Description

Technical Field

[0001] This invention relates to the field of damper positioning equipment technology, and more specifically, to a precise positioning system and method for vibration dampers in building engineering. Background Technology

[0002] In building energy dissipation and vibration reduction projects, the installation and positioning accuracy of dampers directly determines the structural vibration reduction performance and long-term safety. Traditional construction methods have significant drawbacks: 1. The positioning of embedded parts relies on manual stringing and welding, which makes X / Y / Z three-way adjustment inconvenient and prone to misalignment, tilting, and elevation deviation, resulting in the inability to install the damper or eccentric force.

[0003] 2. The embedded parts are rigidly connected to the reinforcing bars and formwork, which makes them prone to displacement and tilting during concrete pouring and vibration. Furthermore, there is no means of monitoring the entire process, so deviations cannot be detected and corrected in real time.

[0004] 3. The handling and docking of dampers rely on manual lifting, which results in low alignment accuracy and efficiency, and is prone to collision damage to embedded parts and the damper body.

[0005] 4. The positioning, leveling, handling, and monitoring devices are independent of each other and do not form an integrated closed-loop control system, resulting in large cumulative errors, cumbersome procedures, and uncontrollable quality.

[0006] Existing technologies only address problems in a single aspect and cannot achieve precise positioning, intelligent monitoring, automatic correction, and efficient integration of the entire process. This makes it difficult to meet the high-precision, intelligent, and traceable construction requirements of modern building seismic isolation engineering. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a precise positioning system and method for vibration dampers in building engineering, a three-way independent precision adjustment system with high-precision control capability, which can flexibly adapt to a variety of dampers of different specifications, and its positioning accuracy reaches ±0.5 mm, ensuring the accuracy of the installation process.

[0008] A precise positioning system for vibration dampers in building engineering includes a horizontal positioning plate. A lifting assembly is fixedly installed on the horizontal positioning plate. The lifting assembly is connected to a formwork support frame. The four lower corners of the horizontal positioning plate are respectively connected to a sandwich positioning module through a three-way adjustment module. The sandwich positioning module is connected to a positioning plate adjustment module. The three-way adjustment module includes a guide sleeve, which is fixed to the lower four corners of the horizontal positioning plate. A threaded post is screwed into the guide sleeve, and the threaded post is connected to the guide sleeve via a guide assembly. The lower end of the threaded post is fixedly connected to the ball of a universal ball joint via a connecting post. The ball groove of the universal ball joint is formed on the lower positioning plate. An upper positioning plate is positioned on the upper side of the lower positioning plate. A locking block is fixedly set at each of the four lower corners of the upper positioning plate, and the locking block matches a locking groove. The locking groove is formed on the lower positioning plate. A positioning block groove is also formed on one side of the locking groove on the lower positioning plate. A positioning protrusion is fixedly set on one side of the locking block, and the positioning protrusion matches the positioning block groove. A straight groove and a round hole are formed on the upper positioning plate, and the straight groove communicates with the round hole. The connecting post passes through the straight groove.

[0009] Furthermore, the guide assembly includes a guide rod, one end of which is fixedly connected to a slider. The slider is slidably disposed within an annular channel, which is formed on the upper arc surface of the threaded column. The guide rod is slidably engaged with a groove, which is formed on the guide sleeve.

[0010] Furthermore, the sandwich positioning module includes an annular disk with a set of circumferentially evenly arranged oblique grooves. Each oblique groove contains a bolt, which is screwed to a nut. The lower end of the bolt is fixed to one end of a connecting rod. The connecting rod is rotatably connected to a fixed shaft, which is fixed to the positioning plate adjustment module. The other end of the connecting rod is located in the central hole of the annular disk, and a positioning post is fixedly installed on the upper side of the other end of the connecting rod.

[0011] Furthermore, a handle is fixedly connected to the upper side of the annular disc.

[0012] Furthermore, the positioning plate adjustment module includes a positioning plate, which is annular. The four sides of the lower positioning plate are respectively provided with strip-shaped holes. An adjustment screw is provided in the strip-shaped holes. The adjustment screw is screwed to the positioning plate. The outer end of the adjustment screw is fixedly connected to the screw head. The screw head is spherical and is inserted into a groove formed by symmetrically arranged C-rings. The C-rings are fixed to one end of the adjustment knob. A groove ring is provided on the arc-shaped surface of the adjustment knob.

[0013] Furthermore, it also includes a positioning module, which includes a linear module. The slide rails of the linear module are fixed to the four sides of the upper positioning plate. The lower end of the sliding block of the linear module is slidably connected to a stop block. The stop block matches the groove ring. The stop block is screwed with an adjusting bolt. The adjusting bolt is rotatably connected to the sliding block.

[0014] Furthermore, the lifting assembly is an electric push rod.

[0015] Furthermore, it also includes a dual-axis tilt sensor, mounted on the positioning plate, to monitor the levelness and tilt angle in real time with an accuracy of ±0.05°; Laser displacement sensors are installed on both sides of the formwork support to monitor the X / Y / Z coordinates of the embedded parts in real time with an accuracy of ±0.5mm.

[0016] A method for using a precise positioning system for vibration dampers in building engineering includes the following steps: S1: Establishing an installation benchmark: S1.1 Use a total station to mark out the damper installation axis, the center of the embedded parts and the design elevation, clarify the installation reference points and complete the establishment of the work reference; S1.2 After the entire device is assembled, use anchor bolts to fix the formwork support 1 to the floor slab or beam surface, level the formwork support, and lock it after leveling to ensure the stability of the formwork support. S1.3 Place the horizontal positioning plate smoothly at the reference position in the work area; S1.4 Combines real-time monitoring data from a universal electronic level and a dual-axis tilt sensor, and uses the vertical and horizontal angle fine-tuning functions of the three-way adjustment module to calibrate the levelness of the horizontal positioning plate, ensuring that the levelness deviation meets the engineering design requirements, and uses it as the benchmark for positioning embedded parts. S2: Casting and temporary fixing of embedded parts: S2.1 Use existing temporary fixing components to temporarily fix the embedded parts to ensure that the embedded parts do not shift during the pouring process; S2.2 Concrete pouring operation is carried out on the fixed embedded parts, and the concrete is poured evenly and densely during the pouring process; S2.3 Once the concrete to be poured has completely solidified and the concrete has reached the required solidification standard, remove and take away the temporary fixing components of the embedded parts. S3: Damper handling and initial alignment: S3.1 The multi-functional damper handling and docking device is used to smoothly transport the damper to the designated work area, avoiding damage or displacement of the damper during the transportation process; S3.2 Adjust the height of the damper using the device's lifting assembly and unfold the folding guide plate for auxiliary guidance to ensure accurate movement of the damper; S3.3, in conjunction with the real-time monitoring data of the laser displacement sensor, adjusts the position of the damper to achieve initial alignment between the mounting end of the damper and the embedded part, and controls the alignment deviation to a minimum. S4: Damper sandwich clamping and centering calibration: S4.1 Rotate the handle on the annular disk to rotate the annular disk, causing the bolt to slide in the inclined groove, thereby driving the connecting rod to rotate around the fixed axis; During the rotation of S4.2 connecting rod, the positioning column moves radially synchronously until the positioning column is tightly fitted with the outer wall of the damper, thus achieving a sandwich-type clamping of the damper; S4.3 simultaneously monitors the center position of the damper through a laser displacement sensor and fine-tunes the clamping position to ensure that the center of the damper is precisely aligned with the center of the embedded part; After S4.4 clamping is completed, a comprehensive check of the clamping stability of the damper is performed to confirm that the positioning pin is not loose, the damper is not offset, and there is no shaking. S4.5 uses a universal electronic level and a dual-axis tilt sensor to monitor the levelness and tilt angle of the damper and records all monitoring data in detail. S5. Damper can be precisely adjusted in multiple dimensions: S5.1 Height Adjustment: The telescopic rod of the lifting assembly is extended and retracted through the central control terminal, which drives the formwork support 1 and the damper to rise and fall synchronously; By combining the Z-axis coordinate data of the damper monitored by the laser displacement sensor with the preset design height, the extension and retraction of the lifting component is finely adjusted to ensure that the damper height accurately meets the design requirements. S5.2 Horizontal position adjustment: If the laser displacement sensor detects a deviation in the X / Y coordinates of the damper, adjust the adjustment knob of the positioning plate adjustment module and rotate the adjustment screw. The adjusting screw rotates to move the positioning plate and the sandwich-type positioning module, fine-tuning the X / Y position of the damper until the coordinate deviation meets the design requirements; After adjustment, the linear module of the positioning module drives the abutment to move, and the adjusting bolt is rotated to make the abutment engage in the groove ring of the adjusting knob, thus fixing the adjusting knob and preventing it from shifting, ensuring that the adjustment position is locked. S5.3 Tilt Angle Adjustment: If the dual-axis tilt sensor detects that the tilt angle of the damper exceeds the allowable range, remove the upper and lower positioning plates; By rotating the omnidirectional ball, the angle of the lower positioning plate is finely adjusted, thereby adjusting the tilt angle of the damper until the tilt angle meets the design requirements. After the angle adjustment is completed, the upper and lower positioning plates are re-engaged. The angle of the upper and lower positioning plates is locked by the cooperation of the locking block and the locking groove, and the positioning protrusion and the positioning block groove, to ensure that the levelness and tilt angle of the damper meet the standards. S6: Parameter Verification and Final Fixation: After the positioning and adjustment are completed, the monitoring data of each sensor, including the coordinates, levelness, and tilt angle of the damper, are integrated through the central control terminal. The integrated monitoring data is then compared with the preset standard parameters to confirm that all parameters meet the engineering design requirements and are without deviation. After confirming that the damper is accurately positioned, the alignment and connection of the damper and the embedded parts are completed. Furthermore, in step S6, if there is a slight deviation, the adjustment steps in step five are repeated until all parameters meet the design requirements.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are: The three-way independent precision adjustment system has high-precision control capabilities and can flexibly adapt to various dampers of different specifications. Its positioning accuracy reaches ±0.5 mm, ensuring the accuracy of the installation process. Through multi-sensor fusion monitoring technology, dynamic monitoring of the entire process, from the setting of embedded parts to concrete pouring and precise connection of components, is realized, making the construction process completely controllable. The use of a sandwich bottom mold combined with an adjustable support structure effectively eliminates the limitations of steel bar layout, fundamentally preventing displacement during the pouring process and ensuring the forming quality of the components. Designed for reusability, this not only effectively reduces material costs per construction project but also simplifies on-site procedures, thereby ensuring a significant increase in the first-time construction pass rate. All key monitoring data are automatically collected and stored, fully recording detailed information for each stage of construction, ensuring the traceability of the entire construction process, and providing reliable data support for quality management and subsequent analysis.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings: Combination Figures 1 to 7 A precise positioning system for vibration dampers in building engineering includes a horizontal positioning plate 3, on which a lifting assembly is fixedly installed. The lifting assembly is connected to a formwork support frame 1. The four lower corners of the horizontal positioning plate 3 are respectively connected to a sandwich positioning module 6 through a three-way adjustment module 4. The sandwich positioning module 6 is connected to a positioning plate adjustment module 7. Formwork support 1 is a galvanized steel formwork support frame; The lifting assembly uses electricity to drive the telescopic rod to extend and retract, which in turn drives the formwork support frame 1 to rise and fall synchronously, thereby adjusting the overall height of the system. The formwork support frame 1 is used to assist in fixing the damper and works with the lifting assembly to achieve precise control of the damper's height. The horizontal positioning plate 3 ensures that the installation reference of each adjustment module and sensor is level, avoiding the impact of reference deviation on positioning accuracy. The lifting assembly replaces manual adjustment, realizing the automation and precision of height adjustment and reducing human operation errors. The formwork support frame 1 provides temporary fixation and support for the damper and works with the lifting assembly to complete the damper's height positioning.

[0021] The three-way adjustment module 4 includes a guide sleeve 401, which is fixed to the lower four corners of the horizontal positioning plate 3. A threaded post 402 is screwed into the guide sleeve 401, and the threaded post 402 is connected to the guide sleeve 401 via a guide assembly. The lower end of the threaded post 402 is fixedly connected to the ball of a universal ball 408 via a connecting post 407. The ball groove of the universal ball 408 is formed on the lower positioning plate 406. An upper positioning plate 403 is disposed on the upper side of the lower positioning plate 406, and a locking block is fixedly disposed at each of the four lower corners of the upper positioning plate 403. 409, the locking block 409 matches the locking slot 4010, the locking slot 4010 is formed on the lower positioning plate 406, and the lower positioning plate 406 also has a positioning block groove 40101 located on one side inside the locking slot 4010. A positioning protrusion 4091 is fixedly provided on one side of the locking block 409, and the positioning protrusion 4091 matches the positioning block groove 40101. The upper positioning plate 403 has a straight groove 4032 and a round hole 4031. The straight groove 4032 communicates with the round hole 4031, and the connecting post 407 passes through the straight groove 4032. The connecting post 407 can move within the straight groove 4032 to avoid interference caused by the movement of the positioning protrusion 4091.

[0022] The three-way adjustment module 4 achieves vertical height fine-tuning through the screw connection between the guide sleeve 401 and the threaded post 402; it achieves horizontal angle fine-tuning through the rotational engagement of the ball joint 408 and the ball groove; and it achieves horizontal position positioning and fixing through the engagement of the upper positioning plate 403 and the lower positioning plate 406's locking block 409, locking groove 4010, positioning protrusion 4091, and positioning block groove 40101. Combined with the guide components, it ensures the stability and accuracy of the adjustment process, solves the problems of vertical height deviation and horizontal angle offset during damper installation, and enables fine-tuning of the damper in the X, Y, and Z directions. This ensures the horizontality and positional accuracy of the damper installation, while the positioning structure prevents displacement after adjustment, ensuring positioning stability. The ball of the omnidirectional ball 408 rotates and engages with the ball groove of the lower positioning plate 406, enabling angle adjustment to meet the fine-tuning needs of different angles in the horizontal direction. The locking block 409 of the upper positioning plate 403 matches the locking groove 4010 of the lower positioning plate 406, and the positioning protrusion 4091 matches the positioning block groove 40101. The upper and lower positioning plates are fixed through the locking structure, preventing loosening after the upper and lower positioning plates are fixed. The locking positioning structure ensures that the adjusted angle and position are fixed, preventing angle deviation due to vibration during construction and ensuring positioning accuracy.

[0023] The guiding assembly includes a guide rod 405, one end of which is fixedly connected to a slider 4051. The slider 4051 is slidably disposed in an annular channel 4021, which is formed on the upper arc surface of the threaded post 402. The guide rod 405 is slidably engaged with a groove 404, which is formed on the guide sleeve 401.

[0024] One end of the guide rod 405 is fixed to the slider 4051, which is slidably disposed in the annular channel 4021 of the threaded column 402. The guide rod 405 simultaneously slides and engages with the groove 404 on the guide sleeve 401 to form a bidirectional guiding constraint, which restricts the rotation trajectory of the threaded column 402 in the guide sleeve 401 and only allows it to rise and fall along the axial direction of the guide sleeve 401. This avoids deviation and shaking during the rising and falling of the threaded column 402, ensures the stability and accuracy of the rising and falling adjustment of the threaded column 402, prevents the threaded column 402 from tilting and causing vertical adjustment deviation, and thus avoids the damper positioning deviation.

[0025] The guide sleeve 401 can be set with a scale to facilitate observation of the distance the guide rod 405 moves.

[0026] The sandwich-type positioning module 6 includes an annular disk 601, on which a set of circumferentially evenly arranged inclined sliding grooves 603 are provided. Each inclined sliding groove 603 is provided with a bolt 604, which is screwed to a nut 602. The lower end of the bolt 604 is fixed to one end of the upper side of the connecting rod 607. The connecting rod 607 is rotatably connected to a fixed shaft 608, which is fixed to the positioning plate adjustment module 7. The other end of the connecting rod 607 is located in the central hole of the annular disk 601, and a positioning post 605 is fixedly provided on the upper side of the other end of the connecting rod 607.

[0027] A handle 606 is fixedly connected to the upper side of the annular disc 601. The handle 606 is designed for easy manual operation, thereby improving construction efficiency.

[0028] The inclined grooves 603 on the annular disk 601 are evenly arranged around the circumference. When the bolt 604 slides in the inclined groove 603, it will drive the connecting rod 607 to rotate around the fixed shaft 608. Since the inclination angle of the inclined groove 603 is fixed, the sliding of the bolt 604 will be converted into the radial movement of the other end of the connecting rod 607, which will drive the positioning pin 605 to move radially in sync. Through the synchronous movement of multiple positioning pins 605, the damper is clamped and positioned in a sandwich manner. The handle 606 on the annular disk 601 makes it easy to manually rotate the annular disk 601 to adjust the position of the bolt 503 in the inclined groove 603, so as to realize the appropriate clamping of dampers of different sizes. Through the evenly distributed positioning pins 605, it is ensured that the damper is subjected to uniform force when it is clamped, avoiding damage to the damper during the clamping process. At the same time, the center position of the damper is accurately positioned to ensure the coaxiality of the damper installation, providing a basis for subsequent positioning and adjustment.

[0029] The positioning plate adjustment module 7 includes a positioning plate 701, which is annular. The lower positioning plate 406 has four center slots 703 on its four sides. An adjustment screw 702 is installed in each slot 703. The adjustment screw 702 is screwed to the positioning plate 701. The outer end of the adjustment screw 702 is fixedly connected to a screw head 7021, which is spherical. The screw head 7021 is inserted into a groove formed by symmetrically arranged C-rings 7041. The C-rings 7041 are fixed to one end of an adjustment knob 704. A grooved ring 7042 is provided on the arc-shaped surface of the adjustment knob 704.

[0030] The positioning plate 701 has a ring structure, which is suitable for the installation of the sandwich-type positioning module 6. The strip hole 703 of the lower positioning plate 406 provides movement space for the adjusting screw 702. The adjusting screw 702 is screwed to the positioning plate 701. When the adjusting knob 704 is rotated, the spherical screw head 7021 rotates in the groove formed by the C ring 7041, which drives the adjusting screw 702 to move along the strip hole 703, thereby adjusting the position of the positioning plate 701. The grooved ring 7042 of the adjusting knob 704 is used to cooperate with the abutment 5011 of the positioning module 5 to achieve the fixation after adjustment, ensuring that the positioning position of the damper matches the engineering design position and making up for the small deviations in the previous adjustment. The grooved ring 7042 of the adjusting knob 704 cooperates with the abutment 5011 to fix the adjusted position and prevent the positioning plate 701 from shifting due to vibration during construction, thus ensuring the stability of the positioning accuracy. The cooperation between the spherical screw head 7021 and the C ring 7041 reduces the rotation resistance.

[0031] It also includes a positioning module 5, which includes a linear module 502. The slide rail of the linear module 502 is fixed to the four sides of the upper positioning plate 403. The lower end of the sliding block of the linear module 502 is slidably connected to the abutment block 5011. The abutment block 5011 matches the groove ring 7042. The abutment block 5011 is screwed to the adjusting bolt 503. The adjusting bolt 503 is rotatably connected to the sliding block.

[0032] The slide rail of the linear module 502 is fixed on all four sides of the upper positioning plate 403. The sliding block can move horizontally along the slide rail, driving the abutment block 5011 to move synchronously. The abutment block 5011 matches the groove ring 7042 of the adjusting knob 704. The height and position of the abutment block 5011 are adjusted by adjusting the adjusting bolt 503, so that the abutment block 5011 is inserted into the groove ring 7042, thereby fixing the adjusting knob 704. The adjusting bolt 503 is screwed to the abutment block 5011 and rotatably connected to the sliding block. Rotating the adjusting bolt 503 can finely adjust the abutment block 5011. The position of block 5011 ensures precise fit between block 5011 and groove ring 7042; the adjustment knob 704 of the fixed positioning plate adjustment module 7 prevents the knob from loosening after adjustment, thus preventing positioning deviation and further ensuring the stability of damper positioning; the linear module 502 can adjust the horizontal position of block 5011 to match the adjustment knob 704 in different positions; the adjustment bolt 503 can finely adjust the height and position of block 5011 to ensure a tight fit between block 5011 and groove ring 7042 and improve the fixing effect.

[0033] The lifting assembly is an electric push rod 2.

[0034] It also includes a dual-axis tilt sensor, which is installed on the positioning plate 701 to monitor the levelness and tilt angle in real time with an accuracy of ±0.05°. Through the built-in sensitive element, the levelness and tilt angle of the positioning plate 701 are detected in real time with a measurement accuracy of ±0.05°. The detected angle data is transmitted to the central control terminal in real time to monitor the levelness and tilt status of the damper installation, detect angle deviations in a timely manner, provide data support for subsequent correction, and avoid the damper's shock absorption effect being affected by the levelness or tilt angle exceeding the standard.

[0035] Laser displacement sensors are installed on both sides of the formwork support 1 to monitor the X / Y / Z coordinates of the embedded parts in real time with an accuracy of ±0.5mm. Through laser emission and reception, the X, Y, and Z coordinates of the embedded parts are detected in real time, and the coordinate data is transmitted to the central control terminal in real time for comparison with the design coordinates.

[0036] The universal electronic level features a digital display of the horizontal status and real-time data upload. Utilizing digital display technology, it monitors the system's horizontal status in real time and uploads the data to the central control terminal. This allows staff to intuitively view the horizontal condition, offering high measurement accuracy and convenient reading. The universal electronic level is installed at the four upper corners of the horizontal positioning plate 3, covering a 360-degree horizontal range. High-precision sensors convert the horizontal status into digital signals, which, combined with the real-time data display interface of the central control terminal, enable visual monitoring of the horizontal status. When the system's horizontal deviation exceeds a set threshold, an alarm is triggered for timely adjustment.

[0037] It also includes a central control terminal, which is electrically connected to the universal electronic level and each sensor. This central control terminal integrates display, alarm, storage, and analysis functions to form a closed loop of monitoring, early warning, and correction. It receives real-time data transmitted from each sensor and compares it with preset standard data. When the data exceeds a threshold, it automatically issues an alarm signal. Simultaneously, it stores the data, analyzes the causes of deviations, and provides a basis for correction operations, forming a closed-loop control system. This achieves intelligent control and precise monitoring of the system, replacing manual real-time monitoring, improving monitoring efficiency and accuracy, promptly detecting positioning deviations and safety hazards, facilitating rapid correction measures by staff, ensuring the quality of damper installation, and allowing the stored construction data to be used for subsequent project review and quality traceability.

[0038] It also includes a multi-functional damper handling and docking device (existing product), which is equipped with a lifting plate, a folding guide plate and a winch traction mechanism. It works with a laser displacement sensor to automatically align the damper with the embedded parts, and uses a total station to mark the damper installation axis, the center position of the embedded parts and the design elevation, thus establishing a unified benchmark for the entire installation operation.

[0039] The working process of this invention is as follows: Using a total station, the damper installation axis, the center of the embedded parts, and the design elevation are laid out to establish the installation benchmark. After assembling the device, the formwork support 1 is fixed to the floor slab or beam surface with anchor bolts, leveled, and locked. The installation of the steel frame, positioning steel plate, and three-way adjustment mechanism is completed. The horizontal positioning plate 3 is placed stably in the benchmark position of the work area. The horizontal state of the horizontal positioning plate 3 is adjusted. Combined with the monitoring data of the universal electronic level and the dual-axis tilt sensor, the horizontality of the horizontal positioning plate 3 is calibrated through the vertical direction and horizontal angle fine adjustment function of the three-way adjustment module 4 to ensure that its deviation is within the allowable range (meeting the engineering design requirements), which serves as the benchmark for the positioning of the embedded parts.

[0040] After fixing the embedded parts with existing temporary fixing components, the embedded parts are poured. After the concrete is poured, wait for it to solidify. After solidification, remove the temporary fixing components and use the multi-functional damper handling and docking device to smoothly transport the damper to the work area. Adjust the height of the damper through the lifting component of the device, use the folding guide plate to assist in guidance, and cooperate with the real-time monitoring of the laser displacement sensor to make the installation end of the damper initially aligned with the embedded parts, and control the alignment deviation within the minimum range.

[0041] Rotating the handle 606 on the annular disk 601 causes the disk to rotate, allowing the bolt 604 to slide within the inclined groove 603. This, in turn, causes the connecting rod 607 to rotate around the fixed shaft 608, and the positioning post 605 moves radially synchronously until it fits against the outer wall of the damper, achieving a sandwich-type clamping of the damper. During clamping, a pressure sensor monitors the clamping force to ensure uniform force distribution and prevent excessive clamping force from damaging the damper. Simultaneously, a laser displacement sensor monitors the center position of the damper to ensure alignment between the damper center and the embedded part center. After clamping, the clamping stability of the damper is checked again to ensure that the positioning post 605 is not loose and that the damper does not shift or wobble. A universal electronic level and a dual-axis tilt sensor monitor the levelness and tilt angle of the damper, and the monitoring data is recorded. The telescopic rod of the lifting assembly can be extended and retracted via the central control terminal, driving the formwork support 1 and the damper to rise and fall synchronously. Combined with the damper's Z-axis coordinate data monitored by the laser displacement sensor, and compared with the preset design height, the extension and retraction of the lifting assembly is finely adjusted to ensure the damper's height accurately meets design requirements. Simultaneously, the support force balance of the formwork support 1 is monitored by a pressure sensor. If the force is uneven, the extension and retraction of the lifting assembly is adjusted to ensure balanced force. If the laser displacement sensor detects a deviation in the X / Y coordinates of the damper, the adjustment knob 704 of the positioning plate adjustment module 7 is used to rotate the adjustment screw 702, moving the positioning plate 701 and the sandwich-type positioning module 6 to finely adjust the damper's X / Y position until the coordinate deviation meets design requirements. After adjustment, the linear module 502 of the positioning module 5 moves the abutment block 5011, and the adjustment bolt 503 is rotated to engage the abutment block 5011 within the groove ring 7042 of the adjustment knob 704, fixing the adjustment knob 704 and preventing displacement. If the dual-axis tilt sensor detects that the damper's tilt angle exceeds the allowable range, disassemble the upper and lower positioning plates. Using the rotation of the universal ball 408, fine-tune the angle of the lower positioning plate 406 to adjust the damper's tilt angle. After adjustment, re-engage the upper and lower positioning plates 406. Fix the angle by engaging the locking block 409 with the locking groove 4010 and the positioning protrusion 4091 with the positioning block groove 40101, ensuring the damper's levelness and tilt angle meet design requirements. After positioning and adjustment, integrate the monitoring data (coordinates, levelness, tilt angle) from each sensor through the central control terminal and compare them comprehensively with the preset standard parameters to confirm that all parameters meet the engineering design requirements without deviation. If there are minor deviations, repeat the above adjustment steps until the requirements are met. After confirming the damper's accurate positioning, complete the alignment and connection between the damper and the embedded parts, further reinforcing each connection point to ensure a secure connection.

[0042] Collect the final damper installation accuracy data, integrate the monitoring data throughout the entire process, generate a complete installation monitoring report, complete the project acceptance, and archive all construction data to achieve traceability of the entire construction process.

[0043] This invention also discloses a method for using a precise positioning system for seismic dampers in building engineering, comprising the following steps: A method for using a precise positioning system for vibration dampers in building engineering includes the following steps: S1: Establishing an installation benchmark: S1.1 Use a total station to mark out the damper installation axis, the center of the embedded parts and the design elevation, clarify the installation reference points and complete the establishment of the work reference; S1.2 After the entire device is assembled, use anchor bolts to fix the formwork support 1 to the floor slab or beam surface, level the formwork support, and lock it after leveling to ensure the stability of the formwork support. S1.3 Place the horizontal positioning plate 3 smoothly at the reference position in the work area; S1.4 Combines the real-time monitoring data of the universal electronic level and the dual-axis tilt sensor, and through the vertical and horizontal angle fine-tuning functions of the three-way adjustment module 4, calibrates the levelness of the horizontal positioning plate 3 to ensure that the levelness deviation meets the engineering design requirements, and uses it as the benchmark for the positioning of the embedded parts. S2: Casting and temporary fixing of embedded parts: S2.1 Use existing temporary fixing components to temporarily fix the embedded parts to ensure that the embedded parts do not shift during the pouring process; S2.2 Concrete pouring operation is carried out on the fixed embedded parts, and the concrete is poured evenly and densely during the pouring process; S2.3 Once the concrete to be poured has completely solidified and the concrete has reached the required solidification standard, remove and take away the temporary fixing components of the embedded parts. S3: Damper handling and initial alignment: S3.1 The multi-functional damper handling and docking device is used to smoothly transport the damper to the designated work area, avoiding damage or displacement of the damper during the transportation process; S3.2 Adjust the height of the damper using the device's lifting assembly and unfold the folding guide plate for auxiliary guidance to ensure accurate movement of the damper; S3.3, in conjunction with the real-time monitoring data of the laser displacement sensor, adjusts the position of the damper to achieve initial alignment between the mounting end of the damper and the embedded part, and controls the alignment deviation to a minimum. S4: Damper sandwich clamping and centering calibration: S4.1 Rotate the handle 606 on the annular disk 601 to drive the annular disk 601 to rotate, so that the bolt 604 slides in the inclined groove 603, thereby driving the connecting rod 607 to rotate around the fixed shaft 608. During the rotation of S4.2 connecting rod 607, it drives the positioning post 605 to move radially in sync until the positioning post 605 is tightly fitted with the outer wall of the damper, thereby achieving a sandwich-type clamping of the damper. S4.3 uses a laser displacement sensor to monitor the center position of the damper and fine-tune the clamping position to ensure that the center of the damper is precisely aligned with the center of the embedded part. After clamping S4.4, thoroughly check the clamping stability of the damper to confirm that the positioning post 605 is not loose, the damper is not offset, and there is no shaking. S4.5 uses a universal electronic level and a dual-axis tilt sensor to monitor the levelness and tilt angle of the damper and records all monitoring data in detail. S5. Damper can be precisely adjusted in multiple dimensions: S5.1 Height Adjustment: The telescopic rod of the lifting assembly is extended and retracted through the central control terminal, which drives the formwork support 1 and the damper to rise and fall synchronously; By combining the Z-axis coordinate data of the damper monitored by the laser displacement sensor with the preset design height, the extension and retraction of the lifting component is finely adjusted to ensure that the damper height accurately meets the design requirements. During the adjustment process, the support force balance of the formwork support 1 is monitored by the pressure sensor. If uneven force occurs, the extension and retraction range of the lifting component is adjusted until the force on the formwork support is balanced. S5.2 Horizontal position adjustment: If the laser displacement sensor detects a deviation in the X / Y coordinates of the damper, adjust the adjustment knob 704 of the positioning plate adjustment module 7 and rotate the adjustment screw 702. The adjusting screw 702 rotates, causing the positioning plate 701 and the sandwich-type positioning module 6 to move, fine-tuning the X / Y position of the damper until the coordinate deviation meets the design requirements; After adjustment, the linear module 502 of the positioning module 5 drives the abutment 5011 to move, and the adjusting bolt 503 is rotated to make the abutment 5011 engage in the groove ring 7042 of the adjusting knob 704, thereby fixing the adjusting knob 704, preventing it from shifting, and ensuring that the adjustment position is locked. S5.3 Tilt Angle Adjustment: If the dual-axis tilt sensor detects that the tilt angle of the damper exceeds the allowable range, remove the upper and lower positioning plates; By rotating the universal ball 408, the angle of the lower positioning plate 406 is finely adjusted, thereby adjusting the tilt angle of the damper until the tilt angle meets the design requirements. After the angle adjustment is completed, the upper and lower positioning plates 406 are re-engaged. The angle of the upper and lower positioning plates is locked by the cooperation of the locking block 409 and the locking groove 4010, and the positioning protrusion 4091 and the positioning block groove 40101, to ensure that the levelness and tilt angle of the damper meet the standards. S6: Parameter Verification and Final Fixation: After the positioning and adjustment are completed, the monitoring data of each sensor, including the coordinates, levelness, and tilt angle of the damper, are integrated through the central control terminal. The integrated monitoring data is then compared with the preset standard parameters to confirm that all parameters meet the engineering design requirements and are without deviation. After confirming that the damper is accurately positioned, the alignment and connection of the damper and the embedded parts are completed. In step S6, if there is a slight deviation, the adjustment steps in step five are repeated until all parameters meet the design requirements.
