The invention discloses a safety rope ladder capable of automatically sealing a door. The safety rope ladder comprises two ladder poles, wherein the two ladder poles are connected and fixed through parallel ladder bars; each ladder pole comprises a main ladder pole and an assistant ladder pole; the top ends of the main ladder pole and the assistant ladder pole in a same main pole are connected through a ladder cross beam; a fixing platform is also arranged on each main ladder; the side wall of each fixing platform is provided with a triangle safety lever; one end of the lower part of each triangle safety lever is connected with the corresponding fixing platform through a positioning screw; each positioning screw is fixed on the side wall of the corresponding fixing platform, and the axial direction of each positioning screw is parallel to the axial direction of the corresponding ladder pole; a Z-shaped hanger plate is arranged under each fixing platform; a haulage cable is arranged under each Z-shaped hanger plate; each haulage cable is driven through a draft gear to open the corresponding triangle safety lever, and each triangle safety lever is closed through a reset spring. The safety rope ladder capable of automatically sealing the door is convenient, flexible, safe and reliable.
Description
technical field [0001] The invention belongs to the field of construction and maintenance of power system lines, and in particular relates to an automatic door-sealing safety soft ladder head. Background technique [0002] With the development of society, the scale of the city is increasing day by day, and the power consumption capacity is constantly increasing, so the faults of the line are increasing, so it is necessary to check and repair the transmission line frequently. Climb up the ladder for maintenance. However, the end of the traditional ladder hanging on the wire does not have a locking device. The ladder is simply hung on the cable. It may fall off during the climbing process, causing casualties in severe cases. ,There are security risks. Contents of the invention [0003] In order to solve the above problems, the present invention provides an automatic door-sealing safety ladder head, which can realize the locking between the soft ladder head and the cable, an...
