Description

Technical Field

[0001] The utility model relates to the technical field of power supply cables for gantry hoisting equipment, in particular to a cable reversing device for a machine. Background Art

[0002] Onboard cables are cables installed between the ship's superstructure and onboard equipment, mainly used to transmit power, signals and data. During the operation of the ship, the cables may be damaged by vibration, friction or external impact. The reversing device can reduce the stress concentration of the cable and avoid cable damage caused by excessive stretching, extrusion or bending.

[0003] Traditional cable reversing devices usually rely on mechanical structures to achieve cable steering to ensure that the cable will not be excessively bent or damaged during movement or vibration. Traditional reversing devices usually include a series of mechanical components such as pulleys, guide rails, and clamps. When the cable passes through these components, it can change direction to adapt to the movement of the equipment or the tilt of the ship. The cable is usually fixed in the reversing device through clamps or straps to ensure that the cable remains stable during the reversing process and reduce cable damage caused by vibration or movement. Traditional reversing devices may require manual operation to achieve cable reversal, or use a simple mechanical linkage system to achieve semi-automatic reversing.

[0004] The above-mentioned traditional on-machine cable reversing device, if the reversing device is improperly designed or operated, may cause cable damage and increase the risk of electrical failure. The traditional reversing device may not be able to quickly respond to the cable reversing needs, especially in situations where frequent reversing is required, which may affect operating efficiency.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 - Figure 3 The utility model provides an embodiment: an upper machine cable reversing device, comprising a base 1, a support body 3 is fixedly connected to the upper surface of the base 1, a lower connecting block 5 is fixedly connected to the upper surface of the support body 3, an upper connecting block 10 is arranged on the outer wall of the lower connecting block 5, a bolt 11 is threadedly connected to the inner part of the upper connecting block 10, an outer wall of the bolt 11 is threadedly connected to the inner part of the lower connecting block 5, a protective sleeve 13 is arranged inside the lower connecting block 5, a cable 12 is arranged inside the protective sleeve 13, a support block 4 is fixedly connected to the upper surface of the base 1, a bearing 7 is fixedly connected to the inner part of the support block 4, a rotating rod 6 is fixedly connected to the inner wall of the bearing 7, an outer wall of the rotating rod 6 is rotatably connected to the inner part of the support block 4, a first rotating plate 8 is fixedly connected to the outer wall of the rotating rod 6, and a fixing component is arranged on the outer wall of the rotating rod 6.

[0025] Specifically, first, pass the cable 12 through the protective sleeve 13, and clamp the protective sleeve 13 together with the cable 12 between the upper connecting block 10 and the lower connecting block 5. Through the threaded connection of the bolt 11, the position of the cable 12 and the protective sleeve 13 can be adjusted and fixed, so as to initially protect the cable 12 from external damage and ensure the stability of the cable 12 during the reversing process. The support block 4 is fixed on the base 1, and a bearing 7 is installed inside it. The inner wall of the bearing 7 is fixedly connected with a rotating rod 6. When the door machine equipment needs to perform a reversing operation, the movement of the door machine equipment will drive the cable 12 and the protective sleeve 13. Since the cable 12 is fixed in the protective sleeve 13, and the protective sleeve 13 is fixed between the upper connecting block 10 and the lower connecting block 5, the movement of the cable 12 will be transmitted to the first rotating plate 8, and the movement of the first rotating plate 8 and the second rotating plate 9 will drive the rotating rod 6 to rotate inside the support block 4. Since the bearing 7 is fixed inside the support block 4, the rotating rod 6 can rotate smoothly under the support of the bearing 7, thereby realizing the reversal of the cable 12. During the entire reversing process, the protective sleeve 13 and the fixed structure can protect the cable 12 and prevent the cable 12 from being damaged by external factors, while ensuring the stability of the cable 12 during reversing.

[0026] Reference Figure 1 and Figure 4 The fixing assembly includes a first rotating block 14, the interior of the first rotating block 14 is fixedly connected to the outer wall of the rotating rod 6, the outer wall of the first rotating block 14 is fixedly connected to the second rotating plate 9, the outer wall of the second rotating plate 9 is fixedly connected to the second rotating block 15, the interior of the second rotating block 15 is fixedly connected to the outer wall of the rotating rod 6, the outer wall of the lower connecting block 5 is fixedly connected to the outer wall of the second rotating plate 9, the upper surface of the base 1 is fixedly connected to the first supporting column 2, one end of the first supporting column 2 is fixedly connected to the first fixing plate 16, and the upper surface of the first fixing plate 16 is fixedly connected to the second fixing plate 1 7. The upper surface of the first fixed plate 16 is fixedly connected with the first clamping block 18, the upper surface of the second fixed plate 17 is fixedly connected with the fixing block 21, the interior of the fixing block 21 is rotatably connected with the special-shaped block 22, the outer wall of the special-shaped block 22 is rotatably connected with the connecting plate 23, one end of the connecting plate 23 is rotatably connected with the connecting rod 20, the outer wall of the connecting rod 20 is slidably connected to the interior of the fixing block 21, one end of the connecting rod 20 is fixedly connected with the second clamping block 19, the outer wall of the second clamping block 19 is fixedly connected with the sliding block 24, and the outer wall of the sliding block 24 is slidably connected to the interior of the first clamping block 18.

[0027] Specifically, the first clamping block 18 and the second clamping block 19 are fixed on the first fixing plate 16 and the second fixing plate 17 respectively, and a space for fixing the tail of the cable 12 is formed between them. The slider 24 is located inside the first clamping block 18 and can slide along the outer wall of the first clamping block 18. The connecting plate 23 is rotatably connected with the special-shaped block 22. The special-shaped block 22 is located inside the fixing block 21 and can rotate. The tail of the cable 12 and the protective sleeve 13 is placed between the first clamping block 18 and the second clamping block 19, and then the special-shaped block 22 is pulled forward to drive the connecting plate 23 to move forward. The movement of the connecting plate 23 causes the connecting rod 20 to slide inside the fixing block 21, thereby driving the second clamping block 19 to slide along the first clamping block 18. The slider 24 slides inside the first clamping block 18 as the second clamping block 19 moves, ultimately achieving the clamping and fixing of the tail of the cable 12. Through the above fixing and clamping process, the tail of the cable 12 is firmly fixed between the clamping blocks, preventing the cable 12 from being damaged due to friction between the cable 12 and the ground during the switching process.

[0028] Working principle: When it is necessary to use an upper machine cable reversing device, first, the cable 12 is sheathed inside the protective sleeve 13, and the protective sleeve 13 and the cable 12 are clamped inside the upper connecting block 10 and the lower connecting block 5 to fix them, which plays a role in preliminarily protecting the cable 12 from external damage and fixing the cable 12. When the door machine equipment is reversed, the cable 12 and the protective sleeve 13 are driven by the door machine equipment to make the first rotating plate 8 and the second rotating plate 9 drive the rotating rod 6 to rotate inside the support block 4. The bearing 7 is fixed inside the support block 4 so that the rotating rod 6 can rotate smoothly, thereby achieving the reversing effect. By placing the cable 12 and the protective sleeve 13 on the first clamping block 1 8 and the interior of the second clamping block 19 are used to fix the tail cable 12, and the connecting plate 23 is driven forward by pushing the special-shaped block 22 forward, and the connecting rod 20 is driven to slide inside the fixed block 21 by the forward movement of the connecting plate 23, and the second clamping block 19 is driven to slide above the first clamping block 18 by the forward sliding of the connecting rod 20, and the slider 24 is driven to slide inside the first clamping block 18 by the first clamping block 18. By placing the tail cable 12 and the protective cover 13 inside the first clamping block 18 and the second clamping block 19, the tail cable 12 is clamped and fixed, preventing the cable 12 from rubbing against the ground during the switching process and causing damage to the cable 12.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
