我厂有0.5t、1t的CD_1型电动葫芦170余台.在使用过程中,遇到一个较为棘手的问题,就是厂房高度有限,当料桶升到卸料平台时,多数电动葫芦的吊钩顶部到卷筒底部的距离只剩100～150mm,而这个距离一般是上限位行程开关控制的最小距离,电动葫芦每次起重都要使行程开关动作,料桶才能到位.CD_1型电动葫芦限位动作是由导绳器拨动行程控制杆而顶动限位开关触头来完成的,它们之间为刚性接触,由于惯性作用再加上频繁使用,导绳器和限位开关经常被挤坏,十天半月甚至几天就需修理或更换.为此,我们将限位装置作了改进,即将原限位开关和行程控制杆拆掉,导绳器保留.在钢丝绳固定端上用螺栓、螺母固定一个行程开关,距卷筒底部约10Omm,行程开关触头朝下.在行程开关下方装一胶木
I plant 0.5t, 1t of CD_1 electric hoist more than 170. In the course of use, encountered a more difficult problem is the plant height is limited, when the bucket rose to the discharge platform, the majority of electric hoist hook The distance from the top to the bottom of the drum is only 100 ~ 150mm, and the distance is generally the minimum distance limit switch limit control, electric hoist each trip must make the trip switch action, buckets in place .CD_1 electric hoist limit Bit action by the guide rope toggle stroke control lever and move the limit switch contact to complete the rigid contact between them, due to inertia coupled with frequent use, the guide rope and limit switches are often crowded Bad, ten days and a half months or even days to be repaired or replaced.To this end, we will improve the stopper device, the original limit switch and the stroke control rod removed, the guide rope retainer.Rubber on the fixed end of the bolt , The nut fixed a travel switch, about 10Omm from the bottom of the reel, the travel switch contacts down .At the bottom of the travel switch installed a bakelite
