Description

Technical Field

[0001] The invention relates to the technical field of ship assembly, and in particular to a device and method for turning over a pile leg on the ground. Background Art

[0002] The pile leg is a key component of a self-elevating drilling rig or platform, used to support the entire hull or platform to lift off the sea surface. The structure of the pile leg is generally cylindrical, which can provide good bearing capacity and stability. The length of a single cylindrical pile leg is about 40 to 70 meters, and the diameter is about 2 to 5 meters. According to the structural characteristics of the cylindrical pile leg, the cylindrical pile leg can only be laid in a horizontal position for assembly, painting, installation of outfitting parts, etc. After the pile leg operation is completed, the pile leg needs to be turned over 90 degrees for pile insertion and lifting. The main lifting code is set at the upper end of the pile leg, and the auxiliary lifting code is set at the lower end of the pile leg. The pile leg is turned over by the lifting code.

[0003] At present, the following deficiencies exist in the prior art during the turning over of the pile legs: 1. The lower end turning auxiliary hanging code is fixed on the outer surface of the cylindrical pile leg. Since the pile insertion accuracy needs to be controlled within 10 mm, the turning auxiliary hanging code needs to be removed and the code foot needs to be polished to ensure that it does not affect the pile insertion. However, it takes a lot of time to remove the hanging code and polish the code foot, which greatly affects the pile insertion efficiency; 2. The lower section turning auxiliary hanging code is set on the inner surface of the cylindrical pile leg. Although the steps of removal and polishing are avoided, during the turning over process, the pile leg cylinder is easy to scrape the wire rope, posing a safety hazard. This safety hazard may cause the wire rope to break, the pile leg to be damaged, or even cause more serious safety accidents. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in the prior art, during the turning operation of the cylindrical pile leg, the lower end turning auxiliary hanging code is mostly fixed on the outer surface or inner surface of the pile leg.

[0010] In one embodiment, the turning assembly further includes a third web, which is disposed at the other end of the clamping plate away from the limiting groove, and the third web extends in the vertical direction and penetrates the main plate body.

[0011] In one embodiment, the first and second ear plates are inclined in a direction away from the axis of the cylindrical pile leg, and the inclination arc of the first and second ear plates is the same as the inclination arc of the cylindrical pile leg.

[0036] In the description of the present invention, it should be understood that the terms "first" and "second" are used in the present invention for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0037] like Figures 1 to 7 As shown, an embodiment of the present invention preferably provides a pile leg landing turning device, which includes a plurality of turning components 1, and the turning component 1 includes a main board 11, a clamping plate 12, a first flange 13 and a second flange 14. The main board 11 extends in the horizontal direction, and one end of the main board 11 is provided with a through hole 111 for convenient transportation of the turning component 1, and the through hole 111 passes through the main board 11; the clamping plate 12 is connected to the end of the main board 11 away from the through hole 111, and the clamping plate 12 extends in the vertical direction; the first flange 13 and the second flange 14 are arranged at the end of the clamping plate 12 away from the main board 11, and the first flange 13 and the second flange 14 are arranged at intervals in the vertical direction, and the first flange 13, the second flange 14 and the clamping plate 12 are mutually enclosed to form a limiting groove for fixing the cylindrical pile leg 2, and the limiting groove is engaged with the cylindrical pile leg 2.

[0038] Based on the above technical features, the embodiment of the present invention is provided with a turning assembly 1, and the turning assembly 1 includes a main board 11, a card plate 12, a first flange 13 and a second flange 14. The main board 11 extends in the horizontal direction to provide a stable base for the entire turning assembly 1. A through hole 111 is provided at one end of the main board 11. This design not only reduces the weight of the entire assembly, but also facilitates operations during transportation and hoisting. The turning assembly 1 can be easily fixed and moved using a sling or other hoisting tools through the through hole 111; the card plate 12 is connected to the end of the main board 11 away from the through hole 111 to ensure the continuity and stability of the entire structure. The card plate 12 extends in the vertical direction to form a right angle or a nearly right angle structure with the main board 11, which is convenient for subsequent The first elbow plate 13 and the second elbow plate 14 provide support for installation; the first elbow plate 13 and the second elbow plate 14 are arranged at intervals in the vertical direction, and the first elbow plate 13 and the second elbow plate 14 together with the clamping plate 12 form a limiting groove, which can tightly fix the cylinder of the cylindrical pile leg 2 to prevent it from sliding or falling off during the turning process. The limiting groove is an important part of the entire turning device, which ensures the stability and safety of the cylindrical pile leg 2 during the turning process. At the same time, the limiting groove cooperates with the cylindrical pile leg 2 to be clamped, so that after the turning operation of the cylindrical pile leg 2 is completed, the turning assembly 1 can automatically fall off under the action of gravity, which effectively improves the pile insertion efficiency of the cylindrical pile leg 2 and eliminates the risk of the cylinder of the pile leg scraping and pressing the lifting wire rope.

[0039] Furthermore, the distance between two adjacent turning components 1 is 750 mm. The distance of 750 mm not only ensures that there is enough space between adjacent turning components 1 to avoid mutual interference during the turning process, but also ensures the compactness of the overall layout of the device and improves the space utilization rate. The reasonable spacing between adjacent turning components 1 helps to disperse the stress generated by the device during the turning process, thereby enhancing the stability of the overall structure. Too close spacing may lead to stress concentration, while too far spacing may reduce the overall rigidity of the device.

[0040] As some embodiments of the present invention, Figure 1 to Figure 2 As shown, the turning assembly 1 further includes a first web 15 and a second web 16, which are respectively arranged at the left and right ends of the main board 11, and the first web 15 and the second web 16 both extend in the vertical direction. The first web 15 and the second web 16 are respectively arranged at the left and right ends of the main board 11, and this layout enables the entire turning assembly 1 to be effectively supported and extended in the horizontal direction. Both extend in the vertical direction, forming a nearly vertical structure with the main board 11, thereby enhancing the stability and bearing capacity of the assembly in the vertical direction. The addition of the first web 15 and the second web 16 provides additional support for the main board 11, making the entire turning assembly 1 less likely to be deformed or damaged when subjected to external forces. This design helps to disperse the stress generated during the turning process, and improves the bending strength and torsional rigidity of the turning assembly 1.

[0041] As some embodiments of the present invention, Figure 1 to Figure 2 As shown, a first toggle plate 18 is arranged between the first web 15 and the first elbow plate 13, one end of the first toggle plate 18 is connected to the first web 15, and the other end is connected to the first elbow plate 13. The number of the first toggle plates 18 is at least two, and two adjacent first toggle plates 18 are arranged at intervals in the horizontal direction. The number of the first toggle plates 18 is at least two, which means that there are multiple supports between the first web 15 and the first elbow plate 13, which further improves the bearing capacity of the structure. The two adjacent first toggle plates 18 are arranged at intervals in the horizontal direction. This layout not only ensures the uniformity of the support, but also avoids the structural complexity and weight increase caused by the over-dense first toggle plates 18. At the same time, the addition of the first toggle plate 18 significantly improves the bending strength and torsional rigidity of the turning assembly 1 in the horizontal and vertical directions. During the turning process, the first toggle plate 18 can effectively disperse and withstand the stress generated, preventing the turning assembly 1 from being deformed or damaged due to excessive force.

[0042] As some embodiments of the present invention, Figure 1 to Figure 2As shown, a second toggle plate 19 is arranged between the second web 16 and the second elbow plate 14, one end of the second toggle plate 19 is connected to the second web 16, and the other end is connected to the second elbow plate 14. The number of the second toggle plates 19 is at least two, and two adjacent second toggle plates 19 are arranged at intervals in the horizontal direction. The second toggle plate 19 is arranged between the second web 16 and the second elbow plate 14, and plays a role of connection and support, and forms a symmetrical or similar structural layout with the first toggle plate 18. One end of the second toggle plate 19 is connected to the second web 16, and the other end is connected to the second elbow plate 14, which enhances the rigidity and stability of the entire turning assembly 1 on the other side. At the same time, the number of the second toggle plates 19 is at least two, ensuring that there are multiple supports between the second web 16 and the second elbow plate 14, and improving the bearing capacity of the structure. The design of the second toggle plate 19 is symmetrical with the first toggle plate 18, so that the entire turning assembly 1 is more balanced and stable in structure. This symmetry helps to disperse the stress generated during the turning process and prevent the assembly from being deformed or damaged due to uneven force.

[0043] As some embodiments of the present invention, Figure 1 to Figure 2 As shown, the turning assembly 1 also includes a third web 17, which is arranged at the other end of the cardboard 12 away from the limiting groove, the third web 17 extends in the vertical direction, and the third web 17 penetrates the main board 11. The third web 17 is arranged at the other end of the cardboard 12 away from the limiting groove, that is, the non-supporting end of the cardboard 12, and the third web 17 penetrates the main board 11, which means that the third web 17 is not only connected to the cardboard 12, but also forms a tight combination with the main board 11. This penetration design enhances the connection strength between the main board 11 and the cardboard 12, making the entire turning assembly 1 more stable and less prone to deformation when subjected to force. At the same time, the addition of the third web 17 provides an additional vertical support point for the turning assembly 1, enhances the bearing capacity and bending strength of the assembly in the vertical direction, and during the turning process, the third web 17 can effectively disperse and withstand the stress generated, preventing the turning assembly 1 from being damaged or failing due to excessive force.

[0044] As some embodiments of the present invention, Figure 1 to Figure 2As shown, the first yoke plate 13 and the second yoke plate 14 are tilted in the direction away from the axis of the cylindrical pile leg 2, and the first yoke plate 13 and the second yoke plate 14 are tilted at the same angle as the tilt of the cylindrical pile leg 2. The tilt design of the first yoke plate 13 and the second yoke plate 14 enables them to better fit the cylindrical edge of the cylindrical pile leg 2, ensuring the close contact between the device and the pile leg during the turning process. This fit not only improves the support and stability of the device on the pile leg, but also reduces the friction and wear caused by poor contact, thereby extending the service life of the device. The first yoke plate 13 and the second yoke plate 14 have the same tilt of the arc as the arc of the pile leg, which means that during the turning process, the yoke plate can evenly distribute and bear the stress generated by the pile leg, avoiding the occurrence of stress concentration. This design helps to optimize the mechanical properties of the device and improve its stability and bearing capacity under stress.

[0045] As some embodiments of the present invention, Figure 1 to Figure 2 As shown, the connection between the third web 17 and the first elbow plate 13 is provided with an inclined first chamfer 121, and the first chamfer 121 is used to reinforce the first elbow plate 13; the connection between the third web 17 and the second elbow plate 14 is provided with an inclined second chamfer 122, and the second elbow plate 14 is used to reinforce the second elbow plate 14. The first chamfer 121 is inclined, coordinated with the inclined direction of the first elbow plate 13, forming a smooth transition structure, which helps to disperse and withstand the stress generated by the first elbow plate 13 during the turning process, and prevents the deformation or damage of the elbow plate caused by stress concentration. At the same time, the first chamfer 121 also increases the contact area between the third web 17 and the first elbow plate 13, and improves the connection strength and stability between them. The design of the second chamfer 122 is similar to that of the first chamfer 121, and is also inclined to coordinate with the inclined direction of the second elbow plate 14. It also plays the role of dispersing and bearing stress, preventing the second elbow plate 14 from being deformed or damaged when subjected to stress. The second chamfer 122 also increases the contact area between the third web 17 and the second elbow plate 14, thereby enhancing the connection strength and stability therebetween.

[0046] As some embodiments of the present invention, Figure 1 to Figure 2 As shown, the end of the main board 11 away from the limiting groove is rounded to improve the stability of the main board 11 in contact with the ground after flipping. The round end surface can more effectively disperse the pressure when the main board 11 contacts the ground, avoiding deformation of the main board 11 due to pressure concentration. This pressure dispersion effect helps to protect the ground and the main board 11 and prolong the service life of the device.

[0047] Furthermore, all components in the turning assembly 1 are fixed by welding. It is an effective design choice that all components in the turning assembly 1 are fixed by welding. It not only improves the structural strength, stability and durability of the device, but also enhances the bearing capacity and safety of the device. At the same time, welding fixation also has the advantages of simple manufacturing process, low cost and convenient maintenance. This design makes the pile leg ground turning device more reliable, efficient and durable in practical applications, and can meet various complex and changeable work requirements.

[0048] As some embodiments of the present invention, Figure 4 As shown, the pile leg ground turning device also includes a channel steel member 3, which is arranged between two adjacent turning assemblies 1, one end of the channel steel member 3 is connected to one of the turning assemblies 1, and the other end is connected to the other turning assembly 1. The channel steel member 3 is arranged between two adjacent turning assemblies 1, and plays a bridge-like connecting role, closely connecting each independent turning assembly 1 to form an integral structure. Through the connection of the channel steel member 3, the relative position between adjacent turning assemblies 1 is fixed, effectively preventing relative movement or dislocation due to external force during use, thereby enhancing the overall stability of the device.

[0049] As some embodiments of the present invention, Figures 5 to 7 As shown, the present invention also provides a pile leg landing turning method, which is applicable to the above pile leg landing turning device, and comprises the following steps:

[0050] Step S1, transport the pile legs in a lying state to the construction site, and hang the crane wire rope on the hanging code at the front end of the pile legs; during transportation, ensure that the pile legs are stable and not damaged, and may need to be reinforced with a support frame or a fixing belt. At the construction site, check the status of the crane to ensure that the crane can work normally and meet safety standards, select a suitable wire rope, ensure that its carrying capacity matches the weight of the pile legs, and that the wire rope has no safety hazards such as wear and breakage, find the hanging code at the front end of the pile leg, which is a connection point specially designed for lifting, and correctly hang the crane wire rope on the hanging code to ensure that the connection is firm and will not slip. When hanging the wire rope, follow the safety operating procedures to ensure that the operator will not be injured.

[0051] Step S2, after the hanging of the lifting code is completed, transport at least two turning components 1 to the lower end of the rear end of the pile leg, and insert the pile leg into the limiting groove, and temporarily fix at least two turning components 1 by the channel steel; confirm that the lifting code has been firmly hung on the lifting code at the front end of the pile leg, and the crane wire rope is ready, and the lifting operation can be carried out at any time, check the status of the pile leg to ensure that it is not damaged or deformed, and lies flat and stable, transport the turning component 1 to the lower end of the rear end of the pile leg, align the limiting groove of the turning component 1 with the lower end of the rear end of the pile leg, slowly insert the tube edge of the pile leg into the limiting groove, use the channel steel part 3 as a temporary fixing part, and connect at least two turning components 1 together.

[0052] Step S3, after the installation of the turning assembly 1 is completed, the crane is used to lift the hanging code in the vertical direction, the pile legs are converted from a flat state to a vertical state, and the turning assembly 1 at the lower end of the pile legs contacts the ground; start the crane, slowly lift the hanging code in the vertical direction, during the hoisting process, the crane should be kept stable, and sudden acceleration or deceleration should be avoided to cause the pile legs to shake. The operator should pay close attention to the state of the pile legs to ensure that they are raised steadily without tilting or twisting. With the lifting of the crane, the pile legs are gradually converted from a flat state to a vertical state. In this process, the turning assembly 1 plays a supporting and guiding role to ensure that the pile legs can be turned over smoothly. It is necessary to pay attention to the speed and strength of controlling the turning of the pile legs to avoid excessive or violent turning to cause damage to the pile legs or the turning assembly 1. When the pile legs are completely turned over to a vertical state, the turning assembly 1 at the lower end of the pile legs should contact the ground.

[0053] Step S4, the crane continues to lift the lifting weight in the vertical direction, and after the turning assembly 1 at the lower tube edge of the rear end of the pile leg is away from the ground, the turning assembly 1 falls off from the tube edge of the lower end of the pile leg under the action of gravity; after the pile leg has been stably in a vertical state and the turning assembly 1 at the lower tube edge of the rear end has a certain contact with the ground, the crane operator should continue to lift the lifting weight slowly and steadily in the vertical direction, observe the state of the turning assembly 1 and the lower tube edge of the rear end of the pile leg, and when the crane lifts the pile leg to a sufficient height so that the turning assembly 1 at the lower tube edge of the rear end of the pile leg is away from the ground, stop the lifting action of the crane, at this time, under the action of gravity, the turning assembly 1 completely falls off from the tube edge of the lower end of the pile leg and falls back to the ground safely, ensuring that the pile leg will not be affected or damaged due to the falling of the turning assembly 1, so as to complete the entire pile leg landing and turning operation.

[0054] In summary, the embodiment of the present invention provides a pile leg landing turning device and method, which has the following beneficial effects compared with the prior art: the main board 11 extends in the horizontal direction to provide a stable base for the entire turning assembly 1, and a through hole 111 is provided at one end of the main board 11. This design not only reduces the weight of the entire assembly, but also facilitates the operation during transportation and hoisting. The turning assembly 1 can be easily fixed and moved using a sling or other hoisting tools through the through hole 111; the card plate 12 is connected to the end of the main board 11 away from the through hole 111 to ensure the continuity and stability of the entire structure; the card plate 12 extends in the vertical direction to form a right angle or a nearly right angle structure with the main board 11, which is a first plate 13 and a second plate 13 for subsequent The second elbow plate 14 is installed to provide support; the first elbow plate 13 and the second elbow plate 14 are spaced apart in the vertical direction, and the first elbow plate 13 and the second elbow plate 14 together with the clamping plate 12 form a limit groove, which can tightly fix the cylinder of the cylindrical pile leg 2 to prevent it from sliding or falling off during the turning process. The limit groove is an important part of the entire turning device, which ensures the stability and safety of the cylindrical pile leg 2 during the turning process. At the same time, the limit groove cooperates with the cylindrical pile leg 2 to be clamped, so that after the turning operation of the cylindrical pile leg 2 is completed, the turning assembly 1 can automatically fall off under the action of gravity, which effectively improves the pile insertion efficiency of the cylindrical pile leg 2 and eliminates the risk of the cylinder of the pile leg scraping and pressing the lifting wire rope.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
