Safety alarm system for over-limit construction operation of ballast cleaning and screening vehicle

Abstract

The invention discloses an alarming system for safety of ultralimit construction operation of a railway ballast cleaning vehicle. The alarming system comprises an angle sensor, a distance measurement sensor and a man-machine interaction module. The angle sensor is used for measuring the real-time angle of a dirty soil rotation conveying device of the railway ballast cleaning vehicle. The distance measurement sensor is used for measuring the traveled distance of the railway ballast cleaning vehicle and forming mileage information. A data processing module is used for processing data information collected by the angle sensor and the distance measurement sensor and outputting the processed data information to the man-machine interaction module to trigger an alarm and achieve barrier-avoiding motions. The man-machine interaction module is used for displaying detection data processed by the data processing module and displaying a construction operation safety alarm. According to the method, the railway ballast cleaning vehicle can sound an alarm within a set distance, in an emergency, the dirty soil rotation conveying device can be triggered to stop swinging, or the railway ballast cleaning vehicle can stop operation and walking, construction safety is guaranteed, influences caused by vibration and dust are reduced, and reliability of the system is greatly improved.

Description

technical field [0001] The invention relates to a railway safety operation vehicle, in particular to a safety alarm system for ballast cleaning and screening vehicle overrun construction operation applied in the field of railway engineering. Background technique [0002] The ballast cleaning and screening vehicle (hereinafter referred to as the cleaning and screening vehicle) is an operating machine used to clean the ballast in the ballast bed. It digs out the dirty ballast from the bottom of the pillow, screens it, and then backfills the clean ballast into the The track bed, and the sieved dirt is removed out of the line through the rotary dirt conveying device. In the prior art, the RM80 type full-section road was disclosed in the master's degree thesis "Research on the Insufficient Excavation Capacity of the RM80 Type Full-Section Ballast Screening Machine" published by Ma Liangmin of Southwest Jiaotong University on March 1, 2003.

Problems solved by technology

However, the hardware of the device is complicated, and components such as ultrasonic sensors, stepping motors, driver modules, and proximity switches are installed on the dirt conveyor belt. However, the construction environment of the cleaning vehicle is harsh, and the dirt conveyor belt vibrates greatly and is covered with dust. serious situation

On the one hand, it is easy to cause the base of the ultrasonic sensor to be unstable, and there is a large error in the real-time calculation of the distance; on the other hand, the dust and slag can easily cause the proximity switch to work unreliably, and the system cannot work reliably and stably
