本发明专利技术公开一种掘进工作面锚杆支护前探梁,由锚杆和双销铰接顶梁组成,在锚杆上通过螺母和垫板固定有马鞍形上连接板,在上连接板的两端悬吊有两根等长的通丝螺栓,在螺栓上旋装有上卡紧螺母和下卡紧螺母,在上卡紧螺母和下卡紧螺母之间的螺栓杆上穿装有中间卡板和倒马鞍形下连接板,所述的双销铰接顶梁卡装在中间卡板和下连接板之间。与现有技术相比,本发明专利技术具有能够随巷道或隧道起伏不平的顶面进行调整、使顶梁紧贴岩面、增大接触面,防止冒顶落石的优点。

Front beam of bolt support in heading face

The invention discloses a bolt excavation face support forestope, composed of bolt and double pin hinged top beam on the bolt through the nut and the backing plate is fixed on the connecting plate of the saddle, suspension at both ends of the upper connecting plate has two harness bolt length, bolt screwed in the upper clamping nut and a lower clamping nut, bolt bar on the card between the nut and the card nut is arranged on the middle plate and inverted saddle shaped lower connecting plate, double pin hinge roof the card installed in the middle plate and a lower connecting plate between. Compared with the prior art, the invention has the advantages of adjusting the top surface of a tunnel or a tunnel, preventing the roof beam from sticking to the rock surface, increasing the contact surface and preventing falling roof and falling rocks.
