Description

Technical Field

[0001] The present invention belongs to the field of strength detection devices, and in particular relates to a strength detection device for electric hardware. Background Art

[0002] Power fittings are a general term for various metal components used to connect, fix, support, and protect transmission lines, cables, insulators, and other power equipment in power systems. Although relatively small in size, they are indispensable basic components in power transmission networks, and their performance is directly related to the safety, stability, and economy of the power grid. The power fitting strength testing device is a professional equipment used to test the mechanical load bearing capacity of power fittings (such as U-shaped hanging rings, etc.) under different working conditions. Its core function is to ensure that power fittings have sufficient strength and stability in actual operation to avoid safety accidents or power system failures caused by insufficient strength. However, existing power fitting strength testing devices are unable to perform strength testing on power fittings of different lengths, which is somewhat inconvenient.

[0003] A Chinese patent with patent publication number CN222689560U discloses a device for testing the strength of electrical fittings. The device uses a bidirectional screw to drive a sliding frame to move, facilitating strength testing of electrical fittings of different lengths. This prevents short electrical fittings from being difficult to test during testing. However, when testing a large number of electrical fittings from different batches, the device requires manual placement of the electrical fittings one by one on a protective plate and clamping and securing them with two sets of sliding frames, resulting in low overall efficiency and reduced overall testing efficiency.

DETAILED DESCRIPTION

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] See also Figure 1-11As shown, in this embodiment, a power hardware strength testing device is provided, including a base 1, a testing platform 2 is provided on the top of the testing platform 2, a turntable 3 is rotatably connected to the testing platform 2 through a first rotating shaft 4, a groove wheel intermittent driving mechanism 11 is provided at the bottom of the testing platform 2 for driving the first rotating shaft 4 to intermittently rotate, a plurality of placement plates 5 are provided on the turntable 3 along its circumference, a clamping assembly 7 is provided on the placement plate 5, a pressure detection device 6 is provided on the testing platform 2 relative to the placement plate 5, a conveyor belt mechanism 12 is provided on the conveyor belt mechanism 12, and a The fixed plate 13 is provided with a transport assembly 9 for transporting the electrical fittings on the conveyor belt mechanism 12 to the placement plate 5. The transport assembly 9 includes a sliding plate 92, which is slidably arranged on the fixed plate 13. A cylinder 91 for driving the sliding plate 92 to slide is fixedly installed on the fixed plate 13, and a lifting plate 93 is penetrated and slidably arranged on the sliding plate 92. An electromagnetic suction cup 96 is provided at the bottom of the lifting plate 93, and a sliding rod 94 is fixedly installed on the top of the lifting plate 93. A slide rail 95 for the sliding rod 94 is provided on the fixed plate 13.

[0023] Specifically, in this embodiment, a controller 10 for all devices is fixedly installed on the base 1. At the same time, a fixed plate 13 is fixedly installed on the conveyor belt mechanism 12, and the fixed plate 13 is arranged relative to the placement plate 5 on the turntable 3. The pressure detection device 6 and the transport assembly 9 are staggered. Secondly, the slide rail 95 includes a first horizontal section 951, a lifting section 952 and a second horizontal section 953 that are connected in sequence along the direction from the conveyor belt mechanism 12 to the placement plate 5. The height of the first horizontal section 951 is higher than that of the second horizontal section 953. The lifting section 952 is tilted and connected between the first horizontal section 951 and the second horizontal section 953. The tilt angle can be adjusted according to actual conditions. When in operation, the electrical hardware moves with the conveyor belt mechanism 12 to the bottom of the fixed plate 13 At the designated position, the sliding plate 92 is located on the side of the fixed plate 13 close to the conveyor belt. At this time, the slide bar 94 is in the first horizontal section 951 of the slide rail 95 (at a higher height). The lifting plate 93 drives the electromagnetic suction cup 96 to contact the power hardware on the conveyor belt mechanism 12. The electromagnetic suction cup 96 is energized to generate magnetic force, which adsorbs the hardware to the bottom of the electromagnetic suction cup 96 to ensure that the hardware can stably take out materials. Then, the controller 10 controls the cylinder 91 to push the sliding plate 92 to slide toward the placement plate 5. The slide bar 94 slides along the first horizontal section 951 to the connection between the lifting section 952 and the slide bar 94 enters the lifting section 952. Since the height of the first horizontal section 951 is higher than the second horizontal section 953, the slide bar 94 slides down along the inclined track, driving the lifting plate 93 to move downward. The slide bar 94 moves along the lifting section 952. Slide into the second horizontal section 953 (lower height), at this time the lifting plate 93 is in a low position, the electric hardware is adsorbed on the electromagnetic suction cup 96 and moves with the sliding plate 92 to above the placement plate 5, at this time the bottom of the electric hardware is in contact with the placement plate 5, after reaching the specified position, the cylinder 91 stops running, and the controller 10 controls the clamping assembly 7 on the placement plate 5 to clamp the hardware to ensure that the hardware position is stable during detection, then the electromagnetic suction cup 96 is powered off, the hardware loses magnetic adsorption, the controller 10 controls the cylinder 91 to reverse drive the sliding plate 92 to move toward the fixed plate 13, the slide bar 94 enters the second horizontal section 953 from the second horizontal section 953 through the lifting section 952, so that the electromagnetic suction cup 96 moves again to above the conveyor belt mechanism 12 to adsorb the electric hardware on it, and then Afterwards, the controller 10 controls the grooved wheel mechanism at the bottom of the detection platform 2 to drive the first rotating shaft 4 to rotate intermittently, and each time it rotates an angle, the placement plate 5 (with the hardware placed) is moved to the bottom of the pressure detection device 6. The pressure detection device 6 applies pressure to the hardware, collects data through the force sensor and the displacement sensor, and completes the strength detection. After the detection, the grooved wheel intermittent driving mechanism 11 moves the tested motor 71 hardware to the unloading position, and then the above steps can be repeated, so that the handling component 9 continues to take and discharge materials, and the turntable 3 rotates intermittently to realize the continuous detection of multi-station hardware. The overall structure has simple operation steps and a high degree of automation, which realizes the automatic handling and intermittent detection of power hardware, improves the detection efficiency, reduces manual operation, and reduces labor intensity.At the same time, the clamping assembly 7 and the pressure detection device 6 can more accurately detect the strength of the electrical hardware.

[0024] It should be noted that, in this embodiment, the conveyor belt mechanism 12 is a belt conveyor, and the structure and working principle of the sheave intermittent drive mechanism 11 can be referred to Figure 3 and Figure 4 Its structure, working principle and installation position are all existing technologies and will not be described here; further, in this embodiment, this device is suitable for performing pressure resistance testing on U-shaped hanging rings, and is not limited in other embodiments.

[0025] In this embodiment, if Figures 1 to 7As shown, it also includes a position adjustment component 8, which is arranged on the fixed plate 13. The position adjustment component 8 includes a first slider 81, which is slidably arranged on the fixed plate 13, a rotating plate 84, which is rotatably arranged at the bottom of the lifting plate 93 through a third rotating shaft 86, and a first bevel gear 87 is sleeved on the third rotating shaft 86 and fixedly connected. The lifting plate 93 is rotatably connected to a second bevel gear 88 that meshes with the first bevel gear 87 through a second rotating shaft 85. A second connecting rod 83 is vertically fixedly installed on the second rotating shaft 85, and a first connecting rod 82, whose two ends are respectively hinged to the second connecting rod 83 and the first slider 81. The fixed plate 13 is provided with a sliding plate for the first slider 81. The first slide groove 14 is extended along the sliding direction of the lifting plate 93. The diameter of the first bevel gear 87 is larger than the diameter of the second bevel gear 88. Two sets of distance sensors 15 are relatively fixedly installed along the sliding plate 92 on the fixed plate 13. Specifically, in this embodiment, the U-shaped hanging ring is in a flat state when it is located on the conveyor belt mechanism 12. When the electromagnetic suction cup 96 adsorbs the U-shaped hanging ring on the conveyor belt mechanism 12 (the electromagnetic suction cup 96 is adsorbed on the straight rod on one side of the U-shaped hanging ring) and moves to the placement plate 5, when the first slider 81 slides on the fixed plate 13, the second connecting rod 83 is driven to rotate through the first connecting rod 82, and the second connecting rod 83 rotates to make the second The bevel gear 88 rotates, and the second bevel gear 88 meshes with the first bevel gear 87, thereby driving the rotating plate 84 to rotate around the third rotating shaft 86, thereby adjusting the position of the electromagnetic suction cup 96. When the slide bar 94 moves to the end of the second horizontal section 953, the rotating plate 84 rotates 90 degrees, so that the U-shaped hanging ring on the electromagnetic suction cup 96 is rotated from a lying state to a vertical state. At the same time, the U-shaped hanging ring moves to the placement plate 5 and is located in the clamping groove of the clamping assembly 7. At the same time, in this embodiment, the sliding plate 92 will sense the distance sensor 15 when it moves to the initial end and the end end. When the sliding plate 92 moves to the initial end, the electromagnetic suction cup 96 moves to the vertical state. When the conveyor belt mechanism 12 is moved to the top, the distance sensor 15 at this position is sensed, causing the conveyor belt mechanism 12 to operate, and the U-shaped hanging ring on the conveyor belt mechanism 12 is transported to the bottom of the electromagnetic suction cup 96. Then the electromagnetic suction cup 96 is powered on and started, and the cylinder 91 extends to move the U-shaped hanging ring on the electromagnetic suction cup 96 to the placement plate 5. At this time, the distance sensor 15 at the end of the fixed plate 13 is sensed, causing the clamping assembly 7 to clamp the U-shaped hanging ring on the electromagnetic suction cup 96. After the clamping is fixed, the electromagnetic suction cup 96 is powered off, and the cylinder 91 is recovered to proceed to the next cycle. The overall operation is highly automated, which improves the automation and accuracy of the handling process.

[0026] In this embodiment, if Figures 8 to 11As shown, the clamping assembly 7 includes two second sliders 72, which are relatively slidably arranged on the placement plate 5, and the two second sliders 72 are fixedly mounted with a clamping plate 73. The placement plate 5 is provided with a second slide groove 75 for the second slider 72 to slide, and a double-headed screw 74, which is rotatably arranged on the placement plate 5. The two second sliders 72 are sleeved and threadedly connected to the two ends of the double-headed screw 74. A motor 71 that drives the double-headed screw 74 to rotate is fixedly mounted on the placement plate 5. Multiple groups of placement plates 5 are provided with auxiliary positioning assemblies 16, and the auxiliary positioning assemblies 16 include an auxiliary plate 161, which is vertically slidably arranged on the placement plate 5 between the two clamping plates 73, and a movable plate 163, which is movably arranged In the turntable 3, a movable groove 165 for the movable plate 163 is provided in the turntable 3, and a first spring 164 is provided in the movable groove 165 to resist the movable plate 163. The movable rod 162, whose two ends are respectively fixedly connected to the movable plate 163 and the auxiliary plate 161, is provided with an anti-deflection block 18 for sliding on the clamping plate 73, and a movable groove 19 for the anti-deflection block 18 to move is provided on the clamping plate 73. A second spring 21 is provided in the movable groove 19 to resist the anti-deflection block 18, and two third sliders 20 are relatively fixedly installed on the anti-deflection block 18. A third slide groove 22 for the third slider 20 to slide is provided in the clamping plate 73, and the third slide groove 22 is connected to the movable groove 19. The second spring 21 is located at the third In the slide groove 22, specifically, when the electromagnetic suction cup 96 adsorbs the U-shaped hanging ring onto the placement plate 5, the U-shaped hanging ring is located between the two clamping plates 73, the electromagnetic suction cup 96 is located at the top of the U-shaped hanging ring, and the clamping plate 73 is relative to the bottom of the U-shaped hanging ring. When the U-shaped hanging ring on the placement plate 5 is clamped, the motor 71 drives the double-headed screw 74 to rotate. Since the two second sliders 72 are threadedly connected to the double-headed screw 74, and the placement plate 5 has a second slide groove 75 to limit its movement direction, the two second sliders 72 will slide relative to each other, driving the clamping plate 73 to clamp the power fittings, so that the position of the clamping plate 73 can be automatically adjusted according to the size of the U-shaped hanging ring, so that U-shaped hanging rings of different specifications can be clamped. The stable clamping of the hanging ring improves the versatility and accuracy of the detection. At this time, the auxiliary positioning assembly 16 and the anti-deflection block 18 play an auxiliary positioning role, effectively preventing the electrical hardware from deflecting during the clamping process, improving the stability and accuracy of the clamping, and thus improving the accuracy of the strength detection; when the pressure detection device 6 applies pressure to the U-shaped hanging ring, the auxiliary plate 161 will be squeezed by the pressure detection device 6 and slide vertically, and the movable plate 163 is driven by the movable rod 162 to move in the movable groove 165 of the turntable 3, compressing the first spring 164, and at the same time the anti-deflection block 18 will also slide downward and squeeze the second spring 21 to facilitate the normal operation of the pressure detection device 6.

[0027] It should be noted that, in this embodiment, the structure of the pressure detection device 6 can refer to Figures 1 to 4As shown, it includes a support frame, a telescopic rod mechanism (electric telescopic rod, cylinder, etc.), a pressure plate, etc. The structure and working principle of the pressure detection device 6 are existing technologies, and reference can be made to the pressure testing machine in the existing technology.

[0028] In this embodiment, if Figures 1 to 8 As shown, support plates 17 are fixedly installed on multiple placement plates 5, and supporting blocks 23 for supporting the support plates 17 are fixedly installed on the testing platform 2 adjacent to the pressure testing device 6. Specifically, when the turntable 3 rotates to the position of the pressure testing device 6, the support plates 17 on the placement plates 5 will be supported by the supporting blocks 23 adjacent to the testing platform 2, providing additional support for the placement plates 5 and the electrical hardware, so that the pressure testing device 6 can more accurately apply pressure to the electrical hardware and detect its strength, thereby improving the stability of the electrical hardware during the detection process, avoiding the accuracy of the detection results affected by the shaking of the placement plates 5 or the electrical hardware, and ensuring the reliability of the pressure detection.

[0029] Working principle: During operation, the U-shaped hanging ring moves with the conveyor belt mechanism 12 to the specified position below the fixed plate 13, and the sliding plate 92 is located on the side of the fixed plate 13 close to the conveyor belt. At this time, the slide bar 94 is in the first horizontal section 951 (higher height) of the slide rail 95, and the lifting plate 93 drives the electromagnetic suction cup 96 to contact the U-shaped hanging ring on the conveyor belt mechanism 12. The electromagnetic suction cup 96 is energized to generate magnetic force, which adsorbs the hardware to the bottom of the electromagnetic suction cup 96 to ensure that the hardware can stably take out the material. Then, the controller 10 controls the cylinder 91 to push the sliding plate 92 to slide toward the placement plate 5, and the sliding rod 94 slides along the first horizontal section 951 to the connection between the lifting section 952, and the sliding rod 94 enters the lifting section 952. Since the height of the first horizontal section 951 is higher than that of the second horizontal section 953, the sliding rod 94 slides down along the inclined track, driving the lifting plate 93 to move downward, and the sliding rod 94 slides into the second horizontal section 953 (lower in height) along the lifting section 952. At this time, the lifting plate 93 is in a low position. During this process, when the first slider 81 slides on the fixed plate 13, the second connecting rod 83 is driven to rotate through the first connecting rod 82. The rotation of the second connecting rod 83 causes the second bevel gear 88 to rotate, and the second bevel gear 88 is engaged with the first bevel gear 87, thereby driving the rotating plate 84 to rotate around the third rotating shaft 86 to adjust the position of the electromagnetic suction cup 96. When the sliding rod 94 moves to the end of the second horizontal section 953, the rotating plate 84 rotates 90 degrees, so that the U-shaped hanging ring on the electromagnetic suction cup 96 is rotated from a lying state to a vertical state. The U-shaped hanging ring is in the state, and the U-shaped hanging ring moves to the placement plate 5 and is located in the clamping groove of the clamping assembly 7. The controller 10 controls the clamping assembly 7 on the placement plate 5 to clamp the U-shaped hanging ring to ensure that the hardware position is stable during detection. Then the electromagnetic suction cup 96 is powered off, and the U-shaped hanging ring loses its magnetic adsorption. The controller 10 controls the cylinder 91 to reversely drive the sliding plate 92 to move toward the fixed plate 13, and the slide bar 94 enters the second horizontal section 953 from the second horizontal section 953 through the lifting section 952 to the second horizontal section 953, so that the electromagnetic suction cup 96 moves again to the top of the conveyor belt mechanism 12 to adsorb the U-shaped hanging ring thereon. Afterwards, the groove wheel mechanism at the bottom of the detection platform 2 is controlled by the controller 10 to drive the first rotating shaft 4 to rotate intermittently, and each time it rotates an angle, the placement The plate 5 (with hardware placed on it) is transferred to the bottom of the pressure detection device 6. The pressure detection device 6 applies pressure to the U-shaped hanging ring, collects data through the force sensor and displacement sensor, and completes the strength detection. After the detection, the detected motor 71 hardware is moved to the unloading position through the groove wheel intermittent drive mechanism 11, and then the above steps can be repeated, so that the handling component 9 continues to take and discharge materials, and the turntable 3 rotates intermittently to realize continuous detection of multi-station hardware. The overall structure has simple operating steps and a high degree of automation, which realizes automatic handling and intermittent detection of electrical hardware, improves detection efficiency, reduces manual operation, and reduces labor intensity. At the same time, the clamping component 7 and the pressure detection device 6 can more accurately perform strength detection on the electrical hardware.
