Problems solved by technology
like figure 1 As shown, the high outcropping ladders of transmission towers in the prior art are mainly made of pre-embedded iron parts, which are then welded on site or pasted with adhesives on site. Many, and high-altitude welding is difficult, or the durability of the adhesive is poor, and the connection strength is low; and there is no corresponding safety measure against falling

The invention discloses a safe ladder stand used for the high outcrop foundation of a power transmission iron tower. The safe ladder stand comprises a left vertical connecting rod, a right vertical connecting rod and a safe protection cage construction member, wherein a stepping plate is arranged between the left vertical connecting rod and the right vertical connecting rod; the left vertical connecting rod is fixedly connected with a left embedding steel sleeve on the left end of an embedding steel sleeve connecting piece through a horizontal left connecting element; the right vertical connecting rod is connected with a right embedding steel sleeve on the right end of an embedding steel sleeve connecting piece through a horizontal right connecting element the safe protection cage construction member comprises at least one protection cage vertical steel plate and at least two protection cage horizontal annular steel plates; each protection cage horizontal annular steel plate is arranged at equal intervals from top to bottom. The safe ladder stand has the advantages of small construction difficulty, short days for construction, low construction cost and good economic benefit and social benefit and can be widely applied to various high outcrop foundations, on which the ladder stand needs to be installed, of the power transmission iron tower.
Description
technical field [0001] The invention relates to a climbing ladder, in particular to a safety climbing ladder used for high outcropping foundations of power transmission towers. 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 flood control requirements of the towers near the river, the foundation outcrop will generally be relatively high. According to the relevant requirements of the transmission line design, in order to meet the construction of transmission towers And the needs of later inspection, when the top surface of the foundation column of the transmission tower is higher than the ground (5m and above), not only the foundation ladder needs to be installed, but also safety measures to prevent falling should be taken. Such as figure 1 As shown, the high outcropping ladders of transmission towers in the prior art are mainly made of pre-embe...
