Description

一种煤矿带式输送系统落煤冲击能量缓冲监测装置及方法 技术领域
本发明涉及一种皮带运输系统落料处冲击能量缓冲监测装置及方法，尤其适用于对长运距、大载荷、高速度的煤矿带式输送系统落料处的冲进能量进行缓冲和监测。
背景技术
带式输送机由于具有输送量大、结构简单、运距长等特点被广泛用于煤炭井下和地面主要运输巷道中，是煤矿生产的“大动脉”。输送带，作为带式输送系统中最重要的传动部件，同时也是带式输送系统中最昂贵和最易损坏的部件，由于受到机头处落料的冲击而经常发生损坏，给煤矿造成了巨大的损失。为了减轻落煤处冲击对输送带的破坏，目前常用的方法是在机头落煤处加装缓冲托辊或者缓冲床。其中，缓冲托辊由于支撑点较小，容易被落煤冲击力破坏。而缓冲床为了减小皮带与缓冲介质之间的摩擦力，需要采用高弹性特种橡胶层，对材料要求较高。都不能很好的满足现有的要求。
同时，落煤处也是皮带运输机堆煤事故直接影响区域。根据煤炭安全规程，带式输送机在运行过程中必须进行堆煤保护措施。而现有的堆煤保护装置多集中在在煤仓上口或两带式输送机搭接处加装堆料触发装置，这种装置存在受湿度影响较大且对块煤不灵敏的问题。
因此，必须研制一种能够抵抗落煤冲击且与皮带摩擦较小的缓冲承载装置，才能够缓解落煤冲击力对皮带的破坏，同时需要对落煤冲击力进行有效监测，才能够了解落煤状况，进行堆煤保护。
发明内容
发明目的：本发明针对大型带式输送机落料处落煤冲击力会对皮带产生破坏的问题，克服原有技术不足，设计了一种能够缓解落煤冲击力对皮带破坏且对落煤状况进行监测的装置及方法。

本发明中，优选的，所述缓冲皮带滚筒组包括水平缓冲皮带滚筒组和对称设置在水平缓冲皮带滚筒组两侧的倾斜缓冲皮带滚筒组，倾斜缓冲皮带滚筒组倾斜向上；所述水 平缓冲皮带滚筒组和倾斜缓冲皮带滚筒组均包括若干数量相等且等间距布置的滚筒组单元，每个滚筒组单元包括至少两个滚筒，滚筒套设在滚轴上，在滚筒外套设橡胶环。
本发明中，优选的，所述倾斜缓冲皮带滚筒组的滚轴上端设有橡胶条一，橡胶条一通过螺栓与缓冲托架固定；水平缓冲皮带滚筒组的滚轴两端设有橡胶条二，橡胶条二通过沉头螺钉与缓冲托架固定。
本发明中，优选的，所述缓冲托架包括加强筋板、水平加强筋板和竖直加强筋板，水平缓冲皮带滚筒组下方设有平行于水平缓冲皮带滚筒组的加强筋板和竖直加强筋板，倾斜缓冲皮带滚筒组下方设有平行于倾斜缓冲皮带滚筒组的加强筋板和水平加强筋板。
本发明中，优选的，所述冲击能量缓冲阻尼包括上层橡胶隔离层，永磁体，线圈、防爆外壳和螺纹旋转体，上层橡胶隔离层和永磁体通过螺纹旋转体与缓冲托架固定，线圈套设在永磁体上，线圈与永磁体接触部分包裹防爆外壳。
本发明中，优选的，所述信号转化发送装置包括整流装置，整流装置分别连接冲击能量收集阻尼和逆变器，逆变器连接电流测量装置，电流测量装置连接无线路由器，无线路由器连接平板天线。
一种煤矿带式输送系统落煤冲击能量缓冲监测方法，将上述落煤冲击能量缓冲监测装置安装在带式输送系统落料处皮带正下方，冲击能量收集阻尼将落煤处皮带所受冲击力转化为电信号，信号转换发送装置接收到的电信号发送到上位机，上位机根据信号情况判别落料情况，落料情况分为未落料，正常落料和超载落料三种情况，同时上位机通过调取上游皮带机的称重系统数据判断上游皮带机是否正常运行，若上游皮带机运行正常，而落料情况为未落料或超载落料，则说明出现堆料故障，通过上位机同时关闭上游皮带机的皮带驱动电机一和带式输送系统的皮带驱动电机二。
有益效果：本发明落煤冲击能量缓冲监测装置由缓冲托架及缓冲弹簧阻尼实现多层缓冲，将主要的缓冲阻尼部分转移到装置下部，在保护缓冲皮带滚筒组的基础上，减小了皮带与缓冲装置的摩擦力，同时收集阻尼能量分析落煤状况，联合控制器可起到防止堆煤故障的效果。
