Description

Technical Field

[0001] This application relates to the field of prefabricated building technology, and in particular to a non-destructive testing device for the connection of prefabricated building structures. Background Technology

[0002] Prefabricated concrete structure is a type of concrete structure that uses prefabricated components as the main load-bearing components and is assembled and connected together. Prefabricated reinforced concrete structure is one of the important directions for the development of building structures in my country. It is conducive to the development of my country's building industrialization, improving production efficiency, saving energy, developing green and environmentally friendly buildings, and improving and ensuring the quality of building projects.

[0003] A patent document with publication number CN218382543U discloses a non-destructive testing device for the joints of prefabricated building structures. The technical solution includes: a detector, a buffer plate, and a threaded block. A sonar is fixedly connected inside the detector, and a telescopic rod is fixedly connected to the other end of the detector. The buffer plate is movably connected to the other end of the telescopic rod. Slide rails are provided on both sides inside the buffer plate, and sliders are slidably installed inside the slide rails. A horizontal plate is fixedly connected to the other end of the telescopic rod between the sliders, and a spring is fixedly connected to the other end of the horizontal plate. This invention, by fixing a sonar inside the detector, allows the device to slide within the slide rails when subjected to impact feedback via the elastic potential energy of the spring. Simultaneously, the telescopic rod extends and retracts within the buffer plate. The potential energy data is then fed back to the device by a sensor, facilitating data reading by operators.

[0004] When using the above devices, the detection mechanism is fixed in place, which makes it impossible to adjust the position of the detection mechanism in the event of some abnormal situations. This makes the device less flexible to use. Furthermore, the display panel and operation buttons lack external protection, resulting in a short service life under harsh external environments. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a non-destructive testing device for the connection of prefabricated building structures, which overcomes the deficiencies of existing technologies. The aim is to solve the problems of the detection mechanism being fixedly installed during use, making it impossible to adjust the position of the detection mechanism in the face of some abnormal situations, resulting in insufficient flexibility in use, and the lack of external protection for the installed display panel and operation buttons, leading to insufficient service life under harsh external environments.

[0006] To achieve the above objectives, this application provides the following technical solution: a non-destructive testing device for the connection of prefabricated building structures, comprising a fixed plate, two sets of movable slots inside the fixed plate, two sets of connectors and connecting bolts on both sides of the fixed plate, a detection mechanism slidably connected inside each of the two sets of movable slots, the detection mechanism comprising a movable plate slidably connected inside the movable slot, a fixed sleeve and a sliding sleeve on one side of the movable plate, the sliding sleeve slidably connected inside the fixed sleeve, a detector at one end of the sliding sleeve, a spring inside the fixed sleeve, an ultrasonic detector in the middle of the fixed plate, a mounting plate and a protective assembly on the front of the fixed plate, a control panel on the front of the mounting plate, the control panel being electrically connected to the detection mechanism and the ultrasonic detector, the protective assembly comprising a protective shell, snap-fit ​​slots on both sides of the protective shell, snap-fit ​​springs inside each of the two sets of snap-fit ​​slots, two sets of snap-fit ​​members on the front of the fixed plate, both sets of snap-fit ​​members engaging with the snap-fit ​​springs.

[0007] By adopting the above technical solution and setting a fixed plate, multiple sets of detection mechanisms can slide inside the moving slot during use. When the fixed plate is installed at the connection of the prefabricated building, the connection condition at the connection can be better detected by moving the position of the detection mechanism. The ultrasonic detector will detect the condition inside the building and cooperate with the detector. The detector will contact the surface of the building, and the deformation force generated will be received by the detector. The received data will be detected by the control panel, so that the detection can be completed quickly from the outside. Moreover, the sliding sleeve and the spring can provide a buffering effect under the action of the spring, and can detect according to the undulations of the building exterior. This can more flexibly realize the detection of building connections and adapt to different working conditions, making it more convenient and stable to use and improving the practicality of the device.

[0008] As a preferred technical solution of this application, the front of the movable plate is provided with four sets of connecting plates, and all four sets of connecting plates are bolted to the fixed plate. One end of the spring is slidably connected to the inside of the sliding sleeve, and the other end passes through the movable plate and is fixedly connected to the limiting component.

[0009] By adopting the above technical solution and setting a connecting plate, a fixed connection between the detection mechanism and the fixed plate can be completed during use. At the same time, the setting limit component can limit the detector to prevent it from falling out, making it more stable during use.

[0010] As a preferred technical solution of this application, the back of the mounting plate is provided with two sets of sliding plates, and the front of the fixing plate is provided with two sets of clamping slide plates and supporting plates, wherein the clamping slide plates and the supporting plates are slidably connected to the sliding plates.

[0011] By adopting the above technical solution and setting a sliding plate, the mounting plate and the fixing plate can be quickly installed and disassembled during use, making it more flexible in use and more convenient for subsequent maintenance and installation.

[0012] As a preferred technical solution of this application, the front of the mounting plate is provided with an audible and visual alarm device, which is electrically connected to the control panel.

[0013] By adopting the above technical solution, the sound and light alarm device can provide sound and light alarm functions during use, and can quickly complete the alarm in case of abnormality.

[0014] As a preferred embodiment of this application, a displacement sensor is provided on the outside of the connecting rod, and the displacement sensor is electrically connected to the control panel.

[0015] By adopting the above technical solution, the displacement sensor can record the travel distance of the detector. When encountering deformation, it can better record the magnitude of the deformation, making it more convenient to use.

[0016] As a preferred technical solution of this application, the front of the protective component is provided with an observation window, the size of which corresponds to the mounting plate.

[0017] By adopting the above technical solution and setting an observation window, the internal operation can be better observed from the outside during use, thus improving the practicality of the device.

[0018] As a preferred technical solution of this application, a battery compartment is provided below the mounting plate, and a spare battery is provided inside the battery compartment.

[0019] By adopting the above technical solution and setting up a battery compartment, the power source can be replaced and can also be used as a backup power source, so that it can still be used in the event of a power outage.

[0020] As a preferred technical solution of this application, the ultrasonic detector is provided at one end of the fixed plate.

[0021] By adopting the above technical solution and through specific settings, the ultrasonic detector can be protected, reducing damage to the ultrasonic detector and extending its service life.

[0022] The beneficial effects of this application are:

[0023] 1. By setting a fixed plate, multiple sets of detection mechanisms can slide inside the moving slot during use. When the fixed plate is installed at the connection of the prefabricated building, the position of the moving detection mechanism can be used to better detect the connection status at the connection. The ultrasonic detector will detect the internal condition of the building and cooperate with the detector. The detector will contact the surface of the building, and the deformation force generated will be received by the detector. The received data will be detected by the control panel, thus enabling rapid detection from the outside. In addition, the sliding sleeve and the spring can provide a buffering effect under the action of the spring, which can detect according to the undulations of the building's exterior. This allows for more flexible detection of building connections and can adapt to different working conditions, making it more convenient and stable to use and improving the practicality of the device.

[0024] 2. By setting a connecting plate, a fixed connection can be completed between the detection mechanism and the fixed plate during use. At the same time, the setting limit component can limit the detector to prevent it from falling out, making it more stable during use. Attached Figure Description

The sliding sleeve 204 and the spring 206 can provide a buffering effect under the action of the spring 206, which can detect according to the undulation of the building. This can more flexibly realize the detection of the building connection and adapt to different working conditions. It is more convenient and stable to use, improving the practicality of the device.
