Problems solved by technology

[0004] This case shows that although it is possible to increase the support area and frictional force by installing rubber sheaths at the bottom support points to achieve the effect of preventing the ladder from tipping over, the stability of the contact between the left and right sides of the ladder and the ground It is poor, and it is difficult to improve the anti-dumping effect of the ladder only by increasing the friction between the inclined rod and the ground. Therefore, an anti-dumping ladder for power grid infrastructure is needed

Abstract

The invention discloses an anti-toppling combined ladder for power grid capital construction. The anti-toppling combined ladder comprises a connecting plate. Hinging blocks are fixedly connected to the left side wall and right side wall of a connecting plate. Side ladder frames are rotationally connected to the hinging blocks on the two sides. A balance bottom plate is arranged between adjacent inner walls of the side ladder frames. Two shaft pins are symmetrically and fixedly connected to the outer side wall of the balance bottom plate. The end portions of the two shaft pins penetrate throughthe surfaces of the side ladder frames. A positioning hole is formed in the surface of the balance bottom plate. According to the anti-toppling combined ladder for power grid construction, a positioning pin is connected in the positioning hole through the matching connection between a u-shaped clamping plate and the balance bottom plate, so that the clamping effect of the balance bottom plate andthe u-shaped clamping plate is realized, the structure of the bottom end of the combined ladder is integrated, and the anti-toppling effect of the combined ladder is improved; and a base shell is additionally arranged, so that the bearing capacity of the bottom end of a longitudinal guide rod and the bearing capacities of the bottom ends of the side ladder frames are distributed in a damping convex block in the base shell, the stability of the bottom end of the combined ladder is improved, and the anti-toppling effect of the combined ladder is achieved.

Description

technical field [0001] The invention belongs to the technical field of combined ladders, and in particular relates to an anti-dumping combined ladder for grid infrastructure. Background technique [0002] In the process of substation infrastructure construction, the phenomenon of toppling of ladders often occurs, and ladders are unsafe in work. Most construction sites adopt the method of one person working on escalators and one person working to prevent this phenomenon, but this increases In addition to uncertain factors, there have been accidents where tools fell and injured escalator personnel. Through on-the-spot inspection, investigation and analysis, the inventor found that the two main causes of the toppling of the combined ladder are the insufficient side support moment of the combined ladder and the pressure of the combined ladder on the ground. [0003] According to the patent CN201120512537.8, a substation infrastructure construction ladder anti-dumping device, th...
