摘　　要：目前吊管机采用液压助力刹车系统,一旦液压系统出现泄漏则无法保证制动带始终抱紧外轮毂,若车辆停留在斜坡上,则会由于自重出现溜坡现象,从而影响工程机械作业质量,甚至引发事故。为此,设计了一套机械式辅助制动系统:当发动机熄火时,该系统利用弹簧力实现车辆彻底制动;当发动机启动或电磁阀得电时,该系统不工作且不影响原有底盘转向制动系统,达到两种制动系统的兼容。该系统安装、使用、维修方便,解决了吊管机、推土机等履带式工程车辆的溜坡问题,对工程机械安全作业、高效精准施工具有重要意义。For present use of hydraulic boost brake system for the side-boom pipeline lifter once a leakage comes out you would not be able to keep the brake band to tightly embrace the outer hub.Further more,if the car is parked on a slope a slippage would happen as a result of the gravity,thus effecting operational quality of the working machine and even leading to an accident.Therefore,we designed a set of aux brake system that when the engine turned off,the system can apply the brake completely for the vehicle by means of a spring in the system,thus realizing compatibility of the 2 brake systems.Such a system is easy to install,operate,and maintain to have solved the problem of slippage on slope for side-boom tractors,bulldozers,and other track type earthmoving vehicles,and therefore,this system has important significance in work safety,high efficiency and precise operation for the earthmoving equipment.
