DETAILED DESCRIPTION

[0027] Example 1

[0028] As Figures 1-7As shown, a chute H-beam measuring installation device, the track 2 of the H-beam 1 is provided with at least one vertical rod 3, the vertical rod 3 is horizontally arranged, the lower end of the vertical rod 3 is arranged on the base 4, the base 4 is clamped on the track 2 of the H-beam 1, and the upper end of the vertical rod 3 is further provided with a GPS locator 6, and the GPS locator 6 is provided with a prism 7.

[0029] The vertical rod 3 is used as a carrier for measuring reference, which is horizontally arranged on the track 2 of the H-beam 1 and fixed in position through the base 4 at the lower end. The base 4 is clamped on the track 2, wherein the upper top plate 401 is rotationally connected with the lower end of the vertical rod 3, facilitating adjustment of the angle of the vertical rod 3, and the lower part is connected with the lower bottom plate 403 through a leveling device to ensure overall stability, and the clamping plate 404 of the lower bottom plate 403 forms a groove closely fitted with the track 2 and is fixed by being tightly abutted against the side of the track 2 through the first nut 405 on one side. The GPS locator 6 and the prism 7 are arranged at the upper end of the vertical rod 3. The GPS locator 6 is based on a satellite navigation system, measures the distance from the satellite through receiving satellite signals, and calculates the longitude, latitude and elevation information in the WGS-84 coordinate system combined with satellite orbit parameters and clock information, and then converts to the local coordinate system of the construction area to realize real-time monitoring and positioning of the position of the H-beam 1.

[0030] A reliable measuring reference is provided for the installation of the H-beam 1, and the position information of the H-beam 1 can be accurately obtained through the vertical rod 3 and the measuring device thereon. Compared with the traditional method, the installation is convenient and does not require large lifting equipment to assist in installing the base 4 and the vertical rod 3, effectively saving labor and time costs and improving construction efficiency. With the real-time positioning function of the GPS locator 6, the position of the H-beam 1 can be dynamically adjusted during hoisting and installation, ensuring installation accuracy, reducing construction errors caused by inaccurate positioning, and ensuring the smooth progress of the chute construction and the quality of the project.

[0031] In the preferred embodiment, the base 4 includes an upper top plate 401, the lower end of the vertical rod 3 is rotationally connected with the upper top plate 401, the lower top plate 401 is connected with the lower bottom plate 403 through a leveling device below, the lower bottom plate 403 is provided with a clamping plate 404, and the clamping plate 404 forms a groove clamped on the track 2. The first nut 405 passes through the clamping plate 404 and abuts against the side of the track 2, and is tightened to generate an inward pressure to make the clamping plate 404 fit the track 2.

[0032] In the preferred embodiment, the upper end of the upper plate 401 is provided with a plurality of first adjusting screws, and the upper end of the lower plate 403 is provided with a plurality of second adjusting nuts. The first adjusting screws and the second adjusting nuts are correspondingly arranged, and the first adjusting screws and the second adjusting nuts are connected through the adjusting nut 402. By rotating the adjusting nut 402, the upper plate 401 and the lower plate 403 can be finely adjusted to ensure that the vertical rod 3 and the end of the H-beam 1 are in a parallel state. The upper plate 401 and the lower plate 403 are connected through the adjusting structure composed of the first adjusting screw, the second adjusting nut and the adjusting nut 402. When the adjusting nut 402 is rotated, due to the transmission effect of the screw thread, the adjusting nut 402 will move along the screw thread direction of the first adjusting screw and the second adjusting nut, thereby changing the relative position relationship between the upper plate 401 and the lower plate 403. This change in relative position can finely adjust the angle of the vertical rod 3 fixed on the upper plate 401, so that the vertical rod 3 and the end of the H-beam 1 reach a parallel state. The principle is based on the mechanical principle of screw thread transmission, and by accurately controlling the rotation angle and displacement of the adjusting nut 402, the adjustment of the small angle deviation is realized.

[0033] In the preferred embodiment, one side of the clamping plate 404 is provided with a plurality of first nuts 405, and the first nuts 405 pass through the clamping plate 404 and abut against the side of the track 2, so as to fix the groove under the lower plate 403 on the track 2.

[0034] The groove composed of the clamping plate 404 cooperates with the track 2 of the H-beam 1, and a plurality of first nuts 405 are arranged on one side of the clamping plate 404. The screw thread structure of the nut is used. When the first nut 405 is tightened, the nut moves axially along the screw thread, generating an axial force that pushes the clamping plate 404 to tightly fit the side of the track 2, increases the friction between the clamping plate 404 and the track 2, and firmly fixes the groove under the lower plate 403 on the track 2 through mechanical extrusion, preventing displacement due to external forces during construction.

[0035] The stable installation of the base 4 on the track 2 of the H-beam 1 is realized, and the position stability of the measuring device on the H-beam 1 is ensured. In the construction environment of the H-beam slide in the shallow water area, the device may be disturbed by external forces such as water flow impact and construction vibration. This fixing method can effectively resist these external forces, ensure the continuity and accuracy of the measurement work, provide a reliable basis for subsequent measurement and installation operation, and reduce the measurement error and construction problems caused by displacement of the device.

[0036] In the preferred embodiment, the base 4 is provided with a positioning plate 5 on one side. The positioning plate 5 has a right-angle structure, with one end connected to the base 4 and the other end abutting against the end of the H-beam 1. The positioning plate 5 is mainly used to position the stand 3. When installing two stands 3, the positioning plate 5 can be used to adjust the distance between the two stands 3 and the end of the H-beam 1. The right-angle structure of the positioning plate 5 is rigidly connected to the base 4, ensuring the stability of the relative position. During installation, the inner side of the vertical rod at the other end of the positioning plate 5 abuts against the end of the H-beam 1, serving as a reference to determine the position of the stand 3. When installing multiple stands 3, the consistency of the positioning plate 5 and the relative stability of the end of the H-beam 1 ensure that the distance between each stand 3 and the end of the H-beam 1 remains the same, ensuring the standardization and consistency of the installation position of the stand 3.

[0037] This greatly improves the accuracy and uniformity of the installation position of the stand 3, simplifying the positioning operation during installation. Compared to the case without the positioning plate 5, the workload of manual measurement and adjustment is reduced, improving the construction efficiency. At the same time, the relative position accuracy of multiple stands 3 on the H-beam 1 is ensured, providing a stable and reliable foundation for subsequent measurement and installation work based on the stand 3, which is conducive to improving the quality of the entire H-beam installation project in the shallow water area.

[0038] In the preferred embodiment, the positioning plate 5 is fixed to the lower bottom plate 403 by multiple second nuts 406 at one end. The corner of the positioning plate 5 is also provided with a positioning surface 501 that abuts against the upper surface of the H-beam 1. After the construction of the H-beam 1 is completed, the positioning surface 501 ensures that the upper surface of the positioning plate 5 is in a horizontal state, and also positions the vertical state of the stand 3. The positioning plate 5 is fixed to the lower bottom plate 403 by multiple second nuts 406 at one end, which utilizes the threaded connection between the second nuts 406 and the lower bottom plate 403. When the second nuts 406 are tightened, the axial pressure generated tightly presses the positioning plate 5 against the lower bottom plate 403, achieving stable connection between the two, preventing the positioning plate 5 from shifting or loosening during construction.

[0039] The positioning surface 501 at the corner of the positioning plate 5 abuts against the upper surface of the H-beam 1 based on the principle of plane contact. During the construction of the H-beam 1, the upper surface of the H-beam 1 serves as a reference plane, and the positioning surface 501 closely fits against it, limiting the vertical displacement and rotation of the positioning plate 5, thereby ensuring the horizontal state of the upper surface of the positioning plate 5. Since the stand 3 is connected to the positioning plate 5, it indirectly positions the vertical state of the stand 3.

[0040] The fixing function of the second nuts 406 ensures the stability of the positioning plate 5 during the entire construction process, allowing the positioning plate 5 to continuously and effectively perform its positioning function on the stand 3, improving the reliability of the measurement device.

[0041] The positioning surface 501 effectively ensures the horizontality of the positioning plate 5 and the verticality of the upright 3, reduces measurement errors caused by the tilt of the positioning plate 5 or the non-verticality of the upright 3, improves the installation accuracy of the grid beam 1, and helps to improve the overall quality of the shallow water area slide grid beam installation project.

[0042] In the preferred embodiment, the upright 3 is equipped with a scale, and multiple bubble level meters 302 are also mounted on the upper end of the upright 3. The scale on the upright 3 is based on the fundamental principle of length measurement; using the upright 3 as a reference, the scale markings visually reflect the relative positional change of the grid beam 1 along the direction of the upright 3. The bubble level meters 302 utilize the property of liquids remaining horizontal under gravity; when the upright 3 is vertical, the bubble will be located at the center of the instrument. Multiple bubble level meters 302 detect the verticality of the upright 3 from different directions, ensuring measurement accuracy.

[0043] The ruler provides construction workers with a convenient measurement tool, enabling them to quickly read the relative position data of the grid beam 1 and the uprights 3. This facilitates timely adjustment of the grid beam 1's position during installation, improving construction efficiency. The bubble meter 302 can visually display the verticality of the uprights 3, allowing construction workers to check and correct it at any time, ensuring the verticality of the measurement benchmark. This, in turn, improves the installation accuracy of the grid beam 1 and reduces installation errors caused by verticality deviations.

[0044] Example 2

[0045] Further explanation in conjunction with Example 1, such as Figures 1-7 As shown in the structure, S1, the track 2 of the grid beam 1 to be installed is mounted on the base 4, and the inner side of the positioning plate 5 on one side of the base 4 abuts against the end face of the vertical rod 3 at a distance for positioning.

[0046] S2. Use a square to measure that the upright 3 is perpendicular to the bottom plate 403 of the base 4. Then adjust the position of the upright 3 according to the positioning plate 5. After the position is adjusted, the first nut 405 under the base 4 abuts against the track 2, so that the entire base 4 is fixed on the track 2.

[0047] S3, uprights 3 and bases 4 are installed on the tracks 2 on both sides of the grid beam 1, and are positioned by positioning plates 5;

[0048] S4. Use a drone to scan and model the area of ​​the construction grid beam 1 to obtain a 3D construction drawing of the construction area. Combine the data of the installation of the grid beam 1 measured by the total station with the 3D construction drawing to form drawings of the installation positions of each grid beam 1. Later, the lifting point positions of the grid beam 1 will be located according to the drawings of the installation positions.

[0049] S5, the lifting device needs to lift the I-beam 1 to the pre-installation position, the GPS locator 6 displays the position of the I-beam 1, and the lifting device adjusts according to the now displayed position of the I-beam 1 to move the I-beam 1 to the position to be installed;

[0050] S6, after the I-beam 1 moves to the position to be installed, the I-beam 1 starts to be lowered and contacts the support pier, the two total stations 8 at the track axis align the axes at the top of the track, the hoisting equipment slightly lifts the two lifting points at the upper part of the I-beam, and after the top of the I-beam 1 reaches the designed position, the upper lifting point is lowered;

[0051] S6, the two total stations 8 at the track axis align the prisms 7 at the top of the vertical rod 3 at the lower part of the I-beam 1, and after measuring that the lower part of the I-beam 1 reaches the preset position, the lower part of the I-beam 1 starts to be slowly lowered, and the I-beam 1 is abutted on the support pier;

[0052] S7, after the I-beam 1 is abutted on the support pier, the construction personnel observe the water bubble instrument 302 on the vertical rod 3 to display whether the vertical rod 3 is in a vertical state, and finally adjust the lower part of the I-beam 1 according to the setting-out data of the structure water bubble instrument 302 and the total station 8, and after the lower part of the I-beam 1 is adjusted to the preset position, the lifting device is coordinated;

[0053] S8, according to the two GPS locators 6 on the I-beam 1, the installation position of the I-beam 1 is displayed, and compared with the 3D point position in step S4, if the data remains to be reported within 2 cm, it means that the I-beam 1 reaches the preset position.

[0054] Embodiment 3

[0055] Further illustrated in combination with Embodiment 1, as shown in the structure, the specific method of step S4 is: Figures 1-7

[0056] Firstly, a high-precision three-dimensional laser scanner is used to scan the whole construction I-beam 1 area by using a drone; the scanner collects data on the set flight path at a certain angular velocity and linear velocity, and obtains a large amount of point cloud data in the construction area, which contains the spatial information of the terrain, the existing foundation structure and the surrounding environment;

[0057] The collected point cloud data is transmitted to professional modeling software, and through processing based on feature extraction and spatial geometry algorithm, a 3D construction drawing of the construction area is constructed; in the modeling process, the software will automatically identify and fit different geometric shapes such as planes and curved surfaces according to the density and distribution of the point cloud data, and construct the corresponding topological structure;

[0058] ​Meanwhile, the key control points of the installation of the cross beam 1 are measured by using the total station 8; the total station obtains the three-dimensional coordinate data of these control points in the total station coordinate system by measuring the horizontal angle, the vertical angle and the distance; it is assumed that the total station coordinate system is , and the measured control point coordinates are , wherein , is the number of control points;

[0059] Then the data measured by the total station is registered and fused with the 3D construction drawing in the same coordinate system; this step needs to be realized by a coordinate conversion algorithm; it is assumed that the coordinate system of the 3D construction drawing is , and we need to find a conversion matrix , so that the control point coordinates measured by the total station can be converted to the coordinate system of the 3D construction drawing; the conversion matrix usually contains translation, rotation and scaling transformation parameters, which can be solved by optimization algorithms such as least squares method;

[0060] Finally, according to the fused data, combined with the design size and installation requirements of the cross beam 1, the installation position coordinates of each cross beam 1 are calculated, and detailed installation position drawings are drawn, including the plane position, elevation and relative relationship information of the cross beam 1 with the surrounding structure;

[0061] Coordinate conversion formula: let the point be the coordinate in the total station coordinate system, the coordinate in the 3D construction drawing coordinate system be , and the conversion matrix be :

[0062] ;

[0063] Then we have

[0064] ;

[0065] wherein is the element of the conversion matrix, and by measuring the coordinates of multiple common points in the two coordinate systems, an equation group can be established to solve these elements; the use of this formula is to realize the unified coordinate representation of the total station measurement data and the 3D construction drawing data, so as to carry out data fusion and analysis subsequently;

[0066] Cross beam installation position calculation: according to the design interval of the cross beam 1, the offset relative to a certain reference point , and the determined installation area boundary coordinates and ​, calculate the installation position coordinates of the H-beam (1) As follows:

[0067] ;

[0068] ;

[0069] ;

[0070] wherein j, k are the serial numbers of the H-beam in the and directions; the use of this formula is to accurately determine the installation position of each H-beam according to the design requirements and the on-site measurement data;

[0071] The specific method of step S5 is:

[0072] After the lifting device is started, the H-beam 1 is slowly lifted to a certain height; at this time, the GPS locator 6 on the H-beam 1 starts to receive satellite signals in real time and calculates its own position coordinates; the GPS locator 6 uses a positioning algorithm based on a satellite navigation system, measures the distance between the satellite and the locator, combines the orbit parameters and clock information of the satellite, and solves the longitude, latitude and elevation information of the locator in the WGS-84 coordinate system, and then converts it to the local coordinate system of the construction area through coordinate conversion;

[0073] At the same time, the controller equipped on the lifting device continuously reads the position data sent by the GPS locator 6 and compares it with the preset installation position coordinates of the H-beam 1 calculated in step S4;

[0074] The position coordinates of the H-beam 1 measured by the GPS locator 6 are , and the preset installation position coordinates are ;

[0075] According to the difference between the two, the offset of the H-beam 1 in the horizontal direction and the vertical direction is calculated , , ;

[0076] According to the calculated offset, the lifting device adjusts the angle, telescopic length or lifting height of the lifting arm through its own hydraulic or electric drive system, so that the H-beam 1 gradually approaches the preset installation position; during the adjustment process, the position data of the GPS locator 6 is continuously monitored, and the offset is updated in real time, until the position of the H-beam 1 meets the preset accuracy requirement, and it is moved to the installation position;

[0077] The specific method of step S8 is:

[0078] After the installation of the H-beam 1, the position coordinate data of the two GPS locators 6 on the H-beam 1 are read again, and are recorded as and respectively.

[0079] According to the coordinate data of the two GPS locators 6, the actual installation position center coordinate of the H-beam 1 is calculated as , and the calculation formula is as follows:

[0080] ;

[0081] ;

[0082] ;

[0083] The actual installation position center coordinate calculated is compared with the preset position coordinate of the H-beam 1 in the 3D point map generated in step S4, and the deviation amount of the two in each direction is calculated as , , ;

[0084] It is judged whether the deviation amount is within 2cm, and if the requirement is met, it indicates that the installation position of the H-beam 1 is accurate; if it exceeds the allowable range, the reason needs to be analyzed, and re-measurement and adjustment may be needed.

[0085] The above embodiment is only a preferred technical solution of the present application, and should not be regarded as a limitation of the present application. The protection scope of the present application should be the technical solution recorded in the claims, including the equivalent replacement scheme of the technical features recorded in the claims. That is, the equivalent replacement improvement within this range is also within the protection scope of the present application.
