Description

Technical Field

[0001] The utility model relates to the technical field of power maintenance, and particularly relates to a power insulating rod. Background Art

[0002] An insulating rod is a general term for insulating tools dedicated to the power system. It can be used for live working, live maintenance, and live repair. The working tools are mainly insulating tools with end fittings made of insulating tubes or insulating rods.

[0003] Currently, the existing power insulating rod has a relatively simple structure, mostly a single-rod structure assembled by threaded fittings between single rods. However, during high-altitude switch-off operations, due to the influence of gravity and attraction, the joints of the insulating rod are prone to shaking. When the operator holds the bottom tail rod, the situation of instability will occur, resulting in deviation of the operation and easy shaking of the whole insulating rod, making it difficult to perform the switch-off operation. To solve the above problems, a power insulating rod is proposed to solve the above problems. Summary of the Utility Model

[0004] In view of this, the utility model provides a power insulating rod. The utility model can connect and fix the inner threaded joint at the bottom of the top rod with the outer threaded joint at the upper end of the middle rod, and connect and fix the outer threaded joint at the bottom of the middle rod with the inner threaded joint at the upper end of the tail rod. When using the combined power insulating rod with the two side handrails erected, the buffer pad for waist support is used to stabilize the power insulating rod during the switch-off operation, or two people cooperate, one on each side of the handrail to operate the power insulating rod together, which can make the operation more convenient and labor-saving.

[0005] To solve the above technical problems, the utility model provides a power insulating rod, including a top rod, a middle rod, and a tail rod. The bottom surface of the top rod is provided with a sealing component for strengthening and stabilizing the butt joint of the top rod and the middle rod. The bottom surface of the middle rod is provided with a sealing component for strengthening and stabilizing the butt joint of the middle rod and the tail rod. On both sides of the middle part of the tail rod, there are handrails for conveniently holding the tail rod. On both sides of the bottom of the tail rod, there are buffer pads for the abdominal support and stability of personnel. One end of the handrail is provided with a first connecting block for the handrail to be connected to the surface of the tail rod, and the first connecting block is fixed to the surface of the tail rod. The buffer pad is in an arc shape. One end of the buffer pad is provided with a second connecting block for the buffer pad to be connected to the surface of the tail rod, and the second connecting block is fixed to the surface of the tail rod. The handrail and the buffer pad are arranged cross-symmetrically.

[0006] The upper end of the top rod is provided with a switch-off joint for high-altitude power switch-off, and the inner bottom of the top rod is provided with an internal thread for connecting the top rod and the middle rod.

[0007] The inner top of the tail rod is provided with an internal thread for connecting and fixing with an external thread joint, and the bottom of the tail rod is provided with a grip for low-altitude operation, and the grip is in a convex platform shape.

[0008] The upper and lower ends of the middle rod are provided with external thread joints for connecting and fixing with internal threads, and the external thread joints are in threaded fit with the internal threads.

[0009] The sealing assembly includes a first arc-shaped tile and a second arc-shaped tile. The first arc-shaped tile and the second arc-shaped tile are designed with a hollow middle part made of a lightweight insulating material, and the two ends of the first arc-shaped tile and the second arc-shaped tile are fitted together.

[0010] A number of first threaded holes for fixedly placing positioning bolts are provided at both ends of the first arc-shaped tile. The first threaded holes are also used to prevent the positioning bolts from falling off. A number of second threaded holes for connecting the positioning bolts with the second arc-shaped tile are provided at both ends of the second arc-shaped tile, and the first threaded holes correspond to the second threaded holes.
