Detailed Description
The invention will be further described with reference to the following drawings and specific embodiments:
example (b):
referring to fig. 1, the embodiment provides an adjustable main transformer pile head connecting device, which includes a copper bar 1 and a main transformer pile head 2 with one end fixed; the other end of the main transformer pile head 2 is provided with an external thread section 21; the method is characterized in that: a flitch 5 is arranged on the lower bottom surface of the copper bar 1; a second lug plate 6 is arranged on the other end surface of the flitch plate 5; one end of the connecting plate 7 is hinged on the second lug plate 6, the other end of the connecting plate is hinged on the first lug plate 4, and the first lug plate 4 is fixed on the end face of the outer side of the connecting cylinder 3; an internal thread hole 31 matched with the external thread section 21 on the main transformer pile head 2 is arranged at the middle position of the connecting cylinder 3 along the axial direction, and the main transformer pile head 2 is movably arranged on the connecting cylinder 3 through the matching of the internal thread hole 31 and the external thread section 21.
