Described upward ring beam and lower ring are to adopt four sections combining structures, and every section is quarter turn, and links by bolt between every section circumference ring beam.
Described plugging pin oil cylinder is positioned at the middle part of every section circumference ring beam.
The two ends of described every section circumference ring beam are connected to hoist cylinder respectively.
Pin-and-hole in the described shoe is the mode that adopts four row evenly to arrange.
The present invention is after having adopted such scheme, and its great advantage is the lower ring structure design, utilizes finite element stress analysis, the ring beam structure is optimized, as far as possible simplified structure, reduce construction weight.For ease of the transportation assembling, ring beam is 4 sections combining structures, and every section quarter turn links to each other with bolt.In the middle of every section 1/4 ring beam is hydraulic bolt, can insert the pin-and-hole on the dress leg, and two ends are hoist cylinder.In a word, the present invention have good security performance, transmission freely, advantage such as simple in structure, easy to operate, in light weight.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
Fig. 2 is the overall structure schematic diagram of ring beam formula hydraulic lifting apparatus of the present invention.
The specific embodiment
The invention will be further described below in conjunction with institute's drawings attached, preferred embodiment of the present invention is: the described a kind of jacking equipment that is used for ship of present embodiment, it includes shoe 1, tower 2, ring beam formula hydraulic lifting apparatus 3, hull 4 is installed, wherein, shoe 1 of the present invention is positioned at ring beam formula hydraulic lifting apparatus 3, and shoe 1 is provided with the pin-and-hole that four row are evenly arranged, be used for matching, and then shoe 1 of the present invention is linked by plugging pin oil cylinder 7 and ring beam formula hydraulic lifting apparatus 3 with plugging pin oil cylinder 7 on the ring beam formula hydraulic lifting apparatus 3; Tower 2 is installed fixedly to link with hull 4; Ring beam formula hydraulic lifting apparatus 3 links with tower 2 is installed by cushion, and ring beam formula hydraulic lifting apparatus 3 is being installed between tower 2 and the hull 4; And ring beam formula hydraulic lifting apparatus 3 of the present invention includes ring beam 5, connecting pin 6, plugging pin oil cylinder 7, hoist cylinder 8, lower ring 9, wherein, hoist cylinder 8 is between last ring beam 5 and lower ring 9, and hoist cylinder 8 links with last ring beam 5 and lower ring 9 respectively by connecting pin 6; Plugging pin oil cylinder 7 is assemblied in ring beam 5 and the lower ring 9.Wherein, for the ease of the transportation assembling, upward ring beam 5 of the present invention and lower ring 9 are to adopt four sections combining structures, every section is quarter turn, and link by bolt between every section circumference ring beam, and plugging pin oil cylinder 7 is positioned at the middle part of every section circumference ring beam, can insert the pin-and-hole on the spud leg, and the two ends of every section circumference ring beam are connected to hoist cylinder 8 respectively.The present invention provides power source by Hydraulic Station, by hydraulic system operation hoist cylinder 8 and plugging pin oil cylinder 7 ring beam 5 and lower ring 9 is fixed with hull.During work, when the present invention will rise shoe 1, hoist cylinder 8 was in piston rod emersion state.After the plugging pin oil cylinder 7 of lower ring 9 is inserted the stake pin with latch, hoist cylinder 8 rises shoe 1 is extracted, to go up the plugging pin oil cylinder 7 of ring beam 5 with latch insertion stake pin after reaching stroke, lower ring 9 gets plugging pin oil cylinder 7 latch is extracted the stake pin, hoist cylinder 8 drops to lower ring 9, the plugging pin oil cylinder 7 of lower ring 9 is inserted next stake pin with latch, so repeatedly.And when the present invention will descend shoe, hoist cylinder 8 was in the piston rod retracted mode.After the plugging pin oil cylinder 7 of lower ring 9 is inserted the stake pin with latch, 8 times general who has surrendered's shoes of hoist cylinder 1 are sunk, to go up the plugging pin oil cylinder 7 of ring beam 5 with latch insertion stake pin after reaching stroke, the plugging pin oil cylinder 7 of lower ring 9 is extracted the stake pin with latch, hoist cylinder 8 rises to lower ring 9, the plugging pin oil cylinder 7 of lower ring 9 is inserted next stake pin with latch, so repeatedly.Above duty hydraulic system is under the rated operating pressure, and the present invention also has the function of piling in addition, and this moment, hydraulic system was under the maximum working pressure (MWP).When piling of the present invention, after hull arrives the assigned work position, two shoes 1 of diagonal position are risen to the disengaging seabed, last ring beam 5 latches are extracted shoe 1, lower ring 9 latches insert shoe 1, hydraulic system pressure is risen to maximum worker's pressure, and hoist cylinder 8 back cavity work, shoe 1 this moment produce downward power and are about heavy two times of ship; To break away from two shoes in seabed 1 and descend, two shoes 1 of two of pilings rise to and break away from the seabed, repeat the piling process again.In a word, the lower ring structure design that goes up of the present invention is utilized finite element stress analysis, the ring beam structure is optimized, as far as possible simplified structure, reduce construction weight.And the present invention also have good security performance, transmission freely, advantage such as simple in structure, easy to operate, in light weight.Therefore, the present invention can solve the problems that traditional in the past jacking equipment that is used for ship exists preferably, is worthy to be popularized.
The embodiment of the above only is the present invention's preferred embodiment, is not to limit practical range of the present invention with this, so the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
