Description

Technical Field

[0001] This utility model relates to the field of insulating sleeve technology, and more specifically, to an online thickness measuring device for insulating sleeves. Background Technology

[0002] Fiberglass bushings are primarily used as electrical insulation materials. They serve to prevent short circuits caused by small animals such as rats and snakes; prevent corrosion of busbars by acids, alkalis, and salts; prevent maintenance personnel from accidentally entering live areas and sustaining injuries; and adapt to the trend of miniaturization in switchgear, solving the phase-to-phase insulation problem of busbar trunking. After production, the wall thickness of fiberglass bushings often needs to be measured to verify their quality.

[0003] Existing wall thickness measuring instruments typically involve cutting the fiberglass insulation sleeve and placing it flat on the measuring plane. The wall thickness is then measured by an optical electronic probe. However, cutting the fiberglass insulation sleeve is usually done manually, which can easily lead to skewness in the cross-section. This results in the cut piece of the fiberglass insulation sleeve not being placed perpendicularly on the measuring plane, causing measurement errors.

[0004] A search revealed a Chinese patent with publication number CN219531998U that discloses a device for measuring the wall thickness of a fiberglass insulating sleeve. This utility model has the advantages of clamping and limiting the fiberglass insulating sleeve to ensure that it is perpendicular to the measuring plane and reducing measurement errors.

[0005] However, in actual use, the insulating sleeves of the above measuring devices include metal substrates and all-plastic materials. When clamping and testing insulating sleeves of different materials, the insulating sleeves will undergo certain deformations, which will affect the accuracy of the thickness measurement of the insulating sleeves in subsequent electromagnetic thickness measurement. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an online thickness measuring device for insulating sleeves to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An online thickness measuring device for insulating sleeves includes a base frame, a chassis fixedly connected to the top of the base frame, a bracket fixedly connected to the top of the base frame, a servo motor fixedly connected to the bottom of the base frame, and a deflection positioning mechanism provided on the top of the base frame. The deflection positioning mechanism includes a turntable, the bottom of which is rotatably connected to the top of the chassis, and the bottom of which is fixedly connected to the output end of the servo motor. Two outer shells are fixedly connected to the outer side of the turntable, a worm gear is rotatably connected to the inner side of each outer shell, a turbine meshes with one side of the worm gear, and a screw is fixedly connected to the inner side of the turbine. Two guide frames are fixedly connected to the top of the turntable, the inner side of each guide frame is rotatably connected to the outer side of the screw, a bracket is threadedly connected to the outer side of the screw, the bottom of the bracket is slidably connected to the inner side of each guide frame, a rotating rod is rotatably connected to the inner side of the bracket, the rotating rod has two threads on its outer side, a transmission frame is threadedly connected to the outer side of each thread, a spring is fixedly connected to the inner side of each transmission frame, a guide rod is fixedly connected to one side of each spring, and the outer side of the guide rod is slidably connected to the inner side of the transmission frame. A detection and adjustment mechanism is provided inside the bracket.

[0009] By adopting the above technical solution: the worm gear drives the turbine and screw, so that the two screws can move the second bracket in opposite directions, and the rotating rod and screw drive the two transmission frames, so that the two sets of transmission frames can clamp and position the two ends of the insulating sleeve. The servo motor drives the turntable to deflect the insulating sleeve, so that the insulating sleeve can be detected at multiple points.

[0010] As a further description of the above technical solution: a second spring is fixedly connected to the inner side of the guide rod, and a locking block is fixedly connected to both ends of the second spring. The outer side of the locking block is slidably connected to the inner side of the guide rod, and the outer side of the locking block is engaged with the inner side of the transmission frame. A plurality of third springs are fixedly connected to the inner side of the guide rod, and a push plate is fixedly connected to one side of the third spring. A clamping arm is fixedly connected to one end of the push plate, and the inner side of the clamping arm is rotatably connected to the outer side of the guide rod.

[0011] By adopting the above technical solution: the two pairs of springs push the locking blocks so that the locking blocks can engage with the inner side of the transmission frame, which can avoid the guide rod from causing a large squeezing force on the insulating sleeve. At the same time, the multiple springs push the three pairs of push plates and clamping arms so that the multiple clamping arms can deflect and clamp in opposite directions, avoiding deformation of the insulating sleeve during clamping.

[0012] As a further description of the above technical solution: the detection and adjustment mechanism includes an electric push rod, the outer side of which is fixedly connected to the inner side of the first bracket, a transmission frame two is fixedly connected to the top of the electric push rod, the outer side of the transmission frame two is slidably connected to the inner side of the first bracket, a bolt is inserted into the inner side of the transmission frame two, a rotating plate is rotatably connected to the outer side of the bolt, an electromagnetic sensor is fixedly connected to the inner side of the rotating plate, and a capacitive sensor is fixedly connected to the bottom of the bolt.

[0013] By adopting the above technical solution: bolts are used to position the deflecting plate, and electromagnetic sensors and capacitive sensors are used to perform electromagnetic detection on the top and sides of the insulating sleeve.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting up a deflection positioning mechanism, compared with the existing technology, the opposing movement of two brackets and two sets of transmission frames, combined with the staggered clamping of multiple sets of clamping arms, is used to clamp and position both ends of the insulating sleeve. By using the sliding of the guide rod inside the transmission frame, excessive pressure on the metal-based insulating sleeve and the all-plastic insulating sleeve can be avoided, so that different types of insulating sleeves can be stably positioned to maintain the stability and accuracy of subsequent testing.

[0016] 2. By setting up a detection and adjustment mechanism, compared with the existing technology, the electromagnetic sensor and the capacitive sensor are raised and lowered and deflected by the rotating plate. This allows the electromagnetic sensor to adjust the distance between the electromagnetic sensor and the insulating sleeve according to the metal substrate insulating sleeve and the all-plastic insulating sleeve, so that different types of insulating sleeves can maintain good wall thickness detection effect.

The outer side of guide rod 16 is slidably connected to the inner side of transmission frame 14. A detection and adjustment mechanism is set on the inner side of bracket 1 3. The servo motor 4 drives the turntable 5 to deflect, so that the turntable 5 can drive the insulating sleeve to deflect through two brackets 2 11 and multiple transmission frames 14. Brackets 1 3 of different diameters can be positioned, clamped and deflected to measure the thickness at different angles.

[0026] Reference Figure 3 , Figure 5 and Figure 6As shown, a second spring 17 is fixedly connected to the inner side of the guide rod 16. A locking block 18 is fixedly connected to both ends of the second spring 17. The outer side of the locking block 18 is slidably connected to the inner side of the guide rod 16. The outer side of the locking block 18 is engaged with the inner side of the transmission frame 14. Multiple third springs 26 are fixedly connected to the inner side of the guide rod 16.

By using the corresponding second spring 17 and locking block 18 to engage the inner side of the transmission frame 14, the guide rod 16 can avoid putting too much pressure on the insulating sleeve and avoid squeezing deformation of the insulating sleeve.

[0027] Reference Figure 1 and Figure 4 As shown, the detection and adjustment mechanism includes an electric push rod 20. The outer side of the electric push rod 20 is fixedly connected to the inner side of the bracket 3. A transmission frame 21 is fixedly connected to the top of the electric push rod 20. The outer side of the transmission frame 21 is slidably connected to the inner side of the bracket 3. A bolt 22 is inserted into the inner side of the transmission frame 21.

A capacitive sensor 25 is fixedly connected to the bottom of the bolt 22. By utilizing the deflection of the rotating plate 23, the electromagnetic sensor 24 and the capacitive sensor 25 can detect the top and side of the metal-based insulating sleeve and the all-plastic insulating sleeve.

[0028] The working principle of this utility model is as follows: Before measuring the thickness of the insulating sleeve on the metal substrate, the insulating sleeve is placed vertically above the turntable 5. Then, the corresponding worm gear 7 is rotated sequentially to engage the worm gear 8, and the worm gear 8 drives the screw 9 to rotate inside the guide frame 10. Then, the screw 9 drives the corresponding bracket 11 to slide on the top of the guide frame 10, so that the two brackets 11 drive the two corresponding transmission frames 14 to move in opposite directions. The clamping arms 19 at one end of the multiple transmission frames 14 clamp the two ends of the insulating sleeve. The two rotating rods 12 drive the threads 13 to move the two transmission frames 14 up and down in opposite directions. The two sets of transmission frames 14 can fix the two ends of the insulating sleeve. Then, the two clamping arms 19 at one end of the multiple guide rods 16 drive the... The push plate 27 pushes the two springs 26 on one side, so that the two clamping arms 19 at one end of the multiple guide rods 16 can relatively fit and fix the outer wall of the insulating sleeve. By sliding the multiple guide rods 16 inside the transmission frame 14, the springs 17 inside the guide rods 16 push the two locking blocks 18 to engage with the inner side of the transmission frame 14. When the clamping force of the multiple guide rods 16 on the outer wall of the insulating sleeve is too large, the guide rods 16 will push and compress the springs 15, thereby avoiding excessive pressure on the outer wall of the insulating sleeve by the guide rods 16. After the insulating sleeve is vertically fixed, the electromagnetic sensor 24 inside the rotating plate 23 generates an electromagnetic signal to the insulating sleeve, and then the capacitive sensor 25 monitors the electromagnetic signal inside the insulating sleeve, thereby detecting the wall thickness of the insulating sleeve.

[0029] When inspecting an all-plastic insulating sleeve, loosen bolt 22 to deflect the rotating plate 23 to one side of the transmission frame 21, then tighten bolt 22 to deflect and fix the rotating plate 23. Then, the electric push rod 20 drives the transmission frame 21 to move the bolt 22 up and down, causing the rotating plate 23 to move the electromagnetic sensor 24 and the capacitance sensor 25 closer to the outer wall of the insulating sleeve. Through the transmission of the turntable 5 by the servo motor 4, the insulating sleeve can be deflected, so that the electromagnetic sensor 24 and the capacitance sensor 25 can approach the non-conductive insulating sleeve to maintain accurate thickness measurement.
