Description
Technical Field
[0001] This utility model belongs to the field of steel strand technology, and specifically relates to a steel strand fastening device for towing and loading steel strands onto offshore oil platform structures. Background Technology
[0002] With the rapid development of China's offshore oil industry, the weight of individual offshore oil platform structures is increasing, leading to a greater number of steel strands required for towing and loading. Traditionally, mechanical methods are used for laying steel strands, typically employing anchor clamps and self-locking devices to connect the strands to the wire rope. However, both methods have several drawbacks, limiting efficiency, safety, and economy. While anchor clamps meet basic connection requirements to some extent, their main disadvantages are as follows: First, each strand requires three anchor clamps, a time-consuming, labor-intensive, and inefficient process. Second, anchor clamps may not be securely fastened, increasing construction risks and potentially causing strand slippage and personal injury. Third, tightening a single anchor clamp takes an average of 3-5 minutes, adding extra pressure to the loading schedule and increasing costs. Finally, the increased weight of individual modules leads to a greater number of steel strands required, further intensifying the workload. Furthermore, anchor clamps cannot effectively eliminate the torque generated by the coiling of steel strands during transportation, which may cause confusion during laying and affect the laying effect. On the other hand, using steel strand self-locking devices to connect steel strands also faces challenges: each steel strand self-locking device can only connect one steel strand, which means that when multiple steel strands need to be handled simultaneously, the work efficiency is extremely low; the operation is complicated, increasing the time cost of worker training and actual operation; similarly, steel strand self-locking devices cannot solve the problem of torque caused by the coiling of steel strands, which may lead to instability and potential safety hazards during the laying process. In summary, existing steel strand connection methods show obvious limitations in the face of the increasing demands of marine engineering. In order to solve the above problems and improve the efficiency, safety and economy of steel strand laying, it is necessary to develop a new type of steel strand fastening device to overcome the shortcomings of existing technologies. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an innovative and efficient steel strand fastening device to address several key problems existing in the existing steel strand laying technology.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a steel strand fastening device for towing and loading offshore oil platform structures, comprising: a shell, wherein the shell has a through hole, the shell has a main body and a base, the main body is fixed to one end of the base, and the through hole penetrates the main body and the base;

The entire process is quick and easy, greatly improving work efficiency and reducing labor and time costs. Simultaneously, it employs a shaft thrust self-rotator, which automatically eliminates the torque caused by the coiling of the steel strand during transportation as it transitions from a coiled to a straightened state. This design ensures that the steel strand will not become tangled or twisted due to torque during laying, thereby improving the quality and safety of the laying process.

[0021] The reference numerals are as follows: 100 outer shell, 110 through hole, 120 main body, 130 base, 200 fastening thread device, 300 steel strand locker, 400 elastic element, 500 shaft thrust spinner. Detailed Implementation
[0022] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 2This utility model provides a steel strand fastening device for towing and loading structures onto offshore oil platforms, comprising: a housing 100, a fastening threaded device 200, a steel strand locker 300, an elastic element 400, and a shaft thrust spinner 500. The housing 100 has a through hole 110 inside, and a main body 120 and a base 130 on the housing 100. The main body 120 is fixed to one end of the base 130, and the through hole 110 penetrates both the main body 120 and the base 130. The first end of the fastening threaded device 200 is engaged within the base 130, and the second end of the fastening threaded device 200 protrudes outside the housing 100. The steel strand locker 300 can pass through the through hole 110 and is fixed within the main body 120, with its first end engaged within the through hole. Inside the housing 110, the second end of the steel strand locking device 300 protrudes from the front end of the main body 120; the elastic element 400 is located between the first end of the steel strand locking device 300 and the first end of the fastening thread device 200. When the fastening thread device 200 is tightened, the elastic element 400 is compressed to push the steel strand locking device 300 into the main body, so that the second end of the steel strand locking device 300 clamps the steel strand; the shaft thrust spinner 500 is engaged at the end of the base 130 to automatically eliminate the torque of the steel strand. Through the combination of the housing 100, the fastening thread device 200, the elastic element 400 and the steel strand locking device 300, this utility model greatly simplifies the connection process between the steel strand and the transmission device. The installer simply threads the steel strand through the device and tightens the fastening thread 200 to complete the connection. The entire process is quick and easy, greatly improving work efficiency and reducing labor and time costs. Simultaneously, a shaft thrust spinner 500 is employed. This component automatically eliminates the torque caused by the coiling of the steel strand during transportation as it transitions from a coiled to a straightened state. This design ensures that the steel strand will not become tangled or twisted due to torque during laying, thereby improving the quality and safety of the installation.
[0023] Furthermore, through the coordinated operation of the housing 100, the fastening threaded device 200, the steel strand locking device 300, the elastic element 400, and the axial thrust spinner 500, the steel strand is securely clamped and torque is automatically eliminated during laying. This design not only improves the quality and efficiency of steel strand laying but also significantly enhances construction safety. Furthermore, by engaging the first end of the fastening threaded device 200 within the base 130 and allowing its second end to protrude from the housing 100, the user can adjust the pressure of the elastic element 400 by rotating the fastening threaded device 200. When the fastening threaded device 200 is tightened, the elastic element 400 is compressed, pushing the steel strand locking device 300 inwards, thereby clamping the steel strand. This design ensures that the steel strand will not slip under high tension, providing a reliable fixing effect. The axial thrust spinner 500, engaged at the end of the base 130, can automatically sense and release the torque of the steel strand during laying. This design effectively prevents the steel strands from tangling or becoming tangled due to curling, ensuring that multiple steel strands do not interfere with each other when laid simultaneously, thus improving the orderliness and consistency of the laying process. Because the torque of the steel strands is effectively eliminated, construction workers do not need to manually handle the curling of the steel strands during operation, reducing the probability of accidents and ensuring worker safety. Furthermore, the clamping force of the steel strand locking device 300 increases with the increase of tension, further enhancing the safety of the device.
[0024] Furthermore, this utility model does not limit the structure and shape of the main body 120. Preferably, the main body 120 is conical in shape, and the diameter of the main body 120 gradually decreases from the bottom to the top. (See reference...) Figure 1 The conical design allows the steel strand locking device 300 to fit more tightly against the inner wall of the through hole 110 when pushed by the elastic element 400. As the steel strand locking device 300 moves further into the main body, the friction between it and the through hole 110 gradually increases, thereby enhancing the clamping effect. This design is particularly suitable for laying steel strands under high tension conditions, ensuring that the steel strands will not slip or loosen. The conical design of the main body 120 helps to disperse the stress of the steel strand locking device 300 during the clamping process, avoiding the problem of excessive local stress. This not only extends the service life of the steel strand locking device 300, but also reduces the risk of failure during long-term use. The conical design allows the steel strand locking device 300 to be more accurately aligned with the through hole 110 during installation, reducing installation errors. This design is particularly suitable for applications requiring precise control of clamping force, ensuring that each steel strand receives uniform clamping force and improving the quality of laying.
[0025] Furthermore, the diameter of the base 130 is larger than the diameter of the main body 120. The larger diameter of the base 130 provides a wider support surface for the entire device, making the device more stable during installation and use. Especially under high tensile conditions, the base 130 can withstand greater external forces, ensuring that the device will not deform or be damaged due to uneven stress. At the same time, the larger diameter design of the base 130 increases the overall rigidity of the device, effectively resisting external impact forces. Furthermore, this utility model does not limit the specific shape of the steel strand locking device 300. Preferably, the outer surface of the steel strand locking device 300 is wedge-shaped. The wedge-shaped design allows the steel strand locking device 300 to generate a greater clamping force through the wedge effect when subjected to the thrust of the elastic element 400. As the steel strand locking device 300 moves into the main body, the contact area between the wedge-shaped surface and the inner wall of the through hole 110 gradually increases, and the frictional force also increases, thereby enhancing the clamping effect. This design is particularly suitable for laying steel strands under high tension conditions, ensuring that the steel strands will not slip or loosen. Simultaneously, the wedge-shaped design allows the clamping force of the steel strand locking device 300 to automatically increase with increasing tension. This self-locking effect ensures that the steel strands maintain a stable clamping state even under high tension, preventing slippage due to excessive tension. Furthermore, the wedge-shaped design reduces direct contact between the steel strand locking device 300 and the inner wall of the through hole 110, lowering the friction between them. This not only extends the service life of the steel strand locking device 300 but also reduces the risk of wear and tear during long-term use.
[0026] Furthermore, this utility model does not limit the specific structure of the steel strand locking device 300. Preferably, referring to... Figure 2 The steel strand locking device 300 consists of multiple relatively movable clamping plates. This design allows the device to automatically adjust the position of the clamping plates according to the diameter of the steel strand, ensuring that each strand receives a uniform clamping force. This design is particularly suitable for steel strands of different diameters, ensuring that each strand is firmly clamped and preventing slippage caused by improper clamping plate positioning. Construction workers can select different diameter steel strands for laying according to actual needs without replacing the entire device, saving time and costs. Furthermore, the steel strand locking device 300 is made of wear-resistant materials. The application of wear-resistant materials makes the device 300 resistant to wear during long-term use, maintaining a stable clamping effect. Especially under high tensile force and frequent use conditions, the wear-resistant material effectively resists friction and wear, ensuring that the steel strand locking device 300 always remains in good working condition.
[0027] Furthermore, the fastening thread device 200 features an anti-loosening design to ensure it will not loosen under high tension conditions. This anti-loosening design effectively prevents the fastening thread device 200 from loosening under high tension, ensuring the elastic element 400 maintains sufficient pressure to push the steel strand locking device 300 to clamp the steel strand. This design is particularly suitable for applications such as bridges and buildings that require long-term high tension, ensuring the device will not fail during extended use. Of course, this invention does not limit the specific structure of the anti-loosening design. Furthermore, the axial thrust spinner 500 is equipped with a shock-absorbing element. This element absorbs vibrations during the straightening of the steel strand, reducing the impact on the steel strand and the fastening device. This not only extends the service life of the steel strand and the fastening device but also ensures the stability of the entire system. Simultaneously, the shock-absorbing element buffers external impact forces during the straightening of the steel strand, preventing steel strand breakage or damage to the fastening device due to impact. This is particularly suitable for applications requiring frequent stretching of the steel strand, ensuring construction safety and reliability.
[0028] Furthermore, this utility model does not limit the specific connection relationship between the main body 120 and the base 130. Preferably, the main body 120 and the base 130 are integrally formed. This integral design makes the main body 120 and the base 130 a single unit, eliminating the connection points between them and enhancing the structural strength of the entire device. This is particularly suitable for applications requiring high tensile strength, ensuring that the device will not deform or be damaged due to uneven stress during prolonged use. Furthermore, the elastic element 400 is a spring, which provides stable elastic support, ensuring that the fastening thread device 200 effectively compresses the elastic element 400 when tightened, pushing the steel strand locking device 300 to clamp the steel strand. This design is particularly suitable for applications requiring frequent adjustments to the clamping force, ensuring that the device is always in good working order.
