Description

Technical Field

[0001] This utility model relates to the field of winch technology, specifically a winch for sand suction vessels that is easy to install. Background Technology

[0002] A dredging vessel, also known as a sand dredging platform, uses hydraulic power to pump silt (or fine sand, sea sand, etc.) uplifted by a high-pressure water jet. The dredging vessel is then transported to its destination via a pipe by a dredging pump. The winch on the dredging vessel can wind up the wire rope or the hydraulic system can adjust the depth of the suction pipe in the water to ensure precise contact with the sand layer (such as the riverbed) and avoid a decrease in suction efficiency due to changes in water level.

[0003] Existing winches for sand dredging vessels are often fixed by bolts or welding during installation. However, since the winches are generally installed on the deck of the sand dredging vessel, the nuts are prone to rusting onto the bolts after long-term exposure to wind and rain. This makes disassembly difficult when the winch malfunctions. Therefore, this utility model provides a winch for sand dredging vessels that is easy to install. Utility Model Content

Each end is slidably equipped with a trapezoidal slider. One end of the trapezoidal slider is fixedly connected to a rod. A first spring is sleeved on the surface of the rod. A screw is installed inside the mounting groove. A threaded sleeve is threadedly engaged on the surface of the screw. Fixing plates are fixedly installed on both sides of the threaded sleeve. A roller that abuts against the trapezoidal slider is fixedly installed at one end of the fixing plate. One end of the screw rotates through the mounting groove and is fixedly connected to a worm gear. A protective cover is fixedly installed on one side of the horizontal plate on the mounting base. A worm gear that meshes with the worm gear is installed inside the protective cover. One end of the worm gear rotates through the protective cover and is fixedly connected to a knob.

[0008] Preferably, a limiting frame is fixedly installed inside the mounting groove on both sides of the screw, and a second spring is fixedly installed on the limiting frame, with one end of the second spring abutting against the fixing plate.

[0009] Preferably, the upper surface of the base is provided with two fixing blocks on one side of the winding drum, and a threaded rod is installed between the two fixing blocks.

[0010] Preferably, a movable block is threadedly engaged on the surface of the threaded rod, and two guide rollers are fixedly mounted on the upper surface of the movable block.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a winch for sand suction vessels that is easy to install, and has the following beneficial effects:

[0015] This easy-to-install winch for sand dredging vessels is designed with a mounting base, base, trapezoidal slider, insert rod, first spring, screw, threaded sleeve, fixing plate, roller, worm gear, protective cover, worm, knob, limiting frame, and second spring. In use, the mounting base is fixed to the deck of the sand dredging vessel, and then the base is placed on the mounting base with the horizontal plates on both sides abutting against it. Turning the knob drives the worm gear to rotate, which in turn drives the screw to rotate. As the screw rotates, the threaded sleeve moves laterally along the limiting frame, causing the roller to press against the trapezoidal slider, causing it to move longitudinally. This then drives the insert rod to be inserted into the base for fixation, facilitating the disassembly and installation of the winch. It is suitable for various models of winch units.

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.

[0021] Please see Figure 1-3This utility model provides a technical solution: It includes a mounting base 1, a base 2 mounted on the upper surface of the mounting base 1, two support seats 3, a drive motor 4, and a reduction gearbox 5 fixedly mounted on the upper surface of the base 2. The two support seats 3 are mounted on the same rotating shaft, and a winding drum 6 is fixedly sleeved on the rotating shaft. A steel wire rope is wound around the surface of the winding drum 6. The output end of the drive motor 4 is fixedly connected to the input end of the reduction gearbox 5. The output end of the reduction gearbox 5 is fixedly connected to one end of the rotating shaft. Mounting grooves 7 are provided inside the horizontal plates on both sides of the mounting base 1. Trapezoidal sliders 8 are slidably arranged at both ends inside the mounting grooves 7. A rod 9 is fixedly connected to one end of each trapezoidal slider 8, and a first spring 10 is sleeved on the surface of the rod 9. A screw 11 is installed inside the groove 7. A threaded sleeve 12 is threaded onto the surface of the screw 11. Fixing plates 13 are fixedly installed on both sides of the threaded sleeve 12. A roller 14 that abuts against the trapezoidal slider 8 is fixedly installed at one end of the fixing plate 13. One end of the screw 11 rotates through the mounting groove 7 and is fixedly connected to a worm gear 15. A protective cover 16 is fixedly installed on one side of the horizontal plate on the mounting base 1. A worm 17 that meshes with the worm gear 15 is installed inside the protective cover 16. One end of the worm 17 rotates through the protective cover 16 and is fixedly connected to a knob 17. Limiting frames 19 are fixedly installed on both sides of the screw 11 inside the mounting groove 7. A second spring 20 is fixedly installed on the limiting frames 19. One end of the second spring 20 abuts against the fixed plate 13. Through the coordinated arrangement of the mounting base 1, base 2, trapezoidal slider 8, insert rod 9, first spring 10, screw 11, threaded sleeve 12, fixed plate 13, roller 14, worm gear, protective cover 16, worm 17, knob 18, limiting frame 19, and second spring 20, in use, the mounting base 1 is fixedly installed on the deck of the dredging vessel. Then, the base 2 is placed on the mounting base 1, with the horizontal plates on both sides abutting against it. Then, by rotating the knob 18, the worm 17 is driven to rotate. At this time, the meshing worm gear 15 drives the screw 11 to rotate. Because the screw 11 rotates, the threaded sleeve 12 moves laterally along the limiting frame 19, thereby driving... Roller 14 presses trapezoidal slider 8 to move it longitudinally, and then drives the insertion rod 9 to be inserted into the base for fixation, which facilitates the disassembly and installation of the winch and is applicable to a variety of different models of winch units. Two fixed blocks 21 are provided on the upper surface of the base 2 on one side of the winding drum 6. A threaded rod 22 is installed between the two fixed blocks 21.

A sliding rod 25 is fixedly installed between the two fixed blocks 21 on one side of the threaded rod 22. The sliding rod 25 is slidably connected to the moving block 23. A drive motor 26 is installed on one side of the fixed block 21 and fixedly connected to the threaded rod 22.

[0022] In summary, this easy-to-install winch for sand dredging vessels, through the coordinated arrangement of mounting base 1, base 2, trapezoidal slider 8, insert rod 9, first spring 10, screw 11, threaded sleeve 12, fixing plate 13, roller 14, worm gear, 15 protective cover 16, worm 17, knob 18, limiting frame 19, and second spring 20, allows for easy installation. The mounting base 1 is fixed to the deck of the sand dredging vessel, and the base 2 is placed on the mounting base 1 with the horizontal plates on both sides abutting against it. Rotating the knob 18 drives the worm 17 to rotate, which in turn drives the screw 11 to rotate. As the screw 11 rotates, the threaded sleeve 12 moves laterally along the limiting frame 19, causing the roller 14 to press the trapezoidal slider 8 longitudinally. Subsequently, the insert rod 9 is inserted into the base for fixation, facilitating the disassembly and installation of the winch. It is suitable for various models of winch units.
