Abstract
The utility model relates to a novel ship positioning and shifting system: two trolley positioning pile systems and one fixing positioning pile system on a ship, and three positioning piles are driven by a hydraulic device to ascend and descend; and the trolley systems are horizontally arranged on a main deck, trolleys can be driven by a hydraulic system and move horizontally together with the positioning piles. When the ship needs to be precisely positioned and constructed, the three or two piles are simultaneously inserted into the sea or the river, a mechanical positioning device and the hydraulic system lock the trolleys at required positions so as to ensure the ship is stably positioned on the sea surface and provide a reliable operation platform for construction equipment. When the ship is horizontally shifted, ship shifting oil cylinders first respectively shift the two trolleys and the positioning piles to required positions; after the positioning piles are inserted into the sea or the river, the two ship shifting oil cylinders are synchronously started, so that the trolley positioning piles and the ship have relative movement so as to realize the horizontal and parallel shifting of the ship.
Description
Technical field
The utility model designs a kind of later-model ship's fix and moves boat system, and present technique can be used for inland river and coastal nonpower driven vessel, does not rely on the accurate location of anchoring equipment realization boats and ships and laterally moves ship.
Background technology
At present, more non-motor-driven auxiliary vessel adopts anchoring system to position and moves ship, because the defective of system itself, under the bigger condition of operating water depth and stormy waves, boats and ships drift with the tide, sometimes even " dragging of anchor " phenomenon takes place, boats and ships are difficult to realize location exactly, therefore, can only be chosen in stormy waves and carry out operation less period, shipping work efficient reduces greatly, and construction quality also can not get guaranteeing.On the other hand, carry out boats and ships when displacement by anchoring system, mobile distance is difficult to accurate control, simultaneously, must rely on anchor boat when spread is cast anchor in the construction area operation and " guards the emperor " for it entering, thereby increase construction cost.
In order to improve the accuracy of positioning of boats and ships, stability when improving operation, part marine engineering ship has adopted the form of jack-up platform, four work piles are set, boats and ships rely on the ability of self can lift away from the water surface, boats and ships base fixed, operation are not influenced by stormy waves, can be than carrying out operation under the harsh conditions.But, adopt jack-up platform, to move ship at every turn and need fall ship and rise ship again, consume a lot of non-cutting time, and operating efficiency reduces.Moving ship time also need be auxiliary by means of the anchoring system or the power driven vessel of routine.
Summary of the invention
For overcome existing anchoring location and move location that boat system exists, to move ship inaccurate, and the too low deficiency of jack-up platform work efficiency, the utility model provides a kind of three to locate and move ship's case, can not only realize the accurate location of boats and ships, and can carry out the boats and ships lateral offset easily by self, and the distance that moves is accurate, controlled.
The technical scheme that its technical matters that solves the utility model adopts is: two cover chassis work pile systems and a cover stationary positioned stake system aboard ship are set, and three work piles drive by hydraulic efficiency gear to be realized rising and descending; On table system horizontally set and the main deck, chassis can be driven by hydraulic efficiency pressure system, with the work pile side travel.When boats and ships need accurately location construction, (river) end, sea, inserted in three (or two) stake simultaneously, chassis is locked in the position that requires by mechanical positioner and hydraulic efficiency pressure system, can guarantee that this ship is steadily due to the sea, for preparation of construction provides a failure-free job platform.When needs carry out lateral offset to boats and ships, move the position that the ship oil cylinder moves to two chassis and work pile requirement at first respectively, work pile is inserted sea (river) at the end, start two more synchronously and move the ship oil cylinder, make between chassis work pile and boats and ships and produce relative motion, thus the horizontal parallel shifted of realization boats and ships.
The beneficial effects of the utility model are: the accurate location that relies on present technique can realize boats and ships, and the lateral offset of boats and ships, mobile distance is accurate, controlled.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a kind of novel ship location and moves the boat system birds-eye view
Fig. 2 is a kind of novel ship location and moves the boat system lateral plan
Among the figure: 1. the chassis work pile, 2. chassis, 3. the work pile jacking system, 4. the chassis guide rail, 5. move ship oil cylinder, 6. cylinder support, 7. stationary positioned stake
The specific embodiment
In Fig. 1, at boats and ships bow, stern one cover chassis work pile system is set respectively, at midships section one cover stationary positioned stake system is set, chassis work pile system by chassis work pile (1), chassis (2), work pile jacking system (3), chassis guide rail (4), move ship oil cylinder (5), cylinder support (6) is formed, stationary positioned stake system is made up of stationary positioned stake (7), work pile jacking system (3).
When needs position boats and ships, (river) end, sea, inserted in three (or two) stake simultaneously, by mechanical positioner and hydraulic efficiency pressure system chassis is locked, all do not have relative motion between chassis work pile (1), chassis (2) and the chassis guide rail (4), can guarantee the mooring stability location that links with chassis guide rail (4).The size of work pile (diameter, wall thickness) should be according to the accuracy of positioning of the wind of shipping work, unrestrained condition, job requirements and the material of work pile, the employing finite element method is chosen, therefore, adopt present technique, the accuracy of positioning of boats and ships can satisfy the requirement of construction operation.
When three piles insert sea (river) during the end simultaneously, adopt following steps, can realize displacement to boats and ships:
1, passes through the work pile jacking system (3) of a chassis work pile system, chassis work pile (1) is pulled up (at this moment, other two work piles still insert the end, sea (river), can guarantee that boats and ships are not shifted), start and move the distance that ship oil cylinder (5) makes chassis (2) movement requirement, again work pile is inserted at (river) end, sea, utilize mechanical positioner and hydraulic efficiency pressure system chassis to be locked in this position.
2, adopt above-mentioned identical step, make the work pile mobile phase distance together of another chassis work pile system, again work pile is inserted at (river) end, sea, and chassis is locked.
3, stationary positioned stake (7) is pulled up, what start synchronously two chassis work pile systems moves ship oil cylinder (5), because chassis work pile this moment (1) is fixed in the end, sea (river), chassis (2) is fixing thereupon, cylinder support (6) will drive the horizontal parallel shifted of hull, and the stroke of oil cylinder is the miles of relative movement of boats and ships.
4, when boats and ships need be shifted next time, repeat said process.
Claims (1)
1. boat system is located and moved to a novel ship, form by two cover chassis work pile systems and a cover stationary positioned stake system, chassis work pile system comprises chassis work pile, chassis, work pile jacking system, chassis guide rail, moves ship oil cylinder, cylinder support, stationary positioned stake system comprises stationary positioned stake, work pile jacking system, it is characterized in that: the table system lateral arrangement is on main deck.
