[0019] Reference Figure 1-3, a leakage detection device for the brake pipeline of an EMU, comprising a base 1 and a detection device body 9, the detection device body 9 being an ultrasonic leakage detector, the upper end of the base 1 being fixedly connected to a vertically arranged pillar 2 for supporting a support block 4, the upper end of the pillar 2 being fixedly connected to a support block 4 for supporting a support rod 7, a triangular fixed block 3 being fixedly connected between the outer side wall of the pillar 2 and the lower end of the support block 4 for supporting the support block 4, a transversely arranged support rod 7 being fixedly connected to the outer side wall of the support block 4 for supporting a slider 6, a fixed ring 5 being fixedly sleeved on one end of the support rod 7 close to the support block 4 for improving the firmness between the support rod 7 and the support block 4, one side of the fixed ring 5 being fixedly connected to the outer side wall of the support block 4, and an anti-slip block 8 being fixedly connected to one end of the support rod 7 away from the support block 4 for preventing the slider 6 from slipping off the support rod 7;

[0020] In this embodiment, a slider 6 is provided on the sliding sleeve of the support rod 7 for facilitating user adjustment of the left and right position of the detection device body 9. A storage slot is provided at the lower end of the slider 6. A control switch 10 is fixedly connected to the outer wall of the slider 6 for controlling the start and stop of the servo motor 11. The output end of the control switch 10 is electrically connected to the input end of the servo motor 11. A servo motor 11 is fixedly connected to the outer wall of the slider 6 for driving the winding reel 12 to rotate. The end of the output shaft of the servo motor 11 passes through the slider 6 and is rotatably connected to the inner wall of the storage slot. The output shaft of the servo motor 11 is rotatably connected to the slider 6.

[0021] In this embodiment, a winding wheel 12 is fixedly provided on the output shaft of the servo motor 11 for winding and unwinding the lifting rope 13. A lifting rope 13 is wound around the winding wheel 12 for lifting the detection equipment body 9. The lifting rope 13 is made of nylon material to improve strength. One end of the lifting rope 13 is fixedly connected to the winding wheel 12, and the lower end of the lifting rope 13 passes through the storage slot.

The detection device body 9 is supported by the lifting rope 13 to avoid the hand from bearing the weight of the detection device body 9, thereby reducing labor intensity. At the same time, the slider 6 is manually pushed to slide left and right on the support rod 7. The left and right position of the detection device body 9 is adjusted by sliding the slider 6 left and right, so as to perform detection operations on pipelines at different positions under the vehicle. At the same time, the servo motor 11 is controlled to start and stop by the control switch 10, and the winding wheel 12 is driven by the servo motor 11 to be installed or reversed, so that the winding wheel 12 can reel and unwind the hanging rope 13, thereby realizing the height adjustment of the detection device body 9 to meet the usage requirements in different scenarios.
