Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] The following reference Figures 1 to 4 The lifting fixture described in some embodiments of this application is described.

[0033] See Figures 1 to 4 As shown, an embodiment of this application provides a lifting fixture, including: a first support member 3, a fixing member 2, a fixed pulley, a movable pulley assembly 5, and a lifting rope; wherein, the first support member 3 is detachably mounted on the hull via the fixing member 2; the movable pulley assembly 5 includes a second support member 51 and a movable pulley 52 and a hanging member 53 connected to the second support member 51; wherein, the number of movable pulleys 52 is at least two, and they are parallel to each other and sequentially arranged along a first preset direction, and any movable pulley 52 can rotate relative to the second support member 51; the hanging member 53 is used to suspend heavy objects such as pipes via ropes;

[0035] Based on the structure described above, the lifting fixture provided in this application is used as follows: First, the first support member 3 is fixed to the hull by the fixing member 2. Then, the fixed pulley is installed on the first support member 3 so that the wheel of the fixed pulley can rotate freely. Then, one end of the lifting rope is also fixed to the hull. Then, the lifting rope is wound around the wheel of the movable pulley 52 in the movable pulley assembly 5 and the wheel of the aforementioned fixed pulley in turn. The other end of the lifting rope wound around the fixed pulley is held by a person or by mechanical equipment. Then, the heavy object, such as a pipe, is hung on the lifting member 53. Then, the heavy object, such as the pipe, is lifted to the designated position, such as the deck, by a person or mechanical equipment. Of course, the lifting steps are not limited to the above and can be adjusted according to actual needs. In addition, it should be noted that, preferably, the number of movable pulleys 52, fixed pulleys and lifting ropes are equal and correspond one-to-one to form multiple sets of pulley structures. One set of pulley structures can be selected for use, or all of them can be used simultaneously, depending on actual needs.

[0036] It is evident that the use of pulley blocks effectively improves on-site production efficiency, saves working hours, reduces costs, conserves company crane resources, and reduces personnel safety hazards. This tooling can also be applied to other hoisting processes, similarly improving production efficiency and ensuring the project is completed smoothly according to schedule.

[0037] Furthermore, preferably, there are two movable pulleys 52, correspondingly equipped with two fixed pulleys and two suspension ropes, forming two sets of pulley structures. Depending on the weight of the object being dropped, one pulley structure can be used, or all pulley structures can be used simultaneously, thus enhancing practicality. Of course, the number of pulley structures is not limited to the aforementioned two sets; it can also be more than two sets, such as three, four, or five sets, etc., depending on actual needs.

[0038] Furthermore, preferably, the lifting fixture also includes an auxiliary hanging component 4, and the auxiliary hanging component 4 is disposed on the first support component 3; the fixed pulley is detachably suspended on the auxiliary hanging component 4, and preferably, the auxiliary hanging component 4 is a hook, on which the hook of the fixed pulley can be suspended, and the structure is simple and the cost is low. Of course, it is not limited to this. In addition, it should be noted that: the auxiliary hanging component 4 may not be provided, and the fixed pulley may be directly installed on the first support component 3 by bolts, etc.

[0039] Furthermore, preferably, the first support member 3 is detachably mounted on the column 1 of the hull via the fixing member 2. Of course, it is not limited to this, and the installation position of the first support member 3 can be selected according to actual needs.

[0040] Furthermore, preferably, the fixing component 2 includes a first clamp and a second clamp, and the first clamp is installed on the column 1 of the hull, the second clamp is detachably connected to the first clamp, and the first support component 3 is installed inside the second clamp. The aforementioned clamps are more convenient to use and easier to disassemble later. Preferably, the first clamp and the second clamp can be connected by bolts, clips or welding.

[0041] It should be noted that the lifting fixtures provided in this application are not limited to cruise ship construction, but can also be applied to the construction of other types of ships, depending on actual needs.

[0042] In this embodiment, preferably, as follows: Figure 2 and Figure 3 As shown, the second support member 51 includes a support plate 511, a partition plate 512, and a connecting member 513; wherein, there are two support plates 511, which are spaced apart along a first preset direction, and there is at least one partition plate 512, which is disposed between the two support plates 511 to divide the two support plates 511 into at least two mounting cavities, and a movable pulley 52 is installed in each mounting cavity; the two support plates 511 and the partition plate 512 are connected by the connecting member 513.

[0043] As can be seen from the structure described above, the two support plates 511 and the middle partition plate 512 are connected as one unit by the connecting member 513, and the two support plates 511 and the middle partition plate 512 enclose a space for installing the movable pulley 52, which can rotate freely in the corresponding installation cavity.

[0044] Furthermore, preferably, the two support plates 511 and the partition plate 512 have the same structure, which facilitates assembly. Of course, it is not limited to this, and the above-mentioned components can also adopt different structures, depending on the actual needs.

[0045] In this embodiment, preferably, as follows: Figure 2 and Figure 3 As shown, all the movable pulleys 52 are rotatably connected to the two support plates 511 and the partition plate 512 through the same rotating shaft.

[0046] As can be seen from the structure described above, all the movable pulleys 52 are rotatably connected to the support plate 511 and the partition plate 512 through the same rotating shaft, which ensures consistency during the rotation process, reduces the space occupied, reduces the input of parts, and lowers the cost. Of course, it is not limited to this, and different rotating shafts can also be equipped, depending on the actual needs.

[0047] In this embodiment, preferably, as follows: Figure 2 As shown, both support plates 511 and partition plate 512 are formed with mounting through holes, and are respectively fitted onto the connecting member 513 through the mounting through holes.

[0048] As can be seen from the structure described above, the two support plates 511 and the partition plate 512 are all fitted onto the connecting member 513, so that the four can be connected together to form a whole, and the overall structure is stable.

[0049] In this embodiment, preferably, as follows: Figure 2 As shown, the connecting member 513 is a screw, and the second support member 51 also includes a nut 514 installed on the screw. Nuts 514 are provided on the opposite sides of the two support plates 511, and the nuts 514 are used to limit the position of the support plates 511.

[0050] As described above, the two nuts 514 are respectively installed on the outer sides of the two support plates 511, which serve to limit the outer side of the support plates 511. In conjunction with the limiting structure of the hook or lifting ring described below, they also limit the support plates 511, so that a certain distance can be maintained between the two support plates 511. This provides a certain space for the rotation of the movable pulley 52, avoiding jamming and preventing the two support plates 511 from detaching from the connecting member 513. This makes the overall structure safer and more reliable. Moreover, the use of a screw as the connecting member 513, which has threads, makes it difficult for the support plates 511 to move on it during hoisting. Of course, it is not limited to this. The connecting member 513 can also be a regular rod without threads with effective limiting blocks at both ends, depending on the actual needs.

[0051] In this embodiment, preferably, as follows: Figure 2 As shown, the hanging component 53 is a lifting ring, which can be used in conjunction with ropes to suspend heavy objects such as pipes. The operation is simple and convenient. When the hanging component 53 is a lifting ring, preferably, through holes are formed on both opposite sides of the lifting ring, and the ring is fitted onto the connecting component 513 through the through holes. The structure of the lifting ring with the through holes is located between the two support plates 511. This part can limit the two support plates, so that a certain distance can be maintained between the two support plates 511, thereby providing a certain space for the rotation of the movable pulley 52 and avoiding jamming.

[0052] Of course, the structure of the hanging component 53 is not limited to the above; it can also be a hook or other structure, such as... Figure 4 As shown, and preferably, the lifting fixture also includes a connecting plate 54, with mounting protrusions formed on both opposite sides of the hook, and each mounting protrusion is equipped with a connecting plate 54, and the two are connected; both connecting plates 54 are sleeved on the connecting member 513 and located between the two support plates 511.

[0053] As can be seen from the structure described above, hooks can be used to suspend heavy objects such as pipes, and both connecting plates 54 can limit the two support plates 511, so that the two support plates 511 can maintain a certain distance, thereby providing a certain space for the rotation of the movable pulley 52 and avoiding jamming.

[0054] It should be noted that the structure is not limited to the above-mentioned structure that uses hooks or rings to limit the two support plates 511. Other structures can also be used. For example, when the following structure is used, there is no need to set up a limiting structure. Preferably, the two support plates 511 and the partition plate 512 are all connected to the connecting member 513 by welding. In this case, the positions of the two support plates 511 and the partition plate 512 will not change, thus ensuring that the movable pulley 52 always has a certain rotational clearance, and thus preventing jamming and other problems.

[0055] In this embodiment, preferably, as follows: Figure 2 As shown, the second support member 51 also includes a reinforcing member 55 and a connecting ring 56; wherein, the reinforcing member 55 is installed between the two support plates 511, and both ends of the reinforcing member 55 are respectively connected to the two support plates 511; the connecting ring 56 is connected to the reinforcing member 55.

[0056] As can be seen from the structure described above, the reinforcing component 55 serves to support and reinforce the two support plates 511, making the overall structure more robust and stable. In addition, anti-sway ropes can be installed using the connecting ring 56, which can be pulled by the workers on the lower deck to prevent swaying during hoisting and also effectively avoid expansion with other structures on the hull.

[0057] Furthermore, preferably, the reinforcing member 55 can be a bolt with a nut installed on it, and the nut is located on the outside of the support plate 511. Of course, it is not limited to this. The reinforcing member 55 can also be a rod without threads, etc., depending on the actual needs.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
