Abstract
The utility model is related to anchor dynamometry technical field, especially a kind of anchor pole of roadway surrounding rock pressure measurement.Anchor pole is made of outer bar and interior bar suit, and interior bar is equipped with through-hole, and anchor pole end is equipped with protective cover；The bar wall of the outer bar is equipped with several apertures, and the bar wall of interior bar corresponds to and mounting groove is equipped at outer bar aperture, and foil gauge and small contact are fixed by spring sequence in mounting groove, and the other end of small contact is inserted into the aperture of outer bar；The installation trench bottom is equipped with mounting hole, and the conducting wire of foil gauge stretches out anchor pole after mounting hole is pierced by, along through-hole.Compared with the prior art, it has following features：First, it can accurately correspond to the measuring point of roadway surrounding rock, and make the sensing of strain ga(u)ge more accurate in the force-detecting position position that the body of rod is installed；Second is that anchor pole itself has saved material cost well also using hollow-core construction anchor pole.
Description
Technical field
The utility model is related to anchor dynamometry technical field, especially a kind of anchor pole of roadway surrounding rock pressure measurement.
Background technology
At present, coal resources in China yield increases year by year, has had many mines km working surface of deep well, lane occur
Road country rock is in high-pressure state, has become main trend using anchor rod force-measuring and supporting, is needed after suspension roof support to country rock
Pressure is monitored, and cost is greatly lowered in the appearance of hollow anchor bar.Most of force-measuring anchor stock is by resistance strain gage and bar
Body is bonded together to measure pressure value.This causes the value measured inaccurate with measuring point actual value by large error.
Utility model content
The purpose of this utility model is to provide a kind of roadway surrounding rock pressure measurement anchor poles.
The purpose of this utility model is achieved through the following channels：A kind of roadway surrounding rock pressure measurement anchor pole, anchor pole by
Outer bar is formed with interior bar suit, and interior bar is equipped with through-hole, and anchor pole end is equipped with protective cover；
The bar wall of the outer bar is equipped with several apertures, and the bar wall of interior bar corresponds to and mounting groove is equipped at outer bar aperture, peace
Foil gauge and small contact are fixed by spring sequence in tankage, the other end of small contact is inserted into the aperture of outer bar；
The installation trench bottom is equipped with mounting hole, and the conducting wire of foil gauge stretches out anchor pole after mounting hole is pierced by, along through-hole.
As advanced optimizing for this programme, on the outer bar bar wall, three groups of totally six apertures are axially and symmetrically distributed with,
There are six small contacts for respective apertures installation in interior bar.
A kind of roadway surrounding rock pressure measurement anchor pole of the utility model, compared with the prior art, it has following features：When
It can the body of rod install force-detecting position position, accurately correspond to the measuring point of roadway surrounding rock, and allow strain ga(u)ge sensing more
Accurately；Second is that anchor pole itself has saved material cost well also using hollow-core construction anchor pole.
Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the A-A of Fig. 1 to sectional view；
In figure, outer bar 1, interior bar 2, small contact 3, mounting groove 4, through-hole 5, protective cover 6, foil gauge 7.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of roadway surrounding rock pressure measurement anchor pole of the utility model, anchor pole is by 2 sets of outer bar 1 and interior bar
Dress is formed, and interior bar is equipped with through-hole 5, and anchor pole end is equipped with protective cover 6, and 6 bottom of protective cover is openable and closable end cap；The outer bar
Bar wall be equipped with several apertures, the bar wall of interior bar corresponds at outer bar aperture equipped with mounting groove 4, on the outer bar bar wall, axis
To three groups of totally six apertures are symmetrically distributed with, there are six small contacts for respective apertures installation in interior bar.It is suitable by spring in mounting groove
Sequence fixes foil gauge 7 and small contact 3, and the other end of small contact is inserted into the aperture of outer bar；The installation trench bottom is equipped with peace
Hole is filled, the conducting wire of foil gauge stretches out anchor pole after mounting hole is pierced by, along through-hole, for conducting wire is facilitated to connect pressure detecting instrument.
After roadway surrounding rock changes, pressure from surrounding rock can be deformed the small contact of stretching outer bar surface aperture, from
And foil gauge is caused to change, by the pressure value that country rock is read on data line transfer to detector.
The above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any those skilled in the art, can be without creative labor in the technical scope disclosed by the utility model
The dynamic change or replacement expected, should be covered within the scope of the utility model.Therefore, the protection model of the utility model
Enclosing be determined by the scope of protection defined in the claims.
