楼房施工中,井字架或外用电梯是最常用的设备之一。但在使用中,吊篮因超载而坠落的事故时有发生,直接威胁施工人员的安全。为消除这一不安全因素,我们针对原有各种断绳保护器结构中存在的缺陷加以改进,研制出了弹簧销式断绳保护器。这种保护器具有结构简单,制作容易,安装方便,可靠性强等特点。它的工作原理是:当门吊钢丝绳折断时,由于弹簧所受压力消失,
In the construction of a building, a derrick or external elevator is one of the most commonly used equipment. However, in use, accidents that fall due to overloading of the hanging basket occur from time to time, which directly threaten the safety of the construction personnel. In order to eliminate this unsafe factor, we improved the existing defects in the various types of broken rope protector structure and developed a spring-pin broken rope protector. The protector has the advantages of simple structure, easy manufacture, convenient installation and strong reliability. Its working principle is: When the door hanger wire rope is broken, the pressure on the spring disappears.
