Electrically-driven steel wire rope anti-loosening device for offshore supply

Abstract

The invention discloses an electrically-driven steel wire rope anti-loosening device for offshore supply. The device comprises a base, a jack, a mounting cylinder, a telescopic mechanism, a follow-uppulley, a tension pulley block, a compensation pulley and a power pulley mechanism, the cylinder body and the jack are both installed on the base. The jack is positioned in the mounting cylinder; thebottom of the telescopic mechanism is installed on a top disc of the jack. The top of the telescopic mechanism is connected with a compensation pulley; the compensation pulley is located on the upperportion of an inner cavity of the installation cylinder, the follow-up pulley and the power sliding mechanism are arranged on the two opposite sides of the outer wall of the installation cylinder, thetension pulley block is arranged on one side of the follow-up pulley, and the tension pulley block is installed between the follow-up pulley and the compensation pulley. Non-hydraulic driving is achieved, the occupied space of the supply system on a real ship is reduced, the overall requirements of the system are met, and subsequent maintenance is more convenient.

Description

technical field [0001] The invention belongs to the technical field of ship replenishment at sea, and in particular relates to an anti-loosening device for electrically driven steel wire ropes for replenishment at sea. Background technique [0002] Replenishment at sea is a means of logistics support that must be adopted in modern naval warfare. as attached figure 1 As shown in Fig. 1, when carrying out horizontal replenishment during navigation, it is necessary to set up tension rigging between two ships sailing in parallel in the same direction (supply ship 1' and receiving ship 6'), and then carry out the replenishment operation through the cargo-carrying 4' trolley. The anti-loosening device plays an irreplaceable role in the horizontal replenishment operation during navigation. When the replenishment operation starts, the wire rope on the winch needs to be released with a certain tension to form a closed transmission loop (including the inner cable 2', the load-bearing...

AI Technical Summary

Problems solved by technology

This type of anti-loosening device does not have a tension compensation device, which cannot compensate for tension fluctuations in the system, and requires a separate hydraulic pump station, which has high requirements for installation space, oil, hydraulic pipelines, etc., and hydraulic maintenance is also very cumbersome and costly. Manpower and material resources

More importantly, the speed and load index requirements of electric sea compensation have been greatly improved, and the tension fluctuation will be more severe. The hydraulic drive anti-loosening device can no longer meet the needs of electric sea compensation, and a new anti-loosening device must be equipped
