The invention discloses a pin inserting and pulling device and a crane, and relates to the technical field of pin inserting and pulling device.The pin inserting and pulling device is used for inserting or pulling out a pin shaft between an auxiliary arm of the crane and a main arm of the crane, the auxiliary arm is provided with a connecting plate, the connecting plate is provided with a first pin shaft hole, and the pin inserting and pulling device comprises the first pin shaft, a base and a driving component; the base is used for being installed on the main arm, the driving component is installed on the base, and an extending shaft of the driving component is connected with the first pin shaft and extends out or retracts back to drive the first pin shaft to be inserted into or pulled out of the first pin shaft hole. According to the pin inserting and pulling device, the first pin shaft is controlled to be inserted into or pulled out of the first pin shaft hole through the driving component, so that the pulling or inserting efficiency of the first pin shaft is greatly improved, the unfolding or folding efficiency of the fly jib is greatly improved, an operator does not need to manually pull out or insert the first pin shaft, and the labor intensity of the operator is also reduced.
本发明公开了一种插拔销装置及起重机,涉及插拔销装置技术领域,其中,插拔销装置用于插入或拔出起重机的副臂与起重机的主臂之间的销轴,副臂设置有连接板,连接板开设有第一销轴孔,插拔销装置包括第一销轴、底座和驱动部件,底座用于安装于主臂,驱动部件安装于底座,驱动部件的伸出轴与第一销轴连接,驱动部件的伸出轴伸出或缩回,以用于驱动第一销轴插入或拔出第一销轴孔。本插拔销装置中,通过驱动部件控制第一销轴插入或拔出第一销轴孔,大幅提高了第一销轴的拔出或插入的效率,从而大幅提高了副臂展开或收回的效率,并且不需要作业人员手动拔出或插入第一销轴,这样也降低了作业人员的劳动强度。
