Abstract
Description
Technical Field
[0001] This utility model belongs to the field of torque force detection technology, and in particular relates to a device for detecting the torque force of reinforcing bars. Background Technology
[0002] In construction engineering, torque testing is required for mechanical connections of reinforcing bars (such as straight thread connections). A torque wrench is typically used for this testing, as it measures the torque applied to tighten the rebar joint. The general procedure is to first set the torque value on the wrench, then place the wrench on the rebar joint, and steadily rotate the wrench. When a "click" sound is heard or the set torque value is reached, the torque value is recorded.
[0003] Utility model patent with publication number CN210210192U discloses a rebar torque wrench, including a lever installed inside a pipe shell. The lever is installed inside the pipe shell via a pin shaft. One end of the lever extends out of the pipe shell and connects to the jaws of the wrench. The other end of the lever extends into the pipe shell and connects to an impact block. The impact block and a clamping plate are connected by a connecting rod. The two ends of the connecting rod are respectively hinged to the impact block and the clamping plate. The impact block and the clamping plate are respectively machined with inclined surfaces for sliding between them. The contact surfaces between the impact block and the clamping plate are the inclined surfaces and the end faces. The clamping plate is provided with rollers for sliding along the axial direction of the pipe shell. The tail of the clamping plate is connected to the tail of the pipe shell by a spring.
[0004] While this technology, through its mechanical structure, allows for the determination of the wrench's load limit, thus protecting the wrench and extending its lifespan, and can be used in various mechanical installations, large-scale construction projects involve a significant workload in connecting reinforcing bars. Each connection point requires individual torque testing, and manual operation is not only time-consuming and labor-intensive but also incurs high labor costs. This is especially true when the construction site is large or there are numerous reinforcing bar connections, where the cost and risk of manual measurement and operation increase significantly. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned technical problems by providing a steel bar torque force detection device that can effectively replace manual inspection methods, reduce labor costs, improve inspection efficiency, and enhance structural safety.

[0015] In any of the above technical solutions, the rebar torque wrench further includes a clamping mechanism for precisely clamping the rebar connection to ensure that the torque force is applied to the correct position.
[0016] In any of the above technical solutions, the clamping mechanism further includes:

[0018] A pin is positioned between the rebar torque wrench and the connecting plate;
[0019] The stationary jaws are mounted on the connecting plate.
[0020] The movable groove is formed on the stationary jaws and extends through the stationary jaws;
[0021] The lever is positioned within the movable groove of the stationary jaws.
[0022] The movable jaws are rotatably mounted on the lever;

[0024] The rotating shaft is rotatably positioned between two fixed plates.
[0025] A connecting sleeve is provided on the rotating shaft;
[0026] Pull plate, set on the connecting sleeve;
[0027] The bracket is installed on top of the support platform;
[0028] The grip is mounted on the stand.
[0029] The brake lever is rotated and mounted on the handle.
[0030] The pull rope has one end connected to the brake handle and the other end connected to the pull plate.
[0031] The spring is mounted on the lever and located inside the moving jaws.
[0032] In any of the above technical solutions, furthermore, the static jaws and the moving jaws are provided with teeth on their opposing surfaces.
[0033] In any of the above technical solutions, the support platform is further provided with a base frame at the bottom, and the base frame is provided with an adjustment mechanism for adjusting the height of the support platform. Universal wheels are provided around the bottom of the base frame.
[0034] In any of the above technical solutions, the adjusting mechanism further includes:
[0035] Guide housings are located on both sides of the top of the base frame;
[0036] The telescopic shell is slidably set inside the guide shell, with one end of the telescopic shell extending out of the guide shell, and the telescopic shell is connected to the support platform;
[0037] Guide grooves are formed on the guide housing;
[0038] The slide plate is mounted on the telescopic shell, and extends out of the guide groove and is slidably connected to the guide groove;
[0039] The frame is located on both sides of the base frame;
[0040] The motor is mounted on the frame;
[0041] The ball screw is mounted on the motor output shaft, and the slide plate is connected to the ball screw by a thread.
[0042] In any of the above technical solutions, furthermore, positioning mechanisms are provided on both sides of the base frame, and the positioning mechanisms include:
[0043] The screw, with threads, is located on both sides of the base frame;
[0044] The throttle is mounted on the screw.
[0045] The brake seat, located at the bottom of the screw, is used to increase the friction between the brake and the ground, making the caster wheel less likely to move.
[0046] The beneficial effects of this utility model are:
[0047] 1. The electric drive unit drives the rebar torque wrench to apply the preset torque force. The torque sensor monitors the torque value in real time and transmits the measurement data to the control unit. The control unit determines whether the applied torque value has reached the set requirement based on the data from the torque sensor. After the test is completed, the data storage module automatically records the torque data and date of the test. This enables automatic measurement and application of the preset torque force, precise control of the torque application process, and ensures that the rebar connection meets the torque force standard required by the design.
[0048] 2. Press the brake handle. The brake handle pulls the rope, and the pull plate applies force to the rotating shaft through the connecting sleeve, thereby driving the lever to rotate, which in turn drives the moving jaws to open, and the spring deforms. Place the stationary jaws at the rebar connection point, release the brake handle, and under the reset action of the spring, the movement of the lever drives the moving jaws to move closer to the stationary jaws until the moving jaws clamp the rebar connection point. This quickly realizes the clamping, adjustment and release operation, which greatly improves the efficiency and accuracy of the inspection process, while also ensuring user safety and ease of use.
[0049] 3. The teeth can effectively increase the friction between the static jaws and the moving jaws, ensuring that the steel bar will not slip or shift during the inspection process. This allows the two ends of the steel bar to be firmly clamped when torque is applied, preventing the steel bar from slipping or shifting position due to the force during the inspection process, thus making the measurement of torque more accurate.
[0050] 4. The motor drives the ball screw to rotate, causing the slide to move the telescopic shell in a straight line inside the guide shell, thereby adjusting the height of the support platform to meet the different height requirements in the process of testing the torque force of steel bars, and improving the flexibility, ease of operation and testing accuracy of the testing device.
[0051] 5. By increasing the friction between the brake seat and the ground, the slippage or rotation of the casters can be effectively prevented, thereby ensuring the stability of the device and preventing the casters from moving unintentionally during the testing process, so as not to affect the measurement results.

Detailed Implementation
[0058] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0059] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0060] Example 1:
[0061] like Figure 1 , Figure 2 and Figure 5 As shown, this embodiment provides a rebar torque force detection device, including:
[0062] Support platform 1;
[0063] The rebar torque wrench 2 has multiple components and is located on the support platform 1;
[0064] The torque sensor 3 is located at the end of the rebar torque wrench 2. The torque sensor 3 can measure the torque value applied to tighten the rebar connection and is used to detect the applied torque force at the rebar connection.
[0065] Electric drive unit 4 is mounted on support platform 1. Electric drive unit 4 provides power to apply force to the end of rebar torque wrench 2. It is used to drive rebar torque wrench 2 to rotate the rebar connection part or apply a preset torque force. It can automatically control the applied torque according to the detection requirements.
[0066] Control unit 5 is used to receive torque data output by torque sensor 3 and control the working state of electric drive unit 4 to ensure that the torque force reaches the set value.
[0067] Display interface 6 is used to display torque detection results in real time and provide data analysis and feedback functions;
[0068] The data storage module 61 is used to store the records of each rebar torque test and can export and analyze the data.
[0069] In this technical solution, the device can automatically measure and apply a preset torque force, precisely control the torque application process, and ensure that the torque force at the rebar connection meets the design requirements. It displays the torque detection results in real time, monitors whether the applied torque force reaches the set value, and provides feedback. If the torque force does not meet the set requirements, the device will issue an alarm or prompt to avoid construction quality problems caused by detection errors. The control unit 5 automatically adjusts the output power of the electric drive unit 4 based on the measurement data from the torque sensor 3, accurately applying the required torque force. No manual intervention is required, ensuring the accuracy and stability of the torque. The device's data storage module 61 records data from each torque detection, forming a detailed detection record. It also supports data export and analysis, facilitating subsequent quality control, auditing, and construction progress management. Automated operation reduces manual inspection time and human error, and can complete a large number of rebar connection point inspections in a shorter time, improving construction progress and efficiency. By reducing manual operation, especially the need for prolonged high-intensity physical labor, the device can effectively reduce safety hazards caused by fatigue or incorrect operation of personnel on the construction site.
[0070] Workflow: The user first starts the rebar torque detection device. Upon startup, the system performs a self-check to ensure all components (such as the electric drive unit 4, torque sensor 3, display interface 6, etc.) are in normal working condition. The control unit 5 initializes according to the set standard operating parameters (such as the preset torque value, detection mode, etc.). Before installing and connecting the rebar, the construction personnel accurately locate the rebar connection point and align the rebar torque wrench 2 with the connection point. The electric drive unit 4 starts working, driving the rebar torque wrench 2 to apply the preset torque force. The electric drive unit 4 can adjust the output power in real time based on the feedback from the torque sensor 3 to ensure that the applied torque is always kept within the target range. The torque sensor 3 monitors the torque value in real time and transmits the measurement data to the control unit 5. The control unit 5 determines whether the currently applied torque value has met the set requirements based on the data from the torque sensor 3. If the torque force reaches the preset value, the system displays "Detection passed" and stops applying torque; if the torque force is too high or too low, the system will give an alarm or prompt through the display interface 6, requiring corresponding adjustments. After each test, the device automatically records the torque data, date, and personnel involved, storing this information in the data storage module 61. The data can be viewed through the display interface 6 and can be exported for subsequent analysis and quality control. Upon completion of the test, the system prompts the user to finish the torque force test at that connection point, allowing the user to move the wrench to the next rebar connection point. The entire testing process continues until all rebar connections are tested. In engineering projects, managers or quality control personnel can query, statistically analyze, and process historical test data through the data storage module 61. The system can automatically generate test reports, analyzing the pass rate, average torque force, and deviation for each test, providing a reference for construction quality.
[0071] By adopting the above workflow, the device not only improves the efficiency and accuracy of torque detection at rebar connections but also reduces the risks and errors associated with manual operation. Automated control allows the device to quickly adapt to different testing needs and construction environments, optimize the allocation of construction resources, ensure that rebar connections meet design requirements, and significantly improve the level of construction quality control. Simultaneously, data storage and analysis provide a scientific basis for subsequent quality control and construction progress management, ensuring the safety and efficiency of the project.
[0072] like Figure 1 and Figure 2 As shown, in this embodiment, the optimized display interface 6 is a touch screen, which can display real-time data, provide operation guidance, and support parameter setting, detection record query and result export through the interface.
[0073] In this technical solution, the user installs the rebar into the testing equipment and ensures that all parts of the equipment are correctly connected. Through the touchscreen interface, the user checks the equipment status to ensure it is working properly. If the equipment is not ready, the interface will display relevant warning information. On the touchscreen interface, the user sets the testing parameters as needed (such as upper and lower limits of torque, sampling frequency, etc.). After setting, clicking the "Confirm" button will apply these parameters. Clicking the "Start Testing" button on the touchscreen begins real-time monitoring of the rebar torque. During this process, real-time data is displayed on the touchscreen, allowing the user to view the torque values at any time and adjust parameters or check the equipment status as needed. The equipment continuously collects data and displays real-time test values. The user can view historical data, waveform curves, etc., on the touchscreen. If the equipment has a pre-set warning value (e.g., torque over-limit), the touchscreen will display a warning and prompt the user to take action when the test value reaches the preset threshold. After the test is completed, the user can query the test records through the touchscreen interface to view detailed data for each test. The query interface allows filtering by time period, parameters, etc. After the test results meet the requirements, the user can choose to export the data and save it to a USB flash drive, cloud storage, or other storage devices. After the data is exported, the system will generate a report and save historical data for later review or analysis. After the test is complete, the user can turn off the device via the touchscreen, and the device will enter standby mode, displaying the message "Device turned off" on the touchscreen.
[0074] Example 2:
[0075] This embodiment provides a rebar torque force detection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0076] like Figures 1-3 As shown, in this embodiment, the optimized rebar torque wrench 2 also includes a clamping mechanism 7 for precisely clamping the rebar connection part to ensure that the torque force is applied to the correct position.
[0077] In this technical solution, the clamping mechanism 7 is designed to ensure that the rebar torque wrench 2 can accurately position and clamp the rebar connection when applying torque, preventing the torque force from deviating from the target position. This ensures that the applied torque force meets design requirements, guaranteeing sufficient fixation and reinforcement of the rebar connection and ensuring structural safety. The introduction of the clamping mechanism 7 effectively reduces possible slippage, misalignment, or instability during operation, thereby improving the stability and reliability of the entire testing process. This is particularly important on construction sites, reducing human interference with measurement results and ensuring the accuracy of torque force testing. With accurate clamping of the rebar connection, workers can complete the torque force testing and adjustment of the rebar connection more quickly, reducing time wasted due to repeated measurements or readjustments, thus improving construction efficiency. The clamping mechanism 7 can fix the rebar connection, ensuring that the applied torque force is applied under the same conditions each time, avoiding test errors caused by improper clamping or inaccurate positioning, and ensuring the consistency and repeatability of test results.
[0078] like Figures 1-3 As shown, in this embodiment, the optimized clamping mechanism 7 includes:
[0079] The connecting plate 71 is installed inside the rebar torque wrench 2;
[0080] Pin 72 is positioned between the rebar torque wrench 2 and the connecting plate 71;
[0081] The stationary jaw 73 is mounted on the connecting plate 71;
[0082] The movable slot 74 is formed on the stationary jaw 73 and extends through the stationary jaw 73;
[0083] Lever 75 is located in the movable groove 74 of the stationary jaw 73;
[0084] The movable jaw 76 is rotatably mounted on the lever 75;
[0085] Fixed plates 77 are provided on both sides of the outside of the movable jaw 76;
[0086] The rotating shaft 78 is rotatably positioned between two fixed plates 77;
[0087] Connecting sleeve 79 is disposed on rotating shaft 78;
[0088] Pull plate 710 is provided on connecting sleeve 79;
[0089] Bracket 711 is installed on the top of support platform 1;
[0090] The grip 712 is mounted on the bracket 711;
[0091] The brake handle 713 is rotatably mounted on the grip 712;
[0092] The pull rope 714 has one end connected to the brake handle 713 and the other end connected to the pull plate 710;
[0093] The spring 715 is mounted on the lever 75 and located within the moving jaw 76.
[0094] In this technical solution, the user first presses the brake handle 713. When the brake handle 713 rotates, the pull rope 714 pulls the pull plate 710. The pull plate 710 applies force to the rotating shaft 78 through the connecting sleeve 79, thereby driving the lever 75 to rotate, which in turn drives the movable jaw 76 to open, and the spring 715 deforms. Then, the stationary jaw 73 is placed at the rebar connection point. At this time, the movable jaw 76 is in a loose state, and the rebar can be placed freely. After determining the position where the rebar needs to be twisted, the brake handle 713 is released. Under the reset action of the spring 715, the movement of the lever 75 drives the movable jaw 76 to move closer to the stationary jaw 73 until the movable jaw 76 clamps the rebar connection point. At the same time, the movable jaw 76 drives the fixed plate 77 and the pull plate 710 to reset. The spring 715 provides a certain auxiliary elastic force for the clamping action, ensuring a smoother and more precise clamping process. The user can adjust the clamping force by adjusting the degree of rotation of the brake handle 713. Rotating the brake handle 713 causes the pull rope 714 to apply different tensions to the pull plate 710, thereby changing the clamping strength. When the moving jaws 76 are in full contact with the rebar connection, the rebar connection is firmly clamped. At this point, the rebar connection is ready for torque force testing. During clamping, the rebar torque force detection device can accurately apply and measure the torque. After the test, the user can adjust the clamping force or release the clamping mechanism 7 as needed. To release, the user rotates the brake handle 713, releasing the pull rope 714, causing the pull plate 710 to retract, the moving jaws 76 to open, and the rebar connection to be released. This allows for efficient and precise clamping of the rebar connection, ensuring adjustable clamping force and a stable and reliable clamping process. The clamping mechanism 7 can quickly perform clamping, adjustment, and release operations, greatly improving the efficiency and accuracy of the testing process, while also ensuring user safety and ease of use.
[0095] like Figures 1-3 As shown, in this embodiment, the optimized static jaw 73 and the moving jaw 76 are provided with teeth 8 on their opposing surfaces.
[0096] In this technical solution, the reinforcing bar rotates when subjected to torque. The teeth 8 effectively increase the friction between the stationary jaws 73 and the moving jaws 76, ensuring that the reinforcing bar does not slip or shift during testing. This is crucial for the accuracy of the test results. The teeth 8 provide a "biting" mechanism, allowing the two ends of the reinforcing bar to be firmly clamped when torque is applied, preventing the reinforcing bar from slipping or shifting position due to force during testing. The surface of the reinforcing bar is usually quite hard, and the design of the teeth 8 effectively improves the wear resistance of the clamp, thus maintaining stable performance and effectiveness even after long-term use. By enhancing the clamping force, the design of the teeth 8 reduces errors caused by reinforcing bar slippage or unstable clamping, thereby resulting in higher accuracy in measuring torque.
[0097] Example 3:
[0098] This embodiment provides a rebar torque force detection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0099] like Figure 1 and Figure 4 As shown, in this embodiment, the support platform 1 is optimized by having a base frame 9 at its bottom, an adjustment mechanism 10 for adjusting the height of the support platform 1 on the base frame 9, and casters 11 around the bottom of the base frame 9.
[0100] In this technical solution, the height of the support platform 1 is adjusted by the adjustment mechanism 10 according to the height of the reinforcing bar and the testing requirements, ensuring that the support platform 1 is in a suitable position. When it is necessary to change the position or adjust the testing area, the device can be easily moved to a new working position using the casters 11 on the base frame 9. The casters 11 can rotate freely, allowing the device to move flexibly on the horizontal plane without spatial limitations. After the test is completed, the height of the support platform 1 can be readjusted again using the adjustment mechanism 10, or the device position can be adjusted according to the requirements of the working environment. This ensures the height adjustability, stability, and flexibility of the equipment. The adjustment mechanism 10 can adapt to the testing requirements of different reinforcing bars, while the casters 11 provide convenient mobility, making the device suitable for accurate testing of reinforcing bar torque in different operating environments.
[0101] like Figure 1 and Figure 4 As shown, in this embodiment, the optimized adjustment mechanism 10 includes:
[0102] Guide housing 101 is located on both sides of the top of the base frame 9;
[0103] The telescopic shell 102 is slidably disposed inside the guide shell 101, with one end of the telescopic shell 102 extending out of the guide shell 101, and the telescopic shell 102 is connected to the support platform 1.
[0104] Guide groove 103 is formed on guide shell 101;
[0105] The slide plate 104 is mounted on the telescopic shell 102, and the slide plate 104 extends out of the guide groove 103 and is slidably connected to the guide groove 103;
[0106] The frame 105 is located on both sides of the base frame 9;
[0107] Motor 106 is mounted on frame 105;
[0108] The ball screw 107 is mounted on the output shaft of the motor 106, and the slide plate 104 is threadedly connected to the ball screw 107.
[0109] In this technical solution, before use, ensure that all components of the support platform 1 and the adjustment mechanism 10 are in their initial positions, and that the motor 106 and ball screw 107 system are in standby mode. The user starts the motor 106, which rotates, driving the ball screw 107 to rotate. The threaded connection between the ball screw 107 and the slide plate 104 allows the rotation of the ball screw 107 to drive the slide plate 104 to slide along the guide groove 103. The slide plate 104 then drives the telescopic housing 102 to move linearly within the guide housing 101, thereby adjusting the height of the support platform 1. The sliding connection between the guide groove 103 on the guide housing 101 and the slide plate 104 ensures that the telescopic housing 102 will not shift or jam during adjustment. The connection between the telescopic housing 102 and the support platform 1 ensures that the support platform 1 can rise and fall with the movement of the telescopic housing 102 during adjustment, thus changing the height of the support platform 1. When the support platform 1 is adjusted to the desired position, the user turns off the motor 106, the motor 106 stops rotating, and the support platform 1 is fixed at the set height. After adjusting to the appropriate height, the device is ready to test the torque force of the reinforcing bars. If the height needs to be readjusted, the ball screw 107 can be rotated in the opposite direction by restarting the motor 106, thereby driving the slide plate 104 and the telescopic shell 102 to move accordingly, and continuing to adjust the height of the support platform 1. This allows for precise control of the height of the support platform 1, thus meeting the different height requirements during the reinforcing bar torque force test, and improving the flexibility, ease of operation, and testing accuracy of the testing device.
[0110] Example 4:
[0111] This embodiment provides a rebar torque force detection device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0112] like Figure 1 and Figure 4 As shown, in this embodiment, the optimized base frame 9 is provided with positioning mechanisms 12 on both sides, and the positioning mechanism 12 includes:
[0113] Screw 121, with threads on both sides of the base frame 9;
[0114] The throttle 122 is mounted on the screw 121;
[0115] Brake seat 123 is located at the bottom of screw 121. Brake seat 123 is used to increase the friction between the screw and the ground, making the caster wheel 11 less likely to move.
[0116] In this technical solution, the main purpose of the positioning mechanism 12 is to mechanically fix and position the rebar torque force detection device, preventing the caster wheel 11 from moving unintentionally during the detection process. Especially when testing the torque force of rebar, it is necessary to ensure the detection device remains stable to avoid affecting the measurement results. By increasing the friction between the brake seat 123 and the ground, the slippage or rotation of the caster wheel 11 can be effectively prevented, thereby ensuring the stability of the device.
[0117] Workflow: Before use, the positioning mechanism 12 is unlocked, and the casters 11 can rotate and move freely. The user pushes the detection device to the desired position. Due to the free rotation of the casters 11, the device can move smoothly in different directions. Once the device reaches the target position, the user rotates the handle 122, driving the screw 121 to rotate, which in turn moves the brake seat 123 downward, causing it to contact the ground and increase friction. In this way, the brake seat 123 effectively increases the friction with the ground, preventing the casters 11 from moving freely. After sufficient friction is generated between the brake seat 123 and the ground, the casters 11 no longer move easily, and the base frame 9 is firmly fixed. At this point, the overall position of the rebar torque force detection device is stabilized, ensuring that the device does not move unexpectedly during subsequent testing. The fixed device can then begin measuring the rebar torque force. Since the device is stable and the casters 11 no longer rotate, the test results will not be affected by changes in the device's position during the measurement process. After the test is completed, if it is necessary to move the device or change its position, the user only needs to rotate the handle 122 in the opposite direction. The screw 121 rotates, causing the brake seat 123 to rise, reducing the friction between the device and the ground. At this time, the caster wheel 11 resumes free movement, and the user can move the device again.
