Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
Referring to fig. 1 to 3, a power transmission tower having a truss up-down function, including a tower head, a tower body 1 and tower legs, includes: the truss groups 2 are symmetrically arranged on two sides of the tower body 1; and a lifting device 3 driving the truss to move. The lifting device 3 includes: a power unit 31 provided in the tower body 1; and the linear sliding table module 32 is fixedly arranged on the side surface of the tower body 1, and the linear sliding table module 32 is respectively connected with the power device 31 and the truss. Straight line slip table module 32 includes: the first linear sliding table group 321 is symmetrically and fixedly arranged on the side surface of the tower body 1; and the second linear sliding table group 322 is arranged on the outer side of the first linear sliding table group 321 and symmetrically and fixedly arranged on the side surface of the tower body 1. The truss group 2 includes: the first truss 21 is fixedly arranged at the bottom of the side surface of the tower body 1; a second truss 22 disposed above the first truss 21 and connected to the first linear stage group 321; and a third truss 23 disposed above the second truss 22 and connected to the second linear stage group 322. The arrangement of the linear sliding table group improves the movement precision and stability of the truss. When meetting the condition of defense strong wind weather, thereby drive sharp slip table module 32 through power device 31 and drive truss group 2, realize that second truss 22 and third truss 23 are close to first truss 21 direction for the cable on the different trusses shortens distance each other, reaches the effect that reduces transmission tower and rocks the range. Similarly, when the strong wind weather subsides, thereby drive straight line slip table module 32 through power device 31 and drive truss group 2, realize that second truss 22 and third truss 23 move to keeping away from first truss 21 direction for the cable on the different trusses pulls open certain distance, resumes normal shape.
Referring to fig. 2 to 3, the power unit 31 includes: a motor 311; a first transmission shaft 312 connected to the motor 311; second transmission shafts 313 respectively connected to both ends of the first transmission shaft 312; and gear sets 314 arranged at two ends of the second transmission shaft 313, wherein the gear sets 314 are connected with the linear sliding table module 32.
