Description

Technical Field

[0001] The present invention relates to the technical field of force detection, and in particular to a device and method for detecting the force of front and rear supports of a diamond-shaped hanging basket. Background Art

[0002] In bridge engineering, diamond-shaped gantry cranes are key equipment for cantilever construction. Monitoring the stress conditions of their front and rear supports plays a crucial role in ensuring construction safety and structural stability. Traditional support force monitoring methods primarily involve installing pressure sensors on the supports, connecting them to the diamond-shaped gantry crane, and using contact testing to obtain support force data.

[0003] However, this traditional detection method has exposed numerous problems in practical applications. Because pressure sensors sense the forces acting on the supports through direct contact, they are subject to forces from multiple directions under the complex working conditions of construction sites. During the installation and movement of the hanging basket and the pouring of concrete, horizontal friction, impact forces, and torsional forces caused by structural deformation are unavoidable. These multi-directional forces exceed the design tolerance of the pressure sensor. Long-term exposure can cause irreversible damage to the sensitive components and mechanical structure within the sensor, severely impacting its service life and reliability. This, in turn, requires frequent sensor repair and replacement, increasing construction costs and time, and reducing efficiency.

[0004] On the other hand, the interference of multi-directional forces makes it difficult for pressure sensors to accurately measure the true vertical force magnitude of the support. Because these additional forces will be superimposed and coupled with the vertical force, the signal output by the sensor becomes complex and unstable, and it is impossible to accurately separate and extract the vertical force information, resulting in large errors and uncertainties in the detection results. This inaccurate detection data cannot truly reflect the stress state of the support, causing great trouble for construction personnel when evaluating the safety and stability of the hanging basket structure. It is difficult to make accurate judgments and decisions, which in turn increases the safety risks during the construction process and may lead to serious engineering accidents such as hanging basket collapse and excessive structural deformation, posing a serious threat to personnel safety and project quality.

[0005] To sum up, the traditional method of installing pressure sensors on the supports and using contact detection can no longer meet the requirements of accurate force monitoring and long-term stable and reliable operation of the front and rear supports of the diamond hanging basket in modern bridge construction. There is an urgent need for a new support force detection equipment and method that can effectively solve the above problems to ensure the smooth progress of bridge construction and improve the quality of the project.

[0041] The present invention provides a technical solution: a force detection device for front and rear supports of a diamond-shaped hanging basket, which mainly comprises a diamond-shaped frame and a detection system.

[0042] The diamond-shaped frame consists of a first connecting block 101, a second connecting block 102, a third connecting block 103, and a fourth connecting block 104, all of which are hollow. The side walls between the first connecting block 101 and the second connecting block 102 are fixedly connected to a lower horizontal steel bar 105 by welding or other means. The side walls where the lower horizontal steel bar 105 connects to the first and second connecting blocks 101, 102 are each provided with a through-hole, and the two through-holes are located in the two ends of the lower horizontal steel bar 105. The side walls between the third connecting block 103 and the fourth connecting block 104 are fixedly connected to an upper horizontal steel bar 106. The side walls where the upper horizontal steel bar 106 connects to the third and fourth connecting blocks 103, 104 are also provided with a through-hole, and the two through-holes are located in the two ends of the upper horizontal steel bar 106. A first oblique steel bar 107 is fixedly connected between the first connecting block 101 and the third connecting block 103. The two ends of the first oblique steel bar 107 are fixedly mounted on the inclined surfaces opened by the first connecting block 101 and the third connecting block 103, and the inclined surfaces located between the two ends of the first oblique steel bar 107 are respectively provided with through holes. A second oblique steel bar 108 is fixedly connected between the second connecting block 102 and the fourth connecting block 104. The two ends of the second oblique steel bar 108 are fixedly mounted on the inclined surfaces opened by the second connecting block 102 and the fourth connecting block 104, and the inclined surfaces located between the two ends of the second oblique steel bar 108 are respectively provided with through holes. In addition, an intermediate supporting square steel bar 109 is fixedly connected between the second connecting block 102 and the third connecting block 103. The upper end of the intermediate supporting square steel bar 109 is tilted toward the direction of the first connecting block 101, and its centerline passes perpendicularly through the axis of the second turntable 202 and the third turntable 203, playing an auxiliary support and force distribution role in the entire structure.

[0043] During actual installation, the bottom of the first connecting block 101 is fixedly connected to the rear support via bolts and other fasteners, ensuring a tight fit and accurate transmission of forces acting on the rear support. The bottom of the second connecting block 102 is similarly securely connected to the front support, ensuring that forces acting on the front support are effectively transmitted to the frame. The top surface of the fourth connecting block 104 is fixedly connected to the front upper crossbeam of the diamond-shaped hanging basket.

[0044] The detection system includes a first turntable 201, a second turntable 202, a third turntable 203, and a fourth turntable 204, which are rotatably mounted inside the first connecting block 101, the second connecting block 102, the third connecting block 103, and the fourth connecting block 104, respectively. To achieve the rotation of the turntables, a first motor, a second motor, a third motor, and a fourth motor are fixedly mounted on the side walls of the first connecting block 101, the second connecting block 102, the third connecting block 103, and the fourth connecting block 104, respectively. The output ends of the first motor, the second motor, the third motor, and the fourth motor are axially connected to the centers of the end faces of the first turntable 201, the second turntable 202, the third turntable 203, and the fourth turntable 204, respectively. Driven by the motors, the angles of the turntables can be flexibly adjusted to meet the requirements of different measurement positions and angles.

[0045] A first laser ranging sensor 205 is fixedly mounted on the sidewall of the first turntable 201. During measurement, the laser beam of the first laser ranging sensor 205 coincides with the centerlines of the lower horizontal steel bar 105 and the first diagonal steel bar 107, respectively, ensuring measurement accuracy and reliability. A second laser ranging sensor 206 is fixedly mounted on the sidewall of the fourth turntable 204. During measurement, the laser beam of the second laser ranging sensor 206 coincides with the centerlines of the upper horizontal steel bar 106 and the second diagonal steel bar 108, respectively, enabling accurate measurement of the deformation of the relevant steel bars and, therefore, inferring the stress conditions. A first Bragg grating 207 and a first ranging plate 208 are fixedly mounted on the sidewall of the second turntable 202. The first Bragg grating 207 is aligned with the end of the lower horizontal steel bar 105, while the first ranging plate 208 is aligned with the end of the second diagonal steel bar 108, enabling data collection and analysis in coordination with the first laser ranging sensor 205. A second Bragg grating 209 and a second ranging plate 210 are fixedly mounted on the side wall of the third turntable 203. When the second Bragg grating 209 is aligned with the end of the first oblique steel 107, the second ranging plate 210 is aligned with the end of the upper horizontal steel 106, and cooperates with other components to complete the force detection of each key part.

[0046] Two light interference fringe collection assemblies 211 are mounted on the first turntable 201 and the fourth turntable 204, respectively. Each light interference fringe collection assembly 211 includes two electric push rods 2111 fixedly mounted on the turntable. The telescopic ends of the push rods 2111 are fixedly connected to a rectangular plate 2112, on which a beam splitter 2113, a plane mirror 2114, and an array photodetector 2115 are fixedly mounted. The position of the light interference fringe collection assembly 211 can be adjusted by extending and retracting the push rods 2111.

[0047] The detection system also includes a controller, which is connected to the array photoelectric detector 2115 and is used to collect interference fringe data and process and analyze the data throughout the detection process. The controller is also connected to various components such as the motors and laser ranging sensors to achieve automated control and data collection management for the entire detection system.

[0048] A method for detecting the force of front and rear supports of a diamond-shaped hanging basket comprises the following steps:

[0049] Step 1: After the diamond-shaped hanging basket is installed, align the first laser ranging sensor 205 and the first ranging plate 208 with the two ends of the lower horizontal steel 105 respectively, and measure the distance from the first laser ranging sensor 205 to the first ranging plate 208 as L1;

[0050] Similarly, the distance from the first laser ranging sensor 205 to the second ranging plate 210 is measured as L2, the distance from the second laser ranging sensor 206 to the second ranging plate 210 is measured as L3, and the distance from the second laser ranging sensor 206 to the first ranging plate 208 is measured as L4. These initial distance data will serve as the basic reference values ​​for subsequent force analysis and be used to compare the deformation of the square steel during construction.

[0051] Step 2: The first motor on the side of the first connecting block 101 drives the first turntable 201 to rotate, and the second motor on the side of the second connecting block 102 drives the second turntable 202 to rotate, respectively aligning the first laser ranging sensor 205 and the first Bragg grating 207 with the two end ports of the lower horizontal steel 105, and the electric push rod 2111 drives the rectangular plate 2112 to move, and moves the spectroscope 2113 to the position where the laser beam passes; the first laser ranging sensor 205 emits a laser beam, and a part of the laser beam passes through the spectroscope 2113 and reaches the first Bragg grating 207, and the first Bragg grating 207 moves along the original path. The light beam is reflected back to the beam splitter 2113 along the original path, and then the beam splitter reflects the first Bragg grating 207 toward the array photodetector 2115. When the laser beam emitted by the first laser ranging sensor 205 passes through the beam splitter 2113, another part of the light beam is reflected by the beam splitter 2113 to the plane mirror 2114. The plane mirror 2114 then reflects the light beam along the original path to the beam splitter 2113. The light beam passes through the beam splitter 2113 and interferes with the light reflected by the first Bragg grating 207. The interference data is monitored by the array photodetector 2115, and the array photodetector 2115 feeds the data back to the controller.

[0052] That is, the laser beam generates interference fringes under the synergistic effect of the light interference fringe collection component 211 and the first Bragg grating 207, and the controller collects the initial interference fringe data at the lower horizontal steel 105; similarly, the controller collects the initial interference fringe position data at the first oblique steel 107, the upper horizontal steel 106, and the second oblique steel 108;

[0053] Step 3: During the construction process, the fourth connecting block 104 is subjected to a vertical downward load force; the controller collects interference fringe position data during construction at the lower horizontal steel 105, the first oblique steel 107, the upper horizontal steel 106, and the second oblique steel 108;

[0054] In the lower horizontal steel 105, the interference fringe movement amount ΔI is the change in light intensity, and I1 is the coefficient related to the contrast of interference fringes;

[0055] The tensile force on the lower horizontal steel 105 is A is the cross-sectional area of ​​the square steel, E is the elastic modulus of the square steel material, and λ is the wavelength of the laser;

[0056] Similarly, the tension on the first oblique steel 107 N2 is the number of interference fringes moved in the first oblique steel 107;

[0057] Tensile force on upper horizontal steel 106 N3 is the number of interference fringes moving in the upper horizontal steel 106;

[0058] The tension on the second oblique steel 108 N4 is the number of interference fringes moved in the second rhombus steel 108;

[0059] Step 4: The rear support below the first connecting block 101 is subjected to a pulling force F1 from the lower horizontal steel 105 and a force F2 from the first oblique steel 107. The rear support is then subjected to a downward pulling force F in the vertical direction. 后支 , then F 后支 =F2sinα, α is the angle between the first oblique steel 107 and the lower horizontal steel 105;

[0060] The front support at the bottom of the second connecting block 102 is subjected to a thrust of F1 from the lower horizontal steel 105, a thrust of F5 from the middle supporting steel 109, and a pressure of F4 from the second oblique steel 108. The front support is subjected to a vertical downward pressure of F 前支 =cosγF5+cosβF4, γ is the angle of the middle supporting square steel 109 relative to the vertical direction, β is the angle of the second oblique square steel 108 relative to the vertical direction, where

[0061] Step 5: Step 3 to step 5, cycle; the controller controls F 后支 、F 前支 Make a judgment and send out an alarm signal when it is detected that the force data exceeds the preset safety threshold.

[0062] The detection system needs to be coordinated with the diamond structure layout to achieve accurate measurement through the above method, and the two complement each other.

[0063] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
