Description

Technical Field

[0001] The present invention belongs to the field of fiber braided cable simulation experiments, and particularly relates to a fiber braided cable experimental simulation device and method. Background Art

[0002] In many fields such as ships, machinery, buildings, and aerospace, fiber braided cables have emerged as indispensable structural materials, highly regarded for their light weight, excellent strength, and remarkable corrosion resistance.

[0003] In the design process of fiber braided cables, experimental simulation devices play a crucial role. These devices are specifically used to simulate the mechanical properties and durability performance of fiber braided cables in their usage environments, especially under extreme conditions such as cutting, abrasion, heat, and humidity, covering multiple aspects such as shear strength, abrasion resistance strength, and tensile strength. However, most of the current experimental simulation devices on the market can only simulate and test a single mechanical property under a specific scenario. This means that in order to comprehensively evaluate the various mechanical properties of fiber braided cables, researchers have to prepare multiple different simulation experimental devices, which undoubtedly greatly increases the cost and complexity of the experiments.

[0004] In addition, although there is already an experimental simulation device integrating multiple mechanical property experimental structures, it still has limitations in practical applications. Although this device reduces the number of required experimental equipment, its various experimental modules are independent of each other and cannot operate simultaneously. Therefore, when it is necessary to simulate the mechanical properties of fiber braided cables in complex scenarios, such as first experiencing a certain magnitude of shear force and then bearing a certain degree of abrasion, the existing experimental simulation devices are inadequate. Experimental personnel have to first remove the fiber braided cable from the experimental shear strength module and then install it on the experimental abrasion resistance strength module for testing. This process not only increases the workload of the experimental personnel, but also the force-bearing situation of the fiber braided cable may change during the removal and reinstallation processes, thus affecting the accuracy of the experimental results.

[0032] Please refer to Figures 1-5 , the present invention provides a fiber braided cable experimental simulation device, which includes: a top plate 2, a tensile test module 3, and a shearing and grinding integrated test module 4; the tensile test module 3 and the shearing and grinding integrated test module are arranged on the top plate 2; the tensile test module is used to be connected to both ends of the fiber braided cable 1 for fixing the fiber braided cable 1 and testing the tensile strength of the experimental fiber braided cable 1; the shearing and grinding integrated test module includes a first driving member 41, a first transmission member 42, a first mounting member 43, a first transmission assembly 44, and a grinding wheel 45; the first driving member 41 is arranged on the top surface of the top plate 2, one end of the first transmission member 42 is connected to the first driving member 41, and a first connecting member 421 and a second connecting member 422 are arranged at intervals at the end of the first transmission member 42 far from the first driving member 41; a first through hole is arranged on the top plate 2, a second transmission member 431 is arranged on the first mounting member 43, and the second transmission member 431 passes through the first through hole and is connected to the first connecting member 421 of the first transmission member 42; a first groove 4311 is arranged at the connection end of the second transmission member 431 and the first transmission member 42, and a first spiral groove 4312 is arranged on the inner side wall of the first groove 4311, and the second transmission member 431 is connected to the first connecting member 421 through the first spiral groove 4312;

[0033] The first transmission assembly 44 includes a second mounting member 441 and a third transmission member 442; a second through hole 21 is provided on the top plate 2, one end of the second mounting member 441 passes through the second through hole 21 and is connected to the first mounting member 43, and the other end is rotatably connected to the third transmission member 442; a third through hole 4421 is provided on the third transmission member 442, and the third transmission member 442 is coaxially arranged with the second transmission member 431 and the first transmission member 42 through the third through hole 4421 and is in clearance fit with the first transmission member 42; a second spiral groove 4422 is provided on the inner side wall of the third through hole 4421, and the third transmission member is connected to the second connecting member 422 through the second spiral groove 4422; the third transmission member 442 is used to drive the grinding wheel 45 to rotate;

[0034] A second groove 432 for avoiding the fiber braided cable 1 is provided on the side surface of the first mounting member 43, and a sharp portion 4321 for shearing the fiber braided cable 1 is provided on the upper side surface of the second groove 432; the grinding wheel 45 is arranged at one end of the first mounting member 43 away from the first transmission member 42 and is located below the second groove 432 provided on the first mounting member 43;

[0035] When the first driving member 41 drives the first transmission member 42 to move downward, the first transmission member 42 drives the first mounting member 43 and the first transmission assembly 44 to move downward through the first spiral groove 4312, so that the sharp portion 4321 shears the fiber braided cable 1, and at this time the second connecting member 422 is separated from the second spiral groove 4422; when the first driving member 41 drives the first transmission member 42 to move upward, the second connecting member 422 on the first transmission member 42 cooperates with the second spiral groove 4422, and the first connecting member 421 cooperates with the first spiral groove 4312, which is used to drive the grinding wheel 45 to rotate and drive the first mounting member 43 and the first transmission assembly 44 to move upward.

[0036] Specifically, the first driving member 41 can be a motor, preferably a lead screw stepping motor; the first transmission member 42 can be a lead screw, which is coaxially arranged on the output shaft of the lead screw stepping motor. Of course, it can also be the output shaft of the lead screw stepping motor. The first connecting member 421 and the second connecting member 422 are two cylindrical structures spaced apart at one end of the first transmission member 42 away from the first driving member 41. The first mounting member 43 is arranged on the bottom surface of the top plate 2 and is connected to the first transmission member 42 by means of a second transmission member 431; the second transmission member 431 can be a lead screw, and a thread is provided on the corresponding first through hole, and the two are connected by a thread. When the second transmission member 431 is a lead screw, a lead screw nut can also be arranged on the first mounting member 43, and the first mounting member 43 is connected to the second transmission member 431 through the lead screw nut; specifically, the lead screw nut is arranged on the left side surface of the first mounting member 43, and the grinding wheel 45 is arranged on the right side surface of the first mounting member 43. Of course, the second transmission member 431 can also be other structures, as long as the second transmission member 431 does not drive the first mounting plate 74 to rotate when rotating, and this embodiment does not limit this.

[0037] The first mounting member 43 can be a plate-like structure provided with a second groove 432. One side surface thereof is connected to the second transmission member 431, and the opposite side surface is connected to the grinding wheel 45. The second groove 432 is arranged in the middle of the first mounting member 43. In order to facilitate the installation of the fiber braided cable 1, the opening of the second groove 432 faces the front side of the fiber braided cable 1 experimental simulation device.

[0038] There can be multiple second mounting members 441, and the corresponding second through holes 21 are also multiple, and the second through holes 21 and the second mounting members 441 are arranged in one-to-one correspondence. The cross-section of the second mounting member 441 is a semi-circular arc structure. Specifically, in this embodiment, there are 4 second mounting members 441, and the 4 second mounting members form a space for accommodating the first transmission member 42, the second transmission member 431, the first connecting member 421 and the second connecting member 422 to avoid interference, so as to prevent the rotation of the first transmission member 42, the second transmission member 431, the first connecting member 421 and the second connecting member 422 from interfering with the inner side surface of the second through hole 21.

[0039] The third transmission member 442 can be a bevel gear, the tooth surface of which faces the first driving member 41. The third transmission member 442 is coaxially arranged with the first transmission member 42 and the second transmission member 431 through a third through hole 4421 and is in clearance fit with the first transmission member 42; the radius of the third through hole 4421 is larger than the radius of the first transmission member 42 and smaller than the rotation radius of the second connecting member 422, so that the first transmission member 42 can drive the third transmission member 442 to rotate through the second connecting member 422.

[0040] It can be understood that, in order to ensure that the first transmission member 42 can drive the first mounting member 43 and the first transmission assembly 44 to move downward, and drive the first mounting member 43 to move upward and the grinding wheel 45 to rotate, the first connecting member 421 provided on the first transmission member 42 is always located within the first spiral groove 4312 at the extreme upward movement position and the extreme downward movement position. When the first transmission member 42 drives the first mounting member 43 to move downward, at this time, the second connecting member 422 is disengaged from the second spiral groove 4422.

[0041] In this embodiment, by integrating the shear resistance experiment module and the wear resistance experiment module into one module, the experiment of shear strength and the experiment of wear resistance can be realized by using the same driving member. The structure is simple and it is also beneficial to reduce costs. In addition, without changing the installation position of the fiber braided cable, the tensile strength, shear resistance and wear resistance experiments can be carried out in sequence, avoiding the reduction of the accuracy of the experimental results due to the different stress conditions of the fiber braided cable caused by re-fixing the fiber braided cable. Furthermore, the tensile strength experiment and the wear resistance experiment, the tensile strength experiment and the shear resistance experiment can be carried out simultaneously, so as to simulate the use performance of the fiber braided cable in most usage scenarios.

[0042] Please refer to Figure 4 、 5 , the first transmission assembly 44 further includes a first bevel gear 445, a third mounting member 446, a first synchronous pulley 447, a second synchronous pulley 448, a first synchronous belt 449, a third synchronous pulley 450, a fourth synchronous pulley 451 and a second synchronous belt 452; a fourth through hole 22 is further provided on the top plate 2, and the third transmission member 442 is a bevel gear; the third transmission member 442 meshes with the first bevel gear 445; the third mounting member 446 passes through the fourth through hole 22 and is connected to the first mounting member, and the first synchronous pulley 447 and the first bevel gear 445 are coaxially arranged on the third mounting member 446; the second synchronous pulley 448 and the third synchronous pulley 450 are coaxially arranged on the first mounting member 43; the fourth synchronous pulley 451 and the grinding wheel 45 are coaxially arranged on the first mounting member 43; the first synchronous belt 449 passes through the fourth through hole 22 and is sleeved on the first synchronous pulley 447 and the second synchronous pulley 448, and the second synchronous belt 452 is sleeved on the third synchronous pulley 450 and the fourth synchronous pulley 451.

[0043] Specifically, the third mounting member 446 is a plate-like structure, which is vertically mounted on the top surface of the top plate 2. The first bevel gear 445 is disposed on the side surface of the third mounting member 446 facing the first transmission member 42, and the first synchronous pulley 447 is disposed on the side surface away from the first transmission member 42. Both are rotatably disposed on the third mounting member 446 through a transmission shaft. The third synchronous pulley 450 and the second synchronous pulley 448 are rotatably disposed on the first mounting member 43 through a transmission shaft. The fourth synchronous pulley 451 and the grinding wheel 45 are rotatably disposed on the first mounting member 43 through a transmission shaft. The setting of the fourth through hole 22 facilitates sleeving the first synchronous belt 449 on the first synchronous pulley 447 and the second synchronous pulley 448, and connecting the third mounting member 446 with the first mounting member 43.

[0044] Working principle of the shearing and grinding integrated experimental module: The first driving member 41 drives the first transmission member 42 to rotate. The rotation of the first transmission member 42 drives the first connecting member 421 to move within the first spiral groove 4312. At this time, the first connecting member 421 abuts against the side surface of the first spiral groove 4312, thereby driving the second transmission member 431 to rotate within the first through hole, enabling it to drive the first mounting member 43 to move downward, so that the sharp portion of the first mounting member 43 can shear the fiber braided cord 1. Since the second mounting member 441 and the third mounting member 446 are fixedly disposed on the first mounting member 43, when the first mounting member 43 moves downward, it also drives the second mounting member 441 and the third mounting member 446 to move downward, that is, drives the entire first transmission assembly 44 to move downward. When the first driving member 41 drives the first transmission member 42 to rotate and drives the first mounting member 43 to move upward, when the first mounting member 43 and the first transmission assembly 44 move upward a short distance, at this time, the grinding wheel 45 contacts the side surface of the fiber braided cord 1, and at this time, the second connecting member 422 cooperates with the second spiral groove 4422. Therefore, the rotation of the first transmission member 42 also drives the third transmission member 442 to rotate, thereby driving the grinding wheel 45 to rotate. Since the first driving member continuously drives the first mounting member 43 and the grinding wheel 45 is also constantly rotating, the grinding wheel 45 can continuously grind the fiber braided cord 1 and can ensure that different parts of the cross section of the fiber braided cord 1 can be ground.

[0045] Please refer to Figure 1 、 2, 6. The tensile test module 3 includes a second driving member 31, a fifth synchronous pulley 32, a sixth synchronous pulley 33, a seventh synchronous pulley 34, an eighth synchronous pulley 35, a third synchronous belt 36, a first gear 37, a second gear 38 and two wire winding wheels 39.

The second driving member 31 is arranged on the top surface of the top plate 2, and the fifth synchronous pulley is connected to the second driving member 31. The eighth synchronous pulley and the first gear 37 are coaxially arranged on the top surface of the top plate 2. The third synchronous belt 36 is sleeved on the fifth synchronous pulley 32, the sixth synchronous pulley 33, the seventh synchronous pulley 34 and the eighth synchronous pulley 35. The second gear 38 and one of the wire winding wheels 39 are coaxially arranged on the top plate 2, the sixth synchronous pulley 33 and one of the wire winding wheels 39 are coaxially arranged on the top plate 2, and the two wire winding wheels 39 are arranged on the bottom surface of the top plate 2. The first gear 37 and the second gear 38 are meshed. Specifically, the second driving member 31 can be a motor. The setting of the seventh synchronous pulley 34 enables the third synchronous belt 36 to avoid the setting positions of the first driving member 41 and the first transmission member 42. In addition, the seventh synchronous pulley 34 can also be used as an adjusting pulley to adjust the tension degree of the third synchronous belt 36. When the seventh synchronous pulley 34 is used as an adjusting pulley, a waist-shaped hole can be arranged on the top plate 2, and the seventh synchronous pulley 34 can adjust its position by adjusting the position on the waist-shaped hole, so as to adjust the position of the seventh synchronous pulley 34 to realize the tension degree of the third synchronous belt 36. In addition, by coaxially arranging the eighth synchronous pulley 35 and the first gear 37, and arranging the second gear 38 coaxial with the wire winding wheel 39 to be meshed with the first gear 37, the rotation directions of the two wire winding wheels 39 are made different, that is, when performing the tensile test, the two wire winding wheels 39 rotate in different directions, and then the two wire winding wheels 39 pull the fiber braided cable 1 in opposite directions.

Specifically, different types of water, such as seawater, can be contained in the water tank 51 according to different detection environment requirements. The spray head 55 is arranged in the receiving box 56, and after the receiving box 56 covers the fiber braided cable 1, the spray head 55 is directly opposite to the fiber braided cable 1, so as to simulate the outdoor humid environment for the fiber braided cable 1. A sealing structure can be arranged at the connection between the top of the receiving box 56 and the top plate 2, which can specifically be a sealing ring or other elastic deformation structures, so as to prevent the water in the water tank 51 from splashing out when spraying on the fiber braided cable 1, especially when the water in the water tank 51 is corrosive water, such as seawater, to prevent splashing out and corroding other structures outside the receiving box 56 or splashing onto the experimenters. The bottom of the cavity of the receiving box 56 can be set as an inclined plane, and its inclined plane converges to a point, and the water outlet pipe 54 is arranged at the converging point of the inclined plane, so as to facilitate the water in the receiving cavity to flow back into the water tank 51.

Specifically, since the fiber braided cable 1 needs to be replaced before the experiment is completed, after the experiment is completed, or during the experiment, the second driving component 8 is provided to drive the accommodating cavity to move up and down, so that the accommodating box 56 is separated from the top plate 2, and then the first driving component 7 is used to drive the accommodating box 56 and the second driving component 8 to move to the left side of the bottom plate 6 to move the accommodating box 56 away, facilitating the user to replace the fiber braided cable 1. After the replacement is completed, the first driving component 7 and the second driving component 8 are used to reset the accommodating box 56. In addition, since the water tank 51 does not move with the accommodating box 56 during the process of moving the accommodating box 56 by the first driving component 7, the water pipe collecting component 9 is provided to collect or release the water inlet pipe 53 and the water outlet pipe 54, avoiding the water inlet pipe 53 and the water outlet pipe 54 from being wound around structures such as the first driving component 7 and the second driving component 8 during the movement, resulting in a failure of the fiber braided cable experimental simulation device.

[0048] The first driving component 7 includes a third driving member 71, a lead screw 72, a guide rail 73, and a mounting plate 74; the second driving component 8 is arranged on the mounting plate 74, and the accommodating box 56 is arranged on the second driving component 8; the lead screw 72 is connected to the third driving member 71, the mounting plate 74 is connected to the lead screw 72, and the mounting plate 74 is also slidably connected to the guide rail 73; the water pipe collecting component 9 is in transmission connection with the lead screw 72. Specifically, the first driving component 7 drives the second driving component 8 and the accommodating box 56 to move as a whole. Two guide rails 73 can be provided, and the two guide rails 73 are symmetrically arranged on one side of the lead screw 72 respectively. The water pipe collecting component 9 is in transmission connection with the lead screw 72, that is, when the third driving member 71 rotates, it synchronously drives the water pipe collecting component 9 to move, so that the water pipe collecting component 9 synchronously collects or releases the water inlet pipe 53 and the water outlet pipe 54. The third driving member 71 can be a motor, and of course, it can also be other driving elements, and this embodiment does not limit this.

Specifically, the second bevel gear 91 is fixedly arranged on the lead screw 72. A lead screw nut is arranged on the mounting plate, and the lead screw 72 is connected to the mounting plate through the lead screw nut. When the lead screw 72 rotates and drives the second driving assembly 8 and the accommodating box 56 to move leftward, the lead screw 72 synchronously drives the second bevel gear 91 to rotate, thereby driving the fourth gear 94 to rotate counterclockwise. The counterclockwise rotation of the fourth gear 94 can drive the water inlet pipe collecting member 95 and the water outlet pipe collecting member 96 to rotate counterclockwise to synchronously release the water inlet pipe 53 and the water outlet pipe 54; when the lead screw 72 rotates and drives the second driving assembly 8 and the accommodating box 56 to move rightward, the lead screw 72 synchronously drives the second bevel gear 91 to rotate, thereby driving the fourth gear 94 to rotate clockwise. The clockwise rotation of the fourth gear 94 can drive the water inlet pipe collecting member 95 and the water outlet pipe collecting member 96 to rotate clockwise to synchronously collect the water inlet pipe 53 and the water outlet pipe 54.

[0052] Installation steps of the fiber braided cable: Drive the receiving box 56 to move downward through the movement of the second driving component 8, so that the receiving box 56 moves away from the top plate 2; then drive the screw rod 72 to rotate through the third driving member 71, so as to drive the receiving box 56 to move leftward along the guide rail 73 and drive the water pipe collecting component 9 to rotate, so that the water pipe collecting component 9 releases the water inlet pipe 53 and the water outlet pipe 54; then fix the two ends of the fiber braided cable to one of the winding wheels 39 respectively; finally, drive the screw rod 72 to rotate through the third driving member 71, and then drive the receiving box 56 to move rightward along the guide rail 73 and drive the water pipe collecting component 9 to rotate, so that the water pipe collecting component 9 collects the water inlet pipe 53 and the water outlet pipe 54, and the second driving component 8 moves to drive the receiving box 56 to move upward, so that the receiving box 56 contacts the top plate 2.

[0053] Tensile strength test steps: Drive the third synchronous belt to rotate on the fifth synchronous belt pulley 32, the sixth synchronous belt pulley 33, the seventh synchronous belt pulley 34, and the eighth synchronous belt pulley 35 through the rotation of the second driving member 31, and then drive the first gear 37 and the second gear 38 to rotate, so that the two winding wheels 39 rotate in opposite directions, and then the two winding wheels 39 respectively wind the fiber braided cable 1 to pull the fiber braided cable 1 at both ends.

[0054] Shear strength test steps: Drive the first transmission member 42 to move downward through the rotation of the first driving member 41, and the first connecting member 421 drives the first mounting member 43 and the first transmission assembly 44 to move downward through the first spiral groove 4312, so that the sharp part 4321 shears the fiber braided cable 1.

[0055] Abrasion resistance strength test steps: Drive the first transmission member 42 to move upward through the rotation of the first driving member 41, and the first connecting member 421 drives the first mounting member 43 and the first transmission assembly 44 to move upward through the first spiral groove 4312. During the upward movement, the second connecting member 422 cooperates with the second spiral groove 4422, and the second connecting member 422 drives the third transmission member and the corresponding pulley to rotate through the second spiral groove 4422, and then drives the grinding wheel 45 to rotate, so that the grinding wheel 45 rubs the fiber braided cable 1.

[0056] Disassembly steps of the fiber braided cable: The second driving component 8 moves to drive the accommodation box 56 to move downward, so that the accommodation box 56 moves away from the top plate 2; then the third driving member 71 drives the lead screw 72 to rotate, so as to drive the accommodation box 56 to move leftward along the guide rail 73 and drive the water pipe collecting component 9 to rotate, so that the water pipe collecting component 9 releases the water inlet pipe 53 and the water outlet pipe 54; then the two ends of the fiber braided cable 1 are respectively disassembled from the fixed winding wheel 39; finally, the third driving member 71 drives the lead screw 72 to rotate, and then drives the accommodation box 56 to move rightward along the guide rail 73 and drives the water pipe collecting component 9 to rotate, so that the water pipe collecting component 9 collects the water inlet pipe 53 and the water outlet pipe 54, and the second driving component 8 moves to drive the accommodation box 56 to move upward, so that the accommodation box 56 contacts the top plate 2.

In addition, when the tensile strength test, the shear strength test or the abrasion resistance test step is carried out alone, or when the tensile strength test step and the shear strength test step or the tensile strength test and the abrasion resistance test step are carried out simultaneously, the water pump 52 can be turned on to pump out the water in the water tank 51, and the fiber braided cable 1 can be sandblasted by using the nozzle 55 to simulate a humid or rainy environment.
