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 ...

Examples

Embodiment 1

[0037] like figure 1 , 2 As shown, the special insulation hanging ladder for equipotential work provided by the embodiment of the present invention includes a base frame 1, a stool 2 for riding and a support rod 3 for supporting the stool 2, and one side of the stool 2 is rotatably connected to the The base frame 1, one end of the support rod 3 is rotatably connected to the base frame 1 and is located below the connection between the stool and the base frame, and the other end of the support rod 3 cooperates with the stool board 2 to fix and support the stool board during use.

[0038] The base frame 1 is in the shape of a "king" or a "non" and includes a vertical rod 11, a top rod 12 arranged at the top of the vertical rod, a bottom rod 13 arranged at the bottom of the vertical rod, and a bottom rod between the top and the bottom of the vertical rod. The cross bar 14 , in this embodiment, the cross bar 14 is arranged at the middle part of the vertical bar 11 or at a position...

Embodiment 2

[0053] The difference between this embodiment and the above-mentioned embodiment 1 is that the thickness of the stool board 2 is relatively large, and the bottom surface of the stool board is provided with a draw-in groove on the side away from the base frame 1 to cooperate with the top of the support rod 3. When the support rod 3 is in use The supporting stool 2 is fixed through the cooperation of the top end and the draw-in groove.
