Abstract
The utility model provides a corner and side pile driving mechanism, and is one of operation mechanisms of hydraulic static pipe driver, with a key role in providing a pile driving force and guiding the pile locking box. Flanges and screw bolts are adopted to connect the pile driving pillar, the machine body and the fixing seat on the weight counterbalance beam of the mechanism; by arranging the pillar fixing seats on the two sides at the tail end of the machine body and the weight counterbalance beam, the pile driving mechanism can be positioned on the corner of the pile driver with the maximum operating boundary dimension; the distance of the corner and side pile is small, wherein the smallest distance of the corner pile is 0.45m. The weight counterbalance beam is designed as a reducing mechanism and prolonged to be the support of the pillar fixing seat. The weight counterbalance beam and a support foot cross beam are joined with a hinge, during the process of corner and side pile driving, the foot support bears the self weight of the pile driver and the balance weight, as well as the pile driving reaction force transferred by the weight counterbalance beam, so as to reduce the acting force upon the foot support. The pillar is designed into two pieces, that is a left one and a right one, which are in pin connection with a connecting pin through a connecting plate, so that the deformation stress upon the pillar caused by the deformation of the weight counterbalance beam can be removed effectively. The utility model has the advantages of simple structure and convenient use and maintenance, improves the ability of the static pile driver to treat the corner and side pile, and at the same time extends the sphere of application of the static pile driver as well.
Description
Affiliated technical field
The utility model relates to a kind of novel arm of angle stake piling mechanism of hydraulic static pile pressing machine.
Background technology
Hydraulic static pile pressing machine is the desirable stake construction equipment of preformed pile static pressure worker method, is widely used in the pile foundation engineering constructions such as precast square pile, pile tube and H type abnormal shape piling bar.Hydraulic static pile pressing machine piling mechanism is the key job mechanism of this machine, for various stake provides reliably, enough big chucking powers, for Pile holding mechanism provides enough big pile driving pressure, preformed pile is pressed into ground.At present, hydraulic static pile pressing machine piling mechanism treatable stake position is divided into: meta stake and skirt piles, and the ability of handling the meta stake is stronger, handle the ability of skirt piles and take second place, the ability of processing angle stake all is with the processing angle stake of skirt piles mechanism, the distance of processing angle stake is bigger, and minimum distance is greater than 1.2m.Along with reconstruction of the old city town, build to drop into strengthen, the ability of static pile press processing angle skirt piles has been proposed new requirement.
Summary of the invention
In order to overcome the processing angle stake of piling mechanism and the skirt piles ability of existing hydraulic static pile pressing machine, the angle pilespacing is from big deficiency, the utility model provides a kind of novel arm of angle stake piling mechanism, this arm of angle stake piling mechanism is made up of pile clamping box, column, piling oil cylinder, pile clamping box is passed to stake with the pile holder jail and with the pressure of piling oil cylinder, and stake is pressed into ground.The column of this mechanism bears pressure pile reaction, and be that pile clamping box leads, this column is a kind of pin connected construction, adopt flange bolt to flexibly connect with fuselage, when need processing angle skirt piles, pile clamping box is pulled down, then the connecting bolt of column and fuselage is dismantled, column is hung on the holder on the fuselage angle, use bolt.The holder of the column of this arm of angle stake processing mechanism adopts unique design, the counterweight beam is strengthened, and it is hinged with stake machine supporting leg, on the counterweight beam, load onto the column holder with the afterbody both sides, pressure pile standard is installed on this arm of angle stake seat, can handle the stake of the small distance arm of angle, this mechanism's processing angle skirt piles ability is strong, and minimum range can reach 0.45m, pile driving pressure can reach 70% of meta stake, column adopts pin connected construction, and the elastic deformation of energy collocation structure is eliminated the stress that distortion causes, this arm of angle stake piling reliable operation, simple in structure, use, easy to maintenance, long service life.
The technical scheme that its technical problem that solves the utility model adopts is: this arm of angle stake piling mechanism is made up of pile clamping box, column, piling oil cylinder, column holder, this column is connected the employing flange bolt and flexibly connects with fuselage, this connection advantage is that meta stake and arm of angle stake pressure pile standard can be shared, save cost, can also pull down column in the transportation, reduce shipping height.This column by about two half columns form, left and right pillar adopts pin to connect, the advantage of this connection is when the processing angle skirt piles, column is fixed on the column holder of being made up of counterweight beam and afterbody, the counterweight beam has certain deformation, this pin connects the distortion of column energy self adaptation counterweight beam, eliminates the stress that distortion causes.In order to improve the ability of processing angle skirt piles, especially the ability of angle stake, reduce the distance of angle stake, must be on the angle of stake machine with arm of angle mechanism design, because the two long outboard limit sizes of space are greater than the lateral dimension of fuselage during the work of stake machine, so long ship increases the distance of angle stake, arm of angle stake mechanism can not be completely fixed on the fuselage, on the maximum sized angle in the time of must adopting a kind of new design to make arm of angle stake mechanism be in a machine to work.For this reason that supporting leg crossbeam oil cylinder is outer part lengthening is fixed on the counterweight beam on the crossbeam of lengthening, and the influence of long ship diagonal angle stake lateral separation has been avoided in the outside of long ship in counterweight beam assembling back.Make it concordant counterweight beam lengthening with afterbody, the counterweight beam is designed to the reducing beam to strengthen intensity, with the holder design of the column of arm of angle stake piling mechanism on counterweight beam and afterbody, reduce the distance of vertical and horizontal both direction, make and press the distance of angle stake skirt piles to dwindle, processing angle stake minimum range is 0.45m, has improved the ability of processing angle skirt piles.
The beneficial effects of the utility model are, have reduced the distance that hydraulic static pile pressing machine is pressed arm of angle stake, have improved the ability of processing angle skirt piles, and stake minimum range in angle can reach 0.45m; Counterweight can be near piling mechanism in this mechanism, and stake pile driving pressure in angle can reach 70% of meta stake; Column adopts pin connected construction, and the elastic deformation of energy collocation structure is eliminated the stress that distortion causes; Column and holder adopt being connected of flange bolt activity, arm of angle stake and meta stake can be shared piling mechanism, save cost, convenient transportation.
