Space is saved with thin wire 4.Meanwhile the photoelectricity open circuit 1 built in monitoring point early warning nut 9 is connect into power supply 13 on demand, if
Put work light 12, to judge the region whether normal power supply（Work）.When tunnel, which occurs, for monitoring point is caving disaster, anchor
Bar is destroyed, drops, so as to trigger conducting wire to be pulled off to form open circuit, ground work light 12 extinguishes.Power supply 13 is in this practicality
Main function in new is：Via work light 12 can determine that monitoring dot circuit whether normal operation, which is determined with this
Whether measuring point has occurred and that disaster.
The operation principle of the utility model is as follows：As shown in Figure 1, in use, by conventional procedures installation anchor pole, the body of rod is squeezed into
8, Anchor Agent 14 is injected, sets gradually pallet 16 and locking nut 17, prestressing force is set, completes suspension roof support work.Closure is pre-
Photoelectricity open circuit 1 switchs in alert nut（Switch installation site does not limit）, due between phototriode and relay without every
Plate, when circuit connects external power 13, circuit turn-on triggers audible alarm, is directed at 9 middle two pins of early warning nut inserts at this time
Hole 18 is rotated along 8 screw thread lines of the body of rod to be pushed into, until the baffle 20 on copper sheet 19 blocks 1 both ends of photoelectricity open circuit, alarm song
Release；On the other hand, pressure on the number display 10 is checked, after copper sheet 19 is connected with copper groove 5, forming circuit, pressure on the number is shown
Show that device 10 shows that stress value suffered by foil gauge 6, earth's surface work light 12 normally light at this time, represent that installation is complete.
The utility model is a kind of multifunctional monitoring early warning anchor pole, has monitoring early period, timely early warning and Post disaster relief three
Kind function.In use, keeping power supply 13 to start shooting, worker is before tunnel working region is entered, where pressure on the number display 10
Region, understands workspace anchor stress environment, if any exception, in time disposal；Worker is in tunnel operation, if 15 stress field of country rock
Change, 8 internal hydraulic pressure capsule 7 of the body of rod cause baffle 20 to be moved to non-along 18 opening direction racking strain piece 6 of jack to strain threshold values
Blocked area, the conducting of photoelectricity open circuit 1 trigger audible alarm, and operating personnel withdraws immediately；Withdrawn not in time if running into, personnel's quilt
Tired, 9 built-in circuit of monitoring point early warning nut open circuit, ground work light 12 is dim, thus ground personnel can determine that disaster-stricken
Evil region, so as to instruct the rescue work after calamity.
