Description

Technical Field

[0001] This application relates to the technical field of carbon fiber cloth production equipment, and in particular to an assembled carbon fiber cloth reinforcing tensioning device. Background Technology

[0002] Carbon fiber cloth, also known as carbon fiber cloth, carbon fiber woven cloth, carbon cloth, carbon fiber tape, and carbon fiber sheet, is a unidirectional carbon fiber reinforcement product. It is typically woven from 12K carbon fiber filaments and boasts advantages such as high strength, low density, and thinness. It essentially does not increase the self-weight or cross-sectional dimensions of the reinforced component, making it widely applicable for the reinforcement, repair, seismic strengthening, and structural reinforcement of joints in various structural types and shapes, including buildings, bridges, and tunnels.

[0003] A search revealed that patent document CN221031515U discloses a tensioning device for carbon fiber cloth, including a support frame. The support frame comprises an upper U-shaped frame and a lower U-shaped frame from top to bottom. A connecting frame is fixedly connected to the left end between the upper and lower U-shaped frames. A fixed tensioning seat is fixedly connected to the left side inside the upper U-shaped frame, and a movable tensioning seat is provided on the right side of the fixed tensioning seat. A receiving frame is provided at the top inside the movable tensioning seat. Driving sliders are fixedly connected to both the front and rear sides of the movable tensioning seat. Driving grooves matching the driving sliders are provided on both the front and rear sides inside the upper U-shaped frame. An installation groove is provided through the right end of both the fixed and movable tensioning seats. A clamping groove is provided at the bottom of the installation groove, and a clamping plate is slidably connected inside the installation groove. This device facilitates the tensioning of carbon fiber cloth and can be used to tension carbon fiber cloth of different lengths. It is easy to operate and highly practical.

[0004] In practical applications, it has been found that traditional tensioning devices have significant shortcomings. Their method of fixing carbon fiber cloth is relatively simple, and they can only limit and fix it in a single way. This leads to the problem that the carbon fiber cloth is prone to displacement during tensioning, resulting in a decrease in tensioning accuracy and affecting the reinforcement effect. Therefore, we propose an assembled carbon fiber cloth reinforcement tensioning device to solve the above problems. Utility Model Content

[0005] The purpose of this application is to address the shortcomings of existing technologies, such as the tendency of carbon fiber cloth to shift during tensioning, which leads to a decrease in tensioning accuracy and affects the reinforcement effect. Therefore, this application proposes an assembled carbon fiber cloth reinforcement tensioning device.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: an assembled carbon fiber cloth reinforcement tensioning device, including a base box, two limiting seats are slidably installed on the top of the base box, and a functional box is fixedly installed on the side of the two limiting seats that are far apart from each other. A servo motor is fixedly installed on the left side of the base box, and a bidirectional mechanism is provided between the servo motor and the base box. Two seat holes are opened on the top of the base box. A hydraulic cylinder is fixedly installed on the top of the limiting seat, and the bottom end of the output shaft of the hydraulic cylinder extends into the limiting seat. A limiting mechanism is provided between the bottom end of the output shaft of the limiting seat and the limiting seat. A wire-moving mechanism is provided in the functional box, and a clamping mechanism is provided below the functional box. A first sliding hole is opened on the adjacent side of the two functional boxes, and a second sliding hole and a plate hole are opened at the bottom of the functional box.

The same lead screw is rotatably installed on the inner walls of both sides of the functional box. The lead screw seat is threaded onto the lead screw. The bottom of the lead screw seat extends to the bottom of the functional box. The lead screw seat is slidably connected to the second sliding hole. A gear mechanism is provided between the lead screw and the lifting plate.

[0012] By adopting the above technical solution and by setting up a lead screw mechanism, the lead screw can drive the lead screw seat to move, thereby achieving the purpose of driving the clamping seat to move closer to the limiting seat.

[0013] A further configuration of this application is as follows: the gear mechanism includes a connecting plate, a rack plate, and a gear. Connecting plates are fixedly installed on both sides of the lifting plate. The connecting plates are slidably connected to the corresponding first sliding holes. A rack plate is fixedly installed at the bottom of the connecting plate. A gear is fixedly sleeved on the lead screw. The gear is located inside the lead screw seat. The rack plate meshes with the gear.

[0017] A further feature of this application is that a slide rod is fixedly installed on the top of the lifting plate, the slide rod is slidably connected to the limiting seat, and the slide rod is located outside the hydraulic cylinder.

[0018] By adopting the above technical solution and by setting up a sliding rod, the lifting plate can move more smoothly up and down.

[0019] A further feature of this application is that a controller is provided on the front side of the base box, and the controller is electrically connected to the servo motor.

[0020] By adopting the above technical solution and by setting up a controller, the servo motor can be precisely controlled.
