Abstract
A full floating connecting support is welded on an auxiliary frame. Guiding anti-shear sleeves I are arranged in connecting holes of an upper connecting plate, and flanges of the guiding anti-shear sleeves I are lapped on the upper connecting plate. High strength bolts are disposed in holes of the guiding anti-shear sleeves I, and guiding anti-shear sleeves II are sleeved on outsides of the guiding anti-shear sleeves I. The guiding anti-shear sleeves II are disposed in connecting holes of a lower connecting plate, and flanges of the guiding anti-shear sleeves II are lapped on the lower connecting plate. Lower portions of the guiding anti-shear sleeves II are in sleeve joint with springs with rectangular sections, and the springs with the rectangular sections are connected to lower ends of the high strength bolts by load-bearing gaskets and nuts. A composite elastic element is disposed between the upper connecting plate and the lower connecting plate. The high strength bolts, the guiding anti-shear sleeves I and the guiding anti-shear sleeves II jointly penetrate through connecting holes of the composite elastic element.
