Description

Foundation adjustment device for power transmission poles and towers in goaf

technical field

The utility model relates to a foundation adjustment device for power transmission poles and towers in goafs, belonging to the technical field of power transmission poles and towers.

Background technique

The goaf is a "hole" created by human excavation or natural geological movement below the surface. The existence of the goaf makes the production and life on the ground face great safety problems. These problems also profoundly affect the safety of transmission lines and towers. Especially in recent years, my country's site disasters have occurred frequently, which has put forward a severe test for transmission towers. It is unrealistic to completely modify the line to bypass the goaf, and the cost of frequent maintenance and repairs is too high and the prerequisites such as power outages are not practical. Not economical either.

Utility model content

The utility model overcomes the deficiencies of the prior art, and the technical problem to be solved is: to provide a foundation adjusting device capable of realizing safe installation of power transmission towers in goaf areas and convenient maintenance.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: the goaf power transmission tower foundation adjustment device, including three layers of steel plates, the fixed plate, the connecting plate and the adjusting plate, and the lower part of the connecting plate is welded to the fixed plate through the steel plate Together, the upper part of the connecting plate is vertically provided with a plurality of screw rods, the upper end of the screw rod passes through the adjusting plate, and the adjusting plate is fixed on the screw rod through the adjusting nuts on both sides, and the upper part of the adjusting plate is fixedly equipped with transmission tower angle steel stand base.

The fixing plate is provided with holes for connecting and fixing with the concrete base.

The screw rod adopts a screw rod of Φ36.

There are 8 screws.

Compared with the prior art, the utility model has the beneficial effects that: the utility model can keep the tower always vertical by adjusting the bolt, the tower body is stable, safe and reliable, and can well adapt to the geological conditions of the goaf, and the whole device Simple structure, convenient installation, use and maintenance, and strong practicability.

Description of drawings

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

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

In the figure: 1 is a fixing plate, 2 is a connecting plate, 3 is an adjusting plate, 4 is a screw rod, 5 is an adjusting nut, 6 is a base of a power transmission tower angle steel frame, and 7 is a concrete base.

Detailed ways

As shown in Figure 1, the utility model goaf power transmission pole tower foundation adjustment device comprises three layers of steel plates of a fixed plate 1, a connecting plate 2 and an adjusting plate 3, and the lower part of the connecting plate 2 is welded together with the fixed plate 1 through a steel plate, The upper part of the connecting plate 2 is vertically provided with a plurality of screw rods 4, the upper end of the screw rod 4 passes through the adjusting plate 3, the adjusting plate 3 is fixed on the screw rod 4 by the adjusting nuts 5 on both sides, and the upper part of the adjusting plate 3 is fixed The transmission pole tower angle steel frame base 6 is installed.

The fixing plate 1 is provided with a hole convenient to be connected and fixed with the concrete base 7. In this specific embodiment, the fixing plate 1 is fixed on the concrete base 7 by bolts, and the fixing plate 1 can also be fixed on the concrete base 7 by other means. , such as directly encapsulating the fixing plate 1 in the concrete structure of the concrete base 7 .

The screw 4 adopts a screw of Φ36, and there are 8 screws 4. The screw 4 can offset the uplifting force transmitted by the tower. At the same time, by adjusting the height of the adjustment plate 3 on the screw 4, the tower can also be balanced so that it always maintains Vertical; in the process of using the utility model, the number is determined according to the number of brackets of the angle steel frame of the pole tower, for example, a pole tower with four brackets, a set of the device described in the utility model is installed at the bottom of each bracket, by adjusting The four brackets have different adjustment devices to keep the tower always vertical and the tower body is stable, which can well adapt to the geological conditions of the goaf.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made, these improvements and modifications It should also be regarded as the protection scope of the present utility model.
