Description

Technical Field

[0001] The present invention relates to the technical field of artificial turf detection, and specifically to a device and method for detecting the tensile resistance of artificial turf. Background Art

[0002] Artificial turf is an artificially manufactured simulated turf, usually made of synthetic fibers (such as polyethylene, polypropylene), which simulates the appearance and feel of natural turf. By providing an aesthetic, practical and economical solution, it meets people's different requirements for lawn decoration and functional needs. It is widely used in sports stadiums, landscape design, residential gardening and other fields to replace natural turf or improve the environmental landscape. During the manufacturing process of artificial turf, various quality and performance tests need to be carried out on it. The tensile resistance test is one of the more important items, because it directly affects the service life, safety and performance of artificial turf. Therefore, detecting the tensile resistance of artificial turf helps to ensure its safety, durability, environmental adaptability and performance, and is an important means to guarantee product quality and user experience.

[0003] In the existing Chinese patent with the publication number CN211602704U and the name of "artificial turf tensile resistance detection device", it includes a workbench. When the hydraulic tank fixedly installed on the upper end wall of the workbench is started, the hydraulic tank will transport the hydraulic pressure of the internal machine to the moving block through the hydraulic pipe. The moving block can drive the hydraulic upper clamp and the hydraulic lower clamp to move left and right through the hydraulic column, and the hydraulic upper clamp and the hydraulic lower clamp can perform up and down clamping movements under the action of hydraulic pressure to clamp the turf. So when the two sets of hydraulic upper clamps and hydraulic lower clamps clamp the two ends of the turf, the moving block can drive the hydraulic upper clamp and the hydraulic lower clamp to move through the hydraulic pressure, and stretch and tighten the turf clamped by the hydraulic upper clamp and the hydraulic lower clamp. In this way, when the tensile force detection device tests the tensile force of the turf, the turf itself does not have elasticity, and the tensile force data detected by the tensile force detection device is more accurate and perfect.

[0004] However, in the above technology, the artificial grass on the artificial turf is clamped by two tensile clamps, and then stretched and detected. The two tensile clamps can only detect one test point on the artificial turf. During the tensile resistance test, there is more than one test point on the artificial turf. When using the above device, after the detection of one point is completed, the position of the artificial turf needs to be adjusted, and then the next test point is tested. Repeated adjustment operations are required, and the artificial turf needs to be loaded and unloaded when the device stops, resulting in a reduction in the test efficiency. Therefore, we have proposed a device and method for detecting the tensile resistance of artificial turf to solve the above problems. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a device and method for detecting the tensile resistance of artificial turf, which solves the problem that only one test point on the artificial turf can be detected.

[0015] A method for detecting the tensile resistance of artificial turf, comprising the following steps: S1.

Place the artificial turf on the loading table, and place the artificial turf on the loading table in a group of second clamping members on the loading table to stably clamp it; S2.

The artificial turf installed in step S1 moves to the installation box to complete loading.

According to the points to be tested, control the mechanical claws at the corresponding points to clamp the artificial grass on the artificial turf. The first hydraulic rod drives the mechanical claws to move upward for a tensile test. The tensile sensor monitors the tensile force in real time and displays the detection data on the control device; S221. The third gear rotates as the second gear rotates. During the meshing process of the second gear and the first gear, the third gear is not connected to the fourth gear. When the second gear and the first gear just separate, the motor continues to operate, the third gear rotates, meshes with the fourth gear, drives the fourth gear to rotate 180 degrees, and drives the rotating block and the two lever arms to rotate 180 degrees through the connecting member, so that the lever arms rotate to dial down the artificial turf that has undergone a tensile test located on the unloading box, and the artificial turf falls into the unloading box to complete unloading. When the two lever arms are parallel to the ground, the motor stops operating; S222. Take out the artificial turf that has undergone a tensile test in the unloading box for processing.

[0016] The present invention has the following beneficial effects: (1). In the artificial turf tensile resistance detection device and method, through the combined use of the provided tensile sensor, mounting plate, and multiple mechanical claws at the bottom thereof, the device can perform tensile tests on multiple points on the artificial turf at one time, avoiding the need for repeated adjustment operations. Moreover, through the combined use of the provided rotating frame, second clamping member, driving member, rotating block, and lever arm, when performing a tensile test on the artificial turf on the installation box, it is used for loading and unloading the artificial turf on the other two second clamping members. Thus, when the tensile test of the artificial turf on the installation box ends, a new artificial turf can be quickly put in place without long-term waiting, improving the efficiency of the tensile test.

[0017] (2) The artificial turf tensile resistance detection device and method, through the combined use of the upper pressing plate, lower pressing plate, sleeve plate, sliding plate, connecting spring, connecting lock, and the third hydraulic rod, can be applicable to artificial turfs of multiple different areas, and the device has a large application range.

The connecting lock 14 is mounted at the other end of the third hydraulic rod 13 for fixing the position of the feeding device; The feeding device includes a rotating frame 37, second clamping members arranged in a circumferential array, and a driving member connected to the discharging device. The rotating frame 37 includes a circular plate and brackets arranged in a circumferential array along its outer circumference. There are three brackets. There are three groups of second clamping members. The second clamping members are arranged at the ends of the brackets away from the circular plate. The driving member is arranged at the bottom of the circular plate. When the driving member operates, the rotating frame 37 rotates to move the artificial turf that has not been subjected to a tensile test onto the mounting member and move the artificial turf that has been subjected to a tensile test onto the discharging box 35; The discharging device includes a rotating block 32, toggle rods 33 symmetrically arranged on the rotating block 32, and a discharging box 35. The rotating block 32 is arranged on the driving member. The toggle rods 33 are arranged on the outer peripheral wall of the rotating block 32. The rotating block 32 and the toggle rods 33 are suspended above the discharging box 35.

[0025] Specifically, the mechanical clamping jaw 6 includes two symmetrical clamping blocks, a first electric telescopic rod arranged outside the clamping blocks, and a mounting block. The first electric telescopic rod is rotatably mounted between the outside of the clamping blocks and the mounting block and is electrically connected to the control device 7. The mounting block is mounted at the bottom of the mounting plate 5. When the first electric telescopic rod operates, the two clamping blocks clamp the artificial grass.

[0026] In this implementation scheme, the first hydraulic rod 3 drives the mounting plate 5 and the mechanical gripper 6 to move downward. According to the points to be tested, the first electric telescopic rod at the corresponding point controls the movement of the clamping block so that the clamping block clamps the artificial grass on the artificial turf. Then the first hydraulic rod 3 drives the mechanical gripper 6 to move upward for a tensile test (i.e., the detection of the tensile resistance ability). The tensile sensor 4 monitors the tensile force in real time and displays the detection data on the control device 7.

[0027] Specifically, the moving part includes a fixed plate 11 and a second hydraulic rod 9 installed at its bottom. A fixed frame 12 is installed on the fixed plate 11, and the fixed frame 12 is in the shape of an L placed horizontally. Guide rods 10 are symmetrically arranged at the bottom of the fixed plate 11. The second hydraulic rod 9 and the guide rods 10 are both installed in the installation box 1, and the fixed plate 11 is arranged in the installation box 1. A connecting groove 23 is penetrated and connected to the fixed frame 12, and the connecting groove 23 is opened at the top of the installation box 1. The connecting lock 14 includes a lock body, a lock block and a second electric telescopic rod. The lock body is clamped at one end of the second clamping part arranged above the installation box 1. The second electric telescopic rod is installed on the side of the lock body away from the third hydraulic rod 13 and is connected to the lock block. The second electric telescopic rod is electrically connected to the control device 7, and the lock block is used to limit the second clamping part arranged above the installation box 1.

[0028] In this implementation scheme, when the artificial turf without a tensile test moves to the installation box 1 along with the second clamping part outside it, the second hydraulic rod 9 drives the fixed frame 12, the third hydraulic rod 13 and the connecting lock 14 to move upward through the fixed plate 11. The connecting lock 14 is clamped outside the convex blocks 18 at the same end of the upper pressing plate 15 and the lower pressing plate 16 on the same side. The second electric telescopic rod drives the lock block to be clamped above the upper convex block 18 to limit the two convex blocks 18, completing the limit fixation of the second clamping part. Then the tensile test can be carried out.

[0029] Specifically, the second clamping member includes two symmetrically arranged upper pressing plates 15 and a lower pressing plate 16 disposed below the upper pressing plate 15. The upper pressing plate 15 is linearly arrayed with cylinders 17, and the lower ends of the cylinders 17 are connected to the lower pressing plate 16 by screws. One side of the upper pressing plate 15 is installed at one end of the bracket; convex blocks 18 are respectively provided at both ends of the upper pressing plate 15 and both ends of the lower pressing plate 16. Two convex blocks 18 at the same end in the second clamping member on the mounting box 1 are clamped between the lock body and the lock block of the connecting lock 14; a sleeve plate 19 is installed at the inner end of one side of the lower pressing plate 16, and a sliding plate 20 is installed at the inner end of the other side of the lower pressing plate 16. The other end of the sliding plate 20 extends into the sleeve plate 19, and a connecting spring 21 is installed between the end of the sliding plate 20 and the inner wall of the sleeve plate 19. Convex strips are respectively provided on the relatively close sides of the upper pressing plate 15 and the lower pressing plate 16. Guide blocks 22 are linearly arrayed on the outer side of the lower pressing plate 16, and the guide blocks 22 are connected to the guide grooves, and the guide grooves are opened on the outer side wall of the upper pressing plate 15; a loading table 36 is provided on one side of the mounting box 1, and the mounting box 1, the unloading box 35 and the loading table 36 are annularly arranged below the rotating frame 37.

[0030] In this embodiment, one side of the artificial turf is placed between the upper pressing plate 15 and the lower pressing plate 16 on one side. The cylinder 17 on this side drives the lower pressing plate 16 to move upward. The guide block 22 moves in the guide groove, and the convex strips between the upper pressing plate 15 and the lower pressing plate 16 clamp the artificial turf. The cylinder 17 stops operating, and the other side repeats the operation to clamp the artificial turf.

[0031] After the connecting lock 14 is connected to the convex block 18, the third hydraulic rod 13 operates to pull the upper pressing plate 15. The upper pressing plates 15 on both sides move to both sides respectively. The sliding plate 20 moves in the sleeve plate 19, and the connecting spring 21 is stretched until the artificial turf is completely flattened. The third hydraulic rod 13 stops operating, and then the tensile test can be carried out.

[0032] Specifically, a base 34 is installed at the bottom of the driving member. The base 34 is placed on the ground. The driving member includes a first gear 24, a second gear 25, a third gear 26, a fourth gear 28, a motor 27 and a connecting member. The first gear 24 is arranged below the circular plate in the rotating frame 37 and is coaxially arranged with the circular plate. The second gear 25 is meshed and arranged on one side of the first gear 24. The third gear 26 is arranged below the second gear 25 and is coaxially arranged with the second gear 25. The second gear 25 and the third gear 26 are arranged on the base 34. The fourth gear 28 is arranged on the side of the third gear 26 away from the first gear 24 and is meshed and connected with the third gear 26. The motor 27 is arranged below the third gear 26 and is installed on the base 34 by screws. The motor 27 is electrically connected to the control device 7. The connecting member is arranged above the fourth gear 28. The first gear 24, the second gear 25, the third gear 26 and the fourth gear 28 are all spur gears. The second gear 25 is a sector gear of 120 degrees, and the third gear 26 is a half gear. The second gear 25 and the third gear 26 are arranged on the same side. The connecting member includes two symmetrically arranged rotating wheels 29 and a belt 30 sleeved outside thereof. One rotating wheel 29 is installed above the fourth gear 28 and is coaxially arranged with the fourth gear 28. Two meshed fifth gears 31 are installed above the other rotating wheel 29. The fifth gears 31 are bevel gears. One fifth gear 31 is installed on the rotating wheel 29, and the other fifth gear 31 is connected to the rotating block 32.

[0033] In this implementation scheme, the motor 27 drives the second gear 25 and the third gear 26 to rotate, so that the second gear 25 is first meshed and connected with the first gear 24, causing the rotating frame 37 to rotate, so that the three groups of second clamping members carry the artificial turf installed thereon to change positions. When the second gear 25 is disengaged from the first gear 24, the third gear 26 is meshed and connected with the fourth gear 28, causing the two rotating wheels 29 to rotate, thereby driving the two fifth gears 31 to rotate, which is used to drive the rotating block 32 and the two lever rods 33 installed thereon to rotate, so that the lever rods 33 rotate, and the artificial turf that is released from the extrusion limit on the blanking box 35 is pushed down and falls into the blanking box 35 for collection.

[0034] A method for detecting the tensile resistance of artificial turf, comprising the following steps: S1. According to the area of the artificial turf, control the third hydraulic rod 13 to drive the connecting lock 14 to move and match the position of the convex block 18. Place the artificial turf on the feeding table 36, and place the artificial turf on the feeding table 36 in a set of second clamping members to stably clamp it; S2. The motor 27 operates to make the second gear 25 and the third gear 26 rotate. The second gear 25 is meshed and connected with the first gear 24, so that the first gear 24 and the rotating frame 37 rotate 120 degrees. The artificial turf installed in step S1 moves to the installation box 1 to complete feeding. At this time, the second clamping member originally located on the blanking box 35 moves to the feeding table 36 to continue feeding, and the artificial turf that has undergone a tensile test and its connected second clamping member originally located on the installation box 1 move to the blanking box 35 for blanking; S211. The second clamping member equipped with the artificial turf that has not undergone a tensile test moves to the installation box 1, and the moving member drives the four fixing frames 12 and the structures provided thereon to move upward, so that the connecting lock 14 is clamped to the second clamping member to limit and fix the second clamping member; S212. The first hydraulic rod 3 drives the mounting plate 5 and the mechanical claw 6 to move downward. According to the points to be tested, control the mechanical claw 6 at the corresponding point to clamp the artificial grass on the artificial turf. The first hydraulic rod 3 drives the mechanical claw 6 to move upward for a tensile test. The tensile sensor 4 monitors the tensile force in real time and displays the detection data on the control device 7; S221. The third gear 26 rotates as the second gear 25 rotates. During the meshing process of the second gear 25 and the first gear 24, the third gear 26 is not connected to the fourth gear 28. When the second gear 25 and the first gear 24 are just separated, the motor 27 continues to operate, the third gear 26 rotates, meshes with the fourth gear 28, and drives the fourth gear 28 to rotate 180 degrees. Through the connecting member, the rotating block 32 and the two lever rods 33 are rotated 180 degrees, so that the lever rods 33 rotate to dial down the artificial turf that has undergone a tensile test located on the blanking box 35, and the artificial turf falls into the blanking box 35 to complete blanking. When the two lever rods 33 are parallel to the ground, the motor 27 stops operating; S222. Take out the artificial turf that has undergone a tensile test in the blanking box 35 for processing.

[0035] During use, the artificial turf is placed on the loading table 36. The artificial turf on the loading table 36 is placed between the upper pressing plate 15 and the lower pressing plate 16 on one side of the second clamping member on the loading table 36. The air cylinder 17 on this side drives the lower pressing plate 16 to move upward. The guiding block 22 moves in the guiding groove, and the rib between the upper pressing plate 15 and the lower pressing plate 16 clamps the artificial turf. The air cylinder 17 stops operating, and the operation is repeated on the other side to clamp the artificial turf. The fixing frame 12, the third hydraulic rod 13, and the connecting lock 14 on the installation box 1 move downward into the installation box 1 to release the limit on the second clamping member thereon. Then, the motor 27 drives the second gear 25 and the third gear 26 to rotate, so that the second gear 25 first meshes and connects with the first gear 24, causing the rotating frame 37 to rotate, and causing the three groups of second clamping members to carry the artificial turf installed thereon to change positions. The artificial turf that has not been subjected to the tensile test on the original loading table 36 moves to the installation box 1, the artificial turf that has been subjected to the tensile test on the original installation box 1 moves to the blanking box 35, the artificial turf on the original blanking box 35 has been blanked, and the second clamping member that does not clamp the artificial turf moves to the loading table 36 to continue loading. After the artificial turf moves to the installation box 1, the second hydraulic rod 9 drives the fixing frame 12, the third hydraulic rod 13, and the connecting lock 14 to move upward through the fixing plate 11. The connecting lock 14 is stuck outside the convex block 18 at the same end of the upper pressing plate 15 and the lower pressing plate 16 on the same side. The second electric telescopic rod drives the lock block to be stuck above the upper convex block 18 to limit the two convex blocks 18, completing the limit fixation of the second clamping member. Subsequently, the first hydraulic rod 3 drives the mounting plate 5 and the mechanical claw 6 to move downward. According to the points to be tested, the first electric telescopic rod at the corresponding point controls the clamping block to move, so that the clamping block clamps the artificial grass on the artificial turf. The first hydraulic rod 3 drives the mechanical claw 6 to move upward to conduct a tensile test. The tensile sensor 4 monitors the tensile force in real time and displays the detection data on the control device 7.

[0036] During the tensile test, the air cylinders 17 on both sides of the artificial turf that has moved to the blanking box 35 drive the lower pressing plate 16 to move downward to release the clamping of the artificial turf. When the second gear 25 disengages from the first gear 24, the third gear 26 meshes with the fourth gear 28, causing the two rotating wheels 29 to rotate, thereby driving the two fifth gears 31 to rotate, which is used to drive the rotating block 32 and the two dial rods 33 mounted thereon to rotate, so that the dial rods 33 rotate to push down the artificial turf on the blanking box 35 that has been released from the extrusion limit and fall into the blanking box 35 for collection. During this process, the second clamping member that has moved to the loading table 36 continues to be loaded.

[0037] In summary, through the stretching detection device, the control device 7, the limiting device, the feeding device and the discharging device, the present application can perform tensile tests on multiple points on the artificial turf at one time, avoiding the need for repeated adjustment operations. Moreover, when the tensile test on the artificial turf on the installation box 1 is completed, a new artificial turf can be quickly put in place without long-term waiting, improving the efficiency of the tensile test. The device has a wide range of applications, can automatically discharge materials, avoiding the need for manual operation, and facilitating the centralized collection and treatment of the tested artificial turf.
