Description

Technical Field

[0001] This invention relates to the field of load detection technology for disc buckle supports, and in particular to a load sensing and detection device for disc buckle supports with ultra-large spans. Background Technology

[0002] In large-scale engineering projects such as construction and bridges, the modular nature of the disc-lock support structure makes the installation process simpler and more efficient. The connections and combinations between various components are clear and straightforward, which can significantly shorten the construction cycle. At the same time, its high load-bearing capacity can provide reliable support for large-scale projects, ensuring the stability and safety of the engineering structure. Furthermore, the ease of installation further enhances its practicality in engineering construction, reducing construction difficulty and labor costs. Therefore, the disc-lock support structure has been widely used due to its significant advantages.

[0003] However, when faced with special scenarios involving ultra-large spans, the load distribution and deformation monitoring of the support rods in the disc-lock support structure presents many challenging problems. Under current technological conditions, load detection mostly relies on static strain gauges or periodic manual measurements. While static strain gauges can acquire some strain data to a certain extent, due to the limitations of their working principle, they cannot reflect the dynamic deformation of the structure in real time during actual operation. Periodic manual measurement equipment uses traditional sensors that are mostly single-point contact measurements, which are greatly affected by environmental temperature, humidity, and electromagnetic interference, resulting in severe data drift and making it difficult to maintain long-term accuracy under complex working conditions. Secondly, traditional detection methods can usually only acquire static or quasi-static load data and cannot achieve dynamic real-time response.

[0004] Furthermore, existing testing devices have significant limitations in coverage, generally making it difficult to comprehensively and effectively test all positions of the disc-lock support rod. To improve testing accuracy and obtain more detailed and accurate information on support rod deformation, it is necessary to deploy a large number of traditional testing units for comprehensive testing. However, this approach would undoubtedly increase testing costs significantly, including equipment procurement costs, installation costs, and subsequent maintenance costs, placing a heavy burden on the project budget. Therefore, developing a new type of disc-lock support load testing device that can effectively solve the above problems is of vital importance for improving the safety and reliability of ultra-large span projects. Summary of the Invention

[0005] The purpose of this invention is to provide a load sensing and detection device for ultra-large span disc buckle supports, which improves the detection accuracy and adaptability of the device, and provides an efficient and reliable load sensing and monitoring solution for ultra-large span projects.

[0006] To achieve the above objectives, the present invention provides a load sensing and detection device for ultra-large span disc buckle supports, including a deformation detection mechanism and a tension application mechanism. The two sides of the disc buckle support rod are connected to the vertical support rod through disc buckle connectors. At least one tension application mechanism is arranged below the disc buckle support rod and is connected to the disc buckle support rod through a connecting clamp. The tension application mechanism is used to apply a downward tension to the disc buckle support rod. The deformation detection mechanism is arranged on the disc buckle support rod and is used to detect the deformation of the disc buckle support rod.

[0007] In this embodiment, the deformation detection mechanism includes a support tube, a guide tube, a detection tube, and a connecting strip. The detection tube is arranged parallel to the top of the disc buckle support rod, and the detection tube is fixed to the top of the disc buckle support rod by the connecting strip.

[0008] The guide tube is arranged parallel to the detection tube directly above it. The support tube and the guide tube are on the same horizontal plane and arranged parallel to each other. The inner cavities of the support tube and the guide tube are connected by a sealed connecting channel. A take-up roller coaxially arranged with the support tube is rotatably mounted inside the support tube. A first guide rod is coaxially arranged inside the guide tube. A second guide rod is coaxially arranged inside the detection tube. A detection line is wound on the take-up roller. One end of the detection line is fixed to the take-up roller, and the other end enters the guide tube through the connecting channel, passes around the upper side of the first guide rod, exits the guide tube and enters the detection tube, then passes around the lower side of the second guide rod inside the detection tube and re-enters the guide tube, where it is fixedly connected to the inner wall of the guide tube. A resistance meter for detecting the resistance of the detection line between the first guide rod and the second guide rod is installed on the guide tube.

[0009] In this embodiment, the contact surface between the connecting strip and the disc buckle support rod is an arc-shaped surface, and the inner diameter of the arc-shaped surface of the connecting strip matches the outer diameter of the disc buckle support rod.

[0010] In this embodiment, both ends of the support tube are supported on the ground by vertically arranged support frames. The support frame includes a telescopic support rod whose height is adjustable and whose height can be locked after telescopic extension. One end of the telescopic support rod is supported on the top surface by a base, and the other end is detachably connected to the support tube.

[0011] In this embodiment, a winding motor is mounted in the axial direction of the winding roller, and the winding motor is used to drive the winding roller to rotate.

[0012] In this embodiment, the tension application mechanism includes, from top to bottom, a connecting clamp, a connecting arm, a tensioning assembly, and a fixed base; the fixed base is fixed on the ground, the connecting arm is vertically arranged, the top of the connecting arm is fixed with a connecting clamp, one end of the tensioning assembly is installed on the fixed base, and the other end is connected to the connecting arm. The tensioning assembly is used to drive the connecting arm to move along its axial direction.

[0013] In this embodiment, the tensioning assembly includes a fixed platform, a driving assembly, and a driving amplification assembly. The driving amplification assembly is disposed between the connecting arm and the tensioning platform. The tensioning motor drives the driving amplification assembly to move through a driving rod, and the driving amplification assembly drives the connecting arm to move along its axial direction.

[0014] The drive assembly includes a tension motor and a drive rod. A connecting worm is mounted on the output shaft of the tension motor. The drive rod is vertically arranged and rotatably mounted on a fixed platform. A connecting worm wheel is coaxially fixed to the lower end of the drive rod. The connecting worm meshes with the connecting worm wheel. A connecting gear is coaxially fixed to the upper end of the drive rod. The diameter of the connecting worm wheel is larger than the diameter of the connecting gear.

[0015] The drive amplification component includes two wedge blocks arranged parallel to each other and mirror-staggered. The two wedge blocks are slidably connected to each other, and the bottom surface of the wedge blocks is an inclined surface to form a working surface. Racks are installed on the sides of the two wedge blocks and are arranged horizontally. Guide sliders are also installed on the wedge blocks. A groove is opened on the top of the fixed platform. The wedge blocks are slidably installed in the groove through the guide sliders. The connecting gear is placed within the groove range, and the connecting worm gear is meshed between the two racks.

[0016] A connecting frame is fixed to the lower part of the connecting arm. The connecting frame is positioned directly above the middle of the slide groove. The middle of the connecting frame is provided with a sliding area that matches two wedge blocks. The two wedge blocks are slidably inserted into the sliding area from both sides of the connecting frame. The working surface of the wedge blocks is slidably connected to the bottom of the connecting frame. In the working state, the wedge blocks move horizontally relative to each other. The two wedge blocks move horizontally relative to each other. The inclined working surface at the bottom of the wedge blocks is slidably connected to the connecting frame, thereby converting the horizontal movement of the wedge blocks into the vertical movement of the connecting frame.

[0017] In this embodiment, a pressure sensor is provided between the lower end of the connecting arm and the connection point of the connecting frame.

[0018] In this embodiment, an auxiliary roller is provided on the contact surface between the connecting frame and the working surface of the wedge block.

[0019] In this embodiment, the fixed platform is mounted on a fixed base via a vertically arranged screw drive mechanism. The fixed base includes a support base and a fixed base plate. The fixed base plate is fixed to the ground, and the support base is fixed to the fixed base plate via columns. Two drive motors are mounted on the support base, and drive screws are mounted on the output shafts of the drive motors. The two drive screws are threaded to both ends of the fixed platform.

[0020] Due to the above structure, the present invention has the following advantages:

[0021] 1. The deformation detection mechanism employs a detection line circuit design. Through the design of the detection line, guide rod, and resistance circuit, the resistance of the resistance circuit increases as the deformation of the disc buckle support rod increases, enabling real-time feedback of the support rod's deformation. This allows for precise detection of the disc buckle support rod's deformation by matching the changes in the detection line length with the resistance. Furthermore, the detection line is U-shaped, effectively doubling its length and improving detection accuracy. Simultaneously, a tension application mechanism, using a worm gear and wedge block amplification mechanism, converts horizontal motion into vertical tension through the wedge block. This effectively and slowly applies downward tension to the disc buckle support rod while simultaneously achieving high-tonnage tension with a small motor. The rack and pinion bidirectional synchronous drive ensures balanced force application.

[0022] 2. The deformation detection mechanism is tightly fitted to the disc buckle support rod through the connecting strip to ensure the stability of the detection tube. The detection line is set with a margin in the initial setting to match the rapid response deformation. The resistance detector monitors and transmits resistance data in real time, providing a basis for accurately obtaining the amount of deformation.

[0023] 3. The tension application mechanism is equipped with a pressure sensor at the lower end of the connecting arm, which can monitor the tensile strength in real time while monitoring the deformation, so as to achieve precise control of the detection pressure;

[0024] 4. The installation process of this device is clear and straightforward, and the connection of each component is simple and stable. When using it, you can complete the test by following the steps. It can effectively obtain the deformation position and deformation amount of the disc buckle support rod under specific loads, providing strong data support for the safety assessment of ultra-large span disc buckle support structures.

[0025] In summary, this device, through its mechatronics design, solves the problems of low accuracy and poor adaptability of traditional detection devices, providing an efficient and reliable load sensing and monitoring solution for ultra-large span projects. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0041] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0042] like Figure 1 As shown, a load sensing and detection device for a large-span disc buckle support includes a deformation detection mechanism and a tension application mechanism. The two sides of the disc buckle support rod 1 are connected to the vertical support rod through disc buckle connectors. At least one tension application mechanism is arranged below the disc buckle support rod 1 and is connected to the disc buckle support rod 1 through a connecting clamp 24. The tension application mechanism is used to apply a downward tension to the disc buckle support rod 1. The deformation detection mechanism is arranged on the disc buckle support rod 1 and is used to detect the deformation of the disc buckle support rod 1.

[0043] like Figure 5 As shown, the deformation detection mechanism includes a support tube 2, a guide tube 3, a detection tube 4, and a connecting strip 5. The detection tube 4 is arranged parallel above the disc buckle support rod 1. The detection tube 4 is fixed to the top of the disc buckle support rod 1 by the connecting strip 5. There can be multiple connecting strips 5, which are evenly distributed along the length of the disc buckle support rod 1, or the connecting strip 5 can be matched with the length of the disc buckle support rod 1. The contact surface between the connecting strip 5 and the disc buckle support rod 1 is an arc-shaped surface. The inner diameter of the arc-shaped surface of the connecting strip 5 matches the outer diameter of the disc buckle support rod 1, so that the detection tube 4 is more tightly fixed to the disc buckle support rod 1.

[0044] The guide tube 3 is arranged parallel to the detection tube 4 directly above it. The support tube 2 and the guide tube 3 are on the same horizontal plane and arranged parallel to each other. The inner cavities of the support tube 2 and the guide tube 3 are connected by a sealed connecting channel 27. A take-up roller 6, coaxially arranged with the support tube 2, is rotatably mounted inside the support tube 2. A first guide rod 7 is coaxially arranged inside the guide tube 3. A second guide rod 8 is coaxially arranged inside the detection tube 4. A detection line 9 is wound on the take-up roller 6. One end of the detection line 9 is fixed to the take-up roller 6, and the other end is connected through the connecting channel. 27 enters the guide tube 3, passes around the upper side of the first guide rod 7, exits the guide tube 3 and enters the detection tube 4, then passes around the lower side of the second guide rod 8 inside the detection tube 4 and re-enters the guide tube 3 and is fixedly connected to the inner wall of the guide tube 3. A resistance detector is installed on the guide tube 3 to detect the resistance of the detection line 9 between the first guide rod 7 and the second guide rod 8. When the distance between the detection tube 4 and the guide tube 3 increases, the length of the detection loop formed by the detection line 9 between the first guide rod 7 and the second guide rod 8 increases, and the resistance of the detection loop increases.

[0045] like Figure 5As shown, the resistance detector includes two detection terminals 10. One detection terminal 10 is fixed inside the guide tube 3 and connected to one end of the detection line 9 fixed inside the guide tube 3. The other detection terminal 10 is also fixed inside the guide tube 3, and the detection line 9 slides through this detection terminal 10 to achieve the connection between the detection line 9 and this detection terminal 10. In this way, the detection line 9 forms a detection loop between the two detection terminals 10. The resistance detector detects the resistance of the detection loop and transmits the resistance data to the controller in a timely manner.

[0046] In the initial state, the detection line 9 in the connection channel is set to be relaxed, so that the detection line 9 has a certain margin. When the length of the detection loop increases, the detection line 9 can be released quickly.

[0047] like Figure 2 and Figure 5 As shown, further, both ends of the support tube 2 are supported on the ground by vertically arranged support frames 11. The support frame 11 includes a telescopic support rod whose height is adjustable and can be locked after telescopic extension. One end of the telescopic support rod is supported on the top surface by a base, and the other end is detachably connected to the support tube 2. A winding motor is installed in the axial direction of the winding roller 6. The winding motor is used to drive the winding roller 6 to rotate and to wind up the detection line 9 after the detection is completed.

[0048] like Figures 6 to 13 As shown, the tension application mechanism includes a connecting arm 12, a tensioning assembly, and a fixed base 14 from top to bottom. The fixed base 14 is fixed to the ground by anchor bolts, etc. The connecting arm 12 is vertically arranged, and a connecting clamp 24 is fixed to the top of the connecting arm 12. The connecting arm 12 is detachably connected to the disc buckle support rod 1 through the connecting clamp 24. The tensioning assembly is used to drive the connecting arm 12 to move along its axial direction.

[0049] The tensioning assembly includes a fixed platform 15, a drive assembly and a drive amplification assembly. The drive amplification assembly is disposed between the connecting arm 12 and the tensioning platform. The tensioning motor 13 drives the drive amplification assembly to move through the drive rod 16. The drive amplification assembly drives the connecting arm 12 to move along its axial direction, thereby driving the connecting clamp 24 to pull the disc buckle support rod 1 downward.

[0050] The drive assembly includes a tension motor 13 and a drive rod 16. A connecting worm gear 17 is mounted on the output shaft of the tension motor 13. The drive rod 16 is vertically arranged and rotatably mounted on a fixed platform 15. A connecting worm wheel 18 is coaxially fixed to the lower end of the drive rod 16. The connecting worm gear 17 meshes with the connecting worm wheel 18. A connecting gear 19 is coaxially fixed to the upper end of the drive rod 16. The diameter of the connecting worm wheel 18 is larger than the diameter of the connecting gear 19.

[0051] The drive amplification assembly includes two parallel and mirror-staggered wedge blocks 20, which are slidably connected to each other. The bottom surface of each wedge block 20 is inclined to form a working surface. Racks 21 are mounted on the sides of the two wedge blocks 20 and are arranged horizontally. Guide sliders are also mounted on the wedge blocks 20. A groove 23 is provided on the top of the fixed platform 15. The wedge blocks 20 are slidably installed in the groove 23 through the guide slider. A limiting mechanism is provided between the guide slider and the groove 23 to prevent the guide slider from disengaging from the groove 23. A connecting gear 19 is placed within the groove 23. A connecting worm gear 18 is meshed between the two racks 21.

[0052] A connecting frame 22 is fixed to the lower part of the connecting arm 12. The connecting frame 22 is positioned directly above the middle of the slide groove 23. The middle part of the connecting frame 22 is provided with a sliding area that matches the two wedge blocks 20. The two wedge blocks 20 are slidably inserted into the sliding area from both sides of the connecting frame 22. The working surface of the wedge block 20 is slidably connected to the bottom of the connecting frame 22. The connecting gear 19 of the drive component rotates, thereby driving the two wedge blocks 20 to move relative to each other. By utilizing the inclined working surface at the bottom of the wedge block 20, the horizontal movement of the wedge block 20 is converted into the vertical movement of the connecting frame 22. Thus, the connecting frame 22 is pulled down by the wedge block 20, and the connecting arm 12 applies a pulling force to the disc buckle support rod 1.

[0053] Furthermore, a pressure sensor is installed between the lower end of the connecting arm 12 and the connection point of the connecting frame 22 to detect the tensile strength of the tension application mechanism in real time, thereby controlling the detected pressure. An auxiliary roller is provided on the contact side between the connecting frame 22 and the working surface of the wedge block 20 to ensure smooth movement between the wedge block 20 and the connecting frame 22.

[0054] like Figure 11 As shown, the fixed platform 15 is mounted on the fixed base 14 via a vertically arranged screw drive mechanism. The fixed base 14 includes a support base and a fixed base plate. The fixed base plate is fixed to the ground, and the support base is fixed to the fixed base plate via a column. Two drive motors 25 are mounted on the support base, and drive screws 26 are mounted on the output shafts of the drive motors 25. The two drive screws 26 are threadedly connected to both ends of the fixed platform 15.

[0055] The procedure for using this device is as follows:

[0056] In use, the fixed base 14 of the tension application mechanism is firmly installed on the ground by anchor bolts or other fixing methods to ensure its stability; the disc buckle support rod 1 is erected directly above the tension application mechanism, and the two sides of the disc buckle support rod 1 are connected to the vertical support rod by the disc buckle connector, and the tension application mechanism is connected to the disc buckle support rod 1 by the connecting clamp 24.

[0057] Adjust the height of the support frame 11, install the support tube 2 of the deformation detection mechanism on the disc buckle support rod 1 through the support frame 11, and attach and fix the connecting strip 5 to the disc buckle support rod 1 to ensure that the guide tube 3 is horizontally positioned directly above the detection tube 4 and that the support tube 2 and the guide tube 3 are parallel.

[0058] Control the winding motor to first tighten the detection line 9, and then release part of the detection line 9 so that the detection line 9 in the connecting channel is loosened and a little slack is maintained so that it can be quickly released when deformed;

[0059] Start the drive motor 25 on the fixed base 14, and make preliminary adjustment of the height of the fixed platform 15 through the drive screw 26, so that the tension application mechanism is tightly connected to the disc buckle support rod 1;

[0060] The tensioning motor 13 is started, which drives the drive rod 16 to rotate through the connecting worm gear 17 and the connecting worm wheel 18. This, in turn, drives the connecting gear 19 to rotate. The connecting gear 19 meshes with the rack 21 of the drive amplification assembly, causing the two wedge blocks 20 to move relative to each other. The inclined bottom surface of the wedge block 20 acts on the connecting frame 22, pulling the connecting arm 12 downward, thereby applying tension to the disc buckle support rod 1. During the application of tension by the tensioning mechanism, the disc buckle support rod 1 will deform, increasing the distance between the detection tube 4 and the guide tube 3. The length of the detection line 9 increases with the increase in deformation, and the resistance of the detection circuit increases accordingly. The resistance detector monitors the resistance change in real time and transmits the data to the controller. At the same time, the pressure sensor monitors the tension applied to the disc buckle support rod 1 by the tensioning mechanism and also transmits the data to the controller. Finally, the deformation position and deformation amount of the disc buckle support rod 1 under a certain load condition can be obtained.

[0061] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
