[0017] In a second aspect, the present invention provides a method for using a detection device based on the overall side rotation of the main and auxiliary double-limb arch ribs according to the first aspect, including the following steps: S1. Build the double-limb arch rib module in advance according to the bridge construction requirements, and the span of the double-limb arch rib module is D. Adjust the lengths of the first horizontal telescopic frame and the second horizontal telescopic frame of the telescopic fixed grid module according to the span information of the double-limb arch rib module. S2. Link and fix four horizontal moving detection frame modules and two groups of tower modules together. Then place the two groups of double-limb arch rib modules into the four horizontal moving detection frame modules. Hook the rotating cable to the rotating hinge seat. The rotating cable extends out of the rotating hinge seat, and the extension length is measured by the detector inside it. The extension length is K. S3. Install four first positioners at the middle position inside the installation pier seat, and install the second positioner on the rotating hinge seat. S4. The first positioner measures the height position information of the installation pier, and adjusts the installation pier, the detection control seat module, the lateral movement detection frame module, and the tower module to the same height through the movement module. And in a group of controllers, set the corresponding group of detection control seat modules as the coordinate origin O. The connection direction between the detection control seat module serving as the coordinate origin and the other group of detection control seat modules is the X-axis. The connection direction between the two lateral movement detection frame modules on the side of the detection control seat module serving as the coordinate origin is the Y-axis, and the vertical direction is the Z-axis, thus forming a coordinate system XOYZ. S5. The controller automation control device starts to move. The four first positioners transmit the position information to the controller in real time for analysis. The four first positioners are symmetrically arranged in pairs with the bridge length towards the center line as a group. When the control device moves to the center position, that is, the distance between the first positioner in a group and the detection control seat module is equal. When the detection control seat module is flush with the first positioner, the device stops moving. S6. Lower the stable detection L seat and the tower stable L seat, and fix the detection control seat module and the tower module through the first fixing bolt and the fifth fixing bolt. S7. The distance between the positioning module in the bottom seat frame of the initial position of the double-limb arch rib module and the coordinate origin O is J. Symmetrically extend the lateral movement detection frame module to lift the leak to the installation pier, and the seat frame is also extended and pushed to the leak, and then it falls onto the installation pier through the leak. At this time, the moving distance of the seat frame is S, and the final position of the seat frame is A(0, Y 1,0), where Y 1 = J + S ; S8. The angle meter in the arch seat measures the rotation angle of the double-limb arch rib module in real time. When it rotates 5° each time, the second positioner measures the position information of the hinge seat. The position of the hinge seat C( X 3, Y 3, Z 3), and the distance between points A and C when the rotation angle of the double-limb arch rib module is 0° is used as the comparison reference position. When the distance between A and C changes, it indicates that the double-limb arch rib module deforms in the X / Y axis direction. ; Among them, X 3 is the numerical value of the X-axis of the hinge seat (74) in the coordinate system XOYZ; Y 3 is the numerical value of the Y-axis of the hinge seat (74) in the coordinate system XOYZ; Z 3 is the numerical value of the Z-axis of the hinge seat (74) in the coordinate system XOYZ; S9. Compare the distance between the tensioning seat and the rotating hinge seat with the length of the rotating cable extending out. When the two are inconsistent, it indicates that the double-leg arch rib module deforms in the Y / Z axis direction; Position information B of the tensioning seat 53 ( X 2,0, Z 2), ; Among them, X 2 is the distance between the tower module 5 and the coordinate origin O. And the first group of tower modules 5 is at a distance of 1 / 3 of the span D of the double-leg arch rib module 7 from the coordinate origin O, and the second group of tower modules 5 is at a distance of 2 / 3 of the span D of the double-leg arch rib module 7 from the coordinate origin O. That is, the distance between the two bottom arch seats 75 is D; Z 2 is the height difference between the tensioning seat 53 and the tower base 51 in the tower module 5, and the height differences between the tensioning seat 53 and the tower base 51 in the two groups of tower modules 5 are the same; When a deformation problem occurs, stop the operation of the device, and the operator shall go to the site to confirm whether the operation can continue; S10. When there is no problem in S9, finally turn the arch seat to the seat frame, and the operator fixes and installs the double-leg arch rib module on the installation pier through an external device, and finally restore the device to its original position.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The operation method provided by the present invention is different from the traditional process. Taking the two ends of the arch foot rotating seat axis as the rotating shafts, the assembled arch rib in the lying state is rotated laterally to the installation position. Compared with the installation method of cable hoisting construction, lateral rotation can greatly reduce the content and time of high-altitude operation, and transfer most of the high-altitude splicing and welding operation content to the assembly plane operation. Compared with the traditional beam-first and arch-later hoisting method, lateral rotation only requires fewer temporary facilities to maintain the arch rib installation system. The lateral rotation construction method can complete the installation construction of the arch rib structure with lower safety risks, shorter construction periods, and lower maintenance costs.

[0019] 2. The present invention automatically adjusts and controls the movement of the device through the first positioner, facilitating the operation process of installation in place. And during the lateral rotation process, the state of the double-leg arch rib module is judged by analyzing whether the directly stressed position, the rotating hinge seat, deforms by analyzing the distance information between the rotating hinge seat and the arch seat and between the rotating hinge seat and the tensioning seat.

[0032] Further, for the starting device, the first positioner 9 measures the height position information of the installation pier 2. The installation pier 2, the detection control seat module 3, the lateral movement detection frame module 4, and the tower module 5 are adjusted to be at the same height through the third telescopic frame 84 in the mobile module 8.

When it rotates 5° each time, the position information of the rotating hinge seat 74 is measured through the second positioner 79. The position C of the rotating hinge seat 74 is ( X 3, Y 3, Z 3), and the distance between points A and C when the rotation angle of the double-limb arch rib module 7 is 0° is used as the comparison reference position. , when the distance between A and C changes, it indicates that the double-limb arch rib module 7 deforms in the X / Y axis direction. And if the AC distance in subsequent detections is less than the AC distance of the reference position, the double-limb arch rib module 7 deflects towards the coordinate origin O, otherwise it deflects away from the coordinate origin O. The distance between the tensioning seat 53 and the rotating hinge seat 74 is compared with the length K of the rotating cable 54 extended. When the two are inconsistent, it indicates that the double-limb arch rib module 7 deforms in the Y / Z axis direction. The position information of the tensioning seat 53 is B( X 2,0, Z 2), , when K > the distance of BC, the double-leg arch rib module 7 deflects in the direction away from the tower module 5.

[0034] Working principle: Before construction, the double-leg arch rib module 7 is built in advance according to the construction requirements of the bridge 1, and the span of the double-leg arch rib module 7 is D. The lengths of the first transverse telescopic frame 61 and the second transverse telescopic frame 65 of the telescopic fixed grid module 6 are adjusted according to the span information of the double-leg arch rib module 7. The first fixing block 63 and the second fixing block 69 are inserted into the tower counterweight seat 55 and fixed by the tower clamping plate 56 and the fifth fixing bolt 561. The third fixing block 67 and the fourth fixing block 68 are inserted into the transverse moving seat 41 and fixed by the transverse moving clamping plate 48 and the fourth fixing bolt 481. In this way, the four transverse moving detection frame modules 4 and the tower module 5 are linked and fixed together.

[0035] Then, the two groups of double-leg arch rib modules 7 are placed into the four transverse moving detection frame modules 4. The pressing seat shaft 78 is pressed to retract the receiving shaft 77 into the rotating seat shaft 76. The rotating seat shaft 76 at the bottom of the double-leg arch rib module 7 is placed into the first rotating seat 451 through an external lifting device. After releasing the pressing seat shaft 78, the pressing seat shaft 78 is inserted into the first rotating seat 451 to fix the double-leg arch rib module 7 to the seat frame 45. The two groups of split sliding seats 46 are inserted into the sliding rails 44 and then fixed to the seat frame 45 by the third fixing bolt 461. Then, the rotating cable 54 is hooked to the rotating hinge seat 74. The rotating cable 54 extends out of the rotating hinge seat 74, and the extending length is measured by the detector inside it. The extending length is K. At the same time, four first positioners 9 are installed at the middle position inside the installation pier seat 2, and the second positioner 79 is installed on the rotating hinge seat 74.

[0036] The device is started. The first positioner 9 measures the height position information of the installation pier seat 2. The installation pier seat 2, the detection and control seat module 3, the transverse moving detection frame module 4 and the tower module 5 are adjusted to the same height through the third telescopic frame 84 in the moving module 8. And a set of detection and control seat modules 3 are set as the coordinate origin O in the controller 37. The connecting direction of the two sets of detection and control seat modules 3 is the X-axis, the connecting direction of the front two sets of transverse moving detection frame modules 4 is the Y-axis, and the vertical direction is the Z-axis.

[0037] Then, the controller 37 automatically controls the device to start moving. The four first positioners 9 transmit the position information to the controller 37 in real time for analysis. The four first positioners 9 are symmetrically arranged in pairs along the length of the bridge 1 towards the center line as a group. When the control device moves to the center position, that is, the distance between the first positioner 9 in a group and the detection and control seat module 3 is equal. When the detection and control seat module 3 is flush with the first positioner 9, the device stops moving. The stable detection L seat 32 and the tower stable L seat 57 are lowered, and the detection and control seat module 3 and the tower module 5 are fixed by the first fixing bolt 35 and the fifth fixing bolt 58.

[0038] In the initial position of the double-leg arch rib module 7, the distance from the positioning module in the bottom seat frame 45 to the coordinate origin O is J. The symmetrically extended and horizontally moved detection frame module 4 places the leakage opening 411 on the installation pier 2, and the seat frame 45 is also extended and pushed onto the leakage opening 411, and then it falls onto the installation pier 2 through the leakage opening 411. At this time, the moving distance of the seat frame 45 is S, and the final position of the seat frame 45 is A(0, S + J, 0). The angle measurer in the arch seat 75 measures the rotation angle of the double-leg arch rib module 7 in real time. When it rotates 5° each time, the position information of the rotating hinge seat 74 is measured by the second positioner 79. The position of the rotating hinge seat 74 is C(Q, W, E), and the distance between points A and C when the rotation angle of the double-leg arch rib module 7 is 0° is used as the reference position for comparison.

[0039] When the distance between A and C changes, it indicates that the double-leg arch rib module 7 deforms in the X / Y axis direction. And if the distance between A and C in the subsequent detection angles is less than the reference distance between A and C, the double-leg arch rib module 7 deflects towards the coordinate origin O, otherwise it deflects away from the coordinate origin O.

[0040] Judge and compare the distance between the tensioning seat 53 and the rotating hinge seat 74 with the extended length K of the rotating cable 54. When the two are inconsistent, it indicates that the double-leg arch rib module 7 deforms in the Y / Z axis direction; The position information of the tensioning seat 53 is B( X 2, 0, Z 2), When K > the distance between B and C, the double-leg arch rib module 7 deflects in the direction away from the tower module 5.

[0041] When a deformation problem occurs, stop the operation of the device, and the operator goes to the site to confirm whether the operation can continue.

[0042] If there is no deformation problem, or after the deformation problem is solved, finally rotate the arch seat 75 onto the seat frame 45. The operator fixes and installs the double-leg arch rib module 7 on the installation pier 2 through an external device, and finally restores the device to its original position.

[0043] Embodiment 3: This embodiment provides a usage method of the detection device for the overall side rotation of the main and auxiliary double-leg arch ribs described in Embodiment 1 or Embodiment 2. The steps are as follows: S1. Build the double-leg arch rib module 7 in advance according to the construction requirements of the bridge 1, and the span of the double-leg arch rib module 7 is D. Adjust the lengths of the first horizontal telescopic frame 61 and the second horizontal telescopic frame 65 of the telescopic fixed grid module 6 according to the span information of the double-leg arch rib module 7; S2. Link the four lateral movement detection frame modules 4 and the tower module 5 together. Then, place the two groups of double-limb arch rib modules 7 into the four lateral movement detection frame modules 4. Hook the rotating cable 54 to the rotating hinge seat 74. The rotating cable 54 extends out of the rotating hinge seat 74, and the extending length is measured by the detector inside it. The extending length is K. S3. Install the four first positioners 9 at the middle position inside the installation pier seat 2, and install the second positioner 79 on the rotating hinge seat 74. S4. The first positioner 9 measures the height position information of the installation pier seat 2. Adjust the installation pier seat 2, the detection and control seat module 3, the lateral movement detection frame module 4, and the tower module 5 to the same height through the moving module 8. And set the corresponding detection and control seat module 3 in a group of controllers 37 as the coordinate origin O. The connection direction between the detection and control seat module 3 as the coordinate origin and the other group of detection and control seat modules 3 is the X-axis. The connection direction between the two lateral movement detection frame modules 4 on the side of the detection and control seat module 3 as the coordinate origin is the Y-axis, and the vertical direction is the Z-axis. Thus, a coordinate system XOYZ is formed. S5. The automatic control device of the controller 37 starts to move. The four first positioners 9 transmit the position information to the controller 37 in real time for analysis. The four first positioners 9 are symmetrically arranged in pairs along the length of the bridge 1 towards the center line as a group. When the control device moves to the center position, that is, the distance between the first positioner 9 in a group and the detection and control seat module 3 is equal. When the detection and control seat module 3 is level with the first positioner 9, the device stops moving. S6. Lower the stable detection L seat 32 and the tower stable L seat 57, and fix the detection and control seat module 3 and the tower module 5 through the first fixing bolt 35 and the fifth fixing bolt 58. S7. The distance between the positioning module in the bottom seat frame 45 of the double-limb arch rib module 7 at the initial position and the coordinate origin O is J. Symmetrically extend the lateral movement detection frame module 4 to place the leak port 411 on the installation pier seat 2, and the seat frame 45 is also extended and pushed to the leak port 411 and falls onto the installation pier seat 2 through the leak port 411. At this time, the moving distance of the seat frame 45 is S, and the final position of the seat frame 45 is A(0, Y 1, 0), where Y 1 = J + S ; S8. The angle meter in the arch seat 75 measures the rotation angle of the double-limb arch rib module 7 in real time. When it rotates 5° each time, measure the position information of the rotating hinge seat 74 through the second positioner 79. The position of the rotating hinge seat 74 is C( X 3, Y 3, Z3) The distance between points AC when the double-limbed arch rib module 7 is rotated at a 0° angle is used as a reference position for comparison. When the distance AC changes, it indicates that the double-limbed arch rib module 7 has deformed in the X / Y axis direction. ; in, X 3 is the value of the X axis of the rotating dumpling seat 74 in the coordinate system XOYZ; Y 3 is the value of the Y axis of the rotating dumpling seat 74 in the coordinate system XOYZ; Z 3 is the value of the Z axis of the rotating dumpling seat 74 in the coordinate system XOYZ; S9, determine the distance between the tensioning seat 53 and the rotating seat 74 and compare it with the length K of the rotating cable 54. If the two are inconsistent, it indicates that the double-limb arch rib module 7 has deformed in the Y / Z axis direction; Tensioning seat 53 position information B ( X 2,0 , Z 2), ; in, X 2 is the distance between the tower module 5 and the coordinate origin O, and the distance between the first group of tower modules 5 and the coordinate origin O is 1 / 3 of the span D of the double-limb arch rib module 7, and the distance between the second group of tower modules 5 and the coordinate origin O is 2 / 3 of the span D of the double-limb arch rib module 7, that is, the distance between the two arch seats 75 at the bottom is D; Z 2 is the height difference between the tensioning seat 53 and the tower base 51 in the tower module 5, and the height difference between the tensioning seat 53 and the tower base 51 in the two groups of tower modules 5 is the same; When deformation occurs, the device operation is stopped and the operator confirms on site whether the operation can continue; S10. When S9 is completed without any problems, the arch seat 75 is finally transferred to the seat frame 45. The operator fixes the double-limb arch rib module 7 to the mounting pier 2 through an external device, and finally restores the device to its original position.
