Abstract

The invention relates to the technical field of automatic measurement and warning, in particular to a collision prevention device and method for a ballast screening machine. The device comprises an ultrasonic transmitting master, a central information processor, ultrasonic obstacle-avoidance and ranging receivers, and an obstacle avoidance information processor, wherein the ultrasonic transmitting master which is an ultrasonic transmitter is mounted a lower rotation part of a transfer boom, the central information processor is mounted in the ultrasonic transmitting master and used for calculating information of parts, the ultrasonic obstacle-avoidance and ranging receivers which are obstacle positioning devices are mounted on a vertical obstacle, and the obstacle avoidance information processor transmits data from the ultrasonic obstacle-avoidance and ranging receivers to the central information processor. The collision prevention device and method for the ballast screening machine has the advantages that ultrasonic transmitting and ultrasonic receiving are separated by a transmitting function and the high frequency feature of ultrasonic, an ultrasonic through-beam structure is established, and the problem of inaccurate measurement caused by continuous falling of gravels is solved; two ultrasonic receivers are provided, one for measuring and the other for calibration, so that measurement precision is improved.

Description

technical field [0001] The invention relates to the technical field of automatic measurement and alarm, in particular to an anti-collision device and method for a ballast cleaning machine. Background technique [0002] The ballast cleaning machine is a kind of equipment for cleaning the ballast on the section of the railway track bed or on both sides of the slope. During the cleaning process, the cleaned ballast can be backfilled and the cleaned dirt The soil is dumped to both sides of the line or to the dirt truck through the conveyor belt on the rotary conveyor mechanism. At the same time, in order to increase the range of soil projection, the rotary conveyor mechanism can rotate at a certain angle, so that the rotary conveyor mechanism can be dumped within the radius of gyration. . [0003] The ballast cleaning machine plays an important role in the railway construction and maintenance process. With the widespread popularization of railway electrification, the ballast cl...
