The present invention relates to a steel wire rope looseness detection sensor device. The steel wire rope looseness detection sensor device includes an electrical box (1), a contact rod (4), insulating supports (5) and a rope looseness detection circuit. The steel wire rope looseness detection sensor device is characterized in that: the contact rod (4) is mounted on a ground base at one side of a steel wire rope collected and released by a winch (3) through the insulating supports (5); the contact rod (4) is located below the steel wire rope; the rope looseness detection circuit is used for detecting whether the steel wire rope is loose and touches the contact rod (4); the steel wire rope is electrically connected with a grounding (GND) terminal of the rope looseness detection circuit through the rack of the winch (3) and a wire connected onto the rack of the winch (3); and the contact rod (4) is electrically connected with a detection (SENSE) terminal of the rope looseness detection circuit through a wire. The steel wire rope looseness detection sensor device of the invention has the advantages of simple structure, convenient installation and maintenance, low cost, stable operation, high signal detection sensitivity, excellent effects and wide detection range; and the steel wire rope looseness detection sensor device can conveniently perform rope looseness detection when a steel wire rope moves along a rope groove and carries out horizontal movement.
Description
technical field [0001] The invention relates to the technical field of wire rope anti-loosening monitoring, in particular to a wire rope slack detection sensor device. Background technique [0002] With the development of the global economy, the marine transportation industry has also emerged vigorously. The previous way of replenishment at the shore can no longer meet the needs of maritime transportation, and sometimes it is affected by bad sea conditions and bad weather, and ships are often unable to dock for replenishment. directly affects the supply of ship materials. In this case, the ocean-going replenishment of ships is particularly important. When a ship needs to replenish oil, water and other goods in the ocean, it is necessary to establish a wire cable connection between the supply ship and the replenished ship, and establish a supply channel with the help of the steel cable, and realize replenishment or loading and unloading through the supply channel. For the r...
