Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, specifically relating to an auxiliary tooling for marking lashing bowls on roll-on / roll-off ships. Background Technology

[0002] On the deck of a roll-on / roll-off ship, there are usually tens of thousands of lashing bowls that need to be installed. Each lashing bowl installation location on the deck has a circular hole (this patent uses a circular hole radius of 55mm as an example). During the construction phase, the lashing bowls are installed upside down on the circular holes, and the center of the lashing bowl is required to be aligned with the center of the hole on the deck. However, when installed upside down, the circular hole is covered by the lashing bowl, making it impossible to precisely align the center of the lashing bowl with the center of the circular hole, resulting in extremely low installation efficiency. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an auxiliary tool for marking lashing bowls on roll-on / roll-off ships. This tool helps construction workers quickly mark the positioning lines of the lashing bowls on the deck where they need to be installed, facilitating the rapid and accurate alignment, positioning, and installation of the lashing bowls, greatly improving work efficiency, and is also cost-effective.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A tooling for marking lashing bowls on roll-on / roll-off ships includes a lashing bowl model and a limiting member. The top surface of the limiting member is fixed to the concave side of the lashing bowl model. The limiting member is located on one side of the central axis of the lashing bowl model and extends downward in the vertical direction. The lower end of the limiting member is located below the bottom surface of the lashing bowl model. In use, the limiting member is first inserted into an opening on the ship's deck, the lashing bowl model is fastened onto the deck, and the tooling is moved horizontally so that the two sides of the limiting member in the vertical direction rest against the edge of the opening.

[0005] Furthermore, the limiting member is an H-shaped frame limiting member.

[0006] Furthermore, the central axis of the crossbar in the H-shaped frame limiting member is located above the horizontal center line of the H-shaped frame limiting member.

[0007] Furthermore, the tooling also includes a handle, which is fixed to the convex surface of the binding bowl model.

[0008] Furthermore, the handle is U-shaped, and the vertical center line of the handle coincides with the central axis of the binding bowl model.

[0009] Furthermore, the transverse bar of the H-shaped frame limiting member is perpendicular to the width direction of the handle.

[0010] Furthermore, an arrow mark is provided on the convex surface of the binding bowl model. The arrow mark is located on the side of the H-shaped frame limiting member away from the central axis of the binding bowl model and is positioned opposite to the side of the handle thickness.

[0011] This utility model provides an auxiliary tooling for marking lashing bowls on roll-on / roll-off ships. The dimensions of the lashing bowl model are consistent with the specifications of the lashing bowl to be installed, ensuring that the drawn lashing bowl positioning line dimensions match the actual lashing bowl to be installed. The H-shaped frame limiting component is strong and reliable. Combined with the arrow markings on the surface of the lashing bowl model, the H-shaped frame limiting component is positioned to contact the edge of the circular hole on the deck along this direction. The lashing bowl model is then fastened onto the deck surface. The position of the edge of the lashing bowl model at this point is the position for the subsequent lashing bowl installation. A circle can be drawn on the deck along the edge of the lashing bowl using a stone pencil. The tooling has a simple overall structure, is easy to manufacture, convenient and quick to use, and produces accurate lashing bowl positioning lines, improving construction efficiency while ensuring lashing bowl installation accuracy at a low cost. The handle is easy to grip and use. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-3 As shown, a lashing aid for lashing bowls on a roll-on / roll-off ship includes a lashing bowl model 1 and a limiting member. The top surface of the limiting member is fixed to the concave side of the lashing bowl model 1. The limiting member is located on one side of the central axis of the lashing bowl model 1 and extends downward in the vertical direction. The lower end of the limiting member is located below the bottom surface of the lashing bowl model 1. In use, the limiting member is first inserted into an opening on the ship's deck, the lashing bowl model 1 is fastened onto the deck, and the tool is moved horizontally so that the two sides of the limiting member in the vertical direction rest against the edge of the opening.

[0018] In this embodiment, the limiting member is an H-shaped frame limiting member 2; the central axis of the crossbar in the H-shaped frame limiting member 2 is located above the horizontal center line of the H-shaped frame limiting member 2.

[0019] In this embodiment, the tooling also includes a handle 3, which is fixed to the convex surface of the binding bowl model 1; the handle 3 is U-shaped, and the vertical center line of the handle 3 coincides with the central axis of the binding bowl model 1; the transverse rod of the H-shaped frame limiting member 2 is perpendicular to the width direction of the handle 3.

[0020] Furthermore, an arrow mark 4 is provided on the convex surface of the binding bowl model 1. The arrow mark 4 is located on the side of the H-shaped frame limiting member 2 away from the central axis of the binding bowl model 1, and is positioned opposite to the thickness side of the handle 3.

[0021] In this embodiment, the lashing bowl model 1 is a carbon steel bowl with a diameter of 180mm, an inner height of 40mm, and a thickness of 5mm (the size and specifications of this lashing bowl are consistent with the lashing bowls that actually need to be installed on the roll-on / roll-off ship); the handle 3 is a round steel bar with a diameter of 8mm bent, and the upper handle position is a semi-circle with an outer radius of 52mm, and the lower part of both ends of the semi-circle is 60mm long; the H-shaped frame limiting member 2 is made of three 8mm round steel bars, and the limiting shape is "H". In this embodiment, the diameter of the opening at the lashing bowl installation position on the roll-on / roll-off ship deck is 55mm, the height of the H-shaped frame limiting member 2 is 70mm, the center distance between the two vertical round steel bars in the H-shaped frame limiting member 2 is 22mm, and the height direction of the H-shaped frame limiting member 2 extends 30mm below the horizontal plane of the lashing bowl model 1.

[0022] For ease of description, in Figure 3 In the schematic diagram of this fixture, the center line perpendicular to the U-shaped surface of the handle 3 is called the X-axis, and the center line parallel to the U-shaped surface of the handle 3 is called the Y-axis. The H-shaped frame limiting member 2 is positioned and installed perpendicular to the "Y" axis. The H-shaped frame limiting member 2 is bisected by the Y-axis, and the vertical distance between the H-shaped frame limiting member 2 and the X-axis along the Y-axis is 15mm. In addition, the arrow 4 indicates the direction along the Y-axis, and this arrow serves as the limiting direction during the use of the fixture. When using the fixture, hold the handle 3 and insert the H-shaped frame limiting member 2 into the hole opened on the deck. Attach the lashing bowl to the deck, and move the fixture along the direction of the arrow until the H-shaped frame limiting member 2 rests against the edge of the hole opened on the deck. Then, use a chalk to draw a circle on the deck along the edge of the lashing bowl. This circle is the later installation position of the lashing bowl.

[0023] Those skilled in the art should understand that the above description is merely a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
