[0027] As Figures 1-4As shown, the present embodiment proposes a city rail vehicle derailment warning device, which comprises a warning frame 1, a mounting hook 2 is arranged in the center of the warning frame 1, a sealing rubber strip 3 is arranged at the inner end of the mounting hook 2, two telescopic rods 4 are arranged at the two ends of the warning frame 1 respectively, a linkage ring 5 is arranged at the outer end of the telescopic rod 4, a positioning cylinder 8 is arranged at the inner end of the linkage ring 5, a positioning rod 7 is arranged at the inner end of the positioning cylinder 8, an infrared monitoring meter 6 is arranged at the outer end of the positioning rod 7, a linkage spring 9 is arranged at the upper end of the infrared monitoring meter 6, a linkage cylinder 10 is arranged at the upper end of the linkage spring 9, a positioning seat 11 is arranged at the upper end of the linkage cylinder 10, positioning screws 12 are arranged through the front and rear ends of the positioning seat 11, a balance cylinder 13 is arranged at the inner end of the warning frame 1, a balance sensing plate 14 is arranged in the center of the balance cylinder 13, and balance balls 15 are arranged at the two ends of the balance sensing plate 14.
[0028] The active detection working principle of the infrared monitoring meter 6: The infrared monitoring meter 6 is based on the optical principle, emits infrared rays and receives the reflected information, and monitors the distance between the vehicle and the track in real time. It can detect any object that causes refraction or absorption of light, such as obstacles or track deviation, so as to evaluate whether the position of the vehicle remains within the preset safety range.
[0029] Function: When the infrared monitoring meter 6 detects that the vehicle deviates from the track, that is, the intensity of the received infrared rays changes, which may be caused by the vehicle deviating from the predetermined path or other reasons.
[0030] The warning frame 1 serves as the main structure, the mounting hook 2 is arranged in the center, the sealing rubber strip 3 is arranged inside to ensure stability, the telescopic rods 4 are arranged at the two ends, the linkage ring 5, the positioning cylinder 8, and the positioning rod 7 are arranged at the end, and finally the infrared monitoring meter 6 is carried.
[0031] The linkage spring 9, the linkage cylinder 10, and the positioning seat 11 are arranged at the upper part, and the positioning screws 12 are used to realize firm combination with the vehicle.
[0032] The balance cylinder 13, the balance sensing plate 14, and the two balance balls 15 are arranged inside.
[0033] The sealing rubber strip 3 is tightly attached to the inner end of the mounting hook 2, the two ends of the warning frame 1 are fixedly connected with the fixed ends of the telescopic rods 4 respectively, the movable end and the fixed end of the telescopic rod 4 are provided with meshing connection toothed blocks, and the movable end of the telescopic rod 4 is fixedly connected with the linkage ring 5.
[0034] The toothed blocks between the movable end of the telescopic rod 4 and the linkage ring 5 ensure the adjustability and stability of the structure, and realize the adaptation to different vehicle types.
[0035] The infrared monitoring meter 6, the linkage assembly (the linkage spring 9, the linkage cylinder 10), and the positioning seat 11 construct a dynamic monitoring system, which monitors the position change of the rail vehicle in real time.
[0036] The front and back ends of the linkage ring 5 are fixedly connected with the positioning cylinder 8, the inner end of the positioning cylinder 8 is movably connected with the positioning rod 7, the positioning rod 7 is fixedly connected with the infrared monitor 6, the upper end of the infrared monitor 6 is fixedly connected with the lower end of the linkage spring 9, and the upper end of the linkage spring 9 is fixedly connected with the linkage cylinder 10.
[0037] The linkage cylinder 10 is wrapped on the outer surface of the upper end of the infrared monitor 6, the linkage cylinder 10 is fixedly connected with the positioning seat 11, the positioning seat 11 is movably connected with the positioning screw 12, and the positioning seat 11 and the mounting hook 2 are connected with the bottom of the urban rail vehicle.
[0038] The balance cylinder 13 is embedded in the central inner end of the early warning frame 1, the center of the balance cylinder 13 is divided by the balance induction plate 14, the balance induction plate 14 is fixed on the inner end of the balance cylinder 13, and the balance balls 15 are along the inner surfaces of the two ends of the balance cylinder 13.
[0039] The balance induction plate 14 is provided with a gravity sensor, and the balance cylinder 13 is in the shape of an upward opening arc.
[0040] The balance induction plate 14 is provided with two balance balls 15, which can move with the vehicle. When the vehicle is driving forward, the two balance balls 15 should be kept on the same horizontal line, reflecting the balance state of the vehicle.
[0041] The function of the gravity sensor: The gravity sensor is arranged in the balance induction plate 14, which is used to sense the acceleration in the vertical direction, especially sensitive to the change of the earth's gravity, so as to monitor the overall attitude and gravity distribution of the vehicle.
[0042] The balance induction plate 14 cooperates with the gravity sensor to judge the state of the vehicle through the action of the balance ball 15, and provides the steering or tilting information.
[0043] The design of the balance cylinder 13 is beneficial to the free rolling of the balance ball 15, and enhances the accuracy of signal acquisition.
[0044] When the urban rail vehicle is running:
[0045] The infrared monitor 6 continuously scans the distance between the vehicle and the track, and once the deviation is found:
[0046] If the balance induction plate 14 only feels the change of gravity on one side, it means that the vehicle is in normal turning.
[0047] If both sides simultaneously perceive gravity anomaly, it indicates that the vehicle may be side deviation, which needs to be further checked and adjusted.
[0048] Monitoring process:
[0049] a. If the infrared monitor 6 finds that the vehicle position deviates, but the balance induction plate 14 shows that the vehicle is still in the normal balance state (i.e. the balance ball 15 does not have obvious displacement), it is preliminarily judged that the vehicle may be in the turning operation within a reasonable range, rather than the derailment danger.
[0050] b. Conversely, if the infrared monitor 6 prompts the deviation while the gravity sensor also detects the abnormality (for example, the balance ball 15 on one side of the balance induction plate 14 is deviated to one side due to the gravity, indicating that the vehicle is tilted), it is highly warned that the vehicle may have a serious risk of deviating from the track, triggering the emergency brake or warning the driver to take action.
[0051] In use, in order to monitor the deviation degree between the urban rail vehicle and the track in real time, the early warning frame 1 is fixed at the bottom of the urban rail vehicle, and is fixed by installing the hook 2 and the sealing rubber strip 3, in order to facilitate the installation of different models of rail vehicles, the bottom end of the early warning frame 1 is moved by the telescopic rod 4, the movable end of the telescopic rod 4 is connected with the infrared monitor 6 through the linkage ring 5, and is connected with the positioning seat 11 located at the upper end of the linkage cylinder 10 through the linkage spring 9 and the linkage cylinder 10 at the upper end of the infrared monitor 6, and is fixed at the top of the track part at both ends of the urban rail vehicle through the positioning seat 11 and the positioning screw 12, and in the monitoring process of the infrared monitor 6, if the infrared monitor 6 monitors the deviation, the balance induction plate 14 and the gravity sensor are monitored by the balance ball 15 in the balance cylinder 13.
[0052] When the infrared monitor 6 generates the monitoring deviation and the balance induction plate 14 has the gravity induction on only one side, it indicates that the urban rail vehicle is deviated from the track due to the turning.
[0053] When the infrared monitor 6 generates the monitoring deviation and the balance induction plate 14 has the gravity induction on both sides, it indicates that the urban rail vehicle is deviated from the track, and needs to be adjusted and monitored.
[0054] The above embodiments are only used to illustrate the technical solutions described in the present application, and the present application is not limited to the above specific embodiments, therefore any modification or equivalent replacement of the present application is allowed, and all technical solutions and improvements without departing from the spirit and scope of the present application are covered in the scope of the claims of the present application.
