[0018] In a second aspect, the present invention provides a method for using the detection device based on the integral lateral rotation of the primary and secondary double-limb arch ribs according to the first aspect, comprising the following steps:

[0019] S1. Build a double-limb arch rib module in advance according to the requirements of bridge construction, and the span of the double-limb arch rib module is D. Adjust the lengths of the first transverse telescopic frame and the second transverse telescopic frame of the telescopic fixed grid module according to the span information of the double-limb arch rib module;

[0020] S2. Link and secure the four transversely movable detection frame modules and the two sets of tower modules together. Then, place the two sets of double-limb arch rib modules into the four transversely movable detection frame modules. Hook the swivel cable onto the swivel capstan. Extend the swivel cable out of the swivel capstan. Measure the extended length of the cable using a detector inside the cable. The extended length is K.

[0021] S3. Install the four first positioners to the middle position inside the mounting pier, and install the second positioner to the turning base;

[0022] S4. The first positioner measures the height position information of the installation pier seat, and adjusts the installation pier seat, the detection control seat module, the transversely movable detection frame module and the tower module to the same height through the mobile module, and sets the corresponding group of detection control seat modules in a group of controllers as the coordinate origin O. The direction of the connection between the detection control seat module as the coordinate origin and the other group of detection control seat modules is the X-axis, the direction of the connection between the two groups of transversely movable detection frame modules on the side of the detection control seat module as the coordinate origin is the Y-axis, and the vertical direction is the Z-axis, thereby forming a coordinate system XOYZ;

[0023] S5. The controller automatically controls the device to start moving. The four first positioners transmit their position information to the controller in real time for analysis. The four first positioners are arranged in pairs symmetrically along the length of the bridge toward the middle line. The control device moves to the center position, i.e., the distance between the first positioners in a group and the detection and control seat module is equal. When the detection and control seat module is flush with the first positioners, the device stops moving.

[0024] S6. Lower the stable detection L-base and the tower stable L-base, and fix the detection control base module and the tower module using the first fixing bolt and the sixth fixing bolt;

[0025] S7. The distance between the positioning module in the bottom seat frame of the double-limb arch rib module and the coordinate origin O is J. The horizontal moving detection frame module is symmetrically extended to move the leak frame to the installation pier seat, and the frame is also extended and pushed to the leak, and falls through the leak to the installation pier seat. At this time, the movement distance of the frame is S, and the final position of the frame is A (0, Y 1,0), where Y 1= J + S ;

[0026] S8, the angle meter in the arch seat measures the rotation angle of the double-limb arch rib module in real time, and the position information of the turning seat is measured by the second positioner every 5° rotation. The position C( X 3, Y 3, Z 3) The distance between points AC when the double-limbed arch rib module rotates at a 0° angle is used as the reference position for comparison. When the AC distance changes, it indicates that the double-limbed arch rib module has deformed in the X / Y axis direction.

[0027] ;

[0028] in, X 3 is the value of the X axis of the turning seat (74) in the coordinate system XOYZ;

[0029] Y 3 is the value of the Y axis of the turning seat (74) in the coordinate system XOYZ;

[0030] Z 3 is the value of the Z axis of the turning seat (74) in the coordinate system XOYZ;

[0031] S9. Determine the distance between the tensioning seat and the turning seat and compare it with the length of the turning cable. If the two are inconsistent, it indicates that the double-limb arch rib module has deformed in the Y / Z axis direction.

[0032] Tensioning seat 53 position information B ( X 2,0 , Z 2),

[0033] ;

[0034] 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;

[0035] 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;

[0036] When deformation occurs, the device operation is stopped and the operator confirms on site whether the operation can continue;

[0037] S10. When S9 is no problem, the arch seat is finally transferred to the seat frame. The operator fixes the double-limb arch rib module to the installation pier seat through an external device, and finally restores the device to its original position.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. The operation method provided by the present invention is different from the traditional process. The two ends of the arch foot swivel shaft are used as the rotation axis, and the arch ribs assembled in a flat state are rotated sideways to the installation position. Compared with the installation method of cable hoisting construction, side rotation can greatly reduce the content and time of high-altitude work, and transfer most of the high-altitude splicing and welding work content to the assembly plane operation. Compared with the traditional beam-first and arch-later hoisting method, side rotation only requires fewer temporary facilities to maintain the arch rib installation system. The side rotation construction method can complete the installation and construction of the arch rib structure with lower safety risks, shorter construction period and lower maintenance cost.

[0040] 2. The present invention automatically adjusts the movement of the control device through the first positioner, which facilitates the installation process. During the side rotation process, the distance information between the capstan seat and the arch seat and the capstan seat and the tensioning seat is analyzed to determine whether the capstan seat in the direct force position is deformed to determine the status of the double-limb arch rib module.

The position C ( X 3, Y 3, Z 3), and the distance between points AC when the double-limb arch rib module 7 rotates at an angle of 0° is used as the comparison reference position, When the AC distance changes, it indicates that the double-limbed arch rib module 7 has deformed in the X / Y axis direction. If the subsequent detection angle AC distance is less than the reference position AC distance, the double-limbed arch rib module 7 deflects toward the coordinate origin O, otherwise it deflects away from the coordinate origin O. The distance between the tensioning seat 53 and the rotating seat 74 is compared with the length K of the rotating cable 54. If the two are inconsistent, it indicates that the double-limbed arch rib module 7 has deformed in the Y / Z axis direction. The position information B of the tensioning seat 53 ( X 2,0 , Z 2), When K>BC distance, the double-limb arch rib module 7 deviates in the direction away from the tower module 5.

[0075] Working principle:

[0076] Before construction, the double-limb arch rib module 7 is constructed in advance according to the construction requirements of the bridge 1, and the span of the double-limb 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 frame module 6 are adjusted according to the span information of the double-limb arch rib module 7. The first fixed block 63 and the second fixed 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 fixed block 67 and the fourth fixed block 68 are inserted into the transverse movable seat 41 and fixed by the transverse movable clamping plate 48 and the fourth fixing bolt 481. In this way, the four transverse movable detection frame modules 4 and the tower module 5 are linked and fixed together.

[0077] Next, place the two groups of double-limb arch rib modules 7 into the four laterally movable detection frame modules 4, press the card seat shaft 78 to store the storage shaft 77 into the swivel shaft 76, and place the swivel shaft 76 at the bottom of the double-limb arch rib module 7 into the first swivel seat 451 through an external lifting device. After releasing the card seat shaft 78, the card seat shaft 78 is inserted into the first swivel seat 451 to fix the double-limb arch rib module 7 to the seat frame 45. After inserting the two groups of separate slides 46 into the slide rails 44, fix them to the seat frame 45 through the third fixing bolt 461, and then hook the swivel rope 54 to the swivel seat 74. The swivel rope 54 extends out of the swivel seat 74, and the extended length is measured by the detector inside it. The extended length is K. At the same time, the four first positioners 9 are installed to the middle position inside the mounting pier 2, and the second positioner 79 is installed on the swivel seat 74.

[0078] Start the device, the first locator 9 measures the height position information of the installation pier 2, and adjusts the installation pier 2, the detection control seat module 3, the horizontal movement detection frame module 4 and the tower module 5 to the same height through the third telescopic frame 84 in the mobile module 8, and sets a group of detection control seat modules 3 as the coordinate origin O in the controller 37, the connection direction of the two groups of detection control seat modules 3 is the X-axis, the connection direction of the two groups of horizontal movement detection frame modules 4 at the front end is the Y-axis, and the vertical direction is the Z-axis.

[0079] Then, the controller 37 automatically controls the device to start moving, and the four first positioners 9 transmit position information to the controller 37 in real time for analysis. The four first positioners 9 are arranged in pairs as a group symmetrically along the length of the bridge 1 toward the middle line. The control device moves to the center position, that is, the first positioners 9 in a group are at the same distance from the detection control seat module 3. When the detection control seat module 3 is flush with the first positioner 9, the device stops moving, lowers the stable detection L seat 32 and the tower stable L seat 57, and fixes the detection control seat module 3 and the tower module 5 by the first fixing bolt 35 and the sixth fixing bolt 58.

[0080] The distance between the positioning module in the bottom seat frame 45 of the double-limb arch rib module 7 and the coordinate origin O is J, and the horizontal moving detection frame module 4 is symmetrically extended to set the leakage 411 on the installation pier seat 2, and the seat frame 45 is also extended and pushed to the leakage 411, and falls onto the installation pier seat 2 through the leakage 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 meter in the arch seat 75 measures the rotation angle of the double-limb arch rib module 7 in real time, and measures the position information of the hinge seat 74 through the second positioner 79 every 5° rotation. The position of the hinge seat 74 is C (Q, W, E), and the distance between points AC when the rotation angle of the double-limb arch rib module 7 is 0° is used as the comparison reference position.

[0081] When the AC distance changes, it means that the double-limb arch rib module 7 is deformed in the X / Y axis direction, and if the subsequent detection angle AC distance is less than the reference position AC distance, the double-limb arch rib module 7 deviates toward the coordinate origin O, otherwise it deviates away from the coordinate origin O.

[0082] 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 means that the double-limb arch rib module 7 has deformed in the Y / Z axis direction.

[0083] Tensioning seat 53 position information B ( X 2,0 , Z 2), When K>BC distance, the double-limb arch rib module 7 deviates in the direction away from the tower module 5.

[0084] When deformation occurs, the device operation is stopped and the operator confirms on site whether the operation can continue.

[0085] If there is no deformation problem, or the deformation problem is solved, the arch seat 75 is finally transferred to the seat frame 45, and the operator fixes the double-limb arch rib module 7 to the installation pier 2 through an external device, and finally restores the device to its original position.
