Description

Technical Field

[0001] This application relates to the field of pipe pile hoisting technology, and in particular to a hoisting beam for turning over steel pipe piles. Background Technology

[0002] In the preparation stage before the installation of wind turbine monopile foundations, the turning of steel pipe piles is a crucial step. Traditionally, this operation relies on the coordinated operation of two cranes, usually with the help of auxiliary cranes on floating crane vessels or transport vessels, or with the cooperation of other crane vessels.

[0003] In the existing technology, there are problems such as high equipment requirements, high construction costs, low efficiency, poor adaptability to dynamic environment and insufficient safety in the process of turning over and installing wind turbine monopile foundations. In particular, when two cranes work together, the high synchronization requirements increase the construction difficulty and risk. Moreover, the flexibility and versatility of existing equipment are limited, making it difficult to meet the high-efficiency operation requirements of steel pipe piles of different sizes. Utility Model Content

[0004] To address the high demand for equipment for turning over steel pipe piles, this application provides a lifting beam for turning over steel pipe piles.

[0005] The technical solution for a lifting beam used for turning over steel pipe piles provided in this application is as follows:

[0006] A lifting beam for turning over steel pipe piles includes a lifting beam body arranged above the steel pipe pile. The bottom of the lifting beam body is provided with two lower wire rope loops. Lifting lugs for cooperating with the lower wire rope loops are respectively provided on both sides of the steel pipe pile. A tail wire rope loop is provided on one side of the lifting beam body. A C-shaped tail clamp for docking with the tail of the steel pipe pile is provided on the tail wire rope loop. A winding and unwinding mechanism for winding and unwinding the tail wire rope loop is provided on the lifting beam body. A lifting mechanism for cooperating with a crane is provided on the top of the lifting beam body.

[0007] Due to the high equipment requirements, high construction costs, low efficiency, poor adaptability to dynamic environments, and insufficient safety during the overturning and installation of wind turbine monopile foundations, especially when two cranes work together, the high synchronization requirements increase the construction difficulty and risk. Moreover, the flexibility and versatility of existing equipment are limited, making it difficult to meet the high-efficiency operation requirements of steel pipe piles of different sizes. By adopting the above-mentioned technical solution, including the lifting beam body, the bottom of the lifting beam body is connected to the lifting lugs on both sides of the steel pipe pile through two lower wire rope loops, and one side of the lifting beam body is connected to the steel pipe pile through the tail C-shaped tail clamp of the tail wire rope loop, and the lifting and lowering are achieved through the retraction and lowering mechanism.

[0008] When hoisting and turning the steel pipe pile, start the crane of the floating crane vessel and slowly lower the lifting beam body to above the steel pipe pile. First, precisely connect the opening of the C-shaped tailing clamp on the tail wire rope loop with the tail of the steel pipe pile to complete the installation of the tailing sling. After the installation is completed, rotate the boom so that the lower wire rope loop of the lifting beam is aligned with the lifting lugs on both sides of the steel pipe pile. Connect the lower wire rope loop to the lifting lugs. After confirming that all connections are safe and reliable, slowly raise the lifting beam to a certain height. At the same time, the launching mechanism begins to gradually release the tail wire rope loop, so that the steel pipe pile smoothly transitions from a horizontal state to a vertical state, completing the steel pipe pile turning operation.

[0009] The design incorporates a lower wire rope loop, lifting lugs, a tail wire rope loop, and a C-shaped tail clamp, facilitating efficient turning of steel pipe piles. This simplifies the turning process and improves operational efficiency. The lifting beam can flexibly adapt to steel pipe piles of different sizes and specifications, greatly enhancing its versatility and practicality. It ensures the safety and stability of the entire operation, effectively reducing potential swaying or tilting of the steel pipe piles during turning, thereby lowering construction risks. Compared to the traditional method of coordinating two cranes, this lifting beam design allows for the turning of steel pipe piles with a single crane, reducing equipment requirements and construction costs. It also features a compact structure that is easy to operate and maintain.

[0010] Optionally, the hoisting mechanism includes two lifting rings and two upper wire rope loops. The two lifting rings are symmetrically arranged along the length of the hoisting beam body, and the two upper wire rope loops are respectively connected to the corresponding lifting rings.

[0011] By adopting the above technical solution, the hoisting mechanism includes two lifting rings and two upper wire rope loops. The symmetrical arrangement of the two lifting rings and upper wire rope loops helps to distribute the pressure during the hoisting process, making the force borne by each lifting point more even, which helps to enhance the load-bearing capacity of the lifting beam, making the lifting beam body more stable during the hoisting process, and improving the overall safety of the operation.

[0012] Optionally, stiffening plates are provided between the lifting beam body and the corresponding lifting ring to enhance structural strength, and the number of stiffening plates at the connection between the lifting beam body and the corresponding lifting ring is multiple.

[0013] By adopting the above technical solution, the stiffening plates are welded and fixed between the lifting beam body and the corresponding lifting ring; through the setting of the stiffening plates, the stiffening plates, as structural reinforcements, effectively disperse the concentrated stress during the lifting process and improve the load-bearing capacity of the lifting beam.

[0014] Optionally, the bottom of the lifting beam body is provided with a pin seat for installing the lower wire rope ring, and a rotating pin is rotatably provided on the pin seat, and the lower wire rope ring is arranged on the rotating pin.

[0015] By adopting the above technical solution, the pin seat is installed at the bottom of the lifting beam body, and the lower wire rope loop is installed on the rotating pin of the pin seat; through the setting of the pin seat and the rotating pin, the lifting beam can better adapt to steel pipe piles of different shapes and sizes, thereby improving the adaptability and efficiency of the operation.

[0016] Optionally, each of the lifting lugs is provided with a wing for winding a steel wire rope, and the wing and the overall cross-section of the lifting lug are T-shaped.

[0017] By adopting the above technical solution, the wing is integrally formed on the lifting lug; the setting of the wing increases the contact area between the wire rope and the lifting lug, thereby improving the stability of the connection and helping to ensure that the wire rope will not slip off or loosen from the lifting lug during the lifting process, thus ensuring the safety of the operation.

[0018] Optionally, the take-up and release mechanism includes a take-up and release seat, a take-up and release pin, and a take-up and release motor. The take-up and release seat is connected to one side of the lifting beam body, the take-up and release pin is rotatably connected inside the take-up and release seat, the output end of the take-up and release motor is connected to the take-up and release pin, and the tail wire rope loop is arranged on the take-up and release pin.

[0019] By adopting the above technical solution, the take-up and release mechanism includes a take-up and release base, a take-up and release pin, and a take-up and release motor. When taking up or releasing the tail wire rope loop, firstly, the take-up and release motor is started, driving the take-up and release pin to rotate within the take-up and release base. Since the tail wire rope loop is arranged on the take-up and release pin, the tail wire rope loop will be gradually released as the take-up and release pin rotates. As the tail wire rope loop is gradually released, the steel pipe pile will gradually transition from a horizontal state to a vertical state. The operator needs to adjust the speed and direction of the take-up and release motor in a timely manner according to the turning progress of the steel pipe pile to ensure that the release speed of the tail wire rope loop matches the turning speed of the steel pipe pile. Until the steel pipe pile is completely turned to a vertical state, the wire rope loop should maintain a certain tension to complete the operation. Through the setting of the take-up and release mechanism, the machine can accurately control the turning process, ensuring a smooth transition of the steel pipe pile from a horizontal state to a vertical state, avoiding swaying or tilting caused by speed mismatch, and improving the safety and stability of the operation.

[0020] Optionally, the take-up and release base is provided with a guide pulley assembly for guiding the wire rope, and the guide pulley assembly is rotatably arranged on the take-up and release base.

[0021] By adopting the above technical solution, the guide pulley block is installed on the take-up and release seat. The setting of the guide pulley block improves the motion state of the wire rope, avoids the wire rope from becoming disordered and tangled during the take-up and release process, helps to reduce the wear and damage of the wire rope, extends its service life, improves the take-up and release accuracy, and ensures the safety of the operation.

[0022] Optionally, the base plate of the retractable seat is provided with connecting bolts for connecting to the lifting beam body, and the number of connecting bolts is multiple sets.

[0023] By adopting the above technical solution, the retractable seat is installed on the lifting beam body by connecting bolts. The connection between the retractable seat and the lifting beam body is ensured by the setting of connecting bolts, which helps to prevent the connection from loosening or falling off due to vibration or impact during the hoisting process, improves the safety of the operation, and facilitates installation and disassembly.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] The design incorporates a lower wire rope loop, lifting lugs, a tail wire rope loop, and a C-shaped tail clamp, facilitating efficient turning operations for steel pipe piles. This simplifies the turning process and improves operational efficiency. The lifting beam can flexibly adapt to steel pipe piles of different sizes and specifications, greatly enhancing its versatility and practicality. It ensures the safety and stability of the entire operation, effectively reducing the swaying or tilting of the steel pipe piles during the turning process, thereby lowering construction risks. Compared to the traditional method of coordinating two cranes, this lifting beam design allows for the turning operation of steel pipe piles to be completed with a single crane, reducing equipment requirements and construction costs. It also features a compact structure that is easy to operate and maintain.

[0026] The symmetrical arrangement of the two lifting rings and the upper wire rope loops in the hoisting mechanism helps to distribute the pressure during the hoisting process, making the force borne by each lifting point more even, which helps to enhance the load-bearing capacity of the hoisting beam, making the hoisting beam body more stable during the hoisting process, and improving the overall safety of the operation.

[0027] With the addition and retraction mechanism, the machine can precisely control the turning process, ensuring a smooth transition of the steel pipe pile from a horizontal to a vertical state, avoiding swaying or tilting caused by speed mismatch, and improving the safety and stability of the operation.

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0033] This application discloses a lifting beam for turning over steel pipe piles. (Refer to...) Figure 1 The lifting beam used for turning over steel pipe piles includes a lifting beam body 1, which is located directly above the steel pipe pile 2. In this embodiment, a lifting mechanism 8 is installed on the top of the lifting beam body 1. The lifting mechanism 8 is used to cooperate with the crane of the floating crane vessel.

[0034] Reference Figure 1 The lifting mechanism 8 includes two lifting rings 81 and two upper wire rope loops 82. The two lifting rings 81 are welded and fixed to the top of the lifting beam body 1, and the two lifting rings 81 are symmetrically installed along the length of the lifting beam body 1. The two upper wire rope loops 82 correspond to the two lifting rings 81 respectively. The upper wire rope loops 82 are installed on the crane of the floating crane vessel, and one end of the upper wire rope loop 82 is sleeved and fixed on the corresponding lifting ring 81. The symmetrical arrangement of the two lifting rings 81 and the upper wire rope loops 82 helps to distribute the pressure during the lifting process, making the force borne by each lifting point more even, which helps to enhance the load-bearing capacity of the lifting beam, making the lifting beam body 1 more stable during the lifting process, and improving the overall safety of the operation.

[0035] Reference Figure 1 Each lifting ring 81 is welded and fixed to the lifting beam body 1 with a stiffening plate 9. There are multiple stiffening plates 9 at the connection between the lifting beam body 1 and the corresponding lifting ring 81. As a structural reinforcement, the stiffening plate 9 effectively disperses the concentrated stress during the lifting process and improves the load-bearing capacity of the lifting beam.

[0036] Reference Figure 1 Two pin seats 10 are installed at the bottom of the lifting beam body 1. The two pin seats 10 are symmetrically installed along the length of the lifting beam body 1. Each pin seat 10 has a rotating pin 11 that rotates through a bearing. A lower wire rope loop 3 is installed on the rotating pin 11 of the pin seat 10. At the same time, lifting lugs 4 are welded and fixed on both sides of the steel pipe pile 2. The two lifting lugs 4 correspond one-to-one with the lower wire rope loops 3 on the two pin seats 10. One end of the lower wire rope loop 3 is wrapped and fixed on the corresponding lifting lug 4.

[0037] Reference Figure 1 and Figure 2Meanwhile, each lifting lug 4 is integrally formed with a wing 41. In this embodiment, the overall cross-section of the wing 41 and the lifting lug 4 is T-shaped, which increases the contact area between the wire rope and the lifting lug 4, thereby improving the stability of the connection and helping to ensure that the wire rope will not slip off or loosen from the lifting lug 4 during the lifting process, thus ensuring the safety of the operation.

[0038] Reference Figure 1 and Figure 3 A retraction mechanism 7 is installed on one side of the lifting beam body 1. The retraction mechanism 7 includes a retraction seat 71, a retraction pin 72, and a retraction motor 73. The retraction seat 71 is connected to one side of the lifting beam body 1. Connecting bolts 13 are installed on the bottom plate of the retraction seat 71. In this embodiment, there are multiple sets of connecting bolts 13. The connecting bolts 13 ensure a stable connection between the retraction seat 71 and the lifting beam body 1, which helps to prevent the connection from loosening or falling off due to vibration or impact during the hoisting process, improves the safety of the operation, and facilitates installation and disassembly.

[0039] Reference Figure 3 The take-up and release pin 72 is rotatably mounted in the take-up and release base 71 via bearings. The take-up and release motor 73 is mounted on the take-up and release base 71. In this embodiment, the output end of the take-up and release motor 73 is connected to the end of the take-up and release pin 72. The take-up and release motor 73 can achieve forward and reverse rotation. A tail wire rope loop 5 is installed on the take-up and release pin 72. At the same time, a C-type tailing clamp 6 is installed on the tail wire rope loop 5. An interface for docking with the C-type tailing clamp 6 can be installed at the tail of the steel pipe pile 2.

[0040] Reference Figure 3 The guide pulley group 12 is also rotatably installed inside the take-up and release seat 71. The guide pulley group 12 is used to improve the motion state of the wire rope, avoid the wire rope from becoming disordered and tangled during the take-up and release process, help reduce the wear and damage of the wire rope, extend its service life, improve the take-up and release accuracy, and ensure the safety of the operation.

[0041] The implementation principle of a lifting beam for turning over steel pipe piles in this application embodiment is as follows: When turning over steel pipe pile 2, the crane of the floating crane vessel is started and the lifting beam body 1 is slowly lowered to above the steel pipe pile 2. First, the opening of the C-shaped tailing clamp 6 on the tail wire rope loop 5 is precisely engaged with the tail of the steel pipe pile 2 to complete the installation of the tailing sling. After the installation is completed, the boom is rotated so that the lower wire rope loop 3 of the lifting beam is aligned with the lifting lugs 4 on both sides of the steel pipe pile 2. The lower wire rope loop 3 is connected to the lifting lugs 4. After confirming that all connections are safe and reliable, the lifting beam is slowly raised to a certain height. At the same time, the retraction mechanism 7 begins to gradually release the tail wire rope loop 5, so that the steel pipe pile 2 smoothly transitions from a horizontal state to a vertical state, completing the turning over operation of the steel pipe pile 2.

[0042] The design incorporates a lower wire rope loop 3, lifting lugs 4, a tail wire rope loop 5, and a C-shaped tail clamp 6, facilitating efficient turning of the steel pipe pile 2. This not only simplifies the turning process but also improves operational efficiency. The lifting beam can flexibly adapt to steel pipe piles 2 of different sizes and specifications, greatly enhancing its versatility and practicality. It ensures the safety and stability of the entire operation, effectively reducing the swaying or tilting that may occur during the turning of the steel pipe pile 2, thereby reducing construction risks. Compared to the traditional method of coordinating two cranes, this lifting beam design allows for the turning of the steel pipe pile 2 to be completed with a single crane, reducing equipment requirements and construction costs. It also features a compact structure that is easy to operate and maintain.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
