Special transport ladder for mutual inductor expander

Abstract

The invention relates to a special transport ladder for a mutual inductor expander, and belongs to the technical field of electric power maintenance equipment. The transport ladder comprises a ladderbody, a frame body, a rotating shaft, rotating rings and two containing cabinets, wherein the rotating rings are positioned at the two ends of the rotating shaft correspondingly and are fixedly connected with the rotating shaft by virtue of supporting rods, the two containing cabinets are symmetrically arranged along the axes of the rotating rings, the rotating rings are hinged to the two sides ofthe frame body by virtue of the rotating shaft, the containing cabinets each have a lifting degree of freedom by means of the rotating rings, and the frame body is fixedly connected with a mounting rod through a connecting piece; and taking and placing openings with cabinet doors are formed in the side walls of the containing cabinets, the taking and placing opening of the containing cabinet located at the highest position is higher than the top end of the frame body, and an avoiding hole for the taking and placing openings is formed in the lower end of the frame body. According to the special transport ladder, the rotating rings is controlled to rotate by a worker so that lifting of the mutual inductor expander can be achieved, then time and labor are saved, falling accidents are effectively avoided, and safety and reliability are high.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance equipment, and relates to a transport ladder, in particular to a special transport ladder for a transformer expander. Background technique [0002] When changing the current transformer expander from a box-type expander to a corrugated expander according to production needs, the original box-type expander on the installation rod needs to be removed during the replacement process, and the original box-type expander on the installation rod should be removed by the personnel above the operation The box expander is lowered to the ground, and the new corrugated expander is pulled over and installed. Due to the large size and medium weight of the box-type expander, once it is placed on the ground, improper transmission will cause damage to the porcelain sleeve of the current transformer, and the weight of the expander will easily cause joint injuries to the workers. Falling from a hi...

Problems solved by technology

Due to the large volume and medium weight of the box-type expander, once it is placed on the ground, improper transmission will cause damage to the porcelain sleeve of the current transformer, and the weight of the expander will easily cause joint injuries to the workers. Falling from a high altitude, the operation is difficult and the risk factor is high
