,具体涉及一种销轴取出装置。
技术介绍
矿山工程机械设备的大多结构均采用铰接销轴连接固定,例如采煤机各部件、掘进机结构件、综采工作面液压支架的四连杆、顶梁铰接等。尤其在煤矿生产单位,井下运输巷道、采掘工作面,设备需要不断进行搬迁解体、移动拆除、运输及更换零部件等过程,这就需要频繁拔出机械设备各部件连接销轴进行设备解体。解体设备的速度取决于各个连接销轴拔出的时间,由于工作环境潮湿粉尘等原因,连接销轴和销孔间隙小,再加上设备自重、挤压、锈蚀、受力不均等诸多因素,拔除销轴非常困难,严重影响工程进度。之前拔销轴是由工人拿锤子不断敲打销端或利用一根甩锤连接于销轴端头间隙进行震动操作,锤子和甩锤拔销是间断震动受力,效果不是太好,时常遇到拔不出或拔了4、5个小时才能拔出的情况,也不是非常确定一定能拔出,所以为了彻底解决拔销轴困难,急需改进拔取销轴思路及方法。
技术实现思路
为此,本技术实施例提供一种销轴取出装置,以解决现有技术中由于销轴难以取出而导致严重影响
