Problems solved by technology

In recent years, many people have conducted research on the positioning technology of scatter-cable saddles. However, because the design of scatter-cable saddle structures is mostly linear in space and angle control is difficult, the existing positioning technology has certain drawbacks and the work efficiency is extremely low.

Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0034] see figure 1 , the present invention provides a kind of accurate positioning method of suspension bridge scattered cable saddle based on APP system, the specific steps are as follows:

[0035] A. Coordinate calculation of the design cross line of the bottom plate of the scattered cable saddle:

[0036] Calculate the coordinates of the design cross line of the scatter cable saddle base plate 1 according to the coordinate positive calculation formula and the spatial position relationship of the scatter cable saddle base plate 1; use CAD to build a 1:1 model of the scatter cable saddle, and pass the calculated coordinates through the way of exhibition points. Expand it to the CAD drawing, and check the coordinates of the design cross line of the bottom plate 1 of the scatter cable saddle;

[0037] B. The positioning...

Abstract

The invention proposes an APP system-based precise positioning method for a scatter saddle, which includes the following steps: using the coordinate positive algorithm and the space position relationship of the scatter saddle bottom plate to calculate the coordinates of the design cross line of the scatter cable saddle bottom plate; drawing the scatter cable saddle 1:1 three-dimensional map, coordinate review; compile an APP system, which can connect the total station and the APP system through Bluetooth, transmit the actual measurement data of the total station to the APP system in real time, and automatically calculate the loose cable saddle Adjustment parameters of the bottom plate and saddle body; calculate the adjustment parameters of the bottom plate of the scatter cable saddle through the positional relationship between the spatial point and the line, and adjust the bottom plate of the scatter cable saddle by using a jack at each part; The dihedral angle of the saddle reflects the angle of the measured saddle axis, and the angle of the saddle axis is adjusted by the spreader on the sling saddle mast.

Description

technical field [0001] The invention relates to the field of measurement, in particular to an APP system-based method for accurate positioning of a stray saddle of a suspension bridge, which is especially suitable for the accurate positioning of a stray saddle of a suspension bridge with complex spatial structure design. Background technique [0002] Since the beginning of the 21st century, my country's bridge construction has developed rapidly. Suspension bridges have become the main form of long-span bridges because of their flexibility, beauty, and suitability for high wind and earthquake areas. The cable saddle of a suspension bridge supports and fixes the main cable, and its design, construction quality, and positioning accuracy control are very important. In recent years, many researchers have studied the positioning technology of the cable saddle. However, because the design of the cable saddle structure is mostly linear in space and the angle control is difficult, th...
