Abstract

A kind of mounting process of the rectangular mud door of dredger, including 10 steps, the mounting process of the rectangular mud door of this dredger is in the assembling process of rectangular mud door, adjustment otic placode and the horizontal positions Ni Men after mud crossette plate is connect by axis pin with mud door body, it reaches horizontal consistent, then mud doorway is pushed it into, pass through jack leveling, spot welding otic placode again, the operation directly has adjusted the horizontal position of otic placode and mud door body, axis hole is set to reach same position, secondary operation need not be carried out to axis hole again after installing, reduce operation sequence, mitigate worker workload, make working efficiency higher.

Description

The mounting process of the rectangular mud door of dredger
Technical field
The present invention relates to steel constructions to assemble field, the more particularly to mounting process of a kind of rectangular mud door of dredger.
Background technology
Rectangular mud door on hull rectangular Ni Men and is fanned rectangular mud door by the rectangular mud door of midship two and formed by coming alongside, two fans Rectangular mud door is had any different in addition to boss and adhesive tape clamping plate, other structures all same.Rectangular mud door main components are by above and below Plate, otic placode, the clamping plate composition for adjusting web, internal gusset and fixing seal adhesive tape.In rectangular mud door installation process, weight is needed Point considers the levelness of the concentricity of hinge joint otic placode and panel and adjusting web in rectangular door, to ensure rectangular mud The installation accuracy of door, 104625452 A of prior art CN disclose a kind of mounting process of the rectangular mud door of dredger, the patent Using elder generation, in mud door installation otic placode, simultaneously spot welding is fixed, and in the horizontal position by adjusting two fan mud doors, the positioning of mud door is assemblied in Mud doorway, but during the installation process, due to there are welding deformation, needing to reserve 20mm processing in otic placode fixing assembling front-axle hole Surplus will also carry out the finishing of otic placode upper shaft hole after the completion of then being welded between each assembly parts on rectangular mud door again, and process is more, It is troublesome in poeration, increase worker labour.
Invention content
To solve the above problems, the present invention one kind is provided can the rectangular mud door installation accuracy of effective guarantee, convenient dredger The mounting process of rectangular mud door.
The technical solution adopted by the present invention to solve the technical problems:
A kind of mounting process of the rectangular mud door of dredger, includes the following steps:
1), mud door body is disposed horizontally on interim moulding bed, otic placode is connect with mud door body by axis pin, makes ear using tooling Plate is horizontal with mud door body;
2) two fan mud door body of left and right, is arranged into the distance completely measured between two fan mud door body, and is recorded;
3) two fan mud door body of left and right, is pushed into mud doorway lower part respectively, from lower to upper, mud door body is headed into mud doorway;
4), by mud door body leveling;
5) and then the distance between mud door body is fanned in measurement two, and is recorded, with step 2)In data compared and adjust it is consistent, Inspection otic placode is bonded situation with mud doorway stringer board, optionally mowing otic placode surplus;
6), spot welding otic placode;
7), mud crossette plate axis pin is removed, by tooling platform, mud door body is made to remove;
8) dummy shaft tooling, is done, several lug plate holes centers are passed through, otic placode is then welded, dummy shaft tooling is dismantled after cooling;
9), two fan mud door body are headed into mud doorway again, mud crossette plate axis pin is properly installed;
10), again through jack by mud door body leveling, Ni Men is fixed lower part with adjusting apparatus, completes the installation of rectangular mud door.
Beneficial effects of the present invention:The mounting process of the rectangular mud door of this dredger is in the assembling process of rectangular mud door, pin Adjustment otic placode and the horizontal positions Ni Men after mud crossette plate is connect by axis with mud door body, reach level unanimously, are then pushed away Enter mud doorway, by jack leveling, then spot welding otic placode, which directly has adjusted the horizontal position of otic placode and mud door body, make Axis hole reaches same position, need not carry out secondary operation to axis hole again after installing, reduce operation sequence, mitigate work Person works measure, and make working efficiency higher.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Mud door body 1, otic placode 2, stringer board 3, lug plate holes 4, bolt 5.
Specific implementation mode
It is described further as embodiment using the rectangular mud door of 7000m3 trailing suction hopper dredgers.
An embodiment of the present invention provides a kind of mounting process of the rectangular mud door of dredger, and the technical solution is as follows:
Mud door door body is disposed horizontally on interim moulding bed by the first step, is connect mud crossette plate 2 with mud door body 1 by axis pin, Keep otic placode 2 horizontal with mud door body 1 using tooling, mud door bolt axis and 4 tolerance of mud crossette plate hole should meet IHC requirements(Fill mud door body Before, ensure that the segment level within the scope of mud door body, Outer Bottom Plating flatness are not more than 4mm, it should be with floor after mud door body is properly installed Height fall is not more than 2mm).
Two fan mud door body 1 of left and right is arranged complete, the distance between two fan mud door body 1 of measurement by second step, and is recorded.
Mud door body 1 is pushed into mud doorway lower part by third step respectively, from lower to upper, mud door body 1 is headed into mud doorway.
4th step often fans 1 four jiaos of mud door body respectively 1 jack of setting, by jack by 1 leveling of mud door body.5th step Then the distance between two fan mud door body 1 is measured, and is recorded, with step 2)In data compared and adjust consistent, check ear Plate 2 is bonded situation with mud doorway stringer board 3, optionally 2 surplus of mowing otic placode.
6th beans-and bullets shooter welds 4 otic placodes 2, every fusion length 50mm, welding seam distance 50mm.
7th step removes 2 axis pin of mud crossette plate, by tooling platform, mud door body 1 is made to remove.
8th step does dummy shaft tooling, passes through 24 centers of lug plate holes, then welds otic placode 2, and both sides are applied simultaneously when welding Weldering, welding current is small as far as possible, and 2 deformation of otic placode is observed in welding, during freezing the rotation dummy shaft of discontinuity with Anti- dummy shaft clamping stagnation is killed, and dummy shaft tooling is dismantled after cooling.
9th step again heads into two fan mud door body 1 in mud doorway, and mud crossette 2 axis pins of plate are properly installed, during filling axis pin, It slowly taps, it is appropriate to experience lower drag uniform.It is after properly installed, the Anti-loosing-cover spot welding at axis pin both ends is secured.
Tenth step is again through jack by 1 leveling of mud door body, and the lower parts Ni Men bolt 5 is fixed, and entrance is next Procedure.
The dummy shaft tooling diameter is more than pin diameter.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
