Embodiment Construction
[0017] Attached below Figure 1 ~ Figure 4 The technical solution of the present invention is further described.
[0018] The wire rope anti-loosening device of the present invention needs to realize three major functions, 1) when the overhead cable needs a certain tension to prevent the delivered goods from falling into the sea due to the sagging of the wire rope; 2) the wire rope anti-loosening device always maintains a certain tension between the overhead cable winch Prevent the rope from appearing in the winch's winding and unwinding; 3) It is used as a pulley when it is not working.
[0019] A specific embodiment of the wire rope anti-loosening device of the present invention is that the device is mainly composed of three major components: a main body frame, a hydraulic transmission mechanism, and a hydraulic clamping mechanism. The main frame is a square box structure welded by multiple plates. In order to ensure the strength, a total of 4 triangular rib plates are weld...

The invention relates to a steel wire rope loosening prevention device which comprises a main rack, a transmission mechanism and a clamping mechanism. The steel wire rope loosening prevention device is characterized in that the transmission mechanism a rotating actuator (1), a steel wire rope pulley (26) and two annular friction plates (28). The clamping mechanism comprises a right brake arm (11), a left brake arm (12), roller bearings (16) and a linear actuator (19). The linear actuator (19) can push the right brake arm (11) and the left brake arm (12) to be close to the friction plates (28) at the same time and press the two friction plates (28) through the two roller bearings (16) to compress a steel wire rope inwards. According to the steel wire rope loosening prevention device, the friction plates are clamped through the roller bearings, and therefore the twisting force of the steel wire rope pulley can be transmitted onto the steel wire rope, the steep wire rope keeps certain tensioning force, and meanwhile rotation of the steel wire rope pulley is not influenced; and overall machining precision is high, mechanical efficiency is high, movement is accurate, components are easy to demount and replace, and the problem of steel wire rope jumping existing in most devices is solved.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a wire rope anti-loosening device. Background technique [0002] With the large-scale, high-speed and modernization of modern ships, the single-cable or through-cable replenishment system has gradually been unable to meet the actual needs. The single-rope dry cargo replenishment system is a replenishment system composed of a winch on the supply ship and a winch on the receiving ship through a pulley train. Its disadvantages are high requirements on sea conditions, low work efficiency, poor safety, and the receiving ship needs to be equipped with winches. The Tongsuo dry cargo supply system is improved on the basis of the single-rope supply system. It is a supply system composed of two winches on the supply ship and the pulley train on the receiving ship. Its disadvantages are high requirements on sea conditions and poor safety. Therefore, a high-line dry cargo supp...
