As shown in Figure 5, balance arm 6 provides the peripheral operation platform for internal-expansion type being hung a device insertion pile tube.Balance arm 6 comprises: mainboard 64, the backplate 61 that is vertically mounted on mainboard 64 1 sides that is connected with barrel head 4, the riser 62 that is vertically mounted on mainboard 64 opposite sides, with 64 vertical connections of mainboard, and be vertically mounted on the transverse slat 63 on the riser 62; Wherein, mainboard 64 is provided with the U type groove that matches with the arc sections of barrel head 4, and mainboard 64 is provided with several suspension centre holes; The both sides of the mainboard 64 of present embodiment have tapped bore, and mainboard 64 is connected through bolt connecting mode and barrel head 4, have several circular holes on the riser 64 of balance arm 6, for assurance level lifting internal-expansion type hangs the suspension centre that a device provides hoisting crane.
One ring baffle 5 is installed between balance arm 6 and cylindrical drum 7, and ring baffle 5 adopts bolt connecting modes to be connected on the barrel head 4, and ring baffle 5 is used for limiting and hangs the depth that a device inserts pile tube.Stretch into any degree of depth in the pile tube for fear of hanging a device, must guarantee ring baffle 5 and pipe pile end portion applying.
As shown in Figure 6, guide cone 9 general shapes are a pyramidal structure, provide convenience for internal-expansion type hangs a device insertion pile tube.Guide cone 9 comprises: end casing 91, adopt welding manners riser 94 connected vertically with end casing 91; Adopt welding manner to be vertically connected on the reinforced rib 92 between end casing 91 and the riser 94; Wherein, riser 94 is provided with confession links to each other hydraulic cylinder piston rod 27 with guide cone 9 installation pin-and-hole 93.Utilize hinged fork 95 and bearing pin 96 that hydraulic cylinder rod 27 and guide cone 9 are linked, for the power of hydraulic cylinder rod 27 provides a fulcrum.
The principle of work that internal-expansion type of the present invention hangs a device is:
The actuator that the present invention adopts is a hydraulic actuating cylinder 26, and utilizes to be located at and drive cone 2 in-to-in hydraulic actuating cylinders 26, according to relative motion principle, makes to drive cone 2 and relatively move with frame.Then, through oblique mechanism, carry out the amplification of power and the transformation of direction, limiting the outer piece 8 that expands through cylindrical drum 7 windows can only expand radially outward or shrink, final, realizes clamping and the work of loosening the pile tube inwall.
During use:
1. through the hydraulic power source fuel feeding, make the outer piece 8 that expands of the present invention be in complete contraction state, under the lifting effect of crane, to be inserted into the pile tube of horizontal positioned inner with hanging a device along continuous straight runs through the lifting hole(eyelet) on balance arm 6 risers 62.The taper outer form of guide cone 9 is promptly: in order to make suspender be easier to inserting the time ratio.5 of ring baffles are to be used to limit the position relation of hanging a device and pile tube, because the external diameter of ring baffle 5 is greater than the external diameter of pile tube, thereby, make that hanging a device is unlikely to stretch in the pile tube degree of depth arbitrarily, fits as long as guarantee ring baffle 5 and pipe pile end portion.
2. to driving hydraulic actuating cylinder 26 fuel feeding of cone 2; Make that the piston rod of hydraulic actuating cylinder 26 is overhanging; Because the top and the guide cone 9 of piston rod connect firmly together through hinged fork, according to relative motion principle, 2 of whole driving cones along axis direction to a lateral movement away from guide cone 9.Like this, through driving the oblique mechanism of cone 2 and 81 of slide blocks, outer bloated piece 8 parts formed of briquetting, slide block 81 then, that is: from bloated at home and abroad the stretching out of window of cylindrical drum 7, thereby, make briquetting and pile tube inwall press together.
3. this moment, the suspension centre of crane is placed in the shackle 28, shackle 28 is finally lifted by crane plumbness with pile tube through the internal-expansion type suspender thereby promote shackle 28 with to drive cone 2 hangers 22 hinged.At this moment, the state of internal-expansion type suspender is: the vertical state shown in Fig. 1 b.Like this, crane is pulled away from ground with pile tube and moves promptly: realized pile tube spatial displacement and operation.
4. after pile tube being placed on assigned address; Loosen the lifting rope of hoisting crane; By hydraulic actuating cylinder 26 reverse fuel feeding, thereby make hydraulic cylinder rod 27 reclaim, drive cone 2 relative cylindrical drum 7 and frame and move down; T type key bar 83 through driving on the cone 2 drives slide block 81 and the whole outer piece 8 parts retraction that expands, and makes internal-expansion type hang a device and no longer contacts with the pile tube inwall.
5. adopt weight-lifting equipment will hang a device and from pile tube, pull out, reach unloading order ground.
The advantage that internal-expansion type of the present invention hangs a device is:
1. in design, adopt a hydraulic actuating cylinder 26 to control the motion of the piece 8 that expands outside 8 simultaneously, have reasonable in design, reduce number of components, easy advantage system's control.
2. owing to can increase the cushion block of some, make the adaptation caliber scope of suspender increase, can realize a tractor serves several purposes.
3. owing to used oblique mechanism, the system that makes has boosting function, therefore, has saved the required power that provides of hydraulic actuating cylinder 26, has reduced the requirement to hydraulic actuating cylinder 26.
4. during owing to lifting, driving cone 2 is a kind of form of inverted triangle, has guaranteed lifting back pile tube dependence gravity self-locking, and pile tube is safety aloft.
The above; It only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
