Embodiment Construction

[0012] Such as Figure 1-4 As shown, hooks 7 are installed at the upper and lower ends of the upright main pole 1, and the horizontal step bar 2 is hinged on the upright main bar 1 through the rotating shaft 3, and the position corresponding to the horizontal step bar in the upright main bar is matched with the width of the horizontal step bar. Longer pedal bar groove 4. The horizontal step bar 2 is vertically folded and placed in the step bar groove. The horizontal step bar rotating shaft 3 separates points, the longer side is the long arm stepping end 21, and the shorter side is the short arm fixed end 22. The pedal groove described above is provided with two notches on the left and right sides of the upright main pole 1, which are respectively the long arm notch 5 corresponding to the long arm pedal end 21 and the short arm notch corresponding to the short arm fixed end 22 6. Wherein the notch of the long arm is above the rotating shaft, and the notch of the short arm is ...

Abstract

The invention provides a centipede-type ladder. The centipede-type ladder comprises an upright main lever, wherein horizontal foot levers are installed on the upright main lever and are hinged on the upright main lever via axes of rotation; a foot lever groove is formed in the upright main lever; a long arm notch and a short arm notch are formed in the foot lever groove and are respectively formed in the left and right sides of the upright main lever; when the centipede-type ladder is used, the horizontal foot levers rotate at 90 degrees to extend out of the foot lever groove to be in a horizontal state. The centipede-type ladder has the beneficial effects that the foot lever groove is formed in the upright main lever of the centipede-type ladder, and the horizontal foot levers are stored in the groove at ordinary times and are opened during operation, thus greatly reducing the transport volume and the space usage; moreover, the centipede-type ladder is convenient for a single person to move and erect; meanwhile, the long arm notch and the short arm notch are formed in the two sides of the upright main lever respectively, thus ensuring the movable horizontal foot levers to be stable and safe and not to slide or deviate during operation.

Description

technical field [0001] The invention relates to a power transmission line operation tool, in particular to a centipede ladder which is convenient and mobile. Background technique [0002] The centipede ladder is a working tool widely used in the installation, inspection and maintenance of power grid transmission lines. And the existing centipede ladder takes up a lot of space in transportation because the pedals protruding from both ends are not easy to carry. The components in the installation must be set up very carefully, which will result in time-consuming and laborious operations, affecting work efficiency and progress. Contents of the invention [0003] Aiming at the problem of inconvenient carrying and erecting of centipede ladders in the prior art, the present invention provides a centipede ladder. [0004] A centipede ladder of the present invention comprises an upright main rod, on which a horizontal stepping rod is installed, and is characterized in that: the...
