Description

Technical Field

[0001] This utility model relates to the technical field of cable fixing devices, and in particular to a cable fixing device for port barges. Background Technology

[0002] A barge is a vessel without a power unit that relies on other vessels for towing or pushing to navigate. It is mainly used for port transportation. The cable rigging device used on port barges is a safety device used to fix the barge's position when it is docked in port, preventing it from shifting due to factors such as water flow and wind.

[0003] However, most of the existing cable fixing devices for port barges on the market are not strong enough to prevent the cable from being pulled in the opposite direction by a sudden external force when tightening and winding the cable, resulting in poor fixing ability. In addition, most of the existing cable fixing devices for port barges on the market are not convenient for workers to adjust the tension on the cable, which may lead to excessive tension and shorten the service life of the cable.

[0004] Therefore, those skilled in the art have provided a cable fixing device for port barges to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cable fixing device for port barges. The device utilizes a reset spring in the drive mechanism to engage with the stationary chuck, allowing the moving chuck to connect with the stationary chuck. This, along with a moving roller and two fixed rollers, disperses opposing tensions, limiting the clockwise rotation of the winding roller. Furthermore, the second turntable in the adjustment mechanism drives a second threaded rod, causing the moving block to move the moving roller up and down along the moving groove, facilitating the adjustment of the cable tension.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A cable fixing device for port barges includes a fixing base, a drive mechanism, and an adjustment mechanism. The drive mechanism is installed inside the fixing base. The drive mechanism includes a winding roller and two first threaded rods. Both sides of the winding roller pass through the fixing base and are fixedly connected to a stationary chuck. A driven gear is fixedly connected to the other side of the outer wall of the winding roller. Slide grooves are opened at the upper ends of both sides inside the fixing base. A return spring is fixedly connected to the side of the slide groove away from the center of the fixing base. A movable chuck is fixedly connected to the side of the return spring near the center of the fixing base. The first threaded rod is fixedly connected to a first turntable on the side away from the center of the fixed seat. A rotating groove is opened at the lower end of the other side of the fixed seat. A servo motor is provided on the inner wall of the other side of the rotating groove. The output shaft of the servo motor is fixedly connected to a drive gear. Support frames are fixedly connected to both sides of the upper front end of the fixed seat. An adjustment mechanism is provided at the upper end of the fixed seat. The adjustment mechanism includes two second threaded rods, a moving roller, and two fixed rollers. Through the above technical solution, the reset spring inside the slide groove in the drive mechanism acts on the moving chuck, so that the moving chuck and the stationary chuck are engaged and connected. The teeth on the moving chuck and the stationary chuck are set in opposite directions, so that the winding roller can rotate counterclockwise to wind, and the clockwise rotation of the winding roller is restricted. In conjunction with winding the cable on the moving roller and the two fixed rollers, the reverse tension is dispersed, which enhances the ability to stop the reverse movement of the cable.

[0007] Furthermore, each of the support frames has a movable groove on one side near the center of the fixed seat, and each of the outer walls of the second threaded rod is threaded with a movable block. The upper end of each of the second threaded rods passes through the support frame and is fixedly connected to a second turntable. Each of the movable blocks is rotatably connected to a movable roller on one side near the center of the fixed seat, and both sides of the fixed roller are rotatably connected to the support frame. Through the above technical solution, the second turntable in the adjustment mechanism drives the second threaded rod to rotate inside the moving groove. The moving block is threadedly connected to the second threaded rod, so that the moving block can drive the moving roller connected to it to move up and down along the moving groove. In conjunction with the fixed roller connected to the support frame, the tension of the cable can be changed, making it convenient for the staff to adjust the tension of the cable.

[0008] Furthermore, a storage battery is installed in the cavity at the rear end of the fixed base, a PLC control panel is fixedly connected to the upper end of the other side of the outer wall at the rear end of the fixed base, and mounting blocks are fixedly connected to the front and rear ends of the outer walls on both sides of the fixed base. The above technical solution provides power to the device through a battery installed inside the mounting base, ensuring its normal operation. The PLC control panel fixedly connected to the mounting base allows operators to control the device's operation. The four mounting blocks fixedly connected to the mounting base, along with bolts and nuts, can fix the device in the required position, preventing overall displacement.

[0009] Furthermore, all the movable chucks slide inside the slide groove, and the side of the movable chuck near the center of the fixed seat is engaged with the stationary chuck. By setting the teeth on the moving chuck and the stationary chuck to opposite directions, when the stationary chuck rotates counterclockwise, the moving chuck can be pushed to slide along the slide groove. Under the action of the return spring, the moving chuck can return to its original position and fit and engage with the stationary chuck, thus locking the stationary chuck and preventing it from rotating clockwise.

[0010] Furthermore, the first threaded rod passes through the fixed seat and is slidably connected to the movable chuck on one side near the center of the fixed seat, and the middle part of the outer wall of the first threaded rod is threadedly connected to the fixed seat. Through the above technical solution, by threading the first threaded rod to the fixed seat and sliding it to the movable chuck, the movable chuck can slide normally along the slide groove under the push of the counterclockwise rotating stationary chuck. When the first threaded rod is rotated and extended out of the fixed seat by the first turntable, it can move the movable chuck in the slide groove, release the jamming state of the stationary chuck, and allow the winding roller to rotate clockwise to release the cable.

[0011] Furthermore, the rotating groove and the sliding groove are connected in a continuous manner, one side of the driving gear is rotatably connected to the rotating groove, and the driving gear is meshed with the driven gear; Through the above technical solution, by connecting the rotating groove and the sliding groove, the driving gear and the driven gear can mesh together. Thus, when the servo motor drives the driving gear to rotate in the rotating groove, the driven gear can drive the winding roller to rotate.

[0012] Furthermore, the bottom surface inside the moving groove is rotatably connected to the second threaded rod, and the moving blocks slide inside the moving groove; Through the above technical solution, the second turntable drives the second threaded rod to rotate inside the moving groove, so that the moving block threadedly connected to the second threaded rod can drive the moving roller to move up and down along the moving groove, changing the distance between the moving roller and the fixed roller.

[0013] Furthermore, corrugated plates are fixedly connected to both the upper and lower ends of the movable block, and the side of the corrugated plates away from the center of the movable block is fixedly connected to the movable groove. By using the above technical solution, the corrugated plate fixedly connected to the upper and lower ends of the moving block is fixedly connected to the moving groove, so that the second threaded rod inside the moving groove can be protected inside, preventing large-volume foreign objects from entering the moving groove and interfering with the rotation of the second threaded rod.

[0014] This utility model has the following beneficial effects: 1. This utility model proposes a cable fixing device for port barges. The return spring inside the slide groove in the drive mechanism acts on the moving chuck, so that the moving chuck and the stationary chuck are engaged. The teeth on the moving chuck and the stationary chuck are set in opposite directions, so that the winding roller can rotate counterclockwise to wind the cable, while restricting the clockwise rotation of the winding roller. In conjunction with winding the cable around the moving roller and two fixed rollers, the reverse tension is dispersed, thereby enhancing the ability to prevent the cable from suddenly being pulled in the opposite direction by external force and improving the fixing ability.

[0015] 2. The present invention proposes a cable fixing device for port barges. The second turntable in the adjusting mechanism drives the second threaded rod to rotate inside the moving groove. The moving block is threadedly connected to the second threaded rod, so that the moving block can drive the moving roller connected to it to move up and down along the moving groove. In conjunction with the fixed roller rotatably connected on the support frame, the tension of the cable can be changed, which makes it easier for the staff to adjust the tension on the cable and avoid excessive tension that shortens the service life of the cable.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The present invention provides a specific embodiment of a cable fixing device for port barges, comprising a fixing base 1, a driving mechanism 5 and an adjusting mechanism 7. The driving mechanism 5 is provided inside the fixing base 1. The driving mechanism 5 includes a winding roller 501 and two first threaded rods 510. Both sides of the winding roller 501 pass through the fixing base 1 and are fixedly connected to a stationary chuck 503. The other side of the outer wall of the winding roller 501 is fixedly connected to a driven gear 505. The upper ends of both sides inside the fixing base 1 are provided with sliding grooves 502. The side of the sliding groove 502 away from the center of the fixing base 1 is fixedly connected to a return spring 509. The side of the return spring 509 close to the center of the fixing base 1 is fixedly connected to a moving chuck 504. The first threaded rod 510 is fixedly connected to the first turntable 511 on the side away from the center of the fixed base 1. The lower end of the other side of the fixed base 1 is provided with a rotating groove 506. The inner wall of the other side of the rotating groove 506 is provided with a servo motor 507. The output shaft of the servo motor 507 is fixedly connected to the drive gear 508. The two sides of the upper front end of the fixed base 1 are fixedly connected with support frames 6. The upper end of the fixed base 1 is provided with an adjustment mechanism 7. The adjustment mechanism 7 includes two second threaded rods 702, a moving roller 705 and two fixed rollers 706.

[0020] A battery 2 is installed in the cavity at the rear end of the fixed base 1. A PLC control panel 3 is fixedly connected to the upper end of the other side of the outer wall at the rear end of the fixed base 1. Mounting blocks 4 are fixedly connected to the front and rear ends of the outer walls on both sides of the fixed base 1. The battery 2 installed inside the fixed base 1 can provide power to the device and ensure its normal operation. The PLC control panel 3 fixedly connected to the fixed base 1 allows the operator to control the operating status of the device. The four mounting blocks 4 fixedly connected to the fixed base 1, with the help of bolts and nuts, can fix the device in the required position to prevent damage. With the overall displacement adjusted, the movable chuck 504 slides inside the slide groove 502. The side of the movable chuck 504 closest to the center of the fixed base 1 is engaged with the stationary chuck 503. By setting the teeth on the movable chuck 504 and the stationary chuck 503 to opposite directions, when the stationary chuck 503 rotates counterclockwise, the movable chuck 504 can be pushed to slide along the slide groove 502. Under the action of the return spring 509, the movable chuck 504 can return to its original position and engage with the stationary chuck 503, preventing the stationary chuck 503 from rotating clockwise. The first threaded rod 510... One side of the first threaded rod 510, near the center of the fixed base 1, passes through the fixed base 1 and is slidably connected to the movable chuck 504. The middle part of the outer wall of the first threaded rod 510 is threadedly connected to the fixed base 1. By making the first threaded rod 510 threadedly connected to the fixed base 1 and slidably connected to the movable chuck 504, the movable chuck 504 can slide normally along the slide groove 502 under the push of the counterclockwise rotating stationary chuck 503. When the first threaded rod 510 is rotated and extended out of the fixed base 1 by the first turntable 511, it can move the movable chuck 504 in the slide groove 502, releasing the stationary chuck. The engagement state of 503 allows the winding roller 501 to rotate clockwise, releasing the cable. The rotating groove 506 and the sliding groove 502 are connected through. One side of the drive gear 508 is rotatably connected to the rotating groove 506. The drive gear 508 and the driven gear 505 are meshed together. By connecting the rotating groove 506 and the sliding groove 502 through, the drive gear 508 and the driven gear 505 can mesh together. Thus, when the servo motor 507 drives the drive gear 508 to rotate in the rotating groove 506, the driven gear 505 can drive the winding roller 501 to rotate.

[0021] Reference Figure 1 , Figure 2 and Figure 4 Each of the support frame 6 has a movable groove 701 on one side near the center of the fixed seat 1. The outer wall of the second threaded rod 702 is threaded with a movable block 703. The upper end of the second threaded rod 702 passes through the support frame 6 and is fixedly connected to a second turntable 704. The movable block 703 is rotatably connected to the movable roller 705 on one side near the center of the fixed seat 1. Both sides of the fixed roller 706 are rotatably connected to the support frame 6.

[0022] The bottom surface inside the movable groove 701 is rotatably connected to the second threaded rod 702. The movable blocks 703 slide inside the movable groove 701. The second turntable 704 drives the second threaded rod 702 to rotate inside the movable groove 701, so that the movable blocks 703 threaded to the second threaded rod 702 can drive the movable roller 705 to move up and down along the movable groove 701, changing the distance between the movable roller 705 and the fixed roller 706. Corrugated plates 707 are fixedly connected to the upper and lower ends of the movable blocks 703. The side of the corrugated plates 707 away from the center of the movable blocks 703 is fixedly connected to the movable groove 701. By fixing the corrugated plates 707 fixedly connected to the upper and lower ends of the movable blocks 703 to the movable groove 701, the second threaded rod 702 inside the movable groove 701 can be protected inside, preventing large-volume foreign objects from entering the movable groove 701 and interfering with the rotation of the second threaded rod 702.

[0023] Working principle: When using the cable fixing device for port barges, the workers first use bolts and nuts to fix the device in the required place with the mounting block 4 fixedly connected to the fixing seat 1. The battery 2 inside the fixing seat 1 is used to power the device. Then, the cable wound on the winding roller 501 is wound on the moving roller 705 and the fixed roller 706. When the barge is moored, the cable is looped around the mooring post on the hull. Secondly, the staff starts the servo motor 507 through the PLC control panel 3 to drive the drive gear 508 to rotate. Through the driven gear 505, the winding roller 501 rotates counterclockwise. The reset spring 509 acts on the moving chuck 504, so that the moving chuck 504 is engaged with the stationary chuck 503. With the help of the moving roller 705 and the two fixed rollers 706, the reverse tension is dispersed, and the winding roller 501 is restricted from being pulled by the cable to rotate clockwise. Then, as the winding roller 501 rotates counterclockwise, the cable is tightened. Multiple devices work together to complete the mooring of the barge. Finally, the operator can drive the second threaded rod 702 to rotate via the second turntable 704, causing the moving block 703 to move up and down along the moving groove 701 with the moving roller 705, thereby changing the tightness of the cable and adjusting the tension on the cable. When it is necessary to release the cable, the operator uses the first turntable 511 to drive the first threaded rod 510 to extend out of the fixed seat 1, releasing the moving chuck 504 from the stationary chuck 503, and using the PLC control panel 3 to start the servo motor 507, causing the winding roller 501 to rotate clockwise and release the cable.
