Cable Stayed Bridges movable multiple hinge and energy saving driving method thereof

摘要

The present invention is directed to a cable-stayed bridge multi-hinge movable bridge and a method of driving the same that reduces the cost and efficiency of a bridge by combining a bridge type bridge with a cable-stayed bridge type bridge. In order to accomplish the above object, the present invention provides a cable-stayed multi-hinge movable bridge comprising: a main tower installed on a shore and spaced apart by a predetermined width and having a predetermined height; A top plate segment horizontally disposed below the main tower and comprising at least two or more segments; A hinge inserted between the top plate segments; A cable fixedly installed between the main tower and the hinge; The cables are installed on the main tower bottom so as to be driven is rotated the upper segment, a motor and a plurality of pulleys is composed of a drive unit composed of the hinge of the first cable, the length of the cable pulling the hinge pulling ℓ _1, the second hinge ℓ ₂ , and the length of the third pulling cable is ℓ ₃ , the length of the cable after finally lifting the top segment is ℓ '' ₁ , ℓ'' ₂ , ℓ '' ₃ . If the length ratio is expressed as DELTA _{l 1} , DELTA l ₂ , DELTA l ₃ , the length ratio of DELTA _l : DELTA l ₂ : DELTA l ₃ = 1: 1.21: _{1.21:: Δℓ 1, Δℓ 2} , Δℓ 3 1 according to consist of 1.1, is characterized in that the top plate configured to segment the two more folded by an internal hinge. According to another aspect of the present invention, there is provided an energy-reduction driving method for a cable-stayed multi-hinge movable bridge including a main tower on both sides of a revetment, A cable is installed between the main tower and the hinge, a driving unit including a motor and a plurality of pulleys is disposed below the main tower, a cable is connected to the driving unit, and the cable wound on, by solving, but configured such that rotation of the upper segment, the length of the cable pulling the first hinge of the hinge ℓ _1, both the length of the cable pulling the second hinge ℓ _2, the length of the third pulling cable in the case considered ℓ _3, each of the length of the cable after finally lift the upper segment Let ℓ ₁ , ℓ ₂ , and ℓ ₃ denote the length ratio of the cable to be drawn by Δℓ ₁ , Δℓ ₂ and Δℓ ₃ , respectively. The length ratio of Δℓ ₁ : Δℓ ₂ : Δℓ ₃ = 1: 1.21: 1.1 Wherein the size ratio of the pulleys pulling the cables is 1: 1.21: 1.1 according to the length ratio of the cables, and the top plate segments are folded twice by the inner hinges.
