The anti-falling mechanism comprises a conveying platform, a connecting rod mechanism, an elastic mechanism, a limiting switch and a self-locking mechanism, the conveying platform is installed on a lifting belt, the connecting rod mechanism comprises a first connecting rod, a second connecting rod and two rockers, and the two ends of the first connecting rod and the two ends of the second connecting rod are rotationally connected through the rockers; the elastic mechanism is arranged between the conveying platform and the lifting belt, one end of the elastic mechanism is connected with the first connecting rod, the other end of the elastic mechanism is pressed through the lifting belt, the limiting switch is arranged on the second connecting rod, the self-locking mechanism is arranged on the conveying platform, and the conveying platform can be locked and fixed to a rack of the lifting conveying equipment through the self-locking mechanism. When the elastic mechanism is compressed, the self-locking mechanism is in an unlocking state and the lifting belt is broken, the elastic mechanism resets to drive the first connecting rod to move, the first connecting rod drives the second connecting rod to enable the limiting switch to retract, and the self-locking mechanism locks the conveying platform, so that the conveying platform is prevented from falling and being damaged, and the safety is improved.

    本发明公开一种防坠机构及升降运输设备,防坠机构包括输送平台、连杆机构、弹性机构、限位开关及自锁机构,输送平台安装在提升带上,连杆机构包括第一连杆、第二连杆及两个摇杆,第一连杆和第二连杆两端通过摇杆转动连接,弹性机构设置在输送平台和提升带之间,弹性机构一端与第一连杆连接,弹性机构另一端通过提升带压紧,限位开关设置在第二连杆上,自锁机构设置在输送平台上,自锁机构能将输送平台锁紧固定在升降运输设备的机架上,提升带工作时,弹性机构压缩,自锁机构处于解锁状态,提升带断裂时,弹性机构复位带动第一连杆移动,第一连杆带动第二连杆使限位开关缩回,自锁机构将输送平台锁紧,从而防止输送平台坠落损毁,提高了安全性。
