[0002] In the construction industry, for the finger gallery roof of an airport project, beam string structure components are usually used. The components of the beam string structure (constituent parts of the beam string structure) are usually assembled on a ground falsework. While assembling the beam string structure, operations such as cambering and welding and fixing are carried out.

[0003] After the beam string structure components are assembled, hoisting operations need to be carried out. A pin with a diameter of 100 mm is used for fixed connection between the beam string structure and the column head. After the fixed connection is completed, the camber of the beam string structure cannot be adjusted. Therefore, when assembling the beam string structure components on the ground, the accuracy of the camber of the beam string structure needs to be controlled extremely precisely.

[0004] For the traditional camber of the beam string structure components on the ground falsework, during installation, the camber accuracy is controlled by actual measurement. However, in the actual operation process, due to the lack of professional tools for measuring the camber of the beam string structure, it is difficult to control the camber radian, and it is difficult to check the errors generated by the radian in real time during the welding and assembly process and the hoisting and installation process, thus seriously affecting the camber accuracy of the beam string structure.

[0005] Based on the above technical problems, there is an urgent need for a solution that can accurately measure the installation accuracy of the beam string structure in each link of the installation of the beam string structure components. Summary of the Utility Model

Figure 2 The first - state picture when measuring at the first key - point position in the cable - stayed beam installation accuracy calibration device provided by the embodiment of the present utility model is shown. Figure 3 The second - state picture when measuring at the first key - point position in the cable - stayed beam installation accuracy calibration device provided by the embodiment of the present utility model is shown. Figure 4 The first - state picture when measuring at the second key - point position in the cable - stayed beam installation accuracy calibration device provided by the embodiment of the present utility model is shown. Figure 5 The second - state picture when measuring at the second key - point position in the cable - stayed beam installation accuracy calibration device provided by the embodiment of the present utility model is shown.

[0034] Combined with Figures 1 to 5 As commonly shown, the cable - stayed beam installation accuracy calibration device provided by the embodiment of the present utility model includes an infrared emitter 1 arranged at one end of the cable - stayed beam (usually arranged at the preset center position of the steel column head of the cable - stayed beam). The infrared emitter 1 can emit infrared rays 3 in the required direction as needed. At the other end of the cable - stayed beam (usually arranged at a preset position of the steel column head of the cable - stayed beam), a first main infrared receiving target 2 is fixedly arranged. In the initial state, the infrared rays 3 emitted by the infrared emitter 1 are aligned with the first main infrared receiving target 2. Through the information such as the length and inclination angle of this infrared ray 3, the coordinates of the two positions at the front and rear ends of the cable - stayed beam can be determined.

[0035] To achieve the reception of the infrared ray 3 that returns to the position of the infrared emitter 1, a second main infrared receiving target 4 is provided on the infrared emitter 1; moreover, multiple arch key points are marked at preset positions on the beam string structure, and auxiliary infrared receiving targets are provided at each arch key point; a mirror 6 with a reflecting function is provided below the arch key point, and the infrared emitter 1 cooperates with the main infrared receiving target, the auxiliary infrared receiving target, and the mirror 6 to calibrate the installation accuracy of the beam string structure.

[0036] Specifically, during actual use, first adjust the angle of the mirror 6 so that the infrared ray 3 emitted by the infrared emitter 1 can accurately hit the center of the mirror 6. After being reflected by the mirror 6, the infrared ray 3 enters the second main infrared receiving target 4. By measuring the path of the infrared ray 3, the accurate distance from the infrared emitter 1 to the mirror 6 and the inclination angle between these two points can be measured; then, tilt and flip the mirror 6 so that the infrared ray 3 emitted by the infrared emitter 1 enters the auxiliary infrared receiving target exactly after being reflected by the mirror 6. At this time, by measuring the path of the infrared ray 3, the distance from each arch key point to the mirror 6 and the inclination angle between the two points can be measured. Based on the above-mentioned measured accurate distance from the infrared emitter 1 to the mirror 6 and the inclination angle between these two points, the distance from each arch key point to the infrared emitter 1 and the inclination angle between these two points can be measured. Also, since the position coordinates of the infrared emitter 1 are known, the coordinates of each arch key point and the arch radian can be determined.

[0037] During actual operation, multiple arch key points are usually set. For example, the arch key points include a first key point 5 and a second key point 10, and the auxiliary infrared receiving targets include a first auxiliary infrared receiving target 9 and a second infrared receiving target 11; among them, the first auxiliary infrared receiving target 9 is set at the position of the first key point 5, and the second infrared receiving target 11 is set at the position of the second key point 10; the coordinates of these two positions and the arch radian are accurately measured through the cooperation of the above two arch key points and the corresponding infrared receiving targets.

[0038] In addition, to improve the utilization rate of the mirror 6, each arch key point can share a mirror 6 with a movable position. To achieve the position movement of the mirror 6, a traveling mechanism can be provided below the beam string structure. The mirror 6 is mounted on the traveling mechanism and can move back and forth between the positions below each arch key point.

[0039] To achieve the position movement of the traveling mechanism driving the mirror 6, the traveling mechanism can include a horizontal sliding track 8 provided below the beam string structure. A vertically arranged support rod 7 is slidably connected to the horizontal sliding track 8. The mirror 6 is fixed to the upper end (the end far from the support rod 7) of the support rod 7. The horizontal sliding track 8 is laid between the corresponding positions directly below each arch key point.

[0040] In addition, since the heights of the key points of each camber are different, the corresponding positions below them are also different. To ensure that the infrared rays 3 emitted by the infrared emitter 1 can all hit the centers of the mirrors 6 at different positions exactly, the support rod 7 can be set as a lifting support rod 7, and the height of the mirrors 6 at different positions can be adjusted through the lifting support rod 7.

[0041] In addition, to realize the angle adjustment of the mirror 6, a rotating buckle can be arranged at the upper end of the support rod 7. The mirror 6 is fixed to the upper end of the support rod 7 through the rotating buckle, and the inclination angle of the mirror 6 can be adjusted through the rotating buckle. To realize the convenient installation of the infrared emitter 1, a magnetic base can be arranged on the infrared emitter 1. The infrared emitter 1 is fixed to one end of the beam string structure through the magnetic base. By using the magnetic base, not only can the infrared emitter 1 be fixed, but also the disassembly of the infrared emitter 1 is facilitated, improving its installation convenience.

[0042] It should be noted that components such as the horizontal sliding track 8, the lifting support rod 7, the rotating buckle, and the magnetic base are all common structural components in the mechanical field. The working principles of each component are described in detail in many existing documents. Moreover, the solution provided by the present utility model mainly uses the functions of the above components. Therefore, the specific working principles of the above components will not be elaborated herein.

[0043] Furthermore, to improve the infrared receiving effect of each infrared receiving target, the first main infrared receiving target 2, the second main infrared receiving target 4, the first auxiliary infrared receiving target 9, and the first auxiliary infrared receiving target 9 can all be set as transparent targets; and cross marks are printed at the central positions of the first main infrared receiving target 2, the second main infrared receiving target 4, the first auxiliary infrared receiving target 9, and the first auxiliary infrared receiving target 9 to ensure that the infrared rays 3 can hit the centers of the infrared receiving targets exactly through the cross marks.

[0044] As described above with reference to Figures 1 to 5 The beam string structure installation accuracy calibration device according to the present utility model is described by way of example. However, those skilled in the art should understand that various improvements can be made to the beam string structure installation accuracy calibration device proposed by the present utility model without departing from the content of the present utility model. Therefore, the protection scope of the present utility model should be determined by the content of the appended claims.
