Description

Technical Field

[0001] The invention relates to the field of electric power equipment, and in particular to a high-strength electric pole heightening section. Background Art

[0002] The utility pole heightening section is a device that can conveniently increase the capacity of utility pole installation, which effectively avoids the cost issues such as land acquisition and construction caused by the new buried utility pole. However, the existing utility pole heightening section is only a simple metal tubular body, which is fixed by a clamp after being put on the upper end of the utility pole. The problem caused by this is that the strength of the utility pole heightening section is limited. Under the pulling of the cable and the blowing of wind, the utility pole heightening section is prone to bending and damage. In addition, since the utility pole is not a regular cylinder, but a thin top and a thick bottom shape, after the existing utility pole heightening section is put on the upper end of the utility pole, there will be a large gap between the upper end of the utility pole and the inner wall of the utility pole heightening section. Due to the gap, under the pulling of the cable, the utility pole heightening section tends to shake, and it is almost entirely dependent on the contact part between the lower part of the utility pole heightening section and the utility pole and the strength of the clamp, which makes the utility pole heightening section damage faster, which is more unfavorable for the long-term and stable operation of the utility pole heightening section. Summary of the invention

[0003] In view of the problems existing in the background technology, the purpose of the present invention is to provide a high-strength utility pole heightening section, which effectively solves the problems existing in the background technology.

A threaded rod 11 is screwed to the lower part of the internal threaded sleeve 9, and a mounting plate 12 is welded to the lower end of the threaded rod 11. Four wedge blocks 13 are evenly distributed on the outer circumference of the mounting plate 12. The wedge blocks 13 are metal blocks or hard wood blocks. When the wedge blocks 13 are metal blocks, they can be welded to the mounting plate 12. When the wedge blocks 13 are hard wood blocks, they can be fixed to the mounting plate 12 by horizontal screws. A clearance hole 14 corresponding to the wedge blocks 13 is opened on the top surface of the inner tube 1.

[0022] Two heightening blocks 15 are welded on the top surface of the outer cylinder 2, and the cross arm 3 is welded on the heightening blocks 15 to leave space for the screwing of the screwing part 10. The top surface and the bottom surface of the outer cylinder 2 are respectively provided with an upper cover 16 and a lower cover 17 to facilitate the assembly of the heightening section of the electric pole. Specifically, when assembling the heightening section of the electric pole, the annular ribs 7 on the inner wall of the outer cylinder 2 are first welded in sequence. When welding the lower annular rib 7, in addition to spot welding the outer periphery of the annular rib 7 to the inner wall of the outer cylinder 2, the inner periphery of the annular rib 7 is also spot welded to the outer wall of the inner cylinder 1 to complete the fixation of the inner cylinder 1 and the outer cylinder 2.

When the screwing part 10 is difficult to screw, it means that the wedge block 13 is tightly wedged in the gap between the upper end of the pole 4 and the inner upper part of the inner tube 1. At this time, the pole heightening section is in good contact and tight fit with the pole 4. The pole heightening section no longer has a tendency to shake, which reduces the stress on the lower part of the inner tube 1 and the clamp 5, and effectively ensures the long-term stable operation of the pole heightening section. In addition, the application of the annular ribs 7 and the vertical reinforcing rods 8 makes the pole heightening section stronger and less prone to bending.
