DETAILED DESCRIPTION

[0024] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, an insulator size measuring platform includes a frame 1 and a clamp 2 for installing an insulator 9. The frame 1 is provided with a fastening guide sleeve 3 connected to the clamp 2, and a tensioning mechanism 4 for tightening the insulator 9 and the clamp 2. The fastening guide sleeve 3 is detachably mounted on the tensioning mechanism 4. The frame 1 is also provided with a tensioning sensing module 5 for detecting the tensioning of the tensioning mechanism 4. The frame 1 is also provided with a rotating transmission assembly 6 for driving the clamp 2 to rotate. The frame 1 is also provided with a displacement measurement system 7.

[0025] The insulator 9 is quickly mounted on the fastening guide sleeve 3 by the clamp 2, and is mounted on the frame 1 along with the fastening guide sleeve 3, and then the tightening function between the insulator 9 and the clamp 2 is realized by the tightening mechanism 4, thereby ensuring the reliability of the fixation of the insulator 9 during the test, and the height measurement can be completed at the same time after tightening. Secondly, the fastening guide sleeve 3 does not need to be repeatedly positioned. For each measurement of the insulator 9 of the same specification, the fastening guide sleeve 3 can be clamped and adjusted once, and no repeated calibration is required subsequently. The test repeatability is high. The clamp 2 is driven to rotate by the rotating transmission component 6, which can ensure that the insulator 9 under test rotates clockwise along the axis, smoothly and at a uniform speed, thereby ensuring the reliability of the measurement. The setting of the displacement measurement system 7 can quickly realize the detection of the insulator 9, so that the entire measuring platform can simultaneously meet the measurement of structural height and axial and radial dimensional offsets. The overall installation and disassembly is convenient, the use is simple, and the height positioning is precise.

[0026] The tensioning mechanism 4 includes a bearing mounting seat 41, a stepper drive motor rod 42 and a support base 43. The bottom end of the stepper drive motor rod 42 is mounted on the support base 43, and the top end of the stepper drive motor rod 42 is arranged on the bearing mounting seat 41. The fastening guide sleeve 3 is mounted on the bearing mounting seat 41 through a positioning mechanism 8. The tensioning sensing module 5 is arranged on the support base 43. The support base 43 is provided with a pull wire sensor 44. The tensioning mechanism 4 is set to a structure of a bearing mounting seat 41, a stepper drive motor rod 42 and a support base 43. Secondly, the bearing mounting seat 41 is used to install a plane bearing. When the insulator 9 is tightened, the friction resistance can also be reduced to ensure the stable rotation of the insulator 9. The support base 43 provides sufficient rigidity and strength to ensure that the components installed thereon have a stable bracket 12. The pull wire sensor 44 is an extremely accurate and easy to calibrate length measurement sensor 44. In this embodiment, it is mainly used to measure the structural height of the insulator 9.

[0027] The positioning mechanism 8 includes a buckle 81 and a slot 82. The buckle 81 is arranged on the outer side wall of the guide sleeve 3, and the slot 82 is arranged on the bearing mounting seat 41. The slot 82 includes a vertical portion 83 and a horizontal portion 84. The horizontal portion 84 is arranged at the bottom end of the vertical portion 83. The buckle 81 passes through the vertical portion 83 and is fixedly connected to the horizontal portion 84. The positioning mechanism 8 is arranged into a structure of a buckle 81 and a slot 82. When the insulator 9 needs to be replaced, the buckle 81 only needs to be turned out of the slot 82 to remove the clamp 2, thereby conveniently replacing the insulator 9. Secondly, the slot 82 is arranged into a structure of a vertical portion 83 and a horizontal portion 84, which can prevent the buckle 81 from being prevented from coming out.

[0028] The tensioning sensing module 5 includes a stop shaft 51, a compression spring 52 and a movable plate 53. The stop shaft 51 is arranged on the support base 43, and the movable plate 53 is arranged at the bottom end of the stop shaft 51. The compression spring 52 is sleeved on the stop shaft 51, and one end of the compression spring 52 is in contact with the support base 43, and the other end of the compression spring 52 is in contact with the movable plate 53. A proximity switch 11 for sensing the position of the movable plate 53 is provided on the frame 1. The proximity switch 11 is connected to the stepping drive motor rod 42. When the tension generated by the electric rod tightening the insulator 9 is greater than the spring force, the spring is compressed, the relative distance is shortened, and the movable plate 53 is in the position. The position of the movable plate 53 changes, that is, when a certain force is applied, the proximity switch 11 senses the position of the movable plate 53, that is, a tensioning signal is issued, and the electric push rod stops moving. This action is regarded as a tensioned state. The frame 1 is provided with a bracket 12 for fixing the proximity switch 11. The bracket 12 is installed on the frame 1 by screws, which can realize the rapid installation and fixation of the proximity switch 11. The screws facilitate the rapid positioning of the bracket 12 on the frame 1. In addition, in order to improve the installation efficiency of the bracket 12, the bracket 12 in this embodiment includes a horizontal plate and a vertical plate. The horizontal plate is arranged at the bottom end of the vertical plate. The horizontal plate is provided with a strip hole for installing screws, and the proximity switch 11 is installed on the vertical plate.

[0029] The displacement measuring system 7 includes an axial deviation measuring dial indicator 71 and a radial deviation measuring dial indicator 72. The frame 1 is provided with a hydraulic locking dial seat 13 for fixing the axial deviation measuring dial indicator 71 and the radial deviation measuring dial indicator 72 respectively. When the insulator 9 makes a circular motion, the axial deviation measuring dial indicator 71 is used to measure the axial displacement deviation of the insulator 9, and the radial deviation measuring dial indicator 72 is used to measure the radial displacement deviation of the insulator 9, ensuring the reliability of data acquisition. The clamp 2 includes an upper connecting member 21 and a lower connecting member 22. The lower connecting member 22 is arranged on the fastening guide sleeve 3, and the upper connecting member 21 is arranged on the rotating transmission assembly 6, and the vertical axis of the upper connecting member 21 coincides with the vertical axis of the lower connecting member 22, so that the insulator 9 can be quickly installed on the frame 1, the installation and disassembly are convenient, the connection is reliable, and the rotation stability of the insulator 9 is ensured.

[0030] The rotary transmission assembly 6 includes a fixed seat 61, a bearing seat 62 and a synchronous belt 63 arranged on the fixed seat 61 and the bearing seat 62. The frame 1 is provided with a stepper motor 14 connected to the bearing seat 62, and the upper connecting member 21 is installed on the fixed seat 61. The frame 1 is provided with a tensioning bolt 15 for adjusting the tightness of the synchronous belt 63. The synchronous belt 63 is driven by the stepping motor 14 for transmission, with good driving effect and easy installation. In addition, in order to prevent the problem of jamming during the transmission process, the bearing seat 62 in this embodiment adopts an angular contact ball bearing seat. Since the angular contact ball bearing seat can withstand axial load and radial load at the same time, it can ensure that the axis of the rotary transmission assembly 6 is relatively perpendicular to the installation plane. The tightness of the synchronous belt 63 is adjusted by the tensioning bolt 15 to meet different test requirements.

[0031] The frame 1 includes a frame body 16 and support legs 17 arranged on the frame body 16. A horizontal cross plate 18 for installing the rotating transmission assembly 6 is provided at the top of the frame body 16, and the horizontal cross plate 18 and the frame body 16 are an integrated structure. The setting of the support legs 17 can serve as a reference support for the entire frame 1, ensure the horizontality of the measurement platform, and ensure the reliability of the test. In order to improve the strength and rigidity of the entire frame 1, the frame 1 in this embodiment is welded with industrial profiles. A guide seat 19 is also provided on the frame body 16. The tensioning mechanism 4 passes through the guide seat 19 and is connected to the fastening guide sleeve 3. The setting of the guide seat 19 can serve as a fixed hinge constraint for the tensioning mechanism 4, ensuring the stability and reliability of the tensioning mechanism 4.

Those skilled in the art can make various changes and modifications based on the present invention.
