The invention belongs to the technical field of chassis deviation correction system control, and provides a mining hydraulic track chassis deviation correction system and a control method.The system comprises a track chassis, an ultrasonic sensor, a proportional valve and a controller, and the ultrasonic sensor, the proportional valve and the controller are installed on a track chassis platform; according to the control method, the driving deviation direction of the hydraulic crawler chassis is judged by collecting the distances from the ultrasonic sensors to the wall surfaces on the two sides of the roadway, the duty ratio of the proportional valve is controlled according to the deviation direction so as to control the hydraulic oil flow of the motor, the deviation condition of the crawler chassis is detected in real time, and the effect of correcting the crawler offset in real time is achieved; the linear driving offset displacement of the crawler chassis can be controlled within the range of 240mm; when the device is applied to the mining hydraulic crawler, the driving direction of the mining hydraulic crawler can be automatically adjusted not to deviate from the center line of a roadway, and collision accidents in a narrow roadway are avoided.

本发明属于底盘纠偏系统控制技术领域，提供了一种矿用液压式履带底盘纠偏系统及控制方法，所述系统包括履带底盘和安装在履带底盘平台上的超声波传感器、比例阀、控制器；所述控制方法通过超声波传感器采集距离巷道两侧墙面的距离判断液压履带底盘行驶的偏离方向，根据偏离方向控制比例阀的占空比进而控制马达液压油流量，实时检测履带底盘的偏移情况，实现了对履带偏移量进行实时纠正的效果，可将履带底盘直线行驶偏移位移控制在240mm范围内；将本发明应用于矿用液压履带车可自动调整其行驶方向不偏离巷道中心线，保障其在狭窄巷道中不发生碰撞事故。
