Description

Technical Field

[0001] The utility model relates to a locomotive coupler force real-time monitoring system, belonging to the technical field of real-time monitoring and data analysis of track locomotive coupler force. Background Art

[0002] The coupler system is a key component that connects locomotives and vehicles and transmits traction and braking force. Therefore, studying the coupler force during locomotive and vehicle operation, how to reduce the harmful effects of sudden changes in coupler force, how to obtain real-time data on coupler force, and how to accurately measure and analyze the coupler force during the impact of the central locomotive are of great practical significance to the safety of heavy-load trains.

[0003] At present, the main method for measuring the coupler force is to arrange strain gauges on the coupler, calibrate the coupler, measure the surface strain of the coupler, and use the relationship between the surface strain of the coupler and the coupler force to obtain the coupler force to be measured. This method requires the arrangement of strain gauges and wiring on the coupler. These strain gauges and wiring are easily damaged and fail during the normal operation of the locomotive, making it impossible to perform their functions. At the same time, since the coupler needs to be frequently inspected and maintained, after inspection or replacement of the coupler, the strain gauges and wiring need to be reinstalled, and the coupler needs to be recalibrated. The whole process is extremely cumbersome and difficult to complete at the application site.

[0004] Some coupler force monitoring technologies do not require strain gauges to be arranged on the coupler, but it is necessary to obtain characteristic data of the locomotive coupler, match the corresponding strain unit setting plan according to the obtained characteristic data of the coupler, and thus monitor the coupler force. This method lacks universality. Utility Model Content

[0005] The utility model aims to solve the above technical problems and provide a locomotive coupler force real-time monitoring system which can monitor the coupler force in real time without arranging strain gauges on the coupler and obtaining characteristic data of the coupler.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A locomotive coupler force real-time monitoring system includes a coupler system, the coupler system includes a coupler box, a coupler device is arranged in the coupler box, a front follower plate seat is arranged at the front end of the coupler box, a front follower plate is arranged in front of the coupler device, a rear follower plate seat is arranged at the rear of the coupler box, and a rear follower plate is arranged behind the coupler device. It also includes a sensor module arranged on the coupler box, the sensor module includes a first pressure sensor arranged between the front follower plate and the front follower plate seat and a second pressure sensor arranged between the rear follower plate and the rear follower plate seat; it also includes a signal amplifier and collector arranged in the car body; the signal output ends of the first pressure sensor and the second pressure sensor are both electrically connected to the signal input end of the signal amplifier and collector; the signal output end of the signal amplifier and collector is electrically connected to the signal input end of the vehicle-mounted monitoring system arranged in the car body.

[0008] Therefore, after the coupler device is installed normally, the coupler device will press the first pressure sensor and the second pressure sensor. When the vehicle is running, the front follower plate and the rear follower plate of the coupler device will continuously squeeze the first pressure sensor and the second pressure sensor. The first pressure sensor is used to measure the original voltage signal of the coupler force acting on the vehicle body structure under traction, and the second pressure sensor is used to measure the original voltage signal of the coupler force acting on the vehicle body structure under braking. Then, the original voltage signal of the coupler force measured by the first pressure sensor and the second pressure sensor is transmitted to the signal amplification and acquisition module. Finally, the signal amplification and acquisition module transmits the collected coupler force signal to the on-board monitoring system to complete the real-time monitoring of the coupler force.

[0009] According to the embodiments of the present invention, the present invention can be further optimized. The following is the technical solution formed after optimization:

[0010] In order to facilitate the installation of the sensor and prevent the sensor mounting bolts from being cut off when the sensor is subjected to vertical force, thereby causing the sensor to fall onto the track, specifically, the first pressure sensor is bolted to the front slave plate seat, and a boss is provided on the side of the front slave plate seat toward the front slave plate, and the first pressure sensor is provided on the inner side of the boss.

[0011] Specifically, a notch is provided below the boss for routing the first sensor.

[0012] Specifically, the second sensor is fixedly arranged at the rear of the coupler box by means of bolts.

[0013] Specifically, the signal amplification and acquisition module includes a signal amplifier and a signal collector. The signal output ends of the first pressure sensor and the second pressure sensor are electrically connected to the signal input ends of the signal amplifier and the signal collector. The signal output ends of the signal amplifier and the signal collector are electrically connected to the signal input end of the vehicle-mounted monitoring system.

[0014] The signal amplifier can amplify the original voltage signal of the coupler force measured by the first and second pressure sensors and transmit it to the signal collector. The signal collector collects and saves the signal. The signal amplifier and signal collector then transmit the collected coupler force signal to the on-board monitoring system.

[0015] Specifically, at least two of the first pressure sensor and the second pressure sensor are provided.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The locomotive coupler force real-time monitoring system of the present invention measures the coupler force by fixing the sensor on the vehicle body structure. It is not necessary to arrange strain gauges on the coupler. The placement of the sensor is more stable, and the size of the coupler force can be monitored in real time, avoiding the defects of short monitoring time, small and incomplete data, short service life of the monitoring device, and affecting the coupler maintenance in the past coupler force monitoring. At the same time, it is not necessary to obtain the characteristic data of the coupler and monitor the coupler force based on this, making it more versatile. BRIEF DESCRIPTION OF THE DRAWINGS
