Description

A spanning device for erecting transmission lines

technical field

The utility model relates to a spanning device for erecting transmission lines.

Background technique

At present, when renovating and erecting new overhead line conductors, because there are many horizontal communication lines, steel strands, cable television cables, etc. along the street, the conductors cannot be smoothly crossed when the wires are released, and it is necessary to hold the wires and throw them over obstacles, which is inconvenient and time-consuming. strenuous.

Contents of the invention

In order to solve the above technical deficiencies, the utility model provides a spanning device for erecting transmission lines which is convenient to operate and saves time and effort.

The utility model is achieved through the following measures:

A spanning device for erecting transmission lines according to the utility model includes a base and a counterweight. Universal wheels are arranged at the bottom of the base, and a turntable is rotatably connected to the top of the base. An electric lifting rod is vertically arranged on the turntable. An electric telescopic rod is arranged horizontally on the top of the electric lifting rod. The electric telescopic rod includes a base and a telescopic rod body. The front bottom of the base is fixedly connected with the top of the electric lifting rod. The end of the telescopic rod body is provided with a small pulley, and the end of the telescopic rod body is connected with a limit frame located outside the small pulley, and the turntable is provided with a battery electrically connected to the electric lifting rod and the electric telescopic rod.

The above-mentioned limiting frame is C-shaped, and the two ends of the limiting frame are respectively connected to both sides of the end of the telescopic rod body. A threading channel is formed between the limiting frame and the small pulley, and the area of the threading channel is smaller than the cross-section of the counterweight.

The beneficial effect of the utility model is that the wire can be conveniently passed over the obstacle cables along the street horizontally during unwinding, and it is not necessary to hold the wire to throw over the obstacle cables, and the operation is convenient, time-saving and labor-saving.

Description of drawings

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

Among them: 1 base, 2 universal wheels, 3 turntables, 4 electric lifting rods, 5 telescopic rods, 6 counterweights, 7 limit frames, 8 small pulleys, 9 large pulleys, 10 bases, 11 batteries.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figure 1, a spanning device for erecting power transmission lines of the present utility model includes a base 1 and a counterweight 6, the bottom of the base 1 is provided with a universal wheel 2, and a turntable 3 is connected to the top of the base 1 for rotation, and on the turntable 3 An electric lifting rod 4 is vertically arranged, and an electric telescopic rod is arranged horizontally on the top of the electric lifting rod 4. The electric telescopic rod includes a base 10 and a telescopic rod body 5. The rear top of 10 is provided with a large pulley 9, and the end of the telescopic rod body 5 is provided with a small pulley 8, and the end of the telescopic rod body 5 is connected with a limit frame 7 positioned at the outside of the small pulley 8. The storage battery 11 that is electrically connected with the electric telescopic rod. The limiting frame 7 is C-shaped, and the two ends of the limiting frame 7 are respectively connected to both sides of the end of the telescopic rod body 5, and a threading channel is formed between the limiting frame 7 and the small pulley 8, and the area of the threading channel is smaller than the transverse weight of the counterweight 6. section.

During use, wire is wound on the big pulley 9 and the small pulley 8 successively, and the end of the wire is connected to the counterweight 6 after going around the small pulley 8, and the counterweight 6 is suspended outside the cantilever. Raise the electric lifting rod 4 to an appropriate height, so that the height of the cantilever exceeds the height of the cable that needs to be crossed, then move the base 1 to the vicinity of the cable that needs to be crossed, turn the turntable 3, start the electric telescopic rod, and move the end of the telescopic rod body 5 The counterweight 6 straddles other cables, and under the action of gravity of the counterweight 6, the wires are gradually lowered, thereby realizing the wire crossing operation. During the action of the electric lifting rod 4 and the electric telescopic rod, the operator pulls the wire and slowly relaxes it at the same time, so that the wire gradually rises and stretches forward, because the counterweight 6 cannot pass through the limit frame 7, so it can prevent the distribution Weight 6 and lead are pulled down.

The above description is only the preferred implementation mode of this patent. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of this patent, some improvements and replacements can also be made. These improvements and replacements It should also be regarded as the scope of protection of this patent.
