Abstract
The invention discloses a gauge pile hydraulic lifting device compact in structure. The gauge pile hydraulic lifting device comprises an upper ring beam and a lower ring beam which are connected with a gauge pile, and a lifting oil cylinder is arranged between the upper ring beam and the lower ring beam; the lifting oil cylinder is connected with the upper ring beam and the lower ring beam through an oil cylinder hinge, and bolts are matched with a bolt hole on the gauge pile; the lower ring beam is connected with a hinged support firmly welded to a deck through a hinge; self-lubricating joint bearings are installed in an upper hinge point and a lower hinge point of the hinge so that the hinge can swing, and imbalance caused by factors such as the slant gauge pile and ship deformation can be compensated; the bolt on the lower ring beam is a supporting bolt, a bolt on the upper ring beam is a working bolt; and during working, at least one set of the bolts of the upper ring beam and the lower ring beam must be located in the bolt hole, and therefore safety is guaranteed. The gauge pile hydraulic lifting device is reasonable in structure and good in working performance. The bolts on the upper ring beam and the lower ring beam are inserted into an insertion hole on the gauge pile in turns, the gauge pile is lifted and put down by stretching out and retracting back of a hydraulic oil cylinder piston rod, and meanwhile a ship body can ascend and descend.
Description
Technical field
The present invention relates to a kind of work pile hydraulic lift.
Background technology
Work pile is applied on the dredgers such as strand suction, grab bucket, backhoe, and Main Function is location.By hydraulic cylinder jacking pulley on cutter suction dredger, hold promote work pile around the Eight characters hawser on work pile with steel rope, work pile falls then by its deadweight.On grab bucket, backhoe dredger, work pile winch (hydraulic pressure or driven by power) is elevated by wire rope pulley, also useful pinion and rack is elevated, except location lifts ship piling function in addition, hull is made to reduce drinking water, thus increase the vertical load of work pile, play and stablize hull when operation, reduce the effect swung.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, favorable working performance, constructs compact work pile hydraulic lift.
Technical solution of the present invention is:
A kind ofly construct compact work pile hydraulic lift, it is characterized in that: comprise the upper and lower ring beam be connected with location pile body, arrange hoist cylinder between upper and lower ring beam, and hoist cylinder is connected with upper and lower ring beam by oil cylinder hinged shaft, latch coordinates with the pin hole on work pile; Lower ring hinge is connected with the free bearing welded above deck; In the upper and lower hinge of hinge, self-lubricating knuckle bearing is housed, hinge is swung, can compensate and be tilted by work pile and overbalance that the factor such as shipbody deformation causes; Latch on lower ring is for supporting latch, and the latch on upper ring beam is working latch, and during operation, the latch on upper and lower ring beam must have one group all the time in pin hole; Ring beam CCSH36 high strength low alloy steel plate is welded into box-structure.
Pin hole spacing is 0.6-1.2m.
