Description
The utility model relates to a kind of building machinery, and the hydraulic-driven rope on particularly a kind of pile press is pulled on into a roof pressure and pressed and pull out mechanism.
Common static pile press is made piling power in electronic elevator mode.This kind mode is advanced stake difficulty, troublesome poeration; Its pile cutoff is filled in pile cutoff with crane gear normally when the piling beam rises to a high position from the bottom of piling beam, therefore exist pile cutoff and hang in and very inconvenient defect in place, and work efficiency is low and dangerous; Common clipping hydraulic pressure pile press then can only be constructed to the pile cutoff of square-section, and higher to pile cutoff self requirement of strength, and the piling ability should not be to big specification development because of being subjected to the restriction of clamping frictional force very limited.
The purpose of this utility model is: improve the disadvantage that exists in the aforementioned prior art, provide a kind of with hydraulic actuation power, the pile cutoff hoisted in position is convenient and have hydraulic-driven rope on the pile press of pile pulling function and pull on into a roof pressure and press and pull out mechanism's structure.
Mechanism described in the utility model is by piling drive unit hydraulic jack (13), portal frame (1 4) wire rope group (15), downslide wheels (16), press pile pulling beam (17), equalizer pulley group (172), on draw wire rope group (18), it beam assembly pulley (19), a day beam (20) is formed.Its architectural feature is: four hydraulic jacks (13) are installed in respectively in four portal frames (14), the piston club head of hydraulic jack (13) and body (10) are hinged, its cylinder body can slide up and down along the guide rail in the portal frame (14) up, wire rope group (15) is walked around on the semicircle grooving that downslide wheels (16) are enclosed within hydraulic jack (13) cylinder body bottom through equalizer pulley group (172), on draw wire rope group (18) to prick on the earrings on hydraulic jack (13) cylinder body top by sky beam assembly pulley (19) bolt on day beam (20) through pressing the hanger on the pile pulling beam (17).
Pressing pile pulling beam (17) is that pile element is advanced on a kind of specially designed top in the described mechanism.The steel work T type main body (171) of perforate in the middle of it has one, equalizer pulley group (172) is housed on it, tapping has a slip dodge gate (173) by switch hydraulic jack (174) control in the middle of it, and a pile cutoff spider (176) is arranged under the slip dodge gate (173); T type main body (171) go up to also have an overlength pile cover (175), connects with wire rope group (177) between overlength pile cover (175) and T type main body (171).
When the piling operation begins, will press pile pulling beam (17) to place minimum operating position, hydraulic control system makes switch hydraulic jack (174) work, slip dodge gate (173) is opened perforate in the middle of exposing.This moment, crane gear placed the hole with pile cutoff by perforate top in the middle of the T type main body (171) of pressing pile pulling beam (17), and pile cutoff places ground construction stake position by perforate and pile cutoff spider (176).At this moment, control system makes hydraulic jack (13) rod chamber work, and cylinder body promptly moves down, hydraulic jack (13) backhaul.Cylinder body was pricked by bolt and was drawn wire rope group (18) will press pile pulling beam (17) to be pulled upwardly till the pile cutoff top is lower than slip dodge gate (173) lower edge on its top this moment.Console switch hydraulic jack (174) is closed slip dodge gate (173), and the geometry that utilizes other institutional adjustment pile cutoff on the pile press then makes it to be the state that can be pressed into for putting.Operating hydraulically operated oil cylinder (13) makes its rodless cavity work, then cylinder body rises, hydraulic jack (13) lift, the semicircle grooving of cylinder body lower end by walking around downslide wheels (16) wire rope group (15) and through being contained in the transmission of pressing the equalizer pulley group (172) on the pile pulling beam (17), to press pile pulling beam (17) pulling downwards, pile driving pressure just acts on the pile cutoff top by slip dodge gate (173) bottom, make pile cutoff steadily sink to ending until hydraulic jack (13) impulse stroke, press pile pulling beam (17) to come back to minimum operating position, a piling working cycles is promptly accused and is finished in this way.Repeat said process and be aided with aided process such as pile cutoff joint connection, then pile cutoff can be pressed into up to meeting design requirement by joint.
When pile cutoff length surpasses pile press design standard stroke, can use overlength pile cover (175).The overlength pile cutoff inserted press in the middle perforate that pile pulling beam (17) opens, with crane gear overlength pile cover (175) is sling and to be buckled in the pile cutoff top, operating hydraulically operated oil cylinder (13) makes its rodless cavity work, the piling process as described above of getting final product is the same, make and press pile pulling beam (17) descending, be delivered to pile driving pressure overlength pile cover (175) and by it act on pile cutoff top by wire rope group (177) this moment, and pile cutoff is sunk.When pile cutoff when above ground portion is pressed into length less than standard, can use and press pile pulling beam (17) that it directly is pressed into.
So, mechanism described in the utility model has just had stake easily,, easy to operate advantage; Low level advances stake, and pile cutoff hangs in in place very convenient, and pile cutoff buries to connect and is used to steady safety; In addition, the pressure pile pulling mechanism of its uniqueness makes its applicable surface broad, can satisfy various different materials, the construction requirement of the shaping pile cutoff of different cross section shape, even huge pile pulling power can be provided, carry out pulling out the operation of pressure pipe castinplace pile steel pipe and super long pile such as pressure.

Below introduce embodiment.
Because pile cutoff is longer, the hydraulic jack stroke is limited, so the hydraulic jack (13) that described mechanism adopts is a kind of special multistage hydraulic cylinder.In each circulation of piling process, the hydraulic cylinder of multistage hydraulic cylinder innermost layer (being that piston area is less) stretches out earlier, and this moment, the stratum was softer, and penetrating resistance is little, and pile sinking speed is very fast.Cover stretches out behind the hydraulic cylinder of (being that piston area is bigger) outside, and this moment, the stratum was harder, and penetrating resistance is big, and pile sinking speed is slower, so just can fully adapt to and satisfy the requirement of pressing pile construction technology, can make full use of the power of pile press simultaneously again.
In order to satisfy needs easy to maintenance and simple to operate, also hydraulic jack (13) can be designed to stroke is 1/2nd of aforementioned multistage cylinder total kilometres, and piston area is the single-stage double-act-ing hydraulic J-Horner of the twice of aforementioned multistage cylinder maximum area.This moment should with steel wire group (15) and on to draw steel wire group (18) to change the speedup multiplying power into be two times speedup assembly pulley, change the semicircle grooving of hydraulic jack (13) cylinder body lower end into pulley, draw the earrings of steel wire group (18) also to change pulley on the bolt bundle of cylinder body upper end.The fag end bolt of steel wire group (15) is pricked on body (10), on draw the fag end bolt of steel wire group (18) to prick on Tian Liang (20).Identical when the operating principle of piling mechanism and aforementioned multistage cylinder drive, the piling ability is also just the same.
In addition, as the another kind of form of hydraulic pressure stake drive unit, the hydraulic winch (24) with four fluid motor-driven can be come replacement liquid compressing cylinder (13) make the piling drive unit.Need only do some changes (as shown in Figure 7) around mode with wearing of wire rope group and get final product this moment.Its operating principle is not given unnecessary details with to make the piling drive unit with aforementioned hydraulic oil cylinder (13) similar herein
