Description

Technical Field

[0001] This invention relates to the field of port machinery power supply equipment technology, and specifically discloses a simple online device. Background Technology

[0002] In many situations, when a large mobile device needs to be charged, the cable has to be dragged down for charging. This is inconvenient and can accelerate the wear or damage of the cable surface. Moreover, it often requires two people to work together to pull a relatively long cable down from above.

[0003] In the past, there were two methods for temporarily drawing power from large equipment:

[0004] (1) Using a long cable for transition. This means that each time it is used, someone needs to go to the corresponding power source on the equipment and send the power to the ground through the long cable, and then a person on the ground needs to collect the power. It requires manual pulling of a long cable from a height to the ground, which poses a risk of objects being thrown from a height and is prone to causing wear and tear on the cable surface;

[0005] (2) A simple cable reel is installed on the large equipment, and the cable is delivered to the ground by winding up and down the reel. This method is currently the mainstream approach. It solves the problem of having to send people to the corresponding positions on the large equipment to perform dangerous actions, while protecting the safety of personnel below and preventing damage to the cable. However, this method has a drawback: because the cable needs to be wound on the reel, the diameter of the reel is required due to the minimum bending radius requirement of the cable, especially when the power cable diameter is large, the diameter of the reel will also increase accordingly. This increases the installation difficulty of large structures and requires more installation space. At the same time, repeated bending of the cable will also affect its service life. Summary of the Invention

[0006] This invention proposes a simple cable loading device where the cable is laid flat in a single layer on the reel, eliminating repeated bending and extending its lifespan. The combination of aluminum profiles and resin materials reduces the overall weight, and the reel diameter is unaffected by the cable diameter, making it highly versatile. The I-shaped resin reel and bundling hole design are adapted to different cable diameters, the lightweight structure reduces the load, and the detachable swing arm improves maintenance efficiency. Overall, it has the advantages of high efficiency, safety, and low maintenance costs.

[0007] The present invention is implemented as follows: a simple online device includes an upper steel base;

[0008] A rocker arm device includes a main hinge seat fixedly connected to the lower end of an upper steel base. A milling piece is movably connected to the inner side of the main hinge seat via a pin.

A connector is movably connected to the top of the vertical section of the milling piece via a hinge. A swing arm is provided at the other end of the horizontal section of the milling piece.

[0009] A reel, which is fixedly connected to the other end of the swing arm;

[0010] A drive assembly, comprising a telescopic rod, wherein a drive motor for driving the telescopic rod to extend or retract is mounted on the outer wall of the telescopic rod.

[0011] As a preferred embodiment of the simple online device of the present invention, the lower end face of the upper steel base is fixedly connected to a secondary hinge seat, one end of the telescopic rod is movably connected to the inner side of the secondary hinge seat and the other end is fixedly connected to the connector.

[0012] As a preferred embodiment of the simple online device of the present invention, the reel has an I-shaped cross-section and is made of resin.

[0013] As a preferred embodiment of the simple online device of the present invention, the outer perimeter of the reel is provided with a plurality of evenly distributed binding holes, the diameter of the reel is in the range of 200mm to 300mm, the diameter of the binding holes is 1.2-1.5 times the diameter of the cable, the spacing between the holes is 3-5 times the diameter of the cable, and the inner perimeter of the reel is provided with a plurality of evenly distributed fan-shaped holes.

[0014] As a preferred embodiment of the simple online device of the present invention, the swing arm is detachably connected to the milling part by bolts.

[0015] As a preferred embodiment of the simple online device of the present invention, the outer wall of the reel is coated with an antistatic coating.

[0016] As a preferred embodiment of the simplified online device of the present invention, the drive motor is a servo motor.

[0017] The beneficial effects of this invention are:

[0018] This device uses a drive motor to drive the telescopic rod in a linear motion, combined with an L-shaped milling part and a hinge mechanism to achieve reel lifting and lowering, significantly reducing cable bending wear and extending its lifespan. The cable is laid flat on the reel in a single layer, without repeated bending, further extending its lifespan. The combination of aluminum profiles and resin materials reduces the overall weight, and the reel diameter is not affected by the cable diameter, making it highly versatile.

An anti-static coating eliminates the risk of frictional static electricity, a servo motor precisely controls the lifting height, and a detachable swing arm improves maintenance efficiency. Overall, it has the advantages of high efficiency, safety, and low maintenance costs, making it suitable for harsh operating scenarios such as port machinery. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figure 1-5 A simple online device includes an upper steel base 1;

[0028] The rocker arm device includes a main hinge seat 2 fixedly connected to the lower end of the upper steel base 1. The inner side of the main hinge seat 2 is movably connected to a milling piece 4 via a pin 3. The milling piece 4 has an L-shaped structure and the pin 3 is located at the intersection of the horizontal and vertical sections of the milling piece 4. The top of the vertical section of the milling piece 4 is movably connected to a connector 6 via a hinge 5. The other end of the horizontal section of the milling piece 4 is provided with a swing arm 13.

[0029] Reel 7 is fixedly connected to the other end of swing arm 13;

[0030] The drive assembly includes a telescopic rod 9, and a drive motor 10 for driving the telescopic rod 9 to extend and retract is mounted on the outer wall of the telescopic rod 9.

[0031] In this embodiment: the drive motor 10 drives the telescopic rod 9 to extend and retract linearly. The telescopic rod 9 has a screw and nut mechanism inside. The drive motor 10 outputs rotational power. The screw is connected to the output end of the drive motor 10. The nut is threaded with the screw and fixed inside the telescopic rod. The rotation of the motor drives the screw to rotate. Furthermore, the nut moves linearly along the screw thread direction, thereby driving the telescopic rod 9 to extend or retract. Through the hinge relationship between the secondary hinge seat 11 and the connector 6, the milling part 4 is pushed to swing around the pin 3 of the main hinge seat 2, thereby driving the swing arm 13 and the reel 7 to rise and fall. Then, the cable wound on the reel 7 is removed for charging. After charging is completed, it is wound on the reel. At this time, the cable rocker arm rises and is parallel to the plane of the upper steel structure. The cable is laid flat on the reel in a single layer without repeated bending action, which extends the service life. The combination of aluminum profile and resin material reduces the overall weight. The diameter of the reel is not affected by the diameter of the cable, which makes it highly versatile.

[0032] The cable is laid flat in a single layer on the I-shaped resin reel 7 and fixed by the binding hole 8 to avoid bending and tangling. The fan-shaped hole 12 reduces weight and enhances heat dissipation.

[0033] The L-shaped milled part 4 and the detachable swing arm 13 form a stable transmission chain, and the drive motor 10 precisely controls the travel of the telescopic rod to ensure that the lifting height of the reel is adapted to the needs of manual operation.

[0034] As a technical optimization of the present invention, a secondary hinge seat 11 is fixedly connected to the lower end face of the upper steel base 1, and one end of the telescopic rod 9 is movably connected to the inner side of the secondary hinge seat 11 and the other end is fixedly connected to the connector 6.

[0035] In this embodiment: the secondary hinge seat 11 fixes one end of the telescopic rod 9, and the other end is hinged to the connector 6, forming a stable power transmission path, enhancing transmission stability, preventing the telescopic rod from deviating, and extending the service life of the device.

[0036] As a technical optimization of the present invention, the reel 7 has an I-shaped cross-section and is made of resin.

[0037] In this embodiment, the I-shaped resin reel 7 has optimized load-bearing capacity through cross-sectional structure and reduced weight due to the resin material.

[0038] As a technical optimization of the present invention, the outer perimeter of the reel 7 is provided with a plurality of evenly distributed binding holes 8. The diameter of the reel 7 is in the range of 200mm to 300mm. The diameter of the binding holes 8 is 1.2-1.5 times the diameter of the cable, and the spacing between the holes is 3-5 times the diameter of the cable. The inner perimeter of the outer perimeter of the reel 7 is provided with a plurality of evenly distributed fan-shaped holes 12.

[0039] In this embodiment: the bundling holes 8 are distributed according to the cable diameter ratio to avoid local stress concentration when fixing the cable; the fan-shaped holes 12 reduce the weight of the reel, adapt to cables of different diameters, and extend the cable life.

[0040] As a technical optimization of the present invention, the swing arm 13 is detachably connected to the milling part 4 by bolts.

[0041] In this embodiment, the swing arm 13 is connected to the milling part 4 by bolts, which can be quickly disassembled and replaced, improving maintenance convenience, shortening downtime, and reducing operation and maintenance costs.

[0042] As a technical optimization of the present invention, the outer wall of the reel 7 is coated with an antistatic coating.

[0043] In this embodiment: an antistatic coating covers the surface of reel 7 to eliminate static electricity generated by cable friction and avoid safety hazards caused by electrostatic sparks.

[0044] As a technical optimization of the present invention, the drive motor 10 is a servo motor.

[0045] In this embodiment, the drive motor 10 can adjust the travel of the telescopic rod 9 in real time through encoder feedback.

[0046] The working principle and usage process of this invention: The drive motor 10 drives the telescopic rod 9 to extend and retract linearly. The telescopic rod 9 has a screw and nut mechanism inside. The drive motor 10 outputs rotational power. The screw is connected to the output end of the drive motor 10. The nut is threaded with the screw and fixed inside the telescopic rod. The rotation of the motor drives the screw to rotate. Furthermore, the nut moves linearly along the screw thread direction, thereby causing the telescopic rod 9 to extend or retract. Through the hinge relationship between the secondary hinge seat 11 and the connecting head 6, the milling part 4 is pushed to swing around the pin 3 of the main hinge seat 2, thereby driving the swing arm 13 and the reel 7 to rise and fall. Then, the cable wound on the reel 7 is removed for charging. After charging is completed, it is wound back on the reel. At this time, the cable swing arm rises and is parallel to the plane of the upper steel structure.
