The invention belongs to the technical field of elevator maintenance, particularly relates to a safety protection device for elevator car roof maintenance. The following scheme is provided for solvingthe problems that most traditional elevator car roof protection devices are complex in structure, generally of an integrated structure, inconvenient to install and carry and capable of affecting maintenance operation. The safety protection device comprises a frame plate, hydraulic rods are vertically fixed to the four corners of the outer wall of the top of the frame plate through bolts, connecting rods are fixed to the ends of extending rods of the hydraulic rods through bolts, the outer wall of one end of each connecting rod is sleeved with a supporting barrel, and a same top plate is fixedto the outer walls of the tops of the supporting barrels through bolts. According to the safety protection device, electromagnets are arranged, so that the frame plate and a car roof are convenientlyadsorbed and connected; through the arrangement of the hydraulic rods, the connecting rods and the supporting barrels can be conveniently supported, and the device is unfolded; and through arrangement of the top plate, a good top rushing prevention effect can be achieved, and the safety of personnel is protected.
本发明属于电梯检修技术领域,尤其是一种用于电梯轿顶检修的安全保护装置,针对传统的电梯轿顶保护装置大多结构较为复杂,一般为一体式结构,其安装、携带较为不便,影响检修作业进行的问题,现提出以下方案,包括框板,所述框板的顶部外壁四角均通过螺栓竖直固定有液压杆,且液压杆的延伸杆端部通过螺栓固定有连接杆,所述连接杆的一端外壁套接有支撑筒体,且支撑筒体的顶部外壁通过螺栓固定有同一个顶板。本发明通过设置的电磁铁便于对框板以及轿顶进行吸附连接处理;通过设置的液压杆,便于将连接杆以及支撑筒体撑起,并将该装置进行展开;通过设置的顶板,能够起到良好的防冲顶效果,保护人员安全。
