Description

Technical Field

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

[0002] Insulators are devices installed between conductors of different potentials or between conductors and grounded components, which can withstand voltage and mechanical stress. There are many types of insulators with different shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting fittings. Insulators are a special type of insulating control that can play an important role in overhead transmission lines.

[0003] Insulators are an indispensable component in the power system. Their main function is to support and insulate live conductors. In actual operation, insulators need to withstand mechanical loads, electrical loads, and various environmental factors, such as wind, gravity, temperature changes, and contamination. Therefore, the strength of insulators is directly related to the safe and stable operation of the power system.

[0004] The existing technology can only simply test the strength of the insulators being tested, but cannot automatically add the insulators to the testing device, and cannot classify good and bad insulators. To this end, we propose a strength testing device that can automatically place insulators and classify good and bad insulators. Summary of the invention

[0005] A technical problem to be solved by the present application is that insulators can be automatically placed on the device, and good and bad insulators can be classified to achieve classification processing of good and bad insulators.

[0006] In order to solve the above technical problems, an embodiment of the present application provides an insulator strength detection device, including a detection tabletop and two supporting slides slidably connected to the detection tabletop, the left and right ends of the detection tabletop are fixedly connected with end fixed vertical plates, the two end fixed vertical plates are fixedly connected with a hydraulic telescopic rod I, the two hydraulic telescopic rods I are respectively fixedly connected to the two supporting slides, and four extrusion components capable of detecting the strength of the insulator are fixedly connected to the detection tabletop.

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

[0008] In some embodiments, a fixed support slide is fixedly connected to the detection tabletop, a lifting support plate is slidably connected to the fixed support slide, two transverse square columns are slidably connected to the lifting support plate, and the inner ends of the two transverse square columns are fixedly connected to a receiving cone cavity.

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

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

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

[0012] In some embodiments, a plurality of supporting cylinders are fixedly connected to the bottom of the detection tabletop, and a bottom supporting horizontal plate is fixedly connected to the bottom of the plurality of supporting cylinders.

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

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

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

[0016] The present invention has at least the following beneficial effects: 1. Place the insulator in the two receiving cone cavities and move the lifting support plate downward. Because the outer ends of the four outer wedge extrusion rings are all designed with inclined surfaces, when the two receiving cone cavities move downward and contact the four outer wedge extrusion rings, the two receiving cone cavities will slide outward at the same time, thereby separating the two receiving cone cavities. At this time, the insulators in the two receiving cone cavities will automatically fall.

[0017] 2. The isolation vertical plate can be used to reinforce the fixation between the detection table and the bottom support horizontal plate, and the isolation vertical plate can be used to separate the bottom support horizontal plate into two spaces. The two spaces can store qualified insulators and unqualified insulators respectively. The insulators that have been tested and dropped through the two support slides will fall onto the downward inclined plate, and then slide down through the downward inclined plate. The angles of the downward inclined plate are different, and the directions in which the insulators slide will also be different, thereby realizing the separate storage of qualified insulators and unqualified insulators, reducing the time for later sorting and alleviating the workload.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-5The present invention provides a technical solution: an insulator strength detection device, comprising a detection desktop 101 and two row-supporting slides 102 slidably connected to the detection desktop 101, the left and right ends of the detection desktop 101 are fixedly connected with end-fixed vertical plates 103, the two end-fixed vertical plates 103 are fixedly connected with hydraulic telescopic rods I104, the two hydraulic telescopic rods I104 are respectively fixedly connected to the two row-supporting slides 102, and four extrusion components capable of detecting the strength of insulators are fixedly connected to the detection desktop 101.

[0023] Furthermore, the detection desktop 101 can provide a space for placing an insulator. A transparent opening is provided at the center of the detection desktop 101. The detection desktop 101 is designed as a hollow structure in the horizontal direction, and a notched slide is provided below it. The hollow opening of the detection desktop 101 can provide a sliding space for two supporting slides 102. The two supporting slides 102 can be used to seal the transparent opening at the center of the detection desktop 101. When the insulator is placed on the detection desktop 101, the insulator will fall directly onto the two supporting slides 102. The centers of the two supporting slides 102 are both provided with semicircles, and the two semicircles form a circle. The circle can provide a space for the protruding screws of the insulator to pass through, so that the insulator can be stably placed on the two supporting slides 102. The inner ends of the two supporting slides 102 are fixedly connected with protrusions, and the protrusions are slidably connected in the notched slide below the detection desktop 101. The two supporting slide plates 102 are limited so that the two supporting slide plates 102 can only slide left and right, and can also provide a fixed space for the two hydraulic telescopic rods I104. The two end fixed vertical plates 103 can provide a blocking space for the transparent opening and the notch slideway on the detection table 101 to prevent the two supporting slide plates 102 from sliding off the detection table 101. The two end fixed vertical plates 103 can also provide a fixed space for the two hydraulic telescopic rods I104. The two hydraulic telescopic rods I104 are connected to the power supply through wires and switches. After the two hydraulic telescopic rods I104 are started It can drive the two row-supporting slide plates 102 to move inward or outward at the same time. When the two row-supporting slide plates 102 are in contact, space is provided for the insulator to be placed. When the insulator is stably placed on the two row-supporting slide plates 102, the strength of the insulator is tested. When the insulator is tested, the two row-supporting slide plates 102 are separated. At this time, the tested insulator will be discharged through the gap between the two row-supporting slide plates 102. Four extrusion components are used to extrude the four sides of the insulator, thereby completing the strength test of the insulator to ensure that each insulator used is a qualified product.

[0024] Place the insulator on the two supporting slides 102. At this time, the screws of the insulator will pass through the two supporting slides 102, and the insulator will be placed stably on the two supporting slides 102. At this time, start the four extrusion components and let the four extrusion components move inward at the same time to achieve the extrusion treatment of the insulator. After applying a certain force, observe the state of the insulator. If the insulator is not broken, it is in a qualified state. If the insulator cannot withstand the extrusion force, it is an unqualified product. After the insulator strength test is completed, start the two supporting slides 102 and let the two supporting slides 102 retract, which can drive the two supporting slides 102 to move inward at the same time. At this time, the two supporting slides 102 are disengaged, and the insulator that has been tested will fall directly through the gap between the two supporting slides 102.

[0025] Example 2: Please refer to Figure 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.

[0026] 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.

[0027] Example 3: Please refer to Figure 1 , 2And 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] Example 5: Please refer to Figure 1 , 2 And 6-8, the present invention provides a technical solution: an insulator strength detection device, the lifting support plate 302 is fixedly connected to a limiting horizontal column 501, the limiting horizontal column 501 is slidably connected to a positioning slide column 502, the positioning slide column 502 is slidably connected to the lifting support plate 302 and contacts with two transverse square columns 303.

[0032] Furthermore, the limiting cross column 501 can provide sliding space for the positioning slide post 502, and the positioning slide post 502 is also slidably connected to the lifting support plate 302 to realize the limiting processing of the positioning slide post 502, so that the positioning slide post 502 can only slide forward and backward. A spring II is provided on the positioning slide post 502, and the front and rear ends of the spring II are respectively in contact with the limiting cross column 501 and the lifting support plate 302. The elastic force generated by the spring II will act on the positioning slide post 502, so that the two ends of the positioning slide post 502 are respectively in contact with the two transverse square columns 303, and the two transverse square columns 303 are both provided with circular holes. When the two transverse square columns 303 move outward, the circular holes on the two transverse square columns 303 also slide outward. When the two transverse square columns 303 move a certain distance, the positioning slide post 502 will be slidably connected in the circular holes on the two transverse square columns 303. At this time, the two transverse square columns 303 will be limited and fixed by the positioning slide column 502, and the two receiving cone cavities 304 will be completely separated, ensuring that the insulator located between the two receiving cone cavities 304 will fall smoothly.

[0033] Example 6: Please refer to Figure 1 , 2 And 6-8, the present invention provides a technical solution: an insulator strength detection device, wherein the fixed support sliding column 301 is fixedly connected with an inclined support plate 601, and the limiting horizontal column 501 is fixedly connected with a contact inclined plate 602.

[0034] Furthermore, the inclined support plate 601 and the contact inclined plate 602 are used in conjunction with each other. When the limiting horizontal column 501 moves upward, the contact inclined plate 602 will be driven to move upward. When the contact inclined plate 602 contacts the inclined support plate 601, the contact inclined plate 602 slides backward, and finally drives the limiting horizontal column 501 to move backward. At this time, the limiting horizontal column 501 will slide away from the round holes on the two transverse square columns 303. At this time, the limiting of the two transverse square columns 303 is released, and the elastic force generated by the two springs I drives the two receiving cone cavities 304 to slide inward, so that the two receiving cone cavities 304 are in contact again, and a new insulator is placed between the two receiving cone cavities 304, and the cycle is repeated in sequence to realize automatic detection of multiple insulators. When the two receiving cone cavities 304 are in contact again, the lifting support plate 302 moves to the highest point, and the four hydraulic telescopic rods II204 will be started.

[0035] Example 7: Please refer to Figure 1 , 2 9. The present invention provides a technical solution: an insulator strength detection device, wherein a plurality of supporting cylinders 701 are fixedly connected to the bottom of the detection tabletop 101, and a bottom supporting horizontal plate 702 is fixedly connected to the bottom of the plurality of supporting cylinders 701.

[0036] Furthermore, multiple supporting cylinders 701 play a supporting and fixing role. The detection tabletop 101 and the bottom supporting cross plate 702 are fixed together through the multiple supporting cylinders 701. The bottom of the bottom supporting cross plate 702 is provided with multiple anchor circular holes. The bottom supporting cross plate 702 can be fixed to the ground through the multiple anchor circular holes, so that the device can be firmly fixed on the ground, completing the strength detection of the insulator.

[0037] Example 8: Please refer to Figure 1 , 2 9. The present invention provides a technical solution: an insulator strength detection device, wherein the bottom support horizontal plate 702 is fixedly connected to an isolation vertical plate 801, and the isolation vertical plate 801 is rotatably connected to a lower sliding inclined plate 802.

[0038] Furthermore, the isolation vertical plate 801 can be used to reinforce the fixation between the detection table top 101 and the bottom support horizontal plate 702, and the isolation vertical plate 801 can be used to separate the bottom support horizontal plate 702 into two spaces, and the two spaces can respectively store qualified insulators and unqualified insulators. The insulators that have been tested and dropped through the two supporting slides 102 will fall onto the downward sliding inclined plate 802, and then slide down through the downward sliding inclined plate 802. The angles of the downward sliding inclined plate 802 are different, and the directions in which the insulators slide will also be different, thereby achieving the storage of qualified insulators and unqualified insulators separately, reducing the time for later sorting and alleviating the workload.

[0039] Example 9: Please refer to Figure 1 , 2 , 9 and 10, the present invention provides a technical solution: an insulator strength detection device, wherein two limiting inclined plates 901 are fixedly connected to the isolation vertical plate 801.

[0040] Furthermore, the two limiting inclined plates 901 play a supporting and limiting role. When the downwardly sliding inclined plate 802 rotates left and right, it will contact the two limiting inclined plates 901 respectively, thereby achieving supporting and limiting processing for the downwardly sliding inclined plate 802, so that the downwardly sliding inclined plate 802 is at a suitable angle.

[0041] Example 10: Please refer to Figure 1 , 2 , 9 and 10, the present invention provides a technical solution: an insulator strength detection device, wherein the two limit inclined plates 901 are fixedly connected with a hydraulic telescopic rod III902.

[0042] Furthermore, after the hydraulic telescopic rod III902 is started, the hydraulic telescopic rod III902 will move upward and will contact the downward inclined plate 802. At this time, the downward inclined plate 802 will rotate. According to the detection result of the insulator, the corresponding hydraulic telescopic rod III902 will be started, thereby changing the angle of the downward inclined plate 802, so that the downward inclined plate 802 is at the correct inclination angle, ensuring that the insulator falls into the correct storage space.
