Description

Technical Field

[0001] This application relates to the technical field of shipbuilding, and particularly to a lug cutting wire saw machine. Background Art

[0002] In the manufacturing process of large ships, the hull structure needs to be divided into multiple modules, and each module is equipped with multiple lugs for hoisting operations. After these modules are combined into a complete hull, a large number of lugs must be removed (the removed lugs can be recycled). After the lug body is removed, there are often protruding roots left in the welding area at its bottom, and these parts protruding above the hull plane also need to be completely removed to ensure the cleanliness and aesthetics of the hull surface, which is a commonly adopted process in the international shipbuilding industry. For the removal of the remaining parts of the lugs, the current technology mainly relies on manual grinding and carbon explosion methods. However, this method has the disadvantages of large man-hour consumption, low efficiency, high cost, high labor intensity, and problems of noise and dust pollution. Summary of the Invention

[0003] The purpose of this application is to provide a lug cutting wire saw machine to overcome or alleviate the above technical problems in the prior art.

[0004] To achieve the above purpose, this application provides the following technical solutions:

[0005] A lug cutting wire saw machine, which includes: a frame, a cutting drive mechanism, a driving wheel set, a first guide wheel set, a second guide wheel set, a third guide wheel set, and a cutting wire. The number of the first guide wheel set, the second guide wheel set, and the third guide wheel set is at least two. The cutting drive mechanism is assembled on the frame, and the driving wheel set is connected to the cutting drive mechanism to rotate under the drive of the cutting drive wheel set. The first guide wheel set is installed on the frame in a first split side manner and assembled on the left and right sides of the driving wheel set. The second guide wheel set is installed on the frame in a second split side manner and assembled on the left and right sides of the driving wheel set. The third guide wheel set is installed on the frame in a third split side manner and assembled on the left and right sides of the driving wheel set. The cutting wire is wound and tensioned in a closed manner on the driving wheel set, the first guide wheel set, the second guide wheel set, and the third guide wheel set.

[0006] As pointed out in the background art, after the module combination in large ship manufacturing is completed, a large number of lugs need to be removed and their remaining roots need to be removed. The existing manual grinding and carbon explosion methods have problems such as large man-hour consumption, low efficiency, high cost, high labor intensity, and noise and dust pollution. The lug cutting wire saw machine of this application solves these problems in the following ways:

[0007] 1. Improve efficiency and reduce man-hour consumption:

[0008] In this solution, the design of multiple guide wheel groups (the first, second, and third guide wheel groups) in cooperation with the driving wheel group and the cutting rope forms a stable and efficient cutting structure. The cutting drive mechanism drives the driving wheel group to rotate, and the driving wheel group in turn drives the cutting rope wound around it to rotate at high speed. Since the number of the first, second, and third guide wheel groups is at least two and they are distributed on both the left and right sides of the driving wheel group, they can guide the cutting rope to form a specific movement trajectory for efficient cutting of the lugs. Compared with manual grinding, the automated cutting process of the machine can be carried out continuously and quickly, greatly shortening the cutting time for each lug, thus significantly improving the overall cutting efficiency and reducing the man-hours required to complete the cutting of a large number of lugs.

[0009] For example, manual grinding may require workers to operate on the root of each lug carefully one by one, which is slow and prone to fatigue. While this rope saw machine can cut multiple lugs in batches at one time, or complete the cutting of more lugs per unit time, greatly improving the work efficiency and reducing the man-hours.

[0010] 2. Cost reduction:

[0011] On the one hand, improving efficiency means that more work tasks can be completed in the same time, reducing the input of labor costs. The lug cutting work that originally required a large number of workers to work for a long time can now be carried out with the help of the rope saw machine, and only a small number of operators are needed to monitor and maintain the equipment, reducing the labor costs.

[0012] On the other hand, the first guide wheel group, the second guide wheel group, and the third guide wheel group make the cutting rope form a closed loop and increase the length of the cutting rope, avoiding frequent replacement caused by too short cutting rope and reducing the consumable cost. As a vulnerable part, frequent replacement of the cutting rope not only increases the material cost, but also wastes time due to downtime for replacement, affecting the work efficiency. This solution extends the service life of the cutting rope through reasonable structural design, reducing the comprehensive cost.

[0013] 3. Reduction of labor intensity:

[0014] Traditional manual grinding and carbon explosion method require workers to hold tools for high-intensity operations, with extremely high labor intensity. While this lug cutting rope saw machine adopts an automated cutting method, and workers only need to operate the equipment and monitor the cutting process without performing heavy physical labor. The main work of workers has changed to relatively easy tasks such as starting, stopping, adjusting parameters of the equipment and regular maintenance, greatly reducing the labor intensity.

[0015] 4. Reduction of noise and dust pollution:

[0016] Manual grinding generates sharp and ear-piercing frictional noises, and the carbon explosion method causes intense sounds during operation. When the cutting drive mechanism of this wire saw machine drives the driving wheel set and the cutting wire to operate, its working noise is relatively small. The cutting wire runs smoothly under the guidance of the guide wheel set, and the cutting process with the lifting lug is relatively gentle and does not produce high-decibel noises like traditional methods.

[0017] At the same time, manual grinding and the carbon explosion method generate a large amount of dust, which is harmful to the working environment and the health of workers. During the cutting process of the wire saw machine, due to the characteristics of the cutting method, there is no phenomenon of a large amount of dust flying, effectively reducing dust pollution, improving the working environment, and ensuring the physical health of workers.

For example, it can be a fixed connection or a connection; it can be directly connected or indirectly connected through an intermediate component. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0029] See Figures 1-8 As shown, an embodiment of the present application provides a lifting lug cutting wire saw machine, which includes: a frame 1, a cutting drive mechanism 2, a driving wheel set 3, a first guide wheel set 4, a second guide wheel set 5, a third guide wheel set 6, and a cutting wire 7. The number of the first guide wheel set 4, the second guide wheel set 5, and the third guide wheel set 6 is at least two. The cutting drive mechanism 2 is assembled on the frame 1. The driving wheel set 3 is connected to the cutting drive mechanism 2 to rotate under the drive of the cutting drive mechanism 2. The first guide wheel set 4 is installed on the frame 1 in a first split side manner and assembled on the left and right sides of the driving wheel set 3. The second guide wheel set 5 is installed on the frame 1 in a second split side manner and assembled on the left and right sides of the driving wheel set 3. The third guide wheel set 6 is installed on the frame 1 in a third split side manner and assembled on the left and right sides of the driving wheel set 3. The cutting wire 7 is wound and tensioned around the driving wheel set 3, the first guide wheel set 4, the second guide wheel set 5, and the third guide wheel set 6 in a closed manner.

[0030] The specific number of the first guide wheel set 4, the second guide wheel set 5, and the third guide wheel set 6 is not uniquely limited.

[0031] By using the first guide wheel set 4, the second guide wheel set 5, and the third guide wheel set 6, the cutting rope 7 forms a closed loop. Moreover, by this means, the length of the cutting rope 7 is increased, thus avoiding the situation of frequent replacement caused by the too short cutting rope 7 and reducing the operation cost.

[0032] Preferably, in a specific embodiment, the above technical solution of this lifting lug cutting wire saw machine brings many significant benefits:

[0033] 1. Reduce operation cost

[0034] Reduce the cost of consumable replacement: By arranging multiple first guide wheel sets 4, second guide wheel sets 5, and third guide wheel sets 6, the cutting rope 7 forms a closed-loop structure, greatly increasing the actual effective working length of the cutting rope 7. In traditional cutting equipment, if the cutting rope is short, during frequent use, once the wear of the cutting rope reaches a certain degree, it needs to be replaced in time, otherwise it will affect the cutting effect and even lead to cutting failure. Replacing the cutting rope not only requires purchasing a new cutting rope, increasing the material cost, but also may delay the production progress due to downtime for replacement, generating additional time costs. In this solution, due to the increase in the length of the cutting rope, its service life is greatly extended, the replacement frequency of the cutting rope is reduced, and the cost input in terms of consumables is directly reduced.

[0035] Improve the equipment utilization efficiency: The cutting rope does not need to be replaced frequently, which means that the equipment can maintain continuous and stable operation for a longer time. During shipbuilding, a large number of lifting lugs need to be cut. If the equipment frequently stops due to replacing the cutting rope, the efficiency of the entire production process will be seriously affected. This wire saw machine reduces the downtime, enabling more lifting lugs to be cut per unit time, improving the equipment utilization efficiency, and from the perspective of the overall production process, reducing the comprehensive operation cost.

[0036] 2. Enhance the stability and reliability of the equipment

[0037] Stabilize the operation of the cutting rope: Multiple guide wheel sets work together to support and guide the cutting rope 7 from different directions, enabling the cutting rope to maintain a stable tension state and an accurate movement trajectory during operation. The first guide wheel set 4, the second guide wheel set 5, and the third guide wheel set 6 are respectively installed on the frame 1 in a specific side-by-side manner and are located on the left and right sides of the driving wheel set 3. They work together, just like building a solid track, allowing the cutting rope 7 to smoothly loop and run in it. This stability avoids problems such as shaking and deviation of the cutting rope during high-speed operation, ensures the accuracy and continuity of the cutting operation, and improves the reliability of the equipment operation.

[0038] Dispersed cutting force: When cutting the lifting lug, the cutting rope 7 will bear a large cutting force. The presence of multiple guide wheel groups enables the cutting force to be evenly dispersed to each guide wheel. Compared with the situation where a single or a few guide wheels support the cutting rope, the structural design in this solution can better bear and disperse the cutting force, reduce the pressure borne by each guide wheel, reduce the risk of damage to the guide wheel due to excessive force, further improve the stability and reliability of the equipment, and extend the overall service life of the equipment.

[0039] 3. Improve the flexibility of cutting operations

[0040] Adapt to different cutting requirements: The specific quantities of the first guide wheel group 4, the second guide wheel group 5, and the third guide wheel group 6 are not uniquely limited, which provides great flexibility for the equipment in practical applications. According to factors such as the size, shape, material, and distribution position of the lifting lugs in different shipbuilding scenarios, the quantities and layouts of the guide wheel groups can be flexibly adjusted. For example, in some areas with complex structures and dense distribution of lifting lugs, the quantity of the guide wheel groups can be appropriately increased to better guide the cutting rope 7 to reach specific positions for cutting; for conventional lifting lug cutting tasks, a more streamlined configuration of the guide wheel groups can be adopted to meet diverse cutting operation requirements.

[0041] Facilitate the adjustment of cutting parameters: Since the cutting rope 7 forms a closed loop and its length can be adjusted according to the settings of the guide wheel groups, during the actual cutting process, different cutting conditions can be adapted by changing parameters such as the tension and running speed of the cutting rope. For example, for harder lifting lug materials, the tension of the cutting rope can be appropriately increased to improve the cutting efficiency and quality; for some operations with high requirements for cutting accuracy, the running speed of the cutting rope can be reduced to ensure the cutting accuracy. This flexibility in adapting different cutting requirements by adjusting the relevant parameters of the cutting rope further expands the application range of the lifting lug cutting wire saw machine.

[0042] Optionally, the first guide wheel group 4, the second guide wheel group 5, and the third guide wheel group 6 are all assembled on the left and right sides of the driving wheel group 3 in a mirror-symmetrical manner. Here, the mirror symmetry is, for example, left-right mirror symmetry. The specific assembly implementation method can be set according to the application scenario and is not specifically limited.

[0043] In the specific application scenario of shipbuilding, it is not easy to achieve efficient and precise cutting of lifting lugs because there are numerous lifting lugs with complex distributions, and extremely high requirements are placed on the cutting quality and equipment stability. Therefore, the design of assembling the first guide wheel group 4, the second guide wheel group 5, and the third guide wheel group 6 on the left and right sides of the driving wheel group 3 in a mirror-symmetrical manner is the result of a great deal of creative work, which brings significant technical benefits:

[0044] 1. Optimize the cutting force distribution: During the cutting process of ship lugs, the uniform distribution of the cutting force is crucial. The mirror-symmetrically assembled guide wheel group enables the cutting rope 7 to have highly consistent tensile and frictional forces on both the left and right sides when driven by the driving wheel group 3. This means that the cutting force can act evenly on the lug, avoiding cutting deviation caused by uneven force, greatly improving the cutting accuracy, ensuring the flat surface of the lug after cutting, and meeting the high-precision requirements of shipbuilding. In the design of traditional cutting equipment, such a special scenario as ship lug cutting is rarely considered for such delicate force distribution optimization. This design is based on in-depth understanding of shipbuilding technology and a large amount of practical exploration, and thus this innovative symmetric assembly method is proposed.

[0045] 2. Enhance the operation stability of the equipment: The ship operation environment is complex, and the operation stability of the equipment directly affects the production progress and quality. The mirror-symmetric layout of the guide wheel group makes the center of gravity distribution of the entire cutting system more balanced. When the driving wheel group 3 drives the cutting rope 7 to rotate at high speed, the symmetric guide wheel groups on both sides can provide stable support and guiding force, effectively reducing the vibration and shaking of the equipment. Compared with the asymmetric layout, this design greatly improves the stability of the equipment during long-term and high-intensity cutting operations, reduces the risk of equipment failure, and ensures the continuity of the lug cutting work during shipbuilding. This stability design for the harsh working conditions of shipbuilding is determined after fully considering the actual needs of ship operations and through repeated tests and improvements, reflecting a large amount of creative thinking and practice.

[0046] 3. Improve the cutting efficiency and consistency: In shipbuilding, a large number of lugs need to be cut, and the consistency of efficiency and cutting quality is crucial. The mirror-symmetrically assembled guide wheel group ensures that the running state of the cutting rope 7 is highly consistent at different positions. No matter which lug is cut, the cutting rope can work in the same optimal state, thus improving the overall cutting efficiency. At the same time, due to the consistency of cutting conditions, the cutting quality of each lug can be effectively guaranteed, avoiding quality differences caused by fluctuations in cutting parameters. This symmetric structure designed to meet the large-scale and high-quality lug cutting requirements in shipbuilding is an effective solution obtained through in-depth analysis of the shipbuilding process and pain points and a large number of innovative attempts.

[0047] Optionally, the rotation plane of the driving wheel group 3 is parallel to the rotation plane of the first guide wheel group 4, and the rotation plane is parallel to the first movement direction of the cutting rope 7, and the first movement direction causes the cutting rope 7 to be tensioned along the Z-axis direction. For example, the rotation planes here are all perpendicular to the working surface on the hull. Specifically, the first movement direction is, for example, parallel to the working surface on the hull. Of course, in other embodiments, the first movement direction may also be perpendicular to the opposite surface.

[0048] Preferably, the rotation plane of the driving wheel set 3 and the rotation plane of the first guide wheel set 4 are designed to be parallel, and this rotation plane is parallel to the first movement direction in which the cutting rope 7 is tensioned along the Z-axis direction. This is the result of in-depth analysis of the actual situation of ship operations and full consideration of various influencing factors, and is achieved through a large amount of creative work, with many significant technical advantages:

[0049] 1. Precise and efficient tension control: The materials and specifications of ship lugs are diverse, and extremely strict requirements are imposed on the tension of the cutting rope 7. By making the rotation planes of the driving wheel set 3 and the first guide wheel set 4 parallel and combining with the design of tensioning along the Z-axis direction, precise regulation of the tension of the cutting rope 7 can be achieved. During the actual cutting process, when cutting lugs of different thicknesses or hardnesses, the rotational speed of the driving wheel set 3 or the position of the first guide wheel set 4 can be accurately adjusted according to requirements, thereby precisely changing the tension degree of the cutting rope 7 along the Z-axis direction. This precise tension control not only ensures that the cutting rope is always in the best working state, improves cutting efficiency, but also effectively avoids problems such as cutting rope breakage or cutting quality degradation caused by improper tension. In the design of traditional cutting equipment, it is rarely possible to achieve such precise tension control for the complex working conditions of ship lug cutting. This design is based on a deep understanding of ship manufacturing processes and a large amount of practical exploration, and a unique tension regulation system has been successfully constructed.

[0050] 2. Optimize the cutting force transmission path: The ship operation environment is complex, and the distribution positions of lugs are diverse. The effective transmission of cutting force during the cutting process is crucial. The parallel design of the rotation planes of the driving wheel set 3 and the first guide wheel set 4 enables the driving force received by the cutting rope 7 during operation to be transmitted evenly and smoothly along the parallel rotation planes. When the cutting rope 7 contacts the lug for cutting, this optimized force transmission path can ensure that the cutting force acts vertically and stably on the surface of the lug, avoiding cutting deviation or lug damage caused by uneven force transmission. For example, when cutting some lugs with irregular shapes, this design can ensure that the cutting force is always concentrated on the part that needs to be cut, improving cutting accuracy and quality. This force transmission optimization scheme designed for the complex shapes and position distributions of ship lugs was determined and applied after a large amount of mechanical analysis and actual testing.

[0051] 3. Adapt to complex hull working surfaces: The hull structure of a ship is complex, and the shapes of working surfaces are diverse, including vertical surfaces, horizontal surfaces, and surfaces at various inclined angles. The rotating plane is designed to be perpendicular to the working surface on the hull (and can also flexibly adapt to be perpendicular to the working surface or other special angles in other embodiments), enabling the lug cutting wire saw machine to work efficiently on different types of working surfaces. Whether cutting lugs on the vertical side plates of the ship's hull or operating on horizontal surfaces such as decks, the device can adjust its own posture and utilize the parallel rotating plane and specific tensioning direction to ensure that the cutting wire 7 maintains the best cutting angle and tensioning state with the working surface. This powerful adaptability greatly expands the application scope of the device in shipbuilding and can meet the cutting requirements of lugs in various parts of the ship. This multi-adaptive structure designed for the complex working environment of ships is finally formed after comprehensive research and analysis of different working surfaces of ships and repeated innovation and improvement.

[0052] Optionally, the driving wheel shafts 31 of the driving wheel set 3 are parallel to the respective guide wheel shafts 41 in the first guide wheel set 4.

[0053] For the complex working conditions of lug cutting, the design that the driving wheel shafts 31 of the driving wheel set 3 are parallel to the respective guide wheel shafts 41 in the first guide wheel set 4 is a delicate concept obtained through a lot of creative work after in-depth study of the actual needs of ship operations, the many challenges faced, and the limitations of existing technologies, and has significant technical advantages in many aspects:

[0054] 1. Ensure the stable operation of the cutting wire: During the ship lug cutting process, the stable operation of the cutting wire 7 plays a decisive role in cutting quality and efficiency. The design with the driving wheel shaft 31 parallel to the guide wheel shaft 41 can ensure that the cutting wire 7 runs smoothly around each guide wheel under the drive of the driving wheel set 3. Due to the parallelism of the wheel shafts, the lateral forces acting on the cutting wire 7 during operation are effectively balanced, avoiding problems such as cutting wire deviation, jamming, and even breakage caused by non-parallel wheel shafts. In the actual operation in a shipbuilding workshop, there are numerous lugs with a wide distribution, and the cutting operation lasts for a long time. If the cutting wire frequently malfunctions, it will seriously affect the production progress. This design provides a stable running track for the cutting wire 7 through the ingenious layout of parallel wheel shafts, greatly improving the reliability and stability of the device operation and ensuring the continuity and efficiency of the cutting work. This extreme pursuit of the running stability of the cutting wire is achieved through repeated attempts and improvements during the long-term observation and practice of lug cutting operations in shipbuilding.

[0055] 2. Optimize power transmission and cutting force distribution: Ship lugs are made of various materials with different hardnesses and thicknesses, and have quite different requirements for cutting force. The driving wheel shaft 31 is parallel to the guide wheel shaft 41, enabling the driving wheel set 3 to transmit the driving force to the cutting rope 7 evenly and efficiently. During the cutting process, this parallel layout helps to evenly distribute the cutting force across the contact surface between the cutting rope 7 and the lug, avoiding uneven cutting or lug damage caused by concentrated cutting force in a local area. For example, when cutting large thick-walled lugs, the parallel wheel shaft structure ensures that the cutting rope 7 is evenly stressed throughout its entire length, fully exerting its cutting ability and improving cutting efficiency and quality. Compared with traditional cutting equipment designs, this optimized solution for power transmission and cutting force distribution to meet the special requirements of ship lug cutting requires in-depth analysis of the mechanical principles during the cutting process and a large number of simulations and tests in combination with the actual working conditions of shipbuilding before it can be finally determined.

[0056] 3. Improve the adjustability and adaptability of the equipment: Shipbuilding processes are complex, and there are differences in the design and installation positions of lugs for different types of ships. The design with the driving wheel shaft 31 parallel to the guide wheel shaft 41 provides excellent adjustability and adaptability for the equipment. During actual operations, the relative positions and spacings of the driving wheel set 3 and the first guide wheel set 4 can be flexibly adjusted according to the specific position, shape, and size of the lug, while maintaining the parallel relationship of the wheel shafts. For example, when encountering lugs with a small spacing or a special installation position, the position of the guide wheel set can be finely adjusted to enable the cutting rope 7 to accurately reach the cutting position and still maintain a stable operating state and good cutting effect. This design that can flexibly adapt to various complex ship lug cutting scenarios is achieved through a large number of innovative attempts and optimizations on the basis of fully considering the diversity and complexity of the shipbuilding industry.

[0057] Preferably, the driving wheel shaft 31 of the driving wheel set 3 and the guide wheel shafts 41 in some of the first guide wheel sets 4 are assembled on the frame 1 perpendicular to the frame 1, and the guide wheel shafts 41 in the other part of the first guide wheel sets 4 are directly assembled on the frame 1 perpendicular to the frame 1, so that the driving wheel shaft 31 of the driving wheel set 3 is parallel to the guide wheel shafts 41 in the first guide wheel set 4, and the driving wheel set 3 is assembled on the corresponding driving wheel shaft 31, the first guide wheel set 4 is assembled on the corresponding guide wheel shaft 41, and the rotation plane of the driving wheel set 3 is parallel to the rotation plane of the first guide wheel set 4.

[0058] Preferably, the driving wheel shaft 31 of the driving wheel set 3 and the guide wheel shafts 41 of some of the first guide wheel sets 4 are assembled on the frame 1 in a manner perpendicular to the frame 1, and the guide wheel shafts 41 of the other part of the first guide wheel sets 4 are also directly assembled perpendicular to the frame 1, so as to achieve a series of parallel relationships between the driving wheel set 3 and the first guide wheel set 4, bringing many technical benefits:

[0059] 1. Excellent structural stability: During the shipbuilding process, the workshop environment is complex, and the equipment may be subject to various vibrations and external forces. Through the perpendicular assembly of the driving wheel shaft 31 and the guide wheel shaft 41 on the frame 1, a solid mechanical structure is constructed. The perpendicular assembly method makes the installation of the driving wheel set 3 and the first guide wheel set 4 on the frame 1 more firm, capable of effectively resisting external forces from different directions, and reducing the shaking and displacement of the equipment during operation. For example, in a shipbuilding workshop, there may be vibrations from the operation of large mechanical equipment around, or impact during material handling. If the equipment structure is unstable, the running trajectory of the cutting rope 7 will be affected, resulting in a decrease in cutting accuracy. However, with its unique perpendicular assembly method, this design ensures that the driving wheel set 3 and the first guide wheel set 4 can still remain stable in a complex external force environment, providing reliable support and guidance for the cutting rope 7, and ensuring the continuity and accuracy of the cutting operation.

[0060] 2. Precise cutting force transmission and cutting accuracy guarantee: The cutting accuracy of the ship's lifting lug is directly related to the safety of the overall ship structure and the smooth progress of subsequent assembly work. The design with the rotation planes of the driving wheel set 3 and the first guide wheel set 4 being parallel and the wheel shafts being parallel enables the driving wheel set 3 to accurately and evenly transmit the driving force to the cutting rope 7 under the drive of the cutting drive mechanism 2. Due to the parallelism of the wheel shafts, the tension received by the cutting rope 7 during operation remains consistent throughout its length. Thus, when cutting the lifting lug, the cutting force can act evenly on the surface of the lifting lug. Taking the cutting of the lifting lug at a key part of the ship with high-precision requirements as an example, this precise cutting force transmission method can ensure that the cutting surface is flat and smooth, with the error controlled within a very small range, avoiding problems such as cutting deviation and lifting lug deformation caused by uneven cutting force, and greatly improving the cutting quality.

[0061] 3. Flexible adaptability and adjustability: The shipbuilding process is rich and diverse, and there are significant differences in the sizes, shapes, and installation positions of the lugs of different types of ships. By adopting different assembly methods for some of the first guide wheel sets 4, this design brings extremely high flexibility and adjustability to the equipment. When encountering lugs in special positions or with special specifications, according to the actual situation, by adjusting the assembly details of some of the guide wheel sets, while maintaining the parallel relationship between the driving wheel set 3 and the first guide wheel set 4, the cutting rope 7 can accurately reach the cutting position and maintain the best tension state and running trajectory. For example, when cutting lugs in narrow spaces or with special angles, the cutting rope 7 can be skillfully guided around obstacles by finely adjusting the guide wheel sets with specific assembly methods to complete precise cutting.

[0062] Preferably, a guide wheel assembly plate 11 is assembled on the frame 1. The guide wheel shafts 41 of some of the first guide wheel sets 4 are indirectly assembled on the guide wheel assembly plate 11 in a manner perpendicular to the frame 1, and the guide wheel shafts 41 of the other part of the first guide wheel sets 4 are directly assembled on the frame 1 in a manner perpendicular to the frame 1, while the driving wheel shaft 31 of the driving wheel set 3 is assembled on the frame 1 in a manner perpendicular to the frame 1, with the driving wheel shaft 31 of the driving wheel set 3 being parallel to the guide wheel shafts 41 of the first guide wheel sets 4.

[0063] Preferably, the design of assembling the guide wheel assembly plate 11 on the frame 1 and adopting a unique assembly method has significant technical advantages:

[0064] 1. Precise and flexible adjustment of the cutting rope tension: During the cutting of ship lugs, for lugs of different materials and thicknesses, it is necessary to accurately adjust the tension of the cutting rope 7 to ensure the cutting quality and efficiency. By indirectly assembling the guide wheel shafts 41 of some of the first guide wheel sets 4 on the guide wheel assembly plate 11, this part of the guide wheel set can move flexibly with the guide wheel assembly plate 11. For example, when cutting lugs made of harder materials, the distance between this part of the guide wheels and other wheel sets can be increased by moving the guide wheel assembly plate 11, thereby increasing the tension of the cutting rope 7 and improving the cutting ability; when cutting softer or thinner lugs, the reverse operation is performed to reduce the tension to avoid overcutting. Traditional cutting equipment often lacks such a precise and flexible tension adjustment mechanism, and this solution is achieved by innovatively introducing the guide wheel assembly plate 11 and the corresponding assembly method, greatly enhancing the adaptability of the equipment to different cutting requirements.

[0065] 2. Enhance equipment stability and reliability: The environment in a shipbuilding workshop is complex, and equipment is vulnerable to disturbances such as vibration and collision. The driving wheel shaft 31 and some of the guide wheel shafts 41 are vertically assembled on the frame 1, constructing a stable mechanical support structure for the equipment. In particular, some of the guide wheel groups are connected to the frame 1 through the guide wheel assembly plate 11. While ensuring the parallel relationship of the wheel shafts, the stress points during equipment operation are dispersed. When other large equipment in the workshop runs and generates vibration, the guide wheel assembly plate 11 can play a certain buffering role, reducing the impact of vibration on the running stability of the cutting rope 7 and ensuring a smooth and continuous cutting process. This stability design for the harsh working environment of shipbuilding greatly improves the reliability of the equipment in complex environments.

[0066] 3. Adapt to complex ship structures and lugs layouts: Ship structures are complex, and the distribution positions of lugs vary. There are cases where they are installed in narrow spaces, corners, or at special angles. The presence of the guide wheel assembly plate 11 in this design endows the equipment with excellent adaptability. For lugs in special positions, by adjusting the installation angle or position of the guide wheel assembly plate 11, while maintaining the parallel relationship between the driving wheel group 3 and the first guide wheel group 4, the cutting rope 7 can be cleverly guided to the cutting position. For example, when encountering a lug at the angle of a ship bulkhead, the guide wheel assembly plate 11 can be installed at an appropriate inclination so that the guide wheel group can reasonably guide the cutting rope 7 to bypass obstacles and complete precise cutting.

[0067] Preferably, the guide wheel assembly plate 11 is assembled on the frame 1 in a manner that forms a gap with the frame 1, and a first sliding pair 12 is assembled on the frame 1. The first sliding pair 12 is located within the gap and is connected to the guide wheel assembly plate 11, so that the guide wheel assembly plate 11 can slide on the frame 1 through the first sliding pair 12, thereby driving a part of the first guide wheel group 4 to slide, and thus adjusting the tension of the cutting rope 7. For example, in one case, it is convenient for replacing or repairing the cutting rope 7, or mainly for adjusting the tension of the cutting rope 7 rather than replacing or repairing. Here, the specific technical purpose of the tension adjustment is not uniquely defined.

[0068] In this special and complex application scenario of shipbuilding, the work of cutting lugs faces many challenges. Ship structures are diverse, and the materials, sizes, and installation positions of lugs are different, which requires the lug cutting wire saw machine to have a high degree of flexibility and precise adjustment ability. Therefore, the design of the guide wheel assembly plate 11 and the frame 1 forming a gap and being connected through the first sliding pair 12 has significant technical advantages:

[0069] 1. Precise and convenient tension adjustment: During the cutting process of ship lifting lugs, different lug materials and thicknesses have different requirements for the tension of the cutting rope 7. Traditional cutting equipment often has difficulty achieving precise and convenient tension adjustment. In this design, the guide wheel assembly plate 11 can slide on the frame 1 through the first sliding pair 12, thereby driving part of the first guide wheel group 4 to slide, and the tension of the cutting rope 7 can be adjusted extremely precisely. For example, when cutting high-hardness alloy steel lugs, it is necessary to increase the tension of the cutting rope 7 to ensure cutting efficiency and quality. At this time, the operator only needs to control the first sliding pair 12 to move the guide wheel assembly plate 11 an appropriate distance to quickly increase the tension; when cutting lugs of softer materials, the tension can be reduced accordingly. This precise and convenient adjustment method greatly improves the adaptability and efficiency of cutting operations.

[0070] 2. Efficient equipment maintenance and replacement: In a ship manufacturing workshop, the efficiency of equipment maintenance and repair directly affects the production progress. When the cutting rope 7 needs to be replaced or repaired, traditional equipment may require cumbersome disassembly steps, consuming a large amount of time and manpower. In this design, since the guide wheel assembly plate 11 can slide through the first sliding pair 12, when replacing or repairing the cutting rope 7, the operator can easily slide the guide wheel assembly plate 11 to a suitable position, greatly increasing the operation space for replacing or repairing the cutting rope 7, and making the operation process simple and efficient. This design fully considers the actual operation requirements on the ship manufacturing site, greatly reducing the equipment downtime and improving the production efficiency.

[0071] 3. Adapt to complex working conditions and diverse requirements: The ship manufacturing environment is complex, with interference factors such as vibration and dust. At the same time, the distribution and specifications of lugs vary greatly. Through the special connection method between the guide wheel assembly plate 11 and the frame 1 in this design, not only can the tension be precisely adjusted and the equipment be conveniently maintained, but also the stability of the equipment can be maintained under different working conditions. For example, in an area with large vibrations, the gap between the guide wheel assembly plate 11 and the frame 1 and the design of the first sliding pair 12 can play a certain buffering role, reducing the impact of vibration on the operation of the cutting rope 7 and ensuring the stability of cutting operations. Moreover, this design can flexibly adjust the tension of the cutting rope 7 according to the specific situation of lugs in different ship projects to meet diverse cutting requirements.

[0072] Preferably, the first sliding pair 12 is assembled on the frame 1 in a manner perpendicular to the extending direction of the guide wheel assembly plate 11, so that the guide wheel assembly plate 11 can slide on the frame 1 along or away from the direction perpendicular to the working surface on the hull through the first sliding pair 12, thereby adjusting the tension of the cutting rope 7 in the direction perpendicular to the working surface on the hull. In other embodiments, it is also possible to make the guide wheel assembly plate 11 slide on the frame 1 along the direction parallel to the working surface on the hull (such as the left-right direction) through the first sliding pair 12. At this time, only the assembly direction of other structures needs to be adjusted adaptively. In some other embodiments, it can also be modified to slide along a direction having a certain included angle with the working surface on the hull according to needs.

[0073] Considering that the diversity of the hull structure results in different directions and forms of the working surface, and the positions, materials, and specifications of the lifting lugs are also very different, this requires the lifting lug cutting wire saw machine to have extremely high flexibility and precise adjustment performance. For this reason, in the above solution, the first sliding pair 12 is assembled on the frame 1 in a variety of selectable ways, so as to realize the design of diversified sliding directions of the guide wheel assembly plate 11, which has extremely significant technical advantages:

[0074] 1. Precise adaptation of the tension adjustment for different working surfaces: The ship's working surface includes vertical surfaces, horizontal surfaces, and various inclined surfaces. When cutting the lifting lug, the characteristics of different working surfaces require that the tension of the cutting rope 7 in the direction perpendicular to the working surface can be precisely adjusted. For example, when cutting the lifting lug on the vertical ship's side plate, due to the special directions of gravity and cutting force, it is necessary to accurately adjust the vertical tension of the cutting rope 7 to ensure smooth cutting and avoid the shaking of the cutting rope affecting the cutting accuracy. In this design, the first sliding pair 12 is assembled perpendicular to the extending direction of the guide wheel assembly plate 11, so that the guide wheel assembly plate 11 can slide along or away from the direction perpendicular to the hull working surface, thereby precisely controlling the tension of the cutting rope 7 in this direction.

[0075] 2. Flexibly coping with the operation requirements of complex lifting lug distributions: The distribution of ship lifting lugs is extremely complex. Some are arranged longitudinally along the hull, some are distributed transversely, and some are at inclined angles. When the lifting lugs are distributed transversely along the hull, it is difficult for traditional cutting equipment to effectively adjust the tension of the cutting rope to adapt to such a layout. However, this design allows the guide wheel assembly plate 11 to slide on the frame 1 along the direction parallel to the hull working surface (such as the left-right direction) through the first sliding pair 12. By adaptively adjusting the assembly direction of other structures, the tension and running trajectory of the cutting rope 7 in the parallel working surface direction can be flexibly changed, so as to skillfully adapt to the complex lifting lug distribution situation and ensure that each lifting lug can be precisely cut.

[0076] 3. Fully adaptable to diverse hull structures and working conditions: Ship structures not only have conventional vertical and horizontal working surfaces, but also have many structural parts with special angles, such as the diagonal braces and special-shaped bulkheads of the hull. When cutting the lifting lugs at these locations, the cutting rope 7 needs to act on the lifting lugs at a specific angle, and traditional equipment cannot meet such requirements at all. This design innovatively proposes that the first sliding pair 12 can be modified to enable the guide wheel assembly plate 11 to slide in a direction with a certain angle to the hull working surface. Through this unique design, the tension and running direction of the cutting rope 7 can be accurately adjusted according to the actual angle of the special structural parts of the hull, so that the cutting operation can be carried out smoothly.

[0077] Preferably, the first sliding pair 12 includes a first slider 121 and a first slide rail 122, the first slide rail 122 is mounted on the frame 1, the first slider 121 is mounted on the guide wheel assembly plate 11 and is slidably connected to the first slide rail 122, so that the guide wheel assembly plate 11 can slide on the frame 1 through the first sliding pair 12. Alternatively, the first slider 121 is mounted on the frame 1, the first slide rail 122 is mounted on the guide wheel assembly plate 11 and is slidably connected to the first slider 121, so that the guide wheel assembly plate 11 can slide on the frame 1 through the first sliding pair 12.

[0078] In the field of shipbuilding, the environment and task requirements faced by the lug cutting operation are extremely complex. The hull structure is diverse, and the lugs are widely distributed and of different specifications, which requires the adjustment structure of the lug cutting wire saw machine to have high precision, high stability and good adaptability. To this end, the first sliding pair 12 adopts a design method of combining the first slider 121 and the first slide rail 122. It seems simple, but in fact it is an ingenious solution obtained after fully considering the various characteristics of the shipbuilding application scenario and a lot of creative work, and it has many significant technical advantages:

[0079] 1. High-precision tension adjustment is achieved: During the cutting process of the ship's lifting lugs, the adjustment accuracy of the tension of the cutting rope 7 directly affects the cutting quality. In traditional adjustment mechanisms, it is difficult to achieve fine control of the tension. The design of the first sliding pair 12, whether the first slide rail 122 is assembled on the frame 1, the first slider 121 is assembled on the guide wheel assembly plate 11, or the opposite assembly method, can ensure that the guide wheel assembly plate 11 can slide smoothly and accurately on the frame 1. For example, when cutting the lifting lugs of key parts of ships with high precision requirements, the operator can fine-tune the first sliding pair 12 to move the guide wheel assembly plate 11 a very small distance, thereby accurately changing the tension of the cutting rope 7 and meeting the stringent requirements of the cutting process on the tension.

[0080] 2. Excellent structural stability and reliability: The environment in a ship manufacturing workshop is complex, with interference factors such as vibration and collision. The stability of equipment is crucial. The cooperation between the first slider 121 and the first slide rail 122 forms a stable sliding connection structure. The first slide rail 122 provides a stable track for the sliding of the first slider 121, and the first slider 121 can reliably drive the guide wheel assembly plate 11 to move. When other large equipment in the workshop is running and generating strong vibrations, the first sliding pair 12 can effectively buffer and absorb part of the vibration energy, ensuring the sliding stability of the guide wheel assembly plate 11, and further ensuring that the tension adjustment of the cutting rope 7 is not interfered, maintaining the continuity and stability of the cutting operation.

[0081] 3. High adaptability and flexibility: The structure of a ship is complex, and the positions and installation angles of the lugs are different. This requires the adjustment structure of the cutting rope saw machine to be able to adapt to various working scenarios. The two interchangeable assembly methods of the first sliding pair 12 bring extremely high adaptability and flexibility to the equipment. When encountering lugs with different positions and angles, a more suitable assembly method can be selected according to the actual situation, so that the guide wheel assembly plate 11 can slide in the best way, thereby adjusting the tension and running trajectory of the cutting rope 7. For example, when cutting a lug in a narrow space, choosing the method of assembling the first slider 121 on the frame 1 and the first slide rail 122 on the guide wheel assembly plate 11 may be more convenient for the installation and operation of the equipment, enabling the cutting rope 7 to reach the cutting position smoothly and maintain an appropriate tension.

[0082] Preferably, a telescopic structure 13 is also assembled on the frame 1. One end of the telescopic structure is connected to a part of the first guide wheel set 4, and the other end is fixed on the frame 1, so as to push a part of the first guide wheel set 4 to slide through the expansion and contraction of the telescopic structure 13, and adjust the distances between a part of the first guide wheel set 4 and another part of the first guide wheel set 4 and the driving wheel set 3 respectively, thereby realizing the tension adjustment of the cutting rope 7. For example, the tension adjustment of the cutting rope 7 can be specifically realized through the above-mentioned first sliding pair 12.

[0083] Preferably, considering the specific application scenario in ship manufacturing, the lug cutting work has extremely high requirements for the performance and adaptability of the equipment. Considering the complexity of the ship structure, the diversity of lug materials and distributions, it is not easy to design equipment that can cut lugs efficiently and accurately. The design of assembling the telescopic structure 13 on the frame 1 and connecting it to a part of the first guide wheel set 4 is based on full consideration of the actual needs of ship manufacturing, and is obtained after a large number of practical explorations and innovative thinking, and has significant technical advantages:

[0084] 1. Accurate and flexible tension adjustment: During the cutting process of the ship's lifting lugs, different lifting lug materials, thicknesses and cutting positions have different requirements for the tension of the cutting rope 7. Traditional cutting equipment is often difficult to adjust the tension accurately and flexibly according to actual conditions. The setting of the telescopic structure 13 allows the operator to accurately adjust the position of a part of the first guide wheel group 4 by controlling the extension and retraction of the telescopic structure according to specific cutting requirements, thereby changing the distance between this part of the guide wheel group and the other part of the first guide wheel group 4 and the driving wheel group 3. For example, when cutting a lifting lug made of a harder material, the telescopic structure 13 is extended to increase the distance between the guide wheel groups, thereby increasing the tension of the cutting rope 7 and improving the cutting efficiency and quality; when cutting a softer or thinner lifting lug, the telescopic structure is shortened to reduce the tension and avoid excessive cutting.

[0085] 2. Improve the automation level and operation convenience of the equipment: In the shipbuilding workshop, improving the automation level and operation convenience of the equipment is crucial to improving production efficiency. The introduction of the telescopic structure 13 makes the tension adjustment process of the cutting rope 7 more automated and convenient. The operator does not need to perform cumbersome manual adjustments like traditional equipment. The tension can be adjusted quickly and accurately by controlling the telescopic action of the telescopic structure. This not only reduces the labor intensity of the operator, but also greatly shortens the adjustment time and improves production efficiency. At the same time, the telescopic structure 13 is combined with the first sliding pair 12 to provide a variety of options for adjusting the tension, further enhancing the operational flexibility and adaptability of the equipment.

[0086] 3. Enhance the stability and reliability of the equipment: The shipbuilding environment is complex, with interference factors such as vibration and impact. The stability and reliability of the equipment directly affect the quality and efficiency of the cutting operation. One end of the telescopic structure 13 is fixed to the frame 1, and the other end is connected to a part of the first guide wheel group 4. This connection method ensures that the guide wheel group can flexibly adjust its position while also providing stable support for the equipment. When the equipment is subject to external interference during operation, the telescopic structure 13 can effectively buffer and absorb part of the impact force, reduce the shaking and displacement of the guide wheel group, thereby ensuring the stability of the tension of the cutting rope 7 and improving the operational stability and reliability of the equipment.

[0087] Preferably, the telescopic structure 13 can be telescopic in a direction perpendicular to the working surface on the hull (moving away from or approaching), so as to adjust the distance between one part of the first guide wheel group 4 and another part of the first guide wheel group 4 and the driving wheel group 3.

[0088] Preferably, in the challenging specific application scenario of shipbuilding, the lug cutting operation faces many complex situations. The hull working surface has different shapes, and the position, material and specifications of the lugs are different, which puts extremely high demands on the performance of the lug cutting wire saw machine. The design of allowing the telescopic structure 13 to telescope in a direction perpendicular to the hull working surface to adjust the spacing of the guide wheel group is by no means easy to obtain, but is an ingenious idea born after fully considering the actual needs of shipbuilding and undergoing a lot of creative labor, and has significant technical advantages:

[0089] 1. Tension control that accurately adapts to the characteristics of the working surface: The working surface of a ship includes various forms such as vertical surfaces and inclined surfaces. When cutting the lifting lugs on a vertical working surface, due to the combined effects of gravity and cutting force, the tension of the cutting rope 7 needs to be finely adjusted to ensure smooth cutting. The telescopic structure 13 is telescopic in a direction perpendicular to the working surface, which can accurately change the spacing between part of the first guide wheel group 4 and other wheel groups, thereby accurately regulating the tension of the cutting rope 7 in the vertical direction. For example, when cutting thick-walled lifting lugs on the vertical side panels of the ship's side, it is necessary to increase the tension to improve the cutting efficiency. This requirement can be accurately achieved by extending the telescopic structure 13 and expanding the spacing between the guide wheel groups. When cutting thinner lifting lugs, the telescopic structure is contracted to reduce the tension to prevent excessive wear of the cutting rope or damage to the lifting lugs.

[0090] 2. High flexibility to adapt to complex lifting lug layouts: The lifting lugs of ships are widely distributed and complexly arranged, and some lifting lugs are in small spaces or at special angles. When the lifting lugs are closely arranged near the vertical working surface, it is difficult for traditional equipment to effectively adjust the tension of the cutting rope to adapt to this layout. The design of the telescopic structure 13 to telescope in the vertical direction makes the equipment extremely flexible when facing such complex lifting lug layouts. By accurately controlling the telescopic amount of the telescopic structure, the position of the guide wheel group can be flexibly adjusted to cleverly avoid surrounding obstacles, while ensuring that the cutting rope 7 accurately cuts the target lifting lug under appropriate tension.

[0091] 3. Improve the stability of the equipment under complex working conditions: The shipbuilding workshop environment is harsh, with interference factors such as vibration and dust. The telescopic structure 13 is telescopic in a direction perpendicular to the working surface, which adjusts the spacing between the guide wheels and enhances the stability of the equipment under complex working conditions. When other large equipment in the workshop vibrates, the telescopic structure 13 that telescopes in the vertical direction can effectively buffer and absorb part of the vibration energy by using its own telescopic characteristics, reduce the shaking of the guide wheels, ensure the stability of the tension of the cutting rope 7, and maintain the continuity of the cutting operation.

[0092] Preferably, one end of the telescopic structure 13 is fixed on the guide wheel assembly plate 11, and the other end is fixed on the frame 1, so that the guide wheel assembly plate 11 can slide along the frame through the first sliding pair 12, thereby adjusting the distance between a part of the first guide wheel group 4 and another part of the first guide wheel group 4 and the driving wheel group 3 respectively.

[0093] Preferably, a telescopic structure mounting plate 15 is assembled on the frame 1. One end of the telescopic structure 13 is fixed on the guide wheel assembly plate 11, and the other end is fixed on the telescopic structure mounting plate 15. The telescopic structure mounting plate 15 and the guide wheel assembly plate 11 form an up-and-down positional relationship on the frame 1 (which may be a left-and-right positional relationship in other scenarios).

[0094] Preferably, the number of the telescopic structures 13 is not limited and can be flexibly configured according to specific requirements. For example, one telescopic structure 13 can be arranged between every two of the above-mentioned part of the first guide wheel groups 4.

[0095] Preferably, the specific implementation of the above-mentioned telescopic structure is not limited. For example, it can be in the form of a cylinder or an electric push rod.

[0096] Preferably, when the distances between a part of the first guide wheel group 4 and another part of the first guide wheel group 4 and the driving wheel group 3 respectively reach the target distances, the telescopic degree of the telescopic structure 13 is locked.

[0097] For the above-mentioned "assembly", other specific implementations are not uniquely limited. For example, it can be in the way of nuts and studs, or other equivalent ways.

[0098] Preferably, the number of the driving wheel groups 3 is 1, and the number of the first guide wheel groups 4 is 6. Three first guide wheel groups 4 are assembled on the left and right sides of the driving wheel group 3 in a mirror-symmetrical manner, so that the six first guide wheel groups 4 form a staggered up-and-down positional relationship with 4 in the upper region of the frame and 2 in the lower region, so as to tension in the Z-axis direction (such as the direction perpendicular to the working surface on the hull) in the up-and-down direction. Among them, 4 first guide wheel groups can slide up and down under the action of the first sliding pair 12, and the other 2 remain stationary, thereby realizing the adjustment of the tension of the cutting rope in the vertical direction.

[0099] Optionally, the rotation plane of the driving wheel group 3 is perpendicular to the rotation plane of the second guide wheel group 5, and the rotation plane is parallel to the second movement direction of the cutting rope 7 so that the second movement direction is perpendicular to the first movement direction, and the second movement direction makes the cutting rope 7 tension along the Y-axis direction.

[0100] Optionally, the second direction is, for example, along the X direction (including from front to back or from back to front), and the first movement direction is the Z direction (including from top to bottom or from bottom to top), which can be specifically determined according to the application scenario.

[0101] Optionally, the driving wheel shafts 31 of the driving wheel set 3 are perpendicular to the guide wheel shafts 51 of each guide wheel in the second guide wheel set 5.

[0102] Optionally, for example, the guide wheel shafts 51 of each guide wheel in the second guide wheel set 5 are along a direction, and the driving wheel shafts 31 of the driving wheel set 3 are along the X direction.

[0103] Optionally, the frame 1 includes a vertical frame 1A and a horizontal frame 1B. The driving wheel set 3, the first guide wheel set 4, the first slide rail 122, the telescopic structure 13, and the telescopic structure mounting plate 15 are assembled on the vertical frame 1A, and the guide wheel shafts 51 of each guide wheel in the second guide wheel set 5 are assembled on the horizontal frame 1B.

[0104] Preferably, during the shipbuilding process, ear cutting faces many challenges, such as limited working space, different cutting requirements for ears at different positions, and the need for the equipment to have good stability and adjustability. The solution of designing the frame 1 to consist of a vertical frame 1A and a horizontal frame 1B and assembling each component in a specific manner is obtained after fully considering these factors and a large amount of creative work, and has significant technical advantages:

[0105] 1. Optimize the equipment space layout and operation convenience: The space in a shipbuilding workshop is usually relatively crowded, and the space layout of the equipment is crucial. Assembling the driving wheel set 3, the first guide wheel set 4, the first slide rail 122, the telescopic structure 13, and the telescopic structure mounting plate 15 on the vertical frame 1A enables these components to be arranged in an orderly manner in the vertical direction, effectively utilizing the vertical space, avoiding mutual interference between components, and providing a more convenient operation space for the operator. For example, when adjusting the position of the first guide wheel set 4 or maintaining the telescopic structure 13, the operator can operate in the relatively open space around the vertical frame 1A without having to work difficultly among the intricate equipment components. At the same time, the guide wheel shafts 51 of the second guide wheel set 5 are assembled on the horizontal frame 1B, forming a reasonable space partition with the components on the vertical frame 1A. This layout method fully considers the space limitations and operation processes in a shipbuilding workshop, greatly improving the operation convenience of the equipment.

[0106] 2. Improve the structural stability and cutting accuracy of the equipment: During the ship operation process, there are various vibrations and external force interferences, and the stability of the equipment directly affects the cutting accuracy. The frame structure composed of the vertical frame 1A and the horizontal frame 1B provides a stable support framework for the equipment. Key components such as the driving wheel set 3 and the first guiding wheel set 4 are assembled on the vertical frame 1A, making the center of gravity distribution of the equipment in the vertical direction more reasonable and enhancing the ability of the equipment to resist vibrations and external forces in the vertical direction. The second guiding wheel set 5 is assembled on the horizontal frame 1B and works together with the vertical frame 1A to further improve the overall structural stability of the equipment. For example, during the cutting process, when other large equipment in the workshop runs and generates vibrations, this reasonable frame structure can effectively buffer and disperse the vibration energy, ensure the smooth running of the cutting rope 7, thereby improving the cutting accuracy and ensuring the cutting quality of the lifting lugs.

[0107] 3. Enhance the adaptability and cutting flexibility of the equipment: The positions and installation angles of ship lifting lugs are diverse, and the cutting equipment needs to have high adaptability and cutting flexibility. Assembling the driving wheel set 3 and the first guiding wheel set 4 on the vertical frame 1A, through components such as the telescopic structure 13, it is convenient to adjust the tension force and running trajectory of the cutting rope 7 in the vertical direction to meet the cutting requirements of lifting lugs at different height positions. At the same time, the second guiding wheel set 5 is assembled on the horizontal frame 1B, which can guide and adjust the cutting rope 7 in the horizontal direction and cooperate with the components on the vertical frame 1A to achieve all-round cutting of lifting lugs at different angles and positions. For example, for lifting lugs installed at the corners of the hull or with special inclination angles, through the coordinated work of the components on the vertical frame 1A and the horizontal frame 1B, the running direction and tension force of the cutting rope 7 can be flexibly adjusted to ensure accurate cutting of the lifting lugs.

[0108] Optionally, the rotation plane of the driving wheel set 3 is parallel to the rotation plane of the third guiding wheel set 6, and the rotation plane is parallel to the third movement direction of the cutting rope 7 so that the third movement direction is perpendicular to the second movement direction and the first movement direction, and the third movement direction makes the cutting rope 7 tensioned along the X-axis direction.

[0109] Preferably, ship structures are complex and diverse, and lifting lugs are widely distributed and have different angles, which requires the lifting lug cutting wire saw machine to have extremely fine and comprehensive adjustment capabilities. The parallelism between the rotation plane of the driving wheel set 3 and the rotation plane of the third guiding wheel set 6, as well as the design of the relevant movement directions and tension directions, are innovative achievements condensed through a large amount of creative work for the specific application scenario of shipbuilding and have the following technical advantages:

[0110] 1. Achieve precise tensioning and cutting force control in three-dimensional space: The cutting operation of the ship's lifting lug requires extremely high control precision of the tensioning force and cutting force of the cutting rope 7. In actual cutting, due to the complexity of the position and angle of the lifting lug, the tensioning and cutting force control in a single direction far cannot meet the requirements. This design constructs a cutting system that can be precisely regulated in three-dimensional space by making the rotation planes of the driving wheel set 3 and the third guide wheel set 6 parallel and tensioning the cutting rope 7 along the X-axis direction. For example, when cutting a lifting lug located at a complex structure of the hull with a special spatial angle, this design can be used to precisely adjust the tensioning force of the cutting rope 7 in the X-axis direction and cooperate with the tensioning forces in the Z-axis direction (the first movement direction) and the Y-axis direction (the second movement direction), so that the cutting force can act on the lifting lug at the most appropriate angle and strength.

[0111] 2. Enhance the adaptability of the equipment to complex ship structures: Ship structures are rich and diverse, with a large number of irregular parts and narrow spaces, and the lifting lugs are often distributed therein. Traditional cutting equipment is difficult to adapt to this complex environment, while this design significantly enhances the adaptability of the equipment to complex ship structures through a unique layout of the guide wheel set and the design of the movement direction of the cutting rope. When encountering a lifting lug located near a narrow passage inside the hull or a structural member with a complex spatial orientation, the coordinated work of the driving wheel set 3 and the third guide wheel set 6 can guide the cutting rope 7 to accurately reach the cutting position along a specific X-axis direction and maintain an appropriate tensioning force. By cooperating with other guide wheel sets, the cutting rope 7 can move flexibly in three-dimensional space, avoid obstacles, and complete the cutting of the lifting lug at a special position.

[0112] 3. Optimize cutting efficiency and equipment operation stability: In the process of shipbuilding, improving cutting efficiency and ensuring equipment operation stability are crucial. The design of making the rotation planes of the driving wheel set 3 and the third guide wheel set 6 parallel and tensioning the cutting rope 7 along the X-axis direction makes the force transmission during the cutting process more uniform and stable. During the cutting process, each guide wheel set can cooperate to ensure that the cutting rope 7 maintains a stable movement trajectory during high-speed operation, reducing vibrations and shakes caused by unbalanced forces. This not only improves cutting efficiency but also extends the service life of the equipment. For example, when continuously cutting multiple lifting lugs at different positions and angles, the equipment can quickly and stably adjust the tensioning force and movement direction of the cutting rope 7 to achieve efficient and precise cutting.

[0113] Optionally, the driving wheel shaft 31 of the driving wheel set 3 is perpendicular to each guide wheel shaft 61 in the third guide wheel set 6, and each guide wheel shaft 61 in the third guide wheel set 6 is perpendicular to each guide wheel shaft 51 in the second guide wheel set 5.

[0114] Preferably, in the field of shipbuilding, the lug cutting operation faces complex working conditions and strict quality requirements. The ship structure is complex, and the positions and angles of the lugs are variable, requiring the cutting equipment to have a high degree of flexibility, precision, and stability. For this reason, the axles of the above-mentioned driving wheel set 3, second guide wheel set 5, and third guide wheel set 6 are arranged perpendicular to each other. This design is the result of a large amount of in-depth research, repeated experiments, and innovative thinking for this specific application scenario of shipbuilding, and has significant technical advantages:

[0115] 1. Achieve full-range precise guidance and cutting: The shapes, installation positions, and angles of ship lugs are different, posing extremely high requirements for the guidance and cutting direction of the cutting rope 7. The driving wheel axle 31 is perpendicular to the guide wheel axle 61 of the third guide wheel set 6, and the guide wheel axle 61 of the third guide wheel set 6 is perpendicular to the guide wheel axle 51 of the second guide wheel set 5. This unique layout constructs a three-dimensional guidance system. Through this system, the cutting rope 7 can be precisely guided in multiple directions to achieve full-range cutting of lugs at different positions and angles. For example, for lugs installed at the corners of the hull or with special inclination angles, this design enables the cutting rope 7 to accurately fit the lug contour along a specific trajectory for cutting, ensuring that the cutting surface is flat and meets the accuracy requirements.

[0116] 2. Enhance the stability and reliability of the equipment: The environment in the shipbuilding workshop is complex, with interference factors such as vibration and collision. The stability and reliability of the equipment directly affect the smooth progress of the cutting operation. The perpendicular layout of the axles makes the equipment more stable in structure. The driving wheel set 3, second guide wheel set 5, and third guide wheel set 6 are connected by perpendicular axles, forming a stable mechanical structure that can effectively resist external forces from different directions. When other large equipment in the workshop runs and generates vibration, this structure can disperse the vibration energy and reduce the impact on the running stability of the cutting rope 7. For example, during the segmented construction of a ship, surrounding lifting equipment, welding equipment, etc. may cause strong vibrations, while the equipment designed in this way can operate stably, ensuring that the cutting rope 7 is always in the best working state, improving the reliability of the equipment, and guaranteeing the continuity of the cutting operation.

[0117] 3. Improve the adaptability and flexibility of the equipment: The shipbuilding technology is constantly developing, and new ship designs and construction requirements are emerging continuously. The perpendicular layout of the axles in this design endows the equipment with excellent adaptability and flexibility. When facing the cutting tasks of lugs on different types of ships or different parts of the same ship, by adjusting the positions and angles of each guide wheel set and combining the perpendicular axle relationship, the equipment can quickly adapt to new cutting requirements. For example, during the research and development and construction of new ships, there may be some unprecedented lug designs and installation methods. This equipment can flexibly adjust each wheel set to make the cutting rope 7 meet special cutting path and tension requirements.

[0118] Optionally, on each guide wheel shaft 51 in the second guide wheel set 5 (such as along the Y direction) and on each guide wheel shaft 61 in the third guide wheel set 6 (such as along the Z direction), so that each guide wheel shaft 61 in the third guide wheel set 6 is perpendicular to each guide wheel shaft 51 in the second guide wheel set 5.

[0119] Preferably, in a specific application scenario of shipbuilding, the lugs cutting work faces difficulties such as complex ship structures and variable positions and angles of lugs. Setting the guide wheel shaft 51 of the second guide wheel set 5 to be along the Y direction and the guide wheel shaft 61 of the third guide wheel set 6 to be along the Z direction, making the two perpendicular to each other, is conceived through a large amount of creative work and has significant technical advantages in many aspects:

[0120] 1. Construct a precise three-dimensional cutting system: The ship lugs are distributed in various parts of the hull, and their spatial positions and angles vary greatly. Traditional cutting equipment can often only guide the cutting rope in a relatively single plane, making it difficult to meet the complex cutting requirements of ship lugs. In this design, the layout where the guide wheel shafts of the second guide wheel set 5 and the third guide wheel set 6 are perpendicular to each other constructs a precise three-dimensional cutting system. During the operation of the cutting rope 7, it can accurately reach the lugs at any position on the hull under the dual guidance in the Y direction and the Z direction, and perform cutting at the most suitable angle and tension. For example, when cutting a lug installed at an inclined angle on the top of a ship's cabin, the second guide wheel set 5 can guide the cutting rope 7 to adjust its position in the Y direction, and the third guide wheel set 6 guides the cutting rope 7 in the Z direction, ensuring that the cutting rope 7 can closely fit the contour of the lug for cutting, greatly improving the cutting accuracy and quality.

[0121] 2. Enhance the adaptability of the equipment to complex working conditions: The shipbuilding workshop environment is complex, with interference factors such as vibration and dust. At the same time, the lug designs and installation requirements for different ship projects are also different. The design where the guide wheel shafts of the second guide wheel set 5 and the third guide wheel set 6 are perpendicular to each other enables the equipment to better adapt to these complex working conditions. When facing vibration interference, the vertical guide wheel shaft structure can effectively disperse and buffer the vibration energy, ensuring the running stability of the cutting rope 7. For example, when large mechanical equipment in the workshop operates and generates vibration, the second guide wheel set 5 and the third guide wheel set 6 can decompose the vibration in different directions through their vertical structure design, reducing the impact of vibration on the cutting rope 7 and ensuring the continuity of the cutting operation. In addition, for the diverse lug cutting requirements in different ship projects, by adjusting the positions and angles of the second guide wheel set 5 and the third guide wheel set 6 and combining their vertical guiding characteristics, the equipment can quickly adapt to new cutting tasks.

[0122] 3. Optimize cutting efficiency and equipment reliability: During shipbuilding, improving cutting efficiency and ensuring equipment reliability are crucial for shortening the construction cycle and reducing costs. The layout where the guide wheel shafts of the second guide wheel group 5 and the third guide wheel group 6 are perpendicular to each other optimizes the running path and force-bearing situation of the cutting rope 7, thereby improving cutting efficiency. Under the precise guidance of the cutting rope 7 in two mutually perpendicular directions, it can run more smoothly, reducing energy loss and extended cutting time caused by poor guidance. At the same time, this stable guiding structure also enhances equipment reliability. The mutually perpendicular guide wheel shafts provide stable support for the cutting rope 7, reducing the shaking and deviation of the cutting rope 7 during operation and lowering the risk of equipment failure. For example, when continuously cutting lugs at multiple different positions and angles, the equipment can maintain an efficient and stable operating state to ensure the smooth progress of the cutting operation.

[0123] Optionally, the second guide wheel group 5 is located below the driving wheel group 3, and specifically, the number of them is, for example, 2.

[0124] Optionally, a connecting plate 8 is connected to the lower part of the frame 1, and the second guide wheel group 5 is assembled on the connecting plate 8 so that the second guide wheel group 5 is located below the driving wheel group 3.

[0125] Optionally, the connecting plate 8 is connected to the cross frame 1B so that each guide wheel shaft 51 in the second guide wheel group 5 is assembled on the cross frame 1B.

[0126] Optionally, the third guide wheel group 6 is located in front of the second guide wheel group 5, close to the object to be cut, and specifically, the number of them is, for example, 2.

[0127] Optionally, a third guide wheel group assembly seat 9 is connected to the lower part of the frame 1, and the third guide wheel group 6 is assembled on the third guide wheel group assembly seat 9 so that the third guide wheel group 6 is located in front of the second guide wheel group 5.

[0128] Optionally, the third guide wheel group assembly seat 9 is connected to the cross frame 1B so that each guide wheel shaft 61 in the third guide wheel group 6 is assembled on the cross frame 1B, and further, the third guide wheel group 6 is assembled on the cross frame 1B.

[0129] To this end, a connecting plate 8 is connected below the frame 1 of the lifting lug cutting wire saw machine of the present application. The second guide wheel set 5 is assembled below the driving wheel set 3 through the connecting plate 8, and the number is 2. At the same time, the connecting plate 8 is connected to the cross frame 1B, so that each guide wheel shaft 51 of the second guide wheel set 5 is stably assembled on the cross frame 1B. This design is not without basis. It is the result of a large amount of creative work by the R & D team after in-depth study of the actual operation space and cutting mechanics requirements in the shipbuilding workshop. At the shipbuilding site, the space is limited and there are many obstacles. Placing the second guide wheel set 5 below the driving wheel set 3 and connecting it to the cross frame 1B effectively utilizes the space below the equipment, avoids interference with other components, and at the same time provides a stable lower-side guide for the cutting wire 7, ensuring that the cutting wire maintains a stable tension and accurate trajectory during operation, greatly improving the cutting accuracy and efficiency.

[0130] During the actual cutting process, when cutting the lifting lugs at a lower position at the bottom of the hull, the unique position and guiding function of the second guide wheel set 5 are fully demonstrated. It can guide the cutting wire 7 to approach the lifting lug at an appropriate angle and tension, overcome the cutting difficulty caused by the lower position, and successfully complete the precise cutting of these lifting lugs. If the traditional guide wheel layout method is adopted, it is very difficult to achieve such precise cutting operations in a limited space.

[0131] In addition, a third guide wheel set assembly seat 9 is also connected below the frame 1. The third guide wheel set 6 is located in front of the second guide wheel set 5 through the assembly seat 9, close to the object to be cut, and the number is also 2. The third guide wheel set assembly seat 9 is also connected to the cross frame 1B, so that each guide wheel shaft 61 in the third guide wheel set 6 is assembled on the cross frame 1B, and then the third guide wheel set 6 is stably assembled on the cross frame 1B. This design is also carefully conceived for the complex distribution of lifting lugs in shipbuilding. In some structural parts of the ship, there are complex structural members around the lifting lugs, and it is difficult for traditional cutting equipment to approach and accurately cut. The design that the third guide wheel set 6 is located in front of the second guide wheel set 5 and close to the object to be cut enables the cutting wire 7 to more flexibly bypass obstacles and accurately reach the target lifting lug position. For example, when cutting the lifting lugs inside the ship's cabin, where there are many pipes and support structures around, the third guide wheel set 6 can guide the cutting wire 7 to cleverly avoid these obstacles and cut the lifting lugs from the best angle, greatly improving the adaptability of the equipment to complex working conditions.

[0132] In the entire shipbuilding project, the lifting lug cutting wire saw machine of the present application has efficiently completed the cutting tasks of a large number of lifting lugs with its unique guide wheel set layout design. Compared with the traditional cutting method, the cutting efficiency has increased several times, and the cutting accuracy also meets the strict requirements of shipbuilding, effectively shortening the shipbuilding cycle and reducing the production cost.

[0133] Preferably, a second sliding pair 16 is provided on the transverse frame 1B. The second sliding pair 16 includes a second slider 161 and a second guide rail 162. The second slider 161 is provided on the lower surface of the transverse frame 1B, and the second guide rail 162 is provided on a sliding plate 17, so that the second slider 161 and the second guide rail 162 are slidably connected. In addition, a traveling device 18 (including but not limited to wheels) is provided on the sliding plate 17. The traveling device 18 travels along the working surface on the hull under the drive of a traveling drive device 19 (such as a combination of a motor and a speed reducer), thereby driving the sliding plate 17 to slide, and further driving the second guide rail 162 relative to the second slider 161. Here, the second guide rail 162 slides while the second slider 161 remains stationary. In other cases, it can also be arranged that the second guide rail 162 is stationary while the second slider 161 slides.

[0134] Preferably, the third guide wheel set is connected to the sliding plate 17 (such as in the front), so that when the sliding plate 17 slides to drive the second guide rail 162 to slide relative to the second slider 161, the third guide wheel set also slides synchronously.

[0135] Preferably, the design of providing the second sliding pair 16 on the transverse frame 1B and connecting the third guide wheel set to the sliding plate 17 is not a conventional idea, but the result of a large amount of creative labor for specific scenarios in shipbuilding, and has significant technical advantages:

[0136] 1. Achieve flexible and precise adjustment of cutting positions: In shipbuilding, the positions of lugs are scattered and irregular, and it is difficult for traditional cutting equipment to respond flexibly. The design of the second sliding pair 16 enables the third guide wheel set to move precisely driven by the sliding plate 17. When facing lugs distributed in different areas of the hull, the traveling drive device 19 can drive the traveling device 18 to move the sliding plate 17 along the working surface of the hull according to the position of the lugs. For example, when cutting lugs located at the corners or in narrow spaces of the hull, by controlling the sliding of the sliding plate 17, the third guide wheel set can accurately guide the cutting rope 7 to the cutting position, ensuring that the cutting rope acts on the lug at the best angle and tension, greatly improving the cutting accuracy.

[0137] 2. Enhance the adaptability of the equipment to complex hull structures: Ship structures are complex and diverse, with many special-shaped parts and irregular working surfaces. The design of the second sliding pair 16 in cooperation with the traveling device 18 endows the equipment with the ability to move and operate on different hull structures. Whether it is on a flat deck area or the side of the hull with a certain curvature or slope, the equipment can adjust the position of the sliding plate 17 to adapt to changes in different working surfaces. For example, when cutting lugs on the bow part with a curved structure, the sliding plate 17 can move flexibly according to the shape of the hull curve, driving the third guide wheel set to adjust the direction of the cutting rope 7 to ensure the smooth progress of the cutting operation.

[0138] 3. Improve cutting efficiency and equipment automation: In the process of shipbuilding, it is crucial to improve cutting efficiency and automation. The sliding of the sliding plate 17 is controlled by the traveling drive device 19 composed of a motor and a speed reducer, realizing the automatic positioning of the third guide wheel set, and reducing the time and energy consumption of manually adjusting the equipment position. Compared with the traditional method of manually moving the equipment to different lug positions for cutting, this design can cut lugs at different positions quickly and continuously. For example, during the construction of large ship sections, the movement path of the sliding plate 17 can be planned at one time, and multiple lugs in this area can be cut automatically, greatly improving the cutting efficiency.

[0139] Preferably, when two third guide wheel sets are provided, which are respectively located in front of the cross frame 1B and arranged left and right, correspondingly, one third guide wheel set corresponds to one second sliding pair 16, one second sliding pair 16 corresponds to one traveling device 18, and one traveling device 18 corresponds to one traveling drive device 19, so that each second sliding pair 16 can act independently to drive the corresponding third guide wheel set to travel independently, and there is a stroke difference between the two third guide wheel sets, so that the cutting rope 7 is adjusted from the third movement direction perpendicular to the second movement direction and the first movement direction to an angle other than 90 degrees with the second movement direction, so as to facilitate adjusting the cutting direction of the cutting rope 7 for the lug.

[0140] Preferably, the lugs on the ship are widely distributed with different positions and angles, which requires the cutting equipment to have extremely high flexibility and accuracy. The design of setting two independently controllable third guide wheel sets, and each guide wheel set is equipped with a dedicated second sliding pair 16, traveling device 18 and traveling drive device 19 to realize flexible adjustment of the cutting direction of the cutting rope 7 has significant technical advantages in many aspects:

[0141] 1. Achieve accurate cutting at multiple angles: The installation angles of ship lugs are diverse. Traditional cutting equipment can often only cut within a limited angle range, making it difficult to meet the cutting requirements for lugs at different angles in shipbuilding. In this design, by controlling the two third guide wheel sets by independent drive systems respectively, a stroke difference can be generated, and then the movement direction of the cutting rope 7 can be adjusted from the conventional vertical direction to an angle other than 90 degrees with the second movement direction. For example, when encountering a lug inclinedly installed on the hull structure, by controlling the two traveling drive devices 19, the corresponding third guide wheel sets move according to different strokes, and the cutting rope 7 can cut in a direction matching the inclination angle of the lug, ensuring that the cutting surface is flat and meets the accuracy requirements.

[0142] 2. Adapt to complex ship structures: Ship structures are complex, with a large number of irregular parts and narrow spaces, and the lifting lugs may be distributed in these inaccessible places. The design of two independent third guide wheel sets enables the equipment to operate flexibly in complex ship structures. Inside the narrow cabin or at the hull corner, one of the third guide wheel sets can adjust its stroke to guide the cutting rope 7 around obstacles and reach the target lifting lug position for cutting. The other guide wheel set can remain relatively stable or make auxiliary position adjustments according to the actual situation to ensure that the cutting rope 7 always maintains an appropriate tension and cutting direction in the complex environment.

[0143] 3. Improve cutting efficiency and intelligence level: In the shipbuilding process, improving cutting efficiency and intelligence level is crucial for shortening the construction cycle and reducing costs. The independent drive system of each third guide wheel set enables the equipment to quickly plan and execute the cutting path according to the distribution of the lifting lugs. For example, when cutting multiple lifting lugs at different angles in an area, the equipment can pre-program or adjust the walking drive device 19 in real time to make the two third guide wheel sets work together to cut the lifting lugs in the most optimized order and angle, reducing the idling time and the number of position adjustments of the equipment and greatly improving the cutting efficiency.

[0144] Preferably, the lifting lug cutting wire saw machine further includes a cutting rope stabilizing module 20 for applying a stabilizing force to the cutting rope 7 when the cutting rope 7 cuts the lifting lug to stabilize the tension of the cutting rope 7 and thus ensure the cutting effect.

[0145] Preferably, the cutting rope stabilizing module 20 includes a first adsorption structure 21, a second adsorption structure 22, and a stabilizing rod 23. The first adsorption structure 21 and the second adsorption structure 22 are connected to both ends of the stabilizing rod 23 to be in an adsorption state (such as adsorbing to the hull) when the lifting lug cutting wire saw machine is working to form a touch pressure on the cutting rope 7, thereby generating a stabilizing force on the cutting rope 7. Considering that when the cutting rope 7 cuts the lifting lug, a cutting action occurs under the drive of the driving wheel set, therefore, the stabilizing rod 23 is designed as a bearing structure, which includes: a bearing string member 231 and a rotating outer sleeve 232. The bearing string member 231 is connected between the first adsorption structure 21 and the second adsorption structure 22, and the rotating outer sleeve 232 is sleeved on the bearing string member 231. The rotating outer sleeve 232 forms a touch pressure on the cutting rope 7. When the cutting rope 7 cuts the lifting lug, the rotating outer sleeve 232 rotates based on the bearing string member 231, avoiding abrasion of the cutting rope 7 and at the same time generating a stabilizing force on the cutting rope 7.

[0146] The above-mentioned first adsorption structure 21 and second adsorption structure 22 can be realized, for example, by an electromagnet or by a pressure suction method.

[0147] Preferably, in shipbuilding, where the operation environment is complex and there are interference factors such as vibration and swaying, it is very difficult for traditional cutting equipment to ensure that the cutting rope always maintains a stable tension and operating state during the cutting process. Therefore, based on the cutting rope stability module 20 of the above-mentioned lug cutting rope saw machine, it has significant technical advantages:

[0148] 1. Ensure cutting accuracy and quality: The cutting accuracy of ship lugs is directly related to the safety of the overall ship structure and the smooth progress of subsequent assembly work. During the cutting process, the cutting rope 7 is easily disturbed by various external forces, resulting in swaying or changes in tension, which leads to a decrease in cutting accuracy. The cutting rope stability module 20 adsorbs to the hull through the first adsorption structure 21 and the second adsorption structure 22, making the stabilizing rod 23 in a fixed state. The rotating outer sleeve 232 forms a stable contact pressure on the cutting rope 7. When the cutting rope 7 runs at high speed under the drive of the driving pulley set to cut the lug, the rotating outer sleeve 232 can effectively suppress the swaying of the cutting rope 7 and keep its tension stable, ensuring that the cutting rope 7 always cuts the lug accurately along the predetermined trajectory. For example, when cutting the lugs of key parts of a ship with high-precision requirements, the stability module can control the cutting error within a very small range, avoiding problems such as cutting deviation and lug deformation caused by the instability of the cutting rope, and greatly improving the cutting quality.

[0149] 2. Extend the service life of the cutting rope: As the key consumable of the lug cutting rope saw machine, the service life of the cutting rope directly affects the operation cost and production efficiency of the equipment. In traditional cutting operations, the cutting rope is easily worn and broken due to frequent exposure to unstable external forces, and needs to be replaced frequently. The design of the cutting rope stability module 20 effectively solves this problem. The stabilizing rod 23 adopts a bearing structure, and the rotating outer sleeve 232 is sleeved on the bearing string 231. When the cutting rope 7 runs, the rotating outer sleeve 232 can rotate flexibly based on the bearing string 231, forming a rolling friction with the cutting rope 7, greatly reducing the wear of the cutting rope 7. Compared with the traditional fixed contact pressure method, this design significantly extends the service life of the cutting rope 7. For example, when continuously performing a large number of lug cutting operations, after using the cutting rope stability module 20, the replacement frequency of the cutting rope 7 is greatly reduced, not only saving the consumable cost, but also reducing the equipment downtime caused by replacing the cutting rope, and improving the production efficiency.

[0150] 3. Adapt to complex ship operation environments: The environment in a ship manufacturing workshop is complex, with interference factors such as vibration and dust. At the same time, the ship structures are diverse, and the distribution positions and angles of the lifting lugs vary. The design of the cutting rope stabilizing module 20 fully considers these complex factors. The first adsorption structure 21 and the second adsorption structure 22 can firmly adsorb to the hull through electromagnetic magnets or pressure suction, etc., ensuring that the stabilizing module can work properly in various complex environments. Whether at a ship construction site with large vibrations or in an area with special lifting lug positions and limited space, the stabilizing module can provide a stable force for the cutting rope 7 through flexible adsorption methods and stable structural designs. For example, during the process of ship section construction, surrounding welding equipment, lifting equipment, etc. may generate strong vibrations. At this time, the stabilizing module can effectively buffer and absorb the vibration energy, ensuring the stable operation of the cutting rope 7.

[0151] Furthermore, a third adsorption device (not shown in the figure) is provided below the cross frame 1B so that when the lifting lug cutting rope saw machine is working, it is in an adsorbed state (such as adsorbed to the hull) through the third adsorption device, facilitating the operation of the lifting lug cutting rope saw machine.

[0152] Preferably, the lifting lug cutting rope saw machine further includes a gantry 22, which is bridged on the two second guide rails 162 on the left and right sides through two third sliders 163 and follows the sliding of the second guide rails 162 to prevent the stroke of the second guide rails 162 from becoming larger and the distance between the second guide rails 162 from becoming smaller, thereby causing the distance between the third guide wheel sets to become smaller and unable to form a tension on the cutting rope 7.

[0153] In the complex scenario of ship manufacturing, the lifting lug cutting operation has strict requirements for the coordinated operation and stability of each component of the equipment. The design of the gantry 22 bridged on the two second guide rails 162 through the third sliders 163 is by no means accidental. Instead, it is an ingenious solution obtained by the R & D team through a large amount of creative work in view of the operating characteristics of the equipment in ship manufacturing and has significant technical advantages:

[0154] 1. Ensure the stability of the cutting rope tension: When cutting the lifting lugs of a ship, the tension of the cutting rope 7 directly affects the cutting quality and efficiency. During the process of the second guide rails 162 having a larger stroke, if there is no effective constraint, the distance between the two second guide rails 162 is likely to become smaller, resulting in the reduction of the distance between the third guide wheel sets and being unable to maintain an appropriate tension for the cutting rope 7. The addition of the gantry 22 cleverly solves this problem. When the second guide rails 162 slide, the gantry 22 moves synchronously with the help of the third sliders 163 and uses its own structural rigidity to forcibly maintain the stability of the distance between the two second guide rails 162. For example, when cutting numerous lifting lugs on an extremely long ship section of the hull, the second guide rails 162 need to slide significantly to cover the lifting lugs at different positions. At this time, the gantry 22 can ensure that the distance between the third guide wheel sets remains constant, enabling the cutting rope 7 to always maintain the best tension state, ensuring a smooth cutting process, neat cut surfaces, and avoiding cutting deviations or jams caused by unstable tension.

[0155] 2. Improve the structural stability of the equipment: The environment in the shipbuilding workshop is complex, with interference factors such as vibration and collision, so the structural stability of the equipment is crucial. The gantry 22 straddles the second guide rails 162 on both sides, constructing a solid frame structure and enhancing the anti-interference ability of the entire equipment during operation. When large equipment in the workshop runs and generates vibration, the gantry 22 can evenly disperse the vibration energy, reducing the impact on the running stability of the third guide wheel set and the cutting rope 7. At the same time, during the movement of the equipment, the gantry 22 can prevent the second guide rail 162 from being distorted or deformed due to uneven force, ensuring the accuracy of the coordinated work of each component. For example, during the hoisting of ship sections, the surrounding environment may generate intense vibration, and the gantry 22 can effectively buffer the vibration, maintain the stability of the equipment, and ensure that the cutting operation is not affected.

[0156] 3. Enhance the adaptability and flexibility of the equipment: Shipbuilding processes are diverse, and there are differences in the distribution of lifting lugs and cutting requirements for different ship projects. The design of the gantry 22 enables the equipment to better adapt to these changes. When facing ship sections of different sizes or lifting lugs with different layouts, by adjusting the position of the gantry 22 on the second guide rail 162, the coverage range of the third guide wheel set can be flexibly changed to meet diverse cutting requirements. For example, when building small ships, the span of the gantry 22 can be appropriately shortened to improve the operation flexibility of the equipment in a narrow space; while when building large ships, the span of the gantry 22 can be increased to ensure that the equipment can cover a larger area of the lifting lug cutting area.

[0157] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
