Description

Technical Field

[0001] The present invention belongs to the technical field of geotextile detection, and specifically relates to a geotextile strength detection device. Background Art

[0002] Geotextiles, also known as geotextiles, are water-permeable geosynthetic materials made of synthetic fibers by needling or weaving.

[0003] Currently, when detecting the strength of geotextiles, it is mostly necessary to use a stretching instrument to stretch the geotextile in a straight line direction. Specifically, two clamping mechanisms in the stretching instrument are used to clamp both ends of the geotextile to be detected respectively, and then the driving mechanism is used to drive the two clamping mechanisms to move away from each other, thereby applying a tensile force to the geotextile. However, since the length of the geotextile is usually long after production, mostly dozens or hundreds of meters, therefore, the existing clamping mechanisms obviously cannot smoothly clamp both ends of the long geotextile, and can only clamp and detect the geotextile in sections. However, after each section of the geotextile is detected, it is necessary to manually adjust the geotextile so that the clamping mechanism clamps at different positions of the geotextile, resulting in a relatively low detection efficiency of the geotextile. Summary of the Invention

[0004] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the embodiments of the present invention is to provide a geotextile strength detection device.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

Subsequently, the driving assembly drives the winding assembly to rotate around the unwinding assembly. When the winding assembly rotates, it can enter the inner area of the first arc-shaped plate from one end of the first arc-shaped plate and can exit from the other end of the first arc-shaped plate. When the winding assembly exits from the other end of the first arc-shaped plate, the force-applying assembly applies a thrust force in the direction away from the unwinding assembly to the winding assembly. When the winding assembly is stressed, the part of the geotextile between the winding assembly and the unwinding assembly can be tensioned, so as to perform a tensile test on this part of the geotextile. After the test on this part of the geotextile is completed, the winding assembly enters the inner side of the first arc-shaped plate from one end of the first arc-shaped plate. At this time, the winding assembly winds up this part of the geotextile, and at the same time, the unwinding assembly unwinds the subsequent geotextile until the winding assembly exits from the other end of the first arc-shaped plate again. This part of the geotextile is completely wound around the winding assembly, and the unwinding assembly unwinds the subsequent geotextile at the position between the winding assembly. The force-applying assembly applies a thrust force in the direction away from the unwinding assembly to the winding assembly again, so that the subsequent part of the geotextile is tensioned again. Subsequently, the winding assembly enters the inner side of the first arc-shaped plate from one end of the first arc-shaped plate again, and the winding assembly winds up this subsequent distributed geotextile again. By repeating this cycle, a segmented automatic tensile test of a long geotextile can be realized. Compared with the prior art, a segmented automatic tensile test of a long geotextile can be performed, which has the advantages of good geotextile strength detection effect and high detection efficiency.

Specific embodiments

[0039] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0040] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.

[0042] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "connected", "set" should be understood in a broad sense. For example, it can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0043] Please refer to Figure 1 and Figure 2, this embodiment provides a geotextile strength detection device, including a bracket 10, a driving component 20, a unwinding component 30, a winding component 40, a force application component 50 and a first arc-shaped plate 60. The first arc-shaped plate 60 is fixedly installed on the inner wall of the bracket 10. The unwinding component 30 and the winding component 40 are arranged inside the bracket 10. The driving component 20 is installed on the inner wall of the bracket 10 and is used to drive the winding component 40 to rotate around the unwinding component 30. The force application component 50 is arranged on the side of the winding component 40. When the winding component 40 rotates to the outer area of the first arc-shaped plate 60, the force application component 50 is used to apply a thrust force to the winding component 40 in the direction away from the unwinding component 30. When the winding component 40 rotates to the inner area of the first arc-shaped plate 60, the winding component 40 winds the geotextile, and at the same time, the unwinding component 30 unwinds the geotextile.

[0044] When it is necessary to detect the tensile strength of the geotextile, one end of the geotextile to be detected can be connected to the winding component 40, and the other end of the geotextile can be wound around the unwinding component 30. Then, the driving component 20 drives the winding component 40 to rotate around the unwinding component 30. When the winding component 40 rotates, it can enter the inner area of the first arc-shaped plate 60 from one end of the first arc-shaped plate 60 and can turn out from the other end of the first arc-shaped plate 60. When the winding component 40 turns out from the other end of the first arc-shaped plate 60, the force application component 50 applies a thrust force to the winding component 40 in the direction away from the unwinding component 30. When the winding component 40 is stressed, the part of the geotextile between the winding component 40 and the unwinding component 30 can be stretched, so as to conduct a tensile test on this part of the geotextile. After the test of this part of the geotextile is completed, the winding component 40 enters the inner area of the first arc-shaped plate 60 from one end of the first arc-shaped plate 60. At this time, the winding component 40 winds this part of the geotextile, and at the same time, the unwinding component 30 unwinds the subsequent geotextile until the winding component 40 turns out from the other end of the first arc-shaped plate 60 again. This part of the geotextile is completely wound on the winding component 40, and the unwinding component 30 unwinds the subsequent geotextile at the position between the winding component 40. The force application component 50 applies a thrust force to the winding component 40 in the direction away from the unwinding component 30 again, so that the subsequent part of the geotextile is stretched again. Then, the winding component 40 enters the inner area of the first arc-shaped plate 60 from one end of the first arc-shaped plate 60 again, and the winding component 40 winds this subsequent distributed geotextile again. By repeating this cycle, a segmented automatic tensile test of a long geotextile can be realized.

[0045] Please refer to Figure 3 , Figure 4 and Figure 7, in one embodiment, the driving assembly 20 includes a motor 201, a driving shaft 202, and a support plate 203. The motor 201 is fixedly installed on the inner wall of the bracket 10. The driving shaft 202 is installed at the output end of the motor 201. There are two groups of the support plates 203, and the two groups of the support plates 203 are fixedly arranged outside the driving shaft 202. The two groups of the support plates 203 are spaced apart along the length direction of the driving shaft 202. The unwinding assembly 30 includes an unwinding roller 301. The unwinding roller 301 is located between the two groups of the support plates 203 and is rotatably arranged outside the driving shaft 202. The winding assembly 40 includes a winding roller 403. The winding roller 403 is rotatably arranged between the two groups of the support plates 203.

[0046] When it is necessary to perform a tensile strength test on the geotextile, one end of the geotextile to be tested can be connected to the winding roller 403, and the other end of the geotextile can be wound around the outside of the unwinding roller 301. Subsequently, the motor 201 drives the driving shaft 202 to rotate, thereby driving the two groups of support plates 203 to rotate. When the two groups of support plates 203 rotate, they drive the winding roller 403 to perform a circular motion. At this time, the winding roller 403 rotates around the unwinding roller 301. When the winding roller 403 rotates out from the other end of the first arc-shaped plate 60, the force-applying assembly 50 applies a thrust away from the unwinding roller 301 to the winding roller 403, so that the part of the geotextile between the winding roller 403 and the unwinding roller 301 is subjected to tension, realizing the tensile test of this part of the geotextile. When the winding roller 403 rotates into the inner side of the first arc-shaped plate 60 from one end of the first arc-shaped plate 60, the winding roller 403 rotates to wind this part of the geotextile, and at the same time, the unwinding roller 301 rotates to unwind the subsequent geotextile to the space between the unwinding roller 301 and the winding roller 403.

[0047] Please refer to Figure 1 、 Figure 3And 5, in one embodiment, two sets of second arc-shaped plates 70 are further fixedly arranged inside the bracket 10. The two sets of second arc-shaped plates 70 are distributed oppositely. A second arc-shaped rack 701 is arranged on the side wall of one set of the arc-shaped plates 70, and a second arc-shaped rack 702 is arranged on the side wall of the other set of the arc-shaped plates 70. The force application assembly 50 includes a third gear 501, a rotating shaft 502, a first sliding sleeve 503, a first elastic member 504 and a first slider 505. The rotating shaft 502 is rotatably arranged outside the support plate 203. The third gear 501 is fixedly arranged at the end of the rotating shaft 502. The first sliding sleeve 503 and the first slider 505 are slidably sleeved outside the rotating shaft 502. One end of the first elastic member 504 is connected to the first slider 505, and the other end is connected to the first sliding sleeve 503 for providing elastic support to the first sliding sleeve 503. A first threaded section 506 is arranged outside the rotating shaft 502. The first slider 505 is in threaded cooperation with the first threaded section 506. A second notch 206 is formed on the support plate 203. The winding assembly 40 further includes a support shaft 401. One end of the support shaft 401 extends between the two support plates 203, and the other end passes through the second notch 206 and is fixedly connected to the first sliding sleeve 503. The winding roller 403 is rotatably matched with the support shaft 401 through a one-way bearing (not shown in the figure).

[0048] When the motor 201 drives the drive shaft 202 to rotate, and then drives the two support plates 203 to rotate, the two support plates 203 can drive the first gear 501, the rotating shaft 502, the first sliding sleeve 503, the elastic member 504, and the first slider 505 to move synchronously. When the winding roller 403 rotates out from the other end of the first arc-shaped plate 60, the third gear 501 moves between the two second arc-shaped plates 70. At this time, the second arc-shaped rack 701 acts on one side of the third gear 501 and meshes with the third gear 501, thereby driving the rotating shaft 502 to rotate. When the rotating shaft 502 rotates, the first slider 505 is driven to slide along the outside of the rotating shaft 502 through the threaded engagement between the first threaded section 506 and the first slider 505. When the first slider 505 slides, it squeezes the first elastic member 504 and then drives the first sliding sleeve 503 to slide synchronously along the outside of the rotating shaft 502. When the first sliding sleeve 503 slides, it drives the winding roller 403 to move through the support shaft 401, so that the winding roller 403 moves away from the unwinding roller 301, thereby applying a tensile force to the part of the geotextile between the winding roller 403 and the unwinding roller 301, realizing the tensile test of this part of the geotextile. When the third gear 501 rotates away from one side of the second arc-shaped rack 701, the third arc-shaped rack 702 acts on the other side of the third gear 501 and meshes with the third gear 501, thereby driving the rotating shaft 502 to rotate in the reverse direction. When the rotating shaft 502 rotates in the reverse direction, the first slider 505 is driven to slide in the reverse direction along the outside of the rotating shaft 502 through the reverse threaded engagement between the first threaded section 506 and the first slider 505. The first slider 505 pulls the first sliding sleeve 503 through the first elastic member 504, so that the first sliding sleeve 503 slides in the reverse direction along the outside of the rotating shaft 502, thereby driving the support shaft 401 and the winding roller 403 to move in the reverse direction, realizing the reset of the winding roller 403. Until the third gear 501 rotates out from the inside of the two second arc-shaped plates 70, the reset winding roller 403 rotates into the inside of the second arc-shaped plate 60 from one end of the second arc-shaped plate 60; when the first slider 505 drives the first sliding sleeve 503 to slide along the outside of the rotating shaft 502 through the first elastic member 504 and then drives the winding roller 403 to move away from the unwinding roller 301, since the winding roller 403 and the support shaft 401 are rotationally connected through a one-way bearing, the winding roller 403 is stressed and thus cannot rotate relative to the support shaft 401, that is, the winding roller 403 cannot unwind the wound geotextile, so that the part of the geotextile between the winding roller 403 and the unwinding roller 301 can be stably tensioned.

[0049] Please refer to Figure 3 In one embodiment, a first arc-shaped rack 601 is fixedly arranged on the side wall of the first arc-shaped plate 60, and a second gear 402 capable of meshing with the first arc-shaped rack 601 is fixedly arranged at the end of the winding roller 403.

[0050] When the winding roller 403 rotates from one end of the second arc-shaped plate 60 into the inner side of the second arc-shaped plate 60, through the meshing action of the second gear 402 and the first arc-shaped rack 601, the second gear 402 can drive the winding roller 403 to rotate relative to the support shaft 401, and then wind the geotextile.

[0051] When the winding roller 403 moves away from the unwinding roller 301, and the part of the geotextile between the winding roller 403 and the unwinding roller 301 is tensioned. Since the unwinding roller 301 is rotatably arranged outside the driving shaft 202, the unwinding roller 301 is likely to rotate as the winding roller 403 moves away, resulting in the part of the geotextile between the winding roller 403 and the unwinding roller 301 not being effectively stretched. To avoid this phenomenon, in one embodiment, a limiting component is further provided on the support plate 203. When the winding roller 403 moves away from the unwinding roller 301, the limiting component is used to limit the rotation between the unwinding roller 301 and the driving shaft 202 to an immovable state, so that the part of the geotextile between the winding roller 403 and the unwinding roller 301 can be stably stretched, thereby improving the tensile test effect of the geotextile.

[0052] Please refer to Figure 4 and Figure 6 , in one embodiment, a first notch 204 is further provided on the support plate 203, a second threaded section 507 is further provided outside the rotating shaft 502, a first gear 302 is fixedly arranged at the end of the unwinding roller 301, and the limiting component includes a second slider 508, a second elastic member 509, a second sliding sleeve 510, a sliding rod 511 and a limiting tooth 512. The second slider 508 and the second sliding sleeve 510 are slidably sleeved outside the rotating shaft 502. The second slider 508 is in threaded cooperation with the second threaded section 507. One end of the second elastic member 509 is connected to the second slider 508, and the other end is connected to the second sliding sleeve 510 for elastically supporting the second sliding sleeve 510. One end of the sliding rod 511 is fixedly connected to the second sliding sleeve 510, and the other end extends from the first notch 204 to one side of the first gear 302 and is connected to the limiting tooth 512.

[0053] When the second arc-shaped rack 701 is meshed with the third gear 503 and thus drives the rotating shaft 502 to rotate, the second slider 508 can slide along the outside of the rotating shaft 502 through the threaded cooperation of the second slider 508 and the second threaded section 507, thereby squeezing the second elastic member 509 to drive the second sliding sleeve 510 to synchronously slide along the outside of the rotating shaft 502. When the second sliding sleeve 510 slides, it drives the sliding rod 511 to move, and the sliding rod 511 drives the limiting tooth 512 to move. The limiting tooth 512 is inserted between two adjacent groups of teeth of the first gear 302 to limit the rotation of the first gear 302 and the unwinding roller 301, so that when the winding roller 403 is away from the unwinding roller 301, the unwinding roller 301 will not rotate compared to the driving shaft 202, and thus will not unwind the geotextile, so that the winding roller 403 and the unwinding roller 301 are not rotated. Part of the geotextile is stably stretched; when the third arc-shaped rack 702 is meshed with the third gear 501 and thus drives the rotating shaft 502 to rotate in the opposite direction, the second slider 508 slides in the opposite direction along the outside of the rotating shaft 502 through the reverse thread cooperation of the second slider 508 and the second threaded segment 507, and then drives the second sleeve 510 to slide in the opposite direction synchronously through the second elastic member 509, and the second sleeve 510 drives the slide rod 511 and the limiting tooth 512 to move in the opposite direction, and the limiting tooth 512 is removed from between two adjacent groups of teeth of the first gear 302 to release the rotation restriction of the unwinding roller 301, so that when the winding roller 403 rotates into the inner side of the first arc-shaped plate 60 and meshes with the first arc-shaped rack 601 to wind up the geotextile, the unwinding roller 301 can respond to the winding action of the geotextile and then unwind the subsequent geotextile.

[0054] See also Figure 3 as well as Figure 4 In one embodiment, two sets of slide rails 205 are fixedly provided on the side wall of the support plate 203, and the first slider 505 and the second slider 508 are respectively slidably matched with one set of the slide rails 205, so that when the rotating shaft 502 rotates, the first slider 505 and the second slider 508 can smoothly slide along the outside of the rotating shaft 502.

[0055] In one embodiment, the first elastic member 504 and the second elastic member 509 may be springs or metal springs, which are not limited herein.

[0056] See also Figure 1 as well as Figure 2 In one embodiment, the bracket 10 is a rectangular frame structure, and a plurality of legs are fixedly provided at the bottom of the bracket 10.

[0057] In the embodiment of the present invention, when it is necessary to detect the tensile strength of the geotextile, one end of the geotextile to be detected can be connected to the winding assembly 40, and the other end of the geotextile is wound around the unwinding assembly 30. Subsequently, the driving assembly 20 drives the winding assembly 40 to rotate around the unwinding assembly 30. When the winding assembly 40 rotates, it can enter the inner area of the first arc-shaped plate 60 from one end of the first arc-shaped plate 60, and can exit from the other end of the first arc-shaped plate 60. When the winding assembly 40 exits from the other end of the first arc-shaped plate 60, the force-applying assembly 50 applies a thrust to the winding assembly 40 in the direction away from the unwinding assembly 30. When the winding assembly 40 is stressed, the part of the geotextile between the winding assembly 40 and the unwinding assembly 30 can be tensioned, so as to conduct a tensile test on this part of the geotextile. When the test on this part of the geotextile is completed, the winding assembly 40 enters the inner side of the first arc-shaped plate 60 from one end of the first arc-shaped plate 60. At this time, the winding assembly 40 winds this part of the geotextile, and at the same time, the unwinding assembly 30 unwinds the subsequent geotextile until the winding assembly 40 exits from the other end of the first arc-shaped plate 60 again. This part of the geotextile is completely wound on the winding assembly 40, and the unwinding assembly 30 unwinds the subsequent geotextile at the position between the winding assembly 40. The force-applying assembly 50 applies a thrust to the winding assembly 40 in the direction away from the unwinding assembly 30 again, so that the subsequent part of the geotextile is tensioned again. Subsequently, the winding assembly 40 enters the inner side of the first arc-shaped plate 60 from one end of the first arc-shaped plate 60 again, and the winding assembly 40 winds this subsequent distributed geotextile again.
