Description

Technical Field

[0001] This utility model relates to the field of insulating bolt testing technology, specifically a device for testing the preload of detachable insulating bolts. Background Technology

[0002] Insulating bolts, with their excellent insulation properties and fastening effect, are widely used in electrical equipment, power engineering, electromechanical and other scenarios requiring insulation protection. However, bolts are prone to preload loss during long-term use, necessitating regular preload testing to ensure safe equipment operation. The diverse specifications of insulating bolts place higher demands on the adaptability and ease of operation of testing devices.

[0003] Currently, in the prior art, for example, Chinese patent with publication number CN216899390U discloses a detachable bolt preload detection device. This device calculates the bolt preload through sensor signal output and then obtains the bolt preload value. However, this device can only be adapted to a single specification of insulating bolt. When testing bolts of different specifications, the entire set of adapter components needs to be replaced, which is cumbersome and time-consuming. In view of this, we propose a detachable insulating bolt preload detection device. Utility Model Content

[0004] The main objective of this invention is to provide a detachable insulating bolt preload detection device that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a detachable insulating bolt preload testing device, comprising a testing device and a mounting base. The bottom of the testing device is fixedly connected to the top of the mounting base. The mounting base has a fixing hole, and a partition frame is fixedly connected to the top of the mounting base. A quick-change assembly is provided on the partition frame, and the quick-change assembly includes: A ring rail is fixedly connected to the top of the partition frame, and a mounting turntable is slidably connected to the top of the ring rail; Mounting hole: The mounting turntable has a mounting hole, and a threaded sleeve is threadedly connected to the mounting hole; A hexagonal through block is welded to the top of the threaded sleeve, and a standard hole is opened on the threaded sleeve.

[0006] Preferably, there are six sets of mounting holes, which are threaded through holes, evenly distributed on the mounting turntable, and the thread specifications are uniform.

[0007] Preferably, the outer wall of the threaded sleeve is provided with threads, the hexagonal through block is provided with a hexagonal through groove, the specification hole is a threaded through hole, and an insulating bolt is threadedly connected to the specification hole. The specification hole on different threaded sleeves has a different size.

[0008] Preferably, a step bar is fixedly connected to the top of the partition frame, and the outer wall of the step bar is threaded, with the step bar being tapered at the top and tapered at the bottom.

[0009] Preferably, the outer wall of the stepped bar is threaded with a first limiting ring, which is threaded to the coarse end of the stepped bar.

[0010] Preferably, a positioning plate is sleeved at the step of the step bar, and a second limiting ring is threadedly connected to the outer wall of the step bar. The second limiting ring is located at the top of the positioning plate and is threadedly connected to the thin end of the step bar.

[0011] Preferably, the positioning plate has a through hole, the mounting turntable has a directional hole, a directional rod is inserted into the through hole, and there are six sets of directional holes.

[0012] This utility model provides a device for detecting the preload force of detachable insulating bolts. It has the following advantages: (1) The detachable insulating bolt preload testing device has a fast and convenient specification switching function and strong adaptability. By rotating the mounting turntable, threaded sleeves with different hole specifications can be quickly switched to the top of the testing device without disassembling the entire quick-change assembly, which can adapt to insulating bolts of different specifications, greatly shortening the specification change time and improving testing efficiency; the directional insert and directional hole can achieve precise positioning of the threaded sleeve, ensuring stability during testing and further improving the flexibility of the device.

[0013] (2) The threaded sleeve of the detachable insulating bolt preload testing device is easy to assemble and disassemble and has good expandability. By using a wrench to rotate the hexagonal plug, the threaded sleeve can be quickly unscrewed from the mounting hole of the mounting turntable. The operation process is simple and does not require complicated tools. When the existing specification hole cannot meet the testing requirements, the corresponding specification threaded sleeve can be replaced separately without replacing the entire device, which effectively expands the device's adaptability range to insulating bolts of different specifications.

This utility model does not improve its own structure, but only realizes the preload testing of the insulated bolt 13 by cooperating with the testing device 1 through the quick-change component 5. Therefore, the detailed structure and working process of the testing device 1 will not be described in detail. The mounting base 2 has fixing holes 3. The mounting base 2 is a metal plate with a flat surface. It is fixed to the external structure through the fixing holes 3 to provide stable support for the overall device. The top of the mounting base 2 is fixedly connected to... There is a separator frame 4, and a quick-change assembly 5 is provided on the separator frame 4. The quick-change assembly 5 includes a ring rail 51. The ring rail 51 is fixedly connected to the top of the separator frame 4. The top of the ring rail 51 is slidably connected to the mounting turntable 52. The mounting turntable 52 is a circular metal disc with an annular groove at the bottom that matches the ring rail 51. It can rotate 360°. The mounting turntable 52 has a mounting hole 53. A threaded sleeve 54 is threadedly connected to the mounting hole 53. A hexagonal through block 55 is welded to the top of the threaded sleeve 54. The hexagonal through block 55 is a regular hexagonal metal block, which is convenient to rotate with a wrench, saves effort and is not easy to slip. The threaded sleeve 54 has a specification hole 56. The specification hole 56 on different threaded sleeves 54 is of different sizes, so as to facilitate the adaptation of different specifications of insulating bolts 13.

[0020] In this utility model, six sets of mounting holes 53 are provided. The mounting holes 53 are threaded through holes and are evenly distributed on the mounting turntable 52. The thread specifications are uniform and they are adapted to the installation of threaded sleeves 54. The outer wall of the threaded sleeve 54 is provided with threads.

According to the specifications of the insulating bolt 13 to be tested, pull out the directional plug 12, rotate the installation turntable 52 to align the threaded sleeve 54 of the corresponding specification hole 56 with the testing device 1, and reinsert the directional plug 12 to complete the positioning. Screw the insulating bolt 13 into the specification hole 56 so that the insulating bolt 13 passes through the specification hole 56 and enters the testing device 1, so that the testing device 1 can perform preload force testing. When it is necessary to replace the insulating bolt 13 with another specification, simply repeat the above rotation switching steps. If the existing threaded sleeve 54 does not have a corresponding specification, you can use a wrench to rotate the hexagonal plug 55 to unscrew the original threaded sleeve 54 from the mounting hole 53, and screw the new specification threaded sleeve 54 into the mounting hole 53. After the replacement is completed, you can continue the test.
