Description

Technical Field

[0001] The present application relates to the technical field of bridge construction, and in particular to a method for positioning an inclined embedded plate and a positioning device thereof. Background Art

[0002] In arch bridge construction, spatially tilted embedded slabs generally include arch seat embedded slabs embedded at the arch foot and bridge bearing slabs with longitudinal and transverse slopes. The arch rib embedded slabs of a basket arch bridge are tilted in multiple directions, while the arch seat embedded slabs of parallel arch ribs are tilted in one direction. Spatially tilted embedded slabs are large, requiring high precision in three-dimensional positioning, especially in the four-corner elevation difference positioning. The arch seat embedded slabs and bridge bearing slabs must maintain a relative elevation difference of no more than 2mm at any corner point relative to the plane formed by the remaining corner points. Furthermore, because the spatially tilted embedded slabs are tilted, it is difficult to place prism rods at the four corner points, making plane alignment difficult, setting up a level rod, and making elevation measurement difficult.

[0003] In the related art, the positioning of the spatially inclined embedded plates of arch bridges is generally carried out by using the total station polar coordinate measurement + leveling method. The total station is placed on the known control points on the ground and the level is placed on the pier at the arch foot. The positioning measurement is carried out in conjunction with the prism rods, prisms and level rods installed on the four corners of the spatially inclined embedded plates of the arch bridge. However, it is difficult to place the prism rods at the four inclined corner points, and the plane alignment error is large. It is also difficult to set up the level rods at the four inclined corner points, and the elevation measurement error is large. The relative height difference error of the four inclined corner points is even greater. At the same time, because the plane and elevation positioning are mutually restricted, the process is complicated. In the related art, there is also a method of using an inclinometer or an inclinometer to measure the relative height difference of the four inclined corner points. However, the measurement error of the inclinometer or the inclinometer is large, and it is difficult to meet the accuracy requirement of the arch seat embedded plates and the bridge support plates that the relative height difference of any corner point relative to the plane composed of the other corner points is not greater than 2mm. It can be seen that the traditional positioning measurement method has the defects of large positioning error and low accuracy, and is in urgent need of improvement. Summary of the Invention

[0054] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] The embodiments of the present application provide a method for positioning an inclined embedded plate and a positioning device thereof, which can solve the problems of large positioning errors and low precision in traditional positioning measurement methods in related technologies.

The inventive concept is to make full use of the prism component 3, the second auxiliary component 2 and the first auxiliary component 1 of the positioning device to transform the spatial inclined positioning of the inclined embedded plate 4 into plane positioning. The positioning device is used to measure the reference projection sliding height of the four corner points of the inclined embedded plate 4. The plane position of the inclined embedded plate 4 and the elevation of one corner are first adjusted to be precisely positioned, and then the elevations of the other corners are precisely positioned, thereby solving the problem of precise positioning of the inclined embedded plate 4 in the narrow bridge space and achieving high positioning accuracy.

[0057] See also Figure 1 As shown, in a first aspect, an embodiment of the present application provides a method for positioning an inclined embedded plate, which includes:

[0058] 101: Initially place the inclined embedded plate 4 in place, and set the prism assembly 3 and the second auxiliary assembly 2 at the corner points on both sides of any top edge of the inclined embedded plate 4. The second auxiliary assembly 2 is set on the inclined embedded plate 4, and the prism assembly 3 is connected to the top of the second auxiliary assembly 2;

[0059] 102: Use the prism assembly 3 and the second auxiliary assembly 2 to adjust the top edge to the plane design position, and adjust the corner point on any side of the top edge to the elevation design position, and use the point as the installation reference point;

[0060] 103: Arrange a second auxiliary component 2 on both sides of the other opposite top edge of the inclined embedded plate 4;

[0061] 104: Using the designed projected sliding height of any corner point on the top surface of the inclined embedded plate 4 as the reference projected sliding height of the corner point, and based on the reference projected sliding height and the structural parameters of the second auxiliary component 2, obtaining the reference projected sliding heights corresponding to the remaining corner points on the top surface of the inclined embedded plate 4;

[0062] 105: Install the first auxiliary component 1 on the second auxiliary component 2 at the four corner points of the inclined embedded plate 4, and adjust the position of the second auxiliary component 2 at the remaining corner points based on the reference projection sliding height of the installation reference point, so that the projection sliding height corresponding to each corner point is adjusted to its corresponding reference projection sliding height, completing the elevation position positioning of the remaining corner points.

[0063] In some embodiments, the positioning device includes a prism component 3 , a second auxiliary component 2 and a first auxiliary component 1 .

[0064] The second auxiliary component 2 is mounted on the inclined embedded plate 4, the prism component 3 is connected to the top of the second auxiliary component 2, and the first auxiliary component 1 is connected to the top of the second auxiliary component 2. When the positioning device is in use, the prism component 3 and the first auxiliary component 1 are respectively connected to the top of the second auxiliary component 2. In other words, when the positioning device is in use, either the prism component 3 is connected to the top of the second auxiliary component 2, or the first auxiliary component 1 is connected to the top of the second auxiliary component 2.

[0065] Furthermore, the first auxiliary component 1 includes: a positioning body 10, three connecting sleeves 11, a scale 13 and a sliding ruler 12, and the three connecting sleeves 11 are respectively arranged on the three surfaces of the positioning body 10; the scale 13 is arranged on one of the connecting sleeves 11 and is connected to the second auxiliary component 2; among the three connecting sleeves 11, the other two connecting sleeves 11 are provided with sliding rulers 12.

[0066] For details, see Figure 3 As shown, the positioning body 10 is a mounting platform for three connecting sleeves 11. Its shape can be a cuboid, cube, sphere, or other shapes. In this embodiment, the positioning body 10 is preferably a cube. A vertical tube 14 is mounted in the center of the positioning body 10, with the axis of the vertical tube 14 aligning with the axis of the cube. A bearing 15 is fixedly connected to the outer wall of the vertical tube 14. The outer wall of the bearing 15 is fixedly connected to the positioning body 10, allowing the positioning body 10 to rotate about the axis of the vertical tube 14.

[0067] The outer cross-sectional dimensions of the three connecting sleeves 11 are the same as the outer cross-sectional dimensions of a positioning body 10, and the hollow inner cross-sectional dimensions of the three connecting sleeves 11 are the same. Two horizontally arranged connecting sleeves 11 are perpendicular to each other and fixedly connected to the positioning body 10; another connecting sleeve 11 is vertically arranged and connected to the second auxiliary component 2. The top of the connecting sleeve 11 has a cylinder that coincides with its axis. The cylinder is embedded in the vertical pipe 14 of the positioning body 10 and is fixedly connected to the vertical pipe 14.

[0068] A sliding level 16 is also provided between the connecting sleeves 11 of two adjacent first auxiliary components 1, see Figure 6 As shown, a through hole 27 is formed in the middle of the sliding level 16, which is slidably connected to the sliding scale 12 on the connecting sleeve 11. The sliding level 16 is a hollow rectangular parallelepiped, with its outer cross-sectional dimensions identical to those of the horizontally disposed connecting sleeve 11 and its hollow inner cross-sectional dimensions matching those of the horizontally disposed sliding scale 12. Its ends can be respectively inserted into the sliding scales 12 of the two first auxiliary assemblies 1, allowing it to slide and extend along the sliding scales 12. A level is attached to the sliding level 16 for leveling. The three connecting sleeves 11 form a single unit, and two of them, along with the horizontally disposed connecting sleeve 11, can rotate vertically around the connecting sleeve 11 connected to the second auxiliary assembly 2.

[0069] Two rectangular slide rulers 12 and one rectangular scale 13 have outer cross-sectional dimensions identical to the inner cross-sectional dimensions of the hollow cores of the three connecting sleeves 11. The two slide rulers 12 and one scale 13 are respectively inserted into the inner hollow cores of the three connecting sleeves 11 and fixedly connected to the three connecting sleeves 11. The scale 13 has a scale marking and is mated with the second auxiliary assembly 2. The first auxiliary assembly 1 cooperates with the second auxiliary assembly 2 to establish the projected horizontal plane 5 of the inclined embedded plate 4.

[0070] Furthermore, the second auxiliary component 2 includes a sliding prism rod 23 and a loose-leaf member.

[0071] Specifically, the sliding prism rod 23 includes a plurality of connecting rods with tenon joints. A hollow core is provided at the top of the connecting rod at the top, and a through hole 27 is provided on the connecting rod at the bottom.

[0072] The sliding prism rod 23 is composed of multiple connecting rods connected by mortise and tenon joints. Its length is determined based on the projected elevation of the projected horizontal plane 5, the sliding height of the scale 13 of the first auxiliary assembly 1, and the elevation of each corner point of the inclined embedded plate 4. The sliding prism rod 23 is a hollow rectangular parallelepiped. Its outer cross-sectional dimensions are identical to those of the vertically mounted connecting sleeve 11 of the first auxiliary assembly 1. The inner cross-sectional dimensions of its hollow core match the outer dimensions of the scale 13 of the first auxiliary assembly 1. The top end of the top section of the sliding prism rod 23 can be inserted into the scale 13 of the first auxiliary assembly 1, allowing it to slide and retract along the scale 13 of the first auxiliary assembly 1 to adjust the vertical sliding length of the sliding prism rod 23.

[0073] The bottom end of the bottom section of the sliding prism rod 23 is provided with a through hole 27. The inner wall of the through hole 27 is provided with a threaded groove that mates with the loose-leaf shaft 21 in the loose-leaf member, used to secure the outer wall of the sliding prism rod 23 to the corner of the inclined embedded plate 4. The top section of the sliding prism rod 23 is provided with a fixing screw 28, used to fix the sliding prism rod 23 after it is slid and extended along the scale 13 of the first auxiliary assembly 1. The middle portion of the sliding prism rod 23 is hingedly connected to two support bodies 29 via hinge screws 293. The support bodies 29 include a support rod 291 hinged to the sliding prism rod 23. The bottom end of the support rod 291 is provided with a universal hinged magnetic block 290, which allows the support rod 291 to be extended and rotated with friction braking. In conjunction with the circular level 292 on the sliding prism rod 23, it is used to keep the sliding prism rod 23 plumb vertically.

[0074] The movable member includes a movable shaft 21, which is penetrated by a through hole 27 and connected to the sliding prism rod 23. The movable shaft 21 has movable pieces 24 hinged on both sides. The movable pieces 24 are provided with fixing parts for fixing to the inclined embedded plate 4.

[0075] The specific loose-leaf parts are composed of two loose-leaf pieces 24, two magnets 25 with magnetic switches, a loose-leaf shaft 21 and a fastening screw 26. The two magnets 25 with magnetic switches are respectively fixed on the two loose-leaf pieces 24, and are used to magnetically attract the two loose-leaf pieces 24 to the top and side surfaces at the corner points of the inclined embedded plate 4, so that one end of the two loose-leaf pieces 24 is aligned with the corner points of the inclined embedded plate 4. The loose-leaf shaft 21 is installed in the middle of the two loose-leaf pieces 24. The loose-leaf shaft 21 extends outward into a screw rod 22 at the corner points of the inclined embedded plate 4, and cooperates with the fastening screw 26 to fasten the outer wall of the sliding prism rod 23 hinged on the screw rod 22 of the loose-leaf shaft 21 to the corner points of the inclined embedded plate 4, wherein the specifications and dimensions of each magnetic loose-leaf shaft 21 are the same.

[0076] Based on the above embodiment, in this embodiment, the prism assembly 3 includes: a joint 31, a tray 30, a prism boss 32 and a prism body 33, the joint 31 is connected to the second auxiliary component 2; the tray 30 is fixed on the joint 31; the prism boss 32 is arranged at the center of one side edge of the top surface of the tray 30; and the prism body 33 is arranged on the prism boss 32.

[0077] Specifically, the tray 30 is square, and the outer dimensions of the tray 30 are the same as the outer dimensions of the sliding prism rod 23. The joint 31 is a rectangular parallelepiped. The joint 31 is fixed at the center of the bottom surface of the tray 30. Its outer cross-sectional dimensions match the hollow inner cross-sectional dimensions of the sliding prism rod 23 and can be inserted into the sliding prism rod 23. The prism boss 32 is set at the center of one side of the top surface of the tray 30. After the prism assembly 3 is inserted into the sliding prism rod 23, its prism boss 32 is on the center line of the outer wall of the sliding prism rod 23. The prism body 33 is installed on the prism boss 32 for measuring the three-dimensional coordinates of each corner of the inclined embedded plate 4 to be installed.

[0078] On this basis, the inclined embedded plate 4 is initially put in place, and the prism assembly 3 and the second auxiliary assembly 2 are set at the corner points on both sides of any top edge of the inclined embedded plate 4, specifically including steps 1011 to 1014:

[0079] Step 1011: Put the inclined embedded plate 4 into initial position.

[0080] Specifically, the inclined embedded plate 4 is placed at a set position to complete the initial positioning of the inclined embedded plate 4.

[0081] Step 1012: Fix the two loose-leaf pieces at the corner points on both sides of any top edge of the inclined embedded plate 4 respectively.

[0082] For details, see Figure 2 As shown, to facilitate subsequent positioning of a corner point, two magnetic hinge shafts 21 are magnetically attached to the lowest and second lowest points B and C of the embedded plate 4 to be tilted, respectively, so that one end of the two hinge pieces 24 is aligned with the two corners B and C of the BC side of the tilted embedded plate 4. Selecting a corner point at a low position for operation makes it easier to use support tools to position and support the corner point.

[0083] It should be noted that the corner points B, C, A, and D here are respectively the four corners on the top surface of the inclined embedded plate 4.

[0084] Step 1013: Install the two sliding prism rods 23 on the two loose-leaf shafts 21 respectively.

[0085] Specifically, the two sliding prism rods 23 are respectively installed on the screw rods 22 of the two magnetic hinge shafts 21, and the universal hinged magnetic blocks 290 of the two support rods 291 of the two sliding prism rods 23 are respectively magnetically attracted to the top surface of the inclined embedded plate 4.

[0086] Step 1014 : Install the joints 31 of the two prism assemblies 3 on the two sliding prism rods 23 respectively, and make the prism boss 32 on the tray 30 coaxial with the central axis of the outer side wall of the sliding prism rod 23 .

[0087] Specifically, the connectors 31 of the two prism assemblies 3 are inserted into the two sliding prism rods 23, respectively, and the prism bosses 32 on the tray 30 are aligned with the central axis of the outer wall of the sliding prism rod 23, which is in close contact with the corners B and C of the inclined embedded plate 4. The two support rods 291 of each sliding prism rod 23 are used with their circular levels 292. The two sliding prism rods 23 are adjusted to make them plumb vertical, and the support rods 291 are hingedly fastened to the sliding prism rods 23 using the hinge screws 293. Then, the fastening screws 26 of the hinge shaft 21 are tightened, and the outer walls of the two sliding prism rods 23 are respectively in close contact with the two corners B and C on the bottom edge of the inclined embedded plate 4.

[0088] The two prism bodies 33 are respectively installed on the prism protrusion 32 of the outer wall of the sliding prism rod 23, which is closely attached to the two corners B and C of the bottom edge of the inclined embedded plate 4, that is, on the plumb projection points of the two corners B and C of the BC edge of the inclined embedded plate 4.

[0089] Based on the above embodiment, in this embodiment, the prism assembly 3 and the second auxiliary assembly 2 are used to adjust the top edge to the plane design position, and the corner point on any side of the top edge is adjusted to the elevation design position, and the point is used as the installation reference point. The specific steps include steps 1021 to 1023:

[0090] Step 1021: Using a measuring instrument, measure the actual three-dimensional coordinates of the corner points on both sides of the top edge, where the actual three-dimensional coordinates include actual plane coordinates and actual elevation coordinates;

[0091] Specifically, in this embodiment, a total station is used to measure the actual three-dimensional coordinates (X-axis, Y-axis, Z-axis) of the centers of the two prism bodies 33 respectively, so that the actual plane coordinates of the two corners B and C of the inclined embedded plate 4BC and the actual elevation coordinates of the centers of the two prism bodies 33 can be obtained.

[0092] In addition, in order to improve the accuracy of the measurement, the actual plane coordinates of the centers of the two prism bodies 33 can be measured separately using a total station, and then the sliding prism rod 23 placed at the lowest angle C of the inclined embedded plate 4 (angle C is selected as the installation reference point in this embodiment) is readjusted to the vertical position of the plumb bob and fastened by the hinge screw 293 and the fastening screw 26, according to the actual elevation coordinates of the center of the prism body 33 measured by the total station.

[0093] According to the actual elevation coordinates of the center of the prism body 33, the known height from the center of the prism body 33 to the bottom point of the screw rod 22 of the corresponding magnetic hinge shaft 21, and the thickness of the hinge 24, the elevation of the angle C, i.e., the actual elevation coordinates, can be obtained.

[0094] Step 1022: Based on the plane deviations between the actual plane coordinates and the theoretical plane coordinates of the corner points on both sides of the top edge, the corner points on both sides are adjusted to the plane design positions, so that the top edge is adjusted to the plane design position.

[0095] Specifically, the plane deviations of the plane coordinates of the two corners B and C of the inclined embedded plate 4BC and their corresponding theoretical plane coordinates are compared. According to the plane deviation, the jack cooperates with the positioning baffle component set at the edge of the inclined embedded plate 4BC to adjust the edge of the inclined embedded plate 4BC so that it is in place in the plane position.

[0096] Step 1023: Based on the elevation deviation between the actual elevation coordinates of the corner point on any side of the top edge and the theoretical elevation coordinates, adjust the corner point to the elevation design position.

According to the elevation deviation, the lifting equipment cooperates with the lifting component set at the lowest corner C of the inclined embedded plate 4 to adjust the elevation of the lowest corner C of the inclined embedded plate 4 to precisely position it.

[0098] On the basis of the above embodiment, in this embodiment, second auxiliary components 2 are set on both sides of the other opposite top edge of the inclined embedded plate 4, and the second auxiliary components 2 are installed on all corner points of the top of the inclined embedded plate 4 according to the above installation method.

[0099] On the basis of the above embodiment, in this embodiment, the designed projected sliding height of any corner point on the top surface of the inclined embedded plate 4 is used as the reference projected sliding height of the corner point, and based on the reference projected sliding height and the structural parameters of the second auxiliary component 2, the reference projected sliding heights corresponding to the remaining corner points on the top surface of the inclined embedded plate 4 are obtained, specifically including steps 1041 to 1044:

[0100] Step 1041: The designed projected sliding height of any corner point on the top surface of the inclined embedded plate 4 is used as the reference projected sliding height L of the corner point.投A , based on the first design distance L between the corner point and the top of the second auxiliary component 2 A , the reference projection sliding height L of the corner point 投A , get the second design distance L at the corner point Aa The second design distance is the distance between the corner point and the top of the first auxiliary component 1 after the first auxiliary component 1 is installed on the second auxiliary component 2.

[0101] In this embodiment, the angle A on the top surface of the inclined embedded plate 4 is used as a reference object.

[0102] Specifically, considering that after the inclined embedded plate 4 is initially in place, the actual elevation of angle A is different from its design theoretical elevation H A The deviation is no more than 5 cm, so a 0.05 m projection sliding height is reserved, which is the reference projection sliding height L of angle A. 投A =0.05 meters.

[0103] The known height from the center of the screw rod 22 of the hinged shaft 21 at the corner A of the inclined embedded plate 4 to the top surface of the sliding prism rod 23, that is, the first design distance is L A At the same time, the connecting sleeve 11 of the positioning body 10 is known to be L 套 The known radius of the screw rod 22 of the loose-leaf shaft 21 is R, and the known thickness of the loose-leaf sheet 24 is L. 片 Then tilt the embedded plate 4 corner A to the first auxiliary component 1 and insert the sliding prism rod 23. When the scale 13 reserves 0.05 meters for the adjustment height, the height L of the top surface a of the positioning body 10 is Aa for:

[0104] L Aa =L A +L 套 +L 投A +R+L 片 =L A +L 套 +0.05+R+L 片 ;

[0105] Step 1042: Based on the second design distance and the design theoretical elevation of the corner point, obtain the projection elevation of the inclined embedded plate 4.

[0106] The design theoretical elevation of this corner point is H A , the projection elevation H of the inclined embedded plate 4 投 for:

[0107] H 投 =H A +L Aa =H A +(L A +L 套 +0.05+R+L片 ).

[0108] Step 1043: Based on the projection elevation and the design theoretical elevations of the remaining corner points, obtain the second design distances of the remaining corner points.

[0109] According to the other three corners B, C, and D of the inclined embedded plate 4, the theoretical height H is designed. B 、H C 、H D and the projected elevation H 投 Calculate the height L of the other three corners B, C, and D from the top surface of the positioning body 10 Bb =H 投 -H B , L Cc =H 投 -H C , L Dd =H 投 -H D .

[0110] It should be noted that the sliding prism rod 23 is divided into different types of rods, such as a long rod and a short rod, and each different type of sliding prism rod 23 corresponds to a standard length.

[0111] After calculating the heights of the other three corners B, C, and D from the top surface of the positioning body 10, the matching standard length L of each sliding prism rod 23 is selected accordingly. B , L C , L D , and reserve a sliding adjustment length interval for the scale 13.

[0112] Step 1044: Based on the second design distances of the remaining corner points, the structural parameters of the second auxiliary component 2 and the structural parameters of the first auxiliary component 1, obtain the reference projection sliding heights corresponding to the remaining corner points.

[0113] Specifically, according to the known height L from the other three corners B, C, and D of the inclined embedded plate 4 to the top surface of its positioning body 10 Bb , L Cc , L Dd , the known matching length L of each sliding prism rod 23 B , L C , L D The height of the connecting sleeve 11 of the positioning body 10 is known to be L 套 , the radius R of the screw rod 22 of the loose-leaf shaft 21 and the thickness L of the loose-leaf piece 24 片 , calculate the reference projection sliding height L of each scale 13 at the other three corners B, C, and D of the inclined embedded plate 4 投B =L Bb -L B -L 套 -RL片 , L 投C =L Cc -L C -L 套 -RL 片 , L 投D =L Dd -L D -L 套 -RL 片 .

[0114] Based on the above embodiment, in this embodiment, the first auxiliary component 1 is installed on the second auxiliary component 2 at the four corner points of the inclined embedded plate 4, and based on the reference projected sliding height of the installation reference point, the position of the second auxiliary component 2 at the remaining corner points is adjusted so that the projected sliding height corresponding to each corner point is adjusted to its corresponding reference projected sliding height, thereby completing the elevation position positioning of the remaining corner points. Specifically, the steps 1051 to 1055 are as follows:

[0115] Step 1051: Install the first auxiliary component 1 on the second auxiliary component 2 at the installation reference point based on the reference projected sliding height of the installation reference point.

[0116] Specifically, the four magnetic hinge shafts 21 are magnetically attracted to the corners A, B, C, and D of the bottom edge of the inclined embedded plate 4 again, so that one end of each of the two hinge pieces 24 is aligned with the corners A, B, C, and D of the inclined embedded plate 4 respectively;

[0117] Then check the installation and positioning of the second auxiliary component 2 at corner C, install the sliding prism rod 23 that matches the angle C of the inclined embedded plate 4, which has been adjusted to a precise position, on the screw rod 22 of its corresponding magnetic loose-leaf shaft 21, and magnetically attract the universal hinged magnetic blocks 290 of its two support rods 291 to the top surface of the inclined embedded plate 4 respectively. Insert the scale 13 of the first auxiliary component 1 into the sliding prism rod 23 to its projected sliding height L 投C The two support rods 291 of the sliding prism rod 23 cooperate with its circular level 292 to adjust the sliding prism rod 23 to be vertical, tighten the fastening screws 26 of the loose-leaf shaft 21 respectively, and attach the outer wall of the sliding prism rod 23 to the corner C point of the inclined embedded plate 4.

[0118] Step 1052: Install the first auxiliary components 1 on the second auxiliary components 2 at the remaining corner points, and connect two adjacent first auxiliary components 1.

[0119] Step 1053: Adjust the first auxiliary component 1 to a horizontal setting, and obtain the actual projected sliding heights of the remaining corner points at this time.

[0120] Specifically, the sliding prism rod 23 that matches the second lowest angle B adjacent to the lowest angle C of the inclined embedded plate 4 whose elevation has been adjusted and precisely positioned is installed on the screw rod 22 of the magnetic loose-leaf shaft 21 of the second lowest angle B of the inclined embedded plate 4, and the universal hinged magnetic blocks 290 of the two supporting rods 291 of the sliding prism rod 23 are respectively magnetically attracted to the top surface of the inclined embedded plate 4, and the scale 13 of the first auxiliary component 1 is inserted into the sliding prism rod 23 at the second lowest angle B of the inclined embedded plate 4, and the two supporting rods 291 of the sliding prism rod 23 at the second lowest angle B of the inclined embedded plate 4 cooperate with its circular level 292 to adjust the sliding prism rod 23 to be plumb vertical. Tighten the fastening screws 26 of the hinge shaft 21 and place the outer wall of the sliding prism rod 23 against the fourth lowest corner point B of the inclined embedded plate. Insert one end of a sliding level 16 into the sliding level 12 of the first auxiliary component 1 at the lowest corner point C of the inclined embedded plate 4. Slide the other end of the sliding level 16 back into the sliding level 12 of the first auxiliary component 1 at the fourth lowest corner point B of the inclined embedded plate.

[0121] Then adjust the scale 13 of the first auxiliary component 1 at the second lowest angle B of the inclined embedded plate 4 so that the level bubble of the level tube with the two ends inserted into the sliding level 16 of the first auxiliary component 1 at the lowest angle C and the second lowest angle B of the inclined embedded plate 4 is centered, and read the engraved reading of the scale 13 of the first auxiliary component 1 at the second lowest angle B of the inclined embedded plate 4, which is the actual projected sliding height L 读B ;

[0122] Repeat the above steps to obtain the actual projected sliding heights of the four highest angles D and the highest angle A of the inclined embedded plate in sequence.

[0123] Step 1054: Based on the actual projected sliding heights of the remaining corner points and the reference projected sliding heights, obtain the sliding height deviations of the remaining corner points.

[0124] Read the scale 13 of the first auxiliary component 1 at the 4th low angle B point of the inclined embedded plate, which is the actual projected sliding height L 读B , and its reference projection sliding height L 投B By comparison, the sliding height deviation L of the scale 13 at the second lowest angle B is obtained. 投B -L 读B Repeat the above steps to obtain the sliding height deviations of the four highest angles D and the highest angle A of the inclined embedded plate in sequence.

[0125] Step 1055: Based on the sliding height deviation of the remaining corner points, adjust the elevation positions of the remaining corner points and the position of the second auxiliary component 2, so that the projection sliding height corresponding to each corner point is adjusted to its corresponding reference projection sliding height, and complete the elevation position positioning of the remaining corner points.

[0127] First, based on the sliding height deviations of the remaining corner points, adjust the elevation positions of the remaining corner points and the position of the second auxiliary component 2 to complete the preliminary positioning of the remaining corner points:

[0128] First, according to the sliding height deviation L of the scale 13 at the second lowest angle B point 投B -L 读B , the hoisting equipment cooperates with the lifting component set at the 4th low angle B of the inclined embedded plate to adjust the elevation of the 4th low angle B of the inclined embedded plate in the installation space to preliminarily position it. Then adjust the elevation of the 4th high angle D and the highest angle A of the inclined embedded plate in sequence to preliminarily position them.

[0129] Then adjust the second auxiliary component 2 at the remaining corner points again to keep the second auxiliary component 2 vertical: considering that the sliding prism rod 23 of the inclined embedded plate 4 is tilted due to the initial positioning of the elevation of the 4th low angle B of the inclined embedded plate, adjust the sliding prism rod 23 of the inclined embedded plate 4 to be plumb vertical again.

[0130] Adjust the first auxiliary component 1 to a horizontal setting again, and obtain the actual projected sliding heights of the remaining corner points at this time. Repeat the adjustment of the scale 13 to center the bubbles of the spirit level tubes inserted at both ends of the sliding level 16 of the first auxiliary component 1, and obtain the actual projected sliding heights of the remaining corner points at this time. Finally, based on the sliding height deviations of the remaining corner points, adjust the elevation positions of the remaining corner points and the position of the second auxiliary component 2 again, so that the corresponding projected sliding height of each corner point is adjusted to its corresponding reference projected sliding height, completing the elevation positioning of the remaining corner points.

[0131] It should also be noted that: based on the lowest angle C of the inclined embedded plate 4 that has been adjusted in height and precisely positioned, the sliding height deviation L of the scale 13 at the highest angle A is adjusted from the second lowest angle B and the second highest angle D of the inclined embedded plate 4. 投A -L 读B =0.05-L 读B When the deviation is greater than the allowable installation deviation of the inclined embedded plate 4, insert the two ends of the sliding level 16 into the sliding ruler 12 of the first auxiliary component 1 at the second lowest angle B and the highest angle A of the inclined embedded plate 4. The sliding height deviation L of the scale 13 at the highest angle A 投A -L 读B =0.05-L 读BEvenly distribute the elevations of the 4th lowest angle B, the second highest angle D, and the highest angle A of the inclined embedded plate. The hoisting equipment cooperates with the lifting components set at the 4th lowest angle B, the second highest angle D, and the highest angle A of the inclined embedded plate to make the four sliding level rulers 16 installed between A, B, C, and D level and consistent. At this time, the sliding height deviation of the scale ruler 13 at the highest angle A is L 投A -L 读B =0.05-L 读B The average has been distributed to the elevations of the 4th lowest angle B, the second highest angle D and the highest angle A of the inclined embedded plate. At this point, the precise positioning of the inclined embedded plate 4 in the space to be installed is completed.

[0132] In summary, the present application makes full use of the positioning device, transforms the spatial tilt positioning into plane positioning, and uses a level ruler to accurately measure the relative height difference of the four corner points of the spatial tilt embedded plate 4, thereby solving the problem of precise positioning of the spatial tilt embedded plate 4 of the narrow bridge, so the positioning accuracy is high;
