Description

Technical Field

[0001] The utility model relates to the technical field of cable reels, in particular to an anti-falling device for a cable reel. Background Art

[0002] In the past, ships moored at the dock had to use the ship's diesel generators to generate electricity around the clock to meet the ship's electricity needs. Diesel generators burn a lot of fuel and emit a lot of exhaust gas during operation, while also generating noise pollution around the clock. In order to solve this problem, a ship's shore-based power supply system (hereinafter referred to as the shore power system) can be used to supply power to ships moored at the dock. The power output by the shore power system needs to be connected to the ship power system using a cable transmission system to achieve the purpose of supplying shore-side power to the ship side. The power supply device from the shore power system to the ship power system includes a cable connection box, a cable reel, a cable tray, a cable guide frame, a control box, and a wired and / or wireless controller for the ship-side control cable reel system. However, the cable reel is relatively slow to assemble and is prone to loosening after assembly. In addition, when the motor drives the reel to reel, it is easy to transmit vibration to the reel frame, causing shaking, which poses a safety hazard.

[0003] For example, a cable reel with an anti-falling function with publication number CN211225887U solves the problem in the prior art that the cable reel is slow to assemble and is prone to loosening after assembly. In addition, when the motor drives the reel to reel, it is easy to transmit vibration to the reel frame, causing shaking and posing a safety hazard. It includes a concave frame, the upper surface of the concave frame is equipped with an I-shaped reel, the interior of the I-shaped reel is equipped with an inner rotating column, the inner side of the concave frame is provided with a rotating groove corresponding to the positions of the two ends of the inner rotating column, and the inner rotating column is located inside the rotating groove, the outer side of the I-shaped reel is equipped with a mounting seat, the upper surface of the mounting seat is equipped with a motor seat, the upper surface of the motor seat is equipped with a rotating motor, the upper surface of the two ends of the I-shaped reel is provided with spring grooves, and the interior of the inner rotating column is provided with a bolt through hole.

[0004] The above technical solution can only realize the installation of the matching reel during use, but cannot realize the rapid installation of reels of different specifications, and has a limited scope of use.
