Description

Technical Field

[0001] This utility model relates to the field of winding devices, specifically to a shore power cable winding device. Background Technology

[0002] In simple terms, a ship-to-shore power system means that when a ship is docked at a pier, it stops using its onboard auxiliary generators and instead uses land-based power to supply power to the main shipboard systems. This process requires cables to power the ship, necessitating the use of cable reeling equipment.

[0003] In the prior art, utility model patent application number CN202323255852.9 discloses a rapid winding and unwinding auxiliary device for shore power charging cables. A winding and unwinding assembly for winding or unwinding the charging cable is arranged between the left and right upright plates. A limiting guide assembly is provided on the front side of the upper end of the supporting base plate to prevent the charging cable from stacking during winding. The winding and unwinding assembly includes winding and unwinding rollers; the limiting guide assembly includes a reciprocating screw, and a reciprocating moving seat is provided on the annular side of the reciprocating screw. A limiting ring is provided on the front side of the upper end of the reciprocating moving seat. The reciprocating screw drives the reciprocating moving seat to move left and right reciprocally, so that the charging cable is guided by the limiting ring, preventing the charging cable from stacking in one place during winding and unwinding.

[0004] However, the aforementioned cable quick take-up and unwinding auxiliary device does not have a structure to press the cable tightly onto the take-up and unwinding rollers. After the cable is wound up, it is impossible to effectively fix the cable on the take-up and unwinding rollers, which can easily lead to the cable becoming loosely wrapped on the take-up and unwinding rollers. Summary of the Invention

[0005] The purpose of this invention is to provide a shore power cable winding device that uses pressure rollers to press the cable tightly onto the drum, thereby preventing the cable from loosening and solving the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A shore power cable winding device includes a base plate on which two mounting boxes are fixedly mounted opposite each other. A cable winding drum is rotatably mounted between the two mounting boxes, and the drum extends laterally. Guide rail boxes are fixedly mounted on the top of the two mounting boxes respectively. An adjusting plate is slidably mounted vertically between the two guide rail boxes. A bracket is slidably mounted vertically below the adjusting plate. A spring connects the adjusting plate and the bracket. A pressure roller for pressing the cable tightly onto the drum is rotatably mounted on the bracket. The pressure roller is parallel to the drum and located directly above the drum.

[0007] As a further improvement, baffles are fixedly installed at both ends of the drum, and the bracket and the pressure roller are located between the two baffles; mounting shafts coaxially arranged with the drum are fixedly installed on the outer sides of the two baffles, and the two mounting shafts are rotatably installed on the corresponding mounting boxes.

[0008] As a further improvement, the openings of the two guide rail boxes are arranged opposite each other. A vertically extending guide post is fixedly installed inside one of the guide rail boxes, and one end of the adjusting plate is slidably installed on the guide post. A vertically extending lead screw is rotatably installed inside the other guide rail box, and the other end of the adjusting plate is screwed onto the lead screw.

[0009] As a further improvement, a drive motor is installed in one of the mounting boxes, and the end of the mounting shaft on the corresponding side extends into the mounting box and is connected to the motor shaft of the drive motor; the lower end of the lead screw extends into the corresponding mounting box and is fixedly installed with a large bevel gear, and the end of the mounting shaft on the corresponding side extends into the mounting box and is fixedly installed with a small bevel gear that meshes with the large bevel gear.

[0010] As a further improvement, a sliding column parallel to the drum is fixedly installed between the two mounting boxes. A slide block is slidably installed on the sliding column, and a guide sleeve for the cable to pass through is fixedly installed on the slide block. The guide sleeve extends radially along the drum. A power mechanism for driving the slide block to reciprocate along the length of the drum is also provided between the two mounting boxes.

[0011] As a further improvement, the power mechanism includes a reciprocating lead screw rotatably mounted between the two mounting boxes, the reciprocating lead screw being arranged parallel to the sliding column, and a lead screw nut matching the reciprocating lead screw being fixedly mounted on the slide block; one end of the reciprocating lead screw is connected to one of the mounting shafts for transmission.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This application uses pressure rollers to achieve two objectives: firstly, during the cable winding process, the spring's thrust acts on the support, causing the pressure rollers to press down on the cable at the top of the drum, making the cable winding tighter; secondly, after the cable is wound up, the pressure rollers also press down on the cable at the top of the drum, thereby preventing the cable from loosening and falling off. In this application, when the drum rotates to wind up the cable, as the thickness of the cable on the drum increases, the drum drives the screw to rotate in the forward direction through the small bevel gear. In turn, the screw drives the adjusting plate to slide upward along the guide column, so that the spring's thrust on the bracket is kept within a certain range, avoiding the pressure roller's clamping force on the cable being too loose or too tight. In the process of winding cables on a drum, the active pulley drives the driven pulley and the reciprocating screw to rotate via a belt. The reciprocating screw then drives the slide and the guide sleeve to move back and forth along the length of the drum. The guide sleeve then drives the cables to be neatly arranged on the drum.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 3 As shown, a shore power cable winding device includes a base plate 1, with movable wheels 2 installed at the four corners of the bottom of the base plate 1, and a push-pull handle 3 fixedly installed at the top of the rear end of the base plate 1 to facilitate the movement of the base plate 1.

[0018] Two mounting boxes 4, arranged opposite each other, are bolted to the top of the base plate 1. A reel 5 for winding cables is rotatably mounted between the two mounting boxes 4, and the reel 5 extends laterally. Baffles 6 are welded to or bolted to both ends of the reel 5 to prevent the cable from falling off the end of the reel 5. Mounting shafts 7, coaxial with the reel 5, are welded to or bolted to the outer sides of the two baffles 6. The two mounting shafts 7 are rotatably mounted on the side walls of the corresponding mounting boxes 4 via bearings. In this embodiment, a drive motor 8 is bolted to the left mounting box 4, and the end of the left mounting shaft 7 extends into the mounting box 4 and is connected to the motor shaft of the drive motor 8 via a coupling, thereby driving the reel 5 to rotate and wind or unwind the cable via the drive motor 8.

[0019] The tops of the two mounting boxes 4 are respectively fixed with guide rail boxes 9 by bolts. An adjusting plate 10 is vertically slidably installed between the two guide rail boxes 9. Below the adjusting plate 10, an inverted U-shaped bracket 11 is vertically slidably installed. The bracket 11 has a horizontal plate and vertical plates bent downwards at the left and right ends of the horizontal plate. Two connecting columns 12 are installed on the bracket 11, which are arranged opposite each other. The connecting columns 12 extend vertically and are connected to the bracket 11 by threads. The connecting columns 12 are vertically slidably installed on the adjusting plate 10. The upper end of the connecting column 12 is also integrally formed with a stop block 13 to prevent the bracket 11 from falling off the bottom of the adjusting plate 10. A spring 14 is sleeved on the connecting column 12 located between the adjusting plate 10 and the bracket 11. A pressure roller 15 for pressing the cable tightly onto the drum 5 is rotatably installed between the two vertical plates of the bracket 11. The pressure roller 15 is arranged parallel to the drum 5 and is located directly above the drum 5. The bracket 11 and the pressure roller 15 are both located between two baffles 6.

[0020] By setting the pressure roller 15, firstly, during the process of the drum 5 winding the cable, the thrust of the spring 14 acts on the bracket 11, thereby causing the pressure roller 15 to press down on the cable located at the top of the drum 5, making the cable winding more tightly; secondly, after the cable is wound up, the pressure roller 15 also presses down on the cable located at the top of the drum 5, thereby preventing the cable from loosening and falling off.

[0021] The openings of the two guide rail boxes 9 are arranged opposite each other. A vertically extending guide post 16 is fixedly installed in the left guide rail box 9 by bolts. The left end of the adjusting plate 10 is slidably installed on the guide post 16, so that the adjusting plate 10 can move up and down above and below the drum 5. A vertically extending lead screw 17 is rotatably installed in the right guide rail box 9 by bearings. The right end of the adjusting plate 10 is screwed onto the lead screw 17. By rotating the lead screw 17, the adjusting plate 10 can be driven to slide up and down along the guide post 16, thereby changing the compression degree of the spring 14, and thus adjusting the thrust of the spring 14 on the bracket 11.

[0022] The lower end of the lead screw 17 extends into the mounting box 4 on the right and is fixedly mounted with a large bevel gear 18. The end of the mounting shaft 7 on the right extends into the mounting box 4 and is fixedly mounted with a small bevel gear 19 that meshes with the large bevel gear 18. Thus, during the rotation of the drum 5, the lead screw 17 can be driven to rotate through the small bevel gear 19. Specifically, when the drive motor 8 drives the drum 5 to rotate forward to wind the cable, as the thickness of the cable on the drum 5 increases, the pressure roller 15 and the bracket 11 are raised accordingly. At the same time, the drum 5 drives the lead screw 17 to rotate forward through the small bevel gear 19, and then the lead screw 17 drives the adjusting plate 10 to slide upward along the guide post 16, so that the thrust of the spring 14 on the bracket 11 is kept within a certain range, avoiding the pressure of the pressure roller 15 on the cable being too loose or too tight.

[0023] A sliding column 20, parallel to the drum 5, is fixedly installed between the two mounting boxes 4 by bolts. A slide block 21 is slidably installed on the sliding column 20. A guide sleeve 22 for the cable to pass through is welded to the top of the slide block 21. The guide sleeve 22 is located in front of the drum 5 and extends radially along the drum 5. A power mechanism for driving the slide block 21 to reciprocate along the length of the drum 5 is also provided between the two mounting boxes 4.

[0024] The power mechanism includes a reciprocating lead screw 23 rotatably mounted between two mounting boxes 4 via bearings. The reciprocating lead screw 23 is arranged parallel to the sliding column 20. A lead screw nut 24 matching the reciprocating lead screw 23 is fixedly mounted on the slide block 21 by bolts. The left end of the reciprocating lead screw 23 extends into the mounting box 4 on the left and is fixedly mounted with a driven pulley 25. A driving pulley 26 is fixedly mounted on the mounting shaft 7 on the left. A belt 27 connects the driving pulley 26 and the driven pulley 25.

[0025] During the process of the drive motor 8 driving the drum 5 to wind up the cable, the drive pulley 26 drives the driven pulley 25 and the reciprocating screw 23 to rotate through the belt 27. In turn, the reciprocating screw 23 drives the slide 21 and the guide sleeve 22 to move back and forth along the length of the drum 5. The guide sleeve 22 drives the cable to be neatly arranged on the drum 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
