The invention discloses an automatic folding type car top guardrail and an operation method using the same. The automatic folding type car top guardrail is used for protecting workers working on the top face of an elevator car. The automatic folding type car roof guardrail comprises a guardrail part, a transmission part, a driving part and control parts, servo motors of the control parts drive a rotating shaft of the transmission part to rotate in the axial direction through gear transmission, so that a guardrail body fixed to the rotating shaft rotates in the axial direction, and the moving angle of the guardrail body is limited by switches of the two control parts; and when the guardrail body touches the switch, the rotation automatically stops. According to the automatic folding type car top guardrail, folding or unfolding of the automatic folding type car top guardrail can be achieved only by sending commands twice through an external controller in the whole process, the automation degree is high, the control switch serves as a limiting device at the same time, and structural damage caused by the too large movement range of the guardrail body is avoided.

    本发明公开了一种自动折叠式轿顶护栏与使用本机构的操作方法,用于保护在电梯轿顶面作业的工人。自动折叠式轿顶护栏包括护栏部、传动部、驱动部和控制部,控制部的伺服电机通过齿轮传动带动传动部的旋转轴绕轴向旋转,从而使固定在旋转轴上护栏本体绕轴向旋转,护栏本体被两个控制部的开关限位其活动角度,且当护栏本体触碰到开关时旋转便自动停止。本发明全程仅需通过外部控制器发送两次命令便可实现自动折叠式轿顶护栏的折叠或展开,自动化程度较高,且控制开关同时作为限位装置的存在,也避免了护栏本体活动幅度过大导致的结构损坏。
