Description

Ground Lifting Device

technical field

The utility model relates to a ground wire lifting tool for transmission and distribution lines in an electric power system.

Background technique

Power transmission and distribution lines are affected by external forces such as wind force and mechanical vibration for a long time. The metal fittings connecting the tower and the ground wire will be rusted and worn. Now the hand hoist method is often used, but the hand hoist is not tightly connected to the ground wire, it is easy to slip, the safety of the operators cannot be guaranteed, and it is time-consuming, laborious, inefficient, and the tools are heavy.

Contents of the invention

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

Realize the purpose technical scheme of the present utility model as follows:

A ground wire lifting device, including a fixed frame, a set of telescopic hook devices are respectively arranged at both ends of the fixed frame, a groove with an opening downward is arranged in the middle of the fixed frame, a left bracket and a right bracket are symmetrically arranged on the fixed frame, and the left and right brackets are arranged symmetrically. The bracket is hinged to the left gear lever, and the right bracket is hinged to the right gear lever. When both the left gear lever and the right gear lever are turned inward to a horizontal position, the adjacent ends are detachably connected by bolts.

The above-mentioned ground wire lifting device, the telescopic hook device is connected to the left sleeve and the right sleeve at both ends of the fixed frame, a screw rod is provided in the sleeve, and a hook is provided at the lower end of the screw rod, and a gear with a gear is also provided in the sleeve. The rotating shaft, the gear on the rotating shaft meshes with the screw thread on the screw rod, and the crank handle is installed on the rotating shaft extending out of the sleeve, and there is a through hole for inserting the anti-reverse column on the sleeve corresponding to the crank handle, and the anti-reverse post passes through the rope. fixed on the sleeve.

Adopting the above technical scheme, the utility model has the following advantages: the fixed frame is connected to the ground wire on the transmission and distribution line at one end, and the two sets of telescopic hook devices are respectively connected to the two ground wires, and the connection of the ground wire can be adjusted by shaking the handle The degree of tightness, after adjusting to the required tightness, insert the anti-reverse column into the through hole, the anti-reverse column will block the crank so that the crank cannot be rotated, which can effectively prevent the crank from turning upside down. The angle iron is set in the groove of the fixed frame, and the left and right gear levers play the role of limiting and facilitating disassembly and assembly. It is easy to operate and high in safety when working at high altitudes. The utility model has the advantages of simple structure, low cost, convenient maintenance, strong field applicability, and convenient installation and disassembly.
