Description

一种类土质煤工作面全封闭掩护支架装置 技术领域
本发明涉及煤矿机械技术领域，特别涉及一种类土质煤工作面全封闭掩护支架装置。
背景技术
液压支架作为一种支护设备，在煤矿开采过程中具有广泛的应用。随着煤矿采深的不断增加，对于复杂地质条件极松软煤层工作面片帮和冒顶的防治，应该充分分析工作面工程地质条件和开采技术条件，利用支架与围岩的相互作用关系，选择合适的工作面液压支架以及相配套的支架支护体系来进行防治工作。
类土质煤作为一种新提出的创新概念，代表的是一种破碎松散的，物理性质似土非土的煤岩体，如淮南新庄孜煤矿66207工作面就是典型的类土质煤工作面，顶板较破碎，容易冒顶和掉顶，工作面的直接底板为泥岩、煤，底板岩性松软，煤壁片帮严重，常用的液压支架支护由于设计不配套，支护效果并不好，工人在这样的工作面工作，安全得不到保障。常用的化学注浆加固煤壁和顶板的方法，不仅成本过高，而且对环境产生危害，不利于工人身体健康。
发明内容
为解决上述技术问题，本发明目的是提供一种类土质煤工作面全封闭掩护支架装置，以解决类土质煤工作面冒顶、片帮严重，工人安全得不到保证的问题。

所述液压支架的上方铺设有所述碳纤维网，所述掩护梁的后部也采用所述碳纤维网覆盖住，且位于所述掩护梁后部的所述碳纤维网沿矸石的侧壁铺设，所述碳纤维网的一端固定在所述矸石的底部，所述碳纤维网的另一端从所述护帮板的前端下垂，并采用所述伸缩梁和所述护帮板将碳纤维网的下垂的部分顶在煤壁的工作面上，所述顶梁上设有滑轮，靠近所述煤壁的两个所述立柱上设有手动绞盘，钢丝绳的一端固定在所述手动绞盘上，另一端穿过所述滑轮固定在下垂的所述碳纤维网的一端；
所述护帮板包括一级护帮板和二级护帮板，所述一级护帮板长度为800mm，所述二级护帮板长度为400～700mm，所述一级护帮板与所述伸缩梁通过两个护帮千斤顶铰接；所述二级护帮板通过两个护帮千斤顶二与所述一级护帮板相铰接。
本发明所述的类土质煤工作面全封闭掩护支架装置，其中，所述碳纤维网为菱形碳纤维网。
本发明所述的类土质煤工作面全封闭掩护支架装置，其中，所述顶梁由四条主筋板、若干条横筋及上、下盖板组焊成的变截面整体箱型结构；四条所述主筋板夹空内焊有四个柱窝，所述四个柱窝与四根所述立柱顶端的球形柱头铰接；所述顶梁箱体中部设有四个套筒，所述套筒内安装弹簧、导杆、侧推千斤顶和销轴，所述套筒与侧护板通过所述销轴连接；所述顶梁前部设有铰接防倒千斤顶的连接筒座，所述侧护板的宽度为相邻两所述液压支架间距的一半。
本发明所述的类土质煤工作面全封闭掩护支架装置，其中，所述底座为整体式底座，四条主筋形成左右两个立柱安装空间，中间通过前端大过桥、后部箱型结构把左右两部分连成一体，所述底座的前端两侧分别设有角度可调的防倒滑装置。
本发明所述的类土质煤工作面全封闭掩护支架装置，其中，所述前连杆和所述后连杆的结构形式设计为分体式，均为钢板焊接的箱型结构。
本发明所述的类土质煤工作面全封闭掩护支架装置，其中，所述伸缩梁为内伸式伸缩梁，主要由顶板、腹板和立筋组成。

本发明具有以下有益效果：
1.伸缩梁千斤顶行程大于割煤步距(常规是伸缩梁千斤顶行程等于割煤步距)，能及时以高应力状态支护最新裸露出来的新鲜煤壁；护帮板由一级护帮板与二级护帮板配合使用，比传统的护帮板尺寸增大，支撑力提高，类土质煤工作面容易片、冒、漏，因此护帮板尺寸增大、液压支架的行程增加，比采煤机的截深大一些，及时支护煤壁。
2.顶梁的侧护板侧向尺寸增大，侧护板宽度为两液压支架间距的一半，类土质工作面由于顶板破碎，故相邻液压支架之间的侧护板尺寸增大，做到相邻液压支架间无空隙，避免破碎顶板冒落矸石溶入工作面。
3.碳纤维网铺设到整个回采空间上方，隔离破碎矸石，隔离了工作面空间与外部危险源，做到了本质安全。
本发明解决了类土质煤工作面冒顶、片帮严重，工人安全得不到保证的问题。
