The invention relates to the technical field of elevator protection, in particular to an elevator car roof maintenance safety protection device. In order to solve the problem that a circle of yellow isolation guardrails are arranged on three sides, far away from a landing door, of a car roof of an existing car roof safety protection device, and workers cannot be completely protected, the following scheme is provided, the car roof safety protection device comprises a supporting plate fixedly mounted at the top end of a car, and electric hydraulic rods which are symmetrically distributed are fixedly mounted at the top end of the supporting plate; the telescopic ends of the electric hydraulic rods face upwards and penetrate through the supporting plate in a sliding mode, a frame is fixedly installed between the top ends of the two electric hydraulic rods, and a foldable protection mechanism used for protecting the periphery of the lift car is arranged below the frame. According to the elevator, the frame is arranged to move upwards, when the frame drives the multi-stage telescopic rods to extend, the telescopic pipes drive the first guardrails to move upwards in sequence, the four sets of first guardrails on the periphery of the elevator car surround a worker, and all-around protection is conducted on the periphery of the worker.

    本发明涉及电梯防护技术领域,具体为一种电梯轿顶检修安全保护装置。针对现有的轿顶安全保护装置是在轿顶远离厅门的三侧设有一圈黄色的隔离护栏,不能完全保护工作人员的问题,现提出如下方案,其包括固定安装于轿厢顶端的支撑板,所述支撑板顶端固定安装有呈对称分布的电动液压杆,所述电动液压杆的伸缩端向上且滑动贯穿支撑板,两个所述电动液压杆顶端之间固定安装有框架,所述框架下方设有用于轿厢四周进行保护且可折叠式的防护机构。本发明通过设置框架向上移动,框架带动多级伸缩杆伸长时,伸缩管带动多个第一护栏依次向上移动,轿厢四周的四组第一护栏将工作人员围住,对工作人员的四周进行全方位的防护。
