The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is done further detailed description.
As shown in figures 1 and 3, anti-pull-type impact pile sinking machine of the present invention comprises a jump bit 1, a tension and compression case 3, four pull bars 4, pile cover 5, quadruplet pull bar clamp mechanism and a cover external power supply (not shown).Wherein, jump bit 1 is positioned at the top of tension and compression case 3, and jump bit 1 and tension and compression case 3 are equipped with the coaxial centre bore that passes freely through for preformed pile 7, and external power supply is connected to drive jump bit with jump bit 1 and implements to impact.Pile cover 5 is positioned at the top of jump bit 1, and quadruplet pull bar clamp mechanism is evenly distributed on the inside of pile cover 5, and the corresponding pull bar 4 of every cover pull bar clamp mechanism is used for clamping and unclamping corresponding pull bar.The lower end of pull bar 4 and tension and compression case 3 are affixed, and the upper end of pull bar 4 is passed pile cover 5 and is fixedly connected with pile cover 5 adjustable grounds by corresponding pull bar clamp mechanism.
The part between jump bit 1 and tension and compression case 3 at preformed pile 7 is arranged with cushion pad 2, and this cushion pad is such as adopting the very large spring of rigidity.Be used on the one hand the shock absorbing hammer to the impact of tension and compression case, play the effect of protection tension and compression case, can also reduce on the other hand the noise that produces when jump bit impacts the tension and compression case.
Stake top at preformed pile 7 is provided with dolly 6.Certainly, this dolly 6 also can be located at the soffit of pile cover 5 and allow dolly 6 and the stake top of preformed pile 7 mutually align.Dolly is used for the buffering pile cover to the impact on preformed pile stake top, with protection stake top, avoids its cracking.This dolly can be selected the larger spring of rigidity, other elastomeric materials.
Fig. 2 is the cross sectional view of pile cover of the present invention.Shown in Fig. 2-3, pile cover 5 of the present invention is symmetrical decussate texture, and it has four symmetrical branches.See Fig. 2 for details, the middle part of each branch offers a through hole that supplies corresponding pull bar to pass, in each branch, offer two uncovered in the same way horizontal parallel gathering sills 14 in the both sides of through hole, offer two grooves 15 in opposite directions in the middle part of two gathering sills 14 vertical direction, each groove 15 connects with corresponding through hole and gathering sill 14.
As shown in Figure 2, in each branch of pile cover 5, be provided with a cover pull bar clamp mechanism.Every cover pull bar clamp mechanism comprises: be sub-packed in two V word pins 9 in two gathering sills 14, be divided into slidably two tapered wedges 8 in two grooves 15, be installed in two oil cylinders 13 in this branch, and two cover connect respectively the connecting rod crank mechanism of homonymy V word pin 9 and oil cylinder 13, i.e. connecting rod 11 and crank 12.
As shown in Figure 2, the tail end of V word pin 9 is equipped with back-moving spring 10, is used for V word pin 9 is resetted.The front end of V word pin 9 links to each other with connecting rod 11, connecting rod 11 links to each other with oil cylinder 13 by crank 12 again, crank 12 is driven (as shown by arrows in FIG.) by oil cylinder 13, thereby V word pin 9, connecting rod 11 and crank 12 consist of a slider-crank mechanism, and V word pin 9 can be in gathering sill 14 interior slips under the effect of connecting rod 11.And the tail end of V word pin 9 is large, and front end is little.
As shown in figures 1 and 3, the top of every pull bar 4 is installed with a plurality of up big and down small frustums 16.
Referring to Fig. 1-2, in same branch, when the piston rod of two oil cylinders 13 stretches out, two V word pins 9 are pulled outwardly out, their tail end compresses respectively two tapered wedges 8 simultaneously, at this moment two relative tapered wedges 8 stretch into centre bore and form the diclinic wedge surfaces and cooperates with frustum 16 on the pull bar 4, thereby so that the pull bar clamp mechanism clamps pull bar, the back-moving spring 10 of V word pin 9 tail ends is stretched at this moment.And after oil cylinder 13 quit work, back-moving spring 10 resetted and spurs V word pin 9 and retreat, and their front end contacts respectively two tapered wedges 8 simultaneously, and at this moment two relative tapered wedges 8 are retracted from centre bore, thereby so that the pull bar clamp mechanism pull bar is unclamped.Like this, the height of adjusting yoke easily just of the pull bar clamp mechanism by diclinic wedge surface form.
Certainly, pile cover also can be symmetrical herringbone or pentagon, and it has three or five symmetrical branches.Accordingly, described pull bar is provided with three or five, and they are fixed on the tension and compression case, and be distributed on preformed pile around, be arranged in juxtaposition with preformed pile.Preferably, these pull bars are cylindrical bar.A plurality of holes that also can evenly distribute on the tension and compression case are for cylinder lever connecting rod.
Jump bit 1 is cylinder, and tension and compression case 3 is disc, preferably is foundry goods.
The operating principle of anti-pull-type impact pile sinking machine of the present invention is: after pull bar is clamped, jump bit impacts the tension and compression case, the pulling force that impact to produce is passed on the pile cover by the pull bar that is connected with tension and compression case two ends, and the pulling pile cover moves downward driven precast pile, and preformed pile is sunk in the rock.
The course of work of the present invention is divided into two stages:
Phase I is assault phase: 12 motions of oil cylinder 13 driving cranks, and pulling V word pin 9 makes the tail end of V word pin 9 compress tapered wedges 8, and tapered wedges 8 contacts with the frustum 16 of pull bar 4 and forms the diclinic wedge surface, thereby clamps pull bar 4.Then, according to the Specific construction situation, regulate the shock height of jump bit 1, jump bit 1 is moved downward with certain acceleration to be hit on tension and compression case 3, hit the power pulse that produces and be passed on the pile cover 5 by pull bar 4, thereby pulling pile cover 5 moves downward driven precast pile 7, realizes pile sinking.
Second stage is the pull bar adjusting stage: after pile sinking finished, the height of preformed pile 7 reduced, and the length of pull bar 4 need to readjust.At this moment, oil cylinder 13 quits work, and the back-moving spring 10 pulling V word pin 9 that resets retreats the front end in contact tapered wedges 8 of V word pin 9, clamp mechanism releasing lever 4.After readjusting the height of pull bar 4, oil cylinder 13 is driving crank 12 pulling V word pins 9 chucking tapered wedges 8 again, again clamp pull bar 4, for impacting ready next time.
Anti-pull-type impact pile sinking machine of the present invention has not only improved impact energy, has reduced the pile frame height significantly, and has effectively protected the stake top of preformed pile.
Although preferred embodiment of the present invention is described in detail and illustrates, the present invention is not limited thereto.Should be known in that those skilled in the art can carry out numerous modifications and variations under the condition that does not deviate from spirit of the present invention and principle, and do not break away from protection scope of the present invention that it is limited by claims.
