Description

Technical Field

[0001] This utility model belongs to the field of carbon fiber cable anchor technology, and in particular relates to an intelligent prestressed carbon fiber cable anchor. Background Technology

[0002] Intelligent prestressed carbon fiber cable anchors are devices used to anchor carbon fiber cables and apply prestress, and they have important applications in fields such as building structure reinforcement.

[0003] Although carbon fiber cable materials have a significant advantage in tensile strength compared to other materials, their application in construction still faces considerable limitations. When the stress approaches the upper limit and is not addressed promptly, it can easily lead to major accidents, thus causing conventional carbon fiber cable anchors to be unable to provide data feedback to intelligent devices.

[0004] To address these issues, we propose an intelligent prestressed carbon fiber cable anchor. Utility Model Content

[0005] The purpose of this invention is to solve the problem that conventional carbon fiber cable anchors cannot provide data feedback to intelligent devices, and to propose an intelligent prestressed carbon fiber cable anchor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart prestressed carbon fiber cable anchor includes a guide frame, with a sliding bolt movably inserted inside the guide frame. A bolt is threaded onto the upper part of the sliding bolt. A pressure sensor is positioned between the guide frame and the bolt, embedded within the guide frame. The target carbon fiber cable is placed between the guide frame and the sliding bolt. The bolt is tightened using a wrench, and the bolt acts on the pressure sensor, causing the bolt to slide outwards. The guide frame guides the sliding bolt downwards, clamping and securing the target carbon fiber cable. A screw is passed through the sliding bolt and installed on the building. When the target carbon fiber cable is subjected to force, it pulls the sliding bolt, causing the guide frame to further guide the bolt downwards, further clamping the target carbon fiber cable. This loosens the bolt, causing the pressure sensor to collect a smaller pressure reading. When the pressure reading falls below a threshold, an alarm is triggered by a smart device, providing data to the smart device when the sliding bolt is subjected to excessive tension.

[0008] Preferably, a metal nail is inserted inside the guide frame. After the target carbon fiber cable is placed between the guide frame and the sliding bolt, the metal nail is passed through the guide frame and the target carbon fiber cable, and the tip of the metal nail is bent to increase the stability of the front structure of the guide frame.

[0009] Preferably, the guide frame includes a frame body, a guide block is fixedly connected inside the frame body, an insertion port is provided at the rear of the frame body, and a clamping block is fixedly connected to the rear of the frame body. The insertion port and clamping block accommodate the pressure sensor, facilitating the assembly of the guide frame and the pressure sensor together.

[0010] Preferably, the upper end of the frame has a groove. The groove accommodates the sharp tip of the metal nail, preventing injury.

[0011] Preferably, the sliding bolt includes a compression plate and a pull plate. The compression plate is in movable contact with the guide block, and the pull plate is fixedly connected to the rear of the compression plate. The pull plate slides through the frame, and a nut is fixedly connected to the upper end of the pull plate. The bolt is threaded into the nut. After the bolt is tightened, the bolt drives the nut to act on the pull plate, which in turn pulls the compression plate. The guide block guides the compression plate to press against the target carbon fiber cable, facilitating adaptive tightening of the target carbon fiber cable.

[0012] Preferably, the sliding bolt further includes an extension block, which is fixedly connected to the side end of the extrusion plate. The extension block increases the range of action between the sliding bolt and the target carbon fiber cable.

[0013] Preferably, the pressure sensor includes a sensor body, one end of which is fixedly connected to a spring block. The sensor body and the spring block are inserted into a socket and a clamp. After the bolt is tightened, it presses against the sensor body. The sensor body acts on the spring block, and the force after installation is recorded. An external intelligent device detects the pressure of the bolt on the sensor body through the sensor body, and indirectly determines the outward pulling amplitude of the sliding bolt through the bolt, which facilitates indirect determination of the tension on the sliding bolt and the target carbon fiber cable.

[0014] In summary, the technical effects and advantages of this utility model are as follows: 1. The target carbon fiber cable is placed between the guide frame and the sliding bolt. The bolt is tightened with a wrench. The bolt acts on the pressure sensor, causing the bolt to slide outward. The guide frame guides the sliding bolt downward, clamping and fixing the target carbon fiber cable. After the screw is installed on the building, when the target carbon fiber cable is pulled by force, the guide frame further guides the sliding bolt downward, thereby further clamping the target carbon fiber cable. This causes the bolt to loosen the pressure sensor, resulting in a smaller pressure data collected by the pressure sensor. When the small data exceeds the threshold, an alarm is issued through the intelligent device, which conveniently provides data to the intelligent device when the sliding bolt is subjected to excessive tension.

[0015] 2. After placing the target carbon fiber cable between the guide frame and the sliding bolt, pass the metal nail through the guide frame and the target carbon fiber cable, and bend the tip of the metal nail to increase the stability of the front structure of the guide frame.

[0016] 3. After tightening the bolts, the bolts drive the nuts to act on the pull plate, which in turn pulls the extrusion plate. The guide block guides the extrusion plate to press against the target carbon fiber cable, facilitating adaptive compression of the target carbon fiber cable.

[0017] 4. After tightening the bolt, press the bolt onto the sensor body. The sensor body acts on the elastic block, and the force after installation is recorded. The external intelligent device detects the pressure of the bolt on the sensor body through the sensor body, and indirectly judges the outward pulling range of the sliding bolt through the bolt, which facilitates the indirect judgment of the tension on the sliding bolt and the target carbon fiber cable.

[0023] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0024] like Figure 1 As shown, an intelligent prestressed carbon fiber cable anchor includes a guide frame 2, a sliding bolt 3 is movably inserted inside the guide frame 2, a bolt 5 is threaded on the upper part of the sliding bolt 3, and a pressure sensor 4 is provided between the guide frame 2 and the bolt 5, with the pressure sensor 4 embedded inside the guide frame 2.

[0025] like Figure 1 As shown, a metal nail 1 is inserted inside the guide frame 2. After placing the target carbon fiber cable between the guide frame 2 and the sliding bolt 3, the metal nail 1 is passed through the guide frame 2 and the target carbon fiber cable, and the tip of the metal nail 1 is bent.

[0026] like Figure 1 and 2As shown, the guide frame 2 includes a frame 21, a guide block 22 is fixedly connected inside the frame 21, an insertion port 23 is provided at the rear of the frame 21, and a clamping block 24 is fixedly connected at the rear of the frame 21. The pressure sensor 4 is accommodated by the insertion port 23 and the clamping block 24.

[0027] like Figure 2 As shown, a groove 25 is provided at the upper end of the frame 21. The groove 25 is used to accommodate the tip of the metal nail 1.

[0028] like Figure 1 and 3 As shown, the sliding bolt 3 includes a compression plate 31 and a pull plate 32. The compression plate 31 is in movable contact with the guide block 22. The pull plate 32 is fixedly connected to the rear of the compression plate 31 and slides through the frame 21. A nut 33 is fixedly connected to the upper end of the pull plate 32, and a bolt 5 is threaded into the nut 33. After tightening the bolt 5, the bolt 5 drives the nut 33 to act on the pull plate 32, which in turn pulls the compression plate 31. The guide block 22 guides the compression plate 31 to press against the target carbon fiber cable.

[0029] like Figure 1 and 3 As shown, the sliding bolt 3 also includes an extension block 34, which is fixedly connected to the side end of the extrusion plate 31. The extension block 34 is used to increase the range of action between the sliding bolt 3 and the target carbon fiber cable.

[0030] like Figure 1 , 2 As shown in Figure 4, the pressure sensor 4 includes a sensor body 41, with a spring block 42 fixedly connected to one end of the sensor body 41. The sensor body 41 and the spring block 42 are inserted into the socket 23 and the clamping block 24. After tightening the bolt 5, the bolt 5 presses onto the sensor body 41, and the sensor body 41 acts on the spring block 42. The force after installation is then recorded. An external intelligent device detects the pressure of the bolt 5 on the sensor body 41 through the sensor body 41, and indirectly determines the outward pulling amplitude of the sliding bolt 3 through the bolt 5.

[0031] Working principle: The target carbon fiber cable is placed between the guide frame 2 and the sliding bolt 3. The bolt 5 is tightened with a wrench. The bolt 5 acts on the pressure sensor 4, causing the bolt 5 to move the sliding bolt 3 outward. The guide frame 2 guides the sliding bolt 3 downward, clamping and fixing the target carbon fiber cable. After the screw is installed on the building, when the target carbon fiber cable is pulled by force, the guide frame 2 further guides the sliding bolt 3 downward, causing the sliding bolt 3 to clamp the target carbon fiber cable even tighter. This causes the bolt 5 to loosen the pressure sensor 4, resulting in a decrease in the pressure data collected by the pressure sensor 4. When the small data exceeds the threshold, an alarm is issued through the intelligent device, providing data to the intelligent device when the sliding bolt 3 is subjected to excessive tension.

Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the utility model, based on the technical solution and the inventive concept of the utility model, should be included within the scope of protection of the utility model.

[0033] The description briefly mentions the application direction of the utility model in relation to existing technologies known to those skilled in the art without modification, and combines them with the utility model to form a complete technology; it avoids excessive popularization of technologies known to those skilled in the art, in order to help those skilled in the art quickly understand the main content of the utility model.
