本发明是与凿岩设备配套使用,用以集尘和扩口的装置。它可用于矿山凿孔和锚杆支护联合作业。这类没备尤其适用于机械锚固或树脂锚固的矿山巷道支护。记得最初的支护方法:在顶板凿孔之后,每个孔都插入一尾部带有垫板的锚杆,由于锚杆的扩张作用使锚杆紧固在孔中。拧紧锚杆以后,与锚杆同心的岩体就被压紧了。采用树脂锚杆代替上述膨胀式锚杆,此种支护法仍必须完成三步基本操作:凿孔、插锚杆和紧固。法国No.1359297专利介绍了一种设备,该设备无需移动,而是通过绕压紧顶板的立轴轴线做简单回转实现三步操
The present invention is used with rock drilling equipment used to collect dust and flares. It can be used in coal mine tunneling and bolt support operations. This type of equipment is especially suitable for mine roadway support with mechanical anchoring or resin anchoring. Remember the original method of support: After the roof was perforated, a bolt with a backing plate was inserted into each hole, and the bolt was tightened in the hole due to the expansion of the bolt. After tightening the bolt, the rock mass concentric with the bolt is compressed. The use of resin anchor instead of the above expansion anchor, this support method still have to complete three basic steps: punching, bolt and tighten. French Patent No.1359297 describes a device that does not need to be moved but performs three steps by simply turning around the vertical axis of the compacting roof
