DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0030] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0031] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0032] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0033] like Figures 1-5 As shown, a cable-stayed bridge wind-resistant maintenance vehicle device of the present invention includes a maintenance vehicle a, a cable-stayed bridge b to be maintained, a lower cable-stayed bridge c, a wind-resistant component 1, and a stabilizing rope 2, wherein...

[0034] The maintenance vehicle a is installed on the cable-stayed bridge b to be maintained, and the wind-resistant component 1 is installed on the lower cable-stayed bridge c. The lower cable-stayed bridge c is located below the cable-stayed bridge b to be maintained. The maintenance vehicle a is connected to the wind-resistant component 1 via a stabilizing rope 2. The stabilizing rope 2 is elastic and always taut, and it and the two connection points at the bottom of the maintenance vehicle a form a stable triangular structure (e.g., ...). Figure 5 (As shown).

[0035] In the above technical solution, throughout the process, the stabilizing rope 2 connects the maintenance vehicle a and the wind-resistant component 1. By adjusting the connection between the wind-resistant component and the stabilizing rope, the stabilizing rope 2 is kept in a taut state. The lower cable c and the elastic, taut stabilizing rope 2 are used to simultaneously tighten and stabilize the maintenance vehicle. This can solve the problem of poor wind resistance of the cable-stayed maintenance vehicle in ultra-high-altitude operation environments, enabling the cable-stayed maintenance vehicle to still operate smoothly under permissible wind conditions and ensuring safety.

[0036] The angle a formed by the side of the stabilizing rope 2 and the lower side cable c where the wind-resistant assembly 1 is located is not greater than 45°, which is to increase the length of the stabilizing rope as much as possible in the case of two cables being fixed, and to ensure that the length of the stabilizing rope cannot be too short, so as to provide space for subsequent adjustment of the length of the stabilizing rope according to actual needs; the self-weight of the wind-resistant assembly is 1%-5% of the self-weight of the maintenance vehicle, so as to avoid that the wind-resistant assembly is too light or too heavy, the wind-resistant effect is not obvious when the wind-resistant assembly is too light, and the traction of the maintenance vehicle is increased when the wind-resistant assembly is too heavy.

[0037] When the maintenance vehicle a suddenly encounters a gust of wind or the wind speed increases during operation, the wind-resistant assembly is added on the basis of the conventional maintenance vehicle, so that the sum of the anti-rotation moment of the wind-resistant assembly and the self-weight of the maintenance vehicle along the cable under the condition of a sudden gust of wind is greater than the rotation moment of the wind load on the maintenance vehicle (as shown in the following formula 1), so as to maintain the stability of the maintenance vehicle:

[0038] F Z L1 + F G L2≥F w L3 Formula 1

[0039] In the formula:

[0040] F Z : the component of the pulling force of the wind-resistant assembly on the maintenance vehicle perpendicular to the axis of the cable to be maintained when the maintenance vehicle has a tendency to overturn;

[0041] L1: the force arm corresponding to the component of the pulling force of the wind-resistant assembly on the maintenance vehicle perpendicular to the cable to be maintained;

[0042] F G : the component of the gravity of the maintenance vehicle perpendicular to the axis of the cable to be maintained when the maintenance vehicle has a tendency to overturn;

[0043] L2: the force arm of the component of the gravity of the maintenance vehicle perpendicular to the axis of the cable to be maintained;

[0044] F w : the equivalent wind load that makes the maintenance vehicle have a tendency to overturn;

[0045] L3: the force arm corresponding to the equivalent wind load that makes the maintenance vehicle have a tendency to overturn;
