The invention relates to a heavy hook head multi-rope winding system, a crane and a hoisting method, the winding system comprises n deepwater hook movable pulley blocks and deepwater hooks, the deepwater hook movable pulley blocks are uniformly distributed on the deepwater hooks, and n is a positive integer not less than 2; n sets of main hook fixed pulley blocks, n sets of auxiliary hook fixed pulley blocks, n sets of main hook winches and n sets of auxiliary hook winches are arranged; the number of the main hook ropes and the number of the auxiliary hook ropes are both n. The control system controls the winding and unwinding speed and torque of the n sets of main hook winches and the n sets of auxiliary hook winches to synchronously operate the n lifting ropes at the same time, and balance control and lifting operation of the deepwater hook are achieved. According to the crane and the hoisting method, deepwater heavy hoisting operation is achieved based on the winding system. The problems of'twisting 'of large-tonnage hoisting deepwater steel wire ropes, function diversification of the crane and the like are solved, the requirements of deepwater heavy hoisting operation are met, and the investment cost of crane equipment is reduced.

    本发明涉及一种重型钩头多绳缠绕系统、起重机及吊装方法,所述缠绕系统包含深水钩动滑轮组及深水钩,所述深水钩动滑轮组有n套且均布设置在深水钩上,n为不小于2的正整数;所述主钩定滑轮组、副钩定滑轮组、主钩绞车、副钩绞车均有n套;所述主钩绳和副钩绳均为n条;所述控制系统通过控制n套主钩绞车和副钩绞车的收放卷速度和扭矩,对n条吊绳同时同步操作,实现深水钩的平衡控制及吊重作业;所述起重机及吊装方法基于所述缠绕系统实现深水重型吊装作业。本发明解决了大吨位吊重深水钢丝绳“打绞”及起重机功能多元化等问题,满足了深水重型吊重作业需求,减少起重机设备投资成本。
