The invention relates to the technical field of crane buffering, starting and stopping, and discloses a device capable of achieving decelerating, buffering and starting and stopping during crane operation. The device comprises a fixed disc, mounting grooves are formed in the inner wall of the fixed disc, buffering, starting and stopping blocks are movably mounted in the mounting grooves, rotatingdiscs are movably mounted in the fixed disc, clamping teeth are fixedly mounted on the outer walls of the rotating discs, cams are movably mounted in the clamping teeth, and ejector rods are movably mounted at the tops of the cams. A lifting device drives the rotating discs to rotate, after the clamping teeth on the rotating discs make contact with the buffering, starting and stopping blocks, thelifting speed of a crane can be decreased, the cams in the clamping teeth rotate to drive the ejector rods to move upwards, the buffering, starting and stopping blocks deflect, springs above the buffering, starting and stopping blocks contract, the clamping teeth can leave the buffering, starting and stopping blocks, the lifting device can continue to drive the rotating discs to continue to rotate, and the effect of buffering and decelerating the crane is achieved.

    本发明涉及起重机缓冲启停技术领域,且公开了一种起重机运行中减速缓冲且能够进行启停的装置,包括固定圆盘,所述固定圆盘的内壁开设有安置槽,所述安置槽的内部活动安装有缓冲启停块,所述固定圆盘的内部活动安装有旋转圆盘,所述旋转圆盘的外壁固定安装有卡齿,所述卡齿的内部活动安装有凸轮,所述凸轮的顶部活动安装有顶杆。通过升降装置带动旋转圆盘转动,旋转圆盘上的卡齿会与缓冲启停块接触后,起重机升降速度会减缓,卡齿内部的凸轮转动带动顶杆向上运动,将缓冲启停块偏转,缓冲启停块上方的弹簧收缩,卡齿将会离开缓冲启停块,升降装置将会继续带动旋转圆盘继续转动,达到了给予起重机进行缓冲减速的效果。
