Abstract
The utility model discloses the anchor pole stirring pin nut that the culvert support anchor rods such as a kind of mine rock gangway, coal road, traffic and water conservancy use.Its nut (1) one end is set to square (5), disposed thread (2), square (5) end of nut (1) arranges spliced eye (3), diameter is that pin (4) activity of Φ 5-7mm is fastened in spliced eye (3), and nut (1) pin (4) and anchor pole (6) activity are fixed together.Because the utility model devises pin nut, with resin explosive roll conbined usage, supporting is timely, and pretension and bearing capacity greatly, have stronger control ability and stability to the distortion of roadway surrounding rock, pin diameter design is reasonable, and construction technology is simple, can realize Fast Installation, be used alone, being conducive to tunnel, goaf across falling, reducing cost of production.
Description
Technical field: the utility model relates to the anchor pole stirring pin nut that the culvert support anchor rods such as a kind of mine rock gangway, coal road, traffic and water conservancy use.
Background technology: excessively current, at the anchor pole that the culvert top boards or two such as mine rock gangway, coal road, traffic and water conservancy help supporting to use, be mostly the anchor pole of band plain nut, utilize resin explosive roll to reinforce, pretension and low bearing capacity, firmness is inadequate, poor stability.
Utility model content: it is timely that the purpose of this utility model there are provided a kind of supporting, pretension and bearing capacity greatly, stir pin nut to the anchor pole that the distortion of roadway surrounding rock has stronger control ability and stability to use.
The technical scheme that the utility model is adopted for achieving the above object is: its nut 1 one end is set to square 5, disposed thread 2, square 5 ends of nut 1 arrange spliced eye 3, diameter is that pin 4 activity of Φ 5-7mm is fastened in spliced eye 3, and nut 1 pin 4 and anchor pole 6 activity are fixed together.
The beneficial effects of the utility model are: owing to devising pin nut, with resin explosive roll conbined usage, supporting is timely, and pretension and bearing capacity greatly, have stronger control ability and stability to the distortion of roadway surrounding rock, pin diameter design is reasonable, and construction technology is simple, can realize Fast Installation, be used alone, being conducive to tunnel, goaf across falling, reducing cost of production.
Accompanying drawing illustrates: Fig. 1 is front view of the present utility model
Fig. 2 is the top view of Fig. 1
Detailed description of the invention: as shown in Figure 1 and Figure 2, its nut 1 one end is set to square 5, disposed thread 2, and square 5 ends of nut 1 arrange spliced eye 3, diameter is that pin 4 activity of Φ 5-7mm is fastened in spliced eye 3, and nut 1 pin 4 and anchor pole 6 activity are fixed together.
As shown in Figure 1 and Figure 2, described diameter is Φ 6mm, and metallic gasket and plastic spacer are movably connected between nut 1 on anchor pole 6 and pallet.
Operation sequence of the present utility model is: 1, beat bolthole: help to beat bolthole by design bolthole position monomer jumbolter at back or two;
2, anchor pole is assembled: in the following order: the pin nut-body of rod-metal washer-plastic washer-pallet is assembled;
3, resin medicine is installed: push at the bottom of hole by resin explosive roll at leisure with anchor pole;
4, agitating resin: facility and anchor nut are coupled together with adapter sleeve, then starts facility and advances while stirring, stops stirring after stirring 20S-30S;
5, fastening anchor pole: after stopping stirring 20S, rerun rig, and the pin on nut is cut off and tightened by nut under the drive of rig, and rockbolt installation is complete.
