Thus, labor intensity is reduced, the labor intensity is obviously reduced when personnel work at high altitude, danger of working high above the ground is reduced, and mounting efficiency is improved.

Description

Transmission line overhead ground wire installation riser

technical field

The utility model belongs to the technical field of installation equipment for overhead ground wires of transmission lines, in particular to a lifter for installation of overhead ground wires of transmission lines.

Background technique

When installing the overhead ground wire, it is necessary to advance the ground wire from the pulley, then withdraw the pulley, and fix it on the cross arm with a suspension wire clamp. In the right position, hang the ground wire at the other end, wind it, lift the ground wire, remove the pulley, put the ground wire in the suspension clamp, and install the accessories. This method is very inconvenient to apply. After the ground wire is installed, it is very difficult to remove the iron wire tightly wound on the ground wire. At the same time, there are unsafe factors in the operation process. Due to the limited load-bearing capacity of commonly used iron wires, it is very easy for the wires to break during the ground wire lifting process, causing work interruption and delaying the construction progress. In the previous construction method, due to the heavy weight of the ground wire, the labor intensity was high, resulting in frequent interruptions in work, and when reinstalling, additional man-hours and labor were required to complete. Due to the existence of this problem, the personal safety of high-altitude operations and the economic benefits of enterprises have been seriously affected. Since the ground wire is hung at the highest point of the tower, if a lever block is used, it should be hung on the cross-arm head. When the chain is the shortest, the hook of the lever block is lower than the ground wire. The application of the ground wire accessories process, the tool cannot be used to lift the ground wire for accessory installation.

Utility model content

The technical problem solved by the utility model is to provide a lifter for installation of overhead ground wires of power transmission lines, which is safe in use, low in labor intensity, high in installation efficiency and easy to operate.

In order to solve the above-mentioned technical problems, the technical solution proposed by the utility model is: a rope tightener with a handle, a hook and a housing, a bracket is fixed at the lower end of the housing, and a hook is arranged at one end of the bracket. The other end is provided with a folded edge, and a threaded hole is arranged on the folded edge, and a screw rod is arranged in the threaded hole.

Compared with the prior art, the lifter for installing the overhead ground wire of the transmission line provided by the utility model has the following advantages: because it includes a rope tightener with a handle, a hook and a housing, a bracket is fixed at the lower end of the housing, One end of the bracket is provided with a hook, and the other end is provided with a folded edge, and a threaded hole is arranged on the folded edge, and a screw rod is arranged in the threaded hole. The hook catches the edge of the cross-arm angle iron, then clamps the folded edge on the side of the angle iron, rotates the screw, at this time the bracket is fastened on the cross-arm, hangs the hook on the overhead ground wire, turns the handle, the hook connects the ground wire Elevate, disengage from the pulley, and then install the suspension clamp, which reduces labor intensity. The weight of each overhead ground wire is about 120kg, while using the overhead ground wire of this transmission line to install the lifter, the pulling force is only about 20kg. The labor intensity at high altitude is significantly reduced, reducing the danger of high-altitude operations and improving efficiency.

Description of drawings

Fig. 1 is a schematic structural diagram of a lifter for installing an overhead ground wire of a transmission line.

Detailed ways

The structure of the installation lifter for the transmission line overhead ground wire proposed by the utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, it is a schematic structural diagram of installing a lifter for the overhead ground wire of a transmission line. Its structure includes a rope tightener 4 with a handle 1, a hook 2 and a housing 3. A bracket 5 is fixed at the lower end of the housing 3 of the rope tightener 4. One end of the bracket 5 is provided with a crotch 6, and the other end is provided with a The flange 7 is provided with a threaded hole 8 , and a screw 9 is provided in the threaded hole 8 .

During use, the bracket 5 is placed on the cross arm earlier, the edge of the angle iron of the cross arm is clamped with the crotch 6, then the flanging 7 is stuck on the side of the angle iron, the screw rod 9 is rotated, and the support 5 is fastened on the On the cross arm, hang the hook 2 on the overhead ground wire, turn the handle 1, the hook 2 will raise the ground wire, get off the pulley, and then install the suspension clamp, which reduces labor intensity and the weight of each overhead ground wire It is about 120kg, but using the overhead ground wire of the transmission line to install the lifter, the pulling force is only about 20kg, the labor intensity of personnel at high altitude is significantly reduced, the danger of high-altitude operation is reduced, and the efficiency is improved.

The scope of protection of the utility model is not limited to the above-mentioned embodiments, as long as the structure is the same as that of the lifter for installing the overhead ground wire of the transmission line of the utility model, it falls within the scope of protection of the utility model.
