Embodiment Construction
[0019] The features of the present invention and other relevant features are described in further detail below in conjunction with the accompanying drawings through the embodiments, so as to facilitate the understanding of those skilled in the art:
[0020] Such as Figure 1-5 , mark 1-11 among the figure is respectively: car body 1, reference line 2, tether 3, alarm circuit 4, alarm 5, switch 6, return spring 7, power supply 8, fixed point 9, rail 10, wheel 11.
[0021] Example: such as figure 1 , 2 , 3, this embodiment specifically relates to a train derailment alarm system and its application method, the alarm system is specifically composed of a reference line 2, a tether 3 and an alarm circuit 4. The reference line 2 is a long rope, which is horizontally arranged in the middle of each train car body 1, and a fixed point 9 is set at the midpoint of each car body 1 to fix the reference line. The alarm circuit 4 is arranged at the bottom of each car body 1, close to the w...

The invention in particular relates to a train derailment alarming system and an application method thereof. The alarming system comprises a reference line, an alarming circuit and a tether, wherein the reference line is transversely fixed in the middle of an adjacent vehicle body; the alarming circuit is arranged at the bottom of the vehicle body and comprises a power supply, an alarm and a switch which are connected with each other in series; the tether is arranged between the alarming circuit and the reference line; one end of the tether is connected with the reference line; the other end of the tether is connected with the switch; and when a train is derailed, the tether is broken, and the alarming circuit is triggered to alarm. The train derailment alarming system provided by the invention has the advantages as follows: simple structure, low cost and convenient implementation are achieved; and workers on a vehicle can be effectively prompted to find train derailment and make corresponding protective measures, so that the safety of the train during running is effectively guaranteed.
Description
technical field [0001] The invention belongs to the technical field of train fault monitoring, and in particular relates to a train derailment alarm system and an application method thereof. Background technique [0002] Train derailment is a sporadic accident that is difficult to prevent in railway accidents. Because there is no monitoring and alarm device installed on the train after the wheel derailment at present, the driver cannot know and take measures immediately after the wheel derailment. [0003] The reasons leading to derailment are more complicated. There are more obvious single factors, such as obvious defects of the line or the problems of rolling stock itself, etc., and there are also less obvious comprehensive factors, and the reasons are difficult to determine. In terms of the form of derailment, there are wheel climbing derailment, wheel jumping derailment, wheel suspension derailment, technical derailment and wheel-rail relationship derailment, etc. The ...
