Background technique
In the safeguard procedures of side slope Dangerous Rock Body, anchor pole plays the role of very important, but it is subjected to nature and people
For the influence of factor, causes the stress field around Dangerous Rock Body to change, influence Effects of Supporting.Traditional anchor pole monitors hand
Section is directed to single anchor pole, heavy workload, it is difficult to evaluate entire anchor rod system.Groups of people propose the intuitive early warning anchor of research and development
The invention thinking of bar, the patent No. 201521143126.0 discloses a kind of elasticity and allows pressure early warning anchor pole, long by exposed steel wire
Degree can intuitive real-time monitoring rockbolt stress；The patent No. 201611155226, which discloses, a kind of allows pressure amount with real-time monitoring
Pressure-relieving achor bar, the displacement readings unit being connected by peripheral hardware with mobile jib can allow pressure amount with directly monitoring anchor pole.But in side slope crag
In the environment of body disaster, do not have good observation condition usually, instantaneity is poor.The patent No. 201611204246.6 discloses one
Kind have the anchor pole of alarm function by pressure device and application method, by using the deformation characteristic of pressure ring spring is allowed, by anchor pole
Stress with allow the deflection of pressure ring spring to connect, can play allow pressure purpose and it is quick by observation,
Intuitively judge the stress of anchor pole.But the patent is mainly for the pressure change on the outside of anchor pole, for Dangerous Rock Body anchor pole
Internal stress variation, that knows is ominous.During protecting Dangerous Rock Body, anchor pole quantity is more, and observation condition is poor, reduces
Observation instrument requires that observed efficiency can be improved to a certain extent, but the entire support system under side slope environment is monitored
It says, remains an utterly inadequate amount.
Utility model content
In order to solve the above-mentioned technical problem, it is simple to provide a kind of structure for the utility model, easy to operate, can be intuitive high
The novel Dangerous Rock Body early warning anchor pole of effect screened whether early warning anchor pole fails.
The technical solution adopted in the utility model is: a kind of novel Dangerous Rock Body early warning anchor pole, including the body of rod, π shape sheet metal,

Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1, 2, the utility model includes the body of rod 15, pallet 5, locking nut 1, π shape sheet metal 2, early warning nut
12.It is equipped with blind hole 16 at the body of rod upper surface center, rubber bag tank 7 is equipped in blind hole 16, is full of in rubber bag tank 7 and is mixed with fluorescence
The hydraulic oil 6 of liquid；Rubber bag tank 7 squeezes out blind hole in body of rod stress deformation in order to prevent, and blind hole is stepped hole, straight at upper end
Diameter is less than lower diameter.Rubber material has elasticity and toughness is good, and the body of rod 15 is generated compression by stress, even deformed
When, the energy impermeable decompression of effective protection internal liquid, and a degree of flexible deformation is provided；When 13 internal modification of Dangerous Rock Body extremely
When to a certain degree, strain (stress) is more than 7 peak value of rubber bag tank, then the hydraulic oil with fluorescent liquid exposes along blind hole 16, indication
15 place rock mass deformation of anchor pole it is very big, pay attention to evading.
If Fig. 1 and Fig. 3-5 shows, the early warning nut 12 is screwed at 15 upper end of the body of rod, the early warning nut 12
Set the through-hole 14 there are two rectangle on side wall, the line of two through-holes 14 passes through the center of circle of early warning nut 12, in early warning nut 12
Fixing bolt 3 is equipped at the top of portion.The fixing bolt 3 is semicircular configuration, and the both ends of semicircular configuration are fixedly mounted on early warning spiral shell
12 inside top of cap.The π shape sheet metal 2 includes two sheet metals 22 and bottom plate 21, and one end of sheet metal 22 is mounted on bottom
On plate 21, two sheet metals 22 of π shape sheet metal 2 are inserted on early warning nut side wall after being each passed through corresponding fixing bolt 3
Two through-holes 14 in, the upper-end contact of the bottom plate 21 of π shape sheet metal 2 and rubber bag tank 7.Pass through spring between two sheet metals 22
4 connections, spring 4 are used to apply to the two metal sheets 22 of opening pulling force, and guidance π shape sheet metal 2 is shunk.It is set on two sheet metals 22
There are red reflex piece 10 and green reflector plate 11.12 main function of early warning nut is: protection π shape sheet metal 2, and blocks and do not open up
It opens to the reflector plate outside square hole 14, while π shape sheet metal 2 is connected by fixing bolt 3 to a certain extent, prevent from sliding.
The working principle of the utility model is as follows: as shown in Figure 1, staff has selected supporting position, the body of rod is made in drilling
15, body of rod one end is anchored using Anchor Agent 9, then injects slurry 8, pallet 5 is installed, is applied using locking nut 1 certain
Prestressing force, so far the first stage completes.By 2 tail portion two panels sheet metal 22 of π shape sheet metal pass through fixing bolt 3, along square hole 14 to
It exposes outside, so that π shape sheet metal 2 and early warning nut 12 is become an entirety with this, then allow 2 bottom plate 21 of π shape sheet metal along blind hole 16
With contacted at the top of rubber bag tank 7 in anchor pole 15, reverse early warning nut 12, installation 2 bottom circular iron plate of season π shape sheet metal extruding rubber
Capsule 7 promotes 2 front end green reflector plate 11 of π shape sheet metal to expose along square hole, while 2 middle-end little spring 4 of π shape sheet metal is drawn
Extruding force suffered by power and bottom end is at equilibrium state, and so far second stage is completed.After the utility model is installed, it is shown as green
Color；When the stress of the body of rod 15 increases, 7 stress of rubber bag tank increases elongation, and 21 stress of bottom plate promotes sheet metal to overcome 4 pulling force of spring
It is stretched out along through-hole 14, exposes red reflex piece 10, be displayed in red.When the stress of the body of rod 15 reduces, 7 stress of rubber bag tank, which reduces, to be received
When contracting, 4 pulling force of spring overcomes the extruding force of bottom end rubber bag tank 7, and forward metal piece is promoted to shrink along square hole 14, and it is anti-to withdraw green
Piece 11 is penetrated, is shown colourless.Drastic deformation occurs for the body of rod 15 inside Dangerous Rock Body, and the destruction of the body of rod 15 causes rubber bag tank 7 to rupture, interior
Hydraulic oil 6 of the portion containing fluorescent liquid flows out, and shows as visible fluorescence.
In Dangerous Rock Body disaster prevention work progress, observation π type sheet metal color change is only needed, green is normal, red
Increase for stress, no color is stress reduction, has fluorescent liquid to indicate that rock mass internal sabotage is serious, need to evade in time.It is existing with this
Field construction personnel can observe the variation of 15 internal stress of the body of rod at any time, evade in time.On the other hand, monitoring is also greatly reduced
Amount specific aim can monitor the body of rod 15 after early warning in monitoring process.Meanwhile after monitoring confirmation influence, it can revolve again
Turn early warning nut 12 to original state, adjusts spacing so that desired safe stress value is arranged, replace new red reflector plate when necessary
10 and green reflector plate 11.
