Embodiment 1

[0025] A remote diagnosis device for train running faults, comprising a housing 1, a horizontal plate 3, a sensor group 10 fixed on the horizontal plate 3, a signal processing and transmission device 13, a central processing system 11, a data input and output interface device 4 and a vehicle The image acquisition device 12, the upper end of the housing 1 is fixedly connected with two fixed blocks, and the opposite sides of the two fixed blocks are fixedly connected with a rectangular rod 8 horizontally, and a connecting mechanism is provided on the rod wall of the rectangular rod 8, and the housing 1 The upper end of the upper end is fixedly connected with a horizontal tube 19, and a buffer mechanism is arranged in the horizontal tube 19. The buffer mechanism is connected with the connecting mechanism on the two rectangular rods 8. The connecting mechanism includes a rectangular tube 9 slidingly sleeved on the rectangular rod 8, and the rectangular tube The upper end of 9 is fi...

Embodiment 2

[0027] Embodiment 2: the difference based on Embodiment 1 is;

[0028]The buffer mechanism includes two cross bars 18 that are movably socketed in the cross tube 19, and the opposite ends of the two cross bars 18 are fixedly connected with a piston 21, and the side wall of the piston 21 is fixedly connected with a sealing ring 22, and the cross bar 18 is away from the One end of the piston 21 extends to the outside of the cross tube 19 and is fixedly connected to one side of the rectangular tube 9. The air bag 20 with an oval structure is fixedly connected in the cross tube 19. The piston 21 is connected in contact.

[0029] The present invention is provided with a buffer mechanism. When in use, when the transmission rod 15 in the connecting mechanism swings, the mounting plate 16, the connection plate 14 and the two transmission rods 15 form a rhombus together, and when the tension spring 17 pulls the transmission rod 15 to swing , the rectangular tube 9 below the connecting...

Embodiment 3

[0030] Embodiment 3: the difference based on embodiment 1 is;

[0031] The fixing mechanism includes a fixing rod 23 slidingly sleeved in the cylindrical groove. One end of the fixing rod 23 extends into the fixing groove and has an inclined surface. The other end of the fixing rod 23 is fixedly connected with a first spring 27, and the first spring 27 is away from the One end of the fixed rod 23 is fixedly connected with one side of the cylindrical groove, and the lower side of the horizontal plate 3 is provided with a strip-shaped through hole communicating with the cylindrical groove, and the strip-shaped through-hole is slidably connected with a brake lever 28. One end passes through the strip-shaped through hole and is fixedly connected with the rod wall of the fixed rod 23. The inner walls of the opposite sides of the rectangular frame 5 are fixedly connected with sliding sleeves 25, and the two sliding sleeves 25 are slidingly sleeved with the top of the T-shaped structu...

Abstract

The invention relates to the technical field of train fault diagnosis, and discloses a remote diagnosis device for train operation faults, which includes a housing, a horizontal plate and a sensor group fixed on the horizontal plate, a signal processing and transmission device, a central processing system, a data input and The output interface device and the vehicle image acquisition device, the upper end of the housing is fixedly connected with two fixed blocks, and the opposite sides of the two fixed blocks are horizontally fixedly connected with a rectangular rod, and the rod wall of the rectangular rod is provided with a connecting mechanism. The upper end of the casing is fixedly connected with a horizontal tube, and a buffer mechanism is arranged in the horizontal tube, and the buffer mechanism is connected with the connection mechanism on the two rectangular rods, and the lower end of the housing is provided with an opening matching the horizontal plate. The remote diagnosis device for train operation faults can facilitate the maintenance of the audio-visual detection system and the acquisition of data in the audio-visual detection system, and can effectively reduce the influence of external factors on the audio-visual detection system during use.

Description

technical field [0001] The invention relates to the technical field of train fault diagnosis, in particular to a remote diagnosis device for train operation faults. Background technique [0002] The EMU dynamic fault detection system can detect the faults in the EMU operation, which is conducive to improving the safety factor of the EMU operation. The EMU intelligent audio-visual fault detection system uses the high-speed line array camera and microphone array installed on the side of the track to collect the data of the EMU respectively. Images of visible parts such as the bottom, skirts on both sides, connecting devices, bogies, etc., and sounds of audible parts such as wheel set bearings and fans, automatically identify faults, and realize hierarchical fault alarms. However, the side skirts and chassis of the EMU The structure is complex, the number of installed parts is large, and the space is small. It is not convenient to maintain the fault diagnosis device and obtain ...
