The invention discloses marine hoisting rescue equipment, and relates to the technical field of hoisting. The problems of stability and safety are solved. The device specifically comprises a large arm fixed to a ship body through a supporting base, the inner wall of the large arm is slidably connected with two symmetrical sliding arms, one sliding arm is provided with a twisted rope pulley block, the top of the other sliding arm is slidably connected with a sliding base, and a winch is fixedly installed at the top of the sliding base. The balancing weight is arranged, due to the characteristics that the balancing weight and the heavy object are oppositely arranged relative to the supporting base, and the matching torque is equal to the product of force and the force arm, the torque of the heavy object to the supporting base can be balanced, the sliding base is arranged to be in an elastic supporting mode, and the balancing weight and the sliding base are linked through the lever; therefore, the middle balancing weight can adaptively adjust the force applying arm of the balancing weight on the large arm according to the specific lifting weight, the reliability of moment balance can be guaranteed, the stability of a ship body is improved, and the safety of the ship body is also improved.
本发明公开了一种船用起重救援设备,涉及起重技术领域;为了解决稳定性和安全性问题;具体包括通过支撑座固定于船身的大臂,所述大臂的内壁滑动连接有两个相互对称的滑动臂,其中一个所述滑动臂设置有绞绳滑轮组,另一个所述滑动臂的顶部滑动连接有滑座,滑座的顶部固定安装有卷扬机。本发明通过设置配重块,由于配重块与重物相对支撑座对置,配合力矩等于力与力臂乘积的特性,所以其可平衡重物对支撑座的扭矩,并且通过将滑座设置为弹性支撑,且通过杠杆将配重块与滑座联动,从而使得其中时配重块能根据起重的具体重量自适应调节配重块对大臂的施力力臂,从而可保证力矩平衡的可靠性,增加船身稳定性也增加其中安全性。
