Description

A kind of buoyancy tank connection structure

Technical field

The utility model relates to buoyancy tank waterborne is interconnected with one another the connection structure that becomes one.

Background technology

Operation at sea engineerings such as the training of channel, port and pier construction, bridge erection and the water surface are floating clearly need be built the operation at sea platform.The area of these operation at sea platforms and volume are very big usually, and it is difficult to whole transhipment, when the change operating location frequently changes, are difficult to use repeatedly.Can when frequently changing, recycle operating location in order to make the operation at sea platform, can adopt buoyancy tank waterborne to be assembled into job platform, when it changes at operating location, job platform can be taken into apart buoyancy tank waterborne transports, and after being transported to next operating location, can again the buoyancy tank connection be assembled into job platform again.

At present, the connection mode between buoyancy tank waterborne mainly contains the connection mode of attachment strap welding and bundlees connection mode.No matter any connection mode all exists many defectives and certain operation hidden danger.

For the binding connection mode, be bundled into one by rope between its buoyancy tank and buoyancy tank, can't rigidity fix between its buoyancy tank, in stormy waves, very easily cause the association's unstability after the binding.And the deck plane of adjacent buoyancy tank is difficult to guarantee on same plane, and its construction machinery and equipment is arranged can not form integral body with being connected, and floor space can't effectively utilize, operation inconvenience, and have certain job safety hidden danger.

Connect welding manner for attachment strap, need carry out operations such as casing contraposition, welding waterborne during connection; When the shipment dismounting, need to carry out cutting operation again, big, the non-engineer operation time of its work capacity is long, efficient is low, deficiency in economic performance.

The utility model content

It is firm that the utility model is intended to provide a kind of connection, removes and installs simple, conveniently, quick, can more effectively utilize the buoyancy tank connection structure of floor space.

Buoyancy tank connection structure described in the utility model comprises many cloudy buckle and the positive buckles to cooperatively interacting on the joint face that is separately positioned on adjacent buoyancy tank; Described cloudy buckle is embedded in the joint face place of one buoyancy tank, the outside plate of its shell and buoyancy tank and structural shapes one or integrally welded, make cloudy buckle become the part of buoyancy tank, form watertight structure with the internal cavity of buoyancy tank, the inside of cloudy buckle also arranges a plurality of draw-in grooves side by side, and draw-in groove is towards the joint face of another buoyancy tank; Described positive buckle is embedded on the corresponding joint face of adjacent buoyancy tank, outside plate and the structural shapes one or integrally welded of the same and buoyancy tank of its shell, become the part of buoyancy tank, form watertight structure with the internal cavity of buoyancy tank, a plurality of inserted blocks side by side are set in the inside of positive buckle, each inserted block is corresponding with each draw-in groove of cloudy buckle respectively, and inserted block inserts respectively in the corresponding draw-in groove and matches with draw-in groove; The joint of each yin, yang buckle also is provided with locating dowel pin, and locating dowel pin runs through each draw-in groove and inserted block to matching of yin, yang buckle simultaneously, and the yin, yang buckle is locked mutually.

When building the operation at sea platform, the joint face of adjacent buoyancy tank to be connected is closed up mutually, the inserted block of sun buckle embeds in the draw-in groove of cloudy buckle, locating dowel pin is inserted at the joint top of the draw-in groove that matches and inserted block at each, and the negative and positive buckle is locked mutually, thereby realize simple, connection fast between adjacent buoyancy tank, when need are dismantled, extract locating dowel pin, the inserted block of positive buckle is isolated the draw-in groove of cloudy buckle, can realize separating each buoyancy tank connected to one another, thereby realize transhipment.The locking of negative and positive buckle can form and be rigidly connected secure and reliable connection ,Buoyancy tank connects the aft deck face makes each buoyancy tank form an integral body on same plane, the deck working area can be utilized effectively, and reduces operation at sea labour intensity greatly, and safety more can be protected.

The specific embodiment

As shown in Figure 1 to Figure 3, a kind of buoyancy tank connection structure comprises being separately positioned on cloudy buckle 11 and the positive buckle 21 that three couple on adjacent buoyancy tank 1,2 the joint face 12 cooperatively interacts; Cloudy buckle 11 is embedded in joint face 12 places of buoyancy tank 1, outside plate 14 and the structural shapes one or integrally welded of cloudy buckle 11 shells and buoyancy tank 1, make cloudy buckle 11 become the part of buoyancy tank 1, form watertight structure with the internal cavity of buoyancy tank 1, the inside of cloudy buckle 11 also arranges three draw-in grooves 13 side by side, and draw-in groove 13 is towards the joint face 22 of buoyancy tank 2; Sun buckle 21 is embedded on the corresponding joint face 12 of adjacent buoyancy tank 1, outside plate 24 and the structural shapes one or integrally welded of the same and buoyancy tank 2 of sun buckle 21 shells, become the part of buoyancy tank 2, form watertight structure with the internal cavity of buoyancy tank 2, three inserted blocks 23 side by side are set in the inside of positive buckle 21, each inserted block 23 is corresponding with each draw-in groove 13 of cloudy buckle 11 respectively, and inserted block 23 inserts respectively in the corresponding draw-in groove 13 and matches with draw-in groove 13; The joint of each cloudy buckle 11, positive buckle 21 also is provided with locating dowel pin 3, and locating dowel pin 3 runs through draw-in groove 13 and the inserted block 23 that 3 couple of cloudy buckle 11, positive buckle 21 matches simultaneously, and cloudy buckle 11, positive buckle 21 are locked mutually; By marine towage, land automobile, train or boats and ships transportation, adjacent buoyancy tank is transported to the operation waters when building the operation at sea platform, buoyancy tank joint face to be connected is closed up mutually, the inserted block 23 of sun buckle 21 and the draw-in groove 13 of cloudy buckle 11 are aimed at substantially, inserting locating dowel pin 3 links together buoyancy tank 1,2 fast, also can adopt said method in advance buoyancy tank 1,2 to be connected and fixed on the coast, send into the operation waters by air bag or slide rail and carry out engineer operation.
