Description
Technical field
The invention belongs to warship equipment technical fields, more specifically, be related to it is a kind of for warship
Tire plate pressing device.
Background technique
Current shipbuilding mostly uses greatly block system, in short, hull is divided into several segmentations, first in workshop or
On the moulding bed or platform in other places build segmentation, then by constructed all segmentations on building berth general assembly at hull.Segmentation
Type have flat section (such as platform, flush deck, bulkhead, the segmentation of straight topside), curved section (such as deck, topside, single bottom
Segmentation etc.), three dimensional unit (such as double bottom, wing tank are segmented with platform/bulkhead annular segments and superstructure).Respectively
The working procedure of segmentation is general are as follows: tire → scribing line → internal structure on Deck Plating (or platform board/inner bottom plating/outside plate), bulkhead, outer
Plate, bracket, benefit plate → propping → welding, polishing, correction → are applied for checking and examination.Above-mentioned upper tire plate has platform board, Deck Plating, bulkhead plate, outer
Plate, inner bottom plating etc., slide plate can be all deformed after workshop is spliced because of welding, although can be rolled out by large-scale roll bending machine,
But the turn, transhipment after jigsaw can be also deformed.Although and being examined after curved slab processing with template, actually still presence
Line style deviation, the deformation of these slide plates and curved slab deviation about 0-15mm, there is also the deviation of about 20mm, therefore upper tire sometimes
Plate and moulding bed all can assist compressing with 1-2 tons of briquettings, and upper tire plate is fixed with moulding bed pillar with spot welding.The prior art
In, the technical solution compressed to upper tire plate is as shown in Fig. 6.Such scheme, the work that needs to drive a vehicle in work progress play a heavy industry and match
It closes, when upper tire plate has inclination, briquetting is likely to occur sliding and causes safety accident.Segmentation quadrangle can be had after the completion by being segmented welding equipment
The welding deformation upwarped, and the measure of shipyard still increases briquetting counteracting internal stress before segmented welding, while in segmentation quadrangle
And reduce subsection deformation, the same security risk there is also figure one, in addition needed for stacking, handling, the cooperation of briquetting be also time-consuming
Laborious process.
Summary of the invention
The technical problems to be solved by the present invention are: in view of the deficiencies of the prior art, it is simple to provide a kind of structure, Neng Goufang
So that upper tire plate reaches theoretical position, while it can reduce segmentation welding equipment by realizing that upper tire plate is close to moulding bed pillar purpose
Deformation, it is ensured that it is safe operation, convenient, it effectively avoids compressing using the upper tire plate for warship of the safety accident of briquetting and fills
It sets.
Solve the problems, such as techniques discussed above, the technical scheme adopted by the invention is as follows:
The present invention is a kind of upper tire plate pressing device for warship, and upper tire plate is supported on moulding bed pillar, described
The upper tire plate pressing device for warship include device noumenon, the device noumenon is set as anti-C character form structure, dress

Answering property is good, and the moulding bed pillar in workshop is all full paving arrangement, but the length and width dimensions being respectively segmented are different.The present invention compresses " G " type
Device (compactor) is designed as separable two parts, and the hardened structure of the fixed ear that compactor is connect with moulding bed pillar is simple, can be
Moulding bed specific region is arranged more, avoids repeating to dismount, connecting plate can remove at any time, be installed on any tire for having fixed otic placode
On post setting, while the weight that alleviator is moved.Five, convenient for storage, the lower members of this covering device by " Z " type fixation
Otic placode and two groups of bolt fastener compositions, are generally mounted on moulding bed pillar.The upper part of pressing device is whole " J " type
Component, storage are lost in handling process without dismountable components.The annulus of screw rod upper end is also convenient for scene and hangs on row's hook,
It is visually managed for 5S.Six, improve efficiency, reduce labor intensity, compactor of the invention by one man operation, without work of driving a vehicle,
Heavy industry cooperation is played, work post cooperation, waiting time etc. have been subtracted, also without electrical welding operation.Seven, cost is reduced, compactor is repeatable to be made
With reducing the cost of labor cooperated with up tire plate work post, also as without the work that spot welding, sealing-off and overlap are rejected, directly
Connect save labor hour, kinetic energy, auxiliary material expense.Eight, presentation quality is improved, compactor is pressed in tire by Universal pressing head
On plate, without the marking after construction, is more repaired without electric welding and the trace of polishing, presentation quality are greatly improved.
Upper tire plate pressing device of the present invention for warship, the upper tire plate pressing device for warship
Entirety is adaptation level and inclined upper tire plate and fast assembling-disassembling requirement, device noumenon lower end can lead in " G " font structure
Multiple bolts are crossed to be fastenedly connected with moulding bed pillar, in this way, realize the connection and positioning of upper tire plate pressing device itself, and device sheet
The screw rod installed in the thread bush of 3 upper end of body can be applicable in the plate thickness of different upper tire plates with lift adjustment.It needs to upper tire plate pressure
When tightening position, after the length-width direction Primary Location of upper tire plate, so that it may rotary screw applies clockwise torque in screw rod,
Screw rod decline compresses upper tire plate, achievees the purpose that tire plate is close to moulding bed pillar.And when needing to release compression, apply and turns round counterclockwise
Square is moved away from tire plate on screw rod, on screw rod, realizes the releasing compressed to upper tire plate.Pressing device of the invention, for ship
Oceangoing ship is manufactured and is proposed, while being primarily adapted for use in the fixation of the biggish upper tire plate of weight, as long as rather than the device that is capable of fixing all
It can directly use, be key innovations of the invention for the compression of the upper tire plate of specific ship therefore.Institute of the present invention
