Abstract
The invention discloses a hydraulic lifting device with a reasonable structure and for a positioning pile. The hydraulic lifting device comprises an upper ring beam and a lower ring beam which are connected with a positioning pile body, wherein a lifting oil cylinder is arranged between the upper ring beam and the lower ring beam and connected with the upper ring beam and the lower ring beam through oil cylinder hinge shafts, and plugs are matched with plug holes in the positioning pile; the lower ring beam is connected with hinging seats firmly welded on a deck through hinges, self-lubrication spherical plain bearings are mounted in the upper hinge points and the lower hinge points of the hinges, so that the hinges can swing, and unbalance caused by factors such as the obliquity of the positioning pile and the deformation of a ship body can be compensated; the plugs on the lower ring beam are supporting plugs, the plugs on the upper ring beam are operational plugs, and during operation, a group of the plugs on the upper ring beam and the lower ring beam needs to be in the plug holes all the time so as to ensure the security. The hydraulic lifting device disclosed by the invention is reasonable in structure and good in operational properties, the plugs on the upper ring beam and the lower ring beam are inserted into inserting holes in the positioning pile in turn, the lifting and the lowering of the positioning pile are completed through the extension and the contraction of a hydraulic oil cylinder piston rod, and besides the lifting and the lowering of the ship body can be realized.
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, the work pile hydraulic lift rational in infrastructure of favorable working performance.
Technical solution of the present invention is:
A kind of work pile hydraulic lift rational in infrastructure, 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; Lower ring M30 high strength bolt is connected with the multiple base on chassis end face, by a small amount of pendulum motion compensation of chassis.
Pin hole spacing is 0.6-1.2m.
