Detailed description of the invention
Embodiments of the invention are described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2,
a kind of steel pile pipe internal-expansion type hangs a device, comprise hanger 1, central axis 2, Hollow hydraulic cylinder 3, Connection Block 5, balance arm 6, guide cylinder cylinder 7, move radially voussoir 8, move axially cone voussoir 9, load-bearing baffle ring 10, tough stake plate 11, expanding friction plate 12 and expanding bolt 13, hanger 1, central axis 2, Hollow hydraulic cylinder 3, Connection Block 5, guide cylinder cylinder 7, move axially cone voussoir 9, load-bearing baffle ring 10 is installed on same axis successively, form one and drive cone; Hanger 1, Hollow hydraulic cylinder 3 are positioned at the top of central axis 2, move axially cone voussoir 9, bottom that load-bearing baffle ring 10 is positioned at central axis 2; Hollow hydraulic cylinder 3 is connected with Connection Block 5 top by connecting bolt 4, and guide cylinder cylinder 7 is connected with Connection Block 5 bottom by connecting bolt 4, welding balance arm 6 on Connection Block 5, and central axis 2 is through Connection Block 5; Move axially uniform processing T type groove on cone voussoir 9, taper seat, coordinate with the T-shaped beam moved radially on voussoir 8; The circumferential uniform rectangular window of guide cylinder cylinder 7, and moves radially voussoir 8 and coordinates.
described hanger 1, central axis 2, Hollow hydraulic cylinder 3 and move axially centrum voussoir 9, load-bearing baffle ring 10 is independently parts, forms driving cone through cold installations.
