The invention discloses a marine winch brake device, which relates to the technical field of winches, and comprises an outer shell, a movable shell, a brake mechanism, a pinion, a bull gear, a multi-stage buffer mechanism, a locking mechanism, a clamping mechanism and a connecting shaft, the piston is pushed through the oil cylinder, power is transmitted through hydraulic oil, the brake block is driven to brake the brake disc, primary braking of the winch main shaft is achieved, and the braking mode is efficient and reliable; the wear-resistant anti-skid layers are arranged on the opposite faces of the brake blocks, friction force is effectively increased, the braking effect is improved, and the stability of the braking process is guaranteed; the tooth grooves in the outer circle face of the movable shell are matched with the movable clamping teeth, when the braking resistance is increased, the movable clamping teeth and the tooth grooves are indirectly separated for braking, and the braking performance is further optimized; the large gear is used for driving the multi-stage buffering mechanism to work, oil in the oil storage cavity is pumped into the buffering oil cavity through the hydraulic pump for buffering and energy absorption, winch damage caused by braking is avoided, and the service life of the winch is prolonged.
本发明公开了一种船用绞盘刹车装置,涉及绞盘技术领域,包括外壳体、活动壳体、刹车机构、小齿轮、大齿轮、多级缓冲机构、锁紧机构、卡紧机构和连接轴;本发明中通过油缸推动活塞,利用液压油传递动力,带动刹车块对刹车盘进行制动,实现对绞盘主轴的初步制动,制动方式高效且可靠;本发明在刹车块相对面上设有耐磨防滑层,有效增大摩擦力,提升制动效果,保障制动过程的稳定性;通过活动壳体外圆面的齿槽与活动卡齿的配合,在制动阻力增加时,活动卡齿与齿槽间接性脱离进行制动,进一步优化制动性能;本发明利用大齿轮带动多级缓冲机构工作,通过液压泵将储油腔中的油泵入缓冲油腔进行缓冲和能量吸收,避免刹死造成绞盘损坏,延长绞盘使用寿命。
