[0002] A single-tower single-span suspension bridge with an earth anchor rotary cable is a new type of bridge structure. It uses a single bridge tower and transfers the tension of the main cable to the foundation through the earth anchor rotary cable to form a stable structural system. The characteristics of this type of bridge are that its single-tower structure can effectively reduce the impact on the surrounding environment. At the same time, the design of the earth anchor rotary cable makes the bridge visually more concise and also has more advantages in terms of structural mechanical properties.

[0003] The cable strand measurement of a single-tower single-span suspension bridge with an earth anchor rotary cable can ensure the smooth alignment of the main cable, improve the overall performance and service life of the bridge. The alignment adjustment accuracy of the main cable is mainly controlled by the alignment adjustment accuracy of the reference cable strand, and other cable strands (general cable strands) are relatively controlled according to the alignment of the reference cable strand. Therefore, to ensure the accuracy of the general cable strands, it is necessary to measure the sag difference between the general cable strands and the reference cable strand.

[0004] However, in the process of implementing the related technical solutions, it is found that there are at least the following technical problems: When measuring multiple general cable strands, it is necessary to measure the distances in two vertical directions between the general cable strands and the reference cable strand at the same height, and two rulers need to be used for measurement respectively. Measuring the distance between the cable strands is rather troublesome, which affects the measurement efficiency and accuracy. Summary of the Utility Model

Detailed implementation manner

[0018] The embodiment of the present application discloses a device for measuring and positioning the alignment of general cable strands of an earth-anchored slewing cable single-tower single-span suspension bridge. The vertical distance between the general cable strand 102 and the reference cable strand 101 is measured by the first scale line 17 on the fixing plate 11 and the extension plate 12, and the horizontal distance between the general cable strand 102 and the reference cable strand 101 is measured by the second scale line 22 on the horizontal plate 21, so as to quickly and accurately measure the sag difference between multiple general cable strands 102 and the reference cable strand 101.

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0020] Please refer to Figure 1 and Figure 2 , this embodiment provides a device for measuring and positioning the alignment of general cable strands of an earth-anchored slewing cable single-tower single-span suspension bridge, including a vertical measurement component 10. Horizontal measurement components 20 are arranged at both ends of the vertical measurement component 10. The two horizontal measurement components 20 are symmetrically arranged. The two horizontal measurement components 20 are installed at both ends of the vertical measurement component 10 through a fixing component 30. The vertical measurement component 10 includes a fixing plate 11, an extension plate 12, a sliding groove 13, a first spring 14, a mounting block 15, a limiting groove 16, and a first scale line 17. The fixing plate 11 is arranged between the two horizontal measurement components 20. The extension plate 12 is inserted and connected to one end of the fixing plate 11. The sliding groove 13 is opened at one end of the fixing plate 11. The extension plate 12 is slidably connected to the inside of the sliding groove 13. The first spring 14 is fixedly arranged inside the sliding groove 13. Both ends of the first spring 14 are fixedly connected to the inner wall of the sliding groove 13 and the extension plate 12 respectively. The first scale line 17 is fixedly arranged on one side of the fixing plate 11 and the extension plate 12. The horizontal measurement component 20 can be a scale. The retractable fixing plate 11 and extension plate 12 can increase the measurement range. The vertical distance between the general cable strand 102 and the reference cable strand 101 is measured by the first scale line 17 on the side of the fixing plate 11 and the extension plate 12. Through the elastic force of the first spring 14 inside the sliding groove 13, the two scales can be made to closely adhere to the general cable strand 102 and the reference cable strand 101, making the measurement result more accurate.

[0021] Please refer to Figure 1 ,Figure 2 and Figure 3 Among them, the two horizontal measurement components 20 include a horizontal plate 21, a second scale line 22, a horizontal bubble level 23, and a mounting groove 24. The two horizontal plates 21 are respectively arranged at one end of the fixed plate 11 and the extension plate 12. The second scale line 22 is fixedly arranged on the side of the horizontal plate 21 close to the fixed plate 11. The horizontal bubble level 23 is fixedly arranged on the other side of the top of the horizontal plate 21. The mounting groove 24 is opened at one end of the horizontal plate 21 close to the fixed plate 11. The mounting block 15 is fixedly arranged at the other end of the fixed plate 11, and the extension plate 12 and the mounting block 15 are matched with the mounting groove 24 in size. By the position of the bubble in the horizontal bubble level 23 on the horizontal plate 21, it is ensured that the horizontal plate 21 remains horizontal, so that the fixed plate 11 and the extension plate 12 perpendicular to it are in the same horizontal plane as the two horizontal plates 21, preventing measurement errors caused by inclination. By the difference between the general strand 102 and the reference strand 101 at the second scale line 22 on the side of the two horizontal plates 21, the horizontal distance between the general strand 102 and the reference strand 101 is measured. Combining with the value of the first scale line 17, the distance between the general strand 102 and the reference strand 101 can be quickly measured, and the distances between multiple general strands 102 and reference strands 101 can be quickly measured, making it more convenient to use. Therefore, after measuring the vertical distance and the horizontal distance between the general strand 102 and the reference strand 101, the general strand 102 can be adjusted according to the measured data. The schematic diagram of the adjusted general strand 102 is as shown in Figure 4 shown.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 , limit grooves 16 are opened at the tops of the extension plate 12 and the mounting block 15. The fixing component 30 includes a plug rod 31, a fixing block 32, and a second spring 33. The plug rod 31 is inserted and connected to one end of the top of the horizontal plate 21 close to the fixed plate 11, and the plug rod 31 is matched with the limit groove 16 in size. The shapes of the limit groove 16 and the plug rod 31 are both square. The fixing block 32 is fixedly arranged at the top of the plug rod 31. The second spring 33 is sleeved on the outside of the plug rod 31, and the two ends of the second spring 33 are respectively fixedly connected to the horizontal plate 21 and the fixing block 32. By inserting the plug rod 31 into the limit groove 16 on the extension plate 12 and the mounting block 15, the fixed plate 11 and the extension plate 12 are fixed to the two horizontal plates 21. The square limit groove 16 and the plug rod 31 can ensure the accurate insertion angle, ensuring that the fixed plate 11 and the extension plate 12 are perpendicular to the horizontal plate 21. Due to the elastic force of the second spring 33, the plug rod 31 has a tendency to move downward, so that the fixed plate 11 and the extension plate 12 will not be separated from the horizontal plate 21 randomly. The two horizontal plates 21 can be detached from the fixed plate 11 and the extension plate 12, reducing the overall floor area of the measuring device and making it convenient to carry around.

[0023] The functional principle of this application can be described through the following operation method:

[0024] During use, pull out the fixing blocks 32 on the two horizontal plates 21 upwards, insert the mounting blocks 15 on the extension plate 12 and the fixing plate 11 into the mounting grooves 24 on one side of the two horizontal plates 21 respectively, release the fixing blocks 32, so that the elastic force of the second spring 33 drives the insertion rod 31 to insert into the limiting groove 16 inside the mounting groove 24, fix the two horizontal plates 21 on the fixing plate 11 and the extension plate 12 respectively, make the inner side of one horizontal plate 21 closely adhere to the reference cable strand, pull out the extension plate 12 outwards, so that the general cable strand 102 to be measured is arranged on the inner side of the other horizontal plate 21, the elastic force of the first spring 14 inside the sliding groove 13 makes the other horizontal plate 21 closely adhere to the general cable strand 102, when measuring, observe the position of the bubble on the horizontal bubble level 23 to make the two horizontal plates 21 keep horizontal, so that the fixing plate 11 and the extension plate 12 are in the same horizontal plane as the two horizontal plates 21, observe the reading of the second scale line 22 corresponding to the general cable strand 102 and the reference cable strand 101 to know the horizontal distance, add the reading of the first scale line 17 on one side of the fixing plate 11 and the reading of the first scale line 17 on one side of the extension plate 12 to know the vertical distance, thus measuring the distance between the general cable strand 102 and the reference cable strand 101, repeat the operation to measure other general cable strands 102, achieving the effect of quickly and accurately measuring the distance in two perpendicular directions between the general cable strand 102 and the reference cable strand 101.
