Abstract
本实用新型涉及一种在煤矿掘进过程中使用的防爆盒，属煤矿设备技术领域，为解决现有防爆盒设计过于简单不能完好起到防爆以及控制振动问题而设计。本实用新型主要包括弧形钢板、水袋槽、填充橡胶、出孔、入孔和填充海绵。该防爆盒较之以往的防爆盒特殊之处在于其外部四面设有弧形钢板，用来反射以及分散爆轰波，在水袋槽内部放置水袋，这样在一定程度上吸收爆轰波的能量，内部设置的填充橡胶具有很好的压缩效果，也可吸收一部分爆轰波的能量，填充海绵疏松多孔的构造，使爆轰波传播过程中产生一定能量损失的同时也起到很好地缓冲效果。锚杆通过入孔进出孔出，通过螺丝或锚杆托盘固定即可工作，在保证有效降低爆破振动的前提下实用性强。
Description
技术领域
[0001]本实用新型属煤矿设备技术领域，具体涉及一种用于降低爆破振动的防爆盒。
背景技术
[0002]在煤矿工程、隧道工程等领域施工中，为了对锚杆受力进行监测，需在锚杆端部设置测力计，而锚杆往往设置在离掌子面很近的位置，采用爆破手段对巷道掘进过程中，爆破振动以及产生的爆轰波对锚杆测力计造成了巨大的损害，常常使得锚杆测力计彻底无法工作。传统的防爆盒仅仅为一方形盒，不具备缓冲性能，防爆效果很差。因此，需要研制一种矿用防爆盒，在爆破施工过程中，可以很好地反射和分散爆轰波，在工作过程中可以起到很好的缓冲效果，可以最大程度的保护锚杆测力计不受破坏。
发明内容
[0003]本实用新型的在于提出一种矿用防爆盒。该防爆盒易于安装和拆卸，能够改变爆轰波的传播路线，并且可以使得一部分爆轰波相互抵消，并且可以吸收爆轰波的一部分能量，其填充材料的良好的压缩性能可以起到很好的缓冲效果，最大程度保护了设备不受破坏。该防爆盒主要是应用于地下工程爆破施工中对锚杆上设置的测力计进行保护，将爆破对其造成的损害降到最低。
[0004]本实用新型主要包括弧形钢板、水袋槽、填充橡胶、出孔、入孔和填充海绵；四块弧形钢板和水袋槽的连接方式为焊接，水袋槽内部通过树脂类胶液粘结填充橡胶，填充橡胶内部通过树脂类胶液粘结填充海绵，填充海绵所组成的腔体为入孔，防爆盒底部设置有出孔，将设置在锚杆上的测力计放进入孔，锚杆通过出孔穿过，在爆破的过程中，可以对测力计起到一定程度的保护作用。
[0005]为实现本实用新型的目的，采用的技术方案是:一种矿用防爆盒，其区别以往的防爆盒，该防爆盒的外部设置有四个弧形钢板，四个弧形钢板用于反射并分散爆轰波，弧形钢板内部设有水袋槽，水袋槽内置水袋，在爆破过程中吸收爆轰波的能量，填充橡胶和填充海绵具有很好的压缩性能，可以起到缓冲作用，而填充海绵疏松多孔的结构，也可以对爆轰波的传播产生阻挡，将测力计放进入孔，可以保护其免受破坏。
[0006]通过采用前述技术方案，本实用新型的有益技术效果是:提出了 一种切实可行、易于施工的防爆盒。该防爆盒施工简便，易于安装和拆卸。其外部设置的弧形钢板对爆轰波进行反射并改变其传播路线，与此同时，在水袋槽内置水袋，这一系列的方式，大大降低了爆轰波的能量，填充橡胶和填充海绵具有很好的压缩性能，可以最大程度地对测力计进行保护，而且其安装和拆卸流程简单可行，最大程度上保证了测力计不受破坏，该防爆盒在整体上保证了测力计能够在爆破环境中长时间正常工作。
附图说明
[0007]图1为一种矿用防爆盒的俯视图。
[0008]图2为一种矿用防爆盒的剖视图。
具体实施方式
[0009]下面结合附图对本实用新型进行详细说明:本实用新型一种制备橡胶颗粒混凝土试件的实验模具包括弧形钢板1、水袋槽2、填充橡胶3、出孔4、入孔5、填充海绵6。
[0010] 一种矿用防爆盒的外部由四块弧形钢板I构成，在每块四块弧形钢板I内部设有两个水袋槽2，弧形钢板I和水袋槽2的连接方式为焊接，水袋槽2内部通过树脂类胶液粘结填充橡胶3，填充橡胶3内部通过树脂类胶液粘结填充海绵6，填充海绵6所组成的腔体为入孔5，防爆盒底部设置有出孔4，将设置在锚杆上的测力计放进入孔4，锚杆通过出孔5穿过，通过螺丝或锚杆托盘固定即可工作。具体使用操作:将预先按要求设计好的水袋放入水袋槽2中，锚杆穿过出孔5，将设置在锚杆上的测力计放进入孔4内，然后在防爆盒底部通过螺丝或锚杆托盘固定，当进行爆破施工时，爆轰波经过弧形钢板I的反射使得一部分爆轰波相互抵消，一部分爆轰波分散至其他方向，通过水袋槽2内的水袋吸收一部分爆轰波的能量，填充橡胶3和填充海绵6具有很好的压缩性能，可以起到缓冲作用，填充海绵6疏松多孔的结构，也可以阻碍爆轰波的传播，并且当防爆盒整体振动时，填充橡胶3和填充海绵6均可对测力计起到很好的保护作用，保证其免受破坏。
[0011]当然，以上说明仅仅并非是对本实用新型的限制，本实用新型也并不仅限于上述举例，应当说明的是，本技术领域的技术人员在本实用新型的实质范围内做出的变化、改型、添加或替换，也属于本实用新型的保护范围。
