Description

Technical Field

[0001] This utility model relates to the field of transportation, and in particular to an obstacle detection device. Background Technology

[0002] During the operation of rail vehicles, obstacles such as gravel, metal fragments, and large foreign objects may appear within the track clearance. If these obstacles are not detected in time, they may collide with the train, causing damage to the train body and undercarriage equipment, or even serious safety accidents such as derailment and overturning. Especially for high-speed rail vehicles, the instantaneous impact force of obstacle collision is extremely large, which not only increases equipment maintenance costs and interrupts operations, but may also threaten the lives of passengers. Therefore, effective detection of obstacles in the rail vehicle's travel path and triggering protection mechanisms have become a key requirement to ensure the safe operation of rail transit.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3 This utility model provides an embodiment of an obstacle detection device, including a fixed beam 1. The fixed beam 1 mainly supports and connects the spring component 2, locking cable 5, sensor 7, etc. A collision beam 3 is provided on the right side wall of the fixed beam 1 via the locking cable 5. The collision beam 3 is made of steel and can contact foreign objects on the train track. A cover plate 4 is detachably installed on the outer wall of the collision beam 3. A sensing mechanism is provided on the right side wall of the fixed beam 1. A spring component 2 is provided between the fixed beam 1 and the collision beam 3. A connector 8 is provided on the left side wall of the fixed beam 1. The connector 8 is connected to the sensor 7. The signal from sensor 7 is transmitted to the vehicle system via connector 8 and cable. The left side wall of the fixed beam 1 is fixedly connected to clamp 9 by fastening bolt 11. The clamp 9 can fix the cable and ensure that the cable is stable in position during the operation of the device, so as to avoid the cable from loosening, displacement or damage due to vibration and other factors during train operation, thereby ensuring the stability and reliability of the signal transmitted by the cable. The upper end of the fixed beam 1 is detachably installed with connecting bolt 10. The fixed beam 1 can be fixedly installed on the front and rear supports of the train by connecting bolt 10 to ensure the stability of the entire device.

[0026] Reference Figures 5-6 The sensing mechanism includes a protective shell 6, which mainly protects the sensor 7. The protective shell 6 is fixedly connected to the right side wall of the fixed beam 1. The sensor 7 is installed on the inner wall of the protective shell 6. The sensor 7 is an existing displacement sensor. It can determine whether the displacement has reached the trigger threshold by monitoring the change in distance between the collision part and the probe of the sensor 7. It is existing technology and will not be described in detail here.

[0027] Reference Figures 1-3 The right side wall of the fixed beam 1 is fixedly connected to one end of the spring member 2, which will compress the spring member 2. When resetting, the spring member 2 is used to carry the collision beam 3 to reset. The other end of the spring member 2 is fixedly connected to the left side wall of the collision beam 3.

[0028] The right side wall of the fixed beam 1 is fixedly connected to one end of the locking cable 5. The locking cable 5 is made of existing flexible steel material. When the collision beam 3 is displaced, the locking cable 5 will deform. When the collision beam 3 is reset, it returns to its initial state. It mainly serves to connect the collision beam 3 and prevent the collision beam 3 from separating from the fixed beam 1. The other end of the locking cable 5 is fixedly connected to the left side wall of the collision beam 3.

[0029] Reference Figures 2-4 The locking cable 5 is provided in two sets, and the two sets of locking cables 5 are symmetrically arranged with respect to the center of the fixed beam 1.

[0030] Two sets of spring components 2 are provided, and the two sets of spring components 2 are symmetrically arranged with respect to the center of the fixed beam 1.

[0031] Working principle: Before use, the entire fixed beam 1 is installed on the front and rear supports of the train using connecting bolts 10. This ensures the stability of the entire device during train operation and allows it to function properly. Simultaneously, one end of the existing cable is connected to the connector 8, and the other end is connected to the train's engine. The cable is then secured to the fixed beam 1 using clamps 9 and fastening bolts 11. When the device is in use, foreign objects on the train track will first contact the collision beam 3. The reaction force between the foreign object and the collision beam 3 causes the collision beam 3 to move to the left and compress the spring 2. The spring 2 then partially... The collision energy is converted into elastic potential energy. As the collision beam 3 continues to move to the left, the distance between it and the sensor 7 probe gradually decreases. The sensor 7 captures the distance change in real time. When the displacement of the collision beam 3 reaches the preset trigger threshold of the sensor 7, the sensor 7 is triggered and generates an electrical signal, indicating that an obstacle has been detected. The trigger signal generated by the sensor 7 is transmitted to the connector 8, and then the connector 8 transmits the signal to the train's onboard system, such as the TCMS system. After receiving the signal, the onboard system performs logical judgment and activates the corresponding protection mechanism to make the train decelerate or stop in time, reducing the damage of the obstacle to the train equipment.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
