Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a hook-and-unhook device. Background Technology

[0002] With technological advancements and increasingly complex engineering needs, hoisting techniques for large equipment are constantly evolving. Currently, hoisting technology has developed from traditional, simple hoisting into a comprehensive technology incorporating high-tech methods such as computer simulation and intelligent monitoring.

[0003] The containment structure of the AP series nuclear power plant is modular. These modules include a bottom head, a top head, and several sections of the shell. Each module is finally assembled through hoisting and welding. Each module is generally hoisted directly using a multi-sling system. A wireless static stress monitoring system is introduced for monitoring, adjustment, and early warning, so that the stress of each sling can be visualized and digitally presented in real time, ensuring the hoisting quality and safety of the modules.

[0004] Taking the bottom end cap as an example, multiple lifting lugs are installed on the bottom end cap. During the hoisting process, truck cranes and tower cranes are required to assist in connecting or removing the multiple slings to the multiple lifting lugs one by one. The above method of connecting and removing slings and lifting lugs results in a long construction time and high construction cost.

[0005] Therefore, this application provides a new hook-and-unhook device to address the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a hook-and-unhook device to at least alleviate the technical problem in the prior art that the disassembly and assembly of slings and lugs during the hoisting of various modules of the containment structure results in long hoisting time and high construction costs.

[0007] To achieve the above objectives, this utility model provides a hook-and-unhook device, which is used to hook and unhook slings to lifting lugs on the containment module during the hoisting of the containment module. The containment module has multiple lifting lugs, and the slings are hoisted at the middle of the containment module.

[0008] The hook-and-unhook device includes a hook-and-unhook assembly, which includes a winch assembly. The winch assembly is used to engage with the safety housing module and is located above the lifting lug. The winch assembly releases the winch rope until it can connect with the sling. At this time, the winch assembly tightens the winch rope so that the winch rope can drive the sling to move to the lifting lug.

[0009] The number of hook-unhooking devices is the same as the number of lifting lugs, and each hook-unhooking device corresponds to one lifting lug.

[0010] Furthermore, the winch assembly includes a winch machine, a power supply unit for supplying power to the winch machine, and a connecting frame for connecting the winch machine to the power supply unit, wherein the connecting frame can be snapped into the containment module.

[0011] Furthermore, the connecting frame includes a connecting plate, a first frame for fixing the winch, and a second frame for fixing the power supply component. The first frame and the second frame are connected through the connecting plate, and the connecting plate is provided with a slot for engaging with the containment module.

[0012] Furthermore, multiple connecting plates are provided, and the multiple connecting plates are spaced apart between the first frame and the second frame.

[0013] Furthermore, the number of connecting plates is two.

[0014] Furthermore, the first frame includes multiple first carbon steel plates, which are welded together by first angle steel to form the first frame; the second frame includes multiple second carbon steel plates, which are welded together by second angle steel to form the second frame; the connecting plate is a carbon steel plate.

[0015] Furthermore, the width of the slot ranges from 46mm to 50mm, and the depth ranges from 146mm to 150mm.

[0016] Furthermore, the hook-and-unhook device also includes a fixed pulley disposed on the containment module, the fixed pulley being disposed between the winch assembly and the lifting lug.

[0017] Furthermore, the hook-and-unhook device also includes a remote control for controlling the winch assembly.

[0018] Furthermore, the containment module is provided with sixteen lifting lugs.

[0019] By adopting the above technical solution, the hook-and-unhook device of this utility model has at least the following beneficial effects:

[0020] During the hoisting of the containment module, the winch assembly is first engaged with the containment module, positioning it above the lifting lug. The winch assembly then releases the winch rope until it reaches the sling and connects with it. When it is necessary to hook the sling to the lifting lug, the winch assembly tightens the winch rope, causing it to pull the sling closer to the lifting lug until it reaches it. The sling is then connected to the lifting lug. When it is necessary to detach the sling from the lifting lug, the sling is first disconnected from the lifting lug. Then, the winch assembly releases the winch rope, preventing it from pulling the sling further. The sling then returns to its original position under its own weight, thus detaching the sling from the lifting lug.

[0021] In this embodiment, the number of hook-and-unhook devices is the same as the number of lifting lugs, and multiple hook-and-unhook devices correspond one-to-one with multiple lifting lugs. Thus, multiple hook-and-unhook devices can simultaneously perform hook-and-unhook operations on multiple lifting lugs. This setup can shorten the hoisting time of the containment module, significantly improve construction efficiency, and reduce construction costs. On the other hand, multiple hook-and-unhook devices simultaneously pull multiple slings one-to-one to the lifting lugs for hook-and-unhook operations, ensuring that each sling experiences consistent force during the process of being pulled to the lifting lug. That is, each sling has consistent tension when connected to the lifting lug, which significantly improves the hoisting stability of the containment module. Attached Figure Description

[0036] Example 1

[0037] Please see Figure 1 and combined Figure 3 This embodiment provides a hook-and-unhook device, which is used to hook and unhook the sling 2 to the lifting lugs 3 on the containment module 1 during hoisting. Multiple lifting lugs 3 are provided on the containment module 1, and the sling 2 is hoisted in the middle of the containment module 1. The hook-and-unhook device includes a hook-and-unhook assembly 4, which includes a winch assembly 41. The winch assembly 41 is used to engage with the containment module 1 and is located above the lifting lugs 3. The winch assembly 41 releases the winch rope 412 until it can connect with the sling 2. At this time, the winch assembly 41 tightens the winch rope 412, enabling the winch rope 412 to move the sling 2 to the lifting lug 3. The number of hook-and-unhook devices 4 is the same as the number of lifting lugs 3, and multiple hook-and-unhook devices 4 correspond one-to-one with multiple lifting lugs 3.

[0038] It should be noted that the hook-and-unhook device in this embodiment can be used to hook and unhook the sling 2 and the lifting lug 3 on the containment module 1 during the hoisting of the containment module 1. The containment module 1 can be a bottom end cap, a top end cap, or a cylinder between the two. The bottom end cap is used as an example in the figure for illustration.

[0039] For this setting, please refer to [link / reference]. Figure 3 During the hoisting of containment module 1, first, the winch assembly 41 is engaged with containment module 1, positioning the winch assembly 41 above the lifting lug 3. Then, the winch assembly 41 releases the winch rope 412 until it reaches the sling 2 and connects with it. Please refer to [link to relevant documentation]. Figure 4 and Figure 5 When it is necessary to connect the sling 2 to the lifting lug 3, the winch assembly 41 tightens the winch rope 412, causing the winch rope 412 to move the sling 2, so that the sling 2 gradually approaches the lifting lug 3 until the sling 2 moves to the lifting lug 3, and then the sling 2 is connected to the lifting lug 3. When it is necessary to disconnect the sling 2 from the lifting lug 3, the sling 2 is first disconnected from the lifting lug 3, and then the winch assembly 41 releases the winch rope 412, so that the winch rope 412 can no longer pull the sling 2, so that the sling 2 returns to its original position under its own weight, thus realizing the disconnection of the sling 2 from the lifting lug 3.

[0040] In this embodiment, the number of hook-and-unhook devices 4 is the same as the number of lifting lugs 3, and multiple hook-and-unhook devices 4 correspond one-to-one with multiple lifting lugs 3. Thus, multiple hook-and-unhook devices 4 can simultaneously perform hook-and-unhook operations on multiple lifting lugs 3 for slings 2. This setup can shorten the hoisting time of the containment module 1, greatly improve construction efficiency, and reduce construction costs. On the other hand, multiple hook-and-unhook devices 4 simultaneously pull multiple slings 2 one-to-one to the lifting lugs 3 for hook-and-unhook operations, so that each sling 2 is subjected to consistent force during the process of being pulled to the lifting lug 3, that is, the tension of each sling 2 is consistent when connected to the lifting lug 3, which significantly improves the hoisting stability of the containment module 1.

[0041] Preferably, please refer to Figure 2 In this embodiment, the winch assembly 41 includes a winch machine 411, a power supply unit (not shown in the figure) for supplying power to the winch machine 411, and a connecting frame for connecting the winch machine 411 to the power supply unit, and the connecting frame can be snapped into the containment module 1.

[0042] Among them, the winch 411 is the prior art, which can release and tighten the winch 412. The power supply unit is used to supply power to the winch 411. The connecting frame is used to connect the winch 411 to the power supply unit, so that the power supply unit can stably supply power to the winch 411. The connecting frame can also be snapped into the containment module 1, realizing that the winch assembly 41 is snapped into the containment module 1.

[0043] Preferably, please refer to Figure 2 In this embodiment, the connecting frame includes a connecting plate 413, a first frame 415 for fixing the winch 411, and a second frame 416 for fixing the power supply component. The first frame 415 and the second frame 416 are connected by the connecting plate 413. The connecting plate 413 is provided with a slot 414 for engaging with the containment module 1.

[0044] This setup fixes the winch 411 to the first frame 415 and the power supply unit to the second frame 416. The first frame 415 and the second frame 416 are connected by the connecting plate 413, thus achieving relative fixation between the winch 411 and the power supply unit.

[0045] The winch assembly 41 is connected to the containment module 1 via the slot 414.

[0046] Preferably, please refer to Figure 2 In this embodiment, multiple connecting plates 413 are provided, and the multiple connecting plates 413 are spaced apart between the first frame 415 and the second frame 416. For example, the number of connecting plates 413 is two, three, four, etc. The arrangement of multiple connecting plates 413 makes the fixing of the winch 411 and the power supply component more reliable and secure.

[0047] Preferably, in this embodiment, there are two connecting plates 413. This arrangement enhances the reliability of the fixation between the winch 411 and the power supply unit, and also reduces the cost of the equipment.

[0048] Preferably, in this embodiment, the first frame 415 includes a plurality of first carbon steel plates, which are welded together by first angle steel to form the first frame 415; the second frame 416 includes a plurality of second carbon steel plates, which are welded together by second angle steel to form the second frame; the connecting plate 413 is a carbon steel plate.

[0049] This design improves the structural strength of the connecting frame and ensures a secure fixation between the winch 411 and the power supply components.

[0050] Preferably, in this embodiment, the width of the card slot 414 ranges from 46mm to 50mm, and the depth ranges from 146mm to 150mm. For example, the width of the card slot 414 is 46mm, 47mm, 48mm, 49mm, or 50mm, and the depth of the card slot 414 is 146mm, 147mm, 148mm, 149mm, or 150mm, etc.

[0051] This configuration allows the slot 414 to match the bottom end cap, top end cap, and cylinder, so that the connecting plate 413 can be snapped into the bottom end cap, top end cap, and cylinder. Therefore, the hook-and-unhook device of this embodiment is suitable for hoisting the bottom end cap, top end cap, and cylinder, and has a wider range of applications.

[0052] Preferably, please refer to Figure 1 In this embodiment, the hook-and-unhook device 4 also includes a fixed pulley 42 disposed on the safety housing module 1, and the fixed pulley 42 is disposed between the winch assembly 41 and the lifting lug 3.

[0053] With this setup, when hoisting the containment module 1, the winch assembly 41 is first snapped onto the containment module 1, so that the winch assembly 41 is positioned above the lifting lug 3. The fixed pulley 42 is positioned between the winch assembly 41 and the lifting lug 3. The winch mechanism 411 of the winch assembly 41 releases the winch rope 412, which is then passed around the fixed pulley 42. After the fixed pulley 42 reverses the direction of the winch rope 412, the winch rope 412 is released to reach the sling 2 and connected to it. When it is necessary to connect sling 2 to lug 3, the winch 411 of the winch assembly 41 tightens the rope 412, which in turn moves sling 2 closer to lug 3 until it reaches lug 3. Then, sling 2 is connected to lug 3. When it is necessary to disconnect sling 2 from lug 3, sling 2 is first disconnected from lug 3. Then, the winch 411 of the winch assembly 41 releases the rope 412, preventing the rope 412 from pulling sling 2. As a result, sling 2 returns to its original position under its own weight, thus disconnecting sling 2 from lug 3.

[0054] Preferably, in this embodiment, the hook-and-unhook device 4 further includes a remote control for controlling the winch assembly 41. This configuration enables remote control of the winch assembly 41, improving the safety and convenience of construction.

[0055] Preferably, please refer to Figure 1 In this embodiment, the containment module 1 has sixteen lifting lugs 3.

[0056] In other words, the hook-and-unhook device 4 is equipped with sixteen sets. With this setup, when hoisting the containment module 1, sixteen remote controllers control sixteen winches 411 to simultaneously perform hook-and-unhook operations. The purpose is to efficiently and safely complete the hoisting construction of the AP stack-type large containment module 1, reduce the operating costs and risks when connecting and dismantling the slings 2, and improve operating efficiency and quality.

[0057] In summary, the hook-and-unhook device of this embodiment uses sixteen sets of hook-and-unhook devices 4 to perform hook-and-unhook operations simultaneously, ensuring that each sling 2 is subjected to consistent force during the process of being pulled to the lifting lug 3. That is, each sling 2 has the same tension when connected, preventing the center of gravity of the module from shifting during hoisting. Furthermore, the simultaneous traction and connection of the sixteen sets of hook-and-unhook devices 4 to the sling 2, instead of rotating the traction and requiring repeated use of the winch, further reduces the time and labor costs of the operation and construction.

[0058] The preparation work for using the hook-and-unhook device of this embodiment is as follows: Sixteen sets of hook-and-unhook devices 4 are used to pull and unhook the sling 2. The performance, working characteristics, and operating environment of the winch 411 are studied through multiple tests until a winch 411 that meets the performance requirements of the site is selected. At the same time, the winch 411 and its connecting frame are subjected to strict load tests, and the connecting frame of the winch 411 is subjected to mechanical analysis to ensure the quality of the connecting frame. This ensures the safety and quality of the on-site construction and makes it feasible to use the sixteen sets of hook-and-unhook devices 4 to complete this work.

[0059] In summary, the hook-and-unhook device of this embodiment is easy to install and operate, shortens operation time, improves construction efficiency, and reduces construction risks. Furthermore, the device is reusable, saving costs and making it widely applicable. Compared to the previous use of truck cranes and tower cranes to assist in the connection and dismantling of slings 2, this technological innovation has improved lifting quality, shortened the construction cycle, and created the necessary conditions for the installation of the containment module 1, achieving significant economic and social benefits.
