The buffering device for the crane comprises a buffering frame and a hook, a sliding rod is slidably sleeved with a supporting plate, the side, located below the supporting plate, of the outer wall of the sliding rod is sleeved with a telescopic spring, and a connecting rod penetrating through the buffering frame is fixedly installed at the center of the lower surface of the supporting plate; a hook is fixedly installed at the end, located on the outer side of the buffering frame, of the connecting rod. The hook is connected with the supporting plate through the connecting rod, when a heavy object is hoisted, the heavy object is hooked through the hook, then hoisting equipment hoists the heavy object upwards through the buffering frame, in the hoisting process, the heavy object drives the supporting plate to slide downwards along the sliding rod through the connecting rod, the supporting plate extrudes the telescopic spring, and through the elastic force of the telescopic spring, the heavy object is hoisted. The impact force generated during hoisting is eliminated, rigid collision of hoisting equipment is avoided, the hoisting equipment is protected, and the hoisting stability is improved.
本发明公开了一种起重机用缓冲装置,包括缓冲框架和挂钩,所述滑杆上滑动套接有支撑板,所述滑杆外壁位于所述支撑板下方的一侧套接有伸缩弹簧,所述支撑板下表面的中心处固定安装有贯穿所述缓冲框架的连接杆,所述连接杆位于所述缓冲框架外侧的一端固定安装有挂钩;本发明通过连接杆将挂钩与支撑板连接,在起吊重物时,通过挂钩勾住重物,然后起吊设备通过缓冲框架向上起吊重物,在起吊的过程中,重物通过连接杆带动支撑板沿着滑杆向下滑动,使得支撑板对伸缩弹簧产生挤压,通过伸缩弹簧的弹力,将起吊时产生的冲击力消除,避免起吊设备产生刚性碰撞,对起吊设备起到保护作用,提高了起吊的稳定性。
