Description
Technical field
The present invention relates to the removable short buoyancy tank connection structures of lower water workboat, belong to technical field.
Background technology
Lower water workboat is a kind of ship type between semi-submerged ship and barge, dedicated for ship and extra large work construction
Deng level land build after under the vertical, horizontal of lower water workboat water.In conjunction with shown in Fig. 1, lower water workboat is by main body buoyancy tank 1 and cloth
2 two parts of buoyancy high building composition on its quadrangle is set, be mainly used for being moved water under object implementation translates on the bank and is moved to from waterborne
Operation on the bank.
When by shifting object by being arranged in lower water workboat and after longitudinal and transverse track on the bank moves to this ship, in the effect of towboat
Under, this ship is dragged away from together with by shifting object at harbour to heavy hole (having the depth of water required enough by the drinking water of shifting object).Meeting
After operating condition, by main body buoyancy tank ballast tank water filling, this ship is sunk in water completely together with slowly sinking down into main body buoyancy tank by shifting object,
At this time only there are four corners high building on the water surface to provide ship enough buoyancy.After being in completely from floating state by shifting object,
Lower water workboat can be dragged away from, and then completed by water process under shifting object.
During above-mentioned lower water, only there are four corners high buildings on the water surface in main body buoyancy tank just sinks water completely
When, it just contacts the water surface due to being in by shifting object and does not generate any buoyancy also, the maximum load of hull bear is all by four at this time
The buoyancy that high building provides at angle undertakes, while being also the more difficult calculating operating mode for meeting code requirement of this ship Calculation of Stability.Based on this,
Arrange that a number of short buoyancy tank is the design effectively means for improving above-mentioned calculating operating mode stability on main body pontoon deck, it can be effective
Increase the operating mode splash line area, is conducive to improve vessel stability.
Currently, the connection type of the short buoyancy tank of ship type and main body pontoon deck mainly uses direct welding form, this knot
Configuration formula is easy for construction, weight is relatively light, but its have the shortcomings that it is more apparent.This ship is moved to by shifting object to meet, in master
A number of vertical, horizontal track is arranged on body pontoon deck.In addition, to meet the requirement of this ship positionning, in main body buoyancy tank first
A number of outfititem is also arranged on plate, fixed short buoyancy tank hardly results in reasonable Arrangement position.The arrangement of short buoyancy tank
So that main body pontoon deck arrangement is become too fat to move, while being also possible to generate interference with longitudinal and transverse track, influences to be moved water under object.
When carrying out other operations without short buoyancy tank miscellaneous function, the cutting repeatedly of short buoyancy tank, welding be user bring it is many not
Just, working efficiency is influenced, and is easily destroyed main body buoyancy tank local strength at this, increases unnecessary operation costs.
Short buoyancy tank is made into independent closed structure, short buoyancy tank four corners arrange small base and by bolt by short buoyancy tank and master
The structure type that body buoyancy tank is connected is relatively preferable, avoid user cut repeatedly, the workload of welding, improve work effect
Rate, but there are still other problems for this kind of structure type.First, the highly desirable bolt installation requirement that meets of four corners small base (leads to
The screw rod height of bolt need to be often more than, generally need 150~200mm), and the height of pedestal is necessarily by short buoyancy tank and main body buoyancy tank point
It leaves (at least height of small base).And the reason of adding short buoyancy tank it is above-mentioned be expressly recited, the two is separated to be bound to
It can not solve root problem.Secondly, after removing short floating box structure, the presence of each small base not only influences the cloth of main body buoyancy tank
It sets, while also can be that staff's work brings potential danger on ship.
Invention content
Technical problem to be solved by the present invention lies in providing a kind of removable short buoyancy tank connection structure of lower water workboat,
The dismounting of short buoyancy tank can be facilitated not destroy local strength of the main body buoyancy tank at this.
