[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. Elevator maintenance is a maintenance work that is regularly maintained by professionals to promptly discover and eliminate potential safety hazards of elevators and prevent elevators from running with problems.

[0003] During elevator maintenance work, when entering the pit to work, if the door on the first floor is to be open, warning signs must be placed at the hall door or someone must be on guard, and effective measures must be taken to prevent others from falling into the pit, thereby achieving a safety protection effect.

[0043] When in use, the pipe frames 1 are placed adjacent to each other, and the connecting piece 18 fixed with the threaded column 19 is placed on the top of the adjacent connecting ear 17, so that the threaded column 19 passes through the connecting ear 17, and the bottom connecting piece 18 is placed accordingly and locked by the hand nut 20. In this process, the rubber gasket 21 is installed between the connecting piece 18 and the connecting ear 17, so that the damping hinge between the adjacent pipe frames 1 is made, and the pipe frames 1 can be folded with each other for carrying. The pipe frames 1 are used to unfold each other through the cooperation of the connecting ears 17 and the connecting piece 18 and form a mutually inclined setting, so as to protect the hall door during elevator maintenance. At this time, the first hand-tightening bolt 10 and the second hand-tightening bolt 13 are loosened, and the fixation of the slider 4 and the extension rod 7 is loosened. At this time, the second cross tube 8 can be lifted upward, and then locked by the second hand-tightening bolt 13, and the slider 4 is controlled to slide on the slide rail 3, so that the curtain 9 is tightened and locked by the first hand-tightening bolt 10, thereby forming a higher safety protection.
