Description

Technical Field

[0001] The utility model relates to the technical field of tensile strength detection devices, in particular to a geotextile tensile strength detection device. Background Technique

[0002] Geotextile, also known as geotextile fabric, is a water-permeable geosynthetic material made of synthetic fibers by needle punching or weaving. Geotextile is one of the new geosynthetic materials. The finished product is in the shape of a cloth, generally with a width of 4-6 meters and a length of 50-100 meters. Geotextiles are divided into woven geotextiles and non-woven filament geotextiles.

[0003] The tensile strength detection of geotextiles is to measure the ability of geotextile materials to withstand tensile forces and is one of the important indicators for evaluating the performance of geotextiles. Through the tensile strength test, the tensile properties of geotextiles in different directions can be understood, providing an important basis for engineering design. During the test, the geotextile specimen is fixed on the testing machine, a tensile force is applied, and the tensile displacement and the change of the tensile force of the specimen are recorded. Indexes such as the tensile strength and elongation rate of the specimen can be calculated through the test data.

[0004] The prior art patent document with the publication number CN217211936U provides a geotextile tensile strength detection device. After two different geotextiles are freely placed on the initial placement plate respectively, the clamping hydraulic cylinder acts to push the connecting shaft towards the side close to the initial placement plate, so that the clamping block abuts against the geotextile, and one end of the two geotextiles is clamped respectively. At the same time, the secondary positioning member will clamp and position the other ends of the two geotextiles respectively. When both ends of the geotextile are clamped, the control system will turn on the control power supply of the driving member, and the driving member acts, and then the tensile strength detection work of the geotextile can be carried out. When comparing the tensile strength values of two different geotextiles, instead of measuring and recording separately and then comparing, it can be measured and compared at one time, reducing the working time and effectively improving the working efficiency.

[0005] In the above prior art, although the geotextile tensile strength testing device can clamp and fix two different geotextiles through the arrangement of multiple placement plates and clamping structures, and then use the driving component to compare and test the tensile strengths of the two geotextiles, enabling one-time measurement and comparison, reducing the working time and improving the working efficiency. However, when the tensile strength testing device in this patented technology is in use, the two ends of the geotextile are clamped and fixed vertically by the placement plate and the clamping block. Generally, the tensile strength test is carried out by horizontally pulling the geotextile. A relatively large tensile force will be generated during the operation of the device. In this way, the tensile force generated during the testing process is likely to pull out the geotextile. Fixing the geotextile by the method of clamping it vertically by two clamping plates will not be able to hold it when the tensile force reaches a certain level, resulting in the geotextile being pulled out. In this way, accurate tensile strength testing cannot be carried out, which will affect the test results, reduce the fixing stability, and affect the testing accuracy. Therefore, we need a geotextile tensile strength testing device. Summary of the Invention

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, a geotextile tensile strength detection device, including a workbench 1, the bottom of the workbench 1 is fixedly connected with table legs 2, the top of the workbench 1 is equipped with a fixing component 3, and the top of the workbench 1 is provided with a pressing component 6;

[0028] The fixing component 3 includes a fixing frame 301, a first motor 302 is installed on one side of the fixing frame 301, and the output end of the first motor 302 is detachably connected with a rotating roller 303 through a coupling. A hinge 304 is arranged on the outer surface of the rotating roller 303, and an adjusting plate 305 is rotatably connected to one side of the hinge 304. A spring 306 is arranged inside the rotating roller 303, and a threaded rod 307 is rotatably connected inside the fixing frame 301, and a lower pressing plate 308 is arranged at one end of the threaded rod 307;

[0029] The pressing component 6 includes a support frame 601, a second motor 602 is arranged on the top of the support frame 601, and the output end of the second motor 602 is detachably connected with a lead screw 603 through a coupling. A moving plate 604 is rotatably connected to the outer wall of the lead screw 603, and a connecting rod 605 is fixedly connected to the bottom of the moving plate 604. A fixing plate 606 is arranged inside the support frame 601, and one end of the connecting rod 605 is fixedly connected with a pressing block 607.

[0030] Through the above technical solution, manually pass one end of the geotextile through the hole arranged inside the rotating roller 303, lift the adjusting plate 305 by hand to make the geotextile completely pass through the rotating roller 303. The resilience generated by the spring 306 can clamp the adjusting plate 305 and the rotating roller 303, so that the geotextile can be preliminarily fixed. Drive the rotating roller 303 to rotate through the first motor 302, and rotate a part of the geotextile around the rotating roller 303 in a winding state, which can make the geotextile have a preliminary tensioning effect, facilitating subsequent tensile testing. At the same time, the geotextile can be further wound and fixed. Rotate the threaded rod 307 to make the lower pressing plate 308 move downward to press the wound part of the geotextile, which can play a further strengthening role, so that it will not be pulled out randomly during the testing process, greatly increasing the fixing stability and improving the testing accuracy.

[0031] Specifically, a moving mechanism 4 is installed inside the workbench 1, a display body 5 is arranged on the top of the workbench 1, and an equipment door 7 is installed on the front of the workbench 1.

[0032] Through the above technical solution, after manually fixing both ends of the geotextile, start the moving mechanism 4 to move one end of the geotextile to generate a tensile force, and the tensile strength can be detected. The detected result can be displayed on the display body 5, which is convenient for the operator to observe. The equipment door 7 on the front of the workbench 1 can be opened by rotation, which is convenient for disassembling and maintaining the moving mechanism 4 inside the workbench 1.

[0033] Specifically, the fixing frame 301 and the rotating roller 303 form a rotating structure through the first motor 302, and the rotating roller 303 is installed inside the fixing frame 301.

[0034] Through the above technical solution, one end of the geotextile is manually passed through the hole opened inside the rotating roller 303, and the first motor 302 is started to drive the rotating roller 303 to rotate, so that a small part of the geotextile can be wound up, which can achieve the effect of preliminary fixing and tensioning of the geotextile.

[0035] Specifically, the rotating roller 303 and the adjusting plate 305 form a rotating structure through the hinge 304, and the hinge 304 is installed between the rotating roller 303 and the adjusting plate 305. The rotating roller 303 and the adjusting plate 305 form an elastic structure through the spring 306.

[0036] Through the above technical solution, when the geotextile is passed through the hole provided in the rotating roller 303, the adjusting plate 305 is rotated and opened. The adjusting plate 305 rotates through the hinge 304, so that the geotextile can pass through. Then the adjusting plate 305 is released, and the elastic return force generated by the spring 306 makes the adjusting plate 305 automatically retract, which can clamp the geotextile and play a role in preliminary fixing.

[0037] Specifically, the fixing frame 301 and the lower pressing plate 308 form a rotating structure through the threaded rod 307, and the number of the threaded rods 307 is two.

[0038] Through the above technical solution, after the geotextile is wound up and tensioned, the threaded rod 307 is rotated by hand. The rotation of the threaded rod 307 drives the lower pressing plate 308 to move downward, pressing the wound geotextile against the rotating roller 303, which plays a role in further reinforcement.

[0039] Specifically, the second motor 602 and the moving plate 604 form a lifting structure through the lead screw 603, and the shape and size of the outer wall of the lead screw 603 match the shape and size of the inner wall of the moving plate 604.

[0040] Through the above technical solution, the second motor 602 drives the lead screw 603 to rotate, so that the moving plate 604 can move up and down. When the moving plate 604 descends, it can drive the connecting rod 605 to produce a downward pressing effect.

[0041] Specifically, the moving plate 604 and the fixing plate 606 form a sliding structure through the connecting rod 605, and the number of the connecting rods 605 is two. The moving plate 604 and the pressing block 607 form a fixed structure through the connecting rod 605.

[0042] Through the above technical solution, when the moving plate 604 moves downward, it can synchronously drive the connecting rod 605 to move downward, and one end of the connecting rod 605 passes through the fixed plate 606 for sliding, so as to balance the lower pressing block 607 below and enable the lower pressing block 607 to generate a downward pressing force.

[0043] Working principle: When using this geotextile tensile strength testing device, first, manually pass one end of the geotextile through the hole opened in the rotating roller 303, rotate the adjusting plate 305 to open it, so that the geotextile can completely pass through the rotating roller 303, and then use the resilience of the spring 306 to initially clamp and fix the geotextile. Then start the first motor 302, and the first motor 302 drives the rotating roller 303 to rotate to partially wind and tension the geotextile. Then rotate the threaded rod 307 to drive the lower pressing plate 308 to move downward and press the wound part of the geotextile on the rotating roller 303. The other end of the geotextile is fixed in the same way. After the geotextile is fixed, start the moving mechanism 4 to drive one end of the geotextile to move in the opposite direction for tensile strength testing. The data obtained from the testing is displayed on the display body 5. When it is necessary to detect the upper and lower pressures of the geotextile, start the second motor 602. By driving the lead screw 603 to rotate through the second motor 602, the moving plate 604 can be lifted and lowered. One end of the connecting rod 605 is fixedly connected to the moving plate 604, and the other end passes through the fixed plate 606 and is connected to the lower pressing block 607. In this way, when the moving plate 604 is lifted and lowered, it synchronously drives the lower pressing block 607 to lift and lower, so as to detect the upper and lower tensile strengths of the geotextile, and this completes all the work. The content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit. The scope is defined by the appended claims and their equivalents.
