Description

Technical Field

[0001] The present invention relates to the technical field of insulator detection, and in particular to a multi-dimensional torque detection device for a columnar insulator. Background Art

[0002] The field of insulator testing technology involves the core issues of condition monitoring and defect identification of insulators in power equipment, including the detection of cracks, contamination, and mechanical damage to prevent power system failures. This field systematically integrates multiple testing methods, such as visual inspection, ultrasonic testing, and electrical performance evaluation, covering the entire process from on-site inspection to laboratory analysis. Among them, traditional multi-dimensional torque testing equipment for column insulators refers to technical issues aimed at evaluating the mechanical strength and durability of column insulators under multi-directional torque. Traditionally, this type of equipment uses a servo motor to drive a rotating shaft to apply torque, a fixture to fix the insulator sample, and a strain gauge or torque sensor to measure the torque response data. Mechanical linkage mechanisms are used to simulate multi-dimensional load conditions.

[0003] Chinese patent publication number CN207020014U discloses an insulator bending and torsion testing device, including a mobile trolley and an electric control cabinet and a hydraulic system arranged on the mobile trolley. The hydraulic system includes an oil tank, a motor, a gear pump, a one-way valve, a proportional relief valve, a first electromagnetic reversing valve, a bending measuring cylinder, a quick-change joint, a torque measuring cylinder, and an air cooler. The motor is connected to the gear pump, the input end of the gear pump is connected to the oil tank, the output end of the gear pump is connected to the one-way valve and the first electromagnetic reversing valve in sequence, the oil inlet of the proportional relief valve is connected to the oil outlet of the one-way valve, and the oil outlet of the proportional relief valve is connected to the oil tank through an air cooler. When the bending force or torsion of the insulator needs to be tested, the side bending cylinder, the torque measuring cylinder and the first reversing solenoid valve are converted by the quick-change joint to achieve connection, and the first electromagnetic reversing valve is connected to the oil tank through an air cooler.

[0004] Existing technologies rely on a hydraulic system to drive the cylinder to apply bending and torsional forces, and require manual operation of a quick-change connector to switch test modes. The hydraulic response has an inherent delay, resulting in a slow testing process and cumbersome and time-consuming switching steps. The fixing fixture lacks adaptive adjustment capabilities and cannot adapt to different insulator shapes or sizes. When simulating multi-dimensional loads or rapidly changing conditions such as radial sway caused by strong winds, the displacement control accuracy is insufficient, which may affect the accuracy of the test results, increase the risk of missed detection, and reduce the overall reliability of the system.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] Example 1, a multi-dimensional torque detection device for a column insulator, see Figure 1 and Figure 2 , including a bracket 1, the upper end of the bracket 1 is fixedly connected to the shell 2, the front end of the shell 2 is symmetrically rotated with an isolation plate 21, the front end of the upper end of the bracket 1 is fixedly connected to the control end 3, the top wall of the inner surface of the shell 2 is provided with a bending detection structure 5, the lower part of the inner surface of the shell 2 is fixedly connected to the rotation detection structure 4, and the upper part of the inner surface of the shell 2 is arc-shaped.

[0034] During the operation of this embodiment, the insulator is clamped and fixed by the rotation detection structure 4 arranged on the inner surface of the shell 2, and the upper part of the insulator is limited in cooperation with the bending detection structure 5. The rotation detection structure 4 is driven by the motor to rotate and the contact sensor and torque sensor arranged in the rotation detection structure 4 and the bending detection structure 5 are coordinated to monitor the torque data. The torsional performance of the insulator is further detected by the cooperation of the bending detection structure 5 and the rotation detection structure 4, thereby realizing multi-dimensional detection of the insulator performance and improving the detection efficiency.

[0035] Embodiment 2: Based on Embodiment 1, this embodiment further achieves clamping and fixing of the upper side of the insulator and detection of the radial torque of the insulator. Specifically, the curved guide rail 51 of the bending detection structure 5 cooperates with the traction rope 52 to drive the roller 53 to drive the second limit plate 54 and the connecting assembly 55 along a predetermined arc trajectory. The limit rod 541 on the second limit plate 54 cooperates with the second compression spring 542 to form an automatic correction mechanism, ensuring that the connecting assembly 55 moves accurately along the axis of the guide rail 51 and maintains trajectory accuracy. The electric telescopic rod 553 of the connecting assembly 55 drives the L-shaped connecting rod 552 and the clamping component 554. In combination with the spring plate 5541, rack 5544, gear 5543 and clamping plate 5542 of the clamping component 554, a three-point adaptive and stable clamping of the upper end of the insulator is achieved. Finally, through the synchronous coordination of the above-mentioned mechanism and the rotation detection structure 4, a controllable radial displacement is applied to the upper end of the insulator, accurately simulating the radial shaking caused by strong winds, effectively detecting the mechanical properties of the insulator against radial bending / twisting, and monitoring the feedback data in real time.

[0036] For details, see Figure 3 The bending detection structure 5 includes a curved guide rail 51 opened on the top wall of the inner surface of the shell 2. The curved guide rail 51 is an arc-shaped track. The outer arc surface of the curved guide rail 51 is slidably connected to a traction rope 52 driven by an electric winch. The outer surface of the traction rope 52 and the inner surface of the curved guide rail 51 are slidably connected to a roller 53. The lower end of the roller 53 is rotatably connected to a limit plate 2 54 that is in contact with the top wall of the inner surface of the shell 2. The lower end of the limit plate 2 54 is fixedly connected to a connecting component 55.

[0037] During the test, the bottom of the insulator is supported by the rotation detection structure 4, and the top of the insulator is limited by the connection component 55. During the rotation of the rotation detection structure 4, the connection component 55 limits the rotation of the other side of the insulator, and the torsional bearing parameters of the insulator are tested by twisting one end.

[0038] A sensor array for detection is installed in both the connecting component 55 and the rotation detection structure 4, which is used to respond after fracture or collapse and transmit data to the control terminal 3. The installation and monitoring methods of the sensors are conventional means in the prior art. It should be further explained that the control terminal 3 is also a conventional control device in the prior art, which is used to control the start and stop, operating data and operating status of the motor, and can further receive signals from the sensor array and convert and output detection results. This process is a mature technical means in the prior art and will not be elaborated and demonstrated in detail in the present invention.

[0039] The traction rope 52 is controlled by the electric winch. During the rotation of the winch, the traction rope 52 will be pulled to move along the curved guide rail 51. The action of the traction rope 52 on the roller 53 can drive the roller 53 to slide in the curved guide rail 51, and then drive the limit plate 2 54 to slide on the inner wall of the shell 2.

[0040] For further information, see Figure 4 The lower end of the limiting plate 54 is rectangularly distributed and slidably connected to several limiting rods 541. The upper ends of the four limiting rods 541 all pass through the lower end of the limiting plate 54 and extend to the upper end of the limiting plate 54 and fit with the inner wall of the shell 2 through the pulley. The lower end of the limiting plate 54 is rectangularly distributed and fixedly connected to the compression spring 2 542 which is sleeved on the outer surface of the adjacent limiting rod 541. The compression springs 542 on both sides are inclined and their directions are both toward the center of the arc surface of the inner wall of the shell 2.

[0041] Since the roller 53 is rotating, position deviation will occur in the process of it sliding in the curved guide rail 51 driven by the traction rope 52. The limit rod 541 installed on the limit plate 2 54 can always fit inside the shell 2 under the action of the compression spring 2 542, and the limit plate 2 54 is always kept on the inner arc of the shell 2 through the action of the limit rods 541 on both sides, so that the connecting component 55 at the bottom of the limit plate 2 54 can always be on the axial center line of the curved guide rail 51 path, so that the connecting component 55 can drive the insulator to gradually twist along the arc path defined by the curved guide rail 51, thereby simulating the radial shaking caused by strong winds, and thus testing the radial twisting performance of the insulator.

[0042] For further information, see Figure 5The connecting assembly 55 includes a connecting plate 551 fixedly connected to the lower end of the limit plate 2 54, a contact plate 555 is slidably connected to the lower end of the connecting plate 551, and a compression spring 3 556 is fixedly connected to the inner cavity of the connecting plate 551 on the upper end of the contact plate 555. The lower end of the connecting plate 551 is symmetrically slidably connected to the L-shaped connecting rod 552, and the inner cavity of the connecting plate 551 is symmetrically fixedly installed with an electric telescopic rod 553. The piston rods of the two electric telescopic rods 553 are respectively fixedly connected to the vertical parts of the adjacent L-shaped connecting rods 552, and the ends of the horizontal parts of the two L-shaped connecting rods 552 that are close to each other are each provided with a clamping component 554.

[0043] After the rotation detection structure 4 fixes the lower end of the insulator, it is necessary to fix the upper end of the insulator synchronously and limit the insulator when the control end 3 rotates, thereby realizing the torque detection of the insulator;

[0044] The fixed insulator is pushed upward by the rotation detection structure 4 until the upper end of the insulator contacts the contact plate 555. A contact sensor is installed at the lower part of the contact plate 555. After the sensor responds to pressure, the control terminal 3 controls the electric telescopic rod 553 to retract and drives the clamping part 554 to approach the two sides of the insulator through the L-shaped connecting rod 552 until the clamping part 554 contacts the edge of the insulator. The insulator is gradually clamped and limited, which facilitates subsequent testing.

[0045] Furthermore, the insulator can be rotated to different angles using the rotation detection structure 4 and then fixed and bent through the connection assembly 55, thereby enabling detection of torsional performance at different angles and improving the use range and detection range of the device.

[0046] For further information, see Figure 6 The clamping component 554 includes a spring plate 5541 provided at one end of the horizontal part of the L-shaped connecting rod 552 close to the contact plate 555, and the end of the spring plate 5541 close to the L-shaped connecting rod 552 is symmetrically fixedly connected to the rack 5544 that is slidingly connected to the L-shaped connecting rod 552. The horizontal part of the L-shaped connecting rod 552 is symmetrically connected to the splint 5542 for rotation front and back, and the two splints 5542 are fixedly connected to the rotating axis of the L-shaped connecting rod 552 with a gear 5543 that meshes with the rack 5544.

[0047] The spring plate 5541 is located on the end face of the horizontal part of the L-shaped connecting rod 552. When the L-shaped connecting rod 552 approaches the insulator, the spring on the spring plate 5541 will be gradually compressed. Synchronously, the rack 5544 follows the spring plate 5541 and moves relative to the gear 5543. Under the meshing action of the spring plate 5541 and the gear 5543, the clamping plate 5542 is driven to rotate relative to the L-shaped connecting rod 552 toward the insulator until it is completely fitted to the adjacent surface of the insulator. At this time, the clamping plate 5542 is relatively restricted from moving, and the spring plate 5541 and the clamping plate 5542 cooperate with the contact plate 555 to clamp and fix the upper end of the insulator.

[0048] Embodiment 3: Based on embodiment 2, this embodiment further realizes the clamping and fixing of the lower part of the insulator and the detection of the circumferential torque of the insulator. Specifically, the telescopic seat 41 of the rotation detection structure 4 cooperates with the U-shaped base 42 to realize the lifting and positioning of the lower part of the insulator; through the cooperation of the rotating disk 431, the wedge block 1 433, the sliding rod 434 and the limit plate 1 432 of the clamping drive member 43, the sliding rod 434 is driven to move centripetally to clamp the outer side of the insulator when the rotating disk 431 is rotated, and the arc groove 421 and the limit plate 1 432 are used to realize one-way locking; through the cooperation of the wedge block 2 4232, the top rod 4233, the support block 4234 of the inner support assembly 423 and the linkage rod 436 of the rotating disk 431, the support block 4234 is synchronously pushed to expand radially when the rotating disk 431 rotates, thereby realizing synchronous internal support and fixation of the inner wall of the insulator. Finally, through the rotational drive of the telescopic seat 41 and the fixed limit of the upper end connecting assembly 55, the lower end of the insulator is subjected to a controllable circumferential torsional load, effectively completing the performance test of the insulator's resistance to circumferential torsion.

[0049] For further information, see Figure 7 The rotation detection structure 4 includes a telescopic seat 41 rotatably mounted on the bottom wall of the inner surface of the shell 2. The telescopic seat 41 is driven to rotate by a motor installed at the lower end of the shell 2. The piston rod at the output end of the telescopic seat 41 is fixedly connected to a U-shaped base 42, and a clamping drive member 43 is provided on the outer surface of the U-shaped base 42.

[0050] During the testing process, the lower end of the insulator is clamped and fixed by the U-shaped base 42 and the clamping drive 43, and the fixed insulator is pushed upward by the action of the telescopic seat 41 so that it enters the range of the connecting component 55. After both sides of the insulator are fixed, the motor at the bottom of the telescopic seat 41 is further used to drive the insulator to rotate. Since the upper end of the insulator is fixed by the connecting component 55, the insulator will be subjected to circumferential torsional force during the process of the telescopic seat 41 driving the U-shaped base 42 and the clamping drive 43 to rotate, thereby realizing the torsional bearing performance test of the insulator.

[0051] For further information, see Figure 8and Figure 9 The outer surface of the U-shaped base 42 is provided with a plurality of arc grooves 421 that engage with the clamping drive member 43, and the middle part of the upper end of the U-shaped base 42 is provided with a plurality of spring grooves 422 distributed in a ring shape. The inner surfaces of the plurality of spring grooves 422 and the middle part of the upper end of the U-shaped base 42 are jointly provided with an internal support component 423.

[0052] The inner wall of the insulator is supported and fixed by the inner support assembly 423 to prevent the insulator from being separated from the U-shaped base 42 during the rotation process, thereby affecting the detection result.

[0053] For further information, see Figure 10 The clamping drive member 43 includes a rotating disk 431 sleeved on the outer surface of the U-shaped base 42, and the inner surface of the rotating disk 431 located in the inner cavity of the U-shaped base 42 is fixedly connected to a number of wedge blocks 433 distributed in an annular manner, and the inner cavity of the U-shaped base 42 is fixedly connected to a number of sliding rods 434 that are closely attached to the inclined surface of the wedge block 433. The several sliding rods 434 all penetrate the inner cavity of the U-shaped base 42 and extend to the inner surface of the U-shaped base 42. The inner surface of the sliding rod 434 located in the inner cavity of the U-shaped base 42 is fixedly connected to a compression spring 435 fixedly connected to the inner cavity of the U-shaped base 42. The outer surface of the rotating disk 431 is slidably connected to a limit plate 432 that is buckled with the adjacent arc groove 421 through a spring.

[0054] Specifically, after placing the insulator on the upper part of the U-shaped base 42, the rotating disk 431 is rotated forward, and the sliding rod 434 is pushed toward the inner side of the U-shaped base 42, that is, the outer edge of the insulator through the action of the wedge block 1 433 inside the rotating disk 431. At this time, when the limit plate 1 432 moves in the forward direction, it can slide freely in the arc groove 421 until the sliding rod 434 is completely in contact with the outer surface of the insulator to clamp and fix the insulator. At the same time, only one side of the inner side of the arc groove 421 is arc-shaped, and the other side is a vertical surface, so it will restrict the limit plate 1 432 to prevent the rotating disk 431 from rotating in the opposite direction.

[0055] If the insulator needs to be released, the limiting plate 432 is pulled to separate it from the arc groove 421. At this time, the rotating disk 431 can rotate freely in the reverse direction to release the insulator.

[0056] For further information, see Figure 11The inner support assembly 423 includes a support block 4234 that is slidably connected to the inner surface of the adjacent spring groove 422, the bottom wall of the inner surface of the U-shaped base 42 is rotatably connected to the center disk 4231, and the inner surface of the center disk 4231 is annularly distributed and fixedly connected with a number of wedge-shaped blocks 4232, and the inner surfaces of the several spring grooves 422 are slidably connected with a number of top rods 4233 that fit the inclined surfaces of the adjacent wedge blocks 4232, and the several top rods 4233 are all fixedly connected to the lower ends of the adjacent support blocks 4234, and a linkage rod 436 is fixedly connected at the axis of the center disk 4231, and the end of the linkage rod 436 away from the center disk 4231 is fixedly connected to the lower end of the rotating disk 431, and the inner cavity of the U-shaped base 42 is provided with a fan-shaped groove for the sliding of the linkage rod 436.

[0057] Since the rotating disk 431 and the inner support assembly 423 are concentric, during the rotation of the rotating disk 431, the center disk 4231 can be synchronously driven to rotate through the linkage rod 436. At the same time, due to the concentricity, their angular velocities are the same. During the rotation of the center disk 4231, the wedge block 4232 will push the top rod 4233 to diffuse and move outward. At the same time, since the top rod 4233 and the support block 4234 are connected together, the support block 4234 can be pushed to diffuse and move outward, and then supported and fixed from the inner wall of the insulator, further ensuring the fixation of the insulator, improving its stability during the detection process, and reducing the impact on the detection results.
