Description

Technical Field

[0001] The present invention relates to the technical field of power equipment detection, and particularly to an insulator strength detection device. Background Art

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding member, which can withstand voltage and mechanical stress. There are various types of insulators with different shapes. Although the structures and appearances of different types of insulators vary greatly, they are all composed of two main parts: an insulating part and a connecting fitting. An insulator is a special insulating control device that plays an important role in overhead transmission lines.

[0003] Insulators are indispensable components in the power system, and their main function is to support and insulate live conductors. During actual operation, insulators need to withstand mechanical loads, electrical loads, and the influence of various environmental factors, such as wind force, gravity, temperature changes, pollution, etc. Therefore, the strength of insulators is directly related to the safe and stable operation of the power system.

[0004] However, the existing technology can only simply detect the strength of the detected insulators, unable to automatically add the insulators to the detection device, and also unable to classify good and bad insulators. For this reason, we propose a strength detection device that can automatically place insulators and classify good and bad insulators. Summary of the Invention

[0005] One technical problem to be solved by the present application is: being able to automatically place insulators on the device, and also being able to classify good and bad insulators to achieve the classification of good and bad insulators.

[0006] To solve the above technical problem, an embodiment of the present application provides an insulator strength detection device, including a detection tabletop and two tray slides slidably connected to the detection tabletop. Both left and right ends of the detection tabletop are fixedly connected with end fixing vertical plates. Hydraulic telescopic rods I are fixedly connected to both end fixing vertical plates, and the two hydraulic telescopic rods I are respectively fixedly connected to the two tray slides. Four extrusion members capable of detecting the strength of insulators are fixedly connected to the detection tabletop.

[0007] In some embodiments, the extrusion member includes a support cross plate and a support slide slidably connected to the support cross plate. An outer wedge extrusion ring is fixedly connected to the support slide, and a hydraulic telescopic rod II is fixedly connected to the support cross plate. The inner end of the hydraulic telescopic rod II is fixedly connected to the support slide, and the four support cross plates are evenly fixedly connected to the detection tabletop.

[0008] In some embodiments, a fixed support sliding column is fixedly connected to the detection desktop, a lifting support plate is slidably connected to the fixed support sliding column, and two transverse moving square columns are slidably connected to the lifting support plate. The inner ends of the two transverse moving square columns are fixedly connected with a receiving conical cavity.

[0009] In some embodiments, a reduction motor is fixedly connected to the fixed support sliding column, a transmission lead screw is fixedly connected to the output shaft of the reduction motor, and the transmission lead screw is in threaded transmission connection with the lifting support plate.

[0010] In some embodiments, a limiting cross column is fixedly connected to the lifting support plate, a positioning sliding column is slidably connected to the limiting cross column, and the positioning sliding column is slidably connected to the lifting support plate and contacts the two transverse moving square columns.

[0011] In some embodiments, an inclined plane support plate is fixedly connected to the fixed support sliding column, and a contact inclined plate is fixedly connected to the limiting cross column.

[0012] In some embodiments, a plurality of support cylinders are fixedly connected to the lower part of the detection desktop, and a bottom support cross plate is fixedly connected to the lower part of the plurality of support cylinders.

[0013] In some embodiments, an isolation vertical plate is fixedly connected to the bottom support cross plate, and a downward sliding inclined plate is rotatably connected to the isolation vertical plate.

[0014] In some embodiments, two limiting inclined plates are fixedly connected to the isolation vertical plate.

[0015] In some embodiments, a hydraulic expansion rod III is fixedly connected to each of the two limiting inclined plates.

[0016] The present invention has at least the following beneficial effects:

[0017] 1. Place the insulator into the two receiving conical cavities, and let the lifting support plate move downward. Also, since the outer ends of the four outer wedge extrusion rings are designed with inclined planes, when the two receiving conical cavities move downward and contact the four outer wedge extrusion rings, the two receiving conical cavities will slide outward simultaneously, so that the two receiving conical cavities are separated. At this time, the insulators located in the two receiving conical cavities will automatically fall.

[0018] 2. The isolation vertical plate can be used to strengthen the fixation between the detection desktop and the bottom support cross plate, and the isolation vertical plate can be used to separate the bottom support cross plate into two spaces. The two spaces can store qualified insulators and unqualified insulators respectively. The detected insulators that fall through the two support slide plates will fall onto the downward sliding inclined plate, and then slide down through the downward sliding inclined plate. Since the angle of the downward sliding inclined plate is different, the sliding direction of the insulators will also be different, so as to realize the separate storage of qualified insulators and unqualified insulators, reduce the later sorting time, and reduce the work burden.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: Please refer to Figures 1 - 5 , the present invention provides a technical solution: an insulator strength detection device, including a detection tabletop 101 and two support plate sliders 102 slidably connected to the detection tabletop 101. Both left and right ends of the detection tabletop 101 are fixedly connected with end fixing vertical plates 103. Hydraulic expansion rods I 104 are fixedly connected to both of the two end fixing vertical plates 103, and the two hydraulic expansion rods I 104 are respectively fixedly connected to the two support plate sliders 102. Four extrusion members capable of detecting the strength of the insulator are fixedly connected to the detection tabletop 101.

[0033] Further, the detection tabletop 101 can provide a placement space for the insulator. A through hole is provided at the center of the detection tabletop 101. The lateral direction of the detection tabletop 101 is designed with a hollow structure, and a notch slideway is also provided below it. The hollow part of the detection tabletop 101 can provide a sliding space for two support slide plates 102. By using the two support slide plates 102, the through hole at the center of the detection tabletop 101 can be sealed. When the insulator is placed on the detection tabletop 101, the insulator will directly fall onto the two support slide plates 102. Semi - circles are provided at the centers where the two support slide plates 102 contact, and the two semi - circles form a circle, which can provide a space for the protruding screw of the insulator to pass through, so as to place the insulator stably on the two support slide plates 102. Raised parts are fixedly connected to the inner ends below the two support slide plates 102, and the raised parts are slidably connected in the notch slideway below the detection tabletop 101, realizing the limit treatment of the two support slide plates 102, enabling the two support slide plates 102 to only slide left and right, and also providing a fixed space for two hydraulic expansion rods I104. The two end - fixing vertical plates 103 can provide a blocking space for the through hole and the notch slideway on the detection tabletop 101 to prevent the two support slide plates 102 from sliding away from the detection tabletop 101. The two end - fixing vertical plates 103 can also provide a fixed space for two hydraulic expansion rods I104. The two hydraulic expansion rods I104 are connected to the power supply through wires and switches. After starting the two hydraulic expansion rods I104, the two support slide plates 102 can be driven to move inwards or outwards simultaneously. When the two support slide plates 102 contact, a placement space for the insulator is provided. After the insulator is stably placed on the two support slide plates 102, the strength of the insulator is detected. After the insulator is detected, the two support slide plates 102 are separated. At this time, the detected insulator will be discharged through the gap between the two support slide plates 102. The strength detection of the insulator is completed by using four extrusion components to perform extrusion treatment on the four sides of the insulator, ensuring that each insulator used is a qualified product.

[0034] Place the insulator on the two support slide plates 102. At this time, the screw of the insulator will pass through the two support slide plates 102, completing the stable placement of the insulator on the two support slide plates 102. At this time, start the four extrusion components, and let the four extrusion components move inwards simultaneously to perform extrusion treatment on the insulator. After applying a certain force, observe the state of the insulator. If the insulator does not break, it is in a qualified state. If the insulator cannot withstand the extrusion force, it is an unqualified product. After the strength detection of the insulator is completed, start the two support slide plates 102, and let the two support slide plates 102 retract, which can drive the two support slide plates 102 to move inwards simultaneously. At this time, the two support slide plates 102 are separated, and the detected insulator will directly fall through the gap between the two support slide plates 102.

[0035] Example 2: Please refer to Figures 1 - 4 The present invention provides a technical solution: an insulator strength detection device, the extrusion component includes a supporting cross plate 201 and a supporting slide plate 202 slidably connected to the supporting cross plate 201, an outer wedge extrusion ring 203 is fixedly connected to the supporting slide plate 202, a hydraulic telescopic rod II204 is fixedly connected to the supporting cross plate 201, the inner end of the hydraulic telescopic rod II204 is fixedly connected to the supporting slide plate 202, and four supporting cross plates 201 are evenly fixedly connected to the detection desktop 101.

[0036] Furthermore, the supporting cross plate 201 can provide a sliding space for the supporting slide plate 202, and the supporting slide plate 202 can provide a fixed space for the outer wedge extrusion ring 203. The outer wedge extrusion ring 203 can be used to extrude the insulator. The hydraulic telescopic rod II204 is connected to the power supply through a wire and a switch. After the hydraulic telescopic rod II204 is started, the outer wedge extrusion ring 203 can be driven to move inward through the supporting slide plate 202. The four hydraulic telescopic rods II204 are all controlled by the same switch. When the insulator is stably placed on the two supporting slide plates 102, the four hydraulic telescopic rods II204 are started to drive the four outer wedge extrusion rings through the four supporting slide plates 202. 203 moves inward at the same time, thereby realizing the extrusion and fixing processing of the insulator, and the inner end faces of the four outer wedge extrusion rings 203 are installed with pressure gauges, through which the extrusion pressure generated by the four outer wedge extrusion rings 203 can be observed, so that the four outer wedge extrusion rings 203 can generate the maximum extrusion pressure that the insulator can withstand, and the damage of the insulator can be observed. If the insulator withstands the maximum extrusion pressure without being damaged, it is a qualified product. If the insulator withstands the maximum extrusion pressure and is damaged, it is an unqualified product. When the insulator is inspected, the two hydraulic telescopic rods I104 are started, allowing the two row support slides 102 to slide outward at the same time to discharge the inspected insulators.

[0037] Example 3: Please refer to Figure 1 , 2 And 6-8, the present invention provides a technical solution: an insulator strength detection device, the detection table top 101 is fixedly connected with a fixed support slide 301, the fixed support slide 301 is slidably connected with a lifting support plate 302, the lifting support plate 302 is slidably connected with two transverse square columns 303, and the inner ends of the two transverse square columns 303 are fixedly connected with a receiving cone cavity 304.

[0038] Furthermore, the fixed support slide column 301 can provide sliding space for the lifting support plate 302, realize the limit processing of the lifting support plate 302, so that the lifting support plate 302 can only slide up and down, and the lifting support plate 302 can also provide sliding space for the two transverse square columns 303, and the two transverse square columns 303 can provide fixed space for the two receiving cone cavities 304. The two receiving cone cavities 304 are designed with a conical surface structure, and the insulator can be placed in the two receiving cone cavities 304. The two transverse square columns 303 are both sleeved with springs 1, and the outer ends of the two springs 1 are respectively in contact with the lifting support plate 302, and the inner ends of the two springs 1 are respectively in contact with the two receiving cone cavities 304, so that the elastic force generated by the two springs 1 acts on the two receiving cone cavities 304, so that the two receiving cone cavities 304 are tightly attached to each other. Then, place the insulator into the two receiving cone cavities 304, and let the lifting support plate 302 move downward. Because the outer ends of the four outer wedge extrusion rings 203 are all designed with inclined surfaces, when the two receiving cone cavities 304 move downward and contact the four outer wedge extrusion rings 203, the two receiving cone cavities 304 will slide outward at the same time, thereby separating the two receiving cone cavities 304. At this time, the insulator located in the two receiving cone cavities 304 will automatically fall down, and the screws of the insulator will fall into the circle between the two supporting slides 102, and the insulator will fall smoothly on the two supporting slides 102, so as to realize the automatic placement of the insulator on the two supporting slides 102. After the insulator is stably placed on the two supporting slides 102, the insulator is subjected to strength extrusion detection.

[0039] Example 4: Please refer to Figure 1 , 2 And 6, the present invention provides a technical solution: an insulator strength detection device, the fixed support slide column 301 is fixedly connected with a reduction motor 401, the output shaft of the reduction motor 401 is fixedly connected with a transmission screw 402, and the transmission screw 402 is connected to the lifting support plate 302 through threaded transmission.

[0040] Furthermore, the reduction motor 401 is connected to the power supply through a wire and a switch. After the reduction motor 401 is started, the transmission screw 402 can be driven to rotate, and the rotating transmission screw 402 will drive the lifting support plate 302 to lift and lower, thereby driving the insulator placed between the two receiving cone cavities 304 to lift and lower, so as to achieve the stable placement of the insulator on the two supporting slides 102. When the lifting support plate 302 moves to the highest point, the four hydraulic telescopic rods II204 will be started and extended to achieve the strength detection of the insulator. After the detection is completed, the four hydraulic telescopic rods II204 will retract to their original positions.

[0041] Example 5: Please refer to Figure 1 , 2As shown in FIGS. 6 - 8, the present invention provides a technical solution: an insulator strength detection device. A limiting cross - column 501 is fixedly connected to the lifting support plate 302. A positioning sliding column 502 is slidably connected to the limiting cross - column 501. The positioning sliding column 502 is slidably connected to the lifting support plate 302 and contacts two transverse moving square columns 303.

[0042] Furthermore, the limiting cross - column 501 can provide a sliding space for the positioning sliding column 502. The positioning sliding column 502 is also slidably connected to the lifting support plate 302 to realize the limiting treatment of the positioning sliding column 502, enabling the positioning sliding column 502 to only slide back and forth. A spring II is sleeved on the positioning sliding column 502. The front and rear ends of the spring II respectively contact the limiting cross - column 501 and the lifting support plate 302. The elastic force generated by the spring II will act on the positioning sliding column 502, causing the two ends of the positioning sliding column 502 to respectively contact the two transverse moving square columns 303. Circular holes are provided on both of the two transverse moving square columns 303. When the two transverse moving square columns 303 move outward, the circular holes on the two transverse moving square columns 303 also slide outward. After the two transverse moving square columns 303 move a certain distance, the positioning sliding column 502 will be slidably connected to the circular holes on the two transverse moving square columns 303. At this time, the two transverse moving square columns 303 will be limited and fixed by the positioning sliding column 502. At this time, the two receiving conical cavities 304 will be completely separated, ensuring that the insulator located between the two receiving conical cavities 304 will fall smoothly.

[0043] Embodiment 6: Please refer to Figure 1 、 2 As shown in FIGS. 6 - 8, the present invention provides a technical solution: an insulator strength detection device. An inclined - plane support plate 601 is fixedly connected to the fixed support sliding column 301, and a contact inclined - plane 602 is fixedly connected to the limiting cross - column 501.

[0044] Furthermore, the inclined - plane support plate 601 and the contact inclined - plane 602 are used in cooperation. When the limiting cross - column 501 moves upward, it will drive the contact inclined - plane 602 to move upward. When the contact inclined - plane 602 contacts the inclined - plane support plate 601, the contact inclined - plane 602 slides backward, ultimately driving the limiting cross - column 501 to move backward. At this time, the limiting cross - column 501 will slide out of the circular holes on the two transverse moving square columns 303. At this time, the limitation of the two transverse moving square columns 303 is released. The elastic force generated by the two springs I drives the two receiving conical cavities 304 to slide inward, causing the two receiving conical cavities 304 to contact each other again. Place a new insulator between the two receiving conical cavities 304 and cycle in turn to realize the automatic detection of multiple insulators. When the two receiving conical cavities 304 contact each other again, it is also when the lifting support plate 302 moves to the highest point. At this time, the four hydraulic expansion rods II 204 will be activated.

[0045] Embodiment 7: Please refer to Figure 1 、 2As shown in FIGS. 9, the present invention provides a technical solution: an insulator strength detection device, wherein a plurality of support cylinders 701 are fixedly connected below the detection tabletop 101, and a base support cross plate 702 is fixedly connected below the plurality of support cylinders 701.

[0046] Furthermore, the plurality of support cylinders 701 play a role in supporting and fixing, and the detection tabletop 101 and the base support cross plate 702 are fixed together through the plurality of support cylinders 701. A plurality of floor anchor round holes are provided at the bottom of the base support cross plate 702, and the base support cross plate 702 can be fixed on the ground through the plurality of floor anchor round holes, so as to firmly fix the device on the ground and complete the strength detection process of the insulator.

[0047] Example 8: Please refer to Figure 1 、 2 As shown in FIGS. 9, the present invention provides a technical solution: an insulator strength detection device, wherein an isolation vertical plate 801 is fixedly connected to the base support cross plate 702, and a downward-sliding inclined plate 802 is rotatably connected to the isolation vertical plate 801.

[0048] Furthermore, the isolation vertical plate 801 can reinforce the fixation between the detection tabletop 101 and the base support cross plate 702, and the isolation vertical plate 801 can separate the base support cross plate 702 into two spaces. The two spaces can store qualified insulators and unqualified insulators respectively. The detected insulators falling through the two support sliding plates 102 will fall onto the downward-sliding inclined plate 802, and then slide down through the downward-sliding inclined plate 802. Since the angles of the downward-sliding inclined plate 802 are different, the sliding directions of the insulators will also be different, so as to realize the separate storage of qualified insulators and unqualified insulators, reduce the later sorting time, and lighten the work burden.

[0049] Example 9: Please refer to Figure 1 、 2 As shown in FIGS. 9, 10, the present invention provides a technical solution: an insulator strength detection device, wherein two limit inclined plates 901 are fixedly connected to the isolation vertical plate 801.

[0050] Furthermore, the two limit inclined plates 901 play a role in supporting and limiting. When the downward-sliding inclined plate 802 rotates left and right, it will contact the two limit inclined plates 901 respectively, so as to realize the support and limit treatment of the downward-sliding inclined plate 802 and make the downward-sliding inclined plate 802 at a suitable angle.

[0051] Example 10: Please refer to Figure 1 、 2 As shown in FIGS. 9, 10, the present invention provides a technical solution: an insulator strength detection device, wherein hydraulic expansion rods III 902 are fixedly connected to both of the two limit inclined plates 901.

[0052] Further, after the hydraulic telescopic rod III902 is activated, the hydraulic telescopic rod III902 will move upward and will contact the downward-sliding inclined plate 802. At this time, the downward-sliding inclined plate 802 will rotate. According to the detection result of the insulator, the corresponding hydraulic telescopic rod III902 will be activated, thereby changing the angle of the downward-sliding inclined plate 802 to make the downward-sliding inclined plate 802 at the correct inclination angle and ensuring that the insulator falls into the correct storage space.
