Description

Technical Field

[0001] This utility model relates to the technical field of tension testing devices, and in particular to a tension testing device for carbon fiber cloth. Background Technology

[0002] Carbon fiber cloth is a material made from high-strength, high-modulus carbon fiber filaments through a weaving process. It possesses advantages such as lightweight, high strength, high rigidity, corrosion resistance, and fatigue resistance. Carbon fiber cloth is commonly used for tensile, shear, and seismic reinforcement of structural components and is widely applied in fields such as construction, aerospace, automotive, and sporting goods.

[0003] Carbon fiber cloth is mainly used in the construction engineering field for structural reinforcement, seismic reinforcement, crack repair, and protective treatment. It can effectively improve the load-bearing capacity, seismic performance, and durability of buildings. It is suitable for the reinforcement and renovation of concrete structures, bridges, tunnels, etc., and effectively improves the bending, shear, and seismic resistance of concrete. Before using carbon fiber cloth, a tension test is required to accurately determine key mechanical properties such as tensile strength, elastic modulus, and elongation at break. Currently, the commonly used method for carbon fiber tension testing is to vertically clamp the carbon fiber cloth and apply tension in two directions, vertically upward and vertically downward, to test the tension of the carbon fiber cloth. However, this method is not convenient for operators to use and it is difficult to accurately adjust the force generated by the tension of the carbon fiber cloth. In addition, the commonly used clamp structure is usually narrow, which can easily cause uneven deformation of the carbon fiber cloth during the test, making it difficult to obtain accurate and effective carbon fiber cloth tension test data. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a tension force detection device for carbon fiber cloth that is tensioned horizontally and has uniform clamping force.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a base plate, two sets of fixed seats disposed on the base plate, each fixed seat being slidably connected to a slide, one end of each fixed seat being provided with a tension adjustment device, and a clamping assembly disposed on the slide, the movable end of the tension adjustment device being provided with a tension sensor, the other end of the tension sensor being fixedly connected to the slide, one end of the fixed seat forming a mounting plate, the mounting plate being fixedly connected to the tension adjustment device, each slide being provided with a tension detection element, and each slide being correspondingly provided with a push block that cooperates with the corresponding tension detection element.

[0006] Furthermore, the clamping assembly includes a clamping drive device, two sets of transmission plates, two sets of rotating plates, and two sets of pressing plates. The clamping drive device is fixedly connected to the slide block. Each transmission plate is correspondingly disposed at one end of the clamping drive device. Each rotating plate is rotatably connected to one side of the corresponding transmission plate. Each pressing plate is correspondingly connected to the corresponding rotating plate.

[0007] Furthermore, the rotating plate is provided with a rotating column and a stop block. The rotating column is located in the middle of the rotating plate and is rotatably connected to one end of the transmission plate. The stop block is located on one side of the rotating plate and is in a limiting fit with the transmission plate. The rotating plate is provided with a plurality of through holes, all of which are connected to the pressing plate.

[0008] Furthermore, the pressing plate is provided with a plurality of connecting rods and a pressure plate. The pressure plate is connected to one end of the plurality of connecting rods. The plurality of connecting rods are slidably engaged with the corresponding through holes. One end of each connecting rod is provided with a locking element for fixing. The contact surface between the pressure plate and the carbon fiber cloth is formed with anti-slip texture.

[0009] Furthermore, the slide is provided with two sets of fixing plates, a support plate, and a connecting plate. Both sets of fixing plates are fixedly connected to the base plate. The support plate is fixedly connected to the upper part of the two sets of fixing plates. The connecting plate is fixedly connected between the two sets of fixing plates and is also fixedly connected to the base plate.

[0010] Furthermore, a slide rail is formed on the upper surface of the support plate, the slide rail is slidably engaged with the slide block, and the push block is disposed on one side of the slide rail.

[0011] Furthermore, the movable end of the tension adjustment device is provided with a locking block, the locking block forming a locking slot, and the tension sensor is provided with a latching rod that cooperates with the locking slot.

[0012] The beneficial effects of this utility model are as follows: Because this utility model uses a tension sensor positioned between the slide and the tension adjustment device, it can directly detect and transmit the tension data in real time to an external data processing mechanism during the tensioning of the carbon fiber cloth, facilitating the formation of a tension change curve. The tension detection component positioned on the outside of the slide, in conjunction with the push block fixed on the fixed base, displays the tension data intuitively during movement, allowing staff to adjust the tension changes promptly and avoid excessive tension changes affecting the detection effect, thus improving the effectiveness of data acquisition. The clamping plate of the clamping assembly uses a planar structure to clamp the carbon fiber cloth, and with its anti-slip textured design, it presses and fixes the carbon fiber cloth under the pressure of the clamping drive device. The large area of ​​the clamping plate ensures uniform clamping force when clamping the carbon fiber cloth, reducing uneven force distribution that could lead to excessive stress on a single point of the carbon fiber cloth, resulting in breakage and improving experimental accuracy.

[0026] The working principle of this utility model:

[0027] The carbon fiber cloth is fed between two adjacent pressure plates 542. The rotating plate 53 is moved to make the pressure plates 542 pre-press the carbon fiber cloth. Then the clamping drive device 51 is activated and the two transmission plates 52 move closer to each other. The rotating plate 53 rotates and the two clamping plates 54 clamp and fix one end of the carbon fiber cloth.

[0028] After the fixation is completed, the two symmetrical tension adjustment devices 4 drive the slide block 3 to move backward, while pulling the carbon fiber cloth.
