Shown in Fig. 7,8, be the another kind of piling apparatus structure in the top pressing type Static pressure pile driver, described piling cap 4 is provided with three piling oil cylinders 5, piling oil cylinder 5 is divided into two groups, wherein one group is adopted a bigger piling oil cylinder 5 to be arranged on the center of piling cap 4, and be connected in a sliding beam 9 below, the both sides of the big piling oil cylinder 5 of another group two less relatively piling oil cylinders 5 symmetrical distributions, and being separately positioned on below the sliding beam 9 of two correspondences.
In the utility model, the piling positioner also can adopt the structure of other form, the top pressing type structure of hydraulic pressure Static pressure pile driver of the prior art as described above, the basic structure of this device comprises: be arranged on a pair of rotating claw of both sides, sliding beam 9 top and the spring that links with claw, and be fixedly installed on the locational some corresponding bearing pins of the inboard differing heights of framework, activity screens thing wherein is a claw, fixedly the screens thing is a bearing pin, because therefore this structure is not described in detail in the utility model for existing patented technology.In addition, because the hydraulic control system that links with piling oil cylinder 5 is an existing product, therefore, in the utility model, this is not described specifically yet.
In the utility model, when this top pressing type Static pressure pile driver is used for pile foundation construction, earlier pile 3 is lifted in the framework 2, be arranged on piling cap 4 below, at this moment, be arranged on two in the framework 2 cover jack unit and sliding beam 9 thereof and all be positioned at high workload position, activity screens thing in the piling positioner also with framework 2 on the fixedly screens thing that is in the extreme higher position offset, then, start a cover hydraulic control system and drive the jack unit work that links with it, make the piston rod 6 of piling oil cylinder 5 protruding, at this moment, because the sliding beam 9 on the prepressing device temporarily is positioned on the sidewall of framework 2, therefore by the piling positioner, the counterweight of Static pressure pile driver and deadweight, just by bearing support 1, framework 2, the piling positioner, sliding beam 9, the conduction of piling oil cylinder 5 and piling cap 4 forms static pressure at the top of pile 3, along with the continuous increase of this static pressure, pile 3 just is pressed into underground, up to the piling stroke end of piling oil cylinder 5; After 5 one piling strokes of this piling oil cylinder finish, hydraulic control system just begins reverse drive piling oil cylinder 5, when constantly shrinking inwards along with piling oil cylinder 5 piston rods 6, sliding beam 9 in the prepressing device and piling positioner thereof, in its action of gravity, guide rail in framework 2 slides downwards together, when the piston rod 6 of piling oil cylinder 5 shrinks end, activity screens thing on the sliding beam 9 just once more by in the framework 2 the more fixedly screens thing on the lower position block, jack unit is prepared piling stroke next time, so far, the work period of a jack unit finishes.
Owing in top pressing type Static pressure pile driver of the present utility model, be provided with two cover jack units, therefore, in the piling process, use this two covers jack unit to replace piling and just can realize continuous construction.That is: when the startup first cover jack unit carries out piling, its piling oil cylinder 5 piston rods 6 are constantly protruding, and by piling cap 4 with pile 3 toward pressing down, at this moment, piling oil cylinder 5 piston rods 6 inside indentations in the second cover jack unit, this jack unit is also descending with piling cap 4 simultaneously, when the first cover jack unit piling finishes, activity screens thing in the second cover piling positioner just is positioned at the fixedly screens thing on the more lower position on the framework 2, so that this jack unit and piling positioner thereof perform the preparation of next round pressing pile construction; After the first cover jack unit piling finishes, it just repeats the piling set-up procedure of the above-mentioned second cover jack unit, hydraulic control system drives piling oil cylinder 5 piston rods 6 and shrinks inwards, the second cover jack unit is then taken over the jack unit of first cover, continue constantly to be pressed into above-mentioned pile 3 underground, at this moment, the first cover jack unit is also descending with piling cap 4, when the piling stroke of another set of jack unit finishes, the also attached more fixedly screens thing place of the lower position preparation screens fortunately of piling positioner wherein, this jack unit is also prepared the pressing pile construction of next stroke simultaneously.So move in circles, piling oil cylinder 5 piston rods 6 of two covers in the jack units are continuously done to replace stretching motion, continuously pile 3 is pressed into by piling cap 4 underground, thereby make this Static pressure pile driver realize continuous pressing pile construction.
In the utility model,, therefore, under the situation that increases less manufacturing cost, just realized double work efficiency nearly because the top pressing type Static pressure pile driver has increased by a cover jack unit and a hydraulic control system thereof; Simultaneously, in the pressing pile construction process of pile 3, bigger as ground to the resistance of pile 3, when the carrying of one cover jack unit can't be carried out piling, in this Static pressure pile driver two cover prepressing device also can adopt the way of synchronous pressing pile construction, increased the static pressure supporting capacity of this machine jack unit thus greatly, thereby made this Static pressure pile driver have stronger operating flexibility and reasonability.
In addition, Fig. 7, another kind of jack unit shown in 8, be provided with three piling oil cylinders 5 altogether in this device, the piston rod 6 that wherein is positioned at a piling oil cylinder 5 at piling cap 4 centers will be slightly slightly, and piston rod 6 outlines of two piling oil cylinders 5 that are positioned at its both sides are thin, use the Static pressure pile driver of this jack unit, its course of work is the same, and adopts less piling oil cylinder 5 can reduce manufacturing cost usually, and can simplify frame for movement, therefore, jack unit in the utility model generally all is being provided with three to four piling oil cylinders 5, certainly, also can adopt the piling oil cylinder 5 of greater number, but the corresponding raising of its cost meeting, and frame for movement is complicated.
In the utility model; be provided with the piling positioner between the framework 2 of top pressing type Static pressure pile driver and the jack unit; the basic structure of this positioner generally includes: fixedly screens thing and activity screens thing; as three kinds of structures having introduced among the above-mentioned embodiment; some groups fixedly the screens thing be fixedly installed on respectively on the differing heights in the framework 2; activity screens thing and each be screens thing corresponding matching fixedly; and be set on the sliding beam 9; this activity screens thing by with spring 18; cooperations such as deadweight; make sliding beam 9 in framework 2, realize unidirectional moving; be that common sliding beam 9 can not blocked by the piling positioner when descending, but if will upwards slide then and can be stuck.The top pressing type Static pressure pile driver just makes its static pressure pass to the top of pile 3 by the piling positioner just, and is pressed into pile 3 underground; Otherwise just cisco unity malfunction.In the utility model, this piling positioner can adopt other various ways, but its effect and function are all similar, at this, does not also remake one by one and describes.Generally being provided with wire rope 13 in above-mentioned piling positioner links with activity screens thing, wire rope 13 links by pulley 14 and elevator wheel 16, owing to must come back to high workload position when sliding into the minimum operating position of Static pressure pile driver under the jack unit, therefore, the effect of wire rope 13 mainly is that jack unit is mentioned easily, and make the indentation inwards in up process of activity screens thing, prevent to offset with fixing screens thing.
The utility model mainly is applicable to the Static pressure pile driver of top pressing type.
