Description

Retractable Linear Insulator Ladder

technical field

The utility model relates to electric tools, in particular to an insulator ladder.

Background technique

At present, when the line is powered off for maintenance, it is either climbing up with the help of professional tools, or directly going up and down along the insulator string. Professional tools are bulky and inconvenient to carry. The insulator strings may be damaged along the insulator strings, or slipping and jamming will occur, which will affect the safety of work.

Utility model content

The technical problem to be solved by the utility model is to provide a retractable linear insulator ladder, which can avoid damage to the insulator string, or slipping and jamming when directly going up and down along the insulator string, so as to ensure the safety of operators.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: the scalable linear insulator ladder is used to connect the cross arm and the wire, including a cylindrical ladder main body and a telescopic rod passing through the ladder main body. The top is provided with a cross-arm clamp, the cross-arm clamp is provided with an internal thread, the telescopic rod is provided with a threaded section connected with the internal thread, and the cross-arm clamp is provided with a connection for connecting the ladder to the cross-arm Groove, the bottom of the telescopic rod passes through the bottom of the main body of the ladder and is provided with a wire hook connected to the wire. When the telescopic rod shrinks upward, the wire hook tightens the wire. Stairs to step on.

Preferably, the ladder is tightly fixed to the main body of the ladder through a hoop.

Preferably, the clamping head of the cross arm is connected with a locking screw for locking the cross arm in the connecting groove.

Preferably, an adjustment rod perpendicular to the telescopic rod is connected to the top of the telescopic rod.

The technical scheme adopted by the utility model, when the power is cut off for maintenance, the stretchable linear insulator ladder is used to connect the cross arm and the wire, and the operator can directly go up and down along it, avoiding damage to the insulator string when going up and down directly along the insulator string, or Slipping and jamming occur, saving time and effort, ensuring the safety of operators, and improving work efficiency.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

Fig. 1 is the structural representation of the utility model.

detailed description

As shown in Figure 1, the ladder with retractable linear insulators is used to connect the cross arm and the wire, including a cylindrical ladder body 10 and a telescopic rod 12 passing through the ladder body, the top of the ladder body is provided with a cross arm Chuck 13, described cross-arm chuck is provided with internal thread, and described telescoping rod is provided with the thread section that is threadedly connected with internal thread, and described cross-arm chuck is provided with the connection groove 131 that makes climbing ladder and cross-arm connected, so The bottom of the telescopic rod passes through the bottom of the ladder main body and is provided with a wire hook 121 connected with the wire. The top of the telescoping rod is connected with an adjusting rod 122 perpendicular to the telescopic rod, and the length of the telescopic rod 12 is adjusted by adjusting the rod 122, so that the climbing ladder is tightened, and is firmly connected with the cross arm and the wire. When the telescopic rod is upwardly contracted, the wire hook tightens the wire.

Among them, the design length of the main body of the ladder is 1002mm, which meets the requirements of the shortest insulator string for 110kV lines, and is used to fix the steps, cross-arm clamps, and telescopic rods. The main body of the ladder is provided with steps 11 along the axial direction for operators to step on. The design spacing of the steps is 180mm, which is convenient for workers to step on. The steps 11 are tightly fixed to the main body 10 of the ladder through the hoop 111 , and at the same time, the hoop 111 is provided with screws 112 to lock the main body 10 of the ladder to prevent the steps 11 from slipping.

The clamping head 13 of the cross arm is connected with a locking screw 132 that locks the cross arm in the connection groove, so that the ladder and the cross arm are firmly in contact, and there is no slipping or loosening when climbing.
