Technical Field
The invention relates to the field of ship construction, in particular to a method for strengthening toe ends of a ship toggle plate.
Background
In the design process of the ship, the strength of the ship body and the dead weight of the empty hull of the ship body need to be selected in a measuring mode, and the maximum cargo-carrying tonnage meeting the strength requirement needs to be achieved. Therefore, the ship structure is largely designed by the toggle plate, and the dead weight of the ship shell is not excessively increased while the strength is improved.
In the process of manufacturing the ship body section, the toggle plates are often installed in a small assembling stage, one end of each toggle plate is welded to a ribbed plate, the other side of each toggle plate is in a free state, and the toggle plates need to be transported to a field for assembling and constructing in a large assembling mode. In the process of transferring the small assembled structure, the toe end of the toggle plate is often deformed after being collided, and additional reworking correction is needed after the subsequent process.
Prior art utility model patent as application number 201820431362.X discloses a protection frock for hull bracket toe end, protects the bracket toe end through making protection frock.
However, due to the difference of specifications of the toggle plates on the ship body, when the toggle plates are collided by external force, the deformation positions of the toggle plates are different due to different sizes of the toggle plates, and the requirement for protecting the toe ends of the toggle plates with different specifications is difficult to meet through manufacturing a protection tool.
Disclosure of Invention
In order to solve the technical problems, the invention provides a method for strengthening the toe end of a ship toggle plate, which effectively solves the problem of deformation of the toe end of the toggle plate in the process of moving small groups vertically and can protect the toe ends of the toggle plates with different specifications.
The technical purpose of the invention is realized by the following technical scheme:
a method of strengthening the toe ends of a ship's elbow to prevent toe end deformation during transportation of a small assemblage of upper elbows, the method comprising the steps of:
and 3, after the group is moved and transported vertically, detaching the reinforcing plate.
Further, in step 1, the selected toggle plate is located at a corner of the small stack or the toggle plate is the highest toggle plate on the floor on which it is located.
Furthermore, in the step 2, one side of the toggle plate, which is close to the bottom plate, is provided with an R hole, one end of the reinforcing plate is 10-20mm away from the R hole,
further, the other end of the reinforcing plate is 3-5mm beyond the toe end of the toggle plate.
Further, the width of the reinforcing plate is greater than the thickness of the toggle plate.
Further, the width of the reinforcing plate is 4 to 5 times the thickness of the toggle plate.
Further, in step 2, the toggle plate and the reinforcing plate are spot-welded to each other on one side of the toggle plate.
Further, the spot welding positions are located at one-third and two-thirds of the length of the contact position of the reinforcing plate and the toggle plate.
Further, the length of the spot welding is 5-10 mm.
Further, the toggle plate welding position is located on the center side of the width of the reinforcing plate.
Compared with the prior art, the invention has the beneficial effects that the deformation problem of the toe end of the toggle plate in the transfer process is solved by directionally protecting the toe end of the toggle plate with special area and special size on the component; the small erection area is directly provided with the reinforcing strips through spot welding, so that the operation continuity of the small erection area is improved. In the middle and large assembling area, the reinforcing lath is well protected by mechanically removing the toe end of the toggle plate.

Detailed Description
The technical solution of the present invention is further described below with reference to specific embodiments:
a method of strengthening the toe ends of a ship's elbow to prevent toe end deformation during transportation of a small assemblage of upper elbows, the method comprising the steps of:
when the reinforcing plate 1 is selected, an R hole 5 is formed in one side, close to the bottom plate 4, of the toggle plate 3, the distance from one end of the reinforcing plate 1 to the R hole 5 is 10-20mm, and the other end of the reinforcing plate 1 exceeds the toe end of the toggle plate by 3-5 mm; the width of the reinforcing plate is greater than the thickness of the toggle plate, and preferably the width of the reinforcing plate is 4-5 times the thickness of the toggle plate.
When the reinforcing plate is spot-welded, the bracket and the reinforcing plate are spot-welded and fixed on one side of the bracket, so that the reinforcing plate is convenient to remove subsequently, the spot welding position 2 is positioned at one third and two thirds of the contact position of the reinforcing plate and the bracket, and the spot welding length is 5-10 mm; the weld location of the toggle plate is located on the center side of the width of the gusset plate, preferably one third of the width of the gusset plate, as shown in FIG. 2, to facilitate subsequent mechanical removal of the gusset plate.
And 3, after the group is moved and transported vertically, removing the reinforcing plates, and storing the reinforcing plates in a centralized manner after the reinforcing plates are removed, so that the reinforcing plates can be repeatedly used.
