Abstract
The invention discloses a sliding track vehicle for dragging and launching a drilling ship. Roller wheels (4) are arranged at the bottom of a pulley (8), a hydraulic cylinder (5) is vertically arranged on the upper part of the pulley (8), and a piston (6) is arranged on the hydraulic cylinder (5). The sliding track vehicle, which is arranged on a track, shares the weight of the drilling ship, and the drilling ship is conveniently dragged and launched, so that the cost of a large ocean engineering drilling platform is reduced, a drilling platform ship is safely and steadily dragged and launched or semi-submerged, and the sliding track vehicle has the advantages of small construction amount, short construction time, low investment, high construction reliability and high generality; the cost of supporting facilities is reduced accordingly; the sliding track vehicle belongs to extremely-flexible carrying and launching technologies, has the remarkable advantages of labor conservation, time conservation, effortlessness, investment conservation, flexibility, safety, reliability, good comprehensive economic benefit and the like, and has a popularization value; the manufacturing cost of an ocean drilling platform is reduced.
Description
Technical field
The apparatus, the especially drilling ship that the present invention relates to water, hauling-out or dry-docking under extra large work and ship-related products construction applications ship drag lower water track sled.
Background technology
Launching is that boats and ships are built after basic completion at building berth, and boats and ships are moved on to the technological process waters from build area, is an important step in ship building process, is also the process procedure of more complicated.The factor that affects launching safety is a lot, and interim fabrication yard need to be set in engineering construction place, adopts simple, convenient, inexpensive lower drainage facility assisting as necessity.
Drilling ship is different from conventional shipping boats and ships, and it belongs to a kind of auxiliary vessel, and the average weight of unit volume is much larger than conventional ship.Such as its principal dimensions is 210 meters of overall lengths, 34 meters of molded breadths, 17.5 meters of moldeed depth, and weight is had an appointment 29000 tons, is approximately 3 times of the conventional ship weight of same size.Equipment and process mode for water under large-scale ocean engineering drilling platform, common are following several: 1) water under runway: first drilling platform is guided to and in oblique unwheeling, locate and fix it, then by winch, discharge steel cable, drilling platform is fallen in water together with oblique unwheeling, boats and ships can be under self buoyancy floating voluntarily, the method need to be built the launching way that reaches more than 100 meter in advance, and corresponding deep channel, the oblique specialized equipment such as unwheeling.Invest highly, the construction time is long, and launching way cannot reclaim.2) air bag launching: utilize high-pressure aerated rubber pneumatic bag to bear boats and ships deadweight, rolling distortion by air bag and boats and ships deadweight make new shipbuilding oceangoing ship descend smoothly water in conjunction with the gradient in soil, but it is uneven that air bag easily produces cyst wall internal pressure, easily produce delamination foaming phenomenon, even occur the danger of unexpected explosion.And also there is shortage theory support in air bag launching mode, the problem such as lack of standardization in practical operation.3) lower water in depressed place: under Large Ship Dock, water is generally comprised of dock bottom, wing wall, pump plant.During lower water, first water is injected to dock, boats and ships rely on buoyancy force, when the water surface has been put down inside and outside depressed place, open dock gate, and ship is outputed to dock.Though drainage facility has the ability that can dock with many accommodations horizontal building berth under floating dock, operation is complicated, in the time of most, will be equipped with deep water sinkage dock pit.In a word, above method all can not form the equipment and process method of water under large ship with shorter time, lower cost.
Summary of the invention
The object of this invention is to provide a kind of drilling ship and drag lower water track sled, be convenient to stable and mobile, safety durable and be conducive to improve the efficiency of launching operation.
Object of the present invention will realize by following technical measures: comprise roller, hydraulic actuating cylinder, piston and coaster; Arse is installed roller, and coaster upper vertical is installed hydraulic actuating cylinder, and piston is installed on hydraulic actuating cylinder.
Especially, a pair roller is respectively installed before and after arse.
Especially, a roller is respectively installed before and after arse.
Especially, joint chair is installed on the top of coaster upper piston.
Especially, on coaster, draw gear is installed.
Especially, joint chair is frustum shape, height 400mm, diameter 1000mm; The high 600mm of rail chair; Coaster height 1095mm, the long 1552mm of coaster, the front and rear rolling wheel wheelbase 1012mm of coaster.
Advantage of the present invention and effect: with the sliding rail car of settling on track, share carrying drilling ship weight, implement to drag easily lower water operation, make the cost of large ocean engineering drill platform shaft, realize drilling platform safety of ship, the lower water of steady traction or first latent refuting, construction volume is few, engineering time is short and investment is low, and construction reliability is strong, commonality good; Corresponding auxiliary facility expense reduces, belong to water technology under the carrying that has alerting ability, there is saving of labor, save time, the remarkable advantage such as laborsaving, investment-saving, maneuverability, safe and reliable, overall economic efficiency, reduced the manufacturing cost of marine drilling platform, there is promotional value.
Accompanying drawing explanation
Fig. 1 be in the embodiment of the present invention 1 coaster along track alignment mounting structure schematic diagram.
Fig. 2 is side-looking direction structure schematic diagram when coaster is just installed in orbit in the embodiment of the present invention 1.
Reference numeral comprises: foundation pile 1, harbour 2, rail chair 3, roller 4, hydraulic actuating cylinder 5, piston 6, joint chair 7, coaster 8 tracks 9, draw gear 10.
The specific embodiment
The principle of the invention is, under existing many-sided technological means is supported, can accurate Calculation drilling ship drag lower water load carrying model and mode, for the rail vehicle bearing mode of implementing conveniently moving and be easy to manufacture provides foundation.
The present invention includes: roller 4, hydraulic actuating cylinder 5, piston 6 and coaster 8.
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment 1: as shown in Figure 1, roller 4 is installed in coaster 8 bottoms, and coaster 8 upper vertical are installed hydraulic actuating cylinder 5, and piston 6 is installed on hydraulic actuating cylinder 5.
In aforementioned, coaster is respectively installed a pair roller 4 before and after 8 bottoms.
In aforementioned, coaster is respectively installed a roller 4 before and after 8 bottoms.
In aforementioned, joint chair 7 is installed on the top of coaster 8 upper pistons 6.
In aforementioned, draw gear 10 is installed on coaster 8.
In aforementioned, foundation pile 1 has been built in harbour 2 bottoms, and harbour 2 tops are rail chair 3 fixedly, and track 9 is laid along rail chair 3, and coaster 8 is placed in track 9 tops with roller 4.
In aforementioned, joint chair 7 is frustum shape, height 400mm, diameter 1000mm; The high 600mm of rail chair 3; Coaster 8 height 1095mm, the long 1552mm of coaster 8, the front and rear rolling wheel 4 wheelbase 1012mm of coaster 8.
When the present invention works, according to place ability and drilling platform self structure feature, after carrying out intensity calculating check, three pairs of tracks 9 of interval 11200mm have been designed altogether, track 9 arranges that being divided on the bank harbour track 9 and half dives and refute 9 two parts that get on the right track: the cement concrete rail chair 3 of track 9 for building on harbour on the bank, and half dives refutes to get on the right track and 9 by H-girder and box steel structure, is combined; Along track 9 two the coaster 8 spacing 2800mm in directions front and back.
