Description

Technical Field

[0001] This application relates to the field of insulator testing technology, and in particular to an insulation testing device for an insulating rod. Background Technology

[0002] Currently, "insulating rod" is a general term for a set of insulating tools specifically used in power systems. These tools are used for live-line work, live-line inspection, and live-line maintenance, and are primarily made of insulating tubes or rods, including end fittings. Due to the special nature of their use, the insulation performance of insulating rods must be thoroughly tested before use; otherwise, serious safety accidents may occur. Generally, the insulation performance of insulating rods is tested by manually applying electrodes to both ends of the rod and measuring whether current flows through it. If no current flows, the insulating rod is considered usable; if current flows, the rod is defective.

[0003] Regarding the aforementioned technologies, the inventors believe that manual measurement can only test one insulating rod at a time, and the measurement is time-consuming, labor-intensive, and inefficient, making it inconvenient to carry out measurement work. Summary of the Invention

[0004] To improve the problem of low measurement efficiency when measuring the insulation of insulating rods, the purpose of this application is to provide an insulating rod insulation testing device.

[0005] The insulation performance testing device for insulating rods provided in this application adopts the following technical solution:

[0006] An insulation rod insulation testing device includes a testing frame, crossbars, rod segment clamping mechanisms, rod end fixing mechanisms, and an energizing testing mechanism. Multiple crossbars are vertically arranged on the testing frame, and each crossbar is horizontally mounted on the testing frame. Multiple rod segment clamping mechanisms are arranged along the length of the crossbars. The rod end fixing mechanisms are mounted on the testing frame above the multiple crossbars and are used to fix the top ends of the insulating rods clamped on the multiple rod segment clamping mechanisms. The energizing testing mechanism is used to simultaneously contact and energize both ends of all insulating rods.

[0007] By adopting the above technical solution, when testing the insulation performance of insulating rods, multiple insulating rods can be clamped sequentially on the rod segment clamping mechanism, and then fixed in place by the rod end fixing mechanism. At this time, multiple insulating rods are simultaneously fixed on the testing frame. Moreover, the multiple crossbars can accommodate different models of insulating rods, thus improving the applicability of this application. After the insulating rods are fixed, the multiple fixed insulating rods can be tested simultaneously by the power-on testing mechanism. This setup improves the measurement efficiency when testing the insulation performance of insulating rods.

[0008] Optionally, the pole clamping mechanism includes a mounting block and a clamping ring. The mounting block is detachably mounted on the crossbar, and the clamping ring is disposed on the mounting block. The clamping ring has a clamping groove for inserting the insulating pole.

[0009] By adopting the above technical solution, when fixing the insulating rod, first place the insulating rod to be measured into the clamping groove in the clamping ring so that the outer circumference of the insulating rod is in the clamping groove; at this time, the displacement of the insulating rod in the circumferential direction is restricted, thereby making it easier to clamp the insulating rod.

[0010] Optionally, the clamping groove is filled with conductive sponge, which is used to clamp the insulating rod in the clamping groove.

[0011] By adopting the above technical solution, filling with conductive sponge can make the insulating rod clamp more stable.

[0012] Optionally, the rod end fixing mechanism includes a hanging connection assembly and a clamp connection assembly. Both the hanging connection assembly and the clamp connection assembly are installed on the top of the testing frame. The hanging connection assembly is used to connect with an insulating rod with a hook type, and the clamp connection assembly is used to connect with an insulating rod without a hook type.

[0013] By adopting the above technical solution, when an insulating rod with a hook needs to be tested, the hook on the insulating rod can be connected to the hanging connection assembly; when an insulating rod without a hook needs to be tested, the insulating rod can be clamped on the testing frame by the clamp connection assembly, thereby improving the applicability of this application.

[0014] Optionally, the hanging connection assembly includes a first top rod and an L-shaped hanging rod; the first top rod is installed on the testing frame and is aligned with the length direction of the crossbar; multiple L-shaped hanging rods are arranged along the length direction of the first top rod, and each L-shaped hanging rod corresponds one-to-one with a rod segment clamping mechanism on the crossbar.

[0015] By adopting the above technical solution, the hook end of the insulating rod with hook is directly fastened to the horizontal section of the L-shaped hanging rod. At this time, the section of the insulating rod is clamped by the clamping groove, and the rod end is fastened to the L-shaped hanging rod and will not fall down, thus achieving the fixation of the insulating rod with hook, and achieving the effect of fixing the insulating rod with hook in a more convenient way.

[0016] Optionally, the clamp-type connection assembly includes a second push rod, a mounting base, and a snap-fit ​​piece. The second push rod is disposed on the testing frame below the first push rod and above multiple crossbars. The length direction of the second push rod is consistent with that of the first push rod. Multiple mounting bases are provided along the length direction of the second push rod, and each mounting base corresponds to an L-shaped hanging rod. The snap-fit ​​piece is rotatably disposed on the mounting base. The snap-fit ​​piece has a groove for engaging with the wall of the insulating rod, and the groove is covered with a rubber layer.

[0017] By adopting the above technical solution, when it is necessary to fix an insulating rod without a hook, the snap-fit ​​piece is flipped on the mounting base so that the snap-fit ​​groove on the snap-fit ​​piece is directly above the clamping groove. Then, the insulating rod without a hook is gradually passed through from bottom to top, or the insulating rod without a hook is first deliberately lowered below the clamping groove, and then moved vertically upward so that the end of the insulating rod without a hook is locked in the rubber layer of the clamping groove, thereby achieving fixation and making it more convenient to fix the insulating rod without a hook.

[0018] Optionally, the power-on testing mechanism includes a distribution box, wires, an upper clamp, and a lower clamp; the distribution box is installed on the testing frame, and the upper clamp and the lower clamp are electrically connected to the distribution box via wires; the number of the upper clamp and the lower clamp is the same as the number of the pole segment clamping mechanism on a crossbar.

[0019] By adopting the above technical solution, the upper clamp is held at the upper end of the insulating rod and the lower clamp is held at the lower end of the insulating rod. Then, the distribution box is started, and it is observed whether there is current flowing through the insulating rod.

[0020] Optionally, the testing frame is also equipped with a quick unloading mechanism, which is used to remove all the insulating rods with hooks that are attached to multiple L-shaped hanging rods at once.

[0021] By adopting the above technical solution, the quick unloading mechanism allows the insulated rods with hooks to be quickly collected after measurement, and eliminates the need for workers to manually touch the insulated rods, thus avoiding the risk of electric shock.

[0022] Optionally, the quick unloading mechanism includes a collection box, a press-to-start assembly, a transmission assembly, and a pushing assembly; the collection box is equipped with a rubber pad and is installed on the detection frame below multiple hanging insulating rods; the press-to-start assembly is installed on the collection box; the transmission assembly and the pushing assembly are both installed on the detection frame; when the press-to-start assembly is subjected to external force, the transmission assembly transmits the compressive force to the pushing assembly, thereby simultaneously pushing all the hanging insulating rods from the L-shaped hanging rods into the collection box.

[0023] By adopting the above technical solution, the external force is used to press and activate the component. The pressure is then transmitted to the pushing component through the transmission component, which generates a horizontal thrust. This pushes the insulating rod with the hook out horizontally from the L-shaped hanging rod and the clamping groove. At this time, the insulating rod with the hook will fall directly into the collection box under the action of gravity and be stably stored under the buffering effect of the rubber pad, thereby achieving the effect of quickly unloading the insulating rod with the hook.

[0024] Optionally, the press-to-start assembly includes a foot pedal, a slider, and a first spring; a vertical groove is provided on the side wall of the collection box, the slider is installed at one end of the foot pedal and slidably disposed in the groove, and the first spring is installed between the inner wall of the groove and the slider, the first spring causing the foot pedal to always have a tendency to move vertically upward;

[0025] The pushing assembly includes a sliding rod, a sleeve, a second spring, a pull rope, and a rolling sleeve. One sleeve is horizontally positioned on each side of the multiple insulating rods attached to the testing frame. One end of the sliding rod is slidably inserted into the sleeve. The second spring is installed inside the sleeve, ensuring the sliding rod always tends to move further into the sleeve. The pull rope is positioned between two sliding rods and is horizontally taut. Multiple rolling sleeves are rotatably mounted on the pull rope.

[0026] The transmission assembly includes a first steering wheel, a second steering wheel, and a traction rope. A sliding strip hole is provided on the side wall of the sleeve, and a connecting rod extending out of the sliding strip hole is provided on the sliding rod. The first steering wheel is rotatably mounted on the detection frame, and the second steering wheel is rotatably mounted on the detection frame and located below the first steering wheel. A guide wheel is also rotatably mounted on the side wall of the collection box. One end of the traction rope is connected to the connecting rod, and the other end passes through the upper wheel surface of the first steering wheel, the lower wheel surface of the second steering wheel, and the upper wheel surface of the guide wheel in sequence before connecting to the side wall of the pedal.

[0027] By adopting the above technical solution, the worker first presses the pedal vertically downwards. The pedal causes the slider to move vertically downwards within the groove, which in turn causes the traction rope to be pulled by the downward movement of the pedal. Under the guidance of the first steering wheel, the second steering wheel, and the guide wheel, the downward movement of the pedal is ultimately converted into a pulling force on the connecting rod along the direction of the sliding strip hole. This drives the sliding rod to move into the sleeve. At this time, the pull rope between the two sliding rods moves closer to the insulating rod side. The rolling sleeve on the pull rope abuts against the side wall of the insulating rod and applies a horizontal pushing force to the insulating rod. Finally, the insulating rod is horizontally disengaged from the L-shaped hanging rod and the clamping groove and falls into the collection box under the action of gravity. This achieves a more intuitive and convenient effect of unloading the insulating rod with the hook.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. When testing the insulation performance of insulating rods, multiple insulating rods can be clamped sequentially onto a rod segment clamping mechanism, and then fixed in place by a rod end fixing mechanism. In this case, multiple insulating rods are simultaneously fixed to the testing frame. Furthermore, the multiple crossbars allow for the adaptation of different types of insulating rods, improving the applicability of this application. After the insulating rods are fixed, the multiple fixed insulating rods can be tested simultaneously via an energized testing mechanism. This setup improves the measurement efficiency when testing the insulation performance of insulating rods.

[0030] 2. When an insulating rod with a hook needs to be tested, the hook on the insulating rod can be connected to the hanging connection assembly; when an insulating rod without a hook needs to be tested, the insulating rod can be clamped onto the testing frame through the clamp connection assembly, thereby improving the applicability of this application.

[0031] 3. First, the worker presses the pedal vertically downwards. The pedal moves the slider vertically downwards within the groove, causing the traction rope to be pulled by the downward movement of the pedal. Guided by the first steering wheel, the second steering wheel, and the guide wheel, the downward movement of the pedal is ultimately converted into a pulling force on the connecting rod along the direction of the sliding strip hole. This drives the sliding rod to move into the sleeve. At this time, the pull rope between the two sliding rods moves closer to the insulating rod side. The rolling sleeve on the pull rope abuts against the side wall of the insulating rod and applies a horizontal pushing force to the insulating rod. Finally, the insulating rod is horizontally disengaged from the L-shaped hanging rod and the clamping groove, and falls into the collection box under the action of gravity. This achieves a more intuitive and convenient effect of unloading the insulating rod with the hook. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0041] An insulation rod insulation testing device, with reference to Figure 1 , 2 The system includes a testing frame 1, crossbars 2, rod segment clamping mechanisms 3, rod end fixing mechanisms 4, and an energizing testing mechanism 5. The testing frame 1 is composed of multiple horizontal tubes and multiple vertical tubes connected together, and is equipped with casters at the lower end of the testing frame 1 for easy movement. Multiple crossbars 2 are arranged along the vertical direction of the testing frame 1, i.e., the crossbars 2 are installed between two horizontal tubes, and each crossbar 2 is horizontally and parallel. Multiple rod segment clamping mechanisms 3 are installed on each crossbar 2, with equal spacing between them, and the rod segments clamped on adjacent crossbars 2 correspond one-to-one in the vertical direction. The rod end fixing mechanism 4 is installed on the testing frame 1 above the multiple crossbars 2, and is used to fix the top ends of the insulating rods clamped on the multiple rod segment clamping mechanisms 3. The energizing testing mechanism 5 is used to simultaneously contact and energize both ends of all insulating rods.

[0042] When testing the insulation performance of insulating rods, multiple insulating rods can be installed on the testing frame 1 simultaneously. During installation, the rod segment clamping mechanism 3 clamps and fixes the side wall of the insulating rod, while the rod end fixing mechanism 4 clamps and fixes the top of the insulating rod, thus achieving simultaneous clamping of multiple insulating rods. Furthermore, with multiple crossbars 2, insulating rods of different lengths can be clamped, improving the adaptability of the insulating rods. After fixing the insulating rods, the insulation performance of multiple insulating rods can be measured simultaneously through the power-on testing mechanism 5, thereby improving the measurement efficiency when testing the insulation performance of insulating rods.

[0043] Reference Figure 2 , 3 The rod segment clamping mechanism 3 includes a mounting block 31 and a clamping ring 32. The mounting block 31 is detachably mounted on the crossbar 2. In this embodiment, the mounting block 31 has a threaded hole, and the crossbar 2 also has a threaded hole, that is, the mounting block 31 and the crossbar 2 are connected by bolts; in other embodiments, a pin connection can also be used. The clamping ring 32 is set on the mounting block 31, and the clamping ring 32 has a clamping groove 321 for the insulating rod to be inserted. The clamping ring 32 is U-shaped, and the clamping groove 321 is also U-shaped, so that the insulating rod can be placed in the clamping ring 32 and the horizontal movement of the insulating rod can be limited. In order to improve the clamping effect of the clamping groove 321, when the insulating rod is in the clamping groove 321, conductive sponge is filled between the insulating rod and the clamping groove 321.

[0044] When fixing the insulating rod, first place the insulating rod to be measured into the clamping groove 321 in the clamping ring 32, so that the outer circumference of the insulating rod is within the clamping groove 321; at this time, the displacement of the insulating rod in the circumferential direction is restricted, thus making it easier to clamp the insulating rod; and filling it with conductive sponge can make the insulating rod clamped more stably.

[0045] Combination Figure 2 , 4 The rod end fixing mechanism 4 includes a hanging connection assembly 41 and a clamping connection assembly 42. Both the hanging connection assembly 41 and the clamping connection assembly 42 are installed on the top of the testing frame 1. The hanging connection assembly 41 is used to connect with the insulating rod with a hook type, and the clamping connection assembly 42 is used to connect with the insulating rod without a hook type. That is, when the insulating rod with a hook needs to be tested, the hook on the insulating rod can be connected to the hanging connection assembly 41; when the insulating rod without a hook needs to be tested, the insulating rod can be clamped on the testing frame 1 by the clamping connection assembly 42, which improves the applicability of this application.

[0046] Reference Figure 2 , 4Specifically, the hanging connection assembly 41 includes a first top rod 411 and an L-shaped hanging rod 412. The first top rod 411 is horizontally installed on the top of the detection frame 1, and the length direction of the first top rod 411 is parallel to the length direction of the crossbar 2, and the first top rod 411 is located directly above the crossbar 2. The L-shaped hanging rod 412 includes a vertical hanging rod and a horizontal hanging rod, and the shape formed by the vertical hanging rod and the horizontal hanging rod is L-shaped. Multiple L-shaped hanging rods 412 are arranged along the length direction of the first top rod 411, and the number of L-shaped hanging rods 412 is the same as the number of rod segment clamping mechanisms 3 on a crossbar 2. Each L-shaped hanging rod 412 is also located directly above a single rod segment clamping mechanism 3, that is, one L-shaped hanging rod 412 corresponds to one rod segment clamping mechanism 3 on a crossbar 2.

[0047] The buckle end of the insulating rod with the hook is directly attached to the horizontal section of the L-shaped hanging rod 412. At this time, the section of the insulating rod is clamped by the clamping groove 321, and the end of the rod is attached to the L-shaped hanging rod 412 and will not fall down, thus achieving the fixation of the insulating rod with the hook and achieving the effect of fixing the insulating rod with the hook in a more convenient way.

[0048] Combination Figure 2 , 4 Specifically, the clamp-type connecting assembly 42 includes a second push rod 421, a mounting base 422, and a snap-fit ​​piece 423. The second push rod 421 is located on the detection frame 1, below the first push rod 411 and above the multiple crossbars 2. The length direction of the second push rod 421 is consistent with that of the first push rod 411. Multiple mounting bases 422 are provided along the length direction of the second push rod 421, and each mounting base 422 corresponds to an L-shaped hanging rod 412. In this embodiment, the mounting base 422 is detachably connected to the second push rod 421 by bolts. The snap-fit ​​piece 423 is rotatably mounted on the mounting base 422. The upper part has a notch 4231 for engaging with the wall of the insulating rod. The notch allows the insulating rod to be inserted into the notch. A rubber layer is provided inside the notch, so that when the insulating rod is inserted into the notch, it can be tightly engaged with the insulating rod through the rubber layer. It is worth noting that in this embodiment, the engaging piece 423 can only rotate 180° on the mounting base 422, that is, 180° above the mounting base 422. After rotating the engaging piece 423, it can stably face the horizontal front, allowing the end of the insulating rod to be properly engaged.

[0049] When it is necessary to fix an insulating rod without a hook, flip the snap-fit ​​piece 423 on the mounting base 422 so that the snap-fit ​​groove 4231 on the snap-fit ​​piece 423 is directly above the clamping groove 321. Then, gradually pass the insulating rod without a hook through from bottom to top, or first deliberately lower the insulating rod without a hook below the clamping groove 321, and then move it vertically upward so that the end of the insulating rod without a hook is locked in the rubber layer of the clamping groove 321, thereby achieving fixation and making it more convenient to fix the insulating rod without a hook.

[0050] like Figure 1 , 5 As shown, the power-on testing mechanism 5 includes a distribution box 51, wires 52, upper clamps 53, and lower clamps 54. The distribution box 51 is mounted on the testing frame 1. The upper clamps 53 and lower clamps 54 are electrically connected to the distribution box 51 via wires 52. The number of upper clamps 53 and lower clamps 54 is the same as the number of rod segment clamping mechanisms 3 on a horizontal bar 2. The upper clamp 53 is clamped at the upper end of the insulating rod, and the lower clamp 54 is clamped at the lower end of the insulating rod. Then, the distribution box 51 is started, and it is observed whether current flows through the insulating rod. It is worth noting that the power-on testing mechanism 5 is an existing device equipped with a general insulation testing device. That is, after clamping both ends of the insulating rod with the upper clamps 53 and lower clamps 54, power is applied, and the resistance change corresponding to each clamped insulating rod is observed on the display screen of the distribution box 51. If the measured resistance is very large, it indicates that the insulating rod can be used normally.

[0051] like Figure 1 , 6 As shown, the testing frame 1 is also equipped with a quick unloading mechanism 6, which is used to remove all the hook-type insulating rods that are attached to multiple L-shaped hanging rods 412 at once. The quick unloading mechanism 6 includes a collection box 10, a press-start component 7, a transmission component 8, and a push component 9. The collection box 10 is equipped with a rubber pad and is installed on the testing frame 1 below the multiple attached insulating rods. The press-start component 7 is installed on the collection box 10, and the transmission component 8 and the push component 9 are both installed on the testing frame 1. When the press-start component 7 is squeezed by an external force, the transmission component 8 transmits the squeezing force to the push component 9, thereby pushing all the attached insulating rods simultaneously from the L-shaped hanging rods 412 into the collection box 10.

[0052] The external force directly presses and activates the component 7, which transmits the pressure to the push component 9 through the transmission component 8. This causes the push component 9 to generate a horizontal thrust, pushing the insulating rod with the hook out horizontally from the L-shaped hanging rod 412 and the clamping groove 321. At this time, the insulating rod with the hook will fall directly into the collection box 10 under the action of gravity and be stably stored under the buffering effect of the rubber pad, thereby achieving the effect of quickly unloading the insulating rod with the hook.

[0053] like Figure 6 , 7 As shown, specifically, the press-to-start assembly 7 includes a foot pedal 71, a slider 72, and a first spring 73; a groove 101 is vertically provided on the side wall of the collection box 10, the slider 72 is installed at one end of the foot pedal 71 and slidably disposed in the groove 101, the first spring 73 is installed between the inner wall of the groove 101 and the slider 72, the first spring 73 makes the foot pedal 71 always have a tendency to move vertically upward, that is, one end of the first spring 73 is connected to the slider 72 and the other end is connected to the inner top wall of the groove 101; the push assembly 9 includes a sliding rod 91, a sleeve 92, a second spring 93, a pull rope 94, and a rolling sleeve 95; one sleeve 92 is horizontally arranged on each side of the multiple insulating rods attached to the detection frame 1, one end of the sliding rod 91 is slidably inserted into the sleeve 92, and the second spring 93 is installed in the sleeve 92 and makes the sliding rod 91 always have a tendency to move into the sleeve 92. One end of the second spring 93 is connected to the inner end wall of the sleeve 92, and the other end is connected to the end wall of the sliding rod 91 located inside the sleeve 92; the pull rope 94 is arranged between the two sliding rods 91, and the pull rope 94 is in a horizontal taut state; multiple rolling sleeves 95 are rotatably sleeved on the pull rope 94; the transmission assembly 8 includes a first steering wheel 81, a second steering wheel 82, and a traction rope 83; a sliding strip hole 921 is opened on the side wall of the sleeve 92, and a connecting rod 911 extending out of the sliding strip hole 921 is provided on the sliding rod 91; the first steering wheel 81 is rotatably mounted on the detection frame 1, and the second steering wheel 82 is rotatably mounted on the detection frame 1 and located below the first steering wheel 81; a guide wheel 102 is also rotatably mounted on the side wall of the collection box 10; one end of the traction rope 83 is connected to the connecting rod 911, and the other end passes through the upper wheel surface of the first steering wheel 81, the lower wheel surface of the second steering wheel 82, and the upper wheel surface of the guide wheel 102 in sequence before connecting to the side wall of the pedal 71.

[0054] First, the worker presses the pedal 71 vertically downwards. The pedal 71 causes the slider 72 to move vertically downwards within the groove 101, thus causing the traction rope 83 to be pulled by the downward movement of the pedal 71, and the first spring 73 is in a stretched state. Under the guidance of the first steering wheel 81, the second steering wheel 82, and the guide wheel 102, the downward movement of the pedal 71 is ultimately converted into a pulling force on the connecting rod 911 along the direction of the sliding strip hole 921, which drives the sliding rod 91 to move into the sleeve 92. The second spring 93 is in a stretched state. At this time, the pull rope 94 between the two sliding rods 91 will move closer to the insulating rod side, and a sleeve is placed on the pull rope 94. The rolling sleeve 95 abuts against the side wall of the insulating rod and applies a horizontal pushing force to the insulating rod, eventually causing the insulating rod to detach horizontally from the L-shaped hanging rod 412 and the clamping groove 321, and fall into the collection box 10 under the action of gravity. This achieves a more intuitive and convenient effect of unloading the insulating rod with the hook. When the foot pedal 71 is released, the first spring 73 will drive the slider 72 to return to its vertical position, thus moving the foot pedal 71 vertically upward. At this time, the traction rope 83 will slowly return to its original position under the action of the second spring 93, and the sliding rod 91 will also partially slide out of the sleeve 92, allowing the pull rope 94 to return to its original position. This allows the quick unloading mechanism 6 to automatically reset after unloading the insulating rod.

[0055] The implementation principle of this application embodiment is as follows: When performing insulation testing on the insulating rods, multiple insulating rods can be clamped sequentially in the clamping groove 321. If the insulating rod has a hook, it is directly hooked onto the L-shaped hanging rod 412; if the insulating rod has a smooth surface and no hook, it is directly inserted into the slot 4231. Then, the upper clamp 53 and the lower clamp 54 are clamped at the upper and lower ends of the insulating rod. Next, the distribution box 51 is opened for testing. After the test is completed, if the insulating rod has a hook, the foot pedal 71 is pressed down forcefully, and the pull rope 94 will automatically push the insulating rod horizontally and finally enter the collection box 10. It is worth noting that in this embodiment, the position of the pull rope 94 can be located in the middle of the insulating rod, so that the insulating rod can be pushed horizontally normally. In addition, in this embodiment, an inclined baffle is provided at the front end of the collection box to prevent the insulating rod from falling out of the collection box.

[0056] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
