Description

Technical Field

[0001] This utility model relates to the field of lifeboats, specifically to a lifeboat gantry. Background Technology

[0002] The bolt holes on the back plate of the currently used lifeboat davit have some slack between them and the bolts used for fixing. This can cause the lifeboat davit to still tend to move after installation. This can lead to uneven stress on some bolts, resulting in a short service life for the lifeboat davit and also creating a risk of water leakage.

[0003] Furthermore, the eye plates on the currently used lifeboat davits require additional reinforcing plates on both sides to increase their strength. However, these reinforcing plates need to be welded to the eye plates, which involves a large amount of welding and reduces the installation efficiency of the lifeboat davits. Utility Model Content

[0004] The purpose of this invention is to provide a lifeboat jack that solves the problems of water leakage and low installation efficiency of current lifeboat jacks.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A lifeboat jack includes a bow jack and a backplate. The bow jack is welded to the backplate, which has a plurality of hinge holes. Each hinge hole has a hinge hole bolt, and the bottom of the hinge hole bolt has a nut that is compatible with it.

[0007] Furthermore, the bow mount includes an eye plate and a base plate, the eye plate and the base plate being integrally formed; the eye plate is located on top of the base plate, and the bottom of the base plate is welded to the back plate; the eye plate is provided with through holes.

[0008] Furthermore, the eye plate is annular, and the top surface of the base plate is an arc shape that fits the eye plate; the bottom surface of the base plate is flat, and both sides of the base plate are inclined sides that extend from the top surface to the bottom surface, and the two inclined sides are not symmetrical.

[0009] Furthermore, the back plate has a rectangular cross-section, and the hinge holes are symmetrically distributed on both sides of the back plate, with the hinge holes on both sides evenly distributed along the long side of the back plate.

[0010] Furthermore, the two end faces of the eye plate have a first symmetry plane, and the bottom plate has a second symmetry plane. Both the first and second symmetry planes are in the same direction as the distribution of the reamed holes; and the first and second symmetry planes coincide.

[0011] Furthermore, there are a total of 8 hinge holes, with 4 hinge holes on each side of the back plate.

[0012] Furthermore, both oblique sides are tangent to the eyeplate, and the width of the base plate is smaller than the width of the eyeplate.

[0013] By adopting the above technical solution, the beneficial technical effects of this utility model are:

[0014] This invention features multiple reamed holes on the backplate, through which reamed bolts are passed. The unthreaded portion of the bolts fits snugly against the holes, eliminating gaps and preventing the lifeboat pylon from shifting. This also eliminates the risk of leakage. Furthermore, by integrally molding the bow pylon, this invention eliminates the need for welding, reducing workload and increasing the pylon's strength. Attached Figure Description

[0016] Figure 2 This is a top view of a lifeboat gantry.

[0017] Figure 3 This is a schematic diagram showing the fit between a reamed hole and a reamed hole bolt. Detailed Implementation

[0018] like Figures 1 to 3 As shown, a lifeboat jacking includes a bow jacking 1 and a back plate 2. The bow jacking 1 is welded to the back plate 2. The back plate 2 has several hinge holes 3, each with a hinge bolt 4. A matching nut 5 is located at the bottom of the hinge bolt 4. This device is installed on the bridge at the stern of the lifeboat. The unthreaded portion of the hinge bolt 4 passes through the hinge hole 3, while the threaded portion enters the bridge and engages with the nut 5. The close fit between the unthreaded portion of the hinge bolt 4 and the hinge hole 3 ensures that the device, once fixed to the bridge, will not tend to move and will not pose a risk of leakage.

[0019] The bow lifting base 1 includes an eye plate 11 and a base plate 12. The eye plate 11 and the base plate 12 are integrally formed, and no welding is required between the eye plate 11 and the base plate 12, which reduces the workload and improves the work efficiency. The eye plate 11 is located on top of the base plate 12, and the bottom of the base plate 12 is welded to the back plate 2. The eye plate 11 is provided with a through hole 13, which is used for hoisting.

[0020] The eye plate 11 is annular, and the top surface of the base plate 12 is arc-shaped to fit the eye plate 11. The bottom surface of the base plate 12 is flat, and both sides of the base plate 12 are inclined surfaces extending from the top surface to the bottom surface, and the two inclined surfaces are not symmetrical. The inclined surfaces are divided into longer inclined surfaces and shorter inclined surfaces. During installation, the longer inclined surface is located below the shorter inclined surface. Because the longer inclined surface needs to bear the weight of the device itself, having the longer inclined surface at the bottom increases the strength of the device.

[0021] The back plate 2 has a rectangular cross-section, and the hinge holes 3 are symmetrically distributed on both sides of the back plate 2. The hinge holes 3 on both sides are evenly distributed along the long side of the back plate 2. There are a total of 8 hinge holes 3, with 4 hinge holes 3 on each side of the back plate 2.

[0022] The two end faces of the eye plate 11 have a first plane of symmetry, and the base plate 12 has a second plane of symmetry, as shown in the figure. Figure 2 As shown in Figure A, both the first and second symmetry planes are in the same direction as the distribution of the reamed holes 3; and the first and second symmetry planes coincide. The coincidence of the first and second symmetry planes can effectively prevent uneven stress on the reamed hole bolts 4 and extend the service life of the reamed hole bolts 4.

[0023] Both sides of the inclined surface are tangent to the eye plate 11. The width of the base plate 12 is smaller than the width of the eye plate 11. The fact that the width of the eye plate 11 is greater than the width of the base plate 12 significantly increases the strength of the eye plate 11 and improves the stability of the device.

[0024] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
