我国目前产量最多的电动葫芦是CD_1型电动葫芦,该电动葫芦设有导绳器装置,其主要功能是保证卷筒上的钢丝绳顺卷筒绳槽排列而不产生乱绳现象;同时与限位器配合动作,保证起升行程终点的安全限位。但是,由于CD_1型电动葫芦导绳器存在某些缺陷,不能有效地克服乱绳现象。七十年代初,我们在试制CD_1型0.5吨电动葫芦时,发现乱绳现象较严重,空钩时必需挂上一重物才能不乱绳。在用户访问中,用户意见较大,希望改进导绳器的性能,故此行业内将改进导绳器列为攻关项目(本刊1985年第2期曾经报导过靖江起重机
The current output of our country is the largest electric hoist CD_1 electric hoist, the electric hoist is equipped with guide rope device, its main function is to ensure that the reel on the reel rope groove arranged without disorderly rope phenomenon; the same time with the limit With the action, to ensure that the lifting end of the safety limit. However, due to the CD_1 electric hoist rope has some shortcomings, can not effectively overcome the random rope phenomenon. In the early seventies, when we tried out the CD_1 0.5 ton electric hoist, we found that the phenomenon of random lashing was serious. In the user visit, the user has a larger opinion, hoping to improve the performance of the guide rope, so the industry will improve the guide rope as a research project (No. 2 of 1985 Jingjiang crane once reported
