Embodiment
[0015] Embodiment: The present invention is all made of aluminum alloy material, light in weight, and the ladder is freely connected and assembled in sections, and the required height and length can be adjusted. It is easy to carry and transport when unfolded, and it is safe and stable to climb when unfolded. The hook can be connected to any section of the ladder, and the connecting pipe can also be connected to any section of the ladder. All the ladders are uniformly configured. The hanging board is divided into two pieces, which can be hooked no matter whether the foot nail is on the left or the right side, and the original ladder steel pipe is clamped in the middle, and the connecting plate in the middle of the two hanging boards is just tangent to the original ladder steel pipe. The vertical gravity makes the entire auxiliary climbing tool firmly attached to the steel pipe tower without any shaking.

An auxiliary climbing tool of a steel pipe tower of an electric transmission line comprises a ladder stand pipe, installed on the side wall and according to the needed size, of drill holes; shackle seats are inserted into the drill holes in a welded and positioning mode, shackles capable of being vertically bent and with circular arc grooves are installed on the shackle seats through bolts, and meanwhile, positioning devices being composed of steel balls, springs and spring seats are further installed on the shackle seats; when the shackles are unbent, the steel balls of the positioning devices are exactly clamped into the circular arc grooves corresponding to the shackles, and unbent positioning is achieved; when the shackles are upwards bent, the steel balls of the positioning devices are also exactly clamped into the circular arc grooves, and bent positioning is achieved; and the drill holes are formed in the ladder stand pipe in a left-right symmetrical and vertically-staggered mode, hooks capable of directly hanging the ladder stand pipe on ladder stand shackles of an original steel pipe tower are fixed to the upper end of the ladder stand pipe through bolts, and a connecting pipe capable of connecting the multiple ladder stand pipes so as to form the assembly type auxiliary climbing tool is installed at the lower end of the ladder stand pipe.
Description
technical field [0001] The invention relates to an auxiliary climbing tool for a steel pipe tower of a transmission line, which is a special auxiliary tool used for climbing the steel pipe tower of a transmission line in the maintenance work of electric power. Background technique [0002] Steel pipe towers of transmission lines are generally equipped with steel pipe ladders for inspection and maintenance on the towers. In order to prevent non-operating personnel from climbing, causing electric shock hazards and accidents, the lower (end) end of the steel pipe tower ladders is 3 meters above the ground. Usually operators need to climb with the help of long ladders, and using bamboo ladders to climb has potential safety hazards, which does not meet the requirements of regulations, and the ladders are tall and difficult to transport, which is not conducive to carrying. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of ...
