The performance of the rope is a key technical point affecting the overall performance of rope-driven robots. Therefore, the testing and verification of rope performance has always been an important part of rope drive.

[0003] Currently, the industry offers a rope tension testing device. During operation, a motor drives a sliding plate to move back and forth within a groove, simulating the swaying of a rope during use.

[0089] The following will combine Figures 3 to 16 For a detailed description of the rope testing device provided in this application, please refer to [link / reference]. Figure 3 , Figure 3 This is a schematic diagram of a rope testing device in an embodiment of this application. Specifically,

[0090] The rope testing device includes: a base 10, an active component 20, and a first driven component 30;

[0091] The active component 20 and the first driven component 30 are disposed on the base 10. The active component 20 includes an active rope wheel 201, a drive motor 202 and an active end encoder 203. The first driven component 30 includes a first driven rope wheel 301, a first weight component 302 and a first driven end encoder 303.

[0092] The first driven pulley 301 is used to wind one end of the rope 40 to be tested;

[0093] The drive pulley 201 is used to wind the other end of the rope 40 to be tested;

[0094] The first weight assembly 302 is disposed on the first driven rope pulley 301, and the first weight assembly 302 is used to provide load;

[0095] The drive motor 202 is connected to the drive pulley 201 and the drive end encoder 203. The drive motor 202 is used to drive the drive pulley 201 to rotate.

[0096] The active end encoder 203 is used to read the first rotation angle of the rope 40 under test;

[0097] The first driven end encoder 303 is used to read the second rotation angle of the rope 40 to be tested.

[0098] In one or more embodiments, a rope testing apparatus is described. As described above, the rope testing apparatus can be used to detect the creep and endurance of the rope 40 under test.

[0099] Specifically, for clarity, please refer to [link / reference]. Figure 3 and Figure 4 As shown in the figure, a groove is provided on the base 10, into which the active component 20 and the first driven component 30 can be inserted and fixed to the base 10. This achieves both component fixation and allows the user to easily adjust the position of the components on the base 10.

[0100] The test rope 40 is wound around the driving rope pulley 201 and the first driven rope pulley 301. It is understood that the middle portion of the test rope 40 may also be wound around the pulley assembly 50; this is not limited here. The driving rope pulley 201 is equipped with a driving end encoder 203, capable of reading the first rotation angle of the test rope 40. The first driven rope pulley 301 is equipped with a first driven end encoder 303, capable of reading the second rotation angle of the test rope 40.

[0101] Since the creep variable is tested under normal operating conditions, a load still needs to be placed at the end, that is, a first weight assembly 302 is placed on the first driven pulley 301, and the first weight assembly 302 is used to provide the load.

[0102] After installing the components and adjusting the rope tension, the initial values ​​of the encoders at both ends (i.e., the active encoder 203 and the first driven encoder 303) need to be adjusted before starting the drive motor 202. The drive motor 202 is connected to the active pulley 201 and the active encoder 203, and all three are on the same axis. The drive motor 202 drives the active pulley 201 to rotate, thus causing the rope 40 under test to move back and forth. After a period of movement, the difference between the first and second rotation angles can be determined by reading the first rotation angle and the second rotation angle, thereby measuring the creep of the rope 40 under test.

[0103] Based on this, the endurance of the rope 40 under test can also be measured. For example, the endurance can be determined based on creep, or based on the fracture condition of the rope 40 under test, or based on the plastic deformation condition of the rope 40 under test; no limitation is made here.

[0104] This application provides a rope testing device. Using this device, the creep deformation of the rope under test can be calculated by utilizing a first rotation angle read by the active end encoder and a second rotation angle read by the driven end encoder. Simultaneously, the endurance of the rope under test can also be determined by obtaining the creep deformation. Therefore, the rope testing device provided in this application can perform multiple performance tests, is not only easy to operate but also improves testing efficiency.

[0105] Optionally, in the above Figures 3 to 16 Based on any of the corresponding embodiments, in another optional embodiment of the rope testing device provided in this application, the active component 20 further includes a motor bracket 204 and the drive motor 202 has a transmission rod 2021.

[0106] The motor bracket 204 has a through hole 2041, and the transmission rod 2021 passes through the through hole 2041 and is fixedly connected to the drive rope wheel 201.

[0107] The transmission rod is used to drive the drive pulley 201 to rotate along the same axis when the drive motor 202 is working;

[0108] The drive pulley 201 is located inside the motor bracket 204, and the drive motor 202 is located outside the motor bracket 204;

[0109] The motor bracket 204 is mounted on the base 10.

[0110] In one or more embodiments, a rope testing device is described. As described above, the active component 20 includes not only the active rope pulley 201, the drive motor 202, and the active end encoder 203, but also the motor bracket 204.

[0111] Specifically, for clarity, please refer to [link / reference]. Figure 6 As shown in the figure, the drive motor 202 has a protruding transmission rod 2021 below it, which extends into a through hole 2041 on the motor bracket 204. Based on this, the transmission rod 2021 passes through the through hole 2041 and is fixedly connected to the drive pulley 201. When the drive motor 202 is working, the transmission rod 2021 can rotate in one direction, thereby driving the drive pulley 201 to rotate coaxially in the same direction.

[0112] To achieve better fixation, both the drive pulley 201 and the drive end encoder 203 can be placed inside the motor bracket 204, while the drive motor 202 can be placed outside the motor bracket 204. Therefore, the motor bracket 204 can support the drive motor 202, and the motor bracket 204 can be fixed to the base 10.

[0113] It should be noted that this application does not limit the way the motor bracket 204 is fixed on the base 10.

[0114] Secondly, this application provides a rope testing device. Using this device, a motor bracket supports the drive motor, achieving a stable active component while the drive motor is operating.

[0115] Optionally, in the above Figures 3 to 16 Based on any of the corresponding embodiments, in another optional embodiment of the rope testing device provided in this application, the active component 20 includes a first intermediate component 205 and an encoder base 206.

[0117] The encoder base 206 is disposed on the base 10, or the encoder base 206 is disposed inside the motor bracket 204, and the encoder base 206 is used to support the active end encoder 203.

[0118] In one or more embodiments, a rope testing device is described. As described above, the active component 20 includes not only the active rope pulley 201, the drive motor 202, the active end encoder 203, and the motor bracket 204, but also a first intermediate component 205 and an encoder base 206.

[0119] Specifically, for clarity, please refer to [the relevant documentation / reference]. Figure 6As shown in the figure, a first intermediate component 205 is added between the active pulley 201 and the active encoder 203. The active encoder 203 is fixed to the encoder base 206. For example, if the bottom of the motor bracket 204 is hollow, the encoder base 206 can be directly fixed to the base 10. For example, if the bottom of the motor bracket 204 is a flat plate, the encoder base 206 can be directly fixed to the flat plate of the motor bracket 204, that is, it is located inside the motor bracket 204.

[0120] It should be noted that this application does not limit the material of the first intermediate component 205.

[0121] Secondly, this application provides a rope testing device. Using this device, a first intermediate component is added between the active rope pulley and the active end encoder. This serves two purposes: firstly, it fixes the active rope pulley and the active end encoder, ensuring they are on the same axis; secondly, it reduces friction between the active rope pulley and the active end encoder, thus mitigating wear on the components.

[0122] Optionally, in the above Figures 3 to 16 Based on any of the corresponding embodiments, in another optional embodiment of the rope testing device provided in this application, the first driven component 30 further includes a second intermediate component 304 and a support 305 from the first driven end;

[0123] The first driven pulley 301 is connected to the first driven end encoder 303 via the second intermediate component 304;

[0124] The first driven end bracket 305 is disposed on the base 10, and the first driven end encoder 303 is disposed on the first driven end bracket 305.

[0125] In one or more embodiments, a rope testing device is described. As can be seen from the foregoing description, the first driven component 30 includes not only the first driven rope pulley 301, the first weight component 302, and the first driven end encoder 303, but also the second intermediate component 304 and the first driven end bracket 305.

[0126] Specifically, for clarity, please refer to [link / reference]. Figure 7 As shown in the figure, a second intermediate component 304 is added between the first driven pulley 301 and the first driven end encoder 303. The first driven end encoder 303 is fixed on the first driven end bracket 305, and the first driven end bracket 305 is directly fixed on the base 10.

[0127] It should be noted that this application does not limit the material of the first intermediate component 205.

[0128] Secondly, this application provides a rope testing device. Using this device, a second intermediate component is added between the first driven sheave and the first driven encoder. This serves two purposes: firstly, it fixes the first driven sheave and the first driven encoder, ensuring they are on the same axis; secondly, it reduces friction between the first driven sheave and the first driven encoder, thus mitigating wear on the components.

[0129] Optionally, in the above Figures 3 to 16 Based on any of the corresponding embodiments, in another optional embodiment of the rope testing device provided in this application, the first weight assembly 302 includes a weight support frame 3021 and a weight block 3022;

[0130] A support rod 3033 is provided on the weight support frame 3021;

[0131] The weight block 3022 is fitted onto one end of the support rod 3033, and the weight block 3022 is detachably connected to the weight support frame 3021.

[0132] In one or more embodiments, a rope testing apparatus is described. As can be seen from the foregoing, in actual testing, a load needs to be applied to the end (i.e., the driven end) to simulate the normal operation of the rope 40 under test.

[0133] Specifically, for clarity, please refer to [the relevant documentation / reference]. Figure 7 As shown in the figure, a first weight assembly 302 is added above the first driven pulley 301. The weight support frame 3021 has a support rod 3033, and the weight block 3022 has a through hole through which the support rod 3033 can pass. Therefore, by fitting the weight block 3022 onto one end of the support rod 3033, the corresponding load can be increased.

[0134] Furthermore, this application provides a rope testing device. Using this device, the load value can be adjusted by adding or removing weights, thereby increasing the flexibility of the test.

[0135] Optionally, in the above Figures 3 to 16 Based on any of the corresponding embodiments, in another optional embodiment of the rope testing device provided in this application, the rope testing device further includes a second driven component 60 and a first rope pulley assembly 501;

[0137] The second driven end bracket 602 is disposed on the base 10;

[0138] The grinding wheel 601 is mounted on the second driven end bracket 602, and the grinding wheel 601 is used to wind one end of the rope 40 to be tested.

[0139] The active pulley 201 is also used to wind the other end of the rope 40 to be tested;

[0140] The auxiliary rope wheel 5011 is equipped with a pressure sensor 5012. The auxiliary rope wheel 5011 is used to wind the rope 40 to be tested.

[0142] In one or more embodiments, a rope testing device is described. As described above, the rope testing device can be used to detect the abrasion resistance of a rope 40 to be tested. Based on this, the rope testing device also needs to be provided with a pulley assembly 50 and a second driven assembly 60, wherein the pulley assembly 50 includes at least one first pulley assembly 501.

[0143] Specifically, for clarity, please refer to [link / reference]. Figure 8 As shown in the figure, a groove is provided on the base 10, into which the second driven component 60 and the pulley component 50 can be embedded and fixed to the base 10. This achieves both component fixation and allows the user to easily adjust the position of the components on the base 10.

[0144] The test rope 40 is wound around the driving rope pulley 201 and the grinding wheel 601. The grinding wheel 601 is mounted on the second driven end bracket 602, and the second driven assembly 60 is mounted on the base 10. It is understood that the middle portion of the test rope 40 also needs to be wound around the auxiliary rope pulley 5011. A pressure sensor 5012 (e.g., a six-dimensional force sensor) is installed inside the auxiliary rope pulley 5011, which can measure the pressure between the test rope 40 and the auxiliary rope pulley 5011.

[0145] Understandably, the pulley assembly 50 may also include at least one second pulley assembly 502, and the middle portion of the test rope 40 may also be wound around the auxiliary pulley 5021 of the second pulley assembly 502.

[0146] After the components are installed and the rope tension is adjusted, the drive motor 202 can be started. The drive motor 202 drives the active rope pulley 201 to rotate, thereby causing the test rope 40 to move back and forth. As a result, the test rope 40 will experience wear between itself and the grinding wheel 601. When the wear exceeds a threshold, the pressure between the test rope 40 and the auxiliary rope pulley 5011 will also decrease. Based on this, the abrasion resistance of the test rope 40 can be measured.

[0147] Secondly, this application provides a rope testing device. Using this device, the abrasion resistance of the rope under test can be calculated by utilizing the pressure between the rope and the auxiliary rope pulley. Therefore, the rope testing device provided in this application can perform multiple performance tests, is not only easy to operate, but also improves testing efficiency.

[0148] Optionally, in the above Figures 3 to 16 Based on any of the corresponding embodiments, in another optional embodiment of the rope testing device provided in this application, the rope testing device further includes a third driven component 70 and a first rope pulley assembly 501;

[0149] The third driven component 70 is disposed on the base 10. The third driven component 70 includes a rotating block 701, a first encoder 702 and a third driven end bracket 703. The first rope wheel assembly 501 includes an auxiliary rope wheel 5011 and a pressure sensor 5012.

[0150] The auxiliary rope wheel 5011 is equipped with a pressure sensor 5012. The auxiliary rope wheel 5011 is used to wind the rope 40 to be tested.

[0151] The rotating block 701 is used to wrap around one end of the rope 40 to be tested;

[0152] The active pulley 201 is also used to wind the other end of the rope 40 to be tested;

[0153] The first encoder 702 is mounted on the third driven end bracket 703. The first encoder 702 is used to read the rotational angular velocity of the rotating block 701.

[0154] Pressure sensor 5012 is used to read the pressure between the test rope 40 and the auxiliary rope pulley 5011.

[0155] In one or more embodiments, a rope testing device is described. As described above, the rope testing device can be used to detect the coefficient of friction of the rope 40 to be tested. Based on this, the rope testing device also needs to be provided with a pulley assembly 50 and a third driven assembly 70, wherein the pulley assembly 50 includes at least one first pulley assembly 501.

[0156] Specifically, for clarity, please refer to [link / reference]. Figure 9 As shown in the figure, a groove is provided on the base 10, into which the third driven component 70 and the pulley component 50 can be embedded and fixed to the base 10. This achieves both component fixation and allows the user to easily adjust the position of the components on the base 10.

[0157] The test rope 40 is wound around the drive pulley 201 and the rotating block 701. The rotating block 701 can be positioned above the first encoder 702, and the two can be connected by an intermediate component. The first encoder 702 is mounted on the third driven end bracket 703, which is mounted on the base 10. It is understood that the middle portion of the test rope 40 also needs to be wound around the auxiliary pulley 5011. A pressure sensor 5012 is installed inside the auxiliary pulley 5011, which can measure the pressure between the test rope 40 and the auxiliary pulley 5011.

[0158] Understandably, the pulley assembly 50 may also include at least one second pulley assembly 502, and the middle portion of the test rope 40 may also be wound around the auxiliary pulley 5021 of the second pulley assembly 502.

[0159] After the components are installed and the rope tension is adjusted, the drive motor 202 can be started. The drive motor 202 drives the active rope pulley 201 to rotate, thereby causing the test rope 40 to move back and forth. As a result, the test rope 40 drives the rotating block 701 to rotate. Based on the rotational angular velocity read by the first encoder 702, the pressure between the test rope 40 and the auxiliary rope pulley 5011, and the mass and radius of the rotating block 701, the coefficient of friction of the test rope 40 can be measured.

[0160] Secondly, this application provides a rope testing device. Using this device, the coefficient of friction of the rope under test can be calculated based on the pressure between the rope and the auxiliary rope pulley, as well as the relevant parameters of the rotating block. Therefore, the rope testing device provided in this application can perform multiple performance tests, is not only easy to operate, but also improves testing efficiency.

[0163] Washer 5014 is wrapped around screw 5013.

[0164] In one or more embodiments, a rope testing apparatus is described. As described above, the rope pulley assembly 50 includes at least one first rope pulley assembly 501, and the following description will take a single first rope pulley assembly 501 as an example.

[0165] Specifically, for clarity, please refer to [link / reference]. Figure 10 and Figure 11 As shown in the figure, the first rope pulley assembly 501 includes not only an auxiliary rope pulley 5011 and a pressure sensor 5012, but also a screw 5013 and a washer 5014. One end of the screw 5013 can be mounted on the base 10, while the other end of the screw 5013 is fitted with the auxiliary rope pulley 5011. The pressure sensor 5012 can be placed in the middle of the auxiliary rope pulley 5011. The washer 5014 is wrapped around the outside of the screw 5013.

[0166] It should be noted that this application does not limit the material of gasket 5014.

[0167] Furthermore, this application provides a rope testing device. Using this device, a first rope pulley assembly is constructed, which can test the pressure between the rope under test and the auxiliary rope pulley, thereby providing corresponding parameters for performance testing and improving the feasibility and operability of the solution. In addition, wrapping the screw with a washer can protect the screw surface and reduce corrosion of the screw body.

[0168] Optionally, in the above Figures 3 to 16 Based on any of the corresponding embodiments, in another optional embodiment of the rope testing device provided in this application, the rope testing device further includes a second rope pulley assembly 502;

[0169] The second rope pulley assembly 502 is disposed on the base 10. The second rope pulley assembly 502 includes an auxiliary rope pulley 5021, a screw 5022, and a washer 5023.

[0171] Washer 5023 is wrapped around screw 5022.

[0172] In one or more embodiments, a rope testing apparatus is described. As described above, the rope pulley assembly 50 includes at least one second rope pulley assembly 502, and the following description will take a single second rope pulley assembly 502 as an example.

[0173] Specifically, for clarity, please refer to [link / reference]. Figure 12 and Figure 13 As shown in the figure, the second pulley assembly 502 includes not only the auxiliary pulley 5021, but also a screw 5022 and a washer 5023. One end of the screw 5022 can be mounted on the base 10, while the other end of the screw 5022 is fitted with the auxiliary pulley 5021. The washer 5023 is wrapped around the outside of the screw 5022.

[0174] It should be noted that this application does not limit the material of gasket 5023.

[0175] Furthermore, this application provides a rope testing device. Using this device, the second rope pulley assembly is constructed, facilitating rope winding operations and improving winding flexibility. Additionally, wrapping the screw with a washer protects the screw surface and reduces corrosion to the screw body.

[0176] Optionally, in the above Figures 3 to 16 Based on any of the corresponding embodiments, in another optional embodiment of the rope testing device provided in this application, the base 10 is provided with a groove;

[0177] A slidable first pulley assembly 501 and a slidable second pulley assembly 502 are provided in the groove.

[0178] In one or more embodiments, a rope testing apparatus is described. As described above, the rope pulley assembly 50 includes at least one first rope pulley assembly 501 and at least one second rope pulley assembly 502, and the rope pulley assembly 50 is disposed on the base 10.

[0179] Specifically, for clarity, please refer to [the relevant documentation / reference]. Figure 8 and Figure 9 As shown in the figure, a groove is provided on the base 10. The first rope wheel assembly 501 and the second rope wheel assembly 502 included in the rope wheel assembly 50 are both locked in the groove of the base 10. The distance can be adjusted by sliding the first rope wheel assembly 501 and the second rope wheel assembly 502, thereby adjusting the pressure between the auxiliary rope wheel and the rope 40 to be tested.

[0180] It should be noted that after adjusting the positions of the first rope wheel assembly 501 and the second rope wheel assembly 502, they can be locked in the groove to achieve the effect of fixing the position.

[0181] Furthermore, in this embodiment, a rope testing device is provided. Using this device, the distance between the components in the rope pulley assembly can be adjusted to change the pressure between the auxiliary rope pulley and the rope under test, thereby increasing the flexibility of the test.

[0182] Optionally, in the above Figures 3 to 16 Based on any of the corresponding embodiments, in another optional embodiment of the rope testing device provided in this application, the rope testing device further includes a fourth driven component 80;

[0183] The fourth driven component 80 includes a second driven pulley 801, a second weight component 802, a second driven end encoder 803, and a force application component 804. The force application component 804 includes a guide rail bracket 8041 and a weight block 8042. The guide rail bracket 8041 is disposed on the base 10 and has a guide rail in the vertical direction.

[0184] The second driven pulley 801 is used to wind one end of the rope 40 to be tested;

[0185] The active pulley 201 is also used to wind the other end of the rope 40 to be tested;

[0186] The second weight assembly 802 is disposed on the second driven rope pulley 801, and the second weight assembly 802 is used to provide load;

[0187] The second driven end encoder 803 is used to read the third rotation angle of the rope 40 under test;

[0188] The weight block 8042 is used for free-fall motion along the guide rail to impact the rope 40 under test.

[0189] In one or more embodiments, a rope testing device is described. As described above, the rope testing device can be used to detect the impact force of the rope 40 to be tested. Based on this, the rope testing device also needs to be provided with a rope pulley assembly 50 and a fourth driven assembly 80.

[0190] Specifically, for clarity, please refer to [link / reference]. Figure 14 As shown in the figure, a groove is provided on the base 10, into which the fourth driven component 80 can be inserted and then fixed to the base 10. This achieves both the effect of fixing the component and allows the user to easily adjust the position of the component on the base 10.

[0191] The test rope 40 is wound around the driving rope pulley 201 and the second driven rope pulley 801. It is understood that the middle portion of the test rope 40 may also be wound around the pulley assembly 50; this is not limited here. The driving rope pulley 201 is equipped with a driving end encoder 203, capable of reading the first rotation angle of the test rope 40. The second driven rope pulley 801 is equipped with a second driven end encoder 803, capable of reading the third rotation angle of the test rope 40.

[0192] Since the test involves impact force under normal operating conditions, a load still needs to be placed at the end. Specifically, a second weight assembly 802 is placed on the second driven pulley 801 to provide the load. The second weight assembly 802 includes a weight support frame and a weight block. A support rod is provided on the weight support frame, and the weight block can be fitted onto one end of the support rod.

[0193] The force-applying component 804 includes a guide rail bracket 8041 and a weight block 8042, with the guide rail bracket 8041 fixed to the base 10. The guide rail bracket 8041 has guide rails on both sides in the vertical direction, and the weight block 8042 has protrusions on both sides. Inserting the protrusions of the weight block 8042 into the guide rails of the guide rail bracket 8041 forms a force-applying component 804. Based on this, raising the weight block 8042 to the top of the guide rail and then releasing it allows the weight block 8042 to move freely along the guide rail and fall, thus applying an impact force to the rope 40 under test.

[0194] After the components are installed and the rope tension is adjusted, the drive motor 202 can be started. The drive motor 202 drives the active rope pulley 201 to rotate, thereby causing the test rope 40 to move back and forth. By counting the multiple free-fall impacts of the weight block 8042, the impact force of the test rope 40 can be measured based on the first rotation angle, the third rotation angle, and the mass of the weight block 8042.

[0195] Secondly, this application provides a rope testing device. Using this device, the impact force of the rope under test can be calculated by utilizing the impact of a weight falling freely onto the rope. Therefore, the rope testing device provided in this application can perform multiple performance tests, is not only easy to operate, but also improves testing efficiency.

[0196] Optionally, in the above Figures 3 to 16 Based on any of the corresponding embodiments, in another optional embodiment of the rope testing device provided in this application, the rope testing device further includes a fifth driven component 90;

[0197] The fifth driven component 90 includes a sliding bracket 901, a third driven pulley 902, a tension screw 903, and a force gauge 904. The sliding bracket 901 is mounted on the base 10, and the third driven pulley 902 is mounted on the sliding bracket 901. The sliding bracket 901 is connected to the force gauge 904 via the tension screw 903.

[0198] The third driven pulley 902 is used to wind one end of the rope 40 to be tested;

[0199] The active pulley 201 is also used to wind the other end of the rope 40 to be tested;

[0200] The tensioning screw 903 is used to adjust the position of the sliding bracket 901 on the base 10 to change the distance between the sliding bracket 901 and the tension gauge 904.

[0201] The tension gauge 904 is used to read the tension of the rope 40 to be tested.

[0202] In one or more embodiments, a rope testing device is described. As described above, the rope testing device can be used to detect the maximum tension of the rope 40 under test. Based on this, the rope testing device also needs to be provided with a rope pulley assembly 50 and a fifth driven assembly 90.

[0203] Specifically, for clarity, please refer to [link / reference]. Figure 15 As shown in the figure, a groove is provided on the base 10, into which the fifth driven component 90 can be inserted and then fixed to the base 10. This achieves both the effect of fixing the component and allows the user to easily adjust the position of the component on the base 10.

[0204] The test rope 40 is wound around the driving rope pulley 201 and the third driven rope pulley 902. It is understood that the middle portion of the test rope 40 can also be wound around the rope pulley assembly 50; this is not limited here. The sliding bracket 901 is mounted on the base 10. The tension of the tension screw 903 can be adjusted via the tension screw 903, thereby pulling the sliding bracket 901 towards the tension gauge 904, which records the tension of the test rope 40 in real time. When the test rope 40 breaks or undergoes plastic deformation, its maximum withstandable tension can be recorded.

[0205] Secondly, this application provides a rope testing device. Using this device, the maximum tension of the rope under test can be measured using a tension gauge. Therefore, the rope testing device provided in this application can perform multiple performance tests, is not only easy to operate, but also improves testing efficiency.

[0206] Optionally, in the above Figures 3 to 16 Based on any of the corresponding embodiments, in another optional embodiment of the rope testing device provided in this application, the rope testing device further includes a rope fixing member 1000;

[0207] The rope fastener 1000 is disposed on the base 10, and the rope fastener 1000 has a first rope groove and a second rope groove;

[0208] Both the first and second rope grooves are used to embed the rope 40 to be tested.

[0209] In one or more embodiments, a rope testing device is described. As described above, when the rope testing device is in operation, the rope to be tested 40 needs to be wound around both ends of the rope testing device. Therefore, the rope to be tested 40 may become entangled during movement. Based on this, at least one rope fixing member 1000 can be placed on the base 10.

[0210] Specifically, for clarity, please refer to [the relevant documentation / reference]. Figure 15As shown in the figure, two sets of rope grooves are fixed on both sides inside the rope fixing member 1000, and each set of rope grooves includes at least one rope groove. For example, taking the first rope groove fixed on the left side inside the rope fixing member 1000 and the second rope groove fixed on the right side inside the rope fixing member 1000 as an example, it can be seen that the rope to be tested 40 is embedded in the first rope groove and the second rope groove respectively, thereby achieving the purpose of separation.

[0211] Furthermore, this application provides a rope testing device. Using this device, the rope fixing component ensures that the rope under test does not detach from the rope groove during movement, making the movement of the rope under test more stable.

[0212] Optionally, in the above Figures 3 to 16 Based on any of the corresponding embodiments, in another optional embodiment of the rope testing device provided in this application, the rope testing device further includes a sixth driven component 1100;

[0213] The sixth driven component 1100 includes a fourth driven end bracket 1101, a fourth driven pulley 1102, a linkage mechanism 1103, a rotation mechanism 1104, a second encoder 1105, and a torque sensor 1106. The fourth driven end bracket 1101 is mounted on the base 10, and the fourth driven pulley 1102 is mounted on the fourth driven end bracket 1101. The fourth driven pulley 1102 is connected to the rotation mechanism 1104 through the linkage mechanism 1103.

[0214] The fourth driven pulley 1102 is used to wind one end of the rope 40 to be tested;

[0215] The active pulley 201 is also used to wind the other end of the rope 40 to be tested;

[0216] The drive motor 202 drives the fourth driven pulley 1102 to rotate through the test rope 40, and the fourth driven pulley 1102 drives the rotating mechanism 1104 to rotate through the linkage mechanism 1103.

[0217] Torque sensor 1106 is used to read the end output torque of rotary mechanism 1104;

[0218] The second encoder 1105 is used to read the end rotational angular velocity of the rotating mechanism 1104.

[0219] In one or more embodiments, a rope testing device is described. As described above, the rope testing device can be used to detect the motion efficiency of the rope 40 under test. Based on this, the rope testing device also needs to be provided with a rope pulley assembly 50 and a sixth driven assembly 1100.

[0220] Specifically, for clarity, please refer to [link / reference]. Figure 16As shown in the figure, a groove is provided on the base 10, into which the sixth driven component 1100 can be inserted and then fixed to the base 10. This achieves both the effect of fixing the component and allows the user to easily adjust the position of the component on the base 10.

[0221] The test rope 40 is wound around the driving rope pulley 201 and the fourth driven rope pulley 1102. It is understood that the middle portion of the test rope 40 can also be wound around the rope pulley assembly 50; this is not limited here. The fourth driven end bracket 1101 is mounted on the base 10, and the fourth driven rope pulley 1102 is mounted on the fourth driven end bracket 1101. The fourth driven rope pulley 1102 is connected to the rotating mechanism 1104 via a linkage mechanism 1103. Therefore, when the drive motor 202 operates, the test rope 40 can drive the rotating mechanism 1104 at its end to rotate, thus simulating the effect of workmanship.

[0222] A second encoder 1105 and a torque sensor 1106 are installed under the rotating mechanism 1104. The torque sensor 1106 reads the output torque at the end of the rotating mechanism 1104, and the second encoder 1105 reads the rotational angular velocity at the end of the rotating mechanism 1104. Based on this, and combined with the output power of the drive motor 202, the motion efficiency of the rope 40 under test can be tested.

[0223] Secondly, this application provides a rope testing device. Using this device, the motion of a motor drives the end link through rope transmission, simulating actual work, and the motion efficiency of the rope under test can be calculated. Therefore, the rope testing device provided in this application can perform multiple performance tests, is not only easy to operate, but also improves testing efficiency.

[0224] Based on the above introduction, the performance testing methods in this application will be described below. Please refer to [link / reference]. Figure 17 One embodiment of the performance testing method in this application includes:

[0225] 1201. When the rope to be tested is fixed to the rope testing device, the rope testing device is started in response to the test command for the rope to be tested;

[0226] In one or more embodiments, the rope to be tested can be fixed to the rope testing device first. Since the rope testing device has different performance tests, the corresponding test components can be selected according to actual needs.

[0227] Specifically, after being attached to the rope testing device, a test command can be triggered. For example, a user can trigger the test command through the rope testing device itself, such as by pressing a device switch to start the rope testing device. Alternatively, a user can trigger the test command through the performance testing interface displayed on a terminal device, such as by clicking a test control to start the rope testing device.

[0228] 1202. Obtain the operating parameters of the rope testing device, wherein the operating parameters include at least one of the following: first rotation angle, second rotation angle, third rotation angle, first angle difference, second angle difference, radius of the driving rope wheel, radius of the driven rope wheel, rope type, load value, pressure at the initial moment, pressure at the current moment, rotational angular velocity of the rotating block, mass of the rotating block, radius of the rotating block, mass of the weight block, motor speed of the drive motor, number of rotations of the drive motor, working time of the drive motor, working current of the drive motor, working voltage of the drive motor, tension at the current moment, end output torque, and end rotational angular velocity;

[0229] In one or more embodiments, the terminal device may acquire operating parameters transmitted from the rope testing device.

[0230] As can be seen from the foregoing embodiments, different working parameters are used to test different performance characteristics. Based on this, the terminal device selects the corresponding working parameters to calculate the test results of the rope to be tested.

[0231] 1203. Display the test results of the rope to be tested according to the working parameters.

[0232] In one or more embodiments, the test results for the rope under test are displayed by a terminal device.

[0233] It should be noted that in actual testing, the drive motor can be positioned differently. Besides being placed horizontally, it can also be placed vertically, so that the rope testing device is not on a single horizontal plane, thus enabling testing of the rope connection under various working conditions. For example, raising the drive motor's installation height by a certain point, causing the rope testing device to be on a different plane, and rotating the rope under test by 90 degrees, changes the transmission direction.

[0234] This application provides a performance testing method. By utilizing the working parameters obtained from a rope testing device, the method allows for the measurement of corresponding rope indicators on a single platform. This achieves diversified testing functions and stable performance, making performance testing more reliable and easier to operate.

[0235] Optionally, in the above Figure 17Based on the corresponding embodiments, in another optional embodiment provided by this application, the test results of the rope under test are displayed according to the working parameters, which may specifically include:

[0236] The creep of the rope to be tested is determined based on the first angle difference and the radius of the active rope pulley.

[0237] The endurance of the rope to be tested is determined based on the creep variable and the creep variable threshold.

[0238] This displays the creep and endurance of the rope under test.

[0239] In one or more embodiments, a method for displaying creep and endurance is described. As can be seen from the foregoing embodiments, the operating parameters may include a first rotation angle, a second rotation angle, a first angle difference, a load value, the radius of the driving sheave, and the radius of the driven sheave. Based on this, the motion efficiency of the rope under test can be determined. The first angle difference is the difference between the first rotation angle and the second rotation angle.

[0240] Specifically, for ease of understanding, please refer to Figure 18 , Figure 18 This is a schematic diagram of an interface displaying test results in an embodiment of this application. As shown in the figure, the rope to be tested is wound around a wire and a load is added to its end. Then, the drive motor drives the driven pulley at the end of the rope to rotate. After the drive motor has been running for a period of time, the first rotation angle read by the active encoder and the second rotation angle read by the driven encoder can be recorded. The creep of the rope to be tested can be calculated in the following way:

[0241] ;

[0242] ;

[0243] in, Represents a creep variable. This represents the difference in the first angle. Indicates the second rotation angle. This indicates the first rotation angle. This indicates the radius of the driving pulley (or the radius of the driven pulley). It represents pi (π).

[0244] When testing the endurance of a rope, the endurance can be measured by measuring the overall deformation of the rope after a long period of operation. For example, the rope can be stressed and operated under a specific condition, and the creep deformation can be calculated. When the creep deformation reaches the creep threshold, or the rope breaks, or plastic deformation occurs, it indicates that the rope has reached its service life. Therefore, the endurance of the rope can be determined based on the motor's operating time.

[0245] It should be noted that, Figure 18 The elements and layout shown on the interface are for illustrative purposes only and should not be construed as limiting the scope of this application.

[0246] Secondly, this application provides a method for displaying creep variability and endurance. Using this method, creep variability and endurance can be determined based on the test results from the rope testing device, thus providing users with more intuitive performance test results. At the same time, no additional parameter calculations are required from the user, thereby further improving the convenience of performance testing.

[0247] Optionally, in the above Figure 17 Based on the corresponding embodiments, in another optional embodiment provided by this application, the test results of the rope under test are displayed according to the working parameters, which may specifically include:

[0248] Determine the pressure difference based on the initial pressure and the current pressure;

[0249] The abrasion resistance of the rope to be tested is determined based on the pressure difference and the working time of the drive motor.

[0250] This displays the abrasion resistance of the rope being tested.

[0251] In one or more embodiments, a method for displaying abrasion resistance is described. As can be seen from the foregoing embodiments, the operating parameters may include the pressure at the initial moment, the pressure at the current moment, and the operating time of the drive motor, based on which the abrasion resistance of the rope under test can be determined.

[0252] Specifically, for ease of understanding, please refer to Figure 19 , Figure 19 This is another schematic diagram showing the test results in an embodiment of this application. As shown in the figure, the pressure of the rope under test can be set at the initial moment using a pressure sensor.

Figure 25As shown, for ease of explanation, only the parts related to the embodiments of this application are shown. For specific technical details not disclosed, please refer to the method section of the embodiments of this application. The terminal device can be any terminal device including mobile phones, tablets, personal digital assistants (PDAs), point-of-sale (POS) terminals, in-vehicle computers, etc. Taking a mobile phone as an example:

[0318] Figure 25 This diagram illustrates a partial structural representation of a mobile phone related to the terminal device provided in this embodiment. (Reference) Figure 25 The mobile phone includes components such as a radio frequency (RF) circuit 1410, a memory 1420, an input unit 1430, a display unit 1440, a sensor 1450, an audio circuit 1460, a wireless fidelity (WiFi) module 1470, a processor 1480, and a power supply 1490. Those skilled in the art will understand that... Figure 25 The mobile phone structure shown does not constitute a limitation on the mobile phone and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0319] The following is combined Figure 25 A detailed introduction to each component of a mobile phone:

[0320] RF circuit 1410 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink information from the base station and processes it with processor 1480; additionally, it transmits uplink data to the base station. Typically, RF circuit 1410 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier (LNA), a duplexer, etc. Furthermore, RF circuit 1410 can also communicate wirelessly with networks and other devices. The aforementioned wireless communication can use any communication standard or protocol, including but not limited to Global System for Mobile communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), etc.

[0321] The memory 1420 can be used to store software programs and modules. The processor 1480 executes various mobile phone functions and data processing by running the software programs and modules stored in the memory 1420. The memory 1420 may mainly include a program storage area and a data storage area. The program storage area may store the operating system, applications required for at least one function (such as sound playback function, image playback function, etc.), etc.; the data storage area may store data created according to the use of the mobile phone (such as audio data, phonebook, etc.). In addition, the memory 1420 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0322] The input unit 1430 can be used to receive input numerical or character information, and to generate key signal inputs related to user settings and function control of the mobile phone. Specifically, the input unit 1430 may include a touch panel 1431 and other input devices 1432. The touch panel 1431, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near the touch panel 1431), and drive the corresponding connected devices according to a pre-set program. Optionally, the touch panel 1431 may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to the processor 1480, and can also receive and execute commands sent by the processor 1480. In addition, the touch panel 1431 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1431, the input unit 1430 may also include other input devices 1432. Specifically, other input devices 1432 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc.

[0323] The display unit 1440 can be used to display information input by the user or information provided to the user, as well as various menus of the mobile phone. The display unit 1440 may include a display panel 1441, which may optionally be configured as a Liquid Crystal Display (LCD), Organic Light-Emitting Diode (OLED), or similar display panel. Further, a touch panel 1431 may cover the display panel 1441. When the touch panel 1431 detects a touch operation on or near it, it transmits the information to the processor 1480 to determine the type of touch event. Subsequently, the processor 1480 provides corresponding visual output on the display panel 1441 based on the type of touch event. Although in Figure 25 In this embodiment, the touch panel 1431 and the display panel 1441 are two separate components to realize the input and output functions of the mobile phone. However, in some embodiments, the touch panel 1431 and the display panel 1441 can be integrated to realize the input and output functions of the mobile phone.

[0324] The mobile phone may also include at least one sensor 1450, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor. The ambient light sensor can adjust the brightness of the display panel 1441 according to the ambient light level, and the proximity sensor can turn off the display panel 1441 and / or the backlight when the phone is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition-related functions (such as pedometer, taps), etc. Other sensors that may be configured in the mobile phone, such as gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0325] Audio circuit 1460, speaker 1461, and microphone 1462 provide an audio interface between the user and the mobile phone. Audio circuit 1460 converts received audio data into electrical signals and transmits them to speaker 1461, where speaker 1461 converts them into sound signals for output. On the other hand, microphone 1462 converts collected sound signals into electrical signals, which are received by audio circuit 1460, converted into audio data, and then processed by processor 1480 before being transmitted via RF circuit 1410 to, for example, another mobile phone, or the audio data can be output to memory 1420 for further processing.

[0326] WiFi is a short-range wireless transmission technology. Mobile phones, through the WiFi module 1470, can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 25 WiFi module 1470 is shown, but it is understood that it is not an essential component of a mobile phone and can be omitted as needed without changing the essence of the invention.

[0327] The processor 1480 is the control center of the mobile phone, connecting various parts of the phone through various interfaces and lines. It executes various functions and processes data by running or executing software programs and / or modules stored in the memory 1420 and calling data stored in the memory 1420. Optionally, the processor 1480 may include one or more processing units; optionally, the processor 1480 may integrate an application processor and a modem processor, wherein the application processor mainly handles the operating system, user interface, and applications, and the modem processor mainly handles wireless communication. It is understood that the aforementioned modem processor may also not be integrated into the processor 1480.

[0328] The phone also includes a power supply 1490 (such as a battery) that supplies power to various components. Optionally, the power supply can be logically connected to the processor 1480 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0329] Although not shown, mobile phones may also include a camera, Bluetooth module, etc., which will not be described in detail here.

[0330] The steps performed by the terminal device in the above embodiments can be based on this Figure 25 The terminal device structure is shown.
