[0002] Self-unloading ship refers to a ship with automatic control device, which can complete unloading operation at high speed and continuously. Workers do not directly participate in operation on the ship, and only need to make necessary adjustment and control to the equipment. The unloading efficiency is high, and the turnover is fast. The ship body itself is provided with an unloading device to unload materials to the wharf. The self-unloading ship has a special cargo hold structure and unloading equipment, and can unload cargo in a continuous conveying manner. The self-unloading ship can concentrate on unloading operation and realize high-speed automatic unloading

[0003] A 26000-ton self-unloading ship is provided with a 12T movable gantry crane on the deck of the cargo hold. The gantry crane can shuttle back and forth at the head and tail to open and close the hatch cover. The gantry crane is normally parked in the middle of the third hold. The power cable of the equipment is pulled from the junction box on the right side of the third hold to the cable drum current collector of the gantry crane. Since the cable needs to be switched in direction at the head and tail during the movement of the gantry crane, in order to protect the cable and avoid the cable being repeatedly bent and damaged during the long-term back-and-forth movement of the gantry crane, a deck gantry crane cable guide is urgently needed to solve the above problems. SUMMARY

[0010] Further, the rotating seat structure further comprises a buffer damping structure for controlling the guide pipe, which is used for slow falling and shock absorption during the swinging pipe end falling on the deck.

[0011] The buffer damping structure comprises a containing cavity formed in the sleeve pipe, the containing cavity is filled with damping oil between the outer wall of the rotating pipe and the inner wall of the containing cavity, a partition plate is fixedly arranged in the containing cavity and arranged along the arrangement direction of the sleeve pipe, a piston plate is arranged on the side wall of the rotating pipe and fixedly connected to one side of the outer wall of the rotating pipe, and the other three sides of the piston plate are connected to the inner wall of the containing cavity; the partition plate and the piston plate divide the containing cavity into chamber one and chamber two, and the rotation of the rotating pipe drives the piston plate to rotate in the containing cavity and changes the volume of the chamber one and the chamber two.

[0012] Further, an oil passing hole is arranged on the piston plate or the rotating plate and connected to the chamber one and the chamber two, and the oil passing hole limits the flow of the damping oil passing through to buffer the guide pipe when the piston plate rotates around the axis of the rotating pipe.

[0016] Compared with the prior art, the beneficial effects of the present application are:

[0017] 1. The present application uses the L-shaped guide pipe sleeve arranged outside the cable to achieve good protection effect on the cable, so as to reduce the abrasion of the cable body when the gantry crane reciprocatingly pulls and turns the cable.

[0018] 2. The metal woven mesh pipe is arranged at the end of the swinging pipe to protect the cable passing through the end of the guide pipe, and the metal woven mesh pipe can be wrapped outside the cable to make the cable have an arc when being pulled and not be damaged by bending.

[0019] 3. With the buffer damping structure, when the gantry crane pulls the guide tube to turn via the cable, it will not fall onto the deck under the action of gravity. The buffer damping structure allows the swing tube of the guide tube to fall onto the deck slowly with a certain damping. This can reduce the noise caused by the swing tube hitting the deck, and also protect the internal cable lines from vibration by avoiding the vibration caused by hitting the deck.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Example 1

[0030] A deck gantry crane cable guide, comprising a guide pipe 1 for threading a cable, the guide pipe 1 being internally hollowed to provide a cable hole 2 for the cable to pass through, the guide pipe 1 comprising a rotating pipe 3 and a swinging pipe 4; the device is arranged on the deck, the cable line of the gantry crane passes through the cable hole 2 in the guide pipe 1, and the guide pipe 1 protects the cable; when the gantry crane is moving, the cable line will be pulled to rotate, and the device protects the cable from being repeatedly bent in the arc-shaped bend pipe 6, avoids damage to the cable, and provides guidance for the arrangement of the cable.

[0031] The rotating seat structure comprises a sleeve pipe 5 sleeved outside the rotating pipe 3, the sleeve pipe 5 is coaxially arranged with the rotating pipe 3, and the guide pipe 1 is rotationally connected relative to the sleeve pipe 5; the sleeve pipe 5 is connected by a fixed part and arranged on the deck of the ship body, and the sleeve pipe 5 is wrapped outside the rotating pipe 3 to maintain the stable rotation of the guide pipe 1; in actual use, when the cable is pulled to rotate by the moving gantry crane, the guide pipe 1 can be assisted to make the guide pipe 1 move and rotate with the cable and protect the cable during rotation, which is beneficial to the long-term use of the cable; the rotating pipe 3 and the swinging pipe 4 are arranged perpendicular to each other, and the arc-shaped bend pipe 6 for smooth connection transition is arranged between the rotating pipe 3 and the swinging pipe 4; the arc-shaped bend pipe 6 can make the cable line passing through it rotate smoothly, so that the cable line can smoothly pass through the guide pipe 1 without being bent; a metal woven mesh pipe 7 can also be arranged at the end of the swinging pipe 4; since metal wires are woven, the metal woven mesh pipe 7 has a certain supporting capacity, so that the cable passing through the swinging pipe 4 is supported and protected from the outside of the cable.

[0032] As shown in Figure 2 , the fixed part comprises a plurality of ear plates 8 fixedly connected on both sides of the sleeve pipe 5, a plurality of angle steel connecting seats 9 are fixedly arranged on the deck, the angle steel connecting seats 9 can be fixedly welded on the deck, the rotating seat structure is installed on the angle steel connecting seats 9 through the ear plates 8, the rotating seat structure can be fixedly arranged on the deck of the ship body by fixed bolts penetrating through the ear plates 8 and the angle steel connecting seats 9, and the arrangement position and number of the angle steel connecting seats 9 are matched with the ear plates 8.

[0033] As shown in Figure 1 , two limiting stop rings 10 are fixedly arranged on the rotating pipe 3, and the limiting stop rings 10 are arranged at both ends of the sleeve pipe 5, respectively; the limiting stop rings 10 limit the axial movement of the rotating pipe 3; a lubricating gap 22 is arranged between the inner wall of the sleeve pipe 5 and the rotating pipe 3, an oil injection nozzle 11 is arranged on the sleeve pipe 5 and communicates with the lubricating gap 22, and lubricating oil can be injected into the lubricating gap 22 from the oil injection nozzle 11 to lubricate the lubricating gap 22, so that the guide pipe 1 rotates flexibly.

[0034] Example two:

[0035] As the rotation of the guide pipe 1 in the first embodiment is not limited, it is easy to pull the guide pipe 1 from one side to the central vertical position, and then the subsequent swing pipe 4 will be affected by its own gravity and will accelerate to the other side, and the dumping process is not limited, so it can also pull the cable to cause damage in long-term use, and the falling on the deck will also produce more noise, as an improvement, the rotating seat structure also includes a buffer damping structure for controlling the guide pipe 1, which is used for the slow falling shock absorption of the swing pipe 4 during the falling on the deck, and the swing pipe 4 can be buffered when it falls to the other side after passing the highest point, achieving the effect of slow falling;

[0036] Specifically, the buffer damping structure includes a receiving cavity 12 formed inside the outer sleeve pipe 5. Compared with the first embodiment, the inner wall of the outer sleeve pipe 5 in the first embodiment is basically attached to the rotating pipe 3. In this embodiment, a gap is formed between the two to form the receiving cavity 12, and in actual use, the receiving cavity 12 is filled with damping oil between the outer wall of the rotating pipe 3. It can be understood that the two ends of the outer sleeve pipe 5 for the rotating pipe 3 to pass through are support parts for rotating connection. This part can be supported by a bearing, and attention should be paid that the outer side of the bearing support can apply oil seal to the damping oil.

[0037] As shown in Figure 3 , Figure 4 , a partition plate 13 is fixedly arranged in the receiving cavity 12. The partition plate 13 is arranged along the arrangement direction of the outer sleeve pipe 5, so that the side wall of the partition plate 13 is as close as possible to the outer wall of the rotating pipe 3. The side wall of the rotating pipe 3 is provided with a piston plate 14, one side of the piston plate 14 is fixedly connected to the outer wall of the rotating pipe 3, and the other three side edges are connected to the inner wall of the receiving cavity 12. The three side edges of the piston plate 14 should be as close as possible to the inner wall of the receiving cavity 12. The partition plate 13 and the piston plate 14 divide the receiving cavity 12 into chamber one 15 and chamber two 16. Since the partition plate 13 is close to the rotating pipe 3 and is attached to the rotating pipe 3, and the three side edges of the piston plate 14 are attached to the receiving cavity 12, chamber one 15 and chamber two 16 can be formed independently. The rotation of the rotating pipe 3 drives the piston plate 14 to rotate in the receiving cavity 12 and changes the volume of chamber one 15 and chamber two 16. The change of the volume of the two chambers also causes the mutual conversion of the amount of damping oil contained therein. Therefore, an oil passing hole 17 is provided through the piston plate 14 or the rotating plate. The oil passing hole 17 communicates chamber one 15 and chamber two 16. When the piston plate 14 rotates around the axis of the rotating pipe 3, the oil passing hole 17 limits the flow of damping oil passing through to buffer the guide pipe 1. Since the partition plate 13 is close to the rotating pipe 3 and is attached to the rotating pipe 3, and the three side edges of the piston plate 14 are attached to the receiving cavity 12, a small amount of damping oil can pass through the above-mentioned gap, and most of the damping oil can pass through the oil hole 17. In actual use, a high-viscosity damping oil can be used, or the diameter of the oil hole 17 can be reduced, so as to achieve a better damping effect.

[0038] Embodiment three:

[0039] In embodiment two, the damping effect of the device is not convenient to adjust and change after being assembled, so there is still certain limitation in actual use. As an improvement, a damping adjusting structure is arranged in the embodiment to conveniently adjust the damping effect. As shown in Figure 5 、 Figure 6 、 Figure 7 The damping adjusting structure includes an adjusting block 18 connected to the side wall of one end of the outer sleeve 5. The adjusting block 18 is provided with an adjusting hole 19. A plurality of oil passing pipes 20 are arranged on both sides of the adjusting hole 19 and are communicated with the chamber one 15 and the chamber two 16. The oil passing pipes 20 can be symmetrically arranged on both sides of the adjusting hole 19. The oil passing pipes 20 on the same side of the adjusting hole 19 are communicated with the chamber one 15, and the oil passing pipes 20 on the other side are communicated with the chamber two 16.

[0040] An adjusting rod 21 is arranged in the adjusting hole 19. The depth of the adjusting rod 21 inserted into the adjusting hole 19 is changed to control the number of the oil passing pipes 20 opened. As shown in Figure 6 When the adjusting rod 21 is in the high position, each oil passing pipe 20 is in the open state. At this time, the oil passing area between the chamber one 15 and the chamber two 16 is the largest, so the damping effect is weaker at this time. On the contrary, when the adjusting rod 21 is lowered, the upper oil passing pipe 20 will be blocked. Therefore, as the adjusting rod 21 is lowered, the oil passing area will gradually decrease, thereby gradually improving the damping effect.

[0041] Specifically, an inner thread can be arranged on the inner wall of the adjusting hole 19. The adjusting rod 21 is a adjusting screw. The adjusting screw is connected with the inner thread in meshing connection to realize the up and down movement of the adjusting rod 21. It can be understood that a sealing part can be arranged on the upper end of the adjusting hole 19. The sealing part is used to seal the threaded connection end of the adjusting screw and the inner thread, thereby preventing the damping oil from overflowing from the upper end of the adjusting hole 19.

[0042] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
