Description

Oblique bridge cable damping damper

The invention relates to a diagonal bridge cable damping damper, in particular to an innovative structural designer capable of effectively reducing the shaking of a diagonal bridge due to strong wind or earthquake.

According to the cable-stayed bridge cable, the exposed pre-forced steel shackle and the like, the cable elements are composed of single-strand cable components of steel wire or steel strand, which are located together with the casing inside the cable. After passing through the relevant structure, it is fixed at the end with an anchor device. Please refer to Figure 4, which is a schematic view of the appearance of a conventional oblique bridge (A), which mainly comprises a column (A1) and a bridge (A2), and is connected by a plurality of cables (A3) in an oblique shape. The column (A1) and the bridge (A2) are in a supporting state. However, the conventional sloping bridge (A) is often prone to severe shaking due to strong winds or earthquakes, and thus it is easy to cause a risk of high-speed driving of vehicles passing through the bridge.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical, and to use the eagerly awaited by consumers, is also the goal and direction of the relevant industry to strive to develop breakthroughs.

In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the inventor has finally obtained the practical invention.

That is, the main object of the present invention is to provide a sway bridge cable vibration damper; the problem to be solved is that it is often easy to be built by strong wind or earthquake for a conventional slant bridge. It is violently shaken, which is easy to cause a breakthrough in the dangers caused by high-speed driving of the vehicles passing through the bridge; and the technical features of the problem solving are mainly through the cable damping damper for connecting to a diagonal bridge. The column and the bridge are supported by the plurality of cables; wherein the cable damping damper comprises a plurality of electromagnet units and a plurality of coil units, and each of the electromagnet units and the coil units are aligned with each other and arranged side by side The cable is characterized in that each of the electromagnet units includes a first damper, and the first damper is positioned on the cable, wherein the first damper ring side is provided with a plurality of first damper ends, wherein each of the cables The first damper end itself has a current; and each of the coil units includes a second damper, the second damper is positioned on the cable, and the second damper corresponds to the first damper of each of the electromagnet units Corresponding position, the second damper ring side is provided with a plurality of second damper ends, and each of the second damper end surface rings is covered with a plurality of coils, so that the second damper ends Positioned at a position opposite to each of the first damper ends, and each of the electromagnet units itself has a current, so that the first damper end and the second damper end are opposite to each other. The method is that the two ends are mutually repulsive and mutually repulsive; the innovative and unique design enables the oblique bridge cable damping damper of the present invention to be disposed on each of the cables of the inclined bridge, by each of the electromagnet units And the coil units are aligned with each other and arranged in parallel with each other to form an isotropic repulsion principle of the electrodes, which can effectively reduce the shaking of the inclined bridge due to strong wind or earthquake.

Please refer to FIGS. 1~3, which are preferred embodiments of the cable-stayed cable damper of the present invention, but the embodiments are for illustrative purposes only and are not limited by the structure in the patent application: The cable damping damper described in the diagonal bridge cable damping damper of the present invention is used for connecting to a plurality of cables (A3) supported by a column (A1) and a bridge (A2) included in a diagonal bridge (A). Each of the cable (A3) damping dampers includes a plurality of electromagnet units (10) and a plurality of coil units (20), and each of the electromagnet units (10) and each of the coil units (20) are aligned with each other. And staggered and arranged side by side on each of the cables (A3); characterized in that each of the electromagnet units (10) comprises a first damper (11), the first damper (11) is positioned on the cable (A3) The first damper (11) is provided with a plurality of first damper ends (12), wherein each of the first damper ends (12) itself has a current; and each of the coil units (20) includes a second a damper (21), the second damper (21) is positioned on the cable (A3), and the second damper (21) corresponds to the first damper of each of the electromagnet units (10) (11) Corresponding position, the second damper (21) is provided with a plurality of second damper ends (22) on the ring side, and each of the second damper ends (22) is covered with a plurality of coils, wherein each coil unit (20) The number of coils covered by the surface of the second damper end (22) can be used to control the current intensity, so that each of the second damper ends (22) is located at a position opposite to each of the first damper ends (12). And because each of the electromagnet units (10) itself has a current, the positive and negative electrodes of the first damper end (12) and the second damper end (22) are opposite to each other. For the same pole to repudiate the form.

Thereby, the diagonal bridge cable damping damper of the present invention is disposed on each of the cables (A3) of the diagonal bridge (A), and each of the electromagnet units (10) and each The coil unit (20) is aligned with each other and arranged in a staggered manner on the principle of the same-sex repelling of the electrodes generated by the cables (A3), and can effectively reduce the shaking of the oblique bridge (A) due to strong wind or earthquake. .

By summarizing the above description, the design of the above structure of the present invention can effectively overcome the shortcomings faced by the conventional invention, and further has the above-mentioned numerous advantages and practical values. Therefore, the present invention is an innovative invention and is identical in the same No identical or similar product creation or public use has been found in the technical field.
