The 10kV overhead distribution line network with the largest coverage is responsible for the main connection between the transmission line network and various users. Due to the low insulation level of the voltage level line, it is prone to failure under the action of atmospheric overvoltage, pollution or other external factors, and because the distribution line facilities in some areas are old and aging, there are many hidden dangers in the equipment, coupled with the rapid development of social economy, The ever-increasing number of companies reporting for installation of electricity, and the relocation of 10kV overhead distribution lines caused by infrastructure construction are increasing year by year, which will affect the reliability of the continuous power supply of the distribution network. To reduce power outage lines and outage time, and improve the reliability of distribution network power supply, the main means is to vigorously, comprehensively and safely carry out live distribution work.

At present, when the live work of the distribution network is performed, especially when the straight rod is changed to a tension rod, when the insulating rod operation method and the insulating glove operation method are used to replace the linear rod insulator and the cross arm, most of the lifting devices are used. The traditional lifting device is inconvenient to install, and the height between the wire and the cross-arm cannot be raised twice after being fixed, resulting in a small distance between the wire and the cross-arm, which requires skilled operators to carry out, and the operation is difficult.

In the prior art, lifting mechanisms such as screw rods and ratchet wrenches are often used, and the lifting height is limited. The lifting process is manually operated, which is labor-intensive, and often requires at least two people to take turns to lift the cross arm. Due to the uneven force of manual operation, the lifting mechanism will be twisted, and the lifting mechanism needs to be adjusted, so the operating efficiency is not high. At the same time, during temporary adjustment, it is necessary to climb back to the lifting mechanism at a high altitude, lift the cross arm, and then climb up to the cross arm for operation, which is very time-consuming and laborious.

There are two guide hoops, and a fixed column is connected between the two guide hoops.

It also includes a manual switch, a control box, and a lithium battery, the electric push rod is connected with the control box, and the manual switch, the lithium battery are electrically connected with the control box.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model is suitable for 10kV load-carrying horizontal overhead line straight rods to be changed into tension rods and equipped with on-column switch wires, and can be applied live whether it is an insulated line or a bare wire line, and can effectively control the air between the wires and the cross arm. Clearance and safety distance. The specific advantages are:

1. The labor intensity of on-site personnel has been reduced from 3-5 operators to one person to lift the wire, and the original manual height adjustment has been changed to electric adjustment.

2. Two guiding hoops are used together with the supporting hoops to avoid twisting of the pole during the lifting process. During the whole operation process, there is no need to adjust the device.

3. Due to the use of electric push rods, the working time is shortened, which is half of the original working time.
