Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, and in particular relates to an insulator tension testing device. Background Technology

[0002] Insulators, as key components in power systems, serve a dual function in transmission lines: providing reliable mechanical support for conductors and ensuring sufficient electrical insulation performance. Under actual operating conditions, insulators must withstand various mechanical stresses over extended periods, including conductor tension, wind loads, icing loads, and dynamic impacts from extreme weather. To ensure that insulators meet design requirements during their service life and to prevent power system failures due to insufficient mechanical strength, rigorous tensile testing of their mechanical properties is mandatory before they leave the factory.

[0003] Currently, the industry commonly uses tensile testing methods that involve mounting insulator samples on a tensile testing machine and applying continuous force to the insulator at a constant loading rate until it fails. However, the entire tensile testing process is highly dependent on manual operation, including sample clamping, positioning, and removal after testing. This manual operation method not only severely restricts the overall testing efficiency of insulators and significantly increases labor costs, but also poses certain safety hazards because operators need to be in close contact with samples under high load conditions.

[0004] Therefore, there is an urgent need for an insulator tension testing device to solve the above problems. Utility Model Content

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This invention provides an insulator tensile testing device. An insulator is placed on a feeding conveyor belt, which, during its operation, moves the insulator towards a movable seat. When the insulator reaches one end of the feeding conveyor belt near the movable seat, it is moved onto the movable seat. Subsequently, a second drive assembly drives the movable seat to move the insulator to a clamping seat. The clamping seat restricts the insulator's movement, and the tensile test piece clamps the insulator and moves upward under the drive of the first drive assembly. At this point, one end of the insulator is limited by the clamping seat and cannot move, while the other end can be tested for tensile strength. The test piece moves upwards, stretching the insulator and thus achieving the purpose of tensile force testing. After the test is completed, the clamping seat and tensile test piece release their constraints on the insulator, and the moving seat moves along the conveyor direction towards the discharge conveyor belt, allowing the tested insulator to automatically move to the discharge conveyor belt. Finally, the insulator automatically moves to the next process under the drive of the discharge conveyor belt, thus realizing automatic loading and unloading of insulators and automatic tensile force testing. This eliminates the need for manual handling of insulators, significantly improving the efficiency of tensile force testing and reducing labor costs. Furthermore, during the tensile force test, the two ends of the insulator are constrained by the clamping seat and tensile test piece, which helps improve the stability of the insulator under tension and enhances the safety of the tensile force testing process.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1 to 4As shown, this embodiment provides an insulator tension testing device, which realizes automated testing of the tension of insulator 100, significantly improves the efficiency of insulator 100 tension testing, reduces the labor cost of insulator 100 tension testing, and also helps to eliminate safety hazards in the tension testing process.

[0044] See Figure 1 and Figure 2 The insulator tensile testing device includes a bracket 1, a first drive assembly 2, a tensile test piece 3, a clamping seat 4, a feeding conveyor belt 5, a discharging conveyor belt 6, a second drive assembly 7, and a moving seat 8. The first drive assembly 2 and the tensile test piece 3 are both mounted on the bracket 1. The output end of the first drive assembly 2 is connected to the tensile test piece 3, used to drive the tensile test piece 3 along the vertical direction. Figure 1 The tensile test piece 3 can clamp and stretch the insulator 100 by moving in the Z direction. The clamping seat 4 is disposed on the bracket 1 and located below the tensile test piece 3, and is configured to limit the insulator 100 to be located below the tensile test piece 3. The feeding conveyor belt 5 and the discharging conveyor belt 6 are both tractably disposed on the bracket 1 and are both along the conveying direction. Figure 1 Extending in the X direction, the feeding conveyor belt 5 and the discharging conveyor belt 6 are respectively located at both ends of the tensile test piece 3 along the conveying direction; the movable seat 8 is located between the feeding conveyor belt 5 and the discharging conveyor belt 6, and the second drive assembly 7 is set on the bracket 1 and connected to the movable seat 8, for driving the movable seat 8 to move the insulator 100 along the conveying direction between the feeding conveyor belt 5, the clamping seat 4 and the discharging conveyor belt 6.

[0045] The insulator tensile testing device provided in this embodiment places the insulator 100 on the feeding conveyor belt 5. During the transmission of the feeding conveyor belt, the insulator 100 located on it can be driven to move towards the moving seat 8. When the insulator 100 moves to one end of the feeding conveyor belt 5 close to the moving seat 8, the insulator 100 will be moved from the feeding conveyor belt 5 to the moving seat 8. Subsequently, the second drive assembly 7 drives the moving seat 8 to move, so as to move the insulator 100 to the clamping seat 4. The clamping seat 4 will restrict the movement of the insulator 100, and the tensile test piece 3 will clamp the insulator 100 and move upward under the drive of the first drive assembly 2. At this time, one end of the insulator 100 is limited by the clamping seat 4 and cannot move, while the other end can be tested for tensile strength. The test piece 3 moves upward, stretching the insulator 100 and thus achieving the purpose of tensile force testing. After the test is completed, the clamping seat 4 and the tensile test piece 3 loosen their constraints on the insulator 100, and the moving seat 8 moves along the conveying direction towards the discharge conveyor belt 6, so that the tested insulator 100 can automatically move to the discharge conveyor belt. Finally, the insulator 100 can automatically move to the next process under the drive of the discharge conveyor belt 6, thereby realizing automatic loading and unloading of the insulator 100 and automatic tensile force testing. Manual handling of the insulator 100 is no longer required, significantly improving the efficiency of tensile force testing and reducing labor costs. Furthermore, during the tensile force test, both ends of the insulator 100 are constrained by the clamping seat 4 and the tensile test piece 3, which helps improve the stability of the insulator 100 under tension and enhances the safety of the tensile force testing process.

[0046] Specifically, the insulator tension detection device further includes a driving wheel, a driven wheel, and a first rotary drive component. The feeding conveyor belt 5 is wound around the driving wheel and the driven wheel, with one of the driving wheel and the driven wheel located at the end of the feeding conveyor belt near the clamping seat 4. The output end of the first rotary drive component is connected to the driving wheel and is used to drive the driving wheel to drive the feeding conveyor belt 5. The technical solution for driving the discharging conveyor belt 6 in this embodiment is the same as the technical solution for driving the feeding conveyor belt 5, and will not be described again here.

[0047] For example, the first rotary drive is a motor.

[0048] In an optional embodiment, see [link to relevant documentation] Figure 1 and Figure 2 The insulator tension testing device also includes a first linear drive component 91 and a feed blocking component 92. The feed blocking component 92 is located between the movable seat 8 and the feed conveyor belt 5. The first linear drive component 91 is mounted on the bracket 1 and connected to the feed blocking component 92, and is used to drive the feed blocking component 92 along the blocking direction. Figure 2The feed blocking member 92 moves in the Y direction. It has a feed blocking position above the feed conveyor belt 5 and a feeding position on one side of the feed conveyor belt 5 along the blocking direction. When in the feed blocking position, the feed blocking member 92 can contact the insulator 100 that has moved to the end of the feed conveyor belt 5 near the moving seat 8 to block the movement of the insulator 100. The blocking direction is set at an angle to the conveying direction. When multiple insulators 100 are conveyed on the feed conveyor belt 5 at the same time, this setting can ensure that only one insulator 100 can move from the feed conveyor belt 5 to the moving seat 8 at a time, avoiding the accumulation of insulators 100 on the moving seat 8 and affecting the smooth progress of tensile testing.

[0049] See Figure 1 and Figure 2 The insulator 100 is fixed on the mounting plate 200. The mounting plate 200 moves together with the insulator 100 between the feeding conveyor belt 5, the moving seat 8, and the discharging conveyor belt 6 to ensure the stability of the insulator 100 on these belts. In this embodiment, the feeding blocking member 92 is provided with a blocking groove. When the feeding blocking position is reached, the mounting plate 200 can enter the blocking groove and contact the groove wall to restrict the movement of the insulator 100.

[0050] Specifically, the mounting plate 200 has a rectangular cross-sectional shape, and the feed blocking component 92 adopts a right-angle blocking block. The blocking groove is the inner angle of the right-angle blocking block. When the feed blocking position is reached, the right-angle blocking block moves above the feed conveyor belt, and its two right-angled surfaces can respectively fit with the two sides of the rectangular mounting plate 200, which helps to improve the stability of the movement of the blocking insulator 100.

[0051] For example, the first linear drive 91 is a cylinder.

[0052] In this embodiment, a first sensor is provided between the clamping seat 4 and the feeding conveyor belt 5. The first sensor is electrically connected to the first linear drive member 91 and is used to identify the insulator 100 that has moved to the end of the feeding conveyor belt near the moving seat 8. When there is an insulator 100 on the moving seat 8 and the first sensor identifies that there is an insulator 100 at the end of the feeding conveyor belt near the moving seat 8, the first linear drive member 91 will drive the feeding blocking member 92 to move from the feeding position to the feeding blocking position to avoid the insulator 100 from accumulating at the moving seat 8.

[0053] In another alternative embodiment, see [link to relevant documentation]. Figure 1 and Figure 2The insulator tension detection device also includes a second linear drive 93 and a discharge blocking component 94. The discharge blocking component 94 is located between the movable seat 8 and the discharge conveyor belt 6. The second linear drive 93 is mounted on the bracket 1 and connected to the discharge blocking component 94, and is used to drive the discharge blocking component 94 to move along the blocking direction. The discharge blocking component 94 has a discharge blocking position above the discharge conveyor belt 6 and a discharge position on one side of the discharge conveyor belt 6 along the blocking direction. In the discharge blocking position, the discharge blocking component 94 can contact the insulator 100 that has moved to the end of the discharge conveyor belt 6 near the movable seat 8 to block the movement of the insulator 100. The blocking direction is set at an angle to the conveying direction. When multiple insulators 100 are conveyed simultaneously on the bracket 1, this arrangement can control the speed at which multiple insulators 100 are discharged to the discharge conveyor belt 6, i.e., the next process, avoiding overload of downstream equipment or material accumulation due to excessive flow.

[0054] In this embodiment, see Figure 2 The blocking direction, conveying direction and vertical direction are perpendicular to each other. The structure of the discharge blocking component 94 is the same as that of the feed blocking component 92, and will not be described again here.

[0055] For example, the second linear drive 93 is a cylinder.

[0056] In this embodiment, a second sensor is installed on the discharge conveyor belt 6. The second sensor is electrically connected to the second linear drive 93 and is used to identify the number of insulators 100 on the discharge conveyor belt. When the second sensor detects that insulators 100 are piled up on the discharge conveyor belt, the second linear drive 93 drives the discharge blocking member 94 to move from the discharge position to the discharge blocking position, so as to adjust the speed at which the insulators 100 are conveyed to the discharge conveyor belt 6.

[0057] In another alternative embodiment, see [link to relevant documentation]. Figure 2 The insulator tension detection device includes both a first linear drive component 91 and a feed blocking component 92, as well as a second linear drive component 93 and a discharge blocking component 94.

[0058] Optionally, see Figure 1 , Figure 3 and Figure 4The movable seat 8 includes a seat body 81, a second rotary drive member 82, and a clamping member 83. The clamping member 83 is configured to clamp the insulator 100. The second rotary drive member 82 is disposed on the seat body 81 and connected to the clamping member 83, and is used to drive the clamping member 83 to rotate in the vertical direction. When the insulator 100 moves to one end of the feeding conveyor belt 5 near the moving seat 8, the gripper 83 is controlled to grab the insulator 100 on the feeding conveyor belt 5, thus enabling the insulator 100 to move from the feeding conveyor belt 5 to the moving seat 8. Then, the second rotary drive 82 is controlled to drive the gripper 83 to rotate, which can move the gripped insulator 100 from the side of the seat 81 away from the clamping seat 4 to the side of the seat 81 facing the clamping seat 4, so that the insulator 100 can move to the clamping seat 4. After the tension of the insulator 100 is detected, the second drive assembly 7 is controlled to directly drive the moving seat 8 to move directly towards the discharge conveyor belt 6, without having to drive the gripper 83 to rotate the insulator 100. The operation is convenient and quick, and it also achieves the conveying of the insulator 100 from the feeding conveyor belt 5 to the moving seat 8 and from the moving seat 8 to the discharge conveyor belt 6.

[0059] For example, the second rotary drive 82 is a motor.

[0060] See Figure 2 and Figure 4 The feeding conveyor belt 5, the moving seat 8, the clamping seat 4 and the discharging conveyor belt 6 are coaxial, and the second rotary drive 82 drives the clamping part 83 to rotate 180 degrees.

[0061] In this embodiment, see Figure 1 and Figure 4 The gripper 83 includes a drive unit 831, a first claw 832, and a second claw 833. The first claw 832 and the second claw 833 are spaced apart. The output end of the drive unit 831 is connected to the first claw 832 and the second claw 833 to drive the first claw 832 and the second claw 833 to move closer or further apart, thereby adjusting the distance between the first claw 832 and the second claw 833. When the distance between the first claw 832 and the second claw 833 decreases, the first claw 832 and the second claw 833 can gradually approach the insulator 100 to grip the insulator 100; when the distance between the first claw 832 and the second claw 833 increases, the first claw 832 and the second claw 833 can relax their gripping effect on the insulator 100, allowing the insulator 100 to move toward the discharge conveyor belt 6.

[0062] For example, the gripper 83 is a pneumatic gripper, the drive unit 831 is a cylinder for the pneumatic gripper, and the first gripper 832 and the second gripper 833 are grippers for the pneumatic gripper.

[0063] For example, see Figure 1 and Figure 4The insulator 100 has a circular cross-sectional shape, and the first claw 832 and the second claw 833 both have arc-shaped cross-sections, so that the first claw 832 and the second claw 833 can stably grip the part where the silicone at the bottom of the insulator 100 connects to the mounting plate 200.

[0064] Optionally, see Figure 1 and Figure 4 The second drive assembly 7 includes a third rotary drive member 71, a drive gear 72, and a driven rack 73. The drive gear 72 meshes with the driven rack 73, which extends along the conveying direction. The movable seat 8 is connected to the drive gear 72. The output end of the third rotary drive member 71 is connected to the drive gear 72 to drive the drive gear 72 to rotate. The drive gear 72 drives the movable seat 8 to move along the extension direction of the driven rack 73, thereby achieving the purpose of moving the movable seat 8 along the conveying direction. By driving the movable seat 8 to move through the meshing of the drive gear 72 and the driven rack 73, the accuracy and stability of driving the movable seat 8 can be improved, ensuring the reliability of the insulator 100 when it moves with the movable seat 8.

[0065] For example, the third rotary drive 71 is a motor, which enables the movable seat 8 to reciprocate along the driven rack 73, thereby realizing the reciprocating movement of the movable seat 8 between the feed conveyor belt 5 and the discharge conveyor belt 6.

[0066] Optionally, see Figure 1 and Figure 3 The first drive assembly 2 includes a fourth rotary drive component 21 and a lead screw 22. The lead screw 22 extends vertically, and the tensile test piece 3 is threadedly connected to the lead screw 22. The fourth rotary drive component 21 is mounted on the bracket 1 and connected to the lead screw 22, and is used to drive the lead screw 22 to rotate around its axial direction. The lead screw 22 can drive the tensile test piece 3 to move vertically, so as to achieve the purpose of automatic tensile testing of the insulator 100. The threaded connection between the lead screw 22 and the tensile test piece 3 can convert the rotational motion of the lead screw 22 into the linear motion of the tensile test piece 3. It not only has the characteristics of high precision, high rigidity and self-locking characteristics, but also allows the tensile force and tension time of the tensile test piece 3 on the insulator 100 to be precisely adjusted, and also allows the tensile test piece 3 to reciprocate in the vertical direction.

[0067] Specifically, when the tensile test piece 3 moves upward, it can stretch the insulator 100 to test the tensile force of the insulator 100; when the tensile test piece 3 moves downward, it can restore the deformation of the insulator 100, making it easier to proceed to the next process.

[0068] For example, the fourth rotary drive 21 is a motor that can drive the lead screw 22 to rotate clockwise and counterclockwise so that the tensile test piece 3 can move back and forth in the vertical direction.

[0069] In this embodiment, see Figure 3 There are two lead screws 22, which are respectively located on both sides of the tensile test piece 3 along the first direction. The first drive assembly 2 also includes two first connecting shafts 23, two second connecting shafts 24, and two steering gears 25. The two lead screws 22 correspond one-to-one with the two steering gears 25, and the two steering gears 25 correspond one-to-one with the two first connecting shafts 23. The first connecting shafts 23 and the second connecting shafts 24 both extend along the first direction. One end of the first connecting shaft 23 is connected to the corresponding steering gear 25, and the other end is connected to the output end of the fourth rotary drive 21. The steering gear 25 is located at the top of the corresponding lead screw 22. The two ends of the second connecting shaft 24 are threadedly connected to the two lead screws 22 respectively. The tensile test piece 3 is installed on the second connecting shaft 24. The fourth rotary drive 21 can drive the two first connecting shafts 23 to rotate simultaneously. The first connecting shafts 23 drive the lead screws 22 to rotate through the steering gears 25, so that the second connecting shafts 24 drive the tensile test piece 3 to move vertically. This configuration allows the rotation of the two first connecting shafts 23 to be driven by a fourth rotary drive 21, thereby ensuring that the two lead screws 22 rotate at the same angle and that both ends of the second connecting shaft 24 can move synchronously in the vertical direction. This makes the movement of the tensile test piece 3 more stable and improves the efficiency and quality of tensile testing.

[0070] Among them, see Figure 3 First direction ( Figure 3 In one embodiment, the Y direction is perpendicular to the vertical direction and perpendicular to the test direction; in another embodiment, the first direction is perpendicular to the vertical direction and is set at an angle to or parallel to the test direction.

[0071] For example, the steering gear 25 employs a coupling.

[0072] In other embodiments, the output end of the fourth rotary drive 21 is directly connected to the lead screw 22.

[0073] Optionally, see Figure 2 The support 1 is provided with a track 11 extending along the conveying direction, and the movable seat 8 is disposed on the track 11 and slides in cooperation with the track 11 to improve the stability of the movable seat 8 moving on the support 1.

[0074] Specifically, the movable seat 8 is provided with a sliding groove, and the track 11 is provided with a sliding part, which is located in the sliding groove and slides in cooperation with the sliding groove.

[0075] In this embodiment, see Figure 2 Two tracks 11 are provided, located on both sides of the movable seat 8, which can further improve the stability of the movable seat 8 moving on the support 1.

[0076] Optionally, see Figure 1 and Figure 3The tensile test piece 3 includes a mounting base 31, a first clamping part 32, and a second clamping part 33. The first clamping part 32 and the second clamping part 33 are spaced apart on the mounting base 31 along a second direction, and the distance between the first clamping part 32 and the second clamping part 33 is adjustable. This arrangement allows the clamping force of the tensile test piece 3 on the insulator 100 to be adjusted by adjusting the distance between the first clamping part 32 and the second clamping part 33, thereby ensuring the stability of the clamping of the insulator 100 by the tensile test piece 3 and enabling the tensile test piece 3 to clamp insulators 100 of different specifications.

[0077] In this embodiment, see Figure 3 Second direction ( Figure 3 In one embodiment, the Y direction is perpendicular to the vertical direction and perpendicular to the test direction; in another embodiment, the second direction is perpendicular to the vertical direction and is set at an angle to or parallel to the test direction.

[0078] For example, the tensile test piece 3 uses a pneumatic gripper, the first gripping part 32 and the second gripping part 33 are the grippers of the pneumatic gripper, and the distance between the first gripping part 32 and the second gripping part 33 is adjusted by a cylinder.

[0079] Optionally, see Figure 1 and Figure 3 The clamping seat 4 includes a clamping direction ( Figure 3 A first clamping member 41 and a second clamping member 42 are movable in both directions (Y-direction), and are respectively disposed on both sides of the movable base 8 along the clamping direction, wherein the clamping direction is set at an angle to the conveying direction. This arrangement allows the distance between the first clamping member 41 and the second clamping member 42 and the insulator 100 located on the movable base 8 to be adjusted by adjusting the position of the first clamping member 41 and the second clamping member 42 along the clamping direction. When the first clamping member 41 and the second clamping member 42 approach each other and contact and clamp the insulator 100 on the movable base 8, clamping of the insulator 100 can be achieved.

[0080] In this embodiment, see Figure 3 The blocking direction, the first direction, the second direction, and the clamping direction are parallel to each other, and all are... Figure 3 in the Y direction.

[0081] Specifically, see Figure 3 The clamping base 4 also includes a third linear drive 43 and a fourth linear drive 44.

[0082] In this embodiment, see Figure 1 and Figure 3The first clamping member 41 and the second clamping member 42 are both provided with semi-circular grooves 45, and the openings of the two grooves 45 are opposite each other. When the first clamping member 41 and the second clamping member 42 approach each other, the two grooves 45 are joined together to form a circular limiting hole. At this time, the insulator 100 can be located in the circular limiting hole and abut against the hole wall of the circular limiting hole, that is, the groove wall of the groove 45.

[0083] Optionally, the insulator tension testing device further includes a control module mounted on the bracket 1. The control module is used to control the transmission of the feeding conveyor belt 5, the transmission of the discharging conveyor belt 6, the opening and closing of the first drive component 2, and the opening and closing of the second drive component 7, so as to realize the automatic control of each component of the insulator 100 tension testing device.

[0084] Specifically, the control module is electrically connected to the first sensor, the second sensor, the first linear drive 91, the second linear drive 93, the third linear drive 43, the fourth linear drive 44, the first rotary drive, the second rotary drive 82, the third rotary drive 71, and the fourth rotary drive 21, so that each step of the movement of the insulator 100 on the bracket 1 and the tension detection can be controlled independently.

[0085] In this embodiment, a third sensor is provided on the tensile test piece 3. The third sensor is electrically connected to the control module and is used to measure the tensile force on the insulator 100 so that the staff can quickly and intuitively obtain the tensile force on the insulator 100.

[0086] The process of using the insulator tension testing device provided in this embodiment to test the tension of insulator 100 is as follows:

[0087] S1. Place the insulator 100 on the feeding conveyor belt 5. The feeding conveyor belt 5 drives the insulator 100 to move towards the moving seat 8 along the conveying direction. When the insulator 100 moves to one end of the feeding conveyor belt 5 close to the moving seat 8, control the first linear drive 91 to drive the feeding blocking part to move to the feeding blocking position. The mounting plate 200 below the insulator 100 contacts the feeding blocking part 92 so that the clamping part 83 can stably clamp the insulator 100 on the feeding conveyor belt 5.

[0088] S2. After the third rotary drive 71 drives the movable seat 8 to move to the feeding conveyor belt 5 via the drive gear 72 and the driven rack 73, the second rotary drive 82 is controlled to drive the gripper 83 to rotate, so that the first claw 832 and the second claw 833 move to the side facing the feeding conveyor belt 5; then, the drive unit 831 is controlled to drive the first claw 832 and the second claw 833 to move towards each other to grip the insulator 100 located at the end of the feeding conveyor belt 5 near the movable seat 8; finally, the first linear drive 91 is controlled to drive the feeding blocking part to the feeding position.

[0089] S3. Control the second rotary drive 82 to drive the gripper 83 to rotate, so that the first claw 832 and the second claw 833 drive the insulator 100 to move to the side away from the feed conveyor belt 5; then, control the third rotary drive 71 to drive the moving seat 8 to the gripper seat 4 through the drive gear 72 and the driven rack 73.

[0090] S4. Control the third linear drive 43 to drive the first clamping member 41 to move towards the moving seat 8, and control the fourth linear drive 44 to drive the second clamping member 42 to move towards the moving seat 8 until the groove walls 45 on the first clamping member 41 and the second clamping member 42 are in contact with the moving seat 8. Then, control the fourth rotary drive 21 to drive the lead screw 22 to move the tensile test member 3 downward. After the tensile test member 3 moves above the insulator 100, drive the first clamping part 32 and the second clamping part 33 to move towards each other to clamp the top of the insulator 100.

[0091] S5. Control the fourth rotary drive component 21 to drive the lead screw 22 to move the tensile test component 3 upward, and the insulator 100 is stretched in order to detect the tensile force of the insulator 100.

[0092] S6. After the tensile test of insulator 100 is completed, the first clamping part 32 and the second clamping part 33 are driven to move away from each other, and the first clamping member 41 and the second clamping member 42 are driven to move away from each other, so as to release the clamping on insulator 100. Then, the third rotary drive member 71 is controlled to drive the moving seat 8 to move towards the discharge conveyor belt 6. When the insulator 100 moves to the discharge conveyor belt 6, the drive member 831 is controlled to drive the first claw 832 and the second claw 833 to move in the horizontal direction to release the clamping on insulator 100. The insulator 100 moves to the next process under the drive of the discharge conveyor belt 6.

Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
