The invention relates to a tensioning device and a tensioning method, and belongs to the technical field of engineering machinery rope coiling. The tensioning device comprises a rack assembly, at least two tensioning discs, a rotating shaft and a brake damping piece. The tensioning disc is used for winding or unwinding a rope, a rotating shaft is arranged in the brake shell, and the brake damping piece provides damping to tension the rope in the no-load state or the state smaller than a set load value and cancels damping to avoid the load in the heavy-load state or the state larger than the set load value. The invention further provides a hoisting machine comprising the tensioning device and a tensioning method. Torque energy is released through cooperation of the coil spring and the overrun clutch to assist no-load hook falling and rope releasing, and the operation efficiency is improved; through the cooperative use of the friction plate assembly, the piston and the brake oil port, the tensioning force is automatically adjusted, the problems of rope deformation and wire breakage are avoided, and the device has the advantages that the rope winding quality is improved, the tensioning force is automatically adjusted, the maintenance cost is reduced, the operation efficiency is improved, and the structural stability is enhanced.
本发明涉及一种张紧装置及张紧方法,属于工程机械盘绳技术领域。张紧装置包括机架组件、至少两个张紧盘、转动轴和制动阻尼件。张紧盘用于缠绕或放出绳缆,制动壳体内设置转动轴,制动阻尼件在空载或小于设定载荷值时提供阻尼以张紧绳缆,而在重载或大于设定载荷值时取消阻尼以避免负载。本发明还提供了包括所述张紧装置的起重机械和张紧方法。本发明通过卷簧和超越离合器配合实现释放扭矩能量辅助空载落钩放绳,提高作业效率;通过摩擦片总成和活塞及制动油口的配合使用,自动调整张紧力,避免绳缆变形和断丝问题,具有提高绳缆缠绕质量、自动调节张紧力、降低维护成本、提高作业效率以及增强结构稳定性的优点。
