DB型井架吊篮断绳保安器是建筑井架施工中一种重要的安全保护设备,在各种钢管型井架和简易型货梯的吊篮机构上已广泛应用。一、保安器的运动原理整个装置如图1(二件),分别对称地安装在吊篮两侧立柱上,滑销轴在副钢丝绳牵引下通过定滑轮改变牵引方向同吊篮起吊钢丝绳联结。井架在正常工况下,滑销轴受副钢丝绳的拉力,弹簧被压缩,滑轴销全部缩进套筒内,此时吊篮升降均不受阻碍,当起吊钢丝绳断损或放松时,副钢丝绳对滑销轴的拉力消失,滑销轴在弹簧的作用下,伸出
DB-type derrick basket broken rope safety device is an important safety protection device in the construction of the construction of derricks. It has been widely used in various steel pipe derricks and simple cargo elevators. First, the movement of the security device The entire device shown in Figure 1 (two), respectively symmetrically installed on the two sides of the basket, the sliding pin shaft under the traction of the deputy wire rope through the fixed pulley to change the traction direction with the basket lifting wire rope connection. The derrick under normal working conditions, the sliding pin shaft by the deputy wire rope tension, the spring is compressed, the sliding shaft pin all retracted into the sleeve, this time the lifting basket are unimpeded, when the lifting wire rope breaks or relax, vice The pulling force of the wire rope on the slide pin disappears, and the slide pin shaft protrudes under the action of the spring
