Description

Technical Field

[0001] The present invention relates to the technical field of intelligent monitoring equipment in building construction, and in particular to a steel sleeve connection torque and displacement dual-control intelligent monitoring vibration reminder device and a use method thereof. Background Art

[0002] In the field of construction engineering, the connection between steel bars is a key link to ensure the strength and stability of the structure. Among them, steel sleeve connection, as a widely used mechanical connection method, plays a vital role in bridges, high-rise buildings, large-scale infrastructure and other projects due to its advantages such as high connection strength and convenient construction. However, the existing steel sleeve connection technology still faces a series of challenges in its implementation, especially in the control and monitoring of connection quality.

[0003] Traditional steel sleeve connections mostly rely on manual experience and simple torque detection methods. Operators usually use wrenches to tighten the steel bars and sleeves, and rely on personal experience to judge whether the connection meets the technical standards. This method is not only inefficient, but also has great subjectivity and errors, and it is difficult to ensure that each connection meets the torque value and steel bar insertion depth required by the design. According to the strict regulations of the "Technical Code for Mechanical Connection of Steel Bars" (JGJ107-2016), after the installation of the steel bar straight thread joint, the thread heads should be tightened against each other in the center of the sleeve, and the exposed threads on one side should not exceed 2P complete threads (P is the pitch). This standard further emphasizes the importance of connection accuracy. However, in the actual construction process, operators need to constantly bend down to check the connection status of the steel bar and the sleeve, which is not only time-consuming and labor-intensive, but also difficult to ensure the accuracy and consistency of the judgment.

[0004] In addition, traditional torque wrenches only have the function of torque measurement and cannot simultaneously monitor the depth of the steel bar inserted into the sleeve. Since insufficient or excessive steel bar insertion depth may affect the stability and reliability of the connection, it is one-sided to judge whether the connection is completed based solely on the torque value, which may result in the connection quality not being fully guaranteed. This situation not only increases the safety hazards during the construction process, but may also have an adverse effect on the overall structural strength of the building.

[0005] In view of the above problems, the industry urgently needs an intelligent monitoring device that can simultaneously monitor the torque value and the displacement of the steel bar insertion, so as to achieve a comprehensive and accurate judgment of the connection status of the steel sleeve. Through intelligent monitoring means, the errors and uncertainties of manual operations can be reduced, the accuracy and reliability of the connection can be improved, and the construction quality and safety can be guaranteed. It is in this context that the present invention came into being, aiming to realize the dual-control intelligent monitoring and vibration reminder of the torque and displacement of the steel sleeve connection by integrating torque sensors, displacement sensors and advanced PID control systems, so as to promote technological progress and innovative development in the field of construction engineering.

[0030] Example 4 In another preferred embodiment, based on the above-mentioned embodiments 1, 2, and 3, this embodiment provides a specific implementation of a steel sleeve connection torque and displacement dual-control intelligent monitoring vibration reminder device.

[0031] First, input the connection specification parameters; users need to input the target thread length according to the project requirements and the actual conditions of the steel bars and sleeves. (For example, set to 30mm), the diameter of the steel bar (For example, set it to 25mm), sleeve model (matching the diameter of the steel bar, such as selecting a sleeve corresponding to a steel bar with a diameter of 25mm), material (such as low carbon steel), and connection strength requirements (such as reaching 95% of the design strength).

[0032] Next, the system automatically matches and configures the PID control strategy based on the input specification parameters; in this step, the system sets the proportional gain of the PID controller based on the rebar diameter, sleeve model, material and connection strength requirements. , integral gain and differential gain ; These parameters are set to optimize control performance and ensure that the connection process is both fast and accurate. For example, you can set is 1.2, is 0.5, is 0.3, these values ​​can be adjusted according to actual conditions.

[0033] Then, the equipment is prepared and calibrated; in this step, the system will perform accuracy verification on the torque sensor 4 and the displacement sensor 5 to ensure that the measurement error is within an acceptable range.

[0034] After starting the connection device, the sensor module starts to collect data in real time; the torque sensor 4 monitors the torque value applied by the wrench , the displacement sensor monitors the actual thread length of the steel bar inserted into the sleeve ; These data are transmitted to the PID controller 7 for processing in real time.

[0035] Based on the preprocessed data, the system evaluates the current connection status and calculates the deviation between the actual thread length and the target thread length. , and set the torque threshold according to the material and connection strength requirements ;if If ΔL is within the allowable range (for example, the allowable deviation is set to ±1mm), the connection status is considered to meet the requirements.

[0036] If the connection status does not meet the requirements, the PID controller will calculate the adjustment amount according to the PID control algorithm, that is, the torque adjustment amount ; This calculation process takes into account the current deviation, the historical deviation change trend and the three key parameters of the PID controller 7; then, the calculated adjustment amount is converted into a specific control instruction and sent to the display screen 9 to remind the operator to proceed to the next step.

[0037] During the connection process, the system continuously performs deviation detection, PID algorithm calculation and control instruction output to form a closed-loop control; through continuous adjustment, the system can dynamically adapt to various changes in the connection process to ensure that the connection process is always in the best state.

[0038] When both the torque value and the displacement value reach the preset requirements, the PID controller 7 sends a signal to the vibration reminder component. After receiving the signal, the vibration reminder component immediately emits an audible and visual reminder to remind the worker that the operation is complete. If the connection does not meet the standard, the vibration reminder will not be triggered, and the worker needs to continue the operation until the connection meets the requirements.

[0039] Example 5 In another preferred embodiment, based on the above-mentioned embodiments 1, 2, 3, and 4, this embodiment provides another specific implementation of the steel sleeve connection torque and displacement dual-control intelligent monitoring vibration reminder device.

[0040] Similar to Example 4, this example also first performs steps such as inputting connection specification parameters, system matching and configuring PID control strategy, equipment preparation and calibration; the difference is that this example provides multiple different PID control strategy configuration schemes for different types of steel bars and sleeves.
