[0036] Main cable selection

[0037]

[0038] Auxiliary rope selection

[0039]

[0040] In some embodiments, the calculation formula of the length of the main cable is:

[0041] Single main cable L1: L1=A+2B+2C+2D+2E;

[0042] Two main cables L2: L=2×(A+2B+2C+2D+2E);

[0043] Wherein, C=1.5B, D=0.03A, and E=2.

[0044] The accuracy of the main load-bearing structure design is ensured, the installation efficiency is improved, and the on-site adjustment is reduced.

[0045] In some embodiments, the calculation formula of the length of the left and right motion auxiliary ropes is:

[0046] Single left and right motion auxiliary rope L3: L3=2A1+3B1+2C1+2D1;

[0047] Wherein, C1=0.03A1, and D1=3.

[0048] By the length algorithm of the translational motion, the motion stroke and the required margin for vertical amplitude and fastening are accurately reserved, the horizontal movement is ensured to be smooth and stable, and the reliability of the equipment operation is improved.

[0049] In some embodiments, the calculation formula of the length of the lifting motion auxiliary ropes is:

[0050] Single lifting motion auxiliary rope L4: L4=A1+3B1+2C1+2D1;

[0051] Two lifting motion auxiliary ropes L5: L5=2×(A1+3B1+2C1+2D1);

[0052] Wherein, C1=0.03A1, D1=3.

[0053] By distinguishing the calculation formula of single and double cable working conditions, the length of the lifting rope is accurately determined, the synchronization and safety of the lifting process are effectively guaranteed, and the winding efficiency of the reel is optimized.

[0054] In some embodiments, the tower spacing A is in the range of 10 meters≤A≤500 meters; the tower height B is in the range of 5 meters≤B≤60 meters; the tower spacing A1 is in the range of 10 meters≤A≤500 meters; the tower height B1 is in the range of 5 meters≤B≤60 meters. By limiting the reasonable value range of the tower spacing and height, an explicit and reliable engineering application boundary is provided for the entire calculation method, ensuring the effectiveness and accuracy of the calculation formula and coefficient within this range, effectively preventing the distortion of the calculation results or safety risks caused by parameter over-limiting, while this range covers most actual application scenarios, significantly improving the practicality and guiding value of the selection calculation method.

[0055] A selection and calculation system of cableway wire rope, which adopts the selection and calculation method of cableway wire rope according to any one of claims 1 to 6 to select and calculate the length of the rope. By integrating the above selection and calculation method into the system, the process and automation of wire rope design and calculation are realized, which greatly improves the design efficiency and result consistency, and is conducive to the standardization promotion and application of the technology.

[0056] The system establishes a main cable specification database, which stores key parameters of different specifications of load-bearing steel cables, such as M12, M16, M20, M30, etc. The corresponding design length range (such as ≤180 meters, ≤320 meters, ≤500 meters), applicable working conditions (single / double cable) and breaking tension (such as 80KN, 135KN, 205KN, 400KN) of each model. The system can automatically match and recommend the most suitable main cable specification according to the actual load capacity, tower spacing and other key design conditions input by the user through the built-in filtering algorithm.

[0057] Similarly, the system also constructs a secondary rope specification database, which covers detailed parameters of load-bearing steel cables and load-bearing ropes of M4 to M8 specifications. According to the functional type (such as left-right translation movement or up-down lifting movement) and specific load-bearing requirements of the secondary rope, the system can intelligently select and match the rope specification to ensure that its breaking tension and performance meet the actual working condition requirements.

[0058] The rope length calculation module of the system further includes the following sub-modules:

[0059] The main cable length calculation submodule is used for acquiring the tower spacing A (the value range is 10-500 meters) and the tower height B (the value range is 5-60 meters) set by a user, and automatically calculating the cable angle coefficient C (C = B x 1.5), the vertical arc coefficient D (D = A x 3%) and the fastening coefficient E of 2 meters. The single cable length is accurately calculated through the formula L = A + 2B + 2C + 2D + 2E, and the double cable length is twice the single cable length. The module effectively ensures the length accuracy of the main cable under different engineering layouts, and eliminates the installation and operation risks caused by length deviation.

[0060] The left and right motion pair rope length calculation submodule is used for acquiring the tower spacing A1 (the value range is the same as the main cable parameter) and the tower height B1, and automatically calculating the vertical arc coefficient C1 (C1 = A1 x 3%) and the fastening coefficient D1 of 3. The single cable left and right motion rope length is calculated according to the formula L = 2A1 + 3B1 + 2C1 + 2D1, and the double cable length is correspondingly doubled. In this way, the length of the transverse motion rope is optimally configured, and the support wire equipment realizes stable and reliable transverse movement.

[0061] The up and down motion pair rope length calculation submodule is also based on the input A1 and B1 parameters to calculate the vertical arc coefficient C1 and the fastening coefficient D1. The single cable lifting motion rope length is determined according to the formula L = A1 + 3B1 + 2C1 + 2D1, and the double cable length is twice the single cable result. Therefore, the rope length required for lifting operation is accurately matched, and the safety and efficiency of the wire system in the vertical direction are ensured.

[0062] Through the cooperative operation of the above database and calculation module, the system of the application can comprehensively improve the efficiency, accuracy and reliability of the cableway wire engineering design, and is suitable for various complex application scenarios.

[0063] The cableway wire rope selection and calculation method provided by the application significantly improves the safety, economy and reliability of the system design. By integrating the selection standard and the accurate calculation model, the selection errors and length deviations caused by relying on experience estimation in traditional design are effectively avoided. Not only the safety hazards caused by insufficient strength or too small installation allowance are fundamentally eliminated, but also the material waste and design repetition are greatly reduced. At the same time, the standardized parameter system is easy to popularize and apply in different projects, and provides efficient, unified and adaptable technical support for various high-altitude hanging scenes.

[0064] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalent ones.
