Embodiment 1
[0034] Such as Figure 1 to Figure 3 As shown, the present invention provides a kind of trouble-shooting method and trouble-shooting device for rail vehicle, and trouble-shooting device comprises air supply air source 1 and injection device 2, and air supply wind source 1 and spray device 2 are connected by air pipe 3 . There are two spraying devices 2, which are respectively connected to the same air supply source 1 through the air pipe 3, or each spraying device 2 is equipped with a supply air source 1.
[0035] In this embodiment, the air supply air source 1 is an air supply air cylinder provided separately for troubleshooting, and the air supply air cylinder is fixedly installed on the vehicle body chassis (not shown in the figure) or on the frame 4 of the bogie. The specifications of the air supply cylinder are determined according to the required air pressure and air volume, generally guaranteed to be 5kg / m 3 The air pressure can meet the needs of troubleshooting. It c...
Embodiment 2
[0049] The difference from Embodiment 1 is that, as Figure 4 As shown, when the axle box body 5 is not suitable for installing the injection device 2, the injection device 2 can be fixedly installed on the frame 4 of the bogie, and a frame mounting seat 13 protrudes downward on the frame 4 in front of the wheel 8, and the injection Spray pipe 6 in the device 2 is installed on the frame mounting seat 13, makes the nozzle mouth of nozzle pipe 6 be positioned at the front of wheel 8, and baffle plate 10 is set in front of the nozzle pipe mouth of nozzle pipe 6.
[0050] In the prior art, due to the action of the spring between the frame 4 and the axle box 5, the height of the obstacle removal device installed on the frame 4 from the rail surface will change continuously. When the obstacle is less than 30mm, the obstacle removal The device will not work at all, but the high-pressure air will not be affected by the up and down movement of the frame 4, and the high-temperature and ...
Embodiment 3
[0052] The difference from the above-mentioned embodiment is that, if Figure 5 As shown, the injection device 2 can also be fixed on the underframe of the car body, installed on the front end of the underframe of the car body, and protrude a mounting seat (not shown in the figure) downwards on the underframe in front of the wheel 8, spraying Spray pipe 6 among the device 2 is installed on the mounting seat, makes the nozzle mouth of nozzle pipe 6 be positioned at the front of wheel 8, and baffle plate 10 is set in front of the nozzle pipe mouth of nozzle pipe 6.
