Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a combined equipment transport device for shipbuilding. Background Technology

[0002] During shipbuilding, heavy equipment such as air caps needs to be frequently moved inside cabins. Traditional methods rely on cranes or manual labor. However, with the application of modular shipbuilding technology, the hull sections are completed first, resulting in enclosed cabins with narrow passageways, making it impossible for cranes to enter and lift equipment. Manual handling is inefficient, poses significant safety hazards, and is labor-intensive. Existing rail-mounted transport devices have fixed structures, cannot be modularized and expanded, and cannot adapt to the passageways of different ship cabins. Therefore, there is an urgent need for a modular equipment transport device that is easy to carry, assemble and disassemble, has a safe structure, and can be adjusted and expanded according to the spatial environment. Summary of the Invention

[0003] The technical problems to be solved by this invention are as follows: 1. Overcoming the defect that traditional cranes cannot enter narrow cabin passages; 2. Solving the problems of low efficiency and poor safety of manual handling of heavy equipment; 3. Realizing the rapid assembly and disassembly of tooling, improving the portability of equipment transportation devices, and adapting to the needs of different cabin layouts.

[0004] This application proposes a combined equipment transport device for shipbuilding, including a rail system and a fixed lifting system;

[0005] The fixed lifting system is installed on the structural beam of the ship's hull. The fixed lifting system has suspension holes for suspending lifting devices, thereby enabling the lifting, lowering and placement of equipment.

[0006] The guide rail system includes a support structure, a rail module, and a sliding component;

[0007] The support structure includes several support modules. Each support module includes two support structure columns and connecting members. The two support structure columns are fixedly connected to each other through the connecting members, and adjacent support modules are fixedly connected to each other through the connecting members, so that the support modules can be expanded to form a support structure. The width of the support structure can be adjusted by selecting the connection position when the support structure columns and connecting members are combined, so as to adapt to the width of different ship compartment passages.

[0008] The track module is installed on top of the support structure, and the sliding component is installed inside the track module, and the sliding component can slide inside the track module.

[0009] Furthermore, a pad is horizontally installed at the bottom of the support structure column, and a groove structure is formed at the top of the support structure column.

[0010] Furthermore, a front auxiliary steel plate and a rear auxiliary steel plate are fixedly installed in the front and rear directions of the connecting member, so that adjacent connecting members are fixedly connected by the auxiliary steel plates.

[0011] Furthermore, the track module includes several channel steels, which are supported by the groove structure at the top of the support structure column, so that the channel steels are arranged and installed at the top of the support structure column.

[0012] Furthermore, a first rubber gasket is installed between the channel steel and the groove structure at the top of the supporting structure column.

[0013] Furthermore, the sliding assembly includes a load-bearing plate and at least one pair of pulley bases; the pulley bases are symmetrically installed in the channel steels distributed on both sides, and the load-bearing plate is arranged on the surface of the pulley bases. When the pulley bases move within the channel steels, they can drive the load-bearing plate to move.

[0014] Furthermore, the pulley base includes two main pulleys and two limiting guide wheels. The main pulleys contact the inner bottom of the channel steel and roll inside the channel steel to drive the sliding assembly to move. The limiting guide wheels contact the inner walls on both sides of the channel steel respectively, playing a limiting and guiding role to prevent the pulley base from rubbing against the channel steel.

[0015] Furthermore, the fixed lifting system includes a U-shaped steel plate and two L-shaped steel plates. The vertical edge of the L-shaped steel plate abuts against the bottom plate of the hull structural beam. The U-shaped steel plate is used to connect the two L-shaped steel plates so that the two L-shaped steel plates can be clamped onto the hull structural beam.

[0016] Furthermore, the L-shaped steel plate has two suspension holes for suspending a lifting device, thereby enabling the lifting, lowering, and arrangement of heavy equipment.

[0017] The advantages and positive effects of this invention are:

[0018] 1. Portable design of the present invention: The structure and weight of the fixed lifting system, track module, sliding component and individual support module are all controllable. The guide rail system and fixed lifting system can be quickly assembled and disassembled by bolt connection, and the size of the disassembled steel plate does not exceed 1000×600×300mm, which is convenient for manual handling to any position in the compartment.

[0019] 2. Flexible deployment of the invention: The modular expansion structure design allows the combined equipment transportation device of the invention to be deployed and used without being limited by the passageway space, and can adapt to different compartment passages of different ships; moreover, the bolt connection assembly method is convenient and quick, simple to operate, and can be deployed in a short time, improving work efficiency.

[0020] 3. This invention is highly efficient and safe: By using a sliding track, the drag resistance of manual labor is reduced, greatly improving the handling efficiency; and by using a guide rail system and a fixed lifting system, the movement and lifting of heavy equipment can be achieved, which is more stable and safer than manual handling, reducing the risk of accidents.

[0021] 4. The invention has low manufacturing and maintenance costs: the materials used are all ordinary steel plates, with no special materials; the modular structural design can be combined, expanded, and transformed to avoid repeated construction; at the same time, the modular components can be reused and replaced, reducing maintenance costs.

In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this invention. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this invention, and should not be construed as limiting the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0032] like Figure 1-7 As shown, this embodiment provides a combined equipment transportation device for shipbuilding, including a guide rail system and a fixed lifting system;

[0033] The fixed lifting system is installed on the hull structural beam 1. The fixed lifting system has suspension holes for suspending lifting devices, thereby realizing the lifting and lowering and arrangement of equipment.

[0034] The guide rail system includes a support structure, a rail module, and a sliding component;

[0035] The support structure includes several support modules. Each support module includes two support structure columns 14 and a connecting member 15. The two support structure columns 14 are fixedly connected to each other through the connecting member 15. Adjacent support modules are fixedly connected to each other through the connecting member 15, so that the support modules can be expanded to form a support structure. The width of the support structure can be adjusted by selecting the connection position when the support structure columns 14 and the connecting member 15 are combined, so as to adapt to the width of different ship compartment passages.

[0036] The track module is installed on top of the support structure, and the sliding component is installed inside the track module, and the sliding component can slide inside the track module.

[0037] A pad 17 is horizontally installed at the bottom of the support structure column 14, and a groove structure is formed at the top of the support structure column 14; a front auxiliary steel plate 20 and a rear auxiliary steel plate 21 are fixedly installed in the front and rear directions of the connecting member 15, so that adjacent connecting members 15 are fixedly connected by the auxiliary steel plates; specifically, the bolt holes on the rear auxiliary steel plate 21 of the connecting member 15 are aligned with the bolt holes on the front auxiliary steel plate 20 of another connecting member 15, and the support structure connecting bolt 19 is inserted and the support structure connecting nut 18 is tightened.

[0038] The track module includes several channel steels 13, which are supported by the groove structure at the top of the supporting structure column 14, so that the channel steels 13 are arranged and installed on the top of the supporting structure column 14; a first rubber pad 11 is installed between the channel steel 13 and the groove structure at the top of the supporting structure column 14; specifically, the track module is a parallel metal track composed of two channel steels 13, the shape of the channel steel 13 is adapted to the shape of the groove structure on the upper part of the supporting structure column 14, so that the track module can be stably placed on the upper part of the supporting structure; the first rubber pad 11 is spaced between the channel steel 13 and the groove, which can play a role in anti-slip and protection;

[0039] The sliding assembly includes a load-bearing plate 9 and at least one pair of pulley bases 12. The pulley bases 12 are symmetrically installed in the channel steels 13 distributed on both sides. The load-bearing plate 9 is arranged on the surface of the pulley base 12. When the pulley base 12 moves within the channel steels 13, it can drive the load-bearing plate 9 to move. The pulley base 12 includes two main pulleys 23 and two limiting guide wheels 24. The main pulleys 23 are in contact with the inner bottom of the channel steels 13 and roll within the channel steels 13 to drive the sliding assembly to move. The limiting guide wheels 24 are in contact with the inner walls on both sides of the channel steels 13, playing a limiting and guiding role to prevent the pulley base 12 from rubbing against the channel steels 13.

[0040] It should be noted that in this embodiment, the sliding assembly consists of a load-bearing plate 9, four pulley bases 12, and four second rubber pads 10. The load-bearing plate 9 is not fixedly connected to the pulley bases 12, but is placed directly on the support panel 22 of the pulley base 12 in use with the second rubber pads 10. This arrangement allows the sliding assembly to adapt to different track widths without repeated manufacturing. The pulley base 12 has two main pulleys 23 and two limiting guide wheels 24. The main pulleys 23 directly contact the inner bottom of the channel steel 13 and roll inside the channel steel 13 to drive the sliding assembly to move. The two limiting guide wheels 24 contact the inner walls on both sides of the channel steel 13 respectively, playing a limiting and guiding role to prevent the pulley base 12 from rubbing against the channel steel 13.

[0041] The fixed lifting system includes a U-shaped steel plate 2 and two L-shaped steel plates 3. The vertical edge of the L-shaped steel plate abuts against the lower base plate of the hull structural beam 1. The U-shaped steel plate 2 connects the two L-shaped steel plates 3, allowing them to be clamped onto the hull structural beam 1. Specifically, the fixed lifting system is arranged on the hull structural beam 1 and is formed by connecting and fixing the U-shaped steel plate 2 and the two L-shaped steel plates 3 with bolts and fasteners 6. The vertical edge of the L-shaped steel plate abuts against the lower base plate of the hull structural beam 1. An adjusting pad 4 and a third rubber pad 5 are spaced between the L-shaped steel plate and the hull structural beam 1 to distribute the load and prevent slippage. The U-shaped steel plate 2 is mainly used to connect the two L-shaped steel plates 3. A fourth rubber pad 7 and an adjusting pad 8 are also arranged between the longitudinal plates. On the one hand, they protect the hull structural beam 1, and on the other hand, they can work with the U-shaped steel plate 2 to clamp and fix the L-shaped steel plate 3, ensuring that the two L-shaped steel plates 3 can be clamped on the hull structural beam 1. The L-shaped steel plate 3 has two suspension holes for suspending lifting devices such as pulleys and hand-cranked hoists, thereby realizing the lifting, lowering and placement of heavy equipment. This combined modular fixed lifting system allows for the combination of L-shaped steel plates 3 and U-shaped steel plates 2 of different sizes to adapt to different types of structural beams. With the help of adjusting pads 8 of different thicknesses for clamping and fixing, and the fourth rubber pad 7 for anti-slip and protection, it can be used on multiple ships.

[0042] As an example, in this embodiment, such as Figure 1 As shown, the fixed lifting system is arranged on the hull structural beam 1, and includes a U-shaped steel plate 2 and two L-shaped steel plates 3, which are connected and fixed by connecting bolts 6; the specific installation steps are as follows:

[0043] Step 1: Place the third rubber pad 5 and the lower pad 4 at the position where the fixed lifting system needs to be arranged along the lower edge of the hull structure beam 1;

[0044] Step 2: Place the notched side of the support edge of the two L-shaped steel plates 3 against the lower pads 4 on both sides of the hull structure beam 1, align the bolt holes of the U-shaped steel plate 2 with the bolt holes on the two L-shaped steel plates 3, and tighten them with four connecting bolts 6 to connect the two L-shaped steel plates 3.

[0045] Step 3: Place the fourth rubber pad 7 on both sides of the longitudinal structure of the hull beam 1. Then, squeeze an adjustment pad 8 of appropriate thickness between the fourth rubber pad 7 and the L-shaped steel plate 3, so that the fixed lifting system is clamped on the hull beam 1, and the assembly and fixing are completed. Finally, hang a hand-cranked hoist or other device at the suspension hole on the transverse side of the L-shaped steel plate 3 to carry out the lifting and lowering operation of heavy equipment.

[0046] like Figure 2As shown, the guide rail system consists of three parts: a support structure, a rail module, and a sliding assembly. The installation steps for the guide rail system are as follows:

[0047] Step 1: Place two support structure columns 14 at the entrance of the cabin passage, and stabilize them on the cabin passage floor by means of the pads 17 welded to their bottoms; align the bolt holes on the connecting component 15 with the bolt holes on the left and right support structure columns 14, and connect and tighten them with support structure combination bolts 16 to assemble a support module; repeat this step to assemble an appropriate number of support modules to form a support structure.

[0048] Step 2: Align the bolt holes on the rear auxiliary steel plate 21 of one support structure with the bolt holes on the front auxiliary steel plate 20 of the other support structure, insert the support structure connecting bolts 19 and tighten the support structure connecting nuts 18 to connect the two support structures; repeat this step to connect an appropriate number of support structures according to the length of the compartment passage.

[0049] Step 3: Place the first rubber pad 11 in the groove at the top of each support column 14, and then insert the channel steel 13 into the groove at the top of two adjacent support columns 14 to set up a guide rail between the two support structures. Since the first rubber pad 11 is elastic, it can play an anti-slip role and also tighten the channel steel 13. Repeat this step to arrange the channel steel 13 between each support structure, aligning the two adjacent channel steels 13 without leaving gaps, thereby assembling the guide rail structure.

[0050] Step four: Place the pulley base 12 inside the channel steel 13, so that the main pulley 23 is in direct contact with the inner bottom surface of the channel steel 13, and at the same time, make the two limiting guide wheels 24 contact the inner walls on both sides of the channel steel 13 respectively, so as to achieve stable sliding; after arranging the four pulley bases, place the load-bearing plate 9 flat on the support panel 22 of the pulley base 12, and install the second rubber pad 10 between the load-bearing plate 9 and the support panel 22 to support the heavy equipment to be moved.

[0051] The steps for using this device are as follows:

[0052] Step 1: Assemble and fix the hoisting system on the hull structural beam 1 at the heavy equipment hoisting position at the entrance of the cabin passage;

[0053] Step two: Assemble the guide rail system in the cabin passageway, with the guide rail system leading directly to the destination of the heavy equipment;

[0054] Step 3: Using the fixed hoisting system and hand hoist, lift the heavy equipment, move it in the air to the top of the load-bearing plate 9 using the hoisting rope, and then use the hand hoist to lower the heavy equipment onto the load-bearing plate 9.

[0055] Step 4: Disassemble the fixed hoisting system and reinstall the fixed hoisting system on the hull structural beam 1 at the destination of the heavy equipment;

[0056] Step 5: Push the sliding assembly to move the heavy equipment to the desired position;

[0057] Step 6: Using the fixed hoisting system and hand hoist, lift the heavy equipment from the load-bearing plate 9, move the heavy equipment to its installation position in the air using hoisting ropes, and then use the hand hoist to lower the heavy equipment for installation.

[0058] Step 7: Disassemble the fixed hoisting system and guide rail system to complete the transportation of heavy equipment.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
