AI Technical Summary

Technical Problem

The existing ladders lack safety design during arc-shaped roof construction, cannot be safely connected to the roof spine, and are not convenient for lateral movement, resulting in safety hazards and inconvenient operation of construction personnel.

Method used

A arc-shaped roof safety ladder is designed, adopting a combined structure of galvanized steel pipes and limiting booms. The limiting booms are connected to galvanized steel pipes and are equipped with fixed rubber wheels, which can be safely connected to the arc-shaped roof spine of the steel structure and move sideways during construction.

Benefits of technology

The safe connection between the ladder and the roof spine is achieved, avoiding the risk of ladder falling or skewing, making it easier for construction personnel to move horizontally during construction, and improving construction safety and convenience.

Abstract

The utility model discloses an arc-shaped roof safety crawling ladder which comprises galvanized steel pipes and cross rods which are installed on arc-shaped roof ridge beams and limiting arm rods, the ends of the limiting arm rods are connected with the ends of the corresponding galvanized steel pipes, fixed rubber wheels are arranged on the limiting arm rods and the galvanized steel pipes, fixed beams are arranged on the surfaces of the galvanized steel pipes, and the fixed beams are connected with the limiting arm rods. A fixed column, a lifting arm and a limiting piece are arranged on the fixed beam, an inclined supporting arm is arranged at the end of the lifting arm, a blocking piece penetrates through the inclined supporting arm and comprises a first connecting rod, a blocking rod and a limiting block, and the blocking rod penetrates through the inclined supporting arm; the safety connection design is arranged on the ladder stand, the limiting arm rod is of an L-shaped structure, the galvanized steel pipe and the limiting arm rod are safely connected on the arc-shaped roof ridge of the steel structure, the fixed rubber wheel is in rolling contact with the arc-shaped roof ridge of the steel structure and can transversely move in the construction process, and the blocking rod blocks constructors. And gravity center unbalance caused by excessive backward leaning of workers on the ladder stand is avoided, so that the workers can safely construct.
