Discontinuous friction damper and using method thereof
The invention discloses a discontinuous friction damper and a using method thereof, and belongs to the technical field of friction dampers, the discontinuous friction damper comprises a damper pull rod, a pull rod groove, a limiting hole, a damper shell, a damper sleeve, a pin shaft hole, a connecting piece, a fixing bolt, a pressing bolt, a disc spring, a guide bolt, a pressing block and a friction block, the friction damper provided by the invention can bear large stroke and large tonnage, when the tower crane faces a sudden unloading working condition, the damper initially operates to provide damping force, buffer the upwarp impact force of the cantilever crane, and cancels the damping force after operating for a certain stroke, so that the cantilever crane is convenient to upwarp and quickly fall off a balancing weight at the tail part of the balance arm, and the balance weight is quickly released after the falling off of the balancing weight is completed. The friction damper provides damping force and provides certain resistance for the cantilever crane to continuously turn over under the action of inertia force, so that upwarp displacement of the cantilever crane is reduced, and the risk that the cantilever crane overturns under the action of the inertia force to cause falling of the cantilever crane is prevented.
本发明公开了一种非连续式摩擦阻尼器及其使用方法，属于摩擦阻尼器技术领域，包括阻尼器拉杆，拉杆凹槽，限位孔，阻尼器壳，阻尼器套，销轴孔，连接件，固定螺栓，压紧螺栓，碟簧，导向螺栓，压块，摩擦块，本发明提供的摩擦阻尼器可承受大行程和大吨位，当塔机面对突然卸载工况时，阻尼器初始运行提供阻尼力，缓冲臂架上翘冲击力，运行一定行程后取消阻尼力，便于臂架上翘快速脱落平衡臂尾部平衡重，平衡重脱落完成后，摩擦阻尼器提供阻尼力，为臂架在惯性力的作用下继续翻转提供一定阻力，从而减小臂架上翘位移，防止臂架在惯性力的作用下过翻转从而引发臂架脱落的危险。
