Example 1
As shown in fig. 1, embodiment 1 of the present invention discloses a positioning and installing mold for positioning and installing bilge keels (not shown) on bilges of a ship body (not shown); the positioning and mounting die comprises an arc-shaped plate 1, a positioning part and two support plates 2, wherein the two support plates 2 are respectively connected with arc sections 11 at two ends of the arc-shaped plate 1, the positioning part is connected between the two support plates 2, and the positioning part is connected with the arc-shaped plate 1; the cambered surface section 12 of the cambered plate 1 is matched with the shape of the outer surface of the bilge part, the cambered plate 1 is attached to the bilge part, the plane where the positioning part is located penetrates through the curvature center of the outer surface of the bilge part, and the positioning part is aligned with the bilge keels.
In particular, since the area variation of the bilges is larger in the bow region or the stern region of the hull than in the middle region of the hull, the conventional single-piece template has a numerical deviation in the bow region and the stern region, for example, the bilge keels at two positions 300 mm apart in the hull direction in the bow region or the stern region, and a deviation of 9 mm in both the width direction and the height direction, although the installation and positioning angles of the bilge keels can be controlled well in the middle region. Thus, firstly, the construction steps and the construction difficulty are increased, secondly, even if repeated positioning is carried out for many times, the accuracy of the installation and positioning of the bilge keels is not high, and the effect is poor. The present invention thus effectively ameliorates this drawback by designing the cambered surface segments 12 with corresponding radians for the surface pattern of the cambered surfaces at different locations of the bilges in the bow area or stern area. The method not only can be used for positioning and mounting the bilge keels by taking a positioning and mounting die as a basis in the normal construction process of the ship body, but also can be used as a calibration template in the carrying stage of the ship body, can be used for checking problems of the bilge keels which are not folded due to deviation, and is a standard parameter for positioning and mounting the bilge keels.
The bilge keels are positioned and installed on the bilge parts of the bow area or the stern area of the ship body by adopting the positioning and installing die, and the bilge keels can be accurately positioned and installed, so that the plate bodies of the bilge keels can be approximately perpendicular to the tangent lines of the bilge parts, and the positioning and installing requirements are met.
In the positioning and mounting mold of the embodiment, an arc-shaped notch 3 is arranged at the joint of the positioning part and the cambered surface section 12 of the cambered plate 1, and the arc-shaped notch 3 is used for accommodating the seat plate of the bilge keels.
The arrangement of the arc-shaped notch 3 can avoid the seat plate of the bilge keels, and the positioning and mounting effects of the bilge keels are not affected.
In the positioning and mounting mold of the present embodiment, the positioning portion is the flat plate 4 connected between the two support plates 2.
The arrangement of the flat plate 4 improves the strength between the two support plates 2, and increases the supporting and aligning effects of the positioning part on the bilge keels when the bilge keels are positioned and installed.
In the positioning and mounting mold of the present embodiment, a holding portion is provided between the two support plates 2, and the holding portion is located in a space surrounded by the arc plate 1 and the two support plates 2.
The holding part is convenient for a worker to stably operate the positioning and mounting die when positioning and mounting the bilge keels, and the positioning and mounting accuracy and effect of the bilge keels are improved.

The holding part is arranged to be the straight rod 7, so that the holding of staff can be easier.
In the positioning and mounting mold of the present embodiment, the shape of the cambered surface section 12 of the cambered plate 1 is changed according to the surface shape change of the outer surface of the bilge part along the head-to-tail direction of the ship body.
The positioning and mounting dies of the arc-shaped plate 1 with the arc-shaped surface sections 12 with different surface shapes are correspondingly designed at different positions of the bilges of the bow area or the stern area of the ship body, so that the positioning and mounting effect of bilge keels at all positions of the bilges of the bow area and the stern area can be ensured.
In the positioning and mounting mold of the present embodiment, the radius of curvature of the cambered surface section 12 of the cambered plate 1 gradually decreases from the middle region of the hull toward the bow region or stern region of the hull.
By adopting the design of the positioning and mounting die, the bilge keels of the bilges in the bow area and the stern area and the bilge keels of the bilges in the middle area are ensured to have approximately the same anti-rolling performance.
In the positioning and mounting mold of the present embodiment, the positioning and mounting mold is made of wood.
The positioning and mounting die is designed into a wooden structure, and the weight of the positioning and mounting die is about 1 kg, so that the cost of the positioning and mounting die is lower, the force consumed by a worker in operation is also smaller, and the operation burden of the worker is reduced.
Example 2
As shown in fig. 2, embodiment 2 of the present invention discloses a positioning and mounting die.
In the present embodiment, the positioning and mounting mold has the same partial structure as that of embodiment 1, except that the positioning portion is designed as a hollowed-out structure.
In the positioning and mounting mold of this embodiment, the positioning portion includes a connecting rod 5 and two straight-line segments 6, the straight-line segments 6 are in one-to-one correspondence with the support plate 2 and the straight-line segments 6 are disposed on the support plate 2, the connecting rod 5 is disposed at one end of the positioning portion far away from the arc plate 1, and the connecting rod 5 is connected between the two straight-line segments 6.
