Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a quick decoupling device and a decoupling method for assisting in the installation of ship guides. Background Art

[0002] The guides on container ships are important components on container ships, which can play a guiding role in loading and unloading containers. During the construction of container ships, it is necessary to vertically install the guides at the edge of the transverse bulkhead of the container ship. Therefore, a crane is required to lift one end of the guide and drive it towards the hull, and then the installation and positioning of the guide are carried out. However, during the entire installation process, the crane needs to always hook the guide, and the hook of the crane can only be disassembled from the guide after the guide is installed. This seriously occupies the crane resources, making the crane unable to perform other tasks, affecting the installation speed of the guide, and also reducing the construction efficiency of the container ship. Summary of the Invention

[0003] In view of this, the purpose of the present application is to provide a quick decoupling device and a decoupling method for assisting in the installation of ship guides, so as to solve the problem that during the installation of the guide on a container ship, after the crane transports the guide to the designated position, it still needs to keep the state of hooking the guide for a long time until the guide is installed, which causes the occupation of crane resources and reduces the installation efficiency of the guide.

[0004] The first aspect of the present invention provides a quick decoupling device for assisting in the installation of ship guides. The guide is installed on the side of the ship bulkhead, and a deck is provided at the top of the ship bulkhead. Among them, the quick decoupling device for assisting in the installation of ship guides includes:

[0005] A decoupling fixing member is formed with a lifting portion penetrating through its main body for the hook of the lifting device to extend into; one end of the decoupling fixing member is formed as a first connecting portion connected to the end of the guide in the length direction, and the other end of the decoupling fixing member is formed as a second connecting portion that can be fixed on the top of the deck;

[0006] The guide installed with the decoupling fixing member is transported by the lifting device to the side of the ship bulkhead. When the second connecting portion is fixed on the top of the deck, the hook disengages from the lifting portion.

[0007] Preferably, the guide installed on the ship bulkhead is vertically arranged, and the decoupling fixing member is arranged at the top of the guide in a vertical state;

[0008] The first connecting portion extends towards the guide, and the second connecting portion has the same extending direction as the first connecting portion, so that the decoupling fixing member installed on the deck and the guide is formed into an inverted U-shaped structure.

[0009] Preferably, the extension dimension of the first connecting part is greater than that of the second connecting part.

[0010] Preferably, the lifting part is arranged above the first connecting part;

[0011] In the vertical direction, the lifting part is correspondingly arranged with the center of gravity of the guide rail, so that when the lifting device transports the guide rail, the guide rail always remains in a vertical state.

[0012] Preferably, the cross-section of the guide rail in a direction perpendicular to its length is formed in a T shape;

[0013] The first connecting part is formed into a plate-like structure. When the guide rail is arranged on the side of the ship bulkhead, at least a part of the first connecting part is attached to the vertically arranged part of the T-shaped structure, and the vertically arranged part of the T-shaped structure protrudes away from the ship bulkhead.

[0014] Preferably, one end of the guide rail connected to the first connecting part is formed into a guiding part; when the guide rail is arranged on the side of the ship bulkhead, the dimension of the cross-section of the guiding part in a direction perpendicular to its height gradually decreases from top to bottom, so that the side wall of the guiding part close to the ship bulkhead is inclined;

[0015] Along the extension direction of the first connecting part, the dimension of the first connecting part in the horizontal direction gradually decreases, so that one side of the first connecting part is formed into an inclined side and has the same slope as the side wall of the guiding part close to the ship bulkhead.

[0016] Preferably, the hook disengaging fixing part is further formed with an avoiding part arranged between the first connecting part and the second connecting part;

[0017] When the second connecting part is fixed to the top of the deck, a predetermined distance is formed between the avoiding part and the deck, and the predetermined distance is 60 mm to 100 mm.

[0018] Preferably, the dimension of the avoiding part in the horizontal direction is 100 mm to 400 mm.

[0019] Preferably, the avoiding part is formed into a structure with adjustable length to adjust the distance between the first connecting part and the second connecting part.

[0020] The second aspect of the present invention provides a hook disengaging method, which is applied to the quick hook disengaging device for assisting the installation of ship guide rails including any one of the above technical solutions. The hook disengaging method includes:

[0021] S1. Connect the first connecting part with one end in the length direction of the guide rail;

[0022] S2. The hook extends into the lifting part and lifts the guide rail to a vertical state.

[0023] S3. The lifting device transports the guide rail in the vertical state to the side of the ship bulkhead and makes the second connecting part lap on the top of the deck.

[0024] S4. After the second connecting part is spot-welded and fixed to the deck, the hook disengages from the lifting part.

[0025] S5. Fix the guide rail vertically to the side of the ship bulkhead.

[0026] S6. After the connection between the guide rail and the ship bulkhead is completed, remove the hook fixing part.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] The quick-hook device for assisting in the installation of ship guide rails of the present invention can be installed on the guide rail and transported to the side of the ship bulkhead together with the guide rail. When the hook fixing part is fixed to the deck, the hook can be disengaged, so as to avoid occupying the resources of the lifting device for a long time and enable it to continue to perform tasks such as transporting the guide rail, thereby improving the installation efficiency of the guide rail; in addition, implementing the hook disengaging method of the quick-hook device for assisting in the installation of ship guide rails can shorten the time for the hook to lift the guide rail, so as to accelerate the hook disengaging speed of the lifting device, enabling the lifting equipment to perform other operations, thereby shortening the working hours, saving costs, accelerating the shipbuilding speed, and improving the shipbuilding efficiency.

[0045] According to the present invention, there is provided a quick decoupling device for assisting in the installation of a ship guide rail, which includes a decoupling fixing member 10.

[0046] Example 1

[0047] In the following, the specific structures of the above components of the quick-release hook device for assisting in the installation of ship guides according to this embodiment will be described.

[0048] In this embodiment, as Figure 2 shown, a plurality of vertically arranged guides 20 need to be installed on the side of the ship bulkhead 30. There is a deck 40 provided at the top of the ship bulkhead 30. The quick-release hook fixing member 10 is formed with a lifting portion 11 penetrating through its main body for the hook of the lifting device to extend into. The lifting portion 11 can be formed into a hole-like structure such as a circle or a rectangle, as long as it can ensure the hook to extend into. Specifically, the guides 20 installed on the ship bulkhead 30 are vertically arranged, and the quick-release hook fixing member 10 is provided at the top of the guide 20 in a vertical state, so that the hook of the lifting device indirectly lifts and transports the guide 20 by lifting the quick-release hook fixing member 10. In the embodiment, the lifting device can be a crane.

[0049] In this embodiment, after the guide 20 installed with the quick-release hook fixing member 10 is transported to the side of the ship bulkhead 30 by the lifting device, when the second connecting portion 13 is fixed to the top of the deck 40, the hook disengages from the lifting portion 11, so that the guide 20 is positioned at the side of the ship bulkhead 30 through the quick-release hook fixing member 10. At this time, the guide 20 can be integrally installed on the ship bulkhead 30 without the lifting device continuously hooking the guide 20. The lifting device can unhook and perform other operations, such as transporting a new guide to the side of the ship bulkhead 30.

[0050] In this embodiment, as Figure 1 and Figure 2 shown, one end of the quick-release hook fixing member 10 is formed into a first connecting portion 12 connected to the end of the guide 20 in the length direction, and the other end of the quick-release hook fixing member 10 is formed into a second connecting portion 13 capable of being fixed to the top of the deck 40; specifically, the first connecting portion 12 extends towards the guide 20, and the second connecting portion 13 has the same extending direction as the first connecting portion 12, so that the quick-release hook fixing member 10 installed on the deck 40 and the guide 20 is formed into an inverted U-shaped structure. The quick-release hook fixing member 10 is preferably formed into a plate-like structure for facilitating its fixation on the deck 40 (the bottom edge of the second connecting portion 13 is connected to the deck 40, and the connection method can be welding, such as spot welding, for facilitating the subsequent disassembly of the quick-release hook fixing member 10); the groove portion on the U-shaped structure can reduce the weight of the quick-release hook fixing member 10 to reduce the load of the lifting device.

[0051] In a preferred embodiment, as Figure 1 and Figure 2 shown, the extending dimension of the first connecting portion 12 is greater than the extending dimension of the second connecting portion 13, thereby increasing the connection area between the first connecting portion 12 and the guide 20 (i.e., Figure 2(the shaded area in it), so as to improve the connection firmness between the decoupling fixture 10 and the guide rail 20. In this embodiment, the preferably extended dimension of the first connecting portion 12 is 235 mm. If the extended dimension of the first connecting portion 12 is too long, the assembly time cost of the first connecting portion 12 and the guide rail 20 will increase, wasting resources; the preferably extended dimension of the second connecting portion 13 is 85 mm. If the extended dimension of the second connecting portion 13 is too long, after the hook is decoupled, the stability of the decoupling fixture 10 for fixing the guide rail 20 will decrease.

[0052] In addition, in a preferred embodiment, the lifting portion 11 is arranged above the first connecting portion 12. Specifically, along the vertical direction, the lifting portion 11 is correspondingly arranged with the center of gravity of the guide rail 20, so that when the lifting device transports the guide rail 20, the guide rail 20 always remains in a vertical state, so as to improve the safety of the lifting device in transporting the guide rail 20 (since the guide rail 20 is relatively long, if the guide rail 20 is skewed during the transportation process of the guide rail 20, the attitude of the guide rail 20 in the air is not easy to control, easily causing accidents). In addition, the guide rail 20 transported in a vertical state is consistent with its vertically installed attitude, thereby improving the positioning accuracy of the lifting device in transportation, so as to reduce the installation difficulty of the guide rail 20.

[0053] In the embodiment, as Figure 2 shown, the cross-section of the guide rail 20 in the direction perpendicular to its length forms a T shape (that is, the cross-sectional shape is formed by two structures of "─" and "│"); the first connecting portion 12 is formed into a plate-like structure, and the plate surface of the plate-like structure is connected to the guide rail 20, which can increase the contact area between the first connecting portion 12 and the guide rail 20, thereby improving the connection stability. Specifically, when the guide rail 20 is arranged on the side of the ship bulkhead 30, at least part of the first connecting portion 12 is attached to the vertically arranged part (that is, the structure in the shape of "│") in the T-shaped structure, and the vertically arranged part in the T-shaped structure protrudes away from the ship bulkhead 30.

[0054] In this embodiment, as Figure 2 shown, one end of the guide rail 20 connected to the first connecting portion 12 is formed into a guiding portion 21, so as to facilitate the components installed on the guide rail 20 to smoothly enter the guide rail 20; when the guide rail 20 is arranged on the side of the ship bulkhead 30, the size of the cross-section of the guiding portion 21 in the direction perpendicular to its height gradually decreases from top to bottom (that is, both the "─" and "│" parts of the structure gradually decrease), so that the side wall of the guiding portion 21 close to the ship bulkhead 30 (that is, the side wall formed by a plurality of cross-sectional structures in the shape of "─") is inclined; along the extending direction of the first connecting portion 12, the size of the first connecting portion 12 in the horizontal direction gradually decreases, so that one side of the first connecting portion 12 is formed into an inclined side and has the same slope as the side wall of the guiding portion 21 close to the ship bulkhead 30, thereby conforming to the inclined guiding portion 21 in a profiling manner, so as to improve the connection reliability between the decoupling fixture 10 and the guide rail 20.

[0055] In addition, in this embodiment, as Figure 1 and Figure 2 shown, the decoupling fixing member 10 is further formed with an avoidance portion 14 disposed between the first connecting portion 12 and the second connecting portion 13; when the second connecting portion 13 is fixed to the top of the deck 40, a predetermined distance is formed between the avoidance portion 14 and the deck 40, so as to facilitate the connection and disassembly of the second connecting portion 13 and the deck 40, such that the second connecting portion 13 can be installed close to the edge of the deck 40, which helps the positioning and installation of the second connecting portion 13 and the deck 40.

[0056] Embodiment Two

[0057] The weighing device of this embodiment is an improvement based on Embodiment One, and the technical content disclosed in Embodiment One will not be described repeatedly. The content disclosed in Embodiment One also belongs to the content disclosed in this Embodiment Two.

[0058] In this embodiment, as Figure 3 and Figure 4 shown, an installation groove 41 is provided at the edge position of the deck 40. Compared with Embodiment One, the size of the avoidance portion 14 in the horizontal direction and the predetermined distance between it and the deck 40 need to be increased corresponding to the size of the installation groove 41 to avoid the installation groove 41. In this embodiment, the predetermined distance is preferably 60 mm to 100 mm. The size of the avoidance portion 14 in the horizontal direction is 100 mm to 400 mm, for example, 330 mm. The specific size of the avoidance portion 14 can be adaptively adjusted according to the size of the installation groove 41 and its set position.

[0059] Embodiment Three

[0060] The weighing device of this embodiment is an improvement based on Embodiment Two, and the technical content disclosed in Embodiment Two will not be described repeatedly. The content disclosed in Embodiment Two also belongs to the content disclosed in this Embodiment Three.

[0061] In this embodiment, the avoidance portion is formed into a structure with adjustable length to adjust the distance between the first connecting portion and the second connecting portion. For example, the decoupling fixing member is formed into a split plate-like structure, and the first connecting portion and the second connecting portion are respectively disposed on different plate-like structures, and the two plate-like structures are slidably connected. Specifically, a sliding groove is provided on any one of the two plate-like structures, and a slider capable of sliding in the sliding groove is provided on the other plate-like structure. During the sliding of the slider in the sliding groove, the distance between the first connecting portion and the second connecting portion can be adjusted, such that the installer can adjust the length dimension of the avoidance portion in the horizontal direction according to the actual on-site situation of the guide rail installation position to avoid the installation groove or other structures on the deck and ensure the effective connection between the second connecting portion and the deck.

[0062] In addition, in this embodiment, a fastener is also provided on the length-adjustable avoidance portion for locking and fixing the avoidance portion after the size adjustment is completed. For example, the fastener is formed as a bolt and nut penetrating through the above-mentioned plate-like structure, as long as the relative positions of the first connecting portion and the second connecting portion can be fixed.

[0063] The structure of the quick-release hook device for assisting in the installation of ship guides according to the present invention is simple, light in weight, low in cost, and convenient for disassembly and assembly. It can be installed on the guide rail and transported to the side of the ship bulkhead together with the guide rail. When the release hook fixing member is fixed to the deck, the hook can be released to avoid occupying the hoisting device resources for a long time, enabling it to continue to perform tasks such as transporting the guide rail, thereby improving the installation efficiency of the guide rail.

[0064] A release hook method according to the second aspect of the present invention is applied to the implementation of the above-mentioned quick-release hook device for assisting in the installation of ship guides.

[0065] In this embodiment, the release hook method includes:

[0066] S1. Connect the first connecting portion to one end in the length direction of the guide rail. Preferably, the first connecting portion is fully welded to the entire circumference of the conduit to improve the connection reliability between the release hook fixing member and the guide rail.

[0067] S2. The hook extends into the lifting portion and lifts the guide rail to a vertical state.

[0068] S3. The hoisting device transports the vertically placed guide rail to the side of the ship bulkhead, and makes the second connecting portion overlap on the top of the deck. The final transportation position of each guide rail corresponds to its actual installation position.

[0069] S4. After the second connecting portion is spot-welded and fixed to the deck, the hook is released from the lifting portion, so that the hoisting device can perform other hoisting tasks and does not need to continue to participate in the installation process of this guide rail.

[0070] S5. The guide rail is positioned by the release hook fixing member. At this time, the guide rail can be vertically fixed to the side of the ship bulkhead to complete the connection between the guide rail and the ship bulkhead. The connection method is preferably welding.

[0071] S6. After the connection between the guide rail and the ship bulkhead is completed, the release hook fixing member is removed.

[0072] The release hook method according to the present invention is simple to operate, can effectively shorten the time for the hook to lift the guide rail, so as to accelerate the release speed of the hoisting device, enabling the hoisting equipment to perform other operations, thereby shortening the working hours, saving costs, and further accelerating the shipbuilding speed and improving the shipbuilding efficiency.

[0073] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that any person skilled in the art within the technical scope disclosed by the present application can still modify the technical solutions described in the foregoing embodiments, or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
