The utility model has the following advantages: when using the combined ground wire lifter to install the overhead ground wire, the staff first firmly fix the combined ground wire lifter on the ground wire cross arm First, adjust the angle and height through the adjustment device according to the work needs, put the traction rope into the pulley to lift the ground wire until it reaches the installation position, put the overhead ground wire into the ground wire clamp and then release the traction, remove the traction rope and combined type The ground wire lifter shall be installed as an accessory according to the construction process. By using the combined ground wire lifter to lift and install the ground wire, the working time can be shortened, the work efficiency can be improved, the labor intensity can be reduced, and the construction safety on site can be ensured. It is safe, convenient and fast to install overhead ground wires on 35KV-500KV lines, improve work efficiency, reduce power outage time, and enhance safety and reliability.

Description

Combined Ground Lifter

technical field

The utility model relates to a lifting installation tool for overhead ground wires of 35KV-500KV power transmission lines.

Background technique

Over the years, the lifting of the overhead ground wire is not in place, and the installation is completed by lifting the shoulders, which is time-consuming and labor-intensive and fails to meet the safety requirements. Sometimes the installation height cannot be reached when lifting the ground wire with the wire lifter, and the wire lifter does not have a firm fixed position, which often causes deformation of the tower material. The installation of the ground wire has caused certain difficulties.

Contents of the invention

The purpose of this utility model is to provide a combined ground wire lifter to overcome the above disadvantages.

The purpose of this utility model is achieved through the following technical solutions:

A combined ground wire lifter, comprising a main body of the ground wire lifter, the main body is fixed on the cross arm, the trolley boom is arranged on the upper end of the ground wire lifter main body through a universal joint, and one end of the trolley boom is provided with a lifting block, The other end of the tackle boom is hinged with the tackle boom adjustment device.

In the aforementioned combined ground wire lifter, the trolley arm adjustment device includes a screw rod and a screw base matched with the screw rod, and the screw base is fixed on the cross arm by bolts.

Adopting the above-mentioned technical scheme, the utility model has the following advantages: when using the combined ground wire lifter to install the overhead ground wire, the staff first firmly fix the combined ground wire lifter on the ground wire cross arm, and adjust the Adjust the angle and height of the device, put the traction rope into the pulley to lift the ground wire until it reaches the installation position, put the overhead ground wire into the ground wire clamp and then release the traction, remove the traction rope and the combined ground wire lifter, and press the construction Process for accessory installation. By using the combined ground wire lifter to lift and install the ground wire, the working time can be shortened, the work efficiency can be improved, the labor intensity can be reduced, and the construction safety on site can be ensured. It is safe, convenient and fast to install overhead ground wires on 35KV-500KV lines, improve work efficiency, reduce power outage time, and enhance safety and reliability.

Description of drawings

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

Detailed ways

A combined ground wire lifter as shown in Figure 1 includes a ground wire lifter main body 1, the main body 1 is fixed on the cross arm, the trolley boom 2 is arranged on the upper end of the ground wire lifter main body 1 through a universal joint, and the trolley One end of the boom 2 is provided with a lifting tackle 3, and the other end of the tackle boom 2 is hinged with the tackle boom adjustment device 4, and the tackle boom adjustment device 4 includes a screw rod and a screw base matched with the screw rod, and the screw rod The base is fixed on the cross arm by bolts.

The height adjustment is realized by turning the screw rod, and the angle adjustment is realized by installing the screw rod of the adjustment device on different positions of the cross arm.

The device of the utility model can be firmly fixed on the cross arm of the ground wire, which is smart and convenient, and cooperates with the pulley at the front end to lift the ground wire to save time and effort. Solve the problem that the ground wire cannot be lifted in place and the wire lifter cannot be fixed in the existing maintenance work.

The combined ground wire lifter is made of solid materials as the main body, so that it can be firmly fixed on the ground wire cross arm. After the staff installs the combined ground wire lifter, they can use the lever principle to adjust the height and angle of the lifter to make the ground wire reach the installation position. Improve work efficiency and enhance safety and reliability. It is safe, convenient and fast to install overhead ground wires on 35KV-500KV lines, improve work efficiency, reduce power outage time, and enhance safety and reliability.
