outside of the support rod 782, and the support block 783 is fixedly connected to the detection tube 76, and a support spring 784 is fixedly connected between the support block 783 and the second connection ears 781 and between the support block 783 and the limit block 786, and the support spring 784 is sleeved on the outside of the support rod 782;

[0061] In this embodiment, when the outer insulation layer of the cable is in a convex state, it squeezes the detection tube 76 through the detection ball 77, and the detection tube 76 drives the connecting sleeve 71 to move along the Y-axis direction through the support spring 784 and the support block 783;

[0062] At the same time, in this embodiment, when the outer insulation layer of the cable is in a recessed state, the detection ball 77 is stuck in the recessed position, and the detection ball 77 drives the connecting sleeve 71 to move along the Y-axis direction through the detection tube 76, and the support spring 784 and the support block 783 at the detection tube 76.

[0063] A limit block 786 is fixedly installed on one end of the support rod 782 close to the cable, and the limit block 786 is provided to prevent the support block 783 from detaching.

[0064] The support block 783 is threadedly connected with a positioning bolt 785 that allows it to be loosely connected to the support rod 782. When the detection tube 76 is in a state of detecting the cable, the support block 783 and the support rod 782 are kept in sliding connection, that is, the positioning bolt 785 does not lock the support block 783. When the detection tube 76 is not in use for fixing, the positioning bolt 785 can be turned to lock and fix the detection tube 76.

[0065] Specific implementation process: the detection balls 77 at the multiple connection frames 43 are all moved to the outer insulation layer of the cable, and in this embodiment, the multiple detection balls 77 are arranged at close distances to ensure that the outer insulation layer of the cable is fully detected, and during the detection process, the detection balls 77 rotate relative to the outer side of the cable as the cable is released, that is, in the present invention, rolling detection is set to effectively reduce detection errors;

[0066] At the same time, when the outer insulation layer of the cable is damaged, the damaged position of the outer insulation layer of the cable is uneven, and the detection ball 77 at the detection tube 76 changes with the uneven position of the damaged position of the outer insulation layer of the cable. Since the cable is being laid, its uneven position is synchronously driven by the detection ball 77 to move the detection tube 76 during its relative movement. When the detection tube 76 moves, the fixed sleeve 74 is driven to move synchronously relative to the connection frame 43 through the connecting action of the support member 78 through the connecting sleeve 71. Since the two first connecting ears 72 at the connecting sleeve 71 are connected to the detection plate 733 through the connecting ears, the detection plate 733 pressurizes the pressure sensor 734, so that the signal value of the pressure sensor 734 changes, and the pressure sensor 734 sends a signal to the controller, and the controller sends an electrical signal to the buzzer 735. The buzzer 735 warns, thereby prompting the staff.

[0067] Embodiment 2

[0068] See also Figure 3 , Embodiment 2 is a further supplementary description of Embodiment 1, wherein a guide block 761 is provided inside the detection tube 76 and close to one end of the detection ball 77, and a through hole is provided on the guide block 761 to connect it with the spherical groove. In this embodiment, the guide block 761 is hollow inside and close to the spherical groove, and is in a hollow cone shape. This arrangement can play a role in connecting the connecting wire 8;

[0069] The detection ball 77 is made of electromagnet material, and a connecting wire 8 is installed on the detection ball 77. Figure 7 , a retractable sleeve is sleeved on the outside of the connecting wire 8, and the redundant connecting wire 8 is stored through the retractable sleeve, so that the connecting wire 8 can move with the movement of the moving frame 61, and the connecting wire 8 passes through the detection tube 76, the first retractable tube 75 and the fixed sleeve 74, and a receiving device 9 for receiving its magnetic signal is connected between the multiple connecting wires 8, and the receiving device 9 is installed on the bottom plate 1. The receiving device 9 is an existing receiving device 9 (such as a magnetic sensor) to receive the magnetic field signal around the cable. After amplification, filtering and other processing, these signals will be sent to the analysis equipment for further analysis. By analyzing the changing characteristics of the magnetic field signal (such as amplitude, phase, frequency, etc.), the location, degree and type of cable damage can be determined;

[0070] During detection, the multiple detection balls 77 may not come into contact with the outer surface of the cable. At this time, since the detection balls 77 are made of electromagnet material, when they are energized, they surround the outside of the cable for detection. When the inside of the cable or its surface is damaged, the receiving device 9 receives a signal, thereby determining the damage inside and outside the cable.
