Description

Technical Field

[0001] The present invention relates to the technical field of tensile testing of new material geotextiles, and more specifically, to a tensile test device for new material geotextiles used in water conservancy construction. Background Art

[0002] The geotextile tensile test is a device for the strength testing of geotextiles, used for the tensile performance testing of geosynthetics in industries such as transportation, water conservancy, tunnels, and construction projects, including geotextiles, composite geotextiles, geogrids, geomembranes, and related products. Currently, geotextiles are continuously being developed with new materials to increase their tensile strength and adaptability, and thus it is necessary to conduct tensile tests on different new material geotextiles. During the process of conducting a tensile test on geotextiles used in water conservancy construction, it is usually necessary to clamp and fix the geotextiles. Most of the existing methods for fixing geotextiles in geotextile tensile test devices are two-point clamping and drum winding. The two-point clamping method only fixes the specimen through two points, and the clamping area is small, which easily causes local wrinkles or sliding on the geotextile during the stress process. In addition, during the test process of the drum winding method, the problem of uneven winding usually occurs. In this way, when the geotextile is subjected to a tensile test, the stress will concentrate on the wrinkled or uneven parts, resulting in excessive local stress and smaller stress in other parts. This will cause the test results to not truly reflect the overall performance of the geotextile.

[0003] To solve the above problems, a tensile test device for new material geotextiles used in water conservancy construction is proposed. Summary of the Invention

[0018] Refer to FIGS. 1 to Figure 10As shown in the figure, this is an embodiment of the present invention. A new material geotextile tensile test device for water conservancy construction provided will be elaborated in detail below: It includes a test platform 1. On one side of the test platform 1, a test cylinder 2 is rotatably connected. On the side of the test platform 1 far from the test cylinder 2, a winding drum 3 is rotatably connected. At the bottom end of the test cylinder 2, a servo motor one 4 is fixedly connected. On the test platform 1, a sliding groove 5 is opened at the position of the winding drum 3. Inside the sliding groove 5, a threaded rod 6 is rotatably connected. A sliding block 7 is threadedly connected to the outer surface of the threaded rod 6. At the end of the threaded rod 6, a servo motor two 8 is fixedly connected. A flattening component is arranged on the test platform 1; The flattening component includes two arc-shaped grooves 91 opened on the top and the tabletop of the test platform 1 in the direction close to the test cylinder 2. Inside the arc-shaped groove 91 on the tabletop, a movable ball 92 is movably connected. Between the movable ball 92 and the inner wall of the arc-shaped groove 91 on the tabletop, an arc-shaped spring 93 is arranged. At the top of the movable ball 92, a connecting rod 94 is fixedly connected. At the top end of the connecting rod 94, a flattening roller 95 is fixedly connected. At the top of the flattening roller 95, a limiting rod 96 is fixedly connected.

[0019] Furthermore, the servo motor one 4 is installed inside the test platform 1. The connecting rod 94 is slidably connected to the arc-shaped groove 91 on the tabletop. The flattening roller 95 is arranged at an oblique side position of the test cylinder 2. The limiting rod 96 is slidably connected between the arc-shaped groove 91 at the top of the test platform 1. The sliding block 7 is slidably connected to the sliding groove 5. The top of the sliding block 7 is rotatably connected to the bottom of the winding drum 3. The servo motor two 8 is fixedly connected outside the test platform 1. The two ends of the arc-shaped spring 93 are respectively fixedly connected to the opposite directions of the movable ball 92 and the arc-shaped groove 91 on the tabletop.

[0020] Furthermore, a locking component is arranged inside the limiting rod 96. The locking component includes a locking groove 101 opened inside the limiting rod 96. Inside the locking groove 101, a locking rod 102 is slidably connected. At the top end of the locking rod 102, a control rod 103 is fixedly connected. A spring one 104 is sleeved on the outer side of the rod body of the control rod 103. The two ends of the spring one 104 are respectively fixedly connected to the opposite ends of the locking rod 102 and the locking groove 101. An arc-shaped insertion hole 105 is opened on the outer surface of the limiting rod 96. At the position corresponding to the arc-shaped insertion hole 105 inside the arc-shaped groove 91 at the top of the test platform 1, an arc-shaped insertion rod 106 is fixedly connected. A fixing hole 107 is opened on the outer surface of the arc-shaped insertion rod 106.

[0021] Furthermore, the control rod 103 is slidably connected to the limiting rod 96. The arc-shaped insertion hole 105 and the arc-shaped insertion rod 106 are matched with each other. The fixing hole 107 and the locking rod 102 are matched with each other.

[0022] Further, a clamping assembly is provided outside the test cylinder 2. The clamping assembly includes two guiding grooves 111 formed at both ends of the test cylinder 2. The two guiding grooves 111 at each end are mirror - image arranged. A concave connecting rod 112 is slidably connected in each guiding groove 111. Two concave connecting rods 112 with the same vertical and horizontal dimensions are fixedly connected to an arc - shaped fixing plate 113. Saw - tooth grooves 114 are formed at opposite ends of the two arc - shaped fixing plates 113. The front section of the guiding groove 111 is arc - shaped. The saw - tooth grooves 114 on the two arc - shaped fixing plates 113 can be combined, and the two saw - tooth grooves 114 can also increase the contact area between the fixture and the geotextile, and there will be no slipping phenomenon during the test.

[0023] Further, a notch 115 is formed on the outer surface of the test cylinder 2. When the two arc - shaped fixing plates 113 are combined, they are matched with the notch 115. The rear section of the guiding groove 111 near the notch 115 is obliquely arranged towards the notch 115. In addition, the section of the notch 115 formed on the outer surface of the test cylinder 2 is inclined. At the same time, the sections of the two arc - shaped fixing plates 113 correspond to the section of the notch 115. In this way, when the arc - shaped fixing plate 113 fills or leaves the notch 115, it will not be restricted by the section of the test cylinder 2 corresponding to the notch 115.

[0024] Further, a driving assembly is provided at the top of the test cylinder 2. The driving assembly includes a rotating rod 121 fixedly connected to the top end of the test cylinder 2. Two rotating disks 122 are rotatably connected to the outer surface of the rotating rod 121. Driving rods 123 are fixedly connected to the outer surfaces of the two rotating disks 122. Contact grooves 124 are formed on the two driving rods 123. A driven groove rod 125 is also fixedly connected to the outer surface of the upper rotating disk 122. A driven rod 126 is slidably connected inside the driven groove rod 125. A toothed plate 127 is fixedly connected to the bottom end of the driven rod 126. A gear 128 is meshed with the side of the toothed plate 127. Multiple teeth 129 are fixedly connected to the outer surface of the lower rotating disk 122. A torsion spring 1211 is provided at the bottom of the lower rotating disk 122.

[0025] Further, the top end of the rotating rod 121 is rotatably connected to the test platform 1. The gear 128 is meshed with the multiple teeth 129 on the outer surface of the lower rotating disk 122. A sliding groove 1210 is formed on the test cylinder 2. The toothed plate 127 is slidably connected to the sliding groove 1210. The gear 128 is rotatably connected to the test platform 1.

[0026] And when the arc - shaped fixing plate 113 is removed from the notch 115, the contact groove 124 of the driving rod 123 pushes the concave connecting rod 112 to rotate in the guiding groove 111, so that the arc - shaped fixing plate 113 slides outward along the arc - shaped section of the guiding groove 111 near the notch 115. The concave connecting rod 112 continues to slide in the guiding groove 111, and the arc - shaped fixing plate 113 can be removed from the notch 115.

[0027] Furthermore, a limiting component is arranged inside the rotating rod 121. The limiting component includes a track groove 131 formed on the outer surface of the rotating rod 121. An embedding groove 132 is formed in the track groove 131. An L-shaped rod 133 is slidably connected in the track groove 131. An L-shaped embedding rod 134 is slidably connected inside the L-shaped rod 133. A second spring 135 is arranged between the L-shaped embedding rod 134 and the L-shaped rod 133. Two ends of the second spring 135 are respectively fixedly connected to opposite ends of the L-shaped rod 133 and the L-shaped embedding rod 134.

[0028] Furthermore, the L-shaped rod 133 is fixedly connected to the upper rotating disc 122.

[0029] Combining the above embodiments, the following is the entire working process and working principle of the above embodiments: The working state is as follows: When tensile testing of geotextiles is required, first pull the geotextile outside the reel 3 to the position of the notch 115 opened on the outer surface of the test cylinder 2. At this time, manually rotate the upper rotating disk 122. Then, the driving rod 123 outside the rotating disk 122 will rotate around the rotating disk 122 as the center. At the same time, the inner wall of the abutting groove 124 opened on the driving rod 123 will abut against the concave connecting rod 112, causing the concave connecting rod 112 to move on the test cylinder 2 along the track of the guiding groove 111. At the same time, the arc-shaped fixing plate 113 connected thereto will slide along the track of the guiding groove 111 towards the notch 115 opened on the test cylinder 2. During the rotation of the upper rotating disk 122, the driven groove rod 125 fixed on its outer surface will move the driven rod 126 and the toothed plate 127 to slide in the chute 1210. During the movement of the toothed plate 127, the gear 128 will rotate. When the gear 128 rotates, it will move the tooth 129 outside the lower rotating disk 122, causing the lower rotating disk 122 to rotate in the opposite direction to the upper rotating disk 122. At this time, the lower rotating disk 122 will drive the driving rod 123 arranged on its outer surface to rotate accordingly. At the same time, the inner wall of the abutting groove 124 on the driving rod 123 will also abut against the concave connecting rod 112 inside it, causing the other arc-shaped fixing plate 113 to move along the track of the guiding groove 111 arranged in a mirror image. In this way, the two arc-shaped fixing plates 113 outside the test cylinder 2 will move relatively to the position of the notch 115. When the concave connecting rod 112 moves to the corner of the guiding groove 111, it will move obliquely towards the notch 115 for a certain distance. At this time, the concave connecting rod 112 will drive the arc-shaped fixing plate 113 to slide into the notch 115 along the inclined cut surface of the guiding groove 111 close to the notch 115. In this way, when the arc-shaped fixing plate 113 is inserted into the notch 115, the test cylinder 2 will become a complete cylinder. During the rotation of the upper rotating disk 122, it will also drive the L-shaped rod 133 to slide in the track groove 131. When the serrated groove 114 arranged at the opposite ends of the two arc-shaped fixing plates 113 clamps the geotextile wound outside the reel 3, since the track groove 131 is shallower than the insertion groove 132 and the track groove 131 is arranged in an arc shape, during the rotation of the upper rotating disk 122, the L-shaped rod 133 can slide in the track groove 131. When the L-shaped rod 133 does not rotate to the position of the insertion groove 132, the L-shaped insertion rod 134 will always be in a state of abutting against the inner wall of the track groove 131, causing the L-shaped insertion rod 134 to move away from the rotating rod 121. At the same time, it will also pull the second spring 135 to deform. In this way, when the end of the L-shaped rod 133 moves to the corresponding position of the insertion groove 132, the second spring 135 will push the L-shaped insertion rod 134 into the insertion groove 132 to achieve locking, thereby realizing the clamping of the geotextile by the test cylinder 2. The anti-slip pattern can significantly increase the friction between the fixture and the clamped object, prevent sliding during use, and thus improve the stability of the fixture.In addition, compared with the previous two-point clamping method, the geotextile is more evenly stressed in the area between the clamping points in this clamping method, so that no wrinkles will appear longitudinally during the test of the geotextile, thereby improving the accuracy of the test results. When unlocking is required, pull the L-shaped insertion rod 134 backward to release the restriction with the rotating rod 121. At this time, the lower rotating disk 122 will reverse under the action of the coil spring 1211. At the same time, while driving the gear 128 to rotate by the teeth 129, the toothed plate 127 is driven to slide. At this time, the upper rotating disk 122 will drive the driven rod 126 to contact the driven groove rod 125 during the sliding of the toothed plate 127, so that the rotating disk 122 will reverse, thus achieving the purpose of resetting.

[0030] After the geotextile is fixed on the above-mentioned test cylinder 2, start the servo motor 1 4 to drive the test cylinder 2 to rotate and wind the geotextile outside the reel 3 onto the test cylinder 2. During the winding of the geotextile, the flattening rod 95 will receive the thrust transmitted from the outer surface of the geotextile. At this time, the flattening rod 95 will drive the connecting rod 94 and the movable ball 92 to squeeze the arc spring 93 in the arc groove 91. In this way, the reaction force of the arc spring 93 will push the movable ball 92 and the connecting rod 94 to slide in the arc groove 91 on the table, and at the same time drive the flattening roller 95 to continuously adjust the winding tension of the geotextile during the winding process, so that the geotextile can be evenly wound outside the test cylinder 2. This can ensure that the geotextile is evenly stressed during the test, making the test data more truly reflect the actual performance of the material. After the winding is completed, manually push the limit rod 96 to move along the trajectory of the arc groove 91 at the top of the test platform 1 towards the direction of the arc spring 93. When the limit rod 96 moves to the position of the arc insertion rod 106, the end of the arc insertion rod 106 will contact the locking rod 102, and the locking rod 102 will drive the control rod 103 to slide upward and squeeze the spring 1 104. When the fixing hole 107 on the outer surface of the arc insertion rod 106 moves to the corresponding position of the locking rod 102, the spring 1 104 will push the locking rod 102 to embed into the fixing hole 107. At this time, the limit rod 96 and the flattening roller 95 will not move under the action of the arc spring 93, and the flattening roller 95 will not contact the geotextile during the detection of the geotextile by the test cylinder 2, avoiding affecting the detection results. When unlocking is required, pull up the control rod 103 to drive the locking rod 102 out of the fixing hole 107 to release the locking between the locking rod 102 and the arc insertion rod 106.

[0031] By rotating the servo motor two 8, the threaded rod 6 is driven to rotate, driving the sliding block 7 and the drum 3 to move along the trajectory of the sliding groove 5 towards the test cylinder 2. At this time, the locking rod 102 is driven to leave the fixing hole 107 by pulling up the control rod 103, releasing the locking between the locking rod 102 and the arc-shaped insertion rod 106, and starting the servo motor one 4 to drive the test cylinder 2 to rotate. The excess geotextile is smoothed by the flattening roller 95 and then wound up. By testing the tensile strength of various parts of the geotextile, the overall performance of the material can be ensured to be uniform, which helps to avoid engineering hazards caused by insufficient local strength.
