Problems solved by technology

During the construction of voltage transformers and current transformers, due to the influence of the secondary cable through the pipe, the ladder cannot directly lean on the equipment pole but only on the cable pipe, and often directly leans on the cable through the pipe for binding. , the ladder is only under a little force, which cannot meet the requirements for safe use

Abstract

The invention discloses an adjustable ladder supporting frame, and relates to the field of power construction. During voltage transformer\current transformer construction, due to the secondary cable pipe penetrating influence, a ladder cannot directly lean on an equipment rod while can only lean on a cable pipe, and the safety using requirement cannot be met. The adjustable ladder supporting framecomprises a supporting frame body, embracing claws and a connecting fixing device. The supporting frame body comprises a left supporting rod and a right supporting rod which are symmetric left and right. The embracing claws include the arc left embracing claw and the arc right embracing claw which are arranged at the front end of the left supporting rod and the front end of the right supporting rod correspondingly and can forwards and backwards contract and stretch and be fixed. An adjustable cross rod is arranged between the rear portions of the left supporting rod and the right supporting rod so that the distance between the rear portions of the left supporting rod and the right supporting rod can be adjusted. An adjustable connecting locking device is arranged between the front portions of the left supporting rod and the right supporting rod so as to lock the equipment rod through the embracing claws. The technical scheme can conveniently adapt to single ladders different in size,the single ladder construction safety is improved, safety accidents are reduced, and life guarantee and operation efficiency are improved.

Description

Technical field [0001] The invention relates to the field of electric power construction, in particular to an adjustable ladder support frame. Background technique [0002] At present, in the process of engineering construction, a large number of single-ladder operations are required for equipment installation. In order to meet the safety of construction, the ladder is leaned on the equipment pole at a 60-degree angle and then tied and fixed with hemp rope to prevent the side slip and fall and improve the safety of the single ladder. During the construction of voltage transformer / current transformer, due to the influence of secondary cable penetration, the ladder cannot lean directly on the equipment pole but can only lean on the cable pipe, often directly leaning on the cable pipe for binding use , The ladder has only a little force and cannot meet the requirements for safe use. Summary of the invention [0003] The technical problem to be solved and the technical task proposed...
