Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and more particularly to a rope-climbing machine for the rapid lifting of water pumps. Background Technology

[0002] In the field of ship operations, water pumps are crucial drainage and water supply equipment, and their hoisting operations are involved in various stages of ship maintenance and emergency drainage. For example, when a ship is undergoing repairs at the dock or working in the dry dock, water pumps often need to be lifted from the dock surface or dry dock to the deck; conversely, when water accumulates in the hold (such as the main hold) and needs to be pumped out, the water pumps need to be quickly lowered from the hatch to the bottom of the hold. Traditional methods of hoisting water pumps mostly rely on manual handling or the ship's own lifting equipment. However, manual handling is not only labor-intensive and inefficient, but also poses safety hazards due to the weight of the water pumps. The ship's own lifting equipment is limited by operating space and scope, making it difficult to operate flexibly in confined areas such as hatches and failing to meet the needs of rapid hoisting. Rope climbing machines are a type of handling tool, generally used for moving goods and people up and down, allowing goods to reach difficult-to-move locations or people to reach and secure in inconvenient locations. Rope climbing machines are small in size, easy to carry and deploy, and suitable for use in areas with limited operating space and scope during ship operations.

[0003] The rope climbing machine mainly consists of a drive assembly, a rope clamping mechanism, a load-bearing hook, and a control unit. Its working principle is that the rope clamping mechanism works closely with the preset load-bearing rope, and under the drive of the drive assembly, it achieves stable lifting and lowering along the rope, thereby completing the hoisting operation of the water pump through the load-bearing hook.

[0004] Regarding the aforementioned and existing related technologies, the inventors believe that the following drawbacks often exist: Existing rope climbing machines typically have a self-locking structure to prevent the equipment from falling in the event of power failure, malfunction, or sudden load changes. Currently, most rope climbing machines achieve self-locking through the friction between the friction wheel and the rope. This reliability is highly dependent on the pressure stability and contact surface condition between the friction wheel and the rope. If the rope surface is contaminated with oil, has uneven wear, or the spring pressure decreases due to long-term use, the static friction may drop significantly, making it difficult to ensure effective locking under heavy loads or emergency situations, posing certain safety hazards. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the self-locking technology in the prior art is highly dependent on the pressure between the friction wheel and the rope, which makes it difficult to ensure effective locking under heavy load or emergency conditions. To this end, we propose a rope climbing machine for rapid lifting of water pumps.

[0006] To achieve the above objectives, this application adopts the following technical solution: a rope-climbing machine for rapid lifting of water pumps, comprising a housing and a rope wheel. The rope wheel is rotatably connected to the inner side of the housing and near the top. A motor is installed inside the housing 1, and the motor shaft is connected to the rope wheel 2, driving the rope wheel 2 to rotate. A guide wheel is rotatably connected to the middle of the inner cavity of the housing. The rope wheel is higher than the guide wheel. A rope is wound around both the rope wheel and the guide wheel. Both ends of the rope extend to the outside of the housing. The middle of the rope bends through the rope wheel and the guide wheel and extends horizontally to form an upper extrusion section and a lower extrusion section. The upper extrusion section and the lower extrusion section are aligned vertically. An extrusion block is provided at the top of the upper extrusion section, and a fixing block is provided at the bottom of the lower extrusion section. An extrusion groove with the same orientation as the lower extrusion section is opened at the top of the fixing block. The lower extrusion section is movably connected in the extrusion groove. The extrusion groove is aligned vertically with and adapted to the extrusion block. A driving component for driving the extrusion block to move up and down is provided in the inner cavity of the housing, and the extrusion block is mounted on the driving component.

[0007] Preferably, the top and side walls of the outer shell are provided with inlet and outlet openings, and the two ends of the rope are respectively movably sleeved in the inlet and outlet openings on both sides and pass through the outside of the outer shell.

[0008] Preferably, the driving component includes two slide rails, which are respectively fixedly connected to both sides of the inner wall of the housing. Electric sliders are fixedly connected to the surfaces of both slide rails. A connecting plate is fixedly connected to the opposing sides of the two electric sliders. A connecting block is fixedly connected to the bottom surface of the connecting plate. The bottom surface of the connecting block is fixedly connected to the top surface of the extrusion block.

[0009] Preferably, a connecting frame is provided at the upper end of the inner cavity of the outer shell, a tensioning wheel is rotatably connected to the inner side of the connecting frame, the upper end of the rope extends horizontally after being bent by the rope wheel to form a tensioning part, the bottom of the tensioning wheel is in contact with the top of the tensioning part, a support plate is fixedly connected to the outer wall of the connecting frame, and the bottom of the support plate is fixedly connected to the top surface of the connecting plate.

[0010] Preferably, a support wheel is rotatably connected to the inner wall of the outer shell. The support wheel is located between the upper extrusion part and the lower extrusion part and is horizontally opposite to the guide wheel. The end of the upper extrusion part near the rope wheel is wrapped around the support wheel to reduce the probability that the end of the upper extrusion part in contact with the rope wheel will detach from the rope wheel due to downward extrusion.

[0011] Preferably, the extrusion block and the upper extrusion part are fixedly connected to two limiting blocks on the same sides, the two limiting blocks are aligned vertically with the upper extrusion part, and each limiting block has a limiting groove at its bottom, the limiting groove being aligned vertically with and adapted to the upper extrusion part.

[0012] Preferably, the inner wall of the extrusion groove and the bottom surface of the extrusion block are provided with anti-slip texture, and a gap of 0.5mm to 1cm is left between the lower extrusion part and the extrusion groove.

[0013] Preferably, an acceleration sensor is fixedly connected to the inner wall of the housing, and the acceleration sensor is electrically connected to the electric slider.

[0014] The technical effects and advantages of this invention are as follows:

[0015] In this invention, the compression block applies pressure to the rope to achieve a preliminary braking effect, and the upper and lower compression parts of the rope are pressed against each other in the compression groove. Since the surface of the rope is rough and easily deformed under pressure, significant frictional resistance is generated, which effectively prevents the rope from moving in the compression groove, thereby enhancing the braking performance during descent.

[0016] In this invention, the rope is tightened by lowering the tensioning pulley and applying downward pressure to the tensioned part of the rope, so that the part of the rope wrapped around the pulley fits more tightly with the pulley, thereby ensuring stable friction between the rope and the pulley and effectively reducing the risk of slippage.

[0024] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0025] Reference Figure 1-5 As shown, the present invention provides a technical solution: a rope climbing machine for rapid hoisting of water pumps, comprising a housing 1 and a rope wheel 2. The rope wheel 2 is rotatably connected to the inner side of the housing 1 and near the top. A guide wheel 3 is rotatably connected to the middle of the inner cavity of the housing 1. The rope wheel 2 is higher than the guide wheel 3. A rope 4 is wound around the rope wheel 2 and the guide wheel 3. Both ends of the rope 4 extend to the outside of the housing 1. The middle of the rope 4 is bent through the rope wheel 2 and the guide wheel 3 and extends horizontally to form an upper extrusion part 41 and a lower extrusion part 42. The upper extrusion part 41 and the lower extrusion part 42 are aligned vertically. An extrusion block 5 is provided at the top of the upper extrusion part 41. A fixing block 6 is provided at the bottom of the lower extrusion part 42. An extrusion groove 7 with the same orientation as the lower extrusion part 42 is opened at the top of the fixing block 6. The lower extrusion part 42 is movably connected in the extrusion groove 7. The extrusion groove 7 is aligned vertically with and adapted to the extrusion block 5. A driving member 8 for driving the extrusion block 5 to move up and down is provided in the inner cavity of the housing 1. The extrusion block 5 is mounted on the driving member 8. The extrusion block 5 descends and pushes the upper extrusion part 41 into the extrusion groove 7. The extrusion block 5 simultaneously extrudes the upper extrusion part 41 and the lower extrusion part 42, and the upper extrusion part 41 and the lower extrusion part 42 also extrude each other.

[0026] The top and side walls of the outer casing 1 are provided with access openings 9. The two ends of the rope 4 are respectively movably sleeved in the access openings 9 on both sides and pass through the outside of the outer casing 1. The rope 4 passes through the access openings 9 from inside the outer casing 1 and moves vertically up and down along the rope 4.

[0027] The driving component 8 includes two slide rails 81, which are fixedly connected to both sides of the inner wall of the housing 1. Electric sliders 82 are fixedly connected to the surfaces of both slide rails 81. A connecting plate 83 is fixedly connected to the opposing sides of the two electric sliders 82. A connecting block 84 is fixedly connected to the bottom surface of the connecting plate 83, and the bottom surface of the connecting block 84 is fixedly connected to the top surface of the extrusion block 5. The electric sliders 82 can slide up and down on the surfaces of the slide rails 81, thereby controlling the up and down movement of the extrusion block 5.

[0028] A connecting frame 10 is provided at the upper end of the inner cavity of the outer casing 1. A tensioning wheel 11 is rotatably connected to the inner side of the connecting frame 10. The upper end of the rope 4 extends horizontally after being bent by the rope wheel 2, forming a tensioning part 43. The bottom of the tensioning wheel 11 is in contact with the top of the tensioning part 43. A support plate 12 is fixedly connected to the outer wall of the connecting frame 10, and the bottom of the support plate 12 is fixedly connected to the top surface of the connecting plate 83. When the tensioning wheel 11 moves downward, it will squeeze the tensioning part 43 of the rope 4, thereby tightening the rope 4 and making the part of the rope 4 wrapped around the rope wheel 2 tighter with the rope wheel 2.

[0029] A support wheel 13 is rotatably connected to the inner wall of the outer casing 1. The support wheel 13 is located between the upper extrusion part 41 and the lower extrusion part 42 and is horizontally opposite to the guide wheel 3. The end of the upper extrusion part 41 near the rope wheel 2 is wrapped around the support wheel 13 to reduce the probability that the end of the upper extrusion part 41 in contact with the rope wheel 2 will detach from the rope wheel 2 due to downward extrusion.

[0030] Both sides of the extrusion block 5 and the upper extrusion part 41 are fixedly connected to limiting blocks 14. Both limiting blocks 14 are vertically aligned with the upper extrusion part 41. Each limiting block 14 has a limiting groove 15 at its bottom, which is vertically aligned with and fits the upper extrusion part 41. When the extrusion block 5 descends, the limiting blocks 14 descend accordingly and fit the upper extrusion part 41 into the limiting groove 15. The limiting groove 15 prevents the lower end of the rope 4, which is mounted on the rope wheel 2, from moving horizontally and falling off the rope wheel 2.

[0031] The inner wall of the extrusion groove 7 and the bottom surface of the extrusion block 5 are both provided with anti-slip textures, and a gap of 0.5mm to 1cm is left between the lower extrusion part 42 and the extrusion groove 7. This gap ensures that the rope 4 will not come into contact with the extrusion groove 7 during normal operation of the rope climbing machine, avoiding friction and thus extending the service life of the rope 4.

[0032] An acceleration sensor 16 is fixedly connected to the inner wall of the outer casing 1. The acceleration sensor 16 is electrically connected to the electric slider 82. When the acceleration sensor 16 detects that the slider is rapidly descending, it will drive the electric slider 82 to start and slide downward. A lifting ring is fixedly connected to the bottom of the outer casing 1. The lifting ring can be used to suspend goods. A wireless module is installed inside the outer casing 1. The operation of the electric slider 82 and other electrical components can be remotely controlled through the wireless module.

[0033] Working Principle: When the rope climbing machine slips on rope 4 and begins to fall, the falling speed far exceeds the threshold set by the acceleration sensor 16. Upon receiving this data, the acceleration sensor 16 immediately sends a signal to the electric slider 82. Upon receiving the signal, the electric slider 82 slides downwards along the slide rail 81, thereby causing the connecting plate 83 and connecting block 84 to descend together. As the connecting block 84 moves, the compression block 5 is also driven downwards, applying downward pressure to the upper compression part 41 of the rope 4, forcing it to descend and enter the compression groove 7. During this process, the compression block 5 simultaneously compresses and fixes both the upper compression part 41 and the lower compression part 42 of the rope 4, achieving a preliminary braking effect. Simultaneously, the upper compression part 41 and the lower compression part 42 of the rope 4 compress each other within the compression groove 7. Due to the rough surface of the rope 4 and its tendency to deform under pressure, significant frictional resistance is generated, effectively preventing the rope 4 from moving within the compression groove 7, thereby enhancing the braking performance during descent. Furthermore, if the rope 4 gradually loosens between the rope pulleys 2 due to prolonged use, the connecting plate 83 can be moved downwards by controlling the electric slider 82 to slide downwards on the slide rail 81. The descent of the connecting plate 83 will cause the support plate 12 and the connecting frame 10 to move downwards together, thereby causing the tensioning pulley 11 to descend and apply downward pressure to the tensioning part 43 of the rope 4. After being pressed, the tensioning part 43 will tighten the rope 4, making the part of the rope 4 wrapped around the rope pulley 2 fit more tightly with the rope pulley 2, thereby ensuring stable friction between the rope 4 and the rope pulley 2 and effectively reducing the risk of slippage.

[0034] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
