[0036] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0038] Reference Figures 1 to 5 As shown, a pure electric tugboat cable conveying device includes a column 1, a cross arm 2, a slewing unit 3, and a cable feeding unit 4.

[0039] Column 1 extends vertically;

[0040] The rotating unit 3 is connected to the column 1 and drives the column 1 to rotate. The rotation axis of the column 1 is parallel to the vertical direction.

[0041] The horizontal arm 2 is fixed to the top of the column 1 and extends horizontally.

[0042] The cable feeding unit 4 is mounted on the cross arm 2, and the cable feeding unit 4 moves the charging cable along the extension direction of the cross arm 2.

[0043] The cable feeding unit 4 on the cross arm 2 can assist in the movement of the cable. The crew only needs to pull the cable, and the cable can move forward automatically without manual handling. Furthermore, the column 1 can rotate under the drive of the slewing unit 3, thereby adjusting the direction of cable delivery. This allows the direction of cable movement to be adjusted according to the location of the charging pile, making it more convenient.

[0044] In this embodiment, the cable feeding unit 4 includes a bracket 41, a first rotating shaft 42, a second rotating shaft 43, and a drive assembly 44. The first rotating shaft 42 and the second rotating shaft 43 are arranged parallel to each other vertically. Both the first rotating shaft 42 and the second rotating shaft 43 are rotatably mounted on the bracket 41. The first rotating shaft 42 is provided with a first rotating wheel 45, and the second rotating shaft 43 is provided with a second rotating wheel 46 corresponding to the first rotating wheel 45. The outer peripheral wall of the first rotating wheel 45 is provided with a first annular groove 451, and the outer peripheral wall of the second rotating wheel 46 is provided with a second annular groove 461. The first annular groove 451 and the second annular groove 461 are used to clamp the cable. The drive assembly 44 is connected to the first rotating shaft 42 to drive the first rotating shaft 42 to rotate.

[0045] A first rotating wheel 45 and a second rotating wheel 46 are provided. The first annular groove 451 on the first rotating wheel 45 and the second annular groove 461 on the second rotating wheel 46 will form a limiting space. The cable can pass through this limiting space and contact the first rotating wheel 45 and the second rotating wheel 46. Then, under the drive of the drive component 44, the first rotating wheel 45 will rotate, thereby driving the cable to move. The second rotating wheel 46 assists in the movement, so that the cable can move more smoothly.

[0046] In this embodiment, there are two drive components 44, which are detachably connected to both ends of the first rotating shaft 42. The first rotating shaft 42 is equipped with two drive components 44. During normal use, the two drive components 44 drive the first rotating shaft 42 to rotate together. If one of the drive components 44 is damaged, the damaged drive component 44 can be removed, and the other drive component 44 can continue to drive the first rotating shaft 42 to rotate, so that the cable feeding operation can be carried out continuously.

[0047] In this embodiment, the bracket 41 includes a first frame 411 and a second frame 412 spaced apart vertically. The first frame 411 and the second frame 412 are connected by a locking mechanism 413, and the height of the second frame 412 is adjustable.

[0048] The first rotating shaft 42 and the drive assembly 44 are both mounted on the first frame 411, and the second rotating shaft 43 is mounted on the second frame 412;

[0049] Since the height of the second frame 412 is adjustable, the distance between the first roller 45 and the second roller 46 can be adjusted to ensure that the first roller 45 and the second roller 46 can clamp the cable, and can also be adjusted adaptively according to the diameter of the cable.

[0050] In this embodiment, the locking mechanism 413 includes a bolt 4131 passing through the first frame 411 and the second frame 412. The bolt 4131 is arranged vertically, and a first nut 4132, a second nut 4133 and a third nut 4134 are sequentially threaded onto the bolt 4131. The first nut 4132 cooperates with the head of the bolt 4131 to clamp the first frame 411, and the second nut 4133 and the third nut 4134 cooperate to clamp the second frame 412.

[0051] During installation, bolts 4131 are inserted into the first frame 411 from top to bottom, with the head of bolt 4131 positioned above the first frame 411. Then, the first nut 4132 is threaded onto the first frame 411, pressing it tightly. At this point, bolt 4131 is fixed to the first frame 411. Then, the second nut 4133, the second frame 412, and the third nut 4134 are installed in sequence. The second nut 4133 and the third nut 4134 work together to fix the second frame 412. To adjust the height of the second frame 412, simply rotate the second nut 4133 and the third nut 4134 to adjust their height.

[0052] In this embodiment, circular baffles 47 are fixed on both sides of the first rotating wheel 45. The radius of the circular baffles 47 is larger than the radius of the first rotating wheel 45, and the difference between the radius of the circular baffles 47 and the radius of the first rotating wheel 45 is greater than the distance between the first rotating wheel 45 and the second rotating wheel 46. This allows the two circular baffles 47 to cooperate in blocking the cable in the limiting space and preventing the cable from coming out.

[0053] In this embodiment, the first rotating shaft 42 is provided with two first rotating wheels 45, and there are two second rotating wheels 46, which correspond one-to-one with the first rotating wheels 45, so that the two cables can be driven to move simultaneously.

[0054] In this embodiment, the first rotating shaft 42 and the drive assembly 44 are connected by a coupling. The coupling is a clamping coupling, which is clamped onto the first rotating shaft 42 by tightening screws. When disassembling, simply loosen the screws to release the coupling from the first rotating shaft 42, and the drive assembly 44 can be removed.

[0055] In this embodiment, the drive assembly 44 includes a motor and a reducer. The drive shaft of the reducer is connected to the first rotating shaft 42 via a coupling. The two motors operate synchronously through the configuration of the driver, thereby jointly driving the first rotating shaft 42 to rotate.

[0056] In this embodiment, a slide 5 is also included. The slide 5 is slidably engaged with the cross arm 2. A hydraulic cylinder 6 is provided on the cross arm 2. The hydraulic cylinder 6 is connected to the slide 5 to drive the slide 5 to move along the extension direction of the cross arm 2.

[0057] Both the cross arm 2 and the slide 5 are equipped with cable feeding units 4. The cable feeding units 4 on the cross arm 2 and the slide 5 together support the movement of the cable, making the cable movement smoother. The slide 5 can be adjusted in extension length under the drive of the hydraulic cylinder 6, which makes it convenient to adjust the position of the cable.

[0058] In practice, the cable feeding unit 4 on the cross arm 2 is located at the end of the cross arm 2 away from the carriage 5, and the cable feeding unit 4 on the carriage 5 is located at the end of the carriage 5 away from the cross arm 2.

[0059] In this embodiment, the rotary unit 3 includes a housing 31, a hollow turntable 32, a drive shaft 33, a power source 34, and a handle 35;

[0060] The hollow turntable 32 is rotatably disposed in the housing 31, and the outer peripheral wall of the hollow turntable 32 is provided with rollers;

[0061] The drive shaft 33 passes through the housing 31. A cam is provided on the drive shaft 33, and the cam is engaged with the roller drive. The drive shaft 33 is divided into a first end and a second end along its axial direction. The first end is used to connect to the power source 34, and the second end is used to connect to the handle 35.

[0062] One of the power source 34 and the handle 35 is connected to the drive shaft 33;

[0063] The cam on the drive shaft 33 engages with the rotor of the hollow turntable 32. When the drive shaft 33 rotates, the cam moves the rotor, causing the hollow turntable 32 to rotate. The first end of the drive shaft 33 can be connected to the power source 34, which drives the drive shaft 33 to rotate. If the power source 34 fails, it can be removed, and the handle 35 can be connected to the second end of the drive shaft 33. The handle 35 can be manually cranked to rotate the drive shaft 33. Through this structural design, when the power source 34 fails, the drive can be switched to the handle 35 in time, ensuring that the column 1 can rotate when needed.

[0064] The cam and roller drive structure in this embodiment is prior art, and can be found in patents 202422319086.6 and 202021439877.8. It will not be described in detail here.

[0065] In this embodiment, the outer periphery of the second end is a spline tooth structure, and the handle 35 has a spline sleeve 351, which is used to fit onto the spline tooth structure.

[0066] When using the handle 35, the spline sleeve 351 is fitted onto the spline tooth structure, and the inner wall of the spline sleeve 351 meshes with the spline tooth structure. By rotating the spline sleeve 351 through the handle 35, the drive shaft 33 is rotated.

[0067] In this embodiment, the handle 35 includes a rocker arm 352 and a handle 353; a spline sleeve 351 is fixed to one end of the rocker arm 352 along its length direction, and the length direction of the rocker arm 352 is perpendicular to the axial direction of the spline sleeve 351; the handle 353 is fixed to the other end of the rocker arm 352 away from the spline sleeve 351, and the length direction of the handle 353 is perpendicular to the length direction of the rocker arm 352.

[0068] When in use, grasp the handle 353 to shake the swing arm 352, thereby rotating the spline sleeve 351.

[0069] In this embodiment, a first flange seat 311 is fixed on the housing 31, and the drive shaft 33 passes through the first flange seat 311 to expose the second end.

[0070] It also includes a cover 36. When the drive shaft 33 is connected to the power source 34, it means that the handle 35 is not connected to the drive shaft 33. At this time, the cover 36 is detachably connected to the first flange seat 311 and covers the second end, which can protect the spline tooth structure. When it is necessary to connect the handle 35 to the drive shaft 33, the cover 36 is removed. The cover 36 can be installed on the first flange seat 311 by screws, clips or Velcro.

[0071] In this embodiment, a connecting hole is provided on the end face of the first end, a second flange seat 312 is fixed on the housing 31, the power source 34 is installed on the second flange seat 312 by locking screws, the output shaft of the power source 34 passes through the connecting hole, a key is installed on the output shaft of the power source 34, the connecting hole has a keyway, and the transmission shaft 33 is connected to the output shaft of the power source 34 by key transmission. Therefore, the power source 34 can drive the transmission shaft 33 to rotate.

[0072] The second flange seat 312 is provided with a threaded hole, which passes through the second flange seat 312 along the axial direction of the drive shaft 33. A push-out screw 313 is threadedly connected in the threaded hole. The push-out screw 313 passes through the threaded hole from the side of the second flange seat 312 away from the power source 34. The length of the push-out screw 313 is greater than the depth of the threaded hole.

[0073] When the power source 34 malfunctions, it needs to be disassembled. However, the connection between the drive shaft 33 and the output shaft of the power source 34 is quite tight, making it sometimes difficult to pull out the power source 34. Therefore, an ejector screw 313 is provided. By rotating the ejector screw 313, it can pass through the threaded hole and contact the power source 34, thereby pushing the power source 34 to separate from the second flange seat 312 and assisting in the disassembly of the power source 34. When it is not necessary to disassemble the power source 34, the ejector screw 313 will not pass through the threaded hole, thus not affecting the use of the power source 34.

[0074] In this embodiment, the axial direction of the hollow turntable 32 is vertical, which facilitates the arrangement and connection of the column 1. There are two threaded holes, which are respectively located on the upper and lower parts of the first flange seat 311. This allows for the installation of two ejector screws 313 to symmetrically eject the power source 34, preventing the output shaft of the power source 34 from getting stuck in the connection hole. Generally, a base is provided on the tugboat deck, the housing 31 is connected to the base, and the column 1 is connected to the hollow turntable 32.

[0075] In this embodiment, the power source 34 is a hydraulic motor.

[0076] In some other embodiments, the power source 34 may also be an electric motor.

[0077] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
