Embodiment Construction
[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0016] Such as figure 1 As shown, the preferred embodiment of the present invention includes: safety buckle 1, first adjustment rope 21, second adjustment rope 22, ladder, pole 33, rotating shaft seat 4, rotating shaft 41, joystick 42, positioning structure, first fixed pulley 61, the second fixed pulley 62.
[0017] Specifically, the safety buckle 1 is used to hang on the upper steel rod arm of the steel pole. The safety buckle is a tool commonly used in the field of electric power construction. Large and needs to be able to nest on a steel pole arm. Of course, other easy-to-hang devices can also be used instead. The upper end of the first adjusting rope 21 is fixed on the safety buckle 1 ; the upper end of the second adjusting rope 22 is also fixed on the safety buckle 1 . The length of climbing ladder should not be too long, it...

The invention provide a special ladder for construction on steel bar arms, which comprises a safety buckle for being hung on an upper level steel bar arm of a steel bar; a first adjusting rope with an upper end fixed on the safety buckle; a second adjusting rope with an upper end fixed on the safety buckle; a crawling ladder which comprises a first vertical beam, a second vertical beam and a crossbeam and is used for a power worker to stand; a support rod connected between upper ends of the first vertical beam and the second vertical beam; a rotating shaft which is rotatably disposed on the support rod, wherein the second ends of the first adjusting rope and the second adjusting rope respectively pass through the upper ends of the first vertical beam and the second vertical beam and are fixed on the rotating shaft, and when the rotating shaft rotates, the first adjusting rope and the second adjusting rope wind the rotating shaft simultaneously or unwind from the rotating shaft simultaneously; a joystick with a first end connected to the rotating shaft for controlling the rotation of the rotating shaft; and a positioning structure disposed at the second end of the joystick for stopping the rotation of the rotating shaft. The special ladder of the invention has the advantages of simple application, adjustable height, safety, reliability, and the like.
Description
technical field [0001] The invention relates to an auxiliary construction equipment for electric power equipment, in particular to a special ladder for construction on a steel rod arm. Background technique [0002] For high-voltage and ultra-high-voltage power lines, such as 35KV lines, steel pole conductor erection operations during construction, such as installing fittings, insulators and suspension conductors on steel pole iron towers, lapping bow wires, etc., need to build a sand pole on the steel pole The standing platform allows the staff to work on the steel pole. The construction of the standing platform is not only time-consuming, but also difficult to work due to the angle of the work, and the safety factor is very low. Contents of the invention [0003] The purpose of the present invention is to provide a special ladder for construction on a steel pole arm to solve the problems of time-consuming and unsafe construction of a station platform on a steel pole exist...
