摘要
介绍了矿用带式输送机清扫器的类型,阐述了清扫器的清扫机理,分析了清扫器工作环境和工作特性,针对目前矿用带式输送机清扫器在清扫过程中出现的工作位置不稳定和清扫器磨损状态不确定等问题,根据清扫器的设计准则,设计了一种清扫效果稳定的头部智能清扫器。介绍了清扫器设计方案,依据设计方案作出总体设计,并主要列举了该清扫器的机械系统和液压系统。电气控制系统对液压系统输入信号,液压系统驱动机械系统进行清扫。该液压系统使用双回路设计,采用带有蓄能器和压力传感器的主回路和辅助供液回路,通过实时监测液压缸无杆腔压力向泵站发出信号来实现压紧力的调节,压力传感器实时监测液压缸无杆腔压力,实现具有动态调节能力的清扫系统;蓄能器能保证在煤渣黏结顽固等极端条件下,清扫器不损伤输送带。通过AMESIM软件对液压系统进行仿真验证,实现了在较大冲击工况下,避免清扫器损伤输送带的情况,同时具有高速的动态响应能力,验证了该清扫器可以达到稳定清扫的目的。
Introduces the types of mine belt conveyor sweeper,describes the cleaning mechanism of the sweeper,analyzes the working characteristics of the sweeper under different working environments.Aiming at the problems of unstable working position and uncertain wear state of the mine belt conveyor sweeper in the cleaning process at present,according to the design criteria of the sweeper,a kind of head intelligent sweeper with stable cleaning effect is designed.Expounds the design scheme of the cleaner,according to the design scheme to make the overall design and hydraulic system design,and mainly describes the mechanical system and hydraulic system of the cleaner.The electrical control system inputs signals to the hydraulic system,and the hydraulic system drives the mechanical system to clean.The hydraulic system uses double circuit design,using the accumulator and pressure sensor with the main circuit and auxiliary liquid supply circuit,through real-time monitoring of hydraulic cylinder rodless chamber pressure to pump station signals to achieve compression force regulation,pressure sensor real-time monitoring of hydraulic cylinder rodless chamber pressure,to achieve a dynamic regulation of the cleaning system;The accumulator can ensure that the cleaner does not damage the conveyor belt under extreme conditions such as stubborn cinders.The hydraulic system is simulated and verified by AMESIM software,which realizes that the conveyor belt is not damaged by the cleaner under large impact conditions,and has high-speed dynamic response capability,which verifies that the cleaner can achieve the purpose of stable cleaning.
