Description

Technical Field

[0001] This invention belongs to the field of steel structure factory construction technology, specifically to a smart auxiliary fixing and tilt monitoring device for steel structure columns and its control method. Background Technology

[0002] Steel structure factory buildings are widely used in industrial construction due to their advantages such as high strength, short construction period, and good environmental performance. During construction, steel beams, columns, and other components require temporary or permanent fixation using fixing devices to ensure construction accuracy and structural stability. Existing equipment often uses only a single clamping method to fix factory columns. This method only achieves preliminary positioning and cannot monitor the column's tilt in real time during the fixing process. Current methods for measuring column tilt often require manual measurement, but factory columns are generally tall, affecting the accuracy of manual measurements and preventing real-time feedback and adjustments. Furthermore, traditional construction separates fixing and inspection processes; if the clamp fails inspection after clamping, it needs to be loosened and adjusted, resulting in low efficiency. Manual measurement relies on experience, and high-altitude operations pose significant risks. It is impossible to record the trajectory of column tilt changes, making it difficult to trace construction quality. By the time problems are discovered, accumulated errors have often occurred, increasing rework costs. This application integrates clamping and detection components, and introduces tilt sensors, displacement sensors, angle sensors and control units to achieve real-time monitoring of tilt, automatic calibration and closed-loop control while fixing the column. This solves the problems of separation of fixing and detection, low accuracy of manual measurement, and inability to adjust and trace in real time in the prior art. Summary of the Invention

[0003] This invention provides an intelligent auxiliary fixing and tilt monitoring device for steel structure columns and its control method. The first technical problem it aims to solve is to achieve simultaneous column fixing and tilt monitoring, addressing the inefficiency caused by the separation of fixing and testing processes in traditional construction. The second technical problem it aims to solve is to improve the accuracy of tilt detection, avoiding misjudgments from single-point contact, and addressing the low accuracy of manual measurements. The third technical problem it aims to solve is to eliminate the influence of installation errors and uneven ground on the test results, addressing the problem of distorted test data. The fourth technical problem it aims to solve is to achieve data recording and traceability during the construction process, addressing the problem of lack of evidence for later acceptance. The fifth technical problem it aims to solve is to automatically adjust the clamping state based on the test results, addressing the problems of delayed adjustment and excessive manual intervention.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A smart auxiliary fixing and tilt monitoring device for steel structure columns, comprising steel structure factory columns, characterized in that it further includes: A supporting base plate, the top of which is provided with a U-shaped groove for the vertical passage of the steel structure factory column; A clamping assembly, which is mounted on a support base plate and is used to support the columns of the steel structure factory building; The detection assembly includes a side-mounted base fixed to the outer wall of the rear side of the support base plate. The side-mounted base has a hollow interior. An electric telescopic device is fixedly connected to the center of the interior of the side-mounted base. A detection support is fixedly connected to the output end of the telescopic rod. Two detection bases are installed inside the detection support. The two detection bases form a rectangular space for the steel structure factory column to pass through. Several pressure detection bases are fixed at equal intervals on opposite sides of the rectangular space. Each pressure detection base is equipped with a pressure sensor. A contact block is installed at the end of each pressure detection base that is away from the detection base and extends into the rectangular space. The contact block is electrically connected to the pressure sensor. Several warning lights are fixed at equal intervals on the top of the two detection bases. Each warning light corresponds to and is electrically connected to one of the pressure detection bases.

[0005] More preferably, it also includes a tilt sensor mounted on the support base plate to detect the tilt state of the device itself; a control unit electrically connected to the telescopic rod, clamping assembly, pressure sensor, warning light, and tilt sensor respectively; a displacement sensor is also provided in the pressure detection base to detect the amount of compression displacement of the contact block; an angle sensor is provided between the detection base and the detection support to detect the rotation angle of the detection base; the tilt sensor, displacement sensor, and angle sensor all have built-in alarms.

[0006] Furthermore, the electric telescopic device includes an internal partition that conforms to the internal space of the side fixed base. A cylinder is fixedly connected to the bottom of the internal partition, and a base plate is fixedly connected to the output end of the cylinder. A telescopic rod is provided on the top surface of the internal partition.

[0007] Furthermore, the interior of the detection support base is hollow, and two rotating shafts are symmetrically fixedly connected inside the detection support base. The left ends of the two detection bases are symmetrically provided with through holes. The two rotating shafts correspond one-to-one with the two through holes. The rotating shafts pass through the through holes, allowing the detection bases to rotate around the rotating shafts. The detection bases are U-shaped in overall shape, and the through holes are opened in the vertical part of the U-shaped structure.

[0008] Furthermore, a second fixing plate is fixedly connected to the end of each of the two detection bases away from the detection support. Two bolt holes are symmetrically opened on the surface of the two second fixing plates. Bolts are threadedly connected to the inner wall of the bolt holes. A bolt sleeve is fixedly connected to the outer wall of the second fixing plate on the right side. The bolts are threadedly connected to the inner wall of the bolt sleeve.

[0009] Furthermore, the clamping assembly includes four first fixing plates fixed at the four corners of the rectangular space where the supporting base plate is located. The two first fixing plates located on the rear side are rotatably connected to a bidirectional lead screw facing each other. The outer wall of the bidirectional lead screw is symmetrically threaded with two threaded blocks. The front outer wall of each of the two threaded blocks is fixedly connected with a connecting rod. The two first fixing plates located on the front side are each connected in series with a sliding rod. The ends of the two sliding rods that are close to each other are fixedly connected with a fixing block. The two sliding rods that are far away from each other are fixedly connected with a limiting block. The fixing block and its corresponding threaded block are connected through a connecting rod. A motor is fixedly connected to the outer wall of the first fixing plate on the left side of the rear side. The output end of the motor is fixedly connected to the bidirectional lead screw. A clamping plate support column is fixedly connected at the center of the top of each of the two connecting rods. The two clamping plate support columns are symmetrically fixedly connected to two U-shaped clamping plates facing each other. The two U-shaped clamping plates are adapted to the steel structure factory column.

[0010] A control method for an intelligent auxiliary fixing and tilt monitoring device for steel structure columns, using the fixing device described in any one of claims 1-6, characterized by comprising the following steps: Step S1: Initialization and Self-Test After the control unit is powered on, it first checks whether each sensor is communicating normally and reads the initial data. If any sensor malfunctions, an alarm will sound to indicate a fault.

[0011] Step S2: Device positioning and fixing The operator pushes the device next to the column to be fixed, allowing the U-shaped groove to engage with the bottom of the column and locking the casters. The control unit activates the cylinder, pushing the base plate down to press against the ground, enhancing the device's stability.

[0012] Step S3: Clamping component action The control unit drives the motor to rotate forward, which in turn rotates the bidirectional lead screw, causing the two U-shaped clamping plates to synchronously approach the column until the clamping force reaches the set threshold. The motor encoder records the clamping stroke position as a reference.

[0013] Step S4: Calibrate the detection components Install the calibration block on the testing base. Control the telescopic rod to move the testing base to a predetermined height until the contact block contacts the vertical surface of the calibration block, and the contact pressure reaches a preset value. At this time, the control unit records the readings of all pressure sensors as zero-point pressure F0, the readings of all displacement sensors as zero-point displacement D0, and the readings of all angle sensors as zero-point angle A0. After calibration, remove the calibration block.

[0014] Step S5: Multi-point tilt monitoring The control unit sequentially moves the detection base to multiple heights of the column (such as the bottom, middle, and top), bringing the contact block into contact with the column surface at each height to collect pressure, displacement, and angle data. The actual tilt direction and tilt amount of the column are calculated through multi-point fitting.

[0015] Step S6: Data Analysis and Closed-Loop Control If the tilt at a certain height exceeds the first preset threshold (e.g., 2mm), the control unit drives the clamping component to make fine adjustments and apply a corrective torque; if it exceeds the second preset threshold (e.g., 5mm), an audible and visual alarm is triggered and automatic adjustment is paused, prompting manual intervention.

[0016] Step S7: Data Recording and Traceability The control unit records all sensor data and timestamps at a set frequency (e.g., 1Hz), generates a column tilt change curve, and uploads it to local storage or a cloud platform for easy quality traceability later.

[0017] Step S8: Construction completed and repositioned After construction is completed, the control unit releases the clamping component, retracts the detection component, unlocks the casters, and the device can move to the next construction position.

[0018] Compared with the prior art, the present invention has the following features and beneficial effects: This application integrates the clamping component and the detection component into the same device and sets up a control unit for unified coordination, thereby enabling real-time monitoring of the tilt status while fixing the column, solving the problems of separation of fixing and detection and cumbersome procedures in traditional construction.

[0019] This application, by adding a displacement sensor inside the pressure detection base and using an angle sensor to collect data at multiple points, can accurately calculate the tilt direction and tilt amount of the column, avoiding misjudgment due to single-point contact and solving the problem of low accuracy in manual measurement.

[0020] This application achieves zero-point calibration of the detection components and self-check of the device's horizontal state by setting up a calibration block and tilt sensor, eliminating the influence of installation errors and uneven ground on the detection results and solving the problem of distorted detection data.

[0021] This application achieves traceability of construction quality by recording sensor data in real time through the control unit and generating a column tilt change curve, thus solving the problem of having no basis for acceptance in the later stage.

[0022] This application achieves intelligent construction by automatically fine-tuning the clamping components based on tilt monitoring results through closed-loop control, reducing manual intervention and solving the problems of adjustment lag and low efficiency. Attached Figure Description

[0025] To make the technical means, innovative features, objectives and effects of this invention easier to understand, the invention will be further described below.

[0026] The embodiments described herein are specific implementations of the present invention, used to illustrate the concept of the invention, and are illustrative and exemplary, and should not be construed as limiting the implementation or scope of the invention. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0027] Example 1: Device Structure This embodiment provides an intelligent auxiliary fixing and tilt monitoring device for steel structure columns, such as... Figures 1-6 As shown, the specific structure is as follows: The movable base includes a support base plate 2, the top of which has a U-shaped groove 14 for engaging with the bottom of the steel structure factory column 1. Casters 3 are equidistantly fixed at the four corners of the bottom of the support base plate 2 for easy movement and positioning. The casters 3 are equipped with a braking mechanism that can lock after positioning.

[0028] The clamping assembly is mounted on the top of the support base plate 2, including four first fixing plates 9 symmetrically fixed at the four corners of the support base plate 2. A bidirectional lead screw 10 is rotatably connected between the two first fixing plates 9 located on the rear side. Two threaded blocks 11 are symmetrically threaded to the outer wall of the bidirectional lead screw 10, and a connecting rod 18 is fixedly connected to the front outer wall of each of the two threaded blocks 11. A slide rod 16 is slidably passed through each of the two first fixing plates 9 located on the front side. A fixing block 17 is fixedly connected to the end of the two slide rods 16 that is close to each other, and a limit block 15 is fixedly connected to the end of the two slide rods 16 that is away from the fixing block 17. The ends of the two connecting rods 18 that are away from the threaded blocks 11 are fixedly connected to the corresponding fixing blocks 17. A motor 8 is fixedly mounted on the outer wall of the first fixing plate 9 on the left front side, and the output end of the motor 8 is fixedly connected to the bidirectional lead screw 10. A clamping support column 13 is fixedly connected to the center of the top of each of the two connecting rods 18. Two U-shaped clamping plates 12 are symmetrically fixed to the two clamping support columns 13 facing each other. Rubber pads are provided on the inner side of the U-shaped clamping plates 12 to avoid damaging the surface of the column. The U-shaped clamping plates 12 are adapted to the shape of the steel structure factory column 1 and fit tightly when clamped.

[0029] The detection assembly is installed on the rear side of the support base plate 2, including a side-fixed base 4 fixed to the outer wall of the rear side of the support base plate 2. The side-fixed base 4 has a hollow interior, with an internal partition 23 fixedly connected in the center. An electric telescopic device is fixedly installed on the top of the internal partition 23. In this embodiment, an electric push rod is used as the telescopic rod 5, and the output end of the telescopic rod 5 is fixedly connected to a detection support 6. The detection support 6 has a hollow interior, with two symmetrically fixed rotating shafts 19 inside. Each of the two detection bases 7 has a through hole 20 at its left end, and the two rotating shafts 19 pass through the corresponding through holes 20, allowing the detection base 7 to rotate around the rotating shafts 19. The detection base 7 is U-shaped overall, with the through holes 20 located in the vertical part of the U-shaped structure. The two detection bases 7 form a rectangular space to accommodate the column 1. Inside the rectangular space, on opposite sides, several pressure detection bases 30 are fixed at equal intervals along the length direction. Each pressure detection base 30 contains a pressure sensor and a displacement sensor 32. A contact block 29 is installed at the end of the pressure detection base 30 away from the detection base 7. The contact block 29 is elastically connected to the pressure detection base 30 by a spring (not shown), and the displacement of the contact block 29 is detected by the displacement sensor 32. Several warning lights 28 are fixed at equal intervals on the top of the two detection bases 7. Each warning light 28 is electrically connected to a pressure sensor inside one of the pressure detection bases 30.

[0030] An angle sensor 31 is also provided between the detection base 7 and the detection support 6 to detect the rotation angle of the detection base 7 around the rotation axis 19. The calibration block is an L-shaped precision-machined part made of high-strength metal, with its two mutually perpendicular precision-machined surfaces corresponding to the reference surface of the detection base 7 and the theoretical vertical surface of the column 1, respectively. The calibration block is connected to the detection support 6 via a quick-release structure, which can be magnetic, slotted, or screw-fixed for rapid installation and removal. The calibration block is used for zero-position calibration of the detection components, eliminating the influence of installation errors and sensor drift on the detection results.

[0031] A cylinder 21 is fixedly connected to the bottom of the internal partition 23, and a base plate 22 is fixedly connected to the output end of the cylinder 21. When the device is positioned, the cylinder 21 pushes the base plate 22 downward to contact the ground, increasing overall stability.

[0032] Control and Sensing Unit An inclination sensor 35 is installed on the support base plate 2 to detect the horizontal state of the device itself. The control unit 36, which uses a PLC controller or an embedded industrial computer, is electrically connected to the motor 8, the telescopic rod 5, the pressure sensor, displacement sensor 32, angle sensor 31, inclination sensor 35 of the pressure sensing device, the warning light 28, and the alarm 37. The alarm 37 is an audible and visual alarm used to sound an alarm in case of abnormality.

[0033] Sensor installation location and working method The tilt sensor 35 is fixedly mounted at the center of the upper surface of the support base plate 2, near the rear side of the U-shaped groove 14, ensuring that it can accurately sense the overall level of the device and provide a reference for subsequent calibration and monitoring. During operation, the control unit 36 ​​reads the data from the tilt sensor 35 in real time for device self-testing and ground adaptation adjustments.

[0034] Displacement sensors 32 are built into each pressure detection base 30, with their sensing ends connected to the tail end of contact blocks 29. Contact blocks 29 are elastically connected to the pressure detection base 30 via springs. When contact blocks 29 contact the column 1 and are compressed, displacement sensors 32 accurately measure the displacement of the contact blocks 29, thus reflecting the unevenness of the column surface relative to the reference surface of the detection base. Displacement sensors 32 employ high-precision linear displacement sensors with a resolution of 0.01 mm.

[0035] Angle sensor 31 is installed at the connection between the detection base 7 and the detection support 6, specifically on one side of the rotating shaft 19. The sensor body is fixed to the inner wall of the detection support 6, and its rotation axis is coaxially connected to the rotation center of the detection base 7. When the detection base 7 rotates around the rotating shaft 19, the angle sensor 31 outputs the rotation angle value in real time to determine the angular position of the detection base 7 relative to the detection support 6. The angle sensor 31 uses a high-precision angle encoder with a resolution of 0.01°.

[0036] In terms of operation, the three sensors work together: first, the tilt sensor 35 ensures the device is level; during the calibration phase, the angle sensor 31 and displacement sensor 32 record the zero-point reference; during the tilt monitoring phase, the control unit 36 ​​controls the rotation of the detection base 7 based on the reading of the angle sensor 31, causing the contact block 29 to contact the column with constant pressure. Simultaneously, the displacement sensor 32 measures the compression of each contact block. Combined with the angle value from the angle sensor 31, a multi-point fitting algorithm calculates the tilt direction and amount of the column. This multi-sensor fusion method effectively eliminates single-point measurement errors and improves the accuracy and reliability of tilt monitoring.

[0037] Example 2: Control Method This embodiment provides a control method using the device described in Embodiment 1, such as... Figure 6 As shown, it includes the following steps: Step S1: Initialization and Self-Test After the control unit 36 ​​is powered on, it first checks whether each sensor (tilt sensor 35, displacement sensor 32, angle sensor 31, etc.) is communicating normally and reads the initial data. If any sensor is abnormal, a fault prompt is issued through the alarm 37.

[0038] Step S2: Device positioning and fixing The operator pushes the device next to the column 1 to be fixed, so that the U-shaped groove 14 engages with the bottom of the column, locking the casters 3. The control unit 36 ​​activates the cylinder 21, pushing the base plate 22 down to press it into the ground, enhancing the stability of the device.

[0039] Step S3: Clamping component action The control unit 36 ​​drives the motor 8 to rotate forward, which in turn drives the bidirectional lead screw 10 to rotate, causing the two U-shaped clamping plates 12 to synchronously approach the column 1 until the clamping force reaches the set threshold. The motor encoder records the clamping stroke position as a reference.

[0040] Step S4: Calibrate the detection components The calibration block is installed on the testing base. The telescopic rod is controlled to move the testing base to a predetermined height, until the contact block contacts the vertical surface of the calibration block, and the contact pressure reaches a preset value. At this point, the control unit records the readings of all pressure sensors as zero-point pressure F0, the readings of all displacement sensors as zero-point displacement D0, and the readings of all angle sensors as zero-point angle A0. After calibration, the calibration block is removed. The purpose of the calibration block is to provide a reference surface independent of the column; therefore, the contact block should contact the calibration block, not the column, during calibration. This design ensures that subsequent measurements of the column accurately reflect its tilt state, unaffected by installation errors of the device itself.

[0041] Step S5: Multi-point tilt monitoring The control unit 36 ​​sequentially moves the detection base 7 to multiple heights of the column (such as the bottom, middle, and top), causing the contact block 29 to contact the column surface at each height to collect pressure, displacement, and angle data. The actual tilt direction and tilt amount of the column are calculated through multi-point fitting.

[0042] Step S6: Data Analysis and Closed-Loop Control If the tilt at a certain height exceeds the first preset threshold (e.g., 2mm), the control unit 36 ​​drives the clamping component to make fine adjustments and applies a corrective torque; if it exceeds the second preset threshold (e.g., 5mm), an audible and visual alarm is triggered and automatic adjustment is paused, prompting manual intervention.

[0043] Step S7: Data Recording and Traceability The control unit 36 ​​records all sensor data and timestamps at a set frequency (e.g., 1Hz), generates a column tilt change curve, and uploads it to local storage or a cloud platform for easy quality traceability later.

[0044] Step S8: Construction completed and repositioned After construction is completed, the control unit 36 ​​drives the clamping component to release, retracts the detection component, unlocks the caster wheel 3, and the device can move to the next construction position.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
