Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine equipment technology, and in particular to a hook storage base. Background Technology
[0002] Currently, most heavy-lift vessels at home and abroad are equipped with heavy-duty cranes ranging from 100 tons to less than 500 tons to meet the lifting needs of oversized and overweight cargoes. The heavy-duty crane itself needs to have a super strong hook that can lift a maximum weight of 500 tons. However, ships are subject to large waves and vibrations at sea. If a hook weighing about 7.8 tons is allowed to sway in the air, it would be quite dangerous. Cranes usually have a storage device under the boom to store the hook.
[0003] However, existing hook storage devices require high strength to withstand strong winds in the air, resulting in a large overall size and high design complexity. The existing hook storage devices also suffer from a highly unreasonable structural design, with a small load-bearing area and an unbalanced and unstable structure, making it difficult to support excessively heavy hooks. Furthermore, the bottom of existing hook storage devices is prone to water accumulation and rust, leading to hook corrosion and serious losses. Utility Model Content
[0004] The technical problem to be solved by this utility model is: how to make the force on the hook more balanced and stable during storage. In order to solve the above technical problem, this utility model provides a hook storage seat, including a first side plate, a second side plate, a third side plate and a fourth side plate disposed on the deck. The first side plate, the second side plate, the third side plate and the fourth side plate are sequentially enclosed to form a cavity for accommodating the hook.
[0005] The cavity is provided with a first bottom plate and a second bottom plate. The first bottom plate and the second bottom plate are arranged opposite to each other along the central axis of the first side plate. Both the first bottom plate and the second bottom plate are inclined. The first bottom plate and the second bottom plate are respectively used to abut and limit the hook claws on both sides of the hook.
[0006] The first side plate and the third side plate are respectively provided with through holes in the middle, and a locking pin is detachably provided in the through hole.
[0007] Preferably, a drainage groove is provided between the first base plate and the second base plate.
[0008] Preferably, the top of the first side plate is provided with a first folding part, the top of the third side plate is provided with a second folding part, the top of the second side plate is provided with a third folding part, and the top of the fourth side plate is provided with a fourth folding part. The first folding part, the second folding part, the third folding part, and the fourth folding part are all folded toward the side away from the cavity.
[0009] Preferably, the folding angles of the first folding portion, the second folding portion, the third folding portion, and the fourth folding portion are all thirty degrees.
[0010] Preferably, the distance between the top ends of the second folding portion and the fourth folding portion is less than the length of the first side plate.
[0011] Preferably, the distance between the second side plate and the hook, and the distance between the fourth side plate and the hook, are both no more than 10mm.
[0012] Preferably, the first end of the locking pin is provided with a pull ring, and the second end of the locking pin is provided with a tongue pin.
[0013] Preferably, the device further includes a shelf, which is disposed at the first end of the locking pin and fixedly connected to the first side plate or the third side plate. The shelf is provided with a shelf groove for accommodating the locking pin.
[0014] Preferably, the tongue-type pin is connected to a chain, and the other end of the chain is fixed to the third side plate or the first side plate.
[0015] Preferably, the first side plate, the second side plate, the third side plate, and the fourth side plate are all welded and fixed to the deck.
[0016] Compared with the prior art, the hook storage base provided in this embodiment of the present invention has the following advantages:
[0017] In this invention, an inclined first base plate and a second base plate are provided inside the cavity, and the first base plate and the second base plate respectively abut against the two claws of the limiting hook. Compared with the horizontally arranged base plate structure, the first base plate and the second base plate have a larger contact area and more contact points with the hook, and the forces applied by the two base plates to the hook are also opposite. Together with the locking pin, they form a triangular structure, which can better distribute and bear the weight of the hook, and the force on the hook is more balanced and stable. In addition, since the first base plate and the second base plate are arranged opposite each other, the included angle formed between them can also disperse and offset the lateral force caused by the longitudinal tilt of the ship to the greatest extent, avoid the rotation and swaying of the hook, and further improve the balance of the force and the stability of the hook during storage.

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0024] like Figures 1 to 4 As shown, a preferred embodiment of the present invention provides a hook storage seat, which includes a first side plate 1, a second side plate 2, a third side plate 3 and a fourth side plate 4 disposed on the deck. The first side plate 1, the second side plate 2, the third side plate 3 and the fourth side plate 4 are sequentially arranged to form a cavity for accommodating the hook 5.
[0025] The cavity is provided with a first bottom plate 6 and a second bottom plate 7. The first bottom plate 6 and the second bottom plate 7 are arranged opposite to each other along the central axis of the first side plate 1. The first bottom plate 6 and the second bottom plate 7 are both inclined. The first bottom plate 6 and the second bottom plate 7 are respectively used to abut the hook claws on both sides of the limiting hook 5.
[0026] The first side plate 1 and the third side plate 3 are respectively provided with through holes in the middle, and a locking pin 8 is detachably provided in the through hole.
[0027] Specifically, in traditional technical solutions, the base plate is a horizontal structure, and the contact point between the base plate and the hook 5 is in the middle of the base plate. This single contact point bears the entire weight of the hook 5, making the stress on the hook 5 highly unstable during storage and requiring higher strength from the base plate. However, in the actual use of this embodiment, the hook 5 is placed horizontally into the cavity. The first base plate 6 and the second base plate 7 inside the cavity abut against the hook claws on both sides of the hook 5. Both base plates simultaneously provide support for the hook 5, resulting in more contact points and a larger contact area. This allows for better weight distribution on the hook 5, leading to a better stress state during storage. Furthermore, the first base plate 6 and the second base plate 7, together with the locking pin 8, form a three-point support, and the forces applied between the first base plate 6 and the second base plate 7 are opposite, making the stress on the hook 5 more balanced and stable during storage. Furthermore, during the movement of the ship, the ship often tilts forward or backward, at which time the hook 5 will also be moved. The second bottom plate 7 and the second bottom plate 8 in this application are both inclined. When the ship tilts forward or backward, the first bottom plate 6 and the second bottom plate 7 can largely offset and disperse the tilting force brought by the ship, prevent the hook 5 from turning and swaying, and ensure the stability of the hook 5 during storage.
[0028] In some embodiments, a drainage channel 9 is provided between the first bottom plate 6 and the second bottom plate 7. Specifically, in this embodiment, the first bottom plate 6 and the second bottom plate 7 divide the cavity into an upper cavity and a lower cavity. The upper cavity is used to house the hook 5, while the lower cavity is used to suspend the hook 5, preventing it from directly contacting the deck. The first bottom plate 6 and the second bottom plate 7 are not directly connected; instead, a drainage channel 9 is provided between them. Water on the hook 5 can flow along the first bottom plate 6 and the second bottom plate 7 and drain into the lower cavity through the drainage channel 9, preventing water accumulation in the upper cavity and avoiding prolonged direct contact between accumulated water and the hook 5, thus preventing corrosion of the hook 5 caused by water accumulation. Furthermore, in some other embodiments, drainage holes can be provided on the four side plates to allow water in the lower cavity to drain to the outside deck, preventing water accumulation in the lower cavity. Even further, the deck in the lower cavity can be provided with an inclined structure to accelerate the drainage of accumulated water from the lower cavity to the outside deck.
[0029] In some embodiments, the top end of the first side plate 1 is provided with a first folding portion 11, the top end of the third side plate 3 is provided with a second folding portion 31, the top end of the second side plate 2 is provided with a third folding portion 21, and the top end of the fourth side plate 4 is provided with a fourth folding portion 41. The first folding portion 11, the second folding portion 31, the third folding portion 21, and the fourth folding portion 41 are all folded toward the side away from the cavity.
[0030] Furthermore, the folding angles of the first folding part 11, the second folding part 31, the third folding part 21, and the fourth folding part 41 are all thirty degrees.
[0031] Furthermore, the distance between the top ends of the second folding portion 31 and the fourth folding portion 41 is less than the length of the first side plate 1.
[0032] Specifically, each of the four side panels is provided with an outward folding section, which can increase the cross-sectional area of the storage opening, allowing the hook 5 to be placed into the cavity more accurately and conveniently. Once the hook 5 enters the enclosure area, it can slide smoothly into the cavity through the inclined ramp of the folding section. The 30-degree setting is the optimal angle option for this solution. Other tilt angles can also be selected in other embodiments. In addition, the tilt angle in this embodiment refers to the angle between the inclined surface of each folding section and the vertical line. Furthermore, the distance between the second folding part 31 and the fourth folding part 41 is limited so that the distance between the second side plate 2 and the fourth side plate 4 is less than the length of the first side plate 1, and the height of the second folding part 31 and the fourth folding part 41 is less than the height of the first folding part 11 and the third folding part 21. This allows the hook 5 line to be guided and limited by the first folding part 11 and the second folding part 31, and then by the second folding part 31 and the fourth folding part 41. The guidance of the hook 5 is carried out in segments, so that the hook 5 can be guided into the cavity better, more conveniently and stably.
[0033] In some embodiments, the distance between the second side plate 2 and the hook 5, and the distance between the fourth side plate 4 and the hook 5, are both no greater than 10mm. Specifically, there are gaps between the second side plate 2 and the fourth side plate 4 and the installed hook 5. These gaps allow the hook 5 to have a certain amount of room to move within the cavity, enabling the hook 5 to be easily and stably stored in the cavity without getting stuck. Limiting this distance to less than 10mm is to avoid the problem of the hook 5 being unstable in position within the cavity due to excessively large gaps, making it difficult for the locking pin 8 to pass through the hole on the hook 5 to position it.
[0034] In some embodiments, the first end of the locking pin 8 is provided with a pull ring 81, and the second end of the locking pin 8 is provided with a tongue-type pin 82.
[0035] Furthermore, it also includes a shelf 83, which is disposed at the first end of the locking pin 8 and is fixedly connected to the first side plate 1 or the third side plate 3. The shelf 83 is provided with a shelf groove for accommodating the locking pin 8.
[0036] Furthermore, a chain 84 is connected to a tongue-type pin 82, and the other end of the chain 84 is fixed to the third side plate 3 or the first side plate 1.
[0037] Specifically, the pull ring 81 allows workers to easily pull out and insert the locking pin 8 from the through hole, facilitating the fixing and loosening of the hook 5 and improving work efficiency. Once the locking pin 8 is inserted from one end of the device to the other, a tongue-tipped pin 82 can be inserted into the end of the locking pin 8 to secure it and fix the hook 5. To loosen the hook 5, the tongue-tipped pin 82 must be pulled out first, and then the locking pin 8 can be dragged out. The shelf 83 facilitates the removal of the locking pin 8 and also provides storage space for it, improving work efficiency and preventing loss. The chain 84 prevents the tongue-tipped pin 82 from being lost.
[0038] In addition, in some other embodiments, the tongue-type pin 82 can be fixed on the locking pin 8, and a through groove is provided in the through hole corresponding to the tongue-type pin 82. The locking pin 8 can be limited and fixed by rotating it.
[0039] In some embodiments, the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4 are all welded and fixed to the deck. Welding and fixing make the structural strength of the first side plate 1, the second side plate 2, the third side plate 3, and the fourth side plate 4 more stable and reliable, and less prone to problems such as loosening.
[0040] In summary, this embodiment of the invention provides a hook 5 storage base, which provides multiple support points for the hook 5, offering a more stable support effect. Furthermore, it can counteract and disperse the tilting force caused by the ship when it heels or rolls, preventing the hook 5 from swaying and making it more balanced and stable. In addition, the drainage channel 9 prevents water accumulation inside the storage base, avoiding prolonged contact with seawater and subsequent rusting of the hook 5.
[0041] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
