Description
Technical field
It is particularly a kind of for large-scale analog simulation the utility model is related to the measurement of similarity simulation experiment roadway surrounding rock stress
Test the rockbolt installation device in tunnel.
Background technology
At present, it in laboratory similarity simulation experiment process, measures roadway surrounding rock stress and roadway surrounding rock is propped up
In the instrument of shield, the inconvenient and installation process of most of operation is complicated, there are no a kind of at low cost and installation very easily
Device.It is particularly longer in similarity simulation experiment tunnel and in the case that space is small, need measurement distance access adit position farther out
Surrouding rock stress, experimental provision requirement can be more special.
Utility model content
The purpose of this utility model is to provide a kind of rockbolt installation devices for large-scale similarity simulation experiment tunnel.
The purpose of this utility model is achieved through the following channels：A kind of anchor for large-scale similarity simulation experiment tunnel
Bar erecting device, fixed link both ends are separately installed with a magnet base, and fixed link stage casing is equipped with disk, and disk bottom surface is along the center of circle
Symmetrical dress is there are three installing frame, and the interior frame bottom of installing frame is fixed with pullover, spring is set on pullover, and the spring other end is fixed
There is small-sized electrical drilling machine, force-measuring anchor stock is installed on the electric drill mouth of small-sized electrical drilling machine, small-sized electrical drilling machine is fixed on slide plate, slide plate both sides
End is movably installed in sliding slot guide rail, and sliding slot guide rail is installed in the same direction with installing frame.
As advanced optimizing for this programme, the disk is fixed on by metal hose clamp in fixed link.
As advanced optimizing for this programme, the small-sized electrical drilling machine is fixed on by soft iron item and screw on slide plate.
A kind of rockbolt installation device for large-scale similarity simulation experiment tunnel of the utility model, the device simple installation,
It is required at low cost and easy to operate, it is particularly possible to realize and the stressing conditions of tunnel deep wall rock are monitored, it is no longer necessary to people
For the object big with the quality such as iron hammer and rigidity carry out shock anchor pole.
Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the utility model side structure schematic view；
Fig. 2 is the utility model overlooking the structure diagram；
In figure, magnet base 1, fixed link 2, metal hose clamp 3, disk 4, sliding slot guide rail 5, force-measuring anchor stock 6, small-sized electrical drilling machine 7,
Pullover 8, installing frame 9, spring 10, slide plate 11, soft iron item 12.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of rockbolt installation device for large-scale similarity simulation experiment tunnel of the utility model, Gu
2 both ends of fixed pole are separately installed with a magnet base 1, and disk 4 is fixed on by metal hose clamp 3 in fixed link 2.Disk bottom surface is along circle
The heart is symmetrically filled there are three installing frame 9, and the interior frame bottom of installing frame 9 to be fixed with pullover 8, spring 10 is set on pullover, spring is another
One end is fixed with small-sized electrical drilling machine 7, installs force-measuring anchor stock 6 on the electric drill mouth of small-sized electrical drilling machine, the small-sized electrical drilling machine passes through
Soft iron item 12 and screw are fixed on slide plate, and 11 two side ends of slide plate are movably installed in sliding slot guide rail 5, sliding slot guide rail 5 and installation
Frame 9 is installed in the same direction.
The utility model operating process is as follows：The fixed link one end being fixed on magnet base is fixed on tunnel by magnetic force
On interior experimental rig, one end is on the magnet base outside tunnel.Disk is fixed in fixed link by metal hose clamp, baffle and
Block pannel is vertical with disk, surrounds pullover, and spring pocket is on the pullover surrounded by baffle, termination point of anchor rod and wall table
Face contacts, and the spring of support anchors and small-sized drill is made to be in compressive state, small-sized brill is hit to be fixed on by soft joint strip and screw
On the slide plate of sliding slot guide rail, the line trap of small-sized drill is involved out of tunnel, is electrified.In use, open small-sized electric drill
Switch, anchor pole brill are dug and are hit to spring nature deformation position by the elastic force that spring is compressed during hitting roadway surrounding rock automatically
Stop, anchor pole is squeezed into roadway surrounding rock at this time, support action is played to tunnel, while when the country rock that drills changes, anchor
Also stress changes strain ga(u)ge on bar, and the conducting wire by being connected with strain ga(u)ge is passed on secondary meter and measured therewith
Corresponding stress variation value.
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.
