Description

An insulator universal adapter

technical field

The utility model relates to the field of electric power construction, in particular to a universal conversion joint for insulators.

Background technique

With the vigorous development of my country's electric power industry, electric power technology is also developing all the time, and the technical standards of electric power materials have also changed. For example, for post insulators, under the same voltage level, the diameter of the lower end of the post insulator in the new standard is larger than that specified in the old standard, so when it is necessary to replace the post insulator, we often find the following situations:

The hole diameter of the original cross arm on the column was designed according to the specifications of the old insulators, and the diameter is small, so it cannot be adapted to the new insulators. The reason is that it is difficult for the projects that have been constructed to be updated to the latest models in real time with the development of technology. In the face of maintenance and replacement, especially in emergency repairs, it often takes a lot of time and cost to solve the problem that the connection diameter does not correspond. The most basic thing is to use an electric drill to expand the aperture of the crossarm. However, operating an electric drill under high-altitude operations is technically difficult and there are many potential safety hazards. When the width dimension of the cross-arm itself cannot meet the requirements of the hole diameter, the problem of opening holes will also occur. If the cross arm is replaced, not only will it cause longer power outage time and inconvenience to customers, but the complicated process will also bring greater pressure, cost and risk to the construction.

Embodiment one

As shown in Figures 1-5, the utility model discloses a universal conversion joint for insulators. The structure includes a first support frame 1 above and a bottom plate 2 below. The support frame is a frame formed by welding upper, lower, left and right four square steel plates. An insulator connecting hole is processed in the center of the upper steel plate. The connecting rod of the insulator 5 is inserted into the hole and fixed with a nut or directly screwed to the connecting hole. The bottom plate is a steel plate with the right end bent upwards. The right side of the lower steel plate of the first supporting frame is welded to the bent end of the bottom plate. After welding, a horizontal U-shaped structure with an opening on the left is formed between the lower steel plate and the bottom plate. The U-shaped structure is clamped to the outside of the cross arm. Two threaded holes are processed on the bottom plate.

A long slot hole is processed on each of the left and right steel plates, which can be used to reduce the weight of the device without reducing the overall strength, reduce the burden of the cross arm, and enhance stability.

Embodiment two

An insulator universal conversion joint as shown in Figure 6-8, in this conversion joint, the structure of the upper half of the second support frame 9 is the same as that of the first support frame, the difference is that the upwardly bent bottom plate of the lower half of the first frame is replaced by a corner plate 10 with an opening on the right side, the corner plate is an inverted L-shaped structure formed by welding a horizontal plate and a vertical plate, the right end of the corner plate extends upwards to connect with the right side of the second support frame, the corner plate and the second support frame are welded on the right side, and the upper plate of the corner plate is connected to the second support frame. A gap for accommodating the cross arm is provided between the lower plates, which is also a transverse U-shaped groove with an opening on the left side. The difference is that the lower part of the U-shaped groove extends downward at the left end and is parallel to the vertical plate of the cross arm. The clamping plate and the corner plate, and the clamping plate and the second support frame are connected as a whole through bolts 7, and then the cross arm is firmly clamped.

The use of the universal joint of the insulator avoids the drilling work of the cross arm during the construction process. The new insulator can be installed with the universal joint first, and then the transferred insulator can be installed on the pole, which reduces the time for high-altitude operations, improves work efficiency, and is safer and more convenient.

The use of the universal joint of the insulator also avoids the disassembly of the old insulator during the construction process. The new insulator can be installed with the universal joint first, and then the insulator that has been transferred can be installed on the pole to any position, which reduces the time for high-altitude operations, improves work efficiency, and is safer and more convenient.

The above description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the application.
