[0025] The staff placed the track plate inside the rail slot 14 and between the two clamping plates 18, turned on the motor 8, and used it to drive gear 1 5 to rotate. Through the meshing of the teeth between gear 1 5 and gear 2 6, gear 1 5 drove gear 2 6 to rotate. Gear 2 6 then drove the bidirectional screw 3 to rotate inside the sleeve 4, causing the two sleeves 4 to move from the inside of the slide 2 toward the outer surface of the track plate. The sleeve 4 then drove the movable plate 16 to move. The movable plate 16 then drove the telescopic rod 2 17 and the clamping plate 18 to move synchronously. The track plate was then fixed by the clamping plate 18, thus completing the clamping and fixing of the track plate. The two rails were crimped and sealed at one end using bolts with a diameter no greater than 10mm. The other ends were installed with tightly connected terminals and connected to a bridge tester. Subsequently, the inductance LmH and resistance RmΩ between the two rails were measured at a frequency of 2000Hz. This was repeated three times and the average value was taken to ensure the data accuracy. Afterwards, the track plate was removed and the rails were placed on insulating wooden pads, restoring the original height and adjusting the track gauge to the standard value of 1435mm±3mm, while keeping the other end sealed. Finally, the inductance L0 and resistance R0 were measured again using the bridge tester under the same conditions.

Compared with the traditional device, this device The cooperation between the bidirectional screw rod 3 and the sleeve block 4 facilitates the driving of the clamping plate 18 to clamp and fix the track plate, ensuring that the track plate is stable and avoids errors caused by poor contact and position offset. At the same time, it effectively shields interference such as external vibration and temperature changes, ensuring the accuracy of measurement data. In addition, the device also greatly enhances the test efficiency, shortens the test preparation and cleaning time through fast and convenient installation and disassembly processes; its adjustable design meets diverse test needs, improves the adaptability and utilization of the equipment, and provides a solid guarantee for efficient and accurate insulation performance testing.
