Description
Technical field
The present invention relates to ship assembly technical fields, and in particular to a kind of flat-bulb steel docking facilities.
Background technique
In total group, carrying operation process, the structure for carrying out segment folding assembly needs to dock and weld two-by-two ship,
Wherein flat-bulb steel occupies 90 or so percent, therefore the installation and docking of flat-bulb steel are important works during ship assembly
Sequence.Iron caulked is entered 7 words generally using 7 character codes are fixed in flat-bulb steel neighbouring position spot welding by flat-bulb steel docking in the prior art
With among flat-bulb steel, hand hammer hammering is adjusted code, and then flat-bulb steel is docked in spot welding, and rearmost point welding angle connects the fixed spot welding of outside plate,
After being welded and fixed, remove 7 character codes, and need batch mend mill etc. operations spot welding position is repaired, take a substantial amount of time and
Energy, in actual installation process, segment folding mouth generally has 50 flat-bulb steel abutment joints to need to handle, larger workload；Even
In a few thing environment, in double bottom, liquid tank, spot welding polishing is relatively difficult, general welded pipeline arrangement, pipeline cloth of polishing
It sets and requires to expend more than half an hour.
Summary of the invention
In view of the above technical problems, the present invention provides a kind of flat-bulb steel docking facilities, are capable of providing flat-bulb steel assembly
Efficiency, it is simple for structure without 7 character codes, it is convenient for safeguarding to maintain and operate with, and gross weight is lighter, answers convenient for building berth carrying
With.
To achieve the above object, the present invention provides a kind of flat-bulb steel docking facilities, including for being detachably secured to ship
Fixed structure on oceangoing ship, the fixed structure are equipped with top-pressure mechanism, and the top-pressure mechanism includes press seat, the press seat
It is fixedly connected by connector with fixed structure, mandril is vertically disposed on the press seat, is additionally provided on the press seat
The mandril is driven to move up and down to press the transmission mechanism of flat-bulb steel.
Compare the prior art, beneficial effects of the present invention:
1, it compares and is fixed and the mode of the embedding hammering of iron using 7 character code spot welding in the prior art, need to adopt in the prior art
It with a large amount of 7 character codes and needs a large amount of batches to mend mill operations, substantially needs using to 7 character codes at least 200 times, then spot welding point needs at 200
The mounting plate of ship installation place can be damaged at least 40 when criticizing and remove or cut off and polish, and remove or so, this
Sample needs repair welding to polish, time-consuming work consuming, and the present invention is capable of providing the efficiency of flat-bulb steel assembly compared with prior art, without
7 character codes are fixed on ship using fixed structure absorption, drive the mandril on press seat to move down top using transmission mechanism
Then pressure ball band steel is hammered using hawkbill, reduce in this way using the fixed process made of 7 character codes and remove process, improve
The efficiency of flat-bulb steel installation.
2, the flat-bulb steel docking of the prior art, which uses, 7 words of processes and dismounting such as is largely welded and is welded and fixed
The process of code, multiple welding are easy to damage ship mounting plate, for example, 50, segment folding mouth or so flat-bulb steel abutment joints cause to
The fixed something that gives the game away of spot welding at few 200；And multiple hammering ship mounting plate is needed, is repeatedly hammered using hawkbill and is also easy to damage
The bulb of flat-bulb steel, or even need to carry out repair welding to bulb, repair welding workload in the prior art is at 100 or so, this Shen
Ball steel docking facilities please directly use mandril to press flat-bulb steel, do not need the dismounting of multiple welding and 7 character codes, ball is flat
