Abstract
本发明公开一种岩石半连续采掘工艺可伸缩运输胶带系统，包括运输胶带（1）和胶带保护装置，保护装置包括安装于运输胶带（1）靠近爆破一侧的轨道（2）、用于保护运输胶带（1）免受飞石破坏的弧形挡板（3）、用于弧形挡板（3）移动的滚轮（4）和用于驱动滚轮（4）滚动的驱动电机（6）；弧形挡板（3）通过滚轮（4）与轨道（2）可移动连接，驱动电机（6）输出轴与滚轮（4）连接。在运输胶带靠近爆破一侧设置可移动的弧形挡板，弧形挡板可以根据爆破和采掘需要任意移动位置，爆破时，弧形挡板移动到爆破位置，防止爆破产生的飞石破坏运输胶带，爆破完成后，移开弧形挡板，避免其影响正常的采掘作业。
Description
技术领域
[0001] 本发明涉及一种岩石半连续采掘工艺可伸缩运输胶带系统，属于防护装置技术领域。
背景技术
[0002] 随着露天开采技术的不断革新，大型露天矿已经从传统的间断工艺逐渐向半连续、连续工艺过渡，胶带系统发挥着越来越重要的运输作用。除了运输煤炭之外，胶带还承担着一些岩石剥离物的运输作业。但是由于岩石半连续工艺系统中，胶带布设的位置距离爆破作业区较近，经常受到飞石的影响，造成了胶带的寿命减小和设备故障率提高，并进一步导致生产效率低下和成本增加。传统的固定式胶带防护雨棚能够很好的保护胶带，但是会影响采掘作业，造成诸多不便，如何较好的保护岩石半连续工艺系统中的胶带已经成了亟待解决的问题。
发明内容
[0003] 针对上述现有技术存在的问题，本发明提供一种岩石半连续采掘工艺可伸缩运输胶带系统，在避免或消除爆破形成的飞石对于胶带的损害、降低胶带的更换频率、延长使用寿命的同时不影响采掘作业。
[0004] 为了实现上述目的，本发明采用的技术方案是:一种岩石半连续采掘工艺可伸缩运输胶带系统，包括运输胶带和胶带保护装置，胶带保护装置包括安装于运输胶带靠近爆破一侧的轨道、用于保护运输胶带免受飞石破坏的弧形挡板、用于弧形挡板移动的滚轮和用于驱动滚轮滚动的驱动电机；弧形挡板通过滚轮与轨道可移动连接，驱动电机输出轴与滚轮连接。
[0005] 进一步的，还包括柔性防护网，柔性防护网等距间隔的布置在弧形挡板上。
[0006] 进一步的，还包括“L”型支架，“L”型支架设置在弧形挡板内侧，“L”型支架上端与弧形挡板连接，“L”型支架下端延伸到轨道内侧表面。
[0007] 进一步的，所述的“L”型支架下端通过滑轮延伸到轨道内侧表面。
[0008] 本发明的有益效果是:在运输胶带靠近爆破一侧设置可移动的弧形挡板，弧形挡板可以根据爆破和采掘需要任意移动位置，爆破时，弧形挡板移动到爆破位置，防止爆破产生的飞石破坏运输胶带，爆破完成后，移开弧形挡板，避免其影响正常的采掘作业，从而达到避免或消除爆破形成的飞石对于胶带的损害、降低胶带的更换频率、延长使用寿命的同时不影响采掘作业的目的。
附图说明
[0009] 图1为本发明的立体图；
[0010] 图2为本发明胶带保护装置的主视图；
[0011] 图中:1、运输胶带，2、轨道，3、弧形挡板，4、滚轮，5、柔性防护网，6、驱动电机，7、“L”型支架。
具体实施方式
[0012] 下面结合附图对本发明作进一步说明。
[0013] 如图1所示，本岩石半连续采掘工艺可伸缩运输胶带系统，包括运输胶带I和胶带保护装置，保护装置包括安装于运输胶带I靠近爆破一侧的轨道2、用于保护运输胶带I免受飞石破坏的弧形挡板3、用于弧形挡板3移动的滚轮4和用于驱动滚轮4滚动的驱动电机6 ;弧形挡板3通过滚轮4与轨道2可移动连接，驱动电机6输出轴与滚轮4连接，驱动电机6能够正、反双向运转，驱动滚轮4和弧形挡板3在轨道2上来回运行，弧形挡板3可以根据爆破和采掘需要任意移动位置，爆破时，弧形挡板3移动到爆破位置，防止爆破产生的飞石破坏运输胶带1，爆破完成后，移开弧形挡板3，避免其影响正常的采掘作业，从而达到避免或消除爆破形成的飞石对于运输胶带I的损害、降低运输胶带I的更换频率、延长使用寿命的同时不影响采掘作业的目的。
[0014] 为了起到更好的防护效果，还包括柔性防护网5，柔性防护网5等距间隔的布置在弧形挡板3上，弧形挡板3由0.5mm厚、Im宽、1.5m高的高强度招合金材料制成，柔性防护网5由钢丝材料制成，能达到200Mpa的抗拉强度，网孔直径为5cm，长度为5m。
[0015] 如图2所示，为了提高弧形挡板3的强度，还包括“L”型支架7，“L”型支架7设置在弧形挡板3内侧，“L”型支架7上端与弧形挡板3连接，“L”型支架7下端延伸到轨道2内侧表面，通过“L”型支架7的辅助支撑来进一步提高弧形挡板3的强度。
[0016] 由于弧形挡板3需要在轨道2上来回滑动，为了减小“L”型支架7与轨道2的摩擦，“L”型支架7下端通过滑轮延伸到轨道2内侧表面，将静摩擦变为滚动摩擦，有利于弧形挡板3的滑动。
