卷扬筒是起重机起升机构的重要部件。在日常的检修中,如更换起升机构中的易损件,势必涉及到卷扬筒的拆装,由于目前桥式起重机卷扬简装配结构设计的特点,使卷扬筒的安装和拆卸十分困难,我厂起重机检修工人在长期的经验积累中发现,只要在安装结构上稍加改进,增设一个轴承挡圈,便会使卷扬筒的拆装变得十分简便,拆装时间可从原来4小时缩短到1时左右。 Winch drum crane lifting mechanism is an important component. In the daily maintenance, such as replacement of wearing parts in the lifting mechanism, it is bound to involve the winch drum disassembly, due to the current winch hoist Jane assembly structure design features, so winch cylinder installation and removal of a very Difficulties, I plant crane overhaul workers in the long-term accumulation of experience found that as long as the installation structure of a slight improvement, the addition of a bearing ring, it will make winding drum disassembly has become very easy, dismantling time from the original 4 hours shortened to about 1 o’clock.
