Insulated hanging ladder for equipotential work

Abstract

The invention discloses an insulated hanging ladder specially used for equipotential operation and belongs to the technical field of electric operation devices. The insulated hanging ladder comprises a base frame, a stool plate for sitting and a supporting rod for supporting the stool plate. One side of the stool plate is rotatably connected to the base frame. One end of the supporting rod is rotatably connected to the base frame and below the connecting part of the stool plate and the base frame, and the other end of the supporting rod when in use is matched with the stool plate to fix and support the stool plate. According to the insulated hanging ladder, the stool plate and the supporting rod used for supporting the stool plate are rotatably connected to the base frame, and therefore the structure of the hanging ladder is more humanized, a worker can sit on the stool plate when entering or leaving equipotential electrified cables and using comfortableness is obviously improved. In addition, consumption of a lot of energy of a worker to make the hanging ladder balanced when the worker enters or leaves is not needed, requirements on worker control skills are greatly reduced, and muscle power consumed when the worker enters or leaves is small, thus ensuring work security.

Description

technical field [0001] The invention relates to the technical field of electric power operation equipment, in particular to an insulating hanging ladder specially used for equipotential work. Background technique [0002] According to the principle of electrical engineering, equipotential is equal potential. If there is no potential difference between two points in the same live line, there will be no current between these two points, and the potentials of these two points will be equal. The equipotential operation in electric operation is to use this principle to make the potential of each part of the operator and the potential of the point wire always equal, there is no potential difference between the two, and no current flows through the operator during the operation, so as to ensure the safety of the operator. personal safety of personnel. [0003] At present, when operators use the swing-in method to enter the live wires for equipotential work, they generally take an ...

Problems solved by technology

[0004] 1. Restricted by the "shi"-shaped structure of the hanging ladder, the operator needs higher control skills when entering and exiting the hanging ladder, otherwise it is not easy for the operator to keep himself in a balanced state during the operation, which will affect the normal operation, and the structure of this structure Hanging ladders are only suitable for thinner workers;

[0005] 2. When this kind of hanging ladder is used for UHV line operation, due to the large size of the tower head of the UHV line, the potential transfer process takes a long time, and the operator takes a long time to ride the hanging ladder. Therefore, the operator needs to control the time for body balance Long, consumes a lot of energy, and relatively low safety;

[0006] 3. When carrying out equipotential work on UHV lines, the operator needs to carry the potential transfer rod with him. Since there is no auxiliary hanging point on the "shi"-shaped ladder, the potential transfer rod cannot be hung on the ladder, and the operator must always hold it Potential transfer rod, which increases the difficulty of operation;

[0007] 4. The "shi"-shaped ladder adopts a single lifting point structure, and the operator will spin when riding the ladder, and the operator cannot control the direction of rotation, which is not conducive to operation
