电动双梁行车是一般工厂中普遍采用的起重设备。在日常生产中,我们对其部分结构进行了改装,以达到使用方便、安全性好以及降低噪声的目的。经过几年使用,证明这些改革是行之有效的。小车供电部分原来行车小车供电部分是用角铁作导电架。这种供电方法有以下缺点:1)因接触不良等毛病,容易发生故障;2)由于导线裸露,安全性差;3)维护保养麻烦。现改用水龙带式,导线穿在水龙带内,水龙带由滑轮悬吊在钢丝绳上,钢丝绳固定在两端的支架上(图1)。活动部分是采用机械活接头(图2)。
Electric double beam drive is commonly used in general factory lifting equipment. In daily production, we have modified some of its structures to achieve ease of use, safety and noise reduction. After several years of use, these reforms proved to be effective. Part of the original car battery car power supply is part of the angle for the conductive frame. This power supply method has the following disadvantages: 1) due to poor contact and other problems, prone to failure; 2) due to bare wires, poor safety; 3) maintenance trouble. Now use the hose type, the wire worn in the hose, hose suspended by the pulley on the wire rope, rope fixed at both ends of the bracket (Figure 1). The active part is a mechanical union (Figure 2).
