Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0019] A device for detecting the tensile strength of an insulator disclosed in the present invention is mainly applied to scenarios where the detection results of the tensile strength of the insulator will have large errors due to differences in actual use states.

[0020] Refer to Figures 1-10 , a device for detecting the tensile strength of an insulator, comprising: A detection box 1, a control box 2 is fixedly connected to the front side of the detection box 1, and the control box 2 is used to start and stop the components in the detection box 1 and analyze and issue a report; A fixed table 3, fixedly connected to one end of the detection box 1 away from the control box 2; A movable table 4, movably connected to the detection box 1, located between the fixed table 3 and the control box 2; Two clamping assemblies 5 are respectively arranged on the opposite sides of the fixed table 3 and the movable table 4 for clamping the insulator, and anti-disengagement assemblies 8 are arranged on both clamping assemblies 5 for detecting the stability of the insulator after clamping; A multi-position simulation module 6 is located between the fixed table 3 and one clamping assembly 5 for simulating the actual installation environment of the insulator; An adaptive detection module 7 is located between the movable table 4 and the other clamping assembly 5 for angle adjustment and data feedback during the tensile strength detection process of the insulator.

[0021] The device can provide two different installation environments to achieve the effect of simulating the actual use state of the insulator. Under this state, the detection can effectively obtain the tensile strength of the insulator during actual use, thus ensuring the accuracy of the tensile strength detection result; the clamping assembly 5 can provide clamping for the insulator during detection, and the anti-disengagement assembly 8 can ensure the position of the insulator after clamping and fixing, avoiding the insulator falling off due to untimely discovery.

[0022] Refer to Figure 3 , Figure 4 and Figure 5 , in a preferred embodiment, the clamping assembly 5 includes: A socket 501, a front seat 502 is fixedly connected to the front end of the socket 501, an installation hole is opened on the front seat 502, and a clamping hydraulic cylinder 509 is fixedly connected to the inside of the installation hole; A driving frame 503 is slidably connected to the inside of the socket 501, the telescopic end of the clamping hydraulic cylinder 509 is fixedly connected to the driving frame 503, and three movable position connecting blocks 508 are movably connected to the driving frame 503.

[0023] In the present invention, the clamping assembly 5 further includes: Three clamping claws 504, the front ends of the three clamping claws 504 are fixedly connected with pressing heads 505, the three clamping claws 504 are respectively provided with flipping holes 506 and pulling holes 507, short shafts are respectively arranged inside the flipping holes 506, the clamping claws 504 and the front seat 502 are rotationally connected through bearings, and connecting shafts are respectively arranged on the three movable position connecting blocks 508, and the connecting shafts are respectively rotationally connected inside the pulling holes 507 through bearings.

[0024] Specifically, place the top of the insulator at the position of the clamping claws 504, start the clamping hydraulic cylinder 509 to contract to drive the pulling frame 503 to approach the front seat 502, the movable position connecting block 508 deflects on the pulling frame 503 and applies a thrust forward to the clamping claws 504, and the three clamping claws 504 flip on the front seat 502 and approach each other to clamp the top of the insulator. In a specific application scenario, the clamping assembly 5 is applicable to the clamping and fixing link during the insulator detection, that is, the clamping assembly 5 uses three clamping claws 504 to clamp and fix from both ends of the insulator, so as to meet the subsequent tensile test operation. The three-claw fixing method can effectively ensure the stability of the insulator clamping and fixing, and at the same time, this fixing method can meet the clamping and fixing requirements of insulators of different specifications, improving the application range of the device.

A locking bolt 805, rotatably connected through the inner wall thread in the threaded hole of the locking box 802, the lower end of the locking bolt 805 contacts the cross frame 804 to fix the position of the cross frame 804.

[0026] Specifically, after the insulator is clamped, loosen the locking bolt 805, move the cross frame 804 so that the contact sensor 803 contacts the top of the insulator, and then tighten the locking bolt 805, and the control box 2 receives the status information of the contact sensor 803. In a specific application scenario, the anti - detachment component 8 is applicable to the locking link of the insulator's position after fixed installation. That is, the anti - detachment component 8 uses the contact - type sensor 803 to directly contact the top of the fixed insulator to determine its position information, avoiding the loosening of the clamping position during the subsequent pulling detection that cannot be detected in time, resulting in the insulator falling off from the clamping component 5 and causing damage to the device due to impact.

[0027] Referring to Figure 8 、 Figure 9 and Figure 10 In a preferred embodiment, the multi - bit analog module 6 includes: A rotating table 601, rotatably connected to the fixed table 3. A rotating motor 602 is fixedly connected to the fixed table 3. The output shaft of the rotating motor 602 is connected to a rotating shaft through a coupling. The other end of the rotating shaft passes through the fixed table 3 and is fixedly connected to the rotating table 601. A chute is provided on the rotating table 601, and the rotation of the rotating table 601 is used to adjust the pulling angle of the insulator during detection. A lifting seat 603, slidably connected to the chute of the rotating table 601. A threaded hole is provided on the lifting seat 603. A lifting motor 604 is fixedly connected to the rotating table 601. The output shaft of the lifting motor 604 is connected to an adjusting screw rod 605 through a coupling. The other end of the adjusting screw rod 605 passes through the threaded hole of the lifting seat 603. The lifting of the lifting seat 603 is used to further adjust the pulling angle of the insulator during detection.

[0028] In the present invention, the multi - bit analog module 6 further includes: An analog seat 606, located between the lifting seat 603 and the sleeve seat 501.

A locking block 609, inserted into the jack 610 and the fixing hole 611, is used to fix the connection state between the analog seat 606 and the lifting seat 603. The analog seat 606 is used to simulate the actual use environment of the insulator. The analog seat 606 and the lifting seat 603 are fixed by the locking block 609 for conventional pulling detection, and the analog seat 606 and the lifting seat 603 are fixed by the steel wire rope 608 for pulling detection in the simulated actual state.

[0029] Specifically, the tensile strength detection is divided into conventional detection and detection under simulated conditions; Conventional detection: The plug block 607 is inserted into the jack 610 and the fixing hole 611, and the lifting seat 603 and the analog seat 606 are assembled into one body. At this time, the tensile strength of the insulator in the horizontal state is detected. Detection in simulation state: Pull out the locking block 609 so that the insertion block 607 disengages from the lifting seat 603. After adjusting the device, make the steel wire rope 608 in a taut state. Then start the lifting motor 604 to drive the position adjusting screw rod 605 to rotate, change the position of the lifting seat 603, simulate the suspension state of the insulator during actual use. During the detection process, start the rotation motor 602 to drive the rotating table 601 to rotate according to requirements, and the pulling angle of the insulator changes, simulating the pulling states of the insulator at different angles during actual use. In a specific application scenario, the multi-position simulation module 6 is applicable to simulating different installation environments during the detection process of the insulator. The multi-position simulation module 6 can provide two simulation environments during the detection process (tensile strength detection under normal horizontal state and tensile strength detection under actual use environment), detect the tensile strength of the insulator in different scenarios, and effectively ensure the accuracy of the tensile strength detection result of the insulator. The position of the lifting seat 603 can be adjusted by the lifting motor 604, and the detection under different suspension amplitudes can be realized. During the detection process, the lifting seat 603 can rotate along with the rotating table 601, and the detection under different suspension angles can be realized. The combination of the two can effectively simulate the actual installation environment and further ensure the accuracy of the tensile strength detection result of the insulator.

[0031] Specifically, during the detection process, the position of the connecting ball 706 in the spherical mounting block 704 will be adjusted automatically along with the change of the pulling state, and the detected tension data will be transmitted to the control box 2 in real time through the tension sensor 703; In a specific application scenario, the adaptive detection module 7 is applicable to the detection process. That is, the adaptive detection module 7 uses the connecting ball 706 and the spherical mounting block 704 to maintain the movable connection state between the clamping assembly 5 and the movable table 4, thus ensuring the smoothness of the subsequent detection process at different pulling angles; the tension sensor 703 can real-time feedback the tension value, making the tensile strength data of the insulator more accurate.

Both of the two blanking plates 13 are in a slope shape, and a same collection bin 14 is arranged at the lower ends of the two blanking plates 13.

[0035] Specifically, during the detection, the fragments after the insulator breaks will fall on the blanking plate 13 and slide into the collection bin 14 for collection, which is convenient for subsequent cleaning.

[0036] A method for detecting the tensile strength of an insulator, using the device for detecting the tensile strength of an insulator as described above, includes the following steps: Step 1: Adjust the position of the movable table 4 according to the length of the insulator to be detected (the detection motor 10 drives the detection lead screw 11 to rotate, and the movable table 4 moves on the detection box 1).
