Single inspection well operation safety device with ladder stand
The invention provides a single inspection well operation safety device with a ladder stand, and relates to an inspection well operation safety device. A wide small frame and a narrow small frame arearranged on the rear portions of the two ends of a front frame respectively; the rear portion of the frame on one side is hinged to the front portion of the narrow small frame; the rear portion of theframe on the other side is hinged to the front portion of the wide small frame; one end of a protective stop lever (9) is hinged to the rear end of the frame on one side, and the other end of the protective stop lever (9) is connected with the rear end of the frame on the other side; a rotating pipe (13) is arranged at the upper end of the stretching telescopic ladder stand; and the two ends of the rotating pipe (13) are connected to shaft bases (37) arranged on the lower portion of the narrow small frame and the lower portion of the wide small frame respectively. Protection of a well mouth is formed through the front frame, the frame on one side, the frame on the other side and the protective stop lever, the telescopic ladder stand is small in occupied space and can be hidden in the frames in the conveying process, and conveying and using of maintenance and repair personnel are facilitated.
一种具有爬梯的单人窨井作业安全装置，涉及一种窨井作业安全装置，在前框架的两端后部分别设有一宽一窄的小框架，一侧框架后部铰接连接窄的小框架前部，另一侧框架后部铰接连接宽的小框架前部，防护挡杆（9）一端铰接连接一侧框架后端，防护挡杆（9）另一端连接另一侧框架的后端，伸展开伸缩爬梯的上端设有旋转管（13），所述旋转管（13）的两端分别连接在窄的小框架和宽的小框架下部分别设置的轴座（37）上；本发明利用前框架、一侧框架、另一侧框架和防护挡杆形成井口的防护，伸缩爬梯占用空间较小并在运送时可隐藏在框架内，方便了维护检修人员的运送和使用。
