Shore connection cable reel for ship

Abstract

The invention belongs to the technical field of ship electricity and shore power, and discloses a shore connection cable reel for a ship. The shore connection cable reel for the ship comprises a rack, a winding piece, a driving piece, a cable arranging device and a transmission assembly. The input end of the transmission assembly is in transmission connection with the second end of the winding part, and the output end of the transmission assembly is in transmission connection with the wire arranging device to drive the wire arranging device to move left and right, so that the cable is wound on the winding part. When the cable is wound, the transmission ratio between the transmission assembly and the traverse unit is adjustable, the transmission ratio between the transmission assembly and the traverse unit can be gradually reduced along with the gradual increase of the winding radius of the cable on the winding part, the left-right moving speed of the traverse unit is reduced, and the situation that the moving speed of the winder is constant along with the increase of the winding radius is avoided. As a result, gaps are formed between every two circles of cables on the winding piece, and the cables are not tightly arranged. When the shore connection cable reel for the ship releases the cable, the transmission ratio between the transmission assembly and the cable arranging device can be gradually increased, and the cable is prevented from being wound in the releasing process.

Description

Technical Field

[0001] The present invention relates to the technical field of ship electric and shore power, and particularly relates to a shore connection cable reel for ships. Background Art

[0002] The shore connection cable reel for ships is an important device for connecting the shore power system when the ship berths. Its core function is to efficiently and safely wind and unwind high-voltage cables to ensure the power transmission between the ship and the shore power. During the process of winding the cable, due to the lack of an effective traction mechanism, the cable cannot be evenly and tightly wound on the reel, resulting in inconsistent tightness of the cable on the reel, reducing the space utilization rate of the reel and increasing the risk of the cables winding around each other.

[0003] A related technology discloses an intelligent winding and unwinding device for ship shore power cables. A bidirectional lead screw drives a moving rod to move left and right. A cable winding and unwinding port for the cable to pass through is arranged on the moving rod. When the moving rod moves left and right on the bidirectional lead screw, the cable passing through the winding and unwinding port is driven to move left and right accordingly. The cable realizes an orderly arrangement on the cable reel through the rotation of the cable reel and the left and right movement of the moving rod.

[0004] However, the bidirectional lead screw of the intelligent winding and unwinding device for ship shore power cables is driven by a motor with a constant rotation speed, so that the speed of the bidirectional lead screw driving the moving rod to move left and right is constant. As the winding radius of the cable on the cable reel increases, the length of the cable wound around the cable reel in one revolution increases. If the moving rod still moves left and right at a constant speed, gaps are generated between each turn of the cable on the cable reel, resulting in an uneven and loose arrangement of the cable on the cable reel. Summary of the Invention

[0005] The purpose of the present invention is to provide a shore connection cable reel for ships to solve the technical problem that the cable winding and unwinding device in the prior art cannot adjust the left and right moving speed of the cable according to the winding radius of the cable, resulting in an uneven and loose arrangement of the cable on the cable reel.

When the shore connection cable reel for ships releases the cable, as the winding radius of the cable on the winding component gradually decreases, the transmission ratio between the transmission component and the wire arranging device can be gradually increased to increase the speed of the left and right movement of the wire arranging device, avoiding the entanglement of the cable during the release process.

[0040] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar components or components with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0041] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium. It can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0042] In the description of the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first feature and the second feature, or may include the situation where the first feature and the second feature are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.

[0043] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific implementation manners.

[0044] As Figures 1 - 10 shown, the present invention provides a shore connection cable reel for a ship, which includes a frame 1, a winding member 2, a driving member 3, a wire arranging device 4 and a transmission assembly 5. The winding member 2 is rotatably connected to the frame 1. The driving member 3 is drivingly connected to the first end of the winding member 2, and the driving member 3 is configured to drive the winding member 2 to rotate on the frame 1. The wire arranging device 4 is arranged on the frame 1, and the wire arranging device 4 is configured to guide the cable to wind around the winding member 2. The input end of the transmission assembly 5 is drivingly connected to the second end of the winding member 2, the output end of the transmission assembly 5 is drivingly connected to the wire arranging device 4, and the transmission ratio between the transmission assembly 5 and the wire arranging device 4 is adjustable.

[0045] Specifically, the winding member 2 is horizontally connected to the frame 1. The winding member 2 can be a cylindrical drum or a hexagonal or octagonal drum, and no specific limitation is made here. As Figure 9 shown, the driving member 3 is vertically arranged on the frame 1, and the driving member 3 and the first end of the winding member 2 are drivingly connected through two bevel gears. The driving member 3 can be a motor or a pneumatic motor, and no specific limitation is made here.

[0046] The input end of the transmission assembly 5 is drivingly connected to the second end of the winding member 2, that is, the winding member 2 drives the transmission assembly 5 to operate. The output end of the transmission assembly 5 is drivingly connected to the wire arranging device 4 to drive the wire arranging device 4 to move left and right, so as to wind the cable around the winding member 2. When the shore connection cable reel for a ship winds the cable, the transmission ratio between the transmission assembly 5 and the wire arranging device 4 is adjustable. As the winding radius of the cable on the winding member 2 gradually increases, the transmission ratio between the transmission assembly 5 and the wire arranging device 4 can be gradually reduced to reduce the moving speed of the wire arranging device 4 left and right, so as to avoid that as the winding radius increases, that is, the winding length of the cable around the winding member 2 for one week increases, and the moving speed of the wire arranging device 4 left and right still remains constant, resulting in gaps between each turn of the cable on the winding member 2 and the cable arrangement not being tight enough. When the shore connection cable reel for a ship releases the cable, as the winding radius of the cable on the winding member 2 gradually decreases, the transmission ratio between the transmission assembly 5 and the wire arranging device 4 can be gradually increased to increase the moving speed of the wire arranging device 4 left and right, so as to avoid the cable from being wound during the release process.

[0047] Specifically, as Figures 1 - 4 shown, the transmission assembly 5 includes a first transmission member 51, a second transmission member 52 and a transmission shaft group 53. The first transmission member 51 is drivingly connected to the second end of the winding member 2 through a speed reducer 54 and rotates coaxially with the winding member 2. The second transmission member 52 is drivingly connected to the first transmission member 51 and rotates coaxially with the first transmission member 51. The first transmission member 51 and the second end of the winding member 2 are drivingly connected through a speed reducer 54, so that the rotation speed of the first transmission member 51 is less than the rotation speed of the winding member 2. In this embodiment, as Figure 3As shown, the reducer 54 is a planetary reducer, a reduction groove is provided at the center of the first transmission member 51, an inner gear ring is provided at the inner circle of the reduction groove, the second end of the reel 2 extends into the reduction groove and a central gear is provided, three planetary gears are rotatably connected to the outer periphery of the central gear in the reduction groove, each planetary gear is meshed with the inner gear ring and the central gear, and the free end of the central gear is connected to the second transmission member 52 via a connecting shaft. In other embodiments, the reducer 54 can also be a friction wheel reduction mechanism or other forms of gear reduction mechanisms.

[0048] like Figure 2 As shown, the transmission shaft assembly 53 includes a first sleeve 531, a second sleeve 532, a transmission shaft 533 and a driven shaft 534 which are coaxially arranged. The first sleeve 531 is fixedly connected to the frame 1, the second sleeve 532 is screwed to the first end of the first sleeve 531, the transmission shaft 533 is rotatably connected to the second sleeve 532 and cannot move along the axial direction of the second sleeve 532, and the axial movement of the transmission shaft 533 along the second sleeve 532 can be limited by setting a shoulder and an elastic retaining ring in the second sleeve 532. The driven shaft 534 is inserted into the first sleeve 531 from the second end of the first sleeve 531 and is rotatably connected to the first sleeve 531, and the driven shaft 534 cannot move along the axial direction of the first sleeve 531, so as to prevent the driven shaft 534 from falling off from the first sleeve 531. The transmission shaft 533 and the driven shaft 534 are transmission-connected and the transmission shaft 533 can move along the axial direction of the driven shaft 534. Specifically, a rectangular plug shaft is provided at one end of the transmission shaft 533 close to the driven shaft 534 , and a rectangular plug hole is provided at one end of the driven shaft 534 close to the transmission shaft 533 , and the transmission shaft 533 and the driven shaft 534 are plugged together.

[0049] like Figure 1 , Figure 3 and Figure 4 As shown, a plurality of driving grooves 521 are radially arranged on one side of the second transmission member 52, and a plurality of engaging teeth 5331 are arranged on one end of the transmission shaft 533 away from the driven shaft 534. The driving grooves 521 are matched and connected with the engaging teeth 5331, and the density of the driving grooves 521 increases from the center to the edge of the second transmission member 52. A plurality of driving teeth 511 are radially arranged on one side of the first transmission member 51, and a plurality of driving teeth 5321 are arranged on the outer periphery of the second sleeve 532. The driving teeth 511 and the driving teeth 5321 are matched and connected to drive the second sleeve 532 to move along the axial direction of the first sleeve 531, and the driven shaft 534 is drivingly connected with the cable arranging device 4.

[0050] Specifically, the second transmission member 52 drives the transmission shaft 533 to rotate through the driving groove 521 and the engaging tooth 5331 , and the transmission shaft 533 drives the driven shaft 534 to rotate. The driven shaft 534 is connected to the cable arranging device 4 through the bevel gear to drive the cable arranging device 4 to operate. Furthermore, the first transmission member 51 drives the second sleeve 532 to rotate by cooperating with the driving tooth 511 and the transmission tooth 5321. Since the second sleeve 532 and the first sleeve 531 are threadedly connected, the rotation of the second sleeve 532 enables the second sleeve 532 to move along the axial direction of the first sleeve 531, thereby driving the transmission shaft 533 to move, changing the distance between the transmission shaft 533 and the center of the second transmission member 52, and the density of the driving groove 521 increases from the center to the edge of the second transmission member 52. When the transmission shaft 533 moves away from the center of the second transmission member 52, the transmission ratio between the transmission assembly 5 and the cable arranger 4 increases, and then the speed of the cable arranger 4 moving left and right decreases. Conversely, the transmission ratio between the transmission assembly 5 and the cable arranger 4 decreases, and the speed of the cable arranger 4 moving left and right increases.

[0051] In this embodiment, the first transmission member 51 and the second transmission member 52 are both disc-shaped structures, so that the transmission connection between the first transmission member 51 and the transmission shaft 533 is more stable and the transmission relationship between the first transmission member 51 and the second sleeve 532 is more stable. In other embodiments, the first transmission member 51 and the second transmission member 52 can be replaced with a rectangular plate structure.

[0052] Furthermore, if Figure 5 As shown, the cable arranging device 4 includes two parallel threaded drive shafts 41, both of which are rotatably connected to the frame 1, and a transmission gear is provided on the same side of the two threaded drive shafts 41, and the two transmission gears are meshed, so that the two threaded drive shafts 41 always rotate in opposite directions. The cable arranging device 4 also includes a cable pulling sleeve 42, which is used to pull the cable, and the cable pulling sleeve 42 can be alternately connected to one of the two threaded drive shafts 41, thereby driving the cable to move left and right, and one of the two threaded drive shafts 41 is transmission-connected to the driven shaft 534 of the transmission assembly 5, so that the threaded drive shaft 41 can rotate.

[0053] like Figures 5 - 7As shown in the figure, a first slide rail 11 and a second slide rail 12 are also arranged at intervals on the frame 1. Two screw drive shafts 41 are located between the first slide rail 11 and the second slide rail 12. One side of the cable drag sleeve 42 is fixedly connected with a swing member 13. C-shaped screw sleeves 131 are arranged at both the upper and lower ends of the swing member 13. The C-shaped screw sleeve 131 can be engaged with the screw drive shaft 41, so that the rotation of the screw drive shaft 41 drives the cable drag sleeve 42 to move. Two mutually parallel chutes 111 extending along the length direction of the screw drive shaft 41 are opened on both the first slide rail 11 and the second slide rail 12. The two ends of the two chutes 111 are connected through an alternating slideway 112. A connecting swing bar 1311 is rotatably connected to the C-shaped screw sleeve 131, and a slide bar 1312 is rotatably connected to the connecting swing bar 1311. One of the C-shaped screw sleeves 131 is slidably connected to the chute 111 of the first slide rail 11 through the slide bar 1312. The other C-shaped screw sleeve 131 is slidably connected to the chute 111 of the second slide rail 12 through the slide bar 1312. As Figure 7 shown, a magnetic member 113 is arranged on the inner wall of each alternating slideway 112. The two magnetic members 113 on the first slide rail 11 are distributed alternately front and back. The two magnetic members 113 on the second slide rail 12 are distributed alternately front and back. And the two magnetic members 113 at the same end of the first slide rail 11 and the second slide rail 12 are distributed alternately front and back. The two slide bars 1312 are made of a material that can be magnetically attracted by the magnetic member 113.

[0054] Exemplarily, when the C-shaped screw sleeve 131 at the upper end of the swing member 13 is engaged with the screw drive shaft 41, the slide bar 1312 of the upper C-shaped screw sleeve 131 slides in the chute 111 inside the second slide rail 12. At this time, the C-shaped screw sleeve 131 at the lower end of the swing member 13 is not engaged with the screw drive shaft 41, and the slide bar 1312 of the lower C-shaped screw sleeve 131 slides in the chute 111 outside the first slide rail 11. The cable drag sleeve 42 moves to the left under the drive of the upper screw drive shaft 41. When moving to the leftmost end of the chute 111, the magnetic member 113 in the alternating slideway 112 of the first slide rail 11 attracts the slide bar 1312 on the lower C-shaped screw sleeve 131 inward, so that the lower C-shaped screw sleeve 131 is engaged with the lower screw drive shaft 41. The magnetic member 113 in the alternating slideway 112 of the second slide rail 12 attracts the slide bar 1312 on the upper C-shaped screw sleeve 131 outward, so that the upper C-shaped screw sleeve 131 is separated from the upper screw drive shaft 41. At this time, the cable drag sleeve 42 moves to the right under the drive of the lower screw drive shaft 41. The cable arranging device 4 pulls the cable to move left and right through the above principle.

[0055] Further, a connecting swing bar 1311 is rotatably connected to the C-shaped threaded sleeve 131. A sliding bar 1312 is rotatably connected to the connecting swing bar 1311. The length of the sliding bar 1312 is greater than the depth of the sliding groove 111, so that the sliding bar 1312 can slide up and down relative to the sliding groove 111 without interference with the sliding groove 111 during the forward and backward alternation of the C-shaped threaded sleeve 131 in the alternating slideway 112. And the sliding bar 1312 can rotate relative to the connecting swing bar 1311, so that the sliding bar 1312 can keep in contact with the magnetic part 113 during the forward and backward alternation of the C-shaped threaded sleeve 131.

[0056] As Figure 6 shown, the cable dragging sleeve 42 includes a frame 421 and two pulleys 422. The two pulleys 422 are rotatably arranged at intervals inside the frame 421. Specifically, the frame 421 is a rectangular frame. The outer peripheries of the pulleys 422 are recessed inward to form arcs that match the cable, so that the cable can pass through the cable dragging sleeve 42 more smoothly and prevent the cable from getting stuck in the cable dragging sleeve 42.

[0057] Optionally, as Figure 8 and Figure 9 shown, an electrical connection head 21 is arranged on the cable reel 2. One end of the cable reel 2 is also provided with a power connection rotating shaft 22. A power connection end 221 is arranged on the power connection rotating shaft 22. A slip ring 23 is rotatably connected to the power connection rotating shaft 22. The electrical connection head 21 is electrically connected to the power connection end 221, so that when the cable is wound around the cable reel 2, the power connection state can be always maintained.

[0058] Further, limiting disks 24 are arranged at both ends of the cable reel 2 to prevent the cable from falling off the cable reel 2 after being wound around the cable reel 2.

[0059] Optionally, a housing 6 can also be arranged outside the frame 1. A cable inlet and outlet 61 is opened on the housing 6. The cable enters from the cable inlet and outlet 61 and is wound around the cable reel 2 under the traction of the cable dragging sleeve 42. The housing 6 can protect the internal structure of the cable reel for ships from seawater and rain erosion and improve the service life of the shore connection cable reel for ships.

[0060] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
