A climbing ladder for an iron tower

Abstract

The invention relates to a climbing ladder for an iron tower, which comprises two upright beams and a cross beam, one side of the upright beams is fixedly connected with a plurality of supporting columns, one side of each upright beam is also fixedly connected with upright columns, and the upright columns are also provided with sliding sleeves, A sliding hole is vertically opened in the middle of the sliding sleeve, a sliding groove is also opened on one side of the sliding sleeve, a tooth groove is opened on one side of the column, a storage slot is opened on one side of the sliding sleeve, and a tooth block is slidingly connected in the storage slot. , a push spring is also fixedly connected to the first storage slot; a storage slot is opened on the side of the sliding sleeve corresponding to the chute, and a rotating column is connected to the rotation in the storage slot, and a swing plate is fixedly connected to one side of each rotation column. The side is fixed with a torsion spring, the side of the sliding sleeve corresponding to the rotating column is provided with a spline groove, the sliding sleeve is connected with a spline shaft, the sliding sleeve is connected with a sliding column, and the sliding column extends to one end in the sliding sleeve A connecting column is hinged with the end of the spline shaft away from the spline groove; the lower side of the sliding sleeve is also fixedly connected with a connecting ring. The invention has the effect of providing protection against falling for workers when they use the climbing ladder to work at high altitudes.

Description

technical field [0001] The invention relates to the technical field of iron tower equipment, in particular to a climbing ladder for an iron tower. Background technique [0002] In recent years, with the rapid development of the national grid construction, transmission towers have spread all over the country. According to the relevant requirements of transmission line design, in order to meet the needs of transmission tower construction and later inspection, when the top of the transmission tower foundation column is higher than the ground (5m and above), it is necessary to install a basic ladder for workers to maintain. [0003] The existing reference application announcement number is: CN110593749A Chinese invention patent, which discloses a new type of power steel pipe iron tower climbing ladder structure, including ladder frame steel pipes and climbing nails, and the front sides of the upper end and lower end of the ladder frame steel pipes are welded. The ear plate, the...
