Description

Technical Field

[0001] The invention belongs to the field of fiber braided rope simulation experiments, and in particular relates to a fiber braided rope experiment simulation device and method. Background Art

[0002] In many fields such as ships, machinery, construction, and aerospace, fiber braided cables have emerged as an indispensable structural material, and are highly respected for their light weight, excellent strength, and extraordinary corrosion resistance.

[0003] In the design process of fiber braided ropes, experimental simulation devices play a vital role. These devices are specially used to simulate the mechanical properties and durability of fiber braided ropes in the use environment, especially under extreme conditions such as cutting, abrasion, humidity and heat, covering shear strength, abrasion resistance and tensile strength. However, most experimental simulation devices on the market can only simulate tests on a single mechanical property in a specific scenario. This means that in order to comprehensively evaluate the various mechanical properties of fiber braided ropes, researchers have to prepare a variety of different simulation experimental devices, which undoubtedly greatly increases the cost and complexity of the experiment.

[0004] In addition, although there is an experimental simulation device that integrates multiple mechanical properties 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 run at the same time. Therefore, when it is necessary to simulate the mechanical properties of fiber braided ropes in complex scenarios, such as first subjecting them to a certain amount of shear force and then to a certain degree of wear, the existing experimental simulation device is incapable of doing so. The experimenters had to first remove the fiber braided rope from the module for the shear strength test, and then install it on the module for the wear strength test for testing. This process not only increases the workload of the experimenters, but also the force conditions of the fiber braided rope may change during the disassembly and reinstallation process, thereby affecting the accuracy of the experimental results.

[0029] Specifically, the first driving member 41 can be a motor, preferably a screw stepper motor; the first transmission member 42 can be a screw, which is coaxially arranged on the output shaft of the screw stepper motor, and of course it can also be the output shaft of the screw stepper motor. The first connecting member 421 and the second connecting member 422 are two cylindrical structures arranged at intervals on 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 the second transmission member 431; the second transmission member 431 can be a screw, and the corresponding first through hole is provided with a thread, and the two are connected by threads. When the second transmission member 431 is a screw, a screw nut can also be provided on the first mounting member 43, and the first mounting member 43 is connected to the second transmission member 431 through the screw nut; specifically, the screw nut is arranged on the left side of the first mounting member 43, and the grinding wheel 45 is arranged on the right side of the first mounting member 43. Of course, the second transmission member 431 may 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 impose any limitation on this.

[0030] The first mounting member 43 can be a plate-like structure provided with a second groove 432, one side of which is connected to the second transmission member 431, and the other opposite side 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 rope 1, the second groove 432 opens toward the front side of the fiber braided rope 1 experimental simulation device.

[0031] 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 one by one, and the cross section of the second mounting members 441 is a semicircular arc structure. Specifically, in this embodiment, there are four second mounting members 441, and the four 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 the rotation of the first transmission member 42, the second transmission member 431, the first connecting member 421 and the second connecting member 422, which will interfere with the inner side surface of the second through hole 21.

[0032] The third transmission member 442 can be a bevel gear, and its tooth surface is arranged toward 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 the third through hole 4421, and is clearance-matched 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.

[0033] 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 in the first spiral groove 4312 at the limit position of upward movement and the limit position of downward movement. 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.

[0034] This embodiment integrates the shear test module and the wear test module into one module, and uses the same drive member to realize the shear strength test and the wear strength test, which has a simple structure and is also conducive to reducing costs. In addition, without changing the installation position of the fiber braided rope, the tensile, shear and wear strength tests can be carried out in sequence to avoid the different stress conditions of the fiber braided rope due to re-fixing the fiber braided rope, which leads to a decrease in the accuracy of the test results. Furthermore, the tensile strength test and the wear strength test, the tensile strength test and the shear strength test can be carried out simultaneously, so as to simulate the performance of the fiber braided rope in most usage scenarios.

[0035] See also Figure 4 , 5 The first transmission assembly 44 also 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 also provided on the top plate 2, and the third transmission member 442 is a bevel gear; the third transmission member 442 is meshed 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 The synchronous pulley 447 is coaxially arranged on the third mounting member 446 with the first bevel gear 445; 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.

[0036] 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 arranged on the side of the third mounting member 446 facing the first transmission member 42, and the first synchronous pulley 447 is arranged on the side away from the first transmission member 42, and both are rotatably arranged on the third mounting member 446 through the transmission shaft. The third synchronous pulley 450 and the second synchronous pulley 448 are rotatably arranged on the first mounting member 43 through the transmission shaft. The fourth synchronous pulley 451 and the grinding wheel 45 are rotatably arranged on the first mounting member 43 using the transmission shaft. The fourth through hole 22 is arranged to facilitate the first synchronous belt 449 to be sleeved on the first synchronous pulley 447 and the second synchronous pulley 448, and to connect the third mounting member 446 with the first mounting member 43.

[0037] Working principle of the shearing and grinding integrated experimental module: the first driving member 41 drives the first transmission member 42 to rotate, and the rotation of the first transmission member 42 drives the first connecting member 421 to move in the first spiral groove 4312. At this time, the first connecting member 421 abuts against the side of the first spiral groove 4312, thereby driving the second transmission member 431 to rotate in the first through hole, so that it can drive the first mounting member 43 to move downward, so that the sharp part of the first mounting member 43 can shear the fiber braided rope 1. Since the second mounting member 441 and the third mounting member 446 are fixedly arranged on the first mounting member 43, the downward movement of the first mounting member 43 also drives the second mounting member 441 and the third mounting member 446 to move downward, that is, drives the first transmission assembly 44 to move downward as a whole. When the first driving member 41 drives the first transmission member 42 to rotate and drives the first mounting member 43 to move upward, after the first mounting member 43 and the first transmission assembly 44 move upward a short distance, the grinding wheel 45 contacts the side of the fiber braided rope 1, and the second connecting member 422 cooperates with the second spiral groove 4422, so the rotation of the first transmission member 42 also drives the third transmission member 442 to rotate, and then drives the grinding wheel 45 to rotate. Since the first driving member continuously drives the first mounting member 43, and the grinding wheel 45 also rotates continuously, the grinding wheel 45 can continuously grind the fiber braided rope 1, and it can be ensured that different parts of the cross section of the fiber braided rope 1 can be ground.

[0038] See also Figure 1 , 26. 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 winding wheels 39; the fifth synchronous pulley 32, the sixth synchronous pulley 33, the seventh synchronous pulley 34 and the eighth synchronous pulley 35 are arranged on the top surface of the top plate 2 at intervals; the second driving member 31 is arranged on the top surface of the top plate 2, and the fifth pulley is connected to the second driving member 31; the eighth synchronous wheel is coaxially arranged on the top surface of the top plate 2 with the first gear 37; 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 winding wheels 39 are coaxially arranged on the top plate 2, the sixth synchronous pulley 33 and one of the winding wheels 39 are coaxially arranged on the top plate 2, and the two 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 seventh synchronous pulley 34 is set so that the third synchronous belt 36 avoids the setting position 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 wheel to adjust the tension of the third synchronous belt 36. When the seventh synchronous pulley 34 is used as an adjusting wheel, a waist-shaped hole can be set on the top plate 2. The seventh synchronous pulley 34 can adjust the position of the seventh synchronous pulley 34 by adjusting the position set on the waist-shaped hole to achieve the tension of the third synchronous belt 36. In addition, by setting the eighth synchronous pulley 35 and the first gear 37 coaxially, and setting the second gear 38 coaxial with the winding wheel 39 to mesh with the first gear 37, the rotation directions of the two winding wheels 39 can be changed to different, that is, during the tensile test, the two winding wheels 39 rotate in different directions, and then the two winding wheels 39 pull the fiber braided rope 1 in opposite directions.

The nozzle 55 is arranged in the receiving box 56, and after the receiving box 56 is covered on the fiber braided rope 1, the nozzle 55 is directly facing the fiber braided rope 1, so as to simulate the outdoor humid environment for the fiber braided rope 1. A sealing structure can be provided at the connection between the top of the receiving box 56 and the top plate 2, which can be a sealing ring or other elastic deformation structure to prevent the water in the water tank 51 from splashing when it is sprayed on the fiber braided rope 1, especially when the water in the water tank 51 is corrosive water, such as seawater, to avoid splashing out to corrode other structures outside the receiving box 56 or splashing on the experimenter. The bottom of the cavity of the receiving box 56 can be set as an inclined surface, and the inclined surface converges into a point. The water outlet pipe 54 is set at the convergence point of the inclined surface, so as to return the water in the receiving cavity to the water tank 51. One side of the containing box 56 can be made of transparent material, such as acrylic material, and specifically can be the side of the containing box 56 close to the front end of the fiber braided rope 1 experimental simulation device, so that the experimenter can observe the progress of the experiment in real time.

Specifically, since the fiber braided rope 1 needs to be replaced before, after or during the experiment, the second drive assembly 8 is arranged to drive the receiving chamber to move up and down so that the receiving box 56 is separated from the top plate 2, and then the first drive assembly 7 is used to drive the receiving box 56 and the second drive assembly 8 to move to the left side of the bottom plate 6 to remove the receiving box 56, so that the user can replace the fiber braided rope 1. After the replacement is completed, the receiving box 56 is reset by using the first drive assembly 7 and the second drive assembly 8. In addition, since the water tank 51 does not move with the containing box 56 during the process of moving the containing box 56 using the first driving component 7, a water pipe collecting component 9 is provided to collect or release the water inlet pipe 53 and the water outlet pipe 54 to prevent the water inlet pipe 53 and the water outlet pipe 54 from being entangled with the first driving component 7, the second driving component 8 and other structures during the movement, thereby causing a failure of the fiber braided rope experimental simulation device.

A screw nut is arranged on the mounting plate, and the screw rod 72 is connected to the mounting plate through the screw nut. When the screw rod 72 rotates and drives the second drive assembly 8 and the accommodating box 56 to move to the left, the screw rod 72 synchronously drives the second bevel gear 91 to rotate, and then drives the fourth gear 94 to rotate counterclockwise. The counterclockwise rotation of the fourth gear 94 can drive the inlet pipe collecting piece 95 and the outlet pipe collecting piece 96 to rotate counterclockwise to synchronously release the inlet pipe 53 and the outlet pipe 54; when the screw rod 72 rotates and drives the second drive assembly 8 and the accommodating box 56 to move to the right, the screw rod 72 synchronously drives the second bevel gear 91 to rotate, and then drives the fourth gear 94 to rotate clockwise.

[0044] On the other hand, the present invention provides a fiber braided rope experimental simulation method, including the above-mentioned fiber braided rope experimental simulation device, and the braiding method includes: Installation steps of the fiber braided rope: the second driving component 8 is used to drive the receiving box 56 to move downward, so that the receiving box 56 is moved away from the top plate 2; the third driving member 71 is used to drive the screw rod 72 to rotate, so as to drive the receiving box 56 to move to the left 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 rope are respectively fixed on one of the winding wheels 39; finally, the third driving member 71 drives the screw rod 72 to rotate, thereby driving the receiving box 56 to move to the right 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, driving the receiving box 56 to move upward, so that the receiving box 56 contacts the top plate 2.

[0045] Tensile strength test steps: The second driving member 31 rotates to drive the third belt to rotate on the fifth synchronous pulley 32, the sixth synchronous pulley 33, the seventh synchronous pulley 34, and the eighth synchronous pulley 35, thereby driving 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 are respectively wound around the fiber braided rope 1 to pull the fiber braided rope 1 to both ends.

[0046] Shear strength test steps: The first driving member 41 rotates to drive the first transmission member 42 to move downward, 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 portion 4321 shears the fiber braided rope 1.
