The invention discloses a car roof guardrail capable of achieving folding and unfolding. The car roof guardrail comprises four guardrail monomers which are connected end to end to form a quadrilateral combined guardrail, and at least one guardrail monomer comprises a first monomer and a second monomer which are arranged oppositely, and a safety protection device, the guardrail monomer provided with the first monomer and the second monomer has a closed state and an open state; when the car roof guardrail is in the closed state, the first monomer is fixedly connected with the second monomer, and the safety protection device is electrically connected with a driving mechanism for controlling a car to rise and fall, so that the car does lifting motion; and when the car roof guardrail is in an open state, the first monomer and the second monomer are separated to keep a distance, and the car stops moving. According to the car roof guardrail capable of achieving folding and unfolding, through arrangement of the guardrail monomers which can be opened and closed, maintenance personnel can safely enter and exit from the horizontal space of the car roof, accidents due to movement of the maintenance personnel in the horizontal space of the car roof can be effectively avoided, and safety guarantee is provided.
本发明公开一种可折叠开合的轿顶护栏,其包括四个护栏单体,四个护栏单体首尾连接组成四边形组合护栏,至少一个护栏单体包括相对设置的第一单体与第二单体及安全保护装置,且具有第一单体与第二单体的护栏单体具有闭合状态和打开状态,当轿顶护栏处于闭合状态时,第一单体与第二单体固定连接,安全保护装置与控制轿厢升降的驱动机构电连接,以使轿厢做升降运动;当轿顶护栏处于打开状态时,第一单体与第二单体分离使两者之间保持间距,轿厢停止运动。本发明提供的可折叠开合的轿顶护栏,通过设置可打开和闭合的护栏单体,益于维保人员安全进出轿顶水平空间内,并可有效预防维保人员在轿顶的平空间内活动发生意外事故,提供安全保障。
