The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
Referring to fig. 1-3, the utility model provides a steel arch tower vertical rotation monitoring device, which is used for monitoring a real-time state of a steel arch tower during vertical rotation in practical application, and comprises a vertical rotation tower 1, steel arch towers 2 arranged on two sides of the vertical rotation tower 1, a vertical rotation cylinder group 3 arranged on the vertical rotation tower 1, and a swivel cable 4 connecting the vertical rotation cylinder group 3 with the steel arch tower 2. Wherein the number of the steel arch towers 2 is two groups and symmetrically arranged about the vertical rotating tower 1.
It can be understood that before the steel arch tower 2 is vertically rotated, a constructor is constructed on the pier of the bridge at the center of the river, and a base hinged with the steel arch tower 2 is arranged on the pier, and by hinging the steel arch tower 2 with the base, the steel arch tower 2 can be pulled to vertically rotate by using the vertical rotation cylinder group 3 arranged on the vertical rotation tower 1 to pull the rotating rope 4 connected with the steel arch tower 2, and the hinged position is taken as an axis.
It can be understood that by arranging the steel arch towers 2 on both sides of the vertically rotating tower 1 and symmetrically arranging the steel arch towers about the vertically rotating tower 1, and simultaneously arranging the vertically rotating cylinder groups 4 on both sides of the vertically rotating tower 1 symmetrically about the vertically rotating tower 1, the steel arch towers 2 are pulled by the vertically rotating cylinder groups 3 to synchronously perform vertical rotation, so that acting forces acting on both sides of the vertically rotating tower 1 are mutually offset.
Further, the connection between the swivel cable 4 and the steel arch tower 2 is a hanging point, each group of hanging points is simultaneously connected with a group of vertical rotating cylinders, in a preferred embodiment, the hanging points on the two groups of steel arch towers 2 are respectively symmetrically arranged with respect to the vertical rotating tower 1, so that the two sides of the vertical rotating tower 1 are in stress balance during the vertical rotating process of the steel arch tower 2.
In a more preferred embodiment, referring to fig. 2 and 3, the central axis of the steel arch tower 2 is taken as a dividing line, the number of hanging points arranged at one side of the steel arch tower 2 is multiple, and the connecting lines of the multiple hanging points are parallel to the vertical rotating tower 1; and the swivel ropes 4 connected with the same side hanging point of the steel arch tower 2 are mutually parallel, so that the swivel ropes 4 connected with the same side hanging point of the steel arch tower 2 have the same stroke in the synchronous vertical rotation process.
For example, referring to fig. 3, the hanging points on the steel arch tower 2 are P1 and P2 respectively, the cylinders on the vertically rotating tower 1 are S1 and S2 respectively, wherein the hanging point P1 is connected to the vertically rotating cylinder S1, the hanging point P2 is connected to the vertically rotating cylinder S2, and the connecting lines between the hanging points P1, P2, S1 and S2 are rectangular, so that the strokes of the vertically rotating cylinder S1 and the vertically rotating cylinder S2 are the same in the rising process of the hanging points P1 and P2.
Further, each group of hanging points is provided with a height sensor and a first travel sensor, wherein the height sensor is used for detecting the real-time height of the corresponding hanging point, and the first travel sensor is used for detecting the travel distance of the corresponding hanging point in the vertical rotation process.
