Embodiment Construction

[0021] In this example, if figure 1 As shown, a warning safety ladder is composed of ladder beams 1 on both sides and several crosspieces 2 connected between the ladder beams 1 on both sides. 1 A spirit level with an included angle of 60°; a 60° included angle with the ladder beams 1 on both sides means that the level is 0° when the safety ladder is in use. In specific implementation, a pair of spirit levels can be set respectively at the positions of 1.3-1.5 meters from the bottom of the ladder beams 1 on both sides, such as figure 1 The left level 4a and the right level 4b in the middle are convenient to check the angle state of the level on either side. Such as figure 2 As shown, the structure of the spirit level is composed of a base 10 and a level tube 11 located inside the base 10. A liquid (such as alcohol) is encapsulated in the level tube 11, and a bubble 12 is left. When the bubble 12 is placed in the middle position, It shows that the spirit level 4 is in the ho...

Abstract

The invention discloses a warning safety ladder and its installation method. The warning safety ladder includes ladder beams on two sides and several crosspieces connecting the ladder beams on two sides. The warning safety ladder is characterized in that: level meters at a 60-degree included angle with the ladder beams on two sides are disposed at the lower parts of the ladder beams on two sides; warners are arranged on the upper parts of the ladder beams on two sides and are communicated with spring push switches on an upper crosspiece at the upper part of the ladder beams on two sides, and a trough type pedal covering the upper crosspiece is disposed on the spring push switches. The warning safety ladder provided by the invention can solve the problems that correct safety angle judgment cannot be achieved during safety ladder use and early warning is impossible when a limited climbing height is exceeded, completely eradicates operation staff's use of ladders against rules, reduces security risks, and ensures the personal safety of operating staff.

Description

technical field [0001] The invention relates to a tool for climbing a height, in particular to a safety ladder and an installation method thereof. Background technique [0002] Ladders are one of the most commonly used climbing tools for climbing operations. They are simple and convenient to use, but they also have certain potential safety hazards. For a long time, the climbing safety ladders used in substations have been greatly affected by human subjective factors during use, and they are often not used correctly and standardizedly, nor can they comply with the relevant provisions of the State Grid Corporation of Electricity Safety Work Regulations. For example, it is stipulated in the regulations that the safe angle between the safety ladder and the ground is 60°, but it is difficult to accurately grasp this angle with human judgment; when the operator exceeds the height limit during the climbing process, it is impossible to warn the operator of violations Behaviors may ...
