[0034] Example

[0035] This embodiment provides a cable conveying device, such as Figure 1 As shown, it includes a column 1 and a cantilever 2. The cantilever 2 is fixed to the column 1 and is provided with a conveying mechanism. The conveying mechanism includes a first bearing assembly 31 for carrying the cable and a first drive assembly 32. The first bearing assembly 31 is provided on the cantilever 2 and includes a first conveying shaft 311. The output shaft of the first drive assembly 32 is connected to the first conveying shaft 311.

[0036] This cable conveyor is installed on the shore, with the boom 2 aligned with a docked vessel. The cable extends directly from the adapter box 9 to the first bearing assembly 31 and overlaps the upper portion of the first conveyor shaft 311. The first drive assembly 32 rotates the first conveyor shaft 311, extending the cable outward and conveying it toward the vessel. This cable conveyor eliminates the need for a reel, resulting in a simple structure, cost savings, and a small footprint, making it suitable for short-distance shore power cable transmission.

[0037] See also Figures 1 to 5 The conveying mechanism also includes a moving mechanism 33, which is arranged on the cantilever 2 and can move back and forth along the extension direction of the cantilever 2. The first bearing component 31 is connected to the moving mechanism 33 and can move back and forth along the cantilever 2 with the moving mechanism 33.

[0038] See also Figure 4 Horizontal guide rails 21 are provided on both sides of the cantilever 2 in the thickness direction. For example, the cantilever 2 is an I-beam with an I-shaped cross-section, and the web at its bottom serves as the horizontal guide rail 21. The moving mechanism 33 includes a second driver 331, a driving rolling assembly, a driven rolling assembly, and two first side plates 334. The driving rolling assembly is connected to the driving end of the second driver 331 and is driven to rotate thereby. The driven rolling assembly is connected to the driving rolling assembly and is rollably mounted on the horizontal guide rail 21.

[0039] See also Figure 4 and Figure 5 The second driver 331 is a reduction motor. Two first side plates 334 are positioned opposite each other, with one of the first side plates 334 fixed to the second driver 331. Two movable shafts 335 extend through and connect the two first side plates 334. Two connecting plates 336 are mounted symmetrically on the movable shafts 335 between the two first side plates 334. The connecting plates 336 are L-shaped and symmetrically arranged. The active rolling assembly includes a transmission wheel (not shown) and two active wheels 332. The driven rolling assembly includes two driven wheels 333. The transmission wheel is a gear 62, which is mounted on the output shaft of the second driver 331.

[0040] The structures of the driving wheel 332 and the driven wheel 333 are the same as those of the first side plate 334 and are symmetrically arranged. The driving wheel 332 includes a meshing portion and a rolling portion. Both the meshing portion and the rolling portion are cylindrical, and the rolling portion has a smaller diameter than the meshing portion. A connecting shaft is provided on the first side plate 334 at both ends of the output shaft of the second driver 331. The meshing portion is rotatably provided on the connecting shaft, and the rolling portion is located on the side of the meshing portion away from the first side plate 334. The meshing portion is circumferentially provided with teeth that mesh with the teeth of the transmission wheel. The rotation of the transmission wheel drives the two driving wheels 332 to rotate in the same direction. The circumferential outer wall surfaces of the rolling portions of the driving wheel 332 and the driven wheel 333 are both clamped on the top surface of the horizontal guide rail 21, and the end faces of the meshing portions abut against the vertical surface of the horizontal guide rail 21, so that the driving wheel 332 and the driven wheel are stably clamped on the horizontal guide rail 21, ensuring the stable operation of the moving mechanism 33. Figure 4 A limit block 22 is provided on the horizontal guide rail 21 at the front end of the cantilever 2 to prevent the moving mechanism 33 from sliding out of the cantilever 2.

[0041] The first supporting assembly 31 includes a top plate 312, two second side plates 313, and a plurality of first conveying shafts 311. The top plate 312 is fixed to the bottom surfaces of the two connecting plates 336, and the two second side plates 313 are arranged opposite to each other at the bottom of the top plate 312. The upper portion of the second side plates 313 is a vertical portion fixed to the top plate 312, and the lower portion of the second side plates 313 is an arc-shaped supporting portion. The plurality of first conveying shafts 311 are evenly spaced along the circumference of the supporting portion. The first conveying shaft 311 is provided with a plurality of rollers, and the cables are connected to the rollers. The upper portion of the vertical portion of the second side plate 313 is also provided with a first conveying shaft 311, which is provided with rollers to facilitate the auxiliary transmission of cables. Figure 2 and Figure 3 The first drive assembly 32 includes four reduction motors mounted on the second side plate 313. The output shafts of two reduction motors are connected to the topmost first conveying shaft 311, while the output shafts of the other two reduction motors are connected to the outermost first output shafts. These reduction motors drive the two first output shafts to rotate, conveying the cables downward. The reduction motors have a self-locking function to prevent damage to the cables caused by excessive pulling.

[0042] The cable conveying device also includes a transfer box 9, a second bearing assembly 4, a base 5, a third drive mechanism, a support plate 7 and a limiting mechanism 8. The end of the cantilever 2 away from the column 1 is the front end, and the end close to the column 1 is the rear end. The second bearing assembly 4 is arranged on the bottom surface of the rear end of the cantilever 2, and the first bearing assembly 31 is movably arranged at the front end of the second bearing assembly 4. The structure of the second bearing assembly 4 is similar to that of the first bearing assembly 31. The only difference is that the first conveying shaft 311 is not provided on the upper part of the vertical portion of the second side plate 313 of the second bearing assembly 4. The structures of the two can also be the same. The transfer box 9 is arranged on one side of the column 1. After the cable is led out of the transfer box 9, it extends upward and overlaps the first conveying shaft 311 of the second bearing assembly 4, and then overlaps the first conveying shaft 311 of the first bearing assembly 31. The excess cable hangs down in a U shape between the two bearing assemblies. The provision of two bearing assemblies can store shorter lengths of cable between the two, preventing the cable from directly contacting the ground and causing friction and wear.

[0043] See also Figure 6 and Figure 7 The support plate 7 is provided on the bottom surface of the column 1. The column 1 and the support plate 7 are reciprocally movable on the base 5 in a direction perpendicular to the extension direction of the cantilever 2 (i.e., the length direction of the base 5). The base 5 includes a bottom plate 52 and two third side plates 53. The third side plates 53 include two horizontal portions and a vertical portion connecting the two horizontal portions. The horizontal portion of the lower portion of the third side plates 53 is fixed to the bottom plate 52. The bottom surface of the horizontal portion of the upper portion of each third side plate 53 and the top surface of the bottom plate 52 are provided with a first guide rail 51. The support plate 7 is provided with a first slider 71 that cooperates with the upper and lower first guide rails 51. When the support seat drives the column 1 to move along the length direction of the base 5, both sides and the upper and lower parts of the support seat slide along the first guide rails 51, and the operation is stable.

[0044] The third drive mechanism includes a third driver 61 and a transmission assembly, which includes a gear 62 and a rack 63. The third drive mechanism is a motor, mounted on the support plate 7 and connected to the column 1. The driving end of the third drive mechanism extends downward from the support plate 7. The rack 63 is mounted on the top of the base plate 52 and extends along the length of the base plate 52. The gear 62 is mounted at the driving end of the third drive mechanism and meshes with the rack 63. Activating the third driver 61 drives the support plate 7, which in turn causes the column 1 to move along the length of the base plate 52.

[0045] Limiting mechanism 8 is an electric push rod, which is installed on support plate 7 with its driving end facing downward. The cable conveyor is located on the shore. When there is a positional deviation between the docked vessel and boom 2, the third driving mechanism is activated, causing support plate 7 to move column 1, aligning boom 2 with the vessel. After column 1 is moved into position, the driving end of the electric push rod extends downward to abut against the upper surface of base plate 52, positioning column 1 and preventing it from moving during use.

[0046] During operation, the cable conveying device is placed on the shore, and the cable extends upward from the adapter box 9 and is sequentially overlapped on the second bearing assembly 4 and the first bearing assembly 31. The third driver 61 is started to make the support plate 7 drive the column 1 to move along the length direction of the bottom plate 52 so that the cantilever 2 is aligned with the ship; the second driver 331 is started to make the moving mechanism 33 drive the first bearing assembly 31 to move forward or backward along the cantilever 2, so that the cable connector extending from the first bearing assembly 31 is aligned with the operator under the ship, making it convenient for the operator to grab the cable connector; the reduction motors on both sides of the second side plate 313 are started to rotate the first conveying shaft 311 to convey the cable downward.

[0047] As a first alternative implementation of Example 1, the limiting mechanism 8 can also be of other structural forms, such as providing a plurality of mounting holes in a row on the base plate 52, and inserting limit pins into the mounting holes on both sides of the support plate 7 to limit the movement of the support plate 7 after the support plate 7 is moved into position.

[0048] As a second alternative implementation of Example 1, the transmission assembly can also be driven by a transmission belt. A third driver 61 is provided at each end in the length direction of the base plate 52. Transmission wheels are provided on the driving ends of the third driver 61 respectively. A transmission belt is provided on the two transmission wheels. A second slider is provided on the transmission belt. The second slider is fixed on the support plate 7. When the third driver 61 is started, the transmission belt rotates to cause the second slider to drive the support plate 7 to move horizontally. Alternatively, the third driver 61 can be a hydraulic cylinder, which is arranged along the length direction of the base plate 52 and has its driving end facing and connected to the support plate 7. The output shaft of the hydraulic cylinder can be extended or retracted to drive the support plate 7 to move.

[0049] As a third alternative implementation of Example 1, the cantilever 2 can be movably arranged on the column 1 up and down, for example, the column 1 can be a telescopic arm, and the cantilever 2 is arranged on the top of the telescopic arm, and the height of the cantilever 2 is adjusted by the extension and retraction of the telescopic arm to adapt to the height of different docked ships; or the end of the cantilever 2 can be slidably connected to the column 1 through a ring, and a screw rod is provided on the side of the column 1, and a third slider is provided on the screw rod, and the third slider is fixedly connected to the ring, and the rotation of the screw rod drives the third slider and the ring to move up and down to adjust the height of the cantilever 2.

[0050] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
