Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a device and method for protecting a ship deck opening under material transportation conditions. Background Art

[0002] In the process of modern ship tower construction, large marine equipment, pipes and outfitting parts in each deck cabin will be lifted by crane or manually dragged to the corresponding cabin position before the cabin is covered. However, in the actual construction process, there is a risk of delayed delivery of equipment and materials. In order not to affect the progress of the tower construction of the hull structure, it is often the case that the cabin has been covered, but the equipment and materials in the cabin arrive at the factory late. Therefore, in order to facilitate the transportation of equipment and materials into the cabin, large openings are usually cut on the deck surface at the top of the ship's cabin for the import and export of equipment and materials. During the transportation or lifting of equipment and materials, such as Figure 1 As shown in the figure, due to wind and human operation factors, the equipment often swings during the hoisting process and hits the edge of the deck opening, or when materials such as cables and wire ropes are dragged into the cabin, they produce hard friction with the edge of the deck opening, such as Figure 2 As shown, the structure at the edge of the deck opening is damaged or deformed, and the equipment and materials transported into the cabin are also at risk of damage from impact or scratches. Currently, most shipbuilders deal with this problem by covering the equipment and materials entering the cabin with wooden / iron frames or protective covers to prevent damage to the equipment and materials and the edges of the deck openings caused by impact or friction. This method has the following problems: 1. The protective frames or protective covers are easily damaged by impact or friction, resulting in a high scrap rate. 2. The size of the protective frames or protective covers is designed according to the shape of the equipment and materials, and they are not reusable, resulting in high costs. 3. The edge of the deck opening will still be deformed or damaged by the collision of the protective frames, resulting in additional repair costs. Summary of the Invention

[0040] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0041] The present application provides a protection device for ship deck openings under material transportation conditions, such as Figures 3 to 14As shown, it includes a clamping and fastening component 1, a protective roller 2 and a detachable roller component 3;

[0042] The clamping and fastening component 1 includes a U-shaped clamping groove 101 and a first fixed roller 102. The U-shaped clamping groove 101 can be clamped and fixed on the ship deck 01. The first fixed roller 102 is L-shaped. One side of the first fixed roller 102 is vertically fixed to the outside of the bottom of the U-shaped clamping groove 101, and the other side of the first fixed roller 102 is parallel to the bottom of the U-shaped clamping groove 101. When the U-shaped clamping groove is clamped on the bottom surface of the groove on the ship deck 01, the first fixed roller 102 is located in the opening 02; the protective roller 2 can be mounted on the first fixed roller 102 and roll;

[0043] The detachable roller component 3 includes a U-shaped slot 301 and a second fixed roller 302. The second fixed roller 302 is vertically fixed to the side of the U-shaped slot 301. The U-shaped slot 301 can be clamped at the bottom of the U-shaped clamping groove 101. When the U-shaped slot 301 is clamped at the bottom of the U-shaped clamping groove 101, the second fixed roller 302 and the first fixed roller 102 are on the same side. The end of the second fixed roller 302 away from the U-shaped slot 301 is against the end of the first fixed roller 102 to limit the axial movement of the protective roller 2 mounted on the first fixed roller 102.

[0044] In this embodiment, the clamping and fastening component 1 also includes a fastening bolt 105, which is threadedly connected to the side of the U-shaped clamping groove 101. When the U-shaped clamping groove 101 is clamped on the ship deck 01, the fastening bolt 105 can be abutted against the ship deck 01 so that the U-shaped clamping groove 101 can be stably fixed on the ship deck 01. In order to ensure the stability of the U-shaped clamping groove 101, two fastening bolts 105 are provided on the same side of the U-shaped clamping groove 101. The sides of the U-shaped clamping groove 101 are both provided with threaded holes 104 that match the fastening bolts 105, so as to facilitate bolt fastening under both positive clamping and reverse clamping conditions of the protective device. By providing the fastening bolts 105, the clamping and fastening component 1 can be clamped on ship decks 01 of different thicknesses, thereby expanding the scope of application of the protective device of this application.

[0045] The clamping and fastening component 1 also includes a limit pin 103 fixed to the outside of the bottom of the U-shaped clamping groove 101. The limit pin 103 is arranged on the lower side of the first fixed roller 102. A limit slot 303 is provided on the side of the U-shaped clamping groove 301. The limit slot 303 is an inverted U-shape with an opening downward. The limit slot 303 is arranged on the same side as the second fixed roller 302. When the U-shaped clamping groove 301 is clamped to the bottom of the U-shaped clamping groove 101, the limit pin 103 is clamped on the limit slot 303 to fix the connection between the U-shaped clamping groove 101 and the U-shaped clamping groove 301. When the detachable roller component 3 is inserted into the clamping and fastening component 1, the U-shaped clamping groove 301 is lifted. After the U-shaped clamping groove 301 is in place, the limit pin 103 is clamped into the limit slot 303, thereby preventing the protective roller 2 from shifting and detaching when the protective device is in use.

[0046] Protective roller 2 consists of a small roller 201 with a diameter of 40-60 mm and a large roller 202 with a diameter of 70-90 mm. When hoisting equipment 03 through the opening, protective roller 2 is the small roller 201. When pulling rope-like object 04 through the opening, protective roller 2 is the large roller 202. In this embodiment, protective roller 2 is made of soft polyurethane. The diameter of small roller 201 is 50 mm, and the diameter of protective roller 2 is 80 mm.

[0047] The U-shaped clamping groove 101 is made of 10mm thick Q235A steel, and the groove spacing of the U-shaped clamping groove 101 is 55mm to adapt to the ship deck with a thickness range of 0 to 50mm. The first fixed roller 102 is made of 15mm diameter Q235A round steel, the limit pin is made of 10mm diameter Q235A round steel, and the fastening bolt 105 is a metric M12*1.25 bolt.

[0048] The present application provides a method for protecting a ship deck opening under material transportation conditions, comprising the following steps:

[0049] Step 1: Select the protective roller model according to the actual working conditions, assemble the clamping fastening component 1, the protective roller 2 and the detachable roller component 3 into place to assemble the protective device for the above-mentioned ship deck opening under the material transportation working conditions;

[0050] Step 2: Clamp the complete protective device onto the ship deck 01 at the four edges of the opening and tighten the fastening bolts 105 to secure the protective device.

[0051] Step 3: Hoisting equipment 03 enters / exits the cabin or dragging rope-like object 04 into / out of the cabin, equipment 03 or rope-like object 04 abuts against protective roller 2 and moves slowly under the guidance of protective roller 2;

[0052] Step 4: After the operation is completed, remove the protective device of the above-mentioned ship deck opening under the material transportation working condition.

[0053] Define the lifting equipment as operating condition one, and the dragging of the rope-like object as operating condition two. When the material transport operating condition is operating condition one, the protective roller 2 in step 1 is a small roller 201 to minimize the space occupied by the protective device in the deck opening. In step 2, when the protective device is clamped to the hull deck 01, the fastening bolts are located above the hull deck 01. This allows the protective device to buffer the impact caused by the equipment hoisting and swaying and provide rolling guidance in step 3. When the material transport operating condition is operating condition two, the protective roller 2 in step 1 is a large roller 202. In step 2, when the protective device is clamped to the hull deck 01, the fastening bolts 105 are located below the hull deck 01. This facilitates the rope-like object 04 to move up and down against the roller when entering or exiting the cabin. The protective device can prevent hard friction between the rope-like object 04 and the deck edge, making the dragging process easier and more convenient.

[0054] In step 2, define the edge length of the deck opening as A and the width of the protective device as B. Then, the number of protective fixtures required to be installed on one side of the deck opening is an integer of A / B+1, and the protective devices on one side of the deck opening are evenly distributed to ensure that the equipment can be attached to at least two protective fixtures on one side during lifting, thereby ensuring the stability of the equipment during the lifting process.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solutions of the present invention. They should all be included in the scope of the technical solutions for which protection is sought in the present invention.
