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 pile hanging device, including hanger 1, central shaft 2, Hollow hydraulic cylinder 3, connect seat 5, balance arm 6, guide cylinder cylinder 7, move radially voussoir 8, move axially cone voussoir 9, load-bearing baffle ring 10, tough peg board 11, expanding friction plate 12 and expanding bolt 13, hanger 1, central shaft 2, Hollow hydraulic cylinder 3, connect seat 5, guide cylinder cylinder 7, move axially cone voussoir 9, load-bearing baffle ring 10 is installed on same axis successively, form one driving cone；Hanger 1, Hollow hydraulic cylinder 3 are centrally located the top of axle 2, move axially cone voussoir 9, load-bearing baffle ring 10 is centrally located the bottom of axle 2；Hollow hydraulic cylinder 3 is connected with being connected seat 5 top by connecting bolt 4, and guide cylinder cylinder 7 is connected with being connected seat 5 bottom by connecting bolt 4, connects welding balance arm 6 on seat 5, and central shaft 2 is through connecting seat 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, coordinates with moving radially voussoir 8。
Described hanger 1, central shaft 2, Hollow hydraulic cylinder 3 and move axially vertebral body voussoir 9, load-bearing baffle ring 10 is independent parts, through supercool install to be formed drive cone。
As shown in Figure 3: coordinate with load-bearing baffle ring 10 bottom described guide cylinder cylinder 7, the guide effect moved radially is acted；Load-bearing baffle ring 10 is threadeded with central shaft 2 lower end, overcomes the thrust that oil cylinder produces；Tough peg board 11 is connected with load-bearing baffle ring 10 bolt。
As shown in Figure 4,5: described moves axially the N number of T-slot of uniform processing on cone voussoir taper seat, and this groove coordinates with N number of T-shaped beam moved radially on voussoir 8, move axially cone voussoir 9 with the wedge angle moving radially voussoir 8 less than 8 degree, there is self-lock ability。
The described guide cylinder cylinder 7 uniform N number of rectangular window of circumference, rectangular window is identical with moving radially voussoir 8 quantity, and coordinates with moving radially voussoir 8。
Described expanding friction plate 12 is connected with moving radially voussoir 8 by expanding bolt 13, and expanding friction plate 12 is textured with the processing of pile pipe contact surface, and the expanding friction plate 12 of the pile pipe replacing different-thickness according to different inner diameters。
When described hydraulic lock 14 lost efficacy for oil circuit, it is ensured that hydraulic cylinder keeps duty constant。
Described hanger 1, central shaft 2, move axially cone voussoir 9, load-bearing baffle ring 10 is forge piece respectively。
Operation principle is:
The driver part that the present invention adopts is independently of the Hollow hydraulic cylinder 3 outside cone。
When Hollow hydraulic cylinder 3 cavity of resorption enters hydraulic jack, under the effect of hydraulic oil, oil cylinder piston promotes cylinder piston rod, promotes hanger 1 to move to the left。Hanger 1 drives central shaft 2 to be moved to the left。Central shaft 2 moves axially cone voussoir 9 by load-bearing baffle plate 10 drive and moves to the left, the cone voussoir 9 that moves axially of left side movement forces several voussoir 8 that moves radially to move radially along the rectangular window of guide cylinder cylinder 7 by inclined-plane, until with pile pipe contact internal walls, and have enough surface contact forces。This contact force should be greater than hung pile pipe weight and is multiplied by Hoisting Security coefficient after being multiplied by coefficient of friction。
Connecting the external diameter external diameter more than hung pile pipe of seat 5, limit the position of pipe hanger and pile pipe, the axial moving force of Hollow hydraulic cylinder 3 is delivered in pile pipe by connecting seat 5。When moving radially voussoir 8 mouthfuls and contacting with pile pipe, Hollow hydraulic cylinder 3 axial moving force is overcome by the footpath internal force of pile pipe。
